         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all

be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company and the Guarantor. Such

anything done, omitted or suffered to be done by the Trustee, the Company or the
Guarantor in reliance thereon, whether or not notation of such action is made

     shall be sufficient for every purpose hereunder if made, given, furnished

     in writing to or with the Trustee at its Corporate Trust Office, Attention:
     Institutional Trust Services, or

         (2) the Company or the Guarantor by the Trustee or by any Holder shall
     be sufficient for every purpose hereunder (unless otherwise herein
     expressly provided) if made, given, furnished or filed in writing, in the
     case of the Company, to or with it at the address of its principal office
     specified in the first paragraph of this instrument, Attention: _______, or
     at any other address previously furnished in writing to the Trustee by the

Section 106. Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

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

     If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

Guarantees shall be governed by the laws of the respective jurisdictions of

(other than a provision of the Securities of any series which specifically

interest or principal (and premium, if any) need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest

the time Outstanding, on behalf of the Holders of all Securities of such series,
to waive compliance by the Company or the Guarantor, or both, with certain

their consequences. Any such consent or waiver by the Holder of this Security

Holder of this Security shall not have the right to institute any proceeding

Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee

Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed or provided for herein.

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

thereof. As provided in the Indenture and subject to certain limitations therein
set forth, Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series of a different authorized
denomination, as requested by the Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient in cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Guarantor, the Trustee and any agent of the Company, the
Guarantor or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes (subject to Section 307 of the
Indenture), whether or not this Security be overdue, and neither the Company,
the Guarantor, the Trustee nor any such agent shall be affected by notice to the
contrary.

         The Indenture provides that the Company and the Guarantor, at the
Guarantor's option, (a) will be discharged from any and all obligations in
respect of the Securities (except for certain obligations to register the
transfer or exchange of Securities, replace stolen, lost or mutilated
Securities, maintain paying agencies and hold moneys for payment in trust) or
(b) need not comply with certain restrictive covenants of the Indenture, in each
case if the Company or the Guarantor deposits, in trust, with the Trustee money
or Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money, in an
amount sufficient to pay all the principal (including any mandatory sinking fund
payments) of, and (premium, if any) and interest on, the Securities on the dates
such payments are due in accordance with the terms of such Securities and
Guarantees, and certain other conditions are satisfied.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

entitled; provided, however, that the Guarantor shall not be required to make
any payment of additional amounts (1) for or on account of any such tax,
assessment or governmental charge imposed by the United States or any political
subdivision or taxing authority thereof or therein or (2) for or on account of:

         (a) any tax, assessment or other governmental charge which would not
have been imposed but for (i) the existence of any present or former connection
between such Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of a power over, such Holder, if such Holder is an
estate, trust, partnership or corporation) and the taxing jurisdiction or any
political subdivision or territory or possession thereof or area subject to its
jurisdiction, including, without limitation, such Holder (or such fiduciary,
settlor, beneficiary, member, shareholder or possessor) being or having been a
citizen or resident thereof or being or having been present or engaged in trade
or business therein or having or having had a permanent establishment therein or
(ii) the presentation of a Security of such series (where presentation is
required) for payment on a date more than 30 days after the date on which such
payment became due and payable or the date on which payment thereof is duly
provided for, whichever occurs later;

         (b) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

         (c) any tax, assessment or other governmental charge which is payable
otherwise than by withholding from payments of (or in respect of) principal of,
or any interest on, the Securities of such series;

         (d) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of the
Security of such series (i) to provide information concerning the nationality,
residence or identity of the Holder or such beneficial owner or (ii) to make any
declaration or other similar claim or satisfy any information or reporting
requirements, which, in the case of (i) or (ii), is required or imposed by a
statute, treaty, regulation or administrative practice of the taxing
jurisdiction as a precondition to exemption from all or part of such tax,
assessment or other governmental charge;

         (e) any tax, assessment or other governmental charge which such Holder
would have been able to avoid by presenting such Security to another Paying
Agent;

         (f) any tax, assessment or other governmental charge which is imposed
on a payment pursuant to any European Union Directive on the taxation of savings
implementing the conclusions of the ECOFIN Council meeting of November 26 and
27, 2000, or any law implementing such directive;

         or (g) any combination of items (a), (b), (c), (d), (e) and (f) above;
nor shall additional amounts be paid with respect to any payment of the
principal of, or any interest

on, any Security of such series to any Holder who is a fiduciary or partnership
or other than the sole beneficial owner of such payment to the extent such
payment would be required by the laws of the jurisdiction (or any political
subdivision or taxing authority thereof or therein) to be included in the income
for tax purposes of a beneficiary or settlor with respect to such fiduciary or a
member of such partnership or a beneficial owner who would not have been
entitled to such additional amounts had it been the Holder of such Security.

         The foregoing provisions shall apply mutatis mutandis to any
withholding or deduction for or on account of any present or future taxes,
assessments or governmental charges of whatever nature of any jurisdiction in
which any successor Person to the Guarantor is organized, or any political
subdivision or taxing authority thereof or therein.

         The Guarantor hereby agrees that its obligations hereunder shall be as
if it were principal debtor and not merely surety, and shall be absolute and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of such Security or such Indenture, any failure
to enforce the provisions of such Security or such Indenture, or any waiver,
modification or indulgence granted to the Company with respect thereto, by the
Holder of such Security or such Trustee, or any other circumstance which may
otherwise constitute a legal or equitable discharge of a surety or guarantor;
provided, however, that, notwithstanding the foregoing, no such waiver,
modification or indulgence shall, without the consent of the Guarantor, increase
the principal amount of such Security or the interest rate thereon or increase
any premium payable upon redemption thereof. The Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger or bankruptcy of the Company, any right to require a proceeding
first against the Company, protest or notice with respect to such Security or
the indebtedness evidenced thereby [or with respect to any sinking fund payment
required under such Security] and all demands whatsoever, and covenants that
this Guarantee will not be discharged except by payment in full of the principal
of (and premium, if any) and interest on such Security. This is a guarantee of
payment and not of collection.

         The Guarantor shall be subrogated to all rights of the Holder of such
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor pursuant to the provisions of this Guarantee; provided, however,
that the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of
(and premium, if any) and interest on all Securities of the same series issued
under such Indenture shall have been paid in full.

         No reference herein to such Indenture and no provision of this
Guarantee or of such indenture shall alter or impair the guarantee of the
Guarantor, which is absolute and unconditional, of the due and punctual payment
of the principal of (and premium, if any) and interest on the Security upon
which this Guarantee is endorsed at the times, place and rate, and in the cash
or currency prescribed therein.

                 (18) with respect to such series of Securities, the "Stated

<PAGE>

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

         All Securities of any one series shall be substantially identical
except as to denomination and number and except as may otherwise be provided in
or pursuant to such Board Resolutions and set forth (or determined in the manner
provided in) in such Officers' Certificates or in any such indenture
supplemental hereto.

         If any of the terms of the series are established by action taken
pursuant to a Board Resolution of the Company or the Guarantor, a copy of an
appropriate record of such action shall be certified by the Secretary or an
Assistant Secretary of the Company or by the Secretary, a Deputy Secretary, an
Assistant Secretary or a Deputy Assistant Secretary of the Guarantor, as the
case may be, and delivered to the trustee at or prior to the delivery of the

         With respect to Securities of a series offered in a Periodic Offering,
the Board Resolution (or action taken pursuant thereto), Officers' Certificate
or supplemental indenture referred to above may provide general terms or
parameters for Securities of such series and provide either that the specific
terms of particular Securities of such series shall be specified in a Company
Order or that such terms shall be determined by the Company in accordance with
other procedures specified in a Company Order as contemplated by the third
paragraph of Section 303.

         Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount

series may be issued up to the maximum aggregate principal amount authorized
with respect to such series as increased.

Section 302. Denominations.

         The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301. In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

         The Securities shall be executed on behalf of the Company by one of its
Directors or senior officers and attested by its Secretary or one of its
Assistant Secretaries. The signature of any of such director or officer on the
Securities may be manual or facsimile.

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

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company having endorsed thereon Guarantees executed by the Guarantor to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that in
                                                      --------  -------
the case of Securities offered in a Periodic Offering, the Trustee shall
authenticate and deliver such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee
of oral or electronic instructions from the Company or its duly authorized
agents, promptly confirmed in writing) acceptable to the Trustee as may be
specified by or pursuant to a Company Order delivered to the Trustee prior to
the time of the first authentication of Securities of such series. If the form
or terms of the Securities of the series or the form of the Guarantees endorsed
thereon have been established by or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive, and (subject to 601)
shall be fully protected in relying upon, an Opinion of Counsel stating,

               (a)  if the form of such Securities or Guarantees has been
         established by or pursuant to Board Resolution as permitted by Section
         201, that such form has been established in conformity with the
         provisions of this Indenture;

               (b)  if the terms of such Securities have been, or in the case of
         Securities of a series offered in a Periodic Offering, will be,
         established by or pursuant to Board Resolution as permitted by Section
         301, that such terms have been, or in the case of Securities of a
         series offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject, in the
         case of Securities of a series offered in a Periodic Offering, to any
         conditions specified in such Opinion of Counsel;

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

               (d)  that such Guarantees, when the Securities upon which they
         shall have been endorsed shall have been authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Guarantor enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles.

                                       26

<PAGE>

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities or this Indenture or otherwise in a manner which
is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

         With respect to Securities of a series offered in a Periodic Offering,
the Trustee may rely, as to the authorization by the Company and the Guarantor
of any of such Securities and the related Guarantees, the form and terms thereof
and the legality, validity, binding effect and enforceability thereof, upon the
Opinion of Counsel and the other documents delivered pursuant to Sections 201
and 301 and this Section, as applicable, in connection with the first
authentication of Securities of such series.

         Each Security shall be dated the date of its authentication.

         No Security or Guarantee endorsed thereon shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Security a certificate of authentication substantially in
the form provided for herein executed by the Trustee by manual signature of an
authorized officer, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder and that such Security or Guarantee is entitled to the
benefits of this Indenture.

Section 304.  Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities substantially of the tenor of the definitive
Securities in lieu of which they are issued, and having endorsed thereon
Guarantees duly executed by the Guarantor substantially of the tenor of the
definitive Guarantees, which Securities and Guarantees may be printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities and the person duly
authorized thereto executing such Guarantees may determine, all as evidenced by
such execution.

         If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary

                                       27

<PAGE>

Securities of such series at the office or agency of the Company in a Place of
Payment for that series, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities of any series the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor one or more definitive Securities of the same series of authorized
denominations and of a like aggregate principal amount and tenor, having
endorsed thereon Guarantees duly executed by the Guarantor. Until so exchanged
the temporary Securities of any series shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities of such series.

Section 305.  Registration, Registration of Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office being herein
sometimes referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security of any
series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount and tenor, each such Security having endorsed thereon a
Guarantee duly executed by the Guarantor.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
a like aggregate principal amount and tenor, each such Security having endorsed
thereon a Guarantee duly executed by the Guarantor, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

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

         Every Security presented or surrendered for registration of transfer or
for 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.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of

                                       28

<PAGE>

transfer or exchange of Securities, other than exchanges pursuant to Section
304, 906 or 1107 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

         Each Global Security authenticated under this Indenture shall be
registered in the name of the Depositary designated for such Global Security or
a nominee thereof and delivered to such Depositary or a nominee thereof or
custodian therefor, and each such Global Security shall constitute a single
Security for all purposes of this Indenture.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any Global Security shall be exchangeable pursuant
to this Section 305 for Securities registered in the names of Persons other than
the Depositary for such series or its nominee if, but only if, (i) such
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such series or at any time ceases to be a clearing agency
registered as such under the Exchange Act, as amended, and the Company and/or
the Guarantor notify the Trustee that they are unable to locate a qualified
successor Depositary, (ii) the Company and/or the Guarantor executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (iii) there shall have occurred and be continuing an Event of
Default with respect to the Securities of such series and beneficial owners of
the Securities evidencing not less than 50% of the aggregate unpaid principal
amount of the Securities of such series advise the Trustee and the Depositary
through participants in writing that the continuation of a book-entry system is
no longer in the best interests of the beneficial owners of the Securities of
such series. Any Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Securities registered in such names as such
Depositary shall direct.

         Notwithstanding any other provision of this Indenture, a Global
Security may not be transferred except as a whole by the Depositary for such
Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.

Section 306.  Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount, having endorsed thereon a Guarantee duly executed by the Guarantor, and
bearing a number not contemporaneously outstanding.

                                       29

<PAGE>

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount, having endorsed thereon a Guarantee duly executed by the Guarantor, and
bearing a number not contemporaneously Outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security upon compliance with the
foregoing conditions.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company and the Guarantor, whether or
not the destroyed, lost or stolen Security shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued
hereunder.

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

Section 307.  Payment of Interest; Interest Rights Preserved.

         Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any 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 that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

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

                (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be

                                       30

<PAGE>

         fixed in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         Security or such series and the date of the proposed payment, and at
         the same time the Company shall deposit with the Trustee an amount of
         money equal to the aggregate amount proposed to be paid in respect of
         such Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this Clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first class postage
         prepaid, to each Holder of Securities of such series at his address as
         it appears in the Security Register, not less than 10 days prior to
         such Special Record Date. Notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor having been so
         mailed, such Defaulted Interest shall be paid to the Persons in whose
         names the Securities of such series (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         Clause (2).

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

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

Section 308.  Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Guarantor, the Trustee and any agent of the Company, the
Guarantor or the Trustee may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 307) interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and neither the Company, the Guarantor, the Trustee nor any agent of
the Company, the Guarantor or the Trustee shall be affected by notice to the
contrary.

                                       31

<PAGE>

         No holder of any beneficial interest in any Global Security held on its
behalf by a Depositary shall have any rights under this Indenture with respect
to such Global Security, and such Depositary may be treated by the Company, the
Guarantor, the Trustee, and any agent of the Company, the Guarantor or the
Trustee as the owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall impair, as between a
Depositary and such holders of beneficial interests, the operation of customary
practices governing the exercise of the rights of the Depositary as Holder of
any Security.

         None of the Company, the Guarantor, the Trustee or any agent of the
Company, the Guarantor or the Trustee shall have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests in a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

Section 309.  Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company or the Guarantor may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company or the Guarantor may
have acquired in any manner whatsoever, and may deliver to the Trustee (or to
any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of by
the Trustee in accordance with its customary procedures or as directed by a
Company Order.

Section 310.  Computation of Interest.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

Section 401.  Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

         than (i) Securities which have been destroyed, lost or stolen and which
         have been replaced or paid as provided in Section 306 and (ii)
         Securities for whose payment money has theretofore been deposited in
         trust or segregated and held in trust by the Company or the Guarantor
         and thereafter repaid to the Company or the Guarantor or discharged
         from such trust, as provided in Section 1006) have been delivered to
         the Trustee for cancellation; or

               (B) all such Securities not theretofore delivered to the Trustee
         for cancellation

                   (i)   have become due and payable, or

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

                   (iii) are to be called for redemption within one year under
               arrangements satisfactory to the Trustee for the giving of notice
               of redemption by the Trustee in the name, and at the expense, of
               the Company,

         and the Company or the Guarantor, in the case of (i), (ii) or (iii)
         above, has deposited or caused to be deposited with the Trustee as
         trust funds in trust for the purpose an amount sufficient to pay and
         discharge the entire indebtedness on such Securities not theretofore
         delivered to the Trustee for cancellation, for principal (and premium,
         if any) and interest to the date of such deposit (in the case of
         Securities which have become due and payable) or to the Stated Maturity
         or Redemption Date, as the case may be;

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

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

obligations of the Company and the Guarantor to the Trustee under Section 607,
the obligations of the Company and the Guarantor to any Authenticating Agent
under Section 614 and, if money shall have been deposited with the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1006 shall survive.

Section 402.  Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1006, all
money and the proceeds of any Government Obligations deposited with the Trustee
pursuant to Section 401 or 403 shall be held in trust and applied by it, in
accordance with the provisions of the Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company or
the Guarantor acting as Paying Agent) as the Trustee may determine, of the
principal (and premium, if any) and interest to the Holders of the series of
Securities for the payment in respect of which such money has been deposited
with the Trustee.

         The Company or the Guarantor shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against the
Government Obligations deposited pursuant to Section 403 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of Outstanding Securities.
The obligations of the Company and the Guarantor pursuant to this paragraph
shall be joint and several.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company or the Guarantor from time to time upon
Company Request any money or Government Obligations held by it as provided in
Section 403 with respect to any Securities which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect the Discharge or
Covenant Defeasance, as the case may be, with respect to such Securities.

Section 403.  Defeasance Upon Deposit of Moneys or Government Obligations.

         At the Guarantor's option, either (a) the Company and the Guarantor
shall each be deemed to have been Discharged (as defined below) from its
respective obligations with respect to any series of Securities on the 91st day
after the applicable conditions set forth below have been satisfied or (b) the
Company and the Guarantor shall cease to be under any obligation to comply with
any term, provision or condition set forth in Sections 801 or 802 or any
covenant set forth on any indenture supplemental to this Indenture or otherwise
established pursuant to Section 301, and noncompliance with such Sections or
covenants shall not give rise to any Event of Default under Section 501(4)
("Covenant Defeasance"), with respect to any series of Securities at any time
after the applicable conditions set fort below have been satisfied:

                (1)  the Company or the Guarantor shall have deposited or caused
         to be deposited irrevocably with the Trustee or its agent as trust
         funds in trust, specifically pledged as security for, and dedicated
         solely to, the benefit of the Holders of the Securities of such series
         (i) money in an amount, or (ii) Government Obligations of the
         government in the currency of which the Securities of such series are
         denominated which through the payment of interest and principal in
         respect thereof in accordance with their terms will provide, not later
         than 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 (ii) and (iii)) of a nationally recognized firm of independent
         public accountants expressed in a

                                       34

<PAGE>

         written certification thereof delivered to the Trustee, to pay and
         discharge each installment of principal (including mandatory sinking
         fund payments) of and interest on, the outstanding Securities of such
         series on the dates such installments of interest or principal are due
         or to and including the Redemption Date irrevocably designated by the
         Guarantor pursuant to subparagraph (5) hereof;

                (2) if the Securities of such series are then listed on the New
         York Stock Exchange, the Company or the Guarantor shall have delivered
         to the Trustee an Opinion of Counsel to the effect that the exercise of
         the option under this Section 403 would not cause such Securities to be
         delisted;

                (3) no Event of Default or event which with notice or lapse of
         time would become an Event of Default under Section 501(1), (2), (3),
         (5), (6) or (7) with respect to the Securities of such series shall
         have occurred and be continuing on the date of such deposit;

                (4) the Company or the Guarantor shall have delivered to the
         Trustee an Opinion of Counsel to the effect that holders of the
         Securities of such series will not recognize income, gain or loss for
         Federal income tax purposes as a result of the exercise of the option
         under this Section 403 and will be subject to Federal income tax on the
         same amount and in the same manner and at the same times as would have
         been the case if such option had not been exercised, and, in the case
         of Securities being Discharged, such opinion shall be accompanied by a
         private letter ruling to that effect received from the United States
         Internal Revenue Service or a revenue ruling pertaining to a comparable
         form of transaction to that effect published by the United States
         Internal Revenue Service;

                (5) if the Company or the Guarantor has deposited or caused to
         be deposited money or Government Obligations to pay or discharge the
         principal of (and premium, if any) and interest on the Outstanding
         Securities of a series to and including a Redemption Date pursuant to
         subparagraph (1) hereof, such Redemption Date shall be irrevocably
         designated by a Board Resolution delivered to the Trustee on or prior
         to the date of deposit of such money or Government Obligations and such
         Board Resolution shall be accompanied by an irrevocable Company Request
         that the Trustee give notice of such redemption in the name and at the
         expense of the Company not less than 30 nor more than 60 days prior to
         such Redemption Date in accordance with Section 1104; and

                (6) the Company or the Guarantor shall have delivered to the
         Trustee an Officers' Certificate and an Opinion of Counsel, each
         stating that all conditions precedent with respect to such Discharge or
         Covenant Defeasance have been complied with.

"Discharged" means that the Company and Guarantor shall be deemed to have paid
and discharged the entire indebtedness represented by, and obligations under,
the Securities of such series and the Guarantees endorsed thereon and to have
satisfied all the obligations under this Indenture relating to the Securities of
such series and the

                                       35

<PAGE>

Guarantees endorsed thereon (and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging the same), except (A) the rights
of holders of Securities of such series to receive, from the trust fund
described in clause (1) above payment of the principal of and the interest on
such Securities when such payments are due; (B) the Company's or the Guarantor's
obligations, as the case may be, with respect to such Securities under Sections
305, 306, 1002, 1005 and 1006; and (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder.

         Notwithstanding any Covenant Defeasance with respect to Sections 801
and 802, any corporation or Person that would otherwise have been required to
assume the obligations of the Company or the Guarantor pursuant to said Sections
shall be required, as a condition to any merger, consolidation, amalgamation,
transfer, conveyance or lease contemplated thereby, to assume the obligations of
the Company or the Guarantor, as the case may be, to the Trustee under Sections
402 and 607.

         trustee, sequestrater or similar official of the Company or the
         Guarantor or of the whole or substantially all of its property, or the
         making by it of an assignment for the benefit of 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 or
         the Guarantor in furtherance of any such action; or

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

         Upon receipt by the Trustee of any Notice of Default pursuant to this
Section 501, (i) with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established, which
record date shall be at the close of business on the day the Trustee receives
such Notice of Default, and (ii) with respect to

                                       37

<PAGE>

any other series of Securities, the Trustee may, but shall not be obligated to,
establish a record date, in each case for the purpose of determining Holders of
Outstanding Securities of such series entitled to join in such Notice of
Default. If such record date is fixed, the Holders on such record date, or their
duly designated proxies, and only such Persons, shall be entitled to join in
such Notice of Default, whether or not such Holders remain Holders after such
record date; provided, however, that unless Holders of at least the requisite
principal amount (which amount shall be 25% in the case of subclause (4) of this
Section) of the Outstanding Securities of such series, or their proxies, shall
have joined in such Notice of Default prior to the day which is 90 days after
such record date, such Notice of Default and the Act of Holders, or their
proxies, joining in such Notice of Default shall automatically and without
further action by any Holders be cancelled and of no effect. Nothing in this
paragraph shall prevent a Holder, or a proxy of a Holder, from giving, (i) after
expiration of such 90-day period, a new Notice of Default to the same effect as
that cancelled pursuant to the proviso to the preceding sentence, or (ii) during
any such 90-day period in respect of any Notice of Default with respect to a
prospective Event of Default with respect to Securities of such series, an
additional Notice of Default with respect to any other prospective Event of
Default (other than a prospective Event of Default as to which such a 90-day
period has not expired) with respect to Securities of such series, in either of
which events a new record date shall or may, as the case may be, be established
pursuant to the provisions of this Section 501 in respect of such new or
additional Notice of Default.

Section 502.  Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount (or, if the Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities
of that series to be due and payable immediately, by a notice in writing to the
Company and the Guarantor (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.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company, the
Guarantor and the Trustee, may rescind and annul such declaration and its
consequences if

                (1) the Company or the Guarantor has paid or deposited with the
     Trustee a sum sufficient to pay

                    (A) all overdue interest on all Securities of that series,

                                       38

<PAGE>

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

                (C) to the extent that payment of such interest is lawful,
         interest upon overdue interest at the rate or rates prescribed therefor
         in such Securities, and

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

     and

         (2)    all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

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

         Upon receipt by the Trustee of any written notice declaring such an
acceleration, or rescission and annulment thereof, (i) with respect to
Securities of a series all or part of which is represented by a Global Security,
a record date shall be established, which record date shall be at the close of
business on the day the Trustee receives such notice, and (ii) with respect to
any other series of Securities, the Trustee may, but shall not be. obligated to,
establish a record date, in each case for the purpose of determining Holders of
Outstanding Securities of such series entitled to join in such notice. If such
record date is fixed, the Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such Holders remain Holders after such record date; provided,
however, that unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, and the Act of Holders, or their
proxies, joining in such notice shall automatically and without further action
by any Holders be cancelled and of no effect. Nothing in this paragraph shall
prevent a Holder, or a proxy of a Holder, of Securities of any series from
giving, (i) after expiration of such 90-day period, a new written notice of
declaration of acceleration, or rescission and annulment thereof, as the case
may be, to the same effect as that cancelled pursuant to the proviso to the
preceding sentence, or (ii) during any such 90-day period in respect of any
written notice of declaration of acceleration or rescission and annulment
thereof, as the case may be, with respect to any Event of Default with respect
to Securities of such series, an additional written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, with
respect to any other Event of Default (other than an

                                       39

<PAGE>

         Event of Default as to which such a 90-day period has not expired) with
         respect to Securities of such series, in either of which events a new
         record date shall or may, as the case may be, be established pursuant
         to the provisions of this Section 502 in respect of such new or
         additional written notice.

 Section 503. Collection of Indebtedness and Suits for Enforcement by
 Trustee.

                The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
or rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company, the Guarantor or any other obligor upon such Securities and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company, the Guarantor or any other obligor upon
such Securities, wherever situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

Section 504.  Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Company, the Guarantor of any other
obligor upon the Securities or the property of the Company, the Guarantor or of
such other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities shall then be due and

                                       40

<PAGE>

payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company or the Guarantor
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise, to take any and all
actions authorized under the Trust Indenture Act in order to have claims of the
Holders and the Trustee allowed in any such proceeding. In particular, the
Trustee shall be authorized,

         (i)  to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     in accordance with the terms thereof and to file such other papers or
     documents as may be necessary or advisable in order to have the claims of
     the Trustee (including any claim for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and of
     the Holders allowed in such judicial proceeding, and

         (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrate or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

         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 Securities
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.

Section 505. Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

Section 506. Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of

                                       41

<PAGE>

the Securities and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:

         First: To the payment of all amounts due the Trustee under Section 607;
     and

         Second: To the payment of the amounts then due and unpaid for principal
     of (and premium, if any) and interest on the Securities in respect of which
     or for the benefit of which such money has been collected, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on such Securities for principal (and premium, if any) and
     interest, respectively.

Section 507.  Limitation on Suits.

     No Holder of any Security 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 the Securities of that series;

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

                                       42

<PAGE>

Section 508.  Unconditional Right of Holders to Receive Principal, Premium and
Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on such Security on the Stated Maturity or Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment, and such
rights shall not be impaired without the consent of such Holder.

Section 509.  Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company and the Guarantor shall be
restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

Section 510.  Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 511.  Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

Section 512.  Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

                                       43

<PAGE>

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

                (2) the Trustee may take any other action deemed proper by the
        Trustee which is not inconsistent with such direction, and

                (3) subject to the provisions of Section 601, the Trustee shall
        have the right to decline to follow any such direction if the Trustee in
        good faith shall, by a Responsible Officer or Officers of the Trustee,
        determine that the proceeding so directed would involve the Trustee in
        personal liability.

        Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, (i) with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established, which
record date shall be at the close of business on the day the Trustee receives
such notice, and (ii) with respect to any other series of Securities, the
Trustee may, but shall not be obligated to, establish a record date, in each
case for the purpose of determining Holders of Outstanding Securities of such
series entitled to join in such notice. If such record date is fixed, the
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such notice, whether or not such Holders
remain Holders after such record date; provided, however, that unless the
Holders of not less than a majority in principal amount of the Outstanding
Securities of such series shall have joined in such notice prior to the date
which is 90 days after such record date, such notice and the Act of Holders, or
their proxies, joining in such notice shall automatically and without further
action by any Holders be cancelled and of no effect. Nothing in this paragraph
shall prevent a Holder, or a proxy of a Holder, from giving, (i) after
expiration of such 90-day period, a new notice to the same effect as that
cancelled pursuant to the proviso to the preceding sentence, or (ii) during any
such 90-day period in respect of any notice, a new notice giving directions
contrary to or otherwise different from such notice in either of which events a
new record date shall or may, as the case may be, be established pursuant to the
provisions of this Section 512 in respect of such new notice.

Section 513.  Waiver of Past Defaults.

        The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

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

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

                                       44

<PAGE>

         With respect to any series of Securities, the Company may, but shall
not be obligated to, establish a record date for the purpose of determining the
Persons entitled to waive any past default hereunder. If a record date is fixed,
the Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to waive any default hereunder, whether or not such
Holders remain Holders after such record date; provided, however, that unless
such Holders of not less than a majority in principal amount of the Outstanding
Securities of such series shall have waived such default prior to the date which
is 90 days after such record date, any such waiver previously given shall
automatically and without further action by any Holder be cancelled and of no
effect.

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

Section 514. Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, in the manner and to the extent provided
in the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company,
the Guarantor or the Trustee.

Section 515. Waiver of Stay or Extension Laws.

         The Company and the Guarantor each covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company and
the Guarantor each (to the extent that it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

                                   The Trustee

Section 601.   Certain Duties and Responsibilities.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

Section 602.   Notice of Defaults.

         Within 90 days after the occurrence known to the Trustee of any default
hereunder with respect to the Securities of any series, the Trustee shall
transmit by mail to all Holders of Securities of such series, as their names and
addresses appear in the Security Register, notice of all such defaults
hereunder, unless such default shall have been cured or waived provided,
however, that, except in the case of a default in the payment of the principal
of (or premium, if any) or interest on any Security of such series or in the
payment of any sinking fund installment with respect to Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of
directors or Responsible Officers of the Trustee in good faith determine that
the withholding of such notice is in the interest of the Holders of Securities
of such series; and provided, further, that, in the case of any default of the
character specified in Section 501(4) with respect to Securities of such series,
no such notice to Holders shall be given until at least 30 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 Securities of such series.

Section 603.   Certain Rights of Trustee.

         Subject to the provisions of Section 601:

               (a)  the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document 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 or the Guarantor
         mentioned herein shall be sufficiently evidenced by a Company Request
         or

                                       46

<PAGE>

         Company Order and any resolution of the Board of Directors of the
         Company or the Guarantor shall be sufficiently evidenced by a Board
         Resolution;

               (c)  whenever in the administration of this Indenture the Trustee
         shall deem it desirable that a matter be proved or established prior to
         taking, suffering or omitting any action hereunder, the Trustee (unless
         other evidence be herein specifically prescribed) may, in the absence
         of bad faith on its part, rely upon an Officers' Certificate;

               (d)  the Trustee may consult with counsel and the written advice
         of such counsel or any Opinion of Counsel shall be full and complete
         authorization and protection in respect of any action taken, suffered
         or omitted by it hereunder in good faith and in reliance thereon;

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

               (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, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine the
         relevant books, records and premises of the Company and the Guarantor,
         personally or by agent or attorney; and

               (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 attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder.

Section 604.   Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company or the Guarantor, and the Trustee or any Authenticating Agent
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee or any Authenticating Agent shall not be accountable for
the use or application by the Company of Securities or the proceeds thereof.

Section 605.   May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company or the Guarantor, in its individual
or any other capacity, may become the owner or pledgee of Securities and,
subject to Sections 608 and 613, may otherwise deal with the Company and the
Guarantor with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

Section 606.   Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company or the Guarantor, as the case may be.

Section 607.   Compensation and Reimbursement.

         The Company and the Guarantor agree

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

               (2)  except as otherwise expressly provided herein, to reimburse
         the Trustee upon its request for all reasonable expenses, disbursements
         and advances incurred or made by the Trustee in accordance with any
         provision of this Indenture (including the reasonable compensation and
         the expenses and disbursements of its agents and counsel), except any
         such expense, disbursement or advance as may be attributable to its
         negligence or bad faith; and

               (3)  to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense incurred without negligence or
         bad faith on its part, arising out of or in connection with the
         acceptance or administration of the trust or trusts hereunder,
         including the costs and expenses of defending itself against (but not
         of instituting) any claim or liability in connection with the exercise
         or performance of any of its powers or duties hereunder.

         As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
such Securities.

                                       48

<PAGE>

         The obligations of the Company and the Guarantor under this Section
shall be joint and several.

         The provisions of this Section shall survive the satisfaction and
discharge of this Indenture.

Section 608.   Disqualification; Conflicting Interests.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall, as soon as practicable
and in any event within 90 days after ascertaining that it has such conflicting
interest, and if the Event of Default (as defined in Section 501 hereof) to
which such conflicting interest relates has not been cured or duly waived or
otherwise eliminated before the end of such 90-day period, either eliminate such
conflicting interest or resign to the extent and in the manner provided by, and
subject to the provisions of, the Trust Indenture Act and this Indenture. To the
extent permitted by such Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this Indenture with
respect to Securities of more than one series or by virtue of being a trustee
under this Indenture and under any indenture listed in Annex A hereto.

Section 609.   Corporate Trustee Required; Eligibility.

         There shall at all times be one and only one Trustee hereunder with
respect to the Securities of each series, which may be a Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, and has a combined
capital and surplus of at least $50,000,000, subject to supervision or
examination by Federal or state authority. If such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section and to
the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

Section 610.   Resignation and Removal; Appointment of Successor.

               (a)  No resignation or removal of the Trustee and no appointment
of a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

               (b)  The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of

                                       49

<PAGE>

acceptance by a successor Trustee required by Section 611 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
Securities of such series.

         (c) In accordance with the requirements of Section 315(e) of the Trust
Indenture Act, the Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company and the Guarantor.

     (d)  If at any time:

     (1)  the Trustee shall fail to comply with Section 608 after
          written request therefor by the Company or the Guarantor or by
          any Holder who has been a bona fide Holder of a Security for at
          least six months, or

     (2)  the Trustee shall cease to be eligible under Section
          609 and shall fail to resign after written request therefor by
          the Company or the Guarantor 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 a Board Resolution may
remove the Trustee with respect to all Securities, or (ii) subject to
Section 514, any Holder who has been a bona fide Holder of a Security
for at least six months may, subject to the requirements of the Trust
Indenture Act on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the
Trustee with respect to all Securities and the appointment of a
successor Trustee or Trustees.

         (e)  If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of Trustee for any
cause, with respect to the Securities of one or more series, the
Company, by a Board Resolution, shall promptly appoint a successor
Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be
appointed with respect to the Securities of one or more or all of such
series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply
with the applicable requirements of Section 611. If, within one year
after such resignation, removal or incapability, or the occurrence of
such vacancy, a successor Trustee with respect to the Securities of any
series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series delivered
to the Company and the Guarantor and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of
such appointment in accordance with the applicable requirements of
Section 611, become the successor Trustee with respect to the
Securities of such series and to that extent supersede the successor
Trustee appointed by

                                       50

<PAGE>

the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

Section 611.  Acceptance of Appointment by Successor.

     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company, the Guarantor 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 the request of the Company, the Guarantor 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.

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

                                       51

<PAGE>

execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein
and each such successor Trustee, without any further act, deed or conveyance,
shall become vested with all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates; but, on request of the
Company and the Guarantor or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

     (c) Upon request of any such successor Trustee, the Company and the
Guarantor 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 the
requirements of the Trust Indenture Act.

Section 612.  Merger, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or with which it may
be consolidated, or any corporation resulting from any merger or consolidation
to which the Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder, provided such corporation shall be otherwise
qualified under the requirements of the Trust Indenture Act and eligible under
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

Section 613.  Preferential Collection of Claims Against Company.

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

Section 614.  Appointment of Authenticating Agent.

     At any time when any of the Securities remain Outstanding the Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes

                                       52

<PAGE>

as if authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any state thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or state 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 the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

     The Company and the Guarantor agree to pay to each Authenticating Agent
from time to time reasonable compensation for its services under this Section.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the

                                       53

<PAGE>

Trustee's certificate of authentication, an alternate certificate of
authentication in the following form:

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

destroy any list furnished to it as provided in Section 701 upon receipt of a

previous 12 months (but if no such event has occurred within such period,
no such report need be transmitted):

     previously reported; and

may elect) to report such advances to the Holders of Securities of any series if

purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of modifying in any manner the rights of
the Holders of Securities of such series under this Indenture; provided,
however, that no such supplemental indenture shall, without the consent of the
Holder of each Outstanding Security affected thereby,

          (1) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an

     Indenture, or

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

     thereby, provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1009, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611(b) and 901(8), or

          (4) change in any manner adverse to the interests of the Holders of
     Securities the terms and conditions of the obligations of the Guarantor in
     respect of the due and prompt payment of the principal thereof (and

     in respect thereof.

     A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the

shall be deemed not to affect the rights under this Indenture of the Holders of
Securities of any other series.

     With respect to any series of Securities, the Company may, but shall not be
obligated to, establish a record date for the purpose of determining the Persons
entitled to consent to any indenture supplemental hereto. If a record date is
fixed, the Holders on such record date, or their duly designated proxies, and
only such Persons, shall be entitled to consent to such supplemental indenture,
whether or not such Holders remain Holders after such record date; provided,
however, that unless such consent shall have become effective by virtue of the
requisite percentage having been obtained prior to the date which is 90 days
after such record date, any such consent previously given shall automatically
and without further action by any Holder be cancelled and of no effect.

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

Section 903.   Execution of Supplemental Indentures.

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,

obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

Section 904.   Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

Section 905.   Conformity with Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company and the Guarantor
shall so determine, new Securities of any series so modified as to conform, in
the opinion of the Trustee, the Company and the Guarantor, to any such
supplemental Indenture may be prepared and

                                       61

executed by the Company, the Guarantees endorsed thereon may be executed by the

or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes or where such notices or demands may be
served and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

endorsed on the Securities of that series

                                       62

<PAGE>

and this Indenture may be served. The Guarantor will give prompt written notice
to the Trustee of the location, and any change in the location, of such office
or agency. If at any time the Guarantor shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Guarantor hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

     The Guarantor may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for such purpose or where such notices or demands may be served
and may from time to time rescind such designations; provided, however, that no
such designation or rescission shall in any manner relieve the Guarantor of its
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Guarantor will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

Section 1006.  Money for Securities Payments to Be Held in Trust.

     If the Company or the Guarantor shall at any time act as Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
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 for any series of
Securities, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held as provided by the Trust Indenture Act, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

     The Company will cause each Paying Agent for any series of 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:

          (i) comply with the provisions of the Trust Indenture Act applicable
     to it as a Paying Agent and

          (ii) during the continuance of any such default by the Company (or any
     other obligor on the Securities of that series) in the making of any
     payment in respect of the Securities of that series, upon the written
     request of the Trustee, forthwith pay to the Trustee all sums held in trust
     by such Paying Agent for payment in respect of the Securities of such
     series.

                                       63

<PAGE>

     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 or the Guarantor, in trust for the payment of the principal of (and
premium, if any) or interest on any 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 be paid to the Company or the Guarantor, as the
case may be, on Company Request, or (if then held by the Company or the
Guarantor) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company and
the Guarantor 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
or the Guarantor as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, The City of
New York, New York, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to the Company or the Guarantor, as the case may be.

Section 1007.  Corporate Existence.

     Subject to Article Eight, the Company and the Guarantor will preserve and
keep in full force and effect their respective corporate existences.

Section 1008.  Statement by Executive Officers as to Compliance.

     The Company and the Guarantor will each deliver to the Trustee, within 120
days after the end of each fiscal year of the Guarantor ending after the date
hereof, an Executive Officer's Certificate (which need not comply with the
requirements of Section 102), stating whether or not to the best knowledge of
the signers thereof the Company or the Guarantor, as the case may be, has
complied with all conditions and covenants on their part contained in this
Indenture, and if such signers have obtained knowledge of any default by the
Company or the Guarantor in the performance, observance or fulfillment of any
such condition or covenant, specifying all such defaults and the nature and
status thereof of which they may have knowledge. For the purpose of this Section
1008, such compliance with the terms, conditions and covenants of the Indenture
shall be determined without regard to any period of grace or requirement of
notice provided hereunder.

                                       64

<PAGE>

Section 1009.  Waiver of Certain Covenants.

     The Company and the Guarantor may omit in any particular instance to comply
with any term, provision or condition set forth in any covenant set forth in any
indenture supplemental to this Indenture or otherwise established pursuant to
Section 301 with respect to the Securities of any series or the Guarantees
endorsed thereon if before the time for such compliance the Holders of at least
a majority in principal amount of the Outstanding 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 so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the Guarantor and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

     With respect to any series of Securities, the Company may, but shall not be
obligated to, establish a record date for the purpose of determining the Persons
entitled to waive any such term, provision or condition. If a record date is
fixed, the Holders on such record date, or their duly designated proxies, and
only such Persons, shall be entitled to waive any such term, provision or
condition hereunder, whether or not such Holders remain Holders after such
record date; provided, however, that unless the Holders of at least a majority
in principal amount of the Outstanding Securities of such series shall have
waived such term, provision or condition prior to the date which is 90 days
after such record date, any such waiver previously given shall automatically and
without further action by any Holder be cancelled and of no effect.

Section 1010.  Additional Amounts.

     Unless otherwise specified in any Board Resolution of the Guarantor
establishing the Guarantees relating a series of Securities in accordance with
Section 301, if any deduction or withholding for any present or future taxes,
assessments or other governmental charges of the jurisdiction (or any political
subdivision or taxing authority thereof or therein) in which the Guarantor is
incorporated, shall at any time be required by such jurisdiction (or any such
political subdivision or taxing authority) in respect of any amounts to be paid
by the Guarantor under the Guarantees, the Guarantor will pay to the Holder of a
Security of such series such additional amounts as may be necessary in order
that the net amounts paid to such Holder of such Security who, with respect to
any such tax, assessment or other governmental charge, is not resident in such
jurisdiction, after such deduction or withholding, shall be not less than the
amounts specified in such Security to which such Holder is entitled; provided,
however, that the Guarantor shall not be required to make any payment of
additional amounts (1) for or on account of any such tax, assessment or
governmental charge imposed by the United States or any political subdivision or
taxing authority thereof or therein or (2) for or on account of:

     (a) any tax, assessment or other governmental charge which would not have
been imposed but for (i) the existence of any present or former connection
between such Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of a power over, such Holder, if such Holder is an
estate, trust, partnership or

                                       65

<PAGE>

corporation) and the taxing jurisdiction or any political subdivision or
territory or possession thereof or area subject to its jurisdiction, including,
without limitation, such Holder (or such fiduciary, settlor, beneficiary,
member, shareholder or possessor) being or having been a citizen or resident
thereof or being or having been present or engaged in trade or business therein
or having or having had a permanent establishment therein or (ii) the
presentation of a Security of such series (where presentation is required) for
payment on a date more than 30 days after the date on which such payment became
due and payable or the date on which payment thereof is duly provided for,
whichever occurs later;

     (b) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

     (c) any tax, assessment or other governmental charge which is payable
otherwise than by withholding from payments of (or in respect of) principal of,
or any interest on, the Securities of such series;

     (d) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of the
Security of such series (i) to provide information concerning the nationality,
residence or identity of the Holder or such beneficial owner or (ii) to make any
declaration or other similar claim or satisfy any information or reporting
requirements, which, in the case of (i) or (ii), is required or imposed by a
statute, treaty, regulation or administrative practice of the taxing
jurisdiction as a precondition to exemption from all or part of such tax,
assessment or other governmental charge; or

     (e) any combination of items (a), (b), (c) and (d) above; nor shall
additional amounts be paid with respect to any payment of the principal of, or
any interest on, any Security of such series to any Holder who is a fiduciary or
partnership or other than the sole beneficial owner of such payment to the
extent such payment would be required by the laws of the jurisdiction (or any
political subdivision or taxing authority thereof or therein) to be included in
the income for tax purposes of a beneficiary or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such additional amounts had it been the Holder of such
Security.

     The foregoing provisions shall apply mutatis mutandis to any withholding or
deduction for or on account of any present or future taxes, assessments or
governmental charges of whatever nature of any jurisdiction in which any
successor Person to the Guarantor is organized, or any political subdivision or
taxing authority thereof or therein; provided, however, that such payment of
                                     --------  -------
additional amounts may be subject to such further exceptions as may be
established in the terms of such Securities established as contemplated by
Section 301.

     Subject to the foregoing provisions, whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on,

or in respect of, any Security of any series or payment of any related coupon or
the net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of additional
amounts provided for in this Section to the extent that, in such context,
additional amounts are, were or would be payable in respect thereof pursuant to
the provisions of this Section and express mention of the payment of additional
amounts (if applicable) in any provisions hereof shall not be construed as
excluding additional amounts in those provisions hereof where such express
mention is not made.

     If the terms of the Securities of a series established as contemplated by
Section 301 do not specify that additional amounts pursuant to the Section will
not be payable by the Guarantor, at least 10 days prior to the first Interest
Payment Date with respect to that series of Securities (or if the Securities of
that series will not bear interest prior to Maturity, the first day on which a
payment of principal and any premium is made), and at least 10 days prior to
each date of payment of principal and any premium or interest if there has been
any change with respect to the matters set forth in the below-mentioned
Officers' Certificate, the Guarantor will furnish the Trustee and the Company's
principal Paying Agent or Paying Agents, if other than the Trustee, with an
Officers' Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of and any premium or interest on the
Securities of that series or under the related Guarantees shall be made to
Holders of Securities of that series without withholding for or on account of
any tax, assessment or other governmental charge described in the Securities of
that series or the related Guarantees. If any such withholding shall be
required, then such Officers' Certificate shall specify by country the amount,
if any, required to be withheld on such payments to such Holders of Securities
and the Guarantor (only if a payment under said Guarantees is then due) will pay
to the Trustee or such Paying Agent or Paying Agents the additional amounts
required by this Section.

     The Guarantor covenants to indemnify each of the Trustee and any Paying
Agent for, and to hold each of them harmless against, any loss, liability or
expense arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officer's Certificate furnished pursuant to this
Section, except to the extent that any such loss, liability or expense is due to
its own negligence or bad faith.

                            Redemption of Securities

Section 1101.  Applicability of Article.

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

                                       67

Section 1102.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution or in another manner specified as contemplated by Section 301
for such Securities. In case of any redemption at the election of the Company,
the Company shall, at least 45 days prior to 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 Securities of
such series to be redeemed. In the case of any redemption of Securities (a)
prior to the expiration of any restriction on such redemption provided in the
terms of such Securities or elsewhere in this Indenture, or (b) pursuant to an
election of the Company which is subject to a condition specified in the terms
of such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers' Certificate evidencing compliance with such
restriction or condition.

Section 1103.  Selection by Trustee of Securities to Be Redeemed.

     If less than all the Securities of any series are to be redeemed (unless
such redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series not previously
called for redemption, by such method as the Trustee shall deem fair and
appropriate and which may provide for the selection for redemption of portions
(equal to the minimum authorized denomination for Securities of that series or
any integral multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for
Securities of that series.

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

     The provisions of the two preceding paragraphs shall not apply with respect
to any redemption affecting only a single Security, whether such Security is to
be redeemed in whole or in part. In the case of any such redemption in part, the
unredeemed portion of the principal amount of the Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination for such Security).

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

Section 1104.  Notice of Redemption.

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

     All notices of redemption shall state:

                                       68

<PAGE>

          (1) the Redemption Date,

          (2) the Redemption Price or, if not then ascertainable, the manner of
     calculation thereof,

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

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

          (5) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, and

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

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

Section 1105.  Deposit of Redemption Price.

     Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1006) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.

Section 1106.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Record Dates according to their
terms and the provisions of Section 307.

                                       69

<PAGE>

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

Section 1107.  Securities Redeemed in Part.

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security
surrendered; provided, that if a Global Security is so surrendered, such new
Security so issued shall be a new Global Security in a denomination equal to the
unredeemed portion of the principal of the Global Security so surrendered.

Section 1108.  Optional Redemption Due to Changes in Tax Treatment.

With respect to each series of Securities, if, as the result of any change in or
any amendment to the laws of the United Kingdom, or of any political subdivision
or taxing authority thereof or therein, affecting taxation, or any change in an
application or interpretation of such laws either generally or in relation to
any particular series of Securities, which change or amendment to such laws
becomes effective on or after the date specified for such series pursuant to
Section 301(7) or which change in application or interpretation is notified to
the Company or the Guarantor on or after such date, it is determined by the
Company or the Guarantor that the Company or the Guarantor would be required to
make payments or additional amounts (i) in respect of interest on the next
succeeding Interest Payment Date pursuant to the terms of the Guarantees
endorsed on the Securities of such series, as applicable, assuming a payment in
respect of such interest were required to be made pursuant thereto on such
Interest Payment Date, or (ii) in respect of the principal of any series of
Original Issue Discount Securities at the date of such determination pursuant to
the terms of the Guarantees endorsed on the Securities of such series, as
applicable, assuming a payment in respect of such principal were required to be
made pursuant thereto on such date, in either case the Company or the Guarantor
may, at its option, redeem such series of Securities in whole at any time
(except in the case of a series of Securities that has a variable rate of
interest, which may be redeemed on any Interest Payment Date) at a Redemption
Price equal to 100 percent of the principal amount thereof plus accrued interest
to the date fixed for redemption (except in the case of any series of
Outstanding Original Issue Discount Securities which may be redeemed at the
Redemption Price specified by the terms of such series). Prior to any redemption
of such a series of Securities pursuant to this Section, the Company or the
Guarantor shall provide the Trustee with an Opinion of Counsel that the
conditions precedent to the right of the Company or the Guarantor to redeem such
series of Securities pursuant to this Section have occurred. Such Opinion of
Counsel shall be based

                                       70

<PAGE>

on the laws and application and interpretation thereof in effect on the date of
such opinion or to become effective on or before the next succeeding Interest
Payment Date.

                                 ARTICLE TWELVE

                                  Sinking Funds

Section 1201.  Applicability of Article.

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

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

Section 1202.  Satisfaction of Sinking Fund Payments with Securities.

     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been redeemed either at the election of the Company
pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in each
case in satisfaction of all or any part of any sinking fund payment with respect
to the Securities of such series required to be made pursuant to the terms of
such Securities as provided for by the terms of such series, provided, however,
that such Securities have not been previously so credited. Such Securities shall
be received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.

Section 1203.  Redemption of Securities for Sinking Fund.

     Not less than 45 days prior to each sinking fund payment date for any
series of Securities, 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 and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and stating the basis for such credit and that such
Securities have not been previously so credited and will also deliver to the
Trustee any Securities to be so delivered. Not more than 60 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking

                                       71

<PAGE>

fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                                   Guarantees

Section 1301.  Guarantee.

     The Guarantor hereby unconditionally guarantees to each Holder of a
Security of each series authenticated and delivered by the Trustee and to the
Trustee the due and prompt payment of the principal of (and premium, if any) and
interest on such Security and the due and prompt payment of any sinking fund
payments provided for pursuant to the terms of such Security, when and as the
same shall become due and payable, whether at the Stated Maturity, by
declaration of acceleration, call for redemption or otherwise, according to the
terms of such Security and of this Indenture. In case of the failure of the
Company punctually to make any such principal, premium, interest or sinking fund
payment, the Guarantor hereby agrees to cause any such payment to be made
promptly when and as the same shall become due and payable, whether at the
Stated Maturity, by declaration of acceleration, call for redemption or
otherwise, and as if such payment were made by the Company.

     The Guarantor hereby agrees that its obligations hereunder shall be as if
it were principal debtor and not merely surety, and shall be absolute and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of any Security of any series or this
Indenture, any failure to enforce the provisions of any Security of any series
or this Indenture, or any waiver, modification or indulgence granted to the
Company with respect thereto, by the Holder of any Security of any series or the
Trustee, or any other circumstance which may otherwise constitute a legal or
equitable discharge of a surety or guarantor; provided however, that,
notwithstanding the foregoing, no such waiver, modification or indulgence shall,
without the consent of the Guarantor, increase the principal amount of a
Security or the interest rate thereon or increase any premium payable upon
redemption thereof. The Guarantor hereby waives diligence, presentment, demand
of payment, filing of claims with a court in the event of merger or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest or notice with respect to any Security or the indebtedness evidenced
thereby or with respect to any sinking fund payment required pursuant to the
terms of a Security issued under this Indenture and all demands whatsoever, and
covenants that this Guarantee will not be discharged with respect to any
Security except by payment in full of the principal of (and premium, if any) and
interest on such Security. The Guarantees shall constitute guarantees of payment
and not of collection.

                                       72

<PAGE>

Section 1302.  Subrogation.

     The Guarantor shall be subrogated to all rights of the Holder of a Security
against the Company in respect of any amounts paid to such Holder by the
Guarantor pursuant to the provisions of this Guarantee; provided, however, that
the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of
(and premium, if any) and interest on all Securities of the relevant series
shall have been paid in full.

Section 1303.  Execution and Delivery of Guarantees.

     To evidence its guarantee set forth in Section 1301, the Guarantor hereby
agrees to execute the Guarantee in a form established pursuant to Section 205,
to be endorsed on each Security authenticated and delivered by the Trustee. Each
such Guarantee shall be signed manually or by facsimile by a person duly
authorized thereto by Board Resolution of the Guarantor.

     Guarantees bearing the facsimile signature of any individual who was at any
time such an authorized person of the Guarantor shall bind the Guarantor,
notwithstanding that such individual shall have ceased to be such an authorized
person prior to the authentication and delivery of the Securities upon which
such Guarantees are endorsed or was not such an authorized person at the date of
such Securities.

     The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee endorsed
thereon on behalf of the Guarantor.

Section 1304.  Submission to Jurisdiction.

     The Guarantor agrees that any legal suit, action or proceeding arising out
of or based upon the Indenture or the Guarantees may be instituted in any state
or Federal court in the Borough of Manhattan, The City of New York, New York,
United States of America, waives, to the extent it may effectively do so, any
objection which it may have now or hereafter to the laying of the venue of any
such suit, action or proceeding, and irrevocably submits to the jurisdiction of
any such court in any such suit, action or proceeding. The Guarantor has
designated and appointed BP America Inc. (or any successor corporation) as the
Guarantor's authorized agent to accept and acknowledge on its behalf service of
any and all process which may be served in any such suit, action or proceeding
in any such court and agrees that service of process upon said agent at its
office at 667 Madison Avenue, 22nd Floor, New York, New York 10021, attention of
the General Counsel (or at such other address in the Borough of Manhattan, The
City of New York, as the Guarantor may designate by written notice to the
Company and the Trustee), and written notice of said service to the Guarantor,
mailed or delivered to it, at Britannic House, 1 Finsbury Circus, London EC2M
7BA, England, attention of the Secretary (until another address is filed by the
Guarantor with the Trustee), shall be deemed in every respect effective service
of process upon the Guarantor in any such suit, action or proceeding and shall
be taken and held to be valid personal service upon the Guarantor,

                                       73

<PAGE>

whether or not the Guarantor shall then be doing, or at any time shall have
done, business within the State of New York, and any such service of process
shall be of the same force and validity as if service were made upon it
according to the laws governing the validity and requirements of such service in
such State, and waives all claim of error by reason of any such service. Said
designation and appointment shall be irrevocable until the Indenture shall have
been satisfied and discharged in accordance with Article Four. The Guarantor
agrees to take all action as may be necessary to continue the designation and
appointment of BP America Inc. or any successor corporation in full force and
effect so that the Guarantor shall at all times have an agent for service of
process for the above purposes in the Borough of Manhattan, The City of New
York, New York, United States of America.

                                  *   *   *

     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                                       74

<PAGE>

     In Witness Whereof, the Company and the Trustee hereto have caused this
Indenture to be duly executed, and the Guarantor has caused this Indenture to be
signed on its behalf by , its duly appointed attorney, all as of the day and
year first above written.

where it is hereby expressly required, to the Company and the Guarantor. Such
instrument or instruments (and the action embodied therein and evidenced

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

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

anything done, omitted or suffered to be done by the Trustee, the Company or the
Guarantor in reliance thereon, whether or not notation of such action is made
upon such Security.

action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

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

          (1) the Trustee by any Holder or by the Company or by the Guarantor
     shall be sufficient for every purpose hereunder if made, given, furnished
     or filed

<PAGE>

     in writing to or with the Trustee at its Corporate Trust Office, Attention:
     Institutional Trust Services, or

          (2) the Company or the Guarantor by the Trustee or by any Holder shall
     be sufficient for every purpose hereunder (unless otherwise herein

     Company.

Section 106.   Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

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

Section 107.   Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

Section 110.   Separability Clause.

     In case any provision in this Indenture or in the Securities or in the
Guarantees shall be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby.

Section 111.   Benefits of Indenture.

     Nothing in this Indenture or in the Securities or in the Guarantees,
express or implied, shall give to any Person, other than the parties hereto and
their successors hereunder and the Holders, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of the Securities of any series which specifically
states that such provision shall apply in lieu of this Section)) payment of
interest or principal (and premium, if any) need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest

interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be.

subdivision or taxing authority thereof or therein) in which the Company is
incorporated, shall at any time be required by such jurisdiction (or any such
political subdivision or taxing authority) in respect of any amounts to be paid
by the Company of principal of or interest on a Security of any series, then the
Company will pay to the Holder of a Security of such series such additional
amounts as may be necessary in order that the net amounts paid to such Holder of
such Security who, with respect to any such tax, assessment or other
governmental charge, is not resident in such jurisdiction, after such deduction
or withholding, shall be not less than the amounts specified in such Security to
which such Holder is entitled; provided, however, that the Company shall not be
required to make any payment of additional amounts (1) for or on account of any
such tax, assessment or

otherwise than by withholding from payments of (or in respect of) principal of,
or any interest on, the Securities of such series;

     (d) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of the
Security of such series (i) to provide information concerning the nationality,
residence or identity of the Holder or such beneficial owner or (ii) to make any
declaration or other similar claim or satisfy any information or reporting
requirements, which, in the case of (i) or (ii), is required or imposed by a
statute, treaty, regulation or administrative practice of the taxing
jurisdiction as a precondition to exemption from all or part of such tax,
assessment or other governmental charge;

     (e) any tax, assessment or other governmental charge which such Holder
would have been able to avoid by presenting such Security to another Paying
Agent;

payment pursuant to any European Union Directive on the taxation of savings
implementing the conclusions of the ECOFIN Council meeting of November 26 and
27, 2000, or any law implementing such directive; or

     (g) any combination of items (a), (b), (c), (d), (e) and (f) above; nor
shall additional amounts be paid with respect to any payment of the principal
of, or any interest on, any Security of such series to any Holder who is a
fiduciary or partnership or other than the sole beneficial owner of such payment
to the extent such payment would be required by the laws of the jurisdiction (or

principal of this Security shall not bear interest except in the case of a
default in payment of principal upon acceleration, upon redemption or at Stated
Maturity and in such case the overdue principal of this Security shall bear

bear interest at the rate of .......% per annum (to the extent that the payment
of such interest shall be legally enforceable), which shall accrue from the date
of such demand for payment to the date payment of such interest has been made or
duly provided for, and such interest shall also be payable on demand.]

         [Notwithstanding the foregoing, the Company may not, prior to
.............., redeem any Securities of this series as contemplated by [Clause

         In the event of redemption of this Security in part only, a new
Security or Securities of this series for the unredeemed portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

         [If the Security is not subject to redemption, -- This Security is not
redeemable prior to Stated Maturity.]

         [If the Security is not an Original Issue Discount Security, -- If an
Event of Default with respect to Securities of this series shall occur and be

declared due and payable in the manner and with the effect provided in the
Indenture. Such amount shall be equal to -- insert formula for determining the
amount. Upon payment (i) of the amount of principal so declared due and payable
and (ii) of interest on any overdue principal and overdue interest (in each case
to the extent that the payment of such interest shall be legally enforceable),
all of the Company's obligations in respect of the payment of the principal of
and interest, if any, on the Securities of this series shall terminate.]

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the Guarantor and the rights of the Holders of the Securities of
each series to be affected under the Indenture at any time by the Company, the
Guarantor and the Trustee with the consent of the Holders of a majority in
principal amount of the Securities at the time Outstanding of each series to be
affected. The Indenture also contains provisions permitting the Holders of
specified percentages in principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of such series,
to waive compliance by the Company or the Guarantor, or both, with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture

<PAGE>

or for the appointment of a receiver or trustee or for any other remedy
thereunder, unless such Holder shall have previously given the Trustee written
notice of a continuing Event of Default with respect to the Securities of this
series, the Holders of not less than 25% in principal amount of the Securities
of this series at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity, and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities of
this series at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed or provided for herein.

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

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

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

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient in cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,
the Company, the Guarantor, the Trustee and any agent of the Company, the
Guarantor or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes (subject to Section 307 of the
Indenture), whether or not this Security be overdue, and neither the Company,
the Guarantor, the Trustee nor any such agent shall be affected by notice to the
contrary.

         The Indenture provides that the Company and the Guarantor, at the
Guarantor's option, (a) will be discharged from any and all obligations in
respect of the Securities

                                       19

<PAGE>

(except for certain obligations to register the transfer or exchange of
Securities, replace stolen, lost or mutilated Securities, maintain paying
agencies and hold moneys for payment in trust) or (b) need not comply with
certain restrictive covenants of the Indenture, in each case if the Company or
the Guarantor deposits, in trust, with the Trustee money or Government
Obligations which through the payment of interest thereon and principal thereof
in accordance with their terms will provide money, in an amount sufficient to
pay all the principal (including any mandatory sinking fund payments) of, and
(premium, if any) and interest on, the Securities on the dates such payments are
due in accordance with the terms of such Securities and Guarantees, and certain
other conditions are satisfied.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

any political subdivision or taxing authority thereof or therein) to be included
in the income for tax purposes of a beneficiary or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such additional amounts had it been the Holder of such
Security.

     The foregoing provisions shall apply mutatis mutandis to any withholding or
deduction for or on account of any present or future taxes, assessments or
governmental charges of whatever nature of any jurisdiction in which any
successor Person to the Guarantor is organized, or any political subdivision or
taxing authority thereof or therein.

     The Guarantor hereby agrees that its obligations hereunder shall be as if
it were principal debtor and not merely surety, and shall be absolute and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of such Security or such Indenture, any failure
to enforce the provisions of such Security or such Indenture, or any waiver,
modification or indulgence granted to the Company with respect thereto, by the
Holder of such Security or such Trustee, or any other circumstance which may
otherwise constitute a legal or equitable discharge of a surety or guarantor;
provided, however, that, notwithstanding the foregoing, no such waiver,
modification or indulgence shall, without the consent of the Guarantor, increase
the principal amount of such Security or the interest rate thereon or increase
any premium payable upon redemption thereof. The Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger or bankruptcy of the Company, any right to require a proceeding
first against the Company, protest or notice with respect to such Security or
the indebtedness evidenced thereby [or with respect to any sinking fund payment
required under such Security] and all demands whatsoever, and covenants that
this Guarantee will not be discharged except by payment in full of the principal
of (and premium, if any) and interest on such Security. This is a guarantee of
payment and not of collection.

     The Guarantor shall be subrogated to all rights of the Holder of such
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor

                                       22

pursuant to the provisions of this Guarantee; provided, however, that the
Guarantor shall not be entitled to enforce, or to receive any payments arising
out of or based upon, such right of subrogation until the principal of (and
premium, if any) and interest on all Securities of the same series issued under
such Indenture shall have been paid in full.

     No reference herein to such Indenture and no provision of this Guarantee or
of such indenture shall alter or impair the guarantee of the Guarantor, which is
absolute and unconditional, of the due and punctual payment of the principal of
(and premium, if any) and interest on the Security upon which this Guarantee is
endorsed at the times, place and rate, and in the cash or currency prescribed
therein.

     This Guarantee shall not be valid or obligatory for any purpose until the
certificate of authentication of such Security shall have been manually executed
by or on behalf of the Trustee under such Indenture.

     All terms used in this Guarantee which are defined in such Indenture shall
have the meanings assigned to them in such Indenture.

     In Witness Whereof, the Guarantor has caused this Guarantee to be signed
manually or in facsimile by a person duly authorized in that behalf.

                                                                      BP p.l.c.

Section 206.  Form of Legend for Global Securities.

determined pursuant to Section 201:

Security (other than a transfer of this Security as a whole by the Depositary to
a nominee of the Depositary or by a nominee of the Depositary to the Depositary
or another nominee of the Depositary) may be registered except in such limited
circumstances."

<PAGE>

     requisite Holders of such Securities to declare the principal amount
     thereof due and payable pursuant to Section 502;

          (18) with respect to such series of Securities, the "Stated Intervals"
     and the "Record Date" for purposes of Section 312(a) (in the case of
     non-interest bearing Securities) and 316(c), respectively, of the Trust
     Indenture Act;

          (19) if additional amounts pursuant to Section 1010 will not be
     payable by the Company or the Guarantor; and

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

     All Securities of any one series shall be substantially identical except as
to denomination and number and except as may otherwise be provided in or
pursuant to such Board Resolutions and set forth (or determined in the manner
provided in) in such Officers' Certificates or in any such indenture
supplemental hereto.

     If any of the terms of the series are established by action taken pursuant
to a Board Resolution of the Company or the Guarantor, a copy of an appropriate
record of such action shall be certified by the Secretary or an Assistant
Secretary of the Company or by the Secretary, a Deputy Secretary, an Assistant
Secretary or a Deputy Assistant Secretary of the Guarantor, as the case may be,
and delivered to the trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

     With respect to Securities of a series offered in a Periodic Offering, the
Board Resolution (or action taken pursuant thereto), Officers' Certificate or
supplemental indenture referred to above may provide general terms or parameters
for Securities of such series and provide either that the specific terms of
particular Securities of such series shall be specified in a Company Order or
that such terms shall be determined by the Company in accordance with other
procedures specified in a Company Order as contemplated by the third paragraph
of Section 303.

     Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount
of a series of Securities may be increased and additional Securities of such
series may be issued up to the maximum aggregate principal amount authorized
with respect to such series as increased.

Section 302. Denominations.

     The Securities of each series shall be issuable in registered form without
coupons in such denominations as shall be specified as contemplated by Section
301. In the absence of any such provisions with respect to the Securities of any
series, the Securities of such series shall be issuable in denominations of
$1,000 and any integral multiple thereof.

                                       26

Section 303. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by one of its
Directors or senior officers and attested by its Secretary or one of its
Assistant Secretaries. The signature of any of such director or officer on the
Securities may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company having endorsed thereon Guarantees executed by the Guarantor to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that in
                                                      --------  -------
the case of Securities offered in a Periodic Offering, the Trustee shall
authenticate and deliver such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee
of oral or electronic instructions from the Company or its duly authorized
agents, promptly confirmed in writing) acceptable to the Trustee as may be
specified by or pursuant to a Company Order delivered to the Trustee prior to
the time of the first authentication of Securities of such series. If the form
or terms of the Securities of the series or the form of the Guarantees endorsed
thereon have been established by or pursuant to one or more Board Resolutions as
permitted by Sections 201 and 301, in authenticating such Securities, and
accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive, and (subject to 601)
shall be fully protected in relying upon, an Opinion of Counsel stating,

          (a) if the form of such Securities or Guarantees has been established
     by or pursuant to Board Resolution as permitted by Section 201, that such
     form has been established in conformity with the provisions of this
     Indenture;

          (b) if the terms of such Securities have been, or in the case of
     Securities of a series offered in a Periodic Offering, will be, established
     by or pursuant to Board Resolution as permitted by Section 301, that such
     terms have been, or in the case of Securities of a series offered in a
     Periodic Offering, will be, established in conformity with the provisions
     of this Indenture, subject, in the case of Securities of a series offered
     in a Periodic Offering, to any conditions specified in such Opinion of
     Counsel;

          (c) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and

                                       27

<PAGE>

     similar laws of general applicability relating to or affecting creditors'
     rights and to general equity principles, and

          (d) that such Guarantees, when the Securities upon which they shall
     have been endorsed shall have been authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Guarantor enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and similar laws of general applicability
     relating to or affecting creditors' rights and to general equity
     principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities or this Indenture or otherwise in a manner which
is not reasonably acceptable to the Trustee.

     Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

     With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Company and the Guarantor of
any of such Securities and the related Guarantees, the form and terms thereof
and the legality, validity, binding effect and enforceability thereof, upon the
Opinion of Counsel and the other documents delivered pursuant to Sections 201
and 301 and this Section, as applicable, in connection with the first
authentication of Securities of such series.

     Each Security shall be dated the date of its authentication.

     No Security or Guarantee endorsed thereon shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose unless there
appears on such Security a certificate of authentication substantially in the
form provided for herein executed by the Trustee by manual signature of an
authorized officer, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder and that such Security or Guarantee is entitled to the
benefits of this Indenture.

Section 304. Temporary Securities.

     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities substantially of the tenor of the definitive Securities in
lieu of which they are issued, and having endorsed thereon Guarantees duly
executed by the Guarantor

                                       28

<PAGE>

substantially of the tenor of the definitive Guarantees, which Securities and
Guarantees may be printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities and the person duly authorized thereto executing such Guarantees may
determine, all as evidenced by such execution.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series of authorized denominations and of a like
aggregate principal amount and tenor, having endorsed thereon Guarantees duly
executed by the Guarantor. Until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

Section 305. Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office being herein
sometimes referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

     Upon surrender for registration of transfer of any Security of any series
at the office or agency in a Place of Payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like aggregate principal amount
and tenor, each such Security having endorsed thereon a Guarantee duly executed
by the Guarantor.

     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of a
like aggregate principal amount and tenor, each such Security having endorsed
thereon a Guarantee duly executed by the Guarantor, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company and the Guarantor,
evidencing the same

                                       29

<PAGE>

debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

     Every Security presented or surrendered for registration of transfer or for
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.

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

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

     Each Global Security authenticated under this Indenture shall be registered
in the name of the Depositary designated for such Global Security or a nominee
thereof and delivered to such Depositary or a nominee thereof or custodian
therefor, and each such Global Security shall constitute a single Security for
all purposes of this Indenture.

     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any Global Security shall be exchangeable pursuant
to this Section 305 for Securities registered in the names of Persons other than
the Depositary for such series or its nominee if, but only if, (i) such
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such series or at any time ceases to be a clearing agency
registered as such under the Exchange Act, as amended, and the Company and/or
the Guarantor notify the Trustee that they are unable to locate a qualified
successor Depositary, (ii) the Company and/or the Guarantor executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (iii) there shall have occurred and be continuing an Event of
Default with respect to the Securities of such series and beneficial owners of
the Securities evidencing not less than 50% of the aggregate unpaid principal
amount of the Securities of such series advise the Trustee and the Depositary
through participants in writing that the continuation of a book-entry system is
no longer in the best interests of the beneficial owners of the Securities of
such series. Any Global Security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Securities registered in such names as such
Depositary shall direct.

     Notwithstanding any other provision of this Indenture, a Global Security
may not be transferred except as a whole by the Depositary for such Global
Security to a nominee

                                       30

<PAGE>

of such Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary.

Section 306.  Mutilated, Destroyed, Lost and Stolen Securities.

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount, having
endorsed thereon a Guarantee duly executed by the Guarantor, and bearing a
number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount, having endorsed thereon a Guarantee duly executed by the Guarantor, and
bearing a number not contemporaneously Outstanding.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security upon compliance with the
foregoing conditions.

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company and the Guarantor, whether or not the
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued
hereunder.

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

Section 307.  Payment of Interest; Interest Rights Preserved.

     Except as otherwise provided as contemplated by Section 301 with respect to
any series of Securities, interest on any 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 that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

                                       31

<PAGE>

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

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security or such series and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this Clause provided. Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the Trustee of the notice of the proposed payment. The Trustee shall
     promptly notify the Company of such Special Record Date and, in the name
     and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be mailed, first class postage prepaid, to each Holder of Securities of
     such series at his address as it appears in the Security Register, not less
     than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been so mailed, such Defaulted Interest shall be paid to the Persons
     in whose names the Securities of such series (or their respective
     Predecessor Securities) are registered at the close of business on such
     Special Record Date and shall no longer be payable pursuant to the
     following Clause (2).

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

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

Section 308. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the
Company, the Guarantor, the Trustee and any agent of the Company, the Guarantor
or the Trustee may treat the Person in whose name such Security is registered as
the owner of such Security for the purpose of receiving payment of principal of
(and premium, if any) and (subject to Section 307) interest on such Security and
for all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Guarantor, the Trustee nor any agent of the Company,
the Guarantor or the Trustee shall be affected by notice to the contrary.

     No holder of any beneficial interest in any Global Security held on its
behalf by a Depositary shall have any rights under this Indenture with respect
to such Global Security, and such Depositary may be treated by the Company, the
Guarantor, the Trustee, and any agent of the Company, the Guarantor or the
Trustee as the owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall impair, as between a
Depositary and such holders of beneficial interests, the operation of customary
practices governing the exercise of the rights of the Depositary as Holder of
any Security.

     None of the Company, the Guarantor, the Trustee or any agent of the
Company, the Guarantor or the Trustee shall have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests in a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

Section 309. Cancellation.

     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company or the Guarantor may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company or the Guarantor may
have acquired in any manner whatsoever, and may deliver to the Trustee (or to
any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of by
the Trustee in accordance with its customary procedures or as directed by a
Company Order.

Section 310. Computation of Interest.

     Except as otherwise specified as contemplated by Section 301 for Securities
of any series, interest on the Securities of each series shall be computed on
the basis of a 360-day year of twelve 30-day months.

                           Satisfaction and Discharge

Section 401.   Satisfaction and Discharge of Indenture.

     This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

               (1)  either

                    (A) all Securities theretofore authenticated and delivered
               (other than (i) Securities which have been destroyed, lost or
               stolen and which have been replaced or paid as provided in
               Section 306 and (ii) Securities for whose payment money has
               theretofore been deposited in trust or segregated and held in
               trust by the Company or the Guarantor and thereafter repaid to
               the Company or the Guarantor or discharged from such trust, as
               provided in Section 1006) have been delivered to the Trustee for
               cancellation; or

                    (B) all such Securities not theretofore delivered to the
               Trustee for cancellation

                        (i)   have become due and payable, or

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

                        (iii) are to be called for redemption within one year
                    under arrangements satisfactory to the Trustee for the
                    giving of notice of redemption by the Trustee in the name,
                    and at the expense, of the Company,

               and the Company or the Guarantor, in the case of (i), (ii) or
               (iii) above, has deposited or caused to be deposited with the
               Trustee as trust funds in trust for the purpose an amount
               sufficient to pay and discharge the entire indebtedness on such
               Securities not theretofore delivered to the Trustee for
               cancellation, for principal (and premium, if any) and interest to
               the date of such deposit (in the case of Securities which have
               become due and payable) or to the Stated Maturity or Redemption
               Date, as the case may be;

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

                                       34

<PAGE>

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

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company and the Guarantor to the Trustee under Section 607,
the obligations of the Company and the Guarantor to any Authenticating Agent
under Section 614 and, if money shall have been deposited with the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1006 shall survive.

Section 402. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1006, all money
and the proceeds of any Government Obligations deposited with the Trustee
pursuant to Section 401 or 403 shall be held in trust and applied by it, in
accordance with the provisions of the Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company or
the Guarantor acting as Paying Agent) as the Trustee may determine, of the
principal (and premium, if any) and interest to the Holders of the series of
Securities for the payment in respect of which such money has been deposited
with the Trustee.

     The Company or the Guarantor shall pay and indemnify the Trustee against
any tax, fee or other charge imposed on or assessed against the Government
Obligations deposited pursuant to Section 403 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of Outstanding Securities. The
obligations of the Company and the Guarantor pursuant to this paragraph shall be
joint and several.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company or the Guarantor from time to time upon Company
Request any money or Government Obligations held by it as provided in Section
403 with respect to any Securities which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, are in excess of the amount
thereof which would then be required to be deposited to effect the Discharge or
Covenant Defeasance, as the case may be, with respect to such Securities.

Section 403. Defeasance Upon Deposit of Moneys or Government Obligations.

     At the Guarantor's option, either (a) the Company and the Guarantor shall
each be deemed to have been Discharged (as defined below) from its respective
obligations with respect to any series of Securities on the 91st day after the
applicable conditions set forth below have been satisfied or (b) the Company and
the Guarantor shall cease to be under any obligation to comply with any term,
provision or condition set forth in Sections 801 or 802 or any covenant set
forth on any indenture supplemental to this Indenture or otherwise established
pursuant to Section 301, and noncompliance with such Sections or covenants
shall not give rise to any Event of Default

                                       35

<PAGE>

under Section 501(4) ("Covenant Defeasance"), with respect to any series of
Securities at any time after the applicable conditions set forth below have been
satisfied:

          (1) the Company or the Guarantor shall have deposited or caused to be
     deposited irrevocably with the Trustee or its agent as trust funds in
     trust, specifically pledged as security for, and dedicated solely to, the
     benefit of the Holders of the Securities of such series (i) money in an
     amount, or (ii) Government Obligations of the government in the currency of
     which the Securities of such series are denominated which through the
     payment of interest and principal in respect thereof in accordance with
     their terms will provide, not later than 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 (ii) and (iii)) 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 mandatory sinking fund payments) of and interest on,
     the outstanding Securities of such series on the dates such installments of
     interest or principal are due or to and including the Redemption Date
     irrevocably designated by the Guarantor pursuant to subparagraph (5)
     hereof;

          (2) if the Securities of such series are then listed on the New York
     Stock Exchange, the Company or the Guarantor shall have delivered to the
     Trustee an Opinion of Counsel to the effect that the exercise of the option
     under this Section 403 would not cause such Securities to be delisted;

          (3) no Event of Default or event which with notice or lapse of time
     would become an Event of Default under Section 501(1), (2), (3), (5), (6)
     or (7) with respect to the Securities of such series shall have occurred
     and be continuing on the date of such deposit;

          (4) the Company or the Guarantor shall have delivered to the Trustee
     an Opinion of Counsel to the effect that holders of the Securities of such
     series will not recognize income, gain or loss for Federal income tax
     purposes as a result of the exercise of the option under this Section 403
     and will be subject to Federal income tax on the same amount and in the
     same manner and at the same times as would have been the case if such
     option had not been exercised, and, in the case of Securities being
     Discharged, such opinion shall be accompanied by a private letter ruling to
     that effect received from the United States Internal Revenue Service or a
     revenue ruling pertaining to a comparable form of transaction to that
     effect published by the United States Internal Revenue Service;

          (5) if the Company or the Guarantor has deposited or caused to be
     deposited money or Government Obligations to pay or discharge the principal
     of (and premium, if any) and interest on the Outstanding Securities of a
     series to and including a Redemption Date pursuant to subparagraph (1)
     hereof, such Redemption Date shall be irrevocably designated by a Board
     Resolution delivered to the Trustee on or prior to the date of deposit of
     such money or Government Obligations and such Board Resolution shall be
     accompanied by an irrevocable

                                       36

<PAGE>

     Company Request that the Trustee give notice of such redemption in the name
     and at the expense of the Company not less than 30 nor more than 60 days
     prior to such Redemption Date in accordance with Section 1104; and

          (6) the Company or the Guarantor shall have delivered to the Trustee
     an Officers' Certificate and an Opinion of Counsel, each stating that all
     conditions precedent with respect to such Discharge or Covenant Defeasance
     have been complied with.

"Discharged" means that the Company and Guarantor shall be deemed to have paid
and discharged the entire indebtedness represented by, and obligations under,
the Securities of such series and the Guarantees endorsed thereon and to have
satisfied all the obligations under this Indenture relating to the Securities of
such series and the Guarantees endorsed thereon (and the Trustee, at the expense
of the Company, shall execute proper instruments acknowledging the same), except
(A) the rights of holders of Securities of such series to receive, from the
trust fund described in clause (1) above payment of the principal of and the
interest on such Securities when such payments are due; (B) the Company's or the
Guarantor's obligations, as the case may be, with respect to such Securities
under Sections 305, 306, 1002, 1005 and 1006; and (C) the rights, powers,
trusts, duties and immunities of the Trustee hereunder.

     Notwithstanding any Covenant Defeasance with respect to Sections 801 and
802, any corporation or Person that would otherwise have been required to assume
the obligations of the Company or the Guarantor pursuant to said Sections shall
be required, as a condition to any merger, consolidation, amalgamation,
transfer, conveyance or lease contemplated thereby, to assume the obligations of
the Company or the Guarantor, as the case may be, to the Trustee under Sections
402 and 607.

     or order adjudging the Company or the Guarantor a bankrupt or insolvent, or
     approving as properly filed a petition filed against the Company or the

     the United Kingdom, or appointing without the consent of the Company or the
     Guarantor a custodian, receiver, liquidator, assignee, trustee, sequestrate

     case or proceeding against it, or the filing by it of a petition or answer
     or consent seeking reorganization or relief under any applicable

                                       38

<PAGE>

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

     Upon receipt by the Trustee of any Notice of Default pursuant to this
Section 501, (i) with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established, which
record date shall be at the close of business on the day the Trustee receives
such Notice of Default, and (ii) with respect to any other series of Securities,
the Trustee may, but shall not be obligated to, establish a record date, in each
case for the purpose of determining Holders of Outstanding Securities of such
series entitled to join in such Notice of Default. If such record date is fixed,
the Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such Notice of Default, whether or not
such Holders remain Holders after such record date; provided, however, that
unless Holders of at least the requisite principal amount (which amount shall be
25% in the case of subclause (4) of this Section) of the Outstanding Securities
of such series, or their proxies, shall have joined in such Notice of Default
prior to the day which is 90 days after such record date, such Notice of Default
and the Act of Holders, or their proxies, joining in such Notice of Default
shall automatically and without further action by any Holders be cancelled and
of no effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a
Holder, from giving, (i) after expiration of such 90-day period, a new Notice of
Default to the same effect as that cancelled pursuant to the proviso to the
preceding sentence, or (ii) during any such 90-day period in respect of any
Notice of Default with respect to a prospective Event of Default with respect to
Securities of such series, an additional Notice of Default with respect to any
other prospective Event of Default (other than a prospective Event of Default as
to which such a 90-day period has not expired) with respect to Securities of
such series, in either of which events a new record date shall or may, as the
case may be, be established pursuant to the provisions of this Section 501 in
respect of such new or additional Notice of Default.

Section 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount (or, if the Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities
of that series to be due and payable immediately, by a notice in writing to the
Company and the Guarantor (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.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company, the
Guarantor and the Trustee, may rescind and annul such declaration and its
consequences if

                                       39

<PAGE>

          (1)  the Company or the Guarantor has paid or deposited with the
     Trustee a sum sufficient to pay

               (A) all overdue interest on all Securities of that series,

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

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

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

     and

          (2)  all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

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

     Upon receipt by the Trustee of any written notice declaring such an
acceleration, or rescission and annulment thereof, (i) with respect to
Securities of a series all or part of which is represented by a Global Security,
a record date shall be established, which record date shall be at the close of
business on the day the Trustee receives such notice, and (ii) with respect to
any other series of Securities, the Trustee may, but shall not be. obligated to,
establish a record date, in each case for the purpose of determining Holders of
Outstanding Securities of such series entitled to join in such notice. If such
record date is fixed, the Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such Holders remain Holders after such record date; provided,
however, that unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, and the Act of Holders, or their
proxies, joining in such notice shall automatically and without further action
by any Holders be cancelled and of no effect. Nothing in this paragraph shall
prevent a Holder, or a proxy of a Holder, of Securities of any series from
giving, (i) after expiration of such 90-day period, a new written notice of
declaration of acceleration, or rescission and annulment thereof, as the case
may be, to the same effect as that cancelled pursuant to the proviso to the
preceding sentence, or (ii) during any such 90-day period in respect of any
written

                                       40

<PAGE>

notice of declaration of acceleration or rescission and annulment thereof, as
the case may be, with respect to any Event of Default with respect to Securities
of such series, an additional written notice of declaration of acceleration, or
rescission and annulment thereof, as the case may be, with respect to any other
Event of Default (other than an Event of Default as to which such a 90-day
period has not expired) with respect to Securities of such series, in either of
which events a new record date shall or may, as the case may be, be established
pursuant to the provisions of this Section 502 in respect of such new or
additional written notice.

Section 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
or rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company, the Guarantor or any other obligor upon such Securities and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company, the Guarantor or any other obligor upon
such Securities, wherever situated.

     If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

Section 504.  Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Company, the Guarantor of any other
obligor upon the Securities or the property of the Company, the Guarantor or of
such other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee shall
have made any demand on the Company or the Guarantor for the payment of overdue
principal or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act in order to have claims of the Holders and the Trustee allowed in
any such proceeding. In particular, the Trustee shall be authorized,

          (i)  to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     in accordance with the terms thereof and to file such other papers or
     documents as may be necessary or advisable in order to have the claims of

     disbursements and advances of the Trustee, its agents and counsel) and of
     the Holders allowed in such judicial proceeding, and

          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrate or other
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

     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 Securities
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.

Section 505.  Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities 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

                                       42

of which such judgment has been recovered.

     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

              First:  To the payment of all amounts due the Trustee under
     Section 607; and

              Second: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest on the Securities in
     respect of which or for the benefit of which such money has been collected,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on such Securities for principal (and premium, if
     any) and interest, respectively.

Section 507.  Limitation on Suits.

     No Holder of any Security 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 the Securities of that
     series;

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

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

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

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

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek

                                       43

<PAGE>

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.

Section 508.  Unconditional Right of Holders to Receive Principal, Premium and
Interest.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 307)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

Section 509.  Restoration of Rights and Remedies.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company and the Guarantor shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

Section 510.  Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

Section 511.  Delay or Omission Not Waiver.

     No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

Section 512.  Control by Holders.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any

                                       44

<PAGE>

proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee, with respect to the Securities of such series,
provided that

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

          (2)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction, and

          (3)  subject to the provisions of Section 601, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the proceeding so directed would involve the Trustee in personal
     liability.

     Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, (i) with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established, which
record date shall be at the close of business on the day the Trustee receives
such notice, and (ii) with respect to any other series of Securities, the
Trustee may, but shall not be obligated to, establish a record date, in each
case for the purpose of determining Holders of Outstanding Securities of such
series entitled to join in such notice. If such record date is fixed, the
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such notice, whether or not such Holders
remain Holders after such record date; provided, however, that unless the
Holders of not less than a majority in principal amount of the Outstanding
Securities of such series shall have joined in such notice prior to the date
which is 90 days after such record date, such notice and the Act of Holders, or
their proxies, joining in such notice shall automatically and without further
action by any Holders be cancelled and of no effect. Nothing in this paragraph
shall prevent a Holder, or a proxy of a Holder, from giving, (i) after
expiration of such 90-day period, a new notice to the same effect as that
cancelled pursuant to the proviso to the preceding sentence, or (ii) during any
such 90-day period in respect of any notice, a new notice giving directions
contrary to or otherwise different from such notice in either of which events a
new record date shall or may, as the case may be, be established pursuant to the
provisions of this Section 512 in respect of such new notice.

Section 513.  Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

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

                                       45

<PAGE>

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

     With respect to any series of Securities, the Company may, but shall not be
obligated to, establish a record date for the purpose of determining the Persons
entitled to waive any past default hereunder. If a record date is fixed, the
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to waive any default hereunder, whether or not such
Holders remain Holders after such record date; provided, however, that unless
such Holders of not less than a majority in principal amount of the Outstanding
Securities of such series shall have waived such default prior to the date which
is 90 days after such record date, any such waiver previously given shall
automatically and without further action by any Holder be cancelled and of no
effect.

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

Section 514. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, in the manner and to the extent provided
in the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company,
the Guarantor or the Trustee.

Section 515. Waiver of Stay or Extension Laws.

     The Company and the Guarantor each covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company and
the Guarantor each (to the extent that it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law and covenants that it will not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

                                   The Trustee

Section 601. Certain Duties and Responsibilities.

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

Section 602. Notice of Defaults.

     Within 90 days after the occurrence known to the Trustee of any default
hereunder with respect to the Securities of any series, the Trustee shall
transmit by mail to all Holders of Securities of such series, as their names and
addresses appear in the Security Register, notice of all such defaults
hereunder, unless such default shall have been cured or waived provided,
however, that, except in the case of a default in the payment of the principal
of (or premium, if any) or interest on any Security of such series or in the
payment of any sinking fund installment with respect to Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of
directors or Responsible Officers of the Trustee in good faith determine that
the withholding of such notice is in the interest of the Holders of Securities
of such series; and provided, further, that, in the case of any default of the
character specified in Section 501(4) with respect to Securities of such series,
no such notice to Holders shall be given until at least 30 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 Securities of such series.

Section 603. Certain Rights of Trustee.

     Subject to the provisions of Section 601:

          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document 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 or the Guarantor mentioned
     herein shall be sufficiently evidenced by a Company Request or

<PAGE>

     Company Order and any resolution of the Board of Directors of the Company
     or the Guarantor shall be sufficiently evidenced by a Board Resolution;

          (c) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (d) the Trustee may consult with counsel and the written advice of
     such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or
     omitted by it hereunder in good faith and in reliance thereon;

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

          (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, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the relevant books, records and premises of
     the Company and the Guarantor, personally or by agent or attorney; and

          (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
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder.

Section 604. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company
or the Guarantor, and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. The Trustee
or any Authenticating Agent shall not be accountable for the use or application
by the Company of Securities or the proceeds thereof.

                                       48

<PAGE>

Section 605. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company or the Guarantor, in its individual
or any other capacity, may become the owner or pledgee of Securities and,
subject to Sections 608 and 613, may otherwise deal with the Company and the
Guarantor with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

Section 606. Money Held in Trust.

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company or the Guarantor, as the case may be.

Section 607. Compensation and Reimbursement.

     The Company and the Guarantor agree

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

          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel), except any such expense,
     disbursement or advance as may be attributable to its negligence or bad
     faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts hereunder, including the costs and expenses of
     defending itself against (but not of instituting) any claim or liability in
     connection with the exercise or performance of any of its powers or duties
     hereunder.

     As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
such Securities.

<PAGE>

     The obligations of the Company and the Guarantor under this Section shall
be joint and several.

     The provisions of this Section shall survive the satisfaction and discharge
of this Indenture.

Section 608. Disqualification; Conflicting Interests.

     If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall, as soon as practicable
and in any event within 90 days after ascertaining that it has such conflicting
interest, and if the Event of Default (as defined in Section 501 hereof) to
which such conflicting interest relates has not been cured or duly waived or
otherwise eliminated before the end of such 90-day period, either eliminate such
conflicting interest or resign to the extent and in the manner provided by, and
subject to the provisions of, the Trust Indenture Act and this Indenture. To the
extent permitted by such Act, the Trustee shall not be deemed to have a
conflicting interest by virtue of being a trustee under this Indenture with
respect to Securities of more than one series or by virtue of being a trustee
under this Indenture and under any indenture listed in Annex A hereto.

Section 609. Corporate Trustee Required; Eligibility.

     There shall at all times be one and only one Trustee hereunder with respect
to the Securities of each series, which may be a Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, and has a combined
capital and surplus of at least $50,000,000, subject to supervision or
examination by Federal or state authority. If such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section and to
the extent permitted by the Trust Indenture Act, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

Section 610. Resignation and Removal; Appointment of Successor.

     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of

                                       50

<PAGE>

acceptance by a successor Trustee required by Section 611 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
Securities of such series.

     (c)  In accordance with the requirements of Section 315(e) of the Trust
Indenture Act, the Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company and the Guarantor.

     (d)  If at any time:

          (1) the Trustee shall fail to comply with Section 608 after written
     request therefor by the Company or the Guarantor or by any Holder who has
     been a bona fide Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 609 and shall
     fail to resign after written request therefor by the Company or the
     Guarantor 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 a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, subject to the requirements of the Trust Indenture Act on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee with respect to all Securities and the
appointment of a successor Trustee or Trustees.

     (e)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the Guarantor and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 611,
become the successor Trustee with respect to the Securities of such series and
to that extent supersede the successor Trustee appointed by

the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

Section 611. Acceptance of Appointment by Successor.

     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company, the Guarantor 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 the request of the Company, the Guarantor 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.

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

                                       52

<PAGE>

execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein
and each such successor Trustee, without any further act, deed or conveyance,
shall become vested with all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates; but, on request of the
Company and the Guarantor or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

     (c) Upon request of any such successor Trustee, the Company and the
Guarantor 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 the
requirements of the Trust Indenture Act.

Section 612. Merger, Consolidation or Succession to Business.

     Any corporation into which the Trustee may be merged or with which it may
be consolidated, or any corporation resulting from any merger or consolidation
to which the Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder, provided such corporation shall be otherwise
qualified under the requirements of the Trust Indenture Act and eligible under
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

Section 613. Preferential Collection of Claims Against Company.

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

Section 614. Appointment of Authenticating Agent.

     At any time when any of the Securities remain Outstanding the Trustee may
appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon exchange, registration of
transfer or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes

                                       53

<PAGE>

as if authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any state thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or state 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 the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

     The Company and the Guarantor agree to pay to each Authenticating Agent
from time to time reasonable compensation for its services under this Section.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the

                                       54

<PAGE>

Trustee's certificate of authentication, an alternate certificate of
authentication in the following form:

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

     without the consent of the Holder of each Outstanding Security affected
     thereby, provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1009, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611(b) and 901(8), or

          (4) change in any manner adverse to the interests of the Holders of
     Securities the terms and conditions of the obligations of the Guarantor in
     respect of the due and prompt payment of the principal thereof (and
     premium, if any) and interest thereon or any sinking fund payments provided
     in respect thereof.

     A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

     With respect to any series of Securities, the Company may, but shall not be
obligated to, establish a record date for the purpose of determining the Persons
entitled to consent to any indenture supplemental hereto. If a record date is
fixed, the Holders on such record date, or their duly designated proxies, and
only such Persons, shall be entitled

                                       61

<PAGE>

to consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; provided, however, that unless such consent
shall have become effective by virtue of the requisite percentage having been
obtained prior to the date which is 90 days after such record date, any such
consent previously given shall automatically and without further action by any
Holder be cancelled and of no effect.

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

Section 903. Execution of Supplemental Indentures.

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

Section 904. Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

Section 905. Conformity with Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

Section 906. Reference in Securities to Supplemental Indentures.

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company and the Guarantor
shall so determine, new Securities of any series so modified as to conform, in
the opinion of the Trustee, the Company and the Guarantor, to any such
supplemental Indenture may be prepared and executed by the Company, the
Guarantees endorsed thereon may be executed by the Guarantor and such Securities
may be authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

                                  ARTICLE TEN

                  Particular Covenants of Company and Guarantor

Section 1001. Payment of Principal, Premium and Interest by Company.

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture.

Section 1002. Maintenance of Office or Agency by Company.

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes or where such notices or demands may be
served and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

Section 1003. Reserved.

Section 1004. Reserved.

Section 1005. Maintenance of Office or Agency by Guarantor.

     The Guarantor will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment under the Guarantees endorsed thereon and where
notices and demands to or upon the Guarantor in respect of the Guarantees
endorsed on the Securities of that series and this Indenture may be served. The
Guarantor will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the
Guarantor shall fail to maintain any such required office or agency or shall
fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and

                                       63

<PAGE>

demands may be made or served at the Corporate Trust Office of the Trustee, and
the Guarantor hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     The Guarantor may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for such purpose or where such notices or demands may be served
and may from time to time rescind such designations; provided, however, that no
such designation or rescission shall in any manner relieve the Guarantor of its
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Guarantor will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

Section 1006. Money for Securities Payments to Be Held in Trust.

     If the Company or the Guarantor shall at any time act as Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of that
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 for any series of
Securities, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held as provided by the Trust Indenture Act, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

     The Company will cause each Paying Agent for any series of 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:

          (i) comply with the provisions of the Trust Indenture Act applicable
       to it as a Paying Agent and

          (ii) during the continuance of any such default by the Company
     (or any other obligor on the Securities of that series) in the making of
     any payment in respect of the Securities of that series, upon the written
     request of the Trustee, forthwith pay to the Trustee all sums held in trust
     by such Paying Agent for payment in respect of the Securities of such
     series.

     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

                                       64

<PAGE>

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 or the Guarantor, in trust for the payment of the principal of (and
premium, if any) or interest on any 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 be paid to the Company or the Guarantor, as the
case may be, on Company Request, or (if then held by the Company or the
Guarantor) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company and
the Guarantor 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
or the Guarantor as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, The City of
New York, New York, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to the Company or the Guarantor, as the case may be.

Section 1007. Corporate Existence.

     Subject to Article Eight, the Company and the Guarantor will preserve and
keep in full force and effect their respective corporate existences.

Section 1008. Statement by Executive Officers as to Compliance.

     The Company and the Guarantor will each deliver to the Trustee, within 120
days after the end of each fiscal year of the Guarantor ending after the date
hereof, an Executive Officer's Certificate (which need not comply with the
requirements of Section 102), stating whether or not to the best knowledge of
the signers thereof the Company or the Guarantor, as the case may be, has
complied with all conditions and covenants on their part contained in this
Indenture, and if such signers have obtained knowledge of any default by the
Company or the Guarantor in the performance, observance or fulfillment of any
such condition or covenant, specifying all such defaults and the nature and
status thereof of which they may have knowledge. For the purpose of this Section
1008, such compliance with the terms, conditions and covenants of the Indenture
shall be determined without regard to any period of grace or requirement of
notice provided hereunder.

Section 1009. Waiver of Certain Covenants.

     The Company and the Guarantor may omit in any particular instance to comply
with any term, provision or condition set forth in any covenant set forth in any
indenture supplemental to this Indenture or otherwise established pursuant to
Section 301 with respect to the Securities of any series or the Guarantees
endorsed thereon if before the time for such compliance the Holders of at

                                       65

<PAGE>

least a majority in principal amount of the Outstanding 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 so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the Guarantor and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

         With respect to any series of Securities, the Company may, but shall
not be obligated to, establish a record date for the purpose of determining the
Persons entitled to waive any such term, provision or condition. If a record
date is fixed, the Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to waive any such term,
provision or condition hereunder, whether or not such Holders remain Holders
after such record date; provided, however, that unless the Holders of at least a
majority in principal amount of the Outstanding Securities of such series shall
have waived such term, provision or condition prior to the date which is 90 days
after such record date, any such waiver previously given shall automatically and
without further action by any Holder be cancelled and of no effect.

Section 1010. Additional Amounts.

         Unless otherwise specified in any Board Resolution of the Company or
the Guarantor establishing the terms of Securities of a series or the Guarantees
relating thereto in accordance with Section 301, if any deduction or withholding
for any present or future taxes, assessments or other governmental charges of
the jurisdiction (or any political subdivision or taxing authority thereof or
therein) in which the Company or the Guarantor is incorporated, shall at any
time be required by such jurisdiction (or any such political subdivision or
taxing authority) in respect of any amounts to be paid by the Company of
principal of or interest on a Security of any series, or by the Guarantor under
the Guarantees, the Company or the Guarantor, as the case may be, will pay to
the Holder of a Security of such series such additional amounts as may be
necessary in order that the net amounts paid to such Holder of such Security
who, with respect to any such tax, assessment or other governmental charge, is
not resident in such jurisdiction, after such deduction or withholding, shall be
not less than the amounts specified in such Security to which such Holder is
entitled; provided, however, that the Company or the Guarantor, as the case may
be, shall not be required to make any payment of additional amounts (1) for or
on account of any such tax, assessment or governmental charge imposed by the
United States or any political subdivision or taxing authority thereof or
therein or (2) for or on account of:

         (a) any tax, assessment or other governmental charge which would not
have been imposed but for (i) the existence of any present or former connection
between such Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of a power over, such Holder, if such Holder is an
estate, trust, partnership or corporation) and the taxing jurisdiction or any
political subdivision or territory or possession thereof or area subject to its
jurisdiction, including, without limitation, such Holder (or such fiduciary,
settlor, beneficiary, member, shareholder or possessor) being

                                       66

<PAGE>

or having been a citizen or resident thereof or being or having been present or
engaged in trade or business therein or having or having had a permanent
establishment therein or (ii) the presentation of a Security of such series
(where presentation is required) for payment on a date more than 30 days after
the date on which such payment became due and payable or the date on which
payment thereof is duly provided for, whichever occurs later;

         (b) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

         (c) any tax, assessment or other governmental charge which is payable
otherwise than by withholding from payments of (or in respect of) principal of,
or any interest on, the Securities of such series;

         (d) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of the
Security of such series (i) to provide information concerning the nationality,
residence or identity of the Holder or such beneficial owner or (ii) to make any
declaration or other similar claim or satisfy any information or reporting
requirements, which, in the case of (i) or (ii), is required or imposed by a
statute, treaty, regulation or administrative practice of the taxing
jurisdiction as a precondition to exemption from all or part of such tax,
assessment or other governmental charge;

         (e) any tax, assessment or other governmental charge which such Holder
would have been able to avoid by presenting such Security to another Paying
Agent;

         (f) any tax, assessment or other governmental charge which is imposed
on a payment pursuant to any European Union Directive on the taxation of savings
implementing the conclusions of the ECOFIN Council meeting of November 26 and
27, 2000, or any law implementing such directive; or

         (g) any combination of items (a), (b), (c), (d), (e) and (f) above; nor
shall additional amounts be paid with respect to any payment of the principal
of, or any interest on, any Security of such series to any Holder who is a
fiduciary or partnership or other than the sole beneficial owner of such payment
to the extent such payment would be required by the laws of the jurisdiction (or
any political subdivision or taxing authority thereof or therein) to be included
in the income for tax purposes of a beneficiary or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such additional amounts had it been the Holder of such
Security.

         The foregoing provisions shall apply mutatis mutandis to any
withholding or deduction for or on account of any present or future taxes,
assessments or governmental charges of whatever nature of any jurisdiction in
which any successor Person to the Company or the Guarantor, as the case may be,
is organized, or any political subdivision or taxing authority thereof or
therein; provided, however, that such payment of
         --------  -------

                                       67

<PAGE>

additional amounts may be subject to such further exceptions as may be
established in the terms of such Securities established as contemplated by
Section 301.

      Subject to the foregoing provisions, whenever in this Indenture there
is mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or payment of any
related coupon or the net proceeds received on the sale or exchange of any
Security of any series, such mention shall be deemed to include mention of the
payment of additional amounts provided for in this Section to the extent that,
in such context, additional amounts are, were or would be payable in respect
thereof pursuant to the provisions of this Section and express mention of the
payment of additional amounts (if applicable) in any provisions hereof shall not
be construed as excluding additional amounts in those provisions hereof where
such express mention is not made.

      If the terms of the Securities of a series established as contemplated by
Section 301 do not specify that additional amounts pursuant to the Section will
not be payable by the Company or the Guarantor, at least 10 days prior to the
first Interest Payment Date with respect to that series of Securities (or if the
Securities of that series will not bear interest prior to Maturity, the first
day on which a payment of principal and any premium is made), and at least 10
days prior to each date of payment of principal and any premium or interest if
there has been any change with respect to the matters set forth in the
below-mentioned Officers' Certificate, the Company or the Guarantor will furnish
the Trustee and the Company's principal Paying Agent or Paying Agents, if other
than the Trustee, with an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal of and any
premium or interest on the Securities of that series or under the related
Guarantees shall be made to Holders of Securities of that series or any related
coupons without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of that series or the related
Guarantees. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities and the Company or the Guarantor
(only if a payment under said Guarantees is then due), as the case may be, will
pay to the Trustee or such Paying Agent or Paying Agents the additional amounts
required by this Section.

      Each of the Company and the Guarantor covenants to indemnify each of
the Trustee and any Paying Agent for, and to hold each of them harmless against,
any loss, liability or expense arising out of or in connection with actions
taken or omitted by any of them in reliance on any Officer's Certificate
furnished pursuant to this Section, except to the extent that any such loss,
liability or expense is due to its own negligence or bad faith.

                                 ARTICLE ELEVEN

                            Redemption of Securities

Section 1101. Applicability of Article.

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

Section 1102. Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company, the Company shall, at least 45 days prior to 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
Securities of such series to be redeemed. In the case of any redemption of
Securities (a) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (b)
pursuant to an election of the Company which is subject to a condition specified
in the terms of such Securities or elsewhere in this Indenture, the Company
shall furnish the Trustee with an Officers' Certificate evidencing compliance
with such restriction or condition.

Section 1103. Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

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

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination for such Security).

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any

                                       69

<PAGE>

Securities redeemed or to be redeemed only in part, to the portion of the
principal amount of such Securities which has been or is to be redeemed.

Section 1104. Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall state:

                (1)   the Redemption Date,

                (2)   the Redemption Price or, if not then ascertainable, the
         manner of calculation thereof,

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

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

                (5)   the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and

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

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

Section 1105. Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1006) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

Section 1106. Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption

                                       70

<PAGE>

Price therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest. Upon surrender of any such Security for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 307.

         If any 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 Security.

Section 1107. Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security
surrendered; provided, that if a Global Security is so surrendered, such new
Security so issued shall be a new Global Security in a denomination equal to the
unredeemed portion of the principal of the Global Security so surrendered.

Section 1108. Optional Redemption Due to Changes in Tax Treatment.

With respect to each series of Securities, if, as the result of any change in or
any amendment to the laws of the United Kingdom, or of any political subdivision
or taxing authority thereof or therein, affecting taxation, or any change in an
application or interpretation of such laws either generally or in relation to
any particular series of Securities, which change or amendment to such laws
becomes effective on or after the date specified for such series pursuant to
Section 301(7) or which change in application or interpretation is notified to
the Company or the Guarantor on or after such date, it is determined by the
Company or the Guarantor that the Company or the Guarantor would be required to
make payments of additional amounts (i) in respect of interest on the next
succeeding Interest Payment Date pursuant to the terms of the Securities or the
Guarantees endorsed on the Securities of such series, as applicable, assuming a
payment in respect of such interest were required to be made pursuant thereto on
such Interest Payment Date, or (ii) in respect of the principal of any series of
Original Issue Discount Securities at the date of such determination pursuant to
the terms of the Securities or the Guarantees endorsed on the Securities of such
series, as applicable, assuming a payment in respect of such principal were
required to be made pursuant thereto on such date, in either case the Company or
the Guarantor may, at its option, redeem such series of Securities in whole at
any time (except in the

                                       71

case of a series of Securities that has a variable rate of interest, which may
be redeemed on any Interest Payment Date) at a Redemption Price equal to 100
percent of the principal amount thereof plus accrued interest to the date fixed
for redemption (except in the case of any series of Outstanding Original Issue
Discount Securities which may be redeemed at the Redemption Price specified by
the terms of such series). Prior to any redemption of such a series of
Securities pursuant to this Section, the Company or the Guarantor shall provide
the Trustee with an Opinion of Counsel that the conditions precedent to the
right of the Company or the Guarantor to redeem such series of Securities
pursuant to this Section have occurred. Such Opinion of Counsel shall be based
on the laws and application and interpretation thereof in effect on the date of
such opinion or to become effective on or before the next succeeding Interest
Payment Date.

                                 ARTICLE TWELVE

                                  Sinking Funds

Section 1201. Applicability of Article.

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

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

Section 1202. Satisfaction of Sinking Fund Payments with Securities.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series, provided, however, that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

Section 1203. Redemption of Securities for Sinking Fund.

         Not less than 45 days prior to each sinking fund payment date for any
series of Securities, 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 and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and stating the basis for such credit and that such
Securities have not been previously so credited and will also deliver to the
Trustee any Securities to be so delivered. Not more than 60 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
1103 and cause notice of the redemption thereof to be given in the name of and
at the expense of the Company in the manner provided in Section 1104. Such
notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                                   Guarantees

Section 1301. Guarantee.

         The Guarantor hereby unconditionally guarantees to each Holder of a
Security of each series authenticated and delivered by the Trustee and to the
Trustee the due and prompt payment of the principal of (and premium, if any) and
interest on such Security and the due and prompt payment of any sinking fund
payments provided for pursuant to the terms of such Security, when and as the
same shall become due and payable, whether at the Stated Maturity, by
declaration of acceleration, call for redemption or otherwise, according to the
terms of such Security and of this Indenture. In case of the failure of the
Company punctually to make any such principal, premium, interest or sinking fund
payment, the Guarantor hereby agrees to cause any such payment to be made
promptly when and as the same shall become due and payable, whether at the
Stated Maturity, by declaration of acceleration, call for redemption or
otherwise, and as if such payment were made by the Company.

         The Guarantor hereby agrees that its obligations hereunder shall be as
if it were principal debtor and not merely surety, and shall be absolute and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of any Security of any series or this
Indenture, any failure to enforce the provisions of any Security of any series
or this Indenture, or any waiver, modification or indulgence granted to the
Company with respect thereto, by the Holder of any Security of any series or the
Trustee, or any other circumstance which may otherwise constitute a legal or
equitable discharge of a surety or guarantor; provided however, that,
notwithstanding the foregoing, no such waiver, modification or indulgence shall,
without the consent of the Guarantor, increase the principal amount of a
Security or the interest rate thereon or increase any premium payable upon
redemption thereof. The Guarantor hereby waives

                                       73

<PAGE>

diligence, presentment, demand of payment, filing of claims with a court in the
event of merger or bankruptcy of the Company, any right to require a proceeding
first against the Company, protest or notice with respect to any Security or the
indebtedness evidenced thereby or with respect to any sinking fund payment
required pursuant to the terms of a Security issued under this Indenture and all
demands whatsoever, and covenants that this Guarantee will not be discharged
with respect to any Security except by payment in full of the principal of (and
premium, if any) and interest on such Security. The Guarantees shall constitute
guarantees of payment and not of collection.

Section 1302. Subrogation.

         The Guarantor shall be subrogated to all rights of the Holder of a
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor pursuant to the provisions of this Guarantee; provided, however,
that the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of
(and premium, if any) and interest on all Securities of the relevant series
shall have been paid in full.

Section 1303. Execution and Delivery of Guarantees.

         To evidence its guarantee set forth in Section 1301, the Guarantor
hereby agrees to execute the Guarantee in a form established pursuant to Section
205, to be endorsed on each Security authenticated and delivered by the Trustee.
Each such Guarantee shall be signed manually or by facsimile by a person duly
authorized thereto by Board Resolution of the Guarantor.

         Guarantees bearing the facsimile signature of any individual who was at
any time such an authorized person of the Guarantor shall bind the Guarantor,
notwithstanding that such individual shall have ceased to be such an authorized
person prior to the authentication and delivery of the Securities upon which
such Guarantees are endorsed or was not such an authorized person at the date of
such Securities.

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee endorsed
thereon on behalf of the Guarantor.

Section 1304. Submission to Jurisdiction.

         The Guarantor agrees that any legal suit, action or proceeding arising
out of or based upon the Indenture or the Guarantees may be instituted in any
state or Federal court in the Borough of Manhattan, The City of New York, New
York, United States of America, waives, to the extent it may effectively do so,
any objection which it may have now or hereafter to the laying of the venue of
any such suit, action or proceeding, and irrevocably submits to the jurisdiction
of any such court in any such suit, action or proceeding. The Guarantor has
designated and appointed BP America Inc. (or any successor corporation) as the
Guarantor's authorized agent to accept and acknowledge on its behalf service of
any and all process which may be served in any such suit, action or proceeding
in any such court and agrees that service of process upon said agent at its

                                       74

office at 667 Madison Avenue, 22nd Floor, New York, New York 10021, attention of
the General Counsel (or at such other address in the Borough of Manhattan, The
City of New York, as the Guarantor may designate by written notice to the
Company and the Trustee), and written notice of said service to the Guarantor,
mailed or delivered to it, at Britannic House, 1 Finsbury Circus, London EC2M
7BA, England, attention of the Secretary (until another address is filed by the
Guarantor with the Trustee), shall be deemed in every respect effective service
of process upon the Guarantor in any such suit, action or proceeding and shall
be taken and held to be valid personal service upon the Guarantor, whether or
not the Guarantor shall then be doing, or at any time shall have done, business
within the State of New York, and any such service of process shall be of the
same force and validity as if service were made upon it according to the laws
governing the validity and requirements of such service in such State, and
waives all claim of error by reason of any such service. Said designation and
appointment shall be irrevocable until the Indenture shall have been satisfied
and discharged in accordance with Article Four. The Guarantor agrees to take all
action as may be necessary to continue the designation and appointment of BP
America Inc. or any successor corporation in full force and effect so that the
Guarantor shall at all times have an agent for service of process for the above
purposes in the Borough of Manhattan, The City of New York, New York, United
States of America.

                                *     *     *

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.
