Act and any other requirements set forth in this Indenture.

covenant or condition and the definitions herein relating thereto;

          SECTION 1.3. Form of Documents Delivered to Trustee

certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be
based, insofar as it relates to factual matters, upon a certificate or opinion of, or

          SECTION 1.4. Acts of Holders

          (a) Any request, demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given or taken by Holders of any or all series of Securities may
be embodied in and evidenced by one or more instruments of substantially similar tenor signed by
such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or instruments are
delivered to the Trustee, in person or by first class mail, postage prepaid, 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 conclusive in
favor of the Trustee and the Company, if made in the manner provided in this Section 1.4.

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

          (c) The ownership, principal amount and serial numbers of Securities held by any Person, and
the date of holding the same, shall be proved by the Security Register referred to in Section 2.9.

          The Company shall notify the Trustee, in writing, when it or any of its affiliates repurchases
or otherwise acquires Securities, of the aggregate principal amount of such Securities so
repurchased or otherwise acquired. The Trustee may require an Officers’ Certificate listing
Securities owned by the Company, a Subsidiary of the Company or an affiliate of the Company.

9

 

          (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) If the Company shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to
a Board Resolution, fix in advance a record date for the determination of Holders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other Act, but the
Company shall have no obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that purpose the
Outstanding Securities shall be computed as of such record date; provided that no such
authorization, agreement or consent by the Holders on such record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

          SECTION 1.5. 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 shall be sufficient for every purpose
hereunder if in writing and mailed first-class, postage pre-paid to the Trustee at its
Corporate Trust Office or received by the Trustee via facsimile, 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 or with it addressed to the Company at the address of its
principal office specified in the first paragraph of this instrument or at any other
address preciously furnished in writing to the Trustee by the Company or via facsimile.

          SECTION 1.6. Notice to Holders; Waiver

          Where this Indenture provides for notice to Holders of any event, such notice to the Holders
thereof shall be sufficiently given (unless otherwise herein expressly provided) (a) with respect
to Global Securities, if in writing and delivered or

10

 

mailed and received, first-class postage prepaid, to the Depositary at the address previously
furnished in writing by the Depositary to the Trustee and the Company and (b) if Outstanding
Definitive Securities are affected, if in writing and mailed, first-class postage prepaid, to each
such Holder affected by such event, at his address as it appears in the Security Register referred
to in Section 2.9, within the time 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.

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

          Where this Indenture provides for notice in any manner, such notice may be waived in writing
by the Person entitled to receive such notice, either before or after the event and such waiver
shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

          SECTION 1.7. Conflict with Trust Indenture Act

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

          SECTION 1.8. Effect of Headings and Table of Contents

          The Article and section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

          SECTION 1.9. Successors and Assigns

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

          SECTION 1.10. Separability Clause

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

11

 

          SECTION 1.11. Benefits of Indenture

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

          SECTION 1.12. Governing Law

          This Indenture (including, without limitation, the rights, duties, privileges, powers and
immunities of the Trustee) and the Securities shall be governed by and construed in accordance with
the laws of the State of New York except that matters relating to the authorization and execution
by the Company of this Indenture and the Securities and any other matters required to be governed
by the laws of the United Kingdom shall be governed by the laws of the United Kingdom.

          SECTION 1.13. Counterparts

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

          SECTION 1.14. Submission to Jurisdiction by the Company

          The Company agrees that any legal suit, action or preceding arising out of or relating to the
Indenture or the Securities may be instituted in any state or federal court in the Borough of
Manhattan, The City of New York, United States of America and to the extent it may effectively do
so, the Company hereby waives, and agrees not to assert, by way of motion, as a defense or
otherwise, in any such suit, action or proceeding any claim which it may now or hereafter have that
it is not personally subject to the jurisdiction of the above-named courts, that the suit, action
or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding
is improper or that this Indenture or the subject matter hereof may not be enforced by such court,
and irrevocably submits to the jurisdiction of any such court in any such suit, action or
proceeding. The Company hereby designates CT Corporation System as the Company’s authorized agent
to accept and acknowledge on its behalf service of any and all process which may be served in any
such suit, action or proceeding in any such court and agrees that service of process upon said
agent at its office at 111 Eighth Avenue, 13th Floor, New York, NY 10011 (or at such

written notice to the Company and the Trustee), and written notice of said service to the Company,
mailed or delivered to it, at 1 Grosvenor Place, London SW1X TJH, England, Attention : Treasurer,
shall be deemed in every respect effective service of process upon the Company in any such suit,
action or proceeding and shall be taken and held to be valid personal service upon the Company,
whether or not the Company shall then be doing, or at any time shall have done, business within the
State of New York, and that any such service of process shall be of the same force and validity as
if service were made upon it according to the laws governing the

12

 

validity and requirements of such service in such State, and waives all claim of error by
reason of any such service. Said designation and appointment shall be irrevocable until the
Indenture shall have been satisfied and discharged in accordance with Article Ten.

          Notwithstanding the foregoing, any actions arising out of or relating to the Securities or
this Indenture may be instituted by any party hereto and, subject to the limitations set forth in
Article Five of this Indenture, by the Holder of any Security in any competent court in England and
Wales.

          Nothing in this Section shall affect the right of the Trustee or any Holder of any Security to
serve process in any manner permitted by applicable law or limit the right of the Trustee or any
Holder of any Security to bring proceedings against the Company in the courts of any other
jurisdiction or jurisdictions.

          SECTION 1.15. Judgment Currency

          The Company agrees, to the fullest extent that it may effectively do so under applicable law,

3.1(b)) on the Securities of any series (the “Required Currency”) into a currency in which a
judgment will be rendered the “Judgment Currency”), the rate of exchange used shall be the rate at

exchange used shall be the rate at which at The Bank of New York in New York City the Trustee could
purchase the Required Currency with the Judgment Currency on the New York Banking Day preceding the
day on which a final unappealable judgment is entered and (b) its obligations under this Indenture
to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender,
or any recovery pursuant to any judgment (whether or not entered in accordance with subsection (a))
in any currency other than the Required Currency, except to the extent that such tender or recovery
shall result in the actual receipt, by the payee, of the full amount of the Required Currency
expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required Currency the amount, if
any, by which such actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being obtained for any other
sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day
except a Saturday, Sunday or a legal holiday in The City of New York or a day on which banking
institutions in The City of New York are authorized or required by law or executive order to close.

          SECTION 1.16. Calculation Agent

13

of Securities, any determination of the interest rate on, or other amounts in relation to, such
series of Securities in accordance with the terms of such series of Securities by such calculation
agent shall (in the absence of manifest error) be binding on the Company, the Trustee and all
Securityholders and (in the absence of manifest error) no liability to the Securityholders shall
attach to the calculation agent in connection with the exercise or non-exercise by it of its
powers, duties and discretions.

          SECTION 1.17. Saturdays, Sundays and Legal Holidays

          The terms of the Securities shall provide that, in any case where any Interest Payment Date,
redemption date, maturity or stated maturity of a Security shall not be a Business Day at any Place
of Payment, then (notwithstanding any other provision of this Indenture or the Securities other
than a provision in the Securities that specifically states that such provision shall apply in lieu
of this Section) payments of interest, if any (including additional amounts payable under Section
3.1(b)) or principal need not be made at such Place of Payment on such date, but may be made on the
next succeeding Business Day at such Place of Payment (or such other Business Day as shall be
provided in such Security) with the same force and effect as if made on such Interest Payment Date,
redemption date, maturity or stated maturity, provided that no interest shall accrue on such
payment for the period from and after such Interest Payment Date, redemption date, maturity or
stated maturity, as the case may be.

          SECTION 1.18. Waiver of Jury Trial

          EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY.

          SECTION 1.19. Force Majeure

          In no event shall the Trustee be responsible or liable for any failure or delay in the
performance of its obligations hereunder arising out of or caused by, directly or indirectly,
forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts
of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of
God, and interruptions, loss or malfunctions of utilities, communications or computer (software and
hardware) services; it being understood that the Trustee shall use reasonable efforts which are

          (10) if the amount of payments of principal or interest, if any, on the Securities of
the series may be determined with reference to an index or is otherwise not fixed on the
original issue date thereof, the manner in which such amount shall be determined and the
calculation agent, if any, who shall be appointed and authorized to calculate such amounts;

or Security Registrars or any other agents with respect to the Securities of such series;

          (18)
whether the provisions of Section  3.8 apply to Securities of
the series; or

          (19)
any other terms of the series.

     If the form of Securities of any series is established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action will be certified by the secretary or
any assistant secretary of the Company and delivered to the Trustee concurrently with or prior to
delivery of the Company Order for authentication of such Securities.

          SECTION 2.5. Authentication and Delivery of Securities

          The Company may deliver Securities of any series executed by the Company to the Trustee for
authentication together with the applicable documents referred to below in this Section 2.5, and
the Trustee shall thereupon authenticate and deliver such Securities to or upon the order of the
Company (contained in the Company Order referred to below in this Section 2.5). In authenticating
such Securities and accepting the additional responsibilities under this Indenture in relation to
such Securities the Trustee shall be provided with before the delivery of any such Securities, may
rely conclusively and shall be fully protected in relying upon:

          (1) a Company Order requesting such authentication and setting forth delivery
instructions if the Securities are not to be delivered to the Company;

          (2) any Board Resolution, Officers’ Certificate and/or executed supplemental indenture
referred to in Sections 2.1 and 2.4 by or pursuant to which the terms of the Securities
were established;

          (3) an Officers’ Certificate of the Company certifying the form and terms of the
Securities, stating that the form and terms of the Securities have been established as
required pursuant to Sections 2.1 and 2.4 and comply with the Indenture and covering such
other matters as the Trustee may reasonably request;

          (4) one or more Opinions of Counsel:

	 	(a)	 	to the effect that the form
or forms and terms of such Securities have been established
as required pursuant to Sections 2.1 and 2.4 and comply with
this Indenture;

18

 

	 	(b)	 	to the effect 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 binding obligations of the Company;
	 
	 	(c)	 	to the effect that all laws
and requirements in respect of the execution and delivery by
the Company of the Securities have been complied with; and
	 
	 	(d)	 	covering such other matters
as the Trustee may reasonably request.

     which Opinion of Counsel may state that, with respect to the opinion
in paragraph (c) above, no opinion is given with respect to Federal or
state securities law.

          (5) if the Securities being issued are Original Issue Discount Securities an Officers’
Certificate of the Company setting forth the Yield to Maturity for the Securities and any
other facts required to compute amounts due on acceleration, unless such Yield to Maturity
and other facts are specified in the form of the Securities.

          The Trustee shall have the right to decline to authenticate and deliver any Securities under
this Section if the Trustee, being advised by counsel, determines that the issue of such Securities
is unlawful or if the Trustee in good faith by a trust committee of directors or trustees or
Responsible Officers shall determine that such action would expose the Trustee to personal
liability by existing Holders or affects the Trustee’s rights, duties or immunities under this
Indenture or otherwise.

          SECTION 2.6. Execution of Securities

          The Securities shall be signed on behalf of the Company by any member of its Board of
Directors or the secretary. Any such signature may be the manual or facsimile signature of the
present or any future authorized signatory. Typographical and other minor errors or defects in any
such reproduction of any such signature shall not affect the validity or enforceability of any
Security that has been duly authenticated and delivered by the Trustee.

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

19

 

          SECTION 2.7. Certificate of Authentication

          Only such Securities as shall bear thereon a certificate of authentication substantially in
the form hereinbefore recited, executed by the Trustee by the manual signature of one of its
authorized signatories, shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose. Such certificate by the Trustee upon any Security executed by the
Company shall be conclusive evidence that the Security so authenticated has been duly authenticated
and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

          SECTION 2.8. Denomination and Date of Securities; Payments of Interest

          The Securities of each series shall be issuable in such denominations as shall be specified as
contemplated by Section 2.4. In the absence of any such specification with respect to the
Securities of any series, the Securities of such series shall be issuable in denominations of
$1,000 and integral multiples of $1,000 in excess thereof. The Securities of each series shall be
numbered, lettered, or otherwise distinguished in such manner or in accordance with such plan as
the officers of the Company executing the same may determine with the approval of the Trustee as
evidenced by the execution and authentication thereof.

          Each Security shall be dated the date of its authentication and shall bear interest, if any,
from such date and shall be payable on the dates, in each case, which shall be specified as
contemplated by Section 2.4.

          SECTION 2.9. Registration, Transfer and Exchange

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

          Except as otherwise specified as contemplated by Section 2.4 hereof, any Global Security shall
be exchangeable for Definitive Securities only as provided in this paragraph. A Global Security
shall be exchangeable pursuant to this Section only (i) if the Depositary notifies the Company in
writing that it is unwilling or unable to continue to act as Depositary and a successor Depositary
is not appointed by the Company within 120 days of such notification, (ii) in the event of an Event
of Default, at the request of the Holders, or (iii) at any time if the Company at its option and in
its sole discretion determines that the Global Securities of a particular series should be
exchanged for Definitive Securities of that series. Any Global Security that is exchangeable
pursuant to the preceding sentence shall be exchangeable for, unless otherwise specified or
contemplated by Section 2.4, Definitive Securities bearing interest (if any) at the same rate or
pursuant to the same formula, having the same date of issuance, the same date or

20

 

dates from which such interest shall accrue, the same Interest Payment Dates on which such
interest shall be payable or the manner of determination of such Interest Payment Dates, redemption
provisions, if any, and other terms and of differing denominations aggregating a like amount as the
Global Security so exchangeable. Definitive Securities issued in exchange for Global Securities
shall be registered in the Security Register in such names as from time to time provided by the
Depositary for such Global Securities, pursuant to instructions from the Agent Members, to the
Trustee.

          Any Global Security that is exchangeable pursuant to the preceding paragraph, unless otherwise
specified as contemplated by Section 2.4, shall be exchangeable for Securities issuable in
authorized denominations of a like aggregate principal amount and tenor.

          Except as provided above, owners solely of beneficial interests in a Global Security shall not
be entitled to receive physical delivery of Definitive Securities and will not be considered the
Holders thereof for any purpose under this Indenture.

          In the event that a Global Security is surrendered for redemption in part pursuant to Article
Eleven, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Global Security, without service charge, a new Global Security in a denomination equal to and
in exchange for the unredeemed portion of the principal of the Global Security so surrendered.

          The Agent Members, and any beneficial owners shall have no rights under this Indenture with
respect to any Global Security held on their behalf by a Holder, and such Holder shall 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
prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to
any written certification, proxy or other authorization furnished by a Holder or impair, as between
the Depositary or other clearance service and its Agent Members and Holders, the operation of
customary practices governing the exercise of the rights of a holder of any security, including
without limitation the granting of proxies or other authorization of participants to give or take
any request, demand, authorization, direction, notice, consent, waiver or other action which a
Holder is entitled to give or take under this Indenture.

          In connection with any exchange of interests in a Global Security for Definitive Securities,
as provided in this subsection (a), the Company shall, without unnecessary delay but in any event
not later than the earliest date on which such interests may be so exchanged, deliver to the
Trustee Definitive Securities in aggregate principal amounts equal to the principal amount of such
Global Security or the portion to be exchanged executed by the Company. On or after the earliest
date on which such interests may be so exchanged, such Global Security shall be surrendered by the
Holder to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or from
time to time in part, for Definitive Securities without charge and the Trustee shall authenticate
and deliver, in exchange for each portion of such Global Security, an equal

21

 

aggregate principal amount of Definitive Securities of authorized denominations as the portion
of such Global Security to be exchanged. Any Global Security that is exchangeable pursuant to this
Section 2.9 shall be exchangeable for Securities issuable in the denominations specified as
contemplated by Section 2.4 and registered in the Security Register in such names as the Holder of
such Global Security shall direct. If a Definitive Security is issued in exchange for any portion
of a Global Security after the close of business at the office or agency where such exchange occurs
on any record date and before the opening of business at such office or agency on the relevant
Interest Payment Date, interest will not be payable on such Interest Payment Date in respect of
such Definitive Security, but will be payable on such Interest Payment Date only to the person to
whom payments of interest in respect of such portion of such Global Security are payable.

          The Depositary may grant proxies and otherwise authorize any person, including Agent Members
and persons that may hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture with respect to the Securities.

          Except as otherwise specified pursuant to Section 2.4, Definitive Securities of any series may
be exchanged for a like aggregate principal amount of Definitive Securities of such series of other
authorized denominations containing identical terms and provisions. Securities to be exchanged
shall be surrendered at an office or agency of the Company designated pursuant to Section 3.2 for
such purpose, and the Company shall execute, and the Trustee shall authenticate and deliver, in
exchange therefor the Security or Securities of the same series to each person specified by the
Depositary.

          Except as otherwise specified pursuant to Section 2.4, the Company shall cause to be kept in
the principal Corporate Trust Office of the Trustee 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
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 such Securities; provided no such Security Register shall be
maintained in any office or agency in the United Kingdom.

          Definitive Securities shall be transferable only on the Security Register. Upon surrender for
registration of transfer of any Definitive Security of any series at an office or agency of the
Company designated pursuant to Section 3.2 for such purpose, the Company shall execute, and the
Trustee shall authenticate and deliver, in the name of the designated transferee or transferees,
one or more new Definitive Securities of the same series of any authorized denominations containing
identical terms and provisions, of a like aggregate principal amount.

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

22

 

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

          Every Definitive 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 registered Holder thereof or his attorney duly authorized in writing.

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

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

          SECTION 2.10. Mutilated, Defaced, Destroyed, Lost and Stolen Securities

          If any mutilated Security (including any Global Security) is surrendered to the Trustee, the
Company may execute and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series containing identical terms and provisions and of like amount, and
bearing a number not contemporaneously outstanding.

          If there shall be delivered to the Company and to the Trustee (a) evidence to their
satisfaction of the destruction, loss or theft of any Security (including any Global Security) and
(b) such security or indemnity as may be required by them to save each of them and any agent of any
of them harmless, then, in the absence of notice to the Company or the Trustee that such Security
has been acquired by a bona fide purchaser, the Company shall execute and upon its request the
Trustee shall authenticate and deliver in lieu of any such destroyed, lost or stolen Security a new
Security of the same series containing identical terms and provisions and of like 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, the Company may require the payment
of a sum sufficient to cover any tax or other governmental

23

 

charge that may be imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

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

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

          SECTION 2.11. Cancellation of Securities; Destruction Thereof

          All Securities surrendered for payment, redemption, registration of transfer or exchange, or
for credit against any payment in respect of a sinking or analogous fund, if surrendered to the
Company or any agent of the Company or the Trustee, shall be delivered to the Trustee for
cancellation or, if surrendered to the Trustee, shall be canceled by it and no Securities shall be
issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture.
The Trustee may, subject to the record retention requirements of the Exchange Act, as amended,
dispose of canceled Securities held by it in accordance with its procedures for the disposition of
canceled securities in effect as of the date of such disposition and upon request therefor deliver
a certificate of disposition to the Company unless the Company instructs the Trustee in writing to
return the canceled Securities to the Company. If the Company shall acquire any of the Securities,
such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented
by such Securities unless and until the same are delivered to the Trustee for cancellation.

          SECTION 2.12. Temporary Securities

          Pending the preparation of Definitive Securities for any series, the Company may execute and
the Trustee shall authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form satisfactory to the
Trustee). Temporary Securities of any series shall be issuable as registered Securities without
coupons of any authorized denomination, and substantially in the form of the Definitive Securities
of such series but with such omissions, insertions and variations as may be appropriate for
temporary Securities, all as may be determined by the Company with the concurrence of the Trustee.
Temporary Securities may contain such reference to any provisions of this Indenture as may be
appropriate. Every temporary Security shall be executed by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with like effect, as the
Definitive Securities. Without unreasonable delay the Company shall execute and shall furnish
Definitive Securities of such series and

24

 

thereupon temporary Securities of such series may be surrendered in exchange therefor without
charge at each office or agency to be maintained by the Company for that purpose pursuant to
Section 3.2, and the Trustee shall authenticate and deliver in exchange for such temporary
Securities of such series a like aggregate principal amount of Definitive Securities of the same
series of authorized denominations. Until so exchanged, the temporary Securities of any series
shall be entitled to the same benefits (but shall be subject to all the limitations of rights)
under this Indenture as Definitive Securities of such series.

          SECTION 2.13. Computation of Interest

          Except as otherwise specified pursuant to Section 2.4 for Securities of any series, payments
of 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 2.14. Payment; Interest Rights Preserved

          Except as otherwise provided as contemplated by Section 2.4 with respect to any series of
Securities, interest on any series of Securities which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security
(or one or more Predecessor Securities) is registered in the Security Register at the close of
business on the Regular Record Date for such interest.

          In the case of Securities where payment is to be made in U.S. dollars, payment at any paying
agent’s office outside The City of New York will be made in U.S. dollars by check drawn on, or, at
the request of the Holder, by wire transfer of same-day funds to a U.S. dollar account maintained
by the payee with, a bank in The City of New York.

          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 is herein called “Deferred Interest.” Deferred
Interest on any Security of any series shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue then of having been such Holder, and such Deferred Interest
may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:

          (a) The Company may elect to make payment of any Deferred Interest to the Persons in whose
names the Securities of such series (or their respective Predecessor Securities) are registered in
the Security Register at the close of business on a Special Record Date for the payment of such
Deferred Interest, which shall be fixed in the following manner. The Company shall notify the
Trustee in writing of the amount of Deferred Interest proposed to be paid on each 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
Deferred Interest or shall make arrangements satisfactory to the Trustee for such deposit

25

 

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 Deferred Interest as in this clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such Deferred Interest in
respect of such Securities of such series which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after the receipt by the
Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of
such Special Record Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Deferred Interest and the Special Record Date therefor to be given in
the manner and to the extent provided in Section 1.6, not less than 10 days prior to such Special
Record Date. Notice of the proposed payment of such Deferred Interest on the Securities of such
series and the Special Record Date therefor having been so given, such Deferred Interest on the
Securities of such series shall be paid to the Persons in whose names such Securities (or their
respective Predecessor Securities) are registered in the Security Register at the close of business
on the Special Record Date; or

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

          Subject to the foregoing provisions of this Section 2.14, 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 interest, which were carried
by such other Security.

          SECTION 2.15. Persons Deemed Owners

          Prior to due presentment of a Security for registration of transfer, the Company, the Trustee
and any agent of the Company or the Trustee shall treat the Person in whose name such Security is
registered in the Security Register as the owner of such Security for the purpose of receiving
payment of principal of and (subject to Section 2.14) interest (including additional amounts
payable under Section 3.1(b)), if any, on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary.

          SECTION 2.16. CUSIP Numbers

          The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and,
if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders;
provided, that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed

26

 

only on the other identification numbers printed on the Securities, and any such redemption
shall not be affected by any defect in or omission of such numbers. The Company will promptly
notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE THREE

COVENANTS OF THE COMPANY

          SECTION 3.1. Payment of Principal and Interest

          (a) The Company covenants and agrees for the benefit of the Holders of each series of
Securities that it will duly and punctually pay or cause to be paid in U.S. dollars the principal
of and interest, if any, on each of the Securities of such series at the place or places, at the
respective times and in the manner provided in such Securities. Each installment of interest or
any payment of principal on the Securities of any series may be paid by mailing checks for such
interest or principal payable to or upon the written order of the Holders of Securities entitled
thereto as they shall appear on the Security Register and in no event shall payments be made to, or
upon the written order of, persons other than Holders of Securities entitled to payment whose names
appear on the Security Register.

          (b) The Company hereby further agrees that any amounts to be paid by the Company with respect
to each Security shall be paid without deduction or withholding for any and all present and future
taxes, levies, imposts or other governmental charges whatsoever imposed, assessed, levied or
collected by or for the account of the United Kingdom or any political subdivision or taxing
authority thereof or therein unless the Company is required to withhold or deduct any and all
taxes, levies, imposts or other governmental charges by law or by the interpretation or
administration thereof by the United Kingdom or any political subdivision or taxing authority
thereof or therein. The Company hereby further agrees that if deduction or withholding of any such
taxes, levies, imposts or other governmental charges whatsoever imposed, assessed, levied or
collected by or for the account of the United Kingdom or any political subdivision or taxing
authority thereof or therein is required, the Company will (subject to compliance by the Holder or
beneficial owner of such Security with any relevant administrative requirements) pay such
additional amount (“Additional Amount”) in respect of principal, premium, if any, interest, if any,
and sinking fund payments, if any, as may be necessary in order that the net amounts paid to the
Holder of such Security or the Trustee under this Indenture, as the case may be, after such
deduction, or withholding, shall equal the respective amounts of principal, premium, if any,
interest, if any, and sinking fund payments, if any, as specified in the Security, to which such
Holder or the Trustee is entitled; provided, however, that the foregoing shall not
apply to (i) any present or future taxes, levies, imposts or other governmental charges which would
not have been so imposed, assessed, levied or collected but for the fact that the Holder or
beneficial owner of such Security is or has been a domiciliary, national or resident of, or
engaging or having been engaged in business or maintaining or having maintained a permanent
establishment or being or having been physically present in, the United Kingdom or such

27

 

political subdivision or otherwise having or having had some connection with the United
Kingdom or such political subdivision other than the holding or ownership of a Security, or the
collection of principal, premium, if any, and interest, if any, on, or the enforcement of, a
Security, (ii) any present or future taxes, levies, imposts or other governmental charges which
would not have been so imposed, assessed, levied or collected but for the fact that, where
presentation is required, such Security was presented more than thirty days after the date such
payment became due or was provided for, whichever is later, (iii) any present or future taxes,
levies, imposts or other governmental charges which are payable otherwise than by deduction or
withholding from payments on or in respect of such Security, (iv) any present or future taxes,
levies, imposts or other governmental charges which would not have been so imposed, assessed,
levied or collected but for (A) the failure to comply with any certification, identification or
other reporting requirements concerning the nationality, residence, identity or connection with the
United Kingdom or any political subdivision or authority thereof by the Holder or beneficial owner
of such Security, or (B) the failure to make any declaration or other similar claim or to satisfy
any information or reporting requirement that, in the case of (A) or (B), is required or imposed by
statute, treaty, regulation or administrative practice of the United Kingdom or such political
subdivision or authority as a precondition to exemption from all or part of such taxes, levies,
imposts or other governmental charges, (v), any deduction or withholding that is payable as a
result of or pursuant to any European Union Directive on the taxation of savings implementing the
conclusions of the ECOFIN Council Meeting of 26-27 November 2000 or any law implementing or
complying with, or introduced in order to conform to, such Directive, (vi) any present or future
taxes, levies, imposts or other governmental charges that the Holder would have been able to avoid
by presenting such Security to another paying agent, (vii) any present or future taxes, levies,
imposts or other governmental charges (A) that would not have been so imposed, assessed, levied or
collected if the beneficial owner of such Security had been the Holder of such Security or (B)
which, if the beneficial owner of such Security held the Security as the Holder of such Security,
would have been excluded pursuant to clauses (i) through (vi) inclusive above, or (viii) any
estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other
governmental charge or (ix) any combination of the foregoing clauses (i) through (viii); and
provided, further, that in the event the Company fails to pay the full amount of
principal, premium, if any, interest, if any, or a sinking fund payment, if any, when due as a
result of any deduction or withholding permitted by clauses (i) through (viii) above, the Company
shall deliver to the Trustee an Officers’ Certificate confirming that such a deduction or
withholding has been made, upon which the Trustee may conclusively rely.

          SECTION 3.2. Offices for Payments, etc.

          So long as any Securities remain outstanding, the Company will maintain in the Borough of
Manhattan, The City of New York (unless otherwise provided pursuant to Section 2.4) an office or
agency (a “Security Registrar”) where (x) Securities may be presented or surrendered for
registration of transfer or for exchange, (y) Securities may be presented or surrendered for
payment and (z) notices and demands in respect of the

28

 

Securities and this Indenture may be served. The Security Registrar shall keep a register of
the Securities and of their transfer and exchange. The Company will give to the Trustee written
notice of the location of any such office or agency and of any change of location thereof. Unless
otherwise specified with respect to the Securities of any series in accordance with Section 2.4,
the Company hereby initially designates the Corporate Trust Office as the office to be maintained
by it for each such purpose. In case the Company shall fail to so designate or maintain any such
office or agency or shall fail to give such notice of the location or of any change in the location
thereof, presentations and demands may be made and notices may be served at the Corporate Trust
Office.

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

          SECTION 3.3. Appointment to Fill a Vacancy in Office of Trustee

          The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will
appoint, in the manner provided in Section 6.10, a Trustee, so that there shall at all times be a
Trustee with respect to each series of Securities.

          SECTION 3.4. Paying Agents

          Whenever the Company shall appoint any paying agent other than the Trustee with respect to the
Securities of any series, it will cause each such paying agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions
of this Section, that it will:

          (a) comply with the provisions of the Trust Indenture Act applicable to it as a paying agent;

          (b) hold all sums held by it as paying agent for the payment of the principal of or interest
(including additional amounts payable under Section 3.1(b)), if any, on such Securities in trust
for the benefit of the Holders of the Securities entitled thereto, or for the benefit of the
Trustee, as the case may be, until such sums in cash shall be paid out to such Holders or otherwise
as herein provided;

          (c) give the Trustee notice (pursuant to Section 1.5) of any failure by the Company in the
making of any deposit with such paying agent or for the payment of principal of or interest
(including additional amounts payable under Section 3.1(b)), if any, on such Securities which shall
have become payable and of any default by the

29

 

Company in making any payment of principal of or interest, if any, on such Securities when the
same shall be due and payable; and

          (d) at any time during the continuance of any such failure set forth in clause (c) above, upon
the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such
paying agent.

          The Company will, on or prior to each due date of the principal of or interest on the
Securities of such series, deposit with the paying agent a sum sufficient to pay such principal or
interest, if any, so becoming due, such sum to be held as provided in the Trust Indenture Act, and
(unless such paying agent is the Trustee) the Company will promptly notify the Trustee of any
failure to take such action.

          If the Company shall act as paying agent with respect to the Securities of any series, it
will, on or before each due date of the principal of or interest, if any, on the Securities of such
series, set aside, segregate and hold in trust for the benefit of the Holders of the Securities of
such series a sum sufficient to pay such principal or interest so becoming due. The Company will
promptly notify the Trustee of any failure to take such action.

          Anything in this Section to the contrary notwithstanding, the Company may at any time, for the
purpose of obtaining a satisfaction and discharge with respect to one or more or all series of
Securities hereunder, or for any other reason, pay or cause to be paid to the Trustee all sums held
in trust for any such series by the Company or any paying agent hereunder, as required by this
Section 3.4, such sums to be held by the Trustee upon the trusts herein contained.

          Anything in this Section to the contrary notwithstanding, the requirement of the Trust
Indenture Act that paying agents hold sums in trust as provided in this Section is subject to the
provisions of Sections 10.4 and 10.5.

          SECTION 3.5. Compliance Certificates

          On or before March 31 in each year if Securities are then Outstanding, the Company will
deliver to the Trustee a brief certificate from the chief executive officer, finance director or
principal accounting officer of the Company as to his or her knowledge of the Company’s compliance
with all conditions and covenants applicable thereto under this Indenture. For purposes of this
Section 3.5, such compliance shall be determined without regard to any period of grace or
requirement of notice under this Indenture.

          SECTION 3.6. Limitation on Liens

          (a) Nothing in this Indenture or in the Securities shall in any way restrict or prevent the
Company or any Subsidiary of the Company from incurring, assuming or guaranteeing any indebtedness;
provided that the Company will not, and will

30

 

not permit any of its Significant Subsidiaries to, incur, assume, guarantee or suffer to exist
indebtedness for money borrowed (hereinafter in this Article Three referred to as “Debt”), secured
by a mortgage, pledge, security interest, lien, fixed or floating charge or other encumbrance
(mortgages, pledges, security interests, liens, fixed or floating charges and other encumbrances
being hereinafter in this Article Three referred to as a “lien” or “liens”) upon any Restricted
Assets without effectively providing that the Debt due under this Indenture and the Securities
(together with, if the Company shall so determine, any other Debt of the Company or any of its
Subsidiaries then existing or thereafter created ranking equally with the Securities) shall be
secured equally and ratably with (or prior to) such Debt, so long as such Debt shall be so secured,
except that this Section 3.7(a) shall not apply to Debt secured by:

     (1) liens on shares of stock or assets or indebtedness of any corporation existing at
the time such corporation becomes a Significant Subsidiary of the Company or of a
Significant Subsidiary;

     (2) liens on shares of stock or assets or indebtedness existing at the time of
acquisition thereof or to secure the payment of all or any part of the purchase price
thereof or to secure any Debt incurred prior to, at the time of, or within twelve months
after, in the case of shares of stock, the acquisition of such shares and, in the case of
assets, the later of the acquisition, the completion of construction (including any
improvements on an existing asset) or the commencement of commercial operation of such
asset, which Debt is incurred for the purpose of financing all or any part of the purchase
price thereof;

     (3) liens existing at the date of this Indenture;

     (4) liens for taxes, assessments, or governmental charges or levies not yet delinquent
or being contested in good faith by appropriate proceedings diligently conducted, if such
reserve or other appropriate provision, if any, as shall be required by generally accepted
accounting principles in the United Kingdom shall have been made therefor:

     (5) liens arising by operation of law and not securing amounts more than 90 days
overdue or otherwise being contested in good faith;

     (6) any lien over any credit balance or cash in any account with a financial
institution arising solely by operation of law or granted in the ordinary course of
business as security for any loan or other financial accommodation (not exceeding the
amount of such credit balance or cash) made available by such financial institution or its
affiliates to the Company or any Subsidiary in jurisdictions where, due to regulatory, tax,
foreign exchange control or other similar reasons, intercompany loans are restricted or
impracticable and such loan or financial accommodation is obtained in lieu of such
intercompany loans;

31

 

     (7) rights of financial institutions to offset credit balances in connection with the
operation of cash management programs established for the benefit of the Company and/or any
Subsidiary;

     (8) any liens incurred or deposit made in the ordinary course of business, including,
but not limited to, (A) any mechanics’, materialmen’s, carriers’, workmen’s, vendor’s or

     (9) liens on shares of stock or assets or indebtedness of any corporation existing at
the time such corporation is acquired by, merged with or into, or consolidated or
amalgamated with the Company or any Significant Subsidiary or at the time of a sale, lease
or other disposition of the assets of a corporation as an entirety or substantially as an
entirety to the Company or any Significant Subsidiary;

     (10) any liens created by the Company or a Significant Subsidiary over its assets as
part of a project financing (including the shares of any special purpose corporation) to
secure Debt incurred to finance the project where the right of recovery is limited to the
assets of the project being financed; and

     (11) any extension, renewal or replacement (or successive extensions, renewals or
replacements) in whole or in part, of any lien permitted under the foregoing clauses (1) to
(10), inclusive, or of any Debt secured thereby; provided that the principal amount of Debt
secured thereby shall not exceed the principal amount of Debt so secured, or capable of
being so secured under the written arrangements under which the original lien arose, at the
time of such extension, renewal or replacement and that such extension, renewal or
replacement lien shall be limited to all or any part of the same shares of stock or assets
or indebtedness that secured the lien extended, renewed or replaced (plus improvements on
such assets), or shares of stock issued or indebtedness or assets received in substitution
or exchange therefor.

          (b) Notwithstanding the provisions of clause (a) of this Section 3.6, the Company or any
Significant Subsidiary may incur, assume, guarantee or suffer to exist Debt secured by a lien or
liens which would otherwise be subject to the foregoing restrictions in an aggregate amount which,
together with all other such Debt of the Company and its Significant Subsidiaries and their
Attributable Debt in respect of Sale and Lease-Back Transactions (as defined below) existing at
such time (other than Attributable Debt in respect of Sale and Lease-Back Transactions permitted
because the Company or any Significant Subsidiary would be entitled to incur, assume, guarantee or
suffer to exist such Debt secured by a lien on the assets to be leased without equally and ratably
securing the Debt due under this Indenture and the Securities pursuant to clause

32

 

(a) of this Section 3.6 and other than Sale and Lease-Back Transactions, the proceeds of which
have been applied in accordance with Section 3.7(a)(2)), does not at the time exceed 10% of
Consolidated Net Tangible Assets.

          (c) The Trustee, subject to Sections 6.1 and 6.3, shall be provided with Opinion of Counsel as
conclusive evidence that any transaction complies with the provisions of this Section 3.6. The
foregoing is not intended to limit the generality of Section 6.3(d) or to require the Trustee to
request an Opinion of Counsel in connection with any such transaction.

          SECTION 3.7. Limitation on Sale and Lease Back Transactions

          (a) The Company will not itself enter into, and will not permit any of its Significant
Subsidiaries to enter into, any arrangement with any Person providing for the leasing by the
Company or any of its Significant Subsidiaries, as the case may be, of any Restricted Assets
(except a lease for a temporary period not to exceed three years and except for leases between the
Company and/or a Significant Subsidiary of the Company and a Subsidiary of the Company) which have
been or are to be sold or transferred by the Company or any Significant Subsidiary to such Person
(herein referred to as a “Sale and Lease-Back Transaction”) unless, after giving effect thereto,
the aggregate amount of all Attributable Debt with respect to all such Sale and Lease Back
Transactions plus all Debt of the Company and its Significant Subsidiaries incurred, assumed or
guaranteed and secured by a lien or liens (with the exception of Debt secured by a lien on
Restricted Assets that the Company and its Significant Subsidiaries would be entitled to incur,
assume, guarantee or suffer to exist without equally and ratably securing the Debt due under this
Indenture and the Securities pursuant to clause (a) of Section 3.6) does not exceed 10% of
Consolidated Net Tangible Assets. This Section 3.7 shall not apply to any Sale and Lease Back
Transaction if:

          (1) the Company at any Significant Subsidiary, as the case may be, would be entitled
to incur, assume, guarantee or suffer to exist Debt secured by a lien or liens on the
Restricted Assets to be leased without equally and ratably securing the Debt due under this
Indenture and the Securities pursuant to clause (a) of Section 3.6, or

          (2) the Company or any Significant Subsidiary, as the case may be, within the twelve
months preceding the sale or transfer or the twelve months following the sale or transfer,
regardless of whether such sale or transfer may have been made by the Company or such
Significant Subsidiary, applies in the case of a sale or transfer for cash, an amount equal
to the net proceeds thereof and, in the case of a sale or transfer otherwise than for cash,
an amount equal to the fair value of the Restricted Assets so leased at the time of
entering into such arrangement (as determined by the Board of Directors of the Company or
such Significant Subsidiary), (i) to the retirement (other than any retirement of Debt owed
to the Company or any Significant Subsidiary or any retirement of Debt subordinated to the
Securities) of indebtedness for money borrowed, incurred or

33

 

assumed by the Company or such Significant Subsidiary which by its terms matures at,
or is extendible or renewable at the option of the obligor to, a date more than twelve
months after the date of incurring, assuming or guaranteeing such Debt or (ii) to
investment in any Restricted Assets of the Company or such Significant Subsidiary.

          (b) The Trustee, subject to Sections 6.1 and 6.3, may receive in Opinion of Counsel as
conclusive evidence that any transaction complies with the provisions of this Section 3.7. The
foregoing is not intended to limit the generality of Section 6.3(d) or to require the Trustee to
request an Opinion of Counsel in connection with any such transaction.

          SECTION 3.8. Change of Control Repurchase Event

          (a) The provisions of this Section 3.8 shall apply to a series of Securities if
the instrument establishing the terms of such series pursuant to Section 2.4 hereof so
indicates.

          (b) If a Change of Control Repurchase Event occurs, unless the Company has
exercised its right to redeem such series of Securities as described in Article Eleven, the Company
will make an offer to each Holder of Securities of such series to repurchase all or any part (in
integral multiples of $1,000) of that Holder’s Securities at a repurchase price in cash equal to
101% of the aggregate principal amount of Securities repurchased plus any accrued and unpaid
interest on such Securities repurchased to the date of purchase. Within 30 days following any
Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but
after the public announcement of the Change of Control, the Company will mail a notice to each
Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or
may constitute the Change of Control Repurchase Event and offering to repurchase Securities on the
payment date specified in the notice, which date will be no earlier than 30 days and no later than
60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of
consummation of the Change of Control, state that the offer to purchase is conditioned on the
Change of Control Repurchase Event occurring on or prior to the payment date specified in the
notice. To the extent that the provisions of any securities laws or regulations conflict with the
Change of Control Repurchase Event provisions of such series of Securities, the Company will comply
with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under the Change of Control Repurchase Event provisions of such series of Securities by
virtue of such conflict.

          (c) On a Change of Control Repurchase Event payment date, the Company will, to the
extent lawful:

               (1) accept for payment all Securities or portions of Securities properly
tendered pursuant to the offer;

               (2) deposit with the paying agent an amount equal to the aggregate
purchase price in respect of all Securities or portions of Securities properly tendered;
and

               (3) deliver or cause to be delivered to the Trustee the Securities
properly accepted, together with an Officers’ Certificate stating the aggregate principal
amount of such Securities being purchased by the Company.

          (d) The paying agent will promptly mail to each Holder of Securities properly
tendered the purchase price for the Securities, and the Trustee will promptly authenticate and mail
(or cause to be transferred by book-entry) to each Holder a new Security equal in principal amount
to any unpurchased portion of any Securities surrendered; provided that each new Security will be in a principal amount of $1,000 or an
integral multiple of $1,000.

          (e) The Company will not be required to make an offer to repurchase Securities
upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the
times and otherwise in compliance with the requirements for an offer made by the Company and such
third party purchases all Securities properly tendered and not withdrawn under its offer.

          (f) For the purposes of this Section 3.8, the following terms shall have the
meanings indicated:

          The
term “Below Investment Grade Rating Event” means Securities of the relevant series are
rated below Investment Grade by both Rating Agencies on any date from the date of the public notice
of an arrangement that could result in a Change of Control until the end of the 60-day period
following public notice of the occurrence of a Change of Control (which period shall be extended so
long as the rating of such Securities is under publicly announced consideration for possible
downgrade by either of the Rating Agencies); provided that a Below Investment Grade Rating Event
otherwise arising by virtue of a particular reduction in rating shall not be deemed to have
occurred in respect of a particular Change of Control (and thus shall not be deemed a Below
Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event
hereunder) if the Rating Agencies making the reduction in rating to which this definition would
otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request
that the reduction was the result, in whole or in part, of any event or circumstance comprised of
or arising as a result of, or in respect of, the applicable change of control (whether or not the
applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating
Event).

          The
term “Change of Control” means any Person or any Persons acting in concert (as defined
in the City Code on Takeovers and Mergers), or any Person or Persons acting on behalf of any such
Person(s), the (“Relevant Person”) at any time is/are or become(s) interested (within the meaning
of Part VI of the UK Companies Act 1985) in (A) more than 50 percent of the issued or allotted
ordinary share capital of the Company or (B) such number of shares in the capital of the Company as
carry more than 50 percent of the voting rights normally exercisable at a general meeting of the
Company, provided that a Change of Control shall not be deemed to have occurred if all or
substantially all of the shareholders of the Relevant Person are, or immediately prior to the event
which would otherwise have constituted a Change of Control were, the shareholders of the Company
with the same (or substantially the same) pro rata interests in the share capital of the Relevant
Person as such shareholders have, or as the case may be, had, in the share capital of the
Company.

          The term “Change of Control Repurchase Event” means the occurrence of both a Change of
Control and a Below Investment Grade Rating Event.

          The term “Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent
under any successor rating categories of Moody’s); a rating of BBB- or better by S&P (or its
equivalent under any successor rating categories of S&P); and the equivalent investment grade
credit rating from any additional Rating Agency or Rating Agencies selected by us.

          The term “Moody’s” means Moody’s Investor Services Inc.

          The term “Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s
or S&P ceases to rate the Securities of a relevant series or fails to make a rating of such
Securities publicly available for reasons outside of the Company’s control, a “nationally
recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under
the Securities Exchange Act of 1934, as amended, selected by the Company (as certified by a
resolution of the Board of Directors) as a replacement agency for Moody’s or S&P, or both, as the
case may be.

          The term “S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill,
Inc.

Significant Subsidiary’s affairs, and the continuance of any such decree or order unstayed and in
effect for a period of sixty consecutive days; or

          (e) the institution by the Company or any Significant Subsidiary of proceedings to be
adjudicated a bankrupt or insolvent or the consent by the Company or any Significant Subsidiary to
the institution of bankruptcy or insolvency proceedings against the Company or such Significant
Subsidiary or (other than under or in connection with a scheme of amalgamation or reconstruction
not involving bankruptcy or insolvency) the passing of a resolution that the Company or any
Significant Subsidiary be wound up or the filing of a petition or answer or consent seeking
reorganization or relief under any applicable bankruptcy, insolvency or similar law of the United
States of America or the United Kingdom, or the consent by the Company or any Significant
Subsidiary to the filing of such petition or to the appointment of a receiver, liquidator,
assignee, trustee, sequestrator or similar official of the Company or any Significant Subsidiary or
of any substantial part of the property of the Company or any Significant Subsidiary, or the making
by the Company of any Significant Subsidiary of an assignment for the benefit of creditors, or the
admission by the Company or any Significant Subsidiary in writing of its inability to pay its debts
generally as they become due, or (other than under or in connection with a scheme of amalgamation
or reconstruction not involving bankruptcy or insolvency) the taking of action by the Board of
Directors of the Company or by the analogous body of any Significant Subsidiary authorizing or
directing any such action;

          (f) default by the Company or any of its Significant Subsidiaries under any mortgage,
indenture or instrument under which there may be issued or by which there may be secured or
evidenced any indebtedness for money borrowed by the Company or any of its Significant Subsidiaries
(or the payment of which is guaranteed by the Company or any of its Significant Subsidiaries),
other than indebtedness owed to the Company or a Significant Subsidiary, whether such indebtedness
or guarantee now exists or is created after the date of this Indenture, which default:

37

 

          (1) is caused by a failure to pay principal of, or interest or premium, if any, on
such indebtedness prior to the expiration of any applicable grace period (and in any event
not less than 15 days from the original due date for payment thereof) provided in such
indebtedness or, in the case of any such indebtedness of a third party guaranteed by the
Company or any of its Significant Subsidiaries, is caused by a failure of the Company or
such Significant Subsidiary, as the case may be, to make any payment due in respect of such
guarantee prior the expiration of any applicable grace period (and in any event not less
than 15 days from the original due date for payment thereof) (“payment default”), unless,
in any of the above cases, in the opinion of the Trustee, the Company or the relevant
Significant Subsidiary, as the case may be, is contesting in good faith and by appropriate
proceedings that such amounts are due; or

          (2) results in the acceleration of such indebtedness prior to its maturity, other than
any such indebtedness of any Person which becomes a Significant Subsidiary following its
acquisition by the Company or any Subsidiary of the Company and which indebtedness of such
Person is accelerated as a result of events or circumstances directly related to such
acquisition and which accelerated indebtedness of such Person is discharged in full by or
on behalf of the Company or the relevant Significant Subsidiary within 5 days after the
acceleration thereof;

          and, in each case, the principal amount of any such indebtedness, together with the principal
amount of any other such indebtedness under which there has been a payment default or the maturity
of which has been so accelerated, aggregates to an amount at least equal to the greater of (i) 1%
of Consolidated Net Worth and (ii) $50,000,000 (or the foreign currency equivalent thereof); or

          (g) any other Event of Default provided in the supplemental indenture or in or pursuant to
resolutions of the Board of Directors of the Company under which such series of Securities is
issued or in the form of Security of such series.

          If an Event of Default described in clause (a), (b), (c) (if the Event of Default under clause
(c) is with respect to less than all series of Securities then Outstanding), (f) or (g) above
occurs and is continuing with respect to a series of Securities, then, and in each and every such
case, unless the principal of all of the Securities of such series shall have already become due
and payable, the Trustee in its discretion may, and if so requested by the Holders of not less than
25% in aggregate principal amount of the Securities of such series then Outstanding hereunder
(voting as a separate class) shall, by notice in writing to the Company, declare the entire
principal (or, if the Securities of such series are Original Issue Discount Securities, such
portion of the principal amount as may be specified in the terms of such series) of all the
Securities of such series and the interest (including additional amounts payable under Section
3.1(b)) accrued thereon, if any, to be due and payable immediately, and upon any such declaration
the same shall become immediately due and payable. If an Event of Default described in clause (c)
(if the Event of Default under clause (c) is with respect to all

38

 

series of Securities then Outstanding), (d) or (e) occurs and is continuing, then and in each
and every such case, unless the principal of all the Securities shall have already become due and
payable, the Trustee in its discretion may, and if so requested by the Holders of not less than 25%
in aggregate principal amount of all the Securities then Outstanding hereunder (voting as one
class) shall, by notice in writing to the Company (and to the Trustee if given by Securityholders),
declare the entire principal (or, if any Securities are Original Issue Discount Securities, such
portion of the principal as may be specified in the terms thereof) of all the Securities then
Outstanding and interest (including additional amounts payable under Section 3.1(b)) accrued
thereon, if any, to be due and payable immediately, and upon any such declaration the same shall
become immediately due and payable.

          The foregoing provisions, however, are subject to the condition that if, at any time after the
principal (or, if the Securities are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms thereof) of the Securities of any series (or of all the
Securities, as the case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained or entered as
hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to
pay all matured installments of interest (including additional amounts payable under Section
3.1(b)) upon all the Securities of such series (or of all the Securities, as the case may be) and
the principal of any and all Securities of such series (or of all the Securities, as the case may
be) which shall have become due otherwise than by acceleration (with interest upon such principal
and, to the extent that payment of such interest is enforceable under applicable law, on overdue
installments of interest, at the same rate of interest or Yield to Maturity (in the case of
Original Issue Discount Securities) specified in the Securities of such series (or at the
respective rates of interest or Yields to Maturity of all the Securities, as the case may be, to
the date of such payment or deposit) and such amount as shall be sufficient to cover reasonable
compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Trustee except as a result of negligence or bad
faith, and if any and all Events of Default with respect to the Securities of that Series, other
than the non payment of the principal of Securities of that series which shall have become due by
acceleration, shall have been cured, waived or otherwise remedied as provided herein, then and in
every such case the Holders of a majority in aggregate principal amount of all the Securities of
such series, voting as a separate class (or of all the Securities, as, the case may be, voting as a
single class) then Outstanding, by written notice to the Company and to the Trustee, may waive all
defaults with respect to such series (or with respect to all the Securities, as the case may be)
and rescind and annul such declaration and its consequences, but no such waiver or rescission and
annulment shall extend to or shall affect any subsequent default or shall 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

39

 

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, (including additional amounts payable under Section 3.1(b)), if any,
thereon and all other amounts owing thereunder, shall constitute payment in full of such Original
Issue Discount Securities.

          SECTION 5.2. Collection of Indebtedness by Trustee; Trustee May Prove Debt

          The Company covenants that (a) in case default shall be made in the payment of any interest on
any of the Securities of any series when such interest shall have become due and payable and such
default shall have continued for a period of thirty days or (b) in case default shall be made in
the payment of any principal of any of the Securities of any series when the same shall have become
due and payable, whether upon maturity of the Securities of such series or upon any redemption or
by declaration or otherwise, then upon demand of the Trustee, the Company will pay to the Trustee,
for the benefit of the Holders of the Securities of such series, the whole amount that then shall
have become due and payable on all Securities of such series for principal or interest, as the case
may be (with interest to the date of such payment upon the overdue principal and, to the extent
that payment of such interest is enforceable under applicable law, on overdue installments of
interest at the same rate as the rate of interest or Yield to Maturity (in the case of Original
Issue Discount Securities) specified in the Securities of such series); and in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of collection, including
reasonable compensation to the Trustee and each predecessor Trustee, their respective agents,
attorneys and counsel, and any expenses and liabilities incurred, and all advances made, by the
Trustee and each predecessor Trustee except as a result of its negligence or bad faith.

          Until such demand is made by the Trustee, the Company may pay the principal of and interest on
the Securities of any such series to the registered Holders in the Security Register, whether or
not the principal of and interest on the Securities of such series is overdue.

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

          In case of any judicial proceeding relating to the Company or any other obligor upon the
Securities, or the property or creditors of the Company or any such obligor, the Trustee shall be
entitled and empowered, by intervention in such proceeding

40

 

or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding.

          The Trustee shall be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute all amounts received with respect to the claims
of the Securityholders and of the Trustee on their behalf, and any trustee, receiver, or
liquidator, custodian or other similar official is hereby authorized by each of the Securityholders
to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of
payments directly to the Securityholders, to pay to the Trustee such amounts as shall be sufficient
to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective
agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances
made, by the Trustee and each predecessor Trustee except as a result of negligence or willful
misconduct and all other amounts due to the Trustee or any predecessor Trustee pursuant to Section
6.7.

          No provision of this Indenture shall be deemed to authorize the Trustee to authorize or
consent to or vote for or accept or adopt on behalf of any Securityholder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities of any series or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of
any Securityholder in any such proceeding except, as aforesaid, to vote for the election of a
trustee in bankruptcy or similar person.

          All rights of action and of asserting claims under this Indenture, or under any of the
Securities, may be enforced by the Trustee without the possession of any of the Securities or the
production thereof in any trial or other proceedings relative thereto, and any such action or
proceedings instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and
compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys,
shall be for the ratable benefit of the Holders of the Securities in respect of which such action
was taken.

          In any proceedings brought by the Trustee (and also any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party) the
Trustee shall be held to represent all the Holders of the Securities in respect of which such
action was taken, and it shall not be necessary to make any Holders of such Securities parties to
any such proceedings.

          SECTION 5.3. Application of Moneys Collected

          Any moneys collected by the Trustee pursuant to this Article in respect of any series shall be
applied in the following order at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal or interest, upon presentation of the several
Securities in respect of which moneys have been collected and stamping (or otherwise noting)
thereon the payment, or issuing Securities of such series in reduced principal amounts in exchange
for the presented Securities of like series if only partially paid, or upon surrender thereof if
fully paid:

41

 

          FIRST: To the payment of costs and expenses applicable to such series in respect of which
moneys have been collected, including reasonable compensation to the Trustee and each predecessor
Trustee and their respective agents and attorneys and of all expenses and liabilities incurred, and
all advances made, by the Trustee and each predecessor Trustee except as a result of negligence or
willful misconduct, and all other amounts due to the Trustee or any predecessor Trustee pursuant to
Section 6.7;

          SECOND: In case the principal 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
(including any additional amounts payable pursuant to Section 3.1(b))on the Securities of such
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) upon the overdue installments
of interest at the same rate as the rate of interest or Yield to Maturity (in the case of original
Issue Discount Securities) specified in such Securities, such payments to be made ratably to the
persons entitled thereto, without discrimination or preference;

          THIRD: In case the principal of the Securities of such series in respect of which moneys have
been collected shall have become and shall be then due and payable, to the payment of the whole
amount (including any additional amounts payable pursuant to Section 3.1(b)) then owing and unpaid
upon all the Securities of such series for principal and interest, with interest upon the overdue
principal, and (to the extent that such interest has been collected by the Trustee) upon overdue
installments of interest at the same rate as the rate of interest or Yield to Maturity (in the case
of Original Issue Discount Securities) specified 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 interest or Yield to Maturity, without
preference or priority of principal over interest or Yield to Maturity, or of interest or Yield to
Maturity over principal, 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 accrued and unpaid interest or Yield to Maturity; and

          FOURTH: To the payment of the remainder, if any, to the Company.

          SECTION 5.4.  Suits for Enforcement

          In case an Event of Default has occurred, has not been waived and is continuing, the Trustee
may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by
such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce
any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or in aid of the
exercise of any power granted in this Indenture or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

42

 

          SECTION 5.5. Restoration of Rights and Remedies

          In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned for any reason, or shall have been determined
adversely to the Trustee, then and in every such case the Company and the Trustee shall be restored
respectively to their former positions and rights hereunder, and all rights, remedies and powers of
the Company, the Trustee and the Securityholders shall continue as though no such proceedings had
been taken.

          SECTION 5.6. Limitations on Suits

          No Holder of any Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in equity or in
bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of
a trustee, receiver, liquidator, custodian or other similar official or for any other remedy
hereunder, unless such Holder previously shall have given to the Trustee written notice of default
with respect to Securities of such series and of the continuance thereof, as hereinbefore provided,
and unless also the Holders of not less than 25% in aggregate principal amount of the Securities of
such series then Outstanding shall have made written request upon the Trustee to institute such
action or proceedings in its own name as trustee hereunder and shall have offered to the Trustee
such indemnity as it may reasonably require against the costs, expenses and liabilities to be
incurred therein or thereby and the Trustee for sixty days after its receipt of such notice,
request and offer of indemnity shall have failed to institute any such action or proceeding and no
direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 5.9, it being understood and intended, and being expressly covenanted by the Holder of
every Security with every other Holder and the Trustee, that no one or more Holders of Securities
of any series shall have any right in any manner whatever by virtue or by availing of any provision
of this Indenture to affect, disturb or prejudice the rights of any other such Holder of
Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or
to enforce any right under this Indenture, except in the manner herein provided and for the equal,
ratable and common benefit of all Holders of Securities of the applicable series. For the
protection and enforcement of the provisions of this Section, each and every Securityholder and the
Trustee shall be entitled to such relief as can be given either at law or in equity.

          SECTION 5.7. Unconditional Right of Securityholders to Institute Certain Suits

          Notwithstanding any other provision in this Indenture and any provision of any Security, the
right of any Holder of any Security to receive payment of the principal of and interest (including
additional amounts payable pursuant to Section 3.1(b)), if any, on such Security on or after the
respective due dates expressed in such Security, or to institute suit for the enforcement of any
such payment on or after such respective dates, shall not be impaired or affected without the
consent of such Holder.

43

 

          SECTION 5.8. Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default

          Except as provided in Section 5.6, no right or remedy herein conferred upon or reserved to the
Trustee or to the Securityholders 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.

          No delay or omission of the Trustee or of any Securityholder to exercise any right or power
accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such
right or power or shall be construed to be a waiver of any such Event of Default or an acquiescence
therein; and, subject to Section 5.6, every power and remedy given by this Indenture or by law to
the Trustee or to the Securityholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Securityholders.

          SECTION 5.9. Control by Securityholders

          The Holders of a majority in aggregate principal amount of the Securities of each series
affected (with each series voting as a separate class) at the time Outstanding 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 by this Indenture; provided that such direction shall not be otherwise than in
accordance with law and the provisions of this Indenture and provided, further that the Trustee may
take any other action deemed proper by the Trustee which is not inconsistent with such direction.

          SECTION 5.10. Waiver of Past Defaults

          The Holders of a majority in aggregate principal amount of the Securities of such series at
the time Outstanding may on behalf of the Holders of all the Securities of such series waive any
past default or Event of Default described in clause (g) of Section 5.1 or, in the case of an event
specified in clause (c) of Section 5.1 (if the Event of Default under clause (c) relates to less
than all series of Securities then Outstanding), the Holders of a majority in aggregate principal
amount of the Securities of each series then Outstanding affected thereby (each series voting as a
separate class) may waive any such default or Event of Default, or, in the case of an event
specified in clause (c) (if the Event of Default under clause (c) relates to all series of
Securities then Outstanding), (d), (e) or (f) of Section 5.1, the Holders of Securities of a
majority in principal amount of all the Securities then Outstanding (voting as one class) may waive
any such default or Event of Default and its consequences except a default in respect of a covenant
or provision hereof which cannot be modified or amended without the consent of the Holder of each
Security affected. In the case of any such waiver, the Company, the Trustee and

44

 

the Holders of the Securities of such series shall be restored to their former positions and
rights hereunder, respectively, and such default shall cease to exist and be deemed to have been
cured and not to have occurred, and any Event of Default arising therefrom shall be deemed to have
been cured, and not to have occurred for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any right consequent
thereon.

          SECTION 5.11. Trustee to Give Notice of Default, But May Withhold in Certain
Circumstances

          The Trustee shall transmit to the Securityholders of any series, as the names and addresses of
such Holders appear on the registry books, notice by mail of all defaults which have occurred with
respect to such series to the knowledge of a Responsible Officer of the Trustee, such notice to be
transmitted within 90 days after the occurrence thereof, unless such defaults shall have been cured
before the giving of such notice (the term “default” or “defaults” for the purposes of this Section
being hereby defined to mean any event or condition which is, or with notice or lapse of time or
both would become, an Event of Default); provided that, except in the case of default in the
payment of the principal of or interest or any amount payable pursuant to Section 3.1(b) upon any
of the 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
trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding
of such notice is in the interests of the Securityholders of such series.

          SECTION 5.12. Undertaking to Pay Costs

          All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by such party
litigants but the provisions of this Section 5.12 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of Securityholders of any series
holding in the aggregate more than 10% in aggregate principal amount of the Securities of such
series, or, in the case of any suit relating to or arising under clause (c) of Section 5.1 (if the
suit relates to Securities of more than one but less than all series), 10% in aggregate principal
amount of Securities Outstanding affected thereby, or in the case of any suit relating to or
arising under clause (c) (if the suit under clause (c) relates to all the Securities then
Outstanding), (d), (e) or (f) of Section 5.1, 10% in aggregate principal amount of all Securities
Outstanding, or to any suit instituted by any Securityholder for the enforcement of the payment of
the principal of or interest (including additional amounts payable under Section 3.1(b)), if any,
on any Security on or after the due date expressed in such Security.

ARTICLE SIX

THE TRUSTEE

          SECTION 6.1. Certain Duties and Responsibilities

          The provisions of this Section 6.1 are in furtherance of and subject to the Trust Indenture
Act.

          (a) Except during the continuance of an Event of Default:

          (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 be under
a duty to examine the same to determine whether or not they conform to the requirements of
this Indenture (but need not confirm or investigate the accuracy of mathematical
calculations or other facts stated therein).

          (b) In case an Event of 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 person would exercise or use under the circumstances in the
conduct of such person’s own affairs.

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

          (1) this Subsection shall not be construed to limit the effect of Subsection (b) of
this Section 6.1;

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

          (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 a majority in
principal amount of the Outstanding Securities relating to the time, method and place of
conducting any proceeding for any

46

 

remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under this Indenture; and

          (4) no provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it.

          (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 6.1.

          SECTION 6.2. Notice of Defaults

          The Trustee shall give the Holders notice of any default hereunder as and to the extent
provided by the Trust Indenture Act; provided, however, that in the case of any
default of the character specified in Section 5.1(c), no such notice to Holders shall be given
until at least 30 days after the occurrence thereof. For the purpose of this Section, the term
“default” means any event which is, or after notice or lapse of time or both would become, an Event
of Default.

          SECTION 6.3. Certain Rights of the Trustee

          Subject to the provisions of the Trust Indenture Act:

          (a) the Trustee may conclusively rely and shall be protected in acting or refraining from
acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or
document believed by it to be genuine and to have been signed or presented by the proper party or
parties;

          (b) any request or direction of the Company mentioned herein shall be sufficiently evidenced
by an Officers’ Certificate and any resolution of the Board of Directors of the Company may be
sufficiently evidenced by a Board Resolution;

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

          (d) the Trustee may consult with counsel of its selection and the written advice of such
counsel or any Opinion of Counsel shall be full and complete

47

 

authorization and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon;

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

          (f) the Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction,
consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or investigation into such facts
or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney (at the sole cost of the Company) and shall incur no liability
or additional liability of any kind by reason of such inquiry or investigation;

          (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties
hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed with
due care by it hereunder;

          (h) the Trustee shall not be required to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the exercise of any of
its rights or powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably assured to it;

          (i) the Trustee shall not be liable for any action taken, suffered, or omitted to be taken by
it in good faith and reasonably believed by it to be authorized or within the discretion or rights
or powers conferred upon it by this Indenture;

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

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

48

 

          (l) the Trustee may request that the Company deliver an Officers’ Certificate setting forth
the names of individuals and/or titles of officers authorized at such time to take specified
actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person
authorized to sign an Officers’ Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.

          SECTION 6.4. Trustee Not Responsible for Recitals or Issuance of Securities

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

          SECTION 6.5. May Hold Securities

          The Trustee, any paying agent, any Security Registrar or any other agent of the Company, in
its individual or any other capacity, may become the owner or pledgee of Securities and may
otherwise deal with the Company with the same rights it would have if it were not Trustee, paying
agent, Security Registrar or such other agent.

          SECTION 6.6. Money Held in Trust

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

          SECTION 6.7. Compensation and Reimbursement.

          The Company agrees:

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

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

49

 

or advance as shall have been caused by its own negligence or willful misconduct; and

          (3) to indemnify the Trustee and any predecessor Trustee and their agents for, and to
hold them harmless against, any loss, liability, claim, damage or expense incurred,
including taxes (other than taxes based on the income of the Trustee), without negligence
or willful misconduct on its part, arising out of or in connection with the acceptance or
administration of the trust or trusts hereunder, including the reasonable costs and
expenses of defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder.

          The obligations of the Company under this Section 6.7 to compensate the Trustee and to pay or
reimburse the Trustee for expenses, disbursements and advances shall constitute additional
indebtedness hereunder. Such additional indebtedness shall have a prior lien to that of the
Securities upon all property and funds held or collected by the Trustee as such, except funds held
in trust to pay principal of or interest or additional amounts pursuant to Section 3.1(b) on
particular Securities.

          If the Trustee incurs expenses or renders services after the occurrence of an Event of Default
specified in Section 5.1(d) or (e), the expenses and the compensation for the services will be
intended to constitute expenses of administration under any bankruptcy law. The Company’s
obligations under this Section 6.7 and any lien arising hereunder shall survive the resignation or
removal or any Trustee, the discharge of the Company’s obligations pursuant to Article Ten and the
termination of this Indenture.

          SECTION 6.8. Disqualification; Conflicting Interests

          If the Trustee has or shall acquire a conflicting interest with 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 6.9. Corporate Trustee Required; Eligibility

          There shall at all times be a Trustee hereunder which shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has combined capital and surplus of at least
$50,000,000 and has its Corporate Trust Office or a principal office in the City of New York, or
any other major city in the United States that is acceptable to the Company. If such Person
publishes reports of condition at least annually, pursuant to law or to the requirements of any
Federal or State supervising or examining authority, then for the purposes of this Section 6.9, the
combined capital and surplus of such Person shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. If at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section 6.9, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article Six.

50

 

          SECTION 6.10. Resignation and Removal; Appointment of Successor

          (a) No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article Six shall become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements of Section 6.11.

          (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 6.11 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series.

          (c) The Trustee may be removed at any time with respect to the Securities of any series by an
Act of the Securityholders of a majority in principal amount of the Outstanding Securities of such
series, delivered to the Trustee and to the Company and the Trustee may then petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of
such series..

          (d) If at any time:

          (1) the Trustee shall fail to comply with Section 6.8 after written request therefor
by the Company or by any Securityholder 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 6.9 and shall fail to resign
after written request therefor by the Company or by any such Securityholder 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, or

          (4) the Trustee shall commence a voluntary proceeding under any applicable Federal or
State bankruptcy, insolvency, delinquency or similar law or shall consent to the
appointment of or taking possession by a receiver, custodian, rehabilitator, liquidator,
assignee, trustee, sequestrator (or other similar official) of the Trustee or its property
or affairs, or shall make an assignment for the benefit of creditors, or shall admit in
writing its inability to pay its debts generally as they become due, or shall take
corporate action in furtherance of any such action.

51

 

               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 5.12, any Securityholder who has been a bona
fide Securityholder 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 6.11. If, within one year
after such resignation, removal or incapability, or the occurrence of such vacancy, a successor
Trustee with respect to the Securities of any series shall be appointed by an act of the
Securityholders of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the applicable requirements of
Section 6.11, become the successor Trustee with respect to the Securities of such series and to
that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the Company or the
Securityholders and accepted appointment in the manner required by Section 6.11, any Securityholder
who has been a bona fide Securityholder 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 in the manner provided in Section 1.5. 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 6.11. 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 transferring to such successor Trustee all the rights, powers and trusts of the retiring

52

 

Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder, subject to its liens, if any, provided for in
Section 6.7.

          (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities
of one or more 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) 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, as the case may
be.

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

          SECTION 6.12. 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

53

 

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 Six, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation
to such authenticating Trustee may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself authenticated such
Securities.

          SECTION 6.13. Preferential Collection of Claims against Company

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

          SECTION 6.14. Appointment of Authenticating Agent

          The Trustee may at any time appoint an authenticating agent (“Authenticating Agent”) or agents
with respect to one or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series upon original issue, or issued upon exchange,
registration of transfer or partial redemption thereof or in lieu of destroyed, lost or stolen
Securities, and Securities so authenticated shall be entitled to the benefits of this Indenture and
shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder.
Wherever reference is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation or
national banking association organized and doing business and in good standing under the laws of
the United States of America, any State thereof or the District of Columbia, authorized under such
laws to act as Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State or District of Columbia
authorities. If such Authenticating Agent publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be
deemed to be its combined capital and surplus as set forth in its most recent report of condition
so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, such Authenticating Agent shall resign immediately in the manner
and with the effect specified in this Section.

          Any corporation or national banking association into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation or national banking
association resulting from any merger, conversion

54

 

or consolidation to which such Authenticating Agent shall be a party, or any corporation or
national banking association succeeding to the corporate agency or corporate trust business of an
Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation or
national banking association shall be otherwise eligible under this Section, without the execution
or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give
notice thereof to the Holders of Securities in the manner and to the extent provided in Section
1.6. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

          The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section.

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

55

 

CERTIFICATION OF AUTHENTICATION

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

	 	 	 	 	 	 	 	 	 
	 

	 	 	 	 	 	 	 	 
	 	 	 	 	THE BANK OF NEW YORK	 	 
	 	 	 	 	as Trustee	 	 
	 
	 	 	 	 	 	 	 	 
	Dated:

	 	 	 	By: 	 	 	 	 
	 

	 	 
	 	 	 
    	 	 
	 	 	 	 	as Authenticating Agent	 	 
	 
	 	 	 	 	 	 	 	 
	 

	 	 	 	By: 	 	 	 	 
	 

	 	 	 	 	 	 	 
	 	 	 	 	as Authenticating Agent	 	 

          If all of the Securities of a series may not be originally issued at one time, and if the
Trustee does not have an office capable of authenticating Securities upon original issuance located
in a Place of Payment where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested by the Company in writing (which writing need not
comply with Section 1.2 and need not be accompanied by an Opinion of Counsel), shall appoint in
accordance with this Section an Authenticating Agent having an office in a Place of Payment
designated by the Company with respect to such series of Securities.

          SECTION 6.15. Trustee’s Application for Instructions from the Company

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

56

 

ARTICLE SEVEN

CONCERNING THE SECURITYHOLDERS

          SECTION 7.1. Securities Owned by Company Deemed Not Outstanding

          In determining whether the holders of the requisite aggregate principal amount of Outstanding
Securities of any or all series have concurred in any request, demand, authorization, direction,
notice, consent, waiver or other action by Securityholders under this Indenture, Securities which
are owned by the Company or any other obligor on the Securities with respect to which such
determination is being made or by any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company or any other obligor on the Securities
with respect to which such determination is being made shall be disregarded and deemed not to be
Outstanding for the purpose of any such determination, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such action only Securities which the
Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been
pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction
of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee
is not the Company or any other obligor upon the Securities or any person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Company or any
other obligor on the Securities. In case of a dispute as to such right, the advice of counsel
shall be full protection in respect of any decision made by the Trustee in accordance with such
advice. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an
Officers’ Certificate listing and identifying all Securities, if any, known by the Company to be
owned or held by or for the account of the Company or any other obligor on the Securities; and,
subject to Sections 6.1 and 6.3, the Trustee shall be entitled to accept such Officers’ Certificate
as conclusive evidence of the facts therein set forth and of the fact that all Securities not
listed therein are Outstanding for the purpose of any such determination.

          SECTION 7.2. Rights of Revocation of Action Taken

          At any time prior to (but not after) the evidencing to the Trustee, as provided in Section
1.4(a), of the taking of any action by the Holders of the percentage in aggregate principal amount
of the Securities of any or all series, as the case may be, specified in this Indenture in
connection with such action, any holder of a Security the serial number or other distinguishing
symbol of which is shown by the evidence to be included among serial numbers or other
distinguishing symbols of the Securities the Holders of which have consented to such action may, by
filing written notice at the Corporate Trust Office and upon proof of holding as provided in this
Article, revoke such action so far as concerns such Security. Except as aforesaid any such action
taken by the Holder of any Security shall be conclusive and binding upon such Holder and upon all
future Holders and owners of such Security and of any Securities issued in exchange or

57

 

substitution therefor or on registration of transfer thereof, irrespective of whether or not
any notation in regard thereto is made upon any such Security. Any action taken by the Holders of
the percentage in aggregate principal amount of the Securities of any or all series, as the case
may be, specified in this Indenture in connection with such action shall be conclusively binding
upon the Company, the Trustee and the Holders of all the Securities affected by such action.

ARTICLE EIGHT

SUPPLEMENTAL INDENTURES

          SECTION 8.1. Supplemental Indentures Without Consent of Securityholders

          The Company, when authorized by a Board Resolution, and the Trustee may from time to time and
at any time enter into an indenture or indentures supplemental hereto (which shall conform to the
provisions of the Trust Indenture Act) for one or more of the following purposes:

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

          (b) to add another corporation as the guarantor of the Company’s obligations herein and under
the Securities, to add to the covenants of the Company for the benefit of the Holders of all or any
series of Securities (and if such covenants are to be for the benefit of less than all series of
Securities, stating that such covenants are expressly being included solely for the benefit of such
series) or to surrender any right or power herein conferred upon the Company; or

          (c) to add any additional Events of Default with respect to all or any series of Securities;
or

          (d) to add to or change any of the provisions of this Indenture to such extent as shall be
necessary to permit or facilitate the issuance of Securities in bearer form, registrable or not
registrable as to principal, and with or without interest coupons or to provide for uncertificated
(commonly known as “book-entry”) Securities in each case on terms satisfactory in form and
substance to the Trustee; or

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

          (f) to secure the Securities; or

58

 

          (g) to establish the form or terms of Securities of any series as permitted by Sections 2.1
and 2.4; or

          (h) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee
with respect to the Securities of one or more series and to add to or change any of the provisions
of this Indenture as shall be necessary to provide for or facilitate the administration of the
trusts hereunder by more than one Trustee, pursuant to the requirements of Section 6.11(b); or

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

          (j) to comply with any requirement of the Commission in connection with the qualification of
this Indenture under the Trust Indenture Act.

          The Trustee is hereby authorized to join with the Company in the execution of any such
supplemental indenture, to make any further appropriate agreements and stipulations which may be
therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any
property thereunder.

          Any supplemental indenture authorized by the provisions of this Section may be executed
without the consent of the Holders of any of the Securities at the time Outstanding,
notwithstanding any of the provisions of Section 8.2.

          SECTION 8.2. Supplemental Indentures with Consent of Securityholder

          Subject to Section 8.1 and the first paragraph of Section 2.4, with the consent (evidenced as
provided in Article Seven) of the Holders of not less than a majority in aggregate principal amount
of the Securities at the time Outstanding of all series affected by such supplemental indenture
(voting as one class), the Company, when authorized by a Board Resolution, and the Trustee may,
from time to time and at any time, enter into an indenture or indentures supplemental hereto (which
shall conform to the provisions of the Trust Indenture Act) for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner the rights of the Holders of the
Securities of each such series; provided, that no such supplemental indenture shall (a) change the
final maturity of any Security, or reduce the principal amount thereof, or reduce the rate or
change the time of payment of interest, if any, thereon, or reduce any amount payable on redemption
thereof or reduce the amount of the principal of any Original Issue Discount Security that would be
due and payable upon an acceleration of the maturity thereof pursuant to Section 5.1 or the amount
thereof provable in bankruptcy pursuant to Section 5.2, or impair or affect the right of any
Securityholder to institute suit

59

 

for the payment thereof or, if the Securities provide therefor, any right of repayment at the
option of the Securityholder without the consent of the Holder of each Security so affected or (b)
reduce the aforesaid percentage of Securities of any series, the consent of the Holders of which is
required for any such supplemental indenture, without the consent of the Holders of each Security
so affected.

          Upon the request of the Company, accompanied by a Board Resolution authorizing the execution
of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent
of Securityholders as aforesaid and other documents, if any, required by Section 1.4(a), the
Trustee shall join with the Company in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture
or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

          It shall not be necessary for the consent of the Securityholders under this Section 8.2, to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

          Promptly after the execution by the Company and the Trustee of any supplemental indenture
pursuant to the provisions of this Section 8.2, the Company shall mail a notice thereof by first
class mail to the Holders of Securities of each series affected thereby at their addresses as they
shall appear on the Security Register, setting forth in general terms the substance of such
supplemental indenture. Any failure of the Company to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such supplemental indenture.

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

          SECTION 8.3. Effect of Supplemental Indenture

          Upon the execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and be deemed to be modified and amended in accordance therewith and the
respective rights, limitations of rights, obligations, duties and immunities under this Indenture
of the Trustee, the Company and the Holders of Securities of each series affected thereby shall
thereafter be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture for any and all
purposes.

          SECTION 8.4. Execution of Supplemental Indentures

          In executing, or accepting the additional trusts created by, any supplemental indenture
permitted by this Article or the modification thereby of the trusts created by this Indenture, the
Trustee shall be provided with, and shall be fully protected in relying upon, an Opinion of Counsel
stating that the execution of such supplemental indenture is authorized or permitted by this
Indenture and that all conditions precedent to the execution of the supplemental indenture have
been performed. 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 8.5. Notation on Securities in Respect of Supplemental Indentures

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

CONSOLIDATION, MERGER, SALE OR CONVEYANCE

          SECTION 9.1. Company May Consolidate, etc., on Certain Terms

          (a) Subject to the provisions of Section 9.1(b), nothing contained in this Indenture or in any
of the Securities shall prevent any amalgamation, reconstruction, consolidation or merger of the
Company with or into any other corporation or corporations (whether or not affiliated with the
Company), or successive amalgamations, reconstructions, consolidations or mergers in which the
Company or its successor or successors shall be a party or parties, or shall prevent any sale,
conveyance, transfer or lease of the property of the Company as an entirety or substantially as an
entirety, to any other corporation authorized to acquire and operate the same or shall prevent the
assumption of the Company’s obligations hereunder and under all Securities Outstanding;
provided, however, that (i) immediately after giving effect to such transaction, no
Event of Default shall have occurred and be continuing; and (ii) the Company hereby covenants and
agrees that, upon any such amalgamation, reconstruction, consolidation, merger, sale, conveyance,
transfer, lease (other than by way of a temporary lease in the ordinary course of business) or
assumption, (a) the due and punctual payment of the principal of and interest, if any, on all of
the Securities and all other amounts payable on the Securities of a series pursuant to the terms of
this Indenture, according to their tenor, and the due and

61

 

punctual performance and observance of all of the covenants and conditions of this Indenture
to be performed by the Company, shall be expressly assumed, by supplemental indenture satisfactory
in form to the Trustee, executed and delivered to the Trustee by the corporation formed by such
amalgamation, reconstruction, consolidation, or into which the Company shall have been merged, or
by the corporation which shall have acquired such property or assumed such obligations; and (b) any
corporation formed by such amalgamation, reconstruction or consolidation or into which the Company
shall have been merged or which shall have acquired such property or assumed such obligations shall
in such supplemental indenture, agree that any amounts to be paid by the Company in respect of the
Securities shall be paid without deduction or withholding for any and all present and future taxes,
levies, imposts or other governmental charges whatsoever imposed, assessed, levied or collected by
or for the account of the jurisdiction where such corporation is incorporated or any political
subdivision or taxing authority thereof or therein or, if deduction or withholding of any such
taxes, levies, imposts or other governmental charges shall at any time be required by such
jurisdiction or any such subdivision or authority, such corporation will (subject to compliance by
the Holders or beneficial owners of such Securities with any relevant administrative requirements)
pay such additional amounts in respect of principal, premium, if any, interest, if any, and sinking
fund payments, if any, as may be necessary in order that the net amounts paid to the Holders of the
Securities or the Trustee under this Indenture, as the case may be, after such deduction or
withholding, shall equal the respective amounts of principal, premium, if any, interest, if any,
and sinking fund payments, if any, as specified in the Securities to which such Holders or the
Trustee is entitled; provided, however, that the foregoing shall not apply to (i)
any present or future taxes, levies, imposts or other governmental charges which would not have
been so imposed, assessed, levied or collected but for the fact that the Holder or beneficial owner
of the relevant Security is or has been a domiciliary, national or resident of, or engaging or
having been engaged in business or maintaining or having maintained a permanent establishment or
being or having been physically present in, such jurisdiction or such political subdivision or
otherwise having or having had some connection with such jurisdiction or such political subdivision
other than the holding or ownership of a Security, or the collection of principal of, premium, if
any, and interest, if any, on, or the enforcement of, a Security, (ii) any present or future taxes,
levies, imposts or other governmental charges which would not have been so imposed, assessed,
levied or collected but for the fact that, where presentation is required, the relevant Security
was presented more than thirty days after the date such payment became due or was provided for,
whichever is later, (iii) any present or future taxes, levies, imposts or other governmental
charges which are payable otherwise than by deduction or withholding from payments on or in respect
of the relevant Security, (iv) any present or future taxes, levies, imposts or other governmental
charges which would not have been so imposed, assessed, levied or collected but for (A) the failure
to comply with any certification, identification or other reporting requirements concerning the
nationality, residence, identity or connection with such jurisdiction or any political subdivision
or authority thereof by the Holder or beneficial owner of such Security or (B) the failure to make
any declaration or other similar claim or to satisfy any information or reporting requirement,
which, in the case of (A) or (B), is required or imposed by statute, treaty, regulation or

62

 

administrative practice of the United Kingdom or any jurisdiction or such political
subdivision or taxation authority thereof as a precondition to exemption from all or part of such
taxes, levies, imposts or other governmental charges (v) any deduction or withholding that is
payable as a result of or pursuant to any European Union Directive on the taxation of savings
implementing the conclusions of the ECOFIN Council Meeting of 26-27 November 2000 or any law
implementing or complying with, or introduced in order to conform to, such Directive, (vi) any
present or future taxes, levies, imposts or other governmental charges that the Holder would have
been able to avoid by presenting such Security to another paying agent, (vii) any present or future
taxes, levies, imposts or other governmental charges (A) that would not have been so imposed,
assessed, levied or collected if the beneficial owner of the relevant Security had been the Holder
of such Security or (B) that, if the beneficial owner of such Security held the Security as the
Holder of such Security, would have been excluded pursuant to clauses (i) through (vi) inclusive
above, or (viii) any estate, inheritance, gift, sale, transfer, personal property or similar tax,
assessment or other governmental charge or (ix) any combination of the foregoing clauses (i)
through (viii).

          (b) The provisions of Section 9.1(a) do not apply to any sale, conveyance, transfer or lease
of the property of the Company (whether in whole or in part) to any wholly owned direct or indirect
subsidiary of the Company.

          SECTION 9.2. Successor Corporation to be Substituted for Company

          In case of any such amalgamation, reconstruction, consolidation, merger, sale, conveyance
(other than by way of a temporary lease in the ordinary course of business) or assumption and upon
the assumption by the successor corporation, by supplemental indenture, executed and delivered to
the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the
principal of and interest on all of the Securities, and all other amounts payable on the
Securities of a series pursuant to the terms of this Indenture, and the due and punctual
performance of all of the covenants and conditions of this Indenture to be performed by the
Company, such successor corporation shall succeed to and be substituted for the Company, with the
same effect as if it had been named herein as the party of the first part and, thereafter, except
in the case of a lease, the Company shall be relieved of all obligations and covenants under this
Indenture and the Securities. Such successor corporation thereupon may cause to be signed in its
own name any or all of the Securities issuable hereunder which heretofore shall not have been
signed by the Company and delivered to the Trustee, and, upon the Company Order of such successor
corporation instead of the Company and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities which
previously shall have been signed and delivered by the officers of the Company to the Trustee for
authentication, and any Securities which such successor corporation thereafter shall cause to be
signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all
respects have the same legal rank and benefit under this Indenture as the Securities theretofore or
thereafter issued in accordance with the terms of this Indenture as though all of such Securities
had been issued at the date of the execution hereof.

63

 

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

          SECTION 9.3. Trustee to Receive Opinion of Counsel

          The Trustee, subject to the provisions of Section 6.1, shall receive upon request an Opinion
of Counsel, prepared in accordance with Section 1.2, as conclusive evidence that any such
amalgamation, reconstruction, consolidation, merger, sale or conveyance and any such assumption
complies with the applicable provisions of this Indenture.

ARTICLE TEN

shall have delivered to the Trustee for cancellation all Outstanding Securities of any series or
(c) (i) all the Securities of such series not theretofore paid or delivered to the Trustee for
cancellation shall have become due and payable, or are by their terms to become due and payable
within one year or are to be called for redemption within one year under arrangements satisfactory

Section 10.4), or Government Obligations, maturing as to principal and interest in such amounts and
at such times as will insure the availability of cash, sufficient to pay at maturity or upon
redemption all Outstanding Securities of such series not theretofore delivered to the Trustee for
cancellation, including principal and interest (including additional amounts payable under Section
3.1(b)), if any, due or to become due to such date of maturity as the case may be, and if, in any
such case, the Company shall also pay or cause to be paid all other sums payable hereunder by the
Company with respect to Securities of such series, then this Indenture shall cease to be of further
effect with respect to Securities of such series (except as to (i) rights of registration of
transfer and exchange, and the Company’s right of optional redemption, (ii) substitution of
mutilated, defaced, destroyed, lost or stolen Securities, (iii) rights of Holders to receive
payments of principal thereof and interest (including additional amounts payable under Section
3.1(b)), if any, thereon upon the original stated due dates therefor (but not upon acceleration),
and remaining rights of the Holders to receive mandatory sinking fund payments, if any, (iv) the
rights, obligations and immunities of the Trustee hereunder and
(v) the rights of the Securityholders of such series as beneficiaries hereof with respect to

cost and expense of the Company, shall execute proper instruments acknowledging such satisfaction
of and discharging this Indenture with respect to such series; provided that the rights of
Holders of the Securities to receive amounts in respect of principal of and interest (including
additional amounts payable under Section 3.1(b)), if any, on the Securities held by them shall not
be delayed longer than required by then applicable mandatory rules or policies of any securities
exchange upon which the Securities are listed. The Company agrees to reimburse the Trustee for any
costs or expenses thereafter reasonably and properly incurred and to compensate the Trustee for any
services thereafter reasonably and properly rendered by the Trustee in connection with this
Indenture or the Securities of such series.

          SECTION 10.2. Application by Trustee of Funds Deposited for Payment of Securities

          Subject to Sections 10.4 and 10.5, all moneys deposited with the Trustee pursuant to Section

agent (including the Company acting as paying agent), to the Holders of the particular Securities
of such series for the payment or redemption of which such moneys have been deposited with the
Trustee, of all sums due and to become due thereon for principal and interest, if any; but such
money need not be segregated from other funds except to the extent required by law.

          SECTION 10.3. Defeasance Upon Deposit of Moneys or Government Obligations

          At the Company’s option, either (a) the Company shall be deemed to have been Discharged (as
defined below) from its obligations with respect to any series of Securities on the 91st day after
the applicable conditions set forth below have been satisfied or (b) the Company shall cease to be
under any obligation to comply with any term, provision or condition set forth in Sections 3.6,
3.7, 9.1 and 9.2 (or any other restrictive covenant added for the benefit of Holders of one or
more series of Securities pursuant to Sections 2.4 or 8.1(b)) and non-compliance with such Sections
shall not give rise to any Event of Default under Section 5.1(c), with respect to any series of
Securities at any time after the applicable conditions set forth below have been satisfied:

          (1) the Company shall have deposited or caused to be deposited irrevocably with the
Trustee or its agent as trust funds in trust, specifically pledged as security for, and
dedicated solely to, the benefit of the holders of the Securities of such series (i) money
in an amount, or (ii) Government Obligations of the United States which through the payment
of interest thereon and principal thereof in accordance with their terms will provide, not
later than the due date of any payment, money in an amount, or (iii) a combination of (i)
and (ii), sufficient, in the opinion (with respect to (ii) and (iii))
of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge each

65

 

installment of principal (including mandatory sinking fund payments) of, and interest
(including additional amounts payable under Section 3.1(b)) on, the outstanding Securities
of such series on the dates such installments of interest or principal are due or to and
including the redemption date irrevocably designated by the Company pursuant to
subparagraph (4) hereof;

          (2) no Event of Default or event which with notice or lapse of time would become an
Event of Default under Section 5.1(d) or (e) with respect to the Securities of such series
shall have occurred and be continuing on the date of such deposit;

          (3) in the case of the Securities of such series being discharged pursuant to clause
(a) only, the Company shall have delivered to the Trustee either (i) an Opinion of Counsel
to the effect that holders of the Securities of such series will not recognize income, gain
or loss for Federal income tax purposes as a result of the exercise of the option under
clause (a) above and will be subject to Federal income tax on the same amounts and in the
same manner and at the same times as would have been the case if such option had not been
exercised, or (ii) a ruling to that effect received from or published by the United States
Internal Revenue Service; and

          (4) if the Company has deposited or caused to be deposited money or Government
Obligations to pay or discharge the principal of and interest on the Outstanding Securities
of a series to and including a redemption date pursuant to subparagraph (1) hereof, such
redemption date shall be irrevocably designated by a Board Resolution delivered to the
Trustee on or prior to the date of deposit of such money or Government Obligations and such
Board Resolution shall be accompanied by an irrevocable Company Order that the Trustee give
notice of such redemption in the name and at the expense of the Company not less than
thirty nor more than sixty days prior to such redemption date in accordance with Section
11.4.

          “Discharged” means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by, and obligations under, the Securities of such series and to have
satisfied all the obligations under this Indenture relating to the Securities of such series (and
the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the
sale), except (A) the rights of holders of Securities of such series to receive, from the trust
fund described in clause (1) above, payment of the principal of and the interest (including
additional amounts payable pursuant to Section 3.1(b)) on such Securities when such payments are
due; (B) the Company’s obligations, as the case may be, with respect to such Securities under
Sections 2.9, 2.10, 3.2, 3.4 and 6.7; and (C) the rights, powers, trusts, duties and immunities of
the Trustee hereunder.

          In connection with the satisfaction and discharge of this Indenture with respect to Securities
of any series, all moneys then held by any paying agent under the provisions of this Indenture with
respect to such series of Securities shall, upon demand of the Company, be repaid to the Company or
paid to the Trustee and thereupon such paying agent shall be released from all further liability
with respect to such moneys.

          SECTION 10.5. Return of Moneys Held by Trustee and Paying Agent Unclaimed for Two
Years

          Any moneys deposited with or paid to the Trustee or any paying agent for the payment of the
principal of or interest (including additional amounts payable pursuant to Section 3.1(b)), if any,
on any Security of any series and not applied but remaining unclaimed for two years after the date
upon which such principal or interest shall have become due and payable, shall, upon the written
request of the Company and unless otherwise required by mandatory provisions of applicable escheat
or abandoned or unclaimed property law, be repaid to the Company by the Trustee for such series or
such paying agent, and the Holder of the Security of such series shall, unless otherwise required
by mandatory provisions of applicable escheat or abandoned or unclaimed property laws, thereafter
look only to the Company for any payment which such Holder may be entitled to collect, and all
liability of the Trustee or any paying agent with respect to such moneys shall thereupon cease.
The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the Government Obligations deposited pursuant to Section 10.3 or the principal and
interest received in respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of Outstanding Securities.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES AND SINKING FUNDS

          SECTION 11.1. Applicability of Article

          The provisions of this Article shall be applicable to the Securities of any series which are
redeemable before their maturity and to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.4 for Securities of such series.

          SECTION 11.2. Election to Redeem; Notice to Trustee

          The election of the Company to redeem any Securities shall be evidenced by a Board Resolution.
In case of any redemption at the election of the Company of all or less than all of the Securities
of any series, the Company shall, at least 60 days prior to the date fixed for redemption by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such date and of the principal
amount of Securities of such series to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption provided in the

67

 

terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers’ Certificate evidencing compliance with such restriction.

          SECTION 11.3. Selection by Trustee of Securities to be Redeemed

          Except as otherwise specified as contemplated by Section 2.3 for Securities of any series, if
less than all the Securities of any series with the same terms are to be redeemed, the particular
Securities to be redeemed shall be selected, not more than 60 days prior to the applicable date
fixed for redemption, by the Trustee, from the Outstanding Securities of such series not previously
called for redemption, by such method as the Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to the minimum authorized denomination
for Securities of that series or any integral multiple thereof) of the principal amount of
Securities of such series of a denomination larger than the minimum authorized denomination for
Securities of that series.

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

          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 11.4. Notice of Redemption

          Notice of redemption to the Holders of Securities of any series to be redeemed as a whole or
in part at the option of the Company shall be given by mailing notice of such redemption by
first-class mail, postage prepaid, at least thirty days and not more than sixty days prior to the
date fixed for redemption to such Holders of Securities of such series at their last addresses as
they shall appear on the Security Register. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not the Holder receives
the notice. Failure to give notice by mail, or any defect in the notice to the Holder of any
Security of a series designated for redemption as a whole or in part shall not affect the validity
of the proceedings for the redemption of any other Security of such series.

          The notice of redemption to each such Holder shall specify the CUSIP number (if any) and the
principal amount of each Security of such series held by such Holder to be redeemed, the date fixed
for redemption, the redemption price, the place or places of payment, that payment will be made
upon presentation and surrender of such Securities, that such redemption is pursuant to the
mandatory or optional sinking fund, or both, if such be the case, that interest accrued to the date
fixed for redemption will be
paid as specified in such notice and that on and after said date interest thereon or on the
portions thereof to be redeemed will cease to accrue. In case any Security of a series is to

68

 

be
redeemed in part only, the notice of redemption shall state the portion of the principal amount
thereof to be redeemed and shall state that on and after the date fixed for redemption, upon
surrender of such Security, a new Security or Securities of such series, in principal amount equal
to the unredeemed portion thereof, will be issued.

          The notice of redemption of Securities of any series to be redeemed at the option of the
Company shall be given by the Company or, at the Company’s timely request, by the Trustee in the
name and at the expense of the Company.

          At least one Business Day prior to the redemption date specified in the notice of redemption
given as provided in this Section, the Company will deposit with the Trustee or with one or more
paying agents (or, if the Company is acting as paying agent, set aside, segregate and hold in trust
as provided in Section 3.4) an amount of money sufficient to redeem on the redemption date all the
Securities of such series so called for redemption at the appropriate redemption price, together
with accrued interest and additional amounts payable under Section 3.1(b), if any, to the date
fixed for redemption.

          SECTION 11.5. Payment of Securities Called for Redemption

          If notice of redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and at the place
stated in such notice at the applicable redemption price, together with interest accrued to the
date fixed for redemption, and on and after said date (unless the Company shall default in the
payment of such Securities at the redemption price, together with interest, if any, accrued to said
date) any interest on the Securities or portions of Securities so called for redemption shall cease
to accrue and, except as provided in Sections 6.6 and 10.5, such Securities shall cease from and
after the date fixed for redemption to be entitled to any benefit or security under this Indenture,
and the Holders thereof shall have no right in respect of such Securities except the right to
receive the redemption price thereof and unpaid interest to the date fixed for redemption. On
presentation and surrender of such Securities at a Place of Payment specified in said notice, said
Securities or the specified portions thereof shall be paid and redeemed by the Company at the
applicable redemption price, together with any interest (including additional amounts payable under
Section 3.1(b)) accrued thereon to the date fixed for redemption; provided that any
semiannual payment of interest becoming due on the date fixed for redemption shall be payable to
the Holders of such Securities registered as such in the Security Register on the relevant record
date subject to the terms and provisions of Section 2.8

          If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal shall, until paid or duly provided for, bear interest from the date fixed
for redemption at the rate of interest or Yield to Maturity (in the case of an Original Issue
Discount Security) borne by the Security.

          Upon presentation of any Security redeemed in part only, the Company shall execute and the
Trustee shall authenticate and deliver to or on the order of the

69

 

Holder thereof, at the expense of
the Company, a new Security or Securities of such series, of authorized denominations, in principal
amount equal to the unredeemed portion of the Security so presented.

          SECTION 11.6. Exclusion of Certain Securities from Eligibility for Selection for
Redemption

          Securities shall be excluded from eligibility for selection for redemption if they are
identified by registration and certificate number or other distinguishing symbol in a written
statement signed by an authorized officer of the Company and delivered to the Trustee at least
forty days prior to the last date on which notice of redemption may be given 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 as directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company.

          SECTION 11.7. Mandatory and Optional Sinking Funds

          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”. The date on which a sinking fund payment is to be made is
herein referred to as the “sinking fund payment date”.

          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 2.11, (b) receive credit
for optional sinking fund payments (not previously so credited) made pursuant to this Section, 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.

          On or before the sixtieth day next preceding each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officers’ Certificate (which need not
contain the statements required by Section 1.2) (a) specifying the portion of the mandatory sinking
fund payment to be satisfied by payment of cash and the portion to be satisfied by credit of
Securities of such series, (b) stating that none of the Securities of such series has theretofore
been so credited, (c) stating that no defaults in
the payment of interest (including additional amounts payable under Section 3.1(b)), if any,
or Events of Default with respect to such series have occurred (which have not been

waived or
cured) and are continuing, and (d) stating whether or not the Company intends to exercise its right
to make an optional sinking fund payment with respect to such series and, if so, specifying the
amount of such optional sinking fund payment which the Company intends to pay on or before the next
succeeding sinking fund payment date. Any Securities of such series to be credited and required to
be delivered to the Trustee in order for the Company to be entitled to credit therefor as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for cancellation
pursuant to Section 2.11 to the Trustee with such Officers’ Certificate (or reasonably promptly
thereafter if acceptable to the Trustee). Such Officers’ Certificate 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 sixtieth day, to deliver such
Officers’ Certificate 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 thereof and (ii) that the Company will make no optional sinking fund payment
with respect to such series as provided in this Section.

          If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on
the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund
payments made in cash shall exceed $50,000 (or a lesser sum if the Company shall so request) with
respect to the Securities of any particular series, such cash shall be applied on the next
succeeding sinking fund payment date to the redemption of Securities of such series at the sinking
fund redemption price together with accrued interest to the date fixed for redemption. If such
amount shall be $50,000 or less and the Company makes no such request then it shall be carried over
until a sum in excess of $50,000 is available. The Trustee shall select, in the manner provided in
Sections 11.3 and 11.6, for redemption on such sinking fund payment date a sufficient principal
amount of Securities of such series to absorb said cash, as nearly as may be, and shall (if
requested in writing by the Company) inform the Company of the serial numbers or other
distinguishing symbols of the Securities of such series (or portions thereof) so selected. The
Trustee, in the name and at the expense of the Company (or the Company, if it shall so request the
Trustee in writing) shall cause notice of redemption of the Securities of such series to be given
in substantially the manner provided in Section 11.3 (and with the effect provided in Section 11.5)
for the redemption of Securities of such series in part at the option of the Company. The amount
of any sinking fund payments not so applied or allocated to the redemption of Securities of such
series shall be added to the next cash sinking fund payment for such series and, together with such
payment, shall be applied in accordance with the provisions of this Section. Any and all sinking
fund moneys held on the stated maturity date of the Securities of any particular series (or
earlier, if such maturity is accelerated), which are not held for the payment or redemption
of particular Securities of such series shall be applied, together with other moneys, if
necessary, sufficient for the purpose, to the payment of the principal of and interest

71

 

(including
additional amounts payable under Section 3.1(b)), if any, on the Securities of such series at
maturity.

          At least one Business Day before each sinking fund payment date, the Company shall pay to the
Trustee in cash or shall otherwise provide for the payment of, all interest (including additional
amounts payable under Section 3.1(b)), if any, accrued to the date fixed for redemption on
Securities to be redeemed on the next following sinking fund payment date.

          The Trustee shall not redeem or cause to be redeemed any Securities 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 or of any Event of Default
on such Securities 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 Securities of such series. In case such Event of Default
shall have been waived as provided in Section 5.10 or the default cured on or before the sixtieth
day preceding the sinking fund payment date in any year, such moneys shall thereafter be applied on
the next succeeding sinking fund payment date in accordance with this Section to the redemption of
such Securities.

          SECTION 11.8. Optional Redemption or Assumption Due to Changes in Tax Treatment

          (a) Unless otherwise specified with respect to the Securities of any series, if as the result
of any change in or any amendment to the laws, including any applicable double taxation treaty or
convention, of the United Kingdom (or the jurisdiction where a successor corporation to the Company
pursuant to Section 9.1 is incorporated), or of any political subdivision or taxing authority
thereof or therein affecting taxation, or any change in an application or interpretation of such
laws, including any applicable double taxation treaty or convention, which change, amendment,
application or interpretation becomes effective on or after the original issuance date of the
Securities of such series (or, if such change or amendment is with respect to tax imposed with
respect to payments from the jurisdiction in which a successor corporation to the Company pursuant
to Section 9.1 is incorporated, such later date on which such successor corporation becomes a
successor corporation), it is determined by the Company that (i) the Company would be required,
pursuant to Section 3.1(b), to make additional payments in respect of principal, premium, if any,
interest (including additional amounts payable under Section 3.1(b)), if any, or sinking fund
payments, if any, on the next succeeding date for the payment thereof, or (ii) any tax
would be imposed (whether by way of deduction, withholding or otherwise) by the United Kingdom
(or the jurisdiction of incorporation of a successor corporation to the

72

 

Company pursuant to Section
9.2) or by any political subdivision or taxing authority thereof or therein) upon or with respect
to any principal, premium, if any, interest, if any, or sinking fund payments, if any, received or
receivable by the Company from any of its Subsidiaries incorporated in, or resident for tax
purposes under the laws of, the United Kingdom (or the jurisdiction of incorporation of a successor
corporation to the Company pursuant to Section 9.2) or (iii) based upon an opinion of independent
counsel to the Company, as a result of any action taken by any taxing authority of, or any action
brought in a court of competent jurisdiction in, the United Kingdom (or the jurisdiction where a
successor corporation to the Company pursuant to Section 9.1 is incorporated), or any political
subdivision thereof, which action is taken or brought on or after the original issuance date of the
Securities of such series (or, if such action is with respect to tax imposed with respect to
payments from the jurisdiction in which a successor corporation to the Company pursuant to Section
9.1 is incorporated, such later date on which such successor corporation becomes a successor
corporation), the circumstances described in clauses (i) or (ii) would exist, the Company may, at
its option, redeem such series of Securities in whole at any time (except in the case of Securities
of a series having a variable rate of interest, which may be redeemed on any Interest Payment Date)
at a redemption price equal to 100 percent of the principal amount thereof plus accrued interest
(including additional amounts payable under Section 3.1(b)) to the date fixed for redemption
(except in the case of Outstanding Original Issue Discount Securities which may be redeemed at the
redemption price specified by the terms of each series of such Securities).

          (b) Prior to any redemption of a series of Securities pursuant to paragraph (a) above, the
Company shall provide the Trustee with an Opinion of Counsel that the conditions precedent to the
right of the Company to redeem such Securities pursuant to this Section have occurred. Such
Opinion of Counsel shall be based on the laws in effect on the date of such opinion or to become
effective on or before the next succeeding date of payment of principal, interest or a sinking fund
payment.

          SECTION 11.9. Optional Redemption

          The Securities shall be subject to redemption at the option of the Company, in whole or in
part, at any time prior to maturity at the Company’s option, at a redemption price equal to the
greater of : (i) 100% of the principal amount of the Securities to be redeemed, or (ii) the sum of
the present values of the remaining scheduled payments of principal and interest (including
additional amounts payable under Section 3.1(b)) on the Securities to be redeemed (not including
any payments of interest accrued as of the date fixed for redemption) discounted to such redemption
date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Adjusted Treasury Rate (as defined below), plus 25 basis points, as calculated by an Independent
Investment Banker (as defined below), plus, in each case, accrued and unpaid interest (including
additional amounts payable under Section 3.1(b)) on the Securities to be redeemed to the date fixed
for redemption.

73

 

          For the purposes of this Section 11.9, the following terms shall have the meanings indicated:

          The term “Adjusted Treasury Rate” means with respect to any redemption date:

          (a) the yield, under the heading which represents the average for the immediately preceding
week appearing in the most recently published statistical release designated “H.15(519)” or any
successor publication which is published weekly by the Board of Governors of the Federal Reserve
System and which establishes yields on actively traded US Treasury securities adjusted to constant
maturity under the caption “Treasury Constant Maturities” for the maturity corresponding to the
Comparable Treasury Issue (as defined below). If no maturity is within three months before or
after the Remaining Life, yields for the two published maturities most closely corresponding to the
Comparable Treasury Issue will be determined and the Adjusted Treasury Rate will be interpolated or
extrapolated from those yields on a straight line basis, routing to the nearest month; or

          (b) if the statistical release described in the previous paragraph (or any successor release)
is not published during the week preceding the calculation date or does not contain the relevant
yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable
Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for
that redemption date.

          The Adjusted Treasury Rate will be calculated on the third business day preceding the
redemption date.

          The term “Comparable Treasury Issue” means the US Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term of the
Securities to be redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Securities to be redeemed (the “remaining life”).

          The term “Comparable Treasury Price” means (1) the average of five Reference Treasury
Dealer Quotations (as defined below) for the redemption date, after excluding the highest and
lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains
fewer than five Reference Treasury Dealer Quotations, the average of all such quotations.

          The term “Independent Investment Banker” means an independent investment and banking
institution of international standing appointed by the Company.

          The term “Reference Treasury Dealer” means at least two primary US government
securities dealers in New York City selected by the Company.

74

 

          The term “Reference Treasury Dealer Quotations” means with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the Independent Investment
Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00
p.m., New York City time, on the third business day preceding the redemption date.
