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 made, 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, 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 1506.

     Without limiting the generality of this Section 104, unless otherwise provided in or pursuant
to this Indenture, a Holder, including a 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 or the Securities to be made, given or taken by Holders, and a 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 Depository’s standing instructions and customary
practices.

     (2) 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

11

 

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.

     (3) 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.

     (4) 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 Securities, if such
certificate or affidavit is deemed by the Company and 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.

     (5) 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.

     (6) 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.

12

 

     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,

     (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, 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

13

 

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 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.

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.

     Section 111. Separability Clause.

     In case any provision in this Indenture, any Security or any Coupon shall be invalid, illegal
or unenforceable, the validity, legality and enforceability of the remaining provisions shall not,
to the fullest extent permitted by law, 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
successors hereunder and the Holders of Securities or Coupons, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

14

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.

     Unless otherwise specified in or pursuant to this Indenture or any Securities, in any case
where any Interest Payment Date, Stated Maturity or Maturity of, or any other day on which a
payment is due with respect to, any Security shall be a day which is not a Business Day 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 or in the Board Resolution, Officers’
Certificate or supplemental indenture establishing the terms of any Security that specifically
states that such provision shall apply in lieu hereof) payment need not be made at such Place of
Payment on such date, but such payment may be made on the next succeeding day that is a Business
Day at such Place of Payment with the same force and effect as if made on the Interest Payment
Date, at the Stated Maturity or Maturity or on any such other payment date, as the case may be, 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, Stated Maturity, Maturity or other payment date, as the case may
be, to the next succeeding Business Day.

     Section 115. Counterparts.

all of which shall constitute but one and the same instrument.

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) its obligations under this Indenture to make payments
in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery
pursuant to any judgment (whether or not entered in accordance with 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

15

 

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. The provisions of this Section 116
shall not be applicable with respect to any payment due on a Security which is payable in Dollars.

     In the event that (i) the terms of any Security or Coupon appertaining thereto established in
or pursuant to this Indenture permit the Company or any Holder thereof to extend the date on which
any payment of principal of, or premium, if any, or interest, if any, on, or Additional Amounts, if
any, with respect to such Security or Coupon is due and payable and (ii) the due date for any such

     No recourse under or upon any obligation, covenant or agreement contained in this Indenture,
or in any Security, or because of any indebtedness evidenced thereby, shall be had against any
past, present or future stockholder, employee, officer or director, as such, of the Company or of
any predecessor or successor, either directly or through the Company or any predecessor or
successor, under any rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of the Securities by the Holders and as part of the
consideration for the issue of the Securities.

     Section 119. Waiver of Jury Trial.

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

of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of
God, and interruptions, loss or malfunctions of utilities, communications or computer (software and
hardware) services; it being understood that the Trustee shall use reasonable efforts which are
consistent with accepted practices in the banking industry to resume performance as soon as
practicable under the circumstances.

issued pursuant to this Indenture shall be in the form established by or pursuant to a Board
Resolution and set forth in an Officers’ Certificate, or established in one or more indentures
supplemental hereto, shall have such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by or pursuant to this Indenture or any indenture
supplemental hereto and may have such letters, numbers or other marks of identification and such
legends or endorsements placed thereon as may, consistently herewith, be determined by the officer

Coupon.

     Unless otherwise provided in or pursuant to this Indenture or any Securities, the Securities
shall be issuable in registered form without Coupons.

     Definitive Securities and definitive Coupons shall be printed, lithographed or engraved or
produced by any combination of these methods on a steel engraved border or steel engraved borders
or may be produced in any other manner, all as determined by the officer of the Company executing
such Securities or Coupons, as evidenced by the execution of such Securities or Coupons.

     Section 202. Form of Trustee’s Certificate of Authentication.

     Subject to Section 611, the Trustee’s certificate of authentication shall be in substantially
the following form:

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

                                                            ,

as Trustee

	 	 	 	 	 
	 	 	 
	 	By:  	
 	 
	 	 	Authorized Signatory 	 
	 	 	 	 
	 

     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 global form. If Securities of a series shall be issuable in temporary or
permanent 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

17

 

(or such lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon or reflected on the books and records of the Trustee 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 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 pursuant to Section 301 with respect to such Security 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 global form in the manner and upon instructions given by the Person or
Persons specified therein or pursuant to Section 301 with respect to such Security 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 foregoing provisions of
this paragraph, in the event a global Security is exchangeable for definitive Securities as
provided in Section 305, then, unless otherwise provided in or pursuant to this Indenture with
respect to the Securities of such series, the Trustee shall deliver and redeliver such global
Security to the extent necessary to effect such exchanges, shall endorse such global Security to
reflect any decrease in the principal amount thereto resulting from such exchanges and shall take
such other actions, all as contemplated by Section 305.

     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.

than in the manner provided in this Indenture;

     (25) whether and to what extent the Securities shall be guaranteed by any Person or
Persons; and

     (26) any other terms of such Securities and any deletions from or modifications or
additions to this Indenture in respect of such Securities.

     All Securities of any one series and all Coupons, if any, appertaining to Bearer Securities of
such series shall be substantially identical except as to Currency of payments due thereunder,
denomination and the rate of interest, or method of determining the rate of interest, if any,
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. The terms of the Securities of any series may provide, without limitation, that the
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 Board Resolution, Officers’
Certificate or supplemental indenture, as the case may be, pertaining to such series of Securities
(telephonic instructions to be promptly confirmed in writing by such person) and that such persons
are authorized to determine, consistent with such Board Resolution, Officers’ Certificate or
supplemental indenture, such terms and conditions of the Securities of such series as are

22

 

specified in such Board Resolution, Officers’ Certificate or supplemental indenture. All
Securities of any one series need not be issued at the same time and, if so provided by the Company
as contemplated by this Section 301, a series may be reopened from time to time without the consent
of any Holders 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 Resolution 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, its President or one of
its Vice Presidents and by its Treasurer, its Secretary or one of its Assistant Secretaries and may
(but need not) have its corporate seal or a facsimile thereof reproduced thereon. Coupons shall be
executed on behalf of the Company by the Chairman, the President or any Vice President 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, to the fullest extent
permitted by law, 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, an Opinion of Counsel to the following effect,

23

 

which Opinion of Counsel may contain such assumptions, qualifications and limitations as such
counsel shall deem appropriate:

     (a) the form or forms and terms of such Securities and Coupons, if any, have been
established in conformity with Sections 201 and 301 of this Indenture;

     (b) all conditions precedent set forth in Sections 201, 301 and 303 of this Indenture
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 (if applicable), executed 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 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).

     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 at the time of issuance of each Security, but such
opinion, with such modifications as counsel shall deem appropriate, 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 signatories. 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 or as may otherwise be provided in or pursuant to this

24

 

Indenture, 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.

     Except in the case of temporary Securities in global form, which shall be exchanged in
accordance with the provisions set forth in this Indenture or the provisions established pursuant
to Section 301, if temporary Securities are issued, the Company shall cause definitive Securities
to be prepared without unreasonable delay. Except as otherwise provided in or pursuant to this
Indenture, 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. Except as otherwise
provided in or pursuant to this Indenture, 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 initial Security Registrar for each series of
Securities shall be as specified in the penultimate paragraph of Section 1002. The Company shall
have the right to remove and replace from time to time the Security Registrar for any series

25

 

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. 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.

     Except as otherwise provided in or pursuant to this Indenture, 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.

     Except as otherwise provided in or pursuant to this Indenture, 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 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

26

 

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.

     Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture,
the global Securities of any series shall be exchangeable for definitive certificated Securities of
such series only if (i) the Depository for such global Securities notifies the Company that it is
unwilling or unable to continue as a Depository for such global Securities or at any time the
Depository for such global Securities ceases to be a clearing agency registered as such under the
Exchange Act, if so required by applicable law or regulation, and no successor Depository for such
Securities shall have been appointed within 90 days of such notification or of the Company becoming
aware of the Depository’s ceasing to be so registered, as the case may be, (ii) the Company, in its
sole discretion, determines that the Securities of such series shall no longer be represented by
one or more global Securities and executes and delivers to the Trustee a Company Order to the
effect that such global Securities shall be so exchangeable, or (iii) an Event of Default has
occurred and is continuing with respect to such 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 paragraph, 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 Depository (or its custodian) as shall be specified in the
Company Order with respect thereto (which the Company agrees to deliver), and in accordance with
instructions given to the Trustee and the Depository (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

27

 

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, and which
shall be in such denominations and, in the case of Registered Securities, registered in such names,
as shall be specified by the Depository, 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 its custodian) or such
other Depository (or its custodian) referred to above in accordance with the instructions of the
Company referred to above, and the Trustee shall endorse such global Security to reflect the
decrease in the principal amount thereof resulting from such exchange. 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, 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 of Securities, or
any redemption or repayment of Securities, or any conversion or exchange of Securities for other
types of securities or property, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section 304, 905 or 1107, upon
repayment or repurchase in part of any Registered Security pursuant to Article Thirteen, or upon
surrender in part of any Registered Security for conversion or exchange into

28

 

Common Stock or other securities or property pursuant to its terms, in each case not involving
any transfer.

     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 terms and of 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, or portion thereof, so selected for redemption, except in the case of any
Registered 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 terms and of the same series, provided that such Registered Security shall be
simultaneously 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
pursuant to Article Thirteen and not withdrawn, except the portion, if any, of such Security not to
be so repaid.

     The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance
with any restrictions on transfer imposed under this Indenture or under applicable law with respect
to any transfer of any interest in any Security (including any transfers between or among
Depositary participants or beneficial owners of interests in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are expressly required
by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the
same to determine substantial compliance as to form with the express requirements hereof.

     Neither the Trustee nor any Paying Agent shall have any responsibility for any actions taken
or not taken by the Depositary.

     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 acquired by a
bona fide purchaser, the Company shall execute and, upon the Company’s request

29

 

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 payment of 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 any 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 (to the extent lawful) 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 therefor and before
the opening of business at such Office or Agency on the next succeeding

30

 

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

31

 

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 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 of America.

     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, 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, 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

32

 

ownership interests of a global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

     Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, any
Paying Agent or the Security Registrar from giving effect to any written certification, proxy or
other authorization furnished by the applicable Depository, as a Holder, with respect to a global
Security or impair, as between such Depository and the owners of beneficial interests in such
global Security, the operation of customary practices governing the exercise of the rights of such
Depository (or its nominee) as the Holder of such global Security.

     Section 309. Cancellation.

     All Securities and Coupons surrendered for payment, redemption, registration of transfer,
exchange or conversion or for credit against any sinking fund payment 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 disposed of in
accordance with its procedures for the disposition of cancelled securities and the Trustee shall
deliver to the Company a certificate of such disposition, 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 the Securities of any
series, 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.

     Unless, pursuant to Section 301, the provisions of this Section 401 shall not be applicable

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

33

 

     (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 1106, and (iv) Securities and Coupons of such series
for whose payment money 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, if
applicable, 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, to the extent that the Securities of
such series provide for the payment of Additional Amounts thereon and the amount of
any such Additional Amounts which are or will be payable with respect to the
Securities of such series is at the time of deposit determinable by the Company (in
the exercise by the Company of its reasonable discretion), 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

34

 

     (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 Outstanding 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, 404, 1002, 1003 and, if applicable to the Securities of such series, 1004
(including, without limitation, 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)), any rights of Holders of the Securities
of such series (unless otherwise provided pursuant to Section 301 with respect to the Securities of
such series) to require the Company to repurchase or repay, and the obligations of the Company to
repurchase or repay, such Securities at the option of the Holders pursuant to Article Thirteen
hereof, and any rights of Holders of the Securities of such series (unless otherwise provided
pursuant to Section 301 with respect to the Securities of such series) to convert or exchange, and
the obligations of the Company to convert or exchange, such Securities into Common Stock or other
securities or property, 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, at any time, with respect to the
Securities of or within such series 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. Unless otherwise
specified pursuant to Section 301 with respect to the Securities of any series, defeasance under
clause (2) of this Section 402 and covenant defeasance under clause (3) of this Section 402 may be
effected only with respect to all, and not less than all, of the Outstanding Securities of any
series. To the extent that the terms of any Security or Coupon appertaining thereto established in
or pursuant to this Indenture permit the Company or any Holder thereof to extend the date on which
any payment of principal of, or premium, if any, or interest, if any, on, or Additional Amounts, if
any, with respect to such Security or Coupon is due

35

 

and payable, then unless otherwise provided pursuant to Section 301, the right to extend such
date shall terminate upon defeasance or covenant defeasance, as the case may be.

     (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) through (iv) of this paragraph, 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 (except as provided in clause (ii) below) from the trust fund described in clause
(4)(a) of this Section 402 and as more fully set forth in this Section 402 and 403, 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, (ii) the obligations of the Company and the Trustee with respect to such Securities under
Sections 305, 306, 1002, 1003 and, if applicable to the Securities of such series, 1004 (including,
without limitation, 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 clause (4)(a) of this Section 402)), any rights of Holders of such Securities
(unless otherwise provided pursuant to Section 301 with respect to the Securities of such series)
to require the Company to repurchase or repay, and the obligations of the Company to repurchase or
repay, such Securities at the option of the Holders pursuant to Article Thirteen hereof, and any
rights of Holders of such Securities (unless otherwise provided pursuant to Section 301 with
respect to the Securities of such series) to convert or exchange, and the obligations of the
Company to convert or exchange, such Securities into Common Stock or other securities or property,
(iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this
Section 402 and Sections 403 and 404. The Company may exercise its option under this
Section 402(2) notwithstanding the prior exercise of its option under Section 402(3) 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 clauses (ii) and (iii) of Section 1005 and under Sections 1006, 1007, and 1008 and any other
covenant applicable to such Securities with respect to such Securities and any Coupons appertaining
thereto shall cease to be applicable to such Securities 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

36

 

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 any 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(4) or 501(8) 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, if such defeasance or covenant defeasance is to be effected in compliance with
subsection (f) below, on the relevant Redemption Date, as the case may be, 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 or, if such defeasance or covenant defeasance is to
be effected in compliance with subsection (f) below, on the relevant Redemption Date, as the
case may be) 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, (y) the principal of (and premium, if any) and interest, if any, on,
and, to the extent that such Securities provide for the payment of Additional Amounts
thereon and the amount of any such Additional Amounts which are or will be payable with
respect to the Securities of such series is at the time of deposit determinable by the
Company (in the exercise by the Company of its reasonable discretion), any Additional
Amounts with respect to, such Outstanding Securities and any Coupons appertaining thereto on
the Stated Maturity of such principal or installment of principal or interest or the
applicable Redemption Date, as the case may be, and (z) any mandatory sinking fund payments
or analogous payments applicable to such Outstanding Securities and any

37

 

Coupons appertaining thereto 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 Subsidiary 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, solely in
the case of defeasance under Section 402(2), no Event of Default with respect to such
Securities and any Coupons appertaining thereto under clause (5) or (6) of Section 501 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 under clause (5) or (6) of
Section 501 shall have occurred and be continuing at any time during the period ending on
and including the 91st day after the date of such deposit (it being understood that this
condition to defeasance under Section 402(2) shall not be deemed satisfied until the
expiration of such period).

     (d) In the case of defeasance pursuant to Section 402(2), the Company shall have
delivered to the Trustee an opinion of independent counsel reasonably acceptable to the
Trustee stating that (x) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling, or (y) since the date of this Indenture there has been a
change in applicable federal income tax law, in either case to the effect that, and based
thereon such opinion of independent counsel 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; or, in the case of covenant
defeasance pursuant to Section 402(3), the Company shall have delivered to the Trustee an
opinion of independent counsel reasonably acceptable to the Trustee 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.

     (e) 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, as the case may be, under this Indenture have been complied with.

     (f) If the monies or Government Obligations or combination thereof, as the case may be,
deposited under clause (a) above are sufficient to pay the principal of, and premium, if
any, and interest, if any, on and, to the extent provided in such clause (a), Additional
Amounts with respect to, such Securities provided such Securities are redeemed on a
particular Redemption Date, the Company shall have given the Trustee

38

 

irrevocable instructions to redeem such Securities on such date and to provide notice
of such redemption to Holders as provided in or pursuant to this Indenture.

     (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)(a) 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 (other than the Company or any Subsidiary or Affiliate of the Company acting as 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 Securities, 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.

39

 

     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)(a) 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 other qualifying trustee appointed pursuant to Section 402(4)(a)) or any
Paying Agent is unable to apply any moneys or Government Obligations deposited pursuant to
Section 401(1) or 402(4)(a) to pay any principal of or premium, if any, or interest, if any, on or
Additional Amounts, if any, with respect to the Securities of any series by reason of any legal
proceeding or any order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the Company’s obligations under this Indenture and
the Securities of such series shall be revived and reinstated as though no such deposit had
occurred, until such time as the Trustee (or other qualifying trustee) or Paying Agent is permitted
to apply all such moneys and Government Obligations to pay the principal of and premium, if any,
and interest, if any, on and Additional Amounts, if any, in respect of the Securities of such
series as contemplated by Sections 401 or 402 as the case may be, and Section 403; provided,
however, that if the Company makes any payment of the principal of or premium, if any, or interest
if any, on or Additional Amounts, if any, in respect of the Securities of such series following the
reinstatement of its obligations as aforesaid, the Company shall be subrogated to the rights of the
Holders of such Securities to receive such payment from the funds held by the Trustee (or other
qualifying trustee) or Paying Agent.

     (8) any other Event of Default provided in or pursuant to this Indenture with respect

     Section 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in clause (5) or (6) of
Section 501) with respect to Securities of any series occurs and is continuing, then either the
Trustee or the Holders of not less than 25% in aggregate 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, and accrued and unpaid
interest, if any, thereon 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

42

 

principal or such lesser amount, as the case may be, and such accrued and unpaid interest
shall become immediately due and payable. If an Event of Default specified in clause (5) or (6) of
Section 501 with respect to the Securities of any series occurs, then the principal of all of the
Securities of such series, or such lesser amount as may be provided for in the Securities of such
series, and accrued and unpaid interest, if any, thereon 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 the Securities of such 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 aggregate 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
(or, to the extent that the terms of the Securities of such series established pursuant to
Section 301 expressly provide for payment to be made in shares of Common Stock or other
securities or property, shares of Common Stock or other securities or property, together
with cash in lieu of fractional shares or securities, sufficient to pay)

     (a) all overdue installments of any interest on any Securities of such series
and any Coupons appertaining thereto which have become due otherwise than by such
declaration of acceleration and any Additional Amounts with respect 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 any
Additional Amounts with respect thereto and, to the extent permitted by applicable
law, interest thereon at the rate or respective rates, as the case may be, provided
for in or with respect to such Securities, or, if no such rate or rates are so
provided, at the rate or respective rates, as the case may be, of interest borne by
such Securities,

     (c) to the extent permitted by applicable law, interest upon installments of
any interest, if any, which have become due otherwise than by such declaration of
acceleration and any Additional Amounts with respect thereto at the rate or
respective rates, as the case may be, provided for in or with respect to such
Securities, or, if no such rate or rates are so provided, at the rate or respective
rates, as the case may be, of interest borne by 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

43

 

     (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) default is made in the payment of any interest on, or any Additional Amounts
payable in respect of any interest on, any Security or any Coupon appertaining thereto when
such interest or Additional Amounts, as the case may be, shall have become due and payable
and such default continues for a period of 30 days, or

     (2) default is made in the payment of any principal of or premium, if any, on, or any
Additional Amounts payable in respect of any principal of or premium, if any, on, any
Security at its Maturity, or

     (3) default is made in the deposit of any sinking fund payment when due,

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 permitted by applicable law, upon any overdue
installments of interest and Additional Amounts at the rate or respective rates, as the case may
be, provided for or with respect to such Securities or, if no such rate or rates are so provided,
at the rate or respective rates, as the case may be, of interest borne by 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

44

 

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.

     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,

45

 

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 with respect to the Securities of
any series shall be applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any premium, interest or
Additional Amounts, upon presentation of such Securities or the Coupons, if any, appertaining
thereto, 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:

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;

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

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

46

 

     (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, if any, and (subject to Sections 305 and 307) interest, if any, on and any Additional
Amounts with respect to such Security or 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 pursuant to Article Thirteen hereof
at the option of such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and, in the case of any Security which is convertible into or exchangeable for
other securities or property, to convert or exchange, as the case may be, such Security in
accordance with its terms, and to institute suit for the enforcement of any such payment and any
such right to convert or exchange, 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.

     To the extent permitted by applicable law and 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

47

 

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, to the extent permitted by applicable
law, 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, to the extent permitted by applicable law, 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.

     The Holders of a majority in aggregate 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.

Securities of any series on behalf of the Holders of all the Securities of such series and any

its consequences, except

     (1) a default 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 the case of any Securities which are convertible into or exchangeable for Common
Stock or other securities or property, a default in any such conversion or exchange, or

     (3) a default 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.

48

 

     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 Usury, 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 or any usury law or any other law wherever enacted, now or at any time
hereafter in force, which would prohibit or forgive the Company from paying all or any portion of
the principal of or premium, if any, or interest, if any on or Additional Amounts, if any, with
respect to any Securities as contemplated herein and therein or which may affect the covenants or
the performance of this Indenture or the Securities; and the Company (to the extent that it may
lawfully do so) expressly waives all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to the Trustee or the
Holders, 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 and disbursements, 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, and, in the case of repayment at the option of the Holder pursuant
to Article Thirteen hereof, on or after the date for repayment) or for the enforcement of the
right, if any, to convert or exchange any Security into Common Stock or other securities in
accordance with its terms.

51

 

     Section 603. Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Securities, except the Trustee’s certificate of
authentication, and in any Coupons shall be taken as the statements of the Company and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture or of the Securities
or the Coupons, except that the Trustee represents that it is duly authorized to execute and
deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that
the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Company are
true and accurate, subject to the qualifications set forth therein. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the Company of the
Securities or the proceeds thereof.

     Section 604. May Hold Securities.

     The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other
Person that may be an agent of the Trustee or the Company, in its individual or any other capacity,
may become the owner or pledgee of Securities or Coupons and, subject to Sections 310(b) and 311 of
the Trust Indenture Act, may otherwise deal with the Company with the same rights it would have if
it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other Person.

     Section 605. Money Held in Trust.

     Except as provided in Section 403 and Section 1003, money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required by law and shall be
held uninvested. The Trustee shall be under no liability for interest on any money received by it
hereunder except as otherwise agreed in writing with the Company.

     Section 606. Compensation and Reimbursement.

     The Company agrees:

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

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

     (3) to indemnify each of the Trustee or any predecessor Trustee and their agents for,
and to hold them harmless against, any loss, liability or reasonable expense (including,
without limitation, the reasonable fees and disbursements of the Trustee’s agents, legal
counsel, accountants and experts, and including taxes other than taxes based

52

 

upon, measured by or determined by the income of the Trustee) incurred without
negligence or bad faith on their part, arising out of or in connection with the acceptance
or administration of the trust or trusts hereunder, including the reasonable costs and
expenses of defending themselves against any claim (whether asserted by the Company, or any
Holder or any other Person) or liability in connection with the exercise or performance of
any of their powers or duties hereunder, or in connection with enforcing the provisions of
this Section, except to the extent that any such loss, liability or expense was due to the
Trustee’s negligence or bad faith.

     As security for the performance of the obligations of the Company under this Section, the
Trustee shall have a lien prior to the Securities of any series upon all property and funds held or
collected by the Trustee as such, except funds held in trust for the payment of principal of, or
premium or interest on or any Additional Amounts with respect to Securities or any Coupons
appertaining thereto.

     Any compensation or expense incurred by the Trustee after a default specified by
Section 501(5) or (6) is intended to constitute an expense of administration under any then
applicable bankruptcy or 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. The provisions of this Section 606 shall, to the
extent permitted by law, survive any termination of this Indenture (including, without limitation,
termination pursuant to any Bankruptcy Laws) and the resignation or removal of the Trustee.

     Section 607. Corporate Trustee Required; Eligibility.

     (1) There shall at all times be a Trustee hereunder that is a corporation, organized and doing
business under the laws of the United States of America, any state thereof or the District of
Columbia, eligible under Section 310(a)(1) of the Trust Indenture Act to act as trustee under an
indenture qualified under the Trust Indenture Act and that 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
subject to supervision or examination by Federal or state authority. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article.

     (2) The following indenture shall be considered specifically described herein for purposes of
clause (i) of the proviso contained in Section 310(b)(1) of the Trust Indenture Act: [Indenture
dated as of                                          between the Company and                   
  , as successor trustee]; and,
pursuant to Section 310(b)(1)(C)(i) of the Trust Indenture Act, unless otherwise ordered by the
Commission, an event of default by the Company under this Indenture will not disqualify the Trustee
under this Indenture because it is a trustee under such other 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.

53

 

     (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
the giving of such notice of resignation, the resigning Trustee may, at the Company’s expense,
petition any court of competent jurisdiction for the appointment of a successor Trustee with
respect to such series.

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

     (4) If at any time:

     (a) the Trustee shall fail to comply with the obligations imposed upon it under Section
310(b) of the Trust Indenture Act with respect to Securities of any series after written
request therefor by the Company or any Holder of a Security of such series who has been a
bona fide Holder of a Security of such series for at least six months, or

     (b) the Trustee shall cease to be eligible under Section 607 and shall fail to resign
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
insolvent or a receiver of the Trustee or of its property shall be appointed or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company, by or pursuant to a Board Resolution, may remove the
Trustee with respect to all Securities or the Securities of such series, or (ii) subject to
Section 315(e) of the Trust Indenture Act, 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 removal of the Trustee
with respect to all Securities of such series and the appointment of a successor Trustee or
Trustees.

     (5) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
series, the Company, by 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

54

 

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 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

55

 

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 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 (provided
that such corporation shall otherwise be qualified and eligible under this Article), without the
execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Securities shall have been authenticated but not delivered by the Trustee then in office,
any such successor 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. In case any Securities shall not have been authenticated by such
predecessor Trustee, any such successor Trustee may authenticate and deliver such Securities in
either its own name or that of its predecessor Trustee.

     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

56

 

Trustee to authenticate Securities of that or those series issued upon original issue,
exchange, registration of transfer, partial redemption, partial repayment, partial conversion or
exchange for Common Stock or other securities or property, 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.

     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.

57

 

     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.

	 	 	 	 	 
	 	 	                                                            ,
	 	 	           As Trustee
	 
	 	 	 	 
	 

	 	By:	 	 
	 

	 	 	 	 
	 

	 	 	 	As Authenticating Agent
	 
	 	 	 	 
	 

	 	By:	 	 
	 

	 	 	 	 
	 

	 	 	 	Authorized Signatory

     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 of 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.

     Section 902. Supplemental Indentures with Consent of Holders.

     With the consent of the Holders of not less than a majority in principal amount of the

under this Section 902 with respect to any one or more series of Outstanding Securities without
entering into a supplemental indenture with respect to any other series of Outstanding Securities.

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

     Section 903. Execution of Supplemental Indentures.

     As a condition to executing, or accepting the additional trusts created by, any supplemental

the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities
of such series.

ARTICLE TEN

COVENANTS

     Section 1001. Payment of Principal, Premium, 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, whether payable in cash, shares
of Common Stock or other securities or property, 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 shall maintain in each Place of Payment for any series of Securities an Office or
Agency where Securities of such series (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, where Securities of such series that are convertible or exchangeable may be
surrendered for conversion 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;
provided that, if (i) the Borough of Manhattan, The City of New York is a Place of Payment for the
Securities of any series, (ii) there shall be another Place of Payment in the United States of
America for such Securities in addition to the Borough of Manhattan, The City of New York, and
(iii) all Securities of such series are originally issued solely in the form of one or more
permanent global Securities, then the Company shall not be required to maintain any

66

 

such office or agency in the Borough of Manhattan, The City of New York unless and until all
or any portion of such global Securities shall be exchanged for or otherwise issued as definitive
certificated Securities of such series as contemplated by the last paragraph of this Section 1002.
If Securities of a series are issuable as Bearer Securities, the Company 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 may be presented and surrendered for payment; provided, however, that if the
Securities of such series are listed on the London Stock Exchange or the Luxembourg Stock Exchange
or any other stock exchange located outside the United States and such stock exchange shall so
require, the Company 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 will give prompt written notice to the Trustee of the
location, and any change in the location, of such Office or Agency. If at any time the Company
shall fail to maintain any such required Office or Agency or shall fail to furnish the Trustee with
the address thereof, such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, except that Bearer Securities of such series and any
Coupons appertaining 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 hereby appoints the Trustee as its 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
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 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 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 the
Borough of Manhattan, the City of New York as a Place of Payment for each series of Securities,
initially appoints the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City
of New York as the Company’s Office or Agency in the Borough of Manhattan, The City of New York for
such purpose and initially appoints the Trustee as the

67

 

Security Registrar for each series of Securities and, if the Securities of any series are
convertible into or exchangeable for Common Stock or other securities or property, initially
appoints the Trustee as conversion or exchange agent, as the case may be, for the Securities of
such series. The Company may subsequently appoint a different Office or Agency in the Borough of
Manhattan, The City of New York and, as provided in Section 305, may remove and replace from time
to time the Security Registrar.

     As set forth above in this Section 1002, and unless otherwise provided pursuant to Section 301
with respect to any series of Securities, in the event that the Securities of a series are
originally issued solely in the form of one or more permanent global Securities and if at any time
thereafter Securities of such series are issued in definitive certificated form in exchange for all
or any portion of such global Securities (whether pursuant to Section 305 or otherwise pursuant to
the terms of such Securities), the Company shall, at all times from and after the date of the first
such exchange until such time as no Securities of such series in definitive certificated form are
Outstanding, establish and maintain an Office or Agency in the Borough of Manhattan, The City of
New York (in addition to any other Offices or Agencies the Company is required to maintain in
respect of such Securities) where Securities of such series may be surrendered and where notices
and demands in respect of Securities of such series and this Indenture may be served for the
purposes specified in, and as contemplated by, the first paragraph of this Section 1002.

     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 any 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 sufficient to pay the principal, any premium,
interest and Additional Amounts, as the case may be, 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, or 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, premium, interest and Additional Amounts, as the case may be, 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

68

 

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.

To the extent that the terms of any Securities established pursuant to Section 301 provide that any
principal of, or premium or interest, if any, on or any Additional Amounts with respect to any such
Securities is or may be payable in Common Stock or other securities or property, then the
provisions of this Section 1003 shall apply, mutatis mutandis, to such Common Stock
or other securities or property.

     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 such
premium or interest or Additional Amount 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, not later than 30 days after the Company’s
request for such repayment, 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 earlier 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.

69

 

     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 Securities 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, 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 any 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 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, if any, 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 or deduction for or on
account of any tax, assessment or other governmental charge described in the Securities of such
series or pursuant to Section 301 with respect to the Securities of such series. If any such
withholding or deduction shall be required, then such Officers’ Certificate shall specify by
country the amount, if any, required to be withheld on or deducted from 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. Nothing in this Section 1004 or elsewhere in this
Indenture shall limit the obligation of the Company to pay Additional Amounts with respect to the
Securities of any series pursuant to the terms, if any, established pursuant to Section 301 with
respect to the Securities of such series.

     Section 1005. Corporate Existence.

     Subject to Article Eight, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect (i) the corporate existence of the Company, (ii) the
existence (corporate or other) of each Significant Subsidiary of the Company and (iii) the rights
(charter and statutory), licenses and franchises of the Company and each of its Significant
Subsidiaries; provided, however, that the Company shall not be required to preserve the existence
(corporate or other) of any of its Significant Subsidiaries or any such right, license or

70

 

franchise of the Company or any of its Significant Subsidiaries if the Board of Directors of
the Company determines that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Significant Subsidiaries taken as a whole and that the loss thereof
will not be disadvantageous in any material respect to the Holders.

     Section 1006. Maintenance of Properties.

     The Company will, and will cause each Significant Subsidiary to, cause all its properties used
or useful in the conduct of its business to be maintained and kept in good condition, repair and
working order and supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that nothing in this Section
shall prevent the Company or any Significant Subsidiary from discontinuing the operation and
maintenance of any of their respective properties if such discontinuance is, in the judgment of the
Board of Directors of the Company or of any Significant Subsidiary, as the case may be, desirable
in the conduct of its business.

     Section 1007. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term, provision or
condition set forth in Sections 1002 to 1006, inclusive, with respect to the Securities of any
series and, if expressly provided pursuant to Section 301(18), any additional covenants applicable
to the Securities of such 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 1008. Company Statement as to Compliance.

     The Company shall deliver to the Trustee, within 180 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 whether or not, to the best of his or her knowledge, the
Company is in default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to notice requirements or periods of grace) and if the
Company shall be in default, specifying all such defaults and the nature and status thereof of
which he or she may have knowledge.

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. In case of any redemption at the election of the Company of less than all of the
Securities of any series, 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 and,
in the event that the Company shall determine that the Securities of any series to be redeemed
shall be selected from Securities of such series having the same issue date, interest rate or
interest rate formula, Stated Maturity and other terms (the “Equivalent Terms”), the Company shall
notify the Trustee of such Equivalent Terms.

     In the case of any redemption of Securities (A) prior to the expiration of any restriction on
such redemption provided in the terms of such Securities or elsewhere in this Indenture or
(B) pursuant to an election of the Company which is subject to a condition specified in the terms
of such Securities or elsewhere in this Indenture, the Company shall furnish to the Trustee an
Officers’ Certificate evidencing compliance with such restriction or condition.

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

     If less than all of the Securities of any series are to be redeemed or if less than all of the
Securities of any series with Equivalent 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 or from the Outstanding Securities of such series with
Equivalent Terms, as the case may be, not previously called for redemption, by lot or 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
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

72

 

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

     Unless otherwise specified in or pursuant to this Indenture or the Securities of any series,
if any Security selected for partial redemption is converted or exchanged for Common Stock or other
securities or property in part before termination of the conversion or exchange right with respect
to the portion of the Security so selected, the converted or exchanged portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption. Securities which
have been converted or exchanged during a selection of Securities to be redeemed shall be treated
by the Trustee as Outstanding for the purpose of such selection.

     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 portions 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) that, in case any Security is to be redeemed in part only, 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, together (if applicable) with
accrued and unpaid interest, if any, thereon (subject, if applicable, to the provisos to the
first paragraph of Section 1106), 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

73

 

Date, are to be surrendered for payment of the Redemption Price and any accrued
interest and Additional Amounts pertaining thereto,

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

     (8) 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,

     (9) 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,

     (10) in the case of Securities of any series that are convertible or exchangeable into
Common Stock or other securities or property, the then current conversion or exchange price
or rate, the date or dates on which the right to convert or exchange the principal of the
Securities of such series to be redeemed will commence or terminate, as applicable, and the
place or places where and the Persons to whom such Securities may be surrendered for
conversion or exchange,

     (11) 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),
and

     (12) if the Redemption Price or any portion thereof shall be payable, at the option of
the Company or any Holders, in cash or in Common Stock or other securities or property (or a
combination thereof), a statement as to whether the Company has elected to pay the
Redemption Price in cash or Common Stock or other securities or property or a combination
thereof and, if applicable, the portion of the Redemption Price that is to be paid in cash,
Common Stock or other securities or property.

     A notice of redemption published 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 delivered at least 10 days before the date such
notice is to be given (unless a shorter period shall be acceptable to the Trustee), by the Trustee
in the name and at the expense of the Company.

     Section 1105. Deposit of Redemption Price.

     On or prior to noon (local time in New York City) on 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

74

 

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 for or in the Securities of such series) any accrued interest on and Additional Amounts with
respect to, all such Securities or portions thereof which are to be redeemed on that date, except
that, if the Securities of such series are convertible or exchangeable into Common Stock or other
securities or property, no such deposit shall be required with respect to any such Securities (or
portions thereof) which have been converted or exchanged prior to such Redemption Date.

     Section 1106. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed (except,
in the case of Securities which are convertible or exchangeable into Common Stock or other
securities or property, any such Securities which shall have been so converted or exchanged prior
to the applicable Redemption Date) shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, together with (unless otherwise provided with respect to the
Securities of such series pursuant to Section 301) accrued and unpaid interest, if any, thereon and
from and after such date (unless the Company shall default in the payment of the Redemption Price
and accrued interest, if any) 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, unless otherwise
provided in or pursuant to this Indenture, any accrued and unpaid interest thereon and Additional
Amounts with respect thereto to but excluding 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 or, at the option of the Company, after payment to the Trustee for the benefit of
the Company of, 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

75

 

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 or, if no rate is prescribed therefor in the
Security, at the rate of interest, if any, borne by such 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 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

SINKING FUNDS

     Section 1201. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of
Securities of a series that by its terms provides for such a sinking fund, except as otherwise
permitted or required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

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

76

 

     Section 1202. Satisfaction of Sinking Fund Payments with Securities.

     The Company may, in satisfaction of all or any part of any sinking fund payment with respect
to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver
Outstanding Securities of such series (other than any of such Securities previously called for
redemption or any of such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all unmatured Coupons
appertaining thereto, and (2) apply as a credit Securities of such series which have been redeemed
either at the election of the Company pursuant to the terms of such series of Securities or through
the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such Securities have not been previously so credited. Such Securities
shall be received and credited for such purpose by the Trustee at the Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities
of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of
Securities of such series to be redeemed in order to exhaust the aforesaid cash payment shall be
less than $100,000, the Trustee need not call Securities of such series for redemption, except upon
Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied
to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying
Agent shall at the request of the Company from time to time pay over and deliver to the Company any
cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the
Trustee of Securities of that series purchased by the Company having an unpaid principal amount
equal to the cash payment requested to be released to the Company.

     Section 1203. Redemption of Securities for Sinking Fund.

     Not less than 75 days prior to each sinking fund payment date for any series of Securities,
the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next
ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the
portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory
sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added
in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be
obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund
payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment
date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in Section 1104. Such
notice having been duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 1106 and 1107.

77

 

ARTICLE THIRTEEN

REPAYMENT AT THE OPTION OF HOLDERS

     Section 1301. 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 1301, 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 applicable 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.

     Unless otherwise expressly stated in this Indenture or pursuant to Section 301 with respect to
the Securities of any series or unless the context otherwise requires, all references in this
Indenture to the repayment of Securities at the option of the Holders thereof (and all references
of like import) shall be deemed to include a reference to the repurchase of Securities at the
option of the Holders thereof.

ARTICLE FOURTEEN

SECURITIES IN FOREIGN CURRENCIES

     Section 1401. 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 of any series in which not
all of such Securities are denominated in the same Currency, in the absence of any provision to the
contrary in or pursuant to this Indenture or the Securities of such series, any amount in respect
of any Security denominated in a Currency other than Dollars shall be treated for any such action,
determination 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 or distribution (or, if there shall be no
applicable record date, such other date reasonably proximate to the date of such distribution) as
the Company may specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

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, 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

the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified
in Section 1501, by written request setting forth in reasonable detail the action proposed to be

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

     The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a
series shall constitute a quorum for a meeting or duly reconvened 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

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 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
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 at least 66-2/3% in principal amount of the Outstanding

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.

80

 

     Section 1505. 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 1502(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. If
the Securities of such series are issuable in minimum denominations of less than $1,000, then a
Holder of such a Security in a principal amount of less than $1,000 shall be entitled to a fraction
of one vote which is equal to the fraction that the principal amount of such Security bears to
$1,000. 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 1502 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 1506. 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

81

 

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 1502 and,
if applicable, Section 1504. 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.

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

12

in any such global Security through such Depository’s standing instructions and customary
practices.

     (2) The fact and date of the execution by any Person of any such instrument or writing may be

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 Securities, if such
certificate or affidavit is deemed by the Company and 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.

     (5) 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,

13

 

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.

     (6) 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.

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

14

 

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 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

provision of the Trust Indenture Act imposed hereon by Section 318(c) thereof, such required
provision shall control.

     Section 111. Separability Clause.

     In case any provision in this Indenture, any Security or any Coupon shall be invalid, illegal
or unenforceable, the validity, legality and enforceability of the remaining provisions shall not,
to the fullest extent permitted by law, 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
successors hereunder and the Holders of Securities or Coupons, and the holders of Senior
Indebtedness with respect to such series, any benefit or any legal or 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.

     Section 114. Legal Holidays.

     Unless otherwise specified in or pursuant to this Indenture or any Securities, in any case
where any Interest Payment Date, Stated Maturity or Maturity of, or any other day on which a
payment is due with respect to, any Security shall be a day which is not a Business Day 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 or in the Board Resolution, Officers’
Certificate or supplemental indenture establishing the terms of any Security that specifically
states that such provision shall apply in lieu hereof) payment need not be made at such Place of
Payment on such date, but such payment may be made on the next succeeding day that is a Business
Day at such Place of Payment with the same force and effect as if made on the Interest Payment
Date, at the Stated Maturity or Maturity or on any such other payment date, as the case may be, 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, Stated Maturity, Maturity or other payment date, 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.

     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

16

 

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) its obligations under this Indenture to make
payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with 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
order to be closed. The provisions of this Section 116 shall not be applicable with respect to any
payment due on a Security which is payable in Dollars.

     Section 117. Extension of Payment Dates.

     In the event that (i) the terms of any Security or Coupon appertaining thereto established in
or pursuant to this Indenture permit the Company or any Holder thereof to extend the date on which
any payment of principal of, or premium, if any, or interest, if any, on, or Additional Amounts, if
any, with respect to such Security or Coupon is due and payable and (ii) the due date for any such
payment shall have been so extended, then all references herein to the Stated Maturity of such
payment (and all references of like import) shall be deemed to refer to the date as so extended.

     Section 118. Immunity of Stockholders, Directors, Officers and Agents of the Company.

     No recourse under or upon any obligation, covenant or agreement contained in this Indenture,
or in any Security, or because of any indebtedness evidenced thereby, shall be had against any
past, present or future stockholder, employee, officer or director, as such, of the Company or of
any predecessor or successor, either directly or through the Company or any predecessor or
successor, under any rule of law, statute or constitutional provision or by the enforcement of any
assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly
waived and released by the acceptance of the Securities by the Holders and as part of the
consideration for the issue of the Securities.

     Section 119. Waiver of Jury Trial.

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

17

 

          Section 120. Force Majeure.

forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts
of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of
God, and interruptions, loss or malfunctions of utilities, communications or computer (software and

     Authorized Signatory

          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 global form. If Securities of a series shall be issuable in temporary or
permanent 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 or reflected on the books
and records of the Trustee 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 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
pursuant to Section 301 with respect to such Security 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 global form in
the manner and upon instructions given by the Person or Persons specified therein or pursuant to
Section 301 with respect to such Security 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 foregoing provisions of this paragraph, in the event a global Security is
exchangeable for definitive Securities as provided in Section 305, then, unless otherwise provided
in or pursuant to this Indenture with respect to the Securities of such series, the Trustee shall
deliver and redeliver such global Security to the extent necessary to effect such exchanges, shall
endorse such global Security to reflect any decrease in the principal amount thereto resulting from
such exchanges and shall take such other actions, all as contemplated by Section 305.

     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

19

 

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.

     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

24

 

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, its President or one of
its Vice Presidents and by its Treasurer, its Secretary or one of its Assistant Secretaries and may
(but need not) have its corporate seal or a facsimile thereof reproduced thereon. Coupons shall be
executed on behalf of the Company by the Chairman, the President or any Vice President 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, to the fullest extent
permitted by law, 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, an Opinion of Counsel to the following effect, which Opinion of
Counsel may contain such assumptions, qualifications and limitations as such counsel shall deem
appropriate:

     (a) the form or forms and terms of such Securities and Coupons, if any, have been
established in conformity with Sections 201 and 301 of this Indenture;

     (b) all conditions precedent set forth in Sections 201, 301 and 303 of this Indenture
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 (if applicable), executed 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 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

25

 

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).

     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 at the time of issuance of each Security, but such
opinion, with such modifications as counsel shall deem appropriate, 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 signatories. 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 or as may otherwise be provided in or pursuant to this Indenture,
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.

     Except in the case of temporary Securities in global form, which shall be exchanged in
accordance with the provisions set forth in this Indenture or the provisions established pursuant

26

 

to Section 301, if temporary Securities are issued, the Company shall cause definitive
Securities to be prepared without unreasonable delay. Except as otherwise provided in or pursuant
to this Indenture, 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.
Except as otherwise provided in or pursuant to this Indenture, 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 initial Security Registrar for each series of
Securities shall be as specified in the penultimate paragraph of Section 1002. 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. 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.

     Except as otherwise provided in or pursuant to this Indenture, 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.

     Except as otherwise provided in or pursuant to this Indenture, at the option of the Holder,
Registered Securities of any series may be exchanged for other Registered Securities of the same

27

 

series containing identical terms and provisions, in any authorized denominations, and of a
like aggregate principal amount, upon surrender of the 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.

28

 

     Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture,
the global Securities of any series shall be exchangeable for definitive certificated Securities of
such series only if (i) the Depository for such global Securities notifies the Company that it is
unwilling or unable to continue as a Depository for such global Securities or at any time the
Depository for such global Securities ceases to be a clearing agency registered as such under the
Exchange Act, if so required by applicable law or regulation, and no successor Depository for such
Securities shall have been appointed within 90 days of such notification or of the Company becoming
aware of the Depository’s ceasing to be so registered, as the case may be, (ii) the Company, in its
sole discretion, determines that the Securities of such series shall no longer be represented by
one or more global Securities and executes and delivers to the Trustee a Company Order to the
effect that such global Securities shall be so exchangeable, or (iii) an Event of Default has
occurred and is continuing with respect to such 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 paragraph, 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 Depository (or its custodian) as shall be specified in the
Company Order with respect thereto (which the Company agrees to deliver), and in accordance with
instructions given to the Trustee and the Depository (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, and which shall be in such denominations and,
in the case of Registered Securities, registered in such names, as shall be specified by the
Depository, 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 its custodian) or such other Depository (or its custodian)
referred to above in accordance with the instructions of the Company referred to above, and the
Trustee shall endorse such global Security to reflect the decrease in the principal amount thereof
resulting from such exchange. If a Registered

29

 

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, 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 of Securities, or
any redemption or repayment of Securities, or any conversion or exchange of Securities for other
types of securities or property, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section 304, 905 or 1107, upon
repayment or repurchase in part of any Registered Security pursuant to Article Thirteen, or upon
surrender in part of any Registered Security for conversion or exchange into Common Stock or other
securities or property pursuant to its terms, in each case not involving any transfer.

     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 terms and of 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, or portion thereof, so selected for redemption, except in the case of any
Registered 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 terms and of the same series, provided that such Registered Security shall be
simultaneously 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
pursuant to Article Thirteen and not withdrawn, except the portion, if any, of such Security not to
be so repaid.

30

 

     The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance
with any restrictions on transfer imposed under this Indenture or under applicable law with respect
to any transfer of any interest in any Security (including any transfers between or among
Depositary participants or beneficial owners of interests in any Global Security) other than to
require delivery of such certificates and other documentation or evidence as are expressly required
by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the
same to determine substantial compliance as to form with the express requirements hereof.

     Neither the Trustee nor any Paying Agent shall have any responsibility for any actions taken
or not taken by the Depositary.

          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 acquired by a
bona fide purchaser, the Company shall execute and, upon the Company’s 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 payment of 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

31

 

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 any 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 (to the extent lawful) 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 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

32

 

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 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 of America.

     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

33

 

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, 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, 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.

     Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, any
Paying Agent or the Security Registrar from giving effect to any written certification, proxy or
other authorization furnished by the applicable Depository, as a Holder, with respect to a global
Security or impair, as between such Depository and the owners of beneficial interests in such
global Security, the operation of customary practices governing the exercise of the rights of such
Depository (or its nominee) as the Holder of such global Security.

          Section 309. Cancellation.

     All Securities and Coupons surrendered for payment, redemption, registration of transfer,
exchange or conversion or for credit against any sinking fund payment 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

34

 

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 disposed of in accordance with its procedures for the disposition of cancelled
securities and the Trustee shall deliver to the Company a certificate of such disposition, 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 the Securities of any
series, 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.

     Unless, pursuant to Section 301, the provisions of this Section 401 shall not be applicable
with respect to the Securities of any series, 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 1106, and (iv) Securities and Coupons of such series
for whose payment money 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, if
applicable, any Coupons appertaining thereto not theretofore delivered to the
Trustee for cancellation

     (i) have become due and payable, or

35

 

     (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, to the extent that the Securities of
such series provide for the payment of Additional Amounts thereon and the amount of
any such Additional Amounts which are or will be payable with respect to the
Securities of such series is at the time of deposit determinable by the Company (in
the exercise by the Company of its reasonable discretion), 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 Outstanding 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, 404, 1002, 1003 and, if applicable to the Securities of such series, 1004
(including, without limitation, 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)), any rights of Holders of the Securities
of such series (unless otherwise provided pursuant to Section 301 with respect to the Securities of
such series) to require the Company to repurchase or repay, and the obligations of

36

 

the Company to repurchase or repay, such Securities at the option of the Holders pursuant to
Article Thirteen hereof, and any rights of Holders of the Securities of such series (unless
otherwise provided pursuant to Section 301 with respect to the Securities of such series) to
convert or exchange, and the obligations of the Company to convert or exchange, such Securities
into Common Stock or other securities or property, 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, at any time, with respect to the
Securities of or within such series 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. Unless otherwise
specified pursuant to Section 301 with respect to the Securities of any series, defeasance under
clause (2) of this Section 402 and covenant defeasance under clause (3) of this Section 402 may be
effected only with respect to all, and not less than all, of the Outstanding Securities of any
series. To the extent that the terms of any Security or Coupon appertaining thereto established in
or pursuant to this Indenture permit the Company or any Holder thereof to extend the date on which
any payment of principal of, or premium, if any, or interest, if any, on, or Additional Amounts, if
any, with respect to such Security or Coupon is due and payable, then unless otherwise provided
pursuant to Section 301, the right to extend such date shall terminate upon defeasance or covenant
defeasance, as the case may be.

     (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) through (iv) of this paragraph, 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 (except as provided in clause (ii) below) from the trust fund described in clause
(4)(a) of this Section 402 and as more fully set forth in this Section 402 and 403, 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, (ii) the obligations of the Company and the Trustee with respect to such Securities under
Sections 305, 306, 1002, 1003 and, if applicable to the Securities of such series, 1004 (including,
without limitation, with respect to the payment of Additional Amounts, if any, with respect

37

 

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 clause (4)(a) of this Section 402)), any rights of Holders of such
Securities (unless otherwise provided pursuant to Section 301 with respect to the Securities of
such series) to require the Company to repurchase or repay, and the obligations of the Company to
repurchase or repay, such Securities at the option of the Holders pursuant to Article Thirteen
hereof, and any rights of Holders of such Securities (unless otherwise provided pursuant to Section
301 with respect to the Securities of such series) to convert or exchange, and the obligations of
the Company to convert or exchange, such Securities into Common Stock or other securities or
property, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv)
this Section 402 and Sections 403 and 404. The Company may exercise its option under this Section
402(2) notwithstanding the prior exercise of its option under Section 402(3) 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 clauses (ii) and (iii) of Section 1005 and under Sections 1006, 1007, and 1008 and any other
covenant applicable to such Securities with respect to such Securities and any Coupons appertaining
thereto shall cease to be applicable to such Securities 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 any 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(4) or 501(8) 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, if such defeasance or covenant defeasance is to be effected in compliance with
subsection (f) below, on the relevant Redemption Date, as the case may be, 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 or, if

38

 

such defeasance or covenant defeasance is to be effected in compliance with subsection
(f) below, on the relevant Redemption Date, as the case may be) 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, (y) the
principal of (and premium, if any) and interest, if any, on, and, to the extent that such
Securities provide for the payment of Additional Amounts thereon and the amount of any such
Additional Amounts which are or will be payable with respect to the Securities of such
series is at the time of deposit determinable by the Company (in the exercise by the Company
of its reasonable discretion), any Additional Amounts with respect to, such Outstanding
Securities and any Coupons appertaining thereto on the Stated Maturity of such principal or
installment of principal or interest or the applicable Redemption Date, as the case may be,
and (z) any mandatory sinking fund payments or analogous payments applicable to such
Outstanding Securities and any Coupons appertaining thereto 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 Subsidiary 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, solely in
the case of defeasance under Section 402(2), no Event of Default with respect to such
Securities and any Coupons appertaining thereto under clause (5) or (6) of Section 501 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 under clause (5) or (6) of
Section 501 shall have occurred and be continuing at any time during the period ending on
and including the 91st day after the date of such deposit (it being understood that this
condition to defeasance under Section 402(2) shall not be deemed satisfied until the
expiration of such period).

     (d) In the case of defeasance pursuant to Section 402(2), the Company shall have
delivered to the Trustee an opinion of independent counsel reasonably acceptable to the
Trustee stating that (x) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling, or (y) since the date of this Indenture there has been a
change in applicable federal income tax law, in either case to the effect that, and based
thereon such opinion of independent counsel 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

39

 

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; or, in the
case of covenant defeasance pursuant to Section 402(3), the Company shall have delivered to
the Trustee an opinion of independent counsel reasonably acceptable to the Trustee 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.

     (e) 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, as the case may be, under this Indenture have been complied with.

     (f) If the monies or Government Obligations or combination thereof, as the case may be,
deposited under clause (a) above are sufficient to pay the principal of, and premium, if
any, and interest, if any, on and, to the extent provided in such clause (a), Additional
Amounts with respect to, such Securities provided such Securities are redeemed on a
particular Redemption Date, the Company shall have given the Trustee irrevocable
instructions to redeem such Securities on such date and to provide notice of such redemption
to Holders as provided in or pursuant to this Indenture.

     (g) No event or condition will exist pursuant to the terms of Section 301(26) that
would prevent the Company from making payments of principal and premium, if any, and
interest on the Securities at the date of the irrevocable deposit referred to above.

     (h) 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)(a) 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 (other than the Company or any Subsidiary or Affiliate of the Company acting as 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 Securities, 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

40

 

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)(a) 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 other qualifying trustee appointed pursuant to Section 402(4)(a)) or any
Paying Agent is unable to apply any moneys or Government Obligations deposited pursuant to Section
401(1) or 402(4)(a) to pay any principal of or premium, if any, or interest, if any, on or
Additional Amounts, if any, with respect to the Securities of any series by reason of any legal

41

 

proceeding or any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the Company’s obligations under this
Indenture and the Securities of such series shall be revived and reinstated as though no such
deposit had occurred, until such time as the Trustee (or other qualifying trustee) or Paying Agent
is permitted to apply all such moneys and Government Obligations to pay the principal of and
premium, if any, and interest, if any, on and Additional Amounts, if any, in respect of the
Securities of such series as contemplated by Sections 401 or 402 as the case may be, and Section
403; provided, however, that if the Company makes any payment of the principal of or premium, if
any, or interest if any, on or Additional Amounts, if any, in respect of the Securities of such
series following the reinstatement of its obligations as aforesaid, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the funds held by the
Trustee (or other qualifying trustee) or Paying Agent.

          Section 405. Effect on Subordination Provisions.

     Unless otherwise expressly provided pursuant to Section 301 with respect to the Securities of
any series, the provisions of Article Sixteen hereof, insofar as they pertain to the Securities of
such series, and the Subordination Provisions established pursuant to Section 301(26) with respect
to such series are hereby expressly made subject to the provisions for satisfaction and discharge
set forth in Section 401 hereof and the provisions for defeasance and covenant defeasance set forth
in Section 402 hereof and, anything herein to the contrary notwithstanding, upon the effectiveness
of such satisfaction and discharge pursuant to Section 401 with respect to the Securities of such
series or any such defeasance or covenant defeasance pursuant to Section 402 with respect to the
Securities of or within such series, all of the Securities of such series (in the case of
satisfaction and discharge pursuant to Section 401) or the Securities of such series as to which
defeasance or covenant defeasance, as the case may be, shall have become effective shall thereupon
cease to be so subordinated and shall no longer be subject to the provisions of Article Sixteen or
the Subordination Provisions established pursuant to Section 301(26) with respect to such
Securities and, without limitation to the foregoing, all moneys, Government Obligations and other
securities or property deposited with the Trustee (or other qualifying trustee) in trust in
connection with such satisfaction and discharge, defeasance or covenant defeasance, as the case may
be, and all proceeds therefrom may be applied to pay the principal of, premium, if any, and
interest, if any, on, and Additional Amounts, if any, with respect to such Securities as and when
the same shall become due and payable notwithstanding the provisions of Article Sixteen or such
Subordination Provisions.

     (8) any other Event of Default provided in or pursuant to this Indenture with respect

          Section 502. Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in clause (5) or (6) of
Section 501) with respect to Securities of any series occurs and is continuing, then either the
Trustee or the Holders of not less than 25% in aggregate 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, and accrued and unpaid
interest, if any, thereon 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, as the case may be, and such accrued and unpaid interest shall become immediately
due and payable. If an Event of Default specified in clause (5) or (6) of Section 501 with respect
to the Securities of any series occurs, then the principal of all of the Securities of such series,
or such lesser amount as may be provided for in the Securities of such

44

 

series, and accrued and unpaid interest, if any, thereon 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 the Securities of such 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 aggregate 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
(or, to the extent that the terms of the Securities of such series established pursuant to
Section 301 expressly provide for payment to be made in shares of Common Stock or other
securities or property, shares of Common Stock or other securities or property, together
with cash in lieu of fractional shares or securities, sufficient to pay)

     (a) all overdue installments of any interest on any Securities of such series
and any Coupons appertaining thereto which have become due otherwise than by such
declaration of acceleration and any Additional Amounts with respect 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 any
Additional Amounts with respect thereto and, to the extent permitted by applicable
law, interest thereon at the rate or respective rates, as the case may be, provided
for in or with respect to such Securities, or, if no such rate or rates are so
provided, at the rate or respective rates, as the case may be, of interest borne by
such Securities,

     (c) to the extent permitted by applicable law, interest upon installments of
any interest, if any, which have become due otherwise than by such declaration of
acceleration and any Additional Amounts with respect thereto at the rate or
respective rates, as the case may be, provided for in or with respect to such
Securities, or, if no such rate or rates are so provided, at the rate or respective
rates, as the case may be, of interest borne by 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.

45

 

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

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

     The Company covenants that if:

     (1) default is made in the payment of any interest on, or any Additional Amounts
payable in respect of any interest on, any Security or any Coupon appertaining thereto when
such interest or Additional Amounts, as the case may be, shall have become due and payable
and such default continues for a period of 30 days, or

     (2) default is made in the payment of any principal of or premium, if any, on, or any
Additional Amounts payable in respect of any principal of or premium, if any, on, any
Security at its Maturity, or

     (3) default is made in the deposit of any sinking fund payment when due,

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 permitted by applicable law, upon any overdue
installments of interest and Additional Amounts at the rate or respective rates, as the case may
be, provided for or with respect to such Securities or, if no such rate or rates are so provided,
at the rate or respective rates, as the case may be, of interest borne by 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.

     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.

47

 

     Section 506. Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article with respect to the Securities of
any series shall be applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any premium, interest or
Additional Amounts, upon presentation of such Securities or the Coupons, if any, appertaining
thereto, or both, as the case may be, and the notation thereon of the payment if only partially

Coupons for principal and any premium, interest and Additional Amounts in respect of which

and Coupons for principal and any premium, interest and Additional Amounts;

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

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

48

 

     (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, if any, and (subject to Sections 305 and 307) interest, if any, on and any Additional
Amounts with respect to such Security or 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 pursuant to Article Thirteen hereof
at the option of such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and, in the case of any Security which is convertible into or exchangeable for
other securities or property, to convert or exchange, as the case may be, such Security in
accordance with its terms, and to institute suit for the enforcement of any such payment and any
such right to convert or exchange, 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.

     To the extent permitted by applicable law and 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

49

 

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, to the extent permitted by applicable
law, 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, to the extent permitted by applicable law, 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.

     The Holders of a majority in aggregate 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 aggregate 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 default hereunder with respect to such series and
its consequences, except

     (1) a default 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 the case of any Securities which are convertible into or exchangeable for Common
Stock or other securities or property, a default in any such conversion or exchange, or

     (3) a default 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.

50

 

     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 Usury, 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 or any usury law or any other law wherever enacted, now or at any time
hereafter in force, which would prohibit or forgive the Company from paying all or any portion of
the principal of or premium, if any, or interest, if any on or Additional Amounts, if any, with
respect to any Securities as contemplated herein and therein or which may affect the covenants or
the performance of this Indenture or the Securities; and the Company (to the extent that it may
lawfully do so) expressly waives all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to the Trustee or the
Holders, 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 and disbursements, 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, and, in the case of repayment at the option of the Holder pursuant
to Article Thirteen hereof, on or after the date for repayment) or for the enforcement of the
right, if any, to convert or exchange any Security into Common Stock or other securities in
accordance with its terms.

     The recitals contained herein and in the Securities, except the Trustee’s certificate of
authentication, and in any Coupons shall be taken as the statements of the Company and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee

deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that
the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Company are
true and accurate, subject to the qualifications set forth therein. Neither the Trustee nor any

hereunder except as otherwise agreed in writing with the Company.

     Section 606. Compensation and Reimbursement.

     The Company agrees:

     (1) to pay to the Trustee from time to time reasonable compensation for all services

of law in regard to the compensation of a trustee of an express trust);

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

     (3) to indemnify each of the Trustee or any predecessor Trustee and their agents for,
and to hold them harmless against, any loss, liability or reasonable expense (including,
without limitation, the reasonable fees and disbursements of the Trustee’s agents, legal

expenses of defending themselves against any claim (whether asserted by the Company, or any
Holder or any other Person) or liability in connection with the exercise or performance of
any of their powers or duties hereunder, or in connection with enforcing the provisions of
this Section, except to the extent that any such loss, liability or expense was due to the
Trustee’s negligence or bad faith.

     As security for the performance of the obligations of the Company under this Section, the

collected by the Trustee as such, except funds held in trust for the payment of principal of, or
premium or interest on or any Additional Amounts with respect to Securities or any Coupons
appertaining thereto.

     Any compensation or expense incurred by the Trustee after a default specified by
Section 501(5) or (6) is intended to constitute an expense of administration under any then
applicable bankruptcy or 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. The provisions of this Section 606 shall, to the
extent permitted by law, survive any termination of this Indenture (including, without limitation,
termination pursuant to any Bankruptcy Laws) and the resignation or removal of the Trustee.

     Section 607. Corporate Trustee Required; Eligibility.

     (1) There shall at all times be a Trustee hereunder that is a corporation, organized and doing
business under the laws of the United States of America, any state thereof or the District of
Columbia, eligible under Section 310(a)(1) of the Trust Indenture Act to act as trustee under an
indenture qualified under the Trust Indenture Act and that 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
subject to supervision or examination by Federal or state authority. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this Article.

     (2) The following indenture shall be considered specifically described herein for purposes of
clause (i) of the proviso contained in Section 310(b)(1) of the Trust Indenture Act: Indenture
dated as of                      between the Company and                     , as successor trustee; and,
pursuant to Section 310(b)(1)(C)(i) of the Trust Indenture Act, unless otherwise ordered by the
Commission, an event of default by the Company under this Indenture will not disqualify the Trustee
under this Indenture because it is a trustee under such other 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.

55

 

     (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
the giving of such notice of resignation, the resigning Trustee may, at the Company’s expense,
petition any court of competent jurisdiction for the appointment of a successor Trustee with
respect to such series.

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

     (4) If at any time:

     (a) the Trustee shall fail to comply with the obligations imposed upon it under Section
310(b) of the Trust Indenture Act with respect to Securities of any series after written
request therefor by the Company or any Holder of a Security of such series who has been a
bona fide Holder of a Security of such series for at least six months, or

     (b) the Trustee shall cease to be eligible under Section 607 and shall fail to resign
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
insolvent or a receiver of the Trustee or of its property shall be appointed or any public
officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company, by or pursuant to a Board Resolution, may remove the
Trustee with respect to all Securities or the Securities of such series, or (ii) subject to
Section 315(e) of the Trust Indenture Act, 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 removal of the Trustee
with respect to all Securities of such series and the appointment of a successor Trustee or
Trustees.

     (5) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more
series, the Company, by 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

56

 

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 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

57

 

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 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 (provided
that such corporation shall otherwise be qualified and eligible under this Article), without the
execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Securities shall have been authenticated but not delivered by the Trustee then in office,
any such successor 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. In case any Securities shall not have been authenticated by such
predecessor Trustee, any such successor Trustee may authenticate and deliver such Securities in
either its own name or that of its predecessor Trustee.

     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, partial repayment, partial conversion or exchange for
Common Stock or other securities or property, 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.

58

 

     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.

     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:

59

 

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

	 	 	 	 	 	 	 
	 

	 	 	 	 	 	 
	 	 	 	 	 
	 

	 	 	, 	 	 	 
	 	 	 	 	 	 	 
	 

	 	 	 	As Trustee	 	 
	 
	 	 	 	 	 	 
	 

	 	By:	 	 	 	 
	 

	 	 	 	 	 	 
	 

	 	 	 	As Authenticating Agent	 	 
	 
	 	 	 	 	 	 
	 

	 	By:	 	 	 	 
	 

	 	 	 	 	 	 
	 

	 	 	 	Authorized Signatory	 	 

     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 of 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.

     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, whether payable in cash, shares
of Common Stock or other securities or property, 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 shall maintain in each Place of Payment for any series of Securities an Office or
Agency where Securities of such series (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, where Securities of such series that are convertible or exchangeable may be
surrendered for conversion 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,
provided that, if (i) the Borough of Manhattan, the City of New York is a Place of Payment for the
Securities of any series, (ii) there shall be another Place of Payment in the United States of
America for such Securities in addition to the Borough of Manhattan, the City of New York, and
(iii) all Securities of such series are originally issued solely in the form of one or more
permanent global Securities, then the Company shall not be required to maintain any

68

 

such office or agency in the Borough of Manhattan, the City of New York unless and until all
or any portion of such global Securities shall be exchanged for or otherwise issued as definitive
certificated Securities of such series as contemplated by the last paragraph of this Section 1002.
If Securities of a series are issuable as Bearer Securities, the Company 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 may be presented and surrendered for payment; provided, however, that if the
Securities of such series are listed on the London Stock Exchange or the Luxembourg Stock Exchange
or any other stock exchange located outside the United States and such stock exchange shall so
require, the Company 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 will give prompt written notice to the Trustee of the
location, and any change in the location, of such Office or Agency. If at any time the Company
shall fail to maintain any such required Office or Agency or shall fail to furnish the Trustee with
the address thereof, such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, except that Bearer Securities of such series and any
Coupons appertaining 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 hereby appoints the Trustee as its 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
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 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 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 the
Borough of Manhattan, the City of New York as a Place of Payment for each series of Securities,
initially appoints the Corporate Trust Office of the Trustee in the Borough of Manhattan, the City
of New York as the Company’s Office or Agency in the Borough of Manhattan, The City of New York for
such purpose and initially appoints the Trustee as the

69

 

Security Registrar for each series of Securities and, if the Securities of any series are
convertible into or exchangeable for Common Stock or other securities or property, initially
appoints the Trustee as conversion or exchange agent, as the case may be, for the Securities of
such series. The Company may subsequently appoint a different Office or Agency in the Borough of
Manhattan, The City of New York and, as provided in Section 305, may remove and replace from time
to time the Security Registrar.

     As set forth above in this Section 1002, and unless otherwise provided pursuant to Section 301
with respect to any series of Securities, in the event that the Securities of a series are
originally issued solely in the form of one or more permanent global Securities and if at any time
thereafter Securities of such series are issued in definitive certificated form in exchange for all
or any portion of such global Securities (whether pursuant to Section 305 or otherwise pursuant to
the terms of such Securities), the Company shall, at all times from and after the date of the first
such exchange until such time as no Securities of such series in definitive certificated form are
Outstanding, establish and maintain an Office or Agency in the Borough of Manhattan, the City of
New York (in addition to any other Offices or Agencies the Company is required to maintain in
respect of such Securities) where Securities of such series may be surrendered and where notices
and demands in respect of Securities of such series and this Indenture may be served for the
purposes specified in, and as contemplated by, the first paragraph of this Section 1002.

     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 any 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 sufficient to pay the principal, any premium,
interest and Additional Amounts, as the case may be, 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, or 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, premium, interest and Additional Amounts, as the case may be, 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

70

 

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.

To the extent that the terms of any Securities established pursuant to Section 301 provide that any
principal of, or premium or interest, if any, on or any Additional Amounts with respect to any such
Securities is or may be payable in Common Stock or other securities or property, then the
provisions of this Section 1003 shall apply, mutatis mutandis, to such Common Stock
or other securities or property.

     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 such
premium or interest or Additional Amount 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, not later than 30 days after the Company’s
request for such repayment, 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 earlier 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.

71

 

     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 Securities 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, 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 any 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 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, if any, 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 or deduction for or on
account of any tax, assessment or other governmental charge described in the Securities of such
series or pursuant to Section 301 with respect to the Securities of such series. If any such
withholding or deduction shall be required, then such Officers’ Certificate shall specify by
country the amount, if any, required to be withheld on or deducted from 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. Nothing in this Section 1004 or elsewhere in this
Indenture shall limit the obligation of the Company to pay Additional Amounts with respect to the
Securities of any series pursuant to the terms, if any, established pursuant to Section 301 with
respect to the Securities of such series.

     Section 1005. Corporate Existence.

     Subject to Article Eight, the Company shall do or cause to be done all things necessary to
preserve and keep in full force and effect (i) the corporate existence of the Company, (ii) the
existence (corporate or other) of each Significant Subsidiary of the Company and (iii) the rights
(charter and statutory), licenses and franchises of the Company and each of its Significant
Subsidiaries; provided, however, that the Company shall not be required to preserve the existence
(corporate or other) of any of its Significant Subsidiaries or any such right, license or

72

 

franchise of the Company or any of its Significant Subsidiaries if the Board of Directors of
the Company determines that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Significant Subsidiaries taken as a whole and that the loss thereof
will not be disadvantageous in any material respect to the Holders.

     Section 1006. Maintenance of Properties.

     The Company will, and will cause each Significant Subsidiary to, cause all its properties used
or useful in the conduct of its business to be maintained and kept in good condition, repair and
working order and supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that nothing in this Section
shall prevent the Company or any Significant Subsidiary from discontinuing the operation and
maintenance of any of their respective properties if such discontinuance is, in the judgment of the
Board of Directors of the Company or of any Significant Subsidiary, as the case may be, desirable
in the conduct of its business.

     Section 1007. Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any term, provision or
condition set forth in Sections 1002 to 1006, inclusive, with respect to the Securities of any
series and, if expressly provided pursuant to Section 301(18), any additional covenants applicable
to the Securities of such 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 1008. Company Statement as to Compliance.

     The Company shall deliver to the Trustee, within 180 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 whether or not, to the best of his or her knowledge, the
Company is in default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to notice requirements or periods of grace) and if the
Company shall be in default, specifying all such defaults and the nature and status thereof of
which he or she may have knowledge.

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. In case of any redemption at the election of the Company of less than all of the
Securities of any series, 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 and,
in the event that the Company shall determine that the Securities of any series to be redeemed
shall be selected from Securities of such series having the same issue date, interest rate or
interest rate formula, Stated Maturity and other terms (the “Equivalent Terms”), the Company shall
notify the Trustee of such Equivalent Terms.

     In the case of any redemption of Securities (A) prior to the expiration of any restriction on
such redemption provided in the terms of such Securities or elsewhere in this Indenture or
(B) pursuant to an election of the Company which is subject to a condition specified in the terms
of such Securities or elsewhere in this Indenture, the Company shall furnish to the Trustee an
Officers’ Certificate evidencing compliance with such restriction or condition.

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

     If less than all of the Securities of any series are to be redeemed or if less than all of the
Securities of any series with Equivalent 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 or from the Outstanding Securities of such series with
Equivalent Terms, as the case may be, not previously called for redemption, by lot or 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
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

74

 

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

     Unless otherwise specified in or pursuant to this Indenture or the Securities of any series,
if any Security selected for partial redemption is converted or exchanged for Common Stock or other
securities or property in part before termination of the conversion or exchange right with respect
to the portion of the Security so selected, the converted or exchanged portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption. Securities which
have been converted or exchanged during a selection of Securities to be redeemed shall be treated
by the Trustee as Outstanding for the purpose of such selection.

     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 portions 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) that, in case any Security is to be redeemed in part only, 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, together (if applicable) with
accrued and unpaid interest, if any, thereon (subject, if applicable, to the provisos to the
first paragraph of Section 1106), 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

75

 

Date, are to be surrendered for payment of the Redemption Price and any accrued
interest and Additional Amounts pertaining thereto,

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

     (8) 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,

     (9) 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,

     (10) in the case of Securities of any series that are convertible or exchangeable into
Common Stock or other securities or property, the then current conversion or exchange price
or rate, the date or dates on which the right to convert or exchange the principal of the
Securities of such series to be redeemed will commence or terminate, as applicable, and the
place or places where and the Persons to whom such Securities may be surrendered for
conversion or exchange,

     (11) 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),
and

     (12) if the Redemption Price or any portion thereof shall be payable, at the option of
the Company or any Holders, in cash or in Common Stock or other securities or property (or a
combination thereof), a statement as to whether the Company has elected to pay the
Redemption Price in cash or Common Stock or other securities or property or a combination
thereof and, if applicable, the portion of the Redemption Price that is to be paid in cash,
Common Stock or other securities or property.

     A notice of redemption published 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 delivered at least 10 days before the date such
notice is to be given (unless a shorter period shall be acceptable to the Trustee), by the Trustee
in the name and at the expense of the Company.

     Section 1105. Deposit of Redemption Price.

     On or prior to noon (local time in New York City) on 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

76

 

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 for or in the Securities of such series) any accrued interest on and Additional Amounts with
respect to, all such Securities or portions thereof which are to be redeemed on that date, except
that, if the Securities of such series are convertible or exchangeable into Common Stock or other
securities or property, no such deposit shall be required with respect to any such Securities (or
portions thereof) which have been converted or exchanged prior to such Redemption Date.

     Section 1106. Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to be redeemed (except,
in the case of Securities which are convertible or exchangeable into Common Stock or other
securities or property, any such Securities which shall have been so converted or exchanged prior
to the applicable Redemption Date) shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, together with (unless otherwise provided with respect to the
Securities of such series pursuant to Section 301) accrued and unpaid interest, if any, thereon and
from and after such date (unless the Company shall default in the payment of the Redemption Price
and accrued interest, if any) 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, unless otherwise
provided in or pursuant to this Indenture, any accrued and unpaid interest thereon and Additional
Amounts with respect thereto to but excluding 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 or, at the option of the Company, after payment to the Trustee for the benefit of
the Company of, 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

77

 

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 or, if no rate is prescribed therefor in the
Security, at the rate of interest, if any, borne by such 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 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

SINKING FUNDS

     Section 1201. Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for the retirement of
Securities of a series that by its terms provides for such a sinking fund, except as otherwise
permitted or required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

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

78

 

     Section 1202. Satisfaction of Sinking Fund Payments with Securities.

     The Company may, in satisfaction of all or any part of any sinking fund payment with respect
to the Securities of any series to be made pursuant to the terms of such Securities (1) deliver
Outstanding Securities of such series (other than any of such Securities previously called for
redemption or any of such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all unmatured Coupons
appertaining thereto, and (2) apply as a credit Securities of such series which have been redeemed
either at the election of the Company pursuant to the terms of such series of Securities or through
the application of permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such Securities have not been previously so credited. Such Securities
shall be received and credited for such purpose by the Trustee at the Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the amount of such sinking
fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities
of any series in lieu of cash payments pursuant to this Section 1202, the principal amount of
Securities of such series to be redeemed in order to exhaust the aforesaid cash payment shall be
less than $100,000, the Trustee need not call Securities of such series for redemption, except upon
Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied
to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying
Agent shall at the request of the Company from time to time pay over and deliver to the Company any
cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the
Trustee of Securities of that series purchased by the Company having an unpaid principal amount
equal to the cash payment requested to be released to the Company.

     Section 1203. Redemption of Securities for Sinking Fund.

     Not less than 75 days prior to each sinking fund payment date for any series of Securities,
the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next
ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the
portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting of Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory
sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added
in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be
obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund
payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment
date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in Section 1104. Such
notice having been duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 1106 and 1107.

REPAYMENT AT THE OPTION OF HOLDERS

     Section 1301. 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 1301, 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 applicable 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.

     Unless otherwise expressly stated in this Indenture or pursuant to Section 301 with respect to
the Securities of any series or unless the context otherwise requires, all references in this
Indenture to the repayment of Securities at the option of the Holders thereof (and all references
of like import) shall be deemed to include a reference to the repurchase of Securities at the
option of the Holders thereof.

SECURITIES IN FOREIGN CURRENCIES

     Section 1401. 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 of any series in which not
all of such Securities are denominated in the same Currency, in the absence of any provision to the
contrary in or pursuant to this Indenture or the Securities of such series, any amount in respect
of any Security denominated in a Currency other than Dollars shall be treated for any such action,
determination 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 or distribution (or, if there shall be no
applicable record date, such other date reasonably proximate to the date of such distribution) as
the Company may specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

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

the Trustee to call a meeting of the Holders of Securities of such series for any purpose specified
in Section 1501, 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

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

shall be given as provided in Section 1502(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.

     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 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
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 at least 66-2/3% in principal amount of the Outstanding

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 1505. 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

82

 

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 1502(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. If
the Securities of such series are issuable in minimum denominations of less than $1,000, then a
Holder of such a Security in a principal amount of less than $1,000 shall be entitled to a fraction
of one vote which is equal to the fraction that the principal amount of such Security bears to
$1,000. 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 1502 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 1506. 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 1502 and, if applicable, Section 1504.
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

83

 

ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.
