SECTION 1.04. Acts of Holders. (i) Any request, demand, authorization,

such Holders in person or by an agent duly appointed in writing. If Securities
of a series are issuable in whole or in part 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 may, alternatively,
be embodied in and evidenced by the record of Holders of Securities voting in
favor thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities duly called and held in accordance with the
provisions of Article Sixteen 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 and so voting at any such
meeting. Proof of execution of any such instrument or of a writing appointing
any such agent, or the holding by any Person of a Security, shall be sufficient
for any purpose of this Indenture and (subject to Section 8.01) conclusive in
favor of the Trustee and the Company, if made in the manner provided in this
Section. The record of any meeting of Holders of Securities shall be proved in
the manner provided in Section 16.06.

(ii) 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 the
certificate of any 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
or on behalf of any legal entity other than an individual, such certificate or
affidavit shall also constitute proof of the authority of the Person executing
the same. 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 manner which the Trustee deems sufficient.

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

(iv) The principal amount and serial numbers of Bearer Securities held by any
Person, and the date of holding the same, may be proved by the production of
such Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank 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.

                                       18
<PAGE>

(v) The fact and date of execution of any such instrument or writing, the
authority of the Person executing the same and the principal amount and serial
numbers of Bearer Securities held by the Person so executing such instrument or
writing and the date of holding the same may also be proved in any other manner
which the Trustee deems sufficient; and the Trustee may in any instance require
further proof with respect to any of the matters referred to in this Section.

(vi) Any request, demand, authorization, direction, notice, consent, waiver or
other action by 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 any
action taken, suffered or omitted by the Trustee or the Company in reliance
thereon, whether or not notation of such action is made upon such Security.

(vii) For purposes of determining the principal amount of Outstanding Securities
of any series the Holders of which are required, requested or permitted to give
any request, demand, authorization, direction, notice, consent, waiver or take
any other Act under the Indenture, each Security denominated in a Foreign
Currency or composite currency shall be deemed to have the principal amount
determined by the Exchange Rate Agent by converting the principal amount of such
Security in the currency in which such Security is denominated into Dollars at
the Exchange Rate as of the date such Act is delivered to the Trustee and, where
it is hereby expressly required, to the Company, by Holders of the required
aggregate principal amount of the Outstanding Securities of such series (or, if
there is no such rate on such date, such rate on the date determined as
specified as contemplated in Section 3.01).

(viii) The Company may, in the circumstances permitted by the Trust Indenture
Act, set a record date for purposes of determining the identity of Holders of
Securities of any series entitled to give any request, demand, authorization,
direction, notice, consent, waiver or take any other Act, or to vote or consent
to any action by vote or consent authorized or permitted to be given or taken by
Holders of Securities of such series. If not set by the Company prior to the
first solicitation of a Holder of Securities of such Series made by any Person
in respect of any such action, or in the case of any such vote, prior to such
vote, such record date shall be the later of 30 days prior to the first
solicitation of such consent or the date of the most recent list of Holders of
such Securities furnished to the Trustee pursuant to Section 6.01 prior to such
solicitation.

(ix) Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount. Any notice given or action
taken by a Holder or its agents with regard to different parts of such principal
amount pursuant to this paragraph shall have the same effect as if given or
taken by separate Holders of each such different part. (x) Without limiting the
generality of the foregoing, unless otherwise specified pursuant to Section 3.01
or pursuant to one or more indentures supplemental hereto, a Holder, including a
Depositary that is the Holder of a Global Security, may make, give or take, by a
proxy or proxies duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other action provided in this Indenture to
be made, given or taken by Holders, and a Depositary that is the Holder of a
Global Security may provide its proxy or proxies to the beneficial owners of
interests in any such Global Security through such Depositary's standing
instructions and customary practices.

(xi) The Company may fix a record date for the purpose of determining the
Persons who are beneficial owners of interests in any Global Security held by a
Depositary entitled under the procedures of such Depositary to make, give or
take, by a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be made, given or taken by Holders. If such a record date is
fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request,
demand, authorization, direction, notice, consent, waiver or other action,
whether or not such Holders remain Holders after such record date. No such
request, demand, authorization, direction, notice, consent, waiver or other
action shall be valid or effective if made, given or taken more than 90 days
after such record date.

SECTION 1.05. Notices, etc., to Trustee and Company. Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

(i) 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 Principal Corporate Trust Office, or

(ii) the Company by any Holder or by the Trustee shall be sufficient for every
purpose hereunder (unless otherwise herein expressly provided) if in writing and
mailed, first-class, postage prepaid, to the Company, to the attention of its
Treasurer, 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 1.06. Notices to Holders; Waiver. Where this Indenture or any Security
provides for notice to Holders of any event,

(1) such notice shall be sufficiently given (unless otherwise herein or in such
Security expressly provided) if in writing and mailed, first- class, postage
prepaid, to each Holder of Registered Securities affected by such event, at his
address as it appears in the Security

                                       19
<PAGE>

Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice.

(2) such notice shall be sufficiently given to Holders of Bearer Securities if
published in an Authorized Newspaper in The City of New York and, if the
Securities of such series are then listed on The International Stock Exchange of
the United Kingdom and the Republic of Ireland Limited and such stock exchange
shall so require, in London and, if the Securities of such series are then
listed on the Luxembourg Stock Exchange and such stock exchange shall so
require, in Luxembourg and, if the Securities of such series are then listed on
any other stock exchange and such stock exchange shall so require, in any other
required city outside the United States, or, if not practicable, elsewhere in
Europe on a Business Day at least twice, the first such publication to be not
earlier than the earliest date, and not later than the latest date, prescribed
for the giving of such notice.

In case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice to Holders of
Registered Securities by mail, then such notification as shall be made with the
approval of the Trustee shall constitute a sufficient notification for every
purpose hereunder. In any case where notice to Holders of Registered Securities
is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder of Registered Securities shall affect
the sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice by publication to Holders of Bearer
Securities given as provided above. In case 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 Holders of Bearer Securities as
provided above, nor any defect in any notice so published, shall affect the
sufficiency of any notice mailed to Holders of Registered Securities as provided
above.

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 1.07. Language of Notices, Etc. 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.

SECTION 1.08. Conflict with Trust Indenture Act. If and to the extent that any
provision of this Indenture limits, qualifies or conflicts with the duties
imposed by, or with another provision (an "incorporated provision") included in
this Indenture by operation of Sections 310 and 318, inclusive, of the TIA, such
imposed duties or incorporated provision shall control.

SECTION 1.09. 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 1.10. Successors and Assigns. All covenants and agreements in this
Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

SECTION 1.11. Separability Clause. In case any provision in this Indenture or in
the Securities 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 1.12. Benefits of Indenture. Nothing in this Indenture or in the
Securities, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, the Holders and, to the extent provided
in Article Fourteen hereof, the holders of Senior Indebtedness and creditors in
respect of General Obligations, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

SECTION 1.13. Legal Holidays. In any case where any Interest Payment Date,
Stated Maturity, Repayment Date or Redemption Date of any Security or any date
on which any Defaulted Interest is proposed to be paid shall not be a Business
Day at any Place of Payment, then (notwithstanding any other provisions of the
Securities or this Indenture) payment of the principal of, premium, if any, or
interest on any Securities need not be made at such Place of Payment on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date, Stated Maturity, Repayment
or Redemption Date or on the date on which Defaulted Interest is proposed to be
paid and, if such payment is made, no interest shall accrue on such payment for
the period from and after any such Interest Payment Date, Stated Maturity,
Repayment Date or Redemption Date or date on which Defaulted Interest is
proposed to be paid, as the case may be.

determined in the manner provided in such Officers' Certificate or in any such
indenture supplement hereto.

Securities of any particular series may be issued at various times, with
different dates on which the principal or any installment of principal is
payable, with different rates of interest, if any, or different methods by which
rates of interest may be determined, with different dates on which such interest
may be payable and with different Redemption Dates or Repayment Dates and may be
denominated in different currencies or payable in different currencies.

All Securities shall be subordinate and junior in right of payment to the
obligations of the Company to holders of Senior Indebtedness and creditors in
respect of General Obligations of the Company as provided in Article Fourteen.

SECTION 3.02. Denominations. The Securities of each series shall be issuable in
such form and denominations as shall be specified as contemplated by Section
3.01. In the absence of any specification with respect to the Securities of any
series, the Registered Securities of each series shall be issuable only as
Securities without coupons in denominations of $1,000 and any integral multiple
thereof and the Bearer Securities of each series, if any, shall be issuable with
coupons and in denominations of $5,000 and any integral multiple thereof.

SECTION 3.03. Execution, Authentication, Delivery and Dating. The Securities
shall be executed on behalf of the Company by its Chairman of the Board, its
President, a Vice Chairman of the Board, or one of its Vice Presidents and by
its Secretary or one of its Assistant Secretaries. The signatures of any or all
of these officers on the Securities may be manual or facsimile. Coupons shall
bear the facsimile signature of the Company's Chairman of the Board, its
President, a Vice Chairman of the Board or one of its Vice Presidents.

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

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
coupons 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 shall, upon receipt of the Company
Order, authenticate and deliver such Securities as in this Indenture provided
and not otherwise; 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 a Bearer Security may
be delivered in connection with its original issuance only if the Person
entitled to receive such Bearer Security shall have delivered to the Trustee, or
such other Person as shall be specified in a temporary Global Security delivered
pursuant to Section 3.04, a certificate in the form required by Section 3.11(i).

If the Company shall establish pursuant to Section 3.01 that the Securities of a
series are to be issued in whole or in part in the form of one or more Global
Securities in registered or permanent bearer form, then the Company shall
execute and the Trustee shall, in accordance with this Section and a Company
Order for the authentication and delivery of such Global Securities with respect
to such series, authenticate and deliver one or more Global Securities in
permanent or temporary form that (i) shall represent and shall be denominated in
an aggregate amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by one or more Global Securities,

                                       23
<PAGE>

(ii) shall be registered, if in registered form, in the name of the Depositary
for such Global Security or Securities or the nominee of such Depositary and
(iii) shall be delivered by the Trustee to such Depositary or pursuant to such
Depositary's instructions.

Each Depositary designated pursuant to Section 3.01 for a Global Security in
registered form must, at the time of its designation and at all times while it
serves as Depositary, be a clearing agency registered under the Exchange Act,
and any other applicable statute or regulation.

In authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 8.01) shall be fully protected in
relying upon, an Opinion of Counsel complying with Section 1.02 and stating
that,

(i) the form of such Securities and coupons, if any, has been established in
conformity with the provisions of this Indenture;

(ii) the terms of such Securities and coupons, if any, or the manner of
determining such terms have been established in conformity with the provisions
of this Indenture;

(iii) that such Securities and coupons, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company, enforceable against the Company in accordance with
their terms, subject to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and other laws of general applicability relating to
or affecting the enforcement of creditors' rights and to general principles of
equity; and

(iv) such other matters as the Trustee may reasonably request.

The Trustee shall not be required to authenticate such Securities if the issue
thereof will adversely affect the Trustee's own rights, duties 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
3.01 and of this Section 3.03, if all Securities of a series are not to be
originally issued at one time, it shall not be necessary to deliver the Board
Resolution or Officers' Certificate otherwise required pursuant to Section 3.01
or the Company Order and Opinion of Counsel otherwise required pursuant to this
Section 3.03 at or prior to the time of authentication of each Security of such
series if such documents are delivered at or prior to the authentication upon
original issuance of the first Security of such series to be issued and such
documents reasonably contemplate the issuance of all Securities of such series;
provided that any subsequent request by the Company to the Trustee to
authenticate Securities of such series upon original issuance shall constitute a
representation and warranty by the Company that as of the date of such request,
the statements made in the Officers' Certificate or other certificates delivered
pursuant to Sections 1.02 and 3.01 shall be true and correct as if made on such
date.

A Company Order, Officers' Certificate or Board Resolution or supplemental
indenture delivered by the Company to the Trustee in the circumstances set forth
in the preceding paragraph may provide that Securities which are the subject
thereof will be authenticated and delivered by the Trustee or its agent on
original issue from time to time in the aggregate principal amount, if any,
established for such series pursuant to such procedures acceptable to the
Trustee as may be specified from time to time by Company Order upon the
telephonic, electronic or written order of Persons designated in such Company
Order, Officers' Certificate, supplemental indenture or Board Resolution and
that such Persons are authorized to determine, consistent with such Company
Order, Officers' Certificate, supplemental indenture or Board Resolution, such
terms and conditions of said Securities as are specified in such Company Order,
Officers' Certificate, supplemental indenture or Board Resolution.

Each Registered Security shall be dated the date of its authentication; and
unless otherwise specified as contemplated by Section 3.01, each Bearer Security
and any temporary Global Security referred to in Section 3.04 shall be dated as
of the date of original issuance of such Security.

No Security or coupon appertaining thereto shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose, unless there
appears on such Security a certificate of authentication substantially in the
form provided for herein executed by the Trustee by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder. Except as permitted by Section 3.06, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant coupons for
interest then matured have been detached and canceled. Notwithstanding the
foregoing, if any Security or portion thereof shall have been duly authenticated
and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Security to the Trustee for cancelation as provided
in Section 3.09 together with a written statement (which need not comply with
Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that
such Security or portion thereof 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 3.04. Temporary Securities. (a) Pending the preparation of definitive
Securities of any series, the Company may execute, and upon Company Order and
the receipt of the certifications and opinions required under Sections 3.01 and
3.03, the Trustee shall

                                       24
<PAGE>

authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized
denominations, 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 evidenced by their execution of such
Securities. In the case of any series which may be issuable as Bearer
Securities, such temporary Securities may be in global form, representing such
of the Outstanding Securities of such series as shall be specified therein.

(b) Unless otherwise provided pursuant to Section 3.01:

(i) Except in the case of temporary Securities in global form, each of which
shall be exchanged in accordance with the provisions of the following
paragraphs, if temporary Securities of any series are issued, the Company will
cause definitive Securities of such series to be prepared without unreasonable
delay. After the preparation of definitive Securities, 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 cancelation of any one or more temporary
Securities of any series (accompanied, if applicable, by all unmatured coupons
and all matured coupons in default appertaining thereto), the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of such 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
3.03. 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.

(ii) If temporary Securities of any series are issued in global form, any such
temporary Global Security shall, unless otherwise provided in such temporary
Global Security, be delivered to the London office of a depositary or common
depositary (the "Common Depositary"), for the benefit of the operator of
Euroclear and CEDEL S.A., for credit to the respective accounts of the
beneficial owners of such Securities (or to such other accounts as they may
direct). Upon receipt of written instructions (which need not comply with
Section 1.02) signed on behalf of the Company by any Person authorized to give
such instructions, the Trustee or any Authenticating Agent shall endorse such
temporary Global Security to reflect the initial principal amount, or an
increase in the principal amount, of Outstanding Securities represented thereby.
Until such initial endorsement, such temporary Global Security shall not
evidence any obligation of the Company. Such temporary Global Security shall at
any time represent the aggregate principal amount of Outstanding Securities
theretofore endorsed thereon as provided above, subject to reduction to reflect
exchanges as described below.

(iii) Unless otherwise specified in such temporary Global Security, and subject
to the second proviso in the following paragraph, the interest of a beneficial
owner of Securities of a series in a temporary Global Security shall be
exchanged for definitive Securities including a definitive Global Bearer
Security) of such series and of like tenor following the Global Exchange Date
(as defined below) when the account holder instructs Euroclear or CEDEL S.A., as
the case may be, to request such exchange on his behalf and delivers to
Euroclear or CEDEL S.A., as the case may be, a certificate in the form required
by Section 3.11(i), dated no earlier than 15 days prior to the Global Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and CEDEL S.A., 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 in the event that such Person does not take delivery
of such definitive Securities in person at the offices of Euroclear or CEDEL
S.A. 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.

(iv) 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 as the "Global Exchange Date" (the "Global Exchange Date"), the Company
shall deliver to the Trustee, or, if the Trustee appoints an Authenticating
Agent pursuant to Section 8.14, to any such Authenticating Agent, definitive
Securities in aggregate principal amount equal to the principal amount of such
temporary Global Security, executed by the Company. Unless otherwise specified
as contemplated by Section 3.01, such definitive Securities shall be in the form
of Bearer Securities or Registered Securities, or any combination thereof, as
may be specified by the Company, the Trustee or any such Authenticating Agent,
as may be appropriate. On or after the Global Exchange Date, such temporary
Global Security shall be surrendered by the Common Depositary to the Trustee or
any such Authenticating Agent, 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 or any such Authenticating Agent 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, which, except as otherwise
specified as contemplated by Section 3.01, shall be in the form of Bearer
Securities or Registered Securities, or any combination 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 Global 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 Global Exchange
Date or a subsequent date and signed by CEDEL S.A., as to the portion of such

                                       25
<PAGE>

temporary Global Security held for its account then to be exchanged, each in the
form required by Section 3.11(ii); and provided further that a definitive Bearer
Security (including a definitive global Bearer Security) shall be delivered in
exchange for a portion of a temporary Global Security only in compliance with
the conditions set forth in Section 3.03.

(v) Upon any exchange of a portion of any such temporary Global Security, such
temporary Global Security shall be endorsed by the Trustee or any such
Authenticating Agent, as the case may be, to reflect the reduction of the
principal amount evidenced thereby, whereupon its remaining principal amount
shall be reduced for all purposes by the amount so exchanged. Until so exchanged
in full, such temporary Global Security shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities of such series
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 3.01, interest payable on such temporary Global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Global Exchange Date shall be payable, without interest,
to Euroclear and CEDEL S.A. on or after such Interest Payment Date upon delivery
by Euroclear and CEDEL S.A. to the Trustee or the Paying Agent, as the case may
be, of a certificate or certificates in the form required by Section 3.11(iii),
for credit on or after such Interest Payment Date to the respective accounts of
the 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
S.A., as the case may be, a certificate in the form required by Section
3.11(iv). Any interest so received by Euroclear and CEDEL S.A. and not paid as
herein provided prior to the Global Exchange Date shall be returned to the
Trustee or Paying Agent, as the case may be, which, upon expiration of two years
after such Interest Payment Date, shall repay such interest on Company Request
in accordance with Section 5.03.

SECTION 3.05. Registration, Registration of Transfer and Exchange. With respect
to Registered Securities, the Company shall keep or cause to be kept a register
(sometimes referred to 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 the registration of transfers of
Registered Securities and the Company shall appoint a "Security Registrar", and
may appoint any "Co-Security Registrar", as may be appropriate, to keep the
Security Register. Such Security Register shall be in written form or in any
other form capable of being converted into written form within a reasonable
time. At all reasonable times the information contained in such Security
Register shall be available for inspection by the Trustee at the office of the
Security Registrar. In the event that any Registered Securities issued hereunder
have the City of New York as a Place of Payment, the Company shall appoint
either a Security Registrar or Co-Security Registrar located in the City of New
York.

Upon surrender for registration of transfer of any Registered Security of any
series at the office or agency of the Company maintained pursuant to Section
5.02 for such purpose in a Place of Payment for such 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
such series of any authorized denominations and of a like aggregate principal
amount, tenor and Stated Maturity.

At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of such series, of any authorized
denominations and of like aggregate principal amount, tenor and Stated Maturity,
upon surrender of the Securities to be exchanged at such office or agency.
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.

Registered Securities may not be exchanged for Bearer Securities.

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, such 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 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 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 any such payment from the Company;
provided, however, that interest represented by coupons shall be payable only
upon presentation and surrender of those coupons at an office or agency of a
Paying Agent, maintained pursuant to Section 5.02 for such purpose, 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 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 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.

Notwithstanding any other provision of this Section, unless and until it is
exchanged in whole or in part for individual Securities represented thereby, a
Global Security representing all or a portion of the Securities of a series may
not be transferred except as a whole by the Depositary for such series to a
nominee of such Depositary or by a nominee of such Depositary to such Depositary
or

                                       26
<PAGE>

another nominee of such Depositary or by such Depositary or any such nominee to
a successor Depositary for such series or a nominee of such successor
Depositary.

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.

If at any time the Depositary for the Securities of a series notifies the
Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be eligible under Section 3.03, the Company shall
appoint a successor Depositary with respect to the Securities of such series. If
a successor Depositary for the Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company's election pursuant to Section 3.01(vi) shall
no longer be effective with respect to the Securities of such series and the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive Securities of such series, will
authenticate and deliver Securities of such series of like tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of the Global Security or Securities representing such series in exchange for
such Global Security or Securities.

The Company may at any time and in its sole discretion determine that the
Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by such Global Security or Securities. In such
event, the Company will execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of definitive Securities of such
series, will deliver, Securities of such series of like tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of the Global Security or Securities representing such series in exchange for
such Global Security or Securities.

If specified by the Company pursuant to Section 3.01 with respect to a series of
Securities, the Depositary for such series of Securities may surrender a Global
Security for such series of Securities in exchange in whole or in part for
Securities of such series of like tenor and terms and in definitive form on such
terms as are acceptable to the Company, the Trustee and such Depositary.
Thereupon, the Company shall execute, and the Trustee upon receipt of a Company
Order for the authentication and delivery of definitive Securities of such
series, shall authenticate and deliver, without service charge:

(a) to the Depositary or to each Person specified by such Depositary a new
Security or Securities of the same series, of like tenor and terms and of any
authorized denomination as requested by such Person in aggregate principal
amount equal to and in exchange for such Person's beneficial interest in the
Global Security; and

(b) to such Depositary a new Global Security of like tenor and terms and in an
authorized denomination equal to the difference, if any, between the principal
amount of the surrendered Global Security and the aggregate principal amount of
Securities delivered to Holders thereof.

In any exchange provided for in any of the preceding three paragraphs, the
Company will execute and the Trustee, pursuant to a Company Order, will
authenticate and deliver, Securities (a) in definitive registered form in
authorized denominations, if the Securities of such series are issuable as
Registered Securities, (b) in definitive bearer form in authorized
denominations, with coupons attached, if the Securities of such series are
issuable as Bearer Securities or (c) as either Registered or Bearer Securities,
if the Securities of such series are issuable in either form; provided, however,

      that no definitive Bearer Security shall be delivered in exchange for a
      temporary

Global Security other than in accordance with the provisions of Sections 3.03
and 3.04.

Upon the exchange of Global Securities for Securities in definitive form, such
Global Securities shall be canceled by the Trustee. Registered Securities issued
in exchange for a Global Security pursuant to this Section 3.05 shall be
registered in such names and in such authorized denominations, and delivered to
such addresses, as the Depositary for such Global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee in writing. The Trustee shall deliver such Registered
Securities to the Persons in whose names such Securities are so registered or to
the Depositary. The Trustee shall deliver Bearer Securities issued in exchange
for a Global Security pursuant to this Section 3.05 to the Depositary or to the
Persons at such addresses, and in such authorized denominations, as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee in writing;
provided, however, that no definitive Bearer Security shall be delivered in
exchange for a temporary Global Security other than in accordance with the
provisions of Sections 3.03 and 3.04.

                                       27
<PAGE>

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

Unless otherwise provided in the Securities to be registered for transfer or
exchanged, no service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may (unless otherwise provided in such
Securities) 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 expressly provided in
this Indenture to be made at the Company's own expense or without expense or
without charge to Holders.

Neither the Company, the Security Registrar nor any Co-Security Registrar shall
be required (i) to issue, register the transfer of or exchange any Securities of
any series during a period beginning at the opening of business 15 days before
the day of selection of Securities of such series to be redeemed and ending at
the close of business on (A) if Securities of the series are issuable only as
Registered Securities, the day of the mailing of the relevant notice of
redemption of Registered Securities of such series so selected for redemption or
(B) if Securities of the series are issuable as Bearer Securities, the day of
the first publication of the relevant notice of redemption or, if Securities of
the series 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 or exchange of any Securities or portions thereof so
selected for redemption.

Notwithstanding anything herein to the contrary, the exchange of Bearer
Securities into Registered Securities shall be subject to applicable laws and
regulations in effect at the time of exchange; none of the Company, the Trustee
nor the Security Registrar shall exchange any Bearer Securities into Registered
Securities if it has received an Opinion of Counsel that as a result of such
exchanges the Company would suffer adverse consequences under the United States
federal income tax laws and regulations then in effect and the Company has
delivered to the Trustee a Company Order directing the Trustee not to make such
exchanges unless and until the Trustee receives a subsequent Company Order to
the contrary. The Company shall deliver copies of such Company Orders to the
Security Registrar.

SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Securities. If (i) any
mutilated Security or Security with a mutilated coupon is surrendered to the
Trustee or the Security Registrar, or if the Company, the Trustee and the
Security Registrar receive evidence to their satisfaction of the destruction,
loss or theft of any Security or coupon and (ii) there is delivered to the
Company, the Trustee and the Security Registrar such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
notice to the Company, the Trustee or the Security Registrar that such Security
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
mutilated, destroyed, lost or stolen Security or in exchange for the Security to
which a mutilated, destroyed, lost or stolen coupon appertains (with all
appurtenant coupons not mutilated, destroyed, lost or stolen), a new Security of
the same series and Stated Maturity and of like tenor and principal amount,
bearing a number not contemporaneously outstanding and, if applicable, with
coupons corresponding to the coupons appertaining thereto; provided, however ,
that any new Bearer Security will be delivered only in compliance with the
conditions set forth in Section 3.05.

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, pay such Security; provided, however, that
payment of principal of (and premium, if any) and any interest on Bearer
Securities shall be payable only at an office or agency located outside the
United States, and, in the case of interest, unless otherwise specified as
contemplated by Section 3.01, 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 exchange for any mutilated Security or in lieu of any destroyed,
lost or stolen Security, or in exchange for a Security with a mutilated,
destroyed, lost or stolen coupon, shall constitute an original additional
contractual obligation of the Company, whether or not the mutilated, destroyed,
lost or stolen Security and its coupons, if any, or the mutilated, 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 the same series and their coupons, if any, duly
issued hereunder.

                                       28
<PAGE>

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 3.07. Payment of Interest; Interest Rights Preserved. Unless otherwise
provided as contemplated by Section 3.01, interest on any Registered Security
which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall unless otherwise provided in such Security 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. Unless otherwise specified as contemplated by Section 3.01, 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
referred to in Section 3.05) 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. At the option of the
Company, payment of interest on any Registered Security may be made by check in
the currency designated for such payment pursuant to the terms of such
Registered Security mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or by wire transfer to an account
in such currency designated by such Person in writing not later than ten days
prior to the date of such payment.

Any interest on any Registered Security which 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 Holder on the
relevant Regular Record Date by virtue of his having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (i) or clause (ii) below.

(i) The Company may elect to make payments of any Defaulted Interest to the
Persons in whose names any such Registered Securities (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 and
the date of the proposed payment, and at the same time the Company shall deposit
with the Trustee an amount of money 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 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 nor 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 at his address as it appears in the
Security Register, not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special Record
Date therefor having been mailed as aforesaid, such Defaulted Interest shall be
paid to the Persons in whose names such Registered Securities (or their
respective Predecessor Securities) are registered on such Special Record Date
and shall no longer be payable pursuant to the following clause (ii). 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 of payment of Defaulted Interest, such Bearer Security shall be
surrendered without the coupon relating to such proposed date for payment and
Defaulted Interest will not be payable on such proposed date for 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.

(ii) The Company may make payment of any Defaulted Interest in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Securities with respect to which there exists such default 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 payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, 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.

Subject to the limitations set forth in Section 5.02, the Holder of any coupon
appertaining to a Bearer Security shall be entitled to receive the interest
payable on such coupon upon presentation and surrender of such coupon on or
after the Interest Payment Date of such coupon at an office or agency maintained
for such purpose pursuant to Section 5.02.

SECTION 3.08. Persons Deemed Owners. Title to any Bearer Security, any coupons
appertaining thereto and any temporary Global Security shall pass by delivery.

                                       29
<PAGE>

Prior to due presentment for registration of transfer of any Registered
Security, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered as the owner of
such Security for the purpose of receiving payment of principal of, premium, if
any, and (subject to Section 3.07) interest on such Security, and for all
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

The Company, the Trustee and any agent of the Company or the Trustee may treat
the bearer of any Bearer Security and the bearer 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 neither the Company, the Trustee nor any
agent of the Company or the Trustee shall be affected by notice to the contrary.
None of the Company, the Trustee, any Paying Agent, any Authenticating Agent or
the Security Registrar will have the responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership
interest of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest, and they shall be fully
protected in acting or refraining from acting on any such information provided
by the Depositary.

SECTION 3.09. Cancellation. Unless otherwise provided with respect to a series
of Securities, all Securities and coupons surrendered for payment, registration
of transfer, exchange, repayment or redemption shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee. All Securities so
delivered or surrendered directly to the Trustee for any such purpose shall be
promptly cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and all Securities
so delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture or such
Securities. All cancelled Securities or coupons held by the Trustee shall be
destroyed by the Trustee and the Trustee shall deliver a certificate of such
destruction to the Company.

SECTION 3.10. Computation of Interest. Interest on the Securities of each series
shall be computed as shall be specified as contemplated by Section 3.01.

SECTION 3.11. Form of Certification. Unless otherwise provided pursuant to
Section 3.01:

(i) Whenever any provision of this Indenture or the forms of Securities
contemplate that certification be given by a Person entitled to receive a Bearer
Security, such certification shall be provided substantially in the form of
Exhibit A hereto, with only such changes as shall be approved by the Company.

(ii) Whenever any provision of this Indenture or the forms of Securities
contemplate that certification be given by Euroclear and CEDEL S.A. in
connection with the exchange of a portion of a temporary Global

Security, such certification shall be provided substantially in the form of
Exhibit B hereto, with only such changes as shall be approved by the Company.

(iii) Whenever any provision of the Indenture or the forms of Securities
contemplate that certification be given by Euroclear and CEDEL S.A. in
connection with payment of interest with respect to a temporary Global Security
prior to the related Global Exchange Date, such certification shall be provided
substantially in the form of Exhibit C hereto, with only such changes as shall
be approved by the Company.

(iv) Whenever any provision of the Indenture or the forms of Securities
contemplate that certification be given by a beneficial owner of a portion of a
temporary Global Security in connection with payment of interest with respect to
a temporary Global Security prior to the related Global Exchange Date, such
certification shall be provided substantially in the form of Exhibit D hereto,
with only such changes as shall be approved by the Company.

SECTION 3.12. Judgments. The Company may provide, pursuant to Section 3.01, for
the Securities of any series that, to the fullest extent possible under
applicable law and except as may otherwise be specified as contemplated in
Section 3.01, (a) the obligation, if any, of the Company to pay the principal of
(and premium, if any) and interest of the Securities of any series and any
appurtenant coupons in a Foreign Currency, composite currency or Dollars (the
"Designated Currency") as may be specified pursuant to Section 3.01 is of the
essence and agrees that judgments in respect of such Securities shall be given
in the Designated Currency; (b) the obligation of the Company to make payments
in the Designated Currency of the principal of (and premium, if any) and
interest on such Securities and any appurtenant coupons shall, notwithstanding
any payment in any other currency (whether pursuant to a judgment or otherwise),
be discharged only to the extent of the amount in the Designated Currency that
the Holder receiving such payment may, in accordance with normal banking
procedures, purchase with the sum paid in such other currency (after any premium
and cost of exchange) in the country of issue of the Designated Currency in the
case of Foreign Currency or Dollars or in the international banking community in
the case of a composite currency on the Business Day immediately following the
day on which such Holder receives such payment; (c) if the amount in the
Designated Currency that may be so purchased for any reason falls short of the
amount originally due, the Company shall pay such additional amounts as may be
necessary to compensate for such shortfall;

                                       30
<PAGE>

and (d) any obligation of the Company not discharged by such payment shall be
due as a separate and independent obligation and, until discharged as provided
herein, shall continue in full force and effect.

                                  ARTICLE FOUR

                            REDEMPTION OF SECURITIES

SECTION 4.01. Applicability of Article. Securities of any series which are
redeemable before their Stated Maturity shall be redeemable in accordance with
their terms and, except as otherwise specified as contemplated by Section 3.01
for Securities of any series, in accordance with this Article.

SECTION 4.02. Election To Redeem; Notice to Trustee. The election of the Company
to redeem any Securities redeemable at the option of the Company shall be
evidenced by an Officers' Certificate. In case of any redemption at the election
of the Company of less than all the Securities of any series, the Company shall,
at least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee and the
Security Registrar 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 (i) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (ii)
pursuant to an election of the Company which is subject to a condition specified
in the terms of such Securities, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

SECTION 4.03. Selection by Security Registrar of Securities To Be Redeemed. If
less than all the Securities of any series 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 Security Registrar from the
Outstanding Securities of such series having such terms not previously called
for redemption, by such method as the Security Registrar shall deem fair and
appropriate and which may provide for the selection for redemption of portions
of the principal amount of Securities of such series of a denomination equal to
or larger than the minimum authorized denomination for Securities of such
series. Unless otherwise provided by the terms of the Securities of any series
so selected for partial redemption, the portions of the principal of Securities
of such series so selected for partial redemption shall be, in the case of
Registered Securities, equal to $1,000 or an integral multiple thereof or, in
the case of Bearer Securities, equal to $5,000 or an integral multiple thereof,
and the principal amount of any such Security which remains outstanding shall
not be less than the minimum authorized denomination for Securities of such
series.

The Security Registrar shall promptly notify the Company, the Trustee and the
Co-Security Registrar, if any, in writing of the Securities selected for
redemption and, in the case of any Security 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 of such Security which has been or is to be redeemed.

SECTION 4.04. Notice of Redemption. Notice of redemption shall be given in the
manner provided in Section 1.06, not less than 30 nor more than 60 days prior to
the Redemption Date, to each Holder of Securities to be redeemed.

All notices of redemption shall state:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) if less than all Outstanding Securities of any series having the same
terms are to be redeemed, the identification (and, in the case of partial
redemption, the respective principal amounts) of the particular Securities to be
redeemed;

(iv) that on the Redemption Date the Redemption Price will become due and
payable upon each such Security to be redeemed, and that interest, if any,
thereon shall cease to accrue on and after said date;

(v) the place or places where such Securities, together in the case of Bearer
Securities with all remaining coupons appertaining thereto, if any, maturing
after the Redemption Date, are to be surrendered for payment of the Redemption
Price;

(vi) that the redemption is for a sinking fund, if such is the case; and

(vii) the CUSIP number or the Euroclear or the CEDEL reference number (or any
other number used by a Depositary to identify such Securities), if any, of the
Securities to be redeemed.

                                       31
<PAGE>

A notice of redemption published as contemplated by Section 1.06 need not
identify particular Registered Securities to be redeemed.

Notice of redemption of Securities to be redeemed at the election of the Company
shall be given by the Company or, on Company Request, by the Trustee in the name
and at the expense of the Company.

SECTION 4.05. Deposit of Redemption Price. At or prior to the opening of
business on any Redemption Date, the Company shall deposit or cause to be
deposited 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
5.03) an amount of money sufficient to pay the Redemption Price of all the
Securities which are to be redeemed on that date; provided, however, that
deposits with respect to Bearer Securities shall be made with a Paying Agent or
Paying Agents located outside the United States except as otherwise provided in
Section 5.02, unless otherwise specified as contemplated by Section 3.01.

SECTION 4.06. 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 and from and after such date (unless the Company shall default in the
payment of the Redemption Price) such Securities shall 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 Securities for redemption in accordance with said notice, such
Securities shall be paid by the Company at the Redemption Price; 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 and, unless otherwise
specified as contemplated by Section 3.01, only upon presentation and surrender
of coupons for such interest. 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 on the close of business on the relevant Regular Record Dates
according to their terms and the provisions of Section 3.07.

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 and, unless otherwise specified as contemplated by
Section 3.01, only upon presentation and surrender of those coupons.

If any Security called for redemption shall not be paid upon surrender thereof
for redemption, the principal shall, until paid, bear interest from the
Redemption Date at the rate borne by such Security, or as otherwise provided in
such Security.

SECTION 4.07. Securities Redeemed in Part. Any Security which is to be redeemed
only in part shall be surrendered at the office or agency of the Company in a
Place of Payment therefor (with, if the Company or the Security Registrar so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder of such Security or his attorney duly authorized in writing), and the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and Stated Maturity, containing identical terms and conditions,
of any authorized denominations 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.

SECTION 4.08. Redemption Suspended During Event of Default. The Trustee shall
not redeem any Securities (unless all Securities then Outstanding are to be
redeemed) or commence the giving of any notice of redemption of Securities
during the continuance of any Event of Default known to the Trustee, except that
where the giving of notice of redemption of any Securities shall theretofore
have been made, the Trustee shall, subject to the provisions of Section 14.04,
redeem such Securities, provided funds are deposited with it for such purpose.
Subject to the rights of the holders of Senior Indebtedness and creditors in
respect of General Obligations, except as aforesaid, any moneys theretofore or
thereafter received by the Trustee shall, during the continuance of such Event
of Default, be held in trust for the benefit of the Holders and applied in the
manner set forth in Section 7.06; provided, however, that in case such Event of
Default shall have been waived as provided herein or otherwise cured, such
moneys shall thereafter be held and applied in accordance with the provisions of
this Article.

                                  ARTICLE FIVE

                                    COVENANTS

SECTION 5.01. Payment of Principal, Premium and Interest. The Company covenants
and agrees for the benefit of each series of Securities that it will duly and
punctually pay the principal of, premium, if any, and interest on the Securities
of such series in accordance with the terms of the Securities of such series,
any coupons appertaining thereto and this Indenture. Unless otherwise specified
as contemplated by Section 3.01 with respect to any series of Securities, any
interest due on Bearer Securities on or before

                                       32
<PAGE>

Maturity shall be payable only outside the United States upon presentation and
surrender of the several coupons for such interest installments as are evidenced
thereby as they severally mature.

SECTION 5.02. Maintenance of Office or Agency. If Securities of a series are
issuable only as Registered Securities, the Company will 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, 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. The Company will give prompt
written notice to the Trustee of the location, and of any change in the
location, of such office or agency. If Securities of a series may be 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, 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, (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
5.04); provided, however, that if the Securities of that series are listed on
The International Stock Exchange of the United Kingdom and the Republic of
Ireland Limited or 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 London
or 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 such 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 any such office or agency. If at any time the Company shall fail to
maintain any such required office or agency in respect of any series of
Securities or shall fail to furnish the Trustee with the address thereof, such
presentations, and surrenders of Securities of that series may be made and
notices and demands may be made or served at the Principal 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 5.04) at the place specified for the purpose as contemplated by
Section 3.01, and the Company hereby appoints the Trustee as its agent to
receive such respective presentations, surrenders, notices and demands.

Except as otherwise provided in the form of Bearer Security of any particular
series pursuant to the provisions of this Indenture, no payment of principal,
premium or interest on 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, payment of principal of and any premium and
interest denominated in Dollars (including additional amounts payable in respect
thereof) on any Bearer Security may be made at an office or agency of, and
designated by, the Company located in the United States if (but only if) payment
of the full amount of such principal, premium, interest or additional amounts in
Dollars at all offices 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 similar restrictions and the Trustee receives
an Opinion of Counsel that such payment within the United States is legal.
Unless otherwise provided as contemplated by Section 3.01 with respect to any
series of Securities, at the option of the Holder of any Bearer Security or
related coupon, payment may be made by check in the currency designated for such
payment pursuant to the terms of such Bearer Security presented or mailed to an
address outside the United States or by transfer to an account in such currency
maintained by the payee with a bank located outside the United States.

The Company may also 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 specified above in this Section and
may constitute and appoint one or more Paying Agents for the payment of such
Securities, in one or more other cities, and may from time to time rescind such
designations and appointments; provided, however, that no such designation,
appointment or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in each Place of Payment 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 and until the Company
rescinds one or more such appointments, the Company hereby appoints Citibank,
N.A., as its Paying Agent in the City of New York with respect to all series of
Securities having a Place of Payment in the City of New York.

SECTION 5.03. Money for Security Payments To Be Held in Trust. If the Company
shall at any time act as its own Paying Agent for any series of Securities, it
will, on or before each due date of the principal of, premium, if any, or
interest on any of the Securities of such series and any appurtenant coupons,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal, premium or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and will promptly notify the Trustee of its action or failure so to
act.

Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, at or prior to the opening of business on each due date of
the principal of, premium, if any, or interest on any Securities of such series
and any appurtenant

                                       33
<PAGE>

coupons, deposit with a Paying Agent a sum sufficient to pay the principal,
premium or interest so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal, premium or interest, 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 for any series
of Securities 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:

(i) hold all sums held by it for the payment of principal of, premium, if any,
or interest on Securities of such series and any appurtenant coupons 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;

(ii) give the Trustee notice of any default by the Company (or any other obligor
upon the Securities of such series) in the making of any payment of principal,
premium or interest on the Securities of such series or any appurtenant coupons;
and

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

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

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, premium, if any, or
interest on any Security of any series or any appurtenant coupons and remaining
unclaimed for two years after such principal, premium or interest has become due
and payable shall be paid to the Company on Company Request, or (if then held by
the Company) shall be discharged from such trust, and the Holder of such
Security or any coupon appertaining thereto shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, 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 in each Place of Payment, 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 5.04. Additional Amounts. If the Securities of a series provide for the
payment of additional amounts, the Company will pay to the Holder of any
Security of any series or any coupon appertaining thereto additional amounts as
provided therein. Whenever in this Indenture there is mentioned, in any context,
the payment of the principal of (or premium, if any) 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 for in this Section to the extent that, in such context,
additional amounts are, were or would be payable in respect thereof pursuant to
the provisions of this Section 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.

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 premium,
if any) is made), and at least 10 days prior to each date of payment of
principal (and premium, if any) 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 premium, if any) or interest on the Securities of
that series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described in the Securities of
that series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or coupons and the Company will
pay to the Trustee or such Paying Agent the additional amounts required by this
Section. 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 in reliance on any
Officers' Certificate furnished pursuant to this Section.

SECTION 5.05. Statement as to Compliance. The Company will deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company, an
Officers' Certificate (provided, however, that one of the signatories of which
shall be the Company's principal executive officer, principal financial officer
or principal accounting officer) stating, as to each signer thereof, that:

                                       34
<PAGE>

(i) a review of the activities of the Company during such year and of
performance under this Indenture and under the terms of the Securities has been
made under his supervision; and

(ii) to the best of his knowledge, based on such review, (a) the Company has
fulfilled all its obligations and complied with all conditions and covenants
under this Indenture and under the terms of the Securities throughout such year,
or, if there has been a default in the fulfillment of any such obligation,
condition or covenant specifying each such default known to him and the nature
and status thereof, and (b) no event has occurred and is occurring which is, or
after notice or lapse of time or both would become, a Default, or if such an
event has occurred and is continuing, specifying such event known to him and the
nature and status thereof.

For purposes of this Section, compliance or default shall be determined without
regard to any period of grace or requirement of notice provided for herein.

SECTION 5.06. Maintenance of Corporate Existence, Rights and Franchises. So long
as any of the Securities shall be Outstanding, the Company will do or cause to
be done all things necessary to preserve and keep in full force and effect its
corporate existence, rights and franchises to carry on its business; provided,
however, that nothing in this Section 5.06 shall (i) require the Company to
preserve any such right or franchise if the Board of Directors shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and that the loss thereof is not disadvantageous in any
material respect to the Holders, (ii) prevent any consolidation or merger of the
Company, or any conveyance or transfer of its property and assets substantially
as an entirety to any person, permitted by Article Ten, (iii) prevent the
liquidation or dissolution of the Company after any conveyance or transfer of
its property and assets substantially as an entirety to any person permitted by
Article Ten.

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 6.01. Company To Furnish Trustee Names and Addresses of Holders. The
Company will furnish or cause to be furnished to the Trustee (i) semiannually,
not more than 10 days after each March 1 and September 1, a list, in such form
as the Trustee may reasonably require, containing all the information in the
possession or control of the Company, any of its Paying Agents (other than the
Trustee) or the Security Registrar, if other than the Trustee, as to the names
and addresses of the Holders of Securities as of the preceding February 15 and
August 15, as the case may be, and (ii) at such other times as the Trustee may
request in writing, within 30 days after receipt by the Company of any such
request, a list of similar form and content as of a date not more than 15 days
prior to the time such list is requested to be furnished; provided, however,
that if and so long as the Trustee is the Security Registrar for Securities of a
series, no such list need be furnished with respect to such Series of
Securities.

SECTION 6.02. Preservation of Information; Communications to Holders.

(i) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders of Securities contained in the
most recent list furnished to the Trustee as provided in Section 6.01 and the
names and addresses of Holders of Securities received by the Trustee in its
capacity as the Security Registrar, if so acting. The Trustee may destroy any
list furnished to it as provided in Section 6.01 upon receipt of a new list so
furnished.

(ii) If three or more Holders of Securities of any series (hereinafter referred
to as "applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Security of such series
for a period of at least six months preceding the date of such application, and
such application states that the applicants desire to communicate with other
Holders of Securities of such series or with the Holders of all Securities with
respect to their rights under this Indenture or under such Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, at its election, either:

(a) afford such applicants access to the information preserved at the time by
the Trustee in accordance with Section 6.02(i); or

(b) inform such applicants as to the approximate number of Holders of Securities
of such series or all Securities, as the case may be, whose names and addresses
appear in the information preserved at the time by the Trustee in accordance
with Section 6.02(i), and as to the approximate cost of mailing to such Holders
the form of proxy or other communication, if any, specified in such application.

If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder of a Security of such series or all Holders of Securities,
as the case may be, whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 6.02(i), a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless, within five days after such tender, the Trustee shall mail
to such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interests of the Holders
of Securities of such series or all Securities, as the case may be, or would be
in violation of applicable law. Such written

                                       35
<PAGE>

statement shall specify the basis of such opinion. If the Commission, after
opportunity for a hearing upon the objections specified in the written statement
so filed, shall enter an order refusing to sustain any of such objections or if,
after the entry of an order sustaining one or more of such objections, the
Commission shall find, after notice and opportunity for hearing, that all the
objections so sustained have been met and shall enter an order so declaring, the
Trustee shall mail copies of such material to all such Holders of Securities
with reasonable promptness after the entry of such order and the renewal of such
tender; otherwise, the Trustee shall be relieved of any obligation or duty to
such applicants respecting their application.

(iii) Every Holder of Securities, by receiving and holding the same, agrees with
the Company and the Trustee that neither the Company nor the Trustee shall be
held accountable by reason of the disclosure of any such information as to the
names and addresses of the Holders of Securities in accordance with Section
6.02(ii), regardless of the source from which such information was derived, and
that the Trustee shall not be held accountable by reason of mailing any material
pursuant to a request made under Section 6.02(ii).

SECTION 6.03. Reports by Trustee. (i) Within 60 days after May l of each year
commencing with the year 1996, the Trustee shall mail to each Holder reports
concerning the Trustee and its action under the Indenture as may be required
pursuant to the Trust Indenture Act if and to the extent and in the manner
provided pursuant thereto.

(ii) Reports pursuant to this Section shall be transmitted by mail

(1) to all Holders of Registered Securities, as their names and addresses appear
in the Security Register and (2) to such Holders of Bearer Securities as have,
within the two years preceding such transmission, filed their names and
addresses with the Trustee for that purpose, and (3) except in the cases of
reports under Section 313(b)(2) of the Trust Indenture Act, to each Holder of a
Security of any series whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 6.02(i).

(iii) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each securities exchange upon which any
Securities are listed, and also with the Commission. The Company will notify the
Trustee when any Securities are listed on any securities exchange.

SECTION 6.04. Reports by Company. The Company will:

(i) file with the Trustee, within 15 days after the Company is required to file
the same with the Commission, copies of the annual reports and of the
information, documents and other reports (or copies of such portions of any of
the foregoing as the Commission may from time to time by rules and regulations
prescribe) which the Company may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company
is not required to file information, documents or reports pursuant to either of
said Sections, then it will file with the Trustee and the Commission, in
accordance with rules and regulations prescribed from time to time by the
Commission, such of the supplementary and periodic information, documents and
reports which may be required pursuant to Section 13 of the Exchange Act in
respect of a security listed and registered on a national securities exchange as
may be prescribed from time to time in such rules and regulations;

(ii) file with the Trustee and the Commission, in accordance with rules and
regulations prescribed from time to time by the Commission, such additional
information, documents and reports with respect to compliance by the Company
with the conditions and covenants of this Indenture as may be required from time
to time by such rules and regulations; and

(iii) transmit by mail to Holders of Securities, in the manner and to the extent
provided in Section 6.03(ii), within 30 days after the filing thereof with the
Trustee, such summaries of any information, documents and reports required to be
filed by the Company pursuant to paragraphs (i) and

(ii) of this Section as may be required by rules and regulations prescribed from
time to time by the Commission.

                                    REMEDIES

SECTION 7.01. Events of Default. "Event of Default", with respect to any series
of Securities, wherever used herein, means any one of the following events
(whatever the reason for such Event of Default and whether 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), unless it is either inapplicable to a
particular series or it is specifically deleted or modified in the supplemental
indenture or Board Resolution under which such series of Securities is issued or
in the form of Security for such series:

(i) the entry of a decree or order by a court having jurisdiction in the
premises granting relief in respect of the Company in an involuntary case under
the Federal Bankruptcy Code, adjudging the Company a bankrupt, or approving as
properly filed a petition seeking reorganization, arrangement, adjustment or
composition of or in respect of the Company under the Federal Bankruptcy Code or
any other applicable Federal or State bankruptcy, insolvency or similar law, or
appointing a receiver, liquidator, custodian,

                                       36
<PAGE>

assignee, trustee, sequestrator (or other similar official) of the Company, or
of substantially all of its properties, or ordering the winding up or
liquidation of its affairs under any such law, and the continuance of any such
decree or order unstayed and in effect for a period of 60 consecutive days; or

(ii) the institution by the Company of proceedings to be adjudicated a bankrupt,
or the consent of the Company to the institution of bankruptcy proceedings
against it, or the filing by the Company of a petition or answer or consent
seeking reorganization or relief under the Federal Bankruptcy Code or any other
applicable Federal or State bankruptcy, insolvency or similar law, or the
consent by the Company to the filing of any such petition or to the appointment
of a receiver, liquidator, custodian, assignee, trustee, sequestrator (or other
similar official) of the Company, or of substantially all of its properties
under any such law; or

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

SECTION 7.02. Acceleration of Maturity; Rescission and Annulment. If an Event of
Default with respect to any series of Securities for which there are Securities
Outstanding occurs and is continuing, then, and in every such case, the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of such series may declare the principal of all the Securities of
such series (or, if the Securities of that series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of that series) to be immediately due and payable, by a notice in writing
to the Company (and to the Trustee if given by Holders), and upon any such
declaration the same shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities
of any series has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in principal amount of the Outstanding
Securities of such series, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences, and any Event of
Default giving rise to such declaration shall not be deemed to have occurred,
if:

(i) the Company has paid or deposited with the Trustee a sum sufficient to pay:

(a) all overdue installments of interest on all Securities of such series;

(b) the principal of and premium, if any, on any Securities of such series which
have become due otherwise than by such declaration of acceleration and interest
thereon at the rate or rates prescribed therefor by the terms of the Securities
of such series;

(c) to the extent that payment of such interest is lawful, interest upon overdue
installments of interest at the rate or rates prescribed therefor by the terms
of the Securities of such series; and (d) all sums paid or advanced by the
Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, the Security Registrar, any Paying Agent, and their
agents and counsel and all other amounts due the Trustee under Section 8.07.

(ii) all other Defaults with respect to Securities of that series, other than
the nonpayment of the principal of Securities of that series which have become
due solely by such declaration of acceleration, have been cured or waived as
provided in Section 7.13.

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

SECTION 7.03. Collection of Indebtedness and Suits for Enforcement by Trustee.
The Company covenants that if:

(i) default is made in the payment of any installment of interest on any
Security of any series when such interest becomes due and payable and such
default continues for a period of 30 days, or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holder of any such Security or coupon appertaining thereto, if any, the whole
amount then due and payable on any such Security or coupon for principal,
premium, if any, and interest, with interest upon the overdue principal and
premium, if any, and (to the extent that payment of such interest shall be
lawful) upon overdue installments of interest, at the rate or rates prescribed
therefor by the terms of any such Security; and, in addition thereto, such
further amount as shall be sufficient to cover the reasonable costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel and any other amounts due
the Trustee under Section 8.07.

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 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, wherever
situated.

                                       37
<PAGE>

If a Default with respect to any series of Securities 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 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 7.04. 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 any Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee shall
have made any demand on the Company for the payment of overdue principal,
premium, 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 of principal, premium, if
any, and interest 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
any other amounts due the Trustee under Section 8.07) 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 receiver, assignee,
trustee, liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder 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, its agents and counsel, and any other amounts due the Trustee under
Section 8.07.

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 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 7.05. Trustee May Enforce Claims Without Possession of Securities. All
rights of action and claims under this Indenture or under the Securities of any
series, or coupons (if any) appertaining thereto, may be prosecuted and enforced
by the Trustee without the possession of any of the Securities of such series or
coupons appertaining thereto 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 and
any other amounts due the Trustee under Section 8.07, be for the ratable benefit
of the Holders of the Securities of such series and coupons appertaining thereto
in respect of which such judgment has been recovered.

SECTION 7.06. Application of Money Collected. Any money collected by the Trustee
with respect to a series of Securities 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, premium, if any, or
interest, upon presentation of the Securities of such series or coupons
appertaining thereto, if any, 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 under Section 8.07;

SECOND: To the payment of the amounts then due and unpaid upon the Securities of
such series and coupons for principal, premium, if any, and interest, 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 amounts due and
payable on Securities of such series and coupons, if any, for principal,
premium, if any, and interest, respectively. The Holders of each series of
Securities denominated in ECU, any other composite currency or a Foreign
Currency and any matured coupons relating thereto shall be entitled to receive a
ratable portion of the amount determined by the Exchange Rate Agent by
converting the principal amount Outstanding of such series of Securities and
matured but unpaid interest on such series of Securities in the currency in
which such series of Securities is denominated into Dollars at the Exchange Rate
as of the date of declaration of acceleration of the Maturity of the Securities;
and

THIRD: The balance, if any, to the Person or Persons entitled thereto.

SECTION 7.07. Limitation on Suits. No Holder of any Security of any series or
any related coupons 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:

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

                                       38
<PAGE>

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

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

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

(v) 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 such series;

it being understood and intended that no one or more Holders of Securities of
such series 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 Holders of Securities of such series or to obtain or to seek
to obtain priority or preference over any other 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 the Holders of Securities of such series.

The following events shall be "Defaults" with respect to any series of
Securities under this Indenture:

(a) an Event of Default with respect to such series specified in Section 7.01;
or

(b) default in the payment of the principal of or premium, if any, on any
Security of such series at its Maturity; or

and when the same shall become due and payable, and continuance of such default
for a period of 90 days; or

(d) failure on the part of the Company duly to observe or perform any of the
other covenants or agreements on its part in the Securities of such series or in
this Indenture and continuance of such failure for a period of 90 days after the
date on which written notice of such failure, requiring the Company to remedy
the same and stating that such notice is a "Notice of Default" hereunder, shall
have been given by registered mail to the Company by the Trustee, or to the
Company and the Trustee by the holders of at least 25% in aggregate principal
amount of the Securities of such series at the time Outstanding; or

(e) any other Default provided with respect to Securities of that Series.

SECTION 7.08. Unconditional Right of Holders To Receive Principal, Premium and
Interest. 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, premium, if any, and
(subject to Section 3.07) interest on such Security or payment of such coupon on
the respective Stated Maturities expressed in such Security or coupon (or, in
the case of redemption or repayment on the Redemption Date or Repayment Date)
and to institute suit for the enforcement of such payment, and such rights shall
not be impaired without the consent of such Holder.

SECTION 7.09. 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 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 7.10. Rights and Remedies Cumulative. Except as otherwise provided with
respect to the replacement or payment of mutilated, lost, destroyed or stolen
Secur-ities or coupons in the last paragraph of Section 3.06, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders 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 7.11. 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 Default shall impair any such right or remedy or constitute a
waiver of any such 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, as the case may be.

SECTION 7.12. Control by Holders. The Holders of 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

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

(ii) the Trustee shall not determine that the action so directed would be
unjustly prejudicial to the Holders not taking part in such direction,

(iii) subject to the provisions of Section 8.01, the Trustee shall have the
right to decline to follow any such direction if the Trustee in good faith
shall, by a Responsible Officer or Officers of the Trustee, determine that the
proceeding so directed would involve the Trustee in personal liability, and

(iv) the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.

SECTION 7.13. Waiver of Past Defaults. The Holders of 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 waive any past default hereunder and its
consequences, except a default not theretofore cured

(i) in the payment of the principal of, premium, if any, or interest on any
Security of such series, or

(ii) 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 Default or Event of Default arising therefrom
shall be deemed to have been cured, for every purpose of the Securities of such
series under this Indenture; but no such waiver shall extend to any subsequent
or other default or impair any right consequent thereon.

SECTION 7.14. 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, suffered or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Company, 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 of any series,
or to any suit instituted by any Holder of Securities or coupons for the
enforcement of the payment of the principal of, premium, if any, or interest on
any Security or payment of any coupon on or after the respective Stated
Maturities expressed in such Security or coupon (or, in the case of redemption
or repayment, on or after the Redemption Date or Repayment Date).

SECTION 7.15. Waiver of 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 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.

                                  ARTICLE EIGHT

                                   THE TRUSTEE

SECTION 8.01. Certain Duties and Responsibilities. (i) Except during the
continuance of a Default with respect to any series of Securities:

(a) the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture with respect to Securities of such
series, and no implied covenants or obligations shall be read into this
Indenture against the Trustee with respect to such series; and

(b) in the absence of bad faith on its part, the Trustee may conclusively rely
with respect to such series, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture;
but in the case of any such certificate or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall be under a duty to examine the same to determine whether or not they
conform as to form to the requirements of the Indenture.

                                       40
<PAGE>

(ii) In case a Default with respect to any series of Securities has occurred and
is continuing, the Trustee shall exercise such of the rights and powers vested
in it by this Indenture with respect to such series, and use the same degree of
care and skill in their exercise, as a prudent person would exercise or use
under the circumstances in the conduct of his or her own affairs.

(iii) No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act,
or its own wilful misconduct, except that

(a) this Subsection shall not be construed to limit the effect of Subsection (i)
of this Section;

(b) the Trustee shall not be liable for any error or judgment made in good faith
by a Responsible Officer, unless it shall be proved that the Trustee was
negligent in ascertaining the pertinent facts; (c) the Trustee shall not be
liable with respect to any action taken, suffered or omitted to be taken by it
in good faith in accordance with the direction of the Holders of a majority in
principal amount of the Outstanding Securities of any series relating to the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture with respect to Securities of such series; and

(d) no provision of this Indenture shall require the Trustee 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.

(iv) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

SECTION 8.02. Notice of Default. Within 90 days after the occurrence of any
default hereunder with respect to Securities of any series, the Trustee shall
transmit by mail to all Holders of Securities of such series entitled to receive
reports pursuant to Section 6.03(ii) notice of such default hereunder known to
the Trustee, unless such default shall have been cured or waived; provided,
however, that, except in the case of a default in the payment of the principal
of, premium, if any, or interest on any Security of such series, or any related
coupons or in the payment of any sinking fund installment with respect to
Securities of such series the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determines that the withholding of such notice is in the interests of the
Holders of Securities of such series; and provided further that in the case of
any default of the character specified in Section 7.07(d) with respect to
Securities of such series, no such notice to Holders of Securities of such
series shall be given until at least 90 days after the occurrence thereof. For
the purpose of this Section, the term "default", with respect to Securities of
any series, means any event which is, or after notice or lapse of time, or both,
would become, a Default or an Event of Default with respect to Securities of
such series.

SECTION 8.03. Certain Rights of Trustee. Except as otherwise provided in Section
8.01:

(i) 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, note or other paper or
document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

(ii) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

(iii) 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;

(iv) 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;

(v) 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 pursuant to this Indenture, unless such Holders shall have offered to
the Trustee reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction;

(vi) 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, security or other
paper or document, but the Trustee, in its discretion, may make further inquiry
or investigation into such facts or matters as it may see fit, and, if the
Trustee shall determine to make such further inquiry or investigation, it shall
be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney and, if so requested to do so by any of the
Holders, at the sole cost and expense of the Holders;

                                       41
<PAGE>

(vii) 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

(viii) in the event that the Trustee is also acting as Paying Agent,
Authenticating Agent or Security Registrar hereunder, the rights and protections
afforded to the Trustee pursuant to this Article Eight shall also be afforded to
such Paying Agent, Authenticating Agent or Security Registrar.

SECTION 8.04. Not Responsible for Recitals or Issuance of Securities. The
recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes responsibility for
their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities. The Trustee shall not be
accountable for the use or application by the Company of Securities or the
proceeds thereof.

SECTION 8.05. May Hold Securities. The Trustee, any Authenticating Agent, any
Paying Agent, the Security Registrar or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 8.08 and 8.13, may otherwise deal with the Company with
the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Security Registrar or such other agent.

SECTION 8.06. 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 in writing with the Company.

SECTION 8.07. Compensation and Reimbursement. The Company agrees

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

(ii) except as otherwise expressly provided herein, to reimburse the 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

(iii) to indemnify the Trustee for, and to hold it harmless against, any loss,
liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this
trust, 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.

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, premium, if any, or interest on particular
Securities.

When the Trustee incurs expenses or renders services in connection with an Event
of Default specified in 7.01, the expenses (including the reasonable fees and
expenses of its counsel) and the compensation for the services are intended to
constitute expenses of administration under any applicable bankruptcy,
insolvency or other similar law.

The obligations of the Company set forth in this Section 8.07 and any lien
arising hereunder shall survive the resignation or removal of any Trustee, the
discharge of the Company's obligations pursuant to Article Eleven of this
Indenture and the termination of this Indenture and the repayment of the
Securities whether at the Stated Maturity or otherwise.

SECTION 8.08. Disqualification; Conflicting Interests. If the Trustee has or
shall acquire a conflicting interest within the meaning of Section 310 of the
Trust Indenture Act, the Trustee shall either eliminate such conflicting
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by the Trust Indenture Act, the Trustee shall not be deemed to have a
conflicting interest with respect to the Securities of any series by virtue of
being Trustee with respect to the Securities of any particular series of
Securities other than that series.

SECTION 8.09. Corporate Trustee Required; Eligibility. There shall at all times
be a Trustee with respect to each series of Securities hereunder which shall be
a corporation organized and doing business under the laws of the United States
of America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $5,000,000, subject to supervision or examination by Federal or
State authority; provided, however, that if Section 310( a) of the Trust
Indenture Act or the rules and regulations of the Commission under the Trust
Indenture Act at any time permit a corporation organized and doing business
under the laws of any other jurisdiction to serve as trustee of an indenture
qualified under the Trust

                                       42
<PAGE>

Indenture Act, this Section 8.09 shall be automatically deemed amended to permit
a corporation organized and doing business under the laws of any such
jurisdiction to serve as Trustee hereunder. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid 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. Neither the Company nor any person directly or
indirectly controlling, controlled by or under common control with the Company
may serve as Trustee. If at any time the Trustee with respect to any series of
Securities 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 8.10. Resignation and Removal; Appointment of Successor. (i) 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 under Section 8.11.

(ii) The Trustee may resign with respect to any series of Securities at any time
by giving written notice thereof to the Company. If an instrument of acceptance
by a successor Trustee shall not have been delivered to the resigning 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 with respect to Securities of such series.

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

(iv) If at any time:

(a) the Trustee shall fail to comply with Section 8.08 with respect to any
series of Securities after written request therefor by the Company or by any
Holder who has been a bona fide Holder of a Security of such series for at least
six months, or

(b) the Trustee shall cease to be eligible under Section 8.09 with respect to
any series of Securities and shall fail to resign after written request therefor
by the Company or by any Holder of Securities of such series, or

(c) the Trustee shall become incapable of acting with respect to any series of
Securities 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, (1) the
Company by a Board Resolution may remove the Trustee with respect to such
series, or (2) subject to Section 7.14, any Holder 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 removal of the Trustee and the appointment of a successor
Trustee with respect to such series.

(v) If the Trustee shall resign, be removed or become incapable of acting with
respect to any series of Securities, or if a vacancy shall occur in the office
of Trustee with respect to any series of Securities for any cause, the Company,
by 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) and shall
comply with the applicable requirements of Section 8.11. If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to such series of Securities shall be
appointed by the 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 with respect to such series, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
with respect to such series and to that extent supersede the successor Trustee
appointed by the Company with respect to such series. If no successor Trustee
with respect to such series shall have been so appointed by the Company or the
Holders of Securities of such series and accepted appointment in the manner
hereinafter provided, any Holder 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 such series.

(vi) 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 by mailing
written notice of such event by first- class mail, postage prepaid, to the
Holders of Registered Securities of such series as their names and addresses
appear in the Security Register and, if Securities of such series are issuable
as Bearer Securities, by publishing notice of such event once in an Authorized
Newspaper in each Place of Payment located outside the United States. Each
notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Principal Corporate Trust
Office.

SECTION 8.11. Acceptance of Appointment by Successor. (i) In the case of the
appointment hereunder of a successor Trustee with respect to any series of
Securities, every such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective with respect to all or any series as to which it
is resigning as Trustee, and such successor Trustee, without any

                                       43
<PAGE>

further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee with respect to all or any
such series; but, on request of the Company or such 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 such retiring Trustee with respect to all or any such series; and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to all or any
such series.

(ii) 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 wherein each
successor Trustee shall accept such appointment and which (a) 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, (b) 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 (c) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be Trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates, subject
nevertheless to its lien, if any, provided for in Section 8.07.

(iii) 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 (i) or (ii) of this Section, as the case may be.

(iv) No successor Trustee with respect to a series of Securities shall accept
its appointment unless at the time of such acceptance such successor Trustee
shall be qualified and eligible with respect to such series under this Article.

SECTION 8.12. Merger, Conversion, Consolidation or Succession to Business of
Trustee. 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 that 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 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 so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

SECTION 8.13. Preferential Collection of Claims against Company. If and when the
Trustee shall be or become a creditor of the Company (or any other obligor upon
the Securities), the Trustee shall be subject to the provisions of Section 311
of the Trust Indenture Act regarding the collection of such claims against the
Company (or any such other obligor). A Trustee that has resigned or been removed
shall be subject to and comply with said Section 311 to the extent required
thereby.

SECTION 8.14. Appointment of Authenticating Agents. The Trustee may appoint an
Authenticating Agent or Agents, which may include any Affiliate of the Company,
with respect to one or more series of Securities. Such Authenticating Agent or
Agents at the option of the Trustee shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon original issuance,
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 3.06, 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. Whenever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication or the delivery of Securities to the
Trustee for authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent,
a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent and delivery of Securities to the Authenticating Agent on
behalf of the Trustee. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authen-ticating
Agent, having a combined capital and surplus of not less than $5,000,000 and
subject to supervision or examination by Federal or State authority.
Notwithstanding the foregoing, an Authenticating Agent located outside the
United States may be appointed by the Trustee if previously approved in writing
by the Company and if such Authenticating Agent meets the minimum capitalization
requirements of this Section 8.14. If such Authenticating Agent publishes
reports of condition at least annually, pursuant to law or to the requirements
of said supervising or examining authority, then for the purposes of this
Section, the combined capital

                                       44
<PAGE>

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. If 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 any further act on the part of
the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof
to the Trustee and to the Company. The Trustee may at any time (and upon request
by the Company shall) terminate the agency of an Authenticating Agent by giving
written notice thereof to such Authenticating Agent and to the Company. Upon
receiving such a notice of resignation or upon such 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 may appoint a successor
Authenticating Agent which shall be acceptable to the Company. 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. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
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
the Trustee's certificate of authentication, an alternate certificate of
authentication in the following form:

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

                             SUPPLEMENTAL INDENTURES

SECTION 9.01. Supplemental Indentures Without Consent of Holders. Without the
consent of any Holder of any Securities or coupons, the Company, when authorized
by 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:

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

(ii) to evidence and provide for the acceptance of appointment by another
corporation as a successor Trustee hereunder with respect to one or more series
of Securities 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, pursuant to Section 8.11; or

(iii) to add to the covenants of the Company, for the benefit of the Holders of
Securities of all or any series of Securities or coupons (and if such covenants
are to be for the benefit of less than all series of Securities or coupons,
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

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

SECTION 9.02. Supplemental Indentures With Consent of Holders. With the consent
of the Holders of not less than a majority in aggregate principal amount of the

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.

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.

SECTION 9.03. Execution of Supplemental Indentures. In executing, or accepting
the additional trusts created by, any supplemental indenture permitted by this
Article or the modifications thereby of the trusts created by this Indenture,

complies with this Indenture. The Trustee may, but shall not be obligated to,
enter into any such supplemental indenture which affects the Trustee's own
rights, liabilities, duties or immunities under this Indenture or otherwise.

such supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding
Securities.

SECTION 9.07. Subordination Unimpaired. No supplemental indenture executed
pursuant to this Article shall directly or indirectly modify the provisions of

merged or to which such conveyance or transfer is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Company under

covenants under this Indenture and may be dissolved, wound up and liquidated at
any time thereafter.

cease to be of further effect (except as to any surviving rights of registration
of transfer or exchange of Securities herein expressly provided for and rights
to receive payments thereon and any right to receive additional amounts, as
provided in Section 5.04), and the Trustee, on receipt of a Company Request and
at the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

caused to be deposited with the Trustee, as trust funds in trust for the

Redemption Date, as the case may be;

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

(iii) the Company has delivered to the Trustee an Officers' Certificate and an
Opinion of Counsel each stating that all conditions precedent herein provided

have been deposited with the Trustee pursuant to subclause (b) of clause (i) of
this Section, the obligations of the Trustee under Section 11.02 and the last
paragraph of Section 5.03 shall survive. The Trustee may give notice at the
Company's expense to the Holders of Securities Outstanding of the immediate
availability of the amount referred to in clause (i) of this Section 11.01.
Funds held pursuant to this Section shall not be subject to the provisions of
Article Fourteen.

SECTION 11.02. Application of Trust Money. Subject to the provisions of the last
paragraph of Section 5.03, all money deposited with the Trustee pursuant to
Section 11.01 shall be held in trust and applied by it, in accordance with the

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

SECTION 11.03. Reinstatement. If the Trustee or any Paying Agent is unable to
apply any money in accordance with Section 11.02 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental

Company's obligations under this Indenture and the Securities shall be revived
and reinstated as though no deposit had occurred pursuant to Section 11.01 until
such time as the Trustee or any Paying Agent is permitted to apply all such
money in accordance with Section 11.02.

                             OFFICERS AND DIRECTORS

SECTION 12.01. Exemption from Individual Liability. No recourse under or upon
any obligation, covenant or agreement of this Indenture, or of any Security or
coupon, or for any claim based thereon or otherwise in respect thereof, shall be
had against any incorporator, stockholder, officer or director, as such, past,
present or future, of the Company or of any successor corporation, either
directly or through the Company, whether by virtue of any constitution, statute

contained in this Indenture or in any of the Securities or coupons or implied

                                ARTICLE THIRTEEN

                                  SINKING FUNDS

SECTION 13.01. 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 3.01 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 Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 13.02. 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 13.02. Satisfaction of Sinking Fund Payments with Securities. The
Company (i) may deliver Outstanding Securities of a 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 (ii) may
apply as a credit Securities of a series which have been redeemed either at the
election of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any sinking
fund payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

SECTION 13.03. Redemption of Securities for Sinking Fund. Not less than 60 days
prior to each sinking fund payment date for any series of Securities, the
Company will deliver to the Trustee and the Security Registrar an Officers'
Certificate specifying (i) the amount of the next ensuing sinking fund payment
for that series pursuant to the terms of that series, (ii) the portion thereof,
if any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities of that
series pursuant to Section 13.02, and (iii) that none of such Securities has
theretofore been so credited and stating the basis for such credit, and will
also deliver to the Trustee any Securities to be so delivered. Not less than 30
days before each sinking fund payment date the Security Registrar shall select
the Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 4.03 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 4.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
4.06 and 4.07.

                                ARTICLE FOURTEEN

                           SUBORDINATION OF SECURITIES

SECTION 14.01. Agreement To Subordinate. The Company, for itself, its successors
and assigns, covenants and agrees, and each Holder of a Security by his
acceptance thereof, likewise covenants and agrees, that the payment of the
principal and premium, if any, and interest on each and all of the Securities is
hereby expressly subordinated, to the extent and in the manner hereinafter set
forth, in right of payment to the prior payment in full of all Senior
Indebtedness and, subject to the provisions of Section 14.09, General
Obligations of the Company.

SECTION 14.02. Distribution on Dissolution, Liquidation and Reorganization;
Subrogation of Securities. Upon any distribution of assets of the Company upon
any dissolution, winding up, liquidation or reorganization of the Company,
whether in bankruptcy, insolvency, reorganization or receivership proceedings or
upon an assignment for the benefit of creditors or any other marshalling of the
assets and liabilities of the Company or otherwise (subject to the power of a
court of competent jurisdiction to make other equitable provision reflecting the
rights conferred in this Indenture upon the Senior Indebtedness and the holders
thereof with respect to the Securities and the Holders thereof (and, upon the
General Obligations and the creditors in respect thereof with respect to the
Securities and the Holders thereof) by a lawful plan of reorganization under
applicable bankruptcy law);

(i) the holders of all Senior Indebtedness shall first be entitled to receive
payment in full in accordance with the terms of such Senior Indebtedness of the
principal thereof, premium, if any, and the interest due thereon (including
interest accruing subsequent to the commencement of any proceeding for the
bankruptcy or reorganization of the Company under any applicable bankruptcy,
insolvency, or similar law now or hereafter in effect) before the Holders of the
Securities are entitled to receive any payment upon the principal of or premium,
if any, or interest on indebtedness evidenced by the Securities;

(ii) any payment or distribution of assets of the Company 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 Fourteen, including any such payment or distribution which may be
payable or deliverable by reason of the payment of any other indebtedness of the
Company being subordinated to the payment of the Securities, shall be paid by
the liquidating trustee or agent or other person making such

                                       49
<PAGE>

payment or distribution, whether a trustee in bankruptcy, a receiver or
liquidating trustee or otherwise, directly to the holders of Senior Indebtedness
or their representative or representatives or to the trustee or trustees under
any indenture under which any instruments evidencing any of such Senior
Indebtedness may have been issued, in accordance with the priorities then
existing among holders of Senior Indebtedness for payment of the aggregate
amounts remaining unpaid on account of the principal of and premium, if any, and
interest (including interest accruing subsequent to the commencement of any
proceeding for the bankruptcy or reorganization of the Company under any
applicable bankruptcy, insolvency or similar law now or hereafter in effect) on
the Senior Indebtedness held or represented by each, to the extent necessary to
make payment in full of all Senior Indebtedness remaining unpaid, after giving
effect to any concurrent payment or distribution to the holders of such Senior
Indebtedness; it being understood that if the Holders of Securities shall fail
to file a proper claim in the form required by any proceeding referred to in
this subparagraph (ii) prior to 30 days before the expiration of the time to
file such claim or claims, then the holders of Senior Indebtedness are hereby
authorized to file an appropriate claim or claims for and on behalf of the
Holders of Securities in the form required in any such proceeding (as are the
creditors in respect of General Obligations in the event Section 14.09 is
applicable); and

(iii) in the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, including any such payment or distribution which may be
payable or deliverable by reason of the payment of any other indebtedness of the
Company being subordinate to the payment of the Securities, shall be received by
the Trustee or Holders of the Securities before all Senior Indebtedness is paid
in full, such payment or distribution shall be held in trust for the benefit of
and shall be paid over to the holders of such Senior Indebtedness or their
representative or representatives or to the trustee or trustees under any
indenture under which any instruments evidencing any of such Senior Indebtedness
may have been issued, ratably as aforesaid, for application to the payment of
all Senior Indebtedness remaining unpaid until all such Senior Indebtedness
shall have been paid in full, after giving effect to any concurrent payment or
distribution to the holders of such Senior Indebtedness.

Subject to the payment in full of all Senior Indebtedness, the Holders of the
Securities shall be subrogated (equally and ratably with the holders of all
indebtedness of the Company which by its express terms is subordinated to
indebtedness of the Company to substantially the same extent as the Securities
are subordinated and is entitled to like rights of subrogation) to the rights of
the holders of Senior Indebtedness to receive payments or distributions of cash,
property or securities of the Company applicable to the Senior Indebtedness
until the principal of and premium, if any, and interest on the Securities shall
be paid in full and no such payments or distributions to holders of such Senior
Indebtedness to which the Holders of the Securities would be entitled except for
the provisions hereof of cash, property or securities otherwise distributable to
the Senior Indebtedness shall, as between the Company, its creditors, other than
the holders of Senior Indebtedness and the Holders of the Securities, be deemed
to be a payment by the Company to or on account of the Securities. It is
understood that the provisions of this Article Fourteen 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 (and, in the
case of Section 14.09, the Holders of the Securities, on the one hand, and
creditors in respect of General Obligations) on the other hand. Nothing
contained in this Article Fourteen or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as between the Company, its
creditors, other than the holders of Senior Indebtedness, and the Holders of the
Securities, the obligation of the Company, which is unconditional and absolute
(and which, subject to the rights under this Article Fourteen of the holders of
the Senior Indebtedness and the rights under Section 14.09 of creditors in
respect of General Obligations, is intended to rank equally with all other
general obligations of the Company), to pay to the Holders of the Securities the
principal of, premium, if any, and interest on the Securities as and when the
same shall become due and payable in accordance with their terms or to affect
the relative rights of the Holders of the Securities and creditors of the
Company, other than the holders of the Senior Indebtedness and creditors in
respect of General Obligations, nor shall anything herein or in the Securities
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 Fourteen of the holders of Senior
Indebtedness and under Section 14.09 of creditors in respect of General
Obligations in respect of cash, property or securities of the Company received
upon the exercise of any such remedy. Upon any payment or distribution of assets
of the Company referred to in this Article Fourteen, the Trustee, subject to the
provisions of Section 8.01, and the Holders of the Securities shall be entitled
to rely upon any order or decree of a court of competent jurisdiction in which
such dissolution, winding up, liquidation or reorganization proceedings are
pending or upon a certificate of the liquidating trustee or agent or other
person making any distribution 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 the Senior Indebtedness and other
indebtedness of the Company and the creditors in respect of General Obligations,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article Fourteen. In
the absence of any such liquidating trustee, agent or other person, the Trustee
shall be entitled to rely upon a written notice by a Person representing himself
to be a holder of Senior Indebtedness (or a trustee or representative on behalf
of such holder) or a creditor in respect of General Obligations as evidence that
such Person is a holder of Senior Indebtedness (or is such a trustee or
representative) or a creditor in respect of General Obligations, as the case may
be. 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 or a creditor in respect of General Obligations, to
participate in any payment or distribution pursuant to this Section or Section
14.09, the Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness or General
Obligations held by such Person, as to the extent to which such Person is
entitled to participation in such payment or distribution, and as to other facts
pertinent to the rights of such Person under this Section or Section 14.09, and
if such evidence is not

                                       50
<PAGE>

furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

The obligations of the Company in respect of the Securities shall rank on a
parity with the Existing Subordinated Indebtedness and any other obligations of
the Company ranking on a parity with the Securities.

With respect to the holders of Senior Indebtedness or creditors in respect of
General Obligations, the Trustee undertakes to perform or to observe only such
of its covenants and obligations as are specifically set forth in this Article,
and no implied covenants or obligations with respect to the holders of Senior
Indebtedness or creditors in respect of General Obligations shall be read into
this Indenture against the Trustee. The Trustee, however, shall not be deemed to
owe any fiduciary duty to the holders of Senior Indebtedness or creditors in
respect of General Obligations, and shall not be liable to any such holders or
creditors if it shall mistakenly pay over or distribute to or on behalf of
Holders of Securities or the Company moneys or assets to which any holders of
Senior Indebtedness or creditors in respect of General Obligations shall be
entitled by virtue of this Article Fourteen.

SECTION 14.03. Payments on Securities Prohibited During Event of Default under
Senior Indebtedness. In the event and during the continuation of any default in
the payment of principal of, or premium, if any, or interest on, any Senior
Indebtedness beyond any applicable period of grace, or in the event that any
event of default with respect to any Senior Indebtedness shall have occurred and
be continuing, or would occur as a result of the payment referred to
hereinafter, permitting the holders of such Senior Indebtedness (or a trustee on
behalf of the holders thereof) to accelerate the maturity thereof, then, unless
and until such default or event of default shall have been cured or waived or
shall have ceased to exist, no payment of principal of, or premium or interest
on the Securities, or in respect of any redemption, retirement, purchase or
other acquisition of any of the Securities, shall be made by the Company.

SECTION 14.04. Payments on Securities Permitted. Nothing contained in this
Indenture or in any of the Securities shall (i) impair, as between the Company
and Holders of Securities, the obligation of the Company to make, or prevent the
Company from making, at any time except as provided in Sections 14.02, 14.03,
14.08 and 14.09, payments of principal of or premium, if any, or interest
(including interest accruing subsequent to the commencement of any proceeding
for the bankruptcy or reorganization of the Company under any applicable
bankruptcy, insolvency or similar law now or hereafter in effect) on the
Securities, as and when the same shall become due and payable in accordance with
the terms of the Securities, (ii) affect the relative rights of the Holders of
the Securities and creditors of the Company other than the holders of the Senior
Indebtedness of the Company and the creditors in respect of General Obligations,
(iii) prevent the Trustee or the Holder of any Security from exercising all
remedies otherwise permitted by applicable law upon default thereunder, subject
to the rights, if any, under Article Fourteen of the holders of Senior
Indebtedness and the creditors in respect of General Obligations in respect of
cash, property or securities of the Company received upon the exercise of such
remedy, or (iv) prevent the application by the Trustee or any Paying Agent of
any moneys deposited with it hereunder to the payment of or on account of the
principal of or premium, if any, or interest on the Securities or prevent the
receipt by the Trustee or any Paying Agent of such moneys, if, prior to the
second Business Day prior to such deposit, the Trustee or such Paying Agent did
not have written notice of any event prohibiting the making of such deposit by
the Company.

SECTION 14.05. Authorization of Holders to Trustee To Effect Subordination. Each
Holder of a Security by his acceptance thereof authorizes and directs the
Trustee in his behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article Fourteen and appoints
the Trustee his attorney-in-fact for any and all such purposes.

SECTION 14.06. Notice to Trustee. Notwithstanding the provisions of this Article
or any other provisions of this Indenture, neither the Trustee nor any Paying
Agent shall be charged with knowledge of the existence of any Senior
Indebtedness or General Obligations or of any event which would prohibit the
making of any payment of moneys to or by the Trustee or such Paying Agent,
unless and until the Trustee or such Paying Agent shall have received written
notice thereof from the Company or from the holder of any Senior Indebtedness or
from the representative of any such holder or from any creditor in respect of
General Obligations.

SECTION 14.07. Right of Trustee To Hold Senior Indebtedness or General
Obligations. The Trustee shall be entitled to all of the rights set forth in
this Article in respect of any Senior Indebtedness or General Obligation at any
time held by it in its individual capacity to the same extent as any other
holder of such Senior Indebtedness or creditor in respect of such General
Obligation and nothing in this Indenture shall be construed to deprive the
Trustee of any of its rights as such holder or creditor.

SECTION 14.08. Article Fourteen Not To Prevent Defaults or Events of Default.
The failure to make a payment pursuant to the Securities by reason of any
provision in this Article shall not be construed as preventing the occurrence of
a Default or an Event of Default.

SECTION 14.09. Securities To Rank Pari Passu with Existing SUBORDINATED
INDEBTEDNESS; PAYMENT OF PROCEEDS IN CERTAIN CASES. (i) SUBJECT TO the
provisions of this Section and to any provisions established or determined with
respect to Securities of any series pursuant to Section 3.01, the Securities
shall rank pari passu in right of payment with the Existing Subordinated
Indebtedness.

(ii) Upon the occurrence of any of the events specified in the first paragraph
of Section 14.02, the provisions of that Section and the corresponding
provisions of each indenture or other instrument or document establishing or
governing the terms of any Existing

                                       51
<PAGE>

Subordinated Indebtedness shall be given effect on a pro rata basis to determine
the amount of cash, property or securities which may be payable or deliverable
as between the holders of Senior Indebtedness, on the one hand, and the Holders
of the Securities and holders of Existing Subordinated Indebtedness, on the
other hand.

(iii) If, after giving effect to the provisions of Section 14.02, and the
respective corresponding provisions of each indenture or other instrument or
document establishing or governing the terms of any Existing Subordinated
Indebtedness on such pro rata basis, any amount of cash, property or securities
shall be available for payment or distribution in respect of the Securities
("Excess Proceeds"), and any creditors in respect of General Obligations shall
not have received payment in full of all amounts due or to become due on or in
respect of such General Obligations (and provision shall not have been made for
such payment in money or money's worth), then such Excess Proceeds shall first
be applied (ratably with any amount of cash, property or securities available
for payment or distribution in respect of any other indebtedness of the Company
that by its express terms provides for the payment over of amounts corresponding
to Excess Proceeds to creditors in respect of General Obligations) to pay or
provide for the payment of the General Obligations remaining unpaid, to the
extent necessary to pay all General Obligations in full, after giving effect to
any concurrent payment or distribution to or for creditors in respect of General
Obligations. Any Excess Proceeds remaining after payment (or provision for
payment) in full of all General Obligations shall be available for payment or
distribution in respect of the Securities.

(iv) In the event that, notwithstanding the foregoing provisions of subsection
(iii) of this Section, the Trustee or Holder of any Security shall, in the
circumstances contemplated by such subsection, have received any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, before all General Obligations are paid in full or
payment thereof duly provided for, and if such fact shall, at or prior to the
time of such payment or distribution have been made known to the Trustee or, as
the case may be, such Holder, then and in such event, subject to any obligation
that the Trustee or such Holder may have pursuant to Section 14.02, such payment
or distribution shall be paid over or delivered forthwith to the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other
Person making payment or distribution of assets of the Company for payment in
accordance with subsection (iii).

(v) Subject to the payment in full of all General Obligations, the Holder of the
Securities shall be subrogated (equally and ratably with the holders of all
indebtedness of the Company that by its express terms provides for the payment
over of amounts corresponding to Excess Proceeds to creditors in respect of
General Obligations and is entitled to like rights of subrogation) to the rights
of the creditors in respect of General Obligations to receive payments or
distributions of cash, property or securities applicable to the General
Obligations until the principal of and interest on the Securities shall be paid
in full. For purposes of such subrogation, no payments or distributions to
creditors in respect of General Obligations of any cash, property or securities
to which Holders of the Securities or the Trustee would be entitled except for
the provisions of this Section, and no payments over pursuant to the provisions
of this Section to creditors in respect of General Obligations by Holders of
Securities or the Trustee, shall, as among the Company, its creditors (other
than creditors in respect of General Obligations) and the Holders of Securities
be deemed to be a payment or distribution by the Company to or on account of the
Securities.

(vi) The provisions of subsections (iii), (iv) and (v) of this Section 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 creditors in respect of
General Obligations, on the other hand, after giving effect to the rights of the
holders of Senior Indebtedness, as provided in this Article. Nothing contained
in subsections (iii), (iv) and (v) of this Section is intended to or shall
affect the relative rights against the Company of the Holders of the Securities
and (a) the holders of Senior Indebtedness (b) the holders of Existing
Subordinated Indebtedness or (c) other creditors of the Company other than
creditors in respect of General Obligations.

                                 ARTICLE FIFTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

SECTION 15.01. Applicability of Article. Securities of any series which are
repayable at the option of the Holders thereof before their Stated Maturity
shall be repaid in accordance with their terms and (except as otherwise
specified pursuant to Section 3.01 for Securities of such series) in accordance
with this Article.

SECTION 15.02. Repayment of Securities. Each Security which is subject to
repayment in whole or in part at the option of the Holder thereof on a Repayment
Date shall be repaid at the applicable Repayment Price together with interest
accrued to such Repayment Date as specified pursuant to Section 3.01.

SECTION 15.03. Exercise of Option; Notice. Each Holder desiring to exercise such
Holder's option for repayment shall, as conditions to such repayment, surrender
the Security to be repaid in whole or in part together with written notice of
the exercise of such option at any office or agency of the Company in a Place of
Payment, not less than 30 nor more than 45 days prior to the Repayment Date;
provided, however, that surrender of Bearer Securities together with written
notice of exercise of such option shall be made at an office or agency located
outside the United States except as otherwise provided in Section 5.02. Such
notice, which shall be irrevocable, shall specify the principal amount of such
Security to be repaid, which shall be equal to the minimum authorized

                                       52
<PAGE>

denomination for such Security or an integral multiple thereof, and shall
identify the Security to be repaid and, in the case of a partial repayment of
the Security, shall specify the denomination or denominations of the Security or
Securities of the same series to be issued to the Holder for the portion of the
principal of the Security surrendered which is not to be repaid.

If any Bearer Security surrendered for repayment shall not be accompanied by all
unmatured coupons and all matured coupons in default, such Bearer Security may
be paid after deducting from the Repayment 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 Bearer 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 Repayment Price, such Holder
shall be entitled to receive the amount so deducted without interest thereon;
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 5.02.

The Company shall execute and the Trustee shall authenticate and deliver without
service charge to the Holder of any Registered Security so surrendered a new
Registered Security or Securities of the same series and tender of any
authorized denomination specified in the foregoing notice, in an aggregate
principal amount equal to any portion of the principal of the Registered
Security so surrendered which is not to be repaid.

The Company shall execute and the Trustee shall authenticate and deliver without
service charge to the Holder of any Bearer Security so surrendered a new
Registered Security or Securities or new Bearer Security or Securities (and all
appurtenant unmatured coupons and matured coupons in default) or any combination
thereof of the same series and tenor of any authorized denomination or
denominations specified in the foregoing notice, in an aggregate principal
amount equal to any portion of the principal of the Security so surrendered
which is not to be repaid; provided, however, that the issuance of a Registered
Security therefor shall be subject to applicable laws and regulations, including
provisions of the United States federal income tax laws and regulations in
effect at the time of the exchange; neither the Company, the Trustee nor the
Security Registrar shall issue Registered Securities for Bearer Securities if it
has received an Opinion of Counsel that as a result of such issuance the Company
would suffer adverse consequences under the United States federal income tax
laws then in effect and the Company has delivered to the Trustee a Company Order
directing the Trustee not to make such issuances thereafter unless and until the
Trustee receives a subsequent Company Order to the contrary. The Company shall
deliver copies of such Company Order to the Security Registrar.

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

SECTION 15.04. Election of Repayment by Remarketing Entities. The Company may
elect, with respect to Securities of any series which are repayable at the
option of the Holders thereof before their Stated Maturity, at any time prior to
any Repayment Date to designate one or more Remarketing Entities to purchase, at
a price equal to the Repayment Price, Securities of such series from the Holders
thereof who give notice and surrender their Debt Securities in accordance with
Section 15.03.

SECTION 15.05. Securities Payable on the Repayment Date. Notice of exercise of
the option of repayment having been given and the Securities so to be repaid
having been surrendered as aforesaid, such Securities shall, unless purchased in
accordance with Section 15.04, on the Repayment Date become due and payable at
the price therein specified and from and after the Repayment Date such
Securities shall cease to bear interest and shall be paid on the Repayment Date,
and the coupons for such interest appertaining to Bearer Securities so to be
repaid, except to the extent provided above, shall be void, unless the Company
shall default in the payment of such price, in which case the Company shall
continue to be obligated for the principal amount of such Securities and shall
be obligated to pay interest on such principal amount at the rate prescribed
therefor by such Securities from time to time until payment in full of such
principal amount.

                                 ARTICLE SIXTEEN

                        MEETINGS OF HOLDERS OF SECURITIES

(ii) In case at any time the Company, pursuant to a Board Resolution, or the
Holders of at least 10% in principal amount of the Outstanding Securities of any
series shall have requested the Trustee to call a meeting of the Holders of
Securities of such series for any purpose specified in Section 16.01, by written
request setting forth in reasonable detail the action proposed to be taken at
the meeting, and the Trustee shall not have made the first publication of the
notice of such meeting within 21 days after receipt of such request or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place in the City
of Columbus, Ohio, the Borough of Manhattan, The City of New York, or in London
for such meeting and may call such meeting for such purposes by giving notice

such meeting and their counsel, any representatives of the Trustee and its
counsel and any representatives of the Company and its counsel.

SECTION 16.04. Quorum, Action. The Persons entitled to vote a majority in
principal amount of the Outstanding Securities of a series shall constitute a

that if any action is to be taken at such meeting with respect to a consent or
waiver which this Indenture expressly provides may be given by the Holders of a
greater percentage in principal amount of the Outstanding Securities of a
series, the Persons entitled to vote such greater percentage in principal amount
of the Outstanding Securities of such series shall constitute a quorum. In the
absence of a quorum within 30 minutes of the time appointed for any such
meeting, the meeting shall, if convened at the request of Holders of Securities
of such series, be dissolved. In the absence of a quorum in any other case the
meeting may be adjourned for a period of not less than 10 days as determined by
the chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at any such adjourned meeting, such adjourned meeting may be

Notice of the reconvening of any adjourned meeting shall be given as provided in

five days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of an 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. Except as limited by
the provisos to Section 9.02, any resolution presented to a meeting or adjourned

only by the affirmative vote of the Holders of a majority in principal amount of
the Outstanding Securities of the series; provided, however, that, except as
limited by the provisos to Section 9.02, any resolution with respect to any
consent or waiver which this Indenture expressly provides may be given by the
Holders of a greater percentage 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 only by the affirmative
vote of the Holders of such greater percentage in principal amount of the
Outstanding Securities of that series; and provided further that, except as
limited by the provisos to Section 9.02, any resolution with respect to any
request, demand, authorization, direction, notice, consent, waiver or other Act
which this Indenture expressly provides may be made, given or taken by the
Holders of a specified percentage, which is less than a majority in principal
amount of the Outstanding Securities of a series may be adopted at a meeting or
an adjourned meeting duly reconvened and at which a quorum is present as
aforesaid by the affirmative vote of the Holders of such specified percentage in
principal amount of the Outstanding Securities of that series.

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

SECTION 16.05. Determination of Voting Rights; Conduct and Adjournment of
Meetings. (a) Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of such 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
1.04 and the appointment of any proxy shall be proved in the manner specified in
Section 1.04 or, in the case of Bearer Securities, by having the signature of
the person executing the proxy witnessed or guaranteed by any trust company,
bank or banker authorized by Section 1.04 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 1.04 or other proof.

(b) The Trustee shall, by an instrument in writing, appoint a temporary
chairperson of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 16.02(ii), 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 chairperson. A
permanent

                                       54
<PAGE>

chairperson 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 (or the equivalent in ECU,
any other composite currency or a Foreign Currency) of 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 chairperson of the meeting not to be Outstanding. The
chairperson 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 16.02 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 16.06. Counting Votes and Recording Action of Meetings. The vote upon
any resolution submitted to any meeting of Holders of Securities of any series
shall be by written ballots on which shall be subscribed the signatures of the
Holders of Securities of such series or of their representatives by proxy and
the principal amounts and serial numbers of the Outstanding Securities of such
series held or represented by them. The permanent chairperson 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 triplicate of all
votes cast at the meeting. A record, at least in triplicate, 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 facts setting forth a
copy of the notice of the meeting and showing that said notice was given as
provided in Section 16.02 and, if applicable, Section 16.04. Each copy shall be
signed and verified by the affidavits of the permanent chairperson 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.
