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. If, but only if, Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record. 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 or so voting at any such meeting. Proof of execution
of any such instrument or of a writing appointing any such agent, or of the
holding by any Person of a Security,

11

 

	 	 	 	shall be sufficient for any purpose of this Indenture and (subject to
Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee
and the Company and any agent of the Trustee or the Company, if made in the
manner provided in this Section. The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1406.

     Without limiting the generality of this Section 104, unless otherwise provided in or pursuant
to this Indenture, a Holder, including a U.S. Depository that is a Holder of a global Security, may
make, give or take, by a proxy, or proxies, duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this
Indenture to be made, given or taken by Holders, and a U.S. Depository that is a Holder of a global
Security may provide its proxy or proxies to the beneficial owners of interests in any such global
Security through such U.S. Depository’s standing instructions and customary practices.

     The Trustee shall fix a record date for the purpose of determining the Persons who are
beneficial owners of interest in any permanent global Security held by a U.S. Depository entitled
under the procedures of such U.S. Depository to make, give or take, by a proxy or proxies duly
appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or
other Act provided in or pursuant to this Indenture to be made, given or taken by Holders. If such
a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request, demand, authorization,
direction, notice, consent, waiver or other Act, whether or not such Holders remain Holders after
such record date. No such request, demand, authorization, direction, notice, consent, waiver or
other Act shall be valid or effective if made, given or taken more than 90 days after such record
date.

	 	(ii)	 	The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee
may determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.
	 
	 	(iii)	 	The ownership, principal amount and serial numbers of
Registered Securities held by any Person, and the date of the commencement and
the date of the termination of holding the same, shall be proved by the
Security Register.
	 
	 	(iv)	 	The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company,
wherever situated, if such certificate shall be deemed by the Company and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer

12

 

	 	 	 	Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is
produced, or (2) such Bearer Security is produced to the Trustee by some
other Person, or (3) such Bearer Security is surrendered in exchange for a
Registered Security, or (4) such Bearer Security is no longer Outstanding.
The ownership, principal amount and serial numbers of Bearer Securities held
by the Person so executing such instrument or writing and the date of the
commencement and the date of the termination of holding the same may also be
proved in any other manner which the Company and the Trustee deem
sufficient.

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

     Section 105. Notices, etc. to Trustee and Company.

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

13

 

     (1) the Trustee by any Holder or 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 and Escrow Services, or

     (2) the Company by the Trustee or 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 the attention of its Treasurer at the address of its principal office
specified in the first paragraph of this instrument or at any other address previously furnished in
writing to the Trustee by the Company.

     Section 106. Notice to Holders of Securities; Waiver.

     Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture
provides for notice to Holders of Securities of any event,

     (1) such notice shall be sufficiently given to Holders of Registered Securities if in writing
and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such
event, at his address 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; and

     (2) such notice shall be sufficiently given to Holders of Bearer Securities, if any, if
published in an Authorized Newspaper in The City of New York and, if such Securities are then
listed on any stock exchange outside the United States, in an Authorized Newspaper in such city as
the Company shall advise the Trustee that such stock exchange so requires, on a Business Day at
least twice, the first such publication to be not earlier than the earliest date and the second
such publication not later than the latest date prescribed for the giving of such notice.

     In any case where notice to Holders of Registered 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
Registered Security shall affect the sufficiency of such notice with respect to other Holders of
Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as
provided herein. Any notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given or provided. In the case by reason of the suspension of regular
mail service or by reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall constitute a
sufficient notification for every purpose hereunder.

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

     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

14

 

waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities
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 107. Language of Notices.

     Any request, demand, authorization, direction, notice, consent, election or waiver required or
permitted under this Indenture shall be in the English language, except that, if the Company so
elects, any published notice may be in an official language of the country of publication.

     Section 108. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any duties under any required
provision of the Trust Indenture Act imposed hereon by Section 318(c) thereof, such required
provision shall control.

     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 so expressed or not.

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, any Security or any Coupon, express or implied, shall give to any
Person, other than the parties hereto, any Security Registrar, any Paying Agent and their

equitable right, remedy or claim under this Indenture.

     Section 113. Governing Law.

     This Indenture, the Securities and any Coupons shall be governed by and construed in
accordance with the laws of the State of New York applicable to agreements made or instruments
entered into and, in each case, performed in said state without regard to the conflict of laws
principles thereof.

     Section 114. Legal Holidays.

     Unless otherwise specified in or pursuant to this Indenture or any Securities, in any case
where any Interest Payment Date, Business Day following any Change in Control Purchase Date or
Stated Maturity or Maturity of any Security shall be a Legal Holiday at any Place of Payment, then
(notwithstanding any other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision shall apply in
lieu hereof) payment need not be made at such Place of Payment on such date, and no interest shall
accrue on the amount payable on such date or at such time for the period from and after such
Interest Payment Date, Business Day following any Change in Control Purchase Date, Stated Maturity
or Maturity, as the case may be, to the next succeeding Business Day.

     Section 115. Counterparts.

     This Indenture may be executed in several counterparts, each of which shall be an original and
all of which shall constitute but one and the same instrument. The exchange of copies of this
Indenture and of signature pages by facsimile or PDF transmission shall constitute effective
execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the
original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or
PDF shall be deemed to be their original signatures for all purposes.

     Section 116. Judgment Currency.

     The Company agrees, to the fullest extent that it may effectively do so under applicable law,
that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of, or premium or interest, if any, or Additional Amounts on the
Securities of any series (the “Required Currency”) into a currency in which a judgment will be
rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at 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 New York Banking Day preceding that on which a
final unappealable judgment is given and (b) the Company’s obligations under this Indenture to make
payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with clause (a)), in any
currency other than the Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required Currency expressed
to be payable in respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required Currency the amount, if
any, by which such actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being obtained for any other
sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day
except a Saturday, Sunday or a legal holiday in The City of New York or a day on which banking
institutions in The City of New York are authorized or obligated by law, regulation or executive

     Section 203. Securities in Global Form.

     Unless otherwise provided in or pursuant to this Indenture or any Securities, the Securities
shall not be issuable in temporary or permanent global form. If Securities of a series shall be
issuable in global form, any such Security may provide that it or any number of such Securities
shall represent the aggregate amount of all Outstanding Securities of such series (or such lesser
amount as is permitted by the terms thereof) from time to time endorsed thereon and may also
provide that the aggregate amount of Outstanding Securities represented thereby may from time to
time be increased or reduced to reflect exchanges. Any endorsement of any Security in global form
to reflect the amount, or any increase or decrease in the amount, or changes in the

17

 

rights of Holders, of Outstanding Securities represented thereby shall be made in such manner
and by such Person or Persons as shall be specified therein or in the Company Order to be delivered
pursuant to Section 303 or 304 with respect thereto. 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 therein or
in the applicable Company Order. If a Company Order pursuant to Section 303 or 304 has been, or
simultaneously is, delivered, any instructions by the Company with respect to a Security in global
form shall be in writing but need not be accompanied by or contained in an Officers’ Certificate
and need not be accompanied by an Opinion of Counsel.

     Notwithstanding the provisions of Section 307, unless otherwise specified in or pursuant to
this Indenture or any Securities, payment of principal of, any premium and interest on, and any
Additional Amounts in respect of, any Security in temporary or permanent global form shall be made
to the Person or Persons specified therein.

     Notwithstanding the provisions of Section 308 and except as provided in the preceding
paragraph, the Company, the Trustee and any agent of the Company and the Trustee shall treat as the
Holder of such principal amount of Outstanding Securities represented by a global Security (i) in
the case of a global Security in registered form, the Holder of such global Security in registered
form, or (ii) in the case of a global Security in bearer form, the Person or Persons specified
pursuant to Section 301.

Maturity, and the date from which interest, if any, shall accrue and except as may otherwise be
provided by the Company in or pursuant to the Board Resolution and set forth in the Officers’
Certificate or in any indenture or indentures supplemental hereto pertaining to such series of

Securities shall be authenticated and delivered by the Trustee on original issue from time to time
upon telephonic or written order of persons designated in the Officers’ Certificate or supplemental
indenture (telephonic instructions to be promptly confirmed in writing by such person) and that
such persons are authorized to determine, consistent with such Officers’ Certificate or any
applicable supplemental indenture, such terms and conditions of the Securities of such series as

series need not be issued at the same time and, unless otherwise so provided by the Company, a

21

 

     Section 303. Execution, Authentication, Delivery and Dating.

     Securities shall be executed on behalf of the Company by its Chairman of the Board, one of its
Vice Chairmen, its President, its Treasurer or one of its Vice Presidents under its corporate seal
reproduced thereon and attested by its Secretary or one of its Assistant Secretaries. Coupons shall
be executed on behalf of the Company by the Treasurer, one of its Vice Presidents or any Assistant
Treasurer of the Company. The signature of any of these officers on the Securities or any Coupons
appertaining thereto may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities, together with any Coupons appertaining thereto, executed by the
Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’
Certificate or supplemental indenture or indentures with respect to such Securities referred to in
Section 301 and a Company Order for the authentication and delivery of such Securities have been
delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the
provisions hereof and of such Securities shall authenticate and deliver such Securities. In
authenticating such Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee shall be entitled
to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be
fully protected in relying upon,

     (1) an Opinion of Counsel to the effect that:

     (a) the form or forms and terms of such Securities and Coupons, if any, have been
established in conformity with the provisions of this Indenture;

     (b) all conditions precedent to the authentication and delivery of such Securities and
Coupons, if any, appertaining thereto, have been complied with and that such Securities, and
Coupons, when completed by appropriate insertions, executed under the Company’s corporate
seal and attested by duly authorized officers of the Company, delivered by duly authorized
officers of the Company to the Trustee for authentication pursuant to this Indenture, and
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 legally
valid and binding obligations of the Company, enforceable against the Company in accordance
with their terms, except as enforcement thereof may be subject to or limited by bankruptcy,
insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent
transfer or other similar laws relating to or affecting creditors’ rights generally, and
subject to general principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law) and will entitle the Holders thereof to the benefits of this
Indenture; such Opinion of Counsel need express no opinion as to the availability of
equitable remedies;

22

 

     (c) all laws and requirements in respect of the execution and delivery by the Company
of such Securities and Coupons, if any, have been complied with; and

     (d) this Indenture has been qualified under the Trust Indenture Act; and

     (2) an Officers’ Certificate stating that, to the best knowledge of the Persons executing such
certificate, no event which is, or after notice or lapse of time would become, an Event of Default
with respect to any of the Securities shall have occurred and be continuing.

     If all the Securities of any series are not to be issued at one time, it shall not be
necessary to deliver an Opinion of Counsel and an Officers’ Certificate at the time of issuance of
each Security, but such opinion and certificate, with appropriate modifications, shall be delivered
at or before the time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate Securities of such
series for original issue will be deemed to be a certification by the Company that all conditions
precedent provided for in this Indenture relating to authentication and delivery of such Securities
continue to have been complied with.

     The Trustee shall not be required to authenticate or to cause an Authenticating Agent to
authenticate any 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 which is not reasonably acceptable to the Trustee or if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken.

     Each Registered Security shall be dated the date of its authentication. Each Bearer Security
and any Bearer Security in global form shall be dated as of the date specified in or pursuant to
this Indenture.

     No Security or Coupon appertaining thereto 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 in Section 202 or 611 executed
by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. Except as
permitted by Section 306 or 307, the Trustee shall not authenticate and deliver any Bearer Security
unless all Coupons appertaining thereto then matured have been detached and cancelled.

     Section 304. Temporary Securities.

     Pending the preparation of definitive Securities, the Company may execute and deliver to the
Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided
in Section 303, temporary Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of
the definitive Securities in lieu of which they are issued, in registered form or, if authorized in
or pursuant to this Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as the officers of the
Company executing such Securities may determine, as conclusively evidenced by their execution of
such Securities. Such temporary Securities may be in global form.

23

 

     Except in the case of temporary Securities in global form, which shall be exchanged in
accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause
definitive Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities of the same series and containing terms and provisions that are identical to
those of any temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office or Agency for such
Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or
more temporary Securities (accompanied by any unmatured Coupons appertaining thereto), the Company
shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series and containing
identical terms and provisions; provided, however, that no definitive Bearer Security, except as
provided in or pursuant to this Indenture, shall be delivered in exchange for a temporary
Registered Security; and provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions set forth in or
pursuant to this Indenture. Unless otherwise provided in or pursuant to this Indenture with respect
to a temporary global Security, until so exchanged the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive Securities of such
series.

     Section 305. Registration, Transfer and Exchange.

     With respect to the Registered Securities of each series, if any, the Company shall cause to
be kept a register (each such register being herein sometimes referred to as the “Security
Register”) at an Office or Agency for such series in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of the Registered Securities of
such series and of transfers of the Registered Securities of such series. Such Office or Agency
shall be the “Security Registrar” for that series of Securities. Unless otherwise specified in or
pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar
for each series of Securities. The Company shall have the right to remove and replace from time to
time the Security Registrar for any series of Securities; provided that no such removal or
replacement shall be effective until a successor Security Registrar with respect to such series of
Securities shall have been appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the Security Register for
such series at all reasonable times. There shall be only one Security Register for each series of
Securities.

     Upon surrender for registration of transfer of any Registered Security of any series at any
Office or Agency for such series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more new Registered
Securities of the same series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding and containing
identical terms and provisions.

     At the option of the Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series containing identical terms and provisions, in any
authorized denominations, and of a like aggregate principal amount, upon surrender of the

24

 

Securities to be exchanged at any Office or Agency for such series. Whenever any Registered
Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the exchange is
entitled to receive.

     If provided in or pursuant to this Indenture, with respect to Securities of any series, at the
option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities
of such series containing identical terms, denominated as authorized in or pursuant to this
Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured
Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce
any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company and
the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the
surrender of such missing Coupon or Coupons may be waived by the Company and the Trustee if there
is furnished to them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Bearer Security shall surrender to any
Paying Agent any such missing Coupon in respect of which such a payment shall have been made, such
Holder shall be entitled to receive the amount of such payment; provided, however, that, except as
otherwise provided in Section 1002, interest represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such series located outside
the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such Office or Agency for such series in exchange for a Registered Security of
such series and like tenor after the close of business at such Office or Agency on (i) any Regular
Record Date and before the opening of business at such Office or Agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and before the opening of business at such Office or
Agency on the related date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date or proposed date of payment,
as the case may be (or, if such Coupon is so surrendered with such Bearer Security, such Coupon
shall be returned to the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of the Registered Security issued in exchange for such
Bearer Security, but shall be payable only to the Holder of such Coupon when due in accordance with
the provisions of this Indenture.

     If provided in or pursuant to this Indenture with respect to Securities of any series, at the
option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities
upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to
such series.

     Whenever any Securities are surrendered for exchange as contemplated by the immediately
preceding two paragraphs, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to receive.

25

 

     Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture,
any global Security shall be exchangeable for definitive Securities only if (i) the Depository is
at any time unwilling, unable or ineligible to continue as Depository and a successor depository is
not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii)
the Company executes and delivers to the Trustee a Company Order to the effect that such global
Security shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with
respect to the Securities. If the beneficial owners of interests in a global Security are entitled
to exchange such interests for definitive Securities as the result of an event described in clause
(i), (ii) or (iii) of the preceding sentence, 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 in such form and denominations as are required by or pursuant
to this Indenture, and of the same series, containing identical terms and in aggregate principal
amount equal to the principal amount of such global Security, executed by the Company. On or after
the earliest date on which such interests may be so exchanged, such global Security shall be
surrendered from time to time by the U.S. Depository or such other Depository as shall be specified
in the Company Order with respect thereto, and in accordance with instructions given to the Trustee
and the U.S. Depository or such other Depository, as the case may be (which instructions shall be
in writing but need not be contained in or accompanied by an Officers’ Certificate or be
accompanied by an Opinion of Counsel), 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 as described above without charge. The Trustee shall authenticate
and make available for delivery, in exchange for each portion of such surrendered global Security,
a like aggregate principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such global Security to be exchanged, which
(unless such Securities are not issuable both as Bearer Securities and as Registered Securities, in
which case the definitive Securities exchanged for the global Security shall be issuable only in
the form in which the Securities are issuable, as provided in or pursuant to this Indenture) shall
be in the form of Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof, but subject to the satisfaction of any certification
or other requirements to the issuance of Bearer Securities; 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 the same series to be redeemed and ending on the relevant Redemption
Date; and provided, further, that (unless otherwise provided in or pursuant to this Indenture) no
Bearer Security delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any such exchange in
part, such global Security shall be returned by the Trustee to such Depository or the U.S.
Depository, as the case may be, or such other Depository or U.S. Depository referred to above in
accordance with the instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of business at the Office
or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for
such Security and before the opening of business at such Office or Agency on the next Interest
Payment Date, or (ii) any Special Record Date for such Security and before the opening of business
at such Office or Agency on the related proposed date for payment of interest or Defaulted
Interest, as the case may be, interest shall not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of such Registered Security,

26

 

but shall be payable on such Interest Payment Date or proposed date for payment, as the case
may be, only to the Person to whom interest in respect of such portion of such global Security
shall be payable in accordance with the provisions of this Indenture.

     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 entitling the Holders thereof to the
same benefits under this Indenture as the Securities surrendered upon such registration of transfer
or exchange.

     Every Registered Security presented or surrendered for registration of transfer or for
exchange or redemption shall (if so required by the Company or the Security Registrar for such
Security) be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar for such Security 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, or redemption of
Securities, but the Company may require payment of a sum sufficient to cover any tax or other
governmental charge.

     Except as otherwise provided in or pursuant to this Indenture, the Company shall not be
required (i) to issue, register the transfer of or exchange any Securities during a period
beginning at the opening of business 15 days before the day of the selection for redemption of
Securities of like tenor and the same series under Section 1103 and ending at the close of business
on the day of such selection, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption in whole or in part, except in the case of any Security to be
redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security
so selected for redemption except, to the extent provided with respect to such Bearer Security,
that such Bearer Security may be exchanged for a Registered Security of like tenor and the same
series, provided that such Registered Security shall be immediately surrendered for redemption with
written instruction for payment consistent with the provisions of this Indenture or (iv) to issue,
register the transfer of or exchange any Security which, in accordance with its terms, has been
surrendered for repayment at the option of the Holder, except the portion, if any, of such Security
not to be so repaid.

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

     If any mutilated Security or a Security with a mutilated Coupon appertaining to it is
surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the
same series containing identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding to the Coupons, if
any, appertaining to the surrendered Security.

     If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of
the destruction, loss or theft of any Security or Coupon, 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 or Coupon has been

27

 

acquired by a bona fide purchaser, the Company shall execute and, upon Company Request the
Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Security or in exchange for the Security to which a destroyed, lost or
stolen Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a new Security
of the same series containing identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons corresponding to the Coupons, if any, appertaining to
such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.

     Notwithstanding the foregoing provisions of this Section 306, in case any mutilated,
destroyed, lost or stolen Security or Coupon 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 or Coupon;
provided, however, that principal of, any premium or interest on or any Additional Amounts with
respect to any Bearer Securities shall, except as otherwise provided in Section 1002, be payable
only at an Office or Agency for such Securities located outside the United States and, unless
otherwise provided in or pursuant to this Indenture, any interest on Bearer Securities and any
Additional Amounts with respect to such interest shall be payable only upon presentation and
surrender of the Coupons appertaining thereto.

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

     Every new Security, with any Coupons appertaining thereto issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security, or in exchange for a Security to which a destroyed,
lost or stolen Coupon appertains shall constitute a separate obligation of the Company, whether or
not the destroyed, lost or stolen Security and Coupons appertaining thereto or the destroyed, lost
or stolen Coupon shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other Securities of such
series and the Coupons, if any, duly issued hereunder.

     The provisions of this Section, as amended or supplemented pursuant to this Indenture with
respect to particular Securities or generally, shall be 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 or Coupons.

     Section 307. Payment of Interest and Certain Additional Amounts; Rights to Interest and
Certain Additional Amounts Preserved.

     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to any Registered Security which shall be payable, and are punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such
Security (or one or more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest. Unless otherwise provided in or pursuant to this Indenture,
in case a Bearer Security is surrendered in exchange for a Registered Security after the close of
business at an Office or Agency for such Security on any Regular Record Date

28

 

therefor and before the opening of business at such Office or Agency on the next succeeding
Interest Payment Date therefor, such Bearer Security shall be surrendered without the Coupon
relating to such Interest Payment Date and interest shall not be payable on such Interest Payment
Date in respect of the Registered Security issued in exchange for such Bearer Security, but shall
be payable only to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to any Registered Security which shall be payable, but shall not be punctually
paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant
Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in Clause (1) or (2) below:

     (1) The Company may elect to make payment of any Defaulted Interest to the Person in whose
name such Registered Security (or a Predecessor Security thereof) shall be 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 such Registered Security and the date of the proposed
payment, and at the same time the Company shall deposit with the Trustee an amount of money 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 on or prior to the date of the proposed
payment, such money when so deposited to be held in trust for the benefit of the Person entitled to
such Defaulted Interest as in this Clause provided. Thereupon, the Trustee shall fix a Special
Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not
less than 10 days prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the Company shall cause
notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to
be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor
Security thereof) 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 of
general circulation in the Borough of Manhattan, The City of New York, 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 mailed
as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered
Security (or a Predecessor Security thereof) shall be registered at the close of business on such
Special Record Date and shall no longer be payable pursuant to the following clause (2). In case a
Bearer Security is surrendered at the Office or Agency for such Security in exchange for a
Registered Security after the close of business at such Office or Agency on any Special Record Date
and before the opening of business at such Office or Agency on the related proposed date for
payment of Defaulted Interest, such Bearer Security shall be surrendered without the Coupon
relating to such Defaulted Interest and Defaulted Interest shall not be payable on such proposed
date of payment in respect of the Registered Security issued in exchange for such Bearer

29

 

Security, but shall be payable only to the Holder of such Coupon when due in accordance with
the provisions of this Indenture.

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

     Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular
series, at the option of the Company, interest on Registered Securities that bear interest may be
paid by mailing a check to the address of the Person entitled thereto as such address shall appear
in the Security Register or by transfer to an account maintained by the payee with a bank located
in the United States.

     Subject to the foregoing provisions of this Section and Section 305, each Security delivered
under this Indenture upon registration of transfer of or in exchange for or in lieu of any other
Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried
by such other Security.

     Section 308. Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of transfer, the Company,
the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered in the Security Register as the owner of such Registered Security
for the purpose of receiving payment of principal of, any premium and (subject to Sections 305 and
307) interest on and any Additional Amounts with respect to such Registered Security and for all
other purposes whatsoever, whether or not any payment with respect to such Registered Security
shall be overdue, and neither the Company, nor the Trustee or any agent of the Company or the
Trustee shall be affected by notice to the contrary.

     The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of
any Bearer Security or the bearer of any Coupon as the absolute owner of such Security or Coupon
for the purpose of receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not any payment with respect to such Security or Coupon shall be overdue,
and neither the Company, nor the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

     No holder of any beneficial interest in any global Security held on its behalf by a Depository
shall have any rights under this Indenture with respect to such global Security, and such
Depository may be treated by the Company, the Trustee, and any agent of the Company or the Trustee
as the owner of such global Security for all purposes whatsoever. None of the Company, the Trustee,
any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect
of the records relating to or payments made on account of beneficial ownership interests of a
global Security or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

30

 

     Section 309. Cancellation.

     All Securities and Coupons surrendered for payment, redemption, registration of transfer or
exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and Coupons, as well as Securities and Coupons surrendered directly to the
Trustee for any such purpose, shall be cancelled promptly 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 cancelled promptly by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section, except as expressly
permitted by or pursuant to this Indenture. All cancelled Securities and Coupons held by the
Trustee shall be destroyed by the Trustee, unless by a Company Order the Company directs their
return to it.

     Section 310. Computation of Interest.

     Except as otherwise provided in or pursuant to this Indenture or in any Security, interest on
the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

ARTICLE FOUR

SATISFACTION AND DISCHARGE OF INDENTURE

     Section 401. Satisfaction and Discharge.

     Upon the direction of the Company by a Company Order, this Indenture shall cease to be of
further effect with respect to any series of Securities specified in such Company Order and any
Coupons appertaining thereto, and the Trustee, on receipt of a Company Order, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when

     (1) either

     (a) all Securities of such series theretofore authenticated and delivered and all
Coupons appertaining thereto (other than (i) Coupons appertaining to Bearer Securities of
such series surrendered in exchange for Registered Securities of such series and maturing
after such exchange whose surrender is not required or has been waived as provided in
Section 305, (ii) Securities and Coupons of such series which have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 306, (iii) Coupons
appertaining to Securities of such series called for redemption and maturing after the
relevant Redemption Date whose surrender has been waived as provided in Section 1107, and
(iv) Securities and Coupons of such series for whose payment money in the applicable
Currency has theretofore been deposited in trust or segregated and held in trust by the
Company and thereafter repaid to the Company or discharged from such trust, as provided in
Section 1003) have been delivered to the Trustee for cancellation; or

     (b) all Securities of such series and, in the case of (i) or (ii) below, any Coupons
appertaining thereto not theretofore delivered to the Trustee for cancellation

31

 

	 	(i)	 	have become due and payable, or
	 
	 	(ii)	 	will become due and payable at their Stated Maturity within one
year, or
	 
	 	(iii)	 	if redeemable at the option of the Company, are to be called
for redemption within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company,

and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited
with the Trustee as trust funds in trust for such purpose, money in the Currency in which such
Securities are payable in an amount sufficient to pay and discharge the entire indebtedness on such
Securities and any Coupons appertaining thereto not theretofore delivered to the Trustee for
cancellation, including the principal of, any premium and interest on, and any Additional Amounts
with respect to such Securities and any Coupons appertaining thereto, to the date of such deposit
(in the case of Securities which have become due and payable) or to the Maturity thereof, as the
case may be;

     (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 and any Coupons appertaining thereto; and

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

     In the event there are Securities of two or more series hereunder, the Trustee shall be
required to execute an instrument acknowledging satisfaction and discharge of this Indenture only
if requested to do so with respect to Securities of such series as to which it is Trustee and if
the other conditions thereto are met.

     Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of
Securities, the obligations of the Company to the Trustee under Section 606 and, if money shall
have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the
obligations of the Company and the Trustee with respect to the Securities of such series under
Sections 305, 306, 403, 1002 and 1003, with respect to the payment of Additional Amounts, if any,
with respect to such Securities as contemplated by Section 1004 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount deposited in respect
of such Additional Amounts pursuant to Section 401(1)(b)), shall survive.

     Section 402. Defeasance and Covenant Defeasance.

     (1) Unless, pursuant to Section 301, either or both of (i) defeasance of the Securities of or
within a series under clause (2) of this Section 402, or (ii) covenant defeasance of the Securities
of or within a series under clause (3) of this Section 402 shall not be applicable with respect to
the Securities of such series, then such provisions, together with the other provisions of this
Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with
respect to any Securities), shall be applicable to such Securities and any Coupons

32

 

appertaining thereto, and the Company may at its option by Board Resolution or Officers’
Certificate, at any time, with respect to such Securities and any Coupons appertaining thereto,
elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities and any
Coupons appertaining thereto upon compliance with the conditions set forth below in this Section
402.

     (2) Upon the Company’s exercise of the above option applicable to this Section 402(2) with
respect to any Securities of or within a series, the Company shall be deemed to have been
discharged from its obligations with respect to such Outstanding Securities and any Coupons
appertaining thereto on the date the conditions set forth in clause (4) of this Section 402 are
satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company
shall be deemed to have paid and discharged the entire Indebtedness represented by such Outstanding
Securities and any Coupons appertaining thereto, which shall thereafter be deemed to be
“Outstanding” only for the purposes of clause (5) of this Section 402 and the other Sections of
this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other
obligations under such Securities and any Coupons appertaining thereto and this Indenture insofar
as such Securities and any Coupons appertaining thereto are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the same), except for the
following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of
Holders of such Outstanding Securities and any Coupons appertaining thereto to receive, solely from
the trust fund described in clause (4) of this Section 402 and as more fully set forth in such
Section, payments in respect of the principal of (and premium, if any) and interest, if any, on,
and Additional Amounts, if any, with respect to, such Securities and any Coupons appertaining
thereto when such payments are due, and any rights of such Holder to convert or exchange such
Securities into Common Stock or other securities, (ii) the obligations of the Company and the
Trustee with respect to such Securities under Sections 305, 306, 1002 and 1003, with respect to the
payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 (but only
to the extent that the Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to Section 402(4)(a) below), (iii) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 402.
The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise of
its option under clause (3) of this Section 402 with respect to such Securities and any Coupons
appertaining thereto.

     (3) Upon the Company’s exercise of the above option applicable to this Section 402(3) with
respect to any Securities of or within a series, the Company shall be released from its obligations
under Sections 1005 and 1006, and, to the extent specified pursuant to Section 301, any other
covenant applicable to such Securities, with respect to such Outstanding Securities and any Coupons
appertaining thereto on and after the date the conditions set forth in clause (4) of this Section
402 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any Coupons
appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof)
in connection with any such covenant, but shall continue to be deemed “Outstanding” for all other
purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such
Outstanding Securities and any Coupons appertaining thereto, the Company may omit to comply with,
and shall have no liability in respect of, any term, condition or limitation set forth in any such
Section or such other covenant,

33

 

whether directly or indirectly, by reason of any reference elsewhere herein to any such
Section or such other covenant or by reason of reference in any such Section or such other covenant
to any other provision herein or in any other document and such omission to comply shall not
constitute a default or an Event of Default under Section 501(3) or 501(4) or otherwise, as the
case may be, but, except as specified above, the remainder of this Indenture and such Securities
and Coupons appertaining thereto shall be unaffected thereby.

     (4) The following shall be the conditions to application of clause (2) or (3) of this Section
402 to any Outstanding Securities of or within a series and any Coupons appertaining thereto:

     (a) The Company shall irrevocably have deposited or caused to be deposited with the
Trustee (or another trustee satisfying the requirements of Section 607 who shall agree to
comply with the provisions of this Section 402 applicable to it) as trust funds in trust for
the purpose of making the following payments, specifically pledged as security for, and
dedicated solely to, the benefit of the Holders of such Securities and any Coupons
appertaining thereto,

     1. an amount in Dollars or in such Foreign Currency in which such Securities
and any Coupons appertaining thereto are then specified as payable at Stated
Maturity, or

     2. Government Obligations applicable to such Securities and Coupons
appertaining thereto (determined on the basis of the Currency in which such
Securities and Coupons appertaining thereto are then specified as payable at Stated
Maturity) which through the scheduled payment of principal and interest in respect
thereof in accordance with their terms will provide, not later than one day before
the due date of any payment of principal of (and premium, if any) and interest, if
any, on such Securities and any Coupons appertaining thereto, money in an amount, or

     3. a combination thereof,

     in any case, in an amount, sufficient, without consideration of any reinvestment of
such principal and interest, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the Trustee,
to pay and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, the principal of (and premium, if any) and interest, if any,
on such Outstanding Securities and any Coupons appertaining thereto on the Stated Maturity
of such principal or installment of principal or interest on the day on which such payments
are due and payable in accordance with the terms of this Indenture and of such Securities
and any Coupons appertaining thereto.

     (b) Such defeasance or covenant defeasance shall not result in a breach or violation
of, or constitute a default under, this Indenture or any other material agreement or
instrument to which the Company is a party or by which it is bound.

34

 

     (c) No Event of Default or event which with notice or lapse of time or both would
become an Event of Default with respect to such Securities and any Coupons appertaining
thereto shall have occurred and be continuing on the date of such deposit and, with respect
to defeasance only, at any time during the period ending on the 91st day after the date of
such deposit (it being understood that this condition shall not be deemed satisfied until
the expiration of such period).

     (d) In the case of an election under clause (2) of this Section 402, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has
received from the Internal Revenue Service a letter ruling, or there has been published by
the Internal Revenue Service a Revenue Ruling, or (ii) since the date of execution of this
Indenture, there has been a change in the applicable Federal income tax law, in either case
to the effect that, and based thereon such opinion shall confirm that, the Holders of such
Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain
or loss for Federal income tax purposes as a result of such defeasance and will be subject
to Federal income tax on the same amounts, in the same manner and at the same times as would
have been the case if such defeasance had not occurred.

     (e) In the case of an election under clause (3) of this Section 402, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such
Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain
or loss for Federal income tax purposes as a result of such covenant defeasance and will be
subject to Federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such covenant defeasance had not occurred.

     (f) The Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant
defeasance under clause (2) or (3) of this Section 402 (as the case may be) have been
complied with.

     (g) Notwithstanding any other provisions of this Section 402(4), such defeasance or
covenant defeasance shall be effected in compliance with any additional or substitute terms,
conditions or limitations which may be imposed on the Company in connection therewith
pursuant to Section 301.

     (5) Subject to the provisions of the last paragraph of Section 1003, all money and Government
Obligations (or other property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 402(5) and Section 403, the “Trustee”) pursuant to clause (4) of Section 402 in respect of
any Outstanding Securities of any series and any Coupons appertaining thereto shall be held in
trust and applied by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine,
to the Holders of such Securities and any Coupons appertaining thereto of all sums due and to
become due thereon in respect of principal (and

35

 

premium, if any) and interest and Additional Amounts, if any, but such money need not be
segregated from other funds except to the extent required by law.

     Unless otherwise specified in or pursuant to this Indenture or any Security, if, after a
deposit referred to in Section 402(4)(a) has been made, (a) the Holder of a Security in respect of
which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of
such Security to receive payment in a Currency other than that in which the deposit pursuant to
Section 402(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in
respect of the Foreign Currency in which the deposit pursuant to Section 402(4)(a) has been made,
the indebtedness represented by such Security and any Coupons appertaining thereto shall be deemed
to have been, and will be, fully discharged and satisfied through the payment of the principal of
(and premium, if any), and interest, if any, on, and Additional Amounts, if any, with respect to,
such Security as the same becomes due out of the proceeds yielded by converting (from time to time
as specified below in the case of any such election) the amount or other property deposited in
respect of such Security into the Currency in which such Security becomes payable as a result of
such election or Conversion Event based on (x) in the case of payments made pursuant to clause (a)
above, the applicable market exchange rate for such Currency in effect on the second Business Day
prior to each payment date, or (y) with respect to a Conversion Event, the applicable market
exchange rate for such Foreign Currency in effect (as nearly as feasible) at the time of the
Conversion Event.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge, imposed
on or assessed against the Government Obligations deposited pursuant to this Section 402 or the
principal or interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

     Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay
to the Company from time to time upon Company Request any money or Government Obligations (or other
property and any proceeds therefrom) held by it as provided in clause (4) of this Section 402
which, in the opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, are in excess of the amount thereof
which would then be required to be deposited to effect a defeasance or covenant defeasance, as
applicable, in accordance with this Section 402.

     Section 403. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1003, all money and Government
Obligations deposited with the Trustee pursuant to Section 401 or 402 shall be held in trust and
applied by it, in accordance with the provisions of the Securities, the Coupons 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,
premium, interest and Additional Amounts for whose payment such money has or Government Obligations
have been deposited with or received by the Trustee; but such money and Government Obligations need
not be segregated from other funds except to the extent required by law.

36

 

     Section 404. Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
obligations under this Indenture and such Securities from which the Company has been discharged or
released pursuant to this Article shall be revived and reinstated as though no deposit has occurred
pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying
Agent is permitted to apply all money held in trust pursuant to this Article with respect to such
Securities in accordance with this Article; provided, however, that if the Company makes any
payment of principal of or any premium or interest on any such Security following reinstatement of
its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.

ARTICLE FIVE

     “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 be 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 such event is specifically deleted or modified in or pursuant to the supplemental indenture,
Board Resolution or Officers’ Certificate establishing the terms of such Series pursuant to this
Indenture:

breach of which is elsewhere in this Section specifically dealt with or which has been expressly
included in this Indenture solely for the benefit of a series of Securities other than such
series), and continuance of such failure or breach for a period of 60 days after there has been
given, by registered or certified mail, to the Company by the Trustee or to the Company and the
Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of such
series, a written notice specifying such failure or breach and requiring it to be remedied and
stating that such notice is a “Notice of Default” hereunder; or

     (4) if any event of default as defined in any mortgage, indenture or instrument under which
there may be issued, or by which there may be secured or evidenced, any Indebtedness

37

 

(other than Indebtedness constituting Limited Recourse Indebtedness) of the Company or any
Subsidiary, whether such Indebtedness now exists or shall hereafter be created, shall happen and
shall result in Indebtedness of the Company or any Subsidiary in excess of $25,000,000 aggregate
principal amount becoming or being declared due and payable prior to the date on which such
Indebtedness would otherwise become due and payable, and such acceleration shall not be rescinded
or annulled, or such Indebtedness shall not have been discharged, within a period of 30 days after
there shall have been given, by registered or certified mail, to the Company by the Trustee or to

     Section 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time Outstanding (other
than an Event of Default specified in clause (6) or (7) of Section 501) occurs and is continuing,
then the Trustee or the Holders of not less than 25% in principal amount of the Outstanding
Securities of such series may declare the principal of all the Securities of such series, or such
lesser amount as may be provided for in the Securities of such series, to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders),
and upon any such declaration such principal or such lesser amount shall become immediately due and
payable.

     If an Event of Default specified in clause (6) or (7) of Section 501 occurs, all unpaid
principal of and accrued interest on the Outstanding Securities of that series (or such lesser
amount as may be provided for in the Securities of such series) shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

     At any time after Securities of any series have been accelerated and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of not less than a majority in principal amount of the Outstanding Securities
of such series, by written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

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

     (a) all overdue installments of any interest on and Additional Amounts with respect to
all Securities of such series and any Coupon appertaining thereto,

     (b) the principal of and any premium on any Securities of such series which have become
due otherwise than by such declaration of acceleration and interest thereon and any
Additional Amounts with respect thereto at the rate or rates borne by or provided for in
such Securities,

     (c) to the extent that payment of such interest or Additional Amounts is lawful,
interest upon overdue installments of any interest and Additional Amounts at the rate or
rates borne by or provided for in such Securities, and

     (d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel and all other
amounts due the Trustee under Section 606; and

39

 

     (2) all Events of Default with respect to Securities of such series, other than the
non-payment of the principal of, any premium and interest on, and any Additional Amounts with
respect to Securities of such series which shall have become due solely by such declaration of
acceleration, shall 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) there is a failure to pay any installment of interest on or any Additional Amounts with
respect to any Security or any Coupon appertaining thereto when such interest or Additional Amounts
shall have become due and payable and such default continues for a period of 30 days, or

     (2) there is a failure to pay the principal of or any premium on any Security at its Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders
of such Securities and any Coupons appertaining thereto, the whole amount of money then due and
payable with respect to such Securities and any Coupons appertaining thereto, with interest upon
the overdue principal, any premium and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate
or rates borne by or provided for in such Securities, and, in addition thereto, such further amount
of money 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 to the Trustee under Section 606.

     If the Company fails to pay the money it is required to pay the Trustee pursuant to the
preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as
trustee of an express trust, may institute a judicial proceeding for the collection of the money so
due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the
same against the Company or any other obligor upon such Securities and any Coupons appertaining
thereto and collect the monies 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 and any Coupons
appertaining thereto, 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 and any Coupons appertaining thereto 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 such
Securities or in aid of the exercise of any power granted herein or therein, 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 such other
obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Trustee shall have made any demand on the Company for the payment of any overdue
principal, premium, interest or Additional Amounts) shall be entitled and empowered, by
intervention in such proceeding or otherwise,

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

     (2) 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 606.

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

     Section 505. Trustee May Enforce Claims without Possession of Securities or Coupons.

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

41

 

of each and every Holder of a Security or Coupon in respect of which such judgment has been
recovered.

     Section 506. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal, or any premium, interest or Additional Amounts, upon presentation of the
Securities or Coupons, or both, as the case may be, 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 and any predecessor Trustee under Section
606;

     SECOND: To the payment of the amounts then due and unpaid upon the Securities and any Coupons
for principal and any premium, interest and Additional Amounts 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 aggregate amounts due and payable on such Securities and Coupons for
principal and any premium, interest and Additional Amounts, respectively;

     THIRD: The balance, if any, to the Person or Persons entitled thereto.

     Section 507. Limitations on Suits.

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

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

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

     (3) such Holder or Holders have offered to the Trustee reasonable indemnity 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 such series;

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

42

 

other series, or to obtain or to seek to obtain priority or preference over any other Holders or to
enforce any right under this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all such Holders.

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

     Notwithstanding any other provision in this Indenture, the Holder of any Security or Coupon
shall have the right, which is absolute and unconditional, to receive payment of the principal of,
any premium and (subject to Sections 305 and 307) interest on, and any Additional Amounts with
respect to such Security or payment of such Coupon, as the case may be, on the respective Stated
Maturity or Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of such Holder if
provided in or pursuant to this Indenture, on the date such repayment is due, or in the case of a
Change in Control, or as to any Change in Control Purchase Notice given timely, on the Change in
Control Purchase Date) and to institute suit for the enforcement of any such payment, and such
right shall not be impaired without the consent of such Holder.

     Section 509. Restoration of Rights and Remedies.

     If the Trustee or any Holder of a Security or a Coupon 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 each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and each such Holder 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 or Coupons in the last paragraph of Section 306, no right or
remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security
or a Coupon is intended to be exclusive of any other right or remedy, and every right and remedy,
to the extent permitted by law, shall 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, to the extent permitted by
law, 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 Security or Coupon to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy
given by this Article or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such
Holder, as the case may be.

43

 

     Section 512. Control by Holders of Securities.

     Subject to Section 601(5), the Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust or power conferred
on the Trustee with respect to the Securities of such series and any Coupons appertaining thereto,
provided that

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

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

     (3) such direction is not unduly prejudicial to the rights of the other Holders of Securities
of such series not joining in such action.

     Section 513. Waiver of Past Defaults.

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

     (1) in the payment of the principal of, any premium or interest on, or any Additional Amounts
with respect to, any Security of such series or any Coupons appertaining thereto, or

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

     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. Waiver of Stay or Extension Laws.

     The Company covenants that (to the extent that it may lawfully do so) 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 expressly waives (to the extent
that it may lawfully do so) 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.

44

 

     Section 515. 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 any
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; but the provisions of this Section 515 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in principal amount of Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest,
if any, on or Additional Amounts, if any, with respect to any Security on or after the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on or after the
Redemption Date, in the case of repayment, on or after the date for repayment and, in the case of
Change of Control, on or after the date for payment of the Change of Control Purchase Price).

shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor
Trustee or Trustees with respect to the Securities of that or those series (it being understood
that any such successor Trustee may be appointed with respect to the Securities of one or more or
all of such series and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable requirements of Section
609. If, within one year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act
of the Holders of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the applicable requirements of
Section 609, become the successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the Company or the Holders
of Securities and accepted appointment in the manner required by Section 609, any Holder of a
Security 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.

     (6) 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 the Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are issued as Bearer
Securities, by publishing notice of such event once in an Authorized Newspaper in each Place of
Payment located outside the United States. Each notice shall include the name of the

49

 

successor Trustee with respect to the Securities of such series and the address of its
Corporate Trust Office.

     Section 609. Acceptance of Appointment by Successor.

     (1) Upon the appointment hereunder of any successor Trustee with respect to all Securities,
such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and 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 hereunder of
the retiring Trustee; but, on the request of the Company or such successor Trustee, such retiring
Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and, subject to Section
1003, shall duly assign, transfer and deliver to such successor Trustee all property and money held
by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in
Section 606.

     (2) Upon the appointment hereunder of any successor Trustee with respect to the Securities of
one or more (but not all) series, the Company, the retiring Trustee and such successor Trustee
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, such 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, 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 that no Trustee shall
be responsible for any notice given to, or received by, or any act or failure to act on the part of
any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture,
the resignation or removal of the retiring Trustee shall become effective to the extent provided
therein, such retiring Trustee shall have no further responsibility for the exercise of rights and
powers or for the performance of the duties and obligations vested in the Trustee under this
Indenture with respect to the Securities of that or those series to which the appointment of such
successor Trustee relates other than as hereinafter expressly set forth, 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 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 such successor Trustee, such retiring Trustee, upon payment of its charges with respect to the
Securities of that or those series to which the appointment of such successor relates and subject
to Section 1003 shall duly assign, transfer and deliver to such successor Trustee, to the extent
contemplated by such supplemental indenture, the property and money held by such

50

 

retiring Trustee hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, subject to its claim, if any, provided for in
Section 606.

     (3) Upon request of any Person appointed hereunder as a 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 (1) or (2) of this
Section, as the case may be.

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

     Section 610. 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 of the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, without
the execution or filing of any paper or any further act on the part of any of the parties hereto.
In case any Securities shall have been authenticated but not delivered by the Trustee then in
office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities.

     Section 611. Appointment of Authenticating Agent.

     The Trustee may appoint one or more Authenticating Agents acceptable to the Company with
respect to one or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of that or those series issued upon original issue, exchange,
registration of transfer, partial redemption or partial repayment 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, except as provided in or
pursuant to this Indenture, shall at all times be a corporation that would be permitted by the
Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act,
is authorized under applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture
Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.

51

 

     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 all or
substantially all of the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, provided such Corporation shall be
otherwise eligible under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and 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 the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the Company and shall (i)
mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such Authenticating Agent shall
serve, as their names and addresses appear in the Security Register, and (ii) if Securities of the
series are issued as Bearer Securities, publish notice of such appointment at least once in an
Authorized Newspaper in the place where such successor Authenticating Agent has its principal
office if such office is located outside the United States. Any successor Authenticating Agent,
upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if originally named as an Authenticating
Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

     The Company agrees to pay each Authenticating Agent from time to time reasonable compensation
for its services under this Section. If the Trustee makes such payments, it shall be entitled to be
reimbursed for such payments, subject to the provisions of Section 606.

     The provisions of Sections 308, 603 and 604 shall be applicable to each Authenticating Agent.

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

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

	 	 	 	 	 	 	 

	 	 	WELLS FARGO BANK, NATIONAL ASSOCIATION,

As Trustee	 	 
	 
	 	 	 	 	 	 
	 

	 	By
	 	 

As Authenticating Agent
	 	 
	 
	 	 	 	 	 	 
	 

	 	By
	 	 

Authorized Officer
	 	 

52

 

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

surrendered for payment, where Securities of such series may be surrendered for registration of
transfer or exchange, and where notices and demands to or upon the Company in respect of the
Securities of such series relating thereto and this Indenture may be served. If Securities of a

written notice to the Trustee of the location, and any change in the location, of such Office or
Agency. If at any time the Company shall fail to maintain any such required Office or Agency or

such presentations, surrenders, notices and demands.

     Except as otherwise provided in or pursuant to this Indenture, no payment of principal,
premium, interest or Additional Amounts with respect to Bearer Securities shall be made at any

transfer to an account maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars, payment of
principal of, any premium or interest on and any Additional Amounts with respect to

Agency designated by the Company in the Borough of Manhattan, The City of New York, if (but only
if) payment of the full amount of such principal, premium, interest or Additional Amounts at all
offices outside the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other similar
restrictions.

     The Company may also from time to time designate 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 shall
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. Unless otherwise provided in or pursuant to
this Indenture, the Company hereby designates as the Place of Payment for each series of Securities
the Borough of Manhattan, The City of New York, and initially appoints the Corporate Trust Office
of the Trustee as the Office or Agency of the Company in the Borough of Manhattan, The City of New
York for such purpose. The Company may subsequently appoint a different Office or Agency in the
Borough of Manhattan, The City of New York for the Securities of any series.

     Unless otherwise specified with respect to any Securities pursuant to Section 301, if and so
long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be
payable in a Foreign Currency, or so long as it is required under any other provision of this
Indenture, then the Company will maintain with respect to each such series of Securities, or as so
required, at least one exchange rate agent.

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

     If the Company shall at any time act as its own Paying Agent with respect to any series of
Securities, it shall, on or before each due date of the principal of, any premium or interest on or
Additional Amounts with respect to any of the Securities of such series, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum in the Currency or Currencies in which
the Securities of such series are payable (except as otherwise specified pursuant to Section 301
for the Securities of such series) sufficient to pay the principal or any premium, interest or
Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and shall promptly notify the Trustee of its action or failure so
to act.

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
shall, on or prior to each due date of the principal of, any premium or interest on or any
Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a
sum (in the Currency or Currencies described in the preceding paragraph) sufficient to pay the
principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in
trust for the benefit of the Persons entitled thereto, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

60

 

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

     (1) hold all sums held by it for the payment of the principal of, any premium or interest on
or any Additional Amounts with respect to Securities of such series in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as
provided in or pursuant to this Indenture;

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

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

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

     Except as otherwise provided herein or pursuant hereto, 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, any
premium or interest on or any Additional Amounts with respect to any Security of any series or any
Coupon appertaining thereto and remaining unclaimed for two years after such principal or any such
premium or interest or any such Additional Amounts shall have become due and payable shall be paid
to the Company on Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security or any Coupon appertaining thereto shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the Company cause to be
published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed
to Holders of Registered Securities of such series, or both, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than 30 days from the
date of such publication or mailing nor shall it be later than two years after such principal and
any premium or interest or Additional Amounts shall have become due and payable, any unclaimed
balance of such money then remaining will be repaid to the Company.

     Section 1004. Additional Amounts.

     If any Securities of a series provide for the payment of Additional Amounts, the Company
agrees to pay to the Holder of any such Security or any Coupon appertaining thereto Additional
Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in

61

 

this Indenture there is mentioned, in any context, the payment of the principal of or any
premium or interest on, or in respect of, any Security of any series or any Coupon or the net
proceeds received on the sale or exchange of any Security of any series, such mention shall be
deemed to include mention of the payment of Additional Amounts provided by the terms of such series
established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are,
were or would be payable in respect thereof pursuant to such terms, and express mention of the
payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as
excluding Additional Amounts in those provisions hereof where such express mention is not made.

     Except as otherwise provided in or pursuant to this Indenture or the Securities of the
applicable series, 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 such series of Securities
(or if the Securities of such series shall not bear interest prior to Maturity, the first day on
which a payment of principal is made), and at least 10 days prior to each date of payment of
principal 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 to the Trustee and the principal
Paying Agent or Paying Agents, if other than the Trustee, an Officers’ Certificate instructing the
Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium, if
any, or interest on the Securities of such series shall be made to Holders of Securities of such
series or the Coupons appertaining thereto who are United States Aliens without withholding for or
on account of any tax, assessment or other governmental charge described in the Securities of such
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
or Coupons, and the Company agrees to pay to the Trustee or such Paying Agent the Additional
Amounts required by the terms of such Securities. 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.

     Section 1005. Limitation on Liens.

     Nothing in this Indenture or in the Securities shall in any way restrict or prevent the
Company or any Subsidiary from issuing, assuming, guaranteeing or otherwise incurring any
indebtedness; provided, however, that neither the Company nor any Subsidiary shall issue, assume or
guaranty any notes, bonds, debentures or other similar evidences of indebtedness for money borrowed
secured by any Lien on any asset now owned or hereafter acquired by it without making effective
provision whereby any and all Securities then or thereafter outstanding shall be secured by a Lien
equally and ratably with any and all other obligations thereby secured, so long as any such
obligations shall be so secured. Notwithstanding the foregoing, the Company or any Subsidiary,
without so securing the Securities, may issue, assume or guaranty indebtedness secured by the
following Liens:

     (a) Liens existing on the date of this Indenture or provided for under the terms of
agreements existing on the date hereof;

62

 

     (b) Liens on property to secure (i) all or any portion of the cost of exploration,
production, gathering, processing, marketing, drilling or development of such property, (ii)
all or any portion of the cost of acquiring, constructing, altering, improving or repairing
any property or assets, real or personal, or improvements used in connection with such
property, and (iii) indebtedness incurred by the Company or any Subsidiary to provide funds
for the activities set forth in clauses (i) and (ii) above;

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

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

     (e) Liens on any property securing (i) indebtedness incurred in connection with the
construction, installation or financing of pollution control or abatement facilities or
other forms of industrial revenue bond financing, (ii) indebtedness issued or guaranteed by
the United States, any state or any department, agency or instrumentality of either or (iii)
indebtedness issued or guaranteed by (Y) a foreign government, any state or any department,
agency or instrumentality of either or (Z) an international finance agency or any division
or department thereof, including the World Bank, the International Finance Corp. and the
Multilateral Investment Guarantee Agency;

     (f) any Lien extending, renewing or replacing (or successive extensions, renewals or
replacements of) any Lien of the type set forth in paragraph (a) through (e) above, which
Lien exists on the date of this Indenture;

     (g) any Ordinary Course Lien (as defined below) arising, and only so long as
continuing, in the ordinary course of the Company’s business; or

     (h) Liens which secure Limited Recourse Indebtedness.

     Notwithstanding the foregoing, the Company and any one or more Subsidiaries may issue, assume
or guaranty the following indebtedness secured by Liens on assets without regard to indebtedness in
any aggregate principal amount which, together with the aggregate outstanding principal amount of
all other indebtedness of the Company and its Subsidiaries so secured (excluding indebtedness
secured by the permitted Liens described above), and the aggregate amount of Sale/Leaseback
Transaction obligations which would otherwise be subject to the provisions of Section 1006, does
not at the time such indebtedness is incurred exceed 10% of the Company’s Consolidated Net Worth as
shown on the most recent audited consolidated balance sheet of the Company and its Subsidiaries.

     Notwithstanding the foregoing, nothing in this Section 1005 shall be deemed to prohibit or
otherwise limit the following types of transactions:

     (1) (i) the sale, granting of Liens with respect to or other transfer of crude oil, natural
gas or other petroleum hydrocarbons in place, for a period of time until, or in an amount such
that, the transferee will realize therefrom a specified amount (however determined) of money or

63

 

such crude oil, natural gas or other petroleum hydrocarbons, or (ii) the sale or other
transfer of any other interest in property of the character commonly referred to as a production
payment, overriding royalty, forward sales or similar interest; and

     (2) the granting of Liens required by any contract or statute in order to permit the Company
or a Subsidiary to perform any contract or subcontract made by it with or at the request of the
United States government or any foreign government or international finance agency, any state or
any department thereof, or any agency or instrumentality thereof, or to secure partial, progress,
advance or other payments to the Company or any Subsidiary by any such entity pursuant to the
provisions of any contract or statute.

     “Lien” shall mean, with respect to any asset, any mortgage, lien, pledge, security interest or
encumbrances of any kind in respect of such asset, whether or not filed, recorded or otherwise
perfected under applicable law. The Company or any Subsidiary shall be deemed to own subject to a
Lien any asset which it has acquired or holds subject to the interest of a vendor or lessor under
any conditional sale agreement, capital lease or other title retention agreement relating to such
asset. The right of set-off, whether by operation of law or by contract, does not constitute a Lien
unless there is a related obligation to maintain a deposit of cash or other assets in respect of
which such right of set-off may be exercised.

     “Ordinary Course Lien” shall mean:

     (a) Liens for taxes, assessments or governmental changes or levies on the property of
the Company or any Subsidiary if the same shall not at the time be delinquent or thereafter
can be paid without penalty, or are being contested in good faith and by appropriate
proceedings and for which adequate reserves in accordance with generally accepted accounting
principles shall have been set aside on the books of the Company;

     (b) Liens imposed by law, such as carriers’, warehousemen’s, landlords’ and mechanics’
liens and other similar liens arising in the ordinary course of business which secure
obligations not more than 60 days past due or which are being contested in good faith by
appropriate proceedings and for which adequate reserves in accordance with generally
accepted accounting principles shall have been set aside on the books of the Company;

     (c) Liens arising out of pledges or deposits under worker’s compensation laws,
unemployment insurance, old age pensions, or other social security or retirement benefits,
or similar legislation;

     (d) Utility easements, building restrictions and such other encumbrances or charges
against real property as are of a nature generally existing with respect to properties of a
similar character and which do not in any material way affect the marketability of the same
or interfere with the use thereof in the business of the Company or its Subsidiaries, as the
case may be;

     (e) Liens arising under operating agreements or similar agreements in respect of
obligations which are not yet due or which are being contested in good faith by appropriate
proceedings;

64

 

     (f) Liens reserved in oil, gas and/or mineral leases for bonus or rental payments and
for compliance with the terms of such leases;

     (g) Liens pursuant to partnership agreements, oil, gas and/or mineral leases,
farm-out-agreements, division orders, contracts for the sale, purchase, exchange, or
processing of oil, gas and/or other hydrocarbons, unitization and pooling declarations and
agreements, operating agreements, development agreements, area of mutual interest
agreements, forward sale agreements, oil and gas delivery obligations, and other agreements
which are customary in the oil, gas and other mineral exploration, development and
production business and in the business of processing of gas and gas condensate production
of the extraction of products therefrom;

     (h) Liens on personal property (excluding the capital stock or indebtedness of any
Subsidiary) securing indebtedness maturing not more than one year from the date of its
creation; and

     (i) Liens relating to a judgment or other court-ordered award or settlement as to which
the Company has not exhausted its appellate rights.

     “Consolidated Net Worth” means the consolidated stockholders’ equity of the Company,
determined in accordance with generally accepted accounting principles.

     Section 1006. Limitation on Sale/Leaseback Transactions.

     Neither the Company nor any Subsidiary will enter into any Sale/Leaseback Transaction with any
Person (other than the Company or a Subsidiary) providing for a term of more than three years
unless:

     (a) the Company or such Subsidiary would be permitted, pursuant to the terms of Section
1005, to incur indebtedness in an aggregate principal amount equal to or exceeding the value
of the Sale/Leaseback Transaction secured by a Lien on the property subject to such
Sale/Leaseback Transaction;

     (b) since the date of this Indenture and within a period commencing six months prior to
the Sale/Leaseback Transaction and ending six months after the consummation thereof, the
Company or such Subsidiary expends for any property (including amounts expended for the
acquisition, exploration, drilling or development thereof, or for additions, alterations,
improvements or repairs thereto) an amount up to the net proceeds of such Sale/Leaseback
Transaction, and the Company elects to designate such amount as a credit against such
Sale/Leaseback Transaction (with any amount of such net proceeds not being so designated to
be applied as set forth in paragraph (c) below); or

     (c) the Company, during or immediately after the expiration of the 12 month period
following the consummation of the Sale/Leaseback Transaction, applies to the voluntary
retirement, redemption or defeasance of the Securities and its other Senior Indebtedness an
amount equal to the greater of (i) the net proceeds of the Sale/Leaseback Transaction and
(ii) the fair value, in the opinion of the Board of Directors of the

65

 

Company, of the subject property of the Sale/Leaseback Transaction at the time of such
transaction (adjusted, in either case, to reflect the remaining term of the lease and any
amount applied pursuant to paragraph (b) above), less an amount equal to the principal
amount of other Senior Indebtedness voluntarily retired by the Company during such 12-month
period.

     “Sale/Leaseback Transaction” means any arrangement providing for the leasing to the Company or
any Subsidiary by any Person (other than the Company or a Subsidiary) of any property which has
been, or is to be, sold or transferred by the Company or such Subsidiary to such Person or to any
Person (other than the Company or a Subsidiary) to which funds have been or are to be advanced by
such Person on the security of the leased property, except with respect to any lease that secures
or relates to obligations issued by or on behalf of (a) the United States, any state or any
department, agency or instrumentality of either, (b) a foreign government, any state or any
department agency or instrumentality of either, or (c) an international finance agency or any
division or department thereof, including the World Bank, the International Finance Corp. and the
Multilateral Investment Guarantee Agency, in connection with the financing of the cost of
construction, improvement or equipping of such property.

     Section 1007. Corporate Existence.

     Subject to Articles Eight and Fifteen, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence and that of each
Subsidiary and their respective rights (charter and statutory) and franchises; provided, however,
that the foregoing shall not obligate the Company or any Subsidiary to preserve any such right or
franchise if the Company or any Subsidiary shall determine that the preservation thereof is no
longer desirable in the conduct of its business or the business of such Subsidiary.

     Section 1008. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term, provision or
condition set forth in Sections 1005, 1006 or 1007 with respect to the Securities of any series if
before the time for such compliance the Holders of at least a majority in principal amount of the
Outstanding Securities of such series, by Act of such Holders, either shall waive such compliance
in such instance or generally shall have waived compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition except to the extent
so expressly waived, and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

     Section 1009. Company Statement as to Compliance; Notice of Certain Defaults.

     (1) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal
year, a written statement (which need not be contained in or accompanied by an Officers’
Certificate) signed by the principal executive officer, the principal financial officer or the
principal accounting officer of the Company, stating that

     (a) a review of the activities of the Company during such year and of its performance
under this Indenture has been made under his or her supervision, and

66

 

     (b) to the best of his or her knowledge, based on such review, (a) the Company has
complied with all the conditions and covenants imposed on it under this Indenture throughout
such year, or, if there has been a default in the fulfillment of any such condition or
covenant, specifying each such default known to him or her and the nature and status
thereof, and (b) no event has occurred and is continuing which is, or after notice or lapse
of time or both would become, an Event of Default, or, if such an event has occurred and is
continuing, specifying each such event known to him and the nature and status thereof.

     (2) The Company shall deliver to the Trustee, within five days after the occurrence thereof,
written notice of any Event of Default or any event which after notice or lapse of time or both

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

     Section 1101. Applicability of Article.

     Redemption of Securities of any series at the option of the Company as permitted or required
by the terms of such Securities shall be made in accordance with the terms of such Securities and
(except as otherwise provided herein or pursuant hereto) this Article.

     Section 1102. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution or an Officer’s Certificate. In case of any redemption at the election of the
Company of (a) less than all of the Securities of any series or (b) all of the Securities of any
series, with the same issue date, interest rate or formula, Stated Maturity and other terms, the
Company shall, at least 60 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.

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

     If less than all of the Securities of any series with the same issue date, interest rate or
formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from
the Outstanding Securities of such series not previously called for redemption, by such method as
the Trustee shall deem fair and appropriate and which may provide for the selection for redemption
of portions of the principal amount of Registered Securities of such series; provided, however,
that no such partial redemption shall reduce the portion of the principal amount of a Registered
Security of such series not redeemed to less than the minimum denomination for a Security of such
series established herein or pursuant hereto.

     The Trustee shall promptly notify the Company and the Security Registrar (if other than
itself) 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.

67

 

     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 of such Securities which has been or is
to be redeemed.

     Section 1104. Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 106, not less than 30
nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the
Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by
mailing in the manner herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect
the validity of the proceedings for the redemption of any other Securities or portion thereof.

     Any notice that is mailed to the Holder of any Registered Securities in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not such Holder
receives the notice.

     All notices of redemption shall state:

     (1) the Redemption Date,

     (2) the Redemption Price,

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

     (4) in case any Security is to be redeemed in part only, the notice which relates to such
Security shall state that on and after the Redemption Date, upon surrender of such Security, the
Holder of such Security will receive, without charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed,

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

     (6) the place or places where such Securities, together (in the case of Bearer Securities)
with all Coupons appertaining thereto, if any, maturing after the Redemption Date, are to be
surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts
pertaining thereto,

     (7) that, unless otherwise specified in such notice, Bearer Securities of any series, if any,
surrendered for redemption must be accompanied by all Coupons maturing subsequent to the date fixed
for redemption or the amount of any such missing Coupon or Coupons will be deducted from the
Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee and any
Paying Agent is furnished,

68

 

     (8) if Bearer Securities of any series are to be redeemed and any Registered Securities of
such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered
Securities not subject to redemption on the Redemption Date pursuant to Section 305 or otherwise,
the last date, as determined by the Company, on which such exchanges may be made,

     (9) the CUSIP number or the Euroclear or the Cedel reference numbers of such Securities, if
any (or any other numbers used by a Depository to identify such Securities).

     A notice of redemption mailed as contemplated by Section 106 need not identify particular
Registered 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 prior to any Redemption Date, the Company shall deposit, with respect to the Securities
of any series called for redemption pursuant to Section 1104, 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 in the applicable Currency sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless
otherwise specified pursuant to Section 301 or in the Securities of such series) any accrued
interest on and Additional Amounts with respect thereto, all such Securities or portions thereof
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 and the Coupons for such interest
appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall
be void. Upon surrender of any such Security for redemption in accordance with said notice,
together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise
provided in or pursuant to this Indenture or the Bearer Securities of such series, installments of
interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 1002), and provided,
further, that, except as otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities 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

69

 

such at the close of business on the Regular Record Dates therefor according to their terms
and the provisions of Section 307.

     If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant
Coupons maturing after the Redemption Date, such Security may be paid after deducting from the
Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender
of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or
any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from
the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such Security located
outside of the United States except as otherwise provided in Section 1002.

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

     Section 1107. Securities Redeemed in Part.

     Any Registered Security which is to be redeemed only in part shall be surrendered at any
Office or Agency for such Security (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 Registered Security or Securities of the same series, containing
identical terms and provisions, 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. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository
for such Security in global form as shall be specified in the Company Order with respect thereto to
the Trustee, without service charge, a new Security in global form in a denomination equal to and
in exchange for the unredeemed portion of the principal of the Security in global form so
surrendered.

ARTICLE TWELVE

REPAYMENT AT THE OPTION OF HOLDERS

     Section 1201. Applicability of Article.

     Securities of any series which are repayable at the option of the Holders thereof before their
Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The
repayment of any principal amount of Securities pursuant to such option of the Holder to require
repayment of Securities before their Stated Maturity, for purposes of Section 309, shall

70

 

not operate as a payment, redemption or satisfaction of the Indebtedness represented by such
Securities unless and until the Company, at its option, shall deliver or surrender the same to the
Trustee with a directive that such Securities be cancelled. Notwithstanding anything to the
contrary contained in this Section 1201, in connection with any repayment of Securities, the
Company may arrange for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders of such Securities
on or before the close of business on the repayment date an amount not less than the repayment
price payable by the Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to the extent such
payment is so paid by such purchasers.

SECURITIES IN FOREIGN CURRENCIES

     Section 1301. Applicability of Article.

     Whenever this Indenture provides for (i) any action by, or the determination of any of the
rights of, Holders of Securities of any series in which not all of such Securities are denominated
in the same Currency, or (ii) any distribution to Holders of Securities, in the absence of any
provision to the contrary in the form of Security of any particular series or pursuant to this
Indenture or the Securities, any amount in respect of any Security denominated in a Currency other
than Dollars shall be treated for any such action or distribution as that amount of Dollars that
could be obtained for such amount on such reasonable basis of exchange and as of the record date
with respect to Registered Securities of such series (if any) for such action, determination of
rights or distribution (or, if there shall be no applicable record date, such other date reasonably
proximate to the date of such action, determination of rights or distribution) as the Company may

Trustee may determine.

MEETINGS OF HOLDERS OF SECURITIES

     Section 1401. Purposes for Which Meetings May Be Called.

     A meeting of Holders of Securities of any series may be called at any time and from time to
time pursuant to this Article to make, give or take any request, demand, authorization, direction,
notice, consent, waiver or other Act provided by this Indenture to be made, given or taken by
Holders of Securities of such series.

     Section 1402. Call, Notice and Place of Meetings.

     (1) The Trustee may at any time call a meeting of Holders of Securities of any series for any
purpose specified in Section 1401, to be held at such time and at such place in the Borough of
Manhattan, The City of New York, or, if Securities of such series have been issued in whole or in
part as Bearer Securities, in London or in such place outside the United States as the Trustee
shall determine. Notice of every meeting of Holders of Securities of any series,

71

 

setting forth the time and the place of such meeting and in general terms the action proposed
to be taken at such meeting, shall be given, in the manner provided in Section 106, not less than
21 nor more than 180 days prior to the date fixed for the meeting.

     (2) In case at any time the Company (by or pursuant to a Board Resolution) or the Holders of
at least 10% in principal amount of the Outstanding Securities of any series shall have requested
the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified
in Section 1401, by written request setting forth in reasonable detail the action proposed to be
taken at the meeting, and the Trustee shall not have mailed notice of or made the first publication
of the notice of such meeting within 21 days after receipt of such request (whichever shall be
required pursuant to Section 106) or shall not thereafter proceed to cause the meeting to be held
as provided herein, then the Company or the Holders of Securities of such series in the amount
above specified, as the case may be, may determine the time and the place in the Borough of
Manhattan, The City of New York, or, if Securities of such series are to be issued as Bearer
Securities, in London for such meeting and may call such meeting for such purposes by giving notice
thereof as provided in clause (1) of this Section.

     Section 1403. Persons Entitled to Vote at Meetings.

     To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall
be (1) a Holder of one or more Outstanding Securities of such series, or (2) a Person appointed by
an instrument in writing as proxy for a Holder or Holders of one or more Outstanding Securities of
such series by such Holder or Holders. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons entitled to vote
at such meeting and their counsel, any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

     Section 1404. Quorum; Action.

     The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a
series shall constitute a quorum for a meeting of Holders of Securities of such series; provided,
however, that if any action is to be taken at such meeting with respect to a consent or waiver
which this Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series, the Persons entitled to vote 66-2/3% in
principal amount of the Outstanding Securities of such series shall constitute a quorum. In the
absence of a quorum within 30 minutes after the time appointed for any such meeting, the meeting
shall, if convened at the request of Holders of Securities of such series, be dissolved. In any
other case the meeting may be adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any
such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less
than 10 days as determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in
Section 1402(1), except that such notice need be given only once not less than five days prior to
the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an
adjourned meeting shall state expressly the percentage, as provided above, of the principal amount
of the Outstanding Securities of such series which shall constitute a quorum.

72

 

     Except as limited by the proviso to Section 902, any resolution presented to a meeting or
adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only by
the affirmative vote of the Holders of a majority in principal amount of the Outstanding Securities
of that series; provided, however, that, except as limited by the proviso to Section 902, any
resolution with respect to any consent or waiver which this Indenture expressly provides may be
given by the Holders of at least 66-2/3% in principal amount of the Outstanding Securities of a
series may be adopted at a meeting or an adjourned meeting duly convened and at which a quorum is
present as aforesaid only by the affirmative vote of the Holders of 66-2/3% in principal amount of
the Outstanding Securities of that series; and provided, further, that, except as limited by the
proviso to Section 902, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other Act which this Indenture expressly provides may be
made, given or taken by the Holders of a specified percentage, which is less than a majority, in
principal amount of the Outstanding Securities of a series may be adopted at a meeting or an
adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative
vote of the Holders of such specified percentage in principal amount of the Outstanding Securities
of such series.

     Any resolution passed or decision taken at any meeting of Holders of Securities of any series
duly held in accordance with this Section shall be binding on all the Holders of Securities of such
series and the Coupons appertaining thereto, whether or not such Holders were present or
represented at the meeting.

     Section 1405. Determination of Voting Rights; Conduct and Adjournment of Meetings.

     (1) Notwithstanding any other provisions of this Indenture, the Trustee may make such
reasonable regulations as it may deem advisable for any meeting of Holders of Securities of such
series in regard to proof of the holding of Securities of such series and of the appointment of
proxies and in regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise
permitted or required by any such regulations, the holding of Securities shall be proved in the
manner specified in Section 104 and the appointment of any proxy shall be proved in the manner
specified in Section 104 or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to certify to the holding
of Bearer Securities. Such regulations may provide that written instruments appointing proxies,
regular on their face, may be presumed valid and genuine without the proof specified in Section 104
or other proof.

     (2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
meeting, unless the meeting shall have been called by the Company or by Holders of Securities as
provided in Section 1402(2), in which case the Company or the Holders of Securities of the series
calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons
entitled to vote a majority in principal amount of the Outstanding Securities of such series
represented at the meeting.

73

 

     (3) At any meeting, each Holder of a Security of such series or proxy shall be entitled to one
vote for each $1,000 principal amount of Securities of such series held or represented by him;
provided, however, that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a Security of such
series or proxy.

     (4) Any meeting of Holders of Securities of any series duly called pursuant to Section 1402 at
which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority
in principal amount of the Outstanding Securities of such series represented at the meeting; and
the meeting may be held as so adjourned without further notice.

     Section 1406. Counting Votes and Recording Action of Meetings.

     The vote upon any resolution submitted to any meeting of Holders of Securities of any series
shall be by written ballots on which shall be subscribed the signatures of the Holders of
Securities of such series or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities of such series held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the secretary of the meeting
their verified written reports in triplicate of all votes cast at the meeting. A record, at least
in triplicate, of the proceedings of each meeting of Holders of Securities of any series shall be
prepared by the secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more persons having knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if applicable, Section 1404.
Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any
record so signed and verified shall be conclusive evidence of the matters therein stated.

ARTICLE FIFTEEN

PURCHASES OF SECURITIES UPON CHANGE IN CONTROL

     Section 1501. Purchase of Securities at Option of the Holder upon Change in Control.

     (1) If on or prior to Maturity, there shall have occurred a Change in Control (as defined
herein), the Securities shall be purchased, at the option of the Holder thereof, by the Company at
the purchase price specified in the Securities (the “Change in Control Purchase Price”), on the
date that is 35 Business Days after the occurrence of the Change in Control (the “Change in Control
Purchase Date”), subject to satisfaction by or on behalf of the Holder of the requirements set
forth in Section 1501(3).

     A “Change in Control” shall be deemed to have occurred at such time as any of the following
events shall occur:

74

 

     (a) Any person (for purposes of paragraph (a) of this Section 1501(1) only, the term
“person” shall mean a “person” as defined in or for purposes of Section 13(d)(3) or Section
14(d)(2) of the Exchange Act of 1934 (as defined herein), or any successor provision to
either of the foregoing, including any “group” acting for the purposes of acquiring, holding
or disposing of securities within the meaning of Rule 13D-5(b)(1) under the Exchange Act of
1934), together with its Affiliates and Associates (as defined herein), shall file or become
obligated to file a report under or in response to Schedule 13D or 14D-1 (or any successor
schedule, form or report) pursuant to the Exchange Act of 1934 disclosing that such person
has become the beneficial owner (as the term “beneficial owner” is defined in Rule 13d-3
under the Exchange Act of 1934, or any successor provision) of either
(A) 50% or more of the shares of Common Stock then outstanding or (B) 50% or more of the voting power of the Voting
Stock of the Company then outstanding; provided, however, that for purposes of paragraph (i)
of this Section 1501(a), a person shall not be deemed the beneficial owner of (1) any
securities tendered pursuant to a tender offer or exchange offer made by or on behalf of
such person, or its Affiliates or Associates, until such tendered securities are accepted
for purchase or exchange thereunder, or (2) any securities in respect of which beneficial
ownership by such person arises solely as a result of a revocable proxy delivered in
response to a proxy or consent solicitation that is made pursuant to, and in accordance
with, the Exchange Act of 1934 and the applicable rules and regulations thereunder and is
not then reportable on Schedule 13D (or any successor schedule, form or report) under the
Exchange Act of 1934.

     (b) There shall be consummated any sale, transfer, lease or conveyance of all or
substantially all of the properties and assets of the Company to any other Corporation or
Corporations or other person or persons (other than a Subsidiary of the Company).

     (c) There shall be consummated any consolidation of the Company with or merger of the
Company with or into any other Person (whether or not affiliated with the Company) in which
the Company is not the sole surviving or continuing corporation or
pursuant to which the shares of Common Stock outstanding immediately prior to the consummation of such
consolidation or merger are converted into cash, securities or other property, other than a
consolidation or merger in which the holders of shares of Common Stock receive, directly or
indirectly, (A) 75% or more of the common stock of the sole surviving or continuing
Corporation outstanding immediately following the consummation of such consolidation or
merger and (B) securities representing 75% or more of the combined voting power of the
Voting Stock of the sole surviving or continuing corporation outstanding immediately
following the consummation thereof of such consolidation or merger.

     “Exchange Act of 1934” shall mean the Securities Exchange Act of 1934, as amended.

     “Associate” shall have the meaning ascribed to such term in Rule 12b-2 under the Exchange Act
of 1934, as in effect on the date hereof.

     (2) Within 15 Business Days after the occurrence of a Change in Control, the Company shall
mail a written notice of Change in Control by first-class mail to the Trustee and

75

 

to each Holder (and to beneficial owners as required by applicable law, including, without
limitation, Rule 13e-4) and shall cause a copy of such notice to be published at least once in an
Authorized Newspaper located in New York City and, if any Securities are then listed on any stock
exchange located outside the United States, in an Authorized Newspaper in such city as the stock
exchange so requires. The notice shall include or transmit a form of Change in Control Purchase
Notice (as described below) to be completed by the Holder and shall state:

     (a) the events causing a Change in Control and the date of such Change in Control;

     (b) the date by which the Change in Control Purchase Notice pursuant to this Section
1601 must be given;

     (c) the Change in Control Purchase Date;

     (d) the Change in Control Purchase Price;

     (e) the name and address of the Trustee and the Office or Agency;

     (f) that the Securities must be surrendered to the Trustee or the Office or Agency to
collect payment;

     (g) that the Change in Control Purchase Price for any Security as to which a Change in
Control Purchase Notice has been duly given and not withdrawn will be paid promptly
following the later of the Change in Control Purchase Date or the time of surrender of such
Security as described in (f);

     (h) the procedures the Holder must follow to exercise rights under this Section 1501(1)
and a brief description of those rights; and

     (i) the procedures for withdrawing a Change in Control Purchase Notice.

     (3) A Holder may exercise its rights specified in Section 1501(1) upon delivery of a written
notice of purchase (a “Change in Control Purchase Notice”) to the Trustee or to the Office or
Agency at any time prior to the close of business of the Change in Control Purchase Date, stating:

     (a) the certificate number or numbers of the Security or Securities which the Holder
will deliver to be purchased;

     (b) the portion of the principal amount of the Security or Securities which the Holder
will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof;
and

     (c) that such Security or Securities shall be purchased on the Change in Control
Purchase Date pursuant to the terms and conditions specified in the Securities.

76

 

     The delivery of the Security, by hand or by registered mail prior to, on or after the Change
in Control Purchase Date (together with all necessary endorsements), to the Trustee or to the
Office or Agency shall be a condition precedent to the obligation of the Company to pay to the
Holder the Change in Control Purchase Price therefor; provided, however, that such Change in
Control Purchase Price shall be so paid pursuant to this Section 1501 only if the Security so
delivered to the Trustee or such Office or Agency shall conform in all respects to the description
thereof set forth in the related Change in Control Purchase Notice.

     Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee or to
the Office or Agency, the Change in Control Purchase Notice contemplated by this Section 1501(3)
shall have the right to withdraw such Change in Control Purchase Notice at any time prior to or on
the Change in Control Purchase Date by delivery of a written notice of withdrawal to the Trustee or
to such office or agency in accordance with Section 1502.

     Section 1502. Effect of Change in Control Purchase Notice.

     Upon receipt by the Company of the Change in Control Purchase Notice specified in Section
1501(3), the Holder of the Security in respect of which such Change in Control Purchase Notice was
given shall (unless such Change in Control Purchase Notice is withdrawn as specified in the
following paragraph) thereafter be entitled to receive solely the Change in Control Purchase Price
with respect to such Security. Such Change in Control Purchase Price shall be paid to such Holder
promptly following the later of (x) the Change in Control Purchase Date, as the case may be, with
respect to such Security (provided the conditions in Section 1501(3), as applicable, have been
satisfied) and (y) the time of delivery of such Security to the Trustee or to the Office or Agency
by the Holder thereof in the manner required by Section 1501(3), as applicable.

     A Change in Control Purchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Trustee or to the Office or Agency at any time prior to
the close of business on the Change in Control Purchase Date, specifying:

     (1) the certificate number or numbers of the Security or Securities in respect of which such
notice of withdrawal is being submitted;

     (2) the principal amount of the Security or Securities with respect to which such notice of
withdrawal is being submitted; and

     (3) the principal amount, if any, of such Security or Securities which remains subject to the
original Change in Control Purchase Notice, and which has been and will be delivered for purchase
by the Company.

     There shall be no purchase of any Securities pursuant to Section 1501 if there has occurred
and in continuing an Event of Default (other than a default in the payment of the Change in Control
Purchase Price).

77

 

     Section 1503. Deposit of Change in Control Purchase Price.

     Prior to 12:00 Noon (local time in The City of New York) on the Business Day following the
Change in Control Purchase Date, the Company shall deposit with the Trustee (or, if the Company or
a Subsidiary or an Affiliate of either of them is acting as Paying Agent, shall segregate and hold
in trust as provided in Section 1003) an amount of cash in immediately available funds or
securities, if expressly permitted hereunder, sufficient to pay the aggregate Change in Control
Purchase Price of all the Securities or portions thereof which are to be purchased. If a deposit is
made with the Trustee of the aforesaid amount of cash or securities, the Securities or portions
thereof with respect to which a Change in Control Purchase Notice has been delivered and not
validly withdrawn shall become due and payable as of the Business Day following the applicable
Change in Control Purchase Date, and on and after such date interest payable in respect of such
Securities shall cease and all other rights of the Holders thereof shall terminate, other than the
right to receive the Change in Control Purchase Price upon delivery of such Securities to the
Trustee.

     Section 1504. Covenant to Comply With Securities Laws Upon Purchase of Securities.

     In connection with any purchase of securities under Section 1601 hereof, the Company shall (a)
comply with Rule 13e-4 under the Exchange Act of 1934, if applicable, (b) file the related Schedule
13E-4 (or any successor schedule, form or report) under the Exchange Act of 1934, if applicable,
and (c) otherwise comply with all Federal and state securities laws regulating the purchase of the
Securities (including positions of the Commission under applicable no-action letters) so as to
permit the rights and obligation under Section 1501 to be exercised in the time and in the manner
specified in Section 1501 and 1502.

     Section 1505. Repayment to the Company.

     The Trustee shall return to the Company any cash, together with interest or dividends, if any,
thereon (subject to the provisions of Section 605) held by it for the payment of the Change in
Control Purchase Price of the Securities that remain unclaimed as provided in the Securities;
provided, however, that to the extent the aggregate amount of cash deposited by the Company
pursuant to Section 1503 exceeds the aggregate Change in Control Purchase Price of the Securities
or portions thereof to be purchased, then promptly after the Change in Control Purchase Date, the
Trustee shall return any such excess to the Company together with interest or dividends, if any,
thereon (subject to the provisions of Section 605).

in lieu of which other Securities have been authenticated and delivered pursuant to this

that such Security is held by a bona fide purchaser in whose hands such Security is a valid
obligation of the Company;

provided, however, that in determining whether the Holders of the requisite principal amount of
Outstanding Securities have given any request, demand, authorization, direction, notice, consent or
waiver hereunder or are present at a meeting of Holders of Securities for quorum purposes, (i) 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

equivalent, determined on the date of original issuance of such Security, of the principal amount

	 	(i)	 	Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by or pursuant to 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. If, but only if, Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record. 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 or the Guarantors. 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 or so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or
of the holding by any Person of a Security, shall be sufficient for any purpose
of this Indenture and (subject to Section 315 of the Trust Indenture Act)
conclusive in favor of the Trustee, the Company, the Guarantors, if applicable,
and any agent of the Trustee, the Company or the Guarantors, if applicable, if
made in the

12

 

	 	 	 	manner provided in this Section. The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1406.

     Without limiting the generality of this Section 104, unless otherwise provided in or pursuant
to this Indenture, a Holder, including a U.S. Depository that is a Holder of a global Security, may
make, give or take, by a proxy, or proxies, duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this
Indenture to be made, given or taken by Holders, and a U.S. Depository that is a Holder of a global
Security may provide its proxy or proxies to the beneficial owners of interests in any such global
Security through such U.S. Depository’s standing instructions and customary practices.

     The Trustee shall fix a record date for the purpose of determining the Persons who are
beneficial owners of interest in any permanent global Security held by a U.S. Depository entitled
under the procedures of such U.S. Depository to make, give or take, by a proxy or proxies duly
appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or
other Act provided in or pursuant to this Indenture to be made, given or taken by Holders. If such
a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request, demand, authorization,
direction, notice, consent, waiver or other Act, whether or not such Holders remain Holders after
such record date. No such request, demand, authorization, direction, notice, consent, waiver or
other Act shall be valid or effective if made, given or taken more than 90 days after such record
date.

	 	(ii)	 	The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee
may determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.
	 
	 	(iii)	 	The ownership, principal amount and serial numbers of
Registered Securities held by any Person, and the date of the commencement and
the date of the termination of holding the same, shall be proved by the
Security Register.
	 
	 	(iv)	 	The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company
and the Guarantors, if any, wherever situated, if such certificate shall be
deemed by the Company, the Guarantors, if any, and the Trustee to be
satisfactory, showing that at the date therein mentioned such Person had on
deposit with such depositary, or exhibited to it, the Bearer Securities therein
described; or such facts may be proved by the certificate or affidavit of the
Person holding such Bearer Securities, if such certificate or affidavit is
deemed by the Trustee to be satisfactory. The Trustee, the Company and the
Guarantors, if any, may assume that such ownership of

13

 

	 	 	 	any Bearer Security continues until (1) another certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is
produced, or (2) such Bearer Security is produced to the Trustee by some
other Person, or (3) such Bearer Security is surrendered in exchange for a
Registered Security, or (4) such Bearer Security is no longer Outstanding.
The ownership, principal amount and serial numbers of Bearer Securities held
by the Person so executing such instrument or writing and the date of the
commencement and the date of the termination of holding the same may also be
proved in any other manner which the Company, the Guarantors, if any, and
the Trustee deem sufficient.
	 
	 	(v)	 	If the Company or the Guarantors, if any, shall solicit from
the Holders of any Registered Securities any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may at its option
(but is not obligated to), by Board Resolution, fix in advance a record date
for the determination of Holders of Registered Securities entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other
Act. If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of Registered Securities of record at
the close of business on such record date shall be deemed to be Holders for the
purpose of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of such record
date; provided that no such authorization, agreement or consent by the Holders
of Registered Securities shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six
months after the record date.
	 
	 	(vi)	 	Any request, demand, authorization, direction, notice, consent,
waiver or other Act by 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 or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent, the Company or, if applicable, the Guarantors in
reliance thereon, whether or not notation of such Act is made upon such
Security.

     Section 105. Notices, etc. to Trustee, Company and Guarantors.

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

14

 

     (1) the Trustee by any Holder, the Company or the Guarantors 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 and Escrow Services, or

     (2) the Company or any of the Guarantors by the Trustee or 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 or any of the Guarantors, as applicable, addressed to
the attention of its Treasurer at the address of the Company’s principal office specified in the
first paragraph of this instrument or at any other address previously furnished in writing to the
Trustee by the Company or any of the Guarantors.

     Section 106. Notice to Holders of Securities; Waiver.

     Except as otherwise expressly provided in or pursuant to this Indenture, where this Indenture
provides for notice to Holders of Securities of any event,

     (1) such notice shall be sufficiently given to Holders of Registered Securities if in writing
and mailed, first-class postage prepaid, to each Holder of a Registered Security affected by such
event, at his address 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; and

     (2) such notice shall be sufficiently given to Holders of Bearer Securities, if any, if
published in an Authorized Newspaper in The City of New York and, if such Securities are then
listed on any stock exchange outside the United States, in an Authorized Newspaper in such city as
the Company shall advise the Trustee that such stock exchange so requires, on a Business Day at
least twice, the first such publication to be not earlier than the earliest date and the second
such publication not later than the latest date prescribed for the giving of such notice.

     In any case where notice to Holders of Registered 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
Registered Security shall affect the sufficiency of such notice with respect to other Holders of
Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as
provided herein. Any notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given or provided. In the case by reason of the suspension of regular
mail service or by reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall constitute a
sufficient notification for every purpose hereunder.

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

15

 

     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 of Securities 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 107. Language of Notices.

     Any request, demand, authorization, direction, notice, consent, election or waiver required or
permitted under this Indenture shall be in the English language, except that, if the Company or a
Guarantor so elects, any published notice may be in an official language of the country of
publication.

     Section 108. Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any duties under any required
provision of the Trust Indenture Act imposed hereon by Section 318(c) thereof, such required
provision shall control.

     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 each of the Company and the Guarantors shall
bind their respective successors and assigns, whether so expressed or not.

     Section 111. Separability Clause.

     In case any provision in this Indenture, any Security, any Coupon or, if applicable, the
Securities Guarantee 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, any Security, any Coupon or, if applicable, the Securities
Guarantee, express or implied, shall give to any Person, other than the parties hereto, any
Security Registrar, any Paying Agent and their successors hereunder and the Holders of Securities
or Coupons, any benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 113. Governing Law.

     This Indenture, the Securities, any Coupons and the Securities Guarantee shall be governed by
and construed in accordance with the laws of the State of New York applicable to

16

 

agreements made or instruments entered into and, in each case, performed in said state without
regard to the conflict of laws principles thereof.

     Section 114. Legal Holidays.

     Unless otherwise specified in or pursuant to this Indenture, any Securities or, if applicable,
the Securities Guarantee, in any case where any Interest Payment Date, Business Day following any
Change in Control Purchase Date or Stated Maturity or Maturity of any Security shall be a Legal
Holiday at any Place of Payment, then (notwithstanding any other provision of this Indenture, any
Security, any Coupon or, if applicable, the Securities Guarantee other than a provision in any
Security, Coupon or, if applicable, the Securities Guarantee that specifically states that such
provision shall apply in lieu hereof) payment need not be made at such Place of Payment on such
date, and no interest shall accrue on the amount payable on such date or at such time for the
period from and after such Interest Payment Date, Business Day following any Change in Control
Purchase Date, Stated Maturity or Maturity, as the case may be, to the next succeeding Business
Day.

     Section 115. Counterparts.

     This Indenture may be executed in several counterparts, each of which shall be an original and
all of which shall constitute but one and the same instrument. The exchange of copies of this
Indenture and of signature pages by facsimile or PDF transmission shall constitute effective
execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the
original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or
PDF shall be deemed to be their original signatures for all purposes.

     Each of the Company and the Guarantors agrees, to the fullest extent that it may effectively
do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is
necessary to convert the sum due in respect of the principal of, or premium or interest, if any, or
Additional Amounts on the Securities of any series (the “Required Currency”) into a currency in
which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the
rate at 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 New York Banking Day preceding
that on which a final unappealable judgment is given and (b) the Company’s obligations under this
Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any
tender, or any recovery pursuant to any judgment (whether or not entered in accordance with clause
(a)), in any currency other than the Required Currency, except to the extent that such tender or
recovery shall result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an
alternative or additional cause of action for the purpose of recovering in the Required Currency
the amount, if any, by which such actual receipt shall fall short of the full amount of the
Required Currency so expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York
Banking Day” means any day except a Saturday, Sunday or a legal

17

 

holiday in The City of New York or a day on which banking institutions in The City of New York
are authorized or obligated by law, regulation or executive order to be closed.

Maturity, and the date from which interest, if any, shall accrue and except as may otherwise be
provided by the Company in or pursuant to the Board Resolution and set forth in the Officers’

such persons are authorized to determine, consistent with such Officers’ Certificate or any
applicable supplemental indenture, such terms and conditions of the Securities of such series as
are specified in such Officers’ Certificate or supplemental indenture. All

22

 

Securities of any one series need not be issued at the same time and, unless otherwise so
provided by the Company, a series may be reopened for issuances of additional Securities of such
series or to establish additional terms of such series of Securities.

     If any of the terms of the Securities of any series shall be established by action taken by or
pursuant to a Board Resolution, the Board Resolutions of the Company and, if applicable, the
Guarantors shall be delivered to the Trustee at or prior to the delivery of the Officers’
Certificate setting forth the terms of such series.

     Section 302. Currency; Denominations.

     Unless otherwise provided in or pursuant to this Indenture, the principal of, any premium and
interest on and any Additional Amounts with respect to the Securities shall be payable in Dollars.
Unless otherwise provided in or pursuant to this Indenture, Registered Securities denominated in
Dollars shall be issuable in registered form without Coupons in denominations of $1,000 and any
integral multiple thereof, and the Bearer Securities denominated in Dollars shall be issuable in
the denomination of $5,000. Securities not denominated in Dollars shall be issuable in such
denominations as are established with respect to such Securities in or pursuant to this Indenture.

     Section 303. Execution, Authentication, Delivery and Dating.

     Securities shall be executed on behalf of the Company by its Chairman of the Board, one of its
Vice Chairmen, its President, its Treasurer or one of its Vice Presidents under its corporate seal
reproduced thereon and attested by its Secretary or one of its Assistant Secretaries. Coupons shall
be executed on behalf of the Company by the Treasurer, one of its Vice Presidents or any Assistant
Treasurer of the Company. The signature of any of these officers on the Securities or any Coupons
appertaining thereto may be manual or facsimile. Any Securities Guarantee endorsed on the
Securities shall be executed on behalf of the applicable Guarantor by its Chairman of the Board,
one of its Vice Chairmen, its President, its Treasurer or one of its Vice Presidents under its
corporate seal reproduced thereon and attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on any endorsement of the Securities Guarantee
may be manual or facsimile.

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

     At any time and from time to time after the execution and delivery of this Indenture, the
Company may deliver Securities, together with any Coupons appertaining thereto, executed by the
Company, with the Securities Guarantee endorsed thereon by the Guarantors, if any, to the Trustee
for authentication and, provided that the Board Resolution and Officers’ Certificate or
supplemental indenture or indentures with respect to such Securities referred to in Section 301 and
a Company Order for the authentication and delivery of such Securities and the Securities

23

 

Guarantee endorsed thereon, if any, have been delivered to the Trustee, the Trustee in
accordance with the Company Order and subject to the provisions hereof and of such Securities shall
authenticate and deliver such Securities. In authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities and any Coupons
appertaining thereto, and the Securities Guarantee endorsed thereon by the Guarantors, if any, the
Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust
Indenture Act) shall be fully protected in relying upon,

     (1) an Opinion of Counsel to the effect that:

     (a) the form or forms and terms of such Securities and Coupons, if any, have been
established in conformity with the provisions of this Indenture;

     (b) all conditions precedent to the authentication and delivery of such Securities and
Coupons, if any, appertaining thereto, and the Securities Guarantee, if any, have been
complied with and that (i) such Securities and Coupons, when completed by appropriate
insertions, executed under the Company’s corporate seal and attested by duly authorized
officers of the Company, and (ii) the Securities Guarantee, if any, executed under the
respective Guarantors’ corporate seals and attested by duly authorized officers of each of
the respective Guarantors, delivered by duly authorized officers of the Company to the
Trustee for authentication pursuant to this Indenture, and authenticated and delivered by
the Trustee and issued by the Company and the Guarantors, as applicable, in the manner and
subject to any conditions specified in such Opinion of Counsel, will constitute legally
valid and binding obligations of the Company and, if applicable, the Guarantors, enforceable
against the Company and, if applicable, the Guarantors in accordance with their terms,
except as enforcement thereof may be subject to or limited by bankruptcy, insolvency,
reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other
similar laws relating to or affecting creditors’ rights generally, and subject to general
principles of equity (regardless of whether enforcement is sought in a proceeding in equity
or at law) and will entitle the Holders thereof to the benefits of this Indenture, including
the Securities Guarantee, if applicable; such Opinion of Counsel need express no opinion as
to the availability of equitable remedies;

     (c) all laws and requirements in respect of the execution and delivery by the Company
of such Securities and Coupons, if any, have been complied with; and

     (d) this Indenture has been qualified under the Trust Indenture Act; and

     (2) an Officers’ Certificate of the Company and the Guarantors, if any, stating that, to the
best knowledge of the Persons executing such certificate, no event which is, or after notice or
lapse of time would become, an Event of Default with respect to any of the Securities, in the case
of the Person executing such certificate on behalf of the Company, or the Securities Guarantee, in
the case of the Person executing such certificate on behalf of the Guarantors, if applicable, shall
have occurred and be continuing.

24

 

     If all the Securities of any series are not to be issued at one time, it shall not be
necessary to deliver an Opinion of Counsel and an Officers’ Certificate at the time of issuance of
each Security, but such opinion and certificate, with appropriate modifications, shall be delivered
at or before the time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate Securities of such
series for original issue will be deemed to be a certification by the Company and the Guarantors,
if any, that all conditions precedent provided for in this Indenture relating to authentication and
delivery of such Securities continue to have been complied with.

     The Trustee shall not be required to authenticate or to cause an Authenticating Agent to
authenticate any 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 which is not reasonably acceptable to the Trustee or if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken.

     Each Registered Security shall be dated the date of its authentication. Each Bearer Security
and any Bearer Security in global form shall be dated as of the date specified in or pursuant to
this Indenture.

     No Security or Coupon appertaining thereto, nor any Securities Guarantee endorsed thereon,
shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose,
unless there appears on such Security a certificate of authentication substantially in the form
provided for in Section 202 or 611 executed by or on behalf of the Trustee or by the Authenticating
Agent by the manual signature of one of its authorized officers. Such certificate upon any Security
shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 306 or 307, the Trustee shall not
authenticate and deliver any Bearer Security or related Securities Guarantee unless all Coupons
appertaining thereto then matured have been detached and cancelled.

     Section 304. Temporary Securities.

     Pending the preparation of definitive Securities, the Company may execute and deliver to the
Trustee and, upon Company Order, the Trustee shall authenticate and deliver, in the manner provided
in Section 303, temporary Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of
the definitive Securities in lieu of which they are issued, in registered form or, if authorized in
or pursuant to this Indenture, in bearer form with one or more Coupons or without Coupons and
having endorsed thereon the Securities Guarantee of the Guarantors, if any, substantially of the
tenor of the definitive Securities Guarantee, if any, and with such appropriate insertions,
omissions, substitutions and other variations as the officers of the Company or Guarantors, if any,
executing such Securities or the Securities Guarantee, respectively, may determine, as conclusively
evidenced by their execution of such Securities or any Securities Guarantee, as the case may be.
Such temporary Securities may be in global form.

     Except in the case of temporary Securities in global form, which shall be exchanged in
accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause
definitive Securities to be prepared without unreasonable delay. After the preparation of

25

 

definitive Securities of the same series and containing terms and provisions that are
identical to those of any temporary Securities, such temporary Securities shall be exchangeable for
such definitive Securities, including the Securities Guarantee of the Guarantors, if any, endorsed
thereon, upon surrender of such temporary Securities at an Office or Agency for such Securities,
without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary
Securities (accompanied by any unmatured Coupons appertaining thereto), the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations of the same series and containing identical terms
and provisions, each with the Securities Guarantee of the Guarantors, if any, endorsed thereon;
provided, however, that no definitive Bearer Security, except as provided in or pursuant to this
Indenture, shall be delivered in exchange for a temporary Registered Security; and provided,
further, that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in or pursuant to this Indenture. Unless
otherwise provided in or pursuant to this Indenture with respect to a temporary global Security,
until so exchanged the temporary Securities of any series shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities of such series.

     Section 305. Registration, Transfer and Exchange.

     With respect to the Registered Securities of each series, if any, the Company shall cause to
be kept a register (each such register being herein sometimes referred to as the “Security
Register”) at an Office or Agency for such series in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of the Registered Securities of
such series and of transfers of the Registered Securities of such series. Such Office or Agency
shall be the “Security Registrar” for that series of Securities. Unless otherwise specified in or
pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar
for each series of Securities. The Company shall have the right to remove and replace from time to
time the Security Registrar for any series of Securities; provided that no such removal or
replacement shall be effective until a successor Security Registrar with respect to such series of
Securities shall have been appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the Security Register for
such series at all reasonable times. There shall be only one Security Register for each series of
Securities.

     Upon surrender for registration of transfer of any Registered Security of any series at any
Office or Agency for such series, the Company and, if applicable, the Guarantors shall execute, and
the Trustee shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Registered Securities, with an endorsement of the Securities
Guarantee, if applicable, executed by the Guarantors, of the same series denominated as authorized
in or pursuant to this Indenture, of a like aggregate principal amount bearing a number not
contemporaneously outstanding and containing identical terms and provisions.

     At the option of the Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series containing identical terms and provisions, in any
authorized denominations, and of a like aggregate principal amount, upon surrender of the

26

 

Securities to be exchanged at any Office or Agency for such series. Whenever any Registered
Securities are so surrendered for exchange, the Company and, if applicable, the Guarantors shall
execute, and the Trustee shall authenticate and deliver, the Registered Securities, with an
endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, which the
Holder making the exchange is entitled to receive.

     If provided in or pursuant to this Indenture, with respect to Securities of any series, at the
option of the Holder, Bearer Securities of such series may be exchanged for Registered Securities
of such series containing identical terms, denominated as authorized in or pursuant to this
Indenture and in the same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons and all matured
Coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce
any such unmatured Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company and
the Trustee in an amount equal to the face amount of such missing Coupon or Coupons, or the
surrender of such missing Coupon or Coupons may be waived by the Company, the Guarantors, if any,
and the Trustee if there is furnished to them such security or indemnity as they may require to
save each of them and any Paying Agent harmless. If thereafter the Holder of such Bearer Security
shall surrender to any Paying Agent any such missing Coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest represented by
Coupons shall be payable only upon presentation and surrender of those Coupons at an Office or
Agency for such series located outside the United States. Notwithstanding the foregoing, in case a
Bearer Security of any series is surrendered at any such Office or Agency for such series in
exchange for a Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of business at such
Office or Agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before
the opening of business at such Office or Agency on the related date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon is so surrendered
with such Bearer Security, such Coupon shall be returned to the Person so surrendering the Bearer
Security), and interest or Defaulted Interest, as the case may be, shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be payable only to the
Holder of such Coupon when due in accordance with the provisions of this Indenture.

     If provided in or pursuant to this Indenture with respect to Securities of any series, at the
option of the Holder, Registered Securities of such series may be exchanged for Bearer Securities
upon such terms and conditions as may be provided in or pursuant to this Indenture with respect to
such series.

     Whenever any Securities are surrendered for exchange as contemplated by the immediately
preceding two paragraphs, the Company and, if applicable, the Guarantors shall execute, and the
Trustee shall authenticate and deliver, the Securities, with an endorsement of the Securities
Guarantee, if applicable, executed by the Guarantors, which the Holder making the exchange is
entitled to receive.

27

 

     Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture,
any global Security shall be exchangeable for definitive Securities only if (i) the Depository is
at any time unwilling, unable or ineligible to continue as Depository and a successor depository is
not appointed by the Company within 90 days of the date the Company is so informed in writing, (ii)
the Company executes and delivers to the Trustee a Company Order to the effect that such global
Security shall be so exchangeable, or (iii) an Event of Default has occurred and is continuing with
respect to the Securities. If the beneficial owners of interests in a global Security are entitled
to exchange such interests for definitive Securities as the result of an event described in clause
(i), (ii) or (iii) of the preceding sentence, 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 in such form and denominations as are required by or pursuant
to this Indenture, and of the same series, containing identical terms and in aggregate principal
amount equal to the principal amount of such global Security, executed by the Company and, if
applicable, the Guarantors. On or after the earliest date on which such interests may be so
exchanged, such global Security shall be surrendered from time to time by the U.S. Depository or
such other Depository as shall be specified in the Company Order with respect thereto, and in
accordance with instructions given to the Trustee and the U.S. Depository or such other Depository,
as the case may be (which instructions shall be in writing but need not be contained in or
accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), 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 as described above without
charge. The Trustee shall authenticate and make available for delivery, in exchange for each
portion of such surrendered global Security, a like aggregate principal amount of definitive
Securities, with an endorsement of the Securities Guarantee, if applicable, executed by the
Guarantors, of the same series of authorized denominations and of like tenor as the portion of such
global Security to be exchanged, which (unless such Securities are not issuable both as Bearer
Securities and as Registered Securities, in which case the definitive Securities exchanged for the
global Security shall be issuable only in the form in which the Securities are issuable, as
provided in or pursuant to this Indenture) shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified by the beneficial owner thereof, but
subject to the satisfaction of any certification or other requirements to the issuance of Bearer
Securities; 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 the same series to be redeemed
and ending on the relevant Redemption Date; and provided, further, that (unless otherwise provided
in or pursuant to this Indenture) no Bearer Security delivered in exchange for a portion of a
global Security shall be mailed or otherwise delivered to any location in the United States.
Promptly following any such exchange in part, such global Security shall be returned by the Trustee
to such Depository or the U.S. Depository, as the case may be, or such other Depository or U.S.
Depository referred to above in accordance with the instructions of the Company referred to above.
If a Registered Security is issued in exchange for any portion of a global Security after the close
of business at the Office or Agency for such Security where such exchange occurs on or after (i)
any Regular Record Date for such Security and before the opening of business at such Office or
Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and
before the opening of business at such Office or Agency on the related proposed date for payment of
interest or Defaulted Interest, as the case may be, interest shall not be

28

 

payable on such Interest Payment Date or proposed date for payment, as the case may be, in
respect of such Registered Security, but shall be payable on such Interest Payment Date or proposed
date for payment, as the case may be, only to the Person to whom interest in respect of such
portion of such global Security shall be payable in accordance with the provisions of this
Indenture.

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

     Every Registered Security presented or surrendered for registration of transfer or for
exchange or redemption shall (if so required by the Company or the Security Registrar for such
Security) be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar for such Security 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, or redemption of
Securities, but the Company may require payment of a sum sufficient to cover any tax or other
governmental charge.

     Except as otherwise provided in or pursuant to this Indenture, the Company shall not be
required (i) to issue, register the transfer of or exchange any Securities during a period
beginning at the opening of business 15 days before the day of the selection for redemption of
Securities of like tenor and the same series under Section 1103 and ending at the close of business
on the day of such selection, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption in whole or in part, except in the case of any Security to be
redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security
so selected for redemption except, to the extent provided with respect to such Bearer Security,
that such Bearer Security may be exchanged for a Registered Security of like tenor and the same
series, provided that such Registered Security shall be immediately surrendered for redemption with
written instruction for payment consistent with the provisions of this Indenture or (iv) to issue,
register the transfer of or exchange any Security which, in accordance with its terms, has been
surrendered for repayment at the option of the Holder, except the portion, if any, of such Security
not to be so repaid.

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

     If any mutilated Security or a Security with a mutilated Coupon appertaining to it is
surrendered to the Trustee, subject to the provisions of this Section 306, the Company and, if
applicable, the Guarantors shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security, with an endorsement of the Securities Guarantee, if applicable, executed
by the Guarantors, of the same series containing identical terms and of like principal amount and
bearing a number not contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

29

 

     If there be delivered to the Company, the Guarantors, if applicable, and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security or Coupon, and
(ii) such security or indemnity as may be required by them to save each of them and any agent of
any of them harmless, then, in the absence of notice to the Company or the Trustee that such
Security or Coupon has been acquired by a bona fide purchaser, the Company and, if applicable, the
Guarantors shall execute and, upon Company Request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen Security or in exchange
for the Security to which a destroyed, lost or stolen Coupon appertains with all appurtenant
Coupons not destroyed, lost or stolen, a new Security, with an endorsement of the Securities
Guarantee, if applicable, executed by the Guarantors, of the same series containing identical terms
and of like principal amount and bearing a number not contemporaneously outstanding, with Coupons
corresponding to the Coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen Coupon appertains.

     Notwithstanding the foregoing provisions of this Section 306, in case any mutilated,
destroyed, lost or stolen Security or Coupon 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 or Coupon;
provided, however, that principal of, any premium or interest on or any Additional Amounts with
respect to any Bearer Securities shall, except as otherwise provided in Section 1002, be payable
only at an Office or Agency for such Securities located outside the United States and, unless
otherwise provided in or pursuant to this Indenture, any interest on Bearer Securities and any
Additional Amounts with respect to such interest shall be payable only upon presentation and
surrender of the Coupons appertaining thereto.

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

     Every new Security, with any Coupons appertaining thereto, and the Securities Guarantee of the
Guarantors, if any, endorsed thereon, issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security, or in exchange for a Security to which a destroyed, lost or stolen Coupon
appertains shall constitute a separate obligation of the Company and, if applicable, the
Guarantors, whether or not the destroyed, lost or stolen Security and Coupons appertaining thereto
or the destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with any and all other
Securities of such series and the Coupons, if any, duly issued hereunder.

     The provisions of this Section, as amended or supplemented pursuant to this Indenture with
respect to particular Securities or generally, shall be 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 or Coupons.

     Section 307. Payment of Interest and Certain Additional Amounts; Rights to Interest and
Certain Additional Amounts Preserved.

30

 

     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to any Registered Security which shall be payable, and are punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such
Security (or one or more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest. Unless otherwise provided in or pursuant to this Indenture,
in case a Bearer Security is surrendered in exchange for a Registered Security after the close of
business at an Office or Agency for such Security on any Regular Record Date therefor and before
the opening of business at such Office or Agency on the next succeeding Interest Payment Date
therefor, such Bearer Security shall be surrendered without the Coupon relating to such Interest
Payment Date and interest shall not be payable on such Interest Payment Date in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be payable only to the
Holder of such Coupon when due in accordance with the provisions of this Indenture.

     Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to any Registered Security which shall be payable, but shall not be punctually
paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant
Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid
by the Company or, if applicable, the Guarantors, at its or their election in each case, as
provided in Clause (1) or (2) below:

     (1) The Company or, if applicable, the Guarantors may elect to make payment of any Defaulted
Interest to the Person in whose name such Registered Security (or a Predecessor Security thereof)
shall be 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 or, if applicable,
the Guarantors shall notify the Trustee in writing of the amount of Defaulted Interest proposed to
be paid on such Registered Security and the date of the proposed payment, and at the same time the
Company or, if applicable, the Guarantors 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 on or prior to the date of the proposed
payment, such money when so deposited to be held in trust for the benefit of the Person entitled to
such Defaulted Interest as in this Clause provided. Thereupon, the Trustee shall fix a Special
Record Date for the payment of such Defaulted Interest, which shall be not more than 15 days and
not less than 10 days prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the Company shall cause
notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to
be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor
Security thereof) 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 of
general circulation in the Borough of Manhattan, The City of New York, 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 mailed
as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered
Security (or a

31

 

Predecessor Security thereof) shall be registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (2). In case a Bearer
Security is surrendered at the Office or Agency for such Security in exchange for a Registered
Security after the close of business at such Office or Agency on any Special Record Date and before
the opening of business at such Office or Agency on the related proposed date for payment of
Defaulted Interest, such Bearer Security shall be surrendered without the Coupon relating to such
Defaulted Interest and Defaulted Interest shall not be payable on such proposed date of payment in
respect of the Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

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

     Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular
series, at the option of the Company, interest on Registered Securities that bear interest may be
paid by mailing a check to the address of the Person entitled thereto as such address shall appear
in the Security Register or by transfer to an account maintained by the payee with a bank located
in the United States.

     Subject to the foregoing provisions of this Section and Section 305, each Security delivered
under this Indenture upon registration of transfer of or in exchange for or in lieu of any other
Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried
by such other Security.

     Section 308. Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of transfer, the Company,
the Trustee and, if applicable, the Guarantors and any agent thereof may treat the Person in whose
name such Registered Security is registered in the Security Register as the owner of such
Registered Security for the purpose of receiving payment of principal of, any premium and (subject
to Sections 305 and 307) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with respect to such
Registered Security shall be overdue, and none of the Company, the Trustee nor, if applicable, the
Guarantors nor any agent of any of them shall be affected by notice to the contrary.

     The Company, the Trustee and, if applicable, the Guarantors and any agent thereof may treat
the bearer of any Bearer Security or the bearer of any Coupon as the absolute owner of such
Security or Coupon for the purpose of receiving payment thereof or on account thereof and for all
other purposes whatsoever, whether or not any payment with respect to such Security or Coupon shall
be overdue, and none of the Company, the Trustee nor, if applicable, the Guarantors nor any agent
of any of them shall be affected by notice to the contrary.

32

 

     No holder of any beneficial interest in any global Security held on its behalf by a Depository
shall have any rights under this Indenture with respect to such global Security, and such
Depository may be treated by the Company, the Trustee, and, if applicable, the Guarantors and any
agent thereof as the owner of such global Security for all purposes whatsoever. None of the Company
or, if applicable, the Guarantors, the Trustee, any Paying Agent or the Security Registrar will
have any responsibility or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

     Section 309. Cancellation.

     All Securities and Coupons surrendered for payment, redemption, registration of transfer or
exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and Coupons, as well as Securities and Coupons surrendered directly to the
Trustee for any such purpose, shall be cancelled promptly 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 cancelled promptly by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section, except as expressly
permitted by or pursuant to this Indenture. All cancelled Securities and Coupons held by the
Trustee shall be destroyed by the Trustee, unless by a Company Order the Company directs their
return to it.

     Section 310. Computation of Interest.

     Except as otherwise provided in or pursuant to this Indenture or in any Security, interest on
the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

ARTICLE FOUR

SATISFACTION AND DISCHARGE OF INDENTURE

     Section 401. Satisfaction and Discharge.

     Upon the direction of the Company by a Company Order, this Indenture shall cease to be of
further effect with respect to any series of Securities specified in such Company Order and any
Coupons appertaining thereto, and the Trustee, on receipt of a Company Order, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when

     (1) either

     (a) all Securities of such series theretofore authenticated and delivered and all
Coupons appertaining thereto (other than (i) Coupons appertaining to Bearer Securities of
such series surrendered in exchange for Registered Securities of such series and maturing
after such exchange whose surrender is not required or has been waived as provided in
Section 305, (ii) Securities and Coupons of such series which have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 306, (iii) Coupons

33

 

appertaining to Securities of such series called for redemption and maturing after the
relevant Redemption Date whose surrender has been waived as provided in Section 1107, and
(iv) Securities and Coupons of such series for whose payment money in the applicable
Currency has theretofore been deposited in trust or segregated and held in trust by the
Company and thereafter repaid to the Company or discharged from such trust, as provided in
Section 1003) have been delivered to the Trustee for cancellation; or

     (b) all Securities of such series and, in the case of (i) or (ii) below, any Coupons
appertaining thereto not theretofore delivered to the Trustee for cancellation

	 	(i)	 	have become due and payable, or
	 
	 	(ii)	 	will become due and payable at their Stated Maturity within one
year, or
	 
	 	(iii)	 	if redeemable at the option of the Company, are to be called
for redemption within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company,

and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited
with the Trustee as trust funds in trust for such purpose, money in the Currency in which such
Securities are payable in an amount sufficient to pay and discharge the entire indebtedness on such
Securities and any Coupons appertaining thereto not theretofore delivered to the Trustee for
cancellation, including the principal of, any premium and interest on, and any Additional Amounts
with respect to such Securities and any Coupons appertaining thereto, to the date of such deposit
(in the case of Securities which have become due and payable) or to the Maturity thereof, as the
case may be;

     (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 and any Coupons appertaining thereto; and

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

     In the event there are Securities of two or more series hereunder, the Trustee shall be
required to execute an instrument acknowledging satisfaction and discharge of this Indenture only
if requested to do so with respect to Securities of such series as to which it is Trustee and if
the other conditions thereto are met.

     Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of
Securities, the obligations of the Company to the Trustee under Section 606 and, if money shall
have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the
obligations of the Company and the Trustee with respect to the Securities of such series under
Sections 305, 306, 403, 1002 and 1003, with respect to the payment of Additional Amounts, if any,
with respect to such Securities as contemplated by Section 1004 (but only to the

34

 

extent that the Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to Section 401(1)(b)), shall survive.

     Section 402. Defeasance and Covenant Defeasance.

     (1) Unless, pursuant to Section 301, either or both of (i) defeasance of the Securities of or
within a series under clause (2) of this Section 402, or (ii) covenant defeasance of the Securities
of or within a series under clause (3) of this Section 402 shall not be applicable with respect to
the Securities of such series, then such provisions, together with the other provisions of this
Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with
respect to any Securities), shall be applicable to such Securities and any Coupons appertaining
thereto, and the Company may at its option by Board Resolution or Officers’ Certificate, at any
time, with respect to such Securities and any Coupons appertaining thereto, elect to have Section
402(2) or Section 402(3) be applied to such Outstanding Securities and any Coupons appertaining
thereto upon compliance with the conditions set forth below in this Section 402.

     (2) Upon the Company’s exercise of the above option applicable to this Section 402(2) with
respect to any Securities of or within a series, the Company and each of the Guarantors shall be
deemed to have been discharged from their obligations with respect to such Outstanding Securities
and any Coupons appertaining thereto (including the Securities Guarantees) on the date the
conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “defeasance”).
For this purpose, such defeasance means that the Company and the Guarantors shall be deemed to have
paid and discharged the entire Indebtedness represented by such Outstanding Securities and any
Coupons appertaining thereto (including the Securities Guarantees), which shall thereafter be
deemed to be “Outstanding” only for the purposes of clause (5) of this Section 402 and the other
Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of
their other obligations under such Securities and any Coupons appertaining thereto, the Securities
Guarantees and this Indenture insofar as such Securities and any Coupons appertaining thereto and
the Securities Guarantee are concerned (and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging the same), except for the following which shall survive
until otherwise terminated or discharged hereunder: (i) the rights of Holders of such Outstanding
Securities, including any Securities Guarantee and any Coupons appertaining thereto, to receive,
solely from the trust fund described in clause (4) of this Section 402 and as more fully set forth
in such Section, payments in respect of the principal of (and premium, if any) and interest, if
any, on, and Additional Amounts, if any, with respect to, such Securities and any Coupons
appertaining thereto when such payments are due, and any rights of such Holder to convert or
exchange such Securities into Common Stock or other securities, (ii) the obligations of the Company
and the Trustee with respect to such Securities under Sections 305, 306, 1002 and 1003, with
respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section
1004 (but only to the extent that the Additional Amounts payable with respect to such Securities
exceed the amount deposited in respect of such Additional Amounts pursuant to Section 402(4)(a)
below), and any obligations of the Guarantors, if any, relating to a surviving obligation of the
Company, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv)
this Section 402. The Company may exercise its option under this Section 402(2) notwithstanding the
prior exercise of its option

35

 

under clause (3) of this Section 402 with respect to such Securities and any Coupons
appertaining thereto.

     (3) Upon the Company’s exercise of the above option applicable to this Section 402(3) with
respect to any Securities of or within a series, the Company and each of the Guarantors shall be
released from its obligations under Sections 1005 and 1006, and, to the extent specified pursuant
to Section 301, any other covenant applicable to such Securities or any Securities Guarantee
endorsed thereon, with respect to such Outstanding Securities and any Coupons appertaining thereto
on and after the date the conditions set forth in clause (4) of this Section 402 are satisfied
(hereinafter, “covenant defeasance”), and such Securities and any Coupons appertaining thereto
shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver,
consent or declaration or Act of Holders (and the consequences of any thereof) in connection with
any such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder.
For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities
and any Coupons appertaining thereto and such Securities Guarantees, the Company and the Guarantors
may omit to comply with, and shall have no liability in respect of, any term, condition or
limitation set forth in any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other covenant or by reason of
reference in any such Section or such other covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a default or an Event of Default under
Section 501(3) or 501(4) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and Coupons appertaining thereto and such
Securities Guarantees, shall be unaffected thereby.

     (4) The following shall be the conditions to application of clause (2) or (3) of this Section
402 to any Outstanding Securities of or within a series and any Coupons appertaining thereto and
any Securities Guarantees:

     (a) The Company or, if applicable, the Guarantors shall irrevocably have deposited or
caused to be deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Section 402 applicable to
it) as trust funds in trust for the purpose of making the following payments, specifically
pledged as security for, and dedicated solely to, the benefit of the Holders of such
Securities and any Coupons appertaining thereto,

     1. an amount in Dollars or in such Foreign Currency in which such Securities
and any Coupons appertaining thereto are then specified as payable at Stated
Maturity, or

     2. Government Obligations applicable to such Securities and Coupons
appertaining thereto (determined on the basis of the Currency in which such
Securities and Coupons appertaining thereto are then specified as payable at Stated
Maturity) which through the scheduled payment of principal and interest in respect
thereof in accordance with their terms will provide, not later than one day before
the due date of any payment of principal of (and premium, if any) and

36

 

interest, if any, on such Securities and any Coupons appertaining thereto,
money in an amount, or

     3. a combination thereof,

     in any case, in an amount, sufficient, without consideration of any reinvestment of
such principal and interest, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the Trustee,
to pay and discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, the principal of (and premium, if any) and interest, if any,
on such Outstanding Securities and any Coupons appertaining thereto on the Stated Maturity
of such principal or installment of principal or interest on the day on which such payments
are due and payable in accordance with the terms of this Indenture and of such Securities
and any Coupons appertaining thereto.

     (b) Such defeasance or covenant defeasance shall not result in a breach or violation
of, or constitute a default under, this Indenture or any other material agreement or
instrument to which the Company or any of the Guarantors is a party or by which it is bound.

     (c) No Event of Default or event which with notice or lapse of time or both would
become an Event of Default with respect to such Securities and any Coupons appertaining
thereto shall have occurred and be continuing on the date of such deposit and, with respect
to defeasance only, at any time during the period ending on the 91st day after the date of
such deposit (it being understood that this condition shall not be deemed satisfied until
the expiration of such period).

     (d) In the case of an election under clause (2) of this Section 402, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has
received from the Internal Revenue Service a letter ruling, or there has been published by
the Internal Revenue Service a Revenue Ruling, or (ii) since the date of execution of this
Indenture, there has been a change in the applicable Federal income tax law, in either case
to the effect that, and based thereon such opinion shall confirm that, the Holders of such
Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain
or loss for Federal income tax purposes as a result of such defeasance and will be subject
to Federal income tax on the same amounts, in the same manner and at the same times as would
have been the case if such defeasance had not occurred.

     (e) In the case of an election under clause (3) of this Section 402, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such
Outstanding Securities and any Coupons appertaining thereto will not recognize income, gain
or loss for Federal income tax purposes as a result of such covenant defeasance and will be
subject to Federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such covenant defeasance had not occurred.

37

 

     (f) The Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant
defeasance under clause (2) or (3) of this Section 402 (as the case may be) have been
complied with.

     (g) Notwithstanding any other provisions of this Section 402(4), such defeasance or
covenant defeasance shall be effected in compliance with any additional or substitute terms,
conditions or limitations which may be imposed on the Company or the Guarantors in
connection therewith pursuant to Section 301.

     (5) Subject to the provisions of the last paragraph of Section 1003, all money and Government
Obligations (or other property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 402(5) and Section 403, the “Trustee”) pursuant to clause (4) of Section 402 in respect of
any Outstanding Securities of any series and any Coupons appertaining thereto shall be held in
trust and applied by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine,
to the Holders of such Securities and any Coupons appertaining thereto of all sums due and to
become due thereon in respect of principal (and premium, if any) and interest and Additional
Amounts, if any, but such money need not be segregated from other funds except to the extent
required by law.

     Unless otherwise specified in or pursuant to this Indenture or any Security, if, after a
deposit referred to in Section 402(4)(a) has been made, (a) the Holder of a Security in respect of
which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of
such Security to receive payment in a Currency other than that in which the deposit pursuant to
Section 402(4)(a) has been made in respect of such Security, or (b) a Conversion Event occurs in
respect of the Foreign Currency in which the deposit pursuant to Section 402(4)(a) has been made,
the indebtedness represented by such Security and any Coupons appertaining thereto, and any
Securities Guarantee, shall be deemed to have been, and will be, fully discharged and satisfied
through the payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes due out of the
proceeds yielded by converting (from time to time as specified below in the case of any such
election) the amount or other property deposited in respect of such Security into the Currency in
which such Security becomes payable as a result of such election or Conversion Event based on (x)
in the case of payments made pursuant to clause (a) above, the applicable market exchange rate for
such Currency in effect on the second Business Day prior to each payment date, or (y) with respect
to a Conversion Event, the applicable market exchange rate for such Foreign Currency in effect (as
nearly as feasible) at the time of the Conversion Event.

     The Company shall pay and indemnify the Trustee against any tax, fee or other charge, imposed
on or assessed against the Government Obligations deposited pursuant to this Section 402 or the
principal or interest received in respect thereof other than any such tax, fee or other charge
which by law is for the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

38

 

     Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay
to the Company from time to time upon Company Request any money or Government Obligations (or other
property and any proceeds therefrom) held by it as provided in clause (4) of this Section 402
which, in the opinion of a nationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, are in excess of the amount thereof
which would then be required to be deposited to effect a defeasance or covenant defeasance, as
applicable, in accordance with this Section 402.

     Section 403. Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1003, all money and Government
Obligations deposited with the Trustee pursuant to Section 401 or 402 shall be held in trust and
applied by it, in accordance with the provisions of the Securities, the Coupons 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,
premium, interest and Additional Amounts for whose payment such money has or Government Obligations
have been deposited with or received by the Trustee; but such money and Government Obligations need
not be segregated from other funds except to the extent required by law.

     Section 404. Reinstatement.

     If the Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, then the
obligations under this Indenture and such Securities and Securities Guarantees from which the
Company and the Guarantors have been discharged or released pursuant to this Article shall be
revived and reinstated as though no deposit has occurred pursuant to this Article with respect to
such Securities and Securities Guarantees, until such time as the Trustee or Paying Agent is
permitted to apply all money held in trust pursuant to this Article with respect to such Securities
in accordance with this Article; provided, however, that if the Company or, if applicable, any of
the Guarantors make any payment of principal of or any premium or interest on any such Security or
Securities Guarantee following reinstatement of its obligations, the Company and the Guarantors
shall be subrogated to the rights (if any) of the Holders of such Securities to receive such
payment from the money so held in trust.

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 be 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 such event is specifically deleted or modified in or pursuant to the

39

 

supplemental indenture, Board Resolution or Officers’ Certificate establishing the terms of
such Series pursuant to this Indenture:

     (1) failure to pay any interest on or any Additional Amounts payable in respect of any
Security of such series when such interest becomes or such Additional Amounts become due and
payable, and continuance of such default for a period of 30 days; or

     (2) failure to pay the principal of or any premium on any Security of such series when it
becomes due and payable at either its Maturity or, if applicable, at 12:00 noon on the Business Day

     If an Event of Default with respect to Securities of any series at the time Outstanding (other
than an Event of Default specified in clause (6) or (7) of Section 501) occurs and is continuing,
then the Trustee or the Holders of not less than 25% in principal amount of the Outstanding
Securities of such series may declare the principal of all the Securities of such series, or such
lesser amount as may be provided for in the Securities of such series, to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders),
and upon any such declaration such principal or such lesser amount shall become immediately due and
payable.

41

 

     If an Event of Default specified in clause (6) or (7) of Section 501 occurs, all unpaid
principal of and accrued interest on the Outstanding Securities of that series (or such lesser
amount as may be provided for in the Securities of such series) shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

     At any time after Securities of any series have been accelerated and before a judgment or
decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of not less than a majority in principal amount of the Outstanding Securities
of such series, by written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

     (1) the Company or, if applicable, one or more of the Guarantors has paid or deposited with
the Trustee a sum of money sufficient to pay

     (a) all overdue installments of any interest on and Additional Amounts with respect to
all Securities of such series and any Coupon appertaining thereto,

     (b) the principal of and any premium on any Securities of such series which have become
due otherwise than by such declaration of acceleration and interest thereon and any

interest upon overdue installments of any interest and Additional Amounts at the rate or
rates borne by or provided for in such Securities, and

     (d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel and all other
amounts due the Trustee under Section 606; and

     (2) all Events of Default with respect to Securities of such series, other than the
non-payment of the principal of, any premium and interest on, and any Additional Amounts with
respect to Securities of such series which shall have become due solely by such declaration of
acceleration, shall 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) there is a failure to pay any installment of interest on or any Additional Amounts with
respect to any Security or any Coupon appertaining thereto when such interest or Additional Amounts
shall have become due and payable and such default continues for a period of 30 days, or

42

 

     (2) there is a failure to pay the principal of or any premium on any Security at its Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders
of such Securities and any Coupons appertaining thereto, the whole amount of money then due and
payable with respect to such Securities and any Coupons appertaining thereto, with interest upon
the overdue principal, any premium and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate
or rates borne by or provided for in such Securities, and, in addition thereto, such further amount
of money 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 to the Trustee under Section 606.

     If the Company fails to pay the money it is required to pay the Trustee pursuant to the
preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as
trustee of an express trust, may institute a judicial proceeding for the collection of the money so
due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the
same against the Company or, if applicable, the Guarantors or any other obligor upon such
Securities and any Coupons appertaining thereto and collect the monies adjudged or decreed to be
payable in the manner provided by law out of the property of the Company or, if applicable, the
Guarantors or any other obligor upon such Securities and any Coupons appertaining thereto, 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 and any Coupons appertaining thereto 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 such
Securities or in aid of the exercise of any power granted herein or therein, 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, if applicable, any Guarantor or any other obligor upon the Securities or the property
of the Company, any Guarantor or such other obligor or their creditors, the Trustee (irrespective
of whether the principal of the Securities shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the
Company or, if applicable, the Guarantors for the payment of any overdue principal, premium,
interest or Additional Amounts) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

     (1) to file and prove a claim for the whole amount, or such lesser amount as may be provided
for in the Securities of such series, of the principal and any premium, interest and Additional
Amounts owing and unpaid in respect of the Securities and any Coupons appertaining thereto and to
file such other papers or documents as may be necessary or advisable in order to

43

 

have the claims of the Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents or counsel) and of the Holders of Securities
or any Coupons allowed in such judicial proceeding, and

     (2) 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 606.

     Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder of a Security or any Coupon any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or Coupons or, if applicable, the
Securities Guarantee or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder of a Security or any Coupon in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in
bankruptcy or similar official and be a member of a creditors’ committee or other similar
committee.

     Section 505. Trustee May Enforce Claims without Possession of Securities or Coupons.

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

     Section 506. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be applied in the following
order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal, or any premium, interest or Additional Amounts, upon presentation of the
Securities or Coupons, or both, as the case may be, 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 and any predecessor Trustee under Section
606;

     SECOND: To the payment of the amounts then due and unpaid upon the Securities and any Coupons
for principal and any premium, interest and Additional Amounts in respect of

44

 

which or for the benefit of which such money has been collected, ratably, without preference
or priority of any kind, according to the aggregate amounts due and payable on such Securities and
Coupons for principal and any premium, interest and Additional Amounts, respectively;

     THIRD: The balance, if any, to the Person or Persons entitled thereto.

     Section 507. Limitations on Suits.

     No Holder of any Security of any series or any Coupons appertaining thereto shall have any
right to institute any proceeding, judicial or otherwise, with respect to this Indenture
(including, if applicable, the Securities Guarantee), or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless

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

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

     (3) such Holder or Holders have offered to the Trustee reasonable indemnity 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 such series;

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

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

     Notwithstanding any other provision in this Indenture, the Holder of any Security or Coupon
shall have the right, which is absolute and unconditional, to receive payment of the principal of,
any premium and (subject to Sections 305 and 307) interest on, and any Additional Amounts with
respect to such Security or payment of such Coupon, as the case may be, on the respective Stated
Maturity or Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of such Holder if
provided in or pursuant to this Indenture, on the date such repayment is due, or in the case of a
Change in Control, or as to any Change in Control Purchase Notice given timely, on the

45

 

Change in Control Purchase Date) and to institute suit for the enforcement of any such
payment, and such right shall not be impaired without the consent of such Holder.

     Section 509. Restoration of Rights and Remedies.

     If the Trustee or any Holder of a Security or a Coupon 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 Guarantors, if any, the Trustee and each such Holder shall,
subject to any determination in such proceeding, be restored severally and respectively to their
former positions hereunder, and thereafter all rights and remedies of the Trustee and each such
Holder 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 or Coupons in the last paragraph of Section 306, no right or
remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security
or a Coupon is intended to be exclusive of any other right or remedy, and every right and remedy,
to the extent permitted by law, shall 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, to the extent permitted by
law, 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 Security or Coupon to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy
given by this Article or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such
Holder, as the case may be.

     Section 512. Control by Holders of Securities.

     Subject to Section 601(5), the Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust or power conferred
on the Trustee with respect to the Securities of such series and any Coupons appertaining thereto,
provided that

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

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

46

 

     (3) such direction is not unduly prejudicial to the rights of the other Holders of Securities
of such series not joining in such action.

     Section 513. Waiver of Past Defaults.

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

     (1) in the payment of the principal of, any premium or interest on, or any Additional Amounts
with respect to, any Security of such series or any Coupons appertaining thereto, or

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

     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. Waiver of Stay or Extension Laws.

     Each of the Company and the Guarantors covenants that (to the extent that it may lawfully do
so) 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 each of the
Company and the Guarantors expressly waives (to the extent that it may lawfully do so) 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.

     Section 515. 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 any
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; but the provisions of this Section 515 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in principal amount of Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest,
if any, on or Additional Amounts, if any, with respect to any Security on or after the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on or after the
Redemption Date, in the case of repayment, on or after the date for repayment and, in the

47

 

case of Change of Control, on or after the date for payment of the Change of Control Purchase
Price).

to be genuine and to have been signed or presented by the proper party or parties;

     (2) any request or direction of the Company or a Guarantor mentioned herein shall be
sufficiently evidenced by a Company Request or a Company Order (in each case, other than delivery

and delivery pursuant to Section 303 which shall be sufficiently evidenced as provided therein) and
any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution;

     (3) whenever in the administration of this Indenture the Trustee shall deem it desirable that

protected in withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the best interest of the Holders of
Securities and Coupons of such series. For the purpose of this Section, the term “default” means

the Guarantors.

     Section 606. Compensation and Reimbursement.

     The Company agrees:

for all reasonable expenses, disbursements and advances incurred or made by the Trustee in

premium or interest on or any Additional Amounts with respect to particular Securities or any
Coupons appertaining thereto.

insolvency law. “Trustee” for purposes of this Section 606 shall include any predecessor Trustee
but the negligence or bad faith of any Trustee shall not affect the rights of any other Trustee
under this Section 606.

50

 

     The Company’s obligations under this Section 606 and any lien hereunder shall survive the
resignation or removal of any Trustee, the discharge of the Company’s obligations pursuant to
Article Four of this Indenture and the termination of this Indenture.

     Section 608. Resignation and Removal; Appointment of Successor.

     (1) No resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of appointment by the
successor Trustee pursuant to Section 609.

     (2) 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 609 shall not have been delivered to the Trustee within 30 days after

of the Holders of a majority in principal amount of the Outstanding Securities of such series,

request therefor by the Company or any Holder of a Security of such series who has been a

after written request therefor by the Company or any such Holder, or

     (c) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or

Trustee with respect to all Securities or the Securities of such series, or (ii) subject to Section

51

 

315(e) of the Trust Indenture Act, any Holder of a Security who has been a bona fide Holder of a

shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor
Trustee or Trustees with respect to the 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

forthwith upon its acceptance of such appointment in accordance with the applicable requirements of
Section 609, become the successor Trustee with respect to the Securities of such series and to that

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 the Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are issued as Bearer
Securities, by publishing notice of such event once in an Authorized Newspaper in each Place of
Payment located outside the United States. 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

     Section 609. Acceptance of Appointment by Successor.

     (1) Upon the appointment hereunder of any successor Trustee with respect to all Securities,
such successor Trustee so appointed shall execute, acknowledge and deliver to the Company, the
Guarantors (if applicable) and 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 hereunder of the retiring Trustee; but, on the request of the

one or more (but not all) series, the Company, the Guarantors (if applicable), the retiring Trustee
and such successor Trustee 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, such successor Trustee

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, 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 that no Trustee
shall be responsible for any notice given to, or received by, or any act or failure to act on the
part of any other Trustee hereunder, and, upon the execution and delivery of such supplemental
indenture, the resignation or removal of the retiring Trustee shall become effective to the extent
provided therein, such retiring Trustee shall have no further responsibility for the exercise of
rights and powers or for the performance of the duties and obligations vested in the Trustee under
this Indenture with respect to the Securities of that or those series to which the appointment of
such successor Trustee relates other than as hereinafter expressly set forth, 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 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,

successor relates and subject to Section 1003 shall duly assign, transfer and deliver to such
successor Trustee, to the extent contemplated by such supplemental indenture, the property and
money held by such retiring Trustee hereunder with respect to the Securities of that or those

provided for in Section 606.

     (3) Upon request of any Person appointed hereunder as a successor Trustee, the Company and, if
applicable, the Guarantors 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 (1) or (2) of this Section, as the case may be.

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

     Section 610. 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 of the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, without
the execution or filing of any paper or any further act on the part of any of the parties hereto.
In case any Securities shall have been authenticated but not delivered by the Trustee then in
office, any successor by merger, conversion or consolidation to such authenticating Trustee may
adopt such authentication and deliver the Securities so authenticated with the same effect as if
such successor Trustee had itself authenticated such Securities.

     Section 611. Appointment of Authenticating Agent.

     The Trustee may appoint one or more Authenticating Agents acceptable to the Company with
respect to one or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of that or those series issued upon original issue, exchange,
registration of transfer, partial redemption or partial repayment 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, if applicable, the
Guarantors and, except as provided in or pursuant to this Indenture, shall at all times be a
corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture
qualified under the Trust Indenture Act, is authorized under applicable law and by its charter to
act as an Authenticating Agent and has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section,
it shall resign immediately in the manner and with the effect specified in this Section.

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

     An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee
and the Company and, if applicable, the Guarantors. The Trustee may at any time terminate the
agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and
the Company and, if applicable, the Guarantors. Upon receiving such a notice of resignation or upon
such a termination, or in case at any time such Authenticating

54

 

Agent shall cease to be eligible in accordance with the provisions of this Section, the
Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and,
if applicable, the Guarantors and shall (i) mail written notice of such appointment by first-class
mail, postage prepaid, to all Holders of Registered Securities, if any, of the series with respect
to which such Authenticating Agent shall serve, as their names and addresses appear in the Security
Register, and (ii) if Securities of the series are issued as Bearer Securities, publish notice of
such appointment at least once in an Authorized Newspaper in the place where such successor
Authenticating Agent has its principal office if such office is located outside the United States.
Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

     The Company agrees to pay each Authenticating Agent from time to time reasonable compensation
for its services under this Section. If the Trustee makes such payments, it shall be entitled to be
reimbursed for such payments, subject to the provisions of Section 606.

     The provisions of Sections 308, 603 and 604 shall be applicable to each Authenticating Agent.

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

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

of such series.

ARTICLE TEN

COVENANTS

     Section 1001. Payment of Principal, any Premium, Interest and Additional Amounts.

     The Company covenants and agrees for the benefit of the Holders of the Securities of each
series that it will duly and punctually pay the principal of, any premium and interest on and any
Additional Amounts with respect to the Securities of such series in accordance with the terms
thereof, any Coupons appertaining thereto and this Indenture. Any interest due on any Bearer
Security on or before the Maturity thereof, and any Additional Amounts payable with respect to such
interest, shall be payable only upon presentation and surrender of the Coupons appertaining thereto
for such interest as they severally mature.

     Section 1002. Maintenance of Office or Agency.

     The Company and, if applicable, the Guarantors shall maintain in each Place of Payment for any
series of Securities an Office or Agency where Securities of such series, and the Securities
Guarantee with respect thereto (but not Bearer Securities, except as otherwise provided below,
unless such Place of Payment is located outside the United States) may be presented or surrendered
for payment, where Securities of such series may be surrendered for registration of transfer or
exchange, and where notices and demands to or upon the Company or, if applicable, the Guarantors in
respect of the Securities of such series relating thereto and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company and, if applicable, the
Guarantors shall maintain, subject to any laws or regulations applicable thereto, an Office or
Agency in a Place of Payment for such series which is located outside the United States where
Securities of such series and any Coupons appertaining thereto, and the Securities Guarantee with
respect thereto, may be presented and surrendered for payment; provided, however, that if the
Securities of such series are listed on The Stock Exchange of the United Kingdom and the Republic
of Ireland or the Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company and, if applicable, the Guarantors
shall maintain a Paying Agent in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Securities of such series are listed on such
exchange. The Company and, if applicable, the Guarantors will give prompt written notice to the
Trustee of the location, and any change in the location, of such Office or Agency. If at any time
the Company and, if applicable, the Guarantors shall fail to maintain any such required Office or
Agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee,
except that Bearer Securities of such series and any Coupons appertaining thereto, and the
Securities Guarantee with respect thereto, may be presented and surrendered for payment at the
place specified for the purpose with respect to such Securities as provided in or pursuant to this
Indenture, and the Company and, if applicable, the Guarantors, hereby appoint the Trustee as their
agent to receive all such presentations, surrenders, notices and demands.

     Except as otherwise provided in or pursuant to this Indenture, no payment of principal,
premium, interest or Additional Amounts with respect to Bearer Securities shall be made at any

62

 

Office or Agency in the United States or by check mailed to any address in the United States
or by transfer to an account maintained with a bank located in the United States; provided,
however, if amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts with respect to any
such Security, or the Securities Guarantee with respect thereto, may be made at the Corporate Trust
Office of the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of such principal,
premium, interest or Additional Amounts at all offices outside the United States maintained for
such purpose by the Company and, if applicable, the Guarantors in accordance with this Indenture is
illegal or effectively precluded by exchange controls or other similar restrictions.

     The Company and, if applicable, the Guarantors may also from time to time designate one or
more other Offices or Agencies where the Securities of one or more series, and the Securities
Guarantee endorsed thereon, 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 or, if applicable, the Guarantors of their
obligation to maintain an Office or Agency in each Place of Payment for Securities of any series
for such purposes. The Company and, if applicable, the Guarantors shall 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. Unless otherwise provided in or pursuant to this Indenture, the Company
and, if applicable, the Guarantors hereby designate as the Place of Payment for each series of
Securities and the Securities Guarantee endorsed thereon, the Borough of Manhattan, The City of New
York, and initially appoints the Corporate Trust Office of the Trustee as the Office or Agency of
the Company and, if applicable, the Guarantors, in the Borough of Manhattan, The City of New York
for such purpose. The Company and, if applicable, the Guarantors may subsequently appoint a
different Office or Agency in the Borough of Manhattan, The City of New York for the Securities of
any series, and the Securities Guarantee endorsed thereon.

     Unless otherwise specified with respect to any Securities pursuant to Section 301, if and so
long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be
payable in a Foreign Currency, or so long as it is required under any other provision of this
Indenture, then the Company and, if applicable, the Guarantors will maintain with respect to each
such series of Securities, or as so required, at least one exchange rate agent.

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

     If the Company shall at any time act as its own Paying Agent with respect to any series of
Securities, it shall, on or before each due date of the principal of, any premium or interest on or
Additional Amounts with respect to any of the Securities of such series, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum in the Currency or Currencies in which
the Securities of such series are payable (except as otherwise specified pursuant to Section 301
for the Securities of such series) sufficient to pay the principal or any premium, interest or
Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and shall promptly notify the Trustee of its action or failure so
to act.

63

 

     Whenever the Company shall have one or more Paying Agents for any series of Securities, it
shall, on or prior to each due date of the principal of, any premium or interest on or any
Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a
sum (in the Currency or Currencies described in the preceding paragraph) sufficient to pay the
principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in
trust for the benefit of the Persons entitled thereto, 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 shall cause each Paying Agent for any series of Securities other than the Trustee
to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the
Trustee, subject to the provisions of this Section, that such Paying Agent shall:

     (1) hold all sums held by it for the payment of the principal of, any premium or interest on
or any Additional Amounts with respect to Securities of such series in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as
provided in or pursuant to this Indenture;

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

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

     The Company and, if applicable, the Guarantors 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 terms as those upon which such sums were
held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

     Except as otherwise provided herein or pursuant hereto, 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, any
premium or interest on or any Additional Amounts with respect to any Security of any series or any
Coupon appertaining thereto and remaining unclaimed for two years after such principal or any such
premium or interest or any such Additional Amounts shall have become due and payable shall be paid
to the Company on Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security or any Coupon appertaining thereto shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the Company cause to be
published once, in an Authorized Newspaper in each Place of Payment for such series or to be mailed
to Holders of Registered Securities of such series, or both, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than 30 days from the
date of such

64

 

publication or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance
of such money then remaining will be repaid to the Company.

     Section 1004. Additional Amounts.

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

     Except as otherwise provided in or pursuant to this Indenture or the Securities of the
applicable series, 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 such series of Securities
(or if the Securities of such series shall not bear interest prior to Maturity, the first day on
which a payment of principal is made), and at least 10 days prior to each date of payment of
principal or interest if there has been any change with respect to the matters set forth in the
below-mentioned Officers’ Certificate, the Company or, if applicable, the Guarantors, as the case
may be, shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than
the Trustee, an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of and premium, if any, or interest on the Securities of
such series shall be made to Holders of Securities of such series or the Coupons appertaining
thereto who are United States Aliens without withholding for or on account of any tax, assessment
or other governmental charge described in the Securities of such 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 or Coupons, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of
such Securities. Each of the Company and, if applicable, the Guarantors 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.

     Section 1005. Limitation on Liens.

     Nothing in this Indenture or in the Securities shall in any way restrict or prevent the
Company, any Guarantor or any Subsidiary from issuing, assuming, guaranteeing or otherwise
incurring any indebtedness; provided, however, that none of the Company, any Guarantor nor any
Subsidiary shall issue, assume or guaranty any notes, bonds, debentures or other similar

65

 

evidences of indebtedness for money borrowed secured by any Lien on any asset now owned or
hereafter acquired by it without making effective provision whereby any and all Securities then or
thereafter outstanding shall be secured by a Lien equally and ratably with any and all other
obligations thereby secured, so long as any such obligations shall be so secured. Notwithstanding
the foregoing, the Company, any Guarantor or any Subsidiary, without so securing the Securities,
may issue, assume or guaranty indebtedness secured by the following Liens:

     (a) Liens existing on the date of this Indenture or provided for under the terms of
agreements existing on the date hereof;

     (b) Liens on property to secure (i) all or any portion of the cost of exploration,
production, gathering, processing, marketing, drilling or development of such property, (ii)
all or any portion of the cost of acquiring, constructing, altering, improving or repairing
any property or assets, real or personal, or improvements used in connection with such
property, and (iii) indebtedness incurred by the Company, any Guarantor or any Subsidiary to
provide funds for the activities set forth in clauses (i) and (ii) above;

     (c) Liens which secure indebtedness owing by a Subsidiary to the Company or any
Guarantor or to one or more other Subsidiaries, or to the Company or any Guarantor and one
or more other Subsidiaries;

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

     (e) Liens on any property securing (i) indebtedness incurred in connection with the
construction, installation or financing of pollution control or abatement facilities or
other forms of industrial revenue bond financing, (ii) indebtedness issued or guaranteed by
the United States, any state or any department, agency or instrumentality of either or (iii)
indebtedness issued or guaranteed by (Y) a foreign government, any state or any department,
agency or instrumentality of either or (Z) an international finance agency or any division
or department thereof, including the World Bank, the International Finance Corp. and the
Multilateral Investment Guarantee Agency;

     (f) any Lien extending, renewing or replacing (or successive extensions, renewals or
replacements of) any Lien of the type set forth in paragraph (a) through (e) above, which
Lien exists on the date of this Indenture;

     (g) any Ordinary Course Lien (as defined below) arising, and only so long as
continuing, in the ordinary course of the Company’s business; or

     (h) Liens which secure Limited Recourse Indebtedness.

     Notwithstanding the foregoing, the Company, any Guarantor and any one or more Subsidiaries may
issue, assume or guaranty the following indebtedness secured by Liens on assets without regard to
indebtedness in any aggregate principal amount which, together with the aggregate outstanding
principal amount of all other indebtedness of the Company, any Guarantor and its Subsidiaries so
secured (excluding indebtedness secured by the permitted Liens described above), and the aggregate
amount of Sale/Leaseback Transaction obligations which would

66

 

otherwise be subject to the provisions of Section 1006, does not at the time such indebtedness
is incurred exceed 10% of the Company’s Consolidated Net Worth as shown on the most recent audited
consolidated balance sheet of the Company and its Subsidiaries.

     Notwithstanding the foregoing, nothing in this Section 1005 shall be deemed to prohibit or
otherwise limit the following types of transactions:

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

     (2) the granting of Liens required by any contract or statute in order to permit the Company
or a Subsidiary to perform any contract or subcontract made by it with or at the request of the
United States government or any foreign government or international finance agency, any state or
any department thereof, or any agency or instrumentality thereof, or to secure partial, progress,
advance or other payments to the Company or any Subsidiary by any such entity pursuant to the
provisions of any contract or statute.

     “Lien” shall mean, with respect to any asset, any mortgage, lien, pledge, security interest or
encumbrances of any kind in respect of such asset, whether or not filed, recorded or otherwise
perfected under applicable law. The Company, any Guarantor or any Subsidiary shall be deemed to own
subject to a Lien any asset which it has acquired or holds subject to the interest of a vendor or
lessor under any conditional sale agreement, capital lease or other title retention agreement
relating to such asset. The right of set-off, whether by operation of law or by contract, does not
constitute a Lien unless there is a related obligation to maintain a deposit of cash or other
assets in respect of which such right of set-off may be exercised.

     “Ordinary Course Lien” shall mean:

     (a) Liens for taxes, assessments or governmental changes or levies on the property of
the Company, any Guarantor or any Subsidiary if the same shall not at the time be delinquent
or thereafter can be paid without penalty, or are being contested in good faith and by
appropriate proceedings and for which adequate reserves in accordance with generally
accepted accounting principles shall have been set aside on the books of the Company of, if
applicable, a Guarantor;

     (b) Liens imposed by law, such as carriers’, warehousemen’s, landlords’ and mechanics’
liens and other similar liens arising in the ordinary course of business which secure
obligations not more than 60 days past due or which are being contested in good faith by
appropriate proceedings and for which adequate reserves in accordance with generally
accepted accounting principles shall have been set aside on the books of the Company or, if
applicable, a Guarantor;

67

 

     (c) Liens arising out of pledges or deposits under worker’s compensation laws,
unemployment insurance, old age pensions, or other social security or retirement benefits,
or similar legislation;

     (d) Utility easements, building restrictions and such other encumbrances or charges
against real property as are of a nature generally existing with respect to properties of a
similar character and which do not in any material way affect the marketability of the same
or interfere with the use thereof in the business of the Company or, if applicable, the
Guarantors, or any Subsidiary, as the case may be;

     (e) Liens arising under operating agreements or similar agreements in respect of
obligations which are not yet due or which are being contested in good faith by appropriate
proceedings;

     (f) Liens reserved in oil, gas and/or mineral leases for bonus or rental payments and
for compliance with the terms of such leases;

     (g) Liens pursuant to partnership agreements, oil, gas and/or mineral leases,
farm-out-agreements, division orders, contracts for the sale, purchase, exchange, or
processing of oil, gas and/or other hydrocarbons, unitization and pooling declarations and
agreements, operating agreements, development agreements, area of mutual interest
agreements, forward sale agreements, oil and gas delivery obligations, and other agreements
which are customary in the oil, gas and other mineral exploration, development and
production business and in the business of processing of gas and gas condensate production
of the extraction of products therefrom;

     (h) Liens on personal property (excluding the capital stock or indebtedness of any
Subsidiary) securing indebtedness maturing not more than one year from the date of its
creation; and

     (i) Liens relating to a judgment or other court-ordered award or settlement as to which
the Company or, if applicable, a Guarantor has not exhausted its appellate rights.

     “Consolidated Net Worth” means the consolidated stockholders’ equity of the Company,
determined in accordance with generally accepted accounting principles.

     Section 1006. Limitation on Sale/Leaseback Transactions.

     None of the Company, any Guarantor nor any Subsidiary will enter into any Sale/Leaseback
Transaction with any Person (other than the Company, any Guarantor or a Subsidiary) providing for a
term of more than three years unless:

     (a) the Company, such Guarantor or such Subsidiary would be permitted, pursuant to the
terms of Section 1005, to incur indebtedness in an aggregate principal amount equal to or
exceeding the value of the Sale/Leaseback Transaction secured by a Lien on the property
subject to such Sale/Leaseback Transaction;

68

 

     (b) since the date of this Indenture and within a period commencing six months prior to
the Sale/Leaseback Transaction and ending six months after the consummation thereof, the
Company, such Guarantor or such Subsidiary expends for any property (including amounts
expended for the acquisition, exploration, drilling or development thereof, or for
additions, alterations, improvements or repairs thereto) an amount up to the net proceeds of
such Sale/Leaseback Transaction, and the Company or, if applicable, such Guarantor, as the
case may be, elects to designate such amount as a credit against such Sale/Leaseback
Transaction (with any amount of such net proceeds not being so designated to be applied as
set forth in paragraph (c) below); or

     (c) the Company or, if applicable, such Guarantor, as the case may be, during or
immediately after the expiration of the 12 month period following the consummation of the
Sale/Leaseback Transaction, applies to the voluntary retirement, redemption or defeasance of
the Securities and its other Senior Indebtedness an amount equal to the greater of (i) the
net proceeds of the Sale/Leaseback Transaction and (ii) the fair value, in the opinion of
the Board of Directors of the Company or, if applicable, such Guarantor, as the case may be,
of the subject property of the Sale/Leaseback Transaction at the time of such transaction
(adjusted, in either case, to reflect the remaining term of the lease and any amount applied
pursuant to paragraph (b) above), less an amount equal to the principal amount of other
Senior Indebtedness voluntarily retired by the Company or, if applicable, any Guarantor
during such 12-month period.

     “Sale/Leaseback Transaction” means any arrangement providing for the leasing to the Company,
any Guarantor or any Subsidiary by any Person (other than the Company, any Guarantor or a
Subsidiary) of any property which has been, or is to be, sold or transferred by the Company, any
Guarantor or such Subsidiary to such Person or to any Person (other than the Company or a
Subsidiary) to which funds have been or are to be advanced by such Person on the security of the
leased property, except with respect to any lease that secures or relates to obligations issued by
or on behalf of (a) the United States, any state or any department, agency or instrumentality of
either, (b) a foreign government, any state or any department agency or instrumentality of either,
or (c) an international finance agency or any division or department thereof, including the World
Bank, the International Finance Corp. and the Multilateral Investment Guarantee Agency, in
connection with the financing of the cost of construction, improvement or equipping of such
property.

     Section 1007. Corporate Existence.

     Subject to Articles Eight and Fifteen, the Company and, if applicable, each of the Guarantors
shall do or cause to be done all things necessary to preserve and keep in full force and effect its
corporate existence and that of each Subsidiary and their respective rights (charter and statutory)
and franchises; provided, however, that the foregoing shall not obligate the Company and, if
applicable, each Guarantor or any Subsidiary to preserve any such right or franchise if the
Company, any Guarantor or any Subsidiary shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company or such Guarantor or such Subsidiary, as
the case may be.

     Section 1008. Waiver of Certain Covenants.

69

 

     The Company or, if applicable, the Guarantors may omit in any particular instance to comply
with any term, provision or condition set forth in Sections 1005, 1006 or 1007 with respect to the
Securities of any series if before the time for such compliance the Holders of at least a majority
in principal amount of the Outstanding Securities of such series, by Act of such Holders, either
shall waive such compliance in such instance or generally shall have waived compliance with such
term, provision or condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and, if applicable, the Guarantors and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and effect.

     Section 1009. Company Statement as to Compliance; Notice of Certain Defaults.

     (1) The Company and, if any Securities of a series to which Article Sixteen has been made
applicable are Outstanding, each Guarantor shall deliver to the Trustee, within 120 days after the
end of each fiscal year beginning with the first fiscal year during which one or more Securities
are Outstanding, a written statement (which need not be contained in or accompanied by an Officers’
Certificate) signed by the principal executive officer, the principal financial officer or the
principal accounting officer of the Company and, if applicable, such Guarantor, stating that

     (a) a review of the activities of the Company or, if applicable, such Guarantor, as the
case may be, during such year and of its performance under this Indenture has been made
under his or her supervision, and

     (b) to the best of his or her knowledge, based on such review, (a) the Company or, if
applicable, such Guarantor, as the case may be, has complied with all the conditions and
covenants imposed on it under this Indenture throughout such year, or, if there has been a
default in the fulfillment of any such condition or covenant, specifying each such default
known to him or her and the nature and status thereof, and (b) no event has occurred and is
continuing which is, or after notice or lapse of time or both would become, an Event of

known to him and the nature and status thereof.

     (2) The Company and, if any Securities of a series to which Article Sixteen has been made
applicable are Outstanding, each Guarantor shall deliver to the Trustee, within five days after the
occurrence thereof, written notice of any Event of Default or any event which after notice or lapse
of time or both would become an Event of Default.

ARTICLE ELEVEN

REDEMPTION OF SECURITIES

     Section 1101. Applicability of Article.

     Redemption of Securities of any series at the option of the Company as permitted or required
by the terms of such Securities shall be made in accordance with the terms of such Securities and
(except as otherwise provided herein or pursuant hereto) this Article.

70

 

     Section 1102. Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution or an Officer’s Certificate. In case of any redemption at the election of the
Company of (a) less than all of the Securities of any series or (b) all of the Securities of any
series, with the same issue date, interest rate or formula, Stated Maturity and other terms, the
Company shall, at least 60 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.

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

     If less than all of the Securities of any series with the same issue date, interest rate or
formula, Stated Maturity and other terms are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from
the Outstanding Securities of such series not previously called for redemption, by such method as
the Trustee shall deem fair and appropriate and which may provide for the selection for redemption
of portions of the principal amount of Registered Securities of such series; provided, however,
that no such partial redemption shall reduce the portion of the principal amount of a Registered
Security of such series not redeemed to less than the minimum denomination for a Security of such
series established herein or pursuant hereto.

     The Trustee shall promptly notify the Company and the Security Registrar (if other than
itself) 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 of such Securities which has been or is
to be redeemed.

     Section 1104. Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 106, not less than 30
nor more than 60 days prior to the Redemption Date, unless a shorter period is specified in the
Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by
mailing in the manner herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect
the validity of the proceedings for the redemption of any other Securities or portion thereof.

     Any notice that is mailed to the Holder of any Registered Securities in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not such Holder
receives the notice.

     All notices of redemption shall state:

     (1) the Redemption Date,

71

 

     (2) the Redemption Price,

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

     (4) in case any Security is to be redeemed in part only, the notice which relates to such
Security shall state that on and after the Redemption Date, upon surrender of such Security, the
Holder of such Security will receive, without charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed,

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

     (6) the place or places where such Securities, together (in the case of Bearer Securities)
with all Coupons appertaining thereto, if any, maturing after the Redemption Date, are to be
surrendered for payment of the Redemption Price and any accrued interest and Additional Amounts
pertaining thereto,

     (7) that, unless otherwise specified in such notice, Bearer Securities of any series, if any,
surrendered for redemption must be accompanied by all Coupons maturing subsequent to the date fixed
for redemption or the amount of any such missing Coupon or Coupons will be deducted from the
Redemption Price, unless security or indemnity satisfactory to the Company, the Trustee and any
Paying Agent is furnished,

     (8) if Bearer Securities of any series are to be redeemed and any Registered Securities of
such series are not to be redeemed, and if such Bearer Securities may be exchanged for Registered
Securities not subject to redemption on the Redemption Date pursuant to Section 305 or otherwise,
the last date, as determined by the Company, on which such exchanges may be made,

     (9) the CUSIP number or the Euroclear or the Cedel reference numbers of such Securities, if
any (or any other numbers used by a Depository to identify such Securities).

     A notice of redemption mailed as contemplated by Section 106 need not identify particular
Registered 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 prior to any Redemption Date, the Company shall deposit, with respect to the Securities
of any series called for redemption pursuant to Section 1104, 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 in the applicable Currency sufficient to pay

72

 

the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date,
unless otherwise specified pursuant to Section 301 or in the Securities of such series) any accrued
interest on and Additional Amounts with respect thereto, all such Securities or portions thereof
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 and the Coupons for such interest
appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall
be void. Upon surrender of any such Security for redemption in accordance with said notice,
together with all Coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except as otherwise
provided in or pursuant to this Indenture or the Bearer Securities of such series, installments of
interest on Bearer Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 1002), and provided,
further, that, except as otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities 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 Regular Record
Dates therefor according to their terms and the provisions of Section 307.

     If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant
Coupons maturing after the Redemption Date, such Security may be paid after deducting from the
Redemption Price an amount equal to the face amount of all such missing Coupons, or the surrender
of such missing Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or
any Paying Agent any such missing Coupon in respect of which a deduction shall have been made from
the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such Security located
outside of the United States except as otherwise provided in Section 1002.

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

     Section 1107. Securities Redeemed in Part.

73

 

     Any Registered Security which is to be redeemed only in part shall be surrendered at any
Office or Agency for such Security (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 Registered Security or Securities of the same series, containing
identical terms and provisions, 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. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository or other Depository
for such Security in global form as shall be specified in the Company Order with respect thereto to
the Trustee, without service charge, a new Security in global form in a denomination equal to and
in exchange for the unredeemed portion of the principal of the Security in global form so
surrendered.

ARTICLE TWELVE

REPAYMENT AT THE OPTION OF HOLDERS

     Section 1201. Applicability of Article.

     Securities of any series which are repayable at the option of the Holders thereof before their
Stated Maturity shall be repaid in accordance with the terms of the Securities of such series. The
repayment of any principal amount of Securities pursuant to such option of the Holder to require
repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented by such Securities
unless and until the Company, at its option, shall deliver or surrender the same to the Trustee
with a directive that such Securities be cancelled. Notwithstanding anything to the contrary
contained in this Section 1201, in connection with any repayment of Securities, the Company may
arrange for the purchase of any Securities by an agreement with one or more investment bankers or
other purchasers to purchase such Securities by paying to the Holders of such Securities on or
before the close of business on the repayment date an amount not less than the repayment price
payable by the Company on repayment of such Securities, and the obligation of the Company to pay
the repayment price of such Securities shall be satisfied and discharged to the extent such payment
is so paid by such purchasers.

ARTICLE THIRTEEN

SECURITIES IN FOREIGN CURRENCIES

     Section 1301. Applicability of Article.

     Whenever this Indenture provides for (i) any action by, or the determination of any of the
rights of, Holders of Securities of any series in which not all of such Securities are denominated

provision to the contrary in the form of Security of any particular series or pursuant to this
Indenture or the Securities, any amount in respect of any Security denominated in a Currency

74

 

other than Dollars shall be treated for any such action or distribution as that amount of
Dollars that could be obtained for such amount on such reasonable basis of exchange and as of the
record date with respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable record date, such
other date reasonably proximate to the date of such action, determination of rights or
distribution) as the Company or, if applicable, the Guarantors may specify in a written notice to
the Trustee or, in the absence of such written notice, as the Trustee may determine.

Outstanding Securities of any series shall have requested the Trustee to call a meeting of the
Holders of Securities of such series for any purpose specified in Section 1401, by written request
setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee
shall not have mailed notice of or made the first publication of the notice of such meeting within
21 days after receipt of such request (whichever shall be required pursuant to Section 106) or
shall not thereafter proceed to cause the meeting to be held as provided herein, then the Company

principal amount of the Outstanding Securities of a series, the Persons entitled to vote 66-2/3% in
principal amount of the Outstanding Securities of such series shall constitute a quorum. In the
absence of a quorum within 30 minutes after the time appointed for any such meeting, the meeting

other case the meeting may be adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any
such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less
than 10 days as determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in
Section 1402(1), except that such notice need be given only once not less than five days prior to
the date on which the meeting is scheduled to be reconvened. Notice of the reconvening of an
adjourned meeting shall state expressly the percentage, as provided above, of the principal amount

the affirmative vote of the Holders of a majority in principal amount of the Outstanding Securities
of that series; provided, however, that, except as limited by the proviso to Section 902, any

principal amount of the Outstanding Securities of a series may be adopted at a meeting or an
adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative
vote of the Holders of such specified percentage in principal amount of the Outstanding Securities
of such series.

     Any resolution passed or decision taken at any meeting of Holders of Securities of any series
duly held in accordance with this Section shall be binding on all the Holders of Securities

76

 

of such series and the Coupons appertaining thereto, whether or not such Holders were present
or represented at the meeting.

     Section 1405. Determination of Voting Rights; Conduct and Adjournment of Meetings.

     (1) Notwithstanding any other provisions of this Indenture, the Trustee may make such
reasonable regulations as it may deem advisable for any meeting of Holders of Securities of such
series in regard to proof of the holding of Securities of such series and of the appointment of
proxies and in regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise
permitted or required by any such regulations, the holding of Securities shall be proved in the
manner specified in Section 104 and the appointment of any proxy shall be proved in the manner
specified in Section 104 or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to certify to the holding
of Bearer Securities. Such regulations may provide that written instruments appointing proxies,
regular on their face, may be presumed valid and genuine without the proof specified in Section 104
or other proof.

     (2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
meeting, unless the meeting shall have been called by the Company or, if applicable, any Guarantor
or by Holders of Securities as provided in Section 1402(2), in which case the Company or the
Holders of Securities of the series calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall
be elected by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

     (3) At any meeting, each Holder of a Security of such series or proxy shall be entitled to one
vote for each $1,000 principal amount of Securities of such series held or represented by him;
provided, however, that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a Security of such
series or proxy.

     (4) Any meeting of Holders of Securities of any series duly called pursuant to Section 1402 at
which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority
in principal amount of the Outstanding Securities of such series represented at the meeting; and
the meeting may be held as so adjourned without further notice.

     Section 1406. Counting Votes and Recording Action of Meetings.

     The vote upon any resolution submitted to any meeting of Holders of Securities of any series
shall be by written ballots on which shall be subscribed the signatures of the Holders of
Securities of such series or of their representatives by proxy and the principal amounts and serial
numbers of the Outstanding Securities of such series held or represented by them. The permanent
chairman of the meeting shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the secretary of the

77

 

meeting their verified written reports in triplicate of all votes cast at the meeting. A
record, at least in triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be attached to said record
the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits
by one or more persons having knowledge of the facts setting forth a copy of the notice of the
meeting and showing that said notice was given as provided in Section 1402 and, if applicable,
Section 1404. Each copy shall be signed and verified by the affidavits of the permanent chairman
and secretary of the meeting and one such copy shall be delivered to the Company, another to each
of the Guarantors, if applicable, and another to the Trustee to be preserved by the Trustee, the
latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified
shall be conclusive evidence of the matters therein stated.

under the Exchange Act of 1934, or any successor provision) of either
(A) 50% or more of the shares of Common Stock then outstanding or (B) 50% or more of the voting power of the Voting

of this Section 1501(a), a person shall not be deemed the beneficial owner of (1) any
securities tendered pursuant to a tender offer or exchange offer made by or on behalf of
such person, or its Affiliates or Associates, until such tendered securities are accepted
for purchase or exchange thereunder, or (2) any securities in respect of which beneficial
ownership by such person arises solely as a result of a revocable proxy delivered in
response to a proxy or consent solicitation that is made pursuant to, and in accordance
with, the Exchange Act

78

 

of 1934 and the applicable rules and regulations thereunder and is not then reportable
on Schedule 13D (or any successor schedule, form or report) under the Exchange Act of 1934.

     (b) There shall be consummated any sale, transfer, lease or conveyance of all or
substantially all of the properties and assets of the Company to any other Corporation or
Corporations or other person or persons (other than a Subsidiary of the Company).

     (c) There shall be consummated any consolidation of the Company with or merger of the
Company with or into any other Person (whether or not affiliated with the Company) in which
the Company is not the sole surviving or continuing corporation or
pursuant to which the shares of Common Stock outstanding immediately prior to the consummation of such
consolidation or merger are converted into cash, securities or other property, other than a
consolidation or merger in which the holders of shares of Common Stock receive, directly or
indirectly, (A) 75% or more of the common stock of the sole surviving or continuing
Corporation outstanding immediately following the consummation of such consolidation or
merger and (B) securities representing 75% or more of the combined voting power of the
Voting Stock of the sole surviving or continuing corporation outstanding immediately
following the consummation thereof of such consolidation or merger.

     “Exchange Act of 1934” shall mean the Securities Exchange Act of 1934, as amended.

     “Associate” shall have the meaning ascribed to such term in Rule 12b-2 under the Exchange Act
of 1934, as in effect on the date hereof.

     (2) Within 15 Business Days after the occurrence of a Change in Control, the Company shall
mail a written notice of Change in Control by first-class mail to the Trustee and to each Holder
(and to beneficial owners as required by applicable law, including, without limitation, Rule 13e-4)
and shall cause a copy of such notice to be published at least once in an Authorized Newspaper
located in New York City and, if any Securities are then listed on any stock exchange located
outside the United States, in an Authorized Newspaper in such city as the stock exchange so
requires. The notice shall include or transmit a form of Change in Control Purchase Notice (as
described below) to be completed by the Holder and shall state:

     (a) the events causing a Change in Control and the date of such Change in Control;

     (b) the date by which the Change in Control Purchase Notice pursuant to this Section
1601 must be given;

     (c) the Change in Control Purchase Date;

     (d) the Change in Control Purchase Price;

     (e) the name and address of the Trustee and the Office or Agency;

79

 

     (f) that the Securities must be surrendered to the Trustee or the Office or Agency to
collect payment;

     (g) that the Change in Control Purchase Price for any Security as to which a Change in
Control Purchase Notice has been duly given and not withdrawn will be paid promptly
following the later of the Change in Control Purchase Date or the time of surrender of such
Security as described in (f);

     (h) the procedures the Holder must follow to exercise rights under this Section 1501(1)
and a brief description of those rights; and

     (i) the procedures for withdrawing a Change in Control Purchase Notice.

     (3) A Holder may exercise its rights specified in Section 1501(1) upon delivery of a written
notice of purchase (a “Change in Control Purchase Notice”) to the Trustee or to the Office or

will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof;
and

     (c) that such Security or Securities shall be purchased on the Change in Control
Purchase Date pursuant to the terms and conditions specified in the Securities.

     The delivery of the Security, by hand or by registered mail prior to, on or after the Change
in Control Purchase Date (together with all necessary endorsements), to the Trustee or to the
Office or Agency shall be a condition precedent to the obligation of the Company to pay to the
Holder the Change in Control Purchase Price therefor; provided, however, that such Change in
Control Purchase Price shall be so paid pursuant to this Section 1501 only if the Security so
delivered to the Trustee or such Office or Agency shall conform in all respects to the description
thereof set forth in the related Change in Control Purchase Notice.

     Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee or to
the Office or Agency, the Change in Control Purchase Notice contemplated by this Section 1501(3)
shall have the right to withdraw such Change in Control Purchase Notice at any time prior to or on
the Change in Control Purchase Date by delivery of a written notice of withdrawal to the Trustee or
to such office or agency in accordance with Section 1502.

     Section 1502. Effect of Change in Control Purchase Notice.

     Upon receipt by the Company of the Change in Control Purchase Notice specified in Section
1501(3), the Holder of the Security in respect of which such Change in Control Purchase Notice was
given shall (unless such Change in Control Purchase Notice is withdrawn as specified in the
following paragraph) thereafter be entitled to receive solely the Change in

80

 

Control Purchase Price with respect to such Security. Such Change in Control Purchase Price
shall be paid to such Holder promptly following the later of (x) the Change in Control Purchase
Date, as the case may be, with respect to such Security (provided the conditions in Section
1501(3), as applicable, have been satisfied) and (y) the time of delivery of such Security to the
Trustee or to the Office or Agency by the Holder thereof in the manner required by Section 1501(3),
as applicable.

     A Change in Control Purchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the office of the Trustee or to the Office or Agency at any time prior to
the close of business on the Change in Control Purchase Date, specifying:

     (1) the certificate number or numbers of the Security or Securities in respect of which such
notice of withdrawal is being submitted;

     (2) the principal amount of the Security or Securities with respect to which such notice of
withdrawal is being submitted; and

     (3) the principal amount, if any, of such Security or Securities which remains subject to the
original Change in Control Purchase Notice, and which has been and will be delivered for purchase
by the Company.

     There shall be no purchase of any Securities pursuant to Section 1501 if there has occurred
and in continuing an Event of Default (other than a default in the payment of the Change in Control
Purchase Price).

     Section 1503. Deposit of Change in Control Purchase Price.

     Prior to 12:00 Noon (local time in The City of New York) on the Business Day following the
Change in Control Purchase Date, the Company shall deposit with the Trustee (or, if the Company or
a Subsidiary or an Affiliate of either of them is acting as Paying Agent, shall segregate and hold
in trust as provided in Section 1003) an amount of cash in immediately available funds or
securities, if expressly permitted hereunder, sufficient to pay the aggregate Change in Control
Purchase Price of all the Securities or portions thereof which are to be purchased. If a deposit is
made with the Trustee of the aforesaid amount of cash or securities, the Securities or portions
thereof with respect to which a Change in Control Purchase Notice has been delivered and not
validly withdrawn shall become due and payable as of the Business Day following the applicable
Change in Control Purchase Date, and on and after such date interest payable in respect of such
Securities shall cease and all other rights of the Holders thereof shall terminate, other than the
right to receive the Change in Control Purchase Price upon delivery of such Securities to the
Trustee.

     Section 1504. Covenant to Comply With Securities Laws Upon Purchase of Securities.

     In connection with any purchase of securities under Section 1601 hereof, the Company shall (a)
comply with Rule 13e-4 under the Exchange Act of 1934, if applicable, (b) file the related Schedule
13E-4 (or any successor schedule, form or report) under the Exchange Act of 1934, if applicable,
and (c) otherwise comply with all Federal and state securities laws regulating the purchase of the
Securities (including positions of the Commission under applicable no-action

81

 

letters) so as to permit the rights and obligation under Section 1501 to be exercised in the
time and in the manner specified in Section 1501 and 1502.

     Section 1505. Repayment to the Company.

     The Trustee shall return to the Company any cash, together with interest or dividends, if any,
thereon (subject to the provisions of Section 605) held by it for the payment of the Change in
Control Purchase Price of the Securities that remain unclaimed as provided in the Securities;
provided, however, that to the extent the aggregate amount of cash deposited by the Company
pursuant to Section 1503 exceeds the aggregate Change in Control Purchase Price of the Securities
or portions thereof to be purchased, then promptly after the Change in Control Purchase Date, the
Trustee shall return any such excess to the Company together with interest or dividends, if any,
thereon (subject to the provisions of Section 605).

to be made punctually when and as the same shall become due and payable, whether at the Stated

     The Guarantors hereby agree that any amounts to be paid by them hereunder shall be paid
without deduction or withholding for or on account of any and all present or future tax, duty,

state, political subdivision or taxing authority, the Guarantors shall pay such additional
amount in respect of principal, premium, if any, and interest, if any, as may be necessary in order
that the net amounts paid to the Holder of a Security or the Trustee on behalf of the Holder of
such Security, as the case may be, pursuant to this Securities Guarantee after such deduction or
withholding shall not be less than the amount provided for in such Security to be then due and
payable, except that no such additional amount shall be payable in respect of any Security to any
Holder (a) who is subject to such tax, duty, assessment or governmental charge in respect of such
Security by reason of his being connected with the United States otherwise than merely by the
holding or ownership of such Security, or (b) who is not dealing at arm’s length with the
Guarantors (within the meaning of the Internal Revenue Code as amended from time to time).

     The Guarantors hereby agree that their obligations hereunder shall be as if they were
principal debtor and not merely surety, and shall be absolute and unconditional, irrespective of
the validity, regularity or enforceability of any Security or this Indenture, the absence of any
action to enforce the same, any waiver or consent by the Holder of such Security or by the Trustee
with respect to any provisions thereof or of this Indenture, the obtaining of any judgment against
the Company or any action to enforce the same or any other circumstances that might otherwise
constitute a legal or equitable discharge or defense of a guarantor. The Guarantors hereby waive
the benefits of division and discussion, diligence, presentment, demand of payment, filing of
claims with a court in the event of merger, insolvency or bankruptcy of the Company, any right to
require a proceeding first against the Company, protest or notice with respect to any Security or
the indebtedness evidenced thereby and all demands whatsoever, and covenant that no guarantee
(including any Securities Guarantee endorsed on a Security) will be discharged in respect of any
Security except by complete performance of the obligations contained in such Security and in the
Securities Guarantee. The Guarantors hereby agree that, in the event of a default in payment of
principal (or premium, if any) or interest, if any, on or Additional Amounts with respect to any
Security, or a default in any payment referred to therein, legal proceedings may be instituted by
the Trustee on behalf of, or by, the Holder of such Security, on the terms and conditions set forth
in this Indenture, directly against the Guarantors to enforce the Securities Guarantee without
first proceeding against the Company.

     The Guarantors shall be subrogated to all rights of the Holders of the Securities of a
particular series against the Company in respect of any amounts paid by the Guarantors on account
of such Securities pursuant to the provisions of the Securities Guarantee or this Indenture;
provided, however, that the Guarantors 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, any premium and
interest on, and Additional Amounts with respect to, all Securities of such series issued hereunder
shall have been paid in full.

     Section 1602. Execution and Delivery of Securities Guarantees.

     The Securities Guarantees to be endorsed on the Securities of each series shall include the
terms of the guarantee set forth in, established by or pursuant to a Board Resolution, an Officer’s
Certificate or in one or more indentures supplemental hereto (except that references to premium and
interest need be included only if any premium or interest, respectively, is provided for in the
terms of such series) and any other terms that may be set forth in, established by or pursuant to a
Board Resolution, an Officer’s Certificate or in one or more indentures supplemental hereto with

83

 

respect to such series. The Guarantors hereby agree to execute the Securities Guarantees, in
a form set forth in, established by or pursuant to a Board Resolution, an Officer’s Certificate or
in one or more indentures supplemental hereto, to be endorsed on each Security authenticated and
delivered by the Trustee.

     The Securities Guarantees shall be executed on behalf of the Guarantors by the Chairman of the
Board, Vice Chairman of the Board, President or a Vice President of each Guarantor, under its
respective corporate seal reproduced thereon attested by its respective Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities Guarantees may be
manual or facsimile.

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

     The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall
constitute due delivery of the Securities Guarantee endorsed thereon on behalf of the Guarantors.
The Guarantors hereby agree that the Securities Guarantee set forth in, established by or pursuant
to a Board Resolution, an Officer’s Certificate or in one or more indentures supplemental hereto
and in this Article shall remain in full force and effect notwithstanding any failure to endorse a
Securities Guarantee on any Security.

     The Securities Guarantee shall continue to be effective or be reinstated, as the case may be,
if at any time payment on any Security, in whole or in part, is rescinded or must otherwise be
restored to the Company or the Guarantors upon the bankruptcy, liquidation or reorganization of the
Company or any of the Guarantors or otherwise.
