the same terms and with the same CUSIP number as the Notes previously issued in an unlimited
aggregate principal amount, provided that no such additional Notes may be issued unless they will
be fungible with the Notes for U.S. federal income tax purposes.

     Section 2.02. Form of Notes. The Notes and the Trustee’s certificate of authentication to
be borne by such Notes shall be substantially in the respective forms set forth in Exhibit A, which
are incorporated in and made a part of this Indenture.

     Any Global Note may be endorsed with or have incorporated in the text thereof such legends or
recitals or changes not inconsistent with the provisions of this Indenture as may be required by
the Custodian, the Depositary, any regulatory body or required to comply with any applicable law or
regulation

11

 

thereunder or with the rules and regulations of any securities exchange or automated
quotation system upon which the Notes may be listed or traded or designated for issuance or to
conform with any usage with respect thereto, or to indicate any special limitations or restrictions
to which any particular Notes are subject.

     Any of the Notes may have such letters, numbers or other marks of identification and such
notations, legends or endorsements as the Officer executing the same may approve (execution thereof
to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any securities exchange or automated quotation
system on which the Notes may be listed or designated for issuance, or to conform to usage or to
indicate any special limitations or restrictions to which any particular Notes are subject.

     A Global Note shall represent such principal amount of the outstanding Notes as shall be
specified therein and shall provide that it shall represent the aggregate principal amount of
outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of
outstanding Notes represented thereby may from time to time be increased or reduced to reflect
redemptions,
repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global
Note to reflect the amount of any increase or decrease in the amount of outstanding Notes
represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee,
in such manner and upon instructions given by the Holder of such Notes in accordance with this
Indenture. Payment of principal (including any Redemption Price, Repurchase Price or Fundamental
Change Repurchase Price, as the case may be), accrued and unpaid interest and Additional Interest,
if any, on a Global Note shall be made to the Holder of such Note on the date of payment, unless a
record date or other means of determining Holders eligible to receive payment is provided for
herein.

     The Company shall pay the principal and interest (including Additional Interest, if any) of
any Definitive Notes at the office or agency of the Company maintained by the Company for such
purposes in the Borough of Manhattan, New York City.

     The terms and provisions contained in the form of Note attached as Exhibit A hereto shall
constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable,
the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

12

 

     Section 2.03. Date and Denomination of Notes; Payments of Interest. The Notes shall be
issuable in registered form without coupons in minimum denominations of $1,000 principal amount and
in integral multiples of $1,000 in excess thereof. Each Note shall be dated the date of its
authentication and shall bear interest from the date specified on the face of the form of Note
attached as Exhibit A hereto. Interest (including Additional Interest, if any) on the Notes shall
be computed on the basis of a 360-day year comprised of twelve 30-day months.

     The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register
at the Close of Business on any Interest Record Date with respect to any Interest Payment Date
shall be entitled to receive the interest (including Additional Interest, if any) payable on such
Interest Payment Date.

     Interest on the Notes (other than Notes that are Global Notes), including Additional Interest,
if any, will be payable (i) to Holders of the Notes having an aggregate principal amount of Notes
of $5,000,000 or less, by check mailed to the Holders of these Notes at their address in the Note
Register and (ii) to Holders having an aggregate principal amount of Notes in excess of $5,000,000,
either by check mailed to each Holder at its address in the Note Register or, upon application by a
Holder to the Registrar not later than the relevant Interest Record Date, by wire transfer in
immediately available funds to that Holder’s account within the United States, which application
shall remain in effect until that Holder notifies, in writing, the Registrar to the contrary.

     Section 2.04. Execution and Authentication. One or more Officers of the Company shall sign
the Notes on behalf of the Company by manual or facsimile signature. The Notes may be in facsimile
form.

     If an Officer of the Company whose signature is on a Note no longer holds that office at the
time the Note is authenticated, the Note shall nevertheless be valid.

     A Note shall not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent. The signature shall be conclusive evidence that the Note has been
authenticated under this Indenture.

     The Trustee shall authenticate and deliver a Global Note for original issue in an aggregate
face amount of up to $345,000,000 upon a written order of the Company signed by one Officer of the
Company.

     The Trustee may appoint an authenticating agent reasonably acceptable to the Company to
authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Trust
Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each
reference in

13

 

this Indenture to authentication by the Trustee includes authentication by such agent.
An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of
notices and demands.

     In authenticating the Notes, the Trustee shall receive, and subject to the Trust Indenture Act
will be fully protected in relying upon, an Opinion of Counsel that this Indenture and such Notes,
when authenticated and delivered by the Trustee and issued by the Company in the manner and subject
to any conditions specified in such Opinion of Counsel, will constitute valid and binding
obligations of the Company enforceable in accordance with their terms (except as the enforceability
thereof may be limited by bankruptcy, insolvency, reorganization, moratorium, or other laws
relating to or affecting creditors’ rights and by general principles of equity, and subject to
customary assumptions), and that all conditions precedent in respect of the authentication and
delivery by the Trustee of such Notes have been complied with.

     Section 2.05. Registrar and Paying Agent. The Company shall maintain, with respect to the
Notes, at the place or places pursuant to Section 2.02, an office or agency where the Notes may be
presented for registration of transfer or for exchange (the “Registrar”) and an office or agency
where the Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a
register with respect to the Notes and of their transfer and exchange (the “Note Register”). The
Company may have one or more co-registrars and one or more additional paying agents. The term
“Paying Agent” includes any additional paying agent and the term “Registrar” includes any
co-registrars. The Company hereby appoints the
Trustee as Registrar and Paying Agent for the Notes and its agency in New York City as a place
where Notes may be presented for payment or for registration of transfer or for exchange.

     The Company shall enter into an appropriate agency agreement with any Registrar or Paying
Agent not a party to this Indenture, which shall incorporate the terms of the Trust Indenture Act.
The agreement shall implement the provisions of this Indenture that relate to such agent. The
Company shall notify the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to
appropriate compensation therefor pursuant to Section 7.06. The Company or any of its domestically
organized Significant Subsidiaries may act as Paying Agent or Registrar.

     The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or
Paying Agent and to the Trustee without prior notice to the Holders of the Notes; provided,
however, that no such removal shall become effective until (a) acceptance of any appointment by a
successor as evidenced by an appropriate agreement entered into by the Company and such successor

14

 

Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (b) notification to
the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a
successor in accordance with clause (a) above. The Registrar or Paying Agent may resign at any time
upon written notice; provided, however, that the Trustee may resign as Registrar or Paying Agent
only if the Trustee also resigns as Trustee in accordance with Section 7.07.

     Section 2.06. Paying Agent to Hold Money in Trust. The Company shall require each Paying
Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust, for the
benefit of Holders of any Notes, or the Trustee, all money held by the Paying Agent for the payment
of principal of or interest on the Notes, and will notify the Trustee of any default by the Company
in making any such payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying
Agent (if other than the Company or any of its Significant Subsidiaries) shall have no further
liability for the money. If the Company or any of its Significant Subsidiaries acts as Paying
Agent, it shall segregate and hold in a separate trust fund for the benefit of Holders of any Notes
all money held by it as Paying Agent.

     Section 2.07. Holder Lists. 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 the Notes and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is
not the Registrar, the Company shall furnish to the Trustee at least ten days before each interest
payment date and at such other times as the Trustee may request in writing a list, in such form and
as of such date as the Trustee may reasonably require, of the names and addresses of Holders
of the Notes.

     Section 2.08. Transfer and Exchange. Where the Notes are presented to the Registrar or a
co-registrar with a request to register a transfer or to exchange them for an equal principal
amount of the Notes, the Registrar shall register the transfer or make the exchange if its
requirements for such transactions are met. To permit registrations of transfers and exchanges, the
Trustee shall authenticate Notes at the Registrar’s request. No service charge shall be made for
any registration of transfer or exchange (except as otherwise expressly permitted herein), but the
Company may require payment of a sum sufficient to cover any transfer tax or other similar
governmental charge required by law or permitted by this Indenture if a holder requires any shares
of Common Stock to be issued in a name other than such Holder’s name.

     Neither the Company nor the Registrar shall be required (a) to issue, register the transfer
of, or exchange Notes for the period beginning at the Open of

15

 

Business fifteen days immediately
preceding the mailing of a Notice of Redemption and ending at the Close of Business on the day of
such mailing or (b) to register the transfer of or exchange Notes selected, called or being called
for redemption as a whole or the portion being redeemed of any such Notes selected, called or being
called for redemption in part, or any Notes surrendered for repurchase or conversion, except for
any portion of the Notes not being redeemed, repurchased or converted, as the case may be.

     Section 2.09. Mutilated, Destroyed, Lost and Stolen Notes. If any mutilated Note is
surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Note and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

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

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

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

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

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

16

 

     Section 2.10. Outstanding Notes. The Notes outstanding at any time are all the Notes
authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest on a Global Note effected by the Trustee in
accordance with the provisions hereof and those described in this Section as not outstanding.

     If a Note is replaced pursuant to Section 2.09, it ceases to be outstanding until the Trustee
receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

     If the Paying Agent holds at the Stated Maturity of the Notes money sufficient to pay such
Notes payable on that date, then on and after that date such Notes cease to be outstanding and
interest on them ceases to accrue.

     A Note does not cease to be outstanding because the Company or an Affiliate of the Company
holds the Note.

     Section 2.11. Treasury Notes. In determining whether the Holders of the required principal
amount of the Notes have concurred in any request, demand, authorization, direction, notice,
consent or waiver, the Notes owned by the Company shall be disregarded, except that for the
purposes of determining whether the Trustee shall be protected in relying on any such request,
demand, authorization, direction, notice, consent or waiver only the Notes that the Trustee knows
are so owned shall be so disregarded.

     Section 2.12. Temporary Notes. Until Definitive Notes are ready for delivery, the Company
may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of Definitive Notes but may have variations that the Company considers
appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the
Trustee upon request shall authenticate Definitive Notes in exchange for temporary Notes. Until
so exchanged, temporary Notes shall have the same rights under this Indenture as the
Definitive Notes.

     Section 2.13. Cancellation. The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered
to them for registration of transfer, exchange or payment. The Trustee shall cancel all Notes
surrendered for transfer, exchange, payment, replacement or cancellation and shall dispose of such
canceled Notes in accordance with its then existing procedures therefor (subject to the record
retention requirement of the Exchange Act), and upon request shall deliver a certificate of such
disposal to the Company, unless the Company otherwise directs. The Company may not issue new Notes
to replace Notes that it has paid for or delivered to the Trustee for cancellation.

17

 

     Section 2.14. Defaulted Interest. If the Company defaults in a payment of interest on the
Notes, it shall pay the defaulted interest, plus, to the extent permitted by law, any interest
payable on the defaulted interest, to the persons who are Holders on a subsequent special record
date. The Company shall fix the record date and payment date. At least 30 days before the record
date, the Company shall mail to the Trustee and to each Holder a notice that states the record
date, the payment date and the amount of interest to be paid. The Company may pay defaulted
interest in any other lawful manner.

     Section 2.15. Global Notes.

     (a) Transfer and Exchange. Notwithstanding any provisions to the contrary contained in Section
2.08 of this Indenture and in addition thereto, any Global Note shall be exchangeable pursuant to
Section 2.08 of this Indenture for Notes registered in the names of Holders other than the
Depositary for such Note or its nominee only if (i) such Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for such Global Note or if at any time such
Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case,
the Company fails to appoint a successor Depositary within 90 days of such event or (ii) an Event
of Default with respect to the Notes represented by such Global Note shall have occurred and be
continuing. Any Global Note that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Notes registered in such names as the Depositary shall direct in writing in an
aggregate principal amount equal to the principal amount of the Global Note with like tenor and
terms.

     Except as provided in this Section 2.15(a), a Global Note may not be transferred except as a
whole by the Depositary with respect to such Global Note to a nominee of such Depositary, by a
nominee of such Depositary to such Depositary or another nominee of such Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such a successor
Depositary.

provided that any such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Notes or as contained in any Notice of Redemption or other

     Section 3.01. Notices to Trustee. The Company may not redeem the Notes prior to October 15,
2014. On or after October 15, 2014 and prior to the Stated Maturity, the Company may redeem for
cash all or part of the Notes, upon not less than 35 nor more than 60 calendar days’ notice before
the Redemption Date to the Trustee, the Paying Agent and each Holder of Notes, at 100% of the
principal amount of the Notes to be redeemed (the “Redemption Price”), plus any accrued and unpaid
interest, including any Additional Interest, to, but excluding, the Redemption Date (unless the
Redemption Date is after an Interest Record Date and on or prior to the Interest Payment Date to
which it relates, in which case interest accrued to the Interest Payment Date shall be paid to
Holders of the Notes as of such Interest Record Date and the price the Company is required to pay
the Holder surrendering the Note for redemption shall be equal to the Redemption Price and shall
not include any accrued and unpaid interest, including any Additional Interest). No Notes may be
redeemed if the principal amount of the Notes has been accelerated, and such acceleration has not
been rescinded, on or prior to the Redemption Date.

     Section 3.02. Selection of Notes To Be Redeemed. If fewer than all of the outstanding Notes
are to be redeemed and the Notes are Global Notes, the Notes shall be selected for redemption in
accordance with the Depositary procedures. If the Notes are not Global Notes, then the Trustee
shall select the Notes to be redeemed or purchased by lot, or on a pro rata basis or by another
method that complies with applicable legal and securities exchange requirements, if any, and that
the Trustee in its sole discretion shall deem to be fair and appropriate and in accordance with
methods generally used at the time of selection by fiduciaries in similar circumstances. If the
Trustee selects a portion of the Notes for partial redemption and the Holder of such Notes converts
a portion of such Notes, the converted portion shall be deemed to be from the portion selected for
redemption.
The Trustee shall make the selection at least 35 calendar days but no more than 60 calendar
days before the Redemption Date from outstanding Notes not previously called for redemption. Notes
and portions thereof that the Trustee selects shall be in principal amounts of $1,000 or integral
multiples of $1,000. Provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption. The Trustee shall promptly notify the Company of
the Notes (or portions thereof) to be redeemed.

20

 

     Section 3.03. Notice of Redemption. At least 35 calendar days but not more than 60 calendar
days before the Redemption Date, the Company shall mail a notice of redemption (the “Notice of
Redemption”) by first-class mail to each Holder of Notes to be redeemed at such Holder’s registered
address.

     The notice shall identify the Notes to be redeemed and shall state:

     (a) the Redemption Date (which must be a Business Day);

     (b) the Redemption Price;

     (c) if any Note is being redeemed in part, the portion of the principal amount of such Note to
be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in
principal amount equal to the unredeemed portion shall be issued upon cancellation of the original
Note;

     (d) the Company’s election with respect to treatment of fractional shares for conversions
during the period following the Notice of Redemption to the related Redemption Date as described
under Section 10.02(b).

     (e) the name and address of the Paying Agent;

     (f) that Notes called for redemption must be surrendered to the Paying Agent to collect the
Redemption Price;

     (g) that, unless the Company defaults in making such redemption payment or the Paying Agent is
prohibited from making such payment pursuant to the terms of this Indenture, interest on Notes (or
portion thereof) called for redemption ceases to accrue on and after the Redemption Date;

     (h) the paragraph of the Notes and/or provision of this Indenture pursuant to which the Notes
called for redemption are being redeemed;

     (i) the CUSIP or ISIN number, if any, printed on the Notes being redeemed; and

     (j) that no representation is made as to the correctness or accuracy of the CUSIP or ISIN
number, if any, listed in such notice or printed on the Notes.

     At the Company’s request, the Trustee shall give the Notice of Redemption as provided to it in
the Company’s name and at the Company’s expense. In such event, the Company shall provide the
Trustee with the information required by this Section.

21

 

     Section 3.04. Effect of Notice of Redemption. Once Notice of Redemption is mailed, Notes
called for redemption become due and payable on the Redemption Date and at the Redemption Price
stated in the notice. Upon surrender to the Paying Agent, such Notes shall be paid at the
Redemption Price stated in the notice.

     Failure to give notice or any defect in the notice to any Holder shall not affect the validity
of the notice to any other Holder.

     Section 3.05. Deposit of Redemption Price. Prior to 11:00 a.m. (New York City time) on the
Redemption Date, the Company shall deposit with the Paying Agent (or, if the Company or any
Affiliate of the Company is the Paying Agent, shall segregate and hold in trust) money sufficient
to pay the Redemption Price of, and accrued and unpaid interest (including any Additional Interest)
on, all Notes to be redeemed on that date, other than Notes or portions of Notes called for
redemption that have been delivered by the Company to the Trustee for cancellation. The Paying
Agent shall as promptly as practicable return to the Company any money deposited with it by the
Company in excess of the amounts necessary to pay the Redemption Price of, and accrued and unpaid
interest (including any Additional Interest) on, all Notes to be redeemed. If such money is then
held by the Company in trust and is not required for such purpose it shall be discharged from such
trust. The Company at any time may require a Paying Agent to pay all money held by it to the
Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this
Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

     Section 3.06. Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the
Company shall execute and the Trustee shall authenticate for the Holder (at the Company’s expense)
a new Note equal in principal amount to the unredeemed portion of the Notes surrendered.

ARTICLE 4

Covenants

     Section 4.01. Payment of Notes. The Company shall promptly make all payments in respect of
each Note on the dates and in the manner provided in such Note and in this Indenture. Such payments
shall be considered made on the date due if on such date the Trustee or the Paying Agent holds
prior to 11:00 a.m. (New York City time), in accordance with this Indenture, money sufficient to
make all payments with respect to such Notes then due and the Trustee or the
Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on
that date pursuant to the terms of this Indenture.

22

 

     Section 4.02. SEC Reports. Any documents or reports that the Company is required to file
with the SEC pursuant to Sections 13 or 15(d) of the Exchange Act must be furnished by the Company
to the Trustee within fifteen days after the same are required to be filed with the SEC (giving
effect to any grace period provided by Rule 12b-25 under the Exchange Act). Delivery of such
reports, information and documents to the Trustee is for informational purposes only and the
Trustee’s receipt of such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the Company’s compliance with
any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on the
Officers’ Certificates). The Company also shall comply with the other provisions of Trust Indenture
Act Section 314(a). The Company will be deemed to have furnished such reports referred to above to
the Trustee and the Holders if the Company has filed such reports with the SEC via the EDGAR filing
system (or any successor system)
and such reports are publicly available.

     Section 4.03. Compliance Certificate. The Company shall deliver to the Trustee within 120
days after the end of each fiscal year of the Company an Officers’ Certificate stating that in the
course of the performance by the signers of their duties as Officers of the Company they would
normally have knowledge of any Default and whether or not the signers know of any Default that
occurred during such period. If they do, the certificate shall describe the Default, its status and
what action the Company is taking or proposes to take with respect thereto. The Company also shall
comply with Trust Indenture Act Section 314(a)(4).

     Section 4.04. Further Instruments and Acts. The Company shall execute and deliver to the
Trustee such further instruments and do such further acts as may be reasonably necessary or proper
to carry out more effectively the purpose of this Indenture.

ARTICLE 5

Successor Companies

     Section 5.01. Merger and Consolidation. The Company shall not consolidate with or merge
with or into, or sell, convey, transfer or lease all or substantially all its properties and assets
to, another Person unless:

     (a) if the Company is not the resulting, surviving or transferee Person, the resulting, the
surviving or transferee Person (the “Successor Company”) is a corporation organized and existing
under the laws of the United States of America, any State thereof or the District of Columbia, and
the Successor Company shall expressly assume, by a supplemental indenture, executed and delivered
to the

23

 

Trustee, in form satisfactory to the Trustee, all the obligations of the
Company under the Notes and this Indenture; and

     (b) immediately after giving effect to such transaction no Default or Event of Default shall
have occurred and be continuing.

     The Successor Company shall succeed to, and be substituted for, and may exercise every right
and power of the Company under this Indenture.

ARTICLE 6

Defaults and Remedies

     Section 6.01. Events of Default. Each of the following shall be an “Event of Default”:

     (a) default in the payment in respect of the principal of any Note at its maturity, upon
optional redemption, upon required repurchase, upon declaration of acceleration or otherwise;

     (b) default in the payment of any interest (including Additional Interest, if any) upon any
Note when it becomes due and payable, and continuance of such default for a period of 30 days;

     (c) default in the performance, or breach, of any covenant or agreement of the Company in this
Indenture (other than a covenant or agreement a default in whose performance or whose breach is
specifically dealt with in clauses (a), (b), (d), (e) or (g) of this Section 6.01), and continuance
of such default or breach for a period of 60 days after written notice thereof has been given to
the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in
aggregate principal amount of the outstanding Notes;

     (d) the failure to comply with the obligations to convert the Notes into Common Stock in
accordance with Section 10.02 upon exercise of a Holder’s conversion right and such failure
continues for fifteen days;

     (e) the failure to timely issue a Company Notice or Fundamental Change Company Notice in
accordance with Section 11.01(b) or Section 11.02(b), as the case may be; or

     (f) (i) the Company, any Subsidiary that is a Significant Subsidiary or any group of
Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or
within the meaning of the Bankruptcy Law:

     (A) commences a voluntary case,

24

 

     (B) consents to the entry of an order for relief against it in an
involuntary case,

     (C) consents to the appointment of a custodian of it or for all or
substantially all of its property, or

     (D) makes a general assignment for the benefit of its creditors or takes
any comparable action under any foreign laws relating to insolvency; or

     (ii) a court of competent jurisdiction enters an order or decree under the Bankruptcy
Law that:

     (A) is for relief against the Company or any Subsidiary that is a
Significant Subsidiary or any group of Subsidiaries that, taken together, would
constitute a Significant Subsidiary, in an involuntary case;

     (B) appoints a custodian of the Company or any Subsidiary that is a
Significant Subsidiary or any group of Subsidiaries that, taken together, would
constitute a Significant Subsidiary or for all or substantially all of the
property of the Company or any Subsidiary that is a Significant Subsidiary or
any group of Subsidiaries that, taken together, would constitute a Significant
Subsidiary; or

     (C) orders the liquidation of the Company or any Subsidiary that is a
Significant Subsidiary or any group of Subsidiaries that, taken together, would
constitute a Significant Subsidiary;

and in each case the order or decree remains unstayed and in effect for 60 consecutive
days.

     (g) the failure by the Company to comply with its obligations under Article 5.

     Section 6.02. Acceleration. In case one or more Events of Default shall have occurred and
be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental body), then, and in
each and every such case (other than an Event of Default specified in Section 6.01(f) with respect
to the Company (and not solely with respect to a Significant Subsidiary of the Company, or a group
of Subsidiaries of the Company that in aggregate would

25

 

constitute a Significant Subsidiary of the Company), unless the principal of all of the Notes
shall have already become due and payable (or waived), either the Trustee or the Holders of at
least 25% in aggregate principal amount of the Notes then outstanding by notice in writing to the
Company (and to the Trustee if given by Noteholders), may declare 100% of the principal of and
accrued and unpaid interest and accrued and unpaid Additional Interest, if any, on all the Notes to
be due and payable immediately, and upon any such declaration the same shall become and shall
automatically be immediately due and payable, anything in this Indenture or in the Notes contained
to the contrary notwithstanding.

     If an Event of Default specified in Section 6.01(f) with respect to the Company (and not
solely with respect to a Significant Subsidiary of the Company, or a group of Subsidiaries of the
Company that in aggregate would constitute a Significant Subsidiary of the Company) occurs and is
continuing, the principal of all the Notes and accrued and unpaid interest and accrued and unpaid
Additional Interest, if any, shall be immediately due and payable.

     This provision, however, is subject to the conditions that Holders of a majority in aggregate
principal amount of the Notes then outstanding, by written notice to the Company and to the
Trustee, may waive all Defaults or Events of Default with respect to the Notes (other than a
Default or an Event of Default resulting from a nonpayment of principal or interest on the Notes,
including Additional Interest, any failure to repurchase any Notes when required or a failure to
deliver, upon conversion, shares of Common Stock due upon conversion) and rescind and annul such
declaration and its consequences, including any acceleration (other than a declaration or
consequences, as the case may be, resulting from a nonpayment of principal or interest on the
Notes, including Additional Interest, any failure to repurchase any Notes when required or a
failure to deliver, upon conversion, shares of Common Stock due upon conversion) and such Default
shall cease to exist, and any Event of Default arising therefrom (other than a Default resulting
from a nonpayment of principal or interest on the Notes, including Additional Interest, any failure
to repurchase any Notes when required or a failure to deliver, upon conversion, shares of Common
Stock due upon conversion) shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver or rescission and annulment shall extend to or shall affect any subsequent
Default or Event of Default, or shall impair any right consequent thereon. In case the Trustee
shall have initiated proceedings to enforce any right with respect to the Notes and such
proceedings shall have been discontinued or abandoned because of such rescission or annulment or
for any other reason or shall have been determined adversely to the Trustee, then and in every such
case, subject to any determination in such proceedings, the Company and the Trustee shall be
restored respectively to their former positions and rights hereunder, and all rights, remedies and
powers of the Company and the Trustee shall continue as though no such proceedings had been taken.

26

 

     Section 6.03. Collection of Indebtedness and Suits for Enforcement by Trustee. (a) The
Company covenants that (i) in case it shall default in the payment of any installment of interest
(including Additional Interest, if any) on any of the Notes, and such default shall have continued
for a period of 90 Business Days, (ii) in case it shall default in the payment of the principal of
any of the Notes when the same shall have become due and payable, whether upon maturity of the
Notes or upon declaration or otherwise, (iii) in case it shall fail to redeem any Notes pursuant to
a Notice of Redemption, (iv) in case it shall fail to repurchase any Notes when required or (v) in
case it shall fail to deliver shares of Common Stock upon conversion of the Notes, then, upon
demand of the Trustee, the Company will pay to the Trustee, for the benefit of the Holders of the
Notes, the whole amount that then shall have become due and payable on all such Notes for principal
or interest (including Additional Interest, if any), or both, as the case may be, with interest
upon the overdue principal and (to the extent that payment of such interest is enforceable under
applicable law) upon overdue installments of interest (including Additional Interest, if any) at
the rate per annum expressed in the Notes; and, in addition thereto, such further amount as shall
be sufficient to cover the costs and expenses of collection, and the amount payable to the Trustee
under Section 7.06.

     (b) If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in
its own name and as trustee of an express trust, shall be entitled and empowered to institute any
action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the Notes and collect the moneys
adjudged or decreed to be payable in the manner provided by law or equity out of the property of
the Company or other obligor upon the Notes, wherever situated.

     (c) In case of any receivership, insolvency, liquidation, bankruptcy, reorganization,
readjustment, arrangement, composition or judicial proceedings affecting the Company, or its
creditors or property, the Trustee shall have power to intervene in such proceedings and take any
action therein that may be permitted by the court and shall (except as may be otherwise provided by
law) be entitled to file such proofs of claim and other papers and documents as may be necessary or
advisable in order to have the claims of the Trustee and of the Holders of Notes allowed for the
entire amount due and payable by the Company under the Indenture at the date of institution of such
proceedings and for any additional amount that may become due and payable by the Company after such
date, and to collect and receive any moneys or other property payable or deliverable on any such
claim, and to distribute the same after the deduction of the amount payable to the Trustee under
Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of the Holders of Notes

27

 

to make such payments to the Trustee, and, in the event that the Trustee shall consent to the
making of such payments directly to such Noteholders, to pay to the Trustee any amount due it under
Section 7.06. To the extent that the payment of any such compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section Section 7.06 hereof out of the estate in any such proceeding, 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 properties that the Holders may be entitled
to receive in such proceeding, whether in liquidation or under any plan of reorganization or
arrangement or otherwise. The Trustee may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other person performing similar functions and be a member of a creditors’
or other similar committee in any such proceeding.

     (d) All rights of action and of asserting claims under this Indenture, or under any of the
terms established with respect to Notes, may be enforced by the Trustee without the possession of
any of such Notes, or the production thereof at any trial or other proceeding relative thereto, and
any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee
of an express trust, and any recovery of judgment shall, after provision for payment to the Trustee
of any amounts due under Section 7.06, be for the ratable benefit of the Holders of the Notes.

     In case of an Event of Default hereunder, the Trustee may in its discretion proceed to protect
and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as
the Trustee shall deem appropriate to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in the Indenture or in aid of the exercise of any power granted in this
Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture
or by law.

     Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment
or composition affecting the Notes or the rights of any Noteholder thereof or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such proceeding.

     Section 6.04. Application of Moneys Collected. Any moneys collected by the Trustee pursuant
to this Article and any other money or property distributable in respect of the Company’s
obligations under this Indenture after an Event of Default with respect to the Notes shall be
applied in the following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal (or premium, if any) or interest (including
Additional

28

 

Interest, if any), upon presentation of the Notes, and notation thereon of the payment, if
only partially paid, and upon surrender thereof if fully paid:

FIRST: To the payment of all obligations of the Company under Section 7.06 to compensate
and indemnify the Trustee (including any predecessor Trustee) and to pay or reimburse the
Trustee for reasonable expenses, disbursements and advances due or reasonably anticipated
to become due and the Trustee shall have a lien upon such moneys collected to satisfy such
payment obligations;

SECOND: To the payment of the amounts then due and unpaid upon the Notes for principal and
interest (including Additional Interest, if any), including, for the avoidance of doubt,
amounts payable in respect of any Conversion Obligation payable in settlement thereof, in
respect of which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind, according to the amounts due and payable on
such Notes for principal and interest (including Additional Interest, if any),
respectively; and

THIRD: To the payment of the remainder, if any, to the Company or any other Person
lawfully entitled thereto.

     Section 6.05. Limitation on Suits. No Holder of any Note shall have any right by virtue of
or by availing itself of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture, or for the
appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any
other remedy hereunder, unless (i) such Holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof, as hereinbefore provided; (ii) the
Holders of not less than 25% in aggregate principal amount of the Notes then outstanding shall have
made written request to the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder; (iii) such Holders shall have offered to the Trustee security or indemnity
reasonably satisfactory to it against any loss, liability or expense to be incurred therein or
thereby, (iv) the Trustee for sixty days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or proceeding and (v)
no direction that, in the opinion of the Trustee, is inconsistent with such written request shall
have been given to the Trustee by the Holders of a majority in principal amount of the Notes
outstanding within such sixty-day period pursuant to Section 6.08; it being understood and
intended, and being expressly covenanted by the taker and Holder of every Note with every other
taker and Holder and the Trustee that no one or more Noteholders shall have any right in any manner
whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other Noteholder, or to

29

 

obtain or seek to obtain priority over or preference to any other such Holder, or to enforce
any right under this Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all Noteholders (except as otherwise provided herein). For the protection and
enforcement of this Section 6.05, each and every Noteholder and the Trustee shall be entitled to
such relief as can be given either at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any Noteholder to receive (i) payment of the principal of (including the Redemption Price,
Repurchase Price or the Fundamental Change Repurchase Price upon repurchase pursuant to Section
3.01, Section 11.01 or Section 11.02, respectively), and accrued and unpaid interest and accrued
and unpaid Additional Interest, if any, on such Note or (ii) delivery of the Conversion Obligation
due upon conversion, in each case on or after the respective due dates expressed or provided for in
such Note or in this Indenture, or to institute suit for the enforcement of any such payment on or
after such respective dates against the Company shall not be impaired or affected without the
consent of such Noteholder.

     Anything in this Indenture or the Notes to the contrary notwithstanding, the Holder of any
Note, without the consent of either the Trustee or the Holder of any other Note, in its own behalf
and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, its rights of conversion as provided herein.

     The Trustee shall mail to all Holders any notice it receives from Holders under this Section.

     Section 6.06. Rights and Remedies Cumulative; Delay or Omission Not Waiver. Except as
otherwise provided in Section 2.09, all powers and remedies given by this Article to the Trustee or
to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of
any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the covenants and agreements
contained in this Indenture or otherwise established with respect to such Notes.

     No delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right
or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any
such right or power, or shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 6.05, every power and remedy given by this
Article or by law to the Trustee or the Noteholders may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Noteholders.

30

 

     Section 6.07. Additional Interest. Notwithstanding anything in this Indenture or in the
Notes to the contrary, if the Company so elects, the sole remedy of the Trustee or Noteholders for
an Event of Default relating to any obligation to file reports as required under Section 4.02 of
this Indenture and for any failure to comply with the requirements of Section 314(a)(1) of the
Trust Indenture Act shall, for the first 180 days after the occurrence of such an Event of Default
(which occurrence shall be no earlier than the 60th day after written notice of such Event of
Default is provided to the Company in accordance with Section 6.01(c)), consist exclusively of the
right to receive Additional Interest on the Notes at an annual rate equal to (x) 0.25% of the
outstanding principal amount of the Notes for the first 90 days an Event of Default is continuing
in such 180-day period and (y) 0.50% of the outstanding principal amount of the Notes for the
remaining 90 days an Event of Default is continuing in such 180-day period. Additional Interest
shall be payable in arrears on each Interest Payment Date following the occurrence of such Event of
Default in the same manner as regular interest on the Notes. The Company may elect to pay
Additional Interest as the sole remedy under this Section 6.07 by giving notice to the Holders, the
Trustee and Paying Agent of such election on or before the Close of Business on the 5th Business
Day after the date on which such Event of Default otherwise would occur. If the Company fails to
timely give such notice or pay Additional Interest, the Notes will be immediately subject to
acceleration in accordance with Section 6.02. On the 181st day after the occurrence of such Event
of Default (if such Event of Default is not cured or waived prior to such 181st day), the Notes
will be subject to acceleration in accordance with Section 6.02. This Section 6.07 shall not affect
the rights of the Trustee or the Noteholders in the event of the occurrence of any other Event of
Default. In the event the Company does not elect to pay Additional Interest upon an Event of
Default in accordance with this Section 6.07, the Notes will be subject to acceleration in
accordance with Section 6.02. Whenever in this Indenture there is mentioned, in any context, the
payment of interest on, or in respect of, any Note, such mention shall be deemed to include mention
of the payment of “Additional Interest” provided for in this Section 6.07 to the extent that, in
such context, Additional Interest is, was or would be payable in respect thereof pursuant to the
provisions of such sections, and express mention of the payment of Additional Interest (if
applicable) in any provision shall not be construed as excluding Additional Interest in those
provisions where such express mention is not made.

     Section 6.08. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders.
The Holders of a majority in aggregate principal amount of the Notes at the time outstanding shall
have the right to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the Trustee with respect to
Notes; provided, however, that (a) such direction shall not be in conflict with any rule of law or
with this Indenture, and (b) the Trustee may take any other action

31

 

deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may
refuse to follow any direction that conflicts with law or the Indenture or that it determines is
unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal
liability.

     Section 6.09. Notice of Defaults. The Trustee shall, within 90 days after the occurrence
and continuance of a Default of which a Trust Officer has actual knowledge, mail to all Noteholders
as the names and addresses of such Noteholders appear upon the Note Register, notice of all
Defaults known to a Trust Officer, unless such Defaults shall have been cured or waived before the
giving of such notice; and provided that, except in the case of a Default in the payment of the
principal of, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on any
of the Notes, including without limiting the generality of the foregoing any Default in the payment
of any Redemption Price, Repurchase Price or Fundamental Change Repurchase Price or a Default in
the delivery of the Conversion Obligation due upon conversion, then in any such event the Trustee
shall be protected in withholding such notice if and so long as a committee of Trust Officers of
the Trustee in good faith determine that the withholding of such notice is in the interests of the
Noteholders. The Company is required to deliver to the Trustee, within 30 days of the occurrence
thereof, written notice of any events which would constitute a Default, their status and what
action the Company is taking or proposes to take in respect thereof.

     Section 6.10. Undertaking to Pay Costs. All parties to this Indenture agree, and each
Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in
its discretion, require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that
such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and
expenses, against any party litigant in such suit, having due regard for the merits and good faith
of the claims or defenses made by such party litigant; provided that the provisions of this Section
6.10 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10%
in principal amount of the Notes at the time outstanding, or to any suit instituted by any
Noteholder for the enforcement of the payment of the principal of accrued and unpaid interest or
accrued and unpaid Additional Interest, if any, on any Note (including, but not limited to, the
Redemption Price, Repurchase Price or the Fundamental Change Repurchase Price, as the case may be,
with respect to the Notes being repurchased as provided in this Indenture) or a Default in the
delivery of the Conversion Obligation due upon conversion on or after the due date expressed or
provided for in such Note or to any suit for the enforcement of the right to convert any Note in
accordance with the provisions of Article 10.

or Opinion of Counsel.

     (f) The Trustee shall not be bound to make any investigation into the facts or matters stated

order, approval, bond, debenture, note or other paper or document.

34

 

     (g) The Trustee shall not be deemed to have notice of any Default or Event of Default with
respect to the Notes unless a Trust 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

     (h) 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

     (i) 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 security or indemnity satisfactory to the
Trustee against the costs, expenses and liabilities which might be incurred by the Trustee in
compliance with such request or direction.

     Section 7.03.
Individual Rights of Trustee. The Trustee in its individual or any other
capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same
with like rights. However, the Trustee must comply with Sections 7.09 and 7.10.

     Section 7.04.
 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company’s use of the proceeds from the Notes, and it shall not be responsible
for any statement in this Indenture, in the Notes, in the Prospectus, or in any document executed
in connection with the sale of the Notes, other than those set forth in the Trustee’s certificate
of authentication.

     Section 7.05.
 Reports by Trustee to Holder. As promptly as practicable after October 15 of
each year beginning with the October 15, 2010 for so long as Notes remain outstanding, if required
by Section 313(a) of the Trust Indenture Act, the Trustee shall mail to each Holder a brief report
dated as of such reporting date that complies with Section 313(a) of the Trust Indenture Act. The
Trustee shall also comply with Section 313(b) of the Trust Indenture Act.

     A copy of each report at the time of its mailing to Holders shall be filed with the SEC and
each stock exchange (if any) on which the Notes are listed. The Company agrees to notify promptly
the Trustee whenever the Notes become listed on any stock exchange and of any delisting thereof.

35

 

     Section 7.06.
 Compensation and Indemnity. The Company shall pay to the Trustee from time to
time such compensation for its services as the Company and the Trustee shall from time to time
agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon request for all
reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in
addition to the compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants
and experts. The Company shall indemnify the Trustee against any and all loss, liability or expense
(including reasonable attorneys’ fees) incurred by or in connection with the administration of this
trust and the performance of its duties hereunder. The Trustee shall notify the Company of any
claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided,
however, that any failure so to notify the Company shall not relieve the Company of its indemnity
obligations hereunder. The Company need not reimburse any expense or indemnify against any loss,
liability or expense incurred by an indemnified party through such party’s own willful misconduct,
negligence or bad faith.

     To secure the Company’s payment obligations pursuant to this Section, the Trustee shall have a
lien prior to the Notes on all money or property held or collected by the Trustee other than money
or property held in trust to pay the principal of and interest and any liquidated damages on
particular Notes.

     The Company’s payment obligations pursuant to this Section shall survive the satisfaction or
discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy
law or the resignation or removal of the Trustee. When the Trustee incurs expenses after the
occurrence of a Default specified in Section 6.01(f)(i) or Section 6.01(f)(ii) with respect to the
Company the expenses are intended to constitute expenses of administration under the Bankruptcy
Law.

     Section 7.07.
 Replacement of Trustee. The Trustee may resign at any time with respect to
the Notes by so notifying the Company. The Holders of a majority in principal amount of the Notes
may remove the Trustee and may appoint a successor Trustee with respect to such Notes. The Company
shall remove the Trustee if:

     (a) the Trustee fails to comply with Section 7.09;

     (b) the Trustee is adjudged bankrupt or insolvent;

     (c) a receiver or other public officer takes charge of the Trustee or its property; or

     (d) the Trustee otherwise becomes incapable of acting.

36

 

     If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal
amount of the Notes and such Holders do not reasonably promptly appoint a successor Trustee or if a
vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon 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. The successor Trustee shall mail a notice of its succession to
Holders of that Notes. The retiring Trustee shall promptly transfer all property held by it as
Trustee to the successor Trustee, subject to the lien provided for in Section 7.06.

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

     If the Trustee fails to comply with Section 7.09, any Holder of that Notes may petition any
court of competent jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

     Notwithstanding the replacement of the Trustee pursuant to this Section 7.07, the Company’s
obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

     Section 7.08.
 Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all its corporate-trust business or assets to,
another corporation or banking association, the resulting, surviving or transferee corporation
without any further act shall be the successor Trustee.

     In case at the time such successor or successors by merger, conversion or consolidation to the
Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Notes so authenticated; and if at that
time any of the Notes shall not have been authenticated, any such successor to the Trustee may
authenticate such Notes either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall
have.

37

 

     Section 7.09.
 Eligibility; Disqualification. The Trustee shall at all times satisfy the
requirements of Trust Indenture Act Section 310(a). The Trustee shall have a combined capital and
surplus of at least $100,000,000 as set forth in its most recent published annual report of
condition. The Trustee shall comply with Trust Indenture Act Section 310(b); provided, however,
that there shall be excluded from the operation of Trust Indenture Act Section 310(b)(1) any
indenture or indentures under which other securities or certificates of interest or participation
in other securities of the Company are outstanding if the requirements for such exclusion set forth
in Trust Indenture Act Section 310(b)(1) are met.

     Section 7.10.
 Preferential Collection of Claims Against the Company. The Trustee shall
comply with Trust Indenture Act Section 311(a), excluding any creditor relationship listed in Trust
Indenture Act Section 311(b). A Trustee who has resigned or has been removed shall be subject to
Trust Indenture Act Section 311(a) to the extent indicated.

     Section 8.01.
 Satisfaction and Discharge of the Indenture. When (i) the Company shall
deliver to the Registrar for cancellation all Notes theretofore authenticated (other than any Notes
that have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes
shall have been authenticated and delivered) and not theretofore canceled, or (ii) all the Notes
not theretofore canceled or delivered to the Trustee for cancellation shall have become due and
payable (whether at Stated Maturity for the payment of the principal amount thereof, on any
Redemption Date, on any Repurchase Date, on any Fundamental Change Repurchase Date or upon
conversion or otherwise) and the Company shall deposit with the Trustee, in trust, or deliver to
the Holders, as applicable, cash funds and shares of Common Stock, as applicable, sufficient to pay
all amounts due (and shares of Common Stock deliverable upon conversion, if applicable) on all of
such Notes (other than any Notes that shall have been mutilated, destroyed, lost or stolen and in
lieu of or in substitution for which other Notes shall have been authenticated and delivered) not
theretofore canceled or delivered to the Trustee for cancellation, including principal and interest
due, accompanied, except in the event the Notes are due and payable solely in cash at the Stated
Maturity of the Notes or upon an earlier Redemption Date, Repurchase Date or Fundamental Change
Repurchase Date, by a verification report as to the sufficiency of the deposited amount from an
independent certified accountant or other financial professional reasonably satisfactory to the
Trustee (which may include any of the underwriters of the initial issuance of the Notes), and if
the Company shall also pay or cause to be paid all other sums payable hereunder by

38

 

the Company, then this Indenture shall cease to be of further effect (except as to (A) rights
hereunder of Holders of the Notes to receive all amounts owing upon the Notes and the other rights,
duties and obligations of Holders of the Notes, as beneficiaries hereof with respect to the
amounts, if any, so deposited with the Trustee and (B) the rights, obligations and immunities of
the Trustee hereunder), and the Trustee, on written demand of the Company accompanied by an
Officers’ Certificate and an Opinion of Counsel as required by Section 12.04 and at the cost and
expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge
of this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or
expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee
for any services thereafter reasonably and properly rendered by the Trustee in connection with this
Indenture or the Notes.

     Section 8.02.
 Deposited Monies to Be Held in Trust by Trustee. Subject to Section 8.04, all
monies and shares of Common Stock, if applicable, deposited with the Trustee pursuant to Section
8.01 shall be held in trust for the sole benefit of the Holders of the Notes, and such monies and
shares of Common Stock, if applicable, shall be applied by the Trustee to the payment, either
directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to
the Holders of the particular Notes for the payment or redemption of which such monies and shares
of Common Stock, if applicable, have been deposited with the Trustee, of all sums due and to become
due thereon for principal and interest, if any.

     Section 8.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of
this Indenture, all monies then held by any Paying Agent of the Notes (other than the Trustee)
shall, upon written request of the Company, be repaid to it or paid to the Trustee, and thereupon
such Paying Agent shall be released from all further liability with respect to such monies.

     Section 8.04. Return of Unclaimed Monies. Subject to the requirements of applicable law,
any monies or shares of Common Stock, if applicable, deposited with or paid to the Trustee for
payment of the principal of or interest, if any, on the Notes and not applied but remaining
unclaimed by the Holders of the Notes for two years after the date upon which the principal of or
interest, if any, on such Notes, as the case may be, shall have become due and payable, shall be
repaid to the Company by the Trustee on demand and all liability of the Trustee shall thereupon
cease with respect to such monies or shares of Common Stock, if applicable; and the Holder of any
of the Notes shall thereafter look only to the Company for any payment that such Holder of the
Notes may be entitled to collect unless an applicable abandoned property law designates another
Person.

39

 

     Section 8.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any
money or shares of Common Stock, if applicable, in accordance with Section 8.02 by reason of any
order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time
as the Trustee or the Paying Agent is permitted to apply all such money or shares of Common Stock,
if applicable, in accordance with Section 8.02; provided, however, that if the Company makes any
payment of interest on or principal of any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from
the money or shares of Common Stock, if applicable, held by the Trustee or Paying Agent.

ARTICLE 9

     Section 9.01. Supplemental Indentures Without Consent of Noteholders. The Company and the
Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or

interests of any Holders;

     (b) to conform the terms of the Indenture or the Notes to the description thereof in the

     Upon the written request of the Company, the Trustee is hereby authorized to join with the
Company in the execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee shall not be obligated
to, but may in its discretion, enter into any supplemental indenture that affects the Trustee’s own
rights, duties or immunities under this Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section 9.01 may be executed
by the Company and the Trustee without the consent of the Holders of any of the Notes at the time
outstanding, notwithstanding any of the provisions of Section 9.02.

     Section 9.02. Supplemental Indentures with Consent of Noteholders. With the consent of the
Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding

to time and at any time enter into an indenture or indentures supplemental to this Indenture for
the purpose of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or any supplemental indenture or of modifying in any manner the rights

covenants, definitions or otherwise;

     (f) make any Note payable in a currency other than that stated in the Note or change any
Note’s place of payment;

     (g) change the ranking of the Notes; or

     (h) impair the right of any Holder to receive payment of principal of and interest, including
Additional Interest, if any, on such Holder’s Notes on or after the due dates therefor or to
institute suit for the enforcement of any payment on or with respect to such Holder’s Note.

     Upon the written request of the Company, and upon the filing with the Trustee of evidence of
the consent of Noteholders as aforesaid and subject only to Section 9.05, the Trustee shall join
with the Company in the execution of such supplemental indenture unless such supplemental indenture
affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental
indenture.

     It shall not be necessary for the consent of the Noteholders under this Section 9.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof.

     Section 9.03. Effect of Supplemental Indentures. Upon the execution of any supplemental
indenture pursuant to the provisions of this Article 9, this Indenture shall be and be deemed to be
modified and amended in accordance therewith and the respective rights, limitation of rights,
obligations, duties and immunities under this Indenture of the Trustee, the Company and the
Noteholders shall thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and conditions of this
Indenture for any and all purposes.

     Section 9.04. Notation on Notes. Notes authenticated and delivered after the execution of
any supplemental indenture pursuant to the provisions of this Article 9 may, at the Company’s
expense, bear a notation as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Notes so modified as to conform, in the opinion of the Board of
Directors, to any modification of this Indenture contained in any such supplemental indenture

42

 

may, at the Company’s expense, be prepared and executed by the Company, authenticated by the
Trustee or Authenticating Agent and delivered in exchange for the Notes then outstanding, upon
surrender of such Notes then outstanding.

     Section 9.05. Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee.
In addition to the documents required by Section 12.04 of this Indenture, the Trustee shall be
entitled to receive, upon request, an Officers’ Certificate and/or an Opinion of Counsel (each as
defined in Section 1.01) to the effect that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article 9 and is permitted or authorized by the Indenture
and may rely on any such Officers’ Certificate and/or Opinion of Counsel as conclusive evidence
that such supplemental indenture so complies and is so permitted or authorized.

     Section 9.06. Notice of Execution of Supplemental Indenture. After the execution by the
Company and the Trustee of any supplemental indenture with respect to the Notes pursuant to the
provisions of this Article, the Trustee shall provide a written notice, prepared by the Company,
setting forth in general terms the substance of such supplemental indenture, to the Noteholders
affected thereby as their names and addresses appear upon the Note Register. Any failure of the
Trustee to provide such notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any such supplemental indenture.

ARTICLE 10

Conversion of Notes

     Section 10.01.
 Conversion Privilege. (a) Upon compliance with the provisions of this
Article 10, a Noteholder shall have the right, at such Holder’s option, to convert all or any
portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof)
of such Note prior to the Close of Business on the second Scheduled Trading Day immediately
preceding the Stated Maturity, in each case, at an initial conversion rate (the “Conversion Rate”)
of 115.1013 shares of Common Stock (subject to adjustment as provided in Section 10.03 and Section
10.04) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 10.02,
the “Conversion Obligation”).

     Section 10.02. Conversion Procedure. (a) Subject to this Section 10.02, upon any conversion
of any Note, the Company shall deliver to converting Noteholders on the third Scheduled Trading Day
immediately following the relevant Conversion Date, in respect of the Notes being converted, a
number of shares of Common Stock equal to (i)(A) the aggregate principal amount of Notes to be
converted, divided by (B) $1,000, multiplied by (ii) the applicable Conversion Rate on the relevant
Conversion Date.

43

 

     The Company shall not issue fractional shares of Common Stock upon conversion of Notes. The
Company shall, at its election, either (i) pay cash in lieu of such fractional shares based on the
Daily VWAP of the Common Stock on the relevant Conversion Date, or (ii) increase the number of
shares of Common Stock deliverable upon conversion to the next whole share. The Company shall
inform Noteholders of its election as follows:

     (A) in respect of Notes converted on or after August 15, 2029, by notice to
all Noteholders through the Trustee on or prior to August 15, 2029;

     (B) in respect of Notes converted after the date of issuance of a Notice of
Redemption as described in Section 3.03 and prior to the related Redemption
Date, by notice to all Noteholders and the Trustee in the Notice of Redemption;
and

     (C) in all other cases, by notice to the converting Noteholder through the
Trustee no later than the second Scheduled Trading Day immediately following the
related Conversion Date.

     If the Company did not deliver a notice of its election within the applicable time period, the
Company shall be deemed to have elected to increase the number of shares of Common Stock
deliverable upon conversion as described in clause (ii) above.

     Promptly after determination of the Conversion Obligation and the amount of cash deliverable
in lieu of fractional shares of Common Stock (if any), the Company shall notify the Trustee and the
Conversion Agent of the Conversion Obligation and the amount of cash deliverable in lieu of
fractional shares of Common Stock (if any). The Trustee and the Conversion Agent shall be entitled
to rely exclusively on the notice given by the Company and shall have no responsibility for any
such determination.

     (b) Before any Holder of a Note shall be entitled to convert the same as set forth above, such
Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in
effect at that time and, if required by Section 10.02(h), pay funds equal to the amount of interest
(including Additional Interest, if any) payable on the next Interest Payment Date to which such
Holder is not entitled as set forth in Section 10.02(h) and, as set forth in Section 10.02(e), all
transfer or similar taxes, if any, and (ii) in the case of a Definitive Note, (1) complete and
manually sign and deliver an irrevocable notice to the Conversion Agent in the form on the reverse
of such Definitive Note (or a facsimile thereof) (Exhibit B hereto) (a “Notice of Conversion”) at
the office of the Conversion Agent and shall state in writing therein the principal amount of Notes
to be

44

 

converted and the name or names (with addresses) in which such Holder wishes the certificate
or certificates for any shares of Common Stock, if any, to be delivered upon settlement of the
Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or
in blank, at the office of the Conversion Agent, (3) if required by Section 10.02(h), pay funds
equal to interest (including Additional Interest, if any) payable on the next Interest Payment Date
to which such Holder is not entitled as set forth in Section 10.02(h), (4) furnish appropriate
endorsements and transfer documents, if any, and (5) pay all transfer or similar taxes, if any, as
set forth in Section 10.02(e). The Trustee (and if different, the relevant Conversion Agent) shall
notify the Company of any conversion pursuant to this Article 10 on the Conversion Date. No Notice
of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has
also delivered a Repurchase Notice or a Fundamental Change Repurchase Notice, as the case may be,
to the Company in respect of such Notes and not validly withdrawn such Repurchase Notice or
Fundamental Change Repurchase Notice in accordance with Section 11.01(e) or Section 11.02(e),
respectively.

     (c) A Note shall be deemed to have been converted immediately prior to the Close of Business
on the date (the “Conversion Date”) that the Holder has complied with all applicable requirements
set forth in clause (b) of this Section 10.02, and such Holder shall be deemed to be, on the
Conversion Date, the owner of record of a number of shares of Common Stock required to be delivered
to such Holder. The Company shall deliver such shares of Common Stock on the third Trading Day
immediately following the relevant Conversion Date; provided, that if prior to the relevant
Conversion Date, the Common Stock has been replaced by Reference Property consisting solely of
cash, pursuant to Section 10.06(b), the Company shall pay such cash on the third Trading Day
immediately following the relevant Conversion Date. If any shares of Common Stock are due to
converting Noteholders, the Company shall issue or cause to be issued, and deliver to the
Conversion Agent or to such Noteholder, or such Noteholder’s nominee or nominees, certificates or a
book-entry transfer through the Depositary for the number of full shares of Common Stock to which
such Noteholder shall be entitled in satisfaction of such Conversion Obligation.

     (d) In case any Note shall be surrendered for partial conversion, the Company shall execute
and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the
Note so surrendered, without charge to such Holder, a new Note or Notes in authorized denominations
in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

     (e) If a Holder submits a Note for conversion, the Company shall pay all stamp and other
duties, if any, that may be imposed by the United States or any political subdivision thereof or
taxing authority thereof or therein with respect to

45

 

the issuance of shares of Common Stock, if any, upon the conversion. However, the Holder shall
pay any such tax that is due because the Holder requests any shares of Common Stock to be issued in
a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificates
representing the shares of Common Stock being issued in a name other than the Holder’s name until
the Trustee receives a sum sufficient to pay any tax that will be due because the shares are to be
issued in a name other than the Holder’s name. Nothing herein shall preclude any tax withholding
required by law or regulations.

     (f) Except as provided in Section 10.04, no adjustment shall be made for dividends on any
shares of Common Stock issued upon the conversion of any Note as provided in this Article.

     (g) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the
direction of the Trustee, shall make a notation on such Global Note as to the reduction in the
principal amount represented thereby. The Company shall notify the Trustee in writing of any
conversion of Notes effected through any Conversion Agent other than the Trustee.

     (h) Upon conversion, a Noteholder shall not receive any additional cash payment or additional
shares representing accrued and unpaid interest, including Additional Interest, if any, except as
set forth in this Section 10.02(h). The Company’s settlement of the Conversion Obligations pursuant
to Section 10.02 shall be deemed to satisfy its obligation to pay the principal amount of the Note
and accrued and unpaid interest and Additional Interest, if any, on the Note to, but not including,
the Conversion Date. As a result, accrued and unpaid interest and Additional Interest, if any, to,
but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled,
extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the
Close of Business on an Interest Record Date but prior to the Open of Business on the immediately
following Interest Payment Date, Holders of such Notes as of the Close of Business on the Interest
Record Date will receive payment of the interest and Additional Interest, if any, payable on such
Notes on the corresponding Interest Payment Date notwithstanding such conversion. Notes surrendered
for conversion during the period from the Close of Business on any Interest Record Date to the Open
of Business on the corresponding Interest Payment Date must be accompanied by funds equal to the
interest and Additional Interest, if any, payable on the Notes so converted; provided, however,
that no such payment shall be required (1) if the Company has specified a Fundamental Change
Repurchase Date that is after an Interest Record Date but on or prior to the corresponding Interest
Payment Date, (2) to the extent of any Defaulted Interest, if any, existing at the time of
conversion with respect to such Note or (3) if the Company has specified a Redemption Date that is
after an Interest Record Date and on or prior the Trading Day following the corresponding Interest
Payment Date. Except as set

46

 

forth in this Section 10.02(h), no payment or adjustment will be made for accrued and unpaid
interest and Additional Interest, if any, on converted Notes.

     (i) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a stockholder of record as of the Close of Business on
the relevant Conversion Date; provided, however, if such Conversion Date occurs on any date when
the stock transfer books of the Company shall be closed, such occurrence shall not be effective to
constitute the Person or Persons entitled to receive any such shares of Common Stock due upon
conversion as the record holder or holders of such shares of Common Stock on such date, but such
occurrence shall be effective to constitute the Person or Persons entitled to receive such shares
of Common Stock as the record holder or holders thereof for all purposes at the Close of Business
on the next succeeding day on which such stock transfer books are open. Upon conversion of a Note,
such Note shall cease to be outstanding and such Person shall no longer be a Noteholder with
respect to such Note.

     Section 10.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in
Connection with Make-Whole Fundamental Changes. (a) Notwithstanding anything herein to the
contrary, the Conversion Rate applicable to each Note that is surrendered for conversion, in
accordance with this Article 10, at any time from, and including, the date on which a Make-Whole
Fundamental Change occurs (the “Effective Date”) until, and including, (x) the Close of Business on
the second Scheduled Trading Day immediately preceding the related Fundamental Change Repurchase
Date corresponding to such Make-Whole Fundamental Change, or (y) in the case of a Make-Whole
Fundamental Change that does not constitute a Fundamental Change by virtue of the parenthetical in
the definition of Make-Whole Fundamental Change, the twenty-fifth Trading Day immediately following
the Effective Date of such Make-Whole Fundamental Change, (such period, the “Make-Whole Fundamental
Change Period”), shall be increased to an amount equal to the Conversion Rate that would, but for
this Section 10.03, otherwise apply to such Note pursuant to this Article 10, plus an amount equal
to the Make-Whole Conversion Rate Adjustment.

     As used herein, “Make-Whole Conversion Rate Adjustment” means, with respect to a Make-Whole
Fundamental Change, the amount set forth in the following table that corresponds to the Effective
Date of such Make-Whole Fundamental Change and the Stock Price for such Make-Whole Fundamental
Change, all as determined by the Company:

provided, however, that:

     (i) if the actual Stock Price of such Make-Whole Fundamental Change is between two
Stock Prices listed in the table above under the row titled “Stock Price,” or if the
actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates
listed in the table above in the column immediately below the title “Effective Date,” then
the Make-Whole Conversion Rate Adjustment for such Make-Whole Fundamental Change shall be
determined by the Company by straight-line interpolation between the Make-Whole Conversion
Rate Adjustment set forth for such higher and lower Stock Prices, or for such earlier and
later Effective Dates based on a 365 day year, as applicable;

     (ii) if the actual Stock Price of such Make-Whole Fundamental Change is greater than
$60.00 per share (subject to adjustment in the same manner as the Stock Price as provided
in clause (iii) below), or if the actual Stock Price of such Make-Whole Fundamental Change
is less than $7.24 per share (subject to adjustment in the same manner as the Stock Price
as provided in clause (iii) below), then the Make-Whole Conversion Rate Adjustment shall
be equal to zero and this Section 10.03 shall not require the Company to increase the
Conversion Rate with respect to such Make-Whole Fundamental Change;

     (iii) if an event occurs that requires, pursuant to this Article 10 (other than
solely pursuant to this Section 10.03), an adjustment to the Conversion Rate, then, on the
date and at the time such adjustment is so required to be made, each price set forth in
the table immediately above under the row titled “Stock Price” shall be deemed to be
adjusted so that such Stock Price, at and after such time, shall be equal to the product
of (1) such Stock Price as in effect immediately before such adjustment to such Stock
Price and (2) a fraction whose numerator is the Conversion Rate in effect immediately
before such adjustment to the Conversion Rate and whose denominator is the Conversion Rate
to be in effect, in accordance with this Article 10, immediately after such adjustment to
the Conversion Rate;

48

 

     (iv) each Make-Whole Conversion Rate Adjustment set forth in the table above shall be
adjusted in the same manner in which, at the same time and for the same events for which,
the Conversion Rate is to be adjusted pursuant to Section 10.04; and

     (v) in no event will the total number of shares of Common Stock issuable upon
conversion of the Notes exceed 138.1215 per $1,000 principal amount of Notes, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 10.04.

     (b) As soon as practicable after the Company determines the anticipated Effective Date of any
proposed Make-Whole Fundamental Change, the Company shall provide each Noteholder, the Trustee and
the Conversion Agent written notice of, and shall issue through a public medium that is customary
for such announcements and publish on the Company’s website a press release indicating, the
anticipated Effective Date of such proposed Make-Whole Fundamental Change and shall use
commercially reasonable efforts to make such determination in time to give such notice no later
than thirty Business Days in advance of such anticipated Effective Date. Each such press release
notice, announcement and publication shall also state that in connection with such Make-Whole
Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate
applicable to Notes entitled as provided herein to such increase (along with a description of how
such increase shall be calculated and the time periods during which Notes must be surrendered in
order to be entitled to such increase). No later than five Business Days after the actual Effective
Date of each Make-Whole Fundamental Change, the Company shall provide each Noteholder, the Trustee
and the Conversion Agent written notice of, and shall issue through a public medium that is
customary for such announcements and publish on the Company’s website a press release indicating,
such Effective Date and the amount by which the Conversion Rate has been so increased.

     Nothing in this Section 10.03 shall prevent an adjustment to the Conversion Rate pursuant to
Section 10.04 in respect of a Make-Whole Fundamental Change.

     Section 10.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from
time to time by the Company as follows:

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

	 	 	 	 	 	 	 	 	 
	CR

	 	=
	 	CR0
	 	x	 	OS
	 	 	 	 	OS0

49

 

	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the applicable Conversion Rate in effect
immediately prior to the open of business on the
Record Date for such dividend or distribution, or
immediately prior to the open of business on the
effective date of such share split or share
combination, as the case may be;
	 
	 	 	 	 
	CR

	 	=
	 	the applicable Conversion Rate in effect
immediately after the open of business on the
Record Date for such dividend or distribution, or
immediately after the open of business on the
effective date of such share split or share
combination, as the case may be;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding
immediately prior to the open of business on the
Record Date for such dividend or distribution, or
immediately prior to the open of business on the
effective date of such share split or share
combination, as the case may be; and
	 
	 	 	 	 
	OS

	 	=
	 	the number of shares of Common Stock outstanding
immediately after such dividend or distribution,
or immediately after the effective date of such
share split or share combination, as the case may
be.
	 
	 	 	 	 
	 

	 	 	 	Such adjustment shall become effective immediately after the Open of Business on
the Record Date for such dividend or distribution, or the effective date for such
share split or share combination. If any dividend or distribution of the type
described in this Section 10.04(a) is declared but not so paid or made, or the
outstanding shares of Common Stock are not split or combined, as the case may be,
the Conversion Rate shall be immediately readjusted, effective as of the date the
Board of Directors determines not to pay such dividend or distribution, or split
or combine the outstanding shares of Common Stock, as the case may be, to the
Conversion Rate that would then be in effect if such dividend, distribution,
share split or share combination had not been declared or announced.

     (b) If the Company distributes to all or substantially all holders of its Common Stock any
rights, options or warrants entitling them for a period of not more than forty-five days from the
Record Date for such distribution to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the
Last Reported Sale Prices of the Common Stock for the ten

50

 

consecutive Trading Day period ending on,
and including, the Trading Day immediately preceding the declaration date for such distribution,
the Conversion Rate shall be increased based on the following formula:

	 	 	 	 	 	 	 	 	 
	CR

	 	=
	 	CR0
	 	x	 	OS0 + X
	 	 	 	 	OS0 + Y

	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the applicable Conversion Rate in effect
immediately prior to the Open of Business on the
Record Date for such distribution;
	 
	 	 	 	 
	CR

	 	=
	 	the applicable Conversion Rate in effect
immediately after the Open of Business on the
Record Date for such distribution;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of the Common Stock that are
outstanding immediately prior to the open of
business on the Record Date for such distribution;
	 
	 	 	 	 
	X

	 	=
	 	the total number of shares of the Common Stock
issuable pursuant to such rights, options or
warrants; and
	 
	 	 	 	 
	Y

	 	=
	 	the number of shares of the Common Stock equal to
the aggregate price payable to exercise such
rights, options or warrants, divided by the
average of the Last Reported Sale Prices of Common
Stock over the ten consecutive Trading Day period
ending on, and including, the Trading Day
immediately preceding the Ex-Dividend Date
relating to such distribution of such rights,
options or warrants.

Such adjustment shall be successively made whenever any such rights, options or warrants are
distributed and shall become effective immediately after the Open of Business on the Record Date
for such distribution. To the extent that shares of the Common Stock are not delivered after the
expiration of such rights, options or warrants, the Conversion Rate shall be readjusted to the
Conversion Rate that would then be in effect had the adjustments made upon the issuance of such
rights, options or warrants been made on the basis of delivery of only the number of shares of
Common Stock actually delivered. If such rights, options or warrants are not so issued, the
Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if
such Record Date for such distribution had not been fixed.

     For purposes of this Section 10.04(b), in determining whether any rights, options or warrants
entitle the holders to subscribe for or purchase shares of the Common Stock at less than the
average of the Last Reported Sale Prices of the

51

 

Common Stock for each Trading Day in the applicable
ten consecutive Trading Day period, there shall be taken into account any consideration received by
the Company for such rights, options or warrants 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. In no event shall the Conversion Rate be decreased pursuant to this Section 10.04(b).

     (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or
other of its assets or property (other than (i) dividends or distributions (including share splits)
as to which an adjustment was effected pursuant to Section 10.04(a) or Section 10.04(b) above, (ii)
dividends or distributions paid exclusively in cash, and (iii) Spin-Offs, to which the provisions
set forth below in this Section 10.04(c) shall apply) to all or substantially all holders of the
Common Stock, then, in each such case the Conversion Rate shall be increased based on the following
formula:

	 	 	 	 	 	 	 	 	 	 
	CR

	 	=
	 	CR0
	 	x	 	SP0	 
	 	 	 	 	SP0
– FMV	 

	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the applicable Conversion Rate in effect
immediately prior to the Open of Business on the
Record Date for such distribution;
	 
	 	 	 	 
	CR

	 	=
	 	the applicable Conversion Rate in effect
immediately after the Open of Business on the
Record Date for such distribution.
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale Prices of
the Common Stock over the ten consecutive Trading
Day period ending on, and including, the Trading
Day immediately preceding the Ex-Dividend Date for
such distribution; and
	 
	 	 	 	 
	FMV

	 	=
	 	the fair market value (as determined 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 the Common Stock as of the open of business on
the Ex-Dividend Date for such distribution.

Such adjustment shall become effective immediately prior to the Open of Business on the Record Date
for such distribution; provided that if “FMV” as set forth above is equal to or greater than
“SP0” as set forth above, in lieu of the foregoing adjustment, adequate provisions shall
be made so that each Noteholder shall have the right to receive, in respect of each $1,000 principal amount of the Notes held by
such Holder, at the same time and upon the same terms as holders the Common Stock, the amount and
kind of distributed property such Holder

52

 

would have received had such Holder owned a number of
shares of Common Stock equal to the Conversion Rate immediately prior to the Record Date for such
distribution. If such distribution is not so paid or made, the Conversion Rate shall again be
adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution
had not been declared. If the Board of Directors determines “FMV” for purposes of this Section
10.04(c) by reference to the actual or when issued trading market for any Notes, it must in doing
so consider the prices in such market over the same period used in computing the Last Reported Sale
Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day
immediately preceding the Ex-Dividend Date for such distribution.

     With respect to an adjustment pursuant to this Section 10.04(c) where there has been a
dividend or other distribution on the Common Stock of 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 and such dividend or distribution is listed for trading on a
securities exchange, (a
“Spin-Off”), the Conversion Rate will be increased based on the following formula:

	 	 	 	 	 	 	 	 	 	 
	CR

	 	=
	 	CR0
	 	x 	 	FMV
+
MP0	 
	 	 	 	 	MP0	 

	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the applicable Conversion Rate in effect
immediately prior to the Open of Business on the
Record Date of the Spin-Off;
	 
	 	 	 	 
	CR

	 	=
	 	the applicable Conversion Rate in effect
immediately after the Open of Business on the
Record Date of the Spin-Off;
	 
	 	 	 	 
	FMV

	 	=
	 	the average of the Last Reported Sale Prices of
the Capital Stock or similar equity interest
distributed to holders of the Common Stock
applicable to one share of the Common Stock over
the first ten consecutive Trading Day period
immediately following, and including, the
Ex-Dividend Date for the Spin-Off (such period,
the “Valuation Period”), and
	 
	 	 	 	 
	MP0

	 	=
	 	the average of the Last Reported Sale Prices of
the Common Stock over the Valuation Period.

The adjustment to the Conversion Rate under the preceding paragraph of this Section 10.04(c) shall
be made immediately after the Open of Business on the day after the last day of the Valuation Period, but shall become effective as of the Open of Business
on the Record Date for the Spin-Off. In respect of any conversion during the ten Trading Days
commencing on the Ex-Dividend Date of

53

 

any Spin-Off, references in the portion of this Section
10.04(c) related to Spin-Offs to ten Trading Days shall be deemed replaced with such lesser number
of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but
excluding, the Conversion Date for such conversion.

     Subject in all respect to Section 10.10, rights, options or warrants distributed by the
Company to all holders of its Common Stock entitling the holders thereof to subscribe for or
purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under
certain circumstances), which rights, options or warrants, until the occurrence of a specified
event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the
Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.04 (and
no adjustment to the Conversion Rate under this Section 10.04 will be required) until the
occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to
have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate
shall be made under this Section 10.04(c). If any such right, option or warrant, including any such
existing rights, options or warrants distributed prior to the date of this Indenture, are subject
to events, upon the occurrence of which such rights, options or warrants become exercisable to
purchase different securities, evidences of indebtedness or other assets, then the date of the
occurrence of any and each such event shall be deemed to be the date of distribution and
Ex-Dividend Date with respect to new rights, options or warrants with such rights (and a
termination or expiration of the existing rights, options or warrants without exercise by any of
the holders thereof). In addition, in the event of any distribution (or deemed distribution) of
rights, options or warrants, or any Trigger Event or other event (of the type described in the
preceding sentence) with respect thereto that was counted for purposes of calculating a
distribution amount for which an adjustment to the Conversion Rate under this Section 10.04 was
made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or
repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon
such final redemption or repurchase to give effect to such distribution or Trigger Event, as the
case may be, as though it were a cash distribution, equal to the per share redemption or repurchase
price received by a holder or holders of Common Stock with respect to such rights, options or
warrants (assuming such holder had retained such rights or warrants), made to all holders of Common
Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options
or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and
warrants had not been issued.

     For purposes of this Section 10.04(c), Section 10.04(a), and Section 10.04(b), any dividend or
distribution to which this Section 10.04(c) is applicable that also

54

 

includes shares of Common
Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock to which
Section 10.04(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of
the evidences of indebtedness, assets or shares of capital stock other than such shares of Common
Stock or rights, options or warrants to which Section 10.04(c) applies (and any Conversion Rate
adjustment required by this Section 10.04(c) with respect to such dividend or distribution shall
then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock
or such rights, options or warrants (and any further Conversion Rate adjustment required by Section
10.04(a) and Section 10.04(b) with respect to such dividend or distribution shall then be made),
except (A) the Ex-Dividend Date of such dividend or distribution shall be substituted as “the
Ex-Dividend Date,” “the Ex-Dividend Date relating to such distribution of such rights, options or
warrants” and “the Ex-Dividend Date for such distribution” within the meaning of Section 10.04(a)
and Section 10.04(b) and (B) any shares of Common Stock included in such dividend or distribution
shall not be deemed “outstanding immediately prior to the Ex-Dividend Date for such dividend or
distribution, or the effective date of such share split or share combination, as the case may be”
within the meaning of Section 10.04(a) or “outstanding immediately prior to the Ex-Dividend Date
for such dividend or distribution” within the meaning of Section 10.04(b).

     In no event shall the Conversion Rate be decreased pursuant to this Section 10.04(c).

     (d) If the Company makes or pays any cash dividend or distribution to all or substantially all
holders of its outstanding Common Stock, the applicable Conversion Rate shall be increased based on
the following formula:

	 	 	 	 	 	 	 	 	 	 
	CR

	 	=
	 	CR0
	 	x
	 	SP0	 
	 	 	 	 	SP0 – C	 

	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the applicable Conversion Rate in effect
immediately prior to the Open of Business on the
Record Date for such dividend or distribution;
	 
	 	 	 	 
	CR

	 	=
	 	the applicable Conversion Rate in effect
immediately after the Open of Business on the
Record Date for such dividend or distribution;
	 
	 	 	 	 
	SP0

	 	=
	 	the average of the Last Reported Sale Prices of
the Common Stock over the ten consecutive Trading
Day period ending on, and

55

 

	 	 	 	 	 
	 

	 	 	 	including, the Trading
Day immediately preceding the Ex-Dividend Date for
such dividend or distribution; and
	 
	 	 	 	 
	C

	 	=
	 	the amount in cash per share the Company pays or
distributes to holders of the Common Stock.

Such adjustment shall become effective immediately after the Open of Business on the Record Date
for such dividend or distribution; provided that if “C” as set forth above is equal to or greater
than
“SP0” as set forth above, in lieu of the foregoing adjustment, adequate provision
shall be made so that each Noteholder shall have the right to receive on the date on which the
relevant cash dividend or distribution is distributed to holders of Common Stock, for each $1,000
principal amount of Notes, the amount of cash such Holder would have received had such Holder owned
a number of shares equal to the Conversion Rate on the Record Date for such distribution. If such
dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be
the Conversion Rate that would then be in effect if such dividend or distribution had not been
declared.

     For the avoidance of doubt, for purposes of this Section 10.04(d), in the event of any
reclassification of the Common Stock, as a result of which the Notes become convertible into more
than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to
this Section 10.04(d), references in this Section to one share of Common Stock or Last Reported
Sale Prices of one share of Common Stock shall be deemed to refer to a unit or to the price of a
unit consisting of the number of shares of each class of Common Stock into which the Notes are then
convertible equal to the numbers of shares of such class issued in respect of one share of Common
Stock in such reclassification. The above provisions of this paragraph shall similarly apply to
successive reclassifications.

     In no event shall the Conversion Rate be decreased pursuant to this Section 10.04(d).

     (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or
exchange offer for the Common Stock and if the cash and value of any other consideration included
in the payment per share of the Common Stock exceeds the average of the Last Reported Sale Prices
of the Common Stock over the ten consecutive Trading-Day period commencing on, and including, the
Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to
such tender or exchange offer (the “Expiration Date”), the Conversion Rate shall be increased based on the following formula:

	 	 	 	 	 	 	 	 	 	 
	CR

	 	=
	 	CR0
	 	x
	 	AC + (SP x OS)	 
	 	 	 	 	OS0 x SP	 

56

 

	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the applicable Conversion Rate in effect
immediately prior to the Open of Business on the
Trading Day next succeeding the Expiration Date;
	 
	 	 	 	 
	CR

	 	=
	 	the applicable Conversion Rate in effect
immediately after the Open of Business on the
Trading Day next succeeding the Expiration Date;
	 
	 	 	 	 
	AC

	 	=
	 	the aggregate value of all cash and any other
consideration (as determined by the Board of
Directors) paid or payable for shares of Common
Stock purchased in such tender or exchange offer;
	 
	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding
immediately prior to the time (the “Expiration
Time”) such tender or exchange offer expires
(prior to giving effect to such tender offer or
exchange offer);
	 
	 	 	 	 
	OS

	 	=
	 	the number of shares of Common Stock outstanding
immediately after the Expiration Time (after
giving effect to such tender offer or exchange
offer); and
	 
	 	 	 	 
	SP

	 	=
	 	the average of the Last Reported Sale Prices of
Common Stock over the ten consecutive Trading-Day
period commencing on, and including, the Trading
Day next succeeding the Expiration Date.

Such adjustment under this Section 10.04(e) shall become effective at the Open of Business on the
Trading Day next succeeding the Expiration Date. In respect of any conversion during the ten
Trading Days commencing on the Trading Day next succeeding the Expiration Date, references within
this Section 10.04(e) to ten Trading Days shall be deemed replaced with such lesser number of
Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration
Date to, but excluding, the Conversion Date for such conversion. If the Company is obligated to
purchase shares pursuant to any such tender or exchange offer, but the Company is prevented from
effecting any or all or any portion of such purchases or all such purchases are rescinded, the
Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if
such tender or exchange offer had not been made or had been made only in respect of
the purchases that had been effected. In no event shall the Conversion Rate be decreased pursuant
to this Section 10.04(e).

     (f) The term “Record Date” means, with respect to any dividend, distribution or other
transaction or event in which the holders of Common Stock

57

 

(or other security) have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable
security) is exchanged for or converted into any combination of cash, securities or other property,
the date fixed for determination of stockholders entitled to receive such cash, securities or other
property (whether such date is fixed by the Board of Directors or by statute, contract or
otherwise).

     (g) In addition to those required by clauses (a), (b), (c), (d) and (e) of this Section 10.04,
and to the extent permitted by applicable law and subject to the applicable stock exchange rules,
the Company from time to time may increase the Conversion Rate by any amount for a period of at
least twenty Business Days if the Board of Directors determines that such increase would be in the
Company’s best interest. In addition, the Company may also (but is not required to) increase the
Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to
purchase Common Stock in connection with any dividend or distribution of shares (or rights to
acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall mail to the Holder of each Note at its last address appearing
on the Note Register provided for in Section 2.08 a notice of the increase at least five days prior
to the date the increased Conversion Rate takes effect, and such notice shall state the increased
Conversion Rate and the period during which it will be in effect.

     (h) The Company shall not take any action that would result in adjustment of the Conversion
Rate, pursuant to this Article 10, in such a manner as to result in the reduction of the Conversion
Price to less than the par value per share of Common Stock.

     (i) Except as provided in this Section 10.04, the Company will not be required to adjust the
Conversion Rate for any other transaction or event. Without limiting the foregoing, the applicable
Conversion Rate will not be adjusted:

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

     (ii) upon the issuance of any shares of the Common Stock or options or rights to
purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of, or assumed by, the
Company or any of the Company’s Subsidiaries;

     (iii) upon the issuance of any shares of the Common Stock pursuant to any option,
warrant, right or exercisable, exchangeable or

58

 

convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued;

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

     (v) for accrued and unpaid interest, including Additional Interest, if any; or

     (vi) for any transactions described in this Section 10.04 if Noteholders participate
(as a result of holding the Notes, and at the same time as holders of Common Stock
participate) in such transactions as if such Noteholders held the full number shares of
Common Stock equal to the product of the Conversion Rate at the time such adjustment would
be required, and the principal amount of Notes held by such Noteholder, divided by $1,000,
without having to convert their Notes.

     (j) All calculations and other determinations under this Article 10 shall be made by the
Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share.

     (k) The Company shall not be required to make an adjustment in the Conversion Rate unless the
adjustment would require a change of at least 1% in the Conversion Rate. However, the Company shall
carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried
forward adjustment, regardless of whether the aggregate adjustment is less than 1%, on the
Conversion Date for any Notes.

     (l) Except as set forth in this Article 10, the Company shall not adjust the Conversion Rate.

     (m) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate
setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the
facts requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have
received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any
adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of
which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company
shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted
Conversion Rate and the date on which each adjustment becomes effective and shall notify the Trustee and either
(i) issue a press release containing the relevant information (and make such press release
available on the Company’s website) or (ii) provide notice to the Noteholders in any manner
permitted in Section 10.09. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

59

 

     (n) If:

     (i) any event that requires an adjustment to the Conversion Rate under any of clauses
(a), (b), (c), (d) and (e) of this Section 10.04 has not resulted in an adjustment to the
Conversion Rate as of the Conversion Date; and

     (ii) the shares of Common Stock the Holder of Notes shall receive on settlement are
not entitled to participate in the distribution or transaction giving rise to such
adjustment event because, pursuant to the terms of Section 10.02(i), such shares were not
held by such Holder on the record date corresponding to such distribution or transaction
or otherwise,

then the Company will adjust the number of shares of Common Stock deliverable to reflect the
relevant distribution or transaction.

     (o) For purposes of this Section 10.04, the number of shares 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 shares of Common Stock.
The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company.

     (p) If a Noteholder is deemed to have received a distribution or dividend subject to U.S.
federal income tax as a result of an adjustment or the nonoccurrence of an adjustment of the
Conversion Rate, as a result of the distribution of cash dividends to holders of Common Stock or
otherwise, and the Company pays withholding taxes or applies backup withholding on behalf of a
Noteholder in respect of such deemed distribution or dividend, the Company may, at its option, set
off such withholding tax or backup withholding payments against subsequent payments of cash and
Common Stock on the Notes (or, in certain circumstances, against payments on Common Stock) of such
Noteholder.

     Section 10.05. Shares to Be Fully Paid. The Company shall provide, free from preemptive
rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of
Common Stock to provide for conversion of the Notes from time to time as such Notes are presented
for conversion after application of Section 10.02(a).

     Section 10.06. Effect of Reclassification, Consolidation, Merger or Sale. Upon the
occurrence of (i) any reclassification or change of the outstanding shares of Common Stock (other
than a change in par value, or from par value to no par value, or from no par value to par value,
or as a result of a split, subdivision or combination covered by Section 10.04(a)), (ii) any
consolidation, merger, combination or binding share exchange involving the Company, or (iii) any
sale,

60

 

transfer, lease or conveyance of all or substantially all of the property and assets of the
Company to any other Person, in each case as a result of which the Common Stock would be converted
into, or exchanged for stock, other securities, other property or assets (any such event a “Merger
Event”), then:

     (a) the Company or the successor or purchasing Person, as the case may be, shall execute with
the Trustee a supplemental indenture permitted under Section 9.01(c) as set forth in this
Indenture. Such supplemental indenture shall provide for adjustments that shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article 10. If, in the
case of any Merger Event, the Reference Property includes shares of stock or other securities and
assets of a corporation other than the successor or purchasing corporation, as the case may be, in
such reclassification, change, consolidation, merger, combination, binding share exchange, sale or
conveyance, then such supplemental indenture shall also be executed by such other corporation and
shall contain such additional provisions to protect the interests of the Holders of the Notes as
the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to
the extent required by the Board of Directors and practicable the provisions providing for the
repurchase rights set forth in Article 11 herein.

     In the event the Company shall execute a supplemental indenture pursuant to this Section
10.06, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating
the reasons therefor, the kind or amount of stock, other securities, other property or assets that
will comprise the Reference Property after any such Merger Event, any adjustment to be made with
respect thereto and that all conditions precedent have been complied with, and shall promptly
provide notice thereof to all Noteholders. The Company shall cause notice of the execution of such
supplemental indenture to be provided to each Noteholder, at its address appearing on the Note
Register provided for in this Indenture, within twenty days after execution thereof. Failure to
deliver such notice shall not affect the legality or validity of such supplemental indenture.

     (b) Notwithstanding the provisions of Section 10.02(a), and subject to the provisions of
Section 10.01 and Section 10.03, at and after the effective time of such Merger Event, (i) the
right to convert each $1,000 principal amount of Notes into shares of Common Stock as set forth in
Section 10.02 will be changed to a right to convert each $1,000 principal amount of such Note into
the kind and amount of shares of stock, other securities or other property or assets that a holder
of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such
transaction would have owned or been entitled to receive (the “Reference Property”) upon such
Merger Event (ii) the related Conversion Obligation shall be settled as set forth under clause (c)
below, and (iii) references herein to “Common Stock” shall be to such Reference Property to the
extent the context of such references requires.

61

 

     (c) With respect to each $1,000 principal amount of Notes surrendered for conversion after the
effective date of any such Merger Event, the Company’s Conversion Obligation shall be settled in
units of Reference Property, in accordance with Section 10.02(a) as follows:

     (i) (A) the Company shall deliver to the converting Noteholder a number of units of
Reference Property (each such unit comprised of the kind and amount of shares of stock,
other securities or other property or assets that a holder of one share of Common Stock
immediately prior to such Merger Event would have owned or been entitled to receive based
on the Weighted Average Consideration) equal to (1) the aggregate principal amount of
Notes to be converted, divided by $1,000, multiplied by (2) the then-applicable Conversion
Rate;

     (ii) The Company will deliver the cash in lieu of fractional units of Reference
Property, or increase the number of units of Reference Property to the next whole unit, as
set forth pursuant to Section 10.02(a) (provided that the amount of such cash shall be
determined as if references in such Section to “the Daily VWAP of the Common Stock” were
instead a reference to “the Daily VWAP of a unit of Reference Property” composed of the
kind and amount of shares of stock, other securities, other property or assets that a
holder of one share of Common Stock immediately prior to such Merger Event would have
owned or been entitled to receive based on the Weighted Average Consideration).

     (iii) For purposes of this Section 10.06, the “Weighted Average Consideration” means
the weighted average of the types and amounts of consideration received by the holders of
the Common Stock entitled to receive shares of stock, other securities or other property
or assets with respect to or in exchange for such Common Stock in any Merger Event (in the
event holders of the Common Stock are entitled to elect the type of consideration such
holders receive, considering only holders who affirmatively make such an election).

     (d) The above provisions of this Section shall similarly apply to successive Merger Events.

     (e) In the event that the Notes become convertible into Reference Property pursuant to this
Section 10.06, the Company shall notify the Trustee and issue a press release containing the
relevant information, which will include the Weighted Average Consideration, and make such press
release available on the Company’s website.

62

 

     (f) The Company shall not become a party to any transaction specified in the definition of a
Merger Event, unless the terms of the transaction are consistent with provisions of this Section
10.06.

     Section 10.07. Certain Covenants. (a) The Company covenants that all shares of Common Stock
issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from
all taxes, liens and charges with respect to the issue thereof.

     (b) The Company further covenants that if at any time the Common Stock shall be listed on any
national securities exchange or automated quotation system, the Company will list and keep listed,
so long as the Common Stock shall be so listed on such exchange or automated quotation system, any
Common Stock issuable upon conversion of the Notes.

     Section 10.08. Responsibility of Trustee. The Company hereby appoints the Trustee as the
initial Conversion Agent, which appointment the Trustee accepts and agrees to perform in accordance
with the terms of this Indenture. The Trustee, in its capacity as initial Conversion Agent, and any
other Conversion Agent shall not at any time be under any duty or responsibility to any Noteholder
to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may
require any adjustment (including any increase) of the Conversion 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 Conversion Agent (the “Conversion Agent”) shall not be accountable with
respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any
securities, property or cash that may at any time be issued or delivered upon the conversion of any
Note; and the Trustee and any other Conversion Agent make no representations with respect thereto.
Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to
issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or
property or cash upon the surrender of any Note for the purpose of conversion or to comply with any
of the duties, responsibilities or covenants of the Company contained in this Article. Without
limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be
under any responsibility to determine the correctness of any provisions contained in any
supplemental indenture entered into pursuant to Section 10.06 relating
either to the kind or amount of shares of stock or securities or property (including cash)
receivable by Noteholders upon the conversion of their Notes after any event referred to in such
Section 10.06 or to any adjustment to be made with respect thereto, but, subject to the provisions
of Section 7.02, may accept (without any independent investigation) as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, the Officers’
Certificate

63

 

(which the Company shall be obligated to file with the Trustee prior to the execution
of any such supplemental indenture) with respect thereto. The rights, privileges, protections,
immunities and benefits given to the Trustee, including without limitation its right to be
compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee
in each of its capacities hereunder, including its capacity as Conversion Agent.

     Section 10.09. Notice to Noteholders Prior to Certain Actions. In case:

     (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that
would require an adjustment in the Conversion Rate pursuant to Section 10.04; or

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

     (c) of any reclassification of the Common Stock of the Company (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 or merger to which 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 Company shall cause to be filed with the Trustee and to be provided to each Noteholder at its
address appearing on the Note Register provided for in Section 2.08, as promptly as possible, a
notice stating (e) the date on which a record is to be taken for the purpose of such dividend,
distribution or rights, options 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 (f) 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 10.10. Stockholder Rights Plans. To the extent that the Company has a stockholder
rights plan or other “poison pill” in effect upon conversion of

64

 

the Notes, each share of Common
Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of
rights, if any, and the certificates representing the Common Stock issued upon such conversion
shall bear such legends, if any, in each case as may be provided by the terms of any such
stockholder rights plan or poison pill, as the same may be amended from time to time. If, however,
prior to the time of conversion, the rights have separated from the shares of Common Stock in
accordance with the provisions of the applicable stockholder rights agreement so that the Holders
of the Notes would not be entitled to receive any rights in respect of Common Stock, if any,
issuable upon conversion of the Notes, the Conversion Rate will be adjusted at the time of
separation as if the Company has distributed to all holders of Common Stock, shares of Capital
Stock of the Company, evidence of indebtedness or assets as provided in Section 10.04(c), subject
to readjustment in the event of the expiration, termination or redemption of such rights.

     Section 10.11. Exchange in Lieu of Conversion. When a Noteholder surrenders its Notes for
conversion, the Company may, at its election, direct the Conversion Agent to surrender, on or prior
to the second Business Day following the relevant Conversion Date, such Notes to a financial
institution designated by the Company (the “Designated Institution”) for exchange in lieu of
conversion. In order to accept any Notes surrendered for conversion for exchange in lieu of
conversion, the Designated Institution must agree to timely deliver to the Conversion Agent for
delivery to the Noteholder, in exchange for such Notes, the shares of Common Stock that would
otherwise be due upon conversion pursuant to Section 10.02 (the “Exchange Consideration”) and in
respect of which the Company has notified converting Noteholders. By the Close of Business on the
second Business Day following the relevant Conversion Date, the Company shall notify the Holder
surrendering Notes for conversion that it has directed the Designated Institution to make an
exchange in lieu of conversion and such Designated Institution shall be required to notify the
Conversion Agent that it shall deliver, upon exchange, the applicable Exchange Consideration. The
Company shall concurrently notify the Designated Institution of the relevant deadline for delivery
of the consideration due upon conversion.

     If the Designated Institution accepts any such Notes, it shall deliver the applicable Exchange
Consideration to the Conversion Agent and the Conversion Agent shall deliver such exchange
consideration to the Holder. Any Notes exchanged by the Designated Institution will remain
outstanding. If the
Designated Institution agrees to accept any Notes for exchange but does not timely deliver the
applicable Exchange Consideration due upon conversion to the Conversion Agent, or if the Designated
Institution does not accept such Notes for exchange, the Company shall, as promptly as practical
thereafter, convert such Notes into shares of Common Stock in accordance with the provisions of
Section 10.02.

65

 

     For the avoidance of doubt, in no event will the Company’s designation of a Designated
Institution pursuant to this Section 10.11 require the Designated Institution to accept any Notes
for exchange. The Company will not pay any consideration to, or otherwise enter into any agreement
with, the Designated Institution for or with respect to such designation.

ARTICLE 11

Repurchase of Notes at Option of Noteholders

     Section 11.01. Repurchase at Option of Noteholders. (a) Each Noteholder shall have the
right to require the Company to repurchase all or a portion of such Holder’s Notes, on October 15,
2014, October 15, 2019 and October 15, 2024 (each, a “Repurchase Date”) for cash, shares of the
Company’s Common Stock or a combination thereof, at the Company’s election, at a repurchase price
equal to 100% of the principal amount thereof, together with accrued and unpaid interest (including
Additional Interest, if any) thereon to, but excluding, the Repurchase Date (the “Repurchase
Price”), unless the Repurchase Date is after an Interest Record Date and on or prior to the related
Interest Payment Date, in which case interest (including Additional Interest, if any) accrued to
the Interest Payment Date will be paid to Holders of the Notes as of the preceding Interest Record
Date and the Repurchase Price payable to the Holder surrendering the Note for repurchase pursuant
to this Section 11.01 shall be equal to the principal amount of Notes subject to repurchase and
will not include any accrued and unpaid interest (including Additional Interest, if any).
Repurchases of Notes under this Section 11.01 shall be made, at the option of the Holder thereof,
upon:

     (i) delivery to the Paying Agent by a Holder of a duly completed notice (the
“Repurchase Notice”) in the form set forth on the reverse of the Note (Exhibit C hereto)
during the period beginning at any time from the Open of Business on the Business Day that
is twenty Business Days prior the relevant Repurchase Date until the Close of Business on
the Business Day immediately preceding the Repurchase Date; and

     (ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time
after delivery of the Repurchase Notice (together with all necessary endorsements) at the
office of the Paying Agent, such delivery being a condition to receipt by the Holder of
the Repurchase Price therefor; provided that such Repurchase Price shall be so paid
pursuant to this Section 11.01 only if the Note so delivered to the Paying Agent shall
conform in all respects to the description thereof in the related Repurchase Notice.

66

 

     The Repurchase Notice shall state:

     (A) if Definitive Notes have been issued, the certificate numbers of the
Notes to be delivered for repurchase;

     (B) the portion of the principal amount of Notes to be repurchased, which
must be $1,000 or an integral multiple thereof; and

     (C) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and this Indenture;

provided, however, that if the Notes are not in certificated form, the Repurchase Notice must
comply with appropriate Depositary procedures.

     Any repurchase by the Company contemplated pursuant to the provisions of this Section 11.01
shall be consummated by the payment of the Repurchase Price pursuant to Section 11.01(f).

     Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Repurchase Notice contemplated by this Section 11.01 shall have the right to withdraw, in whole or
in part, such Repurchase Notice at any time prior to the Close of Business on the Business Day
immediately preceding the Repurchase Date in accordance with Section 11.01(e).

     The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase
Notice or written notice of withdrawal thereof.

     (b) On or before the twentieth Business Day prior to each Repurchase Date, the Company shall
provide or cause to be provided to all Holders of record of the Notes, the Paying Agent, the
Trustee and beneficial owners as required by applicable law, a notice (the “Company Notice”) of,
and issue a press release (and make such press release available on the Company’s website). Each
Company Notice shall specify:

     (i) the last date on which a Holder may exercise the repurchase right pursuant to
this Section 11.01;

     (ii) the Repurchase Price;

     (iii) the Repurchase Date;

     (iv) whether the Company elects to pay the Repurchase Price in cash, shares of Common
Stock or a combination thereof, specifying the

67

 

percentage or amounts of each; provided,
however, that if no election is made by the Company, the Company shall be deemed to have
elected to pay the Repurchase Price in cash;

     (v) the name and address of the Paying Agent;

     (vi) that Holder intending to exercise their repurchase right must exercise such
repurchase right on or prior to the Close of Business on the Business Day immediately
preceding the Repurchase Date (the “Repurchase Expiration Time”);

     (vii) that the Holder shall have the right to withdraw any Notes surrendered prior to
the Repurchase Expiration Time; and

     (viii) the procedures that Holders must follow to require the Company to repurchase
their Notes.

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 11.01.

     (c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of
the Holders if the principal amount of the Notes has been accelerated, and such acceleration has
not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration
resulting from a Default by the Company in the payment of the Repurchase Price with respect to such
Notes).

     (d) In connection with any repurchase of the Notes on a Repurchase Date, the Company will:

     (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other applicable
tender offer rules under the Exchange Act, if required under the Exchange Act,

     (ii) file a Schedule TO or any successor or similar schedule, if required under the
Exchange Act, and

     (iii) otherwise comply with all applicable federal and state securities laws in
connection with any offer by the Company to repurchase the Notes.

     Notwithstanding anything to the contrary provided in this Indenture, compliance by the Company
with Rule 13e-4, Rule 14e-1 and any other tender offer rule under the Exchange Act in accordance
with clause (i) above, to the extent inconsistent with any other provision of this Indenture, will
not, standing

68

 

alone, constitute an Event of Default solely as a result of compliance by the Company
with such rules.

     (e) A Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of
withdrawal delivered to the Paying Agent in accordance with this Section 11.01(e) at any time prior
to the Close of Business on the Business Day immediately preceding the Repurchase Date, specifying:

     (i) the principal amount of the Note with respect to which such notice of withdrawal
is being submitted,

     (ii) the certificate number, if any, of the Note in respect of which such notice of
withdrawal is being submitted, or the appropriate Depositary information if the Note in
respect of which such notice of withdrawal is being submitted is represented by a Global
Note, and

     (iii) the principal amount, if any, of such Note that remains subject to the original
Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral
multiple of $1,000;

provided, however, that if the Notes are not in certificated form, Noteholders must comply with
appropriate Depositary procedures.

     (f) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company,
or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust) on or
prior to 11:00 a.m. New York City time, on the Repurchase Date an amount of cash sufficient to
repurchase all of the Notes to be repurchased at the appropriate Repurchase Price. Subject to
receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company),
payment for Notes surrendered for repurchase (and not withdrawn prior to the Expiration Time) will
be made on the later of (i) the Repurchase Date with respect to such Note (provided the Holder has
satisfied the conditions in Section 11.01) and (ii) the time of book-entry transfer or the delivery
of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof
in the manner required by Section 11.01 by mailing checks for the amount payable to the Holders of
such Notes entitled thereto as they shall appear in the Note Register, provided, however, that
payments to the Depositary shall be made
by wire transfer of immediately available funds to the account of the Depositary or its
nominee. The Trustee shall, promptly after such payment and upon written demand by the Company,
return to the Company any funds in excess of the Repurchase Price.

     (g) If by 11:00 a.m. New York City time, on the Repurchase Date, the Trustee (or other Paying
Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions
thereof that are to be

69

 

repurchased, then (i) such Notes tendered for repurchase and not withdrawn
will cease to be outstanding and interest, including Additional Interest, if any, will cease to
accrue on such Notes on the Repurchase Date whether or not book-entry transfer of the Notes has
been made or the Notes have been delivered to the Paying Agent, and (ii) all other rights of the
Holders with respect to such Notes tendered for repurchase and not withdrawn will terminate on the
Repurchase Date (other than the right to receive the Repurchase Price, and previously accrued but
unpaid interest, including Additional Interest, if any, upon book-entry transfer or delivery of the
Notes).

     (h) Upon surrender of a Note that is to be repurchased in part pursuant to Section 11.01, the
Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an
authorized denomination equal in principal amount to the unrepurchased portion of the Note
surrendered.

     (i) If the Company elects to pay all or a part of the Repurchase Price in shares of Common
Stock, the Company shall deliver to the Paying Agent on or prior to the Repurchase Date, a number
of shares of Common Stock equal to the aggregate Repurchase Price to be paid in Common Stock
divided by the average of the Daily VWAP of the Common Stock for the twenty consecutive Trading
Days ending on the Trading Day prior to the Repurchase Date. The Company shall not issue fractional
shares of Common Stock upon repurchase of the Notes. Instead, the Company shall, at its election,
either (i) pay cash in lieu of fractional shares based on the Daily VWAP of the Common Stock on the
Trading Day prior to the Repurchase Date or (ii) increase the number of shares of Common Stock
deliverable upon repurchase of the Notes to the next whole share. If the Company’s Common Stock has
been replaced by Reference Property prior to the Repurchase Date, the number of shares of Common
Stock otherwise deliverable on such date will instead be deliverable in the amount and type of
Reference Property that a holder of that number of shares of our Common Stock would have received
in the relevant Merger Event. The Company shall not pay any portion of the Repurchase Price in
shares of Common Stock (or Reference Property, if applicable) unless the shares of Common Stock (or
Reference Property, if applicable) to be issued and delivered may be publicly resold by holders
that are not affiliates of the Company without registration under the Securities Act or if
the Company has filed an effective shelf registration statement for the sale of such shares of
Common Stock (or Reference Property, if applicable).

     Section 11.02. Repurchase at Option of Noteholders upon a Fundamental Change. (a) If there
shall occur a Fundamental Change at any time prior to the Stated Maturity, then each Noteholder
shall have the right, at such Holder’s option, to require the Company to repurchase for cash,
shares of the Company’s Common Stock or a combination thereof, at the Company’s election, all of
such Holder’s Notes, or any portion thereof that is an integral multiple of $1,000

70

 

principal
amount, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not
later than thirty-five Business Days after the date of the Fundamental Change Company Notice (as
defined below) at a repurchase price equal to 100% of the principal amount thereof, together with
accrued and unpaid interest (including Additional Interest, if any) thereon to, but excluding, the
Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the
Fundamental Change Repurchase Date is after an Interest Record Date and on or prior to the related
Interest Payment Date, in which case interest (including Additional Interest, if any) accrued to
the Interest Payment Date will be paid to Holders of the Notes as of the preceding Interest Record
Date and the Fundamental Change Repurchase Price payable to the Holder surrendering the Note for
repurchase pursuant to this Section 11.02 shall be equal to the principal amount of Notes subject
to repurchase and will not include any accrued and unpaid interest (including Additional Interest,
if any). Repurchases of Notes under this Section 11.02 shall be made, at the option of the Holder
thereof, upon:

     (i) delivery to the Paying Agent by a Holder of a duly completed notice (the
“Fundamental Change Repurchase Notice”) in the form set forth on the reverse of the Note
(Exhibit D hereto) on or prior to the Business Day immediately preceding the Fundamental
Change Repurchase Date, subject to extension to comply with applicable law; and

     (ii) delivery or book-entry transfer of the Notes to the Paying Agent on or prior to
the Business Day immediately preceding the Fundamental Change Repurchase Date (together
with all necessary endorsements) at the office of the Paying Agent, such delivery being a
condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor;
provided that such Fundamental Change Repurchase Price shall be so paid pursuant to this
Section 11.02 only if the Note so delivered to the Paying Agent shall conform in all
respects to the description thereof in the related Fundamental Change Repurchase Notice.

     The Fundamental Change Repurchase Notice shall state:

     (A) if certificated, the certificate numbers of Notes to be delivered for
repurchase;

     (B) the portion of the principal amount of Notes to be repurchased, which
must be $1,000 or an integral multiple thereof; and

     (C) that the Notes are to be repurchased by the Company pursuant to the
applicable provisions of the Notes and this Indenture;

71

 

provided, however, that if the Notes are not in certificated form, the Fundamental Change
Repurchase Notice must comply with appropriate Depositary procedures.

     Any repurchase by the Company contemplated pursuant to the provisions of this Section 11.02
shall be consummated by the payment of the Fundamental Change Repurchase Price pursuant to Section
11.02(f).

     Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Repurchase Notice contemplated by this Section 11.02 shall have the right to
withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the
Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date
in accordance with Section 11.02(e).

     The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental
Change Repurchase Notice or written notice of withdrawal thereof.

     (b) On or before the twentieth calendar day after the effective date of a Fundamental Change,
the Company shall provide or cause to be provided to all Holders of record of the Notes and the
Trustee and the Paying Agent a notice (the “Fundamental Change Company Notice”) of, and issue a
press release (and make such press release available on the Company’s website) in respect of, the
occurrence of the effective date of the Fundamental Change and of the repurchase right at the
option of the Holders arising as a result thereof. The Company shall also deliver a copy of the
Fundamental Change Company Notice to the Trustee, the Paying Agent and the Conversion Agent within
five Business Days after the effective date of the Fundamental Change. Each Fundamental Change
Company Notice shall specify:

     (i) the events causing the Fundamental Change;

     (ii) the effective date of the Fundamental Change, and if the Fundamental Change is a
Make-Whole Fundamental Change, the Effective Date of the Make-Whole Fundamental Change;

     (iii) the last date on which a Holder may exercise the repurchase right pursuant to
this Section 11.02;

     (iv) the Fundamental Change Repurchase Price;

     (v) the Fundamental Change Repurchase Date;

     (vi) whether the Company elects to pay the Fundamental Change Repurchase Price in
cash, shares of Common Stock or a

72

 

combination thereof, specifying the percentage or
amounts of each; provided, however, that if no election is made by the Company, the
Company shall be deemed to have elected to pay the Fundamental Change Repurchase Price in
cash;

     (vii) the name and address of the Paying Agent and the Conversion Agent;

     (viii) the applicable Conversion Rate, and any adjustments to the applicable
Conversion Rate resulting from the Fundamental Change;

     (ix) that the Notes with respect to which a Fundamental Change Repurchase Notice has
been delivered by a Holder may be converted only if the Holder withdraws the Fundamental
Change Repurchase Notice in accordance with the terms of this Indenture;

     (x) that the Holder must exercise the repurchase right on or prior to the Close of
Business on the Business Day immediately preceding the Fundamental Change Repurchase Date
(the “Fundamental Change Expiration Time”);

     (xi) that the Holder shall have the right to withdraw any Notes surrendered prior to
the Fundamental Change Expiration Time; and

     (xii) the procedures that Holders must follow to require the Company to repurchase
their Notes.

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 11.02.

     (c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of
the Holders upon a Fundamental Change Repurchase Date if the principal amount of the Notes has been
accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change
Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in
the payment of the Fundamental Change Repurchase Price with respect to such Notes).

     (d) In connection with any purchase of Notes on a Fundamental Change Repurchase Date, the
Company will:

     (i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other applicable
tender offer rules under the Exchange Act, if required under the Exchange Act,

73

 

     (ii) file a Schedule TO or any successor or similar schedule, if required under the
Exchange Act, and

     (iii) otherwise comply with all applicable federal and state securities laws in
connection with any offer by the Company to purchase the Notes.

     Notwithstanding anything to the contrary provided in this Indenture, compliance by the Company
with Rule 13e-4, Rule 14e-1 and any other tender offer rule under the Exchange Act in accordance
with clause (i) above, to the extent inconsistent with any other provision of this Indenture, will
not, standing alone, constitute an Event of Default solely as a result of compliance by the Company
with such rules.

     Notwithstanding the foregoing, the Company shall not be required to repurchase the Notes in
accordance with this Section 11.02 if a third party makes an offer in the manner, at the times and
otherwise in compliance with the requirements set forth in this Section 11.02 and purchases all
Notes validly tendered and not withdrawn under such purchase offer. If the third party agrees to
purchase the Notes upon a Fundamental Change but does not timely make payment of the Fundamental
Change Repurchase Price on the Fundamental Change Repurchase Date, the Company shall be required to
purchase all Notes validly tendered and not withdrawn on the Fundamental Change Repurchase Date.

     (e) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of
withdrawal delivered to the Corporate Trust Office (as defined in Section 1.01 of the Indenture) of
the Paying Agent in accordance with this Section 11.02(e) at any time prior to the Close of
Business on the Business Day immediately preceding the Fundamental Change Repurchase Date,
specifying:

     (i) the principal amount of the Note with respect to which such notice of withdrawal
is being submitted,

     (ii) the certificate number, if any, of the Note in respect of which such notice of
withdrawal is being submitted, or the appropriate Depositary information if the Note in
respect of which such notice of withdrawal is being submitted is represented by a Global
Note, and

     (iii) the principal amount, if any, of such Note that remains subject to the original
Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000
or an integral multiple of $1,000;

74

 

provided, however, that if the Notes are not in certificated form, Noteholders must comply with
appropriate Depositary procedures.

     (f) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company,
or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust) on or
prior to 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date an amount of cash
sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change
Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent
appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to
the Fundamental Change Expiration Time) will be made on the later of (i) the Fundamental Change
Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in
Section 11.02) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee
(or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by
Section 11.02 by mailing checks for the amount payable to the Holders of such Notes entitled
thereto as they shall appear in the Note Register, provided, however, that payments to the
Depositary shall be made by wire transfer of immediately available funds to the account of the
Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand
by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase
Price.

     (g) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date, the
Trustee (or other Paying Agent appointed by the Company) holds money or securities sufficient to
make payment on all the Notes or portions thereof that are to be repurchased as a result of the
corresponding Fundamental Change, then (i) such Notes tendered for repurchase and not withdrawn
will cease to be outstanding, (ii) interest, including Additional Interest, if any, will cease to
accrue on such Notes on the Fundamental Change Repurchase Date, and (iii) all other rights of the
Holders with respect to such Notes tendered for repurchase and
not withdrawn will terminate on the Fundamental Change Repurchase Date (other than the right
to receive the Fundamental Change Repurchase Price, and previously accrued but unpaid interest,
including Additional Interest, if any, upon delivery of the Notes), whether or not book-entry
transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying
Agent.

     (h) Upon surrender of a Note that is to be repurchased in part pursuant to Section 11.02, the
Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an
authorized denomination equal in principal amount to the unrepurchased portion of the Note
surrendered.

     (i) If the Company elects to pay all or a part of the Fundamental Change Repurchase Price in
shares of Common Stock, the Company shall deliver

75

 

to the Paying Agent on or prior to the
Fundamental Change Repurchase Date, a number of shares of Common Stock equal to the aggregate
Fundamental Change Repurchase Price to be paid in Common Stock divided by the average of the Daily
VWAP of the Common Stock for the twenty consecutive Trading Days ending on the Trading Day prior to
the Fundamental Change Repurchase Date. The Company shall not issue fractional shares of Common
Stock upon repurchase of the Notes. Instead, the Company shall, at its election, either (i) pay
cash in lieu of fractional shares based on the Daily VWAP of the Common Stock on the Trading Day
prior to the Fundamental Change Repurchase Date or (ii) increase the number of shares of Common
Stock deliverable upon repurchase of the Notes to the next whole share. If the Common Stock has
been replaced by Reference Property prior to the Fundamental Change Repurchase Date, the number of
shares of Common Stock otherwise deliverable on such date will instead be deliverable in the amount
and type of Reference Property that a holder of that number of shares of Common Stock would have
received in the relevant Merger Event. The Company shall not pay any portion of the Fundamental
Change Repurchase Price in shares of Common Stock (or Reference Property, if applicable) unless the
shares of Common Stock (or Reference Property, if applicable) to be issued and delivered may be
publicly resold by holders that are not affiliates of the Company without registration under the
Securities Act or if the Company has filed an effective shelf registration statement for the sale
of such shares of Common Stock (or Reference Property, if applicable).
