          If any Debt Security of a series is issuable in global form (a "Global

          Section 3.02.  Denominations.
                         -------------

          In the absence of any specification pursuant to Section 3.01 with

          Section 3.03.  Execution, Authentication, Delivery and Dating.
                         ----------------------------------------------

          The Debt Securities of any series shall be executed on behalf of the
Company by its Chairman of the Board, its Chief Executive Officer, its
President, one of its Vice Presidents or its Treasurer, attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers may be manual or facsimile. Coupons shall bear the facsimile signature
of the Treasurer or any Assistant Treasurer of the Company.

          Debt 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
Debt Securities and Coupons or did not hold such offices at the date of such
Debt Securities and Coupons.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debt Securities, with appropriate
Coupons, if any, of any series, executed by the Company, to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Debt Securities and Coupons and the Trustee in accordance with
the Company Order shall authenticate and deliver such Debt Securities and
Coupons; provided, however, that, in connection with its sale during the
         --------  -------
"restricted period" (as defined in Section 1.163-5(c)(2)(i)(D)(7) of the United
States Treasury Regulations), no Bearer Security shall be mailed or otherwise
delivered to any location in the United States; and provided, further, that a
                                                    --------  -------
Bearer Security (other than a temporary Global Note in bearer form) may be
delivered outside the United States in connection with its original issuance
only if the Person entitled to receive such Bearer Security shall have furnished
to the Euro-clear Operator or to CEDEL a certificate substantially in the form
set forth in Exhibit A to this Indenture. If all the Debt Securities of any one
series are not to be issued at one time and if a Board Resolution or
supplemental indenture relating to such series shall so permit, such Company
Order may set forth procedures acceptable to the Trustee for the issuance of
such Debt Securities such as interest rate, Stated Maturity, date of issuance
and date from which interest, if any, shall accrue. If
<PAGE>

                                                                              28

any Debt Security shall be represented by a permanent Global Note, then, for
purposes of this Section and Section 3.04, the notation of a beneficial owner's
interest therein upon original issuance of such Debt Security or upon exchange
of a portion of a temporary Global Note shall be deemed to be delivery in
connection with the original issuance of such beneficial owner's interest in
such permanent Global Note. Except as permitted by Section 3.06 or 3.07, the
Trustee shall not authenticate and deliver any Bearer Security unless all
Coupons for interest then matured have been detached and cancelled.

          The Trustee shall be entitled to receive, and (subject to Section
6.01) shall be fully protected in relying upon, prior to the authentication and
delivery of the Debt Securities and Coupons of such series, (i) the supplemental
indenture or the Board Resolution by or pursuant to which the form and terms of
such Debt Securities and Coupons have been approved and (ii) an Opinion of
Counsel substantially to the effect that:

          (1) all instruments furnished by the Company to the Trustee in
     connection with the authentication and delivery of such Debt Securities and
     Coupons conform to the requirements of this Indenture and constitute
     sufficient authority hereunder for the Trustee to authenticate and deliver
     such Debt Securities and Coupons;

          (2) the forms and terms of such Debt Securities and Coupons have been
     established in conformity with the provisions of this Indenture;

          (3) in the event that the forms or terms of such Debt Securities and
     Coupons have been established in a supplemental indenture, the execution
     and delivery of such supplemental indenture has been duly authorized by all
     necessary corporate action of the Company, such supplemental indenture has
     been duly executed and delivered by the Company and, assuming due
     authorization, execution and delivery by the Trustee, is a valid and
     binding obligation enforceable against the Company in accordance with its
     terms, subject to applicable bankruptcy, insolvency and similar laws
     affecting creditors' rights generally and subject, as to enforceability, to
     general principles of equity (regardless of whether enforcement is sought
     in a proceeding in equity or at law); and

          (4) the execution and delivery of such Debt Securities and Coupons
     have been duly authorized by all necessary corporate action of the Company
     and such Debt Securities and Coupons have been duly executed by the Company
     and, assuming due authentication by the Trustee and delivery by the
     Company, are valid and binding obligations enforceable against the Company
     in accordance with their terms, entitled
<PAGE>

                                                                              29

     to the benefit of the Indenture, subject to applicable bankruptcy,
     insolvency and similar laws affecting creditors' rights generally and
     subject, as to enforceability, to general principles of equity (regardless
     of whether enforcement is sought in a proceeding in equity or at law) and
     subject to such other exceptions as counsel shall request and as to which
     the Trustee shall not reasonably object.

          The Trustee shall not be required to authenticate such Debt Securities
and Coupons if the issuance of such Debt Securities and Coupons pursuant to this
Indenture will affect the Trustee's own rights, duties or immunities under the
Debt Securities and this Indenture in a manner which is not reasonably
acceptable to the Trustee.

          Each Registered Security shall be dated the date of its
authentication. Each Bearer Security (including any temporary or permanent or
other definitive Bearer Security in global form) shall be dated as of the date
of original issuance of the first Debt Security of such series to be issued,
except as otherwise provided pursuant to Section 3.01 with respect to the Bearer
Securities of any series.

          No Debt Security or Coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Debt Security a certificate of authentication substantially in one of the forms
provided for herein duly executed by the Trustee or by an Authenticating Agent,
and such certificate upon any Debt Security shall be conclusive evidence, and
the only evidence, that such Debt Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Debt Security shall have been duly
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Debt Security to the Trustee for cancellation
as provided in Section 3.08 together with a written statement (which need not
comply with Section 1.02) stating that such Debt Security has never been issued
and sold by the Company, for all purposes of this Indenture such Debt Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

Notes for Definitive Bearer Securities; Global Notes Representing Registered
----------------------------------------------------------------------------
Securities.
----------

          (a) Pending the preparation of definitive Registered Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Registered Securities which are printed,
lithographed,
<PAGE>

                                                                              30

typewritten, mimeographed or otherwise produced, in any authorized denomination
for Registered Securities of such series, substantially of the tenor of the
definitive Registered Securities in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Registered Securities may determine, as conclusively
evidenced by their execution of such Registered Securities. Every such temporary
Registered Security shall be executed by the Company and shall be authenticated
and delivered by the Trustee upon the same conditions and in substantially the
same manner, and with the same effect, as the definitive Registered Securities
in lieu of which they are issued. In the case of any series issuable as Bearer
Securities, such temporary Debt Securities may be in global form, and with one
or more Coupons or without Coupons, representing such of the Outstanding Debt
Securities of such series as shall be specified therein.

          Except in the case of temporary Debt Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), if temporary Debt Securities of any series are issued, the Company
will cause definitive Debt Securities of such series to be prepared without
unreasonable delay. After the preparation of definitive Debt Securities of such
series, the temporary Debt Securities of such series shall be exchangeable for
definitive Debt Securities of such series, of a like Stated Maturity and with
like terms and provisions, upon surrender of the temporary Debt Securities of
such series at the office or agency of the Company in a Place of Payment for
such series, without charge to the Holder, except as provided in Section 3.05 in
connection with a transfer. Upon surrender for cancellation of any one or more
temporary Debt Securities of any series (accompanied by any unmatured Coupons),
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Debt Securities of the
same series of authorized denominations and of a like Stated Maturity and like
terms and provisions; 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 (including a permanent
--------  -------
Bearer Security in global form) 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 Registered Securities of any series
shall in all respects be entitled to the same benefits under this Indenture as
definitive Registered Securities of such series.

          (b) Unless otherwise specified pursuant to Section 3.01, all Bearer
Securities of a series shall be initially issued in the form of a single
temporary Bearer Security in global form (a "temporary Global Note"). The
Company shall execute, and upon
<PAGE>

                                                                              31

Company Order the Trustee shall authenticate, any temporary Global Note and any
permanent Bearer Security in global form (as described below, a "permanent
Global Note") upon the same conditions and in substantially the same manner, and
with the same effect, as definitive Bearer Securities, and the temporary or
permanent Global Note, as the case may be, shall, unless otherwise specified
therein, be delivered by the Trustee to the London office of a depositary or
common depositary (the "Common Depositary"), for the benefit of the Euro-clear
Operator or CEDEL, as the case may be, for credit to the account of the Company
(in the case of sales of Bearer Securities by the Company directly to investors)
or the managing underwriter (in the case of sales of Bearer Securities by the
Company to underwriters) or such other accounts as the Company or the managing
underwriter, respectively, may direct.

          On or after the date specified in or determined pursuant to the terms
of any temporary Global Note which (subject to any applicable laws and
regulations) shall be at least 40 days after the issue date of a temporary
Global Note (the "Exchange Date"), the Debt Securities represented by such
temporary Global Note may be exchanged for definitive Debt Securities (subject
to the second succeeding paragraph) or Debt Securities to be represented
thereafter by one or more permanent Global Notes in definitive form without
interest coupons. On or after the Exchange Date such temporary Global Note shall
be surrendered by the Common Depositary to the Trustee, as the Company's agent
for such purpose, at its principal office in London (or at such other place
specified outside the United States pursuant to Section 3.01) and following such
surrender, the Trustee shall (1) endorse the temporary Global Note to reflect
the reduction of its principal amount by an equal aggregate principal amount of
such Debt Security, (2) endorse the applicable permanent Global Note, if any, to
reflect the initial amount, or an increase in the amount of Debt Securities
represented thereby, (3) manually authenticate such definitive Debt Securities
(including any permanent Global Note), (4) deliver such definitive Debt
Securities to the Holder thereof or, if such definitive Debt Security is a
permanent Global Note, deliver such permanent Global Note to the Common
Depositary to be held outside the United States for the accounts of the
Euro-clear Operator or CEDEL, as the case may be, for credit to the respective
accounts at the Euro-clear Operator or CEDEL, as the case may be, designated by
or on behalf of the beneficial owners of such Debt Securities (or to such other
accounts as they may direct) and (5) redeliver such temporary Global Note to the
Common Depositary, unless such temporary Global Note shall have been cancelled
in accordance with Section 3.08 hereof; provided, however, that, unless
                                        --------  -------
otherwise specified in such temporary Global Note, upon such presentation by the
Common Depositary, such temporary Global Note shall be accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by the Euro-
clear Operator,
<PAGE>

                                                                              32

as to the portion of such temporary Global Note held for its account then to be
exchanged for definitive Debt Securities (including any permanent Global Note),
and a certificate dated the Exchange Date or a subsequent date and signed by
CEDEL, as to the portion of such temporary Global Note held for its account then
to be exchanged for definitive Debt Securities (including any permanent Global
Note), each substantially in the form set forth in Exhibit B to this Indenture.
Each certificate substantially in the form of Exhibit B hereto of the Euro-clear
Operator or CEDEL, as the case may be, shall be based on certificates of the
account holders listed in the records of the Euro-clear Operator or CEDEL, as
the case may be, as being entitled to all or any portion of the applicable
temporary Global Note. An account holder of the Euro-clear Operator or CEDEL, as
the case may be, desiring to effect the exchange of an interest in a temporary
Global Note for an interest in definitive Debt Securities (including any
permanent Global Note) shall instruct the Euro-clear Operator or CEDEL, as the
case may be, to request such exchange on its behalf and shall deliver to the
Euro-clear Operator or CEDEL, as the case may be, a certificate substantially in
the form of Exhibit A hereto and dated no earlier than 10 days prior to the
Exchange Date. Until so exchanged, temporary Global Notes shall in all respects
be entitled to the same benefits under this Indenture as definitive Debt
Securities (including any permanent Global Note) of the same series
authenticated and delivered hereunder, except as to payment of interest, if any.

          The delivery to the Trustee by the Euro-clear Operator or CEDEL of any
certificate substantially in the form of Exhibit B hereto may be relied upon by
the Company and the Trustee as conclusive evidence that a corresponding
certificate or certificates has or have been delivered to the Euro-clear
Operator or CEDEL, as the case may be, pursuant to the terms of this Indenture.

          On or prior to the Exchange Date, the Company shall deliver to the
Trustee definitive Debt Securities in an aggregate principal amount equal to the
principal amount of such temporary Global Note, executed by the Company. At any
time, on or after the Exchange Date, upon 30 days' notice to the Trustee by the
Euro-clear Operator or CEDEL, as the case may be, acting at the request of or on
behalf of the beneficial owner, a Debt Security represented by a temporary
Global Note or a permanent Global Note, as the case may be, may be exchanged, in
whole or from time to time in part, for definitive Debt Securities without
charge and the Trustee shall authenticate and deliver, in exchange for each
portion of such temporary Global Note or such permanent Global Note, an equal
aggregate principal amount of definitive Debt Securities of the same series of
authorized denominations and of a like Stated Maturity and with like terms and
conditions, as the portion of such temporary Global Note or such permanent
<PAGE>

                                                                              33

Global Note to be exchanged, which, unless the Debt Securities of the series are
not issuable both as Bearer Securities and as Registered Securities, as
contemplated by Section 3.01, shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof; provided, however, that definitive Bearer Securities
                          --------  -------
shall be delivered in exchange for a portion of the temporary Global Note or the
permanent Global Note only in compliance with the requirements of the second
preceding paragraph. On or prior to the forty-fifth day following receipt by the
Trustee of such notice with respect to a Debt Security, or, if such day is not a
Business Day, the next succeeding Business Day, the temporary Global Note or the
permanent Global Note, as the case may be, shall be surrendered by the Common
Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Debt Securities
without charge following such surrender, upon the request of the Euro-clear
Operator or CEDEL, as the case may be, and the Trustee shall (1) endorse the
applicable temporary Global Note or the permanent Global Note to reflect the
reduction of its principal amount by the aggregate principal amount of such Debt
Security, (2) cause the terms of such Debt Security and Coupons, if any, to be
entered on a definitive Debt Security, (3) manually authenticate such definitive
Debt Security, and (4) if a Bearer Security is to be delivered, deliver such
definitive Debt Security outside the United States to the Euro-clear Operator or
CEDEL, as the case may be, for or on behalf of the beneficial owner thereof, in
exchange for a portion of such temporary Global Note or the permanent Global
Note.

          Unless otherwise specified in such temporary Global Note or the
permanent Global Note, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Note or the permanent Global Note,
except that a Person receiving definitive Debt 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 Debt Securities in person at the
offices of the Euro-clear Operator or CEDEL. Definitive Securities in bearer
form to be delivered in exchange for any portion of a temporary Global Note or
the permanent Global Note shall be delivered only outside the United States.
Notwithstanding the foregoing, in the event of redemption or acceleration of all
or any part of a temporary Global Note prior to the Exchange Date, a permanent
Global Note or definitive Bearer Securities, as the case may be, will not be
issuable in respect of such temporary Global Note or such portion thereof, and
payment thereon will instead be made as provided in such temporary Global Note.

          Until exchanged in full as hereinabove provided, any temporary Global
Note or the permanent Global Note shall in all
<PAGE>

                                                                              34

respects be entitled to the same benefits under this Indenture as definitive
Debt Securities of the same series and tenor authenticated and delivered
hereunder, except that, unless otherwise specified as contemplated by Section
3.01, interest payable on such temporary Global Note on an Interest Payment Date
for Debt Securities of such series occurring prior to the applicable Exchange
Date shall be payable to the Euro-clear Operator or CEDEL on such Interest
Payment Date upon delivery by the Euro-clear Operator or CEDEL to the Trustee of
a certificate or certificates substantially in the form set forth in Exhibit B
to this Indenture, for credit without further interest on or after such Interest
Payment Date to the respective accounts of the Persons who are the beneficial
owners of such temporary Global Note on such Interest Payment Date and who have
each delivered to the Euro-clear Operator or CEDEL, as the case may be, a
certificate substantially in the form set forth in Exhibit A to this Indenture.

          Any definitive Bearer Security authenticated and delivered by the
Trustee in exchange for a portion of a temporary Global Note or the permanent
Global Note shall not bear a coupon for any interest which shall theretofore
have been duly paid by the Trustee to the Euro-clear Operator or CEDEL, or by
the Company to the Trustee in accordance with the provisions of this Section
3.04.

          With respect to Exhibits A and B to this Indenture, the Company may,
in its discretion and if required or desirable under applicable law, substitute
one or more other forms of such exhibits for such exhibits, eliminate the
requirement that any or all certificates be provided, or change the time that
any certificate may be required, provided that such substitute form or forms or
notice of elimination or change of such certification requirement have
theretofore been delivered to the Trustee with a Company Request and such form
or forms, elimination or change is reasonably acceptable to the Trustee.

          (c) If the Company shall establish pursuant to Section 3.01 that the
Registered Securities of a series are to be issued in whole or in part in the
form of one or more Global Notes, then the Company shall execute and the Trustee
shall, in accordance with Section 3.03 and the Company Order with respect to
such series, authenticate and deliver one or more Global Notes in temporary or
permanent form that (i) shall represent and shall be denominated in an amount
equal to the aggregate principal amount of the Outstanding Debt Securities of
such series to be represented by one or more Global Notes, (ii) shall be
registered in the name of the U.S. Depositary for such Global Note or Notes or
the nominee of such depositary, and (iii) shall bear a legend substantially to
the following effect: "This Debt Security may not be transferred except as a
whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to
<PAGE>

                                                                              35

the Depositary or another nominee of the Depositary or by the Depositary or any
such nominee to a successor Depositary or a nominee of such successor
Depositary, unless and until this Debt Security is exchanged in whole or in part
for Debt Securities in definitive form."

          Notwithstanding any other provision of this Section or Section 3.05,
unless and until it is exchanged in whole or in part for Registered Securities
in definitive form, a Global Note representing all or a portion of the
Registered Securities of a series may not be transferred except as a whole by
the U.S. Depositary for such series to a nominee of such depositary or by a
nominee of such depositary to such depositary or another nominee of such
depositary or by such depositary or any such nominee to a successor U.S.
Depositary for such series or a nominee of such successor depositary.

          If at any time the U.S. Depositary for the Debt Securities of a series
notifies the Company that it is unwilling or unable to continue as U.S.
Depositary for the Debt Securities of such series or if at any time the U.S.
Depositary for Debt Securities of a series shall no longer be a clearing agency
registered and in good standing under the Securities Exchange Act of 1934, as
amended, or other applicable statute or regulation, the Company shall appoint a
successor U.S. Depositary with respect to the Debt Securities of such series. If
a successor U.S. Depositary for the Debt Securities of such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, the Company will execute, and the Trustee,
upon receipt of a Company Order for the authentication and delivery of
definitive Debt Securities of such series, will authenticate and deliver,
Registered Securities of such series in definitive form in an aggregate
principal amount equal to the principal amount of the Global Note or Notes
representing such series in exchange for such Global Note or Notes.

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

          If the Registered Securities of any series shall have been issued in
the form of one or more Global Notes and if an Event of Default with respect to
the Debt Securities of such
<PAGE>

                                                                              36

series shall have occurred and be continuing, the Company will promptly execute,
and the Trustee, upon receipt of a Company Order for the authentication and
delivery of definitive Debt Securities of such series, will authenticate and
deliver, Registered Securities of such series in definitive form and in an
aggregate principal amount equal to the principal amount of the Global Note or
Notes representing such series in exchange for such Global Note or Notes.

          If specified by the Company pursuant to Section 3.01 with respect to
Registered Securities of a series, the U.S. Depositary for such series of
Registered Securities may surrender a Global Note for such series of Debt
Securities in exchange in whole or in part for Registered Securities of such
series in definitive form on such terms as are acceptable to the Company and
such depositary. Thereupon, the Company shall execute and the Trustee shall
authenticate and deliver, without charge:

          (i)  to each Person specified by the U.S. Depositary a new Registered
     Security or Securities of the same series, of any authorized denomination
     as requested by such Person in an aggregate principal amount equal to and
     in exchange for such Person's beneficial interest in the Global Note; and

          (ii) to the U.S. Depositary a new Global Note in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     Global Note and the aggregate principal amount of Registered Securities
     delivered to Holders thereof.

          Upon the exchange of a Global Note for Registered Securities in
definitive form, such Global Note shall be cancelled by the Trustee. Debt
Securities issued in exchange for a Global Note pursuant to this subsection (c)
shall be registered in such names and in such authorized denominations as the
U.S. Depositary for such Global Note, pursuant to instructions from its direct
or indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall make available such Debt Securities to the Persons in whose names such
Debt Securities are so registered.

                         -----------------------------------

          (a) The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the registers maintained in such office and in any
other office or agency of the Company in a Place of Payment being herein
sometimes collectively 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 of transfers and exchanges of
Registered Securities. The Trustee is hereby appointed "Security Registrar"
<PAGE>

                                                                              37

for the purpose of registering Registered Securities and registering transfers
and exchanges of Registered Securities as herein provided; provided, however,
                                                           --------  -------
that the Company may appoint co-Security Registrars.

          Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee, one or more new Registered
Securities of the same series of like aggregate principal amount of such
denominations as are authorized for Registered Securities of such series and of
a like Stated Maturity and with like terms and conditions.

          Except as otherwise provided in Section 3.04 and this Section 3.05, at
the option of the Holder, Registered Securities of any series may be exchanged
for other Registered Securities of the same series of like aggregate principal
amount and of a like Stated Maturity and with like terms and conditions, upon
surrender of the Registered Securities to be exchanged at such office or agency.
Whenever any Registered Securities are surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Registered
Securities which the Holder making the exchange is entitled to receive.

          (b) If and to the extent specified pursuant to Section 3.01, the
provisions of this Section 3.05(b) shall be applicable to Debt Securities of any
series which are Bearer Securities. At the option of the Holder thereof, to the
extent permitted by law, any Bearer Security of any series which by its terms is
registrable as to principal and interest may be exchanged for a Registered
Security of such series of like aggregate principal amount and of a like Stated
Maturity and with like terms and conditions upon surrender of such Bearer
Security at the Corporate Trust Office or at any other office or agency of the
Company designated pursuant to Section 3.01 for the purpose of making any such
exchanges. Any Coupon Security surrendered for exchange shall be surrendered
with all unmatured Coupons and any matured Coupons in default attached thereto.
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 is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such
<PAGE>

                                                                              38

payment; provided, however, that except as otherwise provided in Section 12.03,
         --------  -------
interest represented by Coupons shall be payable only upon presentation and
surrender of those Coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in exchange for a Registered
Security of the same series and of a like Stated Maturity and with like terms
and conditions after the close of business at such office or agency on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date or
proposed date for payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted Interest,
as the case may be, will not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture. The Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Security or Securities which the Holder making the
exchange is entitled to receive.

          Notwithstanding the foregoing, the exchange of Bearer Securities for
Registered Securities will be subject to the provisions of United States income
tax laws and regulations applicable to Debt Securities in effect at the time of
such exchange.

          (c) Except as otherwise specified pursuant to Section 3.01, in no
event may Registered Securities, including Registered Securities received in
exchange for Bearer Securities, be exchanged for Bearer Securities.

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

          Every Registered Security presented or surrendered for transfer or
exchange shall (if so required by the Company or the Trustee) 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.

                                                                              39

          No service charge will be made for any transfer or exchange of Debt
Securities except as provided in Section 3.04(b) or 3.06. The Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration, transfer or
exchange of Debt Securities, other than those exchanges expressly provided in
this Indenture to be made at the Company's own expense or without expense or
without charge to the Holders and not involving any transfer.

          The Company shall not be required (i) to register, transfer or
exchange Debt Securities of any series during a period beginning at the opening
of business 15 days before the day of the transmission of a notice of redemption
of Debt Securities of such series selected for redemption under Section 13.03
and ending at the close of business on the day of such transmission, or (ii) to
register, transfer or exchange any Debt Security so selected for redemption in
whole or in part, except the unredeemed portion of any Debt Security being
redeemed in part.

          Section 3.06.  Mutilated, Destroyed, Lost and Stolen Debt Securities.
                         -----------------------------------------------------

          If (i) any mutilated Debt Security or any mutilated Coupon with the
Coupon Security to which it appertains (and all unmatured Coupons attached
thereto) is surrendered to the Trustee at its Corporate Trust Office (in the
case of Registered Securities) or at its principal London office (in the case of
Bearer Securities), or (ii) the Company and the Trustee receive evidence to
their satisfaction of the destruction, loss or theft of any Debt Security or any
Coupon, and there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to save each of them and any Paying Agent
harmless, and neither the Company nor the Trustee receives notice that such Debt
Security or Coupon has been acquired by a bona fide purchaser, then the Company
shall execute and upon Company Request the Trustee shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Debt Security or in exchange for the Coupon Security to which such
mutilated, destroyed, lost or stolen Coupon appertained, a new Debt Security of
the same series of like Stated Maturity and with like terms and conditions and
like principal amount, bearing a number not contemporaneously Outstanding, and,
in the case of a Coupon Security, with such Coupons attached thereto that
neither gain nor loss in interest shall result from such exchange or
substitution.

          In case any such mutilated, destroyed, lost or stolen Debt Security or
Coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Debt Security, pay the amount due on
such Debt Security or
<PAGE>

                                                                              40

Coupon in accordance with its terms; provided, however, that principal of (and
                                     --------  -------
premium, if any) and any interest on Bearer Securities shall, except as
otherwise provided in Section 12.03, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 3.01 or except as otherwise provided in this Section
3.06, any interest on Bearer Securities shall be payable only upon presentation
and surrender of the Coupons appertaining thereto.

          Upon the issuance of any new Debt 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 respect thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Debt Security or Coupon of any series issued pursuant to
this Section shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Debt Security or
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 Debt Securities or Coupons of that series duly issued hereunder.

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

          Section 3.07.  Payment of Interest; Interest Rights Preserved.
                         ----------------------------------------------

          (a) Interest on any Registered Security which is payable and is
punctually paid or duly provided for on any Interest Payment Date shall be paid
to the Person in whose name such Registered Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest notwithstanding the cancellation of such Registered Security
upon any transfer or exchange subsequent to the Regular Record Date. Unless
otherwise specified as contemplated by Section 3.01 with respect to the Debt
Securities of any series, payment of interest on Registered Securities shall be
made at the place or places specified pursuant to Section 3.01 or, at the option
of the Company, by check mailed to the address of the Person entitled thereto as
such address shall appear in the Security Register or, if provided pursuant to
Section 3.01, by wire transfer to an account designated by the Registered
Holder.

          (b) Interest on any Coupon Security which is payable and is punctually
paid or duly provided for on any Interest Payment Date shall be paid to the
Holder of the Coupon which has
<PAGE>

                                                                              41

matured on such Interest Payment Date upon surrender of such Coupon on such
Interest Payment Date at the principal London office of the Trustee or at such
other Place of Payment outside the United States specified pursuant to Section
3.01.

          Interest on any Bearer Security (other than a Coupon Security) which
is payable and is punctually paid or duly provided for on any Interest Payment
Date shall be paid to the Holder of the Bearer Security upon presentation of
such Bearer Security and notation thereon on such Interest Payment Date at the
principal London office of the Trustee or at such other Place of Payment outside
the United States specified pursuant to Section 3.01.

          Unless otherwise specified pursuant to Section 3.01, at the direction
of the Holder of any Bearer Security or Coupon payable in Dollars, payment on
such Bearer Security or Coupon will be made by check drawn on a bank in The City
of New York or, if agreeable to the Trustee, by wire transfer to a Dollar
account maintained by such Holder outside the United States. If such payment at
the offices of all Paying Agents outside the United States becomes illegal or is
effectively precluded because of the imposition of exchange controls or similar
restrictions on the full payment or receipt of such amounts in Dollars, the
Company will appoint an office or agent in the United States at which such
payment may be made. Unless otherwise specified pursuant to Section 3.01, at the
direction of the Holder of any Bearer Security or Coupon payable in a Foreign
Currency, payment on such Bearer Security or Coupon will be made by a check
drawn on a bank outside the United States or by wire transfer to an appropriate
account maintained by such Holder outside the United States. Except as provided
in this paragraph, no payment on any Bearer Security or Coupon will be made by
mail to an address in the United States or by wire transfer to an account in the
United States.

          (c) Any interest on any Debt Security which is payable but is not
punctually paid or duly provided for on any interest Payment Date (herein called
"Defaulted Interest") shall, if such Debt Security is a Registered Security,
forthwith cease to be payable to the Registered Holder on the relevant Regular
Record Date by virtue of his having been such Registered Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names 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
<PAGE>

                                                                              42

     Defaulted Interest proposed to be paid on each such 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 in the Currency or Currency
     unit in which the Debt Securities of such series are payable (except as
     otherwise specified pursuant to Sections 3.01 or 3.10) 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 date
     shall be not more than 15 days and not less than 10 days prior to the date
     of the proposed payment and not less than 10 days after the receipt by the
     Trustee of the notice of the proposed payment. The Trustee shall promptly
     notify the Company of such Special Record Date and, in the name and at the
     expense of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to the Holders of such Registered Securities
     at their addresses as they appear 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 at the close of business on such Special Record
     Date and shall no longer be payable pursuant to the following clause (2).

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

          (d) Any Defaulted Interest payable in respect of Bearer Securities of
any series shall be payable pursuant to such procedures as may be satisfactory
to the Trustee in such manner that there is no discrimination between the
Holders of Registered Securities (if any) and Bearer Securities of such series,
and notice of the payment date therefor shall be given by the Trustee, in the
name and at the expense of the Company, in the manner provided in Section 1.O5
not more than 25 days and not less than 20 days prior to the date of the
proposed payment.
<PAGE>

                                                                              43

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

          In the case of any Registered Security of any series that is
convertible, which Registered Security is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Registered Security whose Maturity is prior to such Interest Payment Date),
interest whose Stated Maturity is on such Interest Payment Date shall be payable
on such Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Registered Security (or one or more predecessor
Registered Securities) is registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Registered Security which is converted, interest
whose Stated Maturity is after the date of conversion of such Registered
Security shall not be payable.

          Section 3.08.  Cancellation.
                         ------------

          Unless otherwise specified pursuant to Section 3.01 for Debt
Securities of any series, all Debt Securities surrendered for payment,
redemption, transfer, exchange or credit against any sinking fund and all
Coupons surrendered for payment or exchange shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee. All Debt Securities and
matured Coupons so delivered shall be promptly cancelled by the Trustee. The
Company may at any time deliver to the Trustee for cancellation any Debt
Securities or Coupons previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Debt Securities previously authenticated hereunder which the Company has not
issued, and all Debt Securities or Coupons so delivered shall be promptly
cancelled by the Trustee. No Debt Securities or Coupons shall be authenticated
in lieu of or in exchange for any Debt Securities or Coupons cancelled as
provided in this Section, except as expressly permitted by this Indenture. All
cancelled Debt Securities and Coupons held by the Trustee shall be destroyed by
the Trustee unless the Company shall request otherwise. The acquisition of any
Debt Securities or Coupons by the Company shall not operate as a redemption or
satisfaction of the indebtedness represented thereby unless and until such Debt
Securities or Coupons are surrendered to the Trustee for cancellation. In the
case of any temporary Global Note which shall be destroyed if the entire
aggregate principal amount of the Debt Securities represented thereby has been
exchanged, the certificate of destruction shall state that all certificates
required pursuant to Section 3.04 hereof and substantially in the form of
Exhibit B hereto, to be given by the Euro-clear Operator or CEDEL, have been
duly presented to the Trustee by the Euro-clear Operator or CEDEL, as the case
may be. Permanent Global Notes shall not be destroyed until exchanged in full
for definitive Debt Securities or until payment thereon is made in full.

          Section 3.09.  Computation of Interest.
                         -----------------------

          Except as otherwise specified pursuant to Section 3.01 for Debt
Securities of any series, interest on the Debt Securities of each series shall
be computed on the basis of a 360-day year of twelve 30-day months.

                         --------------------------------------------------

          (a)  Except as otherwise specified pursuant to Section 3.01 for Bearer
Securities of any series, payment of the
<PAGE>

                                                                              45

principal of (and premium, if any) and interest on Bearer Securities of such
series denominated in any Currency will be made in such Currency.

          (b) With respect to Registered Securities of any series not permitting
the election provided for in paragraph (c) below or the Holders of which have
not made the election provided for in paragraph (c) below, except as provided in
paragraph (e) below, payment of the principal of (and premium, if any) and any
interest on any Registered Security of such series will be made in the Currency
in which such Registered Security is payable.

          (c) It may be provided pursuant to Section 3.01 with respect to the
Registered Securities of any series that Holders shall have the option, subject
to paragraphs (e) and (f) below, to receive payments of principal of (and
premium, if any) and any interest on such Registered Securities in any of the
Currencies which may be designated for such election by delivering to the
Trustee a written election, to be in form and substance satisfactory to the
Trustee, not later than the close of business on the Election Date immediately
preceding the applicable payment date. If a Holder so elects to receive such
payments in any such Currency, such election will remain in effect for such
Holder or any transferee of such Holder until changed by such Holder or such
transferee by written notice to the Trustee (but any such change must be made
not later than the close of business on the Election Date immediately preceding
the next payment date to be effective for the payment to be made on such payment
date and no such change or election may be made with respect to payments to be
made on any Registered Security of such series with respect to which an Event of
Default has occurred or notice of redemption has been given by the Company
pursuant to Article Thirteen). Any Holder of any such Registered Security who
shall not have delivered any such election to the Trustee by the close of
business on the applicable Election Date will be paid the amount due on the
applicable payment date in the relevant Currency as provided in paragraph (b) of
this Section 3.10.

          (d) If the election referred to in paragraph (c) above has been
provided for pursuant to Section 3.01, then not later than the fourth Business
Day after the Election Date for each payment date, the Trustee will deliver to
the Company a written notice specifying, in the Currency in which each series of
the Registered Securities is payable, the respective aggregate amounts of
principal of (and premium, if any) and any interest on the Registered Securities
to be paid on such payment date, specifying the amounts so payable in respect of
the Registered Securities as to which the Holders of Registered Securities
denominated in any Currency shall have elected to be paid in another Currency as
provided in paragraph (c) above. If the election referred to in paragraph (c)
above has been provided for pursuant to Section 3.01 and if at least one Holder
has made such
<PAGE>

                                                                              46

election, then, on the second Business Day preceding each payment date, the
Company will deliver to the Trustee an Exchange Rate Officer's Certificate in
respect of the Currency payments to be made on such payment date. The Currency
amount receivable by Holders of Registered Securities who have elected payment
in a Currency as provided in paragraph (c) above shall be determined by the
Company on the basis of the applicable Market Exchange Rate in effect on the
third Business Day (the "Valuation Date") immediately preceding each payment
date.

          (e) If a Conversion Event occurs with respect to a Foreign Currency,
the ECU or any other Currency unit in which any of the Debt Securities are
denominated or payable other than pursuant to an election provided for pursuant
to paragraph (c) above, then with respect to each date for the payment of
principal of (and premium, if any) and any interest on the applicable Debt
Securities denominated or payable in such Foreign Currency, the ECU or such
other Currency unit occurring after the last date on which such Foreign
Currency, the ECU or such other Currency unit was used (the "Conversion Date"),
the Dollar shall be the Currency of payment for use on each such payment date.
The Dollar amount to be paid by the Company to the Trustee and by the Trustee or
any Paying Agent to the Holders of such Debt Securities with respect to such
payment date shall be the Dollar Equivalent of the Foreign Currency or, in the
case of a Currency unit, the Dollar Equivalent of the Currency Unit, in each
case as determined by the Currency Determination Agent in the manner provided in
paragraph (g) or (h) below.

          (f) If the Holder of a Registered Security denominated in any Currency
shall have elected to be paid in another Currency as provided in paragraph (c)
above, and a Conversion Event occurs with respect to such elected Currency, such
Holder shall receive payment in the Currency in which payment would have been
made in the absence of such election. If a Conversion Event occurs with respect
to the Currency in which payment would have been made in the absence of such
election, such Holder shall receive payment in Dollars as provided in paragraph
(e) of this Section 3.10.

          (g) The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Currency Determination Agent and shall be obtained for each
subsequent payment date by converting the specified Foreign Currency into
Dollars at the Market Exchange Rate on the Conversion Date.

          (h) The "Dollar Equivalent of the Currency Unit" shall be determined
by the Currency Determination Agent, and subject to the provisions of paragraph
(i) below, shall be the sum of each amount obtained by converting the Specified
Amount of each Component Currency into Dollars at the Market Exchange Rate for
such Component Currency on the Valuation Date with respect to each payment.
<PAGE>

                                                                              47

          (i) For purposes of this Section 3.10 the following terms shall have
the following meanings:

          A "Component Currency" shall mean any Currency which, on the
     Conversion Date, was a component Currency of the relevant Currency unit,
     including, but not limited to, the ECU.

          A "Specified Amount" of a Component Currency shall mean the number of
     units of such Component Currency or fractions thereof which were
     represented in the relevant Currency unit, including, but not limited to,
     the ECU, on the Conversion Date. If after the Conversion Date the official
     unit of any Component Currency is altered by way of combination or
     subdivision, the Specified Amount of such Component Currency shall be
     divided or multiplied in the same proportion. If after the Conversion Date
     two or more Component Currencies are consolidated into a single Currency,
     the respective Specified Amounts of such Component Currencies shall be
     replaced by an amount in such single Currency equal to the sum of the
     respective Specified Amounts of such consolidated Component Currencies
     expressed in such single Currency, and such amount shall thereafter be a
     Specified Amount and such single Currency shall thereafter be a Component
     Currency. If after the Conversion Date any Component Currency shall be
     divided into two or more Currencies, the Specified Amount of such Component
     Currency shall be replaced by amounts of such two or more Currencies with
     appropriate Dollar equivalents at the Market Exchange Rate on the date of
     such replacement equal to the Dollar equivalent of the Specified Amount of
     such former Component Currency at the Market Exchange Rate on such date,
     and such amounts shall thereafter be Specified Amounts and such Currencies
     shall thereafter be Component Currencies. If after the Conversion Date of
     the relevant Currency unit, including but not limited to, the ECU, a
     Conversion Event (other than any event referred to above in this definition
     of "Specified Amount") occurs with respect to any Component Currency of
     such Currency unit, the Specified Amount of such Component Currency shall,
     for purposes of calculating the Dollar Equivalent of the Currency Unit, be
     converted into Dollars at the Market Exchange Rate in effect on the
     Conversion Date of such Component Currency.

          "Election Date" shall mean the record date with respect to any payment
     date, and with respect to the Maturity shall mean the record date (if
     within 16 or fewer days prior to the Maturity) immediately preceding the
     Maturity, and with respect to any series of Debt Securities whose record
     date immediately preceding the Maturity is more than 16 days prior to the
     Maturity or any series of Debt Securities for which no record dates are
     provided with respect to interest
<PAGE>

                                                                              48

     payments, shall mean the date which is 16 days prior to the Maturity.

          (j) All decisions and determinations of the Currency Determination
Agent regarding the Dollar Equivalent of the Foreign Currency, the Dollar
Equivalent of the Currency Unit and the Market Exchange Rate shall be in its
sole discretion and shall, in the absence of manifest error, be conclusive for
all purposes and irrevocably binding upon the Company and all Holders of the
Debt Securities denominated or payable in the relevant Currency. In the event of
a Conversion Event with respect to a Foreign Currency, the Company, after
learning thereof, will immediately give written notice thereof to the Trustee
(and the Trustee will promptly thereafter give notice in the manner provided in
Section 1.05 to the Holders) specifying the Conversion Date. In the event of a
Conversion Event with respect to the ECU or any other Currency unit in which
Securities are denominated or payable, the Company, after learning thereof, will
immediately give notice thereof to the Trustee (and the Trustee will promptly
thereafter give written notice in the manner provided in Section 1.05 to the
Holders) specifying the Conversion Date and the Specified Amount of each
Component Currency on the Conversion Date. In the event of any subsequent change
in any Component Currency as set forth in the definition of Specified Amount
above, the Company, after learning thereof, will similarly give written notice
to the Trustee. The Trustee shall be fully justified and protected in relying
and acting upon information received by it from the Company and the Currency
Determination Agent and shall not otherwise have any duty or obligation to
determine such information independently.

          (k) For purposes of any provision of the Indenture where the Holders
of Outstanding Debt Securities may perform an Act which requires that a
specified percentage of the Outstanding Debt Securities of all series perform
such Act and for purposes of any decision or determination by the Trustee of
amounts due and unpaid for the principal (and premium, if any) and interest on
the Debt Securities of all series in respect of which moneys are to be disbursed
ratably, the principal of (and premium, if any) and interest on the Outstanding
Debt Securities denominated in a Foreign Currency will be the amount in Dollars
based upon the Market Exchange Rate for Debt Securities of such series, as of
the date for determining whether the Holders entitled to perform such Act have
performed it, or as of the date of such decision or determination by the
Trustee, as the case may be.

          Section 3.11.  Judgments.
                         ---------

          If for the purpose of obtaining a judgment in any court with respect
to any obligation of the Company hereunder or under any Debt Security, it shall
become necessary to convert into any other Currency any amount in the Currency
due hereunder or under
<PAGE>

                                                                              49

such Debt Security, then such conversion shall be made at the Market Exchange
Rate as in effect on the date the Company shall make payment to any Person in
satisfaction of such judgment. If pursuant to any such judgment, conversion
shall be made on a date other than the date payment is made and there shall
occur a change between such Market Exchange Rate and the Market Exchange Rate as
in effect on the date of payment, the Company agrees to pay such additional
amounts (if any) as may be necessary to ensure that the amount paid is equal to
the amount in such other Currency which, when converted at the Market Exchange
Rate as in effect on the date of payment or distribution, is the amount then due
hereunder or under such Debt Security. Any amount due from the Company under
this Section 3.11 shall be due as a separate debt and is not to be affected by
or merged into any judgment being obtained for any other sums due hereunder or
in respect of any Debt Security. In no event, however, shall the Company be
required to pay more in the Currency or Currency unit due hereunder or under
such Debt Security at the Market Exchange Rate as in effect when payment is made
than the amount of Currency stated to be due hereunder or under such Debt
Security so that in any event the Company's obligations hereunder or under such
Debt Security will be effectively maintained as obligations in such Currency,
and the Company shall be entitled to withhold (or be reimbursed for, as the case
may be) any excess of the amount actually realized upon any such conversion over
the amount due and payable on the date of payment or distribution.

          Section 3.12.  Exchange Upon Default.
                         ---------------------

          If default is made in the payments referred to in Section 12.01, the
Company hereby undertakes that upon presentation and surrender of a permanent

maturity date thereof the Company will issue and the Trustee will authenticate
and deliver to the bearer or holder of such permanent Global Note duly executed
and authenticated definitive Debt Securities with the same issue date and

                         -------------

          The Company in issuing the Securities may use "CUSIP" numbers (if then

the deposit pursuant to Section 4.01 was made, or (y) if a Conversion Event
occurs with respect to the Currency in which the deposit was made or elected to
be received by the Holder pursuant to Section 3.10(c), then the indebtedness
represented by such Debt Security shall be fully discharged to the extent that
the deposit made with respect to such Debt Security shall be converted into the
Currency in which such payment is made.

     default in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which expressly has been included in this
     Indenture solely for the benefit of Debt Securities of a series other than
     such series), and continuance of such default or breach for a period of 90
     days after there has been given, by registered or certified mail, to the
     Company by the Trustee or to the Company and the Trustee by the Holders of
     at least 25% in principal amount of the Outstanding Debt Securities of such
     series, a written notice specifying such default or breach and requiring it

     default is in excess of $10,000,000, and such acceleration shall not have
     been rescinded or annulled, or such Indebtedness shall not have been
     discharged, within a period of 30 days after there has been given, by
     registered or certified mail, to the Company by the Trustee or to the
     Company and the Trustee by the Holders of at least 25% in principal amount
     of the Outstanding Debt Securities of such series, a written notice
     specifying such default or defaults and stating that such notice is a
     "Notice of Default" hereunder; or

          (5) the entry of a decree or order for relief in respect of the
     Company by a court having jurisdiction in the premises in an involuntary
     case under the Federal bankruptcy laws, as now or hereafter constituted, or
     any other applicable Federal or State bankruptcy, insolvency or other
     similar law, or a decree or order adjudging the Company a bankrupt or
     insolvent, or approving as properly filed a petition seeking
     reorganization, arrangement, adjustment or composition of or in respect of
     the Company under any applicable Federal or State law, or appointing a
     receiver, liquidator, assignee, custodian, trustee, sequestrator (or other
     similar official) of the Company or of any substantial part of its
     property, or ordering the winding up or liquidation of its affairs, and the
     continuance of any such decree or order unstayed and in effect for a period
     of 60 consecutive days; or

          (6) the commencement by the Company of a voluntary case under the
     Federal bankruptcy laws, as now or hereafter constituted, or any other
     applicable Federal or State bankruptcy, insolvency or other similar law, or
     the consent by it to the entry of an order for relief in an involuntary
     case under any such law or to the appointment of a receiver, liquidator,
     assignee, custodian, trustee, sequestrator (or other similar official) of
     the Company or of any substantial part of its property, or the making by it
     of an assignment for the benefit of its creditors, or the admission by it
     in writing of its inability to pay its debts generally as they become due,
     or the taking of corporate action by the Company in furtherance of any such
     action; or

          (7) any other Event of Default provided with respect to Debt
     Securities of that series pursuant to clause (21) of Section 3.01.

          Section 5.02.  Acceleration of Maturity; Rescission and Annulment.
                         --------------------------------------------------

          If an Event of Default with respect to Debt Securities of any series
at the time Outstanding occurs and is continuing,
<PAGE>

                                                                              54

then in every such case the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Debt Securities of such series may declare
the principal amount (or, if any Debt Securities of such series are Discount
Securities, such portion of the principal amount of such Discount Securities as
may be specified in the terms of such Discount Securities) of all the Debt
Securities of such series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. Upon payment of such amount in the Currency in
which such Debt Securities are payable (except as otherwise provided pursuant to
Sections 3.01 or 3.10), all obligations of the Company in respect of the payment
of principal of the Debt Securities of such series shall terminate.

          At any time after such a declaration of acceleration with respect to
Debt 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 Debt Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

          (1) the Company has paid or deposited with the Trustee a sum in the
     Currency in which such Debt Securities are payable (except as otherwise
     provided pursuant to Section 3.01 or 3.10) sufficient to pay

          (A)  all overdue installments of interest on all Debt Securities or
               all overdue payments with respect to any Coupons of such series,

          (B)  the principal of (and premium, if any, on) any Debt 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 in such Debt Securities,

          (C)  to the extent that payment of such interest is lawful, interest
               upon overdue installments of interest on each Debt Security of
               such series or upon overdue payments on any Coupons of such
               series at the Overdue Rate, and

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

and

          (2) All Events of Default with respect to Debt Securities of such
     series, other than the nonpayment of the principal of Debt Securities of
     such series which has become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 5.13.

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

Trustee.
-------

          The Company covenants that if

          (1) default is made in the payment of any installment of interest on
     any Debt Security or any payment with respect to any Coupons when such
     interest or payment becomes due and payable and such default continues for
     a period of 30 days, or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debt Securities or of such Coupons, the amount then due and
payable on such Debt Securities or matured Coupons, for the principal (and
premium, if any) and interest, if any, and, to the extent that payment of such
interest shall be legally enforceable, interest upon the overdue principal (and
premium, if any) and upon overdue installments of interest, at the Overdue Rate;
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel
other than any such compensation, expenses, disbursement, or advances which
result from the Trustee's negligence or bad faith.

          If the Company fails to pay such amount 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 Debt Securities and Coupons,
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 Debt
Securities and Coupons wherever situated.

          If an Event of Default with respect to Debt Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Debt Securities and
Coupons 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.

bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceedings, or any voluntary or involuntary case under the Federal
bankruptcy laws, as now or hereafter constituted, relative to the Company or any
other obligor upon the Debt Securities and Coupons, if any, of a particular
series or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of such Debt
Securities shall then be due and payable as therein expressed or by declaration
of acceleration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue principal 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 (or,
     if the Debt Securities of such series are Discount Securities, such portion
     of the principal amount as may be due and payable with respect to such
     series pursuant to a declaration in accordance with Section 5.02) (and
     premium, if any) and interest owing and unpaid in respect of the Debt
     Securities and Coupons of such series 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 other
     than any such compensation, expenses, disbursements and advances which
     result from the Trustee's negligence or bad faith) and of the Holders of
     such Debt Securities and Coupons 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, custodian, liquidator, sequestrator (or
other similar official) in any such proceeding is hereby authorized by each such
Holder to make such payments to the Trustee, and in the event that the Trustee
shall consent to

Trustee under Section 6.07 other than any such compensation, expenses,
disbursements and advances which result from the Trustee's negligence or bad
faith.

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

Securities and the Coupons, if any, of any series may be prosecuted and enforced
by the Trustee without the possession of any of such Debt Securities or Coupons
or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name, as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel other than any such
compensation, expenses, disbursements and advances which result from the
Trustee's negligence or bad faith, be for the ratable benefit of the Holders of
the Debt Securities or Coupons in respect of which such judgment has been
recovered.

          No Holder of any Debt Security or Coupon of any series shall have any
right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

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

          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Debt Securities of such series shall have made written request
     to the Trustee to institute proceedings in respect of such Event of Default
     in its own name as Trustee hereunder;

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other such
Holders or of the Holders of Outstanding Debt Securities or Coupons of any other
series, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all of such
Holders. For the protection and enforcement of the provisions of this Section
5.07, each and every Holder of Debt Securities or Coupons of any series and the
Trustee for such series shall be entitled to such relief as can be given at law

respective Stated Maturity or Maturities expressed in such Debt Security or

                         ------------------------------

          Except as otherwise expressly provided elsewhere in this Indenture, 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

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 Debt
Securities of such series, provided, that

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

          (2) subject to the provisions of Section 6.01, 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 Responsible Officers of the

     interest on any Debt Security of such series, or

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

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of the Debt 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.

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 other

court may in its discretion assess reasonable costs, including reasonable
attorneys' fees and expenses, 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 had 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

enforcement of the payment of the principal of (or premium, if any) or interest
on such Debt Security or the payment of any Coupon on or after the respective
Stated Maturity or Maturities expressed in such Debt Security or Coupon (or, in
the case of redemption, on or after the Redemption Date).

          Section 6.01.  Certain Duties and Responsibilities.
                         -----------------------------------

          (a)  Except during the continuance of an Event of Default with respect
to the Debt Securities of any series,

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

          (2)  in the absence of bad faith on its part, the Trustee may
     conclusively rely, 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 certificates or opinions which by any provisions
     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 to the requirements of this Indenture, but need not
     confirm or investigate the accuracy of any mathematical calculations or
     other facts stated therein.

          (b)  In case an Event of Default with respect to Debt Securities of
any series has occurred and is continuing, the Trustee shall, with respect to
the Debt Securities of such series, exercise such of the rights and powers
vested in it by
<PAGE>

                                                                              62

this Indenture, and use the same degree of care and skill in their exercise, as
a prudent man would exercise or use under the circumstances in the conduct of
his own affairs. Notwithstanding the foregoing, the Trustee shall not be
required to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers.

          (c) 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 willful misconduct, except that

          (1) this subsection shall not be construed to limit the effect of
     subsection (a) of this Section;

          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts; and

          (3) the Trustee shall not be liable with respect to any action taken,
     suffered or omitted to be taken by it with respect to Debt Securities of
     any series in good faith in accordance with the direction of the Holders of
     a majority in principal amount of the Outstanding Debt Securities of such
     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.

          (d) 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.

such default shall have been cured or waived; provided, however, that, except in

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 determine that the withholding of such notice is in the interest of the
Holders of Debt Securities and of Coupons of such series; and provided, further,
                                                              --------  -------
that in the case of any default of the character specified in Section 5.01(3)
with respect to Debt Securities of such series, no such notice to Holders shall
be given until at least 45 days after the occurrence thereof. For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to Debt
Securities of such series.

          Notice given pursuant to this Section 6.02 shall be transmitted by

     two years preceding such transmission, filed their names and addresses with
     the Trustee for such series for that purpose; and

          (3) to each Holder of a Debt Security of any series whose name and

(whether in its original or facsimile form) believed by it to be genuine and to
have been signed or presented by the proper party or parties;

          (b) 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 shall be sufficiently evidenced by a Board Resolution;

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;

          (d) the Trustee may consult with counsel of its own selection and the

by it hereunder in good faith and in reliance thereon;

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

          (f) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, unless
requested in writing to do so by the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series; provided, however,
                                                              --------  -------
that if the payment within a reasonable time to the Trustee of the costs,
expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity satisfactory to it against such costs,
expenses or liabilities as a condition to so proceeding;

          (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or

          (h) the Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Reponsible Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a default is
received by the Trustee at the Corporate Trust Office of the Trustee, and such
notice references the Securities and the Indenture; and

          (i) the rights, privileges, protections, immunities and benefits given
to the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and to each agent, custodian and other Person employed to act

money received by it hereunder except as otherwise agreed with the Company.

          Section 6.07.  Compensation and Reimbursement.
                         ------------------------------

          (1)  to pay to the Trustee such compensation as shall be agreed upon

          (2)  except as otherwise expressly provided herein, to reimburse the
     Trustee in Dollars upon its request for all expenses, disbursements and

     disbursement or advance as may result from its negligence or willful
     misconduct; and

          (3)  to fully indemnify in Dollars the Trustee for, and to hold it
     harmless against, any and all loss, liability, damage or expense (including

defined in 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. The

purposes of clause (1) of the first proviso contained in Section 310(b) of the
Trust Indenture Act: the Indenture dated as of June 15, 1985 between the Company
and Trustee providing for the issuance of an unlimited amount of unsecured debt

become effective until the acceptance of appointment by the successor Trustee
under Section 6.11.

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

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

          (d)  If at any time:

          (1) the Trustee shall fail to comply with Section 6.08 with respect to
     the Debt Securities of any series after written request therefor by the
     Company or by any Holder who has been a bona fide Holder of a Debt Security
     of such series for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.09 with
     respect to the Debt Securities of any series and shall fail to resign after
     written request therefor by the Company or by any such Holder, or

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

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee with respect to all Debt Securities, or (ii) subject to
Section 5.14, any Holder who has been a bona fide Holder of a Debt Security of
any 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 for the Debt
Securities of such series.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Debt Securities of one or more series, the Company, by or
pursuant to a Board Resolution, shall promptly appoint a successor Trustee or

Trustees with respect to the Debt Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the
Debt 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 Debt Securities of any particular
series) and shall comply with the applicable requirements of Section 6.11. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee with respect to the Debt
Securities of any series shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Debt Securities of such series delivered
to the Company and the retiring Trustee, the successor Trustee so appointed
shall, forthwith upon its acceptance of such appointment, become the successor
Trustee with respect to the Debt Securities of such series and to that extent
supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Debt Securities of any series shall have been so
appointed by the Company or the Holders of such series and accepted appointment
in the manner hereinafter provided, any Holder who has been a bona fide Holder
of a Debt Security of such series for at least six months may, subject to
Section 5.14, 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 the Debt Securities of such series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Debt Securities of any series and each
appointment of a successor Trustee with respect to the Debt Securities of any
series in the manner and to the extent provided in Section 1.05 to the Holders
of Debt Securities of such series. Each notice shall include the name of the

          (a) In the case of an appointment hereunder of a successor Trustee
with respect to all Debt Securities, each 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 and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee, but, on
request of the Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring
Trustee, and shall duly assign, transfer and deliver to such successor Trustee
all property and money held by such

retiring Trustee hereunder, subject nevertheless to its claim, if any, provided
for in Section 6.07.

          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Debt Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Debt
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Debt Securities of that or those series to which the appointment of such
successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Debt 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 Debt Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be
vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in any 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 other trust or trusts hereunder administered by any other such Trustee and
that no Trustee shall be responsible for any notice given to or received by or
any act or failure to act on the part of any other Trustee hereunder; and upon
the execution and delivery of any 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 Debt 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 Debt
Securities of that or those series to which the appointment of such successor
Trustee relates.

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

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

                         --------------------------------------------------
Business.

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided 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 Debt 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 Debt Securities so authenticated
with the same effect as if such successor Trustee had itself authenticated such
Debt Securities. In case any Debt Securities shall not have been authenticated
by such predecessor Trustee, any such successor Trustee may authenticate and
deliver such Debt Securities, in either its own name or that of its predecessor
Trustee, with the full force and effect which this Indenture provides for the
certificate of authentication of the Trustee.

          Section 6.13.  Preferential Collection of Claims Against Company.
                         -------------------------------------------------

          If and when the Trustee shall be or become a creditor of the Company
(or any obligor upon the Debt Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such obligor).

          Section 6.14.  Appointment of Authenticating Agent.
                         -----------------------------------

          As long as any Debt Securities of a series remain Outstanding, upon a
Company Request, there shall be an authenticating agent (the "Authenticating
Agent") appointed, for such period as the Company shall elect, by the Trustee
for such series of Debt Securities to act as its agent on its behalf and subject
to its direction in connection with the authentication and delivery of each
series of Debt Securities for which it is serving as Trustee. Debt Securities of
each such series authenticated by such Authenticating Agent shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by such Trustee. Wherever reference is made in this
Indenture to the authentication and

                                                                              71

delivery of Debt Securities of any series by the Trustee for such series or to
the Trustee's Certificate of Authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee for such series by
an Authenticating Agent for such series and a Certificate of Authentication
executed on behalf of such Trustee by such Authenticating Agent, except that
only the Trustee may authenticate Debt Securities upon original issuance and
pursuant to Section 3.06 hereof. Such Authenticating Agent shall at all times be
a corporation organized and doing business under the laws of the United States
of America or of any State, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $10,000,000 and
subject to supervision or examination by Federal or State authority. 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 purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. 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 any 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 any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the Authenticating Agent with
respect to all series of Debt Securities for which it served as Authenticating
Agent without the execution or filing of any paper or any further act on the
part of the Trustee for such series or such Authenticating Agent. Any
Authenticating Agent may at any time, and if it shall cease to be eligible
shall, resign by giving written notice of resignation to the applicable Trustee
and to the Company.

          Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section 6.14 with respect to
one or more or all series of Debt Securities, the Trustee for such series shall
upon Company Request appoint a successor Authenticating Agent, and the Company
shall provide notice of such appointment to all Holders of Debt Securities of
such series in the manner and to the extent provided in Section 1.05. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all rights, powers, duties and responsibilities of its
predecessor hereunder, with like effect as if originally named as Authenticating
Agent herein. The Trustee for the Debt

Securities of such series agrees to pay to the Authenticating Agent for such
series from time to time reasonable compensation for its services, and the
Trustee shall be entitled to be reimbursed for such payment, subject to the
provisions of Section 6.07. The Authenticating Agent for the Debt Securities of
any series shall have no responsibility or liability for any action taken by it
as such at the direction of the Trustee for such series.

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

          This is one of the series of Debt Securities issued under the within
mentioned Indenture.

Company may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be
effective. The Trustee shall not be liable for any action taken by, or omission
of, the Trustee in accordance with a proposal included in such application on or
after the date specified in such application (which date shall not be less than
five Business Days after the date any officer of the Company actually receives
such application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

          The Company will furnish or cause to be furnished to the Trustee with
respect to Registered Securities of each series for which it acts as Trustee:

          (a) semi-annually on a date not more than 15 days after each Regular
Record Date with respect to an Interest Payment Date, if any, for the Registered
Securities of such series (or on semi-annual dates in each year to be determined
pursuant to Section 3.01 if the Registered Securities of such series do not bear
interest), a list, in such form as the Trustee may reasonably require, of the
names and addresses of the Registered Holders as of the date 15 days next
preceding each such Regular Record Date (or such semi-annual dates, as the case
may be); and

                                                                              73

          (b)  at such other times as the Trustee may request in writing, within
30 days after the 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 furnished;

provided, however, that if and so long as the Trustee shall be the Security
--------  -------
Registrar for such series, no such list need be furnished.

          The Company shall also be required to furnish to the Trustee at all
such times set forth above all information in the possession or control of the
Company or any of its Paying Agents other than the Trustee as to the names and
addresses of the Holders of Bearer Securities of all series; provided, however,
                                                             --------  -------
that the Company shall have no obligation to investigate any matter relating to
any Holders of Bearer Securities of any series.

          Section 7.02.  Preservation of Information; Communication to Holders.
                         -----------------------------------------------------

          (a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, all information as to the names and addresses of Holders contained
in the most recent list furnished to the Trustee as provided in Section 7.01
received by it in the capacity of Paying Agent (if so acting) hereunder, and
filed with it within the two preceding years pursuant to Section 7.03(c)(2).

          The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished, destroy any information
received by it as Paying Agent (if so acting) hereunder upon delivering to
itself as Trustee, not earlier than 45 days after an Interest Payment Date, a
list containing the names and addresses of the Holders obtained from such
information since the delivery of the next previous list, if any, destroy any
list delivered to itself as Trustee which was compiled from information received
by it as Paying Agent (if so acting) hereunder upon the receipt of a new list so
delivered, and destroy not earlier than two years after filing, any information
filed with it pursuant to Section 7.03(c)(2).

          (b)  If three or more Holders (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 Debt Security 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 Debt Securities of a particular series (in which case the applicants must
hold Debt Securities of such series) or with all Holders of Debt Securities with
respect to their rights under this Indenture or under the Debt Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants

                                                                              74

propose to transmit, then the Trustee shall, within five Business Days after the
receipt of such application, at its election, either

          (i)  afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), or

          (ii) inform such applicants as to the approximate number of Holders of
     Debt Securities of such series or of all Debt 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 7.02(a), and as to the
     approximate cost of mailing to such Holders the form of proxy or other
     communication, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon written inquest of such applicants,
mail to the Holders of Debt Securities of such series or all Holders, as the
case may be, whose names and addresses appear in the information preserved at
the time by the Trustee in accordance with Section 7.02(a), 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 Debt Securities of such series or all Holders, as the case may be, or would
be in violation of applicable law. Such written 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 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.

          (c)  Every Holder of Debt 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

                                                                              75

the source from which such information was derived, and that the Trustee shall
not be held accountable by reason of mailing of any material pursuant to a
request made under Section 7.02(b).

it acts as Trustee, in the manner hereinafter provided in this Section 7.03, a
brief report dated such date with respect to any of the following events which

     elects so to state, the circumstances surrounding the making thereof) made
     by the Trustee (as such) which remain unpaid on the date of such report,
     and for the reimbursement of which it claims or may claim a lien or charge,
     prior to that of the Debt Securities of such series, on any property or
     funds held or collected by it as Trustee, except that the Trustee shall not
     be required (but may elect) to report such advances if such advances so
     remaining unpaid aggregate not more than 1/2 of 1% of the principal amount
     of the Outstanding Debt Securities of such series on the date of such
     report;

          (4)  any change to the amount, interest rate and maturity date of all
     other indebtedness owing by the Company (or any other obligor on the Debt
     Securities of such series) to the Trustee in its individual capacity, on
     the date of such report, with a brief description of any property held as
     collateral security therefor, except an indebtedness based upon a creditor
     relationship arising in any manner described in Section 311(b)(2),(3),(4)

          (6)  any additional issue of Debt Securities which the Trustee has not
     previously reported; and

          (7)  any action taken by the Trustee in the performance of its duties
     hereunder which it has not previously reported and which in its opinion
     materially affects the Debt Securities of such series, except action in
     respect of a default, notice of which has been or is to be withheld by the
     Trustee in accordance with Section 6.02.

          (b)  The Trustee shall transmit by mail to all Holders of Debt
Securities of any series (whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 7.02 (a)) for
which it acts as the Trustee, as hereinafter provided, a brief report with
respect to the character and amount of any advances (and if the Trustee elects
so to state, the circumstances surrounding the making thereof) made by the
Trustee (as such) since the date of the last report transmitted pursuant to
subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a lien or charge, prior to that of
the Debt Securities of such series, on property or funds held or collected by it
as Trustee, and which it has not previously reported pursuant to this
subsection, except that the Trustee for each series shall not be required (but
may elect) to report such advances if such advances remaining unpaid at any time

     Exchange Act of 1934, as amended, in respect of a security listed and

     to time in such rules and regulations.

          Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or

such instrument or instruments. Whenever in this Indenture it is provided that
the Holders of a specified percentage in aggregate principal amount of the
Outstanding Debt Securities of any series may take any Act, the fact that the

the instrument or instruments executed by Holders in person or by agent or proxy
appointed in writing, or (b) by the record of Holders voting in favor thereof at
any meeting of such Holders duly called and held in accordance with the

          The ownership of Registered Securities of any series shall be proved
by the Security Register for such series or by a certificate of the Security
Registrar for such series.

          The ownership of Bearer Securities shall be proved by production of
such Bearer Securities or by a certificate executed by any bank or trust
company, which certificate shall be dated and shall state that on the date
thereof a Bearer Security bearing a specified identifying number or other mark
was deposited with or exhibited to the person executing such certificate by the
person named in such certificate, or by any other proof of possession reasonably
satisfactory to the Trustee. The holding by the Person named in any such
certificate of any Bearer Security specified therein shall be presumed to
continue for a period of one year unless at the time of determination of such
holding (1) another certificate bearing a later date issued in respect of the
same Bearer Security shall be produced to the Trustee, (2) such Bearer Security
shall be produced by some other Person to the Trustee, (3) such Bearer Security
shall have been registered on the Security Register, if, pursuant to Section
3.01, such Bearer Security can be so registered, or (4) such Bearer Security
shall have been cancelled or paid.

agent or proxy shall be sufficient and conclusive in favor of the Trustee and
the Company if made in the following manner:

          The fact and date of the execution by any such person of any
instrument may be proved by the certificate of any notary public or other
officer authorized to take acknowledgements of deeds, that the person executing
such instrument acknowledged to him the execution thereof, or by an affidavit of
a witness to such execution sworn to before any such notary or other such
officer. Where such execution is by an officer of a corporation or association
or a member of a partnership on behalf of such corporation, association or
partnership, as the case may be, or by any other Person acting in a
representative capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority.

          The record of any Holders' meeting shall be proved in the manner
provided in Section 9.06.

          The Trustee may in any instance require further proof with respect to
any of the matters referred to in this Section so long as the request is a
reasonable one.

          Section 8.03.  Persons Deemed Owners.
                         ---------------------

          The Company, the Trustee and any agent of the Company or the Trustee

thereof or on account thereof and for all other purposes whatsoever, whether or
not such Bearer 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. All payments made to any Holder, or upon his order, shall be

          Subject to the provisions of Section 10.02, nothing contained in this
Indenture or in any of the Debt Securities or Coupons shall prevent any
consolidation or merger of the Company with or into any other corporation or
corporations (whether or not affiliated with the Company), or successive
consolidations or mergers in which the Company or its successor or successors
shall be a party or parties, or shall prevent any sale or conveyance of all or
substantially all the property of the Company to any other corporation (whether
or not affiliated with the Company) authorized to acquire and operate the same;

provided, however, that the Company hereby covenants and agrees, that upon any
--------  -------
such consolidation, merger, sale or conveyance of or by the Company, other than
consolidation or merger in which the Company is the continuing corporation, the
due and punctual payment of the principal of and premium, if any, and interest
on all of the Debt Securities and Coupons, according to their tenor, and the due
and punctual performance and observance of all of the covenants and conditions
of this Indenture to be performed by the Company, shall be expressly assumed, by
supplemental indenture satisfactory in form to the Trustee, executed and
delivered to the Trustee by the corporation (if other than the Company) formed
by such consolidation, or into which the Company shall have been merged, or by
the corporation which shall have acquired such property.

Trustee and satisfactory in form to the Trustee, of the due and punctual payment

principal of and premium, if any, and interest on all of the Debt Securities and
Coupons and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Company, such successor
corporation shall succeed to and be substituted for the Company, with the same
effect as if it had been named herein as the party of the first part, and in the
event of any such sale or conveyance, the Company (which term shall for this
purpose mean the corporation named as the "Company" in the first paragraph of
this Indenture or any successor corporation which shall theretofore become such
in the manner described in Section 10.01) shall be discharged from all
obligations and covenants under this Indenture and the Debt Securities and
Coupons and may be dissolved and liquidated. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of Sunoco, Inc. any or all of the Debt Securities and Coupons issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee; and, upon the order of such successor corporation
instead of the Company and subject to all the terms, conditions and limitations
in this Indenture prescribed, the Trustee shall authenticate and shall deliver
any Debt Securities and Coupons which previously shall have been signed and
delivered by the officers of the Company to the Trustee for authentication, and
any Debt Securities and Coupons which such successor corporation thereafter
shall cause to be signed and delivered to the Trustee for that purpose. All the
Debt Securities and Coupons of any series so issued shall in all respects have
the same legal rank and benefit under this Indenture as the Debt Securities and
Coupons of such series theretofore or thereafter issued in accordance with the
terms of this Indenture as though all of such Debt Securities and Coupons had
been issued at the date of the execution hereof.

     In case of any consolidation or merger of the Company with or into any
other corporation, or upon any sale or conveyance of all or substantially all
the property of the Company to any other corporation, any of the property of the
Company or any Subsidiary would thereupon become subject to any mortgage, lien
or pledge which would not otherwise be permitted by this Indenture without
making effective provision for securing the Outstanding Debt Securities of any
series, the Company prior to or simultaneously with such consolidation, merger,
sale or conveyance, will secure such series of Outstanding Debt Securities
equally and ratably with any other obligations of the Company or any Subsidiary
then entitled thereto, by a direct lien on such property prior to all liens
other than any theretofore existing thereon.

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

an office or agency where Debt Securities of that series may be presented or
surrendered for payment, where Debt Securities of that series may be surrendered
for registration of transfer or exchange, where Debt Securities that are

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 Debt Securities of that series may be
surrendered for exchange, where Debt Securities of that series which are
convertible may be surrendered for conversion, where notices and demands to or

Coupons may be presented or surrendered for payment in the circumstances
described in the following paragraph (and not otherwise), (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Debt
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, if so provided pursuant to Section 3.01); provided, however,
                                                          --------  -------
that if the Debt Securities of that series are listed on The Stock Exchange of
the United Kingdom and the Republic of Ireland, 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 Debt
Securities of that series in London, Luxembourg or any other required city
located outside the United States, as the case may be, so long as the Debt
Securities of that series are listed on such exchange, and (C) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series

maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee (in the case
of Registered Securities) and at the place specified for the purpose pursuant to
Section 3.01 (in the case of Bearer Securities), and the Company hereby appoints
the Trustee as its agent to receive all presentations, surrenders, notices and
demands.

          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, that, if
                                                     --------  -------
the Debt Securities of a series are denominated and payable in Dollars, payment
of principal of and any premium and interest on any Bearer Security (including
any additional amounts payable on Securities of such series, if so provided
pursuant to Section 3.01) shall be made at the office of the Company's Paying
Agent in the Borough of Manhattan, The City and State of New York if (but only
if) payment in Dollars of the full amount of such principal, premium, interest
or additional amounts, as the case may be, at all offices or agencies outside
the United States maintained for the purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

          The Company may also from time to time designate different or
additional offices or agencies to be maintained for such purposes (in or outside
of such Place of Payment), and may from time to time rescind any such
designations; provided, however, that no such designation or rescission shall in
              --------  -------
any manner relieve the Company of its obligations described in the preceding
paragraph. The Company will give prompt written notice to the Trustee of any
such additional designation or rescission of designation and any change in the
location of any such different or additional office or agency.

Trust.
-----

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Debt Securities and Coupons, if any, it will, on or
before each due date of the principal of (and premium, if any) or interest on
any of the Debt Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal
(and premium, if any) 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 with respect
to any series of Debt Securities and Coupons, it will, by or on each due date
(but if payment is to be made outside the United States, at least one Business
Day before each due date) of the principal (and premium, if any) or interest on
any Debt Securities of such series, deposit with any such Paying Agent a sum
sufficient to pay the principal (and premium, if any) or interest so becoming
due, such sum to be held in trust for the benefit of the Persons entitled
thereto, and (unless any 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 with respect to any series of
Debt Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

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

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

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

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such 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 (and premium, if
any) or interest on any Debt Security of any series and remaining unclaimed for
two years

after such principal (and premium, if any) or interest has become due and
payable shall, unless otherwise required by applicable law, be paid to the
Company upon Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Debt Security or Coupon 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 transmitted in the manner and to the extent
provided by Section 1.05, 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 notification, any unclaimed balance of such money then remaining
will be repaid to the Company.

          If the Debt Securities of a series are listed on The Stock Exchange of
the United Kingdom and the Republic of Ireland and such stock exchange shall so
require, the Company will not purchase any Debt Securities of that series by
private treaty at a price (exclusive of expenses and accrued interest) which
exceeds 120% of the mean of the nominal quotations of the Debt Securities of
that series as shown in The Stock Exchange Daily Official List for the last
trading day preceding the date of purchase.

          Section 12.07.  Limitation on Liens.
                          -------------------

          Nothing in this Indenture or in the Debt Securities or Coupons, if
any, shall in any way restrict or prevent the Company or any Subsidiary from
incurring any indebtedness; provided that the Company covenants and agrees that
neither it nor any Restricted Domestic Subsidiary will issue, assume or
guarantee any notes, bonds, debentures or other similar evidences of
indebtedness for money borrowed (hereinafter in this Article Twelve called
"Debt") secured by mortgage, lien, pledge or other encumbrance upon any
Restricted Property without effectively providing that the Debt Securities of
all series (excluding any series of Debt Securities with respect to which the
property securing such Debt is not Restricted Property, but including, if the
Company so determines, any other indebtedness or obligation then existing and
any other indebtedness or obligation, thereafter created, ranking equally with
the Debt Securities of all series) shall be secured equally and ratably with (or
prior to) such Debt so long as such Debt shall be so secured, except that the
foregoing provisions shall not apply to:

          (a)  mortgages, liens, pledges or other encumbrances (hereinafter in
     this Article Twelve called "Mortgages") in existence on the date hereof
     and, with respect to any particular series of Debt Securities, any Mortgage
     existing at the date that Debt Securities of such series are first issued;

          (b)  Mortgages on property to secure all or part of the cost of
     exploration, drilling or development thereof or all or part of the cost of
     altering or repairing equipment used in connection therewith or (in case of
     property which is, in the opinion of the Board of Directors, substantially
     unimproved for the use intended by the Company) all or part of the cost of
     improvement thereof, or to secure Debt incurred to provide funds for any
     such purpose;

          (c)  Mortgages which secure only indebtedness owing by a Subsidiary to
     the Company, to one or more Subsidiaries or to the Company and one or more
     Subsidiaries;

          (d)  Mortgages on the property of any corporation existing at the time
     such corporation becomes a Subsidiary;

          (e)  Mortgages on any property to secure Debt or other indebtedness
     incurred in connection with the construction, installation or financing of
     pollution control or abatement facilities, other forms of industrial
     revenue bond financing or Debt issued or guaranteed by the United States,
     any State or any department, agency or instrumentality of either; or

          (f)  In the case of any series of Debt Securities, any extension,
     renewal or replacement (or successive extensions, renewals or
     replacements), in whole or in part, of any Mortgage existing at the date
     Debt Securities of such series are first issued, or any Mortgage referred
     to in the foregoing clauses (a) through (e) or of any Debt secured thereby,
     provided that the principal amount of Debt secured thereby shall not exceed
     the principal amount of Debt so secured at the time of such extension,
     renewal or replacement, and that such extension, renewal or replacement
     Mortgage shall be limited to all or part of substantially the same property
     which secured the Mortgage extended, renewed or replaced (plus improvements
     on such property).

          Notwithstanding the foregoing provisions of this Section 12.07, the
Company and any one or more Restricted Domestic Subsidiaries may issue, assume
or guarantee Debt secured by Mortgages which would otherwise be subject to the
foregoing restrictions in an aggregate principal amount which, together with the
aggregate outstanding principal amount of all other Debt of the Company and its
Restricted Domestic Subsidiaries which would otherwise be subject to the
foregoing restrictions (not including Debt permitted to the secured under
clauses (a) through (f)) and the aggregate Value of the Sale and Lease-Back
Transactions in existence at such time (not including Sale and Lease-Back
Transactions described in Section 12.08(a) or as to which the Company has
complied with Section 12.08(b)) does not at the time of issuance, assumption, or
guarantee thereof exceed 5%

surplus and net income retained for use in the business, after deducting the
costs of the shares of stock of the Company held in its treasury.

to create Debt secured by Mortgages:

          (1)  The sale or other transfer of crude oil, natural gas or other
     petroleum hydrocarbons in place for a period of time until, or in an amount
     such that, the transferee will realize therefrom a specified amount
     (however determined) of money or such crude oil, natural gas or other
     petroleum hydrocarbons, or the sale or other transfer of any other interest
     in property of the character commonly referred to as a production payment
     or as an overriding royalty, and

          (2)  Mortgages required by any contract or statute in order to permit
     the Company or a Subsidiary to perform any contract or subcontract made by
     it with or at the request of the United States, and State or any
     department, agency or instrumentality of either, or to secure partial,
     progress, advance or any other payments to the Company or any Subsidiary by
     the United States, any State or any department, agency or instrumentality
     of either pursuant to the provisions of any contract or statute.

          Section 12.08.  Limitation on Sale and Lease-Back Transactions.
                          ----------------------------------------------

          The Company covenants and agrees that neither it nor any Restricted
Domestic Subsidiary will enter into any arrangement with any Person, or to which
any Person is a party, providing for the leasing to the Company or a Restricted
Domestic Subsidiary for a period of more than three years of any Restricted
Property which has been or is to be sold or transferred by the Company or such
Restricted Domestic Subsidiary to such Person or to any other Person to which
funds have been or are to be advanced by such Person on the security of the
leased property (in this Article Twelve called "Sale and Lease-Back
Transaction") unless either:

          (a)  the Company or such Restricted Domestic Subsidiary would be
     entitled, pursuant to the provisions of Section 12.07, to incur Debt in a
     principal amount equal to or exceeding the Value of such Sale and Lease-
     Back Transaction, secured by Mortgage on the property to be leased, without
<PAGE>

     equally and ratably securing all series of Debt Securities with respect
     to which such property is Restricted Property, or

          (b)  the Company (and in any such case the Company covenants and
     agrees that it will do so) during or immediately after the expiration of
     four months after the effective date of such Sale and Lease-Back
     Transaction (whether made by the Company or a Restricted Domestic
     Subsidiary) applies to the voluntary retirement of Funded Debt of the
     Company (including Debt Securities) an amount equal to the Value of such
     Sale and Lease-Back Transaction, less the principal amount of Debt
     Securities delivered, within four months after the effective date of such
     arrangement, to the Trustee for retirement and cancellation and the
     principal amount of other Funded Debt voluntarily retired by the Company
     within such four month period, excluding retirements of Debt Securities and
     other Funded Debt as a result of conversions or pursuant to mandatory
     sinking fund or mandatory prepayment provisions or by payment at maturity.

          For purposes of Section 12.07 and this Section 12.08, the term "Value"
shall mean, with respect to a Sale and Lease-Back Transaction, as of any
particular time, the amount equal to the greater of (1) the net proceeds of the
sale or transfer of the property leased pursuant to such Sale and Lease-Back
Transaction or (2) the fair value in the opinion of the Board of Directors of
such property at the time of entering into such Sale and Lease-Back Transaction,
in either case divided first by the number of full years of the term of the
lease and then multiplied by the number of full years of such term remaining at
the time of determination, without regard to any renewal or extension options
contained in the lease.

herein and specified pursuant to Section 3.01 to be applicable to the Securities
of any series, except as otherwise provided pursuant to Section 3.01) with
respect to the Debt Securities of any series if before the time for such
compliance the Holders of at least a majority in principal amount of the
Outstanding Debt Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent expressly so waived, and,
until

                         REDEMPTION OF DEBT SECURITIES

          Section 13.01.  Applicability of Article.
                          ------------------------

          Debt Securities of any series which are redeemable before their
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified pursuant to Section 3.01 for Debt Securities of any series)
in accordance with this Article.

          Section 13.02.  Election to Redeem; Notice to Trustee.
                          -------------------------------------

          In case of any redemption at the election of the Company, the Company
shall, at least 60 days before the Redemption Date fixed by the Company (unless
a shorter notice shall be satisfactory to the Trustee), notify the Trustee of
such Redemption Date and of the principal amount of Debt Securities of such
series to be redeemed. In the case of any redemption of Debt Securities prior to
the expiration of any restriction on such redemption provided in the terms of
such Debt Securities or elsewhere in this Indenture, the Company shall furnish
the Trustee with an Officers' Certificate evidencing compliance with such
restrictions.

          Section 13.03.  Selection by Trustee of Debt Securities to Be
                          ---------------------------------------------
Redeemed.
--------

          Except in the case of a redemption in whole of the Bearer Securities
or the Registered Securities of such series, if less than all the Debt
Securities of any series are to be redeemed at the election of the Company, the
particular Debt Securities to be redeemed shall be selected not more than 60
days prior to the Redemption Date by the Trustee, from the Outstanding Debt
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum authorized
denomination for Debt Securities of such series or any integral multiple
thereof) of the principal amount of Debt Securities of such series in a
denomination larger than the minimum authorized
<PAGE>

                                                                              98

denomination for Debt Securities of such series pursuant to Section 3.02 in the
Currency in which the Debt Securities of such series are denominated. The
portions of the principal amount of Debt Securities so selected for partial
redemption shall be equal to the minimum authorized denominations for Debt
Securities of such series pursuant to Section 3.02 in the Currency in which the
Debt Securities of such series are denominated or any integral multiple thereof,
except as otherwise set forth in the applicable form of Debt Securities. In any
case when more than one Registered Security of such series is registered in the
same name, the Trustee in its discretion may treat the aggregate principal
amount so registered as if it were represented by one Registered Security of
such series.

          If any Debt Security selected for partial redemption is converted in
part before termination of the conversion right with respect to the portion of
the Debt Security so selected, the converted portion of such Debt Security shall
be deemed (so far as may be) to be the portion selected for redemption. Debt
Securities which have been converted during a selection of Debt Securities to be
redeemed shall be treated by the Trustee as Outstanding for the purpose of such
selection.

          The Trustee shall promptly notify the Company in writing of the Debt
Securities selected for redemption and, in the case of any Debt Securities
selected for partial redemption, the principal amount thereof to be redeemed.

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

          Section 13.04.  Notice of Redemption.
                          --------------------

          Notice of redemption shall be given by the Company, or at the
Company's request, by the Trustee in the name and at the expense of the Company,
not less than 30 days and not more than 60 days prior to the Redemption Date to
the Holders of Debt Securities of any series to be redeemed in whole or in part
pursuant to this Article Thirteen, in the manner provided in Section 1.05. Any
notice so given shall be conclusively presumed to have been duly given, whether
or not the Holder receives such notice. Failure to give such notice, or any
defect in such notice to the Holder of any Debt Security of a series designated
for redemption, in whole or in part, shall not affect the sufficiency of any
notice of redemption with respect to the Holder of any other Debt Security of
such series.

          All notices of redemption shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price,

     Company pursuant to provisions contained in this Indenture or the terms of
     the Debt Securities of such series or a supplemental indenture establishing
     such series, if such be the case, together with a brief statement of the
     facts permitting such redemption,

          (4)  if less than all Outstanding Debt Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Debt Securities to be redeemed,

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

          (6)  in the case of Debt Securities of any series that is convertible,
     the conversion price, the date on which the right to convert the principal
     of the Debt Securities of such series to be redeemed will terminate and the
     place or places where such Debt Securities may be surrendered for
     conversion,

          (7)  that, unless otherwise specified in such notice, Coupon
     Securities of any series, if any, surrendered for redemption must be
     accompanied by all Coupons maturing subsequent to the date fixed for
     redemption, failing which the amount of any such missing Coupon or Coupons
     will be deducted from the Redemption Price,

          (8)  the Place or Places of Payment where such Debt Securities are to
     be surrendered for payment of the Redemption Price,

          (9)  if Bearer Securities of any series are to be redeemed and any
     Registered Securities of such series are not to be redeemed, and if such
     Bearer Securities may be exchanged for Registered Securities not subject to
     redemption on this Redemption Date pursuant to Section 3.05(b) or
     otherwise, the last date on which such exchanges may be made,

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

          Section 13.05.  Deposit of Redemption Price.
                          ---------------------------

          On or prior to (but, if payment is to be made outside the United
States, at least One Business Day prior to) the Redemption Date for any Debt
Securities, the Company shall deposit with the Trustee or with a Paying Agent
(or, if the Company is acting as its own Paying Agent, segregate and hold in
trust as provided in Section 12.04) an amount of money in the Currency or
Currencies in which such Debt Securities are denominated (except as provided
pursuant to Section 3.01) sufficient to pay the Redemption Price of such Debt
Securities or any portions thereof which are to be redeemed on that date.

          Section 13.06.  Debt Securities Payable on Redemption Date.
                          ------------------------------------------

          Notice of redemption having been given as aforesaid, any Debt
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price in the Currency in which the Debt Securities of
such series are payable (except as otherwise specified pursuant to Section 3.01
or 3.10), and from and after such date (unless the Company shall default in the
payment of the Redemption Price) such Debt 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 Debt Security for redemption in accordance with
said notice, such Debt Security 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 (except as
otherwise provided in Section 12.03) and, unless otherwise specified as
contemplated by Section 3.01, only upon presentation and surrender of Coupons
for such interest; and provided, further, that, unless otherwise specified as
                       --------  -------
contemplated by Section 3.01, installments of interest on Registered Securities
which have a Stated Maturity on or prior to the Redemption Date for such Debt
Securities shall be payable according to the terms of such Debt Securities and
the provisions of Section 3.07.

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

          If any Coupon Security surrendered for redemption shall not be
accompanied by all Coupons appertaining thereto maturing on or after the
Redemption Date, the Redemption Price for such Coupon Security may be reduced by
an amount equal to the face amount of all such missing Coupons. If thereafter
the Holder of such Coupon shall surrender to any Paying Agent outside the United
States any such missing Coupon in respect of which a
<PAGE>

                                                                             101

deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted. 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.

          Section 13.07.  Debt Securities Redeemed in Part.
                          --------------------------------

          Any Debt Security which is to be redeemed only in part shall be
surrendered at the Corporate Trust Office or such other office or agency of the
Company as is specified pursuant to Section 3.01 (in the case of Registered
Securities) and at an office of the Trustee or such other office or agency of
the Company outside the United States as is specified pursuant to Section 3.01
(in the case of Bearer Securities) with, if the Company, the Security Registrar
or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company, the Security Registrar and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing, and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Debt Security without service charge, a new Debt
Security or Debt Securities of the same series, of like tenor and form, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Debt Security so surrendered, and, in the case of a Coupon Security, with
appropriate Coupons attached. In the case of a Debt Security providing
appropriate space for such notation, at the option of the Holder thereof, the
Trustee, in lieu of delivering a new Debt Security or Debt Securities as
aforesaid, may make a notation on such Debt Security of the payment of the
redeemed portion thereof.

          Section 14.01.  Applicability of Article.
                          ------------------------

          The provisions of this Article shall be applicable to any sinking fund
for the retirement of Debt Securities of a series except as otherwise specified
pursuant to Section 3.01 for Debt Securities of such series.

          The minimum amount of any sinking fund payment provided for by the
terms of Debt 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 Debt Securities of any series is herein referred to as an
"optional sinking fund payment". If provided for by the terms

                                                                             102

of Debt Securities of any series, the amount of any cash sinking fund payment
may be subject to reduction as provided in Section 14.02. Each sinking fund
payment shall be applied to the redemption of Debt Securities of any series as
provided for by the terms of Debt Securities of such series.

                          ----------------------------------------------------
Debt Securities.
---------------

          In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Debt Securities of a series in cash, the Company may at its
option, deliver to the Trustee Debt Securities of such series (together with the
unmatured Coupons, if any, appertaining thereto) theretofore purchased or
otherwise acquired by the Company, except Debt Securities of such series which
have been redeemed through the application of mandatory sinking fund payments
pursuant to the terms of the Debt Securities of such series, accompanied by a
Company Order instructing the Trustee to credit such obligations and stating
that the Debt Securities of such series were originally issued by the Company by
way of bona fide sale or other negotiation for value, provided that such Debt
                                                      --------
Securities shall not have been previously so credited. Such Debt Securities
shall be received and credited for such purpose by the Trustee at the Redemption
Price specified in such Debt Securities for redemption through operation of the
sinking fund and the amount of such mandatory sinking fund payment shall be
reduced accordingly.

          Section 14.03.  Redemption of Debt Securities for Sinking Fund.
                          ----------------------------------------------

          Not less than 60 days prior to each sinking fund payment date for any
series of Debt Securities (unless a shorter period shall be satisfactory to the
Trustee), the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the Currency or Currencies in which the Debt
Securities of such series are denominated (except as provided pursuant to
Section 3.01) and the portion thereof, if any, which is to be satisfied by
delivering and crediting Debt Securities of such series pursuant to Section
14.02 and shall also deliver to the Trustee any Debt Securities to be so
delivered. In the case of the failure of the Company to deliver such
certificate, the sinking fund payment due on the next succeeding sinking fund
payment date for such series shall be paid entirely in cash and shall be
sufficient to redeem the principal amount of the Debt Securities of such series
subject to a mandatory sinking fund payment without the right to deliver or
credit Debt Securities as provided in Section 14.02 and without

                                                                             103

the right to make any optional sinking fund payment with respect to such series
at such time.

          Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Debt Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Debt
Securities of such series at the Redemption Price specified in such Debt
Securities with respect to the sinking fund. Any sinking fund moneys not so
applied or allocated by the Trustee (or by the Company if the Company is acting
as its own Paying Agent) to the redemption of Debt Securities shall be added to
the next sinking fund payment received by the Trustee (or if the Company is
acting as its own Paying Agent, segregated and held in trust as provided in
Section 12.04) for such series and, together with such payment (or such amount
so segregated) shall be applied in accordance with the provisions of this
Section. Any and all sinking fund moneys with respect to the Debt Securities of
any particular series held by the Trustee (or if the Company is acting as its
own Paying Agent, segregated and held in trust as provided in Section 12.04) on
the last sinking fund payment date with respect to Debt Securities of such
series and not held for the payment or redemption of particular Debt Securities
of such series shall be applied by the Trustee (or by the Company if the Company
is acting as its own Paying Agent), together with other moneys, if necessary, to
be deposited (or segregated) sufficient for the purpose, to the payment of the
principal of the Debt Securities of such series at Maturity.

          The Trustee shall select or cause to be selected the Debt Securities
to be redeemed upon such sinking fund payment date in the manner specified in
Section 13.03 and the Company shall cause notice of the redemption thereof to be
given in the manner provided in Section 13.04. Such notice having been duly
given, the redemption of such Debt Securities shall be made upon the terms and
in the manner stated in Section 13.06.

          On or before (but, if payment is to be made outside the United States,
at least one Business Day prior to) each sinking fund payment date, the Company
shall pay to the Trustee (or, if the Company is acting as its own Paying Agent,
the Company shall segregate and hold in trust as provided in Section 12.04) in
cash a sum, in the Currency or Currencies in which Debt Securities of such
series are denominated (except as provided pursuant to Sections 3.01 or 3.10),
equal to the principal and any interest accrued to the Redemption Date for Debt
Securities or portions

thereof to be redeemed on such sinking fund payment date pursuant to this
Section.

          Neither the Trustee nor the Company shall redeem any Debt Securities
of a series with sinking fund moneys or mail any notice of redemption of Debt
Securities of such series by operation of the sinking fund for such series
during the continuance of a default in payment of interest, if any, on any Debt
Securities of such series or of any Event of Default (other than an Event of
Default occurring as a consequence of this paragraph) with respect to the Debt
Securities of such series, except that if the notice of redemption shall have
been provided in accordance with the provisions hereof, the Trustee (or the
Company, if the Company is then acting as its own Paying Agent) shall redeem
such Debt Securities if cash sufficient for that purpose shall be deposited with
the Trustee (or segregated by the Company) for that purpose in accordance with
the terms of this Article. Except as aforesaid, any moneys in the sinking fund
for such series at the time when any such default or Event of Default shall
occur and any moneys thereafter paid into such sinking fund shall, during the
continuance of such default or Event of Default, be held as security for the
payment of the Debt Securities and Coupons, if any, of such series; provided,
                                                                    --------
however, that in case such default or Event of Default shall have been cured or

waived as provided herein, such moneys shall thereafter be applied on or prior
to the next sinking fund payment date for the Debt Securities of such series on
which such moneys may be applied pursuant to the provisions of this Section.

Debt Securities of a series, and if the Debt Securities of such series are
Registered Securities and denominated and payable only in Dollars (except as
provided pursuant to Section 3.01) then the provisions of this Article shall be

option") or (b) the Company shall cease to be under any obligation to comply
with any term, provision or condition set forth in Sections 10.01, 10.02, 12.07
and 12.08 with respect to Debt Securities of any series (and, if so specified
pursuant to Section 3.01, any other obligation of the Company or restrictive
covenant added for the benefit of such series pursuant to Section 3.01)
("covenant defeasance option") at any time after the applicable conditions set
forth below have been satisfied:

          (1)  the Company shall have deposited or caused to be deposited
     irrevocably with the Trustee as trust funds in trust, specifically pledged
     as security for, and dedicated solely to, the benefit of the Holders of the
     Debt Securities of such series (i) money in an amount, or (ii) U.S.
     Government Obligations (as defined below) which through the payment of
     interest and principal in respect thereof in accordance with their terms
     will provide, not later than one day before the due date of any payment,
     money in an amount, or (iii) a combination of (i) and (ii), sufficient, in
     the opinion (with respect to (i) and (ii)) of a nationally recognized firm
     of independent public accountants expressed in a written certification
     thereof delivered to the Trustee, to pay and discharge each installment of
     principal (including any mandatory sinking fund payments) of and premium,
     if any, and interest on, the Outstanding Debt Securities of such series on
     the dates such installments of interest, principal, and premium are due;

          (2)  such deposit shall not cause the Trustee with respect to the Debt
     Securities of that series to have a conflicting interest as defined in the
     Trust Indenture Act with respect to the Debt Securities of any series;

          (3)  such deposit will not result in a breach or violation of, or
     constitute a default under, this Indenture or any other agreement or
     instrument to which the Company is a party or by which it is bound;

          (4)  if the Debt Securities of such series are then listed on any
     national securities exchange, the Company shall have delivered to the
     Trustee an Opinion of Counsel or a letter or other document from such
     exchange to the effect that the Company's exercise of its option under this
     Section would not cause such Debt Securities to be delisted;

          (5)  no Event of Default or event (including such deposit) which, with
     notice or lapse of time or both, would become an Event of Default with
     respect to the Debt Securities of such series shall have occurred and be

     or Section 5.01(6) or event which with the giving of notice or lapse of
     time, or both, would become an Event of Default under Section 5.01(5) or
     Section 5.01(6) shall have occurred and be continuing on the 91st day after
     such date; and

          (6)  the Company shall have delivered to the Trustee an Opinion of
     Counsel or a ruling from the Internal Revenue Service to the effect that
     the Holders of the Debt Securities of such series will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     deposit, defeasance or Discharge.

Notwithstanding the foregoing, if the Company exercises its covenant defeasance
option and an Event of Default under Section 5.01(5) or Section 5.01(6) or event
which with the giving of notice or lapse of time, or both, would become an Event
of Default under Section 5.01(5) or Section 5.01(6) shall have occurred and be
continuing on the 91st day after the date of such deposit, the obligations of
the Company referred to under the definition of covenant defeasance option with
respect to such Debt Securities shall be reinstated.

          "Discharged" means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by, and obligations under, the
Debt Securities of such series and to have satisfied all the obligations under
this Indenture relating to the Debt Securities of such series (and the Trustee,
at the expense of the Company, shall execute proper instruments acknowledging
the same), except (A) the rights of Holders of Debt Securities of such series to
receive, from the trust fund described in clause (1) above, payment of the
principal of (and premium, if any) and interest on such Debt Securities when
such payments are due, (B) the Company's obligations with respect to the Debt
Securities of such series under Sections 3.04, 3.05, 3.06, 12.03 and 15.03 and
(C) the rights, powers, trusts, duties and immunities of the Trustee hereunder.

          "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States for the payment of which its full faith and
credit is pledged, or (ii) obligations of a Person controlled or supervised by
and acting as an agency or instrumentality of the United States the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States, which, in either case under clauses (i) or (ii), are not callable
or redeemable at the option of the issuer thereof, and shall also include a
depository receipt issued by a bank or trust company as custodian with respect
to any such U.S. Government Obligation or a specific payment of interest on or
principal of any such U.S. Government obligation held by such custodian for the

held in trust and applied by it, in accordance with the provisions of such Debt
Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of such Debt Securities, of all sums due

          Section 16.01.  Applicability; Conversion Privilege.
                          -----------------------------------

          Except as otherwise specified pursuant to Section 3.01 for Debt
Securities of any series, the provisions of this Article Sixteen shall be
applicable to any Debt Securities that are convertible into Equity Securities.
Each reference in this Article to a "Debt Security" or "Debt Securities" refers
to the Debt Securities of a particular series that is convertible into Equity
Securities, and references to a "Coupon" or "Coupons"
<PAGE>

                                                                             108

refer to the Coupons appertaining to the Debt Securities of such series. Without
limiting the generality of the immediately preceding sentence, if two or more
series of Debt Securities with conversion privileges are outstanding at any
time, (i) the provisions of this Article shall be applied separately to each
such series, and (ii) references to the Trustee refer to the Trustee for the
Debt Securities of such series. If so provided pursuant to Section 3.01 with
respect to the Debt Securities of any series, the Holder of a Debt Security of
such series shall have the right, at such Holder's option, to convert, in
accordance with the terms of such series of Debt Securities and this Article
Sixteen, all or any part (if the portion to be converted and the remaining
portion of such Debt Security are in authorized denominations for that series of
Debt Securities) of such Debt Security into shares of Equity Securities, at any
time during the period specified in the terms of the Debt Securities of that
series pursuant to Section 3.01, at the Conversion Price in effect on the date
of conversion, or, as to any Debt Securities called for redemption, at any time
prior to the time and date fixed for such redemption (unless the Company shall
default in the payment of the Redemption Price, in which case such right shall
not terminate at such time and date).

          Section 16.02.  Conversion Procedure; Conversion Price; Fractional
                          --------------------------------------------------
Shares.
------

          (a)  Except as otherwise specified as contemplated by Section 3.01 for
Debt Securities of any series, each Debt Security of such series to which this
Article is applicable shall be convertible at the office of the Conversion
Agent, and at such other place or places, if any, specified pursuant to Section
3.01 with respect to the Debt Securities of such series, into fully paid and
nonassessable shares (calculated to the nearest 1/100th of a share) of Equity
Securities. The Debt Securities will be converted into shares of Equity
Securities at the Conversion Price therefor. No payment or adjustment shall be
made in respect of dividends on the Equity Securities or accrued interest on a
converted Debt Security except as described in Section 16.09 and Section
16.02(c). The Company may, but shall not be required, in connection with any
conversion of Debt Securities, to issue a fraction of a share of any Equity
Security and, if the Company shall determine not to issue any such fraction, the
Company shall, subject to Section 16.03(4), make a cash payment (calculated to
the nearest cent) equal to such fraction multiplied by the Closing Price of such
Equity Security on the last Trading Day prior to the date of conversion.

          (b)  Before any Holder of a Debt Security shall be entitled to convert
the same into Equity Securities, such Holder shall surrender such Debt Security
duly endorsed to the Company or in blank, or, in the case of Bearer Securities,
together with all unmatured Coupons and any matured Coupons in default attached
<PAGE>

                                                                             109

thereto, at the office of the Conversion Agent or at such other place or places,
if any, specified pursuant to Section 3.01 (in the case of Registered
Securities) and at an office of the Conversion Agent or at such other place or
places, if any, outside of the United States as is specified pursuant to Section
3.01 (in the case of Bearer Securities), and shall give written notice to the
Company at said office or place that he elects to convert the same and shall
state in writing therein the principal amount of Debt Securities to be converted
and the name or names (with addresses) in which he wishes the certificate or
certificates for Equity Securities to be issued.

          If more than one Debt Security shall be surrendered for conversion at
one time by the same Holder, the number of full shares of Equity Securities
which shall be deliverable upon conversion shall be computed on the basis of the
aggregate principal amount of the Debt Securities (or specified portions thereof
to the extent permitted thereby) so surrendered. Subject to the next succeeding
sentence, the Company will, as soon as practicable after the surrender of a Debt
Security for conversion, issue and deliver at said office or place to the Holder
of a Debt Security or to his nominee or nominees, certificates for the number of
full shares of Equity Securities to which he shall be entitled as aforesaid,
together, subject to the last sentence of paragraph (a) above, with cash in lieu
of any fraction of a share to which he would otherwise be entitled. The Company
shall not be required to deliver certificates for shares of Equity Securities
while the stock transfer books for such stock or the Security Register are duly
closed for any purpose, but certificates for shares of Equity Securities shall
be issued and delivered as soon as practicable after the opening of such books
or Security Register.

          (c)  If, at the time of surrender pursuant to Section 16.02(a), the
Holder of a Bearer security is unable to produce all unmatured Coupon or Coupons
or matured Coupon or Coupons in default, such conversion may be effected if the
Bearer Securities to be surrendered for conversion are accompanied by payment in
funds acceptable to the Company in an amount equal to the face amount of such
missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons
may be waived by the Company and the Trustee if there is furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless. If thereafter the Holder of such Bearer Security shall surrender
to any Paying Agent any such missing Coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of
such payment; provided, however, that except as otherwise provided in Section
              --------  -------
12.03, interest represented by Coupons shall be payable only upon presentation
and surrender of those Coupons at an office or agency located outside the United
States.

          (d)  A Debt Security shall be deemed to have been converted as of the
close of business on the date of the surrender of such Debt Security for
conversion as provided above, and the Person or Persons entitled to receive the
Equity Securities issuable upon such conversion shall be treated for all
purposes as the record Holder or Holders of such Equity Securities as of the
close of business on such date.

          (e)  In case any Debt Security shall be surrendered for partial
conversion, the Company shall execute and the Trustee shall authenticate and
deliver to or upon the written order of the Holder of the Debt Securities so
surrendered, without charge to such Holder (subject to the provisions of Section
16.08), a new Debt Security or Securities in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the surrendered
Debt Security, together, in the case of Bearer Securities, with any unmatured
Coupons and matured Coupons in default attached thereto.

          Section 16.03.  Adjustment of Conversion Price for Equity Securities.
                          ----------------------------------------------------

          The Conversion Price with respect to any Debt Security which is
convertible into Equity Securities shall be adjusted from time to time as
follows:

          (1)  In case the Company shall, at any time or from time to time while
     any of such Debt Securities are outstanding, (i) pay a dividend in shares
     of an Equity Security to holders of such class of Equity Security, (ii)
     combine its outstanding shares of an Equity Security into a smaller number
     of shares of that Equity Security, (iii) subdivide its outstanding shares
     of an Equity Security into a greater number of shares of that Equity
     Security or (iv) make a distribution in shares of an Equity Security to
     holders of such Equity Security, then the Conversion Price in effect
     immediately before such action shall be adjusted so that the Holders of
     such Debt Securities, upon conversion thereof into Equity Securities
     immediately following such event, shall be entitled to receive the kind and
     amount of shares of capital stock of the Company which they would have
     owned or been entitled to receive upon or by reason of such event if such
     Debt Securities had been converted immediately before the record date (or,
     if no record date, the effective date) for such event. An adjustment made
     pursuant to this Section 16.03(1) shall become effective retroactively
     immediately after the record date in the case of a dividend or distribution
     and shall become effective retroactively immediately after the effective
     date in the case of a subdivision or combination. For the purposes of this
     Section 16.03(1), each Holder of Debt Securities shall be deemed to have
     failed to exercise any right to elect the
<PAGE>

                                                                             111

     kind or amount of securities receivable upon the payment of any such
     dividend, subdivision, combination or distribution (provided that if the
     kind or amount of securities receivable upon such dividend, subdivision,
     combination or distribution is not the same for each nonelecting share,
     then the kind and amount of securities or other property receivable upon
     such dividend, subdivision, combination or distribution for each
     nonelecting share shall be deemed to be the kind and amount so receivable
     per share by a plurality of the nonelecting shares).

          (2)  In case the Company shall, at any time or from time to time while
     any of such Debt Securities are Outstanding, issue rights or warrants to
     all or substantially all holders of shares of a class of its Equity
     Securities into which Debt Securities are convertible entitling them (for a
     period expiring within 45 days after the record date for such issuance) to
     subscribe for or purchase shares of such Equity Security (or securities
     convertible into shares of such Equity Security) at a price per share less
     than the Current Market Price of the Equity Security at such record date
     (treating the price per share of the securities convertible into such
     Equity Security as equal to (x) the sum of (i) the price for a unit of the
     security convertible into such Equity Security and (ii) any additional
     consideration initially payable upon the conversion of such security into
     such Equity Security divided by (y) the number of shares of such Equity
     Security initially underlying such convertible security), the Conversion
     Price with respect to such Debt Securities shall be adjusted, so that it
     shall equal the price determined by dividing the Conversion Price in effect
     immediately prior to the date of issuance of such rights or warrants by a
     fraction, the numerator of which shall be the number of shares of such
     Equity Security outstanding on the date of issuance of such rights or
     warrants plus the number of additional shares of such Equity Security
     offered for subscription or purchase (or into which the convertible
     securities so offered are initially convertible), and the denominator of
     which shall be the number of shares of such Equity Security outstanding on
     the date of issuance of such rights or warrants plus the number of shares
     or securities which the aggregate offering price of the total number of
     shares or securities so offered for subscription or purchase (or the
     aggregate purchase price of the convertible securities so offered plus the
     aggregate amount of any additional consideration initially payable upon
     conversion of such securities into such Equity Security) would purchase at
     such Current Market Price of such Equity Security. Such adjustment shall
     become effective retroactively immediately after the record date for the
     determination of stockholders entitled to receive such rights or warrants.
<PAGE>

                                                                             112

          (3)  In case the Company shall, at any time or from time to time while
     any of such Debt Securities are outstanding, distribute to all or
     substantially all holders of shares of a class of its Equity Securities
     into which Debt Securities are convertible (including any such distribution
     made in connection with a consolidation or merger in which the Company is
     the continuing corporation and such Equity Security is not changed or
     exchanged) cash, evidences of its indebtedness, securities or assets
     (excluding (i) regular periodic cash dividends in amounts, if any,
     determined from time to time by the Board of Directors (to the extent paid
     from current or retained earnings of the Company) or (ii) dividends payable
     in shares of such Equity Security for which adjustment is made under
     Section 16.03(1)) or rights or warrants to subscribe for or purchase
     securities of the Company (excluding those referred to in Section
     16.03(2)), then in each such case the Conversion Price with respect to such
     Debt Securities shall be adjusted so that it shall equal the price
     determined by dividing the Conversion Price in effect immediately prior to
     the date of such distribution by a fraction, the numerator of which shall
     be the Current Market Price of such Equity Security on the record date
     referred to below, and the denominator of which shall be such Current
     Market Price of such Equity Security less the then fair market value (as
     determined by the Board of Directors of the Company, whose determination
     shall be conclusive) of the portion of the cash or assets or evidences of
     indebtedness or securities so distributed or of such subscription rights or
     warrants applicable to one share of such Equity Security (provided that
     such denominator shall never be less than 1.0); provided, however, that no
                                                     --------  -------
     adjustment shall be made with respect to any distribution of rights to
     purchase securities of the Company if a Holder of Debt Securities would
     otherwise be entitled to receive such rights upon conversion at any time of
     such Debt Securities into such Equity Security unless such rights are
     subsequently redeemed by the Company, in which case such redemption shall
     be treated for purposes of this section as a dividend on such Equity
     Security. Such adjustment shall become effective retroactively immediately
     after the record date for the determination of stockholders entitled to
     receive such distribution; and in the event that such distribution is not
     so made, the Conversion Price shall again be adjusted to the Conversion
     Price which would then be in effect if such record date had not been fixed.

          (4)  The Company shall be entitled to make such additional adjustments
     in the Conversion Price, in addition to those required by subsections
     16.03(1), 16.03(2) and 16.03(3), as shall be necessary in order that any
     dividend or distribution of an Equity Security, any subdivision,
     reclassification or combination of shares of an Equity
<PAGE>

                                                                             113

     Security or any issuance of rights or warrants referred to above shall not
     be taxable to the holders of a class of an Equity Security for United
     States Federal income tax purposes.

          (5)  In any case in which this Section 16.03 shall require that any
     adjustment be made effective as of or retroactively immediately following a
     record date, the Company may elect to defer (but only for five (5) Trading
     Days following the filing of the statement referred to in Section 16.05)
     issuing to the Holder of any Debt Securities converted after such record
     date the shares of the Equity Security and other capital stock of the
     Company issuable upon such conversion over and above the shares of Equity
     Security and other capital stock of the Company issuable upon such
     conversion on the basis of the Conversion Price prior to adjustment;
     provided, however, that the Company shall deliver to such Holder a due bill
     --------  -------
     or other appropriate instrument evidencing such Holder's right to receive
     such additional shares upon the occurrence of the event requiring such
     adjustment.

          (6)  All calculations under this Section 16.03 shall be made to the
     nearest cent or one-hundredth of a share or security, with one-half cent
     and 0.005 of a share, respectively, being rounded upward. Notwithstanding
     any other provision of this Section 16.03, the Company shall not be
     required to make any adjustment of the Conversion Price unless such
     adjustment would require an increase or decrease of at least 1% of such
     price. Any lesser adjustment shall be carried forward and shall be made at
     the time of and together with the next subsequent adjustment which,
     together with any adjustment or adjustments so carried forward, shall
     amount to an increase or decrease of at least 1% in such price. Any
     adjustments under this Section 16.03 shall be made successively whenever an
     event requiring such an adjustment occurs.

          (7)  In the event that at any time, as a result of an adjustment made
     pursuant to this Section 16.03, the Holder of any Debt Security thereafter
     surrendered for conversion shall become entitled to receive any shares of
     stock of the Company other than shares of an Equity Security into which the
     Debt Securities originally were convertible, the Conversion Price of such
     other shares so receivable upon conversion of any such Debt Security shall
     be subject to adjustment from time to time in a manner and on terms as
     nearly equivalent as practicable to the provisions with respect to an
     Equity Security contained in subparagraphs (1) through (6) of this Section
     16.03, and the provision of Sections 16.01, 16.02 and 16.04 through 16.09
     with respect to the Equity Securities shall apply on like or similar
<PAGE>

                                                                             114

     terms to any such other shares and the determination of the Board of
     Directors as to any such adjustment shall be conclusive.

          (8)  No adjustment shall be made pursuant to this Section: (i) if the
     effect thereof would be to reduce the Conversion Price below the par value
     (if any) of the Common Stock or the stated value of the Preference Stock or
     (ii) subject to 16.03(5) hereof, with respect to any Debt Security that is
     converted prior to the time such adjustment otherwise would be made.

          Section 16.04. Consolidation or Merger of the Company.
                         --------------------------------------

          In case of either (a) any consolidation or merger to which the Company
is a party, other than a merger or consolidation in which the Company is the
surviving or continuing corporation and which does not result in a
reclassification of, or change (other than a change in par value or from par
value to no par value or from no par value to par value) in, outstanding shares
of an Equity Security or (b) any sale or conveyance of all or substantially all
of the property and assets of the Company to another Person, then each Debt
Security then outstanding shall be convertible from and after such merger,
consolidation, sale or conveyance of property and assets into the kind and
amount of shares of stock or other securities and property receivable upon such
consolidation, merger, sale or conveyance by a holder of the number of shares of
Equity Securities into which such Debt Securities would have been converted
immediately prior to such consolidation, merger, sale or conveyance, subject to
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article Sixteen (and assuming such holder of
the Equity Security failed to exercise his rights of election, if any, as to the
kind or amount of securities, cash or other property receivable upon such
consolidation, merger, sale or conveyance (provided that, if the kind or amount
of securities, cash or other property receivable upon such consolidation,
merger, sale or conveyance is not the same for each nonelecting share, then the
kind and amount of securities, cash or other property (including cash)
receivable upon such consolidation, merger, sale or conveyance for each
nonelecting share shall be deemed to be the kind and amount so receivable per
share by a plurality of the nonelecting shares or securities)). The Company
shall not enter into any of the transactions referred to in clause (a) or (b) of
the preceding sentence unless effective provision shall be made so as to give
effect to the provisions set forth in this Section 16.04. The provisions of this
Section 16.04 shall apply similarly to successive consolidations, mergers, sales
or conveyances.

     any Conversion Agent for such Debt Securities a certificate of the
     Treasurer of the Company, stating the adjusted Conversion Price determined
     as provided herein and setting forth in reasonable detail such facts as
     shall be necessary to show the reason for and the manner of computing such
     adjustment, such certificate to be conclusive evidence that the adjustment
     is correct; and

          (2)  a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be given by the
     Company, or at the Company's request, by the Trustee in the name and at the
     expense of the Company, in the manner provided in Section 1.05. Any notice
     so given shall be conclusively presumed to have been duly given, whether or
     not the Holder receives such notice.

     for which approval of any stockholders of the Company is required, or of
     the sale or conveyance to another Person or entity or group of Persons or
     entities acting in concert as a partnership, limited partnership, syndicate

Conversion Agent for the applicable Debt Securities, and shall cause to be
given, to the Holders of applicable Debt Securities in the manner provided in
Section 1.05, at least fifteen (15) days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record is to be

for securities or other property deliverable upon such reclassification,
consolidation, merger, sale, conveyance, dissolution, liquidation or winding up.

legality or validity of the proceedings described in clause (1), (2) or (3) of

          (a)  The Company shall at all times reserve and keep available, free
from preemptive rights, out of its authorized but unissued shares of its Equity
Securities, for the purpose of effecting the conversion of the Debt Securities,
such number of its duly authorized shares of Equity Securities as shall from
time to time be sufficient to effect the conversion of all applicable
Outstanding Debt Securities into such Equity Securities at any time (assuming
that, at the time of the computation of such number of shares or securities, all
such Debt Securities would be held by a single holder); provided, however, that
                                                        --------  -------
nothing contained herein shall preclude the Company from satisfying its
obligations in respect of the conversion of the Debt Securities by delivery of
purchased shares of Equity Securities which are held in the treasury of the
Company. The Company shall from time to time, in accordance with the laws of the
Commonwealth of Pennsylvania, use its best efforts to cause the authorized
amount of the Equity Securities to be increased if the aggregate of the
authorized amount of the Equity Securities remaining unissued and the issued
shares of such Equity Securities in its treasury (other than any such shares
reserved for issuance in any other connection) shall not be sufficient to permit
the conversion of all Debt Securities. The Company covenants that all shares of
Equity Securities which may be issued upon conversion of Debt Securities will
upon issue be fully paid and nonassessable and free from all liens and charges
and, except as provided in Section 16.08, taxes with respect to the issue
thereof.

          (b)  If any shares of Equity Securities which would be issuable upon
conversion of Debt Securities hereunder require registration with or approval of
any governmental authority before such shares or securities may be issued upon
such

conversion, the Company will in good faith and as expeditiously as possible
endeavor to cause such shares or securities to be duly registered or approved,
as the case may be. The Company further covenants that so long as the Equity
Securities shall be listed on the New York Stock Exchange, the Company will, if
permitted by the rules of such exchange, list and keep listed all Common Stock
issuable upon conversion of the Debt Securities, and the Company will endeavor
to list the shares of Equity Securities required to be delivered upon conversion
of the Debt Securities prior to such delivery upon any other national securities
exchange upon which the outstanding Equity Securities are listed at the time of
such delivery.

          Section 16.08. Taxes on Conversion.
                         -------------------

          The issue of stock certificates on conversion of Debt Securities shall
be made without charge to the converting Holder for any tax in respect of the
issue thereof, and the Company shall pay any and all documentary, stamp or
similar issue or transfer taxes that may be payable in respect of the issue or
delivery of shares of Equity Securities on conversion of Debt Securities
pursuant hereto. The Company shall not, however, be required to pay any such tax
which may be payable in respect of any transfer involved in the issue or
delivery of shares of Equity Securities or the portion, if any, of the Debt
Securities which are not so converted in a name other than that in which the
Debt Securities so converted were registered (in the case of Registered
Securities), and no such issue or delivery shall be made unless and until the
Person requesting such issue has paid to the Company the amount of such tax or
has established to the satisfaction of the Company that such tax has been paid.

          Section 16.09. Conversion After Record Date.
                         ----------------------------

          If any Registered Securities are surrendered for conversion subsequent
to the record date preceding an Interest Payment Date but on or prior to such
Interest Payment Date (except Registered Securities called for redemption on a
Redemption Date between such record date and Interest Payment Date), the Holder
of such Registered Securities at the close of business on such record date shall
be entitled to receive the interest payable on such Registered Securities on
such Interest Payment Date notwithstanding the conversion thereof. Registered
Securities surrendered for conversion during the period from the close of
business on any record date next preceding any Interest Payment Date to the
opening of business on such Interest Payment Date shall (except in the case of
Registered Securities which have been called for redemption on a Redemption Date
within such period, in which case, notwithstanding anything to the contrary
contained in this Indenture, no interest payment shall be made on such Interest
Payment Date to the Holders of such Registered Security on such record date) be
accompanied by payment in New York Clearing House funds or other funds and in
the Currency in which such Registered Security is payable or another Currency
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the Registered Securities being

surrendered for conversion. Except as provided in this Section 16.09 and Section
16.02(c), no adjustments in respect of payments of interest on Debt Securities
surrendered for conversion or any dividends or distributions or interest on the
Equity Securities issued upon conversion shall be made upon the conversion of
any Debt Securities.

          Section 16.10. Company Determination Final.
                         ---------------------------

          Any determination that the Company or the Board of Directors must make
pursuant to this Article shall be conclusive if made in good faith and in
accordance with the provisions of this Article, absent manifest error.

          Section 16.11. Trustee's Disclaimer.
                         --------------------

          The Trustee has no duty to determine when an adjustment of the
Conversion Price should be made, how it should be made or what it should be. The
Trustee makes no representation and shall not be accountable as to the validity
or value of any securities or assets issued upon conversion of Debt Securities.
The Trustee shall not be responsible for the Company's failure to comply with
this Article. Each Conversion Agent other than the Company shall have the same
protection under this Section as the Trustee.



          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed, all as of the day and year first above written.
