Section 2.01. Form and Dating. The Securities and the Trustee’s certificate of
authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit
is incorporated in and made part of this Indenture. The Securities may have notations, legends or
endorsements required by law, stock exchange or automated quotation system rule or regulation or
usage. The Issuer shall provide any such notations, legends or endorsements to the Trustee in
writing. Each Security shall be dated the date of its authentication.

(a) Restricted Global Securities. All of the Securities are initially being offered
and sold through the Initial Purchasers to qualified institutional buyers as defined in Rule 144A
(collectively, “QIBs” or individually, each a “QIB”) in reliance on Rule 144A under
the Securities Act and shall be issued initially in the form of one or more Restricted Global
Securities, which shall be deposited on behalf of the purchasers of the securities represented
thereby with the Securities Custodian, as custodian for the depositary, The Depository Trust
Company (“DTC”, and such depositary, or any successor thereto, being hereinafter referred
to as the “Depositary”), and registered in the name of its nominee, Cede & Co. (or any
successor thereto), for the accounts of participants in the Depositary, duly executed by the Issuer
and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the
Restricted Global Securities may from time to time be increased or decreased by adjustments made on
the records of the Securities Custodian as hereinafter provided, subject in each case to compliance
with the Applicable Procedures.

(b) Global Securities In General. The Securities issued in global form shall be
substantially in the form of Exhibit A attached hereto (including the Global Security legend
thereon and the “Schedule of Exchanges of Securities” attached thereto). The Securities issued in
definitive form shall be substantially in the form of Exhibit A attached hereto (but without the
Global Security legend thereon and without the “Schedule of Exchanges of Securities” attached
thereto). Each Global Security shall represent such of the outstanding Securities as shall be
specified therein and each shall provide that it shall represent the aggregate amount of
outstanding Securities from time to time endorsed thereon and that the aggregate amount of
outstanding Securities represented thereby may from time to time be reduced or increased, as
appropriate, to reflect replacements, exchanges, purchases or redemptions of such Securities. Any
adjustment of the aggregate principal amount of a Global Security to reflect the amount of any
increase or decrease in the amount of outstanding Securities represented thereby shall be made by
the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12
and shall be made on the records of the Trustee and the Depositary.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights
under this Indenture with respect to any Global Security held on their behalf by the Depositary or
under the Global Security, and the Depositary (including, for this purpose, its nominee) may be
treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner
and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall (1) prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee
from giving effect to any written certification, proxy or other authorization furnished by the
Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of
customary practices governing the exercise of the rights of a Holder of any Security.

(c) Book Entry Provisions. The Issuer shall execute and the Trustee shall, in
accordance with this Section 2.01(c), authenticate and deliver initially one or more Global
Securities that (1) shall be registered in the name of the Depositary or its nominee, (2) shall be
held by the Trustee, as Securities Custodian for the Depositary or pursuant to the Depositary’s
instructions and (3) shall bear legends substantially to the following effect:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER,
EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE &
CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH
OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST
COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN
INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE
INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A
NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE
NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED
CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED IN
WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE
TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY
A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY
OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF
SUCH SUCCESSOR DEPOSITARY.”

Section 2.02. Execution and Authentication.

(a) The aggregate principal amount of Securities which may be authenticated and delivered
under this Indenture is limited to $1,750,000,000 aggregate principal amount; provided, that the
Issuer may, without the consent of the Holders, reopen the Securities and issue additional
Securities under this Indenture with the same terms and with the same CUSIP number as the
Securities issued under this Indenture on the initial Issue Date in an unlimited aggregate
principal amount; provided that no such additional Securities may be issued unless fungible with
the Securities issued under this Indenture on the initial Issue Date for U.S. Federal income tax
purposes. Any additional Securities would rank equally and ratably in right of payment with the
Securities issued under this Indenture on the initial Issue Date and would be treated as a single
series of debt securities for all purposes under this Indenture.

(b) An Officer of the Company in its capacity as general partner of the Issuer shall sign the
Securities for the Issuer by manual or facsimile signature. Typographic and other minor errors or
defects in any such facsimile signature shall not affect the validity or enforceability of any
Security that has been authenticated and delivered by the Trustee.

(c) If an Officer whose signature is on a Security no longer holds that office at the time the
Trustee authenticates the Security, the Security shall be valid nevertheless.

(d) A Security shall not be valid until an authorized signatory of the Trustee by manual
signature signs the certificate of authentication on the Security. The signature shall be
conclusive evidence that the Security has been authenticated under this Indenture. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered hereunder but never
issued and sold by the Issuer, and the Issuer shall deliver such Security to the Trustee for
cancellation as provided in Section 2.11, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered thereunder and shall never be entitled to the
benefits of this Indenture.

(e) The Trustee shall authenticate and make available for delivery Securities for issue upon
receipt of an Issuer Order. The Issuer Order shall specify the amount of Securities to be
authenticated, shall provide that all such Securities will be represented by a Restricted Global
Security and the date on which each original issue of Securities is to be authenticated.

(f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may
appoint an authenticating agent acceptable to the Issuer to authenticate Securities. An
authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by such agent. An
authenticating agent shall have the same rights as an Agent to deal with the Issuer or an Affiliate
of the Issuer.

Section 2.03. Registrar, Paying Agent and Exchange Agent.

(a) The Issuer shall maintain one or more offices or agencies where Securities may be
presented for registration of transfer or for exchange (each, a “Registrar”), one or more
offices or agencies where Securities may be presented for payment (each, a “Paying Agent”),
one or more offices or agencies where Securities may be presented for exchange (each, an
“Exchange Agent”) and one or more offices or agencies where notices and demands to or upon
the Issuer in respect of the Securities and this Indenture may be served. The Issuer will at all
times maintain a Paying Agent, Exchange Agent, Registrar and an office or agency where notices and
demands to or upon the Issuer in respect of the Securities and this Indenture may be served in the
United States. One of the Registrars (the “Primary Registrar”) shall keep a register of
the Securities and of their transfer and exchange.

(b) The Issuer shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall
implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the
Trustee of the name and address of any Agent not a party to this Indenture. If the Issuer fails to
maintain a Registrar, Paying Agent, Exchange Agent, or agent for service of notices and demands in
any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act
as such. The Issuer or any Affiliate of the Issuer may act as Paying Agent (except for the
purposes of Section 5.01 and Article 9).

(c) The Issuer hereby initially designates the Trustee as Paying Agent, Registrar, Securities
Custodian and Exchange Agent, and initially designates the Corporate Trust Office of the Trustee as
an office or agency where notices and demands to or upon the Issuer in respect of the Securities
and this Indenture shall be served.

Section 2.04. Intentionally Omitted.

Section 2.05. Lists of Holders of Securities. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it of the names and
addresses of Holders of Securities.

Section 2.06. Transfer and Exchange.

(a) Subject to compliance with any applicable additional requirements contained in Section
2.12, when a Security is presented to a Registrar with a request to register a transfer thereof or
to exchange such Security for an equal principal amount of Securities of other authorized
denominations, the Registrar shall register the transfer or make the exchange as requested;
provided, however, that every Security presented or surrendered for registration of transfer or
exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer
certificate each in the form included in Exhibit A, and completed in a manner satisfactory to the
Registrar and duly executed by the Holder thereof or its attorney duly authorized in writing. To
permit registration of transfers and exchanges, upon surrender of any Security for registration of
transfer or exchange at an office or agency maintained pursuant to Section 2.03, the Issuer shall
execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the
Registrar’s request. Any exchange or transfer shall be without charge, except that the Issuer or
the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto; provided that this sentence shall not apply to any
exchange pursuant to Section 2.10, 2.12(a), 3.04 or 4.04.

(b) In the event of any redemption in whole or any redemption in part, the Issuer shall not be
required to: (1) issue or register the transfer or exchange of any Security for another Security
during a period beginning at the opening of business 15 days before any selection of Securities for
redemption and ending at the close of business on the date of selection, or (ii) register the
transfer or exchange of any Security so selected for redemption, in whole or in part, for another
Security except the unredeemed portion of any Security being redeemed in part.

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

(d) Any Registrar appointed pursuant to Section 2.03 shall provide to the Trustee such
information as the Trustee may reasonably require in connection with the delivery by such Registrar
of Securities upon transfer or exchange of Securities.

(e) Each Holder of a Security agrees to indemnify the Issuer and the Trustee against any
liability that may result from the transfer, exchange or assignment of such Holder’s Security in
violation of any provision of this Indenture and/or applicable United States federal or state
securities law.

(f) 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 Agent Members or other 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.

Section 2.07. Replacement Securities.

(a) If any mutilated Security is surrendered to the Issuer, a Registrar or the Trustee, and
the Issuer, a Registrar and the Trustee receive evidence to their satisfaction of the destruction,
loss or theft of any Security, and there is delivered to the Issuer, the applicable Registrar and
the Trustee such security or indemnity as will be required by them to save each of them harmless,
then, in the absence of notice to the Issuer, such Registrar or the Trustee that such Security has
been acquired by a bona fide purchaser, the Issuer shall execute, and upon its written request the
Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of
any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount,
bearing a number not contemporaneously outstanding.

(b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become
due and payable, or is about to be purchased by the Issuer pursuant to Article 3, or exchanged
pursuant to Article 4, the Issuer in its discretion may, instead of issuing a new Security, pay,
purchase or exchange such Security, as the case may be.

(c) Upon the issuance of any new Securities under this Section 2.07, the Issuer may require
the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto as a result of any Securities, at the request of any Holder, being issued to a
Person other than such Holder and any other reasonable expenses (including the reasonable fees and
expenses of the Trustee or the Registrar) in connection therewith.

(d) Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated,
destroyed, lost or stolen Security shall constitute an original additional contractual obligation
of the Issuer, whether or not the mutilated, destroyed, lost or stolen Security shall be at any
time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

(e) The provisions of this Section 2.07 are (to the extent lawful) exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 2.08. Outstanding Securities.

(a) Securities outstanding (“Outstanding”) at any time are all Securities
authenticated by the Trustee, except for those canceled by it, those purchased pursuant to Article
3, those exchanged pursuant to Article 4, those redeemed by the Issuer pursuant to Article 11,
those delivered to the Trustee for cancellation or surrendered for transfer or exchange and those
described in this Section 2.08 as not outstanding.

(b) If a Security is replaced pursuant to Section 2.07, it ceases to be Outstanding unless the
Issuer receives proof satisfactory to it that the replaced Security is held by a bona fide
purchaser.

(c) If a Paying Agent (other than the Issuer or an Affiliate of the Issuer) holds in respect
of the outstanding Securities on a Change in Control Purchase Date, Redemption Date or the Final
Maturity Date money sufficient to pay the principal of, accrued interest, if any, on Securities (or
portions thereof) payable on that date, then on and after such Change in Control Purchase Date,
Redemption Date or Final Maturity Date, as the case may be, such Securities (or portions thereof,
as the case may be) shall cease to be outstanding and interest on them shall cease to accrue.

(d) Subject to the restrictions contained in Section 2.09, a Security does not cease to be
outstanding because the Issuer or an Affiliate of the Issuer holds the Security.

Section 2.09. Treasury Securities. In determining whether the Holders of the required
principal amount of Securities have concurred in any notice, direction, waiver or consent,
securities owned by the Issuer or any other obligor on the Securities or by any Affiliate of the
Issuer or of such other obligor shall be disregarded, except that, for purposes of determining
whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent,
only Securities which a Trust Officer of the Trustee with responsibility for this Indenture
actually knows are so owned shall be so disregarded. Securities so owned which have been pledged
in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the
Trustee the pledgee’s right so to act with respect to the Securities and that the pledgee is not
the Issuer or any other obligor on the Securities or any Affiliate of the Issuer or of such other
obligor.

Section 2.10. Temporary Securities. Until definitive Securities are ready for
delivery, the Issuer may prepare and execute, and, upon receipt of an Issuer Order, the Trustee
shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially
in the form of definitive securities but may have variations that the Issuer with the consent of
the Trustee considers appropriate for temporary Securities. Without unreasonable delay, the Issuer
shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for
temporary Securities.

After the preparation of definitive Securities, the temporary Securities shall be exchangeable
for definitive Securities of such series upon surrender of the temporary Securities to a Registrar,
without charge to the Holder. Upon surrender for cancellation of any one or more temporary
Securities, the Issuer shall execute and the Trustee shall authenticate and deliver in exchange
therefor one or more definitive Securities, of any authorized denominations and of like tenor.
Until so exchanged, Holders of temporary Securities shall be entitled to all of the benefits of
this Indenture.

Section 2.11. Cancellation. The Issuer at any time may deliver Securities to the
Trustee for cancellation. The Registrar, the Paying Agent and the Exchange Agent shall forward to
the Trustee or its agent any Securities surrendered to them for transfer, exchange, purchase or
payment. The Trustee and no one else shall cancel, in accordance with its standard procedures, all
Securities surrendered for transfer, exchange, purchase, payment or cancellation and shall dispose
of the canceled Securities in accordance with its customary procedures or deliver the canceled
Securities to the Issuer. All Securities which are purchased, redeemed or otherwise acquired by
the Issuer or any of its Subsidiaries prior to the Final Maturity Date pursuant to Article 3 shall
be delivered to the Trustee for cancellation, and the Issuer may not hold or resell such Securities
or issue any new Securities to replace any such Securities or any Securities that any Holder has
exchanged pursuant to Article 4.

Section 2.12. Legend; Additional Transfer and Exchange Requirements.

(a) If Securities are issued upon the transfer, exchange or replacement of Securities such
Securities shall bear the legends set forth on the forms of Securities attached as Exhibit A
relating to restrictions on transfer of the Securities (collectively, the “Restrictive
Legend”).

(b) A Global Security may not be transferred, in whole or in part, to any Person other than
the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person
may be registered; provided that the foregoing shall not prohibit any transfer of a Security that
is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a
Security to any Person shall be effective under this Indenture or the Securities unless and until
such Security has been registered in the name of such Person. Notwithstanding any other provisions
of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be
made only in accordance with this Section 2.12.

(c) Subject to Section 2.12(b), every Security shall be subject to the restrictions on
transfer provided in the Restrictive Legend. Whenever any Restricted Security other than a
Restricted Global Security is presented or surrendered for registration of transfer or in exchange
for a Security registered in a name other than that of the Holder, such Security must be
accompanied by a certificate in substantially the form set forth in Exhibit A, dated the date of
such surrender and signed by the Holder of such Security, as to compliance with such restrictions
on transfer. The Registrar shall not be required to accept for such registration of transfer or
exchange any Security not so accompanied by a properly completed certificate.

As used in Sections 2.12(c), the term “transfer” encompasses any sale, pledge, transfer,
hypothecation or other disposition of any Security.

(d) The provisions below shall apply only to Global Securities:

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

(2) Notwithstanding any other provisions of this Indenture or the Securities, a Global
Security shall not be exchanged in whole or in part for a Security registered, and no
transfer of a Global Security in whole or in part shall be registered in the name of any
Person other than the Depositary or one or more nominees thereof; provided that a Global
Security may be exchanged for securities registered in the names of any person designated by
the Depositary in the event that (A) the Depositary has notified the Issuer that it is
unwilling or unable to continue as Depositary for such Global Security or such Depositary
has ceased to be a “clearing agency” registered under the Exchange Act, and a successor
Depositary is not appointed by the Issuer within 90 days after receiving such notice or
becoming aware that the Depositary has ceased to be a “clearing agency,” or (B) an Event of
Default has occurred and is continuing with respect to the Securities. Any Global Security
exchanged pursuant to subclause (A) above shall be so exchanged in whole and not in part,
and any Global Security exchanged pursuant to subclause (B) above may be exchanged in whole
or from time to time in part as directed by the Depositary. Any Security issued in exchange
for a Global Security or any portion thereof shall be a Global Security; provided further
that any such Security so issued that is registered in the name of a Person other than the
Depositary or a nominee thereof shall not be a Global Security.

(3) Securities issued in exchange for a Global Security or any portion thereof shall be
issued in definitive, fully registered form, shall have an aggregate principal amount equal
to that of such Global Security or portion thereof to be so exchanged, shall be registered
in such names and be in such authorized denominations as the Depositary shall designate and
shall bear the applicable legends provided for herein. Any Global Security to be exchanged
in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard
to any Global Security to be exchanged in part, either such Global Security shall be so
surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its
nominee with respect to such Global Security, the principal amount thereof shall be reduced,
by an amount equal to the portion thereof to be so exchanged, by means of an appropriate
adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the
Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the
order of the Depositary or an authorized representative thereof.

(4) Subject to clause (6) of this Section 2.12(d), the registered Holder may grant
proxies and otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is entitled to take
under this Indenture or the Securities.

(5) In the event of the occurrence of any of the events specified in clause (2) of this
Section 2.12(d), the Issuer will promptly make available to the Trustee a reasonable supply
of Certificated Securities in definitive, fully registered form, in the event that any such
Security so issued is registered in the name of a Person other than the Depositary.

(6) Neither Agent Members nor any other Persons on whose behalf Agent Members may act
shall have any rights under this Indenture with respect to any Global Security registered in
the name of the Depositary or any nominee thereof, or under any such Global Security, and
the Depositary or such nominee, as the case may be, may be treated by the Issuer, the
Trustee and any agent of the Issuer or the Trustee as the absolute owner and Holder of such
Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by the
Depositary or such nominee, as the case may be, or impair, as between the Depositary, its
Agent Members and any other Person on whose behalf an Agent Member may act, the operation of
customary practices of such Persons governing the exercise of the rights of a Holder of any
Security.

(7) At such time as all interests in a Global Security have been converted, canceled or
exchanged for Securities in certificated form, such Global Security shall, upon receipt
thereof, be canceled by the Trustee in accordance with standing procedures and instructions
existing between the Depositary and the Securities Custodian, subject to Section 2.11 of
this Indenture. At any time prior to such cancellation, if any interest in a Global
Security is converted, canceled or exchanged for Securities in certificated form, the
principal amount of such Global Security shall, in accordance with the standing procedures
and instructions existing between the Depositary and the Securities Custodian, be
appropriately reduced, and an endorsement shall be made on such Global Security, by the
Trustee or the Securities Custodian, at the direction of the Trustee, to reflect such
reduction.

(e) Until the expiration of the holding period applicable to sales thereof under Rule 144(k)
under the Securities Act (or any successor provision thereto), any stock certificate representing
Common Stock issued upon exchange of any Security shall bear the restrictive legend required to be
included with a Restricted Security, unless such Common Stock have been sold pursuant to a
registration statement that has been declared effective under the Securities Act (and which
continues to be effective at the time of such transfer) or transferred in compliance with Rule 144
(or any successor provision thereto), or unless otherwise agreed by the Issuer in writing with
written notice thereof to the transfer agent.

Any such Common Stock as to which such restrictions on transfer shall have expired in
accordance with their terms or as to which the conditions for removal of the restrictive legend set
forth therein have been satisfied may, upon surrender of the certificates representing such Common
Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be
exchanged for a new certificate or certificates for a like number of Common Stock, which shall not
bear the restrictive legend required by this section.

Section 2.13. CUSIP Numbers. The Issuer in issuing the Securities may use one or more
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in
notices of purchase as a convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Securities or
as contained in any notice of a purchase and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such purchase shall not be affected by
any defect in or omission of such numbers. The Issuer will promptly notify the Trustee of any
change in the “CUSIP” numbers.

ARTICLE 3

REPURCHASE

Section 3.01. Repurchase at Option of Holders upon a Change in Control.

(a) If a Change in Control occurs at any time prior to April 15, 2012, a Holder of Securities
shall have the right, at its option, to require the Issuer to repurchase such Holder’s Securities
not previously called for redemption, in whole or in part (in principal amounts of $1,000 or an
integral multiple thereof) for cash equal to the Change in Control Purchase Price, subject to
satisfaction by or on behalf of the Holder of the requirements set forth below. If a Change in
Control occurs on or after April 15, 2012, no Holder will have the right to require the Issuer to
purchase any Securities, except as provided in Section 3.02 hereof.

(b) Within 15 days after the occurrence of a Change in Control, the Issuer shall provide
written notification to the Holders of the Change in Control and of the repurchase right arising as
a result of the Change in Control (the “Issuer Notice”). The Issuer Notice shall also be
delivered to the Trustee. The notice shall include a form of Change in Control Purchase Notice to
be completed by the Holder containing the information contemplated by Section 3.01(c) and shall
state:

(1) the date of such Change in Control and the clause in the definition of “Change in
Control” herein under which such Change in Control falls;

(2) the date by which the Change in Control Purchase Notice must be delivered to the
Paying Agent;

(3) the date on which the Issuer will repurchase Securities in connection with a Change
in Control, which must be not less than 20 days nor more than 30 days after the date of the
Issuer Notice (such date, the “Change in Control Purchase Date”);

(4) the Change in Control Purchase Price;

(5) the name and address of the Trustee, the Paying Agent and the Exchange Agent;

(6) that Securities in respect of which a Change in Control Purchase Notice is provided
by a Holder shall not be exchangeable;

(7) that Securities must be surrendered to the Paying Agent (which surrender may, if
applicable, be effected through the facilities of the Depository) to collect payment of the
Change in Control Purchase Price;

(8) that the Change in Control Purchase Price for any Security as to which a Change in
Control Purchase Notice has been duly given will be paid within five Business Days after the
later of the Change in Control Purchase Date or the time at which such Securities are
surrendered for repurchase;

(9) that, unless the Issuer defaults in making payment of the Change in Control
Purchase Price, such Securities shall cease to be Outstanding and interest on such
Securities shall cease to accrue and all rights of the Holders of such Securities shall
terminate on and after the Change in Control Purchase Date; and

(10) the CUSIP number of the Securities.

The Issuer shall also disseminate a press release through Dow Jones & Company, Inc. or
Bloomberg Business News announcing the occurrence of such Change in Control and publish on the
Company’s website, or through such other public medium as the Issuer shall deem appropriate at such
time.

(c) A Holder may exercise its rights specified in this Section 3.01 upon delivery of a written
notice of such Holder’s exercise of its repurchase right (a “Change in Control Purchase
Notice”) to the Trustee (or any Paying Agent) at any time prior to the close of business on the
second Business Day prior to the Change in Control Purchase Date, stating:

(1) if such Securities are in certificated form, the certificate number(s) of the
Securities which the Holder will deliver to be repurchased;

(2) the portion of the principal amount of the Securities to be repurchased, in
multiples of $1,000, provided that the remaining principal amount of Securities is in an
authorized denomination; and

(3) that such Security shall be repurchased pursuant to the applicable provisions
hereof and of the Securities.

The Trustee (or any Paying Agent) shall promptly notify the Issuer in writing of the receipt
by it of any Change in Control Purchase Notice.

Book-entry transfer of Securities in book-entry form in compliance with the Applicable
Procedures or delivery of Securities in certificated form (together with all necessary
endorsements) to the Paying Agent at the offices of the Paying Agent and delivery of such Security
shall be conditions to the receipt by the Holder of the Change in Control Purchase Price therefor.
Holders electing to require the Issuer to repurchase Securities must effect such transfer or
delivery to the Paying Agent prior to the Change in Control Purchase Date to receive payment of the
Change in Control Purchase Price.

(d) A Change in Control Purchase Notice is irrevocable and may not be withdrawn.

(e) On or before 11:59 a.m. (New York City time) on the Change in Control Purchase Date, the
Issuer shall deposit with the Paying Agent money sufficient to pay the aggregate Change in Control
Purchase Price of the Securities to be purchased pursuant to this Section 3.01. If the Paying
Agent holds, in accordance with the terms of the Indenture, money sufficient to pay the Change in
Control Purchase Price of such Securities on the Change in Control Purchase Date or the Business
Day following the Change in Control Repurchase Date, then, on and after such date, such Securities
shall cease to be Outstanding and interest on such Securities shall cease to accrue and all rights
of the Holders of such Securities shall terminate (other than the right to receive the Change in
Control Purchase Price after delivery or transfer of the Securities). Such will be the case
whether or not book entry transfer of the Securities in book entry form is made and whether or not
Securities in certificated form, together with the necessary endorsements, are delivered to the
Paying Agent.

(f) Notwithstanding the foregoing, no Securities may be repurchased by the Issuer in
accordance with the provisions of this Section 3.01 if there has occurred and is continuing an
Event of Default with respect to the Securities and the principal amount of the Securities has been
accelerated and such acceleration has not been rescinded on or prior to such dates.

(g) The Paying Agent will promptly return to the respective Holders thereof any Securities
with respect to which a Change in Control Purchase Notice has been withdrawn in compliance with
this Indenture.

Section 3.02. Repurchase of Securities at the Option of Holders. 

(a) A Holder of Securities has the right, at such Holder’s option, to require the Issuer to
repurchase such Holder’s Securities, in whole or in part (in principal amounts of $1,000 or an
integral multiple thereof) for cash equal to the Repurchase Price on April 15, 2012, April 15, 2017
and April 15, 2022 (each, a “Repurchase Date”).

(b) A Holder shall provide written notification to Paying Agent of its intent to require the
Issuer to purchase such Holder’s Securities no earlier than the opening of business 60 Business
Days prior to the relevant Repurchase Date and no later than the close of business on the fifth
Business Day prior to the relevant Repurchase Date (the “Repurchase Notice”) stating:

(1) if such Securities are in certificated form, the certificate number(s) of the
Securities which the Holder will deliver to be repurchased (if such Securities are not
certificated, the Repurchase Notice must comply with Applicable Procedures);

(2) the portion of the principal amount of the Securities to be repurchased, in
integral multiples of $1,000, provided that the remaining principal amount of Securities is
in an authorized denomination; and

(3) that such Security shall be repurchased pursuant to the applicable provisions
hereof and of the Securities.

The Issuer shall also disseminate a press release through Dow Jones & Company, Inc. or
Bloomberg Business News containing the information included on the Repurchase Notice or publish
such information or on the Company’s website, or through such other public medium as the Issuer
shall deem appropriate at such time.

(c) A Repurchase Notice may be withdrawn in whole by a Holder by means of a written notice of
withdrawal delivered to the office of the Paying Agent prior to 5:00 p.m., New York City time, on
the second Business Day prior to the Repurchase Date specifying:

(1) the principal amount of Securities being withdrawn, in integral multiples of
$1,000,

(2) if such Securities are in certificated form, the certificate number(s) of the
Securities being withdrawn; and

(3) the principal amount of Securities, if any, that remains subject to Repurchase
Notice, which must be an integral multiple of $1,000.

If the Securities subject to the notice of withdrawal are in book-entry form, the above
notices must also comply with the Applicable Procedures.

(d) A Holder must either effect book-entry transfer or deliver the Securities, together with
necessary endorsements, to the office of the Paying Agent after delivery of the Repurchase Notice
to receive payment of the Repurchase Price.

(e) On or before 11:59 a.m. (New York City time) on the Repurchase Date, the Issuer shall
deposit with the Paying Agent money sufficient to pay the aggregate Repurchase Price of the
Securities to be purchased pursuant to this Section 3.02. If the Paying Agent holds, in accordance
with the terms of the Indenture, money sufficient to pay the Repurchase Price of such Securities on
the Repurchase Date or the Business Day following the Repurchase Date, then, on and after such
date, such Securities shall cease to be Outstanding and interest on such Securities shall cease to
accrue and all rights of the Holders of such Securities shall terminate (other than the right to
receive the Repurchase Price after delivery or transfer of the Securities). Such will be the case
whether or not book entry transfer of the Securities in book entry form is made and whether or not
Securities in certificated form, together with the necessary endorsements, are delivered to the
Paying Agent.

Section 3.03. Repayment to the Issuer. To the extent that the aggregate amount of
cash deposited by the Issuer pursuant to Section 3.01 or 3.02 exceeds the aggregate Change in
Control Purchase Price or the Repurchase Price of the Securities or portions thereof that the
Issuer is obligated to purchase, then promptly after the Change in Control Purchase Date or the
Repurchase Date, as applicable, the Trustee or a Paying Agent, as the case may be, shall return any
such excess cash to the Issuer.

Section 3.04. Securities Purchased in Part. Any Security that is to be purchased only
in part shall be surrendered at the office of a Paying Agent, and promptly after the Change in
Control Purchase Date or the Repurchase Date, as applicable, the Issuer shall execute and the
Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a
new Security or Securities, of such authorized denomination or denominations as may be requested by
such Holder (which must be equal to $1,000 principal amount or any integral thereof), in aggregate
principal amount equal to, and in exchange for, the portion of the principal amount of the Security
so surrendered that is not purchased.

Section 3.05. Repurchase of Securities by Third Parties. The Issuer may arrange for a
third party to purchase any Securities for which the Issuer has received a valid Repurchase Notice
that is not withdrawn, in the manner and otherwise in compliance with the requirements set forth
herein. If a third party purchases any Securities under these circumstances, then interest will
continue to accrue on those Securities and those Securities will continue to be Outstanding after
the Repurchase Date. The third party subsequently may resell those purchased Securities to other
Holders, and those Securities will be fungible with all other Securities then Outstanding.

Section 3.06. Purchase of Securities in Open Market. The Issuer may from time to time
repurchase the Securities in open market purchases or negotiated transactions at varying prices
without prior notice to Holders. Any Security that the Issuer purchases or a third party purchases
may, to the extent permitted by applicable law and subject to restrictions contained in the
purchase agreement with the Initial Purchasers, be reissued or resold or may, at the Issuer’s or
such third party’s option, be surrendered to the Trustee for cancellation. Any Securities
surrendered for cancellation may not be reissued or resold and will be canceled promptly in
accordance with Section 2.11.

ARTICLE 4

EXCHANGE

Section 4.01. Right to Exchange. Subject to the restrictions on ownership of Common
Stock as set forth in Section 4.12 hereof and the conditions set forth in this Article 4, a Holder
of any Securities not previously redeemed or repurchased shall have the right, at such Holder’s
option, to exchange each $1,000 principal amount of Securities, into cash, shares of Common Stock
or a combination of cash and shares of Common Stock, at the Issuer’s option, by surrender of such
Securities so to be exchanged in whole or in part, together with any required funds, under the
circumstances and in the manner described in this Article 4, (a) at any time on or after January
15, 2027 and prior to the close of business on the second Business Day immediately prior to the
Final Maturity Date; and (b) upon occurrence of any of the following events:

(i) Exchange Upon Satisfaction of Market Price Condition. During any Measurement Period
(and only during such period) prior to the second Business Day prior to the Final Maturity
Date, if the Closing Sale Price of the Common Stock for at least 20 Trading Days in the
period of 30 consecutive Trading Days beginning on the first day of such Measurement Period
is more than 130% of the Exchange Price per share of Common Stock in effect on the first day
of such Measurement Period.

The Issuer, or the Trustee at the request of the Issuer, (or other Exchange Agent
appointed by the Issuer) shall, on behalf of the Issuer, determine on a daily basis during
the time period specified in this Section 4.01(b)(i) whether the Securities shall be
exchangeable as a result of the occurrence of an event specified in this clause (i) and, if
the Securities shall be so exchangeable, the Trustee (or other Exchange Agent appointed by
the Issuer) shall promptly deliver to the Issuer and the Trustee (if the Trustee is not the
Exchange Agent) written notice thereof.

(ii) Exchange Upon Satisfaction of Trading Price Condition. During the five consecutive
Trading Day period following any 20 consecutive Trading Days in which the average of the
Trading Prices per $1,000 principal amount of Securities during such 20 consecutive Trading
Day period was less than 98% of the average of the Closing Sale Prices of the Common Stock
for such period, multiplied by the average of the Applicable Exchange Rates for each Trading
Day in effect during such 20 consecutive Trading Day period.

The Trustee shall have no obligation to determine the Trading Price of the Securities
unless the Issuer shall have requested such determination, and the Issuer shall have no
obligation to make such request unless a Holder provides the Issuer with reasonable evidence
that the Trading Price per $1,000 principal amount of Securities would be less than 98% of
the Closing Sale Price per share of Common Stock multiplied by the Applicable Exchange Rate,
whereupon the Issuer shall instruct the Trustee to determine the Trading Price of the
Securities beginning on the next Trading Day and on each successive Trading Day until the
Trading Price per $1,000 principal amount of Securities is greater than or equal to 98% of
the Closing Sale Price per share of Common Stock multiplied by the Applicable Exchange Rate.
If the Issuer does not request a determination from the Trustee when so required by the
Holders, the Trading Price of the Securities shall be deemed to be less than 98% of the
Closing Sale Price per share of Common Stock multiplied by the Applicable Exchange Rate on
each day that the Issuer fails to do so.

(iii) Exchange Upon Notice of Redemption. Such Securities have been called for
redemption, in which event a Holder may surrender for exchange any of the Securities called
for redemption at any time prior to the close of business on the second Business Day
immediately prior to Redemption Date even if the Securities are not otherwise exchangeable
at such time.

(iv) Exchange Upon Delisting of the Common Stock. At any time beginning on the first
Business Day after the Common Stock shall have ceased to be listed on a U.S. national or
regional securities exchange for a period of 30 consecutive Trading Days.

(v) Exchange Upon Specified Transactions. The Company elects to:

(1) distribute to all holders of Common Stock rights, warrants or options entitling
them to purchase, for a period of up to 45 days after the issuance thereof, shares of Common
Stock at a price per share that is less than the Closing Sale Price of per share of Common
Stock on the Trading Day immediately preceding the declaration date of such distribution; or

(2) distribute to all holders of Common Stock the Issuer’s assets, debt securities or
rights to purchase securities of the Issuer, which distribution has a per share value
exceeding 15% of the Closing Sale Price of the Common Stock on the Trading Day immediately
preceding the declaration date of such distribution,

in which event, the Issuer must notify the Holders at least 20 calendar days prior to the
Ex-Dividend date for such distribution, giving Holders the right to surrender their
Securities for exchange at any time until the earlier of the close of business on the
Business Day immediately preceding the Ex-Dividend Date or an announcement by the Issuer
that such distribution will not take place; provided, however, that a Holder may not
exercise the right to exchange if the Holder may participate, on an as-exchanged basis, in
the distribution without exchange of the Securities.

In addition, if the Company is a party to a consolidation, merger or binding share exchange
pursuant to which Common Stock would be converted into cash, securities or other property
(the “Reference Property”), a Holder may surrender Securities for exchange at any
time from and after the date that is 15 Business Days prior to the anticipated effective
date of the transaction until five Business Days after the actual date of such transaction.
The Issuer shall notify Holders as promptly as practicable following the date the Issuer
publicly announces such transaction (but in no event less than 15 days prior to the
anticipated effective date of the transaction). If the Issuer is a party to a
consolidation, merger or binding share exchange pursuant to which Common Stock would be
exchanged into Reference Property, then at the effective time of the transaction, the
Holder’s right to exchange the Securities for Common Stock shall be changed into a right to
exchange the Securities into the kind and amount of Reference Property that the Holder would
have received if the Holder had exchanged its Securities immediately prior to the effective
time of the transaction.

If a Holder exchanges its Securities pursuant to this Section 4.01(b)(v) and, if such Holder
shall be entitled to an adjustment for additional Common Stock as provided by Section 4.03
hereof, the exchange of the Securities shall settle after the effective time of the
transaction. If a Holder exchanges its Securities at any time following the effective time
of the transaction, the amount will be paid based on the kind and amount of Reference
Property.

A Security in respect of which a Holder has delivered a Change in Control Purchase Notice or a
Repurchase Notice, as the case may be, exercising such Holder’s right to require the Issuer to
repurchase such Security pursuant to Section 3.01 or Section 3.02 hereof may be exchanged only if
such Change in Control Purchase Notice or a Repurchase Notice, as the case may be, is withdrawn in
accordance with the Section 3.01(d) or 3.02(c) prior to 5:00 p.m., New York City time, on the
second Business Day immediately prior to the Change in Control Purchase Date or the Repurchase
Date, as applicable.

A Holder of Securities is not entitled to any rights of a Holder of Common Stock until such
Holder has exchanged its Securities and received upon exchange thereof Common Stock.

Section 4.02. Exercise of Exchange Right; No Adjustment for Interest or Dividends. In
order to exercise the exchange right with respect to any Security in certificated form, the Issuer
must receive at the office or agency of the Issuer maintained for that purpose in the City of New
York or, at the option of such Holder, the Corporate Trust Office, such Security with the original
or facsimile of the form entitled “Exchange Notice” on the reverse thereof (the “Exchange Notice”),
duly completed and signed manually or by facsimile, together with such Securities duly endorsed for
transfer, accompanied by the funds, if any, required by this Section 4.02. Such notice shall also
state the name or names (with address or addresses) in which the certificate or certificates for
Common Stock that shall be issuable on such exchange shall be issued, and shall be accompanied by
transfer or similar taxes, if required pursuant to Section 4.07.

To exchange the Securities, a Holder must (a) complete and manually sign the Exchange Notice
on the reverse of the Security (or complete and manually sign a facsimile of such notice) and
deliver such notice to the Exchange Agent at the office maintained by the Exchange Agent for such
purpose, (b) with respect to Securities that are in certificated form, surrender the Securities to
the Exchange Agent, (c) furnish appropriate endorsements and transfer documents if required by the
Exchange Agent and (d) pay any transfer or similar tax, if required. The date on which the Holder
satisfies all such requirements shall be deemed to be the date on which the applicable Securities
shall have been tendered for exchange (the “Exchange Date”)

Whether the Securities to be exchanged are held in book-entry or certificated form, the
Exchange Notice will require the Holder to certify that it or the Person on whose behalf the
Securities are being exchanged is a qualified institutional buyer within the meaning of Rule 144A
under the Securities Act.

Upon surrender of a Security for exchange by a Holder, such Holder shall deliver to the Issuer
cash equal to the amount that the Issuer is required to deduct and withhold under applicable law in
connection with the exchange; provided, however, if the Holder does not deliver such cash, the
Issuer may deduct and withhold from the amount of consideration otherwise deliverable to such
Holder the amount required to be deducted and withheld under applicable law (and not otherwise
delivered by the Holder in cash).

If the Issuer is required to deliver Common Stock upon settlement in accordance with Sections
4.03 and 4.11, if applicable, not later than the third Trading Day following the end of the
Applicable Exchange Measurement Period, after satisfaction of the requirements for exchange set
forth above, subject to compliance with any restrictions on transfer if shares of Common Stock
issuable on exchange are to be issued in a name other than that of the Holder (as if such transfer
were a transfer of the Security or Securities (or portion thereof) so exchanged), and in accordance
with the time periods set forth in this Article 4, the Issuer shall deliver to such Holder at the
office or agency maintained by the Issuer for such purpose pursuant to Section 2.03 hereof, (i) a
certificate or certificates for the number of full shares of Common Stock issuable upon the
exchange of such Security or portion thereof as determined by the Issuer in accordance with the
provisions of Sections 4.03 and 4.11 and (ii) a check or cash in respect of any fractional interest
in respect of a share of Common Stock arising upon such exchange, calculated by the Issuer as
provided in Section 4.06. The cash, and, if applicable, a certificate or certificates for the
number of full shares of Common Stock into which the Securities are exchanged (and cash in lieu of
fractional shares) will be delivered to an exchanging holder after satisfaction of the requirements
for exchange set forth above, in accordance with this Section 4.02 and Sections 4.03 (if
applicable) and 4.11.

The Person in whose name any certificate or certificates for Common Stock shall be issuable
upon such exchange shall be deemed to have become on said date the holder of record of the shares
represented thereby, to the extent permitted by applicable law; provided that any such surrender on
any date when the stock transfer books of the Company shall be closed shall constitute the Person
in whose name the certificates are to be issued as the record holder thereof for all purposes on
the next succeeding day on which such stock transfer books are open, but such exchange shall be at
the Exchange Rate in effect on the Exchange Date.

Any Security or portion thereof surrendered for exchange during the period from 5:00 p.m., New
York City time, on the record date for any interest payment date to 5:00 p.m., New York City time,
on the applicable Interest Payment Date shall be accompanied by payment, in immediately available
funds or other funds acceptable to the Issuer, of an amount equal to the interest otherwise payable
on such Interest Payment Date on the principal amount being exchanged; provided that no such
payment need be made (1) if a Holder exchanges its Securities in connection with a redemption and
the Issuer has specified a Redemption Date that is after a record date and on or prior to the
Business Day immediately succeeding the next Interest Payment Date, or (2) if a Holder exchanges
its Securities in connection with a Change in Control and the Issuer has specified a Change in
Control Purchase Date that is after a record date and on or prior to the corresponding Interest
Payment Date. Except as otherwise provided above in this paragraph, no payment or other adjustment
shall be made for interest accrued on any Security exchanged or for dividends on any shares issued
upon the exchange of such Security as provided in this Section 4.02.

Upon the exchange of an interest in a Global Security, the Trustee (or other Exchange Agent
appointed by the Issuer), or the Custodian at the direction of the Trustee (or other Exchange Agent
appointed by the Issuer), shall make a notation on such Global Security as to the reduction in the
principal amount represented thereby. The Issuer shall notify the Trustee in writing of any
exchanges of Securities effected through any Exchange Agent other than the Trustee.

Upon the exchange of a Security, a Holder will not receive any cash payment of interest
(unless such exchange occurs between a Regular Record Date and the Interest Payment Date to which
it relates as described above) and the Issuer will not adjust the Exchange Rate to account for
accrued and unpaid interest. The Issuer’s delivery to the Holder of cash or shares of Common Stock
will be deemed to satisfy the Issuer’s obligation with respect to such Security. Accordingly, the
accrued but unpaid interest attributable to the period from the Issue Date of the Security to the
Exchange Date, with respect to the exchanged Security, shall not be deemed canceled, extinguished
or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery
of cash and, if applicable, Common Stock (together with the cash payment, if any in lieu of
fractional shares) in exchange for the Security being exchanged pursuant to the provisions hereof.

In case any Security of a denomination greater than $1,000 shall be surrendered for partial
exchange, and subject to Section 2.02 hereof, the Issuer shall execute and the Trustee shall
authenticate and deliver to the Holder of the Security so surrendered, without charge to the
Holder, a new Security or Securities in authorized denominations in an aggregate principal amount
equal to the unexchanged portion of the surrendered Security.

Section 4.03. Exchange Rate Adjustment After Certain Change in Control.

(a) Subject to the provisions hereof, if a Holder elects to exchange its Securities following
the consummation of any transaction described in clause (1) of the definition of Change in Control
on or prior to April 15, 2012 (the “Additional Shares Change in Control”) and a Holder
elects to exchange Securities in connection with such transaction pursuant to Section 4.01(b)(v),
the Issuer will increase the Applicable Exchange Rate for the Securities surrendered for exchange
by a number of additional shares of Common Stock described below (the “Change in Control Event
Shares”). An exchange of Securities will be deemed for these purposes to be “in connection
with” such Additional Shares Change in Control if the notice of exchange of the Securities is
received by the Exchange Agent on or after the date which is 15 days prior to the anticipated
effective date of the Additional Shares Change in Control and, on or prior to the fifth Business
Day following the effective date of the Additional Shares Change in Control (or if earlier and to
the extent applicable, the close of business on the second Trading Day immediately preceding the
day on which the Issuer is required to repurchase Securities pursuant to 3.01 hereof).

(b) The number of Change in Control Event Shares shall be determined by reference to the table
in paragraph (e) below and shall be based on the date on which the Additional Shares Change in
Control becomes effective (the “Effective Date”) and the price (the “Stock Price”)
paid per share of Common Stock in such transaction. If the holders of Common Stock receive only
cash in the relevant Change in Control transaction, the Stock Price will equal the cash amount paid
per share of Common Stock. In all other cases, the Stock Price will equal the average of the
Closing Sale Prices of the Common Stock on the ten consecutive Trading Days up to but excluding the
Effective Date.

(c) Notwithstanding anything herein to the contrary, in no event shall the total number of
shares of Common Stock issuable upon exchange exceed 14.6526 per $1,000 principal amount of
Securities, subject to adjustment in the same manner as the Exchange Rate as set forth in Section
4.04 hereof.

(d) The Stock Prices set forth in the first row of the table below shall be adjusted as of any
date on which the Exchange Rate of the Securities is adjusted pursuant to Section 4.04. The
adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment,
multiplied by a fraction, (i) the numerator of which is the Exchange Rate immediately prior to the
adjustment giving rise to the Stock Price adjustment and (ii) the denominator of which is the
Exchange Rate as so adjusted. In addition, the number of additional shares of Common Stock will be
subject to adjustment in the same manner as the Exchange Rate set forth under Section 4.04 hereof.

(e) Subject to paragraph (c) of this Section 4.03, the following table sets forth the Stock
Price and number of Change in Control Event Shares issuable per $1,000 principal amount of
Securities:

The exact Stock Price and Effective Dates may not be set forth in the table, in which case:

(1) if the Stock Price is between two Stock Price amounts in the table or the Effective
Date is between two Effective Dates in the table, the number of Change in Control Event
Shares will be determined by a straight-line interpolation between the number of Change in
Control Event Shares set forth for the higher and lower Stock Prices and the earlier and
later Effective Dates, as applicable, based on a 365-day year;

(2) if the Stock Price is in excess of $165.00 per share of Common Stock, subject to
adjustment (the “Make Whole Cap”), no Change in Control Event Shares will be issued
upon exchange; and

(3) if the Stock Price is less than $65.72 per share of Common Stock, subject to
adjustment (the “Make Whole Floor”), no Change in Control Event Shares will be
issued upon exchange.

The Make Whole Cap and Make Whole Floor shall be adjusted as of any date on which the Exchange
Rate of the Securities is adjusted pursuant to Section 4.04 hereof

Section 4.04. Adjustment of Exchange Rate. The Exchange Rate shall be adjusted from time
to time by the Issuer as follows:

(a) If the Company issues shares of Common Stock as a dividend or distribution on the Common
Stock to all holders of Common Stock, or if the Company effects a share split or share combination,
the Exchange Rate will be adjusted based on the following formula:

ER1 = ER0 × OS1/OS0

where

ER0 = the Exchange Rate in effect immediately prior to the Ex-Dividend
Date for such dividend or distribution or the effective date of such share split or
share combination, as applicable;

ER1 = the Exchange Rate in effect on and after the Ex-Dividend Date for
such dividend or distribution or the effective date of such share split or share
combination, as applicable;

OS0 = the number of shares of Common Stock outstanding on the Ex-Dividend
Date for such dividend or distribution, or the effective date of such share split or
share combination, as applicable; and

OS1 = the number of shares of Common Stock outstanding on the Ex-Dividend
Date for such dividend or distribution or the effective date of such share split or
share combination, as applicable, as if such dividend, distribution, split or
combination occurred at that time.

If any dividend or distribution described in this paragraph (a) is declared but not so paid or
made, the Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if
such dividend or distribution had not been declared.

(b) If the Company issues to all holders of Common Stock any rights, warrants, options or
other securities entitling them for a period of not more than 45 days after the date of issuance
thereof to subscribe for or purchase Common Stock or securities convertible into Common Stock
within 45 days after the issuance thereof, in either case at an exercise price per share of Common
Stock or a conversion price per share less than the Closing Sale Price of Common Stock on the
Business Day immediately preceding the time of announcement of such issuance, the Exchange Rate
will be adjusted based on the following formula (provided that the Exchange Rate will be readjusted
to the extent that such rights, warrants, options, or other securities or convertible securities
are not exercised or converted prior to the expiration of the exercisability or convertibility
thereof):

ER1 = ER0 × (OS0 + X)/(OS0 + Y)

where

ER0 = the Exchange Rate in effect immediately prior to the Ex-Dividend
Date for such issuance;

ER1 = the Exchange Rate in effect on and after the Ex-Dividend Date for
such issuance;

OS0 = the number of shares of Common Stock outstanding immediately prior
to the Ex-Dividend Date for such issuance;

X = the number of shares of Common Stock issuable pursuant to such rights, warrants,
options, other securities or convertible securities; and

Y = the number of shares of Common Stock equal to the quotient of (A) the aggregate
price payable to exercise such rights, warrants, options, other securities or
convertible securities and (B) the average of the Closing Sale Prices of the Common
Stock for the ten consecutive Trading Days prior to the Business Day immediately
preceding the date of announcement for the issuance of such rights, warrants,
options, other securities or convertible securities.

For purposes of this paragraph (b), in determining whether any rights, warrants, options,
other securities or convertible securities entitle the Holders to subscribe for or purchase or
exercise a conversion right for Common Stock at less than the average Closing Sale Price of the
Common Stock, and in determining the aggregate exercise or conversion price payable for such Common
Stock, there shall be taken into account any consideration received by the Company for such rights,
warrants, options, other securities or convertible securities and any amount payable on exercise or
conversion thereof, with the value of such consideration, if other than cash, to be determined by
the Board of Directors.

(c) If the Company distributes shares of capital stock, evidences of indebtedness or other
assets or property of the Company to all holders of Common Stock, excluding:

(1) dividends, distributions, rights, warrants, options, other securities or
convertible securities referred to in paragraph (a) or (b) above;

(2) dividends or distributions paid exclusively in cash; and

(3) Spin-Offs described below in this paragraph (c),

then the Exchange Rate will be adjusted based on the following formula:

ER1 = ER0 × SP0/(SP0 – FMV)

where

ER0 = the Exchange Rate in effect immediately prior to the Ex-Dividend
Date for such distribution;

ER1 = the Exchange Rate in effect on and after the Ex-Dividend Date for
such distribution;

SP0 = the average of the Closing Sale Prices of the Common Stock for the
ten consecutive Trading Days prior to the Business Day immediately preceding the
Ex-Dividend Date for such distribution; and

FMV = the fair market value (as determined in good faith by the Board of Directors)
of the shares of capital stock, evidences of indebtedness, assets or property
distributed with respect to each outstanding share of Common Stock on the
Ex-Dividend Date for such distribution;

With respect to an adjustment pursuant to this paragraph (c), where there has been a payment
of a dividend or other distribution on Common Stock or shares of capital stock of any class or
series, or similar equity interest, of or relating to a subsidiary or other business unit of the
Company (a “Spin-Off”), the Exchange Rate will be adjusted based on the following formula:

ER1 = ER0 × (FMV0 + MP0)/MP0

where

ER0 = the Exchange Rate in effect immediately prior to the effective date
of the Spin-Off;

ER1 = the Exchange Rate in effect on and after the effective date of the
Spin-Off;

FMV0 = the average of the Closing Sale Prices of the capital stock or
similar equity interest distributed to holders of Common Stock applicable to one
share of Common Stock over the first ten consecutive Trading Days after the
effective date of the Spin-Off; and

MP0 = the average of the Closing Sale Prices of the Common Stock over the
first ten consecutive Trading Days after the effective date of the Spin-Off.

If any such dividend or distribution described in this paragraph (c) is declared but not paid
or made, the Exchange Rate shall be readjusted to be the Exchange Rate that would then be in effect
if such dividend or distribution had not been declared.

(d) If following the date of original issuance of the Securities, the Company makes any cash
dividend or distribution to all holders of Common Stock in aggregate amount that, together with
other cash dividends or distributions during such quarterly fiscal period, on a per share basis,
exceeds $0.45 (the “Reference Dividend”) the Exchange Rate will be adjusted based on the
following formula:

ER1 = ER0 × SP0 /(SP0 – C)

where

ER0 = the Exchange Rate in effect immediately prior to the Ex-Dividend
Date for such distribution;

ER1 = the Exchange Rate in effect on and after the Ex-Dividend Date for
such distribution;

SP0 = the average of the Closing Sale Prices of the Common Stock over the
period of the ten consecutive Trading Days ending on the Business Day immediately
preceding the Ex-Dividend Date for such distribution; and

C = the amount in cash per share that the Company distributes to holders of Common
Stock during such quarterly fiscal period in excess of the Reference Dividend.

If any dividend or distribution described in this paragraph (d) is declared but not so paid or
made, the Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if
such dividend or distribution had not been declared.

The Reference Dividend amount is subject to adjustment in a manner inversely proportional to
adjustments to the Exchange Rate; provided that no adjustment will be made to the Reference
Dividend for any adjustment to the Exchange Rate under this paragraph (d).

(e) If the Company or any of its subsidiaries makes a payment in respect of a tender offer or
exchange offer for shares of Common Stock to the extent that the cash and value of any other
consideration included in the payment per share of Common Stock exceeds the Closing Sale Price of a
share of Common Stock on the Trading Day next succeeding the last date on which tenders or
exchanges may be made pursuant to such tender offer or exchange offer (the “Expiration Time”), the
Exchange Rate will be adjusted based on the following formula:

ER1 = ER0 × (AC + (SPI ×
OS1))/(SP1 × OS0)

where

ER0 = the Exchange Rate in effect on the date such tender offer or
exchange offer expires;

ER1 = the Exchange Rate in effect on the day next succeeding the date
such tender offer or exchange offer expires;

AC = the aggregate value of all cash and any other consideration (as determined by
the Board of Directors) paid or payable for the shares of Common Stock purchased in
such tender or exchange offer;

OS0 = the number of shares of Common Stock outstanding immediately prior
to the date such tender offer or exchange offer expires;

OS1 = the number of shares of Common Stock outstanding immediately after
such tender or exchange offer expires (after giving effect to the purchase or
exchange of shares of Common Stock pursuant to such tender offer or exchange offer);
and

SP1 = the average of the Closing Sale Price of the Common Stock for the
10 consecutive Trading Days commencing on the Trading Day next succeeding the date
such tender offer or exchange offer expires.

If the application of the foregoing formula would result in a decrease in the Exchange Rate,
no adjustment to the Exchange Rate will be made.

If the Company or one of its subsidiaries is obligated to purchase Common Stock pursuant to
any such tender offer or exchange offer, but it or such subsidiary is permanently prevented by
applicable law from effecting any such purchases or all such purchases are rescinded, the Exchange
Rate shall be readjusted to be the Exchange Rate that would be in effect if such tender offer or
exchange offer had not been made.

(f) Notwithstanding the foregoing, in no event shall the adjustments arising under this
Section 4.04 cause the Exchange Rate to exceed 14.6526, subject to the adjustments in clauses (a),
(b) and (c) of this Section 4.04.

(g) If the Company adopts a shareholder rights plan while any Securities remain outstanding,
Holders of Securities will receive, upon an exchange of Securities for shares of Common Stock, in
addition to Common Stock, rights under such shareholder rights plan unless, prior to exchange, the
rights have expired, terminated or been redeemed or unless the rights have separated from the
Common Stock. If the rights provided for in the rights plan adopted by the Company have separated
from the Common Stock in accordance with the provisions of the applicable shareholder rights
agreement so that Holders of Securities would not be entitled to receive any rights in respect of
Common Stock issuable upon exchange of the Securities, the Exchange Rate will be adjusted at the
time of separation as if the Company had distributed, to all holders of Common Stock, shares of
capital stock, evidences of indebtedness or other assets or property pursuant to Section 4.04(c)
hereof, subject to readjustment upon the subsequent expiration, termination or redemption of the
rights. In lieu of any such adjustment, the Company may amend such applicable shareholder rights
agreement to provide that upon exchange of Securities, the Holders will receive, in addition to
Common Stock issuable upon such exchange, the rights which would have attached to such Common Stock
if the rights had not become separated from the Common Stock under such shareholders rights plan.

(h) In addition to the adjustments pursuant to paragraphs (a) through (f) above, the Issuer
may increase the Exchange Rate in order to avoid or diminish any income tax to holders of the
capital stock of the Company resulting from any dividend or distribution of capital stock (or
rights to acquire shares of Common Stock) or from any event treated as such for income tax
purposes. The Issuer may also, from time to time, to the extent permitted by applicable law
increase the Exchange Rate by any amount for any period if the Issuer has determined that such
increase would be in the best interests of the Issuer or the Company. If the Issuer makes such
determination, it will be conclusive and the Issuer shall mail to Holders a notice of the increased
Exchange Rate at least 15 days prior to the date the increased Exchange Rate takes effect in
accordance with applicable law and such notice shall state the increased exchange rate and the
period during which it will be in effect.

The Issuer shall not make any adjustment to the Exchange Rate if Holders are permitted to
participate in the dividend, distribution or transaction, on an as-exchanged basis, in the
transactions in this Section 4.04.

(i) Notwithstanding anything to the contrary contained herein, the applicable Exchange Price
and Exchange Rate will not be adjusted upon certain events, including but not limited to:

(1) the issuance of any shares of Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on securities of the Issuer
or those of the Company and the investment of additional optional amounts in shares of
Common Stock under any plan;

(2) the issuance of any shares of Common Stock or options or rights to purchase those
 shares pursuant to any present or future employee, director, trustee or consultant benefit
plan, employee agreement or arrangement or program of the Issuer or the Company;

(3) the issuance of any shares of Common Stock pursuant to any option, warrant, right,
or exercisable, exchangeable or convertible security outstanding as of the date the
Securities were first issued;

(4) a change in the par value of the Common Stock;

(5) accumulated and unpaid dividends or distributions; and

(6) as a result of a tender offer solely to holders of less than 100 shares of Common
Stock; and

(7) for the avoidance of doubt, the issuance of limited partnership units by the Issuer
and the issuance of the Common Stock or the payment of cash upon redemption thereof.

(j) No adjustment in the applicable Exchange Price will be required unless the adjustment
would require an increase or decrease of at least 1% of the applicable Exchange Price. If the
adjustment is not made because the adjustment does not change the Exchange Price by at least 1%,
then the adjustment that is not made will be carried forward and taken into account in any future
adjustment. All required calculations will be made to the nearest cent or 1/1000th of a share, as
the case may be. Notwithstanding the foregoing, upon exchange of the Securities, upon required
repurchases of the Securities in connection with a Change in Control pursuant to Section 3.01, upon
redemption of the Securities pursuant to Section 11.01 and five Business Days prior to the Final
Maturity Date, all adjustments not previously made shall be made. Except as specifically described
above, the applicable Exchange Price shall not be subject to adjustment in the case of the issuance
of any shares of Common Stock or the Company’s preferred shares, or securities exchangeable for or
convertible into common stock or the Company’s preferred shares.

(k) Whenever the Exchange Rate is adjusted as herein provided, the Company or the Issuer shall
as promptly as reasonably practicable file with the Trustee and any Exchange Agent other than the
Trustee an Officer’s Certificate setting forth the Exchange Rate after such adjustment and setting
forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such
certificate, the Company or the Issuer shall prepare a notice of such adjustment of the Exchange
Rate setting forth the adjusted Exchange Rate and the date on which each adjustment becomes
effective and shall mail such notice of such adjustment of the Exchange Rate to the Holders within
20 Business Days of the Effective Date of such adjustment. Failure to deliver such notice shall not
affect the legality or validity of any such adjustment.

(l) For purposes of this Section 4.04, the number of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of Common Stock.

(m) For purposes of this Section 4.04, “record date” shall mean, with respect to any dividend,
distribution or other transaction or event in which the Holders of Common Stock have the right to
receive any cash, securities or other property or into which the Common Stock (or other applicable
security) is exchanged or converted into any combination of cash, securities or other property, the
date fixed for determination of shareholders entitled to receive such cash, security or other
property (whether or not such date is fixed by the Board of Directors or by statute, contract or
otherwise).

Section 4.05. Exchange Rate. The initial Exchange Rate for the Securities is 11.2712
Common Stock per each $1,000 principal amount of the Securities, subject to adjustment as provided
in Sections 4.03 and 4.04 (herein called the “Exchange Rate”).

Section 4.06. Cash Payments in Lieu of Fractional Shares. No fractional shares of
Common Stock or scrip certificates representing fractional shares shall be issued upon exchange of
Securities. If more than one Security shall be surrendered for exchange at one time by the same
Holder, the number of full shares of Common Stock that shall be issuable upon exchange shall be
computed on the basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered. If any fractional share of Common Stock
would be issuable upon the exchange of any Security or Securities, the Issuer shall make an
adjustment and payment therefor in cash to the Holder of Securities at a price equal to the Closing
Sale Price of the Common Stock on the last day of the Applicable Exchange Measurement Period.

Section 4.07. Taxes on Shares Issued. If a Holder exchanges Securities, the Issuer
will pay any documentary stamp or similar issue or transfer tax due on the delivery of Common Stock
upon the exchange, if any, unless the tax is due because the Holder requests the shares to be
delivered to a person other than the Holder, in which case the Holder will pay the tax. Shares of
Common Stock shall not be issued or delivered unless all taxes and duties, if any, payable by the
Holder have been paid.

Section 4.08. Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental
Requirements; Listing of Common Stock. The Issuer shall provide, free from preemptive rights,
out of its authorized but unissued shares or shares held in treasury, sufficient Common Stock to
provide for the exchange of the Securities as required by this Indenture from time to time as such
Securities are presented for exchange.

The Issuer covenants that all Common Stock issued upon exchange of Securities will upon issue
be fully paid and non-assessable by the Company and free from all taxes, liens and charges with
respect to the issue thereof, provided that if certain of the possible adjustments to the exchange
price are made, a Holder shall be deemed to have a received a distribution from the Issuer even
though such Holder has not received any cash or property as a result of such adjustments, the
Issuer intends to withhold Federal income tax (in the case of U.S. Alien Note Holders) on any
deemed distribution from the Issuer from cash payments of interest otherwise payable on the
Securities and payments upon a redemption or exchange of the Securities.

The Issuer covenants that, if any Common Stock to be provided for the purpose of exchange of
Securities hereunder require registration with or approval of any governmental authority under any
federal or state law before such shares may be validly issued upon exchange, the Company shall, as
expeditiously as practicable, secure such registration or approval, as the case may be, provided,
however, that Common Stock provided for exchange hereunder need not be registered under the U.S.
Federal securities laws and each recipient of such Common Stock shall have the rights set forth in
the Registration Rights Agreement.

Section 4.09. Responsibility of Trustee. The Trustee and any other Exchange Agent
shall not at any time be under any duty or responsibility to any Holder to determine the Exchange
Rate or whether any facts exist which may require any adjustment of the Exchange Rate, or with
respect to the nature or extent or calculation of any such adjustment when made, or with respect to
the method employed, or herein or in any supplemental indenture provided to be employed, in making
the same. The Trustee and any other Exchange Agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any Common Stock, or of any capital stock, other
securities or other assets or property, which may at any time be issued or delivered upon the
exchange of any Security; and the Trustee and any other Exchange Agent make no representations with
respect thereto. Neither the Trustee nor any Exchange Agent shall be responsible for any failure of
the Issuer to issue, transfer or deliver any Common Stock or stock certificates or other securities
or property or cash upon the surrender of any Security for the purpose of exchange or to comply
with any of the duties, responsibilities or covenants of the Issuer contained in this Article 4.
Without limiting the generality of the foregoing, neither the Trustee nor any Exchange Agent shall
be under any responsibility to determine the correctness of any provisions contained in any
supplemental indenture entered into pursuant to Section 4.03 relating either to the kind or amount
of shares of capital stock or other securities or other assets or property (including cash)
receivable by Holders upon the exchange of their Securities after any event referred to in such
Section 4.03 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 8.01(f), may accept as conclusive evidence of the correctness of any such provisions,
and shall be protected in relying upon, the Officer’s Certificate (which the Issuer shall be
obligated to file with the Trustee prior to the execution of any such supplemental indenture) with
respect thereto. The Trustee shall not at any time be under any duty or responsibility to any
holder of Securities to determine the accuracy of the method employed in calculating the Trading
Price or whether any facts exist which may require any adjustment of the Trading Price.

Section 4.10. Notice to Holders Prior to Certain Actions. In case:

(a) the Company shall declare a dividend (or any other distribution) on the Common Stock that
would require an adjustment in the Exchange Rate pursuant to Section 4.04; or

(b) the Company shall authorize the granting to the holders of all or substantially all of the
Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other
rights or warrants; or

(c) of any reclassification or reorganization of the Common Stock (other than a subdivision or
combination of its outstanding Common Stock, or a change in par value, or from par value to no par
value, or from no par value to par value), or of any consolidation, combination, merger or share
exchange to which the Issuer or the Company is a party and for which approval of any stockholders
of the Company is required, or of the sale or transfer of all or substantially all of the assets of
the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company;

the Issuer shall cause to be filed with the Trustee a notice stating (x) the date on which a record
is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a
record is not to be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution or rights are to be determined, or (y) the date on which
such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding
up is expected to become effective or occur, and the date as of which it is expected that holders
of Common Stock of record shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up. Failure to give such notice, or any defect therein, shall
not affect the legality or validity of such dividend, distribution, reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

Section 4.11. Settlement upon Exchange. (a)  Upon exchange of any Securities,
subject to Sections 4.01, 4.02 and this Section 4.11, the Issuer shall satisfy its obligation upon
exchange (the “Exchange Obligation”) by payment and delivery on or prior to the third Trading Day
immediately following the last day of the Applicable Exchange Measurement Period, at the Issuer’s
option, of cash, shares of Common Stock or a combination of cash and shares of Common Stock for
each $1,000 aggregate principal amount of Securities tendered for exchange in accordance with their
terms, as follows:

(1) Share Settlement. If the Issuer elects to satisfy the entire Exchange Obligation
in shares of Common Stock, then the Issuer shall deliver, for each Trading Day in the
Applicable Exchange Measurement Period, a number of shares of Common Stock equal to the
Applicable Exchange Rate divided by 20.

(2) Cash Settlement. If the Issuer elects to satisfy the entire Exchange Obligation in
cash, then the Issuer shall deliver, for each Trading Day in the Applicable Exchange
Measurement Period, cash in an amount equal to the Daily Exchange Value.

(3) Combined Settlement. If the Issuer elects to satisfy a portion of the Exchange
Obligation in cash (expressed either as a dollar amount or as a percentage of the Daily
Exchange Value, the “Partial Cash Amount”) and a portion in shares of Common Stock,
then the Issuer shall deliver, for each Trading Day in the Applicable Exchange Measurement
Period, (A) the lesser of (x) such Partial Cash Amount divided by 20 or, if expressed as a
percentage of the exchange obligation, such Partial Cash Amount will be calculated as a
percentage of the Daily Exchange Value (the “Daily Partial Cash Amount”) and (y) the
Daily Exchange Value, plus (B) a number of shares of Common Stock equal to (x) the excess,
if any, of the Daily Exchange Value over such Daily Partial Cash Amount divided by (y) the
Daily VWAP of the Common Stock for such day.

(b) The Issuer shall initially elect the Partial Cash Amount to be the principal amount of the
Securities and shall deliver any amount of the aggregate Daily Exchange Value in excess of the
principal amount of the Securities, if any, in Common Stock; provided that such election is
revocable and the Issuer may make any future election revocably or irrecovably. Upon changing such
election, the Issuer shall promptly (i) issue a press release and post such information on the
Company’s website or otherwise publicly disclose such information and (ii) provide written notice
to the Trustee of the Securities in the manner contemplated herein. The Issuer may not make any
change to such election subsequent to January 15, 2027. No change in election on or after the
Exchange Date shall affect the exchanging Holder with respect to Securities submitted for exchange
by such Holder.

(c) The Issuer will deliver cash in lieu of any fractional share of Common Stock issuable in
connection with the payment of the shares of the Common Stock on the last day of the Applicable
Exchange Measurement Period.

Section 4.12. Ownership Limit. Notwithstanding any other provision of the Securities,
no Holders of Securities shall be entitled to receive shares of Common Stock upon an exchange of
Securities to the extent that receipt of such shares of Common Stock would cause such Holder
(together with such Holder’s Affiliates) to exceed the ownership limit contained the Company’s
certificate of incorporation. Any attempted exchange of Securities in excess of such ownership
limit, in the absence of such a waiver, shall be void to the extent of such excess, and the related
Securities or portions thereof shall be returned by the Issuer to the Holder as promptly as
practicable. The Issuer shall have no further obligation to the Holder with respect to such voided
exchange and such Securities will be treated as if they had not been submitted for exchange. A
Holder of returned Securities may resubmit such Securities for exchange at a later date subject to
compliance with the terms hereof and the ownership limitations described in this Section 4.12.
Notwithstanding the foregoing provisions of this Section 4.12, in the event a Holder attempts to
exchange Securities but is prevented from doing so as a result of the ownership limitation, the
Issuer may, at its option, pay cash to such Holder upon such exchange as provided herein. 

Section 4.13. Calculation in Respect of Securities. Except as otherwise specifically
stated herein or in the Securities, all calculations to be made in respect of the Securities shall
be the obligation of the Issuer. All calculations made by the Issuer or its agent as contemplated
pursuant to the terms hereof and of the Securities shall be made in good faith and be final and
binding on the Securities and the Holders absent manifest error. The Issuer shall provide a
schedule of calculations to the Trustee, and the Trustee shall be entitled to rely upon the
accuracy of the calculations by the Issuer without independent verification. The Trustee shall
forward calculations made by the Issuer to any Holder of Securities upon request.

ARTICLE 5

COVENANTS

Section 5.01. Payment of Securities.

(a) The Issuer shall promptly make all payments in respect of the Securities on the dates and
in the manner provided in the Securities and this Indenture. Any payment hereunder shall be
considered paid on the applicable date due if on such date the Trustee or the Paying Agent holds,
in accordance with this Indenture, money sufficient to pay all such amounts then due. Subject to
Section 4.02, accrued and unpaid interest on any Security that is payable, and is punctually paid
or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that
Security is registered at the close of business on the Regular Record Date for such interest at the
office or agency of the Issuer maintained for such purpose. The Issuer shall, to the fullest
extent permitted by law, pay interest in immediately available funds on overdue principal amount
and interest at the annual rate borne by the Securities compounded semiannually, which interest
shall accrue from the date such overdue amount was originally due to the date payment of such
amount, including interest thereon, has been made or duly provided for. All such overdue interest
shall be payable on demand.

(b) Payment of the principal of and interest, if any, on the Securities shall be made at the
office or agency of the Issuer maintained for that purpose or at the Corporate Trust Office of the
Trustee in such coin or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that at the option of the
Trustee on behalf of the Issuer payment of interest may be made by check mailed to the address of
the Person entitled thereto as such address appears in the Register; provided further that a Holder
with an aggregate principal amount in excess of $5,000,000 will be paid by wire transfer in
immediately available funds at the election of such Holder if such Holder has provided wire
transfer instructions to the Trustee at least 10 Business Days prior to the payment date. Any wire
transfer instructions received by the Trustee will remain in effect until revoked by the Holder.

(c) The Issuer shall comply with any requirement to withhold any taxes with respect to (i)
payments made pursuant to the terms of this Indenture (including without limitation, interest and
original issue discount), (ii) redemption payments, (iii) any exchange of the Securities and (iv)
any deemed payment or distribution made with respect to the Securities as a result of an adjustment
to the Exchange Rate. To the extent the Issuer determines in its sole discretion that the Issuer
is required to withhold any taxes with respect to a deemed payment or distribution with respect to
a Security on account of an adjustment to the Exchange Rate, the Issuer shall withhold such amount
from payments otherwise due hereunder to the holder of such Security and report such withholding to
the Holders affected if and as required by law. Any amount withheld by the Issuer pursuant to this
Section 5.01(c) with respect to a Security shall be treated for all purposes of this Indenture as
if it had been paid directly to the holder of such Security.

Section 5.02. Money for Securities Payments to be Held in Trust. If the Issuer or its
Affiliate shall at any time act as its own Paying Agent with respect to the Securities, it will, on
or before each due date of the Persons entitled thereto a sum sufficient to pay the principal and
any interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of
as herein provided and will promptly notify the Trustee of its action or failure to so act.

(a) Whenever the Issuer shall have one or more Paying Agents for any series of Securities, it
will, prior to each due date of the principal of or any interest on any Securities of that series,
deposit with a Paying Agent a sum sufficient to pay such amount and (unless such Paying Agent is
the Trustee) the Issuer will promptly notify the Trustee of its action or failure to act.

(b) The Issuer will cause each Paying Agent for any series of Securities other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provision of this Section, that such Paying Agent will, during the
continuance of any default by the Issuer (or any other obligor upon the Securities of that series)
in the making of any payment in respect of the Securities of that series, upon the written request
of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

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

(d) Any money deposited with the Trustee or the Paying Agent, or then held by the Issuer in
trust for the payment of the principal of or any interest on any Security of any series and
remaining unclaimed for two years after such principal or interest has become due or payable shall
be paid to the Issuer or (if then held by the Issuer) shall be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Issuer
for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such
trust money, and all liability of the Issuer, as trustee thereof, shall thereupon cease; provided
that the Trustee or such Paying Agent, before being required to make any such repayment, may at the
expense of the Issuer cause to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in New York, New York, 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, any unclaimed balance of such money then remaining
will be repaid to the Issuer.

Section 5.03. Reports. So long as the Issuer is not subject to the information
requirements of Section 13 or 15(d) of the Exchange Act, the Issuer shall furnish to holders of
Securities and prospective purchasers thereof the information with respect to the Issuer required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act in order to permit compliance
with Rule 144A in connection with resales of such Securities.

Section 5.04. Compliance Certificates. The Issuer shall deliver to the Trustee,
within 120 days after the end of each fiscal year of the Issuer (beginning with the fiscal year
ending on December 31, 2007), an Officer’s Certificate as to the signer’s knowledge of the Issuer’s
compliance with all terms, conditions and covenants on its part contained in this Indenture and
stating whether or not the signer knows of any Default or Event of Default. If such signer knows
of such a Default or Event of Default, the Officer’s Certificate shall describe the Default or
Event of Default and the efforts to remedy the same. For the purposes of this Section 5.04,
compliance shall be determined without regard to any grace period or requirement of notice provided
pursuant to the terms of this Indenture.

Section 5.05. Further Instruments and Acts. Upon request of the Trustee, the Issuer
will execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purposes of this Indenture.

Section 5.06. Maintenance of Existence as a Limited Partnership. Subject to Article
6, the Issuer will do or cause to be done all things necessary to preserve and keep in full force
and effect its existence as a limited partnership.

Section 5.07. Stay, Extension and Usury Laws. The Issuer covenants (to the extent
that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law
which would prohibit or forgive the Issuer from paying all or any portion of the principal of or
accrued but unpaid interest, if any, on the Securities as contemplated herein, wherever enacted,
now or at any time hereafter in force, or which may affect the covenants or the performance of this
Indenture, and the Issuer (to the extent it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law and covenants that it will not, by resort to any such law, hinder,
delay or impede the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

Section 5.08. Calculation of Original Issue Discount. The Issuer shall file with the
Trustee promptly at the end of each calendar year a written notice specifying the amount of
original issue discount (including daily rates and accrual periods) accrued on the Securities as of
the end of such year, but only if as of the end of such year Securities issued at an original issue
discount are then outstanding.

Section 5.09. Maintenance of Office or Agency. The Issuer will maintain an office or
agency of the Trustee, Registrar and Paying Agent where securities may be presented or surrendered
for payment, where Securities may be surrendered for registration of transfer, purchase or
redemption and where notices and demands to or upon the Issuer in respect of the Securities and
this Indenture may be served. The Corporate Trust Office shall initially be one such office or
agency for all of the aforesaid purposes. The Issuer shall give prompt written notice to the
Trustee of the location, and of any change in the location, of any such office or agency (other
than a change in the location of the office of the Trustee). If at any time the Issuer 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
address of the Trustee set forth in Section 12.01. The Issuer may also from time to time designate
one or more other offices or agencies where the Securities 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 Issuer of its obligation to
maintain an office or agency.

ARTICLE 6

CONSOLIDATION; MERGER; CONVEYANCE; TRANSFER OR LEASE

Section 6.01. Issuer and Company May Consolidate, Etc., Only on Certain Terms. Each
of the Issuer and the Company shall not (a) consolidate with or merge with or into any other Person
or sell, convey, lease or transfer the Issuer’s properties and assets substantially as an entirety
to any other Person in any one transaction or series of related transactions, or (b) permit any
Person to consolidate with or merge into the Issuer, unless: 

(1) in the case of a merger or consolidation, the Company or the Issuer, as applicable,
is the surviving person or if the Company or the Issuer, as applicable, is not the surviving
person, the surviving person formed by such consolidation or into which the Company or the
Issuer, as applicable, is merged or the person to which the Company’s or the Issuer’s, as
applicable, properties and assets are so transferred shall be an entity organized and
existing under the laws of the United States of America, any state thereof or the District
of Columbia and shall execute and deliver to the trustee a supplemental indenture expressly
assuming, in the case of a transaction involving the Issuer, the payment when due of the
principal of and interest on the Securities and the performance of the Issuer’s other
covenants under this Indenture; and

(2) in either case, immediately after giving effect to such transaction, no Default or
Event of Default shall have occurred and be continuing.

In the event that the Issuer or the Company, as the case may be, is not the continuing entity,
then, for purposes of above, the references to the Issuer or the Company shall be deemed to refer
to the successor entity.

Section 6.02. Successor Substituted. Upon any consolidation of the Issuer with, or
merger of the Issuer into, any other Person or any sale, conveyance, lease or transfer of the
Issuer’s properties and assets substantially as an entirety to any other Person, in each case in
accordance with Section 6.01, the successor Person formed by such consolidation or into which the
Issuer is merged or to which such sale, conveyance, lease or transfer is made shall succeed to, and
be substituted for, and may exercise every right and power of, the Issuer under this Indenture with
the same effect as if such successor Person had been named as the Issuer herein, and thereafter,
except for obligations the predecessor Person may have under a supplemental indenture, the
predecessor Person shall be relieved of all obligations and covenants under this Indenture and the
Securities.

ARTICLE 7

DEFAULT AND REMEDIES

Section 7.01. Events of Default. “Event of Default,” wherever used herein with
respect to the Securities, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected by operation of
law or pursuant to any judgment, decree or order of any court or any order, rule, regulation of any
administrative or governmental body):

(1) default by the Issuer in the payment of any interest upon any Security when it
becomes due and payable, and continuance of such default for a period of 30 days; or

(2) default by the Issuer in the payment of principal of or any premium, if any, on any
Securities on the Final Maturity Date; or

(3) default by the Issuer or the Company in the performance, or breach, of any covenant
of the Issuer in this Indenture for the benefit of the Securities and continuance of such
default or breach for a period of 90 days after there has been given, by registered or
certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee of at least
25% in principal amount of the Securities a written notice specifying such default or breach
and requiring it to be remedied and stating that such notice is a “Notice of Default”
hereunder; or

or evidenced any indebtedness for money borrowed by the Issuer having an aggregate principal
amount outstanding of at least $50,000,000, whether such indebtedness now exists or shall
hereafter be created, which default (A) shall constitute a failure to pay any portion of the
principal of such indebtedness when due and payable after the expiration of any applicable
grace period with respect thereto or (B) shall have resulted in such indebtedness becoming
or being declared due and payable prior to the date on which it would otherwise have become
due and payable, without, in the case of Clause (A), such indebtedness having been
discharged or without, in the case of Clause (B), such indebtedness having been discharged
or such acceleration having been rescinded or annulled, in each such case within a period of
10 days after there shall have been given, by registered or certified mail, to the Issuer by
the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in principal
amount of the Securities a written notice specifying such default and requiring the Issuer
to cause such indebtedness to be discharged or cause such acceleration to be rescinded or
annulled, as the case may be, and stating that such notice is a “Notice of Default”
hereunder; provided, that, subject to the provisions of Sections 8.01 and 8.02 hereof, the
Trustee shall not be deemed to have knowledge of such default unless either (A) a
Responsible Officer of the Trustee shall have knowledge of such default or (B) the Trustee
shall have received written notice thereof from the Issuer, from any Holder, from the holder
of any such indebtedness or from the trustee under any such mortgage, indenture or other
instrument; or

under any applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law or (B) a decree or order adjudging the Issuer or the Company a bankrupt or
insolvent, or approving as properly filed a petition seeking reorganization, arrangement,
adjustment or composition of or in respect of the Issuer or the Company under any applicable
Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee,
sequestrator or other similar official of the Issuer or the Company or of any substantial
part of its property, or ordering the winding up or liquidation of its affairs, and the
continuance of any such decree or order for relief or any such other decree or order
unstayed and in effect for a period of 60 consecutive days; or

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

Section 7.02. Acceleration. If an Event of Default (other than an Event of Default
specified in clause (7) or (8) of Section 7.01) occurs and is continuing, then in every such case
the Trustee, upon receipt of a request made in accordance with Section 12.01, from the Holders of
not less than 25% in principal amount of the Securities then outstanding, may, by written notice to
the Issuer and the Company (and to the Trustee if given by the Holders), declare the principal
amount through the date of declaration on all the Securities to be immediately due and payable.
Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, shall
be due and payable immediately. If an Event of Default specified in clause (7) or (8) of Section
7.01 occurs and is continuing, the principal amount of the Securities shall automatically, become
immediately due and payable without any declaration or other act on the part of the Trustee or any
Holders of Securities. At any time after such a declaration of acceleration with respect to the
Securities has been made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a
majority in principal amount of the Securities, by written notice to the Issuer, the Company and
the Trustee, may rescind and annul such declaration and its consequences if:

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

(B) all overdue installments of interest on all outstanding Securities,

(C) the principal of any outstanding Securities which have become due otherwise
than by such declaration of acceleration and interest thereon at the rate or rates
borne by or provided for in the Securities,

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

(E) 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

(2) all Events of Default with respect to the Securities, other than the nonpayment of
the principal of (or specified portion thereof) or interest on the Securities which have
become due solely by such declaration of acceleration, have been cured or waived as provided
in Section 7.04.

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

	 
	 	 
	Section 7.03.

	 	Other Remedies.
	
 
	 	 

(a) If an Event of Default occurs and is continuing, the Trustee may, but shall not be
obligated to, pursue any available remedy by proceeding at law or in equity to collect payment of
the principal amount and accrued and unpaid interest, if any, on the Securities or to enforce the
performance of any provision of the Securities or this Indenture.

(b) The Trustee may maintain a proceeding even if it does not possess any of the Securities or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder
in exercising any right or remedy accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive
of any other remedy. All available remedies are cumulative to the extent permitted by applicable
law.

Section 7.04. Waiver of Defaults and Events of Default. (a)  Subject to
Sections 7.07 and 10.02, the Holders of no less than a majority in aggregate principal amount of
the Securities then outstanding by written notice to the Trustee may waive an past Default or Event
of Default and its consequences, except an uncured Default or Event of Default in the payment of
the principal of or any accrued but unpaid interest on any Security, or any Default or Event of
Default in respect of any provision of this Indenture or the Securities which, under Section 10.02,
cannot be modified or amended without the consent of the Holder of each Security affected. When a
Default or Event of Default is waived, it is cured and ceases to exist.

Section 7.05. Limitations on Suits.

(a) A Holder may not pursue any remedy with respect to this Indenture or the Securities
(except actions for payment of overdue principal or interest or for the exchange of the Securities
pursuant to Article 4) unless:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default;

(2) the Holders of at least 25% in aggregate principal amount of the then outstanding
Securities make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee reasonable security or indemnity to the
Trustee against any loss, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of security or indemnity; and

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

(b) No Holder of a Security shall have any right under any provision of this Indenture or the
Securities to affect, disturb, or prejudice the rights of another Holder of a Security or to obtain
a preference or priority over another Holder of a Security.

Section 7.06. Rights of Holders to Receive Payment and to Exchange. Notwithstanding
any other provision of this Indenture, the right of any Holder of a Security to receive payment of
the principal or interest in respect of the Securities held by such Holder, on or after the
respective due dates expressed in the Securities and this Indenture (whether upon repurchase or
otherwise), and to exchange such Security in accordance with Article 4, and to bring suit for the
enforcement of any such payment on or after such respective due dates or for the right to exchange
in accordance with Article 4, is absolute and unconditional and shall not be impaired or affected
without the consent of the Holder.

Section 7.07. Collection Suit by Trustee. If an Event of Default described in clause
(1) or (2) of Section 7.01 occurs and is continuing, the Trustee may recover judgment in its own
name and as trustee of an express trust against the Issuer or another obligor on the Securities for
the whole amount owing with respect to the Securities and such further amount as shall be
sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 7.08. Trustee May File Proofs of Claim. The Trustee may file such proofs of
claim and other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee (including any claim for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Issuer (or any other obligor on the Securities), its creditors or its
property and shall be entitled and empowered to collect and receive any money or other property
payable or deliverable on any such claims and to distribute the same, and any receiver in any such
judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due 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 8.07, and to the extent that such payment of the reasonable compensation, expenses,
disbursements and advances in any such proceedings shall be denied for any reason, payment of the
same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other property which the Holders may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or
consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

Section 7.09. Priorities.

(a) If the Trustee collects any money pursuant to this Article 7, it shall pay out the money
in the following order:

(1) First, to the Trustee for amounts due under Section 8.07;

(2) Second, to Holders for amounts due and unpaid on the Securities for the principal
and interest, as applicable, ratably, without preference or priority of any kind, according
to such respective amounts due and payable on the Holders’ Securities; and

(3) Third, the balance, if any, to the Issuer.

(b) The Trustee may fix a record date and payment date for any payment to Holders pursuant to
this Section 7.10.

Section 7.10. Undertaking for Costs. 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, a court in its discretion may require the filing by any party litigant in the suit
of an undertaking to pay the costs of the suit, and the court in its discretion may assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
the suit, having due regard to the merits and good faith of the claims or defenses made by the
party litigant. This Section 7.11 does not apply to a suit made by the Trustee, a suit by a Holder
pursuant to Section 7.07, or a suit by Holders of more than 25% in aggregate principal amount of
the Securities then outstanding.

ARTICLE 8

TRUSTEE

Section 8.01. Obligations of Trustee.

(a) If an Event of Default of which a Responsible Officer of the Trustee shall have actual
knowledge has occurred and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture and use the same degree of care and skill in its exercise as a
prudent person would exercise or use under the circumstances in the conduct of his or her own
affairs.

(b) Except during the continuance of an Event of Default of which a Responsible Officer of the
Trustee shall have actual knowledge:

(1) the Trustee need perform only those duties as are specifically set forth in this
Indenture and no others; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture. The Trustee, however, shall examine any certificates and opinions which by any
provision hereof are specifically required to be delivered to the Trustee to determine
whether or not they conform to the requirements of this Indenture, but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated therein.

(c) The Trustee may not be relieved from liability for its own gross negligent action, its own
gross negligent failure to act, or its own willful misconduct, except that:

(1) this paragraph does not limit the effect of Section 8.01(b);

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

(3) the Trustee shall not be liable in its individual capacity with respect to any
action it takes or omits to take in good faith in accordance with a direction received by it
pursuant to Section 7.05.

(d) Subject to the provisions hereof relating to the Trustee’s duties in case of an Event of
Default, the Trustee shall be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direct of any Holders then outstanding hereunder, unless the Holders
shall have offered to the Trustee reasonable security or indemnity. The Holder of not less than a
majority in principal amount of the outstanding Securities (or of all Securities then outstanding,
as the case may be) shall have the right to direct the time, method and place of any proceeding for
any remedy available to the Trustee, or of exercising any trust or power conferred upon the
Trustee; provided that the Trustee may refuse to follow any direction which is in conflict with
applicable law or this Indenture, or which may be unduly prejudicial to the Holders not joining
therein.

(e) Every provision of this Indenture that in any way relates to the Trustee is subject to
subsections (a), (b), (c) and (d) of this Section 8.01.

(f) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

(a) Subject to Section 8.01:

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

(2) any request or direction of the Issuer or the Company mentioned herein shall be
sufficiently evidenced by an Issuer Request or Issuer Order or Company Request or Company
Order, as the case may be, and any action of the Board of Directors shall be sufficiently
evidenced by a resolution or other evidence of action of the Company.

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

(4) the Trustee may consult with counsel of its selection and the advice of such
counsel (to be confirmed in writing) or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon.

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

(6) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice,

other paper or document, but the Trustee, in its discretion, may make such further inquiry
or investigation into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Issuer and the Company, personally or by agent or
attorney.

hereunder either directly or by or through agents or attorneys and the Trustee shall not be
responsible for any misconduct or negligence on the part of any agent or attorney appointed
with due care by it hereunder.

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

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

(10) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder.

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

Section 8.03. Individual Rights of Trustee. The Trustee in its individual or any
other capacity may become the owner or pledgee of Securities and may otherwise deal with the Issuer
or an Affiliate of the Issuer with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. However, the Trustee is subject to Sections 8.10 and 8.11.

Section 8.04. Trustee’s Disclaimer. The Trustee makes no representation as to the
validity or adequacy of this Indenture or the Securities and the Trustee assumes no responsibility
for their correctness. It shall not be accountable for the Issuer’s use of the proceeds from the
Securities and it shall not be responsible for any statement in the Securities other than its
certificate of authentication.

Section 8.05. Notice of Default or Events of Default. If a Default or an Event of
Default occurs and is continuing and if it is known to the Trustee, the Trustee shall send to each
Holder of a Security notice of all uncured Defaults or Events of Default known to it within 90 days
after it occurs or, if later, within 15 days after it becomes known to the Trustee. However, the
Trustee may withhold the notice if and for so long as a committee of its Trust Officers in good
faith determines that withholding notice is in the interests of Holders of Securities, except in
the case of a Default or an Event of Default in payment of the principal of or interest on any
Security when due or in the payment of any redemption or purchase obligation, or the Issuer’s
failure to exchange Securities when obligated to exchange them. 

Section 8.06. Reports by Trustee to Holders.

(a) If a report would be required by Trust Indenture Act (“TIA”) Section 313, if this
Indenture were qualified thereunder, within 60 days after each May 15, beginning with May 15, 2008,
the Trustee shall mail to each Holder of Securities a brief report dated as of such May 15 that
complies with TIA Section 313(a). If required by TIA Section 313 were this Indenture qualified
thereunder, the Trustee also shall comply with TIA Sections 313(b)(2) and (c).

(b) A copy of each report at the time of its mailing to Holders of Securities shall be mailed
to the Issuer and, to the extent required by the TIA, filed with the SEC, and each stock exchange,
if any, on which the Securities are listed. The Issuer shall notify the Trustee whenever the
Securities become listed on any stock exchange or listed or admitted to trading on any quotation
system and any changes in the stock exchanges or quotation systems on which the Securities are
listed or admitted to trading and of any delisting thereof.

Section 8.07. Compensation and Indemnity.

(a) The Issuer shall pay to the Trustee from time to time pursuant to an agreement between the
Issuer and the Trustee such compensation (as agreed to from time to time by the Issuer and the
Trustee in writing) for its services (which compensation shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust). The Issuer shall reimburse
the Trustee upon request for all reasonable disbursements, expenses and advances incurred or made
by it. Such expenses may include the reasonable compensation, disbursements and expenses of the
Trustee’s agents and counsel.

(b) The Issuer shall indemnify the Trustee or any predecessor Trustee (which for purposes of
this Section 8.07 shall include its officers, directors, employees and agents) for, and hold it
harmless against, any and all loss, liability or expense including taxes (other than franchise
taxes and taxes based upon, measured by or determined by the income of the Trustee), incurred by
it, arising out of or in connection with the acceptance or administration of its duties under this
Indenture or any action or failure to act as authorized or within the discretion or rights or
powers conferred upon the Trustee hereunder including the reasonable costs and expenses of the
Trustee and its counsel in defending (including reasonable legal fees and expenses) itself against
any claim or liability in connection with the exercise or performance of any of its powers or
duties hereunder. The Trustee shall notify the Issuer promptly of any claim asserted against the
Trustee for which it may seek indemnity. The Issuer need not pay for any settlement effected
without its prior written consent. Anything in this Indenture to the contrary notwithstanding, in
no event shall the Trustee be liable for special, indirect or consequential loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised
of the likelihood of such loss or damage and regardless of the form of action.

(c) The Issuer need not reimburse the Trustee for any expense or indemnify it against any loss
or liability incurred by it resulting from its gross negligence, willful misconduct or bad faith.

(d) When the Trustee incurs expenses or renders services after an Event of Default specified
in clause (6) or (7) of Section 7.01(a) occurs, the expenses and the compensation for the services
are intended to constitute expenses of administration under any bankruptcy law. The provisions of
this Section shall survive the termination of this Indenture.

Section 8.08. Replacement of Trustee.

(a) The Trustee may resign by so notifying the Issuer. The Holders of a majority in aggregate
principal amount of the Securities then outstanding may remove the Trustee by so notifying the
Trustee and the Issuer and may, with the Issuer’s written consent, appoint a successor Trustee.
The Issuer may remove the Trustee at any time, so long as no Default or Event of Default has
occurred and is continuing, and appoint a Successor Trustee in accordance with this Section 8.08.

(b) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for
any reason, the Issuer shall promptly appoint a successor Trustee. If the Issuer fails to promptly
appoint a successor Trustee, the Trustee shall have the right to choose a qualified Trustee as
successor, and the Issuer shall appoint such successor as Trustee. The resignation or removal of a
Trustee shall not be effective until a successor Trustee shall have delivered the written
acceptance of its appointment as described below.

(c) If a successor Trustee does not take office within 30 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Issuer or the Holders of 10% in principal amount
of the Securities then outstanding may petition any court of competent jurisdiction for the
appointment of a successor Trustee at the expense of the Issuer.

(d) If the Trustee fails to comply with Section 8.10, any Holder may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(e) A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Issuer. Immediately after that, the retiring Trustee shall transfer all
property held by it as Trustee to the successor Trustee and be released from its obligations
(exclusive of any liabilities that the retiring Trustee may have incurred while acting as Trustee)
hereunder, the resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture.
A successor Trustee shall mail notice of its succession to each Holder.

(f) A retiring Trustee shall not be liable for the acts or omissions of any successor Trustee
after its succession.

(g) Notwithstanding replacement of the Trustee pursuant to this Section 8.08, the Issuer’s
obligations under Section 8.07 shall continue for the benefit of the retiring Trustee.

Section 8.09. Successor Trustee by Merger, Etc. If the Trustee consolidates with,
merges or converts into, or transfers all or substantially all of its corporate trust business
(including the administration of this Indenture) to, another corporation, the resulting, surviving
or transferee corporation, without any further act, shall be the successor Trustee; provided such
transferee corporation shall qualify and be eligible under Section 8.10. Such successor Trustee

holding company system, its bank holding company shall have a combined capital and surplus of at
least $50,000,000). If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of any supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section 7.09, it shall
resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 8.11. Conflicting Interests of Trustee. If the Trustee has or shall acquire a

provisions of, the Trust Indenture Act and this Indenture.

Section 8.12. Preferential Collection of Claims Against Company. If and when the
Trustee shall be or become a creditor of the Issuer (or any other obligor upon the Securities), the
Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of
the claims against the Issuer (or any such obligor).

ARTICLE 9

SATISFACTION AND DISCHARGE OF INDENTURE

Section 9.01. Discharge of Indenture.

This Indenture shall cease to be of further effect (except as to any surviving rights of
exchange, registration of transfer or exchange of Notes herein expressly provided for and except as
further provided below), and the Trustee, on demand of and at the expense of the Issuer, shall
execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a)
either: (1) all Securities theretofore authenticated and delivered (other than (i) Securities which
have been destroyed, lost or stolen and which have been replaced or paid as provided in Section
9.04 and (ii) Securities for whose payment monies have theretofore been deposited in trust and
thereafter repaid to the Issuer as provided in Section 9.04) have been delivered to the Trustee for
cancellation; or (2) all such Securities not theretofore delivered to the Trustee for cancellation
(i) have become due and payable, whether at the Final Maturity Date, the Change in Control Purchase
Date or Repurchase Date or upon exchange or otherwise, or (ii) are to be called for redemption
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 Issuer, and the Issuer, in the case of clause (1)
or (2) above, has irrevocably deposited or caused to be irrevocably deposited with the Trustee a
Paying Agent or the Exchange Agent (other than the Issuer or any of its Affiliates), as applicable,
as trust funds in trust cash and/or shares of Common Stock (as applicable under the terms of the
Indenture) in an amount sufficient to pay and discharge the entire indebtedness on such Securities
not theretofore delivered to the Trustee for cancellation, for principal and interest to the date
of such deposit (in the case of Securities which have become due and payable) or to the Maturity
Date, Redemption Date, Repurchase Date or Designated Event Repurchase Date, as the case may be;
provided, that there shall not exist, on the date of such deposit, an Event of Default; provided,
further, that such deposit 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 Issuer is a party
or to which the Issuer is bound; (b) the Issuer has paid or caused to be paid all other sums
payable hereunder by the Issuer; and (c) the Issuer has delivered to the Trustee an Officer’s
Certificate stating that all conditions precedent herein provided for relating to the satisfaction
and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Issuer to the Trustee under Section 8.07 shall survive and, if monies shall have been deposited
with the Trustee pursuant to subclause (2) of clause (a) of this Section, the provisions of
Sections 2.03, 2.05, 2.06, 2.07, 3.05, 3.06, 5.01, 5.02 and this Article 9 shall survive until the
Securities have been paid in full.

Section 9.02. Deposited Monies to Be Held in Trust by Trustee. Subject to Section
9.04, all monies deposited with the Trustee pursuant to Section 9.01 shall be held in trust for the
sole benefit of the Holders, and such monies shall be applied by the Trustee to the payment, either
directly or through any Paying Agent (including the Issuer if acting as its own Paying Agent), to
the Holders of the particular Securities for the payment or redemption of which such monies have
been deposited with the Trustee, of all sums due and to become due thereon for principal and
interest. All monies deposited with the Trustee pursuant to Section 9.01 (and held by it or any
Paying Agent) for the payment of Securities subsequently exchanged shall be returned to the Issuer
upon request. The Trustee is not responsible to anyone for interest on any deposited funds except
as agreed in writing.

Section 9.03. Paying Agent to Repay Monies Held.

Subject to the provisions of Section 9.04, the Trustee or a Paying Agent shall hold in trust,
for the benefit of the holders, all monies deposited with it pursuant to Sections 3.01, 3.03 and
11.01 and shall apply the deposited monies in accordance with this Indenture and the Securities to
the payment of the principal of and interest on the Securities.

Section 9.04. Return of Unclaimed Monies. The Trustee and each Paying Agent shall pay
to the Issuer upon request any monies held by them for the payment of principal or interest that
remains unclaimed for two years after a right to such monies have matured; provided, however, that
the Trustee or such Paying Agent, before being required to make any such payment, may, at the
expense of the Issuer, either publish in a newspaper of general circulation in The City of New
York, or cause to be mailed to each Holder entitled to such monies, notice that such monies remains
unclaimed and that after a date specified therein, which shall be at least 30 calendar days from
the date of such mailing or publication, any unclaimed balance of such monies then remaining will
be repaid to the Issuer. After payment to the Issuer, Holders entitled to monies must look to the
Issuer for payment as general creditors unless an applicable abandoned property law designates
another person, and the Trustee and each Paying Agent shall be relieved of all liability with
respect to such monies.

Section 9.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply
any monies in accordance with Section 9.02 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such application, the
Issuer’s obligations under this Indenture and the Securities shall be revived and reinstated as
though no deposit had occurred pursuant to Section 9.01 until such time as the Trustee or the
Paying Agent is permitted to apply all such monies in accordance with Section 9.02; provided that
if the Issuer makes any payment of principal of or interest on any Note following the reinstatement
of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Securities
to receive such payment from the monies held by the Trustee or Paying Agent.

ARTICLE 10

right or power conferred upon the Issuer or the Company in this Indenture;

(d) to amend or supplement any provisions of this Indenture; provided that no amendment or

(g) to evidence and provide for the acceptance of appointment by a successor Trustee and to
add to or change any of the provisions of this Indenture as is necessary to provide for or
facilitate the administration of the trusts under this Indenture by more than one Trustee;

(h) to provide for rights of Holders if any reclassification or change of Common Stock or any
consolidation, merger or sale of all or substantially all of the property or assets of the Issuer
or the Company occurs;

(i) to cure any ambiguity, defect or inconsistency in, or supplement, this Indenture provided
that such action shall not adversely affect the interests of Holders in any material respect;

(j) to modify the Indenture and the Securities to increase the Exchange Rate or reduce the
Exchange Price; provided that the increase or reduction, as the case may be, is in accordance with
the terms of the Securities or will not adversely affect the interests of the Holders; or

(k) to conform the text of this Indenture or the Securities to any provision of the
“Description of Notes” section of the Offering Circular dated April 10, 2007 pursuant to which the
Securities were offered and sold to the extent that such provision in the “Description of Notes”
section reflects a verbatim recitation of a provision of this Indenture or the Securities.

Section 10.02. With Consent of Holders. 

(a) The Issuer and the Trustee may amend or supplement this Indenture or the Securities with
the written consent of the Holders of not less than a majority in aggregate principal amount of the
Securities then outstanding and affected by such amendment or supplement (voting together as a
single class). However, subject to Section 9.04 hereof, without the written consent of each Holder
affected, an amendment, supplement or waiver may not:

(i) change the stated maturity of the principal of, or any installment of principal of,
or interest on, the Securities;

(ii) reduce the principal amount of, the rate of interest or the premium payable upon
the redemption of the Securities;

(iii) reduce the amount of principal of the Securities payable upon acceleration of the
maturity of the Securities;

(iv) change the currency of any payment of the Securities;

(v) change the place of payment on the Securities;

(vi) impair a holder’s right to sue for payment of any amount due on its Securities;

(vii) reduce the percentage of outstanding Securities necessary to modify or amend this
Indenture, to waive compliance with certain provisions thereof or certain defaults and
consequences thereunder;

(viii) modify any of the foregoing provisions or any of the provisions relating to the
waiver of certain past defaults or certain covenants, except to increase the required
percentage to effect the action or to provide that certain other provisions may not be
modified or waived without the consent of the Holders;

(ix) modify the provisions with respect to the rights of the Holders upon a Change in
Control in a manner adverse to the Holders, including the Issuer’s obligation to repurchase
the Securities following a Change in Control; or

(x) adversely affect the rights of Holders to receive payment of shares of Common Stock
or cash contained in Articles 3 and 4 hereof.

(b) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
Issuer shall promptly send to the Holders affected thereby a notice briefly describing the
amendment, supplement or waiver. Any failure of the Issuer to send such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any such amendment,
supplement or waiver.

(c) For purposes of this Indenture, Securities will be deemed outstanding if they have been
authenticated and delivered under this Indenture unless, among other things, the Securities have
matured or been cancelled, exchanged, redeemed or repurchased.

Section 10.03. Revocation and Effect of Consents. 

(a) Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is
a continuing consent by the Holder and every subsequent Holder of a Security or portion of a
Security that evidences the same debt as the consenting Holder’s Security, even if notation of the
consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the
consent as to its Security or portion of a Security if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes effective.

(b) After an amendment, supplement or waiver becomes effective, it shall bind every Holder of
a Security.

Section 10.04. Notation on or Exchange of Securities. If an amendment, supplement or
waiver changes the terms of a Security, the Trustee may require the Holder of the Security to
deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the
changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so
determines, the Issuer in exchange for the Security shall issue and the Trustee shall authenticate
a new Security that reflects the changed terms. 

Section 10.05. Trustee to Sign Amendments, Etc. The Trustee shall sign any amendment
or supplemental indenture authorized pursuant to this Article 10 if the amendment or supplemental
indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing
to sign such amendment or supplemental indenture, the Trustee shall be entitled to receive and,
subject to Section 8.01, shall be fully protected in relying upon, an Opinion of Counsel stating
that such amendment or supplemental indenture is authorized or permitted by this Indenture. The
Issuer may not sign an amendment or supplement indenture until the Board of Directors approves it.

Section 10.06. Effect of Supplemental Indentures. Upon the execution of any
supplemental indenture under this Article 9, this Indenture shall be modified in accordance
therewith, and such supplemental indenture shall form a part of this Indenture for all purposes;
and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

ARTICLE 11

REDEMPTION

Section 11.01. Redemption.

(a) The Issuer shall not have the right to redeem any Securities prior to April 15, 2012,
except as provided in this Section 11.01(a). If, at any time, the Issuer determines it is
necessary to redeem the Securities in order to preserve the Company’s status as a real estate
investment trust under the Internal Revenue Code of 1986, as amended (“REIT”), the Issuer
may redeem all of the Securities then outstanding at 100% principal amount of the Securities, plus
accrued and unpaid interest, if any, to the redemption date. In such case, the Issuer shall
provide the Trustee with an Officer’s Certificate evidencing that the Board of Directors has, in
good faith, made the determination that it is necessary to redeem the Securities in order to
preserve the Company’s status as a REIT.

(b) The Issuer shall have the right, at any time or from time to time, on or after April 15,
2012, upon not less than 30 nor more than 60 days’ prior written notice delivered to the Holders,
to redeem the Securities in whole or in part, for 100% of the principal amount of the Securities to
be redeemed plus any accrued but unpaid interest to but excluding the date of redemption date set
forth by the Issuer in such notice (the “Redemption Notice”).

(c) In the event that the Issuer shall redeem fewer than all outstanding Securities, the
Trustee will select the Securities redeemed on a pro rata basis, or by such other method the
Trustee considers fair and appropriate or is required by the Depositary for the Securities. The
Trustee shall make the selection at least 30 days but not more than 60 days before the Redemption
Date from Outstanding Securities not previously called for redemption. Securities and portions of
the principal amount thereof selected for redemption shall be in integral multiples of $1,000. The
Trustee shall notify the Issuer promptly of the Securities or portions of the principal amount
thereof to be redeemed. If the Trustee selects a portion of a Security for partial redemption and
a Holder exchanges a portion of the same Security in accordance with the provisions of Article 4
hereof before termination of the exchange right with respect to the portion of the Security so
selected, the exchanged portion of such Security shall be deemed to be from the portion selected
for redemption. Securities that have been exchanged during a selection of Securities to be
redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

(d) In the event of any redemption in part, the Issuer shall not be required to: (i) issue or
register the transfer or exchange of any Security during a period beginning at the opening of
business 15 days before any selection of Securities for redemption and ending at the close of
business on the earliest date on which the relevant notice of redemption is deemed to have been
given to all Holders of Securities to be so redeemed, or (ii) register the transfer or exchange of
any Security so selected for redemption, in whole or in part, except the unredeemed portion of any
Security being redeemed in part.

(e) A notice of redemption sent to the Holders of Securities to be redeemed in accordance with
the provisions of the two preceding paragraphs shall state:

(1) the name and address of the Paying Agent and Exchange Agent;

(2) the then current Exchange Rate;

(3) that Securities called for redemption may be exchanged at any time prior to the
close of business on the third Business Day immediately preceding the Redemption Date; and

(4) that Holders who wish to exchange Securities must comply with the procedures
relating thereto specified in Section 4.02 hereof.

(f) If the Paying Agent holds funds sufficient to pay the redemption price of the Securities
on the redemption date, then on and after such date:

(i) such Securities will cease to be outstanding;

(ii) interest on such Securities will cease to accrue; and

(iii) all rights of Holders of such Securities will terminate except the right to
receive the redemption price.

Section 11.02. Sinking Fund. No sinking fund is provided for the Securities.

covenant has been complied with.

Section 12.04. Record Date for Consent of Holders of Securities. The Issuer (or, in
the event deposits have been made pursuant to Section 9.01, the Trustee) may set a record date for
purposes of determining the identity of Holders entitled to consent to any action by consent
authorized or permitted under this Indenture, which record date shall not be more than 30 days
