<PAGE>

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing, 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. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section 104.

                  Without limiting the generality of the foregoing, unless
otherwise established in or pursuant to a Board Resolution or set forth or
determined in an Officers' Certificate, or established in one or more indentures
supplemental hereto, a Holder, including a Book-Entry Depositary that is a
Holder of a Global Security, may make, give or take, by a proxy, or proxies,
duly appointed in writing, any request, demand, authorization, direction,
notice, consent, waiver other action provided in this Indenture to be made,
given or taken by Holders, and a Book-Entry Depositary that is a Holder of a
Global Security may provide its proxy or proxies to the beneficial owners of
interests in any such Global Security through such Book-Entry Depositary's
standing instructions and customary practices.

                  (b) The fact and date of the execution by any Person of any
such instrument, writing or proxy may be proved by the affidavit of a witness of
such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the
individual signing such instrument, writing or proxy 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, writing or proxy, 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 Registered Securities shall be proved by
the Security Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

                  (e) The principal or face amount and serial numbers of Bearer
Securities of any series held by any Person, and the date of holding the same,

                                       11
<PAGE>

may be proved by the production of such Bearer Securities or by a certificate
executed by the Book-Entry Depositary for such Bearer Securities.

                  (f) If the Company shall solicit from the Holders of
Securities of any series any request, demand, authorization, direction, notice,
consent, waiver or other Act, the Company may, at its option, by Board
Resolution, fix in advance a record date for purposes of determining identity of
Holders of Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Company shall have no
obligation to do so. Any such record date shall be fixed at the Company's
discretion. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be sought or given before or
after the record date, but only the Holders of Securities of record at the close
of business on such record date shall be deemed to be Holders of Securities for
the purpose of determining whether Holders of the requisite proportion of
Securities of such series outstanding have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Securities of such series outstanding shall be
computed as of such record date.

                  With regard to any record date set pursuant to this
subsection, the Holders of outstanding Securities of the relevant series on such
record date (or their duly appointed agents), and only such Persons, shall be
entitled to take relevant action, whether or not such Holders remain Holders
after such record date. With regard to any action that may be taken hereunder
only by Holders of a requisite principal amount of Outstanding Securities of any
series (or their duly appointed agents) and for which a record date is set
pursuant to this subsection, the Company may, at its option, set an expiration
date after which no such action purported to be taken by any Holder shall be
effective hereunder unless taken on or prior to such expiration date by Holders
of the requisite principal amount of Outstanding Securities of such series on
such record date (or their duly appointed agents).

                  On or prior to any expiration date set pursuant to this
subsection, the Company may, on one or more occasions at its option, extend such
expiration date to any later date. Nothing in this subsection shall prevent any
Holder (or any duly appointed agent thereof) from taking, at any time, any
action contrary to or different from, any action previously taken, or purported
to have been taken, hereunder by such Holder, in which event the Company may set
a record date in respect thereof pursuant to this subsection. Notwithstanding
the foregoing or the Trust Indenture Act, the Company shall not set a record
date for, and the provisions of this paragraph shall not apply with respect to,
any action to be taken by Holders pursuant to Section 501, 502 or 512.

                  Upon receipt by the Trustee of written notice of any default
described in Section 501, any declaration of acceleration, or any rescission and
annulment of any such declaration, pursuant to Section 502 or any direction in
accordance with Section 512, a record date shall automatically and without any
other action by any Person be set for the purpose of determining the Holders of
Outstanding Securities of the series entitled to join in such notice,
declaration, rescission and annulment, or direction, as the case may be, which
record date shall be the close of business on the day the Trustee receives such
notice, declaration, rescission and annulment or direction, as the case may be.

                                       12

<PAGE>

The Holders of Outstanding Securities of such series on such record date (or
their duly appointed agent), and only such Persons, shall be entitled to join in
such notice, declaration, rescission and annulment, or direction, as the case
may be, whether or not such Holders remain Holders after such record date;
provided that, unless such notice, declaration, rescission and annulment, or
direction, as the case may be, shall have become effective by virtue of Holders
of the requisite principal amount of Outstanding Securities of such series on
such record date (or their duly appointed agents) having joined therein on or
prior to the 90th day after such record date, such notice of default,
declaration, rescission and annulment, or direction, as the case may be, given
or made by the Holders, as the case may be, shall automatically and without any
action by any Person be canceled and of no further effect. Nothing in this
paragraph shall prevent a Holder (or a duly appointed agent thereof) from
giving, before or after the expiration of such 90-day period, a notice of
default, a declaration of acceleration, a rescission and annulment of a
declaration of acceleration or a direction in accordance with Section 512,
contrary to or different from, or, after the expiration of such period,
identical to, a previously given notice, declaration, rescission and annulment,
or direction, as the case may be, that has been canceled pursuant to the proviso
to the preceding sentence, in which event a new record date in respect thereof
shall be set pursuant to this paragraph.

SECTION 105.      Notices, Etc. to Trustee and Company

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

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

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its
         registered office, with a copy addressed to the Guarantor at the
         address of its registered office, each as specified in the first
         paragraph of this instrument or at any other address previously
         furnished in writing to the Trustee by the Company.

SECTION 106.      Notice to Holders: Waiver

                  Where this Indenture provides for notice 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, (i) in the case of a Holder of Registered
Securities, at his address as it appears in the Security Register, and (ii) in
the case of a Holder of Global Bearer Securities, at the address provided in or
pursuant to the relevant Deposit Agreement of the relevant Book-Entry
Depositary, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to
Holders 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.

                                       13

<PAGE>

                  If Securities of any series are listed on the Luxembourg Stock
Exchange and the rules of such Stock Exchange so require, notice to Holders of
such Securities shall be published in a leading newspaper having general
circulation in Luxembourg.

                  If, 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 at the direction of the Company in
a manner reasonably calculated, to the extent practicable under the
circumstances, to provide prompt notice shall constitute a sufficient
notification for every purpose hereunder.

                  Except as otherwise expressly provided herein or otherwise
specified with respect to any Securities pursuant to Section 301, where this
Indenture provides for notice to Holders of Bearer Securities of any event and
the rules of any securities exchange on which such Bearer securities are listed
so require, such notice shall be sufficiently given to Holders of such Bearer
Securities if published in such newspaper or newspapers as may be specified in
such Securities on a Business Day at least twice, the first such publication to
be not earlier than the earliest date, and not later than the latest date,
prescribed for the giving of such notice. Any such notice by publication shall
be deemed to have been given on the date of the first such publication. In
addition, notice to the Holder of any Global Bearer Security shall be given by
mail in the manner provided above.

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

certified by the Secretary or an Assistant Secretary or other authorized officer
or Director, and delivered to the Trustee at or prior to the delivery of the

<PAGE>

of any series shall be executed by such additional Director or officer, if any,
as shall be specified pursuant to Section 301. The signature of any of these
officers on the Securities may be manual or facsimile.

                  Securities bearing the manual or facsimile signature of any
individual who was at any time the proper Director or officer of the Company
shall bind the Company, notwithstanding that such individual has ceased to hold
such office prior to the authentication and delivery of such Securities or did
not hold such office at the date of authentication 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 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. If the form or terms of the Securities of the series have been
established in 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 Section 601) shall be
fully protected in relying on, an Opinion of Counsel stating,

                  (a) if the form of such Securities has been established by or
         pursuant to a 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 established by
         or pursuant to Board Resolution as permitted by Section 301, that such
         terms have been established in conformity with the provisions of this
         Indenture; and

                  (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,
         reorganization and other laws of general applicability relating to or
         affecting the enforcement of creditors' rights and to general
         principles of equity.

                  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 time of authentication upon original
issuance of the first Security of such series to be issued.

                  Each Security shall be dated the date of its authentication.

                  No Security 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 or an Authenticating Agent by manual signature,

                                       21
<PAGE>

and such certificate upon any Security shall be conclusive evidence, and the
only evidence, that such Security has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 310 together
with a written statement (which need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, for all purposes of this Indenture such Security shall be deemed never
to have been authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

SECTION 304.      Transfer Agent and Paying Agent

                  For so long as Securities of a series are listed on the
Luxembourg Stock Exchange and such stock exchange shall so require, the Company
shall maintain a Paying Agent and Transfer Agent in Luxembourg.

                  The Company shall enter into an appropriate appointment letter
with any Registrar, Transfer Agent or Paying Agent not a party to this
Indenture, which shall implement the provisions of this Indenture that relate to
such Person. The Company shall notify the Trustee of the name and address of any
such Person. If the Company fails to maintain a Registrar or Paying Agent, the
Trustee shall act as such and shall be entitled to appropriate compensation
therefor pursuant to Section 607. The Company initially appoints the Trustee as
Registrar, Transfer Agent and Principal Paying Agent in The City of New York.

SECTION 305.      Temporary Securities

                  Pending the preparation of a permanent Global Security or
definitive Securities of any series, the Company may execute, and upon Company
Order the Trustee or the Authenticating Agent shall authenticate, and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued, in
registered form or, if authorized, in bearer form, and with such appropriate
insertions, omissions, substitutions and other variations as the officer or
officers executing such Securities may determine, as evidenced by their
execution of such Securities.

                  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 except as provided in Section 306 in
connection with a transfer and except that a Person receiving definitive Bearer
Securities shall bear the cost of insurance, postage, transportation and the
like. Upon surrender for cancellation of any one or more temporary Securities of
any series the Company shall execute and the Trustee or the Authenticating Agent
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series and of like tenor of authorized
denominations.

                                       22
<PAGE>

                  Upon any exchange of a portion of a temporary Global Security
for a definitive Global Security for the individual Securities represented
thereby pursuant to this Section 305 or Section 306, the temporary Global
Security shall be endorsed by the Trustee to reflect the reduction of the
principal amount of such temporary Global Security, and such principal amount
shall be reduced for all purposes by the amount so exchanged and endorsed.

SECTION 306.      Registration, Registration of Transfer and Exchange

                  The Company shall cause to be kept at the Corporate Trust
Office a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Trustee is hereby appointed "Security Registrar" for the purpose of
registering Registered Securities and transfers of Registered Securities as
herein provided. The Company may have one or more coregistrars and the term
"Security Registrar" includes any co-registrar.

                  Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency in a Place of Payment for that
series, the Company shall execute, and the Trustee or the Authenticating Agent
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Registered Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor.

                  At the option of the Holder, any Registered Security or
Registered Securities of any series, other than a Global Security, may be
exchanged for other Registered Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Registered Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
upon receipt of a Company Order the Trustee or the Authenticating Agent shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive. Bearer Securities may not be delivered by the
Trustee, the Authenticating Agent or the Security Registrar in exchange for
Registered Securities.

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

                  Every Registered 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.

                  Interests in a Global Security or Securities may be exchanged
for definitive Registered Securities of the same series in whole or in part only
under the circumstances provided in this Indenture, in an Officers' Certificate
(pursuant to a Board Resolution) or in an indenture supplemental hereto pursuant

                                       23

to which Securities of that series are issued or in the Securities of that
series. In such event the Company will execute, and the Trustee or the
authenticating Agent, upon receipt of a Company Order for the authentication and
delivery of definitive Registered Securities of such series, will authenticate
and deliver such definitive Registered Securities. Any such definitive
Registered Securities so issued shall be registered in thee name of such Person
or Persons as the Book-Entry Depositary shall instruct the Trustee and the
Security Registrar in writing. The Trustee or the Security Registrar shall
deliver such definitive Registered Securities to the Persons in whose names such
definitive Registered Securities are so registered. Upon the exchange (i) in
whole of a Global Security or Securities for definitive Registered Securities in
equal aggregate principal amount, such Global Security or Securities shall be
delivered to the Trustee for cancellation or (ii) in part of a Global Security
or Securities for definitive Registered Securities, then the principal amount of
such Global Security or Securities shall be reduced by an endorsement on such
Global Security or Securities in an amount equal to the aggregate principal
amount of such definitive Registered Securities. Interests in a Global Security
or Securities may not be exchanged for definitive Bearer Securities.
Notwithstanding the foregoing, interests in a Global Security may not be
exchanged for definitive Registered Securities during the sixteen day period
immediately prior to and including each Interest Payment Date.

                  No service charge shall be made to the Holder 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 Sections 305, 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 under Section 1103 and ending at the close of business on the day of
such mailing, (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 or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for
a Registered Security of the series (but only if and under the circumstances for
which the Securities of such series are issuable as Registered Securities),
provided that such Registered Security shall be immediately surrendered for
redemption with written instructions for payment consistent with the provisions
of this Indenture.

                  The provisions of this Section 306 are, with respect to any
Global Security, subject to Section 312 hereof.

SECTION 307.      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 and bearing a number not contemporaneously outstanding.

                                       24

<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 written 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 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 the issuance of any new Security under this Section 307,
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 307 in lieu of any destroyed, lost or stolen Security shall constitute
an original additional contractual obligation of the Company, 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 307 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 308.      Payment of Interest: Interest Rights Reserved

                  Interest on any Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid (in the
case of a Bearer Security) to the bearer thereof and (in the case of a
Registered Security) to the Person in whose name that Registered Security (or
one or more Predecessor Securities) is registered at the close of business on
the Regular Record Date for such interest.

                  Payment of interest, if any, in respect of any Registered
Security will be made by check mailed to the address of the Person entitled
thereto as such person's address appearing in the Security Register. Payment of
interest, if any, in respect of any Registered Security may also be made, in the
case of a Holder of at least U.S. $1,000,000 (or the equivalent thereof in other
currencies) aggregate principal amount of Registered Securities, and payment of
interest, if any, in respect of a Global Registered Security shall be made, by
wire transfer to an account denominated in the same currency as the relevant
Securities maintained by the Holder with a bank in the country in whose currency
the relevant Securities are denominated; provided that such Holder elects
payment by wire transfer by giving written notice to the Trustee or a Paying
Agent to such effect designating such account no later than 15 days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion.

                                       25
<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, in the case of Registered
Securities, forthwith cease to be payable to the Holder thereof on the relevant
Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Registered Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on a Special Record Date for the payment of
         such Defaulted Interest, which shall be fixed in the following manner.
         The Company shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Registered Security of
         such series and the date of the proposed payment, 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 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. Unless the Trustee is acting as the Security
         Registrar, promptly after such Special Record Date, the Company shall
         furnish the Trustee with a list, or shall make arrangements
         satisfactory to the Trustee with respect thereto, of the names and
         addresses of, and respective principal amounts of such Registered
         Securities held by, the Holders appearing on the Security Register at
         the close of business on such Special Record Date. 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 Registered Securities of any series or any Global Registered
         Security in any other lawful manner not inconsistent with the
         requirements of any securities exchange on which such Registered
         Securities may be listed, and upon such notice as may be required by
         such exchange.

                  Defaulted Interest on Bearer Securities shall be payable to
         the bearer thereof at the time of payment of such Defaulted Interest by
         the Company.

                  Subject to the foregoing provisions of this Section 308, 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 309.      Persons Deemed Owners

                  Prior to due presentment of a Registered Security for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Registered Security for the purpose of receiving
payment of principal of; premium, if any, and (subject to Section 308) interest,
if any, on such Registered Security and for all other purposes whatsoever,
whether or not such Registered Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary. All such payments so made to any such person, or upon such
person's order, shall be valid, and, to the extent of the sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any
such Security.

                  The Company, the Trustee and any agent of the Company or the
Trustee may treat the Book-Entry Depositary for a Global Bearer Security as the
absolute owner of such Global Bearer Security for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Global Bearer Security or coupon shall be overdue, and
neither the Company or the Trustee nor any agent of the Company 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 Book-Entry Depositary shall have any rights under this
Indenture with respect to such Global Security, and such Book-Entry Depositary
may be treated by the Company, the Trustee, and any agent of the Company or the
Trustee as the owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall impair, as between a Book-
Entry Depositary and such holders of beneficial interests, the operation of
customary practices governing the exercise of the rights of the Book-Entry
Depositary as holder of any Security.

SECTION 310.      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 canceled by it. The Company may at any time
deliver to the Trustee for cancellation any Securities previously authenticated
and delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly canceled by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities canceled as provided in this Section 310, except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall
be disposed of as directed by a Company Order.

SECTION 311.      Computation of Interest

                                       27

<PAGE>

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

SECTION 312.      Global Securities

                  If the Company shall establish pursuant to Section 301 that
the Securities of a particular series are to be issued in the form of a Global
Security, then the Company shall execute and the Trustee shall, in accordance
with Section 303, authenticate and deliver, a Global Security or Securities
which (i) shall represent, and shall be denominated in an aggregate amount equal
to the aggregate principal amount of; all of the Outstanding Securities of such
series, (ii) shall be in bearer form or, if in registered form, registered in
the name of the Book-Entry Depositary or its nominee, (iii) shall be delivered
by the Trustee to the Book-Entry Depositary or pursuant to the Book-Entry
Depositary's instruction and (iv) shall bear a legend substantially to the
following effect:

                  "This Security is a Global Security within the meaning of the
Indenture hereinafter referred to and if this Security is in bearer form, is
held by a Book-Entry Depositary or, if this Security is in registered form, is
registered in the name of a Book-Entry Depositary or a nominee of a Book-Entry
Depositary. This Security is exchangeable for Securities, if this Security is in
bearer form, held by, or if this Security is in registered form, registered in
the name of, a person other than the Book-Entry Depositary or its nominee only
in the limited circumstances described in the Indenture.

                  "Unless this Global Security is presented by an authorized
representative of the Book-Entry Depositary to the Company or its agent for
registration of transfer, if this Security is in registered form, exchange or
payment, and any definitive Registered Security is issued in the name or names
as directed in writing by the Book-Entry Depositary, ANY TRANSFER, PLEDGE OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL in as
much as the bearer or the registered owner hereof; as the case may be, the
Book-Entry Depositary, has an interest herein."

                  Unless and until definitive Registered Securities of a series
are issued in exchange for the Global Security of a series as permitted by this
Indenture, the Global Security of a series may be transferred, in whole but not
in part and in the manner provided in Section 306, only to another nominee of
the Book-Entry Depositary for such series, or to a successor Book-Entry
Depositary for such series selected or approved by the Company or to a nominee
of such successor Book-Entry Depositary.

                  No Security that is not a Global Bearer Security may be
payable to bearer (except as otherwise provided in an indenture supplemental
hereto or in an Officers' Certificate (pursuant to a Board Resolution) pursuant
to Section 301(16)).

payments of any principal, premium or interest in respect thereof and any right
to receive any Additional Amount as provided in Section 1009), and the Trustee

         delivered (other than (i) Securities which have been destroyed, lost or
         stolen and which have been replaced or paid as provided in Section 307

         or discharged from such trust, as provided in Section 1003) 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

and the Company, 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 of (a) money in the currency or units of currency in which such
Securities are payable, or (b) U.S. Government Obligations or U.K. Government

currency in which such Securities are payable), which through the payment of
interest and principal in respect thereof in accordance with their terms will
provide not later than one day before the Stated Maturity or Redemption Date, as
the case may be, money in an amount, or (c) a combination of money or U.S.
Government Obligations or U.K. Government Obligations, as applicable, as
provided in (b) above, in each case, 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, if any, to the
date of such deposit (in the case of Securities which have become due and
payable) or to the Stated Maturity or Redemption Date, as the case may be;

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

         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 to the Trustee under Section 607, the
obligations of the Trustee 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 401 or if money or U.S. Government Obligations shall
have been deposited with or received by the Trustee pursuant to Section 403, the
obligations of the Trustee under Section 402 and the last paragraph of Section
1003 shall survive.

SECTION 402.      Application of Trust Money

                  (a) Subject to the provisions of the last paragraph of Section
1003, all money or U.S. Government Obligations or U.K. Government Obligations
deposited with the Trustee pursuant to Sections 401 or 403, and all money
received by the Trustee in respect of U.S. government Obligations or U.K.
Government Obligations deposited with the Trustee pursuant to Sections 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, to the persons entitled
thereto, of the principal of, premium, if any, and interest, if any, on the
Securities for whose payment such money has been deposited with or received by
the Trustee or to make mandatory sinking fund payments or analogous payments as
provided by Sections 401 or 403.

accountants expressed in a written certification thereof delivered to the
Trustee, are then in excess of the amount thereof which then would have been
required to be deposited for the purpose for which such U.S. Government
Obligations or U.K. Government Obligations or money was deposited or received.
This provision shall not authorize the sale by the Trustee of any U.S.

SECTION 403.      Satisfaction, Discharge and Defeasance of Securities of any
Series

                  The Company, at its option, may elect (a) to be discharged
from any and all obligations in respect of the Securities of a series (except in
each case for the obligations to register the transfer or exchange of the
Securities of that series, replace stolen, lost or mutilated Securities of that
series, maintain paying agencies and hold moneys for payment in trust); or (b)
not to comply with any term, provision or condition set forth in Sections 801,
1004 and 1005 with respect to the Securities of any series, provided that the
following conditions shall have been satisfied:

                  The Company has irrevocably deposited or caused to be
deposited (except as provided in Section 607, 402(d) and the last paragraph of
Section 1003) with the Trustee (specifying that each deposit is pursuant to this
Section 403) 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 or (ii) U.S. Government Obligations or U.K. Government
Obligations, as applicable, which through the payment of interest and principal
in respect thereof in accordance with their terms will provide money, or (iii) a
combination thereof, in each case, in an amount sufficient, in the opinion of a
nationally recognized firm of independent accountants, to pay and discharge the
principal of, premium, if any, and interest, if any (including any Additional
Amounts then known), if any, on the outstanding Securities of such series on the
dates such payments are due in accordance with the terms of the Securities of
such series, (or if the Company has designated a redemption date pursuant to the
final sentence of this paragraph, to and including the redemption date so
designated by the Company), and no Event of Default or event which with notice
or lapse of time would become an Event of Default (including by reason of such
deposit) with respect to the Securities of such series shall have occurred and
be continuing on the date of such deposit or, insofar as Section 501(7) is
concerned, at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be satisfied
until the expiration of such period), and the Securities of such series will not
be delisted by any securities exchange on which they are traded as a result of
the deposit of trust funds in trust. To exercise any such option, the Company is
required to deliver to the Trustee: (i) an opinion of independent counsel of
recognized standing to the effect that (x) the Holders of the Securities of such
series will not recognize income, gain or loss for United States federal income
tax purposes as a result of such deposit, and will be subject to United States
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case absent such deposit, which in the case of clause (a)
must be based on a change in law or a published ruling by the United States
Internal Revenue Service and (y) the deposit shall not result in the Company
being deemed to be an "investment company" required to be registered under the
Investment Company Act of 1940, as amended; (ii) an opinion of independent
counsel in the Eligible Jurisdiction of recognized standing, if applicable, to
the effect that (x) the Holders will not recognize income, gain or loss for tax
purposes of such Eligible Jurisdiction as a result of such deposit and will be
subject to income tax in such Eligible Jurisdiction on the same amounts, in the
same manner and at the same times as would have been the case absent such

SECTION 501.      Events of Default

                  "Event of Default", wherever used herein with respect to
Securities of any series, means any one of the following events:

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

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

                  (3) default in the payment of any installment of any sinking
         fund provided with respect to such series, when and as due by the terms
         of a Security of that series; or

                  (4) material default in the performance, or material breach,
         of any covenant or obligation of the Company or the Guarantor in this
         Indenture (other than a covenant a default in whose performance or
         whose breach is elsewhere in this Section 501 specifically dealt with
         or which has expressly been included in this Indenture solely for the
         benefit of a series of Securities other than that series) and
         continuance of such material default or breach for a period of 90 days
         after there has been given, by registered or certified mail, to the
         Company or the Guarantor by the Trustee or to the Company or the
         Guarantor and the Trustee by the Holders of at least 25% in aggregate
         principal amount of the Outstanding Securities of that series a written
         notice specifying such default or breach and requiring it to be
         remedied and stating that such notice is a "Notice of Default"
         hereunder; or

                  (5) a default in the payment of the principal of any bond,
         debenture, note or other evidence of indebtedness, in each case for
         money borrowed, or in the payment of principal under any mortgage,

                                       32
<PAGE>

         indenture (including this Indenture) or instrument under which there
         may be issued or by which there may be secured or evidenced any
         indebtedness for money borrowed, of the Company, the Guarantor or any
         Significant Subsidiary, which default for payment of principal is in an
         aggregate principal amount exceeding U. S. $50,000,000 (or its
         equivalent in any other currency or currencies) when such indebtedness
         becomes due and payable (whether at maturity, upon redemption or
         acceleration or otherwise), if such default shall continue unremedied
         or unwaived for more than 30 Business Days and the time for payment of
         such amount has not been expressly extended; provided, however, that,
         subject to the provisions of Sections 601 and 602, the Trustee shall
         not be deemed to have knowledge of such default unless either (A) a
         Responsible Officer of the Trustee shall have actual knowledge of such
         default or (B) the Trustee shall have received written notice thereof
         from the Company or the Guarantor, from any Holder, from the holder of
         any such indebtedness or from the trustee under any such mortgage,
         indenture or other instrument; and provided, further, that if such
         default under such indenture or instrument shall be remedied or cured
         by the Company, the Guarantor or such Significant Subsidiary or waived
         by the holders of such indebtedness, then the Event of Default
         hereunder by reason thereof shall be deemed likewise to have been
         remedied, cured or waived without further action upon the part of the
         Trustee or any of the Holders; or

                  (6) any Guarantee shall be held in a judicial proceeding to be
         unenforceable or invalid or shall cease for any reason to be in full
         force and effect; or

                  (7) the failure of the Company, the Guarantor, or a
         Significant Subsidiary generally to pay its debts as they become due,
         or the admission in writing of its inability to pay its debts
         generally, or the making of a general assignment for the benefit of its
         creditors, or the institution of any proceeding by or against the
         Company, the Guarantor or a Significant Subsidiary (other than any such
         proceeding brought against the Company, the Guarantor or a Significant
         Subsidiary that is dismissed within 180 days from the commencement
         thereof) seeking to adjudicate it bankrupt or insolvent, or seeking
         liquidation, winding up, reorganization, arrangement, adjustment,
         protection, relief or composition of it or its debts under any law
         relating to bankruptcy, insolvency, reorganization, moratorium or
         relief of debtors, or seeking the entry of an order for relief or
         appointment of an administrator, receiver, trustee, intervenor or other
         similar official for it or for any substantial part of its property, or
         the taking of any action by the Company, the Guarantor or a Significant
         Subsidiary to authorize any of the actions set forth in this
         subparagraph (7); or

                  (8) any other Event of Default provided in the supplemental
         indenture or provided in or pursuant to the Board Resolution under
         which such series of Securities is issued or in the form of Security
         for such series.

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, the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion

                                       33
<PAGE>

of the principal amount of such Securities as may be specified in the terms
thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.

                  At any time after such declaration of acceleration with
respect to Securities of any series has been made, but before a judgment or
decree for payment of money has been obtained by the Trustee as hereinafter in
this Article provided, if all Events of Default with respect to Securities of
that series have been cured or waived (other than the non-payment of principal
of the Securities which has become due solely by reason of such declaration of
acceleration) then such declaration of acceleration and its consequences shall
be automatically annulled and rescinded.

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

                  For all purposes under this Indenture, if a portion of the
principal of any Original Issue Discount Securities shall have been accelerated
and declared due and payable pursuant to the provisions hereof, then, from and
after such declaration, unless such declaration has been rescinded and annulled,
the principal amount of such Original Issue Discount Securities shall be deemed,
for all purposes hereunder, to be such portion of the principal thereof as shall
be due and payable as a result of such acceleration, and payment of such portion
of the principal thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all other amounts
owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

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 of a series 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,
         premium, if any, on any Security of a series at the Stated Maturity
         thereof,

the Company will, upon written demand of the Trustee, pay to it, for the benefit
of the Holders of such Securities of such series, the whole amount then due and
payable on such Securities of such series for principal of, premium, if any, and
interest, if any, and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal of, premium, if any, and
interest, at the rate or rates prescribed therefor in such Securities of such
series, 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

                                       34
<PAGE>

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 or any other obligor upon such Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such
Securities, wherever situated.

                  If any 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.

SECTION 504.      Trustee May File Proofs of Claim

                  In case of the pendency of any receivership, insolvency,
liquidation (other than a solvent liquidation), bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor on the Securities or the property of the
Company or of such other obligor or the creditors of either or both of them, 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
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceeding or otherwise,

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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder 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 authorizes or consent to, 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

                                       35

<PAGE>

                  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 any 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 with respect to the Securities of any
series, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal of, premium, if any, or
interest, if any, 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 to the Trustee under
Section 607;

                  SECOND: In case the principal and premium, if any, of the
Securities of such series in respect of which moneys have been collected shall
not have become and be then due and payable, to the payment of interest, if any,
on the Securities of such a series in default in the order of the maturity of
the installments of such interest, with interest (to the extent that such
interest has been collected by the Trustee and to the extent permitted by law)
upon the overdue installments of interest at the rate prescribed there for in
such Securities, such payments to be made ratably to the Persons entitled
thereto, without discrimination or preference;

                  THIRD: In case the principal or premium, if any, of the
Securities of such series in respect of which moneys have been collected shall

amount then owing and unpaid on all the Securities of such series for principal,
premium, if any, and interest, if any, with interest upon the overdue principal
of premium, if any, and (to the extent that such interest has been collected by
the Trustee and to the extent permitted by law) upon overdue installments of
interest at the rate prescribed therefor in the Securities of such series; and
in case such moneys shall be insufficient to pay in full the whole amount so due
and unpaid upon the Securities of such series, then to the payment of such
principal and any premium and interest, without preference or priority of
principal over interest, or of interest over principal or premium, or of any
installment of interest over any other installment of interest, or of any
Security of such series over any other Security of such series, ratably to the
aggregate of such principal and any premium and accrued and unpaid interest; and

                  FOURTH: To the payment of the remainder, if any, to the
Company or any other Person lawfully entitled thereto.

SECTION 507.      Limitation on Suits

                                       36

<PAGE>

                  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
         indemnity satisfactory to the Trustee against the costs, expenses and
         liabilities to be incurred in compliance with such request;

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

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

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

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

                  Notwithstanding Section 507, the Holder of any Security shall
have the right, which is absolute and unconditional, to receive payment of the
principal of, premium, if any, or (subject to Section 307) interest, if any, 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, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Company, the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

SECTION 510.      Rights and Remedies Cumulative

                                       37

<PAGE>

                  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

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

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

                  (3) the Trustee shall not determine that the action so
         directed would be prejudicial to Holders not taking part in such
         action.

SECTION 513.      Waiver of Past Defaults

                  The Holders of not less than a majority in aggregate 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 of, premium, if any,
         or interest, if any, on any Security of such series, or

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

                                       38

<PAGE>

                  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 or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant in such
suit, but the provisions of this Section 514 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of, premium, if any,
interest, if any, on any Security on or after the Stated Maturity or Maturities
expressed in such Security.

                                   ARTICLE SIX

                                   THE TRUSTEE

SECTION 601.      Certain Duties and Responsibilities

                  (a) Except during the continuance of a default with respect to
the Securities of any series,

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

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

                  (b) In case a default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

                                       39

<PAGE>

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

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

                  (2) no provision of this Indenture shall require the Trustee
         to spend 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 repayment of such funds or
         adequate indemnity against such risk or liability satisfactory to the
         Trustee has not been assured to it; and

                  (3) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction of the Holders of not less than a majority in principal
         amount of the outstanding Securities of any series, determined as
         provided in Section 512, relating to the time, method and place of
         conducting any proceeding for any remedy available to the Trustee, or
         exercising any trust or power conferred upon the Trustee, under this
         Indenture with respect to the Securities of such series.

                  (d) Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 601.

SECTION 602.      Notice of Defaults

                  (a) Within 90 days after the occurrence 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 notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in the
payment of the principal of, premium, if any, or interest, if any, 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 a Responsible Officer of the
Trustee in good faith determines 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 602, the term "default" means, with respect to Securities of any
Series, 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.

                  (b) If any installment of principal of or premium, if any,
interest on the Securities of a series, for which, pursuant to Section 301,
provision has been made for the Guarantee thereof by the Guarantor, is not paid

                                       40
<PAGE>

when due in accordance with Section 1001, then no later than 11:00 a.m. (New
York City time in the case of payments in US Dollars and London time in the case
of payments in Pounds Sterling) on the due date for such payment, the Trustee
shall notify the Guarantor of such nonpayment.

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

         agents and counsel, which compensation, expenses and disbursements
         shall be set forth in sufficient written detail to the satisfaction of

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 either
eliminate such 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.

SECTION 609.      Corporate Trustee Required: Eligibility

                  There shall at all times be a Trustee hereunder which shall be
eligible to act as trustee under the Trust Indenture Act and which shall have a
combined capital and surplus of at least U.S.$50,000,000. If the Trustee does
not have an office in The City of New York, the Trustee may appoint an agent in
The City of New York reasonably acceptable to the Company to conduct any
activities which the Trustee may be required under this Indenture to conduct in
The City of New York. If the Trustee does not have an office in The City of New
York or has not appointed an agent in The City of New York, the Trustee shall be
a participant in The Depository Trust Company and FAST distribution systems. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of a United States federal, state, territorial or
District of Columbia supervising or examining authority, then for the purposes
of this Section 609, the combined capital and surplus of such corporation shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 609, the Trustee
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

SECTION 610.      Resignation and Removal: Appointment of Successor Trustee

                  (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 acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 10 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) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company.

                  (d) If at any time:

                  (1) the Trustee shall fail to comply with Section 310(b) of
         the Trust Indenture Act pursuant to Section 608 with respect to any

                                       43
<PAGE>

         series of Securities after written request therefor by the Company 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 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, 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 no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company 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 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 or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument

                                       44
<PAGE>

transferring to such successor Trustee all the rights, powers and trusts of
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 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
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such
successor Trustee relates; but on request of the Company or any successor
trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

                  (c) Upon request of any such successor Trustee, the Company
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all such rights, powers and trusts
referred to in paragraph (a) or (b) of this Section 611, as the case may be.

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

SECTION 612.      Merger, Conversion, Consolidation or Succession to Business

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder;
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor

<PAGE>

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 Collecting of Claims Against Company

                  (a) Subject to Subsection (b) of this Section 613, if the
Trustee shall be or shall become a creditor, directly or indirectly, secured or
unsecured, of the Company within three months prior to a default, as defined in
Subsection (c) of this Section 613, or subsequent to such a default, then,
unless and until such default shall be cured, the Trustee shall set apart and
hold in a special account for the benefit of the Trustee individually, the
Holders of the Securities and the holders of other indenture securities, as
defined in Subsection (c) of this Section 613:

                  (1) an amount equal to any and all reductions in the amount
         due and owing upon any claim as such creditor in respect of principal
         or interest effected after the beginning of such three months' period
         and valid as against the Company and its other creditors, except any
         such reduction resulting from the receipt or disposition of any
         property described in paragraph (2) of this Subsection, or from the
         exercise of any right of setoff which the Trustee could have exercised
         if a petition in bankruptcy had been filed by or against the Company
         upon the date of such default; and

                  (2) all property received by the Trustee in respect of any
         claims as such creditor, whether as security therefor, or in
         satisfaction or composition thereof, or otherwise, after the beginning
         of such three months' period, or an amount equal to the proceeds of any
         such property, if disposed of, subject, however, to the rights, if any,
         of the Company and its other creditors in such property or such
         proceeds.

                  Nothing herein contained, however, shall affect the right of
the Trustee:

                  (A) to retain for its own account (i) payments made on account
         of any such claim by any Person (other than the Company) who is liable
         thereon, and (ii) the proceeds of the bona fide sale of any such claim
         by the Trustee to a third Person, and (iii) distributions made in cash,
         securities or other property in respect of claims filed against the
         Company in bankruptcy or receivership or in proceedings for
         reorganization pursuant to the Federal Bankruptcy Act or applicable
         State law;

                  (B) to realize, for its own account, upon any property held by
         it as security for any such claim, if such property was so held prior
         to the beginning of such three months' period;

                  (C) to realize, for its own account, but only to extent of the
         claim hereinafter mentioned, upon any property held by it as security
         for any such claim, if such claim was created after the beginning of
         such three months' period and such property was received as security
         therefor simultaneously with the creation thereof, and if the Trustee
         shall sustain the burden of proving that at the time such property was
         so received the Trustee had no reasonable cause to believe that a
         default, as defined in Subsection (c) of this Section 613, would occur
         within three months; or

                                       46

<PAGE>

                  (D) to receive payment on any claim referred to in paragraph
         (B) or (C), against the release of any property held as security for
         such claim as provided in paragraph (B) or (C), as the case may be, to
         the extent of the fair value of such property.

                  For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such three months' period for property held
as security at the time of such substitution shall, to the extent of the fair
value of the property released, have the same status as the property released,
and, to the extent that any claim referred to in any of such paragraphs is
created in renewal of or in substitution for or for the purpose of repaying or
refunding any pre-existing claim of the Trustee as such creditor, such claim
shall have the same status as such pre-existing claim.

                  If the Trustee shall be required to account for the funds and
property held in such special account, the proceeds thereof shall be apportioned
among the Trustee, the Holders and the holders of other indenture securities in
such manner that the Trustee, the Holders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law or winding up or administration pursuant
to the insolvency laws of the Cayman Islands or the United Kingdom, as
applicable, the same percentage of their respective claims, figured before
crediting to the claim of the Trustee anything on account of the receipt by it
from the Company of the funds and property in such special account and before
crediting to the respective claims of the Trustee and the Holders and the
holders of other indenture securities dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Act or applicable State law or winding up or
administration pursuant to the insolvency laws of the Cayman Islands or the
United Kingdom, as applicable, but after crediting thereon receipts on account
of the indebtedness represented by their respective claims from all sources
other than from such dividends and from the funds and property so held in such
special account. As used in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such claim, in
bankruptcy or receivership or proceedings for reorganization pursuant to the
Federal Bankruptcy Act or applicable State law or winding up or administration
pursuant to the insolvency laws of the Cayman Islands or the United Kingdom, as
applicable, whether such distribution is made in cash, securities or other
property, but shall not include any such distribution with respect to the
secured portion, if any, of such claim.

                  Any Trustee which has resigned or been removed after the
beginning of such three months' period shall be subject to the provisions of
this Subsection as though such resignation or removal had not occurred. If any
Trustee has resigned or been removed prior to the beginning of such three
months' period, it shall be subject to the provisions of this Subsection if and
only if the following conditions exist:

                  (i) the receipt of property or reduction of claim, which would
         have given rise to the obligation to account, if such Trustee had
         continued as Trustee, occurred after the beginning of such three
         months' period; and

                                       47

<PAGE>

                  (ii) such receipt of property or reduction of claim occurred
         within three months after such resignation or removal.

                  (b)  There shall be excluded from the operation of Subsection
(a) of this Section 613 a creditor relationship arising from:

                  (1) the ownership or acquisition of securities issued under
         any indenture, or any security or securities having a maturity of one
         year or more at the time of acquisition by the Trustee;

                  (2) advances authorized by a receivership or bankruptcy court
         of competent jurisdiction or by this Indenture, for the purpose of
         preserving any property which shall at any time be subject to the lien
         of this Indenture or of discharging tax liens or other prior liens or
         encumbrances thereon, if notice of such advances and of the
         circumstances surrounding the making thereof is given to the Holders at
         the time and in the manner provided in this Indenture;

                  (3) disbursements made in the ordinary course of business in
         the capacity of trustee under an indenture, transfer agent, registrar,
         custodian, paying agent, fiscal agent or depository, or other similar

SECTION 614.      Authenticating Agents

                  From time to time the Trustee, with the prior written approval
of the Company, may appoint one or more Authenticating Agents with respect to
one or more series of Securities with power to act on the Trustee's behalf and
subject to its direction in the authentication and delivery of Securities of
such series or in connection with transfers and exchanges under Sections 304,
305, 306, and 1104 as fully to all intents and purposes as though the
Authenticating Agent had been expressly authorized by those Sections of this
Indenture to authenticate and deliver Securities of such series. For all
purposes of this Indenture, the authentication and delivery of Securities by an
Authenticating Agent pursuant to this Section 614 shall be deemed to be
authentication and delivery of such Securities "by the Trustee". Each such
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, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least U.S. $50,000,000 and subject to supervision or examination by
Federal, State or District of Columbia authority. If such corporation publishes
reports of condition at least annually pursuant to law or the requirements of
such authority, then for the purposes of this Section 614 the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section 614, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section 614.

                  Any corporation into which any Authenticating Agent may be
merged or with which it may be consolidated, or any corporation resulting from,
any merger or consolidation or to which any Authenticating Agent shall be a
party, or any corporation succeeding to the corporate trust business of any
Authenticating Agent, shall be the successor of the Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this

                                       49
<PAGE>

Section 614, without the execution or filing of any paper or any further act on
the part of the parties hereto or the Authenticating Agent or such successor
corporation.

                  An Authenticating Agent may resign at any time by giving
written notice of resignation to the Trustee and to the Company. The Trustee may
at any time terminate the agency of any Authenticating Agent by giving written
notice of termination to such Authenticating Agent and to the Company. Upon
receiving such a notice of resignation or upon such a termination, or in case at
any time any Authenticating Agent shall cease to be eligible under this Section
614, the Trustee may appoint a successor Authenticating Agent with the prior
written approval of the Company and shall mail notice of such appointment to all
Holders of Securities of the series with respect to which such Authenticating
Agent will serve, as the names and addresses of such Holders appear on 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 614.

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section 614 as
may be agreed in a separate writing among the Company, the Trustee and such
Authenticating Agent, and the Trustee shall be entitled to be reimbursed for
such payments pursuant to Section 607.

                  If an appointment with respect to one or more series of
Securities is made pursuant to this Section 614, the Securities of such series
may have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternate certificate of authentication in the following
form:

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

Dated:                                       _________________________________

                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 701.      Company to Furnish Trustee Names and Addresses of Holders

                  The Company will furnish or cause to be furnished to the
Trustee with respect to the Registered Securities of each
series

                  (a) semi-annually, not later than 15 days after each Regular
Record Date, or, in the case of any series of Registered Securities on which
semiannual interest is not payable, not more than 15 days after such semi-annual
dates as may be specified by the Trustee, a list, in such form as the Trustee
may reasonably require, of the names and addresses of the Holders as of such
Regular Record Date or semi-annual date, as the case may be, and

                  (b) at such other times as the Trustee may request in writing,
within 30 days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 days prior to the time
such list is furnished;

provided, however, that if and so long as the Trustee is Security Registrar for
any series of Registered Securities, no such list shall be required to be
furnished with respect to any such series.

SECTION 702.       Preservation of Information: Communications to Holders

                  (a)      The Trustee shall preserve, in as current a form as
is reasonably practicable, the names and addresses of Holders contained in the
most recent list furnished to the Trustee as provided in Section 701 and the
names and addresses of Holders received by the Trustee in its capacity as
Security Registrar.

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

                  (i)      afford such applicants access to the information
                           preserved at the time by the Trustee in accordance
                           with Section 702(a), or

                  (ii)     inform such applicants as to the approximate number
                           of Holders whose names and addresses appears in the
                           information preserved at the time by the Trustee in
                           accordance with Section 702(a), and as to the
                           approximate cost of mailing to such Holders the form
                           of proxy or other communication, if any, specified in
                           such application.

                                       51

<PAGE>

                  If the Trustee shall elect not to afford such applicants
access to such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 702(a) a copy of
the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the beat interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to the applicants respecting their
application.

                  (c) Every Holder of Securities, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee nor any agent of either of them shall be held accountable, by reason of
the disclosure of any such information as to the names and addresses of the
Holders in accordance with Section 702(b), regardless of the source from which
such information was derived, and that the Trustee shall not be held accountable
by reason of mailing any material pursuant to a request made under Section
702(b).

SECTION 703.      Reports by Trustee

                  (a) Within 60 days after July 1 of each year, commencing July

         claim a lien or charge, prior to that of the Securities, on any
         property or funds held or collected by it as Trustee, except that the
         Trustee shall not be required (but may elect) to report such advances

                                       52

         on the Securities) to the Trustee in its individual capacity, on the
         date of such report, with a brief description of any property held as
         collateral security therefor, except an indebtedness based upon a

         of a default, notice of which, has been or is to be withheld by the
         Trustee in accordance with Section 602.

                  (b) The Trustee shall transmit by mail to all Holders of
Securities a brief report with respect to the character and amount of any
advances (and if the Trustee elects so to state. the circumstances surrounding
the making thereof) made by the Trustee (as such) since the date of the last
report transmitted pursuant to Subsection (a) of this Section 703 (or if no such
report has yet been so transmitted, since the date of execution of this

transmission to Holders, be filed by the Trustee with each United States
national securities exchange upon which any Securities are listed, with the

obligations the Company or the Guarantor shall be automatically released from
such obligations, provided that immediately after giving effect to such
transaction no Event of Default, and no event which, after notice or lapse of

jurisdiction located outside of a Taxing Jurisdiction and withholding or
deduction is required by law for or on account of any present or future taxes,

duties, assessments or governmental charges of whatever nature imposed, levied,
collected, withheld or assessed by or within such jurisdiction or by or within

power to tax, the successor entity shall pay to the relevant Holder of the
Securities of such series such Additional Amounts, under the same circumstances
and subject to the same limitations as are specified for in Section 1009 hereof,
but substituting for the applicable Taxing Jurisdiction in each place the name
of such jurisdiction. In addition, such successor entity shall be entitled to
effect an optional tax redemption under the same circumstances and subject to
the same limitations as are set forth in Section 1108 hereof, but substituting
for the applicable Taxing Jurisdiction in each place the name of the country
under the laws of which such successor entity is organized, managed and
controlled or has a place of business and substituting the date of such
succession for the date of original issuance of the Securities of such series.

merger by the Company or the Guarantor into any other corporation or any
conveyance, transfer, lease or other disposition of the properties and assets of
the Company or the Guarantor substantially as an entirety in accordance with
Section 801, the successor corporation formed by such consolidation or into

Indenture with the same effect as if such successor corporation had been named
as the Company or the Guarantor herein, and thereafter the predecessor
corporation shall be relieved of all obligations and covenants under this
Indenture and the Securities.

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

         supplemental indenture and Securities of any series subsequently
         created to which such change or elimination is made applicable by the
         subsequent supplemental indenture creating such series;

                  (6) to secure the Securities;

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

                  (8) to evidence and provide for the acceptance of appointment
         hereunder by a successor Trustee with respect to the Securities of one

         administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Section 611(b);

                  (9) to provide for any rights of the Holders of Securities of
         any series to require the repurchase of Securities of such series by
         the Company; or

                  (10) to cure any ambiguity, to correct or supplement any
         provision herein which may be inconsistent with any other provision

         Trustee, or to make any other provisions with respect to matters or
         questions arising under this Indenture; provided such action shall not
         materially and adversely affect the interests of the Holders of
         Securities of any series.

SECTION 902.      Supplemental Indentures with Consent of Holders

                  With the consent of the Holders of a majority in aggregate
principal amount of the outstanding Securities of all series affected by such
supplemental indenture (voting as one class), by Act of said Holders delivered
to the Company and the Trustee, the Company, when authorized by or pursuant to a
Board Resolution, the Guarantor and the Trustee may enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this indenture or
of modifying in any manner the rights of the Holders of Securities 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,

                                       56

<PAGE>

                  (1) change the Stated Maturity of the principal of, or any
         installment of interest, if any, on, any Security, or reduce the

         Section 513, except to increase any such percentage or to provide that
         certain other provisions of this Indenture cannot be modified or waived
         without the consent of the Holder of each Outstanding Security affected
         thereby; 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
         902, or the deletion of this proviso, in accordance with the
         requirements of Sections 611(b) and 901(8).

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.

                  It shall not be necessary for any Act of Holders under this
Section 902 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

                                       57

<PAGE>

                  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, if so required by the Trust Indenture Act, conform to the requirements of
the Trust Indenture Act as then in effect.

SECTION 906.      Reference in Securities to Supplemental Indentures

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

                                   ARTICLE TEN

                                    COVENANTS

SECTION 1001.     Payment of Principal. Premium, if any, and Interest

                  The Company covenants and agrees for the benefit of each
series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest and Additional Amounts, if any, on the Securities
of that series in accordance with the terms of the Securities and this
Indenture. An installment of principal of or interest on the Securities of a
series shall be considered paid on the date it is due if the Trustee or Paying
Agent holds at 11:00 a.m. (New York City time in the case of payments in US
Dollars and London time in the case of payments in Pounds Sterling) on that date
money deposited by the Company in immediately available funds and designated
for, and sufficient to pay, the installment in full.

                  Neither the Company, the Guarantor, nor any agent of the
Company or the Guarantor will have any responsibility or liability for any
aspect relating to payments made or to be made by the Book-Entry Depositary to
DTC in respect of the Securities of a series or the Book-Entry Interests. None
of the Company, the Trustee, the Book-Entry Depositary or any agent of any of
the foregoing will have any responsibility or liability for any aspect relating
to payments made or to be made by DTC on account of a Participant's or Indirect
Participant's ownership of an interest in the Book-Entry Interests or for
maintaining, supervising or reviewing any records relating to a Participant's
interests in the Book-Entry Interests.

SECTION 1002.     Maintenance of Office or Agency

                                       58

<PAGE>

                  The Company will maintain (i) in the Borough of Manhattan, The
City of New York, an office or agency where Securities of any series may be
presented or surrendered for payment, and where notices and demands to or upon
the Company in respect of the Securities of such series and this Indenture may
be served and if definitive Registered Securities have been issued, an office or
agency of a Transfer Agent where Securities may be surrendered for registration
of transfer or exchange, and (ii) an office or agency of a Paying Agent where
the Securities may be paid in Luxembourg so long as the Securities are listed on
the Luxembourg Stock Exchange and the rules of such exchange so require. The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of any such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fall to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, except that Bearer Securities of that series pursuant to Section 1001
may be presented at the place specified for the purpose pursuant to Section 301,
and the Company hereby appoints the Paying Agent 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 (in or outside of such Place of Payment) where the
Securities of one or more series and any appurtenant coupons (subject to Section
1001) may be presented or surrendered for any or all of such purposes, and may
from time to time rescind such designations; provided, however that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in each Place of Payment for any
series of Securities for such purposes. The Company will give prompt written
notice to the Trustee of any such designation and any change in the location of
any such other office or agency. The Company will at all times maintain at least
one Paying Agent which is located outside the United Kingdom for each series of
Securities.

SECTION 1003.     Money for Securities Payments to Be Held in Trust

                  If the Company shall at any time act as its own Paying Agent
with respect to any series of Securities, it will, on or before each due date of
the principal of, premium, if any, or interest, if any, 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, premium, if any, or
interest, if any, 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, no later than 11:00 a.m. (New York City time
in the case of payments in US Dollars and London time in the case of payments in
Pounds Sterling) on or prior to each due date of the principal of, premium, if
any, or interest, if any, on any Securities of that series, deposit with a
Paying Agent a sum in immediately available funds sufficient to pay the
principal, premium, if any, or interest so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or
interest.

                  Any Paying Agent appointed pursuant to Section 304 herein
shall:

                                       59

<PAGE>

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

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

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

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

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of, premium,
if any, or interest, if any, on any Security of any series and remaining
unclaimed for two years after such principal, premium, if any, or interest has
become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to
the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease.

SECTION 1004.     Limitation on Liens

                  If this covenant shall be made applicable to the Securities of
a particular series as contemplated by Section 301 hereof, the Company and the
Guarantor shall not, and shall not cause or permit any Significant Subsidiary
to, issue, assume or guarantee or permit to exist any notes, bonds, debentures
or other similar evidences of indebtedness, in each case for money borrowed
("Debt"), secured by a Lien upon any property or assets (other than cash) of the
Company, the Guarantor or such Significant Subsidiary, as applicable, without
effectively providing that the outstanding Securities (together with, if the
Guarantor so determines, any other indebtedness or obligation then existing or
thereafter created ranking equally with such Securities) shall be secured
equally and ratably with (or prior to) such Debt so long as such Debt shall be
so secured. The foregoing restriction on Liens will not, however, apply to:

Securities;

guarantee given in respect thereof, (B) such Lien is created or arises on or
before 90 days after the completion of such acquisition, construction or
creation and (C) such Lien is confined solely to the property so acquired,

Guarantor or a Significant Subsidiary incurred in connection with a specifically
identifiable project where the Lien relates to and is confined to a property or
properties (including, without limitation, shares or other rights of ownership
in the entities which own such property or project) involved in such project and
acquired by the Company, the Guarantor or a Significant Subsidiary after the
date of original issue of the Securities of any series and the recourse of the
creditors in respect of such Debt is limited to any or all of such project and
property (including as aforesaid);

                  (c) any Lien securing amounts (in respect of, for the
avoidance of doubt, taxes, assessments or governmental charges or claims) that
are not more than 90 days overdue or otherwise being contested in good faith;

                  (d) (i) rights of financial institutions to offset credit

Subsidiary or in connection with the issuance of letters of credit for the
benefit of the Company, the Guarantor and/or a Significant Subsidiary; (ii) any
Lien securing Debt of the Company, the Guarantor or a Significant Subsidiary

any Lien upon specific items of inventory or other goods and proceeds of the
Company, the Guarantor or a Significant Subsidiary securing obligations of the
Company, the Guarantor or a Significant Subsidiary in respect of bankers'
acceptances issued or created for the account of such person to facilitate the
purchase, shipment or storage of such inventory or other goods; (v) any Lien
incurred or deposits made securing the performance of tenders, bids, leases,
trade contracts (other than for borrowed money), statutory obligations, surety
bonds, appeal bonds, government contracts, performance bonds, return-of-money
bonds and other obligations of like nature incurred in the ordinary course of
business; (vi) any Lien created by the Company, the Guarantor or a Significant
Subsidiary under or in connection with or arising out of any pooling and
settlement agreements or pooling and settlement arrangements of the United
Kingdom electricity industry including, without limitation, the Pooling and
Settlement Agreement dated March 30, 1990, as amended, modified or supplemented
from time to time, or any transactions or arrangements entered into in
connection with hedging or management of risks relating to the electricity
industry in the United Kingdom; (vii) any Lien constituted by a right of set off
or right over a margin call account or any form of cash or cash collateral or

Significant Subsidiary, or any Liens on the property or assets of any
corporation or other entity existing at the time such corporation or other
entity becomes a Significant Subsidiary of the Guarantor and, in either such
case, is not created in anticipation of any such transaction (unless such Lien
is created to secure or provide for the payment of any part of the purchase
price of such corporation); (ii) any Lien on any property or assets existing at
the time of acquisition thereof and which is not created in anticipation of such
acquisition (unless such Lien was created to secure or provide for the payment
of any part of the purchase price of such property or assets); and (iii) any
Lien created or outstanding on or over any asset of any Person which becomes a
Significant Subsidiary on or after the date of the issuance of such Securities
when such Lien is created prior to the date on which such Person becomes a
Significant Subsidiary;

                  (g) (i) Liens required by any contract or statute in order to
permit the Company, the Guarantor or a Significant Subsidiary to perform any
contract or subcontract made by it with or at the request of a governmental
entity or any department, agency or instrumentality thereof, or to secure
partial, progress, advance or any other payments by the Company, the Guarantor
or a Significant Subsidiary to such governmental unit pursuant to the provisions
of any contract or statute; and (ii) any Lien securing industrial revenue,
development or similar bonds issued by or for the benefit of the Company, the
Guarantor or a Significant Subsidiary, provided that such industrial revenue,
development or similar bonds are nonrecourse to the Company, the Guarantor or
such Significant Subsidiary;

                  (h) (i) any Lien which arises pursuant to any order of
attachment, distraint or similar legal process arising in connection with court
proceedings and any Lien which secures the reimbursement obligation for any bond

in good faith and, if appropriate, by appropriate legal proceedings, or any Lien
in favor of a plaintiff or defendant in any action before a court or tribunal as
security for costs and/or other expenses; or (ii) any Lien arising by operation
of law or by order of a court or tribunal or any Lien arising by an agreement of
similar effect, including, without limitation, judgment liens; or

                  (i) any extension, renewal or replacement (or successive
extensions, renewals or replacements), as a whole or in part, of any Liens
referred to in the foregoing clauses, for amounts not exceeding the principal
amount of the Debt secured by the Lien so extended, renewed or replaced,
provided that such extension, renewal or replacement Lien is limited to all or a
part of the same property or assets that were covered by the Lien extended,
renewed or replaced (plus improvements on such property or assets).

                  Notwithstanding the foregoing, the Company, the Guarantor or a
Significant Subsidiary may create or permit to subsist Liens over any property

                                       62
<PAGE>

(excluding therefrom the amount of Debt secured by Liens set forth in clauses
(a) through (i), inclusive, above) does not exceed 10% of Consolidated Net
Tangible Assets.

                  Nothing contained in this Indenture in any way restricts or
prevents the Company or any Subsidiary from incurring any Debt.

SECTION 1005.     Limitation on Sale and Lease-Back Transactions

contained in Sections 1001 to 1008, stating whether or not he has knowledge of
any such default without regard to any period of grace or requirement of notice
and, if so, specifying each such default of which such signer has knowledge and

SECTION 1009.     Payment of Additional Amounts

                  Unless the Securities of a particular series otherwise
provide, all payments of principal and interest (including payments of discount
and premium, if any) with respect to the Securities of a particular series shall
be made free and clear of, and without withholding or deduction for or on
account of, any present or future taxes, duties, assessments or governmental
charges of whatever nature imposed, levied, collected, withheld or assessed by
or within a Taxing Jurisdiction or by or within any political subdivision
thereof or any authority therein or thereof having power to tax ("Gross-Up
Taxes"), unless such withholding or deduction is required by law. In the event
of any such withholding or deduction, the Company or the Guarantor, as the case
may be, shall pay to the Holder of such Securities such additional amounts in
respect of such withholding or deduction as are necessary so that such Holder
receives the amount that would have been due to such Holder in the absence of
such withholding or deduction ("Additional Amounts"), except that no such
Additional Amounts shall be payable:

                                       64

<PAGE>

                  (a) to, or to a Person on behalf of, a Holder who is liable
for such Gross-Up Taxes with respect to the Securities or any Guarantee, by
reason of such Holder having some connection with the relevant Taxing
Jurisdiction (including being a citizen or resident or national of, or carrying
on a business or maintaining a permanent establishment in, or being physically
present in, such Taxing Jurisdiction) other than the mere holding of a Security
or the receipt of principal and interest (including payments of discount and
premium, if any) in respect thereof or in respect of the Guarantee; or

                  (b) to, or to a Person on behalf of, a Holder who presents a
Security (where presentation is required) for payment more than 30 days after
the Relevant Date except to the extent that such Holder would have been entitled
to such Additional Amounts on presenting such Security for payment on the last
day of such period of 30 days;

                  (c) to, or to a Person on behalf of, a Holder who presents a
Security (where presentation is required) in a Taxing Jurisdiction or, so long
as the Securities of such series are listed on the Luxembourg Stock Exchange, in
Luxembourg;

                  (d) to, or to a Person on behalf of, a Holder who would not be
liable or subject to the withholding or deduction by making a declaration of
non-residence or similar claim for exemption to the relevant tax authority; or

                  (e) to, or to a Person on behalf of, a Holder of a Registered
Security that is not a Global Security issued pursuant to the request of any
beneficial owner of interests in such Securities (an "Optional Definitive
Security Request") during the continuance of an Event of Default if such Holder
(or any predecessor Holder) was an owner requesting that such Registered
Securities be so issued.

                  Such Additional Amounts will also not be payable where, had
the beneficial owner of the Security (or any interest therein) been the Holder
of the Security, he would not have been entitled to payment of Additional
Amounts by reason of any one or more of clauses (a) through (e) above. If the
Company or the Guarantor, as applicable, shall determine that Additional Amounts
will not be payable for any of the foregoing reasons, the Company or the
Guarantor, as applicable, will inform such Holder promptly after making such
determination setting forth the reason(s) therefor.

                  Reference in this Indenture or any Securities to principal,
interest, discount or premium in respect of the Securities (or any payments
pursuant to any Guarantee) shall be deemed also to refer to any Additional
Amounts which may be payable as set forth in this Indenture or in the
Securities.

                  At least 10 Business Days prior to the first Interest Payment
Date (and at least 10 Business Days prior to each succeeding Interest Payment
Date if there has been any change with respect to the matters set forth in the
below-mentioned Officers' Certificate), the Company will furnish to the Trustee
and any Paying Agent an Officers' Certificate instructing the Trustee and any
Paying Agent whether payments of principal of, or premium, if any, or interest
on, the Securities due on such Interest Payment Date shall be without deduction

                                       65
<PAGE>

or withholding for or on account of any Gross-Up Taxes. If any such deduction or
withholding shall be required, prior to such Interest Payment Date the Company
will furnish the Trustee and any Paying Agent with an Officers' Certificate
which specifies the amount, if any, required to be withheld on such payment to
Holders and certifies that the Company shall pay such withholding or deduction.
The Company covenants to indemnify the Trustee and any Paying Agent for, and to
hold the Trustee and any Paying Agent harmless against, any loss, liability or
expense reasonably incurred without negligence, willful misconduct or bad faith
on its part, arising out of or in connection with actions taken or omitted by
the Trustee or any Paying Agent in reliance on any Officers' Certificate
furnished pursuant to this paragraph. Any Officers' Certificate required by this
Section 1009 to be provided to the Trustee and any Paying Agent shall be deemed
to be duly provided if telecopied to the Trustee and such Paying Agent.

                  The Company shall furnish to the Trustee the official receipts
(or a certified copy of the official receipts) evidencing payment of Gross-Up
Taxes. Copies of such receipts shall be made available to the Holders of the
Securities upon request.

SECTION 1010.     Copies Available to Holders

                  Copies of this Indenture shall be available for inspection by
the Holders on a Business Day during normal business hours at the principal
office of the Company and at the Corporate Trust Office. In addition, if the
Securities of any series are listed on the London Stock Exchange, the Luxembourg
Stock Exchange or any other stock exchange located outside the United States and
such stock exchange shall so require, copies of this Indenture, the Deposit
Agreement, the Letter of Representations, the memorandum and articles of
association of the Company and the most recent publicly available annual report
of the Guarantor shall be made available for inspection by the Holders of such
Securities on a Business Day during normal business hours at the offices of the
paying agents and at the office of the listing agent required to be maintained
by such exchange for so long as the Securities of such series are outstanding
and are listed on such stock exchange.

                                 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 in or contemplated by Section 301 for Securities of any
series) in accordance with this Article Eleven.

SECTION 1102.     Election to Redeem: Notice to Trustee
                  The election of the Company to redeem any Securities shall be
authorized by a Board Resolution and evidenced by an Officers' Certificate. In
case of any redemption at the election of the Company of less than all the
Securities of any series, the Company shall, at least 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

<PAGE>

the principal amount of Securities of such series to be redeemed. In the case of
any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, or pursuant to an election by 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, 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 or of a denomination larger
than the minimum authorized denomination for Securities of that series.

                  Securities shall be excluded from eligibility for selection
for redemption if they are identified by certificate number in a written
statement signed by an authorized officer of the Company and delivered to the
Security Registrar at least 30 days prior to the Redemption Date as being owned
of record and beneficially by, and not pledged or hypothecated by either (a) the
Company or (b) an entity specifically identified in such written statement which
is an Affiliate of the Company.

                  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.
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

                  Unless otherwise specified in a supplemental indenture with
respect to a series of Securities, notice of redemption shall be given not less
than 30 days nor more than 60 days prior to the Redemption Date to each Holder
of Securities to be redeemed.

                  All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price,

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

                                       67

<PAGE>

                  (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

                  On or prior to any Redemption Date, the Company shall deposit
with the Trustee or with a Principal Paying Agent (or, if the Company is acting
as its own Paying Agent, segregate and hold in trust as provided in Section
1003) an amount of money 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 (to the extent that
such amounts are not already on deposit at such time in accordance with the
provisions of Sections 401, 403 or 1007).

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 and unpaid 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 and unpaid 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, and in the case of Registered 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 (including any Global 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 upon written direction shall

                                       68
<PAGE>

authenticate and deliver to the Holder of such Security without service charge,
a new Security or Securities of the same series, of any authorized denomination
as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the security so
surrendered; provided, that if a Global Security is so surrendered, the new
Global Security shall be in a denomination equal to the unredeemed portion of
the principal of the Global Security so surrendered.

SECTION 1108.     Optional Redemption in the Event of Chance in Taxing Jurisdic-
tion Tax Treatment

                  The Securities of any series may be redeemed at the election
of the Company, as a whole, but not in part, by the giving of notice as provided
in Section 1104, at a price equal to the outstanding principal amount thereof,
together with Additional Amounts, if any, and accrued interest, if any, to the
Redemption Date, if (a) the Company or the Guarantor satisfies the Trustee that
it has or will become obligated to pay Additional Amounts on the Securities of
such series, as a result of either (x) any change in, or amendment to, the laws
or regulations of a Taxing Jurisdiction, or any change in the application or
interpretation of such laws or regulations, which change or amendment becomes
effective (subject to Section 801) on or after the date of original issuance of
the Securities of such series, or (y) the issuance of definitive Registered
Securities as the result of (i) DTC having notified the Company and the
Book-Entry Depositary that it is unable or unwilling to continue to hold the
Book-Entry Interests or at any time ceases to be a "clearing agency" registered
as such under the Exchange Act and, in either case, a successor is not appointed
by the Company within 120 days, (ii) the Book-Entry Depositary having notified
the Company that it is unwilling or unable to continue as Book-Entry Depositary
with respect to the Global Securities of such series and a successor Book-Entry
Depositary is not appointed within 120 days or (iii) an Optional Definitive
Security Request and (b) such obligation cannot be avoided by the Company or the
Guarantor taking reasonable measures available to it; provided, however, that no
such notice of redemption shall be given earlier than 90 days prior to the
earliest date on which the Company or the Guarantor would be obligated to pay
such Additional Amounts were a payment in respect of the Securities then due.
Prior to the publication of any notice of redemption of such Securities pursuant
to this Indenture, the Company or the Guarantor will deliver to the Trustee an
Officers' Certificate stating that the obligation to pay such Additional Amounts
cannot be avoided by the Company or the Guarantor taking reasonable measures
available to it, and the Trustee shall accept such certificate as sufficient
evidence of the condition precedent set forth in clause (b) above, and such
certificate shall be conclusive and binding on the Holders of the Securities of
such series.

                                 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.

                                       69

<PAGE>

                  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

                  In lieu of making all or any part of any mandatory sinking
fund payment with respect to any series of Securities in cash, the Company may
at its option (a) deliver to the Trustee Securities of such series theretofore
purchased or otherwise acquired (except upon redemption pursuant to the
mandatory sinking fund) by the Company or receive credit for Securities of such
series (not previously so credited) theretofore purchased or otherwise acquired
(except as aforesaid) by the Company and delivered to the Trustee for
cancellation pursuant to Section 310, (b) receive credit for optional sinking
fund payments (not previously so credited) made pursuant to this Section 1202,
or (c) receive credit for Securities of such series (not previously so credited)
redeemed by the Company through any optional redemption provision contained in
the terms of such series. Securities so delivered or credited shall be received
or credited by the Trustee at the sinking fund Redemption Price specified in
such Securities.

SECTION 1203.     Redemption of Securities for Sinking Fund

                  Not less than 30 days prior to each sinking fund payment date
for any series of Securities, the Company will deliver to the Trustee an
Officers' Certificate specifying (a) the amount of the next ensuing sinking fund
payment for that series pursuant to the terms of that series, (b) whether or not
the Company intends to exercise its right, if any, to make an optional sinking
fund payment with respect to such series on the next ensuing sinking fund
payment date and, if so, the amount of such optional sinking fund payment, and
(c) 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 will also
deliver to the Trustee any Securities to be so delivered. Such written statement
shall be irrevocable and upon its receipt by the Trustee the Company shall
become unconditionally obligated to make all the cash payments or payments
therein referred to, if any, on or before the next succeeding sinking fund
payment date. Failure of the Company, on or before any such 30th day, to deliver
such written statement and Securities specified in this paragraph, if any, shall
not constitute a default but shall constitute, on and as of such date, the
irrevocable election of the Company (i) that the mandatory sinking fund payment
for such series due on the next succeeding sinking fund payment date shall be
paid entirely in cash without the option to deliver or credit Securities of such
series in respect therefor and (ii) that the Company will make no optional
sinking fund payment with respect to such series as provided in this Section
1203.

                  Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly

                                       70
<PAGE>

given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1105, 1106 and 1107.

                  The Trustee shall not redeem or cause to be redeemed any
Security of a series with sinking fund moneys or mail any notice of redemption
of Securities of such series by operation of the sinking fund during the
continuance of a default in payment of interest with respect to Securities of
that series or an Event of Default with respect to the Securities of that series
except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided that it shall have received from the Company a sum
sufficient for such redemption. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default,
shall occur, and any moneys thereafter paid into the sinking fund, shall, during
the continuance of such default or Event of Default, be deemed to have been
collected under Article Five and held for the payment of all such Securities. In
case such Event of Default shall have been waived as provided in Section 513 or
the default or Event of Default cured on or before the 30th day preceding the
sinking fund payment date, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section 1203 to the
redemption of such Securities.

Trustee of the taking of any action at a meeting of Holders by the Holders of
the percentage in aggregate principal amount of the Securities specified in this

binding upon such Holder and upon all future Holders and owners of such
Securities and of any Securities issued in exchange therefore, in lieu thereof
or upon transfer thereof, irrespective of whether or not any notation in regard
thereto is made upon such Securities. Any action taken by the Holders of the
percentage in aggregate principal amount of the Holders specified in this

SECTION 1401.     Applicability of Article; Unconditional Guarantee

                  If, pursuant to Section 301, provision is made for the
Guarantee of the Securities of any series by the Guarantor, then the provisions
of this Article Fourteen, with such modifications thereto as may be specified

injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby, and (y) in the event of any acceleration of such
obligations as provided in Article Five, such obligations (whether or not due
and payable) shall forthwith become due and payable by the Guarantor for the
purpose of any Guarantee.

                  The Company agrees that the proceeds from the issuance of the
Securities of any series shall be loaned, directly or indirectly, to the
Guarantor or any wholly-owned Subsidiary and that any such loan shall be
evidenced by promissory notes. The Company agrees that any payment to the
Holders by the Guarantor under the Guarantee with respect to the Securities of
any series shall constitute an indirect payment by the Guarantor on, and shall
reduce the principal of and premium, if any, and interest on, such promissory
notes.

status as such stockholder, officer, director, employee or incorporator.

                  The Guarantee set forth in this Section 1401 shall not be

agreement, covenant, term or condition relating to the Securities to be

any other sums payable under the terms of the Securities or the extension of
time for the performance of any other obligation under, arising out of, or in
connection with, the Securities;

                  (c) any failure, omission, delay or lack of diligence on the
part of the Holders to enforce, assert or exercise any right, privilege, power
or remedy conferred on the Holders pursuant to the terms of the Securities, or
any action on the part of the Company granting indulgence or extension of any
kind;

                  (f) the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or

                  (g) any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor (other than,
subject to Section 1401, payment of the underlying obligation), it being the
intent of this Article Fourteen that the obligations of the Guarantor hereunder
shall be absolute and unconditional under any and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain the
consent of, the Guarantor with respect to the happening of any of the foregoing.

SECTION 1404.     Execution of Guarantee

                  To evidence its guarantee to the Holders specified in Section

substantially the form set forth in Section 204 to be endorsed on each Security
authenticated and delivered by the Trustee. The Guarantor hereby agrees that its
Guarantee set forth in Section 1401 shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation of such
Guarantee. Each such notation of the Guarantee shall be signed on behalf of the
Guarantor, by a director or officer, prior to the authentication of the Security
on which it is endorsed, and the delivery of such Security by the Trustee, after
the due authentication thereof by the Trustee hereunder, shall constitute due
delivery of the Guarantee on behalf of the Guarantor. Such signature upon the
notation of the Guarantee may be a manual or facsimile signature of any present,
past or future such director or officer and may be imprinted or otherwise
reproduced below the notation of the Guarantee, and in case any such director or
officer who shall have signed the notation of the Guarantee shall cease to be
such director or officer before the Security on which such notation is endorsed
shall have been authenticated and delivered by the Trustee or disposed of by the
Company, such Security nevertheless may be authenticated and delivered or
disposed of as though the person who signed the notation of the Guarantee had
not ceased to be such director or officer of the Guarantor.

Guarantor under this Article Fourteen with respect to any series of Securities.
Furthermore, the Guarantor shall not (except to the extent required by mandatory
provisions of law) be entitled to enforce or exercise any rights which it may
acquire by way of any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Article Fourteen with respect to a series of
Securities if, at any time of such payment, any amounts are due and unpaid under
such series of Securities. If any amount shall be paid to the Guarantor in
violation of the preceding sentence, the Guarantor agrees to hold such amount in
trust for the Holders and to pay over such amount to the Holders.

payments pursuant to the terms of the Securities notwithstanding the occurrence
of any event referred to in subsections (a) through (g), inclusive, of Section

and agrees, for the benefit of the Holders from time to time of the Securities
and the Trustee, that any civil legal action, suit or proceeding against it with
respect to its obligations, liabilities or any other matter arising out of or in
connection with this Indenture, the Securities or any Guarantee may be brought
in the Supreme Court of New York, New York County or the United States District
Court for the Southern District of New York and any appellate court from either
thereof and, until amounts due and to become due in respect of the Securities or
any Guarantee have been paid, hereby irrevocably consents and submits to the
non-exclusive jurisdiction of each such court in personam, generally and

consents with such authorities as may be required to irrevocably evidence such
agreement.

office at 111 Eighth Avenue, New York, New York 10011, as its designee,

summonses, notices and documents which may be served in any legal action, suit

or state court. If for any reason such designee, appointee and agent hereunder
shall cease to be available to act as such, each of the Company and the

                                       76
<PAGE>

Guarantor agrees to designate a new designee, appointee and agent in the Borough
of Manhattan, The City of New York on the terms and for the purposes of this
Section 1501 satisfactory to the Trustee. Each of the Company and the Guarantor
further hereby irrevocably consents and agrees to the service of any and all
legal process, summonses, notices and documents in any legal action, suit or
proceeding against the Company or the Guarantor by serving a copy thereof upon
the relevant agent for service of process referred to in this Section 1501
(whether or not the appointment of such agent shall for any reason prove to be
ineffective or such agent shall accept or acknowledge such service) or by
mailing copies thereof by registered or certified air mail, postage prepaid, to
each of the Company or the Guarantor at its address specified in or designated
pursuant to this Indenture. Each of the Company and the Guarantor agrees that
the failure of any such designee, appointee and agent to give any notice of such
service to it shall not impair or affect in any way the validity of such service
or any judgment rendered in any action or proceeding based thereon. Nothing
herein shall in any way be deemed to limit the ability of the holders of the
Securities and the Trustee, to serve any such legal process, summons, notices
and documents in any other manner permitted by applicable law or to obtain
jurisdiction over the Company or the Guarantor or to bring legal actions, suits
or proceedings against the Company or the Guarantor in such other jurisdictions,
and in such manner, as may be permitted by applicable law. Each of the Company
and the Guarantor irrevocably and unconditionally waives, to the fullest extent
permitted by law, any objection which it may now or hereafter have to the laying
of venue of any of the aforesaid actions, suits or proceedings arising out of or
in connection with this Indenture brought in the Supreme Court of New York, New
York County or the United States District Court for the Southern District of New
York and any appellate court from either thereof and hereby further irrevocably
and unconditionally waives and agrees not to plead or claim in any such court
that any such action, suit or proceeding brought in any such court has been
brought in an inconvenient forum.

                  (c) To the extent that the Company or the Guarantor may in any
jurisdiction claim for itself or its assets immunity (to the extent such
immunity may now or hereafter exist, whether on the grounds of sovereign
immunity or otherwise) from suit, execution, attachment (whether in aid of
execution, before judgment or otherwise) or other legal process (whether through
service or notice or otherwise), and to the extent that in any such jurisdiction
there may be attributed to itself or its assets such immunity (whether or not
claimed), the Company and the Guarantor irrevocably agrees with respect to any
matter arising under the Indenture for the benefit of the Holders from time to
time of the Securities, not to claim, and irrevocably waives, such immunity to
the full extent permitted by the laws of such jurisdiction.

                  (d) If for the purpose of obtaining a judgment or order in any
court it is necessary to convert a sum due hereunder to the holder of any
Security from U.S. dollars into another currency, each of the Company and the
Guarantor agrees, and each holder by holding such Security will be deemed to
have agreed, to the fullest extent that they may effectively do so, that the
rate of exchange used shall be that at which in accordance with normal banking
procedures such Holder could purchase U.S. dollars with such other currency in
The City of New York on the Business Day preceding the day on which final
judgment is given.

                  (e) The obligations of the Company and the Guarantor in
respect of any sum payable by it to the holder of a Security shall,
notwithstanding any judgment or order in a currency (the "judgment currency")
other than U.S. dollars, be discharged only to the extent that on the Business

                                       77
<PAGE>

Day following receipt by the Holder of such security of any sum, adjudged to be
so due in the judgment currency, the Holder of such Security may in accordance
with normal banking procedures purchase U.S. dollars with the judgment currency;
if the amount of U.S. dollars so purchased is less than the sum originally due
to the holder of such Security in the judgment currency (determined in the
manner set forth in the preceding paragraph), each of the Company and the
Guarantor agrees, as a separate obligation and notwithstanding any such
judgment, to indemnify the Holder of such Security against such loss, and if the
amount of the U.S. dollars so purchased exceeds the sum originally due to the
Holder of such Security, such Holder agrees to remit to the Company or the
Guarantor such excess, provided that such Holder shall have no obligation to
remit any such excess as long as the Company or the Guarantor shall have failed
to pay such Holder any obligations due and payable under such Security, in which
case such excess may be applied to such obligations of the Company or the
Guarantor under such Security in accordance with the terms thereof. The
foregoing indemnity shall constitute a separate and independent obligation of
the Company and the Guarantor and shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid.

SECTION 1502.     Counterparts

                  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.

                  (c) The rate of interest payable from time to time through the
Initial Reset Date in respect of the Senior Notes for any Interest Accrual
Period (the "Rate of Interest") will be determined on the basis of the following
provisions:

                  (i) on the first day of such Interest Accrual Period (the
         "Interest Determination Date"), the Agent Bank will determine the
         Screen Rate at or about 11:00 a.m. (London time) on the Interest
         Determination Date. If such Screen Rate is unavailable, the Agent Bank
         will request the principal London office of each of the Reference Banks
         to provide the Agent Bank with its offered quotation to leading banks
         for Sterling deposits in the London interbank market for such Interest
         Accrual Period at or about 11:00 a.m. (London time) on the Interest
         Determination Date. The Rate of Interest for such Interest Accrual
         Period shall be such Screen Rate plus 0.805% per annum (the "Margin")
         or, if such Screen Rate is unavailable, the arithmetic average (rounded
         upwards if necessary to the nearest 1/16th of 1%) of the offered
         quotations provided by the Reference Banks (excluding the highest and
         lowest (or, in either case, if more than one, then only one of them) of
         such quotations) plus the Margin;

                  (ii) if on the Interest Determination Date such Screen Rate is
         unavailable and only four of the Reference Banks provide offered
         quotations, the Rate of Interest for such Interest Accrual Period shall
         be determined in accordance with the provisions of paragraph (i) above
         on the basis of the offered quotations of those Reference Banks
         providing the offered quotations (excluding the highest and lowest of
         such quotations as provided in paragraph (i) above);

                  (iii) if on the Interest Determination Date such Screen Rate
         is unavailable and only two or three of the Reference Banks provide
         offered quotations, the Rate of Interest for such Interest Accrual
         Period shall be determined in. accordance with the provisions of
         paragraph (i) above on the basis of the offered quotations of those
         Reference Banks providing the offered quotations (but without excluding
         the highest and lowest of such quotations as provided in paragraph (i)
         above); and

                  (iv) if on the Interest Determination Date such Screen Rate is
         unavailable and only one or none of the Reference Banks provides an
         offered quotation, then the Rate of Interest for such Interest Accrual
         Period shall be (a) the Rate of Interest in effect for that Interest
         Accrual Period to which paragraph (i), (ii) or (iii) above shall have
         applied which last preceded such Interest Accrual Period or (b) if
         determinable and if higher, the Reserve Interest Rate (as defined
         below). The "Reserve Interest Rate" shall be the rate per annum which
         the Agent Bank determines to be either (A) the arithmetic average
         (rounded upward if necessary to the nearest 1/16th of 1%) of the
         Sterling lending rates for loans in an amount approximately equal to
         the principal amount of the Senior Notes which London banks selected by
         the Agent Bank are quoting, at or about 11:00 a.m. (London time) on the
         Interest Determination Date, for such Interest Accrual Period, to the
         Reference Banks or those of them (being at least two in number) to
         which the quotations are, in the opinion of the Agent Bank, being so
         made plus the Margin or (B) if the Agent Bank cannot determine the
         arithmetic average, the lowest Sterling lending rate which four London
         banks selected by the Agent Bank are quoting, on the Interest
         Determination Date, for such Interest Accrual Period, to leading
         European banks plus the Margin.

                  (d) The Agent Bank shall, as soon as practicable after 11:00
a.m. (London time) on each Interest Determination Date, but in no event later
than the third Business Day thereafter, determine the Sterling amount payable in
respect of interest on the principal amount of the Senior Notes (the "Interest
Amount") for the relevant Interest Accrual Period. The Interest Amount for any
Interest Accrual Period shall be determined by (i) applying the Rate of Interest
for such Interest Accrual Period to the principal amount of the Senior Notes and
(ii) multiplying that amount by the actual number of days in such Interest
Accrual Period divided by 365 (or if such Interest Accrual Period ends after
February 28 in a leap year, 366) expressed as a decimal and rounded upward if
necessary to the nearest 1/16th of 1%.

                  (e) All determinations, certificates, calculations, quotations
and decisions given, expressed, made or obtained for the purposes of the pro-
visions of this Section 202, whether by the Reference Banks (or any of them) or
the Agent Bank, will (in the absence of willful default, bad faith or manifest
error) be binding on the Company, the Guarantor, the Reference Banks, the Agent
Bank, the Paying Agent and all holders of Senior Notes, and (in the absence as
referred to above) no liability to the Company, the Guarantor or the holders of
Senior Notes shall attach to the Reference Banks or the Agent Bank in
connection with the exercise or non-exercise by them of their powers, duties and
discretions under this Section 202.

                  SECTION 203.      Conversion Event.

                  (a) Upon the occurrence of a Conversion Event, then
automatically (i) the aggregate principal amount of the Senior Notes shall
convert to $250,000,000 effective from the date of the immediately preceding
Interest Payment Date prior to the occurrence of such Conversion Event, (ii) the
interest rate on the Senior Notes shall convert to 8.25% per annum effective
from the date of the immediately preceding Interest Payment Date prior to the
occurrence of such Conversion Event and (iii) such interest rate shall be
calculated on the basis of a 360-day year of twelve 30-day months.

                  (b) Notwithstanding anything in Section 502 of the Original
Indenture to the contrary, the aggregate principal amount of the Outstanding
Senior Notes that shall become immediately due and payable upon a Conversion
Event shall be as set forth in clause (i) of Section 203(a) hereof.

                  (c) Upon a Conversion Event, the Trustee shall provide notice
by first class mail within 15 calendar days after the occurrence of such
Conversion Event (or if the declaration of acceleration relating to such
Conversion Event shall have been given by holders of the Senior Notes, after the
date on which the Trustee shall receive notice of such acceleration) of the
information set forth in this Section 203 to any securities exchange on which
the Senior Notes may then be listed and to the holder of the Senior Notes.

                  SECTION 204.      Interest after Initial Reset Date.

                  (a) Interest Rate to Maturity.

                  (i) In accordance with the procedures established in the
Remarketing Agreement and subject to Section 212, the interest rate in effect
with respect to the Senior Notes immediately prior to the Initial Reset Date
shall be reset on the Initial Reset Date to equal the Interest Rate to Maturity,

                                      -7-
<PAGE>

which shall be effective from and including the Initial Reset Date to but
excluding the final maturity of the Senior Notes, unless the Company shall
exercise the Floating Rate Option in accordance with paragraph (b) of this
Section 204. If the Company shall have so exercised the Floating Rate Option,
then the Floating Period Interest Rate shall be reset in accordance with the
Remarketing Agreement on the Reset Date corresponding to the Floating Rate
Period Termination Date to equal the Interest Rate to Maturity, which shall be
effective from and including such Reset Date to but excluding the final maturity
of the Senior Notes.

                  (ii) During the period from and including the Fixed Rate Reset
Date to but excluding the final maturity of the Senior Notes, interest on the
Senior Notes shall accrue on the principal amount of the Senior Notes at the
Interest Rate to Maturity and shall be payable semi-annually on each Interest
Payment Date, commencing with the first such Interest Payment Date following the
Fixed Rate Reset Date; provided, however, that, if any such Interest Payment
Date is not a Business Day, then payment of interest payable on such date will
be made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay). Interest on the Senior
Notes from the Fixed Rate Reset Date shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.

                  (b) Floating Rate Period.

Remarketing Agreement and subject to Section 212, if the Company exercises the
Floating Rate Option no later than the seventh Business Day prior to the
Floating Rate Spread Determination Date by providing notice to the Trustee and
Remarketing Agent, then the Senior Notes shall bear interest at the Floating
Period Interest Rate for each Floating Rate Reset Period in the Floating Rate
Period.

                  (ii) During each Floating Rate Reset Period in the Floating
Rate Period, interest on the Senior Notes shall accrue on the Floating Rate
Purchase Price at the Floating Period Interest Rate for such Floating Rate Reset
Period and shall be payable quarterly on each Interest Payment Date, commencing
with the first such Interest Payment Date following the Initial Reset Date. The
Interest Amount for such Floating Rate Reset Period shall be determined by (A)
applying the Floating Period Interest Rate for such Floating Rate Reset Period
to the Floating Rate Purchase Price and (B) multiplying that amount by the
actual number of days in such Floating Rate Reset Period divided by 365 (or, if
such Floating Rate Reset Period ends after February 28 in a leap year, 366)
expressed as a decimal and rounded upward if necessary to the nearest 1/16th of
1%.

                  (c) Notice.

                  Subject to Section 212, the Remarketing Agent shall notify the

incorporated under the laws of the Cayman Islands (herein called the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to the bearer upon
surrender hereof, the principal sum of (pound)____________* on February 15,
2020, and to pay interest thereon at the rate or rates per annum described
herein from February 16, 2000, or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, semi-annually on February 15

Date and thereafter subject to the terms and conditions set forth herein, at the
interest rate or rates determined by the Remarketing Agent in accordance with
the procedures set forth on the reverse hereof until the principal hereof is
paid or made available for payment. The interest so payable, and punctually paid
or duly provided for, on any Interest Payment Date will, as provided in such
Indenture, be paid to the bearer on such Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the bearer on such Interest Payment Date and will be paid to the
bearer hereof at the time of payment of such Defaulted Interest or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.
------------------------------

      * Reference is made to (i) Schedule A attached hereto with respect to
            decreases and increases in the aggregate principal amount of
            Securities evidenced by this certificate and (ii) the other
            provisions of this Security providing for the conversion to a US
            Dollar-denominated Security.

                                      A-2

<PAGE>

                 The per annum interest rate on the Securities for each
Interest Accrual Period through the Initial Reset Date will be reset
semi-annually based on procedures set forth below and established in the
Indenture; provided, however, that upon the occurrence of a Conversion Event,
this Security will convert to a US Dollar-denominated Security as provided in
the Indenture.

                  The rate of interest payable from time to time through the
Initial Reset Date in respect of this Security, for any Interest Accrual Period
(the "Rate of Interest") will be determined on the basis of the following
provisions:

                  (i) on the first day of such Interest Accrual Period (the
         "Interest Determination Date"), the Agent Bank will determine the
         Screen Rate for six-month Sterling deposits at or about 11:00 a.m.
         (London time) on the Interest Determination Date. If such Screen Rate
         is unavailable, the Agent Bank will request the principal London office
         of each of the Reference Banks to provide the Agent Bank with its
         offered quotation to leading banks for Sterling deposits in the London
         interbank market for such Interest Accrual Period at or about 11:00
         a.m. (London time) on the Interest Determination Date. The Rate of
         Interest for such Interest Accrual Period shall be such Screen Rate
         plus 0.805% per annum (the "Margin") or, if such Screen Rate is
         unavailable, the arithmetic average (rounded upwards if necessary to
         the nearest 1/16th of 1%) of the offered quotations provided by the
         Reference Banks (excluding the highest and lowest (or, in either case,
         if more than one, then only one of them) of such quotations) plus the
         Margin;

                  (ii) if on the Interest Determination Date such Screen Rate is
         unavailable and only four of the Reference Banks provide offered
         quotations, the Rate of Interest for such Interest Accrual Period shall
         be determined in accordance with the provisions of paragraph (i) above
         on the basis of the offered quotations of those Reference Banks
         providing the offered quotations (excluding the highest and lowest of
         such quotations as provided in paragraph (i) above);

                  (iii) if on the Interest Determination Date such Screen Rate
         is unavailable and only two or three of the Reference Banks provide
         offered quotations, the Rate of Interest for such Interest Accrual
         Period shall be determined in accordance with the provisions of
         paragraph (i) above on the basis of the offered quotations of those
         Reference Banks providing the offered quotations (but without excluding
         the highest and lowest of such quotations as provided in paragraph (i)
         above); and

                  (iv) if on the Interest Determination Date such Screen Rate is
         unavailable and only one or none of the Reference Banks provides an
         offered quotation, then the Rate of Interest for such Interest Accrual
         Period shall be (a) the Rate of Interest in effect for that Interest
         Accrual Period to which paragraph (i), (ii) or (iii) above shall have
         applied which last preceded such Interest Accrual Period or (b) if
         determinable and if higher, the Reserve Interest Rate (as defined
         below). The "Reserve Interest Rate" shall be the rate per annum which
         the Agent Bank determines to be either (A) the arithmetic average
         (rounded upward if necessary to the nearest 1/16th of 1%) of the
         Sterling lending rates for loans in an amount approximately equal to
         the principal amount of the Securities which London banks selected by
         the Agent Bank are quoting, at or about 11:00 a.m. (London time) on the
         Interest Determination Date, for such Interest Accrual Period, to the

                                      A-3

<PAGE>

         Reference Banks or those of them (being at least two in number) to
         which the quotations] are, in the opinion of the Agent Bank, being so
         made plus the Margin or (B) if the Agent Bank cannot determine the
         arithmetic average, the lowest Sterling lending rate which four London
         banks selected by the Agent Bank are quoting, on the Interest
         Determination Date, for such Interest Accrual Period, to leading
         European banks plus the Margin.

                  The Interest Amount shall be determined by (i) applying the
Rate of Interest for such Interest Accrual Period to the principal amount of the
Securities and (ii) multiplying that amount by the actual number of days in such
Interest Accrual Period divided by 365 (or if such Interest Accrual Period ends
after February 28 in a leap year, 366) expressed as a decimal and rounded upward
if necessary to the nearest 1/16th of 1%.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof, relating to the interest reset and
remarketing mechanics of this Security after the Initial Reset Date.

                  All payments in respect of this Security and all payments made
pursuant to the Guarantee of this Security shall be made in immediately
available funds at or through the office or agency of the Company maintained for
that purpose in the Borough of Manhattan, The City of New York, and for so long
as this Security shall be listed on the Luxembourg Stock Exchange, in
Luxembourg, in such coin or currency of the United Kingdom or the United States
of America, as the case may be, as at the time of payment is legal tender for
the payment of public and private debt. The Trustee shall make
Sterling-denominated payments on the Senior Notes through a London-based account
of the Trustee.

                  All payments of principal of, and premium, if any, and
interest in respect of this Security and all payments made pursuant to the
Guarantee of this Security shall be made free and clear of, and without
withholding or deduction for or on account of any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed, levied,
collected, withheld or assessed by or within a Taxing Jurisdiction or by or
within any political subdivision thereof or any authority therein or thereof
having power to tax ("Gross-Up Taxes"), unless such withholding or deduction is
required by law. In the event of any such withholding or deduction, the Company
or the Guarantor, as the case may be, shall pay to the Holder such additional
amounts in respect of such withholding or reduction as are necessary so that the
Holder receives the amount that would have been due in the absence of such
withholding or deduction ("Additional Amounts"), except that no such Additional
Amounts shall be payable:

                  (a) to, or to a Person on behalf of, a Holder who is Liable
         for such Gross-Up Taxes in respect of this Security or the Guarantee of
         this Security by reason of such Holder or beneficial owner having some
         connection with the relevant Taxing Jurisdiction (including being a
         citizen or resident or national of, or carrying on a business or
         maintaining a permanent establishment in, or being physically present
         in, such Taxing Jurisdiction) other than the mere holding of this
         Security or the receipt of principal of, and premium, if any, and
         interest in respect thereon or in respect of the Guarantee of this
         Security;

                                      A-4

<PAGE>

                  (b) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) for payment more than 30
         days after the Relevant Date except to the extent that the Holder would
         have been entitled to such Additional Amounts on presenting this
         Security for payment on the last day of such period of 30 days;

                  (c) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) in a Taxing Jurisdiction
         or, so long as the Senior Notes are listed on the Luxembourg Stock
         Exchange, in Luxembourg;

                  (d) to, or to a Person on behalf of, a Holder who would not be
         liable or subject to the withholding or deduction by making a
         declaration of nonresidence or similar claim for exemption to the
         relevant Taxing Jurisdiction; or

                  (e) to, or to a Person on behalf of, a Holder of a Registered
         Security that is not a Global Security issued pursuant to the request
         of any beneficial owner of an interest in the Security (an "Optional
         Definitive Security Request") following and during the continuance of
         an Event of Default if such Holder (or any predecessor Holder) was an
         owner requesting that such Registered Securities be so issued.

                  Such Additional Amounts will also not be payable where, had
the beneficial owner of the Security (or any interest therein) been the Holder
of the Security, such owner would not have been entitled to payment of
Additional Amounts by reason of any one or more of clauses (a) through (e)
above. If the Company or the Guarantor, as applicable, shall determine that
Additional Amounts will not be payable because of the immediately preceding
sentence, the Company or the Guarantor, as applicable, will inform such Holder
promptly after making such determination setting forth the reason(s) therefor.

                  "Relevant Date" means, in respect of any payment, whichever is
the later of (i) the date on which such payment first becomes due and (ii) if
the full amount payable has not been received in The City of New York by the
Book-Entry Depositary or the Trustee on or prior to such due date, the date on
which, the full amount having been so received, notice to that effect shall have
been given to the bearer hereof in accordance with the Indenture.

                  References to principal of, and premium or interest in respect
of, this Security or any payments pursuant to the Guarantee of this Security
shall be deemed to include any Additional Amounts which may be payable as set
forth in the Indenture or in this Security.

                  The Company shall furnish to the Trustee the official receipts
(or a certified copy of the official receipts) evidencing payment of the
Gross-Up Taxes. Copies of such receipts shall be made available to the Holder of
this Security upon request.

                  All notices regarding the Securities of this Series shall be
published in a leading English language daily newspaper of general circulation
in London. Furthermore, so long as the Securities of this series are listed on
the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange so
require, notices to Holders of Securities of this series will also be published
in a leading newspaper having general circulation in Luxembourg (which is
expected to be the Luxemburger Wort).

                          [Form of Reverse of Security]

                        YORKSHIRE POWER FINANCE 2 LIMITED
                    Reset Senior Notes Due February 15, 2020

                  This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of February 1, 2000 (herein called
the "Original Indenture"), among the Company, Yorkshire Power Group Limited, as
guarantor (the "Guarantor"), and The Bank of New York, as trustee, principal
paying agent, registrar and transfer agent (herein called the "Trustee", which
term includes any successor trustee under the Indenture), as supplemented by the
First Supplemental Indenture, dated as of February 16, 2000 (the "First
Supplemental Indenture"; together with the Original Indenture and any other
supplements thereto, the "Indenture"), among the Company, the Guarantor and the
Trustee to which Indenture reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee and the Holders of the Securities and of
the terms upon which the Securities are, and are to be, authenticated and
delivered. This Security is one of the series designated on the face hereof,
limited in aggregate principal amount to (pound)155,000,000; provided, however,
that upon a Conversion Event, such aggregate principal amount shall be limited
to $250,000,000.

                  Certain provisions with respect to the interest rate reset
procedures for the Securities after the Initial Reset Date set forth below are
contained in a Remarketing Agreement (the "Remarketing Agreement") between the
Company, the Guarantor and Warburg Dillon Read LLC, as Remarketing Agent (the
"Remarketing Agent").

                  In accordance with the procedures established in the
Remarketing Agreement and subject to Section 212 of the First Supplemental
Indenture, the interest rate in effect with respect to the Securities
immediately prior to the Initial Reset Date shall be reset on the Initial Reset
Date to equal the Interest Rate to Maturity which shall be effective from and
including the Initial Reset Date to but excluding the final maturity of the
Securities, unless the Company shall exercise the Floating Rate Option in
accordance with the provisions herein. If the Company shall have so exercised
the Floating Rate Option, then the Floating Period Interest Rate shall be reset
in accordance with the Remarketing Agreement on the Reset Date corresponding to
the Floating Rate Period Termination Date to equal the Interest Rate to
Maturity, which shall be effective from and including such Reset Date to but
excluding the final maturity of the Securities.

                  During the period from and including the Fixed Rate Reset Date
to but excluding the final maturity of the Securities, interest on the
Securities shall accrue on principal amount of the Securities at the Interest
Rate to Maturity and shall be payable semi-annually on each Interest Payment
Date, commencing with the first such Interest Payment Date following the Fixed
Rate Reset Date; provided, however, that, if any such Interest Payment Date is
not a Business Day, then payment of interest payable on such date will be made
on the next succeeding day which is a Business Day (and without any interest or
other payment in respect of any such delay). Interest on the Securities from the
Fixed Rate Reset Date shall be computed on the basis of a 360-day year
consisting of twelve 30-day months.

                                      A-8

<PAGE>

                  In accordance with procedures established in the Remarketing
Agreement and subject to Section 212 of the First Supplemental Indenture, if the
Company exercises the Floating Rate Option no later than the seventh Business
Day prior to the Floating Rate Spread Determination Date by providing notice to
the Trustee and Remarketing Agent, then the Securities shall bear interest at
the Floating Period Interest Rate for each Floating Rate Reset Period in the
Floating Rate Period.

                  During each Floating Rate Reset Period in the Floating Rate
Period, interest on the Securities shall accrue on the Floating Rate Purchase
Price at the Floating Period Interest Rate for such Floating Rate Reset Period
and shall be payable quarterly on each Interest Payment Date, commencing with
the first such Interest Payment Date following the Initial Reset Date. The
Interest Amount for such Floating Rate Reset Period shall be determined by (A)
applying the Floating Period Interest Rate for such Floating Rate Reset Period
to the Floating Rate Purchase Price and (B) multiplying that amount by the
actual number of days in such Floating Rate Reset Period divided by 365 (or, if
such Floating Rate Reset Period ends after February 28 in a leap year, 366)
expressed as a decimal and rounded upward if necessary to the nearest 1/16th of
1%.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Securities shall be automatically tendered, or deemed tendered,
by the Holders thereof to the Remarketing Agent for purchase on the Floating
Rate Period Termination Date. On the Reset Date corresponding to the Floating
Rate Period Termination Date, the interest rate on the Securities shall be reset
to equal the Interest Rate to Maturity in accordance with, and the Securities
shall be remarketed pursuant to, the Remarketing Agreement.

                  The purchase price for the Securities tendered pursuant to the
paragraph above shall equal 100% of the Floating Rate Purchase Price plus
accrued and unpaid interest, if any, thereon to but excluding the Floating Rate
Period Termination Date. If for any reason the Remarketing Agent does not
purchase all of the Securities on the Floating Rate Period Termination Date, the
Company shall redeem the Securities on the Floating Rate Period Termination Date
at a redemption price equal to 100% of the Floating Rate Purchase Price plus
accrued and unpaid interest, if any, thereon to but excluding the Floating Rate
Period Termination Date. If the Remarketing Agent elects to purchase the
Securities, such obligation of the Remarketing Agent is subject to the
conditions set forth in the Remarketing Agreement.

                  In the event that the Callholder (i) has not given notice on
or before January 10, 2005 of its intention to exercise the call option under
the Call Option Agreement or (ii) fails to pay on or before the Business Day
next preceding the Early Redemption Date the call price required under the Call
Option Agreement, the Company shall redeem on February 15, 2005 (such date,
unless it is not a Business Day, in which case the next succeeding day that is a
Business day, the "Early Redemption Date"), in whole but not in part, the
Securities at a redemption price equal to 100% of the aggregate principal amount
of the Securities plus accrued and unpaid interest thereon to but excluding the
Early Redemption Date, upon written notice by 5:00 p.m. London time on the
Business Day next preceding Early Redemption Date from the Book-Entry
Depository, as holder of the Securities.

                                      A-9

<PAGE>

                  Any such written notice given by the Book-Entry Depository, as
holder of the Securities, shall be irrevocable; provided, however, that if prior
to the Early Redemption Date an Event of Default shall have occurred and be
continuing, such holder, at its option, may elect by written notice to the
Company, to withdraw such instruction and instead to declare the Securities to
be due and payable pursuant to Section 502 of the Original Indenture.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Company shall be required to redeem the Securities, in whole
but not in part, on any Reset Date following the Initial Reset Date at a
redemption price equal to the Floating Rate Purchase Price plus accrued and
unpaid interest, if any, thereon to but excluding such Reset Date in the event
that (i) the Remarketing Agent for any reason does not notify the Company of the
Floating Period Interest Rate for the Floating Rate Reset Period beginning on
such Reset Date by 4:00 p.m. (London time) on such Reset Date or of the Interest
Rate to Maturity by 4:00 p.m., (London time) on the Fixed Rate Determination
Date, as applicable, (ii) prior to any such Reset Date, the Remarketing Agent
resigns and no successor has been appointed on or before such Reset Date or
Determination date, as applicable, (iii) the Remarketing Agent elects to
terminate the Remarketing Agreement in accordance with its terms, (iv) the
Remarketing Agent for any reason does not elect (by notice to the Company and
the Trustee not later than the Fixed Rate Determination Date) to purchase the
Securities for remarketing on the Floating Rate Period Termination Date, (v) the
Remarketing Agent for any reason does not deliver the purchase price of the
Securities to or through DTC on or before the Floating Rate Period Termination
Date as provided in the Remarketing Agreement or (vi) the Company for any reason
fails to redeem the Securities following the Company's election to effect such
redemption as set forth in paragraph (c) of this Section 212.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Company shall notify the Callholder, the Remarketing Agent and
the Trustee, not later than the Business Day immediately preceding the Floating
Rate Period Termination Date, if the Company irrevocably elects to exercise its
right to redeem the Senior Notes, in whole but not in part, from the Remarketing
Agent on the Floating Rate Period Termination Date. If the Company elects to
redeem the Securities, the Company shall redeem the Securities in whole at a
redemption price equal to the Floating Rate Purchase Price plus accrued and
unpaid interest, if any, thereon to but excluding the Floating Rate Period
Termination Date.

                  The tender and settlement procedures set forth above,
including provisions for payment by purchasers of the Securities to any
remarketing agent or for payment of the Securities, may be modified to the
extent required by DTC or to the extent required to facilitate the tender and
remarketing of the Securities at the time of the remarketing. In addition, the
Remarketing Agent may, without the consent of holders of the Securities, modify
the tender and settlement procedures specified above in order to facilitate the
tender and settlement process.

                  Unless the Company defaults in payment of the redemption
price, from and after a redemption date, the Securities of this series or
portions thereof called for redemption will cease to bear interest, and the
Holders thereof will have no right in respect of such Securities of this series
except the right to receive the redemption price thereof.

<PAGE>

                  The Indenture contains provisions for defeasance of (a) the
entire indebtedness of the Securities and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

                  If an Event of Default with respect to the Securities shall
occur and be continuing, the principal of the Securities may be declared due and
payable in the manner and with the effect provided in the Indenture. At any time
after such declaration of acceleration with respect to the Securities has been
made, but before a judgment or decree for payment of money has been obtained by
the Trustee as provided in the Indenture, if all Events of Default with respect
to the Securities have been cured or waived (other than the non-payment of
principal of the Securities which has become due solely by reason of such
declaration of acceleration) then such declaration of acceleration and its
consequences shall be automatically annulled and rescinded.

                  This Security is subject to redemption in whole but not in
part upon not less than 30 nor more than 60 days' notice given as provided in
the Indenture, at a price equal to the outstanding principal amount thereof,
together with Additional Amounts, if any, and accrued interest, if any, to the
Redemption Date if, (a) the Company or the Guarantor satisfies the Trustee prior
to the giving of such notice that it has or will become obligated to pay
Additional Amounts as a result of either (i) any change in, or amendment to, the
laws or regulations of a Taxing Jurisdiction, or any change in the application
or interpretation of such laws or regulations, which change or amendment becomes
effective on or after February 16, 2000 (or, in the case of any jurisdiction
other than a Taxing Jurisdiction, any such change or amendment that becomes
effective on or after the date on which the Company or the Guarantor, as the
case may be, is merged into, or conveyed or transferred or leased its properties
and assets substantially as an entirety to, any Person that is organized under
the laws of, or is managed or controlled or has a place of business in, such
jurisdiction) or (ii) the issuance of Definitive Registered Securities pursuant
to any of clauses (a), (b) or (d) of the third following paragraph and (b) such
obligation cannot be avoided by the Company or the Guarantor taking reasonable
measures available to it, subject, as provided in the Indenture, to the delivery
by the Company or the Guarantor of an Officers' Certificate stating that such
obligation to pay Additional Amounts cannot be avoided by the Company or the
Guarantor taking reasonable measures available to it.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the Indenture or any
supplemental indenture or the rights and obligations of the Company and the
rights of the Holders of the Securities of all series to be affected under the
Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in aggregate principal amount of the Securities at the
time Outstanding of all series to be affected (voting as a class). 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 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.

                  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 in respect of this Security at the times, place
and rate, and in the coin or currency, herein prescribed.

                  This Security shall be exchangeable, in whole or, in the case
of clause (d) below, in part as provided in the Indenture, for Definitive
Registered Securities registered in the names of Persons other than the
Book-Entry Depositary with respect to such series or its nominee only as
provided in this paragraph. This Security shall be so exchangeable if (a) DTC
notifies the Company and the Book-Entry Depositary that it is unwilling or
unable to continue to hold the Book-Entry Interests or at any time ceases to be
a "clearing agency" registered as such under the Exchange Act and in either
case, a successor is not appointed by the Company within 120 days, (b) the
Book-Entry Depositary for the Securities of this series notifies the Company
that it is unwilling or unable to continue as Book-Entry Depositary with respect
to this Security and no successor is appointed within 120 days, (c) the Company
executes and delivers to the Trustee an Officers' Certificate providing that
this Security shall be so exchangeable, (d) the Company receives an Optional
Definitive Securities Request or (e) while this Security is subject to the
transfer restrictions set forth in the Restricted Securities Legend hereon, on
or after the Initial Reset Date the Book-Entry Interests cease to be eligible
for DTC services because this Security is neither (i) rated in one of the top
four categories by a nationally recognized statistical rating organization nor
(ii) included within a self-regulatory organization system approved by the
Commission for the reporting of quotations and trade information of securities
eligible for trade pursuant to Rule 144A, such as the PORTAL system. Securities
so issued in exchange for this Security shall be of the same series, having the
same interest rate, if any, and maturity and having the same terms as this
Security, in authorized denominations and in the aggregate having the same
principal amount as this security and registered in such names as the Book-Entry
Depositary for this Security shall direct.

                  The bearer of this Security shall be treated as the owner of
it for all purposes, subject to the terms of the Indenture. 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 and of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

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

                  When a successor assumes all the obligations of its
predecessor under the Securities of this series and the Indenture in accordance
with the terms of the Indenture, the predecessor will be released from those
obligations.

                  The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Securities of this series and
may otherwise deal with the Company, the Guarantor or their respective
Affiliates as if it were not the Trustee.

<PAGE>

                  No stockholder, director, officer, employee, incorporator or
Affiliate of the Company or the Guarantor shall have any liability for any
obligation of the Company or the Guarantor under the Securities of this series
or the Indenture or for any claim based on, in respect of or by reason of, such
obligations or their creation. Each Holder of the Securities of this series by
accepting Securities of this series waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the
Securities of this series.

                  This Security shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on this Security.

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company will cause CUSIP numbers
to be printed on the Securities of this series as a convenience to the Holders
of the Securities of this series. No representation is made as to the accuracy
of such numbers as printed on the Securities of this series and reliance may be
placed only on the other identification numbers printed hereon.

                  This Security shall be governed by and construed in accordance
with the laws of the State of New York.

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

                                    GUARANTEE

                  FOR VALUE RECEIVED, YORKSHIRE POWER GROUP LIMITED, a private
limited company duly incorporated and existing under the laws of England and
Wales (the "Guarantor", which term includes any successor Person under the
Indenture referred to in the Security on which this notation is endorsed),
hereby fully and unconditionally guarantees to the Holder of the accompanying
Security issued by Yorkshire Power Finance 2 Limited (the "Company"), pursuant
to the terms of the Guarantee contained in Article Fourteen of the Indenture,
the due and punctual payment of the principal of, and premium, if any, and
interest in respect of this Security (and any Additional Amounts payable in
respect thereof), when and as the same shall become due and payable, whether at
Stated Maturity, by declaration of acceleration, call for redemption or
otherwise, in accordance with the terms of this Security and the Indenture. In
case of the failure of the Company punctually to pay any such principal,
premium, if any, or interest, the Guarantor hereby agrees to cause such payment
to be made punctually when and as the same shall become due and payable as if
such payment were made by the Company.

                  The obligations of the Guarantor to the Holders of the
Securities and to the Trustee pursuant to the Guarantee and the Indenture are
expressly set forth in Article Fourteen of the Indenture, and reference is
hereby made to such Article and Indenture for the precise terms of the
Guarantee.

ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK.

                  The Guarantee shall not be valid or obligatory for any purpose
until the certificate of authentication on the Security upon which this notation
of the Guarantee is endorsed shall have been executed by the Trustee or the
authenticating agent under the Indenture by the manual signature of one of its
authorized officers.

                  YORKSHIRE POWER FINANCE 2 LIMITED, a limited liability company
incorporated under the laws of the Cayman Islands (herein called the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to [name of registered
owner], or its registered assigns, the principal sum of ONE HUNDRED FIFTY FIVE
MILLION POUNDS STERLING on February 15, 2020, and to pay interest thereon at the
rate or rates per annum described herein from February 16, 2000, or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semi-annually on February 15 and August 15 in each year,
commencing August 15, 2000, to the Initial Reset Date and thereafter subject to
the terms and conditions set forth herein, at the interest rate or rates
determined by the Remarketing Agent in accordance with the procedures set forth
on the reverse hereof, until the principal hereof is paid or made available for
payment. The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the fifteenth day (whether or not a Business Day)
immediately preceding such Interest Payment Date. Any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered on such Regular Record Date and may be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Securities of this series not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in said Indenture.
-----------------------------------

      *Reference is made to (i) Schedule A attached hereto with respect to
      decreases and increases in the aggregate principal amount of Securities
      evidenced by this certificate and (ii) the other provisions of this
      Security providing for the conversion to a US Dollar denominated Security.

                                      B-1
<PAGE>

                  The per annum interest rate on the Securities for each
Interest Accrual Period through the Initial Reset Date will be reset
semi-annually based on procedures set forth below and established in the
Indenture; provided, however, that upon the occurrence of a Conversion Event,
this Security will convert to a US Dollar denominated Security as provided in
the Indenture.

                  The rate of interest payable from time to time through the
Initial Reset Date in respect of this Security for any Interest Accrual Period
(the "Rate of Interest") will be determined on the basis of the following
provisions:

                  (i) on the first day of such Interest Accrual Period (the
         "Interest Determination Date"), the Agent Bank will determine the
         Screen Rate for six-month Sterling deposits at or about 11:00 a.m.
         (London time) on the Interest Determination Date. If such Screen Rate
         is unavailable, the Agent Bank will request the principal London office
         of each of the Reference Banks to provide the Agent Bank with its
         offered quotation to leading banks for Sterling deposits in the London
         interbank market for such Interest Accrual Period at or about 11:00
         a.m. (London time) on the Interest Determination Date. The Rate of
         Interest for such Interest Accrual Period shall be such Screen Rate
         plus 0.805% per annum (the "Margin") or, if such Screen Rate is
         unavailable, the arithmetic average (rounded upwards if necessary to
         the nearest 1/16th of 1%) of the offered quotations provided by the
         Reference Banks (excluding the highest and lowest (or, in either case,
         if more than one, then only one of them) of such quotations) plus the
         Margin;

                  (ii) if on the Interest Determination Date such Screen Rate is
         unavailable and only four of the Reference Banks provide offered
         quotations, the Rate of Interest for such Interest Accrual Period shall
         be determined in accordance with the provisions of paragraph (i) above
         on the basis of the offered quotations of those Reference Banks
         providing the offered quotations (excluding the highest and lowest of
         such quotations as provided in paragraph (i) above);

                  (iii) if on the Interest Determination Date such Screen Rate
         is unavailable and only two or three of the Reference Banks provide
         offered quotations, the Rate of Interest for such Interest Accrual
         Period shall be determined in accordance with the provisions of
         paragraph (i) above on the basis of the offered quotations of those
         Reference Banks providing the offered quotations (but without excluding
         the highest and lowest of such quotations as provided in paragraph (i)
         above); and

                  (iv) if on the Interest Determination Date such Screen Rate is
         unavailable and only one or none of the Reference Banks provides an
         offered quotation, then the Rate of Interest for such Interest Accrual
         Period shall be (a) the Rate of Interest in effect for that Interest
         Accrual Period to which paragraph (i), (ii) or (iii) above shall have
         applied which last preceded such Interest Accrual Period or (b) if
         determinable and if higher, the Reserve Interest Rate. The "Reserve
         Interest Rate" (as defined below) shall be the rate per annum which the
         Agent Bank determines to be either (A) the arithmetic average (rounded
         upward if necessary to the nearest 1/16th of 1%) of the Sterling
         lending rates for loans in an amount approximately equal to the
         principal amount of the Securities which London banks selected by the

                                      B-2

<PAGE>

         Agent Bank are quoting, at or about 11:00 a.m. (London time) on the
         Interest Determination Date, for such Interest Accrual Period, to the
         Reference Banks or those of them (being at least two in number) to
         which the quotations are, in the opinion of the Agent Bank, being so
         made plus the Margin or (B) if the Agent Bank cannot determine the
         arithmetic average, the lowest Sterling lending rate which four London
         banks selected by the Agent Bank are quoting, on the Interest
         Determination Date, for such Interest Accrual Period, to leading
         European banks plus the Margin.

                  The Interest Amount shall be determined by (I) applying the
Rate of Interest for such Interest Accrual Period to the principal amount of the
Securities and (ii) multiplying that amount by the actual number of days in such
Interest Accrual Period divided by 365 (or if such Interest Accrual Period ends
after February 28 in a leap year, 366) expressed as a decimal and rounded upward
if necessary to the nearest 1/16th of 1%.

                  Reference is hereby made to the further provisions of this
Security set forth on the reverse hereof relating to the interest reset and
remarketing mechanics of this Security after the Initial Reset Date.

                  All payments in respect of this Security and all payments made
pursuant to the Guarantee of this Security shall be made in immediately
available funds at or through the office or agency of the Company maintained for
that purpose in the Borough of Manhattan, The City of New York, and for so long
as this Security shall be listed on the Luxembourg Stock Exchange, in
Luxembourg, in such coin or currency of the United Kingdom or the United States
of America, as the case may be, as at the time of payment is legal tender for
the payment of public and private debt. The Trustee shall make
Sterling-denominated payments on the Senior Notes through a London-based account
of the Trustee.

                  All payments of principal of, and premium, if any, and
interest in respect of this Security and all payments made pursuant to the
Guarantee of this Security shall be made free and clear of, and without
withholding or deduction for or on account of any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed, levied,
collected, withheld or assessed by or within a Taxing Jurisdiction or by or
within any political subdivision thereof or any authority therein or thereof
having power to tax ("Gross-Up Taxes"), unless such withholding or deduction is
required by law. In the event of any such withholding or deduction, the Company
or the Guarantor, as the case may be, shall pay to the Holder such additional
amounts in respect of such withholding or reduction as are necessary so that the
Holder receives the amount that would have been due in the absence of such
withholding or deduction ("Additional Amounts"), except that no such Additional
Amounts shall be payable:

                  (a) to, or to a Person on behalf of, a Holder who is liable
         for such Gross-Up Taxes in respect of this Security or the Guarantee of
         this Security by reason of such Holder or beneficial owner having some
         connection with the relevant Taxing Jurisdiction (including being a
         citizen or resident or national of, or carrying on a business or
         maintaining a permanent establishment in, or being physically present
         in, such Taxing Jurisdiction) other than the mere holding of this
         Security or the receipt of principal of, and premium, if any, and
         interest in respect thereon or in respect of the Guarantee of this
         Security;

                                      B-3

<PAGE>

                  (b) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) for payment more than 30
         days after the Relevant Date except to the extent that the Holder would
         have been entitled to such Additional Amounts on presenting this
         Security for payment on the last day of such period of 30 days;

                  (c) to, or to a Person on behalf of, a Holder who presents
         this Security (where presentation is required) in a Taxing Jurisdiction
         or, so long as the Senior Notes are listed on the Luxembourg Stock
         Exchange, in Luxembourg;

                  (d) to, or to a Person on behalf of, a Holder who would not be
         liable or subject to the withholding or deduction by making a
         declaration of nonresidence or similar claim for exemption to the
         relevant Taxing Jurisdiction; or

                  (e) to, or to a Person on behalf of, a Holder of a Registered
         Security that is not a Global Security issued pursuant to the request
         of any beneficial owner of an interest in the Security (an "Optional
         Definitive Security Request") following and during the continuance of
         an Event of Default if such Holder (or any predecessor Holder) was an
         owner requesting that such Registered Securities be so issued.

                  Such Additional Amounts will also not be payable where, had
the beneficial owner of the Security (or any interest therein) been the Holder
of the Security, such owner would not have been entitled to payment of
Additional Amounts by reason of any one or more of clauses (a) through (e)
above. If the Company or the Guarantor, as applicable, shall determine that
Additional Amounts will not be payable because of the immediately preceding
sentence, the Company or the Guarantor, as applicable, will inform such Holder
promptly after making such determination setting forth the reason(s) therefor.

                  "Relevant Date" means, in respect of any payment, whichever is
the later of (i) the date on which such payment first becomes due and (ii) if
the full amount payable has not been received in The City of New York by the
Book-Entry Depositary or the Trustee on or prior to such due date, the date on
which, the full amount having been so received, notice to that effect shall have
been given to the bearer hereof in accordance with the Indenture.

                  References to principal of, and premium or interest in respect
of, this Security or any payments pursuant to the Guarantee of this Security
shall be deemed to include any Additional Amounts which may be payable as set
forth in the Indenture or in this Security.

                  The Company shall furnish to the Trustee the official receipts
(or a certified copy of the official receipts) evidencing payment of the
Gross-Up Taxes. Copies of such receipts shall be made available to the Holder of
this Security upon request.

                  All notices regarding the Securities of this Series shall be
published in a leading English language daily newspaper of general circulation
in London. Furthermore, so long as the Securities of this series are listed on
the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange so
require, notices to Holders of Securities of this series will also be published
in a leading newspaper having general circulation in Luxembourg (which is
expected to be the Luxemburger Wort).

this Security shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.

                          [Form of Reverse of Security]

                        YORKSHIRE POWER FINANCE 2 LIMITED
                    Reset Senior Notes Due February 15, 2020

                  This Security is one of a duly authorized issue of securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of February 1, 2000 (herein called
the "Original Indenture"), among the Company, Yorkshire Power Group Limited, as
guarantor (the "Guarantor"), and The Bank of New York, as trustee, principal
paying agent, registrar and transfer agent (herein called the "Trustee", which
term includes any successor trustee under the Indenture), as supplemented by the
First Supplemental Indenture, dated as of February 16, 2000 (the "First
Supplemental Indenture"; together with the Original Indenture and any other
supplements thereto, the "Indenture"), among the Company, the Guarantor and the
Trustee to which Indenture reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Guarantor, the Trustee and the Holders of the Securities and of
the terms upon which the Securities are, and are to be, authenticated and
delivered. This Security is one of the series designated on the face hereof,
limited in aggregate principal amount to (pound)155,000,000; provided, however,
that upon a Conversion Event, such aggregate principal amount shall be limited
to $250,000,000.

                  Certain provisions with respect to the interest rate reset
procedures for the Securities after the Initial Reset Date set forth below are
contained in a Remarketing Agreement (the "Remarketing Agreement") between the
Company, the Guarantor and UBS AG, London Branch or any affiliate thereof, as
Remarketing Agent (the "Remarketing Agent").

                  In accordance with the procedures established in the
Remarketing Agreement and subject to Section 212 of the First Supplemental
Indenture, the interest rate in effect with respect to the Securities
immediately prior to the Initial Reset Date shall be reset on the Initial Reset
Date to equal the Interest Rate to Maturity which shall be effective from and
including the Initial Reset Date to but excluding the final maturity of the
Securities, unless the Company shall exercise the Floating Rate Option in
accordance with the provisions herein. If the Company shall have so exercised
the Floating Rate Option, then the Floating Period Interest Rate shall be reset
in accordance with the Remarketing Agreement on the Reset Date corresponding to
the Floating Rate Period Termination Date to equal the Interest Rate to
Maturity, which shall be effective from and including such Reset Date to but
excluding the final maturity of the Securities.

                  During the period from and including the Fixed Rate Reset Date
to but excluding the final maturity of the Securities, interest on the
Securities shall accrue on principal amount of the Securities at the Interest
Rate to Maturity and shall be payable semi-annually on each Interest Payment
Date, commencing with the first such interest Payment Date following the Fixed
Rate Reset Date; provided, however, that, if any such Interest Payment Date is
not a Business Day, then payment of interest payable on such date will be made
on the next succeeding day which is a Business Day (and without any interest or
other payment in respect of any such delay). Interest on the Securities from the
Fixed Rate Reset Date shall be computed on the basis of a 360-day year
consisting of twelve 30-day months.

                                      B-7

<PAGE>

                  In accordance with procedures established in the Remarketing
Agreement and subject to Section 212 of the First Supplemental Indenture, if the
Company exercises the Floating Rate Option no later than the seventh Business
Day prior to the Floating Rate Spread determination Date by providing notice to
the Trustee and Remarketing Agent, then the Securities shall bear interest at
the Floating Period Interest Rate for each Floating Rate Reset Period in the
Floating Rate Period.

                  During each Floating Rate Reset Period in the Floating Rate
Period, interest on the Securities shall accrue on the Floating Rate Purchase
Price at the Floating Period Interest Rate for such Floating Rate Reset Period
and shall be payable quarterly on each Interest Payment Date, commencing with
the first such Interest Payment Date following the Initial Reset Date. The
Interest Amount for such Floating Rate Reset Period shall be determined by (A)
applying the Floating Period Interest Rate for such Floating Rate Reset Period
to the Floating Rate Purchase Price and (B) multiplying that amount by the
actual number of days in such Floating Rate Reset Period divided by 365 (or, if
such Floating Rate Reset Period ends after February 28 in a leap year, 366)
expressed as a decimal and rounded upward if necessary to the nearest 1/16th of
1%.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Securities shall be automatically tendered, or deemed tendered,
by the Holders thereof to the Remarketing Agent for purchase on the Floating
Rate Period Termination Date. On the Reset Date corresponding to the Floating
Rate Period Termination Date, the interest rate on the Securities shall be reset
to equal the Interest Rate to Maturity in accordance with, and the Securities
shall be remarketed pursuant to, the Remarketing Agreement.

                  The purchase price for the Securities tendered pursuant to the
paragraph above shall equal 100% of the Floating Rate Purchase Price plus
accrued and unpaid interest, if any, thereon to but excluding the Floating Rate
Period Termination Date. If for any reason the Remarketing Agent does not
purchase all of the Securities on the Floating Rate Period Termination Date, the
Company shall be required to redeem the Securities at a redemption price equal
to 100% of the Floating Rate Purchase Price plus accrued and unpaid interest, if
any, thereon to but excluding the Floating Rate Period Termination Date. If the
Remarketing Agent elects to purchase the Securities, such obligation of the
Remarketing Agent is subject to the conditions set forth in the Remarketing
Agreement.

                  In the event that the Callholder (i) has not given notice on
or before January 10, 2005 of its intention to exercise the call option under
the Call Option Agreement or (ii) fails to pay on or before the Business Day
next preceding the Early Redemption Date the call price required under the Call
Option Agreement, the Company shall redeem on February 15, 2005 (such date,
unless it is not a Business Day, in which case the next succeeding day that is a
Business day, the "Early Redemption Date"), in whole but not in part, the
Securities at a redemption price equal to 100% of the aggregate principal amount
of the Securities plus accrued and unpaid interest thereon to but excluding the
Early Redemption Date, upon written notice by 5:00 p.m. London time on the
Business Day next preceding Early Redemption Date from the Book-Entry
Depository, as holder of the Securities.

                                      B-8

<PAGE>

                  Any such written notice given by the Book-Entry Depository, as
holder of the Securities, shall be irrevocable; provided, however, that if prior
to the Early Redemption Date an Event of Default shall have occurred and be
continuing, such holder, at its option, may elect by written notice to the
Company, to withdraw such instruction and instead to declare the Securities to
be due and payable pursuant to Section 502 of the Original Indenture.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Company shall be required to redeem the Securities, in whole
but not in part, on any Reset Date following the Initial Reset Date at a
redemption price equal to the Floating Rate Purchase Price plus accrued and
unpaid interest, if any, thereon to but excluding such Reset Date in the event
that (i) the Remarketing Agent for any reason does not notify the Company of the
Floating Period Interest Rate for the Floating Rate Reset Period beginning on
such Reset Date by 4:00 p.m. (London time) on such Reset Date or of the Interest
Rate to Maturity by 4:00 p.m., (London time) on the Fixed Rate Determination
Date, as applicable, (ii) prior to any such Reset Date, the Remarketing Agent
resigns and no successor has been appointed on or before such Reset Date or
Determination date, as applicable, (iii) the Remarketing Agent elects to
terminate the Remarketing Agreement in accordance with its terms, (iv) the
Remarketing Agent for any reason does not elect (by notice to the Company and
the Trustee not later than the Fixed Rate Determination Date) to purchase the
Securities for remarketing on the Floating Rate Period Termination Date, (v) the
Remarketing Agent for any reason does not deliver the purchase price of the
Securities to or through DTC on or before the Floating Rate. Period Termination
Date as provided in the Remarketing Agreement or (vi) the Company for any reason
fails to redeem the Securities following the Company's election to effect such
redemption as set forth in paragraph (c) of this Section 212.

                  If the Callholder shall have purchased the Securities pursuant
to the Call Option Agreement and the Company shall have elected the Floating
Rate Option, the Company shall notify the Callholder, the Remarketing Agent and
the Trustee, not later than the Business Day immediately preceding the Floating
Rate Period Termination Date, if the Company irrevocably elects to exercise its
right to redeem the Senior Notes, in whole but not in part, from the Remarketing
Agent on the Floating Rate Period Termination Date. If the Company elects to
redeem the Securities, the Company shall redeem the Securities on the Floating
Rate Period Termination Date in whole at a redemption price equal to the
Floating Rate Purchase Price plus accrued and unpaid interest, if any, thereon
to but excluding the Floating Rate Period Termination Date.

                  The tender and settlement procedures set forth above,
including provisions for payment by purchasers of the Securities to any
remarketing agent or for payment of the Securities, may be modified to the
extent required by DTC or to the extent required to facilitate the tender and
remarketing of the Securities at the time of the remarketing. In addition, the
Remarketing Agent may, without the consent of holders of the Securities, modify
the tender and settlement procedures specified above in order to facilitate the
tender and settlement process.

                  Unless the Company defaults in payment of the redemption
price, from and after a redemption date, the Securities of this series or

                                      B-9

<PAGE>

portions thereof called for redemption will cease to bear interest, and the
Holders thereof will have no right in respect of such Securities of this series
except the right to receive the redemption price thereof.

                  The Indenture contains provisions for defeasance of (a) the
entire indebtedness of the Securities and (b) certain restrictive covenants upon
compliance by the Company with certain conditions set forth therein.

                  If an Event of Default with respect to the Securities shall
occur and be continuing, the principal of the Securities may be declared due and
payable in the manner and with the effect provided in the Indenture. At any time
after such declaration of acceleration with respect to the Securities has been
made, but before a judgment or decree for payment of money has been obtained by
the Trustee as provided in the Indenture, if all Events of Default with respect
to the securities have been cured or waived (other than the non-payment of
principal of the Securities which has become due solely by reason of such
declaration of acceleration) then such declaration of acceleration and its
consequences shall be automatically annulled and rescinded.

                  This Security is subject to redemption in whole but not in
part upon not less than 30 nor more than 60 days' notice given as provided in
the Indenture, at a price equal to the outstanding principal amount thereof,
together with Additional Amounts, if any, and accrued interest, if any, to the
Redemption Date if (a) the Company or the Guarantor satisfies the Trustee prior
to the giving of such notice that it has or will become obligated to pay
Additional Amounts as a result of either (i) any change in, or amendment to, the
laws or regulations of a Taxing Jurisdiction, or any change in the application
or interpretation of such laws or regulations, which change or amendment becomes
effective on or after February 16, 2000 (or, in the case of any jurisdiction
other than a Taxing Jurisdiction, any such change or amendment that becomes
effective on or after the date on which the Company or the Guarantor, as the
case may be, is merged into, or conveyed or transferred or leased its properties
and assets substantially as an entirety to, any Person that is organized under
the laws of, or is managed or controlled or has a place of business in, such
jurisdiction) or (ii) the issuance of Definitive Registered Securities as a
result of: (A) DTC having notified the Company and the Book-Entry Depositary
that it was unwilling or unable to continue to hold the Book-Entry Interest or
at any time ceasing to be "a clearing agency" registered as such under the
Securities Exchange Act of 1934 and, in either case, a successor is not being
appointed by the Company within 120 days; (B) the Book-Entry Depositary for the
Securities of this series having notified the Company that it was unwilling or
unable to continue as Book-Entry Depositary with respect to a Global security of
this series and no successor Book-Entry Depositary having been appointed by the
Company within 120 days or (C) an Event of Default with respect to the
Securities of this series having occurred and being continuing and a Holder, in
such circumstance, having requested in writing that a Global Bearer Security of
this series be exchanged for one or more Definitive Registered Securities and
(b) such obligation cannot be avoided by the Company or the Guarantor taking
reasonable measures available to it, subject, as provided in the indenture, to
the delivery by the Company or the Guarantor of an Officers' Certificate stating
that such obligation to pay Additional Amounts cannot be avoided by the Company
or the Guarantor taking reasonable measures available to it.

                  The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the Indenture or any
supplemental indenture or the rights and obligations of the Company and the
rights of the Holders of the Securities of all series to be affected under the

                                      B-10

<PAGE>

Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in aggregate principal amount of the Securities at the
time Outstanding of all series to be affected (voting as a class). 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 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.

                  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 in respect of 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, Securities of this series are exchangeable for a
like aggregate principal amount of Securities of this series and of like tenor
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 to
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 Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

                  When a successor assumes all the obligations of its
predecessor under the Securities of this series and the Indenture in accordance
with the terms of the Indenture, the predecessor will be released from those
obligations.

                  The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Securities of this series and
may otherwise deal with the Company, the Guarantor or their respective
Affiliates as if it were not the Trustee.

                  No stockholder, director, officer, employee, incorporator or
Affiliate of the Company or the Guarantor shall have any liability for any
obligation of the Company or the Guarantor under the Securities of this series

obligations of their creation. Each Holder of the Securities of this series by
accepting Securities of this series waives and releases all such liability. The
waiver and release are part of the consideration for the issuance of the
Securities of this series.
