(including the states and the District of Columbia), its territories, its

                  "United States person" means, unless otherwise specified with
respect to any Securities pursuant to Section 301, an individual who is a

                  SECTION 102. Compliance Certificates and Opinions. Upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee an
Officers Certificate stating that all conditions precedent, if any, provided
for in this Indenture relating to the proposed action have been complied with
and an Opinion of Counsel stating that in the opinion of such counsel all such
conditions precedent, if any, have been complied with, except that in the case
of any such application or request as to which the furnishing of such documents
is specifically required by any provision of this Indenture relating to such
particular application or request, no additional certificate or opinion need be
furnished.

                  Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (including certificates
delivered pursuant to Section 1010) shall include:

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

                  (2) a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in
such certificate or opinion are based;

                  (3) a statement that, in the opinion of each such individual,
he has made such examination or investigation as is necessary to enable him to
express an informed opinion as to whether or not such condition or covenant has

                                      -12-



   19



                  (4) a statement as to whether, in the opinion of each such
individual, such condition or covenant has been complied with.

                  SECTION 103. Form of Documents Delivered to Trustee. In any
case where 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 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 or 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 stating that the information as to such factual matters is in the
possession of the Company, 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 any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Company and any agent of the Trustee or the Company, if made in

                                      -13-



   20



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

                                      -14-



   21



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 other Act
of Holders or other document provided or permitted by this Indenture to be made
upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, 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, 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 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

                                      -15-

   22



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 be binding on their 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, 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. Non-Recourse. Notwithstanding anything contained herein to
the contrary, no recourse under or upon any obligation, covenant or agreement
contained in this Indenture, in any Security or coupon appertaining thereto, or
because of any indebtedness evidenced thereby (including, without limitation,
any obligation or indebtedness relating to the


                                      -16-




   23



principal of, or premium or Make-Whole Amount, if any, interest or any other
amounts due, or claimed to be due, on any Security issued hereunder), or for any
claim based thereon or otherwise in respect thereof, shall be had (i) against
the Trust or any other partner in the Company, (ii) against any Person which
owns an interest, directly or indirectly, in any partner in the Company or (iii)
against any promoter, as such, or against any past, present or future
shareholder, officer, director or partner, as such, of the Company, the Trust or
of any successor, either directly or through the Company, the Trust or any
successor, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the Holders thereof and as part of the
consideration for the issue of the Securities. The Holders of the Securities
hereunder acknowledge by the acceptance of the Securities that their sole
remedies under this Indenture for any Default by the Company in the payment of
the principal of, or any premium or Make-Whole Amount, if any, interest or any
amounts due, or claimed to be due, on any Security, or otherwise, are limited to
claims against the property of the Company as provided in Section 503 hereof.

         SECTION 112. Governing Law. This Indenture and the Securities and
coupons shall be governed by and construed in accordance with the law of the
State of New York. 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 113. 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) 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.

                                   ARTICLE TWO

                                SECURITIES FORMS

         SECTION 201. Forms of Securities. The Registered Securities, if any, of
each series and the Bearer Securities, if any, of each series and related
coupons shall be in substantially the forms as shall be established in one or
more indentures supplemental hereto or approved from time to time by or pursuant
to a Board Resolution in accordance with this Indenture, shall have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements placed thereon as the Company may
deem appropriate and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any


                                      -17-




   24



rule or regulation made pursuant thereto or with any rule or regulation of any
stock exchange on which the Securities may be listed, or to conform to usage.

         Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have interest coupons attached.

         The definitive Securities and coupons shall be printed, lithographed or
engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or may be produced in any other manner, all as
determined by the officers executing such Securities or coupons, as evidenced by
their execution of such Securities or coupons.

         SECTION 202. Form of Trustee's Certificate of Authentication. Subject
to Section 611, the Trustee's certificate of authentication shall be
insubstantially the following form:

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

                           The First National Bank of Chicago, as Trustee

                           By:
                              -------------------------------------------
                              Authorized Signatory

         SECTION 203. Securities Issuable in Global Form. If Securities of or
within a series are issuable in global form, as specified as contemplated by
Section 301, then, notwithstanding clause (8) of Section 301 and the provisions
of Section 302, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
shall represent the aggregate amount of Outstanding Securities of such series
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities of such series represented thereby may from time to time be increased
or decreased to reflect exchanges. Any endorsement of a Security in global form
to reflect the amount, or any increase or decrease in the amount, of Outstanding
Securities represented thereby shall be made by the Trustee in such manner and
upon instructions given by such Person or Persons as shall be specified therein
or in the Company Order to be delivered to the Trustee pursuant to Section 303
or 304. Subject to the provisions of Section 303 and, if applicable, Section
304, the Trustee shall deliver and redeliver any Security in permanent global
form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Company Order. If a Company Order
pursuant to Section 303 or 304 has been, or simultaneously is, delivered, any
instructions by the Company with respect to endorsement or delivery or
redelivery of a Security in global form shall be in writing but need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
security in global form together with


                                      -18-




   25



written instructions (which need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel) with regard to the reduction in the
principal amount of Securities represented thereby, together with the written
statement contemplated by the last sentence of Section 303.

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

         Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a permanent
global Security in bearer form, Euroclear and/or CEDEL.

         (15) any deletions from, modifications of or additions to the Events of
Default or covenants of the Company 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;

series shall be payable, if other than the Person in whose name that Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, the manner in which, or the Person
to whom, any interest on any Bearer Security of the series shall be payable, if
otherwise than upon presentation and surrender of the coupons appertaining
thereto as they severally mature, and the extent to which, or the manner in
which, any interest payable on a temporary global Security on an Interest
Payment Date will be paid if other than in the manner provided in Section 304;


                                      -21-




   28



         (19) the applicability, if any, of Sections 1402 and/or 1403 to the
Securities of the series and any provisions in modification of, in addition to
or in lieu of any of the provisions of Article Fourteen;

         (20) 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;

         (21) 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;

         (22) whether and under what circumstances the Company will pay
Additional Amounts as contemplated by Section 1011 on the Securities of the
series to any Holder who is not a United States person (including any

         (25) 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 denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such 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 on behalf 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 with respect to the Securities of any series, the
Registered Securities of such series, other than Registered Securities issued in
global form (which may be of any denomination), shall be


                                      -22-




   29



issuable in denominations of $1,000 and any integral multiple thereof and the
Bearer Securities of such series, other than Bearer Securities issued in global
form (which may be of any denomination), shall be issuable in a denomination of
$5,000.

         SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed by the
Chairman of the Board, and President or one of the Executive Vice Presidents,
and the Chief Financial Officer of the Trust, as general partner of the Company.
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 Trust 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
and 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 to Euroclear or CEDEL, as the case
may be, 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


                                      -23-




   30



Securities, the Trustee shall be entitled to receive, and (subject to TIA
Section 315(a) through 315(d)) shall be fully protected in relying upon,

              (i)  an Opinion of Counsel complying with Section 102 and 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 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.

         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 signatory, and such


                                      -24-




   31



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 The
Depository Trust Company. 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


                                      -25-




   32



"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 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 form 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


                                      -26-




   33



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 the 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.

         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


                                      -27-




   34



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 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 Exchange Act if so required by applicable law or regulation, the Company


                                      -28-




   35



shall appoint a successor depositary with respect to such global Security or
Securities. If (x) a successor depositary for such global Security or Securities
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such unwillingness, inability or ineligibility, (y)
an Event of Default has occurred and is continuing and the beneficial owners
representing a majority in principal amount of the applicable series of
Securities represented by such global Security or Securities advise DTC to cease
acting as depositary for such global Security or Securities or (z) the Company,
in its sole discretion, determines at any time that all Outstanding Securities
(but not less than all) of any series issued or issuable in the form of one or
more global Securities shall no longer be represented by such global Security or
Securities, then the Company shall execute, and the Trustee shall authenticate
and deliver definitive Securities of like series, rank, tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of such global Security or Securities. If any beneficial owner of an interest in
a permanent global Security is otherwise entitled to exchange such interest for
Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent global
Security shall have been given, then without unnecessary delay but in any event
not 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 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
of 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


                                      -29-




   36



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 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 the portion, if any, of such Security not to be so repaid.

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

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of 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.


                                      -30-




   37



         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 or
Make-Whole Amount, 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


                                      -31-




   38



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 its participants for the benefit of the beneficial owners
thereof.

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

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

         (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Registered Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each Registered
Security of such series and the date of the proposed payment (which shall not be
less than 20 days after such notice is received by the Trustee), and at the same
time the Company shall deposit with the Trustee an amount of money in the
currency or currencies, currency unit or units or composite currency or
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
on or prior to the date of the proposed payment, such money when deposited to be
held in trust for the benefit of the Persons entitled to such Defaulted Interest
as in this clause provided. Thereupon the Trustee shall fix a Special Record
Date for the payment of such Defaulted Interest which shall be not 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


                                      -32-




   39



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 at the office or agency in a Place
of Payment for such series in exchange for a Registered Security of 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 or Make-Whole Amount, 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 be
overdue, and none of the Company, the Trustee or 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 be overdue, and none of the Company, the
Trustee or 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.


                                      -33-




   40



         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, its participants 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 the Company Order, the
Company directs their return to it.

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

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

         SECTION 401. Satisfaction and Discharge of Indenture. This Indenture
shall upon Company Request cease to be of further effect with respect to any
series of Securities specified in such Company Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for and any right to receive Additional
Amounts, as provided in Section 1011), and the Trustee, upon receipt of a
Company Order, and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series when,

         (1) either

                  (A) all Securities of such series theretofore authenticated
and delivered and all coupons, if any, appertaining thereto (other than (i)
coupons appertaining to Bearer


                                      -34-




   41



Securities surrendered for exchange for Registered Securities and maturing after
such exchange, whose surrender is not required or has been waived as provided in
Section 305, (ii) Securities and coupons of such series which have been
destroyed, lost or stolen and which have been replaced or paid as provided in
Section 306, (iii) coupons appertaining to Securities called for redemption and
maturing after the relevant Redemption Date, whose surrender has been waived as
provided in Section 1106, and (iv) Securities and coupons of such series for
whose payment money has theretofore been deposited in trust or segregated and
held in trust by the Company and thereafter repaid to the Company or discharged
from such trust, as provided in Section 1003) have been delivered to 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

               (i)   have become due and payable, or

               (ii)  will become due and payable at their Stated Maturity within
one year, or

               (iii) if redeemable at the option of the Company, are to be
called for redemption within one 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 trust funds in trust for the 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 or
Make-Whole Amount, 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. Notwithstanding the satisfaction and
discharge of this Indenture, 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.

          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


                                      -35-




   42



thereto, of the principal (and premium or Make-Whole Amount, if any), and any
interest and Additional Amounts for whose payment such money has deposited with
or received by the Trustee, but such money need not be segregated from other
funds except to the extent required by law.

                                  ARTICLE FIVE

                                    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 or
Make-Whole Amount, if any, on) any Security of that series when it becomes due
and payable at its Maturity; or

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

         (4) default in the performance, or breach, of any covenant or warranty
of the Company in this Indenture with respect to any Security of that series
(other than a covenant or warranty a default in whose performance or whose
breach is elsewhere in this Section specifically dealt with), 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 25% 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 on a full recourse basis)
whether such indebtedness now exists or shall hereafter be created, which
default shall constitute a failure to pay an aggregate principal amount
exceeding $10,000,000 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
$10,000,000 becoming or being declared due and payable prior to the date on
which it


                                      -36-




   43



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 10% in principal amount of the Outstanding Securities
of that series, a written notice specifying such default and requiring the
Company to cause such indebtedness to be discharged or cause such acceleration
to be rescinded or annulled and stating that such notice is a "Notice of
Default" hereunder; or

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

                (A) commences a voluntary case,

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

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

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

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

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

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

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

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

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

         SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing (other than an Event of Default specified
in clause (6) or (7) of Section 501 that occurs with respect to the Company),
then and in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of that series may declare the
principal of (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), and premium


                                      -37-




   44



(if any) and accrued interest on, 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, premium
(if any), and accrued interest or specified portion thereof shall become
immediately due and payable. In the event of a declaration of acceleration
because an Event of Default set forth in clause (5) of Section 501 has occurred
and is continuing, such declaration of acceleration shall be automatically
rescinded and annulled if the event of default triggering such Event of Default
pursuant to clause (5) along with any other events of default that have been
triggered by the Event of Default (whether or not a notice or declaration of
acceleration shall have been given by the holders of the relevant indebtedness)
shall be remedied or cured by the Company and/or the relevant Subsidiary or
waived by the holders of the relevant indebtedness within 60 days after the
declaration of acceleration with respect thereto. If an Event of Default
specified in clause (6) or (7) of Section 501 occurs with respect to the
Company, the principal of (or specified portion thereof), premium, if any, and
accrued interest on the Securities of all series then outstanding shall ipso
facto become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Holder.

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

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

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

         (2) all Events of Default with respect to Securities of that series,
other than the nonpayment of the principal of (or premium or Make-Whole Amount,
if any) or interest on


                                      -38-




   45



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 or
Make-Whole Amount, 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 or Make-Whole Amount, if any) and interest and Additional Amount, with
interest upon any overdue principal (and premium or Make-Whole Amount, if any)
and, to the extent that payment of such interest shall be legally enforceable,
upon any overdue installments of interest or Additional Amounts, 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


                                      -39-




   46



have made any demand on the Company for the payment of overdue principal,
premium or Make-Whole Amount, if any, or interest) 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 or Make-Whole Amount, if any) and interest and Additional
Amounts, if any, owing and unpaid in respect of the Securities and to file such
other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and
of the Holders allowed in such judicial proceeding, and

                (ii) to collect and receive any moneys or other property payable
or deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator (or other similar
official) in any such judicial proceeding is hereby authorized by each Holder of
Securities of such series and coupons to make such payments to the Trustee, and
in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee and
any predecessor Trustee, their agents and counsel, and any other amounts due the
Trustee or any predecessor Trustee under Section 606. Nothing herein contained
shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any Holder of a Security or coupon any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or coupons or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder of a Security or coupon in any such
proceeding.

         SECTION 505. Trustee May Enforce Claims Without Possession of
Securities or Coupons. All rights of action and claims under this Indenture or
any of the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or coupons or the production
thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, be for the ratable benefit of the Holders of the
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 or Make-Whole Amount, if any) or
interest and any Additional Amounts, upon presentation of the Securities or
coupons, or both, as the case may be, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

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


                                      -40-




   47



                SECOND: To the payment of the amounts then due and unpaid upon
the Securities and coupons for principal (and premium or Make-Whole Amount, 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 or Make-Whole Amount, 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 25% 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 indemnity
reasonably satisfactory to the Trustee against the costs, expenses and
liabilities to be incurred in compliance with such request;

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

         (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series; it being
understood and intended that no one or more of such Holders shall have any right
in any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other of such
Holders, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all such
Holders.

         SECTION 508. Unconditional Right of Holders to Receive Principal,
Premium or Make-Whole Amount, 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 or Make-Whole Amount, 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.


                                      -41-




   48



         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 involve it in
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


                                      -42-




   49



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

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

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

         SECTION 514. Waiver of Usury, Stay or Extension Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully 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 any 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 10% 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 or Make-Whole Amount,
if any) or interest on any Security on or after the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on or after the
Redemption Date).

                                   ARTICLE SIX

                                   THE TRUSTEE

         SECTION 601. Notice of Defaults. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
shall transmit in the manner and to the extent provided in TIA Section 313(c),
notice of such default hereunder


                                      -43-




   50



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 or Make-Whole Amount, if any) or interest on or any
Additional Amounts with respect to any Security of such series, or in the
payment of any 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 interests 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
Trustees may be sufficiently evidenced by a Board Resolution;

         (3) whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting 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
security or indemnity reasonably satisfactory to the Trustee 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


                                      -44-




   51



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, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

         Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee. In case an Event of Default with respect to the
Securities has occurred (which has not been cured or waived) the Trustee shall
exercise with respect to the Securities such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

         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, coupons, or any prospectus pursuant to which the Securities are
offered 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 any 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 the 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.


                                      -45-




   52



         SECTION 606. Compensation and Reimbursement. The Company agrees:

         (1) to pay to the Trustee from time to time reasonable compensation for
all services rendered by it hereunder as mutually agreed upon (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, its directors, officers and
employees, 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 or Make-Whole Amount, if
any) or interest on particular Securities or any 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.


                                      -46-




   53



                (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 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

                    (2) the Trustee shall cease to be eligible under Section 607
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 cause
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 or such appointment, become the successor Trustee
with respect to the Securities of such series and to


                                      -47-




   54



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, the resigning or removed Trustee
or 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 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, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee, and shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder, subject nevertheless to its
claim, if any, provided for in Section 606.

                (b) In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental
hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall
accept such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co- trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor


                                      -48-




   55



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 Authenticating 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 shall at all
times be a


                                      -49-




   56



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 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 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.

                                    as Trustee

                                    By: 
                                       ----------------------------------------
                                               as Authorized Signatory


                                  ARTICLE SIX A

                            SUBORDINATION; SENIORITY

         SECTION 601A. Securities Subordinated to Senior Indebtedness.

                (a) The Issuer agrees, and each Holder of the Securities of any
series by his acceptance thereof likewise agrees, that the payment of the
principal of and Interest on the Securities (all of the foregoing, a "Payment or
Distribution") is subordinated and junior in right of payment, to the extent and
in the manner provided in this Article Six A, except as provided in Section 402,
to the prior payment in full in cash of all Senior Indebtedness whether
outstanding on the date hereof or hereafter created, incurred, assumed or
guarantied.

                A Payment or Distribution shall include any asset of any kind or
character, and may consist of cash, securities or other property, by setoff or
otherwise, and shall include, without limitation, any purchase, redemption or
other acquisition of the Securities or the making of any deposit of funds or
securities pursuant to this Indenture (including, without limitation, any
deposit pursuant to Article Five hereof).

                (b) The Senior Indebtedness of the Issuer shall continue to be
Senior Indebtedness and entitled to the benefit of these subordination
provisions irrespective of any amendment, modification or waiver of any term of
any instrument relating to the Senior Indebtedness or the extension or renewal
or refinancing of the Senior Indebtedness.

                (c) All the provisions of this Indenture and the Securities
shall be subject to the provisions of this Article Six A so far as they may be
applicable thereto, except that nothing in this Article Six A shall apply to
claims for, or payments to, the Trustee under or pursuant to Section 606.

                (d) No right of any holder of any Senior Indebtedness to enforce
subordination as herein provided shall at any time or in any way be affected or
impaired by any failure to act on the part of the Issuer, any Paying Agent, the
Holders of the Securities, the Trustee or the holders of the Senior
Indebtedness, or by any noncompliance by the Issuer, any Paying Agent, the
Holders of the Securities or the Trustee with any of the terms, provisions and
covenants of the Securities or this Indenture, regardless of any knowledge
thereof that any such holder of Senior Indebtedness may have or be otherwise
charged with.

   58



                (e) In the event that the Securities are declared due and
payable before their expressed maturity because of the occurrence of a default
hereunder, the Issuer will give prompt notice in writing of such happening to
the holders of Senior Indebtedness.

         SECTION 602A. Issuer Not to Make Payments with Respect to Securities in
Certain Circumstances. No Payment or Distribution shall be made by the Issuer on
account of a principal of or Interest on the Securities, whether upon stated
maturity, upon redemption or acceleration, or otherwise, or on account of the
purchase or other acquisition of Securities, whether upon stated maturity, upon
redemption or acceleration, or otherwise, if there shall have occurred and be
continuing a default with respect to any Senior Indebtedness which, with notice
or the passage of time or both, would permit the acceleration thereof, and (a)
such default is the subject of a judicial proceeding or (b) notice of such
default in writing or by telegram has been given to the Issuer by any holder or
holders of any Senior Indebtedness, unless and until the Issuer shall have
received written notice from such holder or holders that such default or event
of default shall have been cured or waived or shall have ceased to exist.

         Upon any acceleration of the principal of the Securities or any payment
by the Issuer, or distribution of assets of the Issuer of any kind or character,
whether in cash, property or securities, to creditors upon any dissolution or
winding up or liquidation or reorganization of the Issuer, whether voluntary or
involuntary, or in bankruptcy, insolvency, receivership or other proceedings,
all amounts due or to become due upon all Senior Indebtedness shall first be
paid in full in cash, or payment thereof provided for to the satisfaction of the
holders thereof, before any Payment or Distribution is made on account of the
redemption price or principal of or Interest on the Securities; and (subject to
the power of a court of competent jurisdiction to make other equitable
provision, which shall a have been determined by such court to give effect to
the rights conferred in this Article Six A upon the Senior Indebtedness and the
holders thereof with respect to the Securities or the Holders thereof or the
Trustee, by a lawful plan of reorganization or readjustment under applicable
law) upon any such dissolution or winding up or liquidation or reorganization,
any Payment or Distribution by the Issuer, or distribution of assets of the
Issuer of any kind or character, whether in cash, property or securities, to
which the Holders of the Securities or the Trustee would be entitled except for
the provisions of this Article Six A, shall be paid by the Issuer or by any
Custodian or other Person making such Payment or Distribution directly to the
holders of Senior Indebtedness or their representative or representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay all Senior Indebtedness in
full in cash, after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness, before any Payment or Distribution is
made to the Holders of the Securities or to the Trustee, except that the Trustee
will have a lien for the payment of its fees and expenses.

         In the event that, notwithstanding the foregoing, any Payment or
Distribution by the Issuer of any kind or character, whether in cash, property
or securities, prohibited by the foregoing, shall be received by the Trustee or
the Holders of the Securities before all Senior Indebtedness is paid in full in
cash, or provision is made for such payment to the satisfaction of the holders
thereof, and if such fact shall then have been or thereafter be made known to a
Trust Officer of the Trustee or, as the case may be, such Holder, then and in
such event such Payment or Distribution shall be paid over or delivered to the
holders of Senior Indebtedness or their


                                      -52-




   59



representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, for application
to the payment of all Senior Indebtedness remaining unpaid to the extent
necessary to pay all Senior Indebtedness in full in cash, after giving effect to
any concurrent Payment or Distribution to or for the holders of such Senior
Indebtedness, and, until so delivered, the same shall be held in trust by any
Holder of a Security as the property of the holders of Senior Indebtedness.

         The consolidation of the Issuer with, or the merger of the Issuer into,
another Person or the liquidation or dissolution of the Issuer following the
conveyance or transfer of its property as an entirety, or substantially as an
entirety, to another corporation upon the terms and conditions provided in
Article Eight shall not be deemed a dissolution, winding up, liquidation or
reorganization for the purposes of this Section 602A if such other Person shall,
as a part of such consolidation, merger, conveyance or transfer, comply with the
conditions stated in Article 5. Nothing in this Section shall apply to claims
of, or payments to, the Trustee under or pursuant to Section 606.

         The holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the obligations of the Holders of the Securities hereunder to the
holders of Senior Indebtedness: (i) change the manner, place or terms of payment
or change or extend the time of payment of, or renew or alter, Senior
Indebtedness, or otherwise amend in any manner Senior Indebtedness or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any
Person liable in any manner for the collection of Senior Indebtedness; and/or
(iv) exercise or refrain from exercising any rights against the Issuer and any
other Person.

         SECTION 603A. Subrogation of Securities. Subject to the payment in full
in cash of all amounts then due (whether by acceleration of the maturity thereof
or otherwise) on account of all Senior Indebtedness at the time outstanding, the
Holders of the Securities shall be subrogated to the rights of holders of Senior
Indebtedness to receive Payments or Distributions of cash, property or
securities of the Issuer applicable to the Senior Indebtedness until the
principal of and Interest on the Securities shall be paid in full; and, for the
purposes of such subrogation, no Payments or Distributions to the holders of
Senior Indebtedness to which the Holders of the Securities or the Trustee would
be entitled except for the provisions of this Article Six A, and no payments
over pursuant to the provisions of this Article Six A to the holders of Senior
Indebtedness by Holders of the Securities or the Trustee, shall, as between the
Issuer, its creditors other than holders of Senior Indebtedness, and the Holders
of the Securities, be deemed to be a payment by the Issuer to or on account of
the Senior Indebtedness. It is understood that the provisions of this Article
Six A are and are intended solely for the purpose of defining the relative
rights of the Holders of the Securities, on the one hand, and the holders of
Senior Indebtedness, on the other hand.

         Nothing contained in this Article Six A or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as among the Issuer, its
creditors other than the holders


                                      -53-




   60



of Senior Indebtedness, and the Holders of the Securities, the obligation of the
Issuer, which is absolute and unconditional, to pay to the Holders of the
Securities the principal of and Interest on the Securities as and when the same
shall become due and payable in accordance with their terms, or is intended to
or shall affect the relative rights of the Holders of the Securities and
creditors of the Issuer other than the holders of Senior Indebtedness, nor shall
anything herein or therein prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article Six A of
the holders of Senior Indebtedness in respect of cash, property or securities of
the Issuer received upon the exercise of any such remedy.

         Upon any payment or distribution of assets of the Issuer referred to in
this Article Six A, the Trustee, subject to the provisions of Sections 601 and
602, and the Holders of the Securities shall be entitled to rely upon any order
or decree made by any court of competent jurisdiction in which any dissolution,
winding up, liquidation or reorganization proceedings are pending, or
certificate of the Custodian or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of the Securities, for
the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of Senior Indebtedness and other indebtedness of the
Issuer, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article Six
A

         SECTION 604A. Authorization by Holders of Securities. Each Holder of a
Security by his acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate, as
between the Holder of the Security and the holders of Senior Indebtedness, the
subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes including, without limitation, to
execute, verify, deliver and file any proofs of claim which any holder of Senior
Indebtedness may at any time require in order to prove and realize upon any
rights or claims pertaining to the Securities and to effectuate the full benefit
of the subordination contained herein. Upon failure of the Trustee so to do, any
such holder of Senior Indebtedness shall be deemed to be irrevocably appointed
the agent and attorney-in-fact of the Holder to execute, verify, deliver and
file any such proofs of claim.

         SECTION 605A. Notices to Trustee. The Issuer shall give prompt written
notice to the Trustee of any fact known to the Issuer which would prohibit the
making of any payment of moneys to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article Six A Notwithstanding the
provisions of this Article or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts which would
prohibit the making of any payment of moneys to or by the Trustee in respect of
the Securities pursuant to the provisions of this Article Six A unless and until
a officer of the Trustee shall have received at its Corporate Trust Office
written notice thereof from the Issuer or a holder or holders of Senior
Indebtedness or from any trustee or agent therefor; and, prior to the receipt of
any such written notice, the Trustee, subject to the provisions of Sections 601
and 602, shall be entitled in all respects to assume that no such facts exist;
provided, however, that if a officer of the Trustee shall not have received at
least three Business Days prior to the date upon which by the terms hereof any
such moneys may become payable for any purpose (including, without limitation,
the payment of the principal of or Interest on any Security) with respect to
such moneys the notice provided for in this Section 605A, then, anything herein
contained to the


                                      -54-




   61



contrary notwithstanding, the Trustee shall have the full power and authority to
receive such moneys and to apply the same to the purpose for which they were
received and shall not be affected by any notice to the contrary which may be
received by it within three Business Days prior to such date.

         The Trustee shall be entitled to rely conclusively on the delivery to
it of a written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee on behalf of such holder) to establish that such
notice has been given by a holder of Senior Indebtedness or a trustee or agent
on behalf of any such holder. In the event that the Trustee determines in good
faith that further evidence is required with respect to the right of any Person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article Six A, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 10, and if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

         SECTION 606A. Trustee's Relation to Senior Indebtedness. The Trustee in
its individual capacity shall be entitled to all the rights set forth in this
Article Six A in respect of any Senior Indebtedness at any time held by it, to
the same extent as any other holder of Senior Indebtedness, and nothing in
Section 604 or elsewhere in this Indenture shall deprive the Trustee of any of
its rights as such holder.

         With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Six A, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not owe any fiduciary
duty to the holders of Senior Indebtedness and shall not be liable to any such
holder if it shall mistakenly pay over or distribute to Holders of the
Securities or the Issuer or any other Person money or assets to which any holder
of Senior Indebtedness shall be entitled by virtue of this Article Six A or
otherwise.

         SECTION 607 A. No Impairment of Subordination. No right of any present
or future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Issuer, the Trustee or the Holder of any of
the Securities or by any act, or failure to act, in good faith, by any such
holder of Senior Indebtedness, or by any noncompliance by the Issuer, the
Trustee or the Holder of any of the Securities with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof which any such
holder may have or otherwise be charged with.

         SECTION 608A. Article Six A Not To Prevent Events of Default. The
failure to make a payment on account of principal of or Interest on the
Securities by reason of any provision in this Article Six A shall not be
construed as preventing the occurrence of an Event of Default under Section 501.


                                      -55-




   62



         SECTION 609A. Paying Agents Other than the Trustee. In any case at any
time any Paying Agent other than the Trustee shall have been appointed by the
Issuer and be then acting hereunder, the term "Trustee" as used in this Article
Six A shall in such case (unless the context shall otherwise require) be
construed as extending to and including such Paying Agent within its meaning as
fully for all intents and purposes as if such Paying Agent were named in this
Article Six A in addition to or in place of the Trustee.

         SECTION 610A. Securities Senior to Subordinated Indebtedness. The
indebtedness represented by the Securities will be senior and prior in right of
payment to all Subordinated Indebtedness, to the extent and in the manner
provided in such Subordinated Indebtedness.

is furnished, provided, however, that, so long as the Trustee is the Security
Registrar, no such list shall be required to be furnished.

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

         SECTION 801. Consolidations and Mergers of Company and Sales, Leases
and Conveyances Permitted Subject to Certain Conditions. The Company may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other entity, provided that in any such
case, (1) either the Company shall be the continuing entity, or the successor
entity shall be an entity organized and existing under the laws of the United
States or a State thereof and such successor entity shall expressly assume the
due and punctual payment of the principal of (and premium or Make-Whole Amount,
if any) and any interest (including all Additional Amounts, if any, payable
pursuant to Section 1011) on all of the Securities, according to their tenor,
and the due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed by the Company by supplemental
indenture, complying with Article Nine hereof, satisfactory to the Trustee,
executed and delivered to the Trustee by such entity and (2) immediately after
giving effect to such transaction and treating any indebtedness which becomes an
obligation of the Company or any Subsidiary as a result thereof as having been

Event of Default, and no event which, after notice or the lapse of time, or
both, would become an Event of Default, shall have occurred and be continuing.

         SECTION 802. Rights and Duties of Successor Entity. In case of any such
consolidation, merger, sale, lease or conveyance and upon any such assumption by
the successor entity, such successor entity 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 entity, except in the event of a
lease, shall be relieved of any further obligation under this Indenture and the
Securities. Such successor entity 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
entity, 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 entity 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 of the same series 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.

         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 by any successor entity, complies
with the provisions of this Article and that all conditions precedent herein
provided for relating to such transaction have been complied with.

                                  ARTICLE NINE

                             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


                                      -58-




   65



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

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

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

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

         (6) to secure the Securities; or

         (7) to establish the form or terms of Securities of any series and any
related coupons as permitted by Sections 201 and 301; 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


                                      -59-




   66



         (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 or
Make-Whole Amount, 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 1011 (except as
contemplated by Section 801(1) and permitted by Section 901(1)), or reduce the
amount of the principal of an Original Issue Discount Security that would be due
and payable upon a declaration of acceleration of the Maturity thereof pursuant
to Section 502 or the amount thereof provable in bankruptcy pursuant to Section
504, or adversely affect any right of repayment at the option of the Holder of
any Security, or change any Place of Payment where, or the currency or
currencies, currency unit or units or composite currency or currencies in which,
any Security or any premium or the interest thereon is payable, or impair the
right to institute suit for the enforcement of any such payment on or after the
Stated Maturity thereof, (or, in the case of redemption or repayment at the
option of the Holder, on or after the Redemption Date or the Repayment Date, as
the case may be), or

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

         (3) modify any of the provisions of this Section, Section 513 or
Section 1012, 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.


                                      -60-




   67



         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.

         SECTION 907. Notice of Supplemental Indentures. Promptly after the
execution by the Company and the Trustee of any supplemental indenture pursuant

                                   ARTICLE TEN

                                    COVENANTS

         SECTION 1001. Payment of Principal, Premium (if any), Make-Whole Amount
(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 or Make-Whole Amount, if any) and
interest on and any Additional Amounts payable


                                      -61-




   68



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 1011 in respect of principal of
(or premium or Make-Whole Amount, if any, on) such a Security, shall be payable
only upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature. Unless otherwise
specified with respect to Securities of any series pursuant to Section 301, at
the option of the Company, all payments of principal may be paid by check to the
registered Holder of the Registered Security or other person entitled thereto
against surrender of such Security.

         SECTION 1002. Maintenance of Office or Agency. If Securities of a
series are issuable only as Registered Securities, the Company shall maintain in
each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment or
conversion, where Securities of that series may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company will
maintain: (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment or conversion, where any Registered Securities of that
series may be surrendered for registration of transfer, where Securities of that
series may be surrendered for exchange, where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served and where Bearer Securities of that series and related coupons may be
presented or surrendered for payment or conversion in the circumstances
described in the following paragraph (and not otherwise); (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment
(including payment of any Additional Amounts payable on Securities of that
series pursuant to Section 1011) 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 1011) or conversion at the offices specified in the Security, in London,
England, and the Company hereby


                                      -62-




   69



appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands, and the Company hereby appoint 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 1011) shall be made at the office of the Company's Paying
Agent in the Borough of Manhattan, The City of New York, if (but only if)
payment in Dollars of the full amount of such principal, premium or Make-Whole
Amount, interest or Additional Amounts, as the case may be, at all offices or
agencies outside the United States maintained for the 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 designations; 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 Borough of Manhattan, The
City of New York, 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 301, 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 the 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, on or before each due date
of the principal of (and premium or Make-Whole Amount, 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 or Make-Whole Amount, if any) or
interest or Additional Amounts so becoming due


                                      -63-




   70



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 or Make-Whole Amount, 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 or Make-Whole Amount, 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 or Make-Whole Amount, 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 or Make-Whole Amount, 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 terms 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 or Make-Whole Amount, 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 or Make-Whole Amount, 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 or Make-Whole Amount, if
any) or interest on, or any Additional


                                      -64-




   71



Amounts in respect of, any 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. Intentionally Omitted.

         SECTION 1005. Existence. Subject to Article Eight, the Company will do
or cause to be done all things necessary to preserve and keep in full force and
effect its existence, rights (by partnership agreement and statute) 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 and that the loss thereof
is not disadvantageous in any material respect to the Holders.

         SECTION 1006. Maintenance of Properties. The Company will cause all of
its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that the Company and its Subsidiaries
shall not be prevented from selling or otherwise disposing of for value their
respective properties in the ordinary course of its business.

         SECTION 1007. Insurance. The Company will, and will cause each of its
Subsidiaries to, keep all of its insurable properties insured against loss or
damage at least equal to their then full insurable value with insurers of
recognized responsibility and having an A.M. Best policy holder's rating of not
less than A-V.

         SECTION 1008. Payment of Taxes and Other Claims. The Company will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary; provided, however, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings or for which the Company has
set apart and maintains an adequate reserve.

         SECTION 1009. 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


                                      -65-




   72



pursuant to such Sections 13 or 15(d) if the Company were so subject (the
"Financial Information"), 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 also will in any event (x) within 15 days of each Required
Filing Date: (i) transmit by mail to all Holders of Securities, as their names
and addresses appear in the Security Register, without cost to such Holders,
copies of the Financial Information; and (ii) file with the Trustee copies of
the Financial Information, and (y) 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.

         SECTION 1010. Statement as to Compliance. The Company will, in
accordance with Section 314 of the TIA, 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 1010, such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture.

         SECTION 1011. 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
10 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


                                      -66-




   73



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. If the Trustee or any Paying Agent, as the case may be,
shall not so receive the above-mentioned certificate, then the Trustee or such
Paying Agent shall be entitled (i) to assume that no such withholding or
deduction is required with respect to any payment of principal or interest with
respect to any Securities of a series or related coupons until it shall have
received a certificate advising otherwise and (ii) to make all payments of
principal and interest with respect to the Securities of a series or related
coupons without withholding or deductions until otherwise advised. The Company
covenants to indemnify the Trustee and any Paying Agent for, and to hold them
harmless against, any loss, liability or expense reasonably incurred without
negligence or bad faith on their part arising out of or in connection with
actions taken or omitted by any of them or in reliance on any Officers'
Certificate furnished pursuant to this Section or in reliance on the Company's
not furnishing such an Officers' Certificate.

         SECTION 1012. Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1005 to 1009, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         SECTION 1101. Applicability of Article; Redemption to Maintain REIT
Status.

         (a) 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.

         (b) The Company shall redeem all or a portion of the Securities of any
series as necessary to comply with any requirement for the Trust's continued
qualification as a real estate investment trust under the Internal Revenue Code
of 1986, as amended.

         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
all or 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


                                      -67-




   74



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, 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 the Holder receives the notice.

         All notices of redemption shall state:

         (1) the Redemption Date,

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

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

         (4) in case any Security is to be redeemed in part only, the notice
which relates to such Security shall state that on and after the Redemption
Date, upon surrender of such


                                      -68-




   75



Security, the holder will receive, without a 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 unless the Company shall default in the payment of the
Redemption Price and any accrued interest thereon,

         (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 date fixed for redemption 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 and the Trustee for
such series and any Paying Agent is furnished,

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

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

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

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

         SECTION 1105. Deposit of Redemption Price. At least one Business Day
prior to 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, 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.


                                      -69-




   76



         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, 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 Regular
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 by the Company shall not be so
paid upon surrender thereof for redemption by reason of a failure to comply with
Section 1105, the principal (and premium or Make-Whole Amount, 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) 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


                                      -70-




   77



without service charge a new Security or Securities of the same series, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

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

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

         SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.
The Company may, in satisfaction of all or any part of any mandatory sinking
fund payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed whether 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 the series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of such 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


                                      -71-



   78



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 an at the expense of the Company in the manner provided
in Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

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

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

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


                                      -72-




   79



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 that provide 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 portion 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 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, on the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable 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 with 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 Regular 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 it such security or indemnity
as they may require to save it 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


                                      -73-




   80



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 by reason of a failure by the Company to
comply with this Section 1304, such principal amount (together with interest, if
any, thereon accrued to such Repayment Date) shall, until paid, bear interest
from the Repayment Date at the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) set forth in such Security.

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

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

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


                                      -74-




   81



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
or Make-Whole Amount, 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 1011, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article. Subject to
compliance with this Article Fourteen, the Company may exercise its option under
this Section notwithstanding the prior exercise of its option under Section 1403
with respect to such Securities and any coupons appertaining thereto.

         SECTION 1403. Covenant Defeasance. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be released from its obligations under
Sections 1004 to 1009, inclusive and, if specified pursuant to Section 301, its
obligations under any other covenant, with respect to such Outstanding
Securities and 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 to 1009, inclusive, 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 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(8) 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

Fourteen applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with their terms will provide, not later than one day before the due
date of any payment of principal of (and premium or Make-Whole Amount, if any)

                                      -75-




   82



coupons appertaining thereto, money in an amount, or (3) a combination thereof,
in any case, in an amount, sufficient, without consideration of any reinvestment
of such principal and interest, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered the Trustee, to pay and discharge, and which shall be applied by the
Trustee (or other qualifying trustee) to pay and discharge, the principal of
(and premium or Make-Whole Amount, if any) and interest, if any, on such
Outstanding Securities and any coupons appertaining thereto on the Stated
Maturity of such principal or installment of principal or interest or analogous
payments applicable to such Outstanding Securities and any coupons appertaining
thereto on the day on which such payments are due and payable in accordance with
the terms of this Indenture and of such Securities and any coupons appertaining
thereto.

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

                (c) No Event of Default or event which with notice or lapse of
time or both would become an Event of Default with respect to such Securities
and any coupons appertaining thereto shall have occurred and be continuing on
the date of such deposit or, insofar as Sections 501(6) and 501(7) are
concerned, at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period).

                (d) In the case of an election under Section 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

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

                (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company with
respect to the trust funds


                                      -76-




   83



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 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 or Make-Whole Amount, 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 or Make-Whole
Amount, 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, except, with
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the 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, subject to
Section 606, 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


                                      -77-




   84



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.

of any series for any purpose specified in Section 1501, to be held at such time
and at such place in the Borough of Manhattan, The City of New York, or in
London as the Trustee shall determine. Notice of every meeting of Holders of

         SECTION 1504. Quorum; Action. The Persons entitled to vote a majority
in principal amount of the Outstanding Securities of a series shall constitute a
quorum for a meeting of Holders of Securities of such series; provided, however,
that if any action is to be taken at such meeting with respect to a consent or

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

presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of a

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 specific percentage, which is
less than a majority, in principal amount of the Outstanding Securities of a
series may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders
of such specified percentage in principal amount of the Outstanding Securities
of that series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

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 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


                                      -80-




   87



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

         SECTION 1507. Evidence of Action Taken by Holders. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by a specified percentage in principal
amount of the Holders of any or all series may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such specified
percentage of Holders in person or by agent duly appointed in writing; and,
except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee.
Proof and execution of any instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Article
Six) conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Article.

         SECTION 1508. Proof of Execution of Instruments. Subject to Article
Six, the execution of any instrument by a Holder or his agent or proxy may be
proved in accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee.

         This is to certify that, as of the date hereof, and except as set forth
below, the above-captioned Securities held by you for our account (i) are owned
by person(s) that are not citizens or residents of the United States, domestic
companies, domestic corporations or any estate or trust the income of which is
subject to United States federal income taxation regardless of its source
("United States person(s)"), (ii) are owned by United States person(s) that are
(a) foreign branches of United States financial institutions (financial

for their own account or for resale, or (b) United States person(s) who acquired
the Securities through foreign branches of United States financial institutions
and who hold the Securities through such United States financial institutions on
the date hereof (and in either case (a) or (b), each such United States
financial institution hereby agrees, on its own behalf or through its agent,
that you may advise Liberty Property Limited Partnership or its agent that such
financial institution will comply with the requirements of Section 165(j)(3)(A),
(B) or (C) of the United States Internal Revenue Code of 1986, as amended, and
the regulations thereunder), or (iii) are owned by United States or foreign

has not acquired the Securities for purposes of resale directly or indirectly to
a United States person or to a person within the United States or its

         Liberty Property Limited Partnership, a Pennsylvania limited
partnership (the "Issuer," which term includes any successor under the Indenture
hereinafter referred to), for value received, hereby promises to pay to Cede &
Co. or registered assigns, upon presentation, the principal sum of
_______________ Dollars ($________________) on __________________, ________, and
to pay interest thereon from _________________, _________ (or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for), semi-annually in arrears on ____________________ and _________________ of
each year, commencing on ________________, 199__, and at Maturity, at a rate of
interest of ___________ % per annum, until payment of said principal sum has
been made or duly provided for. Any capitalized term not defined herein shall
have the meaning assigned to it in that certain Indenture by and among the
Issuer and The First National Bank of Chicago, a _____________________________,
dated as of ___________________, 199__.




   97



         The interest so payable and punctually paid or duly provided for on an
Interest Payment Date and at Maturity will be paid to the Holder in whose name
this Note (or one or more predecessor Notes) is registered at the close of
business on the Regular Record Date for such payment, which will be 15 calendar
days (regardless of whether such day is a Business Day) next preceding such
Interest Payment Date or Maturity, as the case may be. Any interest not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holder on such Regular Record Date, and may either be paid to the Holder in
whose name this Note (or one or more predecessor Notes) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Notes of this series not less than ten (10) days prior to such Special Record
Date, or may be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange or which the Notes of this
series may be listed, and upon such notice as may be required by such exchange,
as more fully provided in the Indenture.

         The principal and Make-Whole Amount, if any, of this Note payable at
Maturity will be paid against presentation and surrender of this Note at the
office or agency of the Issuer maintained for that purpose in The Borough of
Manhattan, The City of New York. The Issuer hereby initially designates the
Corporate Trust Office of the Trustee in The City of New York as the office to
be maintained by it where Notes may be presented for payment, registration of
transfer or exchange and where notices or demands to or upon the Issuer in
respect of the Notes or the Indenture may be served.

         Interest payable on this Note will be computed on the basis of a
360-day year consisting of twelve 30-day months. If any Interest Payment Date or
Maturity would otherwise be a day that is not a Business Day, the required
payment will be made on the next succeeding Business Day with the same force and
effect as if it were paid on the date such payment was due, and no interest will
accrue on the amount so payable for the period from and after such Interest
Payment Date or Maturity, as the case may be.

         [Notes of this series may be redeemed at any time at the option of the
Issuer, in whole or in part, upon notice to the Holders of not more than 60 nor
less than 30 days prior to the Redemption Date, at a redemption price equal to
the sum of (i) the principal amount of the Notes being redeemed plus accrued
interest thereon to the Redemption Date and (ii) the Make-Whole Amount, if any,
with respect to such Notes.]

         Payments of principal, Make-Whole Amounts, if any, and interest in
respect of this Note will be made by wire transfer of immediately available
funds, in such coin or currency as at the time of payment is legal tender for
the payment of public and private debts, so long as this Note is in global form
as described in Section 203 of the Indenture. If this Note is not in global
form, all such payments will be made by wire transfer of immediately available
funds if the Holder hereof at the applicable record date shall have provided
wire transfer instructions to the Trustee, received by the Trustee no later than
fifteen (15) days prior to the applicable payment date, and otherwise payment
shall be made in accordance with Section 307 of the Indenture. Such wire
transfer instructions shall remain in effect until revoked in a writing received
by the Trustee from the Holder hereof.

         REFERENCE IS MADE TO THE FURTHER PROVISIONS OF THIS NOTE SET FORTH ON
THE REVERSE HEREOF. SUCH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME
EFFECT AS THOUGH FULLY SET FORTH AT THIS PLACE.

         This Note shall not be entitled to the benefits of the Indenture
referred to on the reverse hereof or be valid or become obligatory for any
purpose until the certificate of authentication hereon shall have been signed by
the Trustee under such Indenture.

         IN WITNESS WHEREOF, the Issuer has caused this instrument to be signed
manually or by facsimile by its duly authorized officers.

                    ___% ________________ Notes due ________

         This security is one of a duly authorized issue of debentures, notes,
bonds or other evidences of indebtedness of the Issuer (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under an Indenture dated as of ______________________ , 1997 (the "Indenture"),
between the Issuer and The First National Bank of Chicago, as Trustee (herein
called the "Trustee," which term includes any successor trustee under the
Indenture with respect to the series of Securities of which this Note is a
part), to which Indenture and all indentures supplemental thereto reference is
hereby made for a description of the respective rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Issuer and the
Holders of the Securities, and of the terms upon which the Securities are, and
are to be, authenticated and delivered. The Securities may be issued in one or
more series, which different series may be issued in various aggregate principal
amounts, may mature at different times, may bear interest (if any) at different
rates, may be subject to different redemption provisions (if any), and may
otherwise vary provided in the Indenture. This Security is one of a series
designated on the first page hereof, limited in aggregate principal amount to $
____________________ .

         In case an Event of Default with respect to Securities of this series
shall have occurred and be continuing, the principal of, and premium or
Make-Whole Amount, if any, may be declared, and upon such declaration shall
become, due and payable, in the manner, with the effect, and subject to the
conditions provided in the Indenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless (i) such Holder shall have previously
given written notice to the Trustee of a continuing Event of Default with
respect to the Outstanding Securities of this series, (ii) the Holders of not
less than 25% in principal amount of the Outstanding Securities of this 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, (iii) such Holder
or Holders have offered reasonable indemnity to the Trustee against the costs,
expenses and liabilities to be incurred in compliance with such request, (iv)
the Trustee shall have failed to institute any such proceeding for 60 days after
its receipt of such notice, request and offer of indemnity and (v) the Trustee
shall not have received from the Holders of a majority in principal amount of
Outstanding Securities of this series a direction inconsistent with such
request.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Issuer and the Trustee with the
consent of the Holders of not less than a majority in principal amount of the
Securities of each series at the time Outstanding affected thereby. The
Indenture also contains provisions permitting the Holders of at least a majority
in principal amount of the Securities of such series Outstanding, on behalf of
the Holders of all Securities of such series, to



   100



waive compliance by the Issuer with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holders of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of, premium or Make-Whole
Amount, if any, and interest on this Security at the times, place and rate, and
in the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Issuer in any Place of Payment where the principal of,
premium or Make-Whole Amount, if any, on, and interest on this Security are
payable, duly endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Issuer and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

         The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series of a different authorized denomination, as
requested by the Holder surrendering the same.

         No service charge shall be made for any registration of transfer or
exchange of Securities of this series, but the Issuer may require payment of a

the Issuer or any successor, under any rule of law, statute or constitutional
provisions or by the enforcement of any assessment or by any legal or equitable
proceeding or otherwise, all such liability being expressly waived and released
by the acceptance of this Security by the Holder thereof and as part of the
consideration for the issue of the Securities of this series. The Holder of this
Security acknowledges by acceptance of this Security that its sole remedies
under the Indenture for any Default by the Issuer in the payment of the
principal of, or any premium or Make-Whole Amount, if any, interest or any
amounts due, or claimed to be due, on this Security, or otherwise, are limited

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Issuer has caused "CUSIP" numbers to be

Securities. No representation is made as to the correctness or accuracy of such
CUSIP numbers as printed on the Securities, and reliance may be placed only on
the other identification numbers printed hereon.

         Terms used herein that are defined in the Indenture shall have the
respective meanings assigned them in the Indenture.
