     SECTION 104. Form of Documents Delivered to Trustee.

     In any case where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified by, or covered by
the opinion of, only one such Person, or that they be so certified or covered by only one document,
but one such Person may certify or give an opinion with respect to some matters and one or more
other such Persons as to other matters, and any such Person may certify or give an opinion as to

provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing. Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments or record or both are delivered to the Trustee and,
where it is hereby expressly required, to the Company. Such instrument or instruments and any such
record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as
the “Act” of the Holders signing such instrument or instruments and so voting at any such meeting.
Proof of execution of any such instrument or of a writing appointing any such agent, or the holding
of any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in
this Section 105. The record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 1306.

     The Company may set a record date for purposes of determining the identity of Holders of
Securities entitled to vote or consent to any action by vote or consent authorized or permitted
under this Indenture. If a record date is fixed, those Persons who were Holders of Outstanding
Securities at such record date (or their duly designated proxies), and only those Persons, shall be
entitled with respect to such Securities to take such action by vote or consent or to revoke any
vote or consent previously given, whether or not such Persons continue to be Holders after such
record date. Promptly after any record date is set pursuant to this paragraph, the Company, at its
own expense,

7

 

shall cause notice thereof to be given to the Trustee in writing in the manner provided in
Section 106 and to the relevant Holders as set forth in Section 107.

     (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 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.

     (d) In determining whether the Holders of the requisite principal amount of Securities have
given any request, demand, authorization, direction, notice, consent or waiver under this
Indenture, the principal amount of an Original Issue Discount Security that may be counted in
making such determination and that shall be deemed to be Outstanding for such purposes shall be
equal to the amount of the principal thereof that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 502 at the time the taking of such action
by the Holders of such requisite principal amount is evidenced to the Trustee for such Securities.

     (e) 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. Any consent
or waiver of the Holder of any Security shall be irrevocable for a period of six months after the
date of execution thereof, but otherwise any such Holder or subsequent Holder may revoke the
request, demand, authorization, direction, notice, consent or other Act as to his Security or
portion of his Security; provided, however, that such revocation shall be effective only if the
Trustee receives the notice of revocation before the date the Act becomes effective.

     SECTION 106. 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 made, given, furnished or filed in writing to or with the Trustee
at its Corporate Trust Office, Attention: Corporate Trust Administration, or
	 
	 	(2)	 	the Company by the Trustee or by any Holder shall be sufficient for every
purpose hereunder (unless otherwise herein expressly provided) if in writing and
mailed, first-class postage prepaid, to the Company addressed to it at the address of
its principal office specified in the first paragraph of this Indenture or at any other
address previously furnished in writing to the Trustee by the Company, Attention:
Corporate Secretary.

     SECTION 107. Notice to Holders; Waiver.

     Where this Indenture provides for notice to Holders of Securities of any event, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at the address of such Holder
as it appears in the Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice.

     In case by reason of the suspension of regular mail service, or by reason of any other cause
it shall be impracticable to give such notice to Holders of Securities by mail, then such
notification as shall be made with the

8

 

approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In
any case in which notice to Holders of Securities is given by mail, neither the failure to mail
such notice, nor any defect in any notice so mailed, to any particular Holder of a Security, shall
affect the sufficiency of such notice with respect to other Holders of Securities.

     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 108. Conflict With Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any provision of the Trust
Indenture Act or another provision hereof required to be included in this Indenture by any of the
provisions of the Trust Indenture Act, such provision of the Trust Indenture Act shall control. If
any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that
may be so modified or excluded, the former provision shall be deemed to apply to this Indenture as
so modified or to be excluded.

     SECTION 109. 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 110. Successors and Assigns.

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

     SECTION 111. Separability Clause.

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

     SECTION 112. Benefits of Indenture.

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

     SECTION 113. Governing Law.

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

     SECTION 114. Legal Holidays.

     In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any
Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities) payment of principal of, premium (if any) and
interest on or any Additional Amounts with respect to Securities of any series need not be made at
such Place of Payment on such date, but may be made on the next succeeding Business Day at such
Place of Payment with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity, provided that no interest shall accrue with respect to
such payment for the period from and after such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be.

respect to the Company’s obligations on the Securities or the obligations of the Company or the
Trustee under this Indenture or any certificate or other writing delivered in connection herewith.

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

     EACH OF THE COMPANY AND THE TRUSTEE HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY

Section 303 for the authentication and delivery of such Securities (or any such temporary global

as Trustee

 	 
	 	By:  	 	 
	 	 	Authorized Signatory” 	 
	 	 	 	 
	 

     SECTION 203. Securities in Global Form.

     If Securities of a series are issuable in global form, as contemplated by Section 301, then,
notwithstanding clause (10) of Section 301 and the provisions of Section 302, any such Security
shall represent such of the Outstanding Securities of such series as shall be specified therein and
may provide that it shall represent the aggregate amount of Outstanding Securities from time to
time endorsed thereon and that the aggregate amount of Outstanding Securities represented thereby
may from time to time be reduced to reflect exchanges or redemptions. Any endorsement of a Security
in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding
Securities represented thereby shall be made by the Trustee in such manner and upon instructions
given by such Person or Persons as shall be specified in such Security or in a Company Order to be
delivered to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions of
Section 303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any Security
in permanent global form in the manner and upon instructions given by the Person or Persons
specified in such Security or in the applicable Company Order. With respect to the Securities of
any series that are represented by a Security in global form, the Company authorizes the execution
and delivery by the Trustee of a letter of representations or other similar agreement or instrument
in the form customarily provided for by the Depositary appointed with respect to such global
Security. Any Security in global form may be deposited with the Depositary or its nominee, or may
remain in the custody of the Security Custodian therefor pursuant to an agreement between the
Trustee and the Depositary. If a Company Order pursuant to Section 303 or 304 has been, or
simultaneously is, delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Security in global form shall be in writing but need not comply with
Section 103 and need not be accompanied by an Opinion of Counsel.

     Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under
this Indenture with respect to any Security issued in global form held on their behalf by the
Depositary, or the Security Custodian as its custodian, or under such global Security, and the
Depositary may be treated by the Company, the Security Custodian and any agent of the Company or
the Trustee as the absolute owner of such global Security for all purposes whatsoever.
Notwithstanding the foregoing, (i) the registered holder of a Security of any series issued in
global form may grant proxies and otherwise authorize any Person, including Agent Members and
Persons that may hold interests through Agent Members, to take any action that a Holder of such
series is entitled to take under this Indenture or the Securities of such series and (ii) nothing
herein shall prevent the Company, the Security Custodian or any agent of the Company or the
Security Custodian, from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the
operation of customary practices governing the exercise of the rights of a beneficial owner of any
Security.

     Notwithstanding Section 305, except as otherwise specified as contemplated by Section 301, any
permanent global Security shall be exchangeable only as provided in this paragraph. If the
beneficial owners of interests in a permanent global Security are entitled to exchange such
interest for Securities of such series and of like tenor and principal amount of another authorized
form and denomination, as specified as contemplated by Section 301, then without unnecessary delay
but in any event not later than the earliest date on which such interests may be so exchanged, the
Company shall deliver to the Trustee definitive Securities of that series in an aggregate principal
amount equal to the principal amount of such permanent global Security, executed by the Company. On
or after the earliest date on which such interests may be so exchanged, such permanent global
Security shall be surrendered from time to time in accordance with instructions given to the
Trustee and the Depositary (which instructions shall be in writing but need not comply with Section
103 or be accompanied by an Opinion of Counsel) by the Depositary or such other depositary as shall
be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for
such purpose, to be exchanged, in whole or in part, for definitive Securities of the same series
without charge and the Trustee shall authenticate and deliver, in exchange for each portion of such
permanent global Security, a like aggregate principal amount of other definitive Securities of the
same series of authorized denominations and of like tenor as the portion of such permanent global
Security to be exchanged; provided, however, that no such exchanges may occur during a period
beginning at the opening of business 15 days before any selection of Securities of that series is
to be redeemed and ending on the relevant Redemption Date.

11

 

     Promptly following any such exchange in part, such permanent global Security marked to
evidence the partial exchange shall be returned by the Trustee to the Depositary or such other
depositary referred to above in accordance with the instructions of the Company referred to above.
If a definitive Security is issued in exchange for any portion of a permanent global Security after
the close of business at the office or agency where such exchange occurs on (i) any Regular Record
Date and before the opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such office or agency
on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as
the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as
the case may be, in respect of such Security, but will be payable on such Interest Payment Date or
proposed for payment, as the case may be, only to the Person to whom interest in respect of such
portion of such permanent global Security is payable in accordance with the provisions of this
Indenture.

     Notwithstanding Section 305, except as otherwise specified as contemplated by Section 301,
transfers of a Security issued in global form shall be limited to transfers of such global Security
in whole, but not in part, to the Depositary, its successors or their respective nominees.
Interests of beneficial owners in a Security issued in global form may be transferred in accordance
with the rules and procedures of the Depositary. Securities of any series shall be transferred to
all beneficial owners of a global Security of such series in exchange for their beneficial
interests in that global Security if, and only if, either (1) the Depositary notifies the Company
that it is unwilling or unable to continue as Depositary for the global Security of such series or
at any time the Depositary ceases to be registered under the Exchange Act, (2) an Event of Default,
or an event which, with notice or the lapse of time or both, would constitute an Event of Default,
has occurred with respect to such series and is continuing and the Security Registrar has received
a request from the Depositary or the Trustee to issue Securities of such series in lieu of all or a
portion of that global Security (in which case the Company shall deliver Securities of such series
within 30 days of such request) or (3) the Company determines in its sole discretion that a global
Security shall be exchangeable for definitive Securities in registered form.

     In connection with any transfer of a portion of the beneficial interest in a global Security
of any series to beneficial owners pursuant to this Section 203, the Security Registrar shall
reflect on its books and records the date and a decrease in the principal amount of the global
Security of that series in an amount equal to the principal amount of the beneficial interest in
the global Security of that series to be transferred, and the Company shall execute, and the
Trustee upon receipt of a Company Order for the authentication and delivery of Securities of that
series shall authenticate and deliver, one or more Securities of the same series of like tenor and
amount.

     In connection with the transfer of all the beneficial interests in a global Security of any
series to beneficial owners pursuant to this Section 203, the global Security shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall
authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the global Security, an equal aggregate principal amount of Securities of
that series of authorized denominations.

     Neither the Company nor the Trustee will have any responsibility or liability for any aspect
of the records relating to, or payments made on account of, Securities of any series by the
Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to
such Securities. Neither the Company nor the Trustee shall be liable for any delay by the related
global Security Holder or the Depositary in identifying the beneficial owners, and each such Person
may conclusively rely on, and shall be protected in relying on, instructions from such global
Security Holder or the Depositary for all purposes (including with respect to the registration and
delivery, and the respective principal amounts, of the Securities to be issued).

     The provisions of the last sentence of Section 303 shall apply to any Security in global form
if such Security was never issued and sold by the Company and the Company delivers to the Trustee
the Security in global form together with written instructions (which need not comply with Section
103 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the
principal amount of Securities represented thereby, together with the written statement
contemplated by the last sentence of Section 303.

     Notwithstanding the provisions of Sections 201 and 307, unless otherwise specified as
contemplated by Section 301, payment of principal of, premium (if any) and interest on or any
Additional Amounts with respect to any Security in permanent global form shall be made to the
Person or Persons specified therein.

12

 

     Notwithstanding the provisions of Section 308 and except as provided in the preceding
paragraph, the Company, the Trustee and any agent of the Company or of the Trustee shall treat a
Person as the Holder of such principal amount of Outstanding Securities represented by a global
Security as shall be specified in a written statement, if any, of the Holder of such global
Security which is produced to the Security Registrar by such Holder.

     Global Securities may be issued in either temporary or permanent form. Permanent global
Securities will be issued in definitive form.

	 	(20)	 	any other terms of such series.

     All Securities of any one series shall be substantially identical except as to denomination
and except as may otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’
Certificate referred to above or in any such indenture supplemental hereto.

     At the option of the Company, interest on the Securities of any series that bears interest may
be paid by mailing a check to the address of any Holder as such address shall appear in the
Security Register.

     If any of the terms of the series are established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action together with such Board Resolution
shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the
Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the
series.

     SECTION 302. Denominations.

     The Securities of each series shall be issuable in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such provisions with respect to the Securities
of any series, the Securities of such series denominated in Dollars shall be issuable in
denominations of $1,000 and any integral multiple thereof. Unless otherwise provided as
contemplated by Section 301 with respect to any series of Securities, any Securities of a series
denominated in a currency other than Dollars shall be issuable in denominations that are the
equivalent, as determined by the Company by reference to the noon buying rate in The City of New
York for cable transfers for such currency (“Exchange Rate”), as such rate is reported or otherwise
made available by the Federal Reserve Bank of New York, on the applicable issue date for such
Securities, of $1,000 and any integral multiple thereof.

     SECTION 303. Execution, Authentication, Delivery and Dating.

     The Securities shall be executed on behalf of the Company by a director, its Chairman of the
Board, its Chief Executive Officer, its President, its Treasurer or one of its Vice Presidents. The
signature of any of these persons on the Securities may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities of any series executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and delivery of such
Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver
such Securities as in this Indenture provided and not otherwise.

     If the form or terms of the Securities of a series have been established in or pursuant to one
or more Board Resolutions or any other method permitted by Sections 201 and 301, in authenticating
such Securities, and accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating that,

	 	(a)	 	the form of such Securities has been established in conformity with the
provisions of this Indenture;
	 
	 	(b)	 	the terms of such Securities have been established in conformity with the
provisions of this Indenture; and
	 
	 	(c)	 	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 legal,

15

 

	 	 	 	valid and binding obligations of the Company, enforceable in accordance with their
terms, except as such enforcement is subject to the effect of (i) bankruptcy,
insolvency, fraudulent conveyance, reorganization or other laws relating to or
affecting creditors’ rights and (ii) general principles of equity (regardless of
whether such enforcement is considered in a proceeding in equity or at law).

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

     Each Security shall be dated the date of its authentication.

     No Security shall be entitled to any benefit under this Indenture or be valid or obligatory
for any purpose unless there appears on such Security a certificate of authentication substantially
in the form provided for herein executed by the Trustee by manual signature, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the Company, and the
Company shall deliver such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 103 and need not be
accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by
the Company, for all purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the benefits of this
Indenture.

     SECTION 304. Temporary Securities.

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

     Except in the case of temporary Securities in global form (which shall be exchanged in
accordance with the provisions of the following paragraphs), if temporary Securities of any series
are issued, the Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of the Company in a
Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Securities of any series, the Company shall execute and deliver a Company
Order requesting the Trustee to authenticate and deliver and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of the same series of
authorized denominations. Until so exchanged the temporary Securities of any series shall in all
respects be entitled to the same benefits under this Indenture as definitive Securities of such
series.

     All Outstanding temporary Securities of any series shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder.

     SECTION 305. Registration, Registration of Transfer and Exchange.

     The Company shall cause to be kept for each series of Securities at one of the offices or
agencies maintained pursuant to Section 1002 a register (the register maintained in such office and
in any other office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the “Security Register”) in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration of Securities and
of transfers of Securities of such series. The Trustee is hereby initially appointed “Security
Registrar” for the purpose of registering Securities and transfers of Securities as herein
provided.

16

 

     Except as set forth in Section 203 or as may be provided pursuant to Section 301, upon
surrender for registration of transfer of any Security of any series at the office or agency in a
Place of Payment for that series, the Company shall execute and deliver a Company Order requesting
the Trustee to authenticate and deliver and the Trustee shall authenticate and deliver, in the name
of the designated transferee or transferees, one or more new Securities of the same series and of
like tenor, of any authorized denominations and of a like aggregate principal amount.

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

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

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

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

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

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

     If any mutilated Security is surrendered to the Trustee, the Company shall execute and deliver
a Company Order requesting the Trustee to authenticate and deliver and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series and of like tenor
and principal amount and bearing a number not contemporaneously outstanding.

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

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

     Upon the issuance of any new Security under this Section 306, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fee and expenses of the Trustee) connected
therewith.

17

 

     Every new Security of any series issued pursuant to this Section 306 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 306 are exclusive and shall preclude (to the extent lawful) all
other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Securities.

     SECTION 307. Payment of Interest; Interest Rights Preserved.

     Interest on any Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular Record Date for such
interest. Unless otherwise provided with respect to the Securities of any series, payment of
interest may be made at the option of the Company by check mailed or delivered to the address of
any Person entitled thereto as such address shall appear in the Security Register.

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

	 	(1)	 	The Company may elect to make payment of any Defaulted Interest to the Persons
in whose names the Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security of such series and the date of the proposed
payment, and at the same time the Company shall deposit with the Trustee an amount of
money equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit prior
to the date of the proposed payment, such money when deposited to be held in trust for
the benefit of the Persons entitled to such Defaulted Interest as in this clause (1)
provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10 days prior
to the date of the proposed payment and not less than 10 days after the receipt by the
Trustee of the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the Company,
shall cause notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder of
Securities of such series at his address as it appears in the Security Register, not
less than 10 days prior to such Special Record Date. The Trustee may, in its
discretion, in the name and at the expense of the Company, cause a similar notice to be
published at least once in an Authorized Newspaper, but such publication shall not be a
condition precedent to the establishment of such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor having
been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the
Securities of such series (or their respective Predecessor Securities) are registered
at the close of business on such Special Record Date and shall no longer be payable
pursuant to the following clause (2).
	 
	 	(2)	 	The Company may make payment of any Defaulted Interest on the Securities of any
series in any other lawful manner not inconsistent with the requirements of any
securities exchange on which such Securities may be listed, and upon such notice as may
be required by such exchange, if, after notice given by the Company to the Trustee of
the proposed payment pursuant to this clause (2), such manner of payment shall be
deemed practicable by the Trustee.

18

 

     Subject to the foregoing provisions of this Section 307, each Security delivered under this
Indenture, upon registration of transfer of, in exchange for or in lieu of, any other Security,
shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Security.

     SECTION 308. Person 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 may treat the Person in whose name such Security is
registered as the owner of such Security for the purpose of receiving payment of principal of,
premium (if any) and (subject to Sections 305 and 307) interest 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 309. Cancellation.

     All Securities surrendered for payment, redemption, registration of transfer or exchange or
for credit against any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee. All Securities so delivered shall be promptly canceled by the
Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section 309, except as expressly permitted by this Indenture. All canceled Securities held
by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures,
unless the Trustee is otherwise directed by a Company Order.

     SECTION 310. Computation of Interest.

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

     SECTION 311. 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 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.

ARTICLE FOUR

SATISFACTION AND DISCHARGE

     SECTION 401. Satisfaction and Discharge of Indenture.

     This Indenture shall upon Company Request cease to be of further effect with respect to
Securities of a series, and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture with respect to Securities
of such series, when

	 	(1)	 	either

	 	(A)	 	all Securities of such series theretofore authenticated and
delivered (other than (i) Securities that have been destroyed, lost or stolen
and that have been replaced or paid as provided in Section 306, and (ii)
Securities for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter

19

 

	 	 	 	repaid to the Company or discharged from such trust, as provided in Section
1003) have been delivered to the Trustee for cancellation;
	 
	 	(B)	 	with respect to all Outstanding Securities of such series not
theretofore delivered to the Trustee for cancellation, the Company has
deposited or caused to be deposited with the Trustee under the terms of an
irrevocable trust agreement in form and substance satisfactory to the Trustee,
as trust funds in trust solely for the benefit of the Holders of Outstanding
Securities for that purpose, money or U.S. Government Obligations maturing as
to principal and interest in such amounts and at such times as will, together
with the income to accrue thereon, without consideration of any reinvestment
thereof, be sufficient to pay and discharge the entire indebtedness on all
Outstanding Securities of such series not theretofore delivered to the Trustee
for cancellation for principal of, premium (if any) and interest on or any
Additional Amounts with respect to such Securities to the Stated Maturity or
any Redemption Date contemplated by the penultimate paragraph of this Section
401, as the case may be; or
	 
	 	(C)	 	the Company has properly fulfilled such other means of
satisfaction and discharge as is specified, as contemplated by Section 301, to
be applicable to the Securities of such series;

	 	(2)	 	the Company has paid or caused to be paid all other sums payable hereunder by
the Company with respect to the Outstanding Securities of such series;
	 
	 	(3)	 	the Company has complied with any other conditions specified pursuant to
Section 301 to be applicable to the discharge of Securities of such series pursuant to
this Section 401;
	 
	 	(4)	 	the Company has delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent herein provided for
relating to the satisfaction and discharge of this Indenture with respect to the
Outstanding Securities of such series have been complied with;
	 
	 	(5)	 	if the conditions set forth in Section 401(1)(A) have not been satisfied, and
unless otherwise specified pursuant to Section 301 for the Securities of such series,
the Company has delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of Securities of such series will not recognize income, gain or loss for United
States federal income tax purposes as a result of such deposit, satisfaction and
discharge and will be subject to United States federal income tax on the same amount
and in the same manner and at the same time as would have been the case if such
deposit, satisfaction and discharge had not occurred; and
	 
	 	(6)	 	no Default or Event of Default with respect to the Securities of such issue
shall have occurred and be continuing on the date of such deposit or, insofar as clause
(5) or (6) of Section 501 is concerned, at any time in the period ending on the 91st
day after the date of such deposit (it being understood that this condition shall not
be deemed satisfied until the expiration of such period).

     For the purposes of this Indenture, “U.S. Government Obligations” means direct noncallable
obligations of, or noncallable obligations the payment of principal of and interest on which is
guaranteed by, the United States of America, or to the payment of which obligations or guarantees
the full faith and credit of the United States of America is pledged, or beneficial interests in a
trust the corpus of which consists exclusively of money or such obligations or a combination
thereof.

     If any Outstanding Securities of such series are to be redeemed prior to their Stated
Maturity, whether pursuant to any optional redemption provisions or in accordance with any
mandatory sinking fund requirement, the trust agreement referred to in subclause (B) of clause (1)
of this Section 401 shall provide therefor and the Company shall make such arrangements as are
satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company.

20

 

     Notwithstanding the satisfaction and discharge of this Indenture with respect to the
Outstanding Securities of such series pursuant to this Section 401, the obligations of the Company
to the Trustee under Section 607, the obligations of the Company to any Authenticating Agent under
Section 614 and, except for a discharge pursuant to subclause (A) of clause (1) of this Section
401, the obligations of the Company under Sections 305, 306, 404, 1001 and 1002 and the obligations
of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

     SECTION 402. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1003, all money deposited with the
Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine,
to the Persons entitled thereto, of the principal of, premium (if any) and interest on or any
Additional Amounts with respect to Securities of such Securities for the payment of which such
money has been deposited with the Trustee.

     SECTION 403. Discharge of Liability on Securities of Any Series.

     If this Section 403 is specified, as contemplated by Section 301, to be applicable to
Securities of any series, the Company shall be deemed to have paid and discharged the entire
indebtedness on all the Outstanding Securities of such series, the obligation of the Company under
this Indenture and the Securities of such series to pay the principal of, premium (if any) and
interest on and any Additional Amounts with respect to Securities of such series shall cease,
terminate and be completely discharged, and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging such satisfaction and discharge, when

	 	(1)	 	the Company has complied with the provisions of Section 401 of this Indenture
(other than any additional conditions specified pursuant to Sections 301 and 401(3) and
except that the Opinion of Counsel referred to in Section 401(5) shall state that it is
based on a ruling by the Internal Revenue Service or other change since the date hereof
under applicable Federal income tax law) with respect to all Outstanding Securities of
such series,
	 
	 	(2)	 	the Company has delivered to the Trustee a Company Request requesting such
satisfaction and discharge,
	 
	 	(3)	 	the Company has complied with any other conditions specified pursuant to
Section 301 to be applicable to the discharge of Securities of such series pursuant to
this Section 403, and
	 
	 	(4)	 	the Company has delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent herein provided for
relating to the discharge of the indebtedness on the Outstanding Securities of such
series have been complied with.

     Upon the satisfaction of the conditions set forth in this Section 403 with respect to all the
Outstanding Securities of any series, the terms and conditions of such series, including the terms
and conditions with respect thereto set forth in this Indenture, shall no longer be binding upon,
or applicable to, the Company; provided that, the Company shall not be discharged from any payment
obligations in respect of Securities of such series which are deemed not to be Outstanding under
clause (iii) of the definition thereof if such obligations continue to be valid obligations of the
Company under applicable law or pursuant to Section 305 or 306.

     SECTION 404. Reinstatement.

     If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations
deposited with respect to Securities of any series in accordance with Section 401 by reason of any
legal proceeding or by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under
this Indenture with respect to the Securities of such series and the Securities of such series
shall be revived and reinstated as though no deposit had occurred pursuant to Section 401 until
such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government

21

 

Obligations in accordance with Section 401; provided, however, that if the Company has made any
payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to
any Securities because of the reinstatement of its obligations, the Company shall be subrogated to
the rights of the Holders of such Securities to receive such payment from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

ARTICLE FIVE

REMEDIES

     SECTION 501. Events of Default.

     “Event of Default,” wherever used herein with respect to Securities of any series, means any
one of the following events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or
order of any court or any order, rule or regulation of any administrative or governmental body),
unless it is either inapplicable to a particular series or it is specifically deleted or modified
in or pursuant to the supplemental indenture or Board Resolution establishing such series of
Securities or in the form of Security for such series:

	 	(1)	 	default in the payment of any interest on or any Additional Amounts with
respect to any Security of that series when such interest or Additional Amounts become
due and payable, and continuance of such default for a period of 30 days; or
	 
	 	(2)	 	default in the payment of the principal of or premium (if any) on any Security
of that series at its Maturity; or
	 
	 	(3)	 	default in the deposit of any mandatory sinking fund payment, when and as due
by the terms of a Security of that series, and continuance of such default for a period
of 60 days; or
	 
	 	(4)	 	default in the performance or breach of any covenant of the Company in this
Indenture (other than a covenant a default in whose performance or whose breach is
elsewhere in this Section 501 specifically dealt with or which has expressly been
included in this Indenture solely for the benefit of one or more series of Securities
other than that series), and continuance of such default or breach for a period of 90
days after there has been given, by registered or certified mail, to the Company by the
Trustee or to the Company and the Trustee by the Holders of at least 25% in principal
amount of all Outstanding Securities a written notice specifying such default or breach
and requiring it to be remedied and stating that such notice is a “Notice of Default”
hereunder; or
	 
	 	(5)	 	the entry by a court having jurisdiction in the premises of (A) a decree or
order for relief in respect of the Company in an involuntary case or proceeding under
any applicable federal or state bankruptcy, insolvency, reorganization or other similar
law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or
approving as properly filed a petition seeking reorganization, arrangement, adjustment
or composition of or in respect of the Company under any applicable federal or state
law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestration
or other similar official of the Company or of any substantial part of its property, or
ordering the winding up or liquidation of its affairs, and the continuance of any such
decree or order for relief or any such other decree or order unstayed and in effect for
a period of 90 consecutive days; or
	 
	 	(6)	 	the commencement by the Company of a voluntary case or proceeding under any
applicable federal or state bankruptcy, insolvency, reorganization or other similar law
or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the
consent by it to the entry of a decree or order for relief in respect of the Company in
an involuntary case or proceeding under any applicable federal or state bankruptcy,
insolvency, reorganization or other similar law or to the commencement of any
bankruptcy or insolvency case or proceeding against it, or the filing by it, of a
petition or answer or consent seeking reorganization or relief under any applicable
federal or state law, or the consent by it to the filing of such petition or to the
appointment of or taking

22

 

	 	 	 	possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or
similar official of the Company or of any substantial part of its property, or the
making by it of an assignment for the benefit of creditors, or the admission by it
in writing of its inability to pay its debts generally as they become due; or
	 
	 	(7)	 	any other Event of Default provided with respect to Securities of that series.

     Notwithstanding the foregoing provisions of this Section 501, if the principal of, premium (if
any) or any interest on or any Additional Amounts with respect to any Security is payable in a
currency or currencies (including a composite currency) other than Dollars and such currency or
currencies are not available to the Company for making payment thereof due to the imposition of
exchange controls or other circumstances beyond the control of the Company (a “Conversion Event”),
the Company will be entitled to satisfy its obligations to Holders of the Securities by making such
payment in Dollars in an amount equal to the Dollar equivalent of the amount payable in such other
currency, as determined by the Company by reference to the Exchange Rate, as such Exchange Rate is
certified for customs purposes by the Federal Reserve Bank of New York on the date of such payment,
or, if such rate is not then available, on the basis of the most recently available Exchange Rate.
Notwithstanding the foregoing provisions of this Section 501, any payment made under such
circumstances in Dollars where the required payment is in a currency other than Dollars will not
constitute an Event of Default under this Indenture.

     Promptly after the occurrence of a Conversion Event with respect to the Securities of any
series, the Company shall give written notice thereof to the Trustee; and the Trustee, promptly
after receipt of such notice, shall give notice thereof in the manner provided in Section 107 to
the Holders of such series. Promptly after the making of any payment in Dollars as a result of a
Conversion Event with respect to the Securities of any series, the Company shall give notice in the
manner provided in Section 107 to the Holders of such series, setting forth the applicable Exchange
Rate and describing the calculation of such payments.

     SECTION 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to any Securities of any series at the time Outstanding
occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25%
in principal amount of the Outstanding Securities of (i) the series affected by such default (in
the case of an Event of Default described in clause (1), (2), (3) or (7) of Section 501 or an Event
of Default described in clause (4) of Section 501 relating to a covenant applicable only to such
series) or (ii) all series of Securities (in the case of an Event of Default described in clause
(4) of Section 501 that is applicable to all series of Securities) may declare the principal amount
(or, if any such Securities are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) and accrued interest on of all of the Securities of the series
affected by such default or all series, as the case may be, to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and upon any such
declaration such amount shall become immediately due and payable. If an Event of Default described
in clause (5) or (6) of Section 501 shall occur, the principal amount of and accrued interest on the Outstanding Securities
of all series ipso facto shall become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder.

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

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

	 	(A)	 	all overdue interest on, and any Additional Amounts with
respect to, all Securities of that series (or of all series, as the case may
be),
	 
	 	(B)	 	the principal of or premium (if any) on any Securities of that
series (or of all series, as the case may be) which have become due otherwise
than by such declaration of acceleration

23

 

	 	 	 	and interest thereon at the rate or rates prescribed therefor in such
Securities (in the case of Original Issue Discount Securities, the
Securities’ Yield to Maturity),

	 	(C)	 	to the extent that payment of such interest is lawful, interest
upon overdue interest and any Additional Amounts at the rate or rates
prescribed therefor in such Securities (in the case of Original Issue Discount
Securities, the Securities’ Yield to Maturity), and
	 
	 	(D)	 	all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and all other amounts due the Trustee under Section 607;
and

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

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

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

     The Company covenants that if

	 	(1)	 	default is made in the payment of any installment of interest on, or any
Additional Amounts with respect to, any Security of any series when such interest or
Additional Amounts shall have become due and payable and such default continues in
excess of any applicable grace period, or
	 
	 	(2)	 	default is made in the payment of the principal of or premium (if any) on any
Security at the Maturity thereof, the Company will, upon demand of the Trustee, pay to
it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal of, premium (if any) and interest on or any
Additional Amounts with respect to such Securities and, to the extent that payment of
such interest shall be legally enforceable, interest on any overdue principal, premium
(if any) and on any overdue interest or Additional Amounts, at the rate or rates
prescribed therefor in such Securities (or in the case of Original Issue Discount
Securities, the Securities’ Yield to Maturity), and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and all other amounts due the Trustee under Section 607.

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

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

     SECTION 504. Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the
Company or any other obligor upon the Securities or the property of the Company or of such other
obligor or their creditors, the Trustee

24

 

(irrespective of whether the principal (or lesser amount in the case of Original Issue Discount
Securities) of the Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for
the payment of overdue principal of, premium (if any), interest on or any Additional Amounts with
respect to such Securities) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

	 	(i)	 	to file and prove a claim for the whole amount of principal (or lesser amount
in the case of Original Issue Discount Securities) (and premium, if any) and interest
and any Additional Amounts owing and unpaid in respect of the Securities and to file
such other papers or documents as may be necessary or advisable to have the claims of
the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and of the Holders
allowed in such judicial proceeding, and
	 
	 	(ii)	 	to collect and receive any monies or other property payable or deliverable on
any such claims and to distribute the same; and any custodian, receiver, assignee,
trustee, liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due the Trustee under Section 607.

     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceedings; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or
similar official.

     SECTION 505. Trustee May Enforce Claims Without Possession of Securities or Coupons.

     All rights of action and claim under this Indenture or the Securities may be prosecuted and
enforced by the Trustee without possession of any of the Securities or the production thereof in
any proceeding relating thereto; any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust; after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any
other amounts due the Trustee under Section 607, any recovery of judgment shall be for the ratable
benefit of the Holders of the Securities in respect of which such judgment has been recovered.

     SECTION 506. Application of Money Collected.

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

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

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

     THIRD: The balance, if any, to the Company.

     To the fullest extent allowed under applicable law, if for the purpose of obtaining judgment
against the Company in any court it is necessary to convert the sum due in respect of the principal
of, premium (if any) or

25

 

interest on or any Additional Amounts with respect to 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 which in accordance with normal banking procedures the
Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on
the Business Day in The City of New York next preceding that on which final judgment is given.
Neither the Company nor the Trustee shall be liable for any shortfall nor shall it benefit from any
windfall in payments to Holders of Securities under this Section 506 caused by a change in exchange
rates between the time the amount of a judgment against it is calculated as above and the time the
Trustee converts the Judgment Currency into the Required Currency to make payments under this
Section 506 to Holders of Securities, but payment of such judgment shall discharge all amounts owed
by the Company on the claim or claims underlying such judgment.

     SECTION 507. Limitation on Suits.

     Subject to Section 508, no Holder of any Security of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

	 	(1)	 	an Event of Default with respect to Securities of such series shall have
occurred and be continuing and such Holder has previously given written notice to the
Trustee of such continuing Event of Default;
	 
	 	(2)	 	the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default in its own name as Trustee hereunder;
	 
	 	(3)	 	such Holder or Holders have offered to the Trustee reasonable indemnity against
the costs, expenses and liabilities to be incurred in compliance with such request;
	 
	 	(4)	 	the Trustee for 60 days after its receipt of such notice, request and offer of
indemnity has failed to institute any such proceeding; and
	 
	 	(5)	 	no direction inconsistent with such written request has been given to the
Trustee during such 60-day period by the Holders of a majority in principal amount of
the Outstanding Securities of that series; it being understood and intended that no one
or more of such Holders shall have any right in any manner whatever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other of such Holders, or to obtain or to seek to obtain priority or preference
over any other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

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

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

     SECTION 509. Restoration of Rights and Remedies.

     If the Trustee or any Holder of any Security has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then and in every such
case, the Company, the Trustee and the Holders shall, subject to any determination in such
proceeding, be restored severally and respectively to their

26

 

former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

     SECTION 510. Rights and Remedies Cumulative.

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

     SECTION 511. Delay or Omission Not Waiver.

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

     SECTION 512. Control by Holders.

     With respect to Securities of any series, the Holders of a majority in principal amount of the
Outstanding Securities of such series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power
conferred on the Trustee, relating to or arising under an Event of Default described in clause (1),
(2), (3) or (7) of Section 501 (or clause (4) of Section 501 with respect to a covenant that is
applicable only to such series), and with respect to all Securities the Holders of a majority in
principal amount of all Outstanding Securities shall have the right to direct the time, method and
place of conducting any remedy available to the Trustee, or exercising any trust or power conferred
on the Trustee, not relating to or arising under such an Event of Default, provided that in each
such case

	 	(1)	 	the Trustee shall have the right to decline to follow any such direction if the
Trustee, being advised by counsel, determines that the action so directed may not
lawfully be taken or would conflict with this Indenture or if the Trustee in good faith
shall, by a Responsible Officer, determine that the proceedings so directed would
involve it in personal liability or be unjustly prejudicial to the Holders not taking
part in such direction, and
	 
	 	(2)	 	the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

     SECTION 513. Waiver of Past Defaults.

     Subject to Sections 508 and 902, the Holders of a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the Securities of such
series waive any past default hereunder with respect to such series and its consequences, and the
Holders of a majority in principal amount of all Outstanding Securities may on behalf of the
Holders of all Securities waive any other past default hereunder and its consequences, except in
each case a default

	 	(1)	 	in the payment of the principal of, premium (if any) or interest on or any
Additional Amounts with respect to any Security, or
	 
	 	(2)	 	in respect of a covenant or provision hereof that under Article Nine cannot be
modified or amended without the consent of the Holder of each Outstanding Security
affected.

27

 

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

     SECTION 514. Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by such party
litigant. The provisions of this Section 514 shall not apply to any suit instituted by the Company,
by the Trustee, by any Holder or group of Holders holding in the aggregate more than 10% in
principal amount of the Outstanding Securities of any series, or by any Holder for the enforcement
of the payment of the principal of, premium (if any) or interest on or any Additional Amounts with
respect to any Security on or after the Stated Maturity or Maturities expressed in such Security
(or, in the case of redemption, on or after the Redemption Date).

     SECTION 515. Waiver of Stay or Extension Laws.

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

of any such certificates or opinions that 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.

     (b) In case an Event of Default has occurred and is continuing with respect to the Securities

Indenture, and use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

for its own negligent action, its own negligent failure to act or its own willful misconduct,

subsection (a) of this Section 601;

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

     SECTION 607. Compensation and Reimbursement.

     The Company agrees

	 	(1)	 	to pay to the Trustee from time to time reasonable compensation for all
services rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust);
	 
	 	(2)	 	except as otherwise expressly provided herein, to reimburse the Trustee upon
its request for all reasonable expenses, disbursements and advances incurred or made by
the Trustee in accordance with any provision of this Indenture (including the
reasonable compensation and the reasonable expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be attributable to
its negligence or bad faith; and
	 
	 	(3)	 	to indemnify each of the Trustee and any predecessor Trustee and its directors,
officers, employees, agents and/or representatives for, and to hold each of them
harmless against, any loss, liability or expense incurred without negligence or bad

administration of the trust or trusts hereunder, including the costs and expenses of
defending itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.

     As security for the performance of the obligations of the Company under this Section 607, the
Trustee shall have a lien prior to the Securities on all property and funds held or collected by
the Trustee as such, except funds held in trust for the payment of principal of, premium (if any)

     Any expenses and compensation for any services rendered by the Trustee after the occurrence of
an Event of Default specified in clause (5) or (6) of Section 501 shall constitute expenses and
compensation for services of administration under all applicable federal or state bankruptcy,
insolvency, reorganization or other similar laws.

     The provisions of this Section 607 and any lien arising hereunder shall survive the
resignation or removal of the Trustee or the discharge of the Company’s obligations under this
Indenture and the termination of this Indenture.

     SECTION 608. Disqualification; Conflicting Interests.

     (a) If the Trustee has or shall acquire any conflicting interest, as defined in this Section
608, with respect to the Securities of any series, it shall, within 90 days after ascertaining that

to the Securities of that series in the manner and with the effect hereinafter specified in this
Article Six.

     (b) In the event that the Trustee shall fail to comply with the provisions of subsection (a)

     (c) For the purposes of this Section 608, the term “conflicting interest” shall have the
meaning specified in Section 310(b) of the Trust Indenture Act and the Trustee shall comply with
Section 310(b) of the Trust Indenture Act; provided, that there shall be excluded from the
operation of Section 310(b)(1) of the Trust Indenture Act with respect to the Securities of any
series any indenture or indentures under which other securities, or certificates of interest or
participation in other securities, of the Company are outstanding, if the requirements for such
exclusion set forth in Section 310(b)(1) of the Trust Indenture Act are met. For purposes of the
preceding sentence, the optional provision permitted by the second sentence of Section 310(b)(9) of
the Trust Indenture Act shall be applicable.

31

 

     SECTION 609. Corporate Trustee Required; Eligibility.

     There shall at all times be a Trustee hereunder which shall be a corporation organized and
doing business under the laws of the United States of America, any State thereof or the District of
Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital
and surplus of at least $50 million and subject to supervision or examination by federal or state
(or the District of Columbia) authority. If such corporation 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 609, the combined capital and surplus of such corporation
shall be deemed to be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee shall cease to be eligible in accordance with
the provisions of this Section 609, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article Six.

     The Indenture shall always have a Trustee who satisfies the requirements of Sections
310(a)(1), 310(a)(2) and 310(a)(5) of the Trust Indenture Act.

     SECTION 610. Resignation and Removal; Appointment of Successor.

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

     (b) The Trustee may resign at any time with respect to the Securities of one or more series by
giving written notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 611 shall not have been delivered to the resigning Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may petition any court
of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities
of such series.

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

     (d) If at any time:

	 	(1)	 	the Trustee shall fail to comply with Section 608(a) after
written request therefor by the Company or by any Holder who has been a bona
fide Holder of a Security for at least six months, or
	 
	 	(2)	 	the Trustee shall cease to be eligible under Section 609 and
shall fail to resign after written request therefor by the Company or by any
such Holder of Securities, or
	 
	 	(3)	 	the Trustee shall become incapable of acting or shall be
adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
property shall be appointed or any public officer shall take charge or control
of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case, (i) the Company by a Board
Resolution may remove the Trustee with respect to all Securities, or (ii)
subject to Section 514, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Securities and the appointment of a
successor Trustee or Trustees.

     (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of such series and
that at any time there shall be only one Trustee with respect to the Securities of any

32

 

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

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

     SECTION 611. Acceptance of Appointment by Successor.

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

     (b) In case of the appointment hereunder of a successor Trustee with respect to the Securities
of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee
with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment and which (1)
shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm that all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring
Trustee and (3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute
such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust
or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other
such Trustee; and upon the execution and delivery of such supplemental indenture, the resignation
or removal of the retiring Trustee shall become effective to the extent provided therein and each
such successor Trustee, without any further act, deed or conveyance, shall become vested with all
the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver
to such successor Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of such successor
Trustee relates.

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

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

33

 

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

     Any corporation into which the Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided
such corporation shall be otherwise qualified and eligible under this Article 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, consolidation or transfer of substantially all the
corporate trust business to such authenticating Trustee may adopt such authentication and deliver
the Securities so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

     SECTION 613. Preferential Collection of Claims Against Company.

     The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any
creditor relationship described in Section 311(b) of the Trust Indenture Act. A Trustee who has
resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the
extent indicated therein.

     SECTION 614. Appointment of Authenticating Agent.

     The Trustee may appoint an Authenticating Agent or Agents that shall be authorized to act on
behalf of the Trustee to authenticate Securities issued upon original issue and upon exchange,
registration of transfer or partial redemption or pursuant to Section 306, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory
for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s
certificate of authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any state thereof or the District of Columbia,
having a combined capital and surplus of not less than $50 million or equivalent amount expressed
in a foreign currency and subject to supervision or examination by federal or state (or the
District of Columbia) authority or authority of such country. 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 614, 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 614, such
Authenticating Agent shall resign immediately in the manner and with the effect specified in this
Section 614.

     Any corporation into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or consolidation to
which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible under this Section 614,
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 614, the Trustee
may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall
mail written notice of such appointment by first-class mail, postage prepaid, to all Holders as
their names and addresses appear in the Security Register. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the provisions of this
Section 614.

34

 

     The Company agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section 614.

     If an appointment is made pursuant to this Section 614, the Securities may have endorsed
thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of
authentication in the following form:

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

	 	 	 	 	 
	 	The Bank of New York Mellon Trust Company, N.A.,

As Trustee

 	 
	 	By:  	 	 
	 	 	     As Authenticating Agent 	 
	 	 	 
	 	By:  	
 	 
	 	 	     Authorized Signatory 	 

     Notwithstanding any provision of this Section 614 to the contrary, if at any time any
Authenticating Agent appointed hereunder with respect to any series of Securities shall not also be
acting as the Security Registrar hereunder with respect to any series of Securities, then, in
addition to all other duties of an Authenticating Agent hereunder, such Authenticating Agent shall
also be obligated: (i) to furnish to the Security Registrar promptly all information necessary to
enable the Security Registrar to maintain at all times an accurate and current Security Register;
and (ii) prior to authenticating any Security denominated in a foreign currency, to ascertain from
the Company the units of such foreign currency that are required to be determined by the Company
pursuant to Section 302.

other provisions of this Indenture cannot be modified or waived without the consent of
the Holder of each Outstanding Security affected thereby, provided, however, that this

Indenture of the Holders of Securities of any other series.

38

 

     It shall not be necessary for any Act of Holders under this Section 902 to approve the
particular form of any proposed supplemental indenture, but it shall be sufficient if such Act

Securities of such series.

ARTICLE TEN

COVENANTS

     SECTION 1001. Payment of Principal, Premium and Interest.

     The Company covenants and agrees for the benefit of the Holders of each series of Securities

Additional Amounts with respect to the Securities of that series in accordance with the terms of
the Securities and this Indenture.

     SECTION 1002. Maintenance of Office or Agency.

     The Company will maintain in the Borough of Manhattan, City of New York, an office or agency
(which may be an office of the Trustee, the Registrar or the Paying Agent) where Securities may be
presented or surrendered for payment, where Securities may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Company in respect of Securities
and this Indenture may be served. Unless otherwise designated by the Company by written notice to

Trustee with the address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust

39

 

Office of the Trustee and the Company hereby appoints the Trustee its agent to receive all
presentations, surrenders, notices and demands.

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

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

     If the Company, any Subsidiary or any of their respective Affiliates shall at any time act as
Paying Agent with respect to any series of Securities, such Paying Agent will, on or before each
due date of the principal of, premium (if any) or interest on or any Additional Amounts with
respect to any of the Securities of that series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal, premium (if any) or interest or any
Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its action or failure so to
act.

     Whenever the Company shall have one or more Paying Agents for any series of Securities, the
Company will, on or before each due date of the principal of, premium (if any) or interest on any
Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal of,
premium (if any) or interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section 1003, that such Paying Agent will:

	 	(1)	 	hold all sums held by it for the payment of the principal of, premium (if any)
or interest on or any Additional Amounts with respect to Securities of that series in
trust for the benefit of the Persons entitled thereto until such sums shall be paid to
such Persons or otherwise disposed of as herein provided;
	 
	 	(2)	 	give the Trustee notice of any default by the Company (or any other obligor
upon the Securities of that series) in the making of any payment of principal of,
premium (if any) or interest on or any Additional Amounts with respect to the
Securities of that series; and
	 
	 	(3)	 	at any time during the continuance of any such default, upon the written
request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such
Paying Agent.

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

     Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, premium (if any) or interest on or any Additional
Amounts with respect to any Security of any series and remaining unclaimed for three years after
such principal of, premium (if any) or interest on or any Additional Amounts with respect to any
Securities have become due and payable shall, unless otherwise required by mandatory provisions of
applicable escheat, or abandoned or unclaimed property law, be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all

40

 

liability of the Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the expense of the
Company cause to be published once, in an Authorized Newspaper in The Borough of Manhattan, The
City of New York and in such other Authorized Newspapers as the Trustee shall deem appropriate,
notice that such money remains unclaimed and that, after a date specified herein, which shall not
be less than 30 days from the date of such publication, any unclaimed balance of such money then
remaining will, unless otherwise required by mandatory provisions of applicable escheat, or
abandoned or unclaimed property law, be repaid to the Company.

     SECTION 1004. Existence.

     Subject to Article Eight, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence.

     SECTION 1005. Statement by Officers as to Default.

     The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of
the Company ending after the date hereof so long as any Security is outstanding hereunder, an
Officers’ Certificate, complying with Section 314(a)(4) of the Trust Indenture Act and stating that
a review of the activities of the Company during such year and of performance under this Indenture
has been made under the supervision of the signers thereof and whether or not to the best of their
knowledge, based upon such review, the Company is in default in the performance, observance or
fulfillment of any of its covenants and other obligations under this Indenture, and if the Company
shall be in default, specifying each such default known to them and the nature and status thereof.
One of the director(s) or officers signing the Officers’ Certificate delivered pursuant to this
Section 1005 shall be the principal executive, financial or accounting officer of the Company.

     For purposes of this Section 1005, such compliance shall be determined without regard to any
period of grace or requirement of notice provided under this Indenture.

     SECTION 1006. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any covenant or condition set
forth in Sections 1001 through 1005, inclusive, or any covenant added for the benefit of any series
of Securities as contemplated by Section 301 (unless otherwise specified pursuant to Section 301)
if before or after the time for such compliance the Holders of a majority in principal amount of
the Outstanding Securities of all series affected by such omission (acting as one class) shall, by
Act of such Holders, either waive such compliance in such instance or generally waive compliance
with such covenant or condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any such covenant or
condition shall remain in full force and effect.

     SECTION 1007. Additional Amounts.

     If the Securities of a series expressly provide for the payment of Additional Amounts, the
Company will pay to the Holder of any Security of such series Additional Amounts as expressly
provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of the
principal of, or premium (if any) or interest on any Security of any series or the net proceeds
received from the sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of Additional Amounts provided for in this Section 1007 to the
extent that, in such context, Additional Amounts are, were or would be payable in respect thereof
pursuant to the provisions of this Section 1007 and express mention of the payment of Additional
Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional
Amounts in those provisions hereof where such express mention is not made.

     If the Securities of a series provide for the payment of Additional Amounts, at least 10 days
prior to the first Interest Payment Date with respect to that series of Securities (or if the
Securities of that series will not bear

41

 

interest prior to Maturity, the first day on which a payment of principal and any premium is made),
and at least 10 days prior to each date of payment of principal and any premium or interest if
there has been any change with respect to the matters set forth in the below-mentioned Officers’
Certificate, the Company shall furnish the Trustee and the Company’s principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers’ Certificate instructing the Trustee and
such Paying Agent or Paying Agents whether such payment of principal of and any premium or interest
on the Securities of that series shall be made to Holders of Securities of that series who are
United States Aliens without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of that series. If any such withholding shall be
required, then such Officers’ Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities and the Company will pay to such Paying
Agent the Additional Amounts required by this Section 1007. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished
pursuant to this Section 1007.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

     SECTION 1101. Applicability of Article.

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

     SECTION 1102. Election to Redeem; Notice to Trustee.

     Unless otherwise provided with respect to the Securities of a series as contemplated by
Section 301, 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 less than all the
Securities of any series, the Company shall, at least five (5) business days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers’ Certificate evidencing
compliance with such restriction.

     SECTION 1103. Selection by Trustee of Securities to be Redeemed.

     If less than all the Securities of any series are to be redeemed, the particular Securities to
be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and that 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 or of
the principal amount of global Securities of such series.

     The Trustee shall promptly notify the Company and the Security Registrar 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.

42

 

     SECTION 1104. Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 107 to each Holder of
Securities to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date.

     All notices of redemption shall state:

	 	(1)	 	the Redemption Date,
	 
	 	(2)	 	the Redemption Price,
	 
	 	(3)	 	if less than all the Outstanding Securities of any series are to be redeemed,
the identification (and, in the case of partial redemption, the principal amounts) of
the particular Securities to be redeemed,
	 
	 	(4)	 	that on the Redemption Date the Redemption Price will become due and payable
upon each such Security to be redeemed and, if applicable, that interest thereon will
cease to accrue on and after said date,
	 
	 	(5)	 	the place or places where such Securities are to be surrendered for payment of
the Redemption Price,
	 
	 	(6)	 	that the redemption is for a sinking fund, if such is the case, and
	 
	 	(7)	 	the “CUSIP” number, if applicable.

     A notice of redemption as contemplated by Section 107 need not identify particular Securities
to be redeemed. Notice of redemption of Securities to be redeemed at the election of the Company
shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the
expense of the Company.

     SECTION 1105. Deposit of Redemption Price.

     On or before 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, and any Additional Amounts with respect to, all the Securities which are to be
redeemed on that date.

     SECTION 1106. Securities Payable on Redemption Date.

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

     If any Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal of and premium (if any) shall, until paid, bear interest from the
Redemption Date at the rate prescribed therefor in the Security or, in the case of Original Issue
Discount Securities, the Securities’ Yield to Maturity.

43

 

     SECTION 1107. Securities Redeemed in Part.

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

     Unless otherwise specified as contemplated by Section 301, the Company and any Affiliate of
the Company may at any time purchase or otherwise acquire Securities in the open market or by
private agreement. Such acquisition shall not operate as or be deemed for any purpose to be a
redemption of the indebtedness represented by such Securities. Any Securities purchased or acquired
by the Company may be delivered to the Trustee and, upon such delivery, the indebtedness
represented thereby shall be deemed to be satisfied. Section 309 shall apply to all Securities so
delivered.

ARTICLE TWELVE

SINKING FUNDS

     SECTION 1201. Applicability of Article.

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

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

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

     SECTION 1203. Redemption of Securities for Sinking Fund.

Indenture is hereby amended in respect of, and applicable to, the Notes and only in respect of, and
applicable to, the Notes as follows:

          (a) by adding thereto the following new definitions in their appropriate alphabetical order:

     “Attributable Indebtedness,” when used with respect to any Sale/Leaseback Transaction,
means, as at the time of determination, the present value (discounted at the rate set forth or
implicit in the terms of the lease included in such transaction) of the total obligations of the
lessee for rental payments (other than amounts required to be paid on account of taxes,
maintenance, repairs, insurance, assessments, utilities, operating and labor costs and other items
that do not constitute payments for property rights) during the remaining term of the lease
included in such Sale/Leaseback Transaction (including any period for which such lease has been
extended). In the case of any lease that is terminable by the lessee upon the payment of a penalty,
such net amount shall be the lesser of the net amount determined assuming termination upon the
first day such lease may be terminated (in which case the net amount shall also include the amount
of the penalty, but no rent shall be considered as required to be paid under such lease subsequent
to the first date upon which it may be so terminated) or the net amount determined assuming no such
termination.

     “Capitalized Lease Obligations” of any Person means the obligations of such Person to
pay rent or other amounts under any lease of (or other arrangement conveying the right to use) real
or personal property, or a combination thereof, which obligations are required to be classified and
accounted for as capital leases on a balance sheet of such Person under generally accepted
accounting principles in the United States, and the amount of such obligations shall be the
capitalized amount thereof determined in accordance with generally accepted accounting principles
in the United States.

     “Consolidated Net Tangible Assets” means the total amount of assets (less applicable

2

 

reserves and other properly deductible items) after deducting (1) all current liabilities
(excluding the amount of those that are by their terms extendable or renewable at the option of the
obligor to a date more than 12 months after the date as of which the amount is being determined and
current maturities of long-term debt) and (2) all goodwill, trade names, trademarks, patents,
unamortized debt discount and expense and other like intangible assets, all as set forth on the
most recent quarterly balance sheet of the Guarantor and its consolidated Subsidiaries and
determined in accordance with generally accepted accounting principles in the United States.

     “Funded Indebtedness” means all Indebtedness (including Indebtedness incurred under
any revolving credit, letter of credit or working capital facility) that by its terms matures on,

date on which such Indebtedness is originally incurred.

     “Guarantor” has the meaning set forth in the preamble.

     “Guarantor Board of Directors” means either the board of directors of the Guarantor or
any duly authorized committee of that board.

     “Indebtedness” of any Person means, without duplication, (i) all indebtedness of such
Person for borrowed money (whether or not the recourse of the lender is to the whole of the assets
of such Person or only to a portion thereof), (ii) all obligations of such Person evidenced by
bonds, debentures, notes or other similar instruments, (iii) all obligations of such Person in
respect of letters of credit or other similar instruments (or reimbursement obligations with
respect thereto), other than standby letters of credit, performance bonds and other obligations
issued by or for the account of such Person in the ordinary course of business, to the extent not
drawn or, to the extent drawn, if such drawing is reimbursed not later than the third Business Day
following demand for reimbursement, (iv) all obligations of such Person to pay the deferred and
unpaid purchase price of property or services, except trade payables and accrued expenses incurred
in the ordinary course of business, (v) all Capitalized Lease Obligations of such Person, (vi) all
Indebtedness of others secured by a Lien on any asset of such Person, whether or not such
Indebtedness is assumed by such Person (provided that if the obligations so secured have not been
assumed in full by such Person or are not otherwise such Person’s legal liability in full, then
such obligations shall be deemed to be in an amount equal to the greater of (a) the lesser of (1)
the full amount of such obligations and (2) the fair market value of such assets, as determined in
good faith by the board of directors of such Person, which determination shall be evidenced by a
resolution of such board of directors, and (b) the amount of obligations as have been assumed by
such Person or that are otherwise such Person’s legal liability), and (vii) all Indebtedness of
others (other than endorsements in the ordinary course of business) guaranteed by such Person to
the extent of such guarantee.

lessor under any conditional sale agreement, Capitalized Lease Obligation or other title retention
agreement relating to such asset.

     “Make-Whole Premium” with respect to any Note (or portion of a Note) to be redeemed
shall be equal to the excess, if any, of:

     (i) the sum of the present values, calculated as of the Redemption Date, of:

          (A) each interest payment that, but for the redemption, would have been payable on the
Note (or its portion) being redeemed on each Interest Payment Date occurring after the
Redemption Date (excluding any accrued interest for the period before the Redemption Date);
and

          (B) the principal amount that, but for the redemption, would have been payable at the
final maturity of the Note (or its portion) being redeemed;

over

     (ii) the principal amount of the Note (or its portion) being redeemed.

     The present values of interest and principal payments referred to in clause (i) above will be
determined in accordance with generally accepted principles of financial analysis. Those present
values will be calculated by discounting the amount of each payment of interest or principal from
the date that each payment would have been payable, but for the redemption, to the Redemption Date
at a discount rate equal to the Treasury Yield plus 50 basis points.

     The Make-Whole Premium will be calculated by an independent investment banking institution of
national standing appointed by the Company, provided that if the Company fails to make such
appointment at least 45 Business Days prior to the Redemption Date, or if the institution so
appointed is unwilling or unable to make the calculation, such calculation will be made by Goldman,

of the Guarantor in respect of which (a) the recourse of the holder of such Indebtedness, whether
direct or indirect and whether contingent or otherwise, is effectively limited to (i) Liens on
specified assets and (ii) in respect of Indebtedness of a Subsidiary of the Guarantor, Liens on
assets of the Subsidiary acquired after the date of original issuance of the Notes, and with
respect to such Indebtedness of the Guarantor or a Subsidiary of the Guarantor, neither the
Guarantor nor any Subsidiary of the Guarantor (other than the issuer of such Indebtedness) provides
any credit support or is otherwise liable or obligated and (b) the occurrence of any event, or the
existence of any condition under any agreement or instrument

4

 

relating to such Indebtedness, shall not at any time have the effect of accelerating, or permitting
the acceleration of, the maturity of any other Indebtedness of the Guarantor or any of its
Subsidiaries or otherwise permitting any such other Indebtedness to be declared due and payable, or
to be required to be prepaid, purchased or redeemed, prior to the stated maturity thereof.

     “Pari Passu Indebtedness” means any Indebtedness of the Guarantor, whether outstanding
on the issue date of the Notes or thereafter created, incurred or assumed, unless, in the case of
any particular Indebtedness, the instrument creating or evidencing the same or pursuant to which
the same is outstanding expressly provides that such Indebtedness shall be subordinated in right of
payment to the Guarantee.

     “Permitted Liens” means (i) Liens existing on the date of original issuance of
the Notes; (ii) Liens on property or assets of, or any shares of stock of, or other equity
interests in, or indebtedness of, any Person existing at the time such Person becomes a Subsidiary

one year after the later of the acquisition, the completion of construction, alteration,
improvement or repair or the commencement of commercial operation thereof, which Indebtedness is
incurred for the purpose of financing all or any part of the purchase price thereof or construction
or improvements thereon; (vii) statutory liens or landlords’, carriers’, warehouseman’s,
mechanics’, suppliers’, materialmen’s, repairmen’s or other like Liens arising in the ordinary
course of business and with respect to amounts not yet delinquent or being contested in good faith
by appropriate proceedings; (viii) Liens on current assets of the Guarantor or any Subsidiary of
the Guarantor securing Indebtedness of the Guarantor or such Subsidiary, respectively; (ix) Liens
on the stock, partnership or other equity interest of the Guarantor or any Subsidiary of the

other mobile offshore drilling unit, or integral portion thereof, owned or leased by the Guarantor
or any Subsidiary of the Guarantor and used for drilling offshore oil and gas wells, which, in the

5

 

opinion of the Guarantor Board of Directors, is of material importance to the business of the
Guarantor and its Subsidiaries taken as a whole, but no such jackup, semisubmersible, drillship,
submersible or other mobile offshore drilling unit, or portion thereof, shall be deemed of material
importance if its net book value (after deducting accumulated depreciation) is less than 2.0% of
Consolidated Net Tangible Assets of the Guarantor and its consolidated Subsidiaries.

     “Sale/Leaseback Transaction” means any arrangement with any Person pursuant to which
the Guarantor or any Subsidiary of the Guarantor leases any Principal Property that has been or is
to be sold or transferred by the Guarantor or the Subsidiary to such Person, other than (i)
temporary leases for a term, including renewals at the option of the lessee, of not more than five
years, (ii) leases between the Guarantor and a Subsidiary of the Guarantor or between Subsidiaries
of the Guarantor, or (iii) leases of Principal Property executed by the time of, or within 12
months after the later of, the acquisition, the completion of construction, alteration, improvement
or repair or the commencement of commercial operation of the Principal Property.

     “Tax Additional Amounts” has the meaning set forth in Section 2.2.

     “Taxing Jurisdiction” has the meaning set forth in Section 2.2.

     “Treasury Yield” means a rate of interest per annum equal to the weekly average yield
to maturity of United States Treasury Notes that have a constant maturity that corresponds to the
remaining terms to maturity of the Notes, calculated to the nearest 1/12th of a year (the
“Remaining Term”). The Treasury Yield will be determined as of the third Business Day
immediately before the applicable Redemption Date.

     The weekly average yields of United States Treasury Notes will be determined by referring to
the most recent statistical release published by the Federal Reserve Bank of New York and
designated “H.15(519) Selected Interest Rates” or any successor release (the “H.15 Statistical
Release”). If the H.15 Statistical Release contains a weekly average yield for United States
Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury
Yield will be equal to that weekly average yield. In all other cases, the Treasury Yield will be
calculated by interpolation, on a straight-line basis, between the weekly average yields on the
United States Treasury Notes that have a constant maturity closest to and greater than the
Remaining Term and the United States Treasury Notes that have a constant maturity closest to and
less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any
weekly average yields as calculated by interpolation will be rounded to the nearest 1/100th of 1%
with any figure of 1/200% or above being rounded upward. If weekly average yields for United States
Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury
Yield will be calculated by interpolation of comparable rates selected by the Independent
Investment Banker.

     “Withholding Tax” has the meaning set forth in Section 2.2.

          (b) for purposes of this First Supplemental Indenture only, by adding the following definitions:

     
“Officers’ Certificate”, when used with respect to the Guarantor, means a certificate signed
by (i) the Chairman of the Board, the Chief Executive Officer, the President or a Vice President,
and (ii) the Treasurer, the Controller, the Secretary or an Assistant Treasurer, Assistant
Controller or Assistant Secretary of the Guarantor, and delivered to the Trustee, which
certificate shall be in compliance with Section 103 hereof.
 

6

 

     “Redemption Price” shall be the price equal to 100% of the principal amount of the
Notes being redeemed plus accrued interest to the Redemption Date (subject to the right of
holders of record on the relevant record date to receive interest due on an interest payment date
that is on or prior to the Redemption Date), plus a Make-Whole Premium, if any is required
to be paid. The Redemption Price will never be less than 100% of the principal amount of the Notes
being redeemed plus accrued interest to the Redemption Date.

     “Subsidiary” means, with respect to the Guarantor at any date, any corporation,
limited liability company, partnership, association or other entity the accounts of which would be
consolidated with those of the Guarantor in the Guarantor’s consolidated financial statements if
such financial statements were prepared in accordance with generally accepted accounting principles
in the United States as of such date, as well as any other corporation, limited liability company,
partnership, association or other entity (i) of which securities or other ownership interests
representing more than 50% of the equity or more than 50% of the ordinary voting power or, in the
case of a partnership, more than 50% of the general partnership interests are, as of such date,
owned, controlled or held, or (ii) that is, as of such date, otherwise controlled, by the Guarantor
or one or more Subsidiaries of the Guarantor.

          2.2 Amendments to Article Three of the Indenture (Tax Additional Amounts). Article
Three is hereby amended in respect of, and applicable to, the Notes and only in respect of, and
applicable to, the Notes by adding the following section as Section 312:

          SECTION 312. Tax Additional Amounts.

     The Company shall pay any amounts due with respect to the payments on the Notes
without deduction or withholding for any and all present and future withholding
taxes, levies, imposts and charges (each, a “Withholding Tax”) imposed by or
for the account of the Cayman Islands or any other jurisdiction in which the Company
is resident for tax purposes or any political subdivision or taxing authority of
such jurisdiction (the “Taxing Jurisdiction”), unless such withholding or
deduction is required by law. If such deduction or withholding is at any time
required, the Company will (subject to compliance by such Holder with any relevant
administrative requirements) pay each Holder additional amounts (“Tax Additional
Amounts”) as will result in such Holder’s receipt of such amounts as it would
have received had no such withholding or deduction been required.

     If the Taxing Jurisdiction requires the Company to deduct or withhold any
Withholding Tax, the Company will (subject to compliance by a Holder with any
relevant administrative requirements) pay such Tax Additional Amounts in respect of
principal amount, Redemption Price and interest (if any) in accordance with the
terms of the Notes and the Indenture; provided, however, that the foregoing shall
not apply to:

     (a) any Withholding Tax that would not be payable or due but for the fact that
(1) the Holder of a Note (or a fiduciary, settlor, beneficiary of, member

7

 

or shareholder of, such Holder, if such Holder is an estate, trust, partnership
or corporation) is a domiciliary, national or resident of, or engaging in business
or maintaining a permanent establishment or being physically present in, the Taxing
Jurisdiction or otherwise having some present or former connection with the Taxing
Jurisdiction other than the holding or ownership of the Note or the collection of
principal amount, Redemption Price and interest (if any), in accordance with the
terms of the Note and the Indenture or the enforcement of the Note or (2) where
presentation is required, the Note was presented more than 30 days after the date
such payment became due or was provided for, whichever is later;

     (b) any Withholding Tax attributable to any estate, inheritance, gift, sales,
transfer, excise, personal property or similar tax, levy, impost or charge;

     (c) any Withholding Tax attributable to any tax, levy, impost or charge that is
payable otherwise than by withholding from payment of principal amount, Redemption
Price and interest (if any);

     (d) any Withholding Tax that would not have been imposed but for the failure to
comply with certification, information, documentation or other reporting
requirements concerning the nationality, residence, identity or connections with the
relevant tax authority of the Holder or beneficial owner of the Senior Note, if this
compliance is required by statute or by regulation as a precondition to relief or
exemption from such Withholding Tax;

     (e) to the extent a Holder of a Note is entitled to a refund or credit in the
Taxing Jurisdiction of amounts required to be withheld by such Taxing Jurisdiction;
or

     (f) any combination of the instances described in (a) through (e).

     With respect to clause (e), above, in the absence of evidence satisfactory to
the Company, the Company may conclusively presume that a Holder of a Note is
entitled to a refund or credit of all amounts required to be withheld. The Company
shall not be required to pay any Tax Additional Amounts to any Holder of a Note who
is a fiduciary or partnership or other than the sole beneficial owner of the Note to
the extent that a beneficiary or settlor with respect to such fiduciary, or a member
of such partnership or a beneficial owner thereof, would not have been entitled to
the payment of such Tax Additional Amounts had such beneficiary, settlor, member or
beneficial owner been the Holder of the Note.

     Tax Additional Amounts
shall be treated as Additional Amounts for purposes of the Indenture.
All references in the Indenture or the Notes to “interest” shall
include (without duplication) any Tax Additional Amounts due with respect thereto.

     2.3 Amendments to Article Seven of the Indenture (Reports by the Company). Article
Seven of the Indenture is hereby amended in respect of, and applicable to, the Notes and only in
respect of, and applicable to, the Notes by amending and restating in its entirety Section 704 as
follows:

8

 

     SECTION 704. Reports by the Company.

     The Company shall file with the Trustee, within 15 days after the Company is
required to file the same with the Commission, copies of the annual reports and of
the information, documents and other reports (or copies of such portions of any of
the foregoing as the Commission may from time to time by rules and regulations
prescribe) that the Company may be required to file with the Commission pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, and
shall otherwise comply with Section 314(a) of the Trust Indenture Act.
Notwithstanding the prior sentence, any obligation of the Company to file reports
with the Trustee pursuant to the prior sentence shall be deemed to be satisfied for
so long as Guarantor (or any other person that is a successor to Guarantor’s
reporting obligations to the Commission) shall file with the Trustee within the time
period provided in the prior sentence copies of the annual reports and of the
information, documents and other reports (or copies of such portions of any of the
foregoing as the Commission may from time to time by rules and regulations
prescribe) that Guarantor (or any other person that is a successor to Guarantor’s
reporting obligations to the Commission) may be required to file with the Commission
pursuant to Section 12 or Section 15(d) of the Securities Exchange Act of 1934, as
amended, and such annual reports, information, documents and other reports contain
such information relating to the Company as is required by the rules and regulations
of the Commission.

     2.4 Amendments to Article Eight of the Indenture (Consolidation, Amalgamation, Conveyance,
Transfer or Lease). Article Eight of the Indenture is hereby amended in respect of, and
applicable to, the Notes and only in respect of, and applicable to, the Notes by adding thereto the
following new Sections 803 and 804:

     SECTION 803. Guarantor May Consolidate, Etc., Only on Certain Terms.

     The Guarantor shall not consolidate or amalgamate with or merge into any other Person or sell,
lease, convey, transfer or otherwise dispose of all or substantially all of its properties and
assets to any Person (other than a direct or indirect Wholly-Owned Subsidiary of the Guarantor),
unless:

	(1)	 	either (a) the Guarantor shall be the continuing Person or (b) the Person formed by such
consolidation or amalgamation or into which the Guarantor is merged, or that acquires, by
sale, lease, conveyance, transfer or other disposition, all or substantially all of the
properties and assets of the Guarantor, shall expressly assume, by a supplemental indenture,
the Guarantee, and the performance of the Guarantor’s covenants and obligations under this
Indenture and the Guarantee;
	 
	(2)	 	immediately after giving effect to such transaction, and treating any indebtedness that
becomes indebtedness of the Guarantor or a Subsidiary of the Guarantor as a result of such
transaction as having been incurred by the Guarantor or such Subsidiary at the time of such
transaction, no Default or Event of Default shall have happened and be continuing; and

9

 

	(3)	 	the Guarantor has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation, amalgamation, merger, sale, lease, conveyance,
transfer or other disposition and, if a supplemental indenture is required in connection with
such transaction, such supplemental indenture complies with Sections 803 and 804 and that all
conditions precedent herein provided for relating to such transaction have been complied with.

     SECTION 804. Successor Person Substituted for Guarantor.

     Upon any consolidation or amalgamation the Guarantor with or merger by the Guarantor into any
other Person or any sale, lease, conveyance, transfer or other disposition of all or substantially
all of the properties and assets of the Guarantor in accordance with Section 803, the successor
Person formed by such consolidation or amalgamation or into which the Guarantor is merged or to
which such sale, lease, conveyance, transfer or other disposition is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Guarantor under this Indenture with
the same effect as if such successor Person had been named as the Guarantor herein and thereafter,
except in the case of such lease, the predecessor Person shall be relieved of all obligations and
covenants under this Indenture and the Guarantee.

     2.5 Amendments to Article Ten of the Indenture (Covenants). Article Ten of the
Indenture is hereby amended in respect of, and applicable to, the Notes and only in respect of, and
applicable to, the Notes by (a) amending and restating in their
entirety Sections 1004 through 1006
as set forth below, and (b) adding thereto the following new Sections 1008 and 1009:

     SECTION
1004. Existence.

     Subject to Article Eight, each of the Company and the Guarantor will do or cause to be done
all things necessary to preserve and keep in full force and effect its corporate existence.

     SECTION
1005. Statement by Officers as to Default.

     Each of the Company and the Guarantor will deliver to the Trustee, within 120 days after the
end of each fiscal year ending after the date hereof so long as any Security is outstanding
hereunder, an Officers’ Certificate, complying with Section 314(a)(4) of the Trust Indenture Act
and stating that a review of the activities of the Company or the Guarantor, as applicable, during
such year and of performance under this Indenture has been made under the supervision of the
signers thereof and whether or not to the best of their knowledge, based upon such review, the
Company or the Guarantor, as applicable, is in default in the performance, observance or
fulfillment of any of its covenants and other obligations under this Indenture, and if the Company
or Guarantor shall be in default, specifying each such default known to them and the nature and
status thereof. One of the officers signing the Officers’ Certificate on behalf of the Guarantor
delivered pursuant to this Section 1005 shall be the principal executive, financial or accounting
officer of the Guarantor.

     For
purposes of this Section 1005, such compliance shall be determined without regard to any
period of grace or requirement of notice provided under this Indenture.

10

 

     SECTION
1006. Waiver of Certain Covenants.

     The Company and the Guarantor may omit in any particular instance to comply with any covenant
or condition set forth in Sections 1001 through 1005 and 1007
through 1009, inclusive, or any
covenant added for the benefit of any series of Securities as contemplated by Section 301 (unless
otherwise specified pursuant to Section 301) if before or after the time for such compliance the
Holders of a majority in principal amount of the Outstanding Securities of all series affected by
such omission (acting as one class) shall, by Act of such Holders, either waive such compliance in
such instance or generally waive compliance with such covenant or condition, but no such waiver
shall extend to or affect such covenant or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company or the Guarantor, as
applicable, and the duties of the Trustee in respect of any such covenant or condition shall remain
in full force and effect.

     SECTION 1008. Limitations on Liens.

     The Guarantor will not, and will not permit any of its Subsidiaries to, issue, assume or
guarantee any Indebtedness for borrowed money secured by any Lien upon any Principal Property or
any shares of stock or indebtedness of any Subsidiary of the Guarantor that owns or leases a
Principal Property (whether such Principal Property, shares of stock or indebtedness are now owned
or hereafter acquired) without making effective provision whereby the Notes (together with, if the
Guarantor shall so determine, any other Indebtedness or other obligation) shall be secured equally
and ratably with (or, at the option of the Guarantor, prior to) the Indebtedness so secured for so
long as such Indebtedness is so secured. The foregoing restrictions do not, however, apply to
Indebtedness secured by Permitted Liens.

     Notwithstanding the foregoing, the Guarantor and its Subsidiaries may, without securing the
Notes, issue, assume or guarantee secured Indebtedness that would otherwise be subject to the
foregoing restrictions in an aggregate principal amount that, together with all other such
Indebtedness of the Guarantor and its Subsidiaries that would otherwise be subject to the foregoing
restrictions (including Indebtedness permitted to be secured under clause (i) under the definition
of Permitted Liens but excluding Indebtedness permitted to be secured under clauses (ii) through
(xiv) thereunder) and the aggregate amount of Attributable Indebtedness deemed outstanding with
respect to Sale/Leaseback Transactions (other than those in connection with which the Guarantor has
voluntarily retired any of the Notes, any Pari Passu Indebtedness or any Funded Indebtedness
pursuant to clause (c) of Section 1009 hereof), does not at any one time exceed 15% of Consolidated
Net Tangible Assets.

     SECTION 1009. Limitation on Sale/Leaseback Transactions.

     The Guarantor will not, and will not permit any of its Subsidiaries to, enter into any
Sale/Leaseback Transaction with any Person (other than the Guarantor or a Subsidiary of the
Guarantor) unless: (a) the Guarantor or such Subsidiary would be entitled to incur Indebtedness in
a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback
Transaction secured by a Lien on the property subject to such Sale/Leaseback Transaction pursuant
to Section 1008 hereof without equally and ratably securing the Notes pursuant to such

11

 

covenant;
(b) after the date of  first issuance of the Notes  and within a
period commencing nine months prior to the consummation of such Sale/Leaseback Transaction and
ending nine months after the consummation thereof, the Guarantor or such Subsidiary shall have
expended for property used or to be used in the ordinary course of business of the Guarantor and
its Subsidiaries an amount equal to all or a portion of the net proceeds of such Sale/Leaseback
Transaction and the Guarantor shall have elected to designate such amount as a credit against such
Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth
in clause (c) below or as otherwise permitted); or (c) the Company or the Guarantor, during the
nine-month period after the effective date of such Sale/Leaseback Transaction, shall have applied
to either (i) the voluntary defeasance or retirement of any Notes, any Pari Passu Indebtedness or
any Funded Indebtedness or (ii) the acquisition of one or more Principal Properties at fair value,
an amount equal to the greater of the net proceeds of the sale or transfer of the property leased
in such Sale/Leaseback Transaction and the fair value, as determined by the Guarantor Board of
Directors, of such property as of the time of entering into such Sale/Leaseback Transaction (in
either case adjusted to reflect the remaining term of the lease and any amount expended by the
Guarantor as set forth in clause (b) above), less an amount equal to the sum of the principal
amount of Notes, Pari Passu Indebtedness and Funded Indebtedness voluntarily defeased or retired by
the Company or the Guarantor plus any amount expended to acquire any Principal Properties
at fair value, within such nine-month period and not designated as a credit against any other
Sale/Leaseback Transaction entered into by the Guarantor or any Subsidiary of the Guarantor during
such period.

     2.6 Amendments to Article Five of the Indenture (Events of Default). Article Five of
the Indenture is hereby amended in respect of, and applicable to, the Notes and only in respect of,
and applicable to, the Notes by

     
 (a) amending and restating in their entirety clauses (4), (5) and
(6) as set forth below.

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

of their respective affairs, and the continuance of any such decree or order for relief or any such other decree
or order unstayed and in effect for a period of 90 consecutive days; or

     (6) the commencement by the Company or the Guarantor of a voluntary case or proceeding under
any applicable federal or state bankruptcy, insolvency, reorganization or other similar law or of
any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or the Guarantor  to the
entry of a decree or order for relief in respect of the Company or the Guarantor in an involuntary
case or proceeding under any applicable federal or state bankruptcy, insolvency, reorganization or
other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against
the Company or the Guarantor, or the filing by the Company or the Guarantor, of a petition or answer or consent seeking reorganization or relief under
any applicable federal or state law, or the consent by the Company or the Guarantor to the filing of such petition or to the
appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee,
sequestrator or similar official of the Company or the Guarantor or of any substantial part of its
property, or the making by the Company or the Guarantor of an assignment for the benefit of creditors, or the admission by the Company or the Guarantor
in writing of its inability to pay its debts generally as they become
due; or

 and (b) adding immediately after clause (7) the following new clauses (8) and (9),
which shall constitute additional Events of Default with
respect to the Notes as contemplated by clause (7) of Article Five:

or evidenced any Indebtedness (other than Non-Recourse Indebtedness) of either of the Guarantor or
any Subsidiary of the Guarantor resulting in the acceleration of such Indebtedness (other than
Non-Recourse Indebtedness), or any default in payment of such Indebtedness (other than Non-Recourse
Indebtedness) (after expiration of any applicable grace periods and presentation of any debt
instruments, if required), if the aggregate amount of all such Indebtedness (other than
Non-Recourse Indebtedness) that has been so accelerated and with respect to which there has been
such a default in payment shall exceed $25,000,000 and there has been a failure to obtain
rescission or annulment of all such accelerations or to discharge all such defaulted indebtedness
within 20 days after there has been given, by registered or certified mail, to the Guarantor by the
Trustee or to the Guarantor and the Trustee by the Holders of at least 25% in principal amount of
all Outstanding Notes a written notice specifying such default or breach and requiring it to be
remedied and stating that such notice is a “Notice of Default” under the Indenture; or

     2.7
Amendments to Article Eleven of the Indenture (Redemption of

Redemption Price of all the Notes that are to be redeemed on that date.

     SECTION 1106. Notes Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein specified, and from and
after such date (unless the Company shall default in the payment of the Redemption Price) such
Notes shall cease to accrue interest. Upon surrender of any such Note for redemption in accordance
with said notice, such Notes shall be paid by the Company at the Redemption Price.

     If any Notes called for redemption shall not be so paid upon surrender thereof for redemption,
the Redemption Price thereof shall accrue interest at the rate of 5.875% per annum.

     2.8
Amendments to Section 902 of
the Indenture.  Section 902 of the Indenture is amended by adding thereto, in respect of the

Agreement to Guarantee.  In addition to the other covenants and
agreements of Guarantor in this First Supplemental Indenture, the Guarantor hereby agrees as follows:

          (a) Subject to Subsection 3(b) below, the Guarantor (or any successor person pursuant to the
applicable provisions of this First Supplemental Indenture) hereby irrevocably and unconditionally
guarantees (such guarantee being the “Guarantee”) to each Holder of a Note authenticated
and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the
validity and enforceability of the Indenture and the Notes thereunder, that: (i) the principal of,
premium, if any, and interest on the Notes promptly will be paid in full when due, whether at the
Maturity, by acceleration, call for redemption or otherwise, and interest on the overdue principal,
premium, if any, and interest, if any, on the Notes, if lawful, and all other payment obligations
of the Company to the Holders and the Trustee under the Indenture and the Notes thereunder will be
promptly paid in full, all in accordance with the terms of the Indenture and the Notes thereunder,
and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other
payment obligations, the same will be promptly paid in full when due in accordance with the terms
of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Failing
payment when due by the Company of any amount so guaranteed for whatever reason, the Guarantor
shall be obligated to pay the same immediately. The Guarantor hereby agrees that its obligations
hereunder shall be full and unconditional, irrespective of

14

 

the validity, regularity or enforceability of the Indenture or the Notes thereunder, the absence of
any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to
any provisions of the Indenture or the Notes thereunder, the recovery of any judgment against the
Company, or any action to enforce the same or any other circumstance that might otherwise
constitute a legal or equitable discharge or defense of a guarantor. The Guarantor hereby waives
presentment, demand of payment, protest, notice and all demands whatsoever and covenants that this
Guarantee shall not be discharged except by complete performance of the obligations contained in
the Notes and the Indenture.

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

     (c) The Guarantor will,
with respect to the Guarantee, pay Tax Additional Amounts, subject to the requirements and limitations in
Section 312, with respect to any Withholding Tax imposed by or for the account of any Taxing Jurisdiction
with respect to any payments made under the Guarantee. 

     Section 4. Execution and Delivery of Guarantee. To evidence the Guarantee set forth in
Section 3, the Company and the Guarantor hereby agree that a notation of such Guarantee shall be
endorsed on each Note authenticated and delivered by the Trustee, that such notation of such
Guarantee shall be in the form attached hereto as Exhibit B, and shall be executed on behalf of the
Guarantor by an officer thereof.

     The Guarantor hereby agrees that the Guarantee set forth in Section 3 shall remain in full
force and effect notwithstanding any failure to endorse on each Note a notation of the Guarantee.

     Section 5. Limitation on Individual Liability. No recourse under or upon any
obligation, covenant or agreement contained in this First Supplemental Indenture or the Guarantee,
or for any claim based thereon or otherwise in respect thereof, shall be had against any
incorporator, member, shareholder, officer or director, as such, past, present or future, of the
Guarantor, the Company or any successor Person, either directly or through the Guarantor or the
Company, whether by virtue of any constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise; it being expressly understood that this First Supplemental
Indenture and the obligations issued hereunder are solely corporate obligations, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, the incorporators,
members, shareholders, officers or directors, as such, of the Guarantor, the Company or any
successor Person, or any of them, because of the creation of the indebtedness hereby authorized, or
under or by reason of the obligations, covenants or agreements contained in this First Supplemental
Indenture or in the Guarantee or implied therefrom; and that any and all such personal liability of
every name and nature, either at common law or in equity or by constitution or statute, of, and any
and all such rights and claims against, every such incorporator, member, shareholder, officer or
director, as such, because of the creation of the indebtedness hereby authorized, or under or by
reason of the obligations, covenants or agreements contained in this First Supplemental Indenture
or in the Guarantee or implied therefrom, are hereby expressly waived and released as a condition
of, and as a consideration for, the execution of this First Supplemental Indenture and the issuance
of the Guarantee.

in respect of the Notes shall be made at the office or agency of the Company maintained for that
purpose in the City and State of New York. The Company will pay cash amounts in money of the United

     4. Indenture. The Company issued the Notes under an Indenture, dated as of November
21, 2008, between the Company and the Trustee, as supplemented by a First Supplemental Indenture,
dated as of November 21, 2008, between the Company, the Trustee and Noble Corporation, as Guarantor
(collectively, the “Indenture”). The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (the “Trust Indenture Act of 1939”). Capitalized terms used herein and not defined
herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all such
terms, and Holders are referred to the Indenture and the Trust Indenture Act of 1939 for a
statement of those terms.

     The Notes
are general unsecured obligations of the Company, initially limited to $250,000,000 aggregate
principal amount, subject to the Company’s ability to issue additional Notes as provided in the Indenture.

     5. Redemption at the Option of the Company. No sinking fund is provided for the Notes.
The Notes will be subject to redemption at the option of the Company, in whole or in part, at any
time and from time to time, upon not less than 30 nor more than 60 days’ notice to the Holders
prior to the Redemption Date, at the Redemption Price (as defined in the Indenture).

     If notice of redemption has been given as provided in Article Eleven of the Indenture and
funds for the redemption of any Notes called for redemption shall have been made available on the
Redemption Date referred to in such notice, such Notes will cease to bear interest on the date
fixed for such redemption specified in such notice and the only right of the Holders of the Notes
from and after the Redemption Date will be to receive payment of the Redemption Price upon
surrender of such Notes in accordance with such notice.

Registrar may require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The
Company shall not be required to exchange or register a transfer of (a) any Notes for a period of
15 days next preceding the first mailing or publication of notice of redemption of Notes to be
redeemed or (b) any Notes selected, called or being called for redemption, in whole or in part,
except, in the case of any Note to be redeemed in part, the portion thereof not so to be redeemed.

owner of this Note for all purposes.

     9. Unclaimed Money. The Trustee and each Paying Agent shall each return to the Company
upon written request any money held by them for the payment of any amount with respect to the Notes
that remains unclaimed for three years. After return to the Company, Holders entitled to the money
must look to the Company for payment as general creditors unless an applicable abandoned property
law designates another person.

     10. Amendment; Waiver. Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Notes may be amended with the written consent of the Holders of a majority in
aggregate principal amount of the Notes at the time Outstanding and (ii) certain defaults or
noncompliance with certain provisions may be waived with the written consent of the Holders of a
majority in aggregate principal amount of the Notes at the time Outstanding. Subject to certain
exceptions set forth in the Indenture, without the consent of any Holder, the Company and the
Trustee may amend the Indenture or the Notes to cure any ambiguity, defect or inconsistency, or to
comply with Article Nine of the Indenture, or to make any change that does not adversely affect the
rights of any Holder of Notes in any material respect.

     11. Defaults and Remedies. If an Event of Default occurs relating to certain bankruptcy events as provided in the Indenture,
the principal amount of and accrued interest on the Notes shall automatically become due and
payable without any action of the Trustee or the Holders of Notes.  Except as provided in the
Indenture, if any other Event of Default shall occur and be continuing, the Trustee or the Holders
of not less than 25% in aggregate principal amount of the Notes then Outstanding, by notice in
writing to the Company (and to the Trustee, if given by the Holders), may declare the principal
of and accrued interest on all of the Notes and the interest, if any, accrued thereon to be due and
payable immediately.

     The Company is required to furnish to the Trustee annually a certificate as to compliance by
the Company with all conditions and covenants under the Indenture.

or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and
collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee.

as such, of the Company or the Guarantor shall not have any liability for any obligations of the
Company or the payment obligations of the Guarantor under the Notes or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their creation. By accepting a
Note, each Holder waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Notes and the Guarantee.
