            Health and  Retirement  Properties  Trust,  a Maryland  real  estate
investment  trust (the "Company" or "HRP"),  hereby  offers,  upon the terms and
subject to the  conditions  set forth in this  Prospectus  and the  accompanying
Letter of  Transmittal  (the  "Letter of  Transmittal"),  to exchange its 6 3/4%
Senior  Notes  Due  2002  (the  "New  Notes"),  in an  offering  which  has been
registered under the Securities Act of 1933, as amended (the "Securities  Act"),
pursuant to a  Registration  Statement of which this  Prospectus  constitutes  a
part, for an equal  principal  amount of its outstanding 6 3/4% Senior Notes due
2002 (the "Old  Notes"),  of which an  aggregate  of  $150,000,000  in principal
amount is  outstanding  as of the date hereof (the  "Exchange  Offer").  The New
Notes and the Old Notes are  sometimes  referred to herein  collectively  as the
"Notes."  The form and terms of the New  Notes  will be the same as the form and
terms  of the Old  Notes  except  that  the New  Notes  will  not  bear  legends
restricting  the  transfer  thereof.  The New Notes will be  obligations  of the
Company  entitled  to  the  benefits  of  the  Indenture  and  the  Supplemental
Indenture,  each dated as of December 18, 1997 (collectively,  the "Indenture"),
by and between the Company and State Street Bank and Trust  Company,  as trustee
(the  "Trustee"),  relating to the Notes.  See  "Description  of the New Notes."
Following the  completion of the Exchange  Offer,  none of the New Notes will be
entitled to any rights  under the  Registration  Rights  Agreement,  dated as of
December 18, 1997 (the  "Registration  Rights  Agreement"),  including,  but not
limited to,  contingent  increases  in the interest  rate  provided for pursuant
thereto.

          THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE

               OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
                  ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
                       REPRESENTATION TO THE CONTRARY IS A
                                CRIMINAL OFFENSE.
                             ----------------------


               The date of this Prospectus is _____________, 1998.

<PAGE>




         The  Company  will accept for  exchange  any and all Old Notes that are
validly  tendered on or prior to 5:00 p.m.,  New York City time, on the date the
Exchange Offer expires,  which will be ______________,  1998 unless the Exchange
Offer is extended (the "Expiration Date"). Tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration  Date. The
Exchange Offer is not conditioned upon any minimum principal amount of Old Notes
being tendered for exchange.

         The Old Notes were initially represented by a single,  permanent global
note (the "Global Note"), which was deposited with the Trustee, as custodian for
The Depository Trust Company ("DTC"),  and registered in the name of Cede & Co.,
DTC's nominee,  for credit to an account of a direct or indirect  participant in
DTC.  The New Notes  exchanged  for the Old Notes  that are  represented  by the
Global  Note will  continue  to be  represented  by a  permanent  global note in
definitive,  fully registered  form,  registered in the name of a nominee of DTC
and  deposited  with the Trustee as  custodian,  unless the  beneficial  holders
thereof  request  otherwise.  See  "Description  of the  New  Notes--Book  Entry
System."  Notes may be tendered only in  denominations  of $100,000 and integral
multiples of $1,000 in excess thereof.

         Interest on the New Notes will be payable  semi-annually  in arrears on
June  18 and  December  18 of each  year  (each  an  "Interest  Payment  Date"),
commencing  June 18, 1998 to the person in whose name the applicable New Note is
registered  at the close of business on the date (whether or not a business day)
15 calendar days preceding the applicable  Interest Payment Date or December 18,
2002 (the "Maturity Date").  Interest on the New Notes will accrue from the most
recent date to which  interest has been paid on the Old Notes or, if no interest
has been paid,  from December 18, 1997.  Accordingly,  interest that has accrued
since the last  Interest  Payment Date or December 18, 1997 (as the case may be)
on the Old Notes accepted for exchange will cease to be payable upon issuance of
the New  Notes.  Untendered  Old  Notes  that are not  exchanged  for New  Notes
pursuant to the  Exchange  Offer will remain  outstanding  and  continue to bear
interest at a rate of 6 3/4% per annum after the Expiration Date.

         Based on no-action  letters  issued by the staff of the  Securities and
Exchange  Commission (the  "Commission") to third parties,  the Company believes
the New Notes issued  pursuant to the Exchange  Offer may be offered for resale,
resold  and  otherwise  transferred  by a  holder  thereof  (other  than  (i)  a
broker-dealer  who acquires  such New Notes  directly from the Company to resell
pursuant to Rule 144A or any other available  exemption under the Securities Act
or (ii) a person that is an affiliate of the Company (within the meaning of Rule
405 under the Securities  Act)) without  compliance  with the  registration  and
prospectus  delivery  provisions of the Securities Act, provided that the holder
is acquiring the New Notes in the ordinary course of such holder's  business and
is not participating, and has no arrangement or understanding with any person to
participate,  in the distribution of the New Notes. Holders of Old Notes wishing
to accept the Exchange Offer must represent to the Company that such  conditions
have been met.  Each  broker-dealer  that receives New Notes for its own account
pursuant  to the  Exchange  Offer  must  acknowledge  that  it  will  deliver  a
prospectus  in  connection  with any  resale of such New  Notes.  The  Letter of
Transmittal  states that by so acknowledging  and by delivering a prospectus,  a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning  of the  Securities  Act.  This  Prospectus,  as it may  be  amended  or
supplemented  from time to time,  may be used by a  broker-dealer  in connection
with  resales of New Notes  received  in  exchange  for Old Notes where such Old
Notes  were  acquired  by  such  broker-dealer  as  a  result  of  market-making
activities or other trading  activities.  The Company has agreed for a period of
at least 120 days  after the  consummation  of the  Exchange  Offer to make this
Prospectus  available to any  broker-dealer  for use in connection with any such
resale. See "Plan of Distribution."

         Prior to the Exchange  Offer,  there has been no public  market for the
Old Notes or the New Notes. The Company does not intend to list the New Notes on
any securities  exchange or to seek approval for quotation through any automated
quotation  system.  There can be no assurance  that an active market for the New
Notes will develop. To the extent that a market for the New Notes develops,  the
market value of the New Notes will depend on market  conditions  (such as yields
on  alternative  investments),   general  economic  conditions,   the  Company's
financial  condition and other  conditions.  Such conditions might cause the New
Notes,  to the extent that they are actively  traded,  to trade at a significant
discount from the face value.

         The Company will not receive any proceeds from the Exchange Offer.  The
Company has agreed to bear the expenses of the Exchange Offer. No underwriter is
being used in connection with the Exchange Offer.

         THE  EXCHANGE  OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY  ACCEPT
SURRENDERS FOR EXCHANGE FROM,  HOLDERS OF OLD NOTES IN ANY JURISDICTION IN WHICH
THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE WITH THE
SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.

         NEITHER THE FACT THAT A REGISTRATION  STATEMENT OR AN APPLICATION FOR A
LICENSE  HAS BEEN  FILED  WITH THE  STATE OF NEW  HAMPSHIRE  NOR THE FACT THAT A
SECURITY IS  EFFECTIVELY  REGISTERED OR A PERSON IS LICENSED IN THE STATE OF NEW
HAMPSHIRE  CONSTITUTES A FINDING BY THE SECRETARY OF STATE OF NEW HAMPSHIRE THAT
ANY DOCUMENT FILED UNDER RSA 421-B IS TRUE, COMPLETE AND NOT MISLEADING. NEITHER
ANY SUCH FACT NOR THE FACT THAT AN EXEMPTION  OR  EXCEPTION  IS AVAILABLE  FOR A
SECURITY OR A  TRANSACTION  MEANS THAT THE  SECRETARY OF STATE HAS PASSED IN ANY
WAY UPON THE MERITS OR  QUALIFICATIONS  OF, OR RECOMMENDED OR GIVEN APPROVAL TO,
ANY PERSON,  SECURITY,  OR  TRANSACTION,  IT IS UNLAWFUL TO MAKE, OR CAUSE TO BE
MADE,  TO ANY  PROSPECTIVE  PURCHASER,  CUSTOMER OR CLIENT,  ANY  REPRESENTATION
INCONSISTENT WITH THE PROVISIONS OF THIS PARAGRAPH.

Accrued Interest on the New

                              last Interest  Payment Date on which  interest was
                              paid on the Old Notes,  or if interest has not yet

Termination                   The Company may terminate the Exchange Offer if it
                              determines  that its  ability to proceed  with the

                              redeemable, at the option of the Company, in whole
                              or in part, at a redemption price equal to the sum
                              of (i) the principal amount of the New Notes being

                              Make-Whole Amount. On and after such date, the New

                              Notes  being  redeemed,  plus  accrued  and unpaid
                              interest to but excluding the redemption date.

                              (1) Neither the  Company  nor any  Subsidiary  (as
                              defined) may incur any Debt (as defined) if, after
                              giving effect  thereto,  the  aggregate  principal
                              amount of all outstanding  Debt of the Company and
                              its  Subsidiaries  on  a  consolidated   basis  is
                              greater  than  60% of  the  sum  ("Adjusted  Total
                              Assets") of (i) the Total  Assets (as  defined) of
                              the Company and its  Subsidiaries as of the end of
                              the  most  recent  calendar  quarter  and (ii) the
                              purchase  price  of  any  real  estate  assets  or
                              mortgages receivable  acquired,  and the amount of
                              any securities  offering proceeds received (to the
                              extent that such proceeds were not used to acquire
                              real estate assets or mortgages receivable or used
                              to reduce Debt),  by the Company or any Subsidiary
                              since the end of such calendar quarter,  including
                              those  proceeds  obtained in  connection  with the
                              incurrence of such additional Debt.

                              (2) Neither the  Company  nor any  Subsidiary  may
                              incur any Secured  Debt if,  after  giving  effect
                              thereto,  the  aggregate  principal  amount of all
                              outstanding  Secured  Debt of the  Company and its
                              Subsidiaries  on a  consolidated  basis is greater
                              than 40% of the Company's Adjusted Total Assets.

                              (3) Neither the  Company  nor any  Subsidiary  may
                              incur any Debt,  if, after giving effect  thereto,
                              the ratio of  Consolidated  Income  Available  for
                              Debt  Service  (as  defined)  to the  Annual  Debt
                              Service  (as  defined)  for the  four  consecutive
                              fiscal  quarters most recently  ended prior to the

                              incurred  shall  have been less than 1.5x on a pro
                              forma  basis  after   giving   effect  to  certain
                              assumptions.

                              entered  into by the Company  and  Merrill  Lynch,
                              Pierce,  Fenner & Smith Incorporated (the "Initial

                              "Issue Date"), a registration  statement under the
                              Securities Act (the "Exchange  Offer  Registration
                              Statement")  with respect to the  Exchange  Offer;
                              (ii)  cause  the   Exchange   Offer   Registration
                              Statement to be declared effective within 150 days
                              of the Issue Date;  and (iii)  cause the  Exchange
                              Offer to be consummated within the sooner to occur
                              of  45  days  after  the  effective  date  of  the
                              Exchange Offer Registration  Statement or 180 days
                              after the Issue  Date.  In certain  circumstances,

(1)      The Company's Funds From Operations ("FFO") represents net income (computed in accordance with
         generally accepted accounting principles ("GAAP")), before gain or loss on sale of properties and
         extraordinary items, depreciation and other non-cash items and includes HRP's pro rata share of HPT's
         FFO.  Management considers FFO to be a measure of the financial performance of an equity REIT that
         provides a relevant basis for comparison among REITs.  FFO does not represent cash flow from operating
         activities (as determined in accordance with GAAP) and should not be considered as an alternative to net
         income as an indicator of the Company's financial performance or to cash flows as a measure of liquidity.

(2)      Amounts represent  dividends declared with respect to the period shown.
         Distribution in excess of net income  generally  constitute a return of
         capital.

                       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:

                                                            For the year ended December 31,

</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 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 expense, 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.

                                 USE OF PROCEEDS

         The Company will not receive any cash proceeds from the issuance of the
New  Notes  offered  hereby.  In  consideration  for  issuing  the New  Notes as
contemplated in this Prospectus,  the Company will receive in exchange Old Notes
in like principal amount, the terms of which are identical to the New Notes. The
Old Notes surrendered in exchange for New Notes will be retired and canceled and
cannot be  reissued.  Accordingly,  issuance of the New Notes will not result in
any increase in the indebtedness of the Company.

         The net  proceeds  to the  Company  from the sale of the Old  Notes was
approximately  $149  million.  The net  proceeds  were used in December  1997 to
reduce amounts  outstanding under the Company's $450 million unsecured revolving
credit facility with a syndicate of banks (the "Bank Credit Facility"),  and for
general business purposes.  Outstanding  amounts under the Company's Bank Credit
Facility  bear  interest,  at the  Company's  option,  at LIBOR plus a margin or
prime,  and the Bank Credit Facility  expires in 2001. At December 10, 1997, the
effective  interest rate on outstanding  amounts under the Bank Credit  Facility
was 6.55% per annum, and at March 5, 1998 such effective  interest rate was 6.4%
per annum.


                               THE EXCHANGE OFFER

General

         In connection with the sale of the Old Notes,  the Company entered into
the Registration  Rights Agreement,  which requires the Company to file with the
Commission a registration  statement under the Securities Act with respect to an
issue of senior  notes of the  Company  with  terms  identical  to the Old Notes
(except with respect to restrictions on transfer) and to use its best efforts to
cause such  registration  statement to become effective under the Securities Act
by no later than May 15, 1998 and, upon the  effectiveness of such  registration
statement,  to offer to the  holders  of the Old  Notes the  opportunity,  for a
period of not less than 20 business  days (or longer if  required by  applicable
law) from the date the notice of the Exchange  Offer is mailed to holders of the
Old Notes, to exchange their Old Notes for a like principal amount of New Notes.
The Exchange Offer is being made pursuant to the  Registration  Rights Agreement
to satisfy the Company's obligations thereunder.

         Under  existing   interpretations   of  the  staff  of  the  Commission
enunciated in no-action letters issued to third parties, the New Notes would, in
general,  be  freely  transferable  after the  Exchange  Offer  without  further
registration  under the  Securities  Act by holders  thereof  (other  than (i) a
broker-dealer  who acquires  such New Notes  directly from the Company to resell
pursuant to Rule 144A or any other available  exemption under the Securities Act
or (ii) a person that is an affiliate of the Company  within the meaning of Rule
405 under the Securities  Act),  without  compliance with the  registration  and
prospectus  delivery  provisions of the Securities  Act,  provided that such New
Notes are acquired in the  ordinary  course of such  holders'  business and such
holders have no arrangements  with any person to participate in the distribution
of such New Notes.  Eligible  holders  wishing to accept the Exchange Offer must
represent to the company that such conditions have been met. Each  broker-dealer
that receives New Notes for its own account  pursuant to the Exchange Offer must
acknowledge  that it will deliver a prospectus in connection  with any resale of
such New Notes.

         In the event that (i) the Exchange Offer is not consummated  within the
earlier of 45 days of the  effective  date of the  Exchange  Offer  Registration
Statement or 180 days after the Issue Date; or (ii) in the case of any holder of
Old Notes that  participates in the Exchange Offer, such holder does not receive
freely  tradeable New Notes on the date of such  exchange,  the Company will, at
its own  expense,  (a) as promptly  as  practicable,  file a shelf  registration
statement,  (b) use its best efforts to cause such Shelf Registration  Statement
to be declared  effective  under the  Securities  Act as promptly as practicable
after  the  filing of such  Shelf  Registration  Statement  and (c) use its best
efforts to keep effective such Shelf  Registration  Statement in order to permit
the prospectus forming a part thereof to be usable by holders of Old Notes for a
period of two years after the effective date of the Shelf Registration Statement
(or, the shorter  period  provided by Rule 144(k) under the  Securities  Act) or
such shorter  period that will  terminate  when all the Old Notes covered by the
Shelf  Registration  Statement have been sold pursuant to the Shelf Registration
Statement.

Terms of the Exchange Offer

         Upon  the  terms  and  subject  to the  conditions  set  forth  in this
Prospectus  and in the  accompanying  Letter of  Transmittal,  the Company  will
accept all Old Notes validly tendered prior to 5:00 p.m., New York City time, on
the Expiration  Date. The Company will issue $100,000 in principal amount of New
Notes (and  integral  multiples of $1,000 in excess  thereof) in exchange for an
equal  principal  amount of  outstanding  Old Notes tendered and accepted in the
Exchange  Offer.  Holders may tender some or all of their Old Notes  pursuant to
the Exchange Offer in any  denomination of $100,000 or in integral  multiples of
$1,000 in excess thereof.

         The form and  terms of the New  Notes  will be the same as the form and
terms  of the Old  Notes  except  that  the New  Notes  will  not  bear  legends
restricting the transfer  thereof.  The New Notes will evidence the same debt as
the Old Notes.  The New Notes will be issued  under and entitled to the benefits
of the Indenture.

         As of the  date  of this  Prospectus,  $150,000,000  million  aggregate
principal amount of the Old Notes are outstanding and CEDE & Co., the nominee of
DTC, is the only registered  holder thereof.  In connection with the issuance of
the Old Notes, the Company arranged for the Old Notes to be eligible for trading
in the Private Offering,  Resale and Trading through Automated Linkages (PORTAL)
Market, the National Association of Securities Dealers' screen based,  automated
market  trading of  securities  eligible for resale  under Rule 144A,  and to be
issued and  transferable  in book-entry  form through the facilities of DTC. The
New Notes will also be issuable and transferable in book-entry form through DTC.

         This Prospectus,  together with the accompanying Letter of Transmittal,
is being sent to all registered  holders as of  ____________,  1998 (the "Record
Date").

         The Company shall be deemed to have accepted validly tendered Old Notes
when,  as and if the  Company  has given oral or written  notice  thereof to the
Exchange Agent.  See "Exchange  Agent." The Exchange Agent will act as agent for
the  tendering  holders of Old Notes for the purpose of receiving New Notes from
the Company and delivering New Notes to such holders.

         If any tendered  Old Notes are not accepted for exchange  because of an
invalid  tender or the  occurrence  of certain  other  events set forth  herein,
certificates  for any  such  unaccepted  Old  Notes  will be  returned,  without
expense,  to the tendering  holder thereof as promptly as practicable  after the
Expiration Date.

         The  Company  will pay all  charges and  expenses,  other than  certain
applicable  taxes,  in  connection  with  the  Exchange  Offer.  See  "Fees  and
Expenses."

         Holders of Old Notes do not have any  appraisal or  dissenters'  rights
under  applicable  Maryland law or the Indenture in connection with the Exchange
Offer.  The Company intends to conduct the Exchange Offer in accordance with the
provisions of the Registration Rights Agreement and the applicable  requirements
of the Exchange Act and the rules and regulations of the Commission  thereunder.
Old Notes that are not tendered  for exchange in the Exchange  Offer will remain
outstanding  and  continue to accrue  interest,  but will not be entitled to any
rights or benefits under the Registration Rights Agreement.

         Each holder of Old Notes who wishes to exchange Old Notes for New Notes
in the  Exchange  Offer  will  be  required  to  make  certain  representations,
including that (i) it is neither an affiliate of the Company nor a broker-dealer
tendering Old Notes acquired directly from the Company for its own account, (ii)
any New Notes to be received by it were  acquired in the ordinary  course of its
business and (iii) at the time of  commencement of the Exchange Offer, it has no
arrangement  with any person to  participate  in the  distribution  (within  the
meaning of the Securities Act) of the New Notes. In addition, in connection with
any resales of New Notes, any  broker-dealer (a  "Participating  Broker-Dealer")
who  acquired  Old  Notes  for its own  account  as a  result  of  market-making
activities or other  trading  activities  must deliver a prospectus  meeting the
requirements  of the  Securities  Act in  connection  with any resale of the New
Notes.  See "Plan of  Distribution."  The Commission has taken the position,  in
no-action letters issued to third parties, that Participating Broker-


                                       8
<PAGE>

Dealers may fulfill their prospectus  delivery  requirements with respect to the
New Notes (other than a resale of an unsold allotment from the original sales of
Old Notes) with this Prospectus.  Under the Registration  Rights Agreement,  the
Company is required to allow Participating Broker-Dealers (and other persons, if
any, subject to similar prospectus delivery requirements) to use this Prospectus
in connection with the resale of such New Notes, provided,  however, the Company
shall  not be  required  to amend or  supplement  such  prospectus  for a period
exceeding 120 days after the  effectiveness  of the Exchange Offer  Registration
Statement.

         If (a) the Company fails to consummate  the Exchange Offer on or before
the 45th day after the effective date of the Registration  Statement or 180 days
after the Issue Date or (b) either the Exchange Offer Registration  Statement or
the Shelf Registration  Statement is declared effective but thereafter ceases to
be  effective  in  connection  with resales of Old Notes or New Notes during the
period specified in the Registration  Rights Agreement (each such event referred
to in clauses (a) and (b) above a "Registration Default"), then the Company will
pay to each  holder of the Old Notes,  accruing  from the date of the first such
Registration  Default (or if such Registration  Default has been cured, from the
date  of  the  next  Registration  Default),   liquidated  damages  ("Liquidated
Damages") in an amount equal to 0.50% per annum of the  principal  amount of the
Old Notes held by such holder.  Following the cure of all Registration Defaults,
the accrual of Liquidated Damages will cease.

         If the Exchange Offer is consummated in accordance  with the provisions
of the Registration  Rights  Agreement  described above, the Company will not be
required to file a Shelf Registration  Statement to register any outstanding Old
Notes,  and the interest rate on such Old Notes will remain at its initial level
of 6 3/4% per annum. The Exchange Offer shall be deemed to have been consummated
upon the Company's having  exchanged,  pursuant to the Exchange Offer, New Notes
for all Old Notes that have been  properly  tendered  and not  withdrawn  by the
Expiration  Date. In such event,  holders of Old Notes not  participating in the
Exchange Offer who are seeking  liquidity in their investment would have to rely
on exemptions to registration  requirements under the securities laws, including
the Securities Act.

         Based on no-action  letters  issued by the staff of the  Commission  to
third parties,  the Company  believes that the New Notes issued  pursuant to the
Exchange  Offer in exchange for Old Notes may be offered for resale,  resold and
otherwise  transferred by holders thereof (other than any such holder that is an
"affiliate"  of the Company  within the meaning of Rule 405 under the Securities
Act)  without   compliance  with  the  registration   and  prospectus   delivery
requirements of the Securities Act, provided that such New Notes are acquired in
the  ordinary  course  of  such  holders'  business  and  such  holders  have no
arrangement  with any  person to  participate  in the  distribution  of such New
Notes. Any holder of Old Notes who tenders in the Exchange Offer for the purpose
of  participating  in a  distribution  of the  New  Notes  cannot  rely  on such
interpretation  by  the  staff  of the  Commission  and  must  comply  with  the
registration  and  prospectus  delivery  requirements  of the  Securities Act in
connection with any resale  transaction.  Each  broker-dealer  that receives New
Notes for its own account in exchange  for Old Notes,  where such Old Notes were
acquired by such broker-dealer as a result of market-making  activities or other
trading  activities,  must  acknowledge  that it will  deliver a  prospectus  in
connection with any resale of such New Notes.

Expiration Date; Extensions; Amendments

         The term "Expiration  Date" shall mean 5:00 p.m. New York City time, on
_________, 1998 unless the Company, in its sole discretion, extends the Exchange
Offer,  in which case the term  "Expiration  Date" shall mean the latest date to
which the Exchange Offer is extended.

         In order to extend the  Expiration  Date,  the Company  will notify the
Exchange  Agent of any extension by oral or written  notice and will mail to the
record holders of Old Notes an  announcement  thereof,  each prior to 9:00 a.m.,
New York City time,  on the next  business  day after the  previously  scheduled
Expiration  Date. Such  announcement may state that the Company is extending the
Exchange Offer for a specified period of time.

         The  Company  reserves  the  right (i) to delay  acceptance  of any Old
Notes,  to extend the Exchange  Offer or to terminate the Exchange  Offer and to
refuse to accept Old Notes not previously accepted, if any of the conditions set
forth herein  under  "Termination"  shall have  occurred and shall not have been
waived by the Company (if permitted to be waived by the Company), by giving oral
or written notice of such delay, extension or termination to the Exchange Agent,
and (ii) to amend the terms of the Exchange  Offer in any manner deemed by it to
be advantageous  to the holders of the Old Notes.  Any such delay in acceptance,
extension,  termination or amendment will be followed as promptly as practicable
by oral or written notice thereof. If the Exchange Offer is amended in

                                       10

<PAGE>



a manner determined by the Company to constitute a material change,  the Company
will  promptly  disclose  such  amendment in a manner  reasonably  calculated to
inform the holders of the Old Notes of such amendment.

         Without  limiting  the manner in which the  Company  may choose to make
public  announcements  of any delay in  acceptance,  extension,  termination  or
amendment  of the  Exchange  Offer,  the  Company  shall have no  obligation  to
publish, advertise, or otherwise communicate any such public announcement, other
than by making a timely release to the Dow Jones News Service.

Interest on the New Notes

         The New Notes will bear interest from the last Interest Payment Date on
which  interest was paid on the Old Notes,  or if interest has not yet been paid
on the Old Notes,  from  December 18, 1997.  Such interest will be paid with the
first interest payment on the New Notes.  Interest on the Old Notes accepted for
exchange will cease to accrue upon issuance of the New Notes.

         The  New  Notes  will  bear  interest  at a rate of 6 3/4%  per  annum.
Interest  on the New Notes  will be  payable  semi-annually,  in arrears on each
Interest  Payment  Date  following  the  consummation  of  the  Exchange  Offer.
Untendered  Old  Notes  that are not  exchanged  for New Notes  pursuant  to the
Exchange  Offer will  continue  to bear  interest  at a rate of 6 3/4% per annum
after the Expiration Date.

Procedures for Tendering

         To tender in the Exchange Offer, a holder must complete,  sign and date
the Letter of Transmittal,  or a facsimile thereof,  have the signatures thereon
guaranteed  if  required  by the Letter of  Transmittal,  and mail or  otherwise
deliver  such Letter of  Transmittal  or such  facsimile  or an Agent's  Message
(defined  below)  in lieu  thereof,  together  with the Old  Notes  (unless  the
book-entry transfer procedures  described below are used) and any other required
documents,  to the Exchange  Agent for receipt prior to 5:00 p.m., New York City
time, on the Expiration Date.

         The  term  "Agent's  Message"  means a  message,  transmitted  by DTC's
Book-Entry  Transfer Facility system to, and received by, the Exchange Agent and
forming a part of a Book-Entry Confirmation,  which states that DTC's Book-Entry
Transfer  Facility  system  has  received  an  express  acknowledgment  from the
participant in DTC's  Book-Entry  Transfer  Facility system  tendering Old Notes
which are the subject of such Book-Entry  Confirmation that such participant has
received and agrees to be bound by the terms of the Letter of  Transmittal,  and
that the Company may enforce such agreement against such  participant.  The term
"Book-Entry  Confirmation" means a timely confirmation of book-entry transfer of
Old Notes to the Exchange Agent's account at DTC's Book-Entry  Transfer Facility
system.

         Any financial  institution  that is a participant  in DTC's  Book-Entry
Transfer  Facility  system  may make  book-entry  delivery  of the Old  Notes by
causing  DTC to transfer  such Old Notes into the  Exchange  Agent's  account in
accordance  with DTC's  procedure for such  transfer.  Although  delivery of Old
Notes may be effected  through  book-entry  transfer  into the Exchange  Agent's
account at DTC, an Agent's  Message must be  transmitted  to and received by the
Exchange  Agent on or prior to the  Expiration  Date at one of its addresses set
forth in this Prospectus,  or the Letter of Transmittal (or facsimile  thereof),
with any required signature guarantees and any other required documents, must be
transmitted  to and received or confirmed by the Exchange Agent at its addresses
set forth in this  Prospectus  prior to 5:00 p.m.,  New York City  time,  on the
Expiration Date.  DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH ITS PROCEDURES
DOES NOT  CONSTITUTE  DELIVERY TO THE EXCHANGE  AGENT.  All  references  in this
Prospectus  to deposit or delivery of Old Notes shall be deemed to include DTC's
book-entry delivery method.

         The  tender by a holder  of Old  Notes  will  constitute  an  agreement
between such holder and the Company in accordance  with the terms and subject to
the conditions set forth herein and in the Letter of Transmittal.

         Delivery of all  documents  must be made to the  Exchange  Agent at its
address  set forth  herein.  Holders  may also  request  that  their  respective
brokers,  dealers,  commercial  banks,  trust  companies or nominees effect such
tender for such holders.

                                       11

<PAGE>



         The method of delivery of Old Notes and the Letter of  Transmittal  and
all other  required  documents to the Exchange Agent is at the election and risk
of the holders.  Instead of delivery by mail, it is recommended that holders use
an overnight or hand delivery service.  In all cases,  sufficient time should be
allowed to assure timely delivery.  No Letter of Transmittal or Old Notes should
be sent to the Company.

         Only a holder of Old Notes may  tender  such Old Notes in the  Exchange
Offer.  The term "holder" with respect to the Exchange Offer means any person in
whose  name Old Notes are  registered  on the books of the  Company or any other
person  who has  obtained a properly  completed  bond power from the  registered
holder or any  person  whose Old Notes are held of record by DTC who  desires to
deliver such Old Notes by book-entry transfer at DTC.

         Any beneficial holder whose Old Notes are registered in the name of his
broker,  dealer,  commercial bank, trust company or other nominee and who wishes
to tender  should  contact such  registered  holder  promptly and instruct  such
registered  holder to tender on his behalf.  If such beneficial holder wishes to
tender on his own behalf,  such beneficial  holder must, prior to completing and
executing the Letter of Transmittal  and  delivering his Old Notes,  either make
appropriate arrangements to register ownership of the Old Notes in such holder's
name or obtain a properly  completed bond power from the registered  holder. The
transfer of record ownership may take considerable time.

         Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be,  must be  guaranteed  by a  member  firm of a  registered  national
securities exchange or of the National Association of Securities Dealers,  Inc.,
a commercial  bank or trust  company  having an office or  correspondent  in the
United States or an "eligible guarantor  institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution") that is a participant
in a  recognized  medallion  signature  guarantee  program  unless the Old Notes
tendered  pursuant  thereto are tendered (i) by a registered  holder who has not
completed the box entitled "Special Issuance  Instructions" or "Special Delivery
Instructions"  on the  Letter  of  Transmittal  or (ii)  for the  account  of an
Eligible Institution.

         If the  Letter of  Transmittal  is signed  by a person  other  than the
registered  holder  of any Old Notes  listed  therein,  such Old  Notes  must be
endorsed or accompanied by appropriate  bond powers which  authorize such person
to  tender  the Old Notes on behalf of the  registered  holder,  in either  case
signed as the name of the registered holder or holders appears on the Old Notes.

         If the Letter of Transmittal or any Old Notes or bond powers are signed
by trustees, executors, administrators,  guardians, attorneys-in-fact,  officers
of corporations or others acting in a fiduciary or representative capacity, such
persons  should so indicate  when  signing,  and unless  waived by the  Company,
submit  evidence  satisfactory  to the Company of their authority to so act with
the Letter of Transmittal.

         All questions as to the validity,  form, eligibility (including time of
receipt), acceptance and withdrawal of the tendered Old Notes will be determined
by the Company in its sole  discretion,  which  determination  will be final and
binding. The Company reserves the absolute right to reject any and all Old Notes
not properly tendered or any Old Notes the Company's  acceptance of which would,
in the  opinion of counsel  for the  Company,  be  unlawful.  The  Company  also
reserves the absolute right to waive any  irregularities or conditions of tender
as to  particular  Old  Notes.  The  Company's  interpretation  of the terms and
conditions of the Exchange Offer  (including the  instructions  in the Letter of
Transmittal)  will be final and  binding  on all  parties.  Unless  waived,  any
defects or  irregularities in connection with tenders of Old Notes must be cured
within such time as the  Company  shall  determine.  Neither  the  Company,  the
Exchange Agent nor any other person shall be under any duty to give notification
of defects or irregularities  with respect to tenders of Old Notes nor shall any
of them incur any  liability for failure to give such  notification.  Tenders of
Old Notes will not be deemed to have been made until  such  irregularities  have
been cured or waived.  Any Old Notes received by the Exchange Agent that are not
properly  tendered and as to which the defects or  irregularities  have not been
cured or waived  will be  returned  without  cost by the  Exchange  Agent to the
tendering  holder of such Old Notes unless  otherwise  provided in the Letter of
Transmittal as soon as practicable following the Expiration Date.

         In addition,  the Company  reserves the right in its sole discretion to
(a) purchase or make offers for any Old Notes that remain outstanding subsequent
to the Expiration Date, or, as set forth under "Termination," to terminate

                                       12

<PAGE>



the Exchange Offer and (b) to the extent  permitted by applicable law,  purchase
Old Notes in the open market, in privately negotiated transactions or otherwise.
The terms of any such  purchases  or  offers  may  differ  from the terms of the
Exchange Offer.

Guaranteed Delivery Procedures

         Holders who wish to tender  their Old Notes and (i) whose Old Notes are
not  immediately  available,  or (ii) who cannot  deliver  their Old Notes,  the
Letter of  Transmittal  or any other  required  documents to the Exchange  Agent
prior to the  Expiration  Date, or if such holder cannot  complete the procedure
for book-entry transfer on a timely basis, may effect a tender if:

                  (a)  the tender is made through an Eligible Institution;

                  (b) prior to the Expiration  Date, the Exchange Agent receives
         from such Eligible  Institution a properly  completed and duly executed
         Notice of Guaranteed Delivery (by facsimile transmission,  mail or hand
         delivery)  setting  forth the name and address of the holder of the Old
         Notes,  the  certificate  number or  numbers  of such Old Notes and the
         principal  amount of Old Notes  tendered,  stating  that the  tender is
         being made thereby,  and guaranteeing  that, within three business days
         after the  Expiration  Date,  the Letter of  Transmittal  (or facsimile
         thereof),  together with the certificate(s)  representing the Old Notes
         (unless  the  book-entry  transfer  procedures  are to be  used)  to be
         tendered in proper form for transfer and any other  documents  required
         by the  Letter  of  Transmittal,  will  be  deposited  by the  Eligible
         Institution with the Exchange Agent; and

                  (c) such properly completed and executed Letter of Transmittal
         (or facsimile thereof),  together with the certificate(s)  representing
         all tendered Old Notes in proper form for transfer (or  confirmation of
         a book-entry  transfer into the Exchange  Agent's account at DTC of Old
         Notes delivered electronically) and all other documents required by the
         Letter of  Transmittal  are received by the Exchange Agent within three
         business days after the Expiration Date.

         Upon request to the Exchange  Agent,  a Notice of  Guaranteed  Delivery
will be sent to  holders  who wish to tender  their Old Notes  according  to the
guaranteed delivery procedures set forth above.

Withdrawal of Tenders

         Except  as  otherwise  provided  herein,  tenders  of Old  Notes may be
withdrawn at any time prior to 5:00 p.m.,  New York City time, on the Expiration
Date.

         To withdraw a tender of Old Notes in the Exchange  Offer,  a written or
facsimile  transmission  notice of  withdrawal  must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration  Date. Any such notice of withdrawal must (i) specify the name of
the person  having  deposited the Old Notes to be withdrawn  (the  "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number or
numbers  and  principal  amount  of such  Old  Notes),  (iii) be  signed  by the
Depositor  in the  same  manner  as the  original  signature  on the  Letter  of
Transmittal  by which  such Old Notes  were  tendered  (including  any  required
signature  guarantees) or be accompanied by documents of transfer  sufficient to
permit the Trustee  with  respect to the Old Notes to register  the  transfer of
such Old Notes into the name of the  Depositor  withdrawing  the tender and (iv)
specify the name in which any such Old Notes are to be registered,  if different
from  that  of the  Depositor.  All  questions  as to  the  validity,  form  and
eligibility  (including  time of receipt)  of such  withdrawal  notices  will be
determined by the Company, whose determination shall be final and binding on all
parties.  Any Old Notes so  withdrawn  will be deemed  not to have been  validly
tendered  for purposes of the  Exchange  Offer,  and no New Notes will be issued
with respect  thereto unless the Old Notes so withdrawn are validly  retendered.
Any Old Notes that have been  tendered  but which are not  accepted for exchange
will be returned to the holder  thereof  without  cost to such holder as soon as
practicable after withdrawal, rejection of tender or termination of the Exchange
Offer.  Properly  withdrawn  Old Notes may be retendered by following one of the
procedures described above under "Procedures for Tendering" at any time prior to
the Expiration Date.

Termination

         Notwithstanding  any other term of the Exchange Offer, the Company will
not be required to accept for exchange,  or exchange New Notes for any Old Notes
not theretofore  accepted for exchange,  and may terminate or amend the Exchange
Offer as provided  herein  before the  acceptance  of such Old Notes if: (i) any
action or  proceeding  is  instituted or threatened in any court or by or before
any  governmental  agency with  respect to the  Exchange  Offer,  which,  in the
Company's  judgment,  might materially  impair the Company's  ability to proceed
with  the  Exchange  Offer  or (ii)  any law,  statute,  rule or  regulation  is
proposed,  adopted or enacted, or any existing law, statute,  rule or regulation
is  interpreted  by the  staff of the  Commission  in a  manner,  which,  in the
Company's  judgment,  might materially  impair the Company's  ability to proceed
with the Exchange Offer.

         If the Company  determines that it may terminate the Exchange Offer, as
set forth  above,  the Company may (i) refuse to accept any Old Notes and return
any Old Notes that have been  tendered to the holders  thereof,  (ii) extend the
Exchange  Offer and retain all Old Notes tendered prior to the expiration of the
Exchange  Offer,  subject to the rights of such holders of tendered Old Notes to
withdraw their tendered Old Notes,  or (iii) waive such  termination  event with
respect to the Exchange  Offer and accept all  properly  tendered Old Notes that
have not been  withdrawn.  If such waiver  constitutes a material  change in the
Exchange  Offer,  the Company will disclose such change by means of a supplement
to this  Prospectus  that will be distributed to each  registered  holder of Old
Notes,  and the Company will extend the  Exchange  Offer for a period of five to
ten business days,  depending upon the significance of the waiver and the manner
of disclosure to the registered  holders of the Old Notes, if the Exchange Offer
would otherwise expire during such period.

Fees and Expenses

         The expenses of soliciting  tenders pursuant to the Exchange Offer will
be borne by the Company. The principal  solicitation for tenders pursuant to the
Exchange Offer is being made by mail.  Additional  solicitations  may be made by
officers and regular  employees of the Company and its affiliates in person,  by
telegraph or by telephone.

         The Company  will not make any  payments  to brokers,  dealers or other
persons soliciting acceptances of the Exchange Offer. The Company, however, will
pay the Exchange  Agent  reasonable and customary fees for its services and will
reimburse  the  Exchange  Agent for its  reasonable  out-of-pocket  expenses  in
connection  therewith.  The  Company  may also pay  brokerage  houses  and other
custodians,  nominees and  fiduciaries  the  reasonable  out-of-pocket  expenses
incurred by them in forwarding copies of this Prospectus, Letters of Transmittal
and related  documents to the beneficial owners of the Old Notes and in handling
or forwarding tenders for exchange.

         The  expenses to be incurred in  connection  with the  Exchange  Offer,
including fees and expenses of the Exchange Agent and Trustee and accounting and
legal fees, will be paid by the Company.

                                       14

<PAGE>



         The Company  will pay all transfer  taxes,  if any,  applicable  to the
exchange of Old Notes pursuant to the Exchange Offer. If, however,  certificates
representing New Notes or Old Notes not tendered or accepted for exchange are to
be delivered  to, or are to be  registered  or issued in the name of, any person
other than the registered  holder of the Old Notes tendered,  or if tendered Old
Notes are registered in the name of any person other than the person signing the
Letter of Transmittal, or if a transfer tax is imposed for any reason other than
the exchange of Old Notes pursuant to the Exchange Offer, then the amount of any
such  transfer  taxes  (whether  imposed on the  registered  holder or any other
persons) will be payable by the tendering  holder.  If satisfactory  evidence of
payment of such taxes or exemption therefrom is not submitted with the Letter of
Transmittal,  the amount of such transfer taxes will be billed  directly to such
tendering holder.

Accounting Treatment

         The New Notes will be  recorded at the same  carrying  value as the Old
Notes, which is face value, as reflected in the Company's  accounting records on
the date of the exchange.  Accordingly,  no gain or loss for accounting purposes
will be recognized by the Company upon the  consummation  of the Exchange Offer.
The  expenses of the  Exchange  Offer will be  amortized by the Company over the
term of the New Notes under generally accepted accounting principles.


                          DESCRIPTION OF THE NEW NOTES

         The New Notes are to be issued  under an Indenture  and a  Supplemental
Indenture,  each dated as of December 18, 1997 (collectively,  the "Indenture"),
between the Company and State Street Bank and Trust Company (the "Trustee"). The
terms of the New Notes  include  those stated in the  Indenture and those made a
part of the  Indenture  by  reference  to the Trust  Indenture  Act of 1939 (the
"Trust Indenture Act"). The New Notes are subject to all such terms, and holders
of the Old Notes and the New Notes are referred to the  Indenture  and the Trust
Indenture  Act for a statement  thereof.  The  Indenture has been filed with the
Commission  and  is  incorporated  by  reference  herein  and is  available  for
inspection  at the  corporate  trust office of the Trustee at Two  International
Place,  Boston,  Massachusetts  02110. The statements made hereunder relating to
the Indenture and the New Notes to be issued thereunder are summaries of certain
provisions  thereof,  do not purport to be complete  and are subject to, and are
qualified in their entirety by reference to, all provisions of the Indenture and
such New Notes. All section  references  appearing herein are to sections of the
Indenture,  and  capitalized  terms used but not defined  herein  shall have the
respective meanings set forth in the Indenture.

General

         The New Notes  will be  limited  to an  aggregate  principal  amount of
$150,000,000 and will mature,  unless previously redeemed, on December 18, 2002.
The New  Notes  will be issued  in  registered  form,  without  coupons,  and in
denominations  of $100,000 and integral  multiples of $1,000 in excess  thereof.
The New Notes will be senior unsecured  obligations of the Company and will rank
equally  with  each  other  and  with all  other  unsecured  and  unsubordinated
indebtedness of the Company from time to time outstanding. The New Notes will be
effectively  subordinated  to mortgages  and other secured  indebtedness  of the
Company  and to  indebtedness  and other  liabilities  of any  Subsidiaries  (as
defined below).  Accordingly,  such prior indebtedness will have to be satisfied
in full  before  holders of the New Notes will be able to realize any value from
the secured or indirectly held properties.

         As of March 1, 1998, the total outstanding  indebtedness of the Company
and its Subsidiaries  (including net borrowings made for acquisitions during the
period of October 1, 1997 through March 1, 1998 under the Bank Credit  Facility)
was approximately $758 million,  of which  approximately 97% was unsecured,  and
the indebtedness of the Company's Subsidiaries was $26 million. In addition, the
Company's Subsidiaries (with certain exceptions) are guarantors of the Company's
Bank  Credit  Facility.  The Bank  Credit  Facility is  currently  an  unsecured
revolving  credit  facility in the amount of $450  million.  The Company and its
Subsidiaries may incur additional indebtedness,  including secured indebtedness,
subject    to    the    provisions     described    below    under    "--Certain
Covenants--Limitations on Incurrence of Debt."

                                       15
<PAGE>
         Except  as  described  under  "--Merger,  Consolidation  or  Sale"  and
"--Certain Covenants" below, the Indenture does not contain any other provisions
that would limit the ability of the Company to incur  indebtedness or that would
afford  holders  of the  New  Notes  protection  in the  event  of (i) a  highly
leveraged or similar  transaction  involving the Company or any affiliate of the
Company,  (ii) a change of control,  or (iii) a  reorganization,  restructuring,
merger or similar  transaction  involving the Company that may adversely  affect
the holders of the New Notes. In addition,  subject to the limitations set forth
under  "--Merger,  Consolidation or Sale" and "--Certain  Covenants"  below, the
Company may, in the future,  enter into certain transactions such as the sale of
all or  substantially  all of its assets or the merger or  consolidation  of the
Company  that  would  increase  the  amount  of the  Company's  indebtedness  or
substantially  reduce  or  eliminate  the  Company's  assets,  which may have an
adverse effect on the Company's ability to service its  indebtedness,  including
the New Notes.  The  Company and its  management  have no present  intention  of
engaging in a highly leveraged or similar transaction involving the Company.

Interest

         Interest  on the New Notes will accrue at the rate of 6 3/4% per annum.
Interest  on the New Notes will be payable  semi-annually  in arrears on June 18
and December 18 commencing on June 18, 1998 (each, an "Interest  Payment Date"),
and on the date of maturity or earlier  redemption of the New Notes, as the case
may be (the "Maturity Date"). The interest so payable will be paid to the person
(the  "Holder") in whose name the applicable New Note is registered at the close
of  business  on the date  (whether  or not a  Business  Day) 15  calendar  days
preceding the  applicable  Interest  Payment Date or the Maturity Date (each,  a
"Regular  Record  Date").  Interest  on the New Notes will  accrue from the most
recent  date to which the  interest  has been paid or, if no  interest  has been
paid, from the date of original issuance. Interest will be computed on the basis
of a 360-day  year  comprised  of twelve  30-day  months.  The New Notes will be
payable both as to principal and interest at the  corporate  trust office of the
Trustee, initially at Two International Place, Boston,  Massachusetts 02110, or,
at the option of the Company, payment of interest may be made by check mailed to
the Holders of New Notes at their addresses set forth in the register of Holders
of New Notes.

Optional Redemption of New Notes

         Until the third  month prior to their  stated  Maturity  Date,  the New
Notes will be subject to redemption at any time at the option of the Company, in
whole or in part,  upon not less than 30 nor more than 60 days' notice,  at 100%
of the outstanding principal amount thereof, plus accrued and unpaid interest to
but excluding the applicable redemption date, plus the Make-Whole Amount. On and
after the third month prior to the stated  Maturity Date for the New Notes,  the
New  Notes  will be  subject  to  redemption  at any time at the  option  of the
Company,  in  whole or in part,  upon  not less  than 30 nor more  than 60 days'
notice,  at 100% of the outstanding  principal amount thereof,  plus accrued and
unpaid interest to but excluding the applicable redemption date.

         The Company is not required to make sinking fund or redemption payments
with respect to the New Notes.

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

         "Reinvestment  Rate" means 0.25%  (twenty-five  one  hundredths  of one
percent) plus the yield on treasury  securities at constant  maturity  under the
heading "Week  Ending"  published in the  Statistical  Release under the caption
"Treasury  Constant  Maturities" for the maturity (rounded to the nearest month)
corresponding  to the remaining life to maturity,  as of the payment date of the
principal  being  redeemed or paid. If no maturity  exactly  corresponds to such
maturity,  yields for the two published maturities most closely corresponding to
such maturity
                                       16
<PAGE>

shall be  calculated  pursuant to the  immediately  preceding  sentence  and the
Reinvestment  Rate shall be interpolated  or extrapolated  from such yields on a
straight-line  basis,  rounding in each of such relevant  periods to the nearest
month.  For  purposes of  calculating  the  Reinvestment  Rate,  the most recent
Statistical  Release  published  prior  to  the  date  of  determination  of the
Make-Whole Amount shall be used.

         "Statistical  Release"  means the  statistical  release  designated "H.
15(519)" or any successor  publication  which is published weekly by the Federal
Reserve  System and which  establishes  yields on actively  traded United States
government  securities  adjusted to constant  maturities or, if such statistical
release is not published at the time of any  determination  under the Indenture,
then any  publicly  available  source of  similar  market  data  which  shall be
designated by the Company.

Certain Covenants

         Existence. Except as permitted under "--Merger,  Consolidation or Sale"
below,  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 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 so required to file 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 the New
Notes, as their names and addresses appear in the Company's  register of holders
of New Notes,  without  cost to the  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  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 the New Notes.

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

         In addition to the foregoing limitations on the incurrence of Debt, the
Company will not, and will not permit any  Subsidiary to, incur any Secured Debt
(as defined below) if, immediately after giving effect to the incurrence of such
additional  Secured  Debt  and the  application  of the  proceeds  thereof,  the
aggregate  principal  amount of all outstanding  Secured Debt of the Company and
its  Subsidiaries on a consolidated  basis is greater than 40% of Adjusted Total
Assets.
                                       17
<PAGE>
         In addition to the foregoing limitations on the Incurrence of Debt, the
Company will not, and will not permit any  Subsidiary  to, incur any Debt if the
ratio of  Consolidated  Income  Available for Debt Service (as defined below) to
the Annual  Debt  Service  (as defined  below) for the four  consecutive  fiscal
quarters most recently ended prior to the date on which such  additional Debt is
to be incurred shall have been less than 1.5x, on a pro forma basis after giving
effect thereto and to the application of the proceeds therefrom,  and calculated
on the assumption  that (i) such Debt and any other Debt incurred by the Company
and its  Subsidiaries  since the first day of such  four-quarter  period and the
application of the proceeds  therefrom,  including to refinance  other Debt, had
occurred at the  beginning of such period;  (ii) the  repayment or retirement of
any other Debt by the Company and its Subsidiaries  since the first date of such
four-quarter  period had been repaid or retired at the  beginning of such period
(except  that, in making such  computation,  the amount of Debt repaid under any
revolving credit facility shall be computed based upon the average daily balance
of such Debt during such period); (iii) in the case of Acquired Debt (as defined
below) or Debt incurred in connection with any  acquisition  since the first day
of such  four-quarter  period,  the related  acquisition  had occurred as of the
first day of such  period  with  appropriate  adjustments  with  respect to such
acquisition being included in such pro forma  calculation;  and (iv) in the case
of any  acquisition  or disposition  by the Company or its  Subsidiaries  of any
asset or group of  assets  since  the  first  day of such  four-quarter  period,
whether by merger,  stock  purchase or sale,  or asset  purchase  or sale,  such
acquisition or  disposition or any related  repayment of Debt had occurred as of
the first day of such period with the  appropriate  adjustments  with respect to
such acquisition or disposition being included in such as adjusted calculation.

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

on the Company's  consolidated  balance sheet in accordance  with GAAP, and also

now exists or shall  hereafter be incurred or created,  which default shall have
resulted in such  indebtedness  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  written  notice to the
Company by the  Trustee or to the  Company  and the Trustee by the Holders of at
least 25% in principal  amount of the  outstanding New Notes, as provided in the
Indenture; or (v) certain events of bankruptcy, insolvency or reorganization, or
court  appointment  of a receiver,  liquidator  or trustee of the Company or any
Significant  Subsidiary  or  for  all or  substantially  all  of  either  of its
property.  "Significant Subsidiary" means any Subsidiary which is a "significant
subsidiary"  (within  the  meaning  of  Regulation  S-X,  promulgated  under the
Securities Act) of the Company.

         See "Description of  Indenture--Events  of Default,  Notice and Waiver"
below for a description of rights, remedies and other matters relating to Events
of Default.

Discharge, Defeasance and Covenant Defeasance

         The  provisions  of the Indenture  relating to defeasance  and covenant
defeasance described under "Description of Indenture--Discharge,  Defeasance and
Covenant Defeasance" below will apply to the New Notes.

Book-Entry System

         Old Notes were represented  initially by a permanent global certificate
in fully  registered form without  interest coupons (the "Global Note") and were
registered  in the  name of a  nominee  of DTC  and  deposited  with  DTC or its
custodian.  The Global Note was  subject to certain  restrictions  on  transfer.
Beneficial interests in the Global Note may be transferred to a person who takes
delivery  in the form of an  interest in a single  global  certificate  in fully
registered form without interest coupons,  whether before, on or after such 40th
day,  only upon  receipt  by the  Trustee  of a written  certification  from the
transferor  to the effect that such  transfer is being made in  accordance  with
Rule  903 or 904 of  Regulation  S or Rule  144  under  the  Securities  Act (an
"Unrestricted Global Note Certification"). Any beneficial interest in one of the
global notes that is  transferred  to a person who takes delivery in the form of
an  interest  in the other  global  note  will,  upon  transfer,  cease to be an
interest in such  global  note and will  become an interest in the other  global
note and,  accordingly,  will thereafter be subject to all transfer restrictions
and other procedures and restrictions applicable to beneficial interests in such
other global note for as long as it remains such an interest.

         The Global Note, to the extent directed by the holders thereof in their
Letters of Transmittal, will be exchanged through book-entry electronic transfer
for a Global Note (the "New Global  Note") in definitive  fully-


                                       20
<PAGE>

registered form without interest coupons  registered in the name of a nominee of
DTC and held by the Trustee as  custodian.  Except in the limited  circumstances
described below, owners of beneficial  interests in the New Global Note will not
be entitled to receive physical delivery of Notes.

         Upon the issuance of the New Global  Note,  DTC or its  custodian  will
credit,  in  its  internal  system,  the  respective  principal  amount  of  the
individual  beneficial  interests  represented  by the  New  Global  Note to the
accounts of persons who have accounts with DTC. Ownership of beneficial interest
in the New Global  Note will be limited to persons  who have  accounts  with DTC
("DTC  Participants")  or persons who hold interests  through DTC  Participants.
Ownership of  beneficial  interests in the New Global Note will be shown on, and
the transfer of that ownership will be effected only through, records maintained
by DTC or its nominee  (with respect to interests of DTC  Participants)  and the
records of DTC Participants (with respect to interests of persons other than DTC
Participants).

         Investors  may hold  their  interests  in the New Global  Note  through
Morgan Guaranty Trust Company of New York,  Brussels Office,  as operator of the
Euroclear System  ("Euroclear") or Citibank,  N.A., as depositary for Cedel S.A.
("Cedel"),  if they are  participants  in such systems,  or  indirectly  through
organizations  that are  participants  in such systems.  Investors may also hold
such  interests  through  organizations  other than Euroclear and Cedel that are
participants  in the DTC system.  Euroclear and Cedel will hold interests in the
New Global Note on behalf of their account holders through customers' securities
accounts  in  their   respective   names  on  the  books  of  their   respective
depositaries,  which in turn will hold such  interests in the New Global Note in
customers'  securities  accounts in the depositaries' names on the books of DTC.
Investors may also hold their interests in the New Global Note directly  through
DTC, if they are DTC Participants, or indirectly through organizations which are
DTC Participants.

         Payments of the  principal  of and interest on the New Global Note will
be made to DTC or its nominee as the registered owner thereof.  The Company will
not have any  responsibility or liability for any aspect of the records relating
to or payments  made on account of  beneficial  ownership  interests  in the New
Global Note or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

         The  Company  expects  that DTC or its  nominee,  upon  receipt  of any
payment of principal or interest in respect of the New Global Note  representing
any New Notes held by it or its nominee, will credit DTC Participants'  accounts
with payments in amounts  proportionate to their respective beneficial interests
in the principal amount of the New Global Note as shown on the records of DTC or
its  nominee.  The Company also expects  that  payments by DTC  Participants  to
owners of  beneficial  interests  in the New Global Note held  through  such DTC
Participants will be governed by standing  instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the  names  of  nominees  for  such  customers.  Such  payments  will  be the
responsibility of such DTC Participants.

         If DTC is at any time  unwilling or unable to continue as depositary or
is ineligible to act as depositary  and a successor  depositary is not appointed
by the  Company  within 90 days after the  Company is notified by DTC or becomes
aware of such condition,  the Company will issue New Notes in definitive form in
exchange for the New Global Note representing the New Notes.

         Individual  definitive  New Notes will not be eligible for clearing and
settlement through Euroclear, Cedel or DTC.

Same-Day Settlement and Payment

         All payments of principal and interest in respect of the New Notes will
be made by the Company in immediately available funds.

                            DESCRIPTION OF INDENTURE

         The  New  Notes  will  be  issued  pursuant  to the  Indenture  and the
supplement relating thereto,  which was entered into between the Company and the
Trustee.  The  Indenture  provides for the  issuance of multiple  series of debt
securities,  including the New Notes (each "Debt Securities") in accordance with
the terms thereof and the applicable supplemental indenture. The statements made
hereunder  relating  to the  Indenture  and the  Debt  Securities  to be  issued
thereunder  are  summaries and do not purport to be complete and are subject to,
and are  qualified in their  entirety by  reference  to, all  provisions  of the
Indenture and such Debt  Securities.  Terms of the  supplemental  indenture with
respect  to  the  New  Notes,   certain  of  which  are  described  above  under
"Description  of  the  New  Notes,"  supersede  conflicting  provisions  of  the
Indenture  described  below,  insofar  as  applicable  to  the  New  Notes.  The
description  of certain  provisions  of the Indenture  described  below does not
purport to be complete,  and reference is made to the  definitive  Indenture and
the  supplemental  indenture  relating  to the New  Notes,  copies  of which are
available upon request from the Company.

General

         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 or as established in one or more indentures supplemental
to the  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 Trustee  thereunder,  each with respect to
one or more series of Debt  Securities.  Any  Trustee  under the  Indenture  may
resign or be removed with respect to one or more series of Debt Securities,  and
a successor  Trustee may be appointed to act with respect to such series. In the
event that two or more  persons are acting as Trustee  with respect to different
series of Debt Securities, each such Trustee shall be a trustee of a trust under
the  Indenture  separate  and  apart  from the trust  administered  by any other
Trustee,  and, except as otherwise indicated herein, any action described herein
to be taken by the Trustee may be taken by each such  Trustee  with  respect to,
and only with respect to, the one or more series of Debt Securities for which it
is Trustee under the Indenture.

         Except  as  described  under  "Description  of the  New  Notes--Certain
Covenants" and  "Description of New  Notes--Merger,  Consolidation or Sale," and
"The Exchange  Offer," the Indenture does not contain any other  provisions that
limit the ability of the Company to incur indebtedness or that 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.

Denominations, Interest, Registration and Transfer

         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
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 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  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 Trustee.
Every Debt Security surrendered for conversion, registration of transfer or

                                       22
<PAGE>
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  Trustee or the  Company may require
payment  of a sum  sufficient  to  cover  any tax or other  governmental  charge
payable  in  connection  therewith.  The  Company  may at any time  rescind  the
designation of any transfer agent  designated by the Company with respect to any
series of Debt Securities 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  transfer  agents in addition to the Trustee with respect to any
series of Debt Securities.

         Neither the  Company  nor the  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.

Events of Default, Notice and Waiver

         The  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
Indenture  (other than a covenant added to the 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 the
Indenture; (e) default in the payment of an aggregate principal amount exceeding
$20,000,000  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 the  Indenture  with respect to Debt  Securities  of any
series at the time outstanding occurs and is continuing, then in every such case
the 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 Debt Securities that provide for
less than the entire  principal amount thereof to be payable upon declaration of
acceleration of the maturity thereof (an "Original Issue Discount  Security") 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 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 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

                                       23
<PAGE>
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  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 Indenture,  as
the case may be) may rescind and annul such  declaration and its consequences if
(i) the Company shall have deposited  with the 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 Indenture,  as
the case may be), plus certain fees, expenses, disbursements and advances of the
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 Indenture,  as the case may be) have been cured or waived
as provided in the  Indenture.  The Indenture 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
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 Indenture
that  cannot be  modified  or amended  without the consent of the holder of each
outstanding Debt Security affected thereby.

         The  Trustee  will be  required  to give  notice to the holders of Debt
Securities  within 90 days of a default under the Indenture  unless such default
has been cured or waived;  provided,  however,  that the  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  the  Trustee  consider  such
withholding to be in the interest of such holders.

         The  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
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 Indenture  relating to its duties in case
of default,  the Trustee will not be under any obligation to exercise any of its
rights or powers under the  Indenture at the request or direction of any holders
of any series of Debt Securities then  outstanding  under the Indenture,  unless
such holders shall have offered to the 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  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
Trustee,  or of  exercising  any  trust or  power  conferred  upon the  Trustee.
However,  the  Trustee may refuse to follow any  direction  which is in conflict
with any law or the  Indenture,  which  may  involve  the  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 the  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  Indenture
and, if so, specifying each such default and the nature and status thereof.

Modification of the Indenture

         Modifications  and  amendments of the 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
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

                                       24
<PAGE>
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 the  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.

         The 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 the Indenture.

         Modifications  and  amendments of the Indenture will be permitted to be
made by the Company and the 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 the 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 the 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  Trustee or
facilitate the administration of the trusts under the Indenture by more than one
Trustee;  (ix) to cure any ambiguity,  defect or inconsistency in the 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 the  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.

         The 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
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.

         The Indenture  will contain  provisions  for convening  meetings of the
holders of Debt  Securities of a series.  A meeting may be called at any time by
the 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 the  Indenture.  Except for any
consent  that  must be given by the  holder of each Debt  Security  affected  by
certain modifications and amendments of the 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

                                       25
<PAGE>
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 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,  the 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 the 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  the
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 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 the 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.

         The 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  the  Indenture   (including  the   restrictions   described  under
"Description of the New Notes--Certain  Covenants") and, if provided pursuant to
the  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 irrevocable  deposit by the Company with the 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 Trustee an opinion of counsel (as specified in the
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

                                       26
<PAGE>
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  supplement  indenture for
any series of Debt Securities  (other than the New Notes),  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 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 supplemental indenture
for any series of Debt  Securities  (other than the New Notes),  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"
above with respect to certain sections of the Indenture (which sections would no
longer be applicable to such Debt  Securities)  or described in clause (g) under
"--Events 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.

         The applicable supplemental indenture for any series of Debt Securities
(other  than  the New  Notes)  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.

                    CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

         The following  summary,  which  describes  the principal  United States
Federal income tax consequences resulting from the exchange of Old Notes for New
Notes and the  ownership  and  disposition  of New  Notes,  is based  upon laws,
regulations,  rulings and decisions  now in effect,  all of which are subject to
change   (including   changes  in   effective   dates)  or  possible   differing
interpretations.  The following discussion deals only with Notes held as capital
assets and does not purport to deal with persons in special tax situations, such
as financial  institutions,  banks,  insurance  companies,  regulated investment
companies, dealers in securities or currencies, persons holding Notes as a hedge
against  currency  risks or as a position in a "straddle"  for tax purposes,  or
persons whose functional  currency is not the United States dollar. It also does
not deal with  holders of the Notes other than  original  purchasers  of the Old
Notes.  Persons  considering  owning  the  Notes  should  consult  their own tax
advisors  concerning the application of United States Federal income tax laws to
their  particular  situations  as  well  as any  consequences  of the  purchase,
ownership  and  disposition  of the  Notes  arising  under the laws of any other
taxing jurisdiction.

         As used herein,  the term "U.S.  Holder" means a beneficial  owner of a
Note that is for United  States  Federal  income tax  purposes  (i) a citizen or
resident of the United  States,  (ii) a  corporation  or  partnership  (or other
entity treated as a corporation or partnership  for United States Federal income
tax purposes)  created or organized in or under the laws of the United States or
of any political  subdivision  thereof  (unless  otherwise  provided by Treasury
Regulations),  (iii) an estate the  income of which is subject to United  States
Federal income taxation regardless of its source, (iv) a trust if a court within
the  United   States  is  able  to  exercise   primary   supervision   over  the
administration  of the  trust and one or more  United  States  persons  have the
authority to control all substantial decisions of the trust (or certain electing
trusts in  existence  on August 20,  1996 to the  extent  provided  in  Treasury
Regulations),  or (v) any other person whose income or gain in respect of a Note
is effectively  connected with the conduct of a United States trade or business.
As used herein,  the term "non-U.S.  Holder" means a beneficial  owner of a Note
that is not a U.S. Holder.

         EACH HOLDER IS STRONGLY URGED TO CONSULT ITS TAX ADVISERS REGARDING THE
FEDERAL,  STATE,  LOCAL AND FOREIGN TAX CONSEQUENCES OF EXCHANGING OLD NOTES FOR
NEW NOTES AND HOLDING AND DISPOSING OF THE NEW NOTES.

Exchange Offer

         An exchange of Old Notes for New Notes  pursuant to the Exchange  Offer
should be regarded for Federal income tax purposes as a nontaxable  continuation
of the Old Notes,  and a holder should have the same adjusted  basis and holding
period  in the New Notes  upon  receipt  as it had in the Old Notes  immediately
before the exchange.

The Notes

         For U.S.  Federal  income  tax  purposes,  each Note will be treated as
indebtedness issued by the Company.

U.S. Holders

         Interest.  Interest on a Note will generally be includible in the gross
income of a U.S. Holder as ordinary  interest income at the time the interest is
received or when it accrues in accordance with the U.S.  Holder's regular method
of tax accounting.  Such interest will be treated as U.S. source income for U.S.
Federal income tax purposes.

         Disposition.  A U.S. Holder will recognize  taxable gain or loss on the
sale,  exchange,  redemption,  retirement or other  disposition  of a Note in an
amount equal to the difference between the amount realized from such disposition
(other than amounts  attributable  to accrued  interest which would otherwise be
taxable as ordinary interest income) and the U.S. Holder's adjusted tax basis in
the Note.  Such gain or loss generally will be capital gain or loss, and will be
long-term  capital  gain or loss if the U.S.  Holder  has held the Note for more
than one year at the time of disposition; preferential rates of tax may apply to
gains recognized by noncorporate U.S. Holders upon the disposition of Notes held
for more than eighteen months.

                                       28

<PAGE>
         Gain or Income Received by a Foreign Corporation. A foreign corporation
whose  income or gain in respect  of a Note is  effectively  connected  with the
conduct of a United  States trade or business,  in addition to being  subject to
regular U.S. Federal income tax, may be subject to a branch profits tax equal to
30% of its  "effectively  connected  earnings and profits" within the meaning of
the Internal  Revenue Code of 1986,  as amended  (the  "Code"),  for the taxable
year, as adjusted for certain items,  unless it qualifies for a lower rate under
an applicable tax treaty (as modified by the branch profits tax rules).

Non-U.S. Holders

         Generally,  a non-U.S.  Holder  will not be  subject  to United  States
Federal income taxes on payments of principal, premium, if any, or interest on a
Note,  or on any gain upon  disposition  or  retirement  of a Note,  if (i) such
non-U.S. Holder does not own 10% or more of the shares of beneficial interest of
the Company and (ii) the last United  States  payor in the chain of payment (the
"Withholding  Agent") has received in the year in which a payment of interest or
principal occurs, or in either of the two preceding  calendar years, a statement
signed by the beneficial owner of the Note under penalties of perjury certifying
that such owner is not a U.S.  Holder and  providing the name and address of the
beneficial  owner.  The  statement  may be made on an Internal  Revenue  Service
("IRS") Form W-8 or a substantially  similar form, and the beneficial owner must
inform the  Withholding  Agent of any change in the information on the statement
within 30 days of such change.  If a Note is held through a securities  clearing
organization  or certain  other  financial  institutions,  the  organization  or
institution may provide a signed statement to the Withholding Agent. However, in
such case,  the signed  statement  must be accompanied by a copy of the IRS Form
W-8 or the substitute form provided by the beneficial  owner to the organization
or institution.  Interest received or gain recognized by a non-U.S. Holder which
does not qualify for  exemption  from  taxation will be subject to United States
Federal  income  tax and  withholding  tax at a rate of 30%  unless  reduced  or
eliminated by applicable tax treaty.

         Treasury  Regulations issued on October 6, 1997 (the "New Regulations")
alter the withholding rules on interest paid to a non-U.S. Holder of a Note. The
New  Regulations  are  generally  effective  with respect to interest paid after
December  31,  1998.  Withholding  will  generally  be  excused  under  the  New
Regulations  if the  non-U.S.  Holder  owns  less  than  10% of  the  shares  of
beneficial  interest  of the  Company  and if such  non-U.S.  Holder  executes a
necessary IRS Form W-8. Moreover, under the New Regulations, to obtain a reduced
rate of withholding under an income tax treaty, a non-U.S. Holder generally will
be  required  to  provide  an IRS Form W-8  certifying  such  non-U.S.  Holder's
entitlement  to benefits  under the treaty.  The New  Regulations  also  provide
special  rules  to  determine   whether,   for  purposes  of   determining   the
applicability  of a tax treaty,  interest  paid to a non-U.S.  Holder that is an
entity should be treated as paid to the entity or to those holding the ownership
interests in that entity,  and whether such entity or such holders in the entity
are entitled to benefits under the tax treaty.  The New  Regulations  also alter
the information  reporting and backup  withholding  rules applicable to non-U.S.
Holders and,  among other things,  provide  certain  presumptions  under which a
non-U.S. Holder is subject to backup withholding and information reporting until
certification  of non-U.S.  status is received  from such non-U.S.  Holder.  The
foregoing is not intended to be a complete  discussion  of the New  Regulations,
and non-U.S. Holders are urged to consult their tax advisors with respect to the
effect of the New Regulations on an investment in the Notes.

         The Notes will not be includible in the estate of a non-U.S. Holder for
United  States  estate tax  purposes  unless the  individual  owns  directly  or
indirectly  10% or more of the shares of beneficial  interest of the Company or,
at the time of such individual's  death,  payments in respect of the Notes would
have been  effectively  connected with the conduct by such individual of a trade
or business in the United States.

Backup Withholding

         Backup withholding of United States Federal income tax at a rate of 31%
may apply to payments made in respect of the Notes to registered  owners who are
not "exempt recipients" and who fail to provide certain identifying  information
(such as the registered owner's taxpayer  identification number) in the required
manner. Generally,  individuals are not exempt recipients,  whereas corporations
and certain other  entities  generally are exempt  recipients.  Payments made in
respect of the Notes to a U.S.  Holder must be  reported to the IRS,  unless the
U.S. Holder is an exempt recipient or establishes an exemption.  Compliance with
the identification procedures described in the

                                       29

<PAGE>

preceding section would establish an exemption from backup withholding for those
non-U.S. Holders who are not exempt recipients.

         In addition, upon the sale of a Note by or through a broker, the broker
must  withhold 31% of the entire  purchase  price,  unless either (i) the broker
determines  that the seller is a corporation  or other exempt  recipient or (ii)
the seller provides,  in the required manner,  certain  identifying  information
and, in the case of a non-U.S.  Holder, certifies that such seller is a non-U.S.
Holder (and certain other conditions are met). Such a sale must also be reported
by the  broker to the IRS,  unless  either (i) the  broker  determines  that the
seller is an exempt recipient or (ii) the seller  certifies its non-U.S.  status
(and certain other conditions are met).  Certification of the registered owner's
non-U.S.  status  would be made  normally on an IRS Form W-8 under  penalties of
perjury,  although  in  certain  cases  it  may  be  possible  to  submit  other
documentary evidence.

         Any amounts withheld under the backup  withholding rules from a payment
to a  beneficial  owner  would be allowed as a refund or a credit  against  such
beneficial  owner's  United  States  Federal  income tax  provided  the required
information is furnished to the IRS.


                              PLAN OF DISTRIBUTION

         Each broker-dealer that receives New Notes for its own account pursuant
to the Exchange  Offer must  acknowledge  that it will  deliver a prospectus  in
connection  with any resale of such New  Notes.  This  Prospectus,  as it may be
amended or  supplemented  from time to time, may be used by a  broker-dealer  in
connection  with  resales of New Notes  received in exchange for Old Notes where
such Old Notes were  acquired as a result of  market-making  activities or other
trading  activities.  The  Company  has agreed for a period of at least 120 days
after the consummation of the Exchange Offer to make this Prospectus, as amended
or supplemented,  available to any  broker-dealer for use in connection with any
such  resale.  In  addition,  until  __________,  1998,  all  dealers  effecting
transactions in the New Notes may be required to deliver a prospectus.

         The Company will not receive any proceeds from any sale of New Notes by
broker-dealers.  New Notes  received by  broker-dealers  for their own  accounts
pursuant  to the  Exchange  Offer  may be sold  from time to time in one or more
transactions in the over-the-counter  market, in negotiated transactions through
the  writing  of options on the New Notes or a  combination  of such  methods of
resale,  at market prices prevailing at the time of resale, at prices related to
such prevailing  market prices or at negotiated  prices.  Any such resale may be
made directly to purchasers or to or through  brokers or dealers who may receive
compensation   in  the  form  of  commissions  or  concessions   from  any  such
broker-dealer  and/or the  purchasers of any such New Notes.  Any  broker-dealer
that resells New Notes that were received by it for its own account  pursuant to
the Exchange Offer and any broker or dealer that  participates in a distribution
of such New Notes may be deemed to be an "underwriter" within the meaning of the
Securities  Act  and  any  profit  on any  such  resale  of New  Notes  and  any
commissions  or  concessions  received  by any such  persons may be deemed to be
underwriting  compensation  under the Securities  Act. The Letter of Transmittal
states  that  by  acknowledging  that  it  will  deliver  and  by  delivering  a
prospectus,  a  broker-dealer  will  not  be  deemed  to  admit  that  it  is an
"underwriter" within the meaning of the Securities Act.

         For a  period  of at least  120  days  after  the  consummation  of the
Exchange  Offer,  the  Company  will  promptly  send  additional  copies of this
Prospectus   and  any  amendment  or  supplement  to  this   Prospectus  to  any
broker-dealer  that requests such  documents in the Letter to  Transmittal.  The
Company has agreed to pay all expenses incident to the Exchange Offer (including
the expenses of any special counsel for the holders of the Old Notes) other than
commissions  or  concessions  of any brokers or dealers and will  indemnify  the
holders of the Old Notes  participating  in the Exchange  Offer  (including  any
broker-dealers)  against certain  liabilities,  including  liabilities under the
Securities Act.


                              TRANSFER RESTRICTIONS

         Unless and until an Old Note is  exchanged  for a New Note  pursuant to
the Exchange Offer, its will bear the following legend on the face thereof:

              Unaudited Pro Forma Consolidated Financial Statements

         The  following  unaudited  pro forma  consolidated  balance sheet as of
December  31, 1997 and the  consolidated  statement of income for the year ended
December 31, 1997,  present the consolidated  financial position and the results
of  operations  of Health  and  Retirement  Properties  Trust  and  consolidated
subsidiaries  (the "Company") as if the  transactions  described in the notes to
unaudited financial  statements were consummated on January 1, 1997.  Additional
information  with  respect to such  transactions  is provided  in the  Company's
Annual  Report on Form 10-K for its fiscal year ended  December 31, 1997 (and in
materials incorporated by reference therein), which is incorporated by reference
into  this  Prospectus.   These  unaudited  pro  forma  consolidated   financial
statements  should  be read in  connection  with,  and are  qualified  in  their
entirety by reference to, the separate consolidated  financial statements of the
Company for the year ended December 31, 1997,  included in the Company's Current
Report on Form 8-K dated February 27, 1998,  which is  incorporated by reference
into  this  Prospectus.   These  unaudited  pro  forma  consolidated   financial
statements  are not  necessarily  indicative of the  financial  position and the
expected results of operations of the Company for any future period. Differences
could result from, among other  considerations,  future changes in the Company's
portfolio  of  investments,  changes in interest  rates,  changes in the capital
structure of the Company,  delays in the  acquisition of certain  properties and
changes in property level operating expenses.

     acquisitions.

     and amortization and general and  administrative  expenses arising from the
     Company's  acquisition of West 34th Street in New York City, as well as the

Item 22. 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, as amended (the "Securities Act");

         (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


                                      II-1
<PAGE>
         (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.

         (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.

         (4) 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.

         (5) That prior to any public  reoffering of the  securities  registered
         hereunder  through  the  use of a  prospectus  which  is  part  of this
         Registration  Statement,  by any person or party who is deemed to be an
         underwriter   within  the  meaning  of  Rule  145(c),   the  Registrant
         undertakes that such reoffering prospectus will contain the information
         called  for  by  the  applicable  registration  form  with  respect  to
         reofferings by persons who may be deemed  underwriters,  in addition to
         the information called for by the other items of the applicable form;

         (6) That every prospectus:  (i) that is filed pursuant to paragraph (4)
         immediately  preceding,  or (ii) that purports to meet the requirements
         of Section  10(a)(3) of the  Securities  Act and is used in  connection
         with an offering of securities  subject to Rule 145, will be filed as a
         part of an amendment to the Registration Statement and will not be used
         until  such   amendment  is  effective,   and  that,  for  purposes  of
         determining   any  liability   under  the  Securities  Act,  each  such
         post-effective  amendment  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;

         (7) To respond to requests  for  information  that is  incorporated  by
         reference  into the prospectus  pursuant to Item 4, 10(b),  11 or 13 of
         this form,  within one business day of receipt of such request,  and to
         send the  incorporated  documents by first class mail or other  equally
         prompt means.  This includes  information  contained in documents filed
         subsequent to the effective date of this Registration Statement through
         the date of responding to the request.

         (8) To supply by means of a post-effective  amendment,  all information
         concerning  a  transaction,  and the company  being  acquired  involved
         therein,  that was not the subject of and included in the  Registration
         Statement when it became effective.

         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

                                      II-2

<PAGE>



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.

                  (1) a statement that each individual  signing such certificate
         or opinion  has read such  condition  or covenant  and the  definitions
         herein relating thereto;

several  matters are required to be certified by or covered by an opinion of any
specified  Person, it is not necessary that all such matters be certified by, or
covered by the opinion of, only one such Person, or that they be so certified or
covered by only one document, but one such Person may certify or give an opinion
as to some matters and one or more other such Persons as to other  matters,  and
any such  Person may  certify  or give an  opinion as to such  matters in one or
several documents.

         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
the exercise of reasonable  care should know,  that the opinion,  certificate or
representations  with  respect  to the  matters  upon which his  certificate  or
opinion is based are  erroneous.  Any such  Opinion of Counsel,  certificate  or
representations may be based,  insofar as it relates to factual matters,  upon a
certificate or opinion of, or representations  by, an officer or officers of the
Company  or any  Subsidiary  stating  that the  information  as to such  factual
matters is in the  possession  of the  Company or such  Subsidiary,  unless such
counsel  knows that the  certificate  or opinion or  representations  as to such
matters are erroneous.

         Where any  Person is  required  to make,  give or  execute  two or more
applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
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

                                        7
<PAGE>

any  meeting of Holders of  Securities  of such  series  duly called and held in
accordance  with  the  provisions  of  Article  15,  or a  combination  of  such
instruments and any such record.  Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company.  Such  instrument  or  instruments  and any such record (and the
action embodied therein and evidenced  thereby) are herein sometimes referred to
as the "Act" of the Holders  signing such instrument or instruments or so voting
at any such meeting.  Proof of execution of any such  instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security,  shall
be sufficient  for any purpose of this  Indenture and conclusive in favor of the
Trustee and the Company and any agent of the Trustee or the Company,  if made in
the manner  provided  in this  Section.  The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1506.

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

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

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

<PAGE>


                  (1) the  Trustee  by any  Holder  or by the  Company  shall be
         sufficient  for every purpose  hereunder if made,  given,  furnished or
         filed in writing to or with the Trustee at its Corporate  Trust Office,
         Attention:   Corporate  Trust  Department  Re:  Health  and  Retirement
         Properties Trust Notes due 2002; 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.

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

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

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

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

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

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

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

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

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

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

         Section 112.  Legal  Holidays.  In any case where any Interest  Payment
Date,  Redemption  Date,  Repayment  Date,  sinking  fund payment  date,  Stated
Maturity or Maturity of any Security shall not be a Business Day at any Place of
Payment,  then  (notwithstanding  any other  provision of this  Indenture or any
Security or coupon other than a provision in the  Securities of any series which
specifically states that such provision shall apply in lieu hereof),  payment of
interest or any Additional Amounts or principal (and premium, if any) or sinking
fund payment need not be made at such Place of Payment on such date,  but may be
made on the next succeeding  Business Day at such Place of Payment with the same
force and  effect as if made on the  Interest  Payment  Date,  Redemption  Date,
Repayment  Date or sinking  fund  payment  date,  or at the Stated  Maturity  or
Maturity;  provided  that no interest  shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date, Repayment
Date,  sinking fund payment date,  Stated Maturity or Maturity,  as the case may
be.

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

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

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.

         The  Securities  may be issued in one or more  series.  There  shall be
established in one or more Board Resolutions or pursuant to authority granted by
one or more  Board  Resolutions  and,  subject  to  Section  303 set  forth,  or
determined in the manner provided, in an Officers'  Certificate,  or established

         premium,  if any) or interest,  if any, on the Securities of the series
         may be determined  with reference to an index,  formula or other method

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

                  (15)  whether  Securities  of the series are to be issuable as
         Registered  Securities,  Bearer Securities (with or without coupons) or
         both,  any  restrictions  applicable to the offer,  sale or delivery of
         Bearer  Securities  and the terms upon which Bearer  Securities  of the
         series may be exchanged  for  Registered  Securities  of the series and
         vice versa (if permitted by applicable laws and  regulations),  whether
         any Securities of the series are to be issuable  initially in temporary
         global form and whether any Securities of the series are to be issuable
         in permanent  global form with or without  coupons and, if so,  whether
         beneficial  owners of interests in any such permanent  global  Security
         may exchange such  interests for  Securities of such series and of like
         tenor of any authorized  form and  denomination  and the  circumstances
         under which any such  exchanges may occur,  if other than in the manner
         provided in Section 305,  and, if  Registered  Securities of the series

         any  interest  payable on a  temporary  global  Security on an Interest

         in addition to or in lieu of any of the provisions of Article 14;

                  (19) if the  Securities  of such  series are to be issuable in
         definitive  form  (whether  upon  original  issue or upon exchange of a
         temporary  Security  of such  series)  only  upon  receipt  of  certain
         certificates or other  documents or  satisfaction of other  conditions,
         then  the  form  and/or  terms  of  such  certificates,   documents  or
         conditions;

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

                                       13
<PAGE>

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

                  (22) the  obligation,  if any,  of the  Company  to permit the
         conversion  of the  Securities  of such series  into  Common  Shares or
         Preferred  Shares of the Company or other  securities,  as the case may
         be, and the terms and conditions  upon which such  conversion  shall be
         effected (including,  without limitation,  the initial conversion price
         or rate,  the  conversion  period,  any  adjustment  of the  applicable
         conversion  price and any  requirements  relative to the reservation of
         such shares for purposes of conversion);

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

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

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

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

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

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

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

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

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

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

                                       15
<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.  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

                                       16

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  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.

                                       17

         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 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

                                       18
<PAGE>

Trustee shall  authenticate and deliver,  definitive  Securities of like series,
rank, tenor and terms in definitive form in an aggregate  principal amount equal
to the principal amount of such global Security or Securities. If any beneficial
owner of an interest in a permanent  global  Security is  otherwise  entitled to
exchange  such  interest  for  Securities  of such  series and of like tenor and
principal amount of another  authorized form and  denomination,  as specified as
contemplated by Section 301 and provided that any applicable  notice provided in
the permanent  global Security shall have been given,  then without  unnecessary
delay but in any event no later than the  earliest  date on which such  interest
may  be  so  exchanged,  the  Company  shall  execute,  and  the  Trustee  shall
authenticate and deliver,  definitive  Securities in aggregate  principal amount
equal to the  principal  amount  of such  beneficial  owner's  interest  in such
permanent global Security. On or after the earliest date on which such interests
may be so exchanged,  such permanent  global  Security shall be surrendered  for
exchange by DTC or such other  depositary  as shall be  specified in the Company
Order with  respect  thereto to the  Trustee,  as the  Company's  agent for such
purpose;  provided,  however,  that no such  exchanges may occur during a period
beginning at the opening of business 15 days before any  selection of Securities
to be redeemed  and ending on the relevant  Redemption  Date if the Security for
which  exchange is requested  may be among those  selected for  redemption;  and
provided further that no Bearer Security  delivered in exchange for a portion of
a  permanent  global  Security  shall be mailed or  otherwise  delivered  to any
location in the United  States.  If a Registered  Security is issued in exchange
for any portion of a permanent  global  Security  after the close of business at
the office or agency where such exchange  occurs on (i) any Regular  Record Date
and before the  opening of  business  at such  office or agency on the  relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the  related  proposed  date for payment of
Defaulted Interest, interest or Defaulted Interest, as the case may be, will not
be payable on such Interest  Payment Date or proposed  date for payment,  as the
case may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment,  as the case may be, only to
the Person to whom interest in respect of such portion or such permanent  global
Security is payable in accordance with the provisions of this Indenture.

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

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

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

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

                                       19
<PAGE>

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 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.

                                       20
<PAGE>

         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 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  canceled 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  canceled by the Trustee.  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  canceled as provided in this  Section,  except as
expressly  permitted by this Indenture.  Canceled 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.

         thereto  (other  than (i)  coupons  appertaining  to Bearer  Securities
         surrendered  for exchange for Registered  Securities and maturing after

         the Trustee for cancellation; or

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

                                    year under arrangements  satisfactory to the
                                    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
         and  discharge  the entire  indebtedness  on such  Securities  and such
         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
         payable hereunder by the Company; and

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

The obligations of the Company to the Trustee and any predecessor  Trustee under
Section 606, the  obligations of the Company to any  Authenticating  Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section,  the obligations of the
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
pursuant to Section 401 shall be held in trust and applied by it, in  accordance
with the provisions of the Securities,  the coupons 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 Persons
entitled thereto,  of the principal (and premium,  if any), and any interest and
Additional  Amounts  for whose  payment  such money has been  deposited  with or
received by the Trustee,  but such money need not be segregated from other funds
except to the extent required by law.

                                    REMEDIES

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

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

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

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

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

                  (5) a  default  under  any  bond,  debenture,  note  or  other
         evidence  of  indebtedness  of the  Company,  or  under  any  mortgage,
         indenture or other instrument of the Company  (including a default with
         respect to Securities of any series other than that series) under which
         there may be issued or by which there may be secured  any  indebtedness
         of the  Company  (or by any  Subsidiary,  the  repayment  of which  the
         Company has guaranteed or for which the Company is directly responsible
         or liable as obligor  or  guarantor),  whether  such  indebtedness  now
         exists or shall hereafter be created,  which default shall constitute a
         failure to pay an aggregate  principal amount exceeding  $20,000,000 of
         such  indebtedness  when due and payable  after the  expiration  of any
         applicable grace period with respect thereto and shall have resulted in
         such   indebtedness  in  an  aggregate   principal   amount   exceeding
         $20,000,000  becoming or being  declared  due and payable  prior to the
         date on which it would  otherwise have become due and payable,  without
         such indebtedness  having been discharged,  or such acceleration having
         been  rescinded  or  annulled,  within a period of 10 days after  there
         shall have been given,  by registered or certified mail, to the Company
         by the  Trustee or to the  Company and the Trustee by the Holders of at
         least a majority in principal  amount of the Outstanding  Securities of
         that series a written notice  specifying such default and requiring the
         Company  to cause  such  indebtedness  to be  discharged  or cause such
         acceleration  to be  rescinded or annulled and stating that such notice
         is a "Notice of Default" hereunder; or

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

                           (A) commences a voluntary case,

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

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

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

                                       24
<PAGE>

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

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

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

                           (C)  orders  the  liquidation  of the  Company or any
                  Significant Subsidiary,

         and the order or decree remains unstayed and in effect for 90 days; or

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

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

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

                                       25
<PAGE>

                  (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
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;


                                       26
<PAGE>

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

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

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

                  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;

                                       27
<PAGE>


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.

         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

                                       28
<PAGE>

                  (2) in respect of a covenant or  provision  hereof which under
         Article 9 cannot be  modified  or amended  without  the  consent of the
         Holder of each Outstanding Security of such series affected.

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

         Section  514.  Waiver of Usury,  Stay or  Extension  Laws.  The Company
covenants  (to the extent  that it may  lawfully  do so) that it will not at any
time  insist  upon,  or plead,  or in any  manner  whatsoever  claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted,  now
or at any time  hereafter  in  force,  which may  affect  the  covenants  or the
performance  of this  Indenture;  and the  Company  (to the  extent  that it may
lawfully 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 6

                                   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;

                                       29
<PAGE>

                  (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;

                  (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:


                                       30
<PAGE>

                  (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);

                  (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

                                       31
<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 9 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  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

                                       32
<PAGE>

retiring  Trustee,  and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the  administration
of the trusts  hereunder  by more than one  Trustee,  it being  understood  that
nothing herein or in such supplemental  indenture shall constitute such Trustees
co-trustees  of the same trust and that each such Trustee  shall be trustee of a
trust or trusts hereunder  separate and apart from any trust or trusts hereunder
administered  by any other such Trustee;  and upon the execution and delivery of
such  supplemental  indenture the resignation or removal of the retiring Trustee
shall become  effective to the extent  provided  therein and each such successor
Trustee,  without any further act, deed or conveyance,  shall become vested with
all the rights,  powers,  trusts and duties of the retiring Trustee with respect
to the  Securities  of that or those  series  to which the  appointment  of such
successor  Trustee  relates;  but,  on request of the  Company or any  successor
Trustee,  such retiring Trustee shall duly assign,  transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the  appointment
of such successor Trustee relates.

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

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

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

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

                                       33
<PAGE>

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.

         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

                  (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

                                       36

         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:

                  (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

                                       37

         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
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 10

                                    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

                                       38
<PAGE>

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

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

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

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

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

         Section 1004.  Existence.  Subject to Article 8, the Company will do or
cause to be done all things  necessary  to  preserve  and keep in full force and
effect  its  existence,  rights  (declaration  and  statutory)  and  franchises;
provided,  however, that the Company shall not be required to preserve any right
or franchise if the Board shall  determine that the  preservation  thereof is no
longer desirable in the conduct of the business of the Company.

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

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

         Section 1006.  Statement as to Compliance.  The Company will deliver to
the  Trustee,  within  120  days  after  the end of each  fiscal  year,  a brief
certificate from the principal executive officer, principal financial officer or
principal  accounting  officer  as to  his  or her  knowledge  of the  Company's
compliance  with all conditions  and covenants  under this Indenture and, in the
event of any  noncompliance,  specifying such  noncompliance  and the nature and
status  thereof.  For purposes of this Section 1006,  such  compliance  shall be
determined  without regard to any period of grace or requirement of notice under
this Indenture.

         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

                                       41
<PAGE>

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 11

                            REDEMPTION OF SECURITIES

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

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

                                       42
<PAGE>

         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,

                  (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,

         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  12,
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.

                                       43

         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.

         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 12) 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 12

                                  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

                                       44
<PAGE>

to reduction  as provided in Section  1202.  Each sinking fund payment  shall be
applied to the  redemption  of  Securities  of any series as provided for by the
terms of Securities of such series.

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

         Section 1203.  Redemption of Securities for Sinking Fund. Not less than
60 days prior to each sinking fund  payment date for  Securities  of any series,
the Company will deliver to the Trustee an Officers' Certificate  specifying the
amount of the next  ensuing  mandatory  sinking  fund  payment  for that  series
pursuant to the terms of that 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 13

                       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

                                       45
<PAGE>

Holder or by the Holder's attorney duly authorized in writing or (2) a telegram,
telex, facsimile transmission or a letter from a member of a national securities
exchange, or the National Association of Securities Dealers, Inc. ("NASD"), or a
commercial  bank or trust company in the United States setting forth the name of
the Holder of the Security,  the principal amount of the Security, the principal
amount of the Security to be repaid,  the CUSIP number, if any, or a description
of the tenor and terms of the  Security,  a  statement  that the option to elect
repayment  is being  exercised  thereby and a guarantee  that the Security to be
repaid,  together  with  the  duly  completed  form  entitled  "Option  to Elect
Repayment" on the reverse of the  Security,  will be received by the Trustee not
later  than the  fifth  Business  Day after  the date of such  telegram,  telex,
facsimile transmission or letter; provided,  however, that such telegram, telex,
facsimile  transmission  or letter shall only be effective if such  Security and
form duly  completed are received by the Trustee by such fifth  Business Day. If
less  than the  entire  principal  amount  of such  Security  is to be repaid in
accordance  with the  terms  of such  Security,  the  principal  amount  of such
Security to be repaid, in increments of the minimum  denomination for Securities
of such  series,  and the  denomination  or  denominations  of the  Security  or
Securities to be issued to the Holder for the portion of the principal amount of
such  Security  surrendered  that is not to be repaid,  must be  specified.  The
principal  amount of any security  providing  for repayment at the option of the
Holder  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,

                                       46
<PAGE>

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 14

                       DEFEASANCE AND COVENANT DEFEASANCE

         Section  1401.  Applicability  of Article;  Company's  Option to Effect
Defeasance or Covenant  Defeasance.  If,  pursuant to Section 301,  provision is
made for  either  or both of (a)  defeasance  of the  Securities  of or within a
series under  Section 1402 or (b) covenant  defeasance  of the  Securities of or
within a series  under  Section  1403,  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 14.  Subject to  compliance  with this
Article  14,  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 14  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

                  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

                  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.

                  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.

this  Indenture  to be made,  given or taken by  Holders of  Securities  of such
series.

         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 than 21 nor more than 180 days prior to the

Securities of such series for any purpose  specified in Section 1501, by written

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
(1) a Holder of one or more  Outstanding  Securities  of such  series,  or (2) a

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

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

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

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,
whether or not present or represented at the meeting.

         Notwithstanding  the foregoing  provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of  Securities  of any series with
respect to any  request,  demand,  authorization,  direction,  notice,  consent,
waiver or other action that this Indenture expressly provides may be made, given

         meeting; and

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

         Section 1505.  Determination of Voting Rights;  Conduct and Adjournment
of Meetings.

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

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

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

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

         Section 1506. Counting Votes and Recording Action of Meetings. The vote
upon any  resolution  submitted to any meeting of Holders of  Securities  of any
series shall be by written  ballots on which shall be subscribed  the signatures
of the Holders of Securities of such series or of their representatives by proxy
and the principal  amounts and serial numbers of the  Outstanding  Securities of
such series held or represented  by them. The permanent  chairman of the meeting
shall  appoint  two  inspectors  of votes who shall  count all votes cast at the
meeting  for or  against  any  resolution  and who shall  make and file with the
secretary  of the meeting  their  verified  written  reports in duplicate of all
votes cast at the meeting.  A record, at least in duplicate,  of the proceedings
of each meeting of Holders of  Securities of any Series shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the

                                       51
<PAGE>

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 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.

Trustee of a written  certification  from the transferor to the effect that such
transfer is

                                       -5-
<PAGE>

being made in accordance  with Rule 903 or 904 of Regulation S or Rule 144 under
the Securities Act (an "Unrestricted Global Note Certification"). Any beneficial
interest in one of the Global  Notes that is  transferred  to a Person who takes
delivery  in the  form of an  interest  in the  other  Global  Note  will,  upon
transfer,  cease to be an  interest  in such  Global  Note and  will  become  an
interest in the other Global Note and,  accordingly,  will thereafter be subject
to all transfer restrictions and other procedures and restrictions applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.

         Ownership of  beneficial  interests in a Global Note will be limited to
Persons  who have  accounts  with DTC ("DTC  Participants")  or Persons who hold
interests  through DTC  Participants.  Ownership of beneficial  interests in the
Global  Notes  will be shown on,  and the  transfer  of that  ownership  will be
effected only through, records maintained by DTC or its nominee (with respect to
interests of DTC Participants) and the records of DTC Participants (with respect
to interests of Persons other than DTC Participants).

         Individual  definitive  Notes  issued in  exchange  for the  Restricted
Global Note will bear, and be subject to, such legend as the Company requires in
order to assure  compliance with any applicable law (which  requirement shall be
evidenced  by  delivery  to the Trustee of a Company  Order  setting  forth such
legend). The holder of a restricted individual definitive Note may transfer such
Note,  subject to  compliance  with the  provisions of the legend as provided in
paragraph (d) below. Upon the transfer, exchange or replacement of Notes bearing
the legend,  or upon specific  request for removal of the legend on a Note,  the
Company will deliver and the Trustee will authenticate only Notes that bear such
legend,  or will refuse to remove such legend,  as the case may be, unless there
is  delivered to the Company such  satisfactory  evidence,  which may include an
opinion of counsel,  as may reasonably be required by the Company,  that neither
the legend nor the  restrictions  on transfer set forth  therein are required to
ensure  compliance  with  the  provisions  of the  Securities  Act.  Before  any
individual  definitive Note may be transferred to a Person who takes delivery in
the form of an interest in any Global Note, the  transferor  will be required to
provide the Trustee with a Restricted Global Note  Certification or Unrestricted
Global Note Certification, as the case may be.

         (b) Principal Repayment;  Currency. The Stated Maturity of the Notes is
December 18, 2002,  provided,  however, the Notes may be earlier redeemed at the
option of the Company as provided in paragraph (c) below.  The principal of each
Note  payable  on its  maturity  date  shall be paid  against  presentation  and
surrender  thereof  at  the  Corporate  Trust  Office  of the  Trustee,  located
initially at Two International Place, Boston,  Massachusetts 02110, in such coin
or currency  of the United  States of America as at the time of payment is legal
tender for the  payment of public or private  debts.  The  Company  will not pay
Additional Amounts (as defined in the Indenture) on the Notes.

         (c)  Redemption  at the Option of the Company.  Prior to September  18,
2002,  the Notes will be subject to  redemption at any time at the option of the
Company,  in  whole or in part,  upon  not less  than 30 nor more  than 60 day's
notice to each Holder of Notes to be redeemed  at its address  appearing  in the
Security  Register,  at a price equal to the sum of (i) the principal  amount of
the Notes being  redeemed,  plus  accrued  and unpaid  interest  and  Liquidated
Damages,  if any, to but excluding the applicable  redemption  date and (ii) the
Make-Whole Amount. On and after September 18, 2002, the Notes will be subject to
redemption at any time at the option of the Company, in whole

                                       -6-
<PAGE>

or in part, upon not less than 30 nor more than 60 days' notice, at a redemption
price equal to the sum of the principal  amount of the Notes being redeemed plus
accrued and unpaid interest and Liquidated Damages, if any, to but excluding the
applicable redemption date.

         (d)  Restrictive  Legends.  Unless and until a Note is exchanged for an
Exchange  Note in  connection  with an  effective  registration  pursuant to the
Registration Rights Agreement,  each Note shall bear the following legend on the
face thereof:

         THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
         AS  AMENDED  (THE  "SECURITIES  ACT"),  AND  SUCH  SECURITY  MAY NOT BE

         FROM  REGISTRATION  PROVIDED BY RULE 144 UNDER THE  SECURITIES  ACT (IF
         AVAILABLE),   OR  (5)  IN  A  TRANSACTION  OTHERWISE  EXEMPT  FROM  THE

                              ADDITIONAL COVENANTS

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

         (a)      Limitations on Incurrence of Debt.

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

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

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

                                       -8-
<PAGE>

         of such four-quarter period, the related acquisition had occurred as of
         the first day of such period with appropriate  adjustments with respect
         to such acquisition being included in such pro forma  calculation;  and
         (iv) in the case of any  acquisition  or  disposition by the Company or
         its Subsidiaries of any asset or group of assets since the first day of
         such four-quarter period, whether by merger, stock purchase or sale, or
         asset purchase or sale, such  acquisition or disposition or any related
         repayment  of Debt had occurred as of the first day of such period with
         the  appropriate  adjustments  with  respect  to  such  acquisition  or
         disposition being included in such pro forma calculation.

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

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

                                    ARTICLE 4

                          ADDITIONAL EVENTS OF DEFAULT

         For purposes of this Supplemental  Indenture and the Notes, in addition
to the Events of Default  set forth in Section  5.1 of the  Indenture,  it shall
also  constitute  an "Event of Default"  if an event of default  under any bond,
debenture,  note or other evidence of indebtedness of the Company  (including an
event of default with respect to any other series of  securities),  or under any
mortgage,  indenture or other instrument of the Company under which there may be
issued or by which there may be secured or  evidenced  any  indebtedness  of the
Company (or by any Subsidiary, the repayment of which the Company has guaranteed
or for which the  Company  is  directly  responsible  or  liable as  obligor  or
guarantor),  whether such indebtedness now exists or shall hereafter be created,
shall  happen  and  shall  result in an  aggregate  principal  amount  exceeding
$20,000,000  becoming or being  declared  due and  payable  prior to the date on
which it would otherwise have become due and payable,  without such indebtedness
having been discharged,  or such acceleration having been rescinded or annulled,
within a period of ten days after there shall have been given,  by registered or
certified  mail, to the Company by the Trustee or to the Company and the Trustee
by the holders of at least 25% in principal  amount of the outstanding  Notes, a
written notice  specifying  such default and requiring the Company to cause such
indebtedness  to be  discharged  or cause such  acceleration  to be rescinded or
annulled and stating that such notice is a "Notice of Default" hereunder.

                                    ARTICLE 5

                                  EFFECTIVENESS

the Company and the Trustee in accordance with Article Nine of the Indenture. As
supplemented  hereby,  the Indenture is hereby  confirmed as being in full force

         Section 6.1 In the event any provision of this  Supplemental  Indenture

hereof or any provision of the Indenture.

construed in accordance with the laws of The Commonwealth of Massachusetts.

                     HEALTH AND RETIREMENT PROPERTIES TRUST

                    6 3/4% Senior Notes due December 18, 2002

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

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

         The Company shall pay in cash interest on the principal  amount of this
Note  at  the  rate  per  annum  of  6  3/4%.  The  Company  will  pay  interest
semi-annually in arrears on June 18 and December 18 of each year,  commencing on
June 18,  1998 or if any  such  day is not a  Business  Day (as  defined  in the
Indenture),  on the next  succeeding  Business  Day (each an  "Interest  Payment
Date"), to Holders of record on the immediately preceding June 3 and December 3.

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

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

         3.  Indenture.  The Company  issued the Notes under an Indenture  and a
Supplemental  Indenture,  each dated as of December  18, 1997 (the  "Indenture")
between the Company and the Trustee. The terms of the Notes include those stated
in the  Indenture and those made part of the Indenture by reference to the Trust
Indenture  Act of 1939 (15 U.S.  Code ss.ss.  77aaa-77bbbb)  as in effect on the
date of the Indenture.  The Notes are subject to all such terms,  and Holders of
the Notes are  referred to the  Indenture  and such act for a statement  of such
terms. The terms of the Indenture shall govern any  inconsistencies  between the
Indenture and the Notes.  The Notes are  unsecured  general  obligations  of the
Company limited to $150,000,000 in aggregate principal amount.

         4. Optional Redemption.  Prior to September 18, 2002, the Notes will be
subject to redemption  at any time at the option of the Company,  in whole or in
part, upon not less than 30 nor more than 60 days' notice, at a redemption price
equal to the sum of (i) the principal  amount of the Notes being redeemed,  plus
accrued  and  unpaid  interest  and  Liquidated   Damages  (as  defined  in  the
Supplemental Indenture), if any, to but excluding the applicable redemption date
and (ii) the Make- Whole Amount. On and after September 18, 2002, the Notes will
be subject to redemption  at any time at the option of the Company,  in whole or
in part, upon not less than 30 nor more than 60 days'

                                      A - 2
<PAGE>

notice,  at a redemption  price equal to the sum of (i) the principal  amount of
the Notes being  redeemed,  plus  accrued  and unpaid  interest  and  Liquidated
Damages, if any, to but excluding the applicable redemption date.

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

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

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

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

         6. Notice of Redemption.  Notice of redemption shall be mailed at least
30 days but not more than 60 days before the  redemption  date to each Holder of

but only in whole multiples of $1,000,  unless all of the Notes held by a Holder
are to be redeemed.  On and after the redemption date, interest ceases to accrue
on Notes or portions of them called for redemption.

         7. Denominations,  Transfer, Exchange. The Notes are in registered form
without coupons in denominations of $100,000 and integral multiples of $1,000 in

Registrar and the Trustee may require a Holder,  among other things,  to furnish
appropriate  endorsements  and transfer  documents and to pay any taxes and fees
required by law or permitted by the  Indenture.  The Registrar need not exchange
or  register  the  transfer  of any  Note  or  portion  of a Note  selected  for
redemption. Also, it need not exchange or register the transfer of any Notes for
a period of 15 days before the mailing of a notice of  redemption  of Notes,  or
during the period between a record date and the  corresponding  Interest Payment
Date.

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

         9. Actions of Holders. The Indenture contains provisions permitting the
holders of not less than a majority  of the  aggregate  principal  amount of the

demand,  authorization,  direction,  notice,  consent,  waiver  or other  action
provided  in the  Indenture  to be made,  given or taken by the  holders  of the
Notes, including without limitation,  waiving (a) compliance by the Company with
certain  provisions of the  Indenture,  and (b) certain past defaults  under the
Indenture and their consequences. Any resolution passed or decision taken at any
meeting of the holders of the Notes in  accordance  with the  provisions  of the
Indenture  shall be conclusive and binding upon such holders and upon all future
holders of this Note and other Notes  issued upon the  registration  of transfer
hereof or in exchange heretofore or in lieu hereof

         10. Persons Deemed Owners. The Company,  the Trustee,  and any agent of
the Company or the Trustee may deem and treat the Person in whose name this Note

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

Ladies and Gentlemen:

         In connection with the registration by Health and Retirement Properties
Trust, a Maryland real estate investment trust (the "Company"),  of $150,000,000
of Senior  Notes due 2002 (the  "Notes"),  which  Notes will be issued  under an
indenture and a supplement thereto  (collectively,  the "Indenture") relating to
the Notes by and between the Company and State Street Bank and Trust Company, as
Trustee (the "Trustee"), 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-4,  under the Securities
Act of 1933, as amended (the "Securities Act"), to be filed on or about the date
hereof. 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 post-effective amendments thereto).

         In  connection  with this  opinion,  we have examined and relied upon a
copy of the  Registration  Statement 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  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.

         To the extent that the  obligations  of the Company under the Indenture
may be dependent upon such matters, we have assumed for purposes of this opinion
that the Trustee is duly organized,  validly existing and in good standing under
the laws of its jurisdiction of organization, and is duly qualified to engage in
the activities  contemplated by, and has the requisite  organizational and legal
authority to perform its obligations under, the Indenture, that the Trustee will
be in compliance, generally with respect to acting as trustee or agent under the
Indenture, with all applicable laws and regulations, and that the Indenture will
be the valid and  binding  agreement  of the  Trustee,  enforceable  against the
Trustee in accordance with its 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 being
filed herewith as Exhibit 5.2 to the Registration Statement,  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, the Notes 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  shall have been qualified  under the
Trust Indenture Act of 1939, as amended,  and (ii) the Notes shall have been (A)
duly executed by the Company and authenticated by the Trustee as provided in the
Indenture and (B) shall have been duly delivered to the purchasers  thereof,  as
described in the Registration  Statement and the prospectus included therein and
as provided in the Indenture.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration  Statement  and to the  reference  to our  firm  in the  Prospectus
forming a part of the Registration  Statement. In giving such consent, we do not
thereby  admit that we come  within the  category  of persons  whose  consent is
required  under Section 7 of the Act or under the rules and  regulations  of the
Commission promulgated thereunder.

                                                    Very truly yours,

Re:  Health and Retirement Properties Trust

Ladies and Gentlemen:

         We have acted as special  Maryland  counsel  for Health and  Retirement
Properties Trust, a real estate investment trust organized under the laws of the
State of Maryland (the "Trust"),  in connection with the registration  statement
on form S-4 (the  "Registration  Statement")  of the Trust  with  respect to the
registration of $150,000,000  aggregate  principal amount of 6 3/4% Senior Notes
due 2002 (the "Exchange Notes").

         In such  capacity,  we have reviewed the  Registration  Statement,  the
Indenture  dated as of December 18, 1997 between the Trust and State Street Bank
and Trust Company (the "Indenture"),  the Supplemental  Indenture dated December
18,  1997  between  the Trust  and State  Street  Bank and  Trust  Company  (the
"Supplemental  Indenture"),  the Amended and Restated  Declaration of Trust (the
"Declaration of Trust"),  the Bylaws of the Trust (the  "Bylaws"),  the Offering
Memorandum  dated  December 15, 1997  relating to the  offering of  $150,000,000
aggregate  principal  amount of 6 3/4% Senior Notes due 2002,  of the Trust (the
"Initial Notes"), certain minutes of proceedings of the Board of Trustees of the
Trust,  a good  standing  certificate  dated as of a recent  date from the State
Department of Assessments  and Taxation of Maryland,  and such other  documents,
trust records and certificates of public officials and officers of the Trust and
other instruments, and have conducted such other investigations of fact and law,
as we have deemed  necessary  or advisable  for the  purposes of rendering  this
opinion.

         In  rendering  this  opinion  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,  the  conformity  to original
documents of all documents  submitted to us as certified or  photostatic  copies
(and the  authenticity  of the  originals of such  copies),  and that all public
records






<PAGE>




reviewed are accurate and  complete.  We have further  assumed that the Purchase
Agreement  and the  Indenture  have been duly  executed and delivered by all the
parties  thereto  other than the  Trust.  As to various  facts  material  to the
opinions set forth herein (including,  without limitation,  the number of shares
of capital  stock  outstanding,  the  receipt  of  consideration  therefor,  the
execution of  documents on behalf of the Trust and the absence of any  violation
by the Trust of any applicable Maryland law), we have relied without independent
verification  upon  certificates of public officials and upon facts certified to
us by officers of the Trust as contained in a certificate  of such officers (the
"Officers'  Certificate").  Capitalized  terms used but not defined herein shall
have the meanings specified in the Purchase Agreement.

              Based   upon  the   foregoing,   having   regard  for  such  legal
considerations  as we deem  relevant,  we are of the  opinion  and advise you as
follows:

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

         2.  The  Exchange  Notes  have  been  duly  authorized  for  execution,
authentication  and delivery in exchange  for the Initial  Notes as described in
the Registration Statement.

         The  foregoing  opinions  are  limited  to the  laws  of the  State  of
Maryland, exclusive of securities or "blue sky" laws. We assume no obligation to
supplement  this opinion if any applicable  laws change after the date hereof or
if we become aware of any facts that might change the opinions  expressed herein
after the date  hereof.  We hereby  consent  to the  filing of this  opinion  as
Exhibit 5 to the Registration  Statement and to the reference to our firm in the
Registration Statement.

                                        Very truly yours,

                                        /s/ PIPER & MARBURY L.L.P

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

Ladies and Gentlemen:

         In connection with the registration by Health and Retirement Properties
Trust, a Maryland real estate investment trust (the "Company"),  of $150,000,000
in principal  amount of its 6 3/4% Senior Notes Due 2002, the following  opinion
is furnished to you to be filed with the Securities and Exchange Commission (the
"SEC") as Exhibit 8 to the Company's  Registration  Statement on Form S-4, under
the Securities Act of 1933, as amended (the "Act"),  to be filed on or about the
date hereof (the "Registration Statement").

         We have  acted  as  counsel  for the  Company  in  connection  with the
preparation of the  Registration  Statement,  and we have examined  originals or
copies,  certified or otherwise  identified  to our  satisfaction,  of corporate
records,  certificates and statements of officers and accountants of the Company
and of public officials, and such other documents as we have considered relevant
and  necessary  in  order  to  furnish  the  opinion   hereinafter   set  forth.
Specifically,  and without  limiting the  generality of the  foregoing,  we have
reviewed: (i) the declaration of trust, as amended and restated, and the by-laws
of the Company;  (ii) the  Registration  Statement;  and (iii) the  "Prospectus"
relating to the  Registration  Statement.  We have also reviewed the sections in
the Company's  Annual Report on Form 10-K for the year ended  December 31, 1997,
filed under the  Securities  Exchange  Act of 1934 (the "Form  10-K")  captioned
"Federal Income Tax Considerations" and "ERISA Plans, Keogh Plans and Individual
Retirement  Accounts," as supplemented by the statements in the Prospectus under
the captions  "Prospectus  Summary -- Summary of the Terms of the Exchange Offer
- -- Certain Federal Income Tax  Considerations"  and "Certain  Federal Income Tax
Considerations."  With respect to all  questions of fact on which such  opinions
are based,  we have assumed the accuracy and  completeness of and have relied on
the  information  set forth in the Prospectus and in the documents  incorporated
therein by reference,  and on representations  made to us by the officers of the
Company. We have not independently verified such information; nothing


<PAGE>


Health and Retirement Properties Trust
March 11, 1998
Page 2


has come to our attention,  however,  which would lead us to believe that we are
not entitled to rely on such information.

         The opinion set forth below is based upon the Internal  Revenue Code of
1986,  as  amended,  the  Treasury  Regulations  issued  thereunder,   published
administrative  interpretations  thereof,  and judicial  decisions  with respect
thereto,  all as of the date hereof  (collectively the "Tax Laws"), and upon the
Employee  Retirement Income Security Act of 1974, as amended,  the Department of
Labor regulations issued thereunder,  published  administrative  interpretations
thereof,  and judicial decisions with respect thereto, all as of the date hereof
(collectively, the "ERISA Laws"). No assurance can be given that the Tax Laws or
the ERISA Laws will not change. In preparing the discussions with respect to the
matters  in  the  sections  of the  Form  10-K  captioned  "Federal  Income  Tax
Considerations"  and  "ERISA  Plans,  Keogh  Plans  and  Individual   Retirement
Accounts,"  as  supplemented  by the  statements  in the  Prospectus  under  the
captions  "Prospectus  Summary -- Summary of the Terms of the Exchange  Offer --
Certain  Federal  Income Tax  Considerations"  and "Certain  Federal  Income Tax
Considerations,"   we  have  made  certain  assumptions  and  expressed  certain
conditions and qualifications therein, all of which assumptions,  conditions and
qualifications are incorporated herein by reference.

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

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

                                                Very truly yours,

included therein, filed with the Securities and Exchange Commission.

dated __________,  1998 (the  "Prospectus") of Health and Retirement  Properties
Trust  (the   "Company")  and  this  Letter  of  Transmittal   (the  "Letter  of
Transmittal"),  which  together  constitute  the Company's  offer (the "Exchange
Offer") to exchange $100,000  principal amount (or integral  multiples of $1,000
in excess thereof) of its 6 3/4% Senior Notes due 2002 (the "New Notes"),  which
have  been  registered  under  the  Securities  Act of  1933,  as  amended  (the
"Securities Act"), pursuant to a Registration  Statement of which the Prospectus
is a part, for each $100,000  principal amount (or integral  multiples of $1,000
in excess  thereof) of its  outstanding  6 3/4% Senior  Notes due 2002 (the "Old
Notes"), of which $150,000,000 aggregate principal amount is outstanding.  Other
capitalized  terms used but not defined herein have the meaning given to them in
the Prospectus.

         The Letter of  Transmittal is to be used by Holders of Old Notes (i) if
the Old Notes are to be physically  delivered herewith;  (ii) if delivery of the
Old Notes is made by book-entry  transfer to the Exchange Agent's account at the

Prospectus under "The Exchange Offer--Procedures for Tendering" by any financial
institution  that is a  participant  in DTC and whose name appears on a security
position  listing as the owner of the Old Notes  (unless an Agent's  Message (as
defined in the  Prospectus) is transmitted to and received by the Exchange Agent
on or prior to the  Expiration  Date at one of its addresses set forth above) or
(iii) if the guaranteed delivery  procedures  described in the Prospectus are to
be utilized.
DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE
AGENT.

(i) in whose name Old Notes are  registered  on the books of the  Company or any
other  person  who has  obtained  a  properly  completed  bond  power  from  the

who  desires  to  deliver  such Old Notes by  book-entry  transfer  at DTC.  The
undersigned has completed,  executed and delivered this Letter of Transmittal to

To: State Street Bank and Trust Company


Ladies and Gentlemen:

         Subject  to the  terms  and  conditions  of  the  Exchange  Offer,  the
undersigned  hereby  tenders to the  Company the  principal  amount of Old Notes
indicated  above.  Subject to and effective  upon the acceptance for exchange of
the principal  amount of Old Notes  tendered in  accordance  with this Letter of
Transmittal,  the undersigned sells, assigns and transfers to, or upon the order
of, the Company all right,  title and interest in and to the Old Notes  tendered
hereby. The undersigned hereby irrevocably constitutes and appoints the Exchange
Agent its agent and  attorney-in-fact  (with full  knowledge  that the  Exchange
Agent also acts as the agent of the  Company)  with  respect to the tendered Old
Notes  with full  power of  substitution  to (i)  deliver  such Old Notes to the
Company or transfer  ownership of such Old Notes on the account books maintained
by DTC, in each case,  together with all accompanying  evidences of transfer and
authenticity to, or upon the order of, the Company,  (ii) present such Old Notes
or transfer  ownership of such Old Notes on the account books maintained by DTC,
for  transfer  on the books of the Company and (iii)  receive all  benefits  and
otherwise exercise all rights of beneficial  ownership of such Old Notes, all in
accordance with the terms of the Exchange Offer.  The power of attorney  granted
in this paragraph shall be deemed irrevocable and coupled with an interest.

         The undersigned  hereby represents and warrants that he or she has full
power and authority to tender,  sell, assign and transfer the Old Notes tendered
hereby and that the Company will acquire good and  unencumbered  title  thereto,
free and clear of all liens,  restrictions,  charges  and  encumbrances  and not
subject to any adverse  claim,  when the same are acquired by the  Company.  The
undersigned  hereby  acknowledges  that  this  Exchange  Offer is being  made in
reliance  upon an  interpretation  by the staff of the  Securities  and Exchange
Commission that any New Notes acquired in exchange for Old Notes tendered hereby
may be offered for sale,  resold and otherwise  transferred  by holders  thereof
(other than any such Holder that is an  "affiliate" of the Company or any of its
subsidiaries  within the  meaning of Rule 405 under the  Securities  Act of 1933
(the "Securities Act")), without compliance with the registration and prospectus
delivery  provisions  of the  Securities  Act,  provided that such New Notes are
acquired in the  ordinary  course of business of the Holder  receiving  such New
Notes and that neither the Holder nor any such other  person has an  arrangement
with any  person to  participate  in the  distribution  of such New  Notes.  The
undersigned  hereby further  represents that (i) the New Notes acquired pursuant
to the Exchange Offer are being obtained in the ordinary course of such Holder's
business, (ii) such Holder has no arrangements with any person to participate in
the  distribution  (within the meaning of the Securities  Act) of such New Notes
and (iii) such Holder is not an  "affiliate,"  as defined  under Rule 405 of the
Securities Act of the Company or any of its  subsidiaries  or, if such Holder is
an affiliate,  that such Holder will comply with the registration and prospectus
delivery  requirements  of the Securities Act to the extent  applicable.  If the
undersigned is not a  broker-dealer,  the undersigned  represents that it is not
engaged in, and does not intend to engage in, a  distribution  of New Notes.  If
the  undersigned  is a  broker-dealer  that will  receive  New Notes for its own
account  in  exchange  for Old  Notes,  it  represents  that the Old Notes to be
exchanged  for the New Notes were  acquired  by it as a result of  market-making
activities or other trading  activities and acknowledges  that it will deliver a
prospectus  in  connection  with any  resale of such New Notes;  however,  by so
acknowledging and by delivering a prospectus, the undersigned will not be deemed
to admit that it is an  "underwriter"  within the meaning of the Securities Act.
The undersigned will, upon request, execute and deliver any additional documents
deemed by the  Exchange  Agent or the Company to be  necessary  or  desirable to
complete the assignment, transfer and purchase of the Old Notes tendered hereby.

         For purposes of the Exchange Offer, the Company shall be deemed to have
accepted validly tendered Old Notes,  when, as and if the Company has given oral
or written notice of acceptance thereof to the Exchange Agent.

         If any tendered Old Notes are not accepted for exchange pursuant to the
Exchange  Offer for any reason,  any such  unaccepted Old Notes will be returned
(except as noted below with respect to tenders through DTC), without expense, to
the  undersigned at the address shown below or at a different  address as may be
indicated herein under "Special Payment Instructions" as promptly as practicable
after the Expiration Date.

         All authority herein conferred or agreed to be conferred in this Letter
of  Transmittal  shall  survive  the death,  incapacity  or  dissolution  of the
undersigned,  and any obligation of the  undersigned  hereunder shall be binding
upon the administrators, legal representatives, heirs, personal representatives,
successors and assigns of the undersigned.

         The undersigned  understands  that tenders of Old Notes pursuant to the
procedures  described  under the caption  "The  Exchange  Offer--Procedures  for
Tendering" in the Prospectus and in the  instructions  hereto will  constitute a
binding  agreement  between the  undersigned  and the Company upon the terms and

by credit to the account at DTC).  Similarly,  unless otherwise  indicated under
"Special  Delivery  Instructions,"  please send the New Notes issued in exchange
for the Old Notes  accepted  for  exchange and any Old Notes not tendered or not
exchanged (and accompanying documents, as appropriate) to the undersigned at the

tender is being  made  through  DTC.  In the event  that both  "Special  Payment
Instructions"  and "Special Delivery  Instructions" are completed,  please issue
the New Notes  issued in exchange  for the Old Notes  accepted  for exchange and
return any Old Notes not  tendered or not  exchanged in the name(s) of, and send
said New Notes to, the person(s) so indicated.  The undersigned  recognizes that
the Company has no obligation pursuant to the "Special Payment Instructions" and
"Special  Delivery  Instructions" to transfer any Old Notes from the name of the
registered  holder(s) thereof if the Company does not accept for exchange any of
the Old Notes so tendered.

         1. Delivery of this Letter of Transmittal  and Old Notes.  The tendered
Old Notes (or a confirmation of a book-entry  transfer into the Exchange Agent's
account at DTC of all Old Notes delivered electronically), as well as a properly
completed  and duly  executed  copy of this Letter of  Transmittal  or facsimile
hereof and any other documents  required by this Letter of Transmittal,  must be
received by the  Exchange  Agent at its address set forth  herein  prior to 5:00
p.m., New York City time, on the Expiration  Date. The method of delivery of the
tendered Old Notes, this Letter of Transmittal and all other required  documents
to the Exchange  Agent is at the election and risk of the Holder and,  except as
otherwise  provided  below,  the delivery will be deemed made only when actually
received by the Exchange  Agent.  Instead of delivery by mail, it is recommended
that the  Holder  use an  overnight  or hand  delivery  service.  In all  cases,
sufficient  time  should be  allowed  to assure  timely  delivery.  No Letter of
Transmittal or Old Notes should be sent to the Company.

         Holders who wish to tender  their Old Notes and (i) whose Old Notes are
not  immediately  available,  or (ii) who cannot  deliver their Old Notes,  this
Letter of Transmittal  or any other  documents  required  hereby to the Exchange
Agent  prior to 5:00 p.m.,  New York City time,  on the  Expiration  Date,  must
tender their Old Notes according to the guaranteed delivery procedures set forth
in the Prospectus.  Pursuant to such procedures: (i) such tender must be made by
or through a member firm of a registered  national securities exchange or of the
National Association of Securities Dealers,  Inc., or a commercial bank or trust
company having an office or  correspondent  in the United States or an "eligible
guarantor  institution" (an "Eligible  Institution")  within the meaning of Rule
17Ad-15 under the Securities Exchange Act of 1934, as amended; (ii) prior to the
Expiration  Date,  the  Exchange  Agent  must have  received  from the  Eligible
Institution a properly completed and duly executed Notice of Guaranteed Delivery
(by facsimile  transmission,  mail or hand delivery)  setting forth the name and
address  of the Holder of the Old Notes,  the  certificate  number or numbers of
such Old Notes and the principal amount of Old Notes tendered,  stating that the
tender is being made thereby and guaranteeing  that,  within three business days
after the  Expiration  Date,  this Letter of Transmittal  (or facsimile  hereof)
together  with the Old  Notes  (or a  confirmation  of  electronic  delivery  of
book-entry  delivery  into the  Exchange  Agent's  account at DTC) and any other
required  documents  will be  deposited  by the  Eligible  Institution  with the
Exchange  Agent;  and (iii)  such  properly  completed  and  executed  Letter of
Transmittal (or facsimile  hereof),  as well as all other documents  required by
this  Letter of  Transmittal  and all  tendered  Old  Notes in  proper  form for
transfer (or a confirmation of electronic  delivery of book-entry  delivery into
the Exchange  Agent's  account at DTC),  must be received by the Exchange  Agent
within three  business days after the  Expiration  Date,  all as provided in the
Prospectus  under  the  caption  "The  Exchange  Offer  --  Guaranteed  Delivery
Procedures."  Any  Holder of Old Notes who wishes to tender his or her Old Notes
pursuant to the guaranteed delivery procedures  described above must ensure that
the Exchange  Agent  receives the Notice of  Guaranteed  Delivery  prior to 5:00
p.m., New York City time, on the Expiration  Date.  Upon request of the Exchange
Agent,  a Notice of  Guaranteed  Delivery  will be sent to  Holders  who wish to
tender their Old Notes according to the guaranteed delivery procedures set forth
above.

         All questions as to the validity,  form, eligibility (including time of
receipt) and  acceptance  of tendered Old Notes and  withdrawal  of tendered Old
Notes  will  be  determined  by  the  Company  in  its  sole  discretion,  which
determination will be final and binding. The Company reserves the absolute right
to  reject  any and all Old  Notes not  properly  tendered  or any Old Notes the
Company's  acceptance of which would, in the opinion of counsel for the Company,
be  unlawful.  The  Company  also  reserves  the right to waive any  defects  or
irregularities  or  conditions  of  tender  as  to  the  Exchange  Offer  and/or
particular Old Notes. The Company's  interpretation  of the terms and conditions
of the Exchange Offer (including the instructions in this Letter of Transmittal)
shall be final and  binding  on all  parties.  Unless  waived,  any  defects  or
irregularities in connection with tenders of Old Notes must be cured within such
time as the Company shall determine. Neither the Company, the Exchange Agent nor
any other  person  shall be under any duty to give  notification  of  defects or
irregularities with respect to tenders of Old Notes, nor shall any of them incur
any liability for failure to give such  notification.  Tenders of Old Notes will
not be deemed to have been made until such defects or  irregularities  have been
cured or waived. Any Old Notes received by the

Exchange  Agent that are not  validly  tendered  and as to which the  defects or
irregularities  have not been cured or waived will be  returned by the  Exchange
Agent to the tendering Holders of Old Notes,  unless otherwise  provided in this
Letter of Transmittal, as soon as practicable following the Expiration Date.

         2.  Partial  Tenders.  Tenders  of Old Notes will be  accepted  only in
denominations  of  $100,000  and any  integral  multiples  of  $1,000  in excess
thereof.  If less than the entire principal amount of any Old Notes is tendered,
the tendering  Holder should fill in the principal amount tendered in the fourth
column of the box  entitled  "Description  of 6 3/4% Senior  Notes Due 2002 (Old
Notes)"  above.  The  entire  principal  amount  of Old Notes  delivered  to the
Exchange Agent will be deemed to have been tendered unless otherwise  indicated.
If the entire principal amount of all Old Notes is not tendered,  then Old Notes
for the  principal  amount of Old Notes not tendered and the New Notes issued in
exchange  for any Old Notes  accepted  will be sent to the  Holder at his or her
registered  address,  unless a different  address is provided in the appropriate
box on this Letter of Transmittal, promptly after the Old Notes are accepted for
exchange.

         3.   Signatures  on  the  Letter  of   Transmittal;   Bond  Powers  and
Endorsements;  Guarantee  of  Signatures.  If this  Letter  of  Transmittal  (or
facsimile  hereof) is signed by the record  Holder(s) of the Old Notes  tendered
hereby, the signature must correspond with the name(s) as written on the face of
the Old Notes without alteration, enlargement or any change whatsoever.

         If this Letter of  Transmittal  (or facsimile  hereof) is signed by the
registered  Holder or Holders of Old Notes  tendered and the New Notes issued in
exchange  therefor are to be issued (or any untendered  principal  amount of Old
Notes is to be reissued) to the registered  Holder, the said Holder need not and
should not endorse any tendered Old Notes, nor provide a separate bond power.

         If this  Letter of  Transmittal  (or  facsimile  hereof) is signed by a
person other than the registered Holder or Holders of any Old Notes listed, such
Old Notes must be endorsed or accompanied  by appropriate  bond powers signed as
the name of the registered Holder or Holders appears on the Old Notes.

         If this Letter of Transmittal (or facsimile hereof) or any Old Notes or
bond  powers  are  signed by  trustees,  executors,  administrators,  guardians,
attorneys-in-fact or officers of corporations or others acting in a fiduciary or
representative  capacity,  such persons  should so indicate when  signing,  and,
unless  waived by the  Company,  evidence  satisfactory  to the Company of their
authority so to act must be submitted with this Letter of Transmittal.

         Endorsements on Old Notes or signatures on bond powers required by this
Instruction 3 must be guaranteed by an Eligible  Institution  participating in a
recognized medallion signature guarantee program.

         Except as otherwise  provided  below,  all signatures on this Letter of
Transmittal (or facsimile hereof) must be guaranteed by an Eligible  Institution
participating in a recognized medallion signature guarantee program.  Signatures
on this  Letter of  Transmittal  need not be  guaranteed  if (i) this  Letter of
Transmittal  is signed by the  registered  Holder(s)  of the Old Notes  tendered
herewith  (including  any  participant  in DTC whose name  appears on a security
position  listing  as the  owner  of Old  Notes)  and  such  Holder(s)  have not
completed the box set forth herein entitled "Special  Payments  Instructions" or
the box  entitled  "Special  Delivery  Instructions"  or (ii) such Old Notes are
tendered for the account of an Eligible Institution.

         4. Special Issuance and Delivery Instructions. Tendering Holders should
indicate,  in the  applicable  box or boxes,  the name and  address to which New
Notes or substitute Old Notes for principal amounts not tendered or not accepted
for exchange are to be issued or sent, if different from the name and address of
the person signing this Letter of  Transmittal  (or in the case of tender of the
Old Notes  through  DTC, if  different  from DTC).  In the case of issuance in a
different  name, the taxpayer  identification  or social  security number of the
person named must also be indicated.

         5. Tax  Identification  Number.  Federal income tax law requires that a
Holder  whose  offered Old Notes are  accepted  for  exchange  must  provide the
Company (as payor) with his, her or its correct Taxpayer Identification

                                        9

<PAGE>



Number ("TIN"), which, in the case of an exchanging Holder who is an individual,
is his or her social  security  number.  If the Company is not provided with the
correct TIN or an adequate basis for exemption,  such Holder may be subject to a
$50 penalty imposed by the Internal  Revenue  Service (the "IRS").  In addition,
delivery to such Holder of New Notes may be subject to backup  withholding in an
amount equal to 31% of the gross proceeds  resulting from the Exchange Offer. If
withholding results in an overpayment of taxes, a refund may be obtained. Exempt
Holders   (including,   among  others,  all  corporations  and  certain  foreign
individuals)  are  not  subject  to  these  backup   withholding  and  reporting
requirements.

         To prevent backup withholding, each exchanging Holder must provide his,
her or its correct TIN by completing the Substitute Form W-9 enclosed  herewith,
certifying  that the TIN  provided is correct (or that such Holder is awaiting a
TIN) and that either (i) the Holder is exempt from backup withholding,  (ii) the
Holder has not been  notified by the IRS that he, she or it is subject to backup
withholding  as a result of a failure to report all  interest or  dividends,  or
(iii) the IRS has notified the Holder that he, she or it is no longer subject to
backup  withholding.  In order to  satisfy  the  Exchange  Agent  that a foreign
individual qualifies as an exempt recipient, such Holder must submit a statement
signed under penalty of perjury attesting to such exempt status. Such statements
may be obtained from the Exchange  Agent.  If the Old Notes are in more than one
name or are not in the name of the actual owner, consult the Substitute Form W-9
for  information  on which TIN to report.  If you do not provide your TIN to the
Company  within 60 days,  backup  withholding  will begin and continue until you
furnish your TIN to the Company.

         6. Transfer  Taxes.  The Company will pay all transfer  taxes,  if any,
applicable  to the  exchange of Old Notes  pursuant to the Exchange  Offer.  If,
however,  New Notes or Old Notes for principal  amounts not tendered or accepted
for exchange are to be delivered  to, or are to be  registered  or issued in the
name of, any person other than the  registered  Holder of the Old Notes tendered
hereby,  or if tendered Old Notes are registered in the name of any person other
than the person  signing  this Letter of  Transmittal,  or if a transfer  tax is
imposed  for any reason  other than the  exchange  of Old Notes  pursuant to the
Exchange Offer,  then the amount of any such transfer taxes (whether  imposed on
the  registered  Holder or on any other person) will be payable by the tendering
Holder.

         Except as provided in this  Instruction 6, it will not be necessary for
transfer  tax  stamps to be affixed  to the Old Notes  listed in this  Letter of
Transmittal.

         7. Waiver of  Conditions.  The Company  reserves the absolute  right to
amend, waive or modify specified conditions in the Exchange Offer in the case of
any Old Notes tendered.

         8. Mutilated,  Lost Stolen or Destroyed Old Notes. Any tendering Holder
whose Old Notes have been mutilated,  lost,  stolen or destroyed  should contact
the Exchange Agent at the address indicated herein for further instructions.

         9. Requests for Assistance or Additional Copies. Questions and requests
for  assistance  and requests for  additional  copies of the  Prospectus or this
Letter of  Transmittal  may be  directed  to the  Exchange  Agent at the address
specified  above. The telephone number for the Exchange Agent is (617) 664-5590.
Holders may also contact their broker, dealer, commercial bank, trust company or
other nominee for assistance concerning the Exchange Offer.
