purposes of this definition, “control” (including, with correlative meanings, the terms
“controlling,” “controlled by” and “under common control with”) with respect to any Person, means

management and policies of such Person, whether through the ownership of Voting Securities, by

          “Agent” means any Registrar, Paying Agent or Conversion Agent.

          “Agent Member” means a member of, or a participant in, the Depositary.

          “Applicable Conversion Rate” means the Conversion Rate on any Trading Day.

          “Applicable Procedures” means, with respect to any transfer or exchange of beneficial

effect as of the date of its certification.

          “Business Day” means any day except a Saturday, Sunday or other day on which commercial banks
in New York City are authorized or obligated to close.

          “Capital Stock” means, with respect to any Person, any and all shares of stock of a
corporation, partnership interests or other equivalent interests (however designated, whether

          “Closing Price” of the Common Stock on any date means the closing sale price per share (or if
no closing sale price is reported, the average of the bid and ask prices or, if more than one in

composite transactions for the principal U.S. securities exchange on which the Common Stock is
traded or, if the Common Stock is not listed on a U.S. national or regional securities exchange, as

date of this Indenture and any shares of any class or classes of Capital Stock of the Company
resulting from any reclassification or reclassifications thereof and which have no preference in
respect of dividends or of amounts payable in the event of any voluntary or involuntary
liquidation, dissolution or winding-up of the Company and which are not subject to redemption by
the Company; provided, however, that if at any time there shall be more than one such resulting
class, the shares of each such class then so issuable on conversion of Notes shall be substantially
in the proportion which the total number of shares of such class resulting from all such
reclassifications bears to the total number of shares of all such classes resulting from all such
reclassifications.

          “Company” means the party named as such in the first paragraph of the Indenture or any
successor obligor under the Indenture and the Notes pursuant to Section 5.01.

     (b) Restricted Global Notes. All of the Notes are initially being offered and
sold to qualified institutional buyers as defined in Rule 144A (collectively, “QIBs” or
individually, each a “QIB”) in reliance on Rule 144A under the Securities Act and shall be

hereinafter provided. The aggregate principal amount of the Restricted Global Notes may

Trustee as hereinafter provided, subject in each case to compliance with the Applicable
Procedures.

     (c) Global Notes in General. Each Global Note shall represent such of the
outstanding Notes as shall be specified therein and each shall provide that it shall
represent the aggregate amount of outstanding Notes from time to time endorsed thereon and
that the aggregate amount of outstanding Notes represented thereby may from time to time be
reduced or increased, as appropriate, to reflect exchanges, purchases or conversions of such
Notes. Any adjustment of the aggregate principal amount 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 in accordance with instructions given by the Holder thereof as
required by Section 2.06 and shall be made on the records of the Trustee and the Depositary.

          Agent Members shall have no rights under this Indenture with respect to any Global Note held
on their behalf by the Depositary or under the Global Note, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any

10

 

agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (A) prevent the Company,
the Trustee or any agent of the Company or the Trustee from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or (B) impair, as between
the Depositary and its Agent Members, the operation of customary practices governing the exercise

     Section 2.02 Execution and Authentication. An Officer shall sign the Notes for the
Company by manual or facsimile signature attested by the manual or facsimile signature of the
Secretary or an Assistant Secretary of the Company. Typographic and other minor errors or defects
in any such facsimile signature shall not affect the validity or enforceability of any Note which
has been authenticated and delivered by the Trustee.

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

          A Note shall not be valid until an authorized signatory of the Trustee manually signs the
certificate of authentication on the Note. The signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

          The Trustee shall authenticate and make available for delivery Notes for original issue in the
aggregate principal amount of $1,000,000,000 (or up to $1,100,000,000 to the extent the Initial
Purchasers exercise their over-allotment option) upon receipt of a written order or orders of the
Company signed by an Officer of the Company (a “Company Order”). The Company Order shall specify
the amount of Notes to be authenticated, shall provide that all such Notes will be represented by a
Global Note and the date on which each original issue of Notes is to be authenticated. The initial
aggregate principal amount of Notes outstanding at any time may not exceed $1,000,000,000 (or
$1,100,000,000 to the extent the Initial Purchasers exercise their over-allotment option) except as
provided in Section 2.07 and except as provided in the next succeeding paragraph.

          The Company may, without the consent of any holders of Notes, reopen the Notes and issue
additional Notes hereunder with the same terms and with the same CUSIP number as the Notes
initially issued hereunder in an unlimited aggregate principal amount, which will form the same
series with the Notes initially issued hereunder so long as such additional Notes are fungible with
the Notes initially issued hereunder for U.S. federal income tax purposes.

          The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may
appoint an authenticating agent acceptable to the Company to authenticate Notes. An

11

 

authenticating
agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An authenticating agent shall
have the same rights as an Agent to deal with the Company or an Affiliate of the Company.

          The Notes shall be issuable only in registered form without coupons and only in denominations
of $1,000 principal amount and any integral multiple thereof.

     Section 2.03 Registrar, Paying Agent and Conversion Agent. The Company shall maintain

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

          The Company shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture. 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 Agent not a party to
this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or
agent for service of notices and demands in any place required by this Indenture, or fails to give
the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company
may act as Paying Agent (except for the purposes of Article 8).

          The Company hereby initially designates the Trustee as Paying Agent, Registrar, and Conversion
Agent, and the Corporate Trust Office of the Trustee as such office or agency of the Company for
each of the aforesaid purposes.

     Section 2.04 Paying Agent To Hold Money In Trust. Prior to 11:00 a.m., New York City
time, on each date on which the principal amount of or interest, if any, on any Notes is due and
payable, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal
amount or interest, if any, so becoming due. A Paying Agent shall hold in trust for the benefit of
Noteholders or the Trustee all money held by the Paying Agent for the payment of principal amount
of or interest, if any, on the Notes, and shall notify the Trustee of any default by the Company
(or any other obligor on the Notes) in making any such payment. If the Company or an Affiliate of
the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each date on
which a payment of the principal amount of or interest on any Notes is due and payable, segregate
the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent
to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any
default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the
Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other
than the Company) shall have no further liability for the money.

12

 

     Section 2.05 Noteholder 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
Noteholders. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee
on or before each semiannual 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 Noteholders.

     Section 2.06 Transfer and Exchange. Subject to compliance with any applicable
additional requirements contained in Section 2.14, when a Note is presented to a Registrar with a
request to register a transfer thereof or to exchange such Note for an equal principal amount of
Notes of other authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met; provided, however, that
every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed
or accompanied by an assignment form in the form included in Exhibit A, and in form satisfactory to
the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. To
permit registration of transfers and exchanges, upon surrender of any Note for registration of
transfer or exchange at an office or agency maintained pursuant to Section 2.03, the Company shall
execute and the Trustee shall authenticate Notes of a like aggregate principal amount at the
Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or
the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto, and provided, that this sentence shall not apply to any
exchange pursuant to Section 2.10, Section 3.04, Section 9.03(b) or Section 10.02(g) not involving
any transfer.

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

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

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

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

     Section 2.07 Replacement Notes. If any mutilated Note is surrendered to the Company,
a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company,
the applicable Registrar and the Trustee such security or indemnity as will be required by them to
save each of them harmless, then, in the absence of notice to the Company, such Registrar or the
Trustee that such Note has been acquired by a protected purchaser, the Company shall execute, and
upon its written request the Trustee shall authenticate and deliver, in exchange for any such
mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and
principal amount, 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, or is about to be purchased by the Company pursuant to Article 3, the Company in
its discretion may, instead of issuing a new Note, pay or purchase such Note, as the case may be.

          Upon the issuance of any new Notes under this Section 2.07, 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 reasonable expenses (including the reasonable fees and expenses of
the Trustee or the Registrar) in connection therewith.

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

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

     Section 2.08 Outstanding Notes. Notes outstanding at any time are all Notes
authenticated by the Trustee, except for those canceled by it, those converted pursuant to Article
10, those delivered to it for cancellation or surrendered for transfer or exchange and those
described in this Section 2.08 as not outstanding.

          If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Company
receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

          If a Paying Agent holds at 11:00 a.m., New York City time, on the Maturity Date Cash
sufficient to pay the principal amount of the Notes payable on that date, then on and after the
Maturity Date, such Notes shall cease to be outstanding and the principal amount thereof shall
cease to bear interest.

          Subject to the restrictions contained in Section 2.09, a Note does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Note.

14

 

     Section 2.09 Treasury Notes. (a) In determining whether the Holders of the required
principal amount of Notes have concurred in any notice, direction, waiver or consent, Notes owned
by the Company or any other obligor on the Notes or by any Affiliate of the Company or of such
other obligor shall be disregarded, except that, for purposes of determining whether the Trustee
shall be protected in relying on any such notice, direction, waiver or consent, only Notes which a
Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned
which have been pledged in good faith shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee’s right so to act with respect to the Notes and that the
pledgee is not the Company or any other obligor on the Notes or any Affiliate of the Company or of
such other obligor. Any Notes or shares of Common Stock issued upon the conversion of Notes that
are purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or
such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from
the registration requirements of the Securities Act in a transaction that results in such Notes or
shares of Common Stock, as the case may be, no longer being “restricted securities” (as defined
under Rule 144).

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

     Section 2.11 Cancellation. The Company at any time may deliver Notes to the Trustee
for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the
Trustee or its agent any Notes surrendered to them for transfer, exchange, payment or conversion.
The Trustee and no one else shall cancel, in accordance with its standard procedures, all Notes
surrendered for transfer, exchange, payment, conversion or cancellation and upon written request of
the Company shall deliver the canceled Notes to the Company.

     Section 2.12 CUSIP Numbers. The Company in issuing the Notes may use one or more
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in
notices of purchase as a convenience to Holders; provided, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or as
contained in any notice of a purchase and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such purchase shall not be affected by any
defect in or omission of such numbers. The Company will promptly notify the Trustee of any change
in the “CUSIP” numbers.

     Section 2.13 Book-entry Provisions For Global Notes.

     (a) Transfers of Global Notes shall be limited to transfers in whole, but not in part,
to the Depositary, its successors or their respective nominees. In addition, Certificated
Notes shall be transferred to all beneficial owners, as identified by the Depositary, in
exchange for their beneficial interests in Global Notes only if (i) the Depositary notifies
the Company that the Depositary is unwilling or unable to continue as

15

 

depositary for any
Global Note (or the Depositary ceases to be a “clearing agency” registered under Section 17A
of the Exchange Act) and a successor Depositary is not appointed by the Company within
ninety (90) days of such notice or cessation or (ii) an Event of Default has occurred and is
continuing and the Registrar has received a written request from the Depositary to issue
Certificated Notes.

     (b) In connection with the transfer of a Global Note in its entirety to beneficial
owners pursuant to Section 2.13(a), such Global Note shall be deemed to be surrendered to
the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon
written instructions from the Company authenticate and deliver, to each beneficial owner
identified by the Depositary in exchange for its beneficial interest in such Global Note, an
equal aggregate principal amount of Certificated Notes of authorized denominations.

     (c) Any Certificated Note constituting a Restricted Certificated Note delivered in
exchange for an interest in a Global Note pursuant to Section 2.13(a) shall, except as
otherwise provided by Section 2.14, bear the Restricted Note Legend.

     (d) The Holder of any Global Note may grant proxies and otherwise authorize any Person
to take any action that a Holder is entitled to take under this Indenture or the Notes.

     Section 2.14 Special Transfer Provisions.

     (a) Notwithstanding any other provisions of this Indenture, but except as provided in
Section 2.14(b), a Global Note may not be transferred except as a whole by the Depositary to
a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary.

     (b) Every Note that bears or is required under this Section 2.14(b) to bear the
Restricted Note Legend, and any Common Stock that bears or is required under this Section
2.14(b) to bear the Restricted Common Stock Legend (collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in the Restricted
Note Legend or the Restricted Common Stock Legend, as the case may be, unless such
restrictions on transfer shall be waived by written consent of the Company, and the holder
of each such Restricted Security, by such Notes holder’s acceptance thereof, agrees to be
bound by all such restrictions on transfer. As used in this Section 2.14(b), the term
“transfer” encompasses any sale, pledge, loan, transfer or other disposition whatsoever of
any Restricted Security or any interest therein.

          Until the Resale Restriction Termination Date, any certificate evidencing such Note (and all
securities issued in exchange therefor or substitution thereof), and any stock certificate
representing shares of Common Stock issued upon conversion of any Note, shall bear a Restricted
Note Legend or a Restricted Common Stock Legend, as the case may be, unless such Note or such
shares of Common Stock have been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at

16

 

the time of such
transfer) or pursuant to Rule 144 or any similar provision then in force, or such shares of Common
Stock have been issued upon conversion of Notes that have been transferred pursuant to a
registration statement that has been declared effective under the Securities Act or pursuant to
Rule 144 under the Securities Act, or unless otherwise agreed by the Company in writing, with
written notice thereof to the Trustee.

          Any Note (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms or as to conditions for
removal of the Restricted Note Legend set forth therein have been satisfied may, upon surrender of
such Note for exchange to the Registrar in accordance with the provisions of Section 2.06, be
exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not
bear the Restricted Note Legend. If the Restricted Note surrendered for exchange is represented by
a Global Note bearing the Restricted Note Legend, the principal amount of the legended Global Note
shall be reduced by the appropriate principal amount and the principal amount of a Global Note
without the Restricted Note Legend shall be increased by an equal principal amount. If a Global
Note without the Restricted Note Legend is not then outstanding, the Company shall execute and the
Trustee shall authenticate and deliver an unlegended Global Note to the Depositary.

          Any such shares of Common Stock as to which such restrictions on transfer shall have expired
in accordance with their terms or as to which the conditions for removal of the Restricted Common
Stock Legend set forth therein have been satisfied may, upon surrender of the certificates
representing such shares of Common Stock for exchange in accordance with the procedures of the
transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like
number of shares of Common Stock, which shall not bear the Restricted Common Stock Legend required
by this Section 2.14.

     (c) By its acceptance of any Note bearing the Restricted Note Legend, each Holder of
such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Note Legend and agrees that it will transfer such
Note only as provided in this Indenture and as permitted by applicable law.

     (d) The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.13 or this Section 2.14. The Company shall
have the right to inspect and make copies of all such letters, notices or other written
communications at any reasonable time during normal hours of operation of the Registrar upon
the giving of reasonable notice to the Registrar.

ARTICLE 3

PURCHASES

     Section 3.01 Repurchase At the Option of the Holder.

     (a) If there shall have occurred a Change in Control, each Holder shall have the right,
at such Holder’s option, to require the Company to purchase for Cash all or any portion of
such Holder’s Notes in integral multiples of $1,000 principal amount on a date

17

 

selected by
the Company (the “Change in Control Purchase Date”), which Change in Control Purchase Date
shall be no later than thirty-five (35) Trading Days after the occurrence of such Change in
Control, at a purchase price equal to 100% of the principal amount of the Notes to be
purchased, plus accrued and unpaid interest to, but excluding, the Change in Control
Purchase Date (the “Change in Control Purchase Price”), subject to satisfaction by or on
behalf of the Holder of the requirements set forth in Section 3.01(c); provided that if the
Change in Control Purchase Date is after a Regular Record Date and on or prior to the
Interest Payment Date to which it relates, interest accrued to the Interest Payment Date
will be paid to Holders of the Notes as of the preceding Regular Record Date.

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

     (i) any person or group, other than the Company, its Subsidiaries or any
employee benefits plan of the Company or its Subsidiaries, files a Schedule 13D or
Schedule TO (or any successor schedule, form or report) pursuant to the Exchange
Act, disclosing that such person has become the beneficial owner of shares with a
majority of the total voting power of the Company’s outstanding Voting Securities;
unless such beneficial ownership arises solely as a result of a revocable proxy
delivered in response to a proxy or consent solicitation made pursuant to the
applicable rules and regulations under the Exchange Act; or

     (ii) the Company consolidates with or merges with or into another person (other
than a Subsidiary of the Company), or sells, conveys, transfers or leases all or
substantially all of its properties and assets to any person (other than a
Subsidiary of the Company) or any person (other than a Subsidiary of the Company)
consolidates with or merges with or into the Company, and the outstanding Voting
Securities of the Company are reclassified into, converted for or converted into the right to receive any other property or security, provided
that none of these circumstances will be a Change in Control if persons that
beneficially own the Voting Securities of the Company immediately prior to the
transaction own, directly or indirectly, shares with a majority of the total voting
power of all outstanding Voting Securities of the surviving or transferee person
immediately after the transaction in substantially the same proportion as their
ownership of the Company’s Voting Securities immediately prior to the transaction.

                  For purposes of defining a Change in Control:

	 	(x)	 	the term “person” and the term “group” have the meanings given
by Section 13(d) and 14(d) of the Exchange Act or any successor provisions;
	 
	 	(y)	 	the term “group” includes any group acting for the purpose of
acquiring, holding or disposing of securities within the meaning of Rule
13d-5(b)(1) under the Exchange Act or any successor provision; and

18

 

	 	(z)	 	the term “beneficial owner” is determined in accordance with
Rules 13d-3 and 13d-5 under the Exchange Act or any successor provisions,
except that a person will be deemed to have beneficial ownership of all shares
that person has the right to acquire irrespective of whether that right is
exercisable immediately or only after the passage of time.

                  Notwithstanding the foregoing, it will not constitute a Change in Control if at least 90% of
the consideration for the Common Stock (excluding Cash payments for fractional shares and Cash
payments made in respect of dissenter’s appraisal rights and Cash payment of the Required Cash
Amount, if any) in the transaction or transactions constituting the Change in Control consists of
common stock traded on a United States national securities exchange or quoted on The Nasdaq
National Market, or which will be so traded or quoted when issued or exchanged in connection with
the Change in Control, and as a result of such transaction or transactions the Notes become
convertible solely into such common stock.

     (b) As promptly as practicable following the date the Company publicly announces the
Change in Control transaction, but in no event less than 20 Trading Days prior to the
anticipated effective date of a Change in Control, the Company shall mail a written notice
of Change in Control by first-class mail to the Trustee and to each Holder at their
addresses shown in the register of the Registrar (and to beneficial owners as required by
applicable law). The notice shall include a form of Change in Control Purchase Notice to be
completed by the Noteholder and shall state:

          (i) briefly, the events causing a Change in Control;

          (ii) the anticipated effective date of such Change in Control;

          (iii) the date by which the Change in Control Purchase Notice pursuant to this
Section 3.01 must be given;

          (iv) the Change in Control Purchase Price;

          (v) the Change in Control Purchase Date;

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

          (vii) the then-current Conversion Rate and any adjustments thereto;

          (viii) that Notes with respect to which a Change in Control Purchase Notice has
been given by the Holder may be converted pursuant to Article 10 hereof only if the
Change in Control Purchase Notice has been withdrawn in accordance with the terms of
this Indenture;

          (ix) briefly, the procedures a Holder must follow to exercise rights under this
Section 3.01;

19

 

          (x) that Notes must be surrendered to the Paying Agent to collect payment of
the Change in Control Purchase Price;

          (xi) that the Change in Control Purchase Price for any Note as to which a
Change in Control Purchase Notice has been duly given and not withdrawn, together
with any accrued interest payable with respect thereto, will be paid on or prior to
the third Trading Day following the later of the Change in Control Purchase Date and
the time of surrender of such Note;

          (xii) briefly, the conversion rights of the Notes;

          (xiii) the procedures for withdrawing a Change in Control Purchase Notice;

          (xiv) that, unless the Company defaults in making payment of such Change in
Control Purchase Price and interest due, if any, interest on Notes surrendered for
purchase will cease to accrue on and after the Change in Control Purchase Date; and

          (xv) the CUSIP number of the Notes.

     (c) A Holder may exercise its rights specified in Section 3.01(a) by delivery of a
written notice of purchase (a “Change in Control Purchase Notice”) to the Paying Agent at
any time prior to the Close of Business on the Change in Control Purchase Date, stating:

     (i) the certificate number of the Note which the Holder will deliver to be
purchased, if Certificated Notes have been issued, or notice compliant with the
relevant DTC procedures if the Notes are not certificated;

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

     (iii) that such Note shall be purchased pursuant to the terms and conditions
specified in this Article 3.

                  The delivery of such Note to the Paying Agent prior to, on or after the Change in Control
Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent shall
be a condition to the receipt by the Holder of the Change in Control Purchase Price therefor;
provided, however, that such Change in Control Purchase Price shall be so paid pursuant to this
Section 3.01 only if the Note so delivered to the Paying Agent shall conform in all respects to the
description thereof set forth in the related Change in Control Purchase Notice.

                  The Company shall purchase from the Holder thereof, pursuant to this Section 3.01, a portion
of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase
of such portion of such Note.

20

 

          Any purchase by the Company contemplated pursuant to the provisions of this Section 3.01 shall
be consummated by the delivery of the consideration to be received by the Holder (together with
accrued and unpaid interest) on or prior to the third Business Day following the later of the
Change in Control Purchase Date and the time of delivery of the Note to the Paying Agent in
accordance with this Section 3.01.

          Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Change in Control Purchase Notice contemplated by this Section 3.01(c) shall have the right to
withdraw such Change in Control Purchase Notice at any time prior to the Close of Business on the
Change in Control Purchase Date by delivery of a written notice of withdrawal to the Paying Agent
in accordance with Section 3.02.

          The Paying Agent shall promptly notify the Company of the receipt by it of any Change in
Control Purchase Notice or written withdrawal thereof.

          There shall be no purchase of any Notes pursuant to this Section 3.01 if there has occurred
(prior to, on or after, as the case may be, the giving, by the Holders of such Notes, of the
required Change in Control Purchase Notice) and is continuing an Event of Default (other than a
default in the payment of the Change in Control Purchase Price). The Paying Agent will promptly
return to the respective Holders thereof any Notes (x) with respect to which a Change in Control
Purchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the
continuance of an Event of Default (other than a default in the payment of the Change in Control
Purchase Price) in which case, upon such return, the Change in Control Purchase Notice with respect
thereto shall be deemed to have been withdrawn.

     Section 3.02 Effect of Change in Control Purchase Notice.

     (a) Upon receipt by the Paying Agent of the Change in Control Purchase Notice specified
in Section 3.01(c), the Holder of the Note in respect of which such Change in Control Purchase Notice was given shall (unless such Change in Control Purchase Notice
is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive
solely the Change in Control Purchase Price and any accrued and unpaid interest, with
respect to such Note. Such Change in Control Purchase Price and interest shall be paid to
such Holder, subject to receipt of funds by the Paying Agent, on or prior to the third
Business Day following the later of (x) the Change in Control Purchase Date, with respect to
such Note (provided the conditions in Section 3.01(c) have been satisfied) and (y) the time
of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by
Section 3.01(c). Notes in respect of which a Change in Control Purchase Notice has been
given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after
the date of the delivery of such Change in Control Purchase Notice unless such Change in
Control Purchase Notice has first been validly withdrawn as specified in the following two
paragraphs.

     (b) A Change in Control Purchase Notice may be withdrawn by means of a written notice
of withdrawal delivered to the office of the Paying Agent in accordance with the Change in
Control Purchase Notice at any time prior to the Close of Business on the Change in Control
Purchase Date specifying:

21

 

     (i) the certificate number of the Note which the Holder will deliver to be
purchased, if Certificated Notes have been issued, or notice compliant with the
relevant DTC procedures, if the Notes are not certificated,

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

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

          A written notice of withdrawal of a Change in Control Purchase Notice may be in the form set
forth in the preceding paragraph.

     Section 3.03 Deposit of Change in Control Purchase Price. Prior to 1:00 p.m. (New
York City time) on or prior to the third Business Day following the Change in Control Purchase
Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a
Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and
hold in trust as provided in Section 2.04) an amount of money (in immediately available funds if
deposited on such Trading Day) sufficient to pay the aggregate Change in Control Purchase Price of
all the Notes or portions thereof which are to be purchased as of the Change in Control Purchase
Date.

     If the Trustee or the Paying Agent holds money sufficient to pay the Change in Control
Purchase Price of a Note on the third Business Day following the Change in Control Purchase Date in
accordance with the terms hereof, then, immediately after the Change in Control Purchase Date,
interest on such Note will cease to accrue, whether or not the Note is delivered to the Trustee or the Paying Agent, and all other rights of the holder shall terminate, other than the
right to receive the Change in Control Purchase Price upon delivery of the Note.

     Section 3.04 Notes Purchased In Part. Any Note which is to be purchased only in part
shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly
authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver
to the Holder of such Note, without service charge, a new Note or Note, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to, and in exchange
for, the portion of the principal amount of the Note so surrendered that is not purchased.

     Section 3.05 Covenant To Comply With Securities Laws Upon Repurchase of Notes. When
complying with the provisions of Section 3.01 (provided, that such offer or purchase constitutes an
“issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any
successor provision thereto) under the Exchange Act at the time of such offer or purchase), and
subject to any exemptions available under applicable law, the Company shall:

22

 

     (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the
Exchange Act, as applicable;

     (b) file the related Schedule TO (or any successor schedule, form or report) if
required under the Exchange Act, as applicable;

     (c) otherwise comply with all federal and state securities laws so as to permit the
rights and obligations under Section 3.01 to be exercised in the time and in the manner
specified therein.

          To the extent that the provisions of any securities laws or regulations conflict with the
provisions of Section 3.01, the Company’s compliance with such laws and regulations shall not in
and of itself cause a breach of its obligations under Section 3.01.

ARTICLE 4

COVENANTS

     Section 4.01 Payment of Notes.

     (a) The Company agrees to pay the principal of and interest on the Notes on the dates
and in the manner provided in the Notes and the Indenture. Not later than 10:00 a.m. (New
York City time) on the due date of any principal of or interest on any Notes, or any
purchase price of the Notes, the Company will deposit with the Trustee (or Paying Agent)
money in immediately available funds sufficient to pay such amounts, provided that if the Company or any Affiliate of the Company is acting as Paying Agent, it will,
on or before each due date, segregate and hold in a separate trust fund for the benefit of
the Holders a sum of money sufficient to pay such amounts until paid to such Holders or
otherwise disposed of as provided in the Indenture. In each case the Company will promptly
notify the Trustee of its compliance with this paragraph.

     (b) An installment of principal or interest will be considered paid on the date due if
the Trustee (or Paying Agent, other than the Company or any Affiliate of the Company) holds
on that date money designated for and sufficient to pay the installment. If the Company or
any Affiliate of the Company acts as Paying Agent, an installment of principal or interest
will be considered paid on the due date only if paid to the Holders.

     (c) The Company agrees to pay interest on overdue principal, and, to the extent lawful,
overdue installments of interest at the rate per annum specified in the Notes plus 2%.

     (d) Payments in respect of the Notes represented by the Global Notes are to be made by
wire transfer of immediately available funds to the accounts specified by the Holders of the
Global Notes. With respect to Certificated Notes, the Company will make all payments by wire
transfer of immediately available funds to the accounts specified by the Holders thereof or,
if no such account is specified, by mailing a check to each Holder’s registered address.

23

 

     Section 4.02 Maintenance of Office or Agency. The Company will maintain in the United
States, an office or agency where Notes may be surrendered for registration of transfer or exchange
or for presentation for payment and where notices and demands to or upon the Company in respect of
the Notes and the Indenture may be served. The Company hereby initially designates the Corporate
Trust Office of the Trustee as such office of the Company. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such office or agency.
If at any time the Company fails to maintain any such required office or agency or fails to furnish
the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served to the Trustee.

          The Company may also from time to time designate one or more other offices or agencies where
the Notes may be surrendered or presented for any of such purposes and may from time to time
rescind such designations. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other office or agency.

     Section 4.03 Existence. The Company will do or cause to be done all things necessary
to preserve and keep in full force and effect its existence and the existence, rights and
franchises of the Company, provided that the Company is not required to preserve any such right or
franchise if the preservation thereof is no longer desirable in the conduct of the business of the
Company; and provided further that this Section does not prohibit any transaction otherwise permitted by
Section 5.01.

     Section 4.04 Rule 144A Information and Annual Reports.

     (a) At any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act,
the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon
conversion thereof shall, at such time, constitute “restricted securities” within the
meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and
shall, upon written request, provide to any Noteholder, beneficial owner or prospective
purchaser of Notes or any shares of Common Stock issued upon conversion of any Notes, the
information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to
facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under
the Securities Act.

     (b) The Company shall deliver to the Trustee, such annual reports, information,
documents and other reports that are filed with the Commission, copies of the Company’s
annual reports (which shall contain audited financial statements of the Company) and of the
information, documents and other reports (or copies of such portions of any of the foregoing
as the Commission may by rules and regulations prescribe) that the Company files with the
Commission pursuant to Section 13 or Section 15(d) of the Exchange Act when and if (and only
if) the Company makes such filings with the Commission; provided that any such information,
documents or reports required to be filed with the Commission shall be deemed delivered to
the Trustee at the same time the same is filed with the Commission. The Company shall be
deemed to have complied with the previous sentence to the extent that the Company shall have
filed or furnished such information, documents or reports to the SEC via EDGAR (or any
successor electronic

24

 

delivery procedure). In the event the Company is at any time no longer
subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act,
the Company shall continue to provide the Trustee and, upon written request, to each
Noteholder, annual and quarterly reports containing substantially the same information as
would have been required to be filed with the SEC had the Company continued to have been
subject to such reporting requirements. In such event, such annual and quarterly reports
shall be provided at substantially similar times as the Company would have been required to
provide reports had it continued to have been subject to such reporting requirements.

     Section 4.05 Reports to Trustee.

     (a) The Company will deliver to the Trustee within 120 days after the end of each
fiscal year a certificate from the principal executive, financial or accounting officer of
the Company stating that the officer has conducted or supervised a review of the activities
of the Company and its Subsidiaries and their performance under the Indenture and that,
based upon such review, the Company has fulfilled its obligations hereunder or, if there has
been a Default, specifying the Default and its nature and status.

     (b) The Company will deliver to the Trustee, as soon as possible and in any event
within 30 days after the Company becomes aware or should reasonably become aware of the occurrence of a Default, an Officers’ Certificate setting forth the details of the
Default, and the action which the Company proposes to take with respect thereto.

     Section 4.06 Stay, Extension and Usury Laws. The Company covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, which may affect the covenants or the performance
of this Indenture; and the Company (in each case, to the extent that it may lawfully do so) hereby
covenants that it will not, by resort to any such law to the extent it would hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

     Section 4.07 Payment of Additional Interest. If Additional Interest is payable by the
Company pursuant to the Registration Rights Agreement or pursuant to Section 6.02(c) of this
Indenture, the Company shall deliver to the Trustee a certificate to that effect stating (i) the
amount of such Additional Interest that is payable, (ii) the reason why such Additional Interest is
payable and (iii) the date on which such Additional Interest is payable. Unless and until a Trust
Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no
such Additional Interest is payable. If the Company has paid Additional Interest directly to the
Persons entitled to it, the Company shall deliver to the Trustee a certificate setting forth the
particulars of such payment.

ARTICLE 5

CONSOLIDATION, MERGER, SALE OR LEASE OF ASSETS

     Section 5.01 Consolidation, Merger, Sale or Lease of Assets by the Company.

25

 

     (a) The Company, without the consent of the Holders of any of the outstanding Notes,
may

     (i) consolidate with or merge with or into any Person, or

     (ii) sell, convey, transfer, or otherwise dispose of or lease all or
substantially all of its assets as an entirety or substantially an entirety, in one
transaction or a series of related transactions, to any Person; provided that

	 	(A)	 	either (x) the Company is the
continuing Person or (y) the resulting, surviving or transferee
Person is a corporation, partnership, limited liability company
or trust organized and validly existing under the laws of the
United States of America, any State thereof or the District of
Columbia and expressly assumes by supplemental indenture all of
the obligations of the Company under the Indenture and the Notes
and the Registration Rights Agreement;
	 
	 	(B)	 	immediately after giving effect
to the transaction, no Event of Default and no Default has
occurred and is continuing; and
	 
	 	(C)	 	the Company delivers to the
Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that the consolidation, merger, transfer or lease and
the supplemental indenture (if any) comply with the Indenture.

     (b) Upon the consummation of any transaction effected in accordance with these
provisions, if the Company is not the continuing Person, the resulting, surviving or
transferee Person will succeed to, and be substituted for, and may exercise every right and
power of, the Company under the Indenture and the Notes with the same effect as if such
successor Person had been named as the Company in the Indenture. Upon such substitution,
except in the case of a lease, unless the successor is one or more of the Company’s
Subsidiaries, the Company will be released from its obligations under the Indenture and the
Notes.

ARTICLE 6

DEFAULT AND REMEDIES

     Section 6.01 Events of Default. An “Event of Default” occurs with respect to the
Notes if:

     (a) the Company defaults in the payment of the principal of any Note, or any Change in
Control Purchase Price when the same becomes due and payable on the Maturity Date, on the
Change in Control Purchase Date, upon acceleration, or otherwise;

26

 

     (b) the Company fails to provide the notice required by Section 3.01(b) on a timely
basis;

     (c) the Company defaults in the payment of interest (including any Additional Interest)
on any Note when the same becomes due and payable, and the default continues for a period of
30 days;

     (d) the Company fails to comply with any other covenant or agreement of the Company in
the Indenture or the Notes and the default or breach continues for a period of 60
consecutive days after written notice to the Company by the Trustee or to the Company and
the Trustee by the Holders of 25% or more in aggregate principal amount of the Notes then
outstanding;

     (e) the Company fails to make any payment by the end of any applicable grace period
after maturity of any Debt in an amount in excess of $100,000,000 and continuance of such
failure, or (ii) there is an acceleration of Debt in an amount in excess of $100,000,000
because of a default with respect to such Debt without such Debt having been discharged or
such acceleration having been cured, waived, rescinded or annulled within a period of 30 days after written notice to the Company by the Trustee or to the
Company and the Trustee by the Holders of not less than 25% in aggregate principal amount of
the Notes then outstanding; provided, however, if any such failure or acceleration referred
to in (i) or (ii) above shall cease or be cured, waived, rescinded or annulled, then the
Event of Default by reason thereof shall be deemed not to have occurred;

     (f) the Company or any Significant Subsidiary, pursuant to or under or within the
meaning of any Bankruptcy Law, (i) commences a voluntary case or proceeding; (ii) consents
to the entry of an order for relief against it in an involuntary case or proceeding or the
commencement of any case against it; (iii) consents to the appointment of any receiver,
trustee, assignee, liquidator, custodian or similar official of it or for any substantial
part of its property; (iv) makes a general assignment for the benefit of its creditors; (v)
files a petition in bankruptcy or answer or consent seeking reorganization or relief; or
(vi) consents to the filing of such petition or the appointment of or taking possession by
any receiver, trustee, assignee, liquidator, custodian or similar official; or

     (g) a court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that (i) is for relief against the Company or any Significant Subsidiary in an
involuntary case or proceeding, or adjudicates the Company or any Significant Subsidiary
insolvent or bankrupt; (ii) appoints any receiver, trustee, assignee, liquidator, custodian
or similar official of the Company or any Significant Subsidiary or for any substantial part
of its property; or (iii) orders the winding up or liquidation of the Company or any
Significant Subsidiary, and the order or decree remains unstayed and in effect for 60 days
(an event of default specified in clause (f) or (g) a “Bankruptcy Default”).

27

 

     Section 6.02 Acceleration.

     (a) Subject to Section 6.02(c), if an Event of Default, other than a Bankruptcy Default
with respect to the Company, occurs and is continuing under the Indenture, the Trustee or
the Holders of at least 25% in aggregate of the outstanding principal amount of the Notes,
by written notice to the Company (and to the Trustee if the notice is given by the Holders),
may, and the Trustee at the request of such Holders shall, declare the principal of and
accrued interest on the Notes to be immediately due and payable. Upon a declaration of
acceleration, such principal and interest will become immediately due and payable. If a
Bankruptcy Default occurs with respect to the Company, the principal of and accrued interest
on the Notes then outstanding will become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

     (b) The Holders of a majority in principal amount of the outstanding Notes by written
notice to the Company and to the Trustee may waive all past defaults and rescind and annul
a declaration of acceleration with respect to such Notes and its consequences if

     (i) all existing Events of Default, other than the nonpayment of the principal
of, premium, if any, and interest on the Notes that have become due solely by the
declaration of acceleration, have been cured or waived, and

     (ii) the rescission would not conflict with any judgment or decree of a court
of competent jurisdiction.

     (c) Notwithstanding Section 6.02(a) or any other provision of this Indenture to the
contrary, the sole remedy for any violation of any obligations the Company may be deemed to
have pursuant to Section 314(a)(1) of the Trust Indenture Act shall be the accrual of
Additional Interest on the Notes at a rate of 0.25% per annum, payable semiannually on each
Interest Payment Date based on the number of days of the relevant interest period on which
the Company is deemed to be in violation of such section. In no event shall Additional
Interest accrue on the Notes at a per annum rate in excess of 0.25% per annum pursuant to
both this Indenture and the Registration Rights Agreement, taken together, regardless of the
number of events or circumstances giving rise to the requirement to pay such Additional
Interest.

     Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the
Trustee may pursue, in its own name or as trustee of an express trust, any available remedy by
proceeding at law or in equity to collect the payment of principal of and interest on the Notes or
to enforce the performance of any provision of the Notes or the Indenture. The Trustee may
maintain a proceeding even if it does not possess any of the Notes or does not produce any of them
in the proceeding.

     Section 6.04 Waiver of Past Defaults. Except as otherwise provided in Sections 6.02,
6.07 and 9.02(b), the Holders of a majority in principal amount of the outstanding Notes may, by
notice to the Trustee, waive an existing Default and its consequences. Upon such waiver, the
Default will cease to exist, and any Event of Default arising therefrom will be

28

 

deemed to have been
cured, but no such waiver will extend to any subsequent or other Default or impair any right
consequent thereon.

     Section 6.05 Control by Majority. The Holders of a majority in aggregate principal
amount of the outstanding Notes may 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.
However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture,
that may involve the Trustee in personal liability, or that the Trustee determines in good faith
may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such
direction, and may take any other action it deems proper that is not inconsistent with any such
direction received from Holders of Notes.

     Section 6.06 Limitation on Suits. A Holder may not institute any proceeding, judicial
or otherwise, with respect to the Indenture or the Notes, or for the appointment of a receiver or
trustee, or for any other remedy under the Indenture or the Notes, unless:

     (i) the Holder has previously given to the Trustee written notice of a
continuing Event of Default;

     (ii) Holders of at least 25% in aggregate principal amount of outstanding Notes
have made written request to the Trustee to institute proceedings in respect of the
Event of Default in its own name as Trustee under the Indenture;

     (iii) Holders have offered to the Trustee indemnity reasonably satisfactory to
the Trustee against any costs, liabilities or expenses to be incurred in compliance
with such request;

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

     (v) during such 60-day period, the Holders of a majority in aggregate principal
amount of the outstanding Notes have not given the Trustee a direction that is
inconsistent with such written request.

     Section 6.07 Rights of Holders to Receive Payment. Notwithstanding anything to the
contrary, the right of a Holder of a Note to receive payment of principal of or interest on its
Note on or after the Stated Maturities thereof, or to bring suit for the enforcement of any such
payment on or after such respective dates, may not be impaired or affected without the consent of
that Holder.

     Section 6.08 Collection Suit by Trustee. If an Event of Default in payment of
principal or interest specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust for the whole
amount of principal and accrued interest remaining unpaid, together with interest on overdue
principal and, to the extent lawful, overdue installments of interest, in each case at the rate
specified in the Notes, and such further amount as is sufficient to cover the costs and expenses of

29

 

collection, including the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and any other amounts due the Trustee hereunder.

     Section 6.09 Trustee May File Proofs of Claim. The Trustee may file proofs of claim
and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders
allowed in any judicial proceedings relating to the Company or its creditors or property, and is
entitled and empowered to collect, receive and distribute any money, securities or other property
payable or deliverable upon conversion or exchange of the Notes or upon any such claims. Any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agent and counsel, and any other amounts due the Trustee hereunder. Nothing in the
Indenture will be deemed to empower the Trustee to authorize or consent to, or accept or adopt on
behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting
the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of
the claim of any Holder in any such proceeding.

     Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article,
it shall pay out the money in the following order:

     First: to the Trustee for all amounts due hereunder;

     Second: to Holders for amounts then due and unpaid for principal of and interest on
the Notes, ratably, without preference or priority of any kind, according to the amounts due
and payable on the Notes for principal and interest; and

     Third: to the Company or as a court of competent jurisdiction may direct.

          The Trustee, upon written notice to the Company, may fix a record date and payment date for
any payment to Holders pursuant to this Section. At least 15 days before such record date, the
Trustee shall mail to each Noteholder and the Company a notice that states the record date, the
payment date and the amount to be paid.

     Section 6.11 Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted a proceeding to enforce any right or remedy under the Indenture and the proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or
to the Holder, then, subject to any determination in the proceeding, the Company, the Trustee and
the Holders will be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Company, the Trustee and the Holders will continue as
though no such proceeding had been instituted.

     Section 6.12 Undertaking for Costs. In any suit for the enforcement of any right or
remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it
as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an

30

 

undertaking to pay the costs of the suit, and the court may assess reasonable costs, including
reasonable attorneys fees, against any party litigant (other than the Trustee) in the suit having
due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section does not apply to a suit by a Holder to enforce payment of principal of or interest on any
Note on the respective due dates, or a suit by Holders of more than 10% in principal amount of the
outstanding Notes.

     Section 6.13 Rights and Remedies Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders under this
Indenture is intended to be exclusive of any other right or remedy, and all such rights and
remedies are, to the extent permitted by law, cumulative and in addition to every other right and
remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion
or exercise of any other right or remedy.

     Section 6.14 Delay or Omission Not Waiver. No delay or omission of the Trustee or of
any Holder to exercise any right or remedy accruing upon any Event of Default will impair any such
right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

ARTICLE 7

THE TRUSTEE

     Section 7.01 General.

     (a) The duties and responsibilities of the Trustee are as provided by the Trust
Indenture Act and as set forth herein. Whether or not expressly so provided, every
provision of the Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee is subject to this Article.

     (b) Except during the continuance of an Event of Default, the Trustee need perform only
those duties that are specifically set forth in the Indenture and no others, and no implied
covenants or obligations will be read into the Indenture against the Trustee. In case an
Event of Default has occurred and is continuing, the Trustee shall exercise those rights and
powers vested in it by the Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

     (c) No provision of the Indenture shall be construed to relieve the Trustee from
liability for its own negligent action, its own negligent failure to act or its own willful
misconduct.

31

 

     Section 7.02 Certain Rights of Trustee. Subject to Trust Indenture Act Sections
315(a) through (d):

     (a) In the absence of bad faith on its part, the Trustee may rely, and will be
protected in acting or refraining from acting, upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper Person. The Trustee need not investigate
any fact or matter stated in the document, but, in the case of any document which is specifically required to be furnished to the Trustee pursuant to any provision
hereof, the Trustee shall examine the document to determine whether it conforms to the
requirements of the Indenture (but need not confirm or investigate the accuracy of
mathematical calculations or other facts stated therein). The Trustee, in its discretion,
may make further inquiry or investigation into such facts or matters as it sees fit.

     (b) Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel conforming to Section 12.06 and the Trustee will not be
liable for any action it takes or omits to take in good faith in reliance on the certificate
or opinion.

     (c) The Trustee may act through its attorneys and agents and will not be responsible
for the misconduct or negligence of any agent appointed with due care.

     (d) The Trustee will be under no obligation to exercise any of the rights or powers
vested in it by the Indenture at the request or direction of any of the Holders, unless such
Holders have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities that might be incurred by it in compliance with such request or
direction.

     (e) The Trustee will not be liable for any action it takes or omits to take in good
faith that it believes to be authorized or within its rights or powers or for any action it
takes or omits to take in accordance with the direction of the Holders in accordance with
Section 6.05 relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under the Indenture.

     (f) The Trustee may consult with counsel, and the written advice of such counsel or any
Opinion of Counsel will be full and complete authorization and protection in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

     (g) No provision of the Indenture will require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of its duties hereunder,
or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it
against any loss, liability or expense.

     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

32

 

Company or
its Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the
same with like rights. However, the Trustee is subject to Trust Indenture Act Sections 310(b) and
311. For purposes of Trust Indenture Act Section 311(b)(4) and (6):

     (a) “cash transaction” means any transaction in which full payment for goods or
securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon
demand; and

     (b) “self-liquidating paper” means any draft, bill of exchange, acceptance or
obligation which is made, drawn, negotiated or incurred for the purpose of financing the
purchase, processing, manufacturing, shipment, storage or sale of goods, wares or
merchandise and which is secured by documents evidencing title to, possession of, or a lien
upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale
of the goods, wares or merchandise previously constituting the security, provided the
security is received by the Trustee simultaneously with the creation of the creditor
relationship arising from the making, drawing, negotiating or incurring of the draft, bill
of exchange, acceptance or obligation.

     Section 7.04 Trustee’s Disclaimer. The Trustee (i) makes no representation as to the
validity or adequacy of the Indenture or the Notes, (ii) is not accountable for the Company’s use
or application of the proceeds from the Notes and (iii) is not responsible for any statement in the
Notes other than its certificate of authentication.

     Section 7.05 Notice of Default. If any Default occurs and is continuing and is known
to the Trustee, the Trustee will send notice of the Default to each Holder within 90 days after it
occurs, unless the Default has been cured; provided that, except in the case of a default in the
payment of the principal of or interest on any Note, the Trustee may withhold the notice if and so
long as the board of directors, the executive committee or a trust committee of directors of the
Trustee in good faith determines that withholding the notice is in the interest of the Holders.
Notice to Holders under this Section will be given in the manner and to the extent provided in
Trust Indenture Act Section 313(c).

     Section 7.06 Reports by Trustee to Holders. Within 60 days after each May 15,
beginning with May 15, 2007, the Trustee will mail to each Holder, as provided in Trust Indenture
Act Section 313(c), a brief report dated as of such May 15, if required by Trust Indenture Act
Section 313(a), and file such reports with each stock exchange upon which its Notes are listed and
with the Commission as required by Trust Indenture Act Section 313(d).

     Section 7.07 Compensation and Indemnity.

     (a) The Company will pay the Trustee compensation as agreed upon in writing for its
services. The compensation of the Trustee is not limited by any law on compensation of a
Trustee of an express trust. The Company will reimburse the Trustee upon request for all
reasonable out-of-pocket expenses, disbursements and advances incurred or made by the
Trustee, including the reasonable compensation and expenses of the Trustee’s agents and
counsel.

33

 

     (b) The Company will indemnify the Trustee for, and hold it harmless against, any loss
or liability or expense incurred by it without negligence or bad faith on its part arising
out of or in connection with the acceptance or administration of the Indenture and its
duties under the Indenture and the Notes, including the costs and expenses of defending
itself against any claim or liability and of complying with any process served upon it or
any of its officers in connection with the exercise or performance of any of its powers or
duties under the Indenture and the Notes.

     (c) To secure the Company’s payment obligations in this Section, the Trustee will have
a lien prior to the Notes on all money or property held or collected by the Trustee, in its
capacity as Trustee, except money or property held in trust to pay principal of, and
interest on particular Notes.

     Section 7.08 Replacement of Trustee.

     (a) (i) The Trustee may resign at any time by written notice to the Company.

     (ii) The Holders of a majority in principal amount of the outstanding Notes may
remove the Trustee by written notice to the Trustee.

     (iii) If the Trustee is no longer eligible under Section 7.10 or in the
circumstances described in Trust Indenture Act Section 310(b), any Holder that
satisfies the requirements of Trust Indenture Act Section 310(b) may petition any
court of competent jurisdiction for the removal of the Trustee and the appointment
of a successor Trustee.

     (iv) The Company may remove the Trustee if: (A) the Trustee is no longer
eligible under Section 7.10; (B) the Trustee is adjudged a bankrupt or an insolvent;
(C) a receiver or other public officer takes charge of the Trustee or its property;
or (D) the Trustee becomes incapable of acting.

A resignation or removal of the Trustee and appointment of a successor Trustee will become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

     (b) If the Trustee has been removed by the Holders, Holders of a majority in principal
amount of the Notes may appoint a successor Trustee with the consent of the Company.
Otherwise, if the Trustee resigns or is removed, or if a vacancy exists in the office of
Trustee for any reason, the Company will promptly appoint a successor Trustee. If the
successor Trustee does not deliver its written acceptance within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a
majority in principal amount of the outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

     (c) Upon delivery by the successor Trustee of a written acceptance of its appointment
to the retiring Trustee and to the Company, (i) the retiring Trustee will transfer all
property held by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07(c), (ii) the resignation or removal of the retiring Trustee will

34

 

become effective, and (iii) the successor Trustee will have all the rights, powers and
duties of the Trustee under the Indenture. Upon request of any successor Trustee, the
Company will execute any and all reasonable instruments for fully and vesting in and
confirming to the successor Trustee all such rights, powers and trusts. The Company will
give notice of any resignation and any removal of the Trustee and each appointment of a
successor Trustee to all Holders, and include in the notice the name of the successor
Trustee and the address of its Corporate Trust Office.

     (d) Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

     (e) The Trustee agrees to give the notices provided for in, and otherwise comply with,
Trust Indenture Act Section 310(b).

     Section 7.09 Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate trust business (including the
administration of this Indenture) to, another corporation or national banking association, the
resulting, surviving or transferee corporation or national banking association without any further
act will be the successor Trustee with the same effect as if the successor Trustee had been named
as the Trustee in the Indenture.

     Section 7.10 Eligibility. The Indenture must always have a Trustee that satisfies the
requirements of Trust Indenture Act Section 310(a) and has a combined capital and surplus of at
least $25,000,000 as set forth in its most recent published annual report of condition.

     Section 7.11 Money Held in Trust. The Trustee will not be liable for interest on any
money received by it except as it may agree with the Company. Money held in trust by the Trustee
need not be segregated from other funds except to the extent required by law and except for money
held in trust under Article 8.

ARTICLE 8

DISCHARGE

     Section 8.01 Satisfaction and Discharge of the Indenture.

     (a) This Indenture shall cease to be of further effect if either: (i) all outstanding
Notes (other than Notes replaced pursuant to Section 2.07) have been delivered to the
Trustee for cancellation or (ii) all outstanding Notes have become due and payable on the
Maturity Date or upon repurchase pursuant to Article 3, and the Company irrevocably
deposits, prior to the applicable date on which such payment is due and payable, with the
Trustee or the Paying Agent (if the Paying Agent is not the Company or any of its
Affiliates) Cash, and, if applicable as herein provided and in accordance herewith, such other consideration, sufficient to pay all amounts due and owing on all outstanding
Notes (other than Notes replaced pursuant to Section 2.07) on the Maturity Date or the
Change

35

 

in Control Purchase Date, as the case may be; provided that, in either case, the
Company pays to the Trustee all other sums payable hereunder by the Company.

     (b) The Company may exercise its satisfaction and discharge option with respect to the
Notes only if:

     (i) no Default or Event of Default with respect to the Notes shall exist on the
date of such deposit;

     (ii) such deposit shall not result in a breach or violation of, or constitute a
Default or Event of Default under, this Indenture or any other agreement or
instrument to which the Company is a party or by which it is bound; and

     (iii) the Company has delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence
of Defaults and Events of Default and as to any factual matters), each stating that
all conditions precedent provided for herein relating to the satisfaction and
discharge of this Indenture have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Company to the Trustee under Section 7.07 shall survive and, if money shall have been deposited
with the Trustee pursuant to clause (a) of this Section, the provisions of Section 2.03, Section
2.04, Section 2.05, Section 2.06, Section 2.07, Section 2.12, Section 3.01, Article 5, Article 10
and this Article 8, shall survive and the Company shall be required to make all payments and
deliveries required by such Sections or Articles, as the case may be, irrespective of any prior
satisfaction and discharge until the Notes have been paid in full.

     Section 8.02 Application of Trust Money. Subject to the provisions of Section 8.03,
the Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money
deposited with it pursuant to Section 8.01 and shall apply the deposited money in accordance with
this Indenture and the Notes to the payment of the principal amount of and interest on the Notes.

     Section 8.03 Repayment to Company. The Trustee and each Paying Agent shall promptly
pay to the Company upon request any excess money (x) deposited with them pursuant to Section 8.01
and (y) held by them at any time.

The Trustee and each Paying Agent shall also pay to the Company upon request any money held by them
for the payment of the principal amount of Notes or interest thereon that remains unclaimed for two
years after a right to such money has matured (which maturity shall occur, for the avoidance of
doubt, on the Maturity Date or the Change in Control Purchase Date (with respect to any Notes
repurchased pursuant to Article 3)); provided, however, that the Trustee or such Paying Agent, before being required to make any such payment, may at the expense of the
Company cause to be mailed to each Holder entitled to such money or publish in a newspaper of
general circulation in the City of New York notice that such money remains unclaimed and that after
a date specified therein, which shall be at least 30 days from the date of such mailing or
publication, any unclaimed balance of such money then remaining will be repaid to the

36

 

Company.
After payment to the Company, Holders entitled to money must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another person.

     Section 8.04 Reinstatement. If the Trustee or any Paying Agent is unable to apply any
money in accordance with Section 8.02 by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then 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 such Paying Agent is permitted to apply all such money in accordance with Section
8.02; provided, however, that if the Company has made any payment of the principal amount of or
interest on any Notes because of the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive any such payment from the money
held by the Trustee or such Paying Agent.

ARTICLE 9

AMENDMENTS, SUPPLEMENTS AND WAIVERS

     Section 9.01 Amendments Without Consent of Holders. The Company and the Trustee may
amend or supplement the Indenture or the Notes without notice to or the consent of any Noteholder:

     (a) to cure any ambiguity, omission, defect or inconsistency in the Indenture or the
Notes;

     (b) to comply with Article 5 or Section 10.12;

     (c) to comply with the Trust Indenture Act or any amendment thereto, or to comply with
any requirements of the Commission in connection with the qualification of the Indenture
under the Trust Indenture Act;

     (d) to evidence and provide for the acceptance of an appointment hereunder by a
successor Trustee;

     (e) to provide for uncertificated Notes in addition to or in place of certificated
Notes;

     (f) to secure the Notes;

     (g) to add guarantees with respect to the Notes;

     (h) to add to the covenants of the Company for the benefit of the Holders or to
surrender any right or power herein conferred upon the Company;

     (i) to add any additional Events of Default;

     (j) to comply with the rules of any applicable securities depositary; or

37

 

     (k) to make any other change that does not materially adversely affect the rights of
any Holder.

     Section 9.02 Amendments With Consent of Holders.

     (a) Except as otherwise provided in Section 6.07 or paragraph (b), the Company and the
Trustee may amend the Indenture and the Notes with the written consent of the Holders of a
majority in principal amount of the outstanding Notes, and the Holders of a majority in
principal amount of the outstanding Notes by written notice to the Trustee may waive future
compliance by the Company with any provision of the Indenture or the Notes.

     (b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder
affected, an amendment or waiver may not

     (i) reduce the principal amount of, Change in Control Purchase Price with
respect to, or any premium or interest payment on any Note,

     (ii) make any Note payable in currency or securities other than that stated in
the Note,

     (iii) change the Stated Maturities of any installment of principal of any Note,

     (iv) make any change that adversely affects the Holders’ right to convert any
Note,

     (v) make any change that adversely affects the Holders’ right to require the
Company to purchase the Notes in accordance with the terms thereof and this
Indenture,

     (vi) impair the right to convert or receive any principal or interest payment
with respect to, a Note, or right to institute suit for the enforcement of any
payment with respect to, or conversion of, the Notes, or

     (vii) make any change in the percentage of the principal amount of the Notes
required for amendments or waivers.

     (c) It is not necessary for Noteholders to approve the particular form of any proposed
amendment, supplement or waiver, but is sufficient if their consent approves the substance
thereof.

     (d) An amendment, supplement or waiver under this Section will become effective on
receipt by the Trustee of written consents from the Holders of the requisite percentage in
principal amount of the outstanding Notes. After an amendment, supplement or waiver under
this Section becomes effective, the Company will send to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. The Company will send
supplemental indentures to Holders upon request. Any

38

 

failure of the Company to send such
notice, or any defect therein, will not, however, in any way impair or affect the validity
of any such supplemental indenture or waiver.

     (e) With respect to the amendments set forth in Section 9.01 and this Section 9.02, no
such amendment to cure any ambiguity, defect or inconsistency made solely to conform the
Indenture to the provisions of the description of the Notes as set forth in any final
offering memorandum will be deemed to adversely affect the interests of the Noteholders.

     Section 9.03 Effect of Consent.

     (a) After an amendment, supplement or waiver becomes effective, it will bind every
Holder unless it is of the type requiring the consent of each Holder affected. If the
amendment, supplement or waiver is of the type requiring the consent of each Holder
affected, the amendment, supplement or waiver shall bind each Holder that has consented to
it and every subsequent Holder of a Note that evidences the same debt as the Note of the
consenting Holder.

     (b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may
require the Holder to deliver it to the Trustee so that the Trustee may place an appropriate
notation of the changed terms on the Note and return it to the Holder, or exchange it for a
new Note that reflects the changed terms. The Trustee may also place an appropriate
notation on any Note thereafter authenticated. However, the effectiveness of the amendment,
supplement or waiver is not affected by any failure to annotate or exchange Notes in this
fashion.

     Section 9.04 Trustee’s Rights and Obligations. The Trustee is entitled to receive,
and will be fully protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted
by the Indenture. If the Trustee has received such an Opinion of Counsel, it shall sign the
amendment, supplement or waiver so long as the same does not adversely affect the rights of the
Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver
that affects the Trustee’s own rights, duties or immunities under the Indenture.

     Section 9.05 Conformity With Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act.

     Section 9.06 Payments for Consents. Neither the Company nor any of its Subsidiaries
or Affiliates may, directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration
is offered to be paid or agreed to be paid to all Holders of the Notes that consent, waive or agree
to amend such term or provision within the time period set forth in the solicitation documents
relating to the consent, waiver or amendment.

ARTICLE 10

CONVERSION

     Section 10.01 Conversion Privilege. A Holder of a Note may convert such Note at any
time on or prior to the Close of Business on the Business Day immediately preceding the Maturity
Date upon the occurrence of any of the events set forth in paragraph 7(a), paragraph 7(b),
paragraph 7(c), paragraph 7(d) or paragraph 7(e) of the Notes, subject to the provisions of this
Article 10. Except as set forth below under Section 10.11, if a Holder surrenders its Notes for
conversion, such Holder will receive, in respect of each $1,000 of principal amount of Notes to be
converted:

     (a) Cash in an amount equal to the lesser of (A) $1,000 and (B) the Conversion Value
(the “Required Cash Amount”), and

     (b) if the Conversion Value is greater than $1,000, a number of shares of Common Stock
(the “Remaining Shares”), equal to the sum of the Daily Share Amounts for each of the twenty
consecutive Trading Days in the Conversion Reference Period, subject to the right of the
Company to deliver Cash in lieu of all or a portion of such Remaining Shares as described
below.

          By the Close of Business on the Business Day prior to the first scheduled Trading Day of the
applicable Conversion Reference Period, the Company may specify a percentage of the Daily Share
Amount that will be settled in Cash (the “Cash Percentage”) and will notify the Noteholder of such
Cash Percentage through written notice to the Trustee (the “Cash Percentage Notice”). If the
Company elects to specify a Cash Percentage, (x) the amount of Cash that the Company will deliver
pursuant to clause (b) of this Section 10.01 in respect of each Trading Day in the applicable
Conversion Reference Period will equal the product of: (i) the Cash Percentage, (ii) the Daily
Share Amount for such Trading Day, and (iii) the Volume Weighted Average Price of the Common Stock
for such Trading Day and (y) the number of shares of Common Stock deliverable in respect of each
Business Day in the applicable Conversion Reference Period (in lieu of the full Daily Share Amount
for such Trading Day pursuant to clause (b) above) will be a percentage of the Daily Share Amount
equal to 100% minus the Cash Percentage. If the Company does not specify a Cash Percentage by the Close of Business on the Trading Day prior
to the first scheduled Trading Day of the applicable Conversion Reference Period, the Company shall
settle 100% of the Daily Share Amount for each Trading Day in the applicable Conversion Reference
Period with shares of Common Stock; provided, however, that the Company will pay Cash in lieu of
fractional shares otherwise issuable upon conversion of such Note, pursuant to Section 10.03
hereof. The Company may, at its option, revoke any Cash Percentage Notice through written notice
to the Trustee by the Close of Business on the Business Day prior to the scheduled first Trading
Day of the applicable Conversion Reference Period.

     (c) A Holder may convert a portion of the principal amount of a Note if the portion is
$1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to
conversion of all of a Note also apply to conversion of a portion of a Note.

40

 

     (d) In the event of a stock split, combination, dividend or any other event resulting
in an adjustment to the Conversion Rate pursuant to Section 10.06, 10.07, 10.08, 10.09 or
10.10, during the applicable Conversion Reference Period, appropriate adjustment to the
equation for calculating Conversion Value and Remaining Shares shall be made, as determined
by the Board of Directors.

     (e) Notes with respect to which a Change in Control Purchase Notice has been given by
the Holder may be converted pursuant to this Article 10 only if the Change in Control
Purchase Notice has been withdrawn in accordance with Section 3.02.

     (f) Whenever any event described in paragraph 7(a), paragraph 7(b), paragraph 7(c),
paragraph 7(d) or paragraph 7(e) of the Notes shall occur such that the Notes become
convertible as provided in this Article 10, the Company shall (x) issue a press release and
use its reasonable efforts to post such information on its website or otherwise publicly
disclose this information or (y) promptly deliver, in accordance with Section 12.03, written
notice of the convertibility of the Notes to the Trustee and each Noteholder and to the
Conversion Agent for the benefit of the Noteholders, which press release, website posting,
public disclosure or written notice, as the case may be, shall include:

     (i) a description of such event;

     (ii) a description of the periods during which the Notes shall be convertible
as provided in paragraph 7(a), paragraph 7(b), paragraph 7(c), paragraph 7(d) or
paragraph 7(e) of the Notes as a result of such event;

     (iii) a statement of whether an adjustment to the Conversion Rate shall take
effect in respect of such event pursuant to Section 10.13; and

     (iv) the procedures Noteholders must follow to convert their Notes in
accordance with this Article 10, including the name and address of the Conversion
Agent.

     Section 10.02 Conversion Procedure.

     (a) To convert a Note represented by a Global Note, a Noteholder must convert by
book-entry transfer to the Conversion Agent through the facilities of the DTC. To convert a
Note that is represented by a Certificated Note, a Noteholder must (1) complete and manually
sign a Conversion Notice, a form of which is on the back of the Note, and deliver such
Conversion Notice to the Conversion Agent, (2) surrender the Note to the Conversion Agent,
(3) if required by the Conversion Agent, furnish appropriate endorsement and transfer
documents, and (4) if required, pay all transfer or similar taxes. The Conversion Agent
shall, within one (1) Business Day of any Conversion Date, provide notice to the Company, as
set forth in Section 12.03, of the occurrence of such Conversion Date.

     (b) As promptly as practicable following the end of the Conversion Reference Period
applicable to the Notes being converted, the Company shall deliver to the Holder, through
the Conversion Agent, the Required Cash Amount and Remaining Shares, if any

41

 

(including Cash
in lieu of Remaining Shares pursuant to Section 10.01 hereof and Cash in lieu of fractional
shares pursuant to Section 10.03 hereof). The person in whose name the certificate
representing any shares is registered shall be treated as a stockholder of record on and
after the last Trading Day of the Conversion Reference Period; provided,
however, that no surrender of a Note on any date when the stock transfer books of
the Company shall be closed shall be effective to constitute the person or persons entitled
to receive the Remaining Shares upon such conversion as the record holder or holders of such
shares of Common Stock on such date, but such surrender 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 person shall no
longer be a Holder of such Note.

     (c) No payment or adjustment will be made for dividends on, or other distributions with
respect to, any Common Stock except as provided in this Article 10. Upon conversion of a
Note, a Noteholder will not receive, except as described below, any Cash payment
representing accrued interest. Instead, accrued interest will be deemed paid by the Cash
and/or shares of common stock, if any, received by the Noteholder upon conversion. Delivery
to the Noteholder of such Cash and/or shares of Common Stock will thus be deemed (1) to
satisfy the Company’s obligation to pay the principal amount of a Note, and (2) to satisfy
the Company’s obligation to pay accrued and unpaid interest on the Note. As a result, upon
conversion of a Note, accrued and unpaid interest on such Note is deemed paid in full rather
than cancelled, extinguished or forfeited.

     (d) Holders of Notes surrendered for conversion during the period from the Close of
Business on any Regular Record Date next preceding any Interest Payment Date to the opening
of business of such Interest Payment Date will receive the semiannual interest payable on
such Notes on the corresponding Interest Payment Date notwithstanding the conversion, and
such Notes upon surrender must be accompanied by funds equal to the amount of such payment;
provided that no such payment need be made (x) in connection with any conversion following
the Regular Record Date immediately preceding the Maturity Date, (y) if the Company has specified a Change in Control Purchase Date that
is after a Regular Record Date and on or prior to the corresponding Interest Payment Date or
(z) to the extent of any Defaulted Interest, if any Defaulted Interest exists at the time of
conversion with respect to such Note. The Company shall not be required to convert any Notes
that are surrendered for conversion without payment of interest as required by this
paragraph.

     (e) If the Holder converts more than one Note at the same time, the Required Cash
Amount and the Remaining Shares, if any (together with the Cash payment, if any, in lieu of
fractional shares) shall be based on the total principal amount of the Notes converted.

     (f) If the last day on which a Note may be converted is a Legal Holiday, the Note may
be surrendered on the next succeeding day that is not a Legal Holiday.

42

 

     (g) Upon surrender of a Note that is converted in part, 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 unconverted portion of the Note surrendered.

     Section 10.03 Fractional Shares. The Company will not issue a fractional share of
Common Stock upon conversion of a Note. Instead, the Company will deliver Cash in lieu of a
fractional share based on arithmetic average of the Volume Weighted Average Price of Common Stock
for each of the twenty consecutive Trading Days of the Conversion Reference Period, rounded to the
nearest whole cent (the “Average Price”).

     Section 10.04 Taxes On Conversion. If a Holder converts a Note, the Company shall pay
any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common
Stock upon the conversion. However, the Holder shall pay any such tax which is due because the
Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion
Agent may refuse to deliver the certificates representing the Common Stock being issued in a name
other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax
which will be due because the Common Stock is to be delivered in a name other than the Holder’s
name. Nothing herein shall preclude any tax withholding required by law or regulations.

     Section 10.05 Company To Provide Common Stock.

          The Company shall, prior to issuance of any Notes under this Article 10, and from time to time
as may be necessary, reserve out of its authorized but unissued Common Stock a sufficient number of
shares of Common Stock to permit the delivery in respect of all outstanding Notes of the number of
Remaining Shares due upon conversion (assuming, for purposes of this sentence, that the Company
elects to deliver solely shares of Common Stock in respect of its obligation to deliver the
Remaining Shares).

          All shares of Common Stock delivered upon payment of the Remaining Shares, if applicable, upon
conversion of the Notes shall be newly issued shares or treasury shares, shall be duly and validly
issued and fully paid and nonassessable and shall be free from preemptive rights and free of any
lien or adverse claim.

          The Company will comply with all federal and state securities laws regulating the offer and
delivery of shares of Common Stock upon payment of the Remaining Shares, if applicable, upon
conversion of Notes, if any, and will list or cause to have quoted such shares of Common Stock on
each national securities exchange or in the over-the-counter market or such other market on which
the Common Stock is then listed or quoted.

          In addition, if any shares of Common Stock which would be issuable upon conversion of Notes
hereunder require registration with or approval of any governmental authority before such shares of
Common Stock may be issued upon such conversion, the Company will cause such shares of Common Stock
to be duly registered or approved, as the case may be.

43

 

     Section 10.06 Adjustment for Change In Capital Stock.

      (a) If the Company shall, at any time and from time to time while any of the Notes are
outstanding, issue a dividend or makes a distribution on its Common Stock payable in shares
of its Common Stock, then the Conversion Rate at the opening of business on the Ex-Dividend
Date for such dividend or distribution will be adjusted by multiplying such Conversion Rate
by a fraction:

     (i) the numerator of which shall be the sum of the number of shares of Common
Stock outstanding at the Close of Business on the Business Day immediately preceding
the Ex-Dividend Date for such dividend or distribution, plus the total number of shares of Common Stock constituting such dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding at the close of business on the Business Day immediately preceding such
Ex-Dividend Date.

          If any dividend or distribution of the type described in this Section 10.06(a) is declared but
not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would
then be in effect if such dividend or distribution had not been declared. Except as set forth in
the preceding sentence, in no event shall the Conversion Rate be decreased pursuant to this Section
10.06(a).

     (b) If the Company shall, at any time or from time to time while any of the Notes are
outstanding, subdivide or reclassify its outstanding shares of Common Stock into a greater
number of shares of Common Stock, then the Conversion Rate in effect at the opening of
business on the day upon which such subdivision becomes effective shall be proportionately
increased, and conversely, if the Company shall, at any time or from time to time while any
of the Notes are outstanding, combine or reclassify its outstanding shares of Common Stock
into a smaller number of shares of Common Stock, then the Conversion Rate in effect at the opening of business on the day upon which such
combination or reclassification becomes effective shall be proportionately decreased. In
each such case, the Conversion Rate shall be adjusted by multiplying such Conversion Rate by
a fraction, the numerator of which shall be the number of shares of Common Stock outstanding
immediately after giving effect to such subdivision, combination or reclassification and the
denominator of which shall be the number of shares of Common Stock outstanding immediately
prior to such subdivision or combination. Such increase or reduction, as the case may be,
shall become effective immediately after the opening of business on the day upon which such
subdivision, combination or reclassification becomes effective.

     Section 10.07 Adjustment for Rights Issue. If the Company shall, at any time or from
time to time while the Notes are outstanding, distribute rights to all holders of its Common Stock
entitling them, for a period expiring within 60 days after the record date for such distribution,
to purchase shares of Common Stock at less than the average of the Closing Prices for the five
consecutive Trading Days immediately preceding the first public announcement of

44

 

the distribution,
the Conversion Rate shall be adjusted so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect at the opening of business on the Ex-Dividend Date for
such distribution by a fraction:

	 	(x)	 	the numerator of which shall be the number of shares of Common
Stock outstanding at the close of business on the Business Day immediately
preceding the Ex-Dividend Date for such distribution, plus the total number of
additional shares of Common Stock so offered for purchase; and
	 
	 	(y)	 	the denominator of which shall be the number of shares of
Common Stock outstanding on the close of business on the Business Day
immediately preceding the Ex-Dividend Date for such distribution, plus the
number of shares of Common Stock that the aggregate offering price of the total
number of shares of Common Stock so offered would purchase at the Current
Market Price of the Common Stock on the declaration date for such distribution
(determined by multiplying such total number of shares of Common Stock so
offered by the exercise price of such rights and dividing the product so
obtained by such Current Market Price).

          Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such distribution.

          To the extent that shares of Common Stock are not delivered pursuant to such rights or upon
the expiration or termination of such rights, 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 been made on the basis of the delivery of only the number of shares of Common Stock actually
delivered. In the event that such rights are not so distributed, the Conversion Rate shall again
be adjusted to be the Conversion Rate which would then be in effect if the Ex-Dividend Date for
such distribution had not occurred. In determining whether any rights entitle the holders to purchase shares of Common Stock at less than the average of the
Closing Prices for the five consecutive Trading Days immediately preceding the first public
announcement of the relevant distribution, and in determining the aggregate offering price of such
shares of Common Stock, there shall be taken into account any consideration received for such
rights and the value of such consideration if other than Cash, to be determined in good faith by
the Board of Directors. Except as set forth in this paragraph, in no event shall the Conversion
Rate be decreased pursuant to this Section 10.07.

     Section 10.08 Adjustment for Other Distributions.

     (a) If the Company shall, at any time or from time to time while the Notes are
outstanding, distribute to all holders of its Common Stock any of its Capital Stock, assets,
or debt securities or any rights, warrants or options to purchase securities of the Company
(excluding (w) any distribution of Capital Stock of, or similar equity interests in, a
Subsidiary or other business unit of the Company referred to in Section 10.08(b) below, (x)
any distributions described in Section 10.06(a) above, (y) any rights described in Section
10.07 above, (z) any cash dividends or other cash distributions referred to in

45

 

Section 10.09
below) (such Capital Stock, assets, debt securities or rights to purchase securities of the
Company being distributed hereinafter in this Section 10.08 called the “Distributed
Assets”), the Conversion Rate shall be increased so that the same shall be equal to the rate
determined by multiplying the Conversion Rate in effect immediately prior to the opening of
business on the Ex-Dividend Date with respect to such distribution by a fraction:

     (i) the numerator of which will be the Current Market Price of the Common
Stock, and

     (ii) the denominator of which will be the Current Market Price of the Common
Stock minus the fair market value, as determined by the Board of Directors, of the
portion of Distributed Assets so distributed applicable to one share of the Common
Stock (determined on the basis of the number of shares of Common Stock outstanding
on such Ex-Dividend Date).

          Such increase shall become effective immediately after the opening of business on the
Ex-Dividend Date for such distribution. In the event that such distribution is not so made, the
Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if
such distribution had not been declared. Except as set forth in the prior sentence, in no event
shall the Conversion Rate be decreased pursuant to this Section 10.08(a).

          If the Board of Directors determines the fair market value of any distribution for purposes of
this Section 10.08(a) by reference to the actual or when issued trading market for any Distributed
Assets comprising all or part of such distribution, it must in doing so consider the prices in such
market over the same period (the “Reference Period”) used in computing the Current Market Price for
purposes of clause (i) above, unless the Board of Directors determines in good faith that
determining the fair market value during the Reference Period would not be in the best interest of
the Holders.

     (b) With respect to an adjustment pursuant to this Section 10.08 where there has been a
payment of a dividend or other distribution on Common Stock of shares of capital stock of,
or similar equity interests in, a subsidiary or other business unit of the Company, the
Conversion Rate will be adjusted by multiplying the Conversion Rate in effect immediately
prior to the close of business on the record date with respect to such distribution by a
fraction:

     (i) the numerator of which shall be (a) the average of the closing sale prices
of the capital stock or similar equity interest distributed to holders of Common
Stock applicable to one share of Common Stock over the five Trading Days commencing
on and including the fifth Trading Day after the Ex-Dividend Date for such dividend
or distribution on the principal national securities exchange or inter-dealer
quotation system on which such securities are then listed or traded, plus (b) the
average of the Closing Prices over the five Trading Days commencing on and including
the fifth Trading Day after the Ex-Dividend Date for such dividend or distribution
(the “Average Sale Price”), and

46

 

     (ii) the denominator of which shall be the Average Sale Price.

     Section 10.09 Adjustment for Cash Dividends. If the Company shall, at any time or
from time to time while any of the Notes are outstanding, by dividend or otherwise, distribute to
all or substantially all holders of its shares of Common Stock, Cash (excluding (x) any
distributions described in Section 10.10 below or (y) any dividend or distribution in connection
with the Company’s liquidation, dissolution or winding up), then the Conversion Rate shall be
adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the opening of business of the Ex-Dividend Date for such distribution
by a fraction:

	 	(x)	 	the numerator of which shall be equal to the
Current Market Price per share of Common Stock; and
	 
	 	(y)	 	the denominator of which shall be equal to the
Current Market Price per share of Common Stock on such date, less the
amount of the distribution per share of Common Stock.

                   Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such distribution. In the event that such distribution is not so made, the
Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if
such dividend or distribution had not been declared.

     Section 10.10 Adjustment for Certain Tender Offers. In case the Company or any of its
Subsidiaries shall, at any time or from time to time, while any of the Notes are outstanding,
distribute Cash or other consideration in respect of a tender offer or exchange offer made by the
Company or any Subsidiary for all or any portion of the Common Stock, where the sum of the
aggregate amount of such Cash distributed and the aggregate fair market value (as determined in
good faith by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), as of the Expiration
Date (as defined below), of such other consideration distributed (such sum, the “Aggregate Amount”)
expressed as an amount per share of Common Stock validly tendered or exchanged, and not withdrawn,
pursuant to such tender offer or exchange offer as of the Expiration Time (as defined below) (such
tendered or exchanged shares of Common Stock, the “Purchased Shares”) exceeds the Closing Price per
share of the Common Stock on the first Trading Day immediately following the last date (such last
date, the “Expiration Date”) on which tenders or exchanges could have been made pursuant to such
tender offer or exchange offer (as the same may be amended through the Expiration Date), then, and
in each case, immediately after the close of business on such date, the Conversion Rate shall be
increased so that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the close of business on the Trading Day immediately following the
Expiration Date by a fraction:

	 	(x)	 	the numerator of which is equal to the sum of
(A) the Aggregate Amount and (B) the product of (I) an amount equal to
(1) the number of shares of Common Stock outstanding as of the last
time (the “Expiration Time”) at which tenders or exchanges could have
been made pursuant to such tender offer or exchange offer less (2)

47

 

	 	 	 	the
Purchased Shares and (II) the Closing Price per share of the Common
Stock on the first Trading Day immediately following the Expiration
Date; and
	 
	 	(y)	 	the denominator of which shall be equal to the
product of (A) the number of shares of Common Stock outstanding as of
the Expiration Time (including all Purchased Shares) and (B) the
Closing Price per share of the Common Stock on the first Trading Day
immediately following the Expiration Date.

An adjustment, if any, to the Conversion Rate pursuant to this Section 10.10 shall become effective
immediately prior to the opening of business on the second Trading Day immediately following the
Expiration Date. In the event that the Company or a Subsidiary is obligated to purchase shares of
Common Stock pursuant to any such tender offer or exchange offer, but the Company or such
Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all
such purchases are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion
Rate which would then be in effect if such tender offer or exchange offer had not been made.
Except as set forth in the preceding sentence, if the application of this Section 10.10 to any
tender offer or exchange offer would result in a decrease in the Conversion Rate, no adjustment
shall be made for such tender offer or exchange offer under this Section 10.10.

     Section 10.11 Provisions Governing Adjustment to Conversion Rate. Rights or warrants
distributed by the Company to all holders of Common Stock entitling the holders thereof to
subscribe for or purchase shares of the Company’s Capital 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 Common Stock; (ii)
are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of
Section 10.06, Section 10.07, Section 10.08, Section 10.09 or Section 10.10 (and no adjustment to
the Conversion Rate under Section 10.06, Section 10.07, Section 10.08, Section 10.09 or Section
10.10 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights,
options 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 Section 10.08, except as set forth in
Section 10.23. 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), except as set forth in
Section 10.23. In addition, except as set forth in Section 10.23, 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 Section
10.06, Section 10.07, Section 10.08, Section 10.09 or Section 10.10 was made (including any
adjustment contemplated in Section 10.23), (1) in the case of any such rights, options or warrants

48

 

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, options
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.

     Section 10.12 Disposition Events. If any of the following events (any such event, a
“Disposition Event”) occurs:

     (a) any reclassification of the 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
subdivision or combination);

     (b) any merger, consolidation or other combination involving the Company; or

     (c) any sale or conveyance of all or substantially all the properties and assets of the
Company to any other Person;

in each case, as a result of which all of the holders of Common Stock shall be entitled to receive
Cash, securities or other property for their shares of Common Stock, the Company or the successor
or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture
(which shall comply with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture, if such supplemental indenture is then required to so comply) providing that notwithstanding the provisions of Section 10.01, and subject to the
provisions of paragraph 7 of the Notes, the Conversion Value with respect to each $1,000 principal
amount of Notes converted following the effective date of any Disposition Event, shall be
calculated based on the kind and amount of Cash, securities or other property (collectively,
“Reference Property”) received upon the occurrence of such Disposition Event by a holder of Common
Stock holding, immediately prior to the transaction, a number of shares of Common Stock equal to
the Conversion Rate immediately prior to such Disposition Event; provided that if the Disposition
Event provides the holders of Common Stock with the right to receive more than a single type of
consideration determined based in part upon any form of stockholder election, the Reference
Property shall be comprised of the weighted average of the types and amounts of consideration
received by the holders of the Common Stock.

     If the Conversion Value of the Notes shall be based on Reference Property as set forth above,
the Company’s obligation to deliver the consideration described in Section 10.01 with respect to
each $1,000 principal amount of Notes tendered for conversion after the effective date of any such
Disposition Event, shall, notwithstanding anything to the contrary set forth in Section 10.01, be
settled in Cash and units of Reference Property (if applicable) and the Company shall deliver, as
promptly as practicable immediately following the last Trading Day of the Conversion Reference
Period:

49

 

	 	(1)	 	Cash in an amount equal to the lesser of (A) $1,000 and (B) the
Conversion Value, and
	 
	 	(2)	 	if the Conversion Value is greater than $1,000, (a) Cash equal
to the difference between the aggregate Conversion Value and $1,000, (b) an
amount in Reference Property, determined as set forth in Section 10.01(b), with
a fair market value, as determined by the Conversion Agent, equal to the
Conversion Value less $1,000 or (c) a combination thereof, at the Company’s
election, determined as set forth in Section 10.01(b); and
	 
	 	(3)	 	an amount in Cash in lieu of any fractional shares of Common
Stock calculated based on the Average Price,

provided that, in each case, (x) the Conversion Value and the Daily Share
Amounts, shall be determined as if the words “Volume Weighted Average Price per
share of Common Stock” in the definition of each such term were replaced by the
words “Volume Weighted Average Price per unit of Reference Property composed of the
kind and amount of Cash, securities or other property that a holder of one share of
Common Stock immediately prior to such Disposition Event would have owned or been
entitled to receive”, (y) the Volume Weighted Average Price shall be determined with
respect to such a unit of Reference Property and (z) references to “Remaining
Shares” and “shares of Common Stock” were instead references to “a unit of Reference
Property composed of the kind and amount of Cash, securities or other property that
a holder of one share of Common Stock immediately prior to such Disposition Event
would have owned or been entitled to receive.”

          Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent
as may be practicable to the adjustments provided for in this Article 10. If, in the case of any
such Disposition Event, the stock or other securities and assets receivable thereupon by a holder
of Common Stock includes shares of stock or other securities and assets of a Person other than the
successor or purchasing Person, as the case may be, in such Disposition Event, then such
supplemental indenture shall also be executed by such other Person and shall contain such
additional provisions to protect the interests of the Noteholders as the Board of Directors shall
reasonably consider necessary by reason of the foregoing.

          The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each Noteholder, at the address of such Noteholder as it appears on the register of the Notes
maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.

          The above provisions of this Section 10.12 shall similarly apply to successive Disposition
Events.

If this Section 10.12 applies to any event or occurrence, none of Section 10.06, Section 10.07,
Section 10.08, Section 10.09 or Section 10.10 shall apply.

     Section 10.13 Adjustment to Conversion Rate Upon Change in Control Transactions,
Discretionary Adjustment.

     (a) If, after the Issue Date, a Change in Control occurs and a Holder elects to convert
its Notes in connection with such Change in Control, the Company will increase the
Conversion Rate for the Notes surrendered for conversion by a number of additional shares of
Common Stock (the “Make-Whole Shares”), as described in this Section 10.13. A conversion of
Notes will be deemed for the purposes of this Section 10.13 to be “in connection with” a
Change in Control transaction if the notice of conversion of the Notes is received by the
Conversion Agent from and including the effective date of the Change in Control transaction
up to and including the Trading Day prior to the related Change in Control Purchase Date.

     (b) The number of Make-Whole Shares will be determined by reference to the table below
and is based on the date which such Change in Control transaction becomes effective (the
“Change in Control Effective Date”) and the price paid per share of Common Stock in the
Change in Control (in the case of a change in control described in clause (ii) of the
definition thereof), or in the case of all other Changes in Control, the average of the
Closing Prices per share of Common Stock over the five Trading-Day period ending on the
Trading Day preceding the relevant Change in Control Effective Date (the “Stock Price”). If
holders of Common Stock receive only cash in the case of a Change in Control described in
clause (ii) of the definition thereof, the Stock Price shall be the Cash amount paid per
share of Common Stock. Otherwise, the Stock Price shall be the average of the Closing Prices
per share of Common Stock over the five Trading-Day period ending on the Trading Day
preceding the relevant Change in Control Effective Date.

     (c) The Stock Prices set forth in the first row of the table below will be adjusted as
of any date on which the Conversion Rate is adjusted. The adjusted Stock Prices will equal
the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction,
the numerator of which is the Conversion Rate immediately prior to the adjustment giving
rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so
adjusted. In addition, the number of Make-Whole Shares on the table below will be subject
to adjustment in the same manner as the Conversion Rate as set forth in Section 10.06
through Section 10.10.

     (d) If the exact Stock Prices and Change in Control Effective Dates are not set
forth in the table, then: (i) if the Stock Price is between two Stock Prices in the table
or the Change in Control Effective Date is between two Change in Control Effective Dates in
the table, the Make-Whole Shares issued upon conversion of the Notes will be determined by a
straight-line interpolation between the number of Make-Whole Shares set forth for the higher
and lower Stock Prices and the earlier and later Change in Control Effective Dates in the
table, based on a 365-day year, (ii) if the Stock Price is in excess of $32.00 per share,
subject to adjustment as set forth in Section 10.13(c), no Make-Whole Shares will be issued
upon conversion of the Notes; and (iii) if the Stock Price is less than $15.61 per share,
subject to adjustment as set forth in Section 10.13(c), no Make-Whole Shares will be issued
upon conversion of the Notes.

     (e) The Company may make such increases in the Conversion Rate, in addition to those
required by Sections 10.06, 10.07, 10.08, 10.09 and 10.10 as the Board of Directors
considers to be advisable to avoid or diminish any income tax to holders of Common Stock or
rights to purchase Common Stock resulting from any dividend or distribution of stock (or
rights to acquire stock) or from any event treated as such for income tax purposes.

     (f) To the extent permitted by applicable law, the Company from time to time may
increase the Conversion Rate by any amount for any period of time if the period is at least
twenty (20) days, the increase is irrevocable during the period and the Board of Directors
shall have made a determination that such increase would be in the best interests of the
Company, which determination shall be conclusive. Whenever the Conversion Rate is increased
pursuant to the preceding sentence, the Company shall mail to holders of record of the Notes
a notice of the increase at least fifteen (15) 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.

     Section 10.14 When Adjustment May Be Deferred. No adjustment in the Conversion Rate
need be made unless the adjustment would require an increase or decrease of at least 1% of the
Conversion Rate. Any adjustments that are less than 1% of the Conversion Rate shall be carried
forward and taken into account in determining any subsequent adjustment. In addition, the Company
shall make any carry forward adjustments not otherwise effected upon required purchase of the notes
pursuant to Section 3.01, and on April 5, 2011.

     Section 10.15 When No Adjustment Required.

     (a) No adjustment need be made for a transaction referred to in Section 10.06, Section
10.07, Section 10.08, Section 10.09 or Section 10.10 if Noteholders participate, without
conversion, in the transaction or event that would otherwise give rise to an adjustment
pursuant to such Section at the same time as holders of the Common Stock participate with
respect to such transaction or event and on the same terms as holders of the Common Stock
participate with respect to such transaction or event as if Noteholders, at such time, held
a number of shares of Common Stock equal to the Conversion Rate at such time.

52

 

     (b) No adjustment need be made for the issuance of Common Stock or any securities
convertible into or exchangeable for Common Stock or carrying the right to purchase Common
Stock or any such security.

     (c) No adjustment need be made for rights to purchase Common Stock pursuant to a
Company plan for reinvestment of dividends or interest.

     (d) No adjustment need be made for a change in the par value or no par value of the
Common Stock.

     (e) To the extent the Notes become convertible pursuant to this Article 10 into Cash,
no adjustment need be made thereafter as to the Cash. Interest will not accrue on the Cash.

     (f) The Conversion Rate shall not exceed 64.0615 shares per $1,000 principal amount of
the Notes on account of adjustments to the Conversion Rate pursuant to this Article 10,
subject to the adjustments set forth in Sections 10.06, 10.07, 10.08, 10.09 and 10.10 above.
Further, notwithstanding anything in this Article 10 (subject only to the provisions of the
second succeeding sentence), the conversion rate shall not exceed 103.4974 per $1,000
principal amount of the Notes (provided that if and to the extent that the Initial
Purchasers’ option to purchase additional Notes or additional 2013 Notes is exercised, the
maximum conversion rate shall be ratably decreased, such that in the case of a full exercise
by the Initial Purchasers of their option to purchase the Notes and the 2013 Notes, the
conversion rate shall not exceed 94.0886 per $1,000 principal amount of the Notes, other
than as a result of adjustments to the Conversion Rate in the manner set forth in Sections
10.06, 10.07 and 10.08 (such limitations herein referred to as the “Conversion Rate Cap”).
The Company shall not take any action if, as a result of such action, the adjustment to the
Conversion Rate that would otherwise be made pursuant to the provisions of 10.09 or 10.10 would be limited by the Conversion Rate Cap, unless
such action would not result in a violation of NASD Rule 4350 as such rule or successor to
such rule may be then in effect and interpreted by the NASD. If such action would not
result in a violation of NASD Rule 4350, then the Conversion Rate Cap shall not apply to
such action taken by the Company.

     Section 10.16 Notice of Adjustment. Whenever the Conversion Rate is adjusted, the
Company shall promptly mail to Noteholders a notice of the adjustment. The Company shall file with
the Trustee and the Conversion Agent such notice and a certificate from the Company’s independent
public accountants briefly stating the facts requiring the adjustment and the manner of computing
it. The certificate shall be conclusive evidence that the adjustment is correct. Neither the
Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such
certificate except to exhibit the same to any Holder desiring inspection thereof.

     Section 10.17 Notice of Certain Transactions. If (a) the Company takes any action
that would require an adjustment in the Conversion Rate pursuant to Section 10.06, 10.07, 10.08,
10.09 or 10.10 (unless no adjustment is to occur pursuant to Section 10.14 or Section 10.15), (b)
the Company takes any action that would require a supplemental indenture pursuant to Section

53

 

10.12,
or (c) there is a liquidation or dissolution of the Company, then the Company shall mail to
Noteholders and file with the Trustee and the Conversion Agent a notice stating the proposed
Ex-Dividend Date for a dividend or distribution or the proposed effective date of a subdivision,
combination, reclassification, consolidation, merger, binding share exchange, transfer, liquidation
or dissolution. The Company shall file and mail the notice at least 15 days before such date;
provided that if the Company elects to make a distribution described in Section 10.07, Section
10.08, or Section 10.09, and in the case of Section 10.08 or Section 10.09, that has a per share
value equal to more than 10% of the Closing Price per share of Common Stock on the day preceding
the declaration date for such distribution, the Company shall give notice to Holders at least 20
Trading Days prior to the Ex-dividend Date for such distribution. Failure to file or mail the
notice or any defect in it shall not affect the validity of the transaction.

     Section 10.18 Right of Holders to Convert. Notwithstanding any other provision in
this Indenture, the Holder of any Note shall have the right to convert its Note in accordance with
this Article 10 and paragraph 7 of the Notes and to bring an action for the enforcement of any such
right to convert, and such rights shall not be impaired or affected without the consent of such
Holder.

     Section 10.19 Company Determination Final. The Company shall be responsible for
making all calculations called for hereunder and under the Notes. These calculations include, but
are not limited to, Conversion Value, the Conversion Date, the Volume Weighted Average Price, the
Conversion Reference Period, the Closing Price, the Conversion Price, the Required Cash Amount, the
Applicable Conversion Rate and the number of shares of Common Stock, if any, to be issued upon
conversion of the Notes. The Company shall make all these calculations in good faith and, absent manifest
error, the Company’s calculations will be final and binding on Noteholders. The Company shall
provide a schedule of the Company’s calculations to the Trustee, and the Trustee is entitled to
rely upon the accuracy of the Company’s calculations without independent verification.

     Section 10.20 Trustee’s Adjustment Disclaimer. The Trustee has no duty to determine
when an adjustment under this Article 10 should be made, how it should be made or what it should
be. The Trustee has no duty to determine whether a supplemental indenture under Section 10.12 need
be entered into or whether any provisions of any supplemental indenture are correct. The Trustee
shall not be accountable for and makes no representation as to the validity or value of any
securities or assets issued upon conversion of Notes. The Trustee shall not be responsible for the
Company’s failure to comply with this Article 10. Each Conversion Agent shall have the same
protection under this Section 10.20 as the Trustee.

     Section 10.21 Simultaneous Adjustments.

     (a) For purposes of Section 10.08, Section 10.06(a) and Section 10.07, any dividend or
distribution to which Section 10.08 is applicable that also includes shares of Common Stock,
or rights, options or warrants to subscribe for or purchase shares of Common Stock (or
both), shall be deemed instead to be (1) a dividend or distribution of the debt securities,
assets or shares of Capital Stock other than such shares of Common Stock or rights (and any
Conversion Rate adjustment required by Section 10.08 with respect to such dividend or
distribution shall then be made) immediately followed by (2)

54

 

a dividend or distribution of
such shares of Common Stock or such rights (and any further Conversion Rate adjustment
required by Section 10.06(a) and Section 10.07 with respect to such dividend or distribution
shall then be made), except any shares of Common Stock included in such dividend or
distribution shall not be deemed “outstanding at the close of business on the Business Day
immediately preceding such Ex-Dividend Date” within the meaning of Section 10.06(a).

     (b) The reclassification of the Common Stock into securities including securities other
than Common Stock (other than any reclassification upon an event to which Section 10.12
applies) shall be deemed to involve (a) a distribution of such securities other than the
Common Stock to all holders of Common Stock (and the effective date of such reclassification
shall be deemed to be the “Ex-Dividend Date” within the meaning of this Section 10.08), and
(b) a subdivision or combination, as the case may be, of the number of shares of Common
Stock outstanding immediately prior to such reclassification into the number of shares of
Common Stock outstanding immediately thereafter (and the effective date of such
reclassification shall be deemed to be “the day upon which such subdivision becomes
effective” or “the day upon which such combination becomes effective”, as the case may be,
and “the day upon which such subdivision or combination becomes effective” within the
meaning of Section 10.06(b)).

     Section 10.22 Successive Adjustments. After an adjustment to the Conversion Rate under this Article 10, any subsequent event
requiring an adjustment under this Article 10 shall cause an adjustment to the Conversion Rate as
so adjusted.

     Section 10.23 Rights Issued in Respect of Common Stock Issued Upon Conversion. Each
share of Common Stock issued upon conversion of Notes pursuant to this Article 10 shall be entitled
to receive the appropriate number of rights (“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 the Rights Agreement, dated as of August 12, 1998, between the Company
and BankBoston, N.A., as Rights Agent, or any successor shareholder rights agreement adopted by the
Company, as the same may be amended form time to time (in each case, a “Shareholders Rights Plan”).
If the Shareholders Rights Plan under which any Rights are issued provides that each share of
Common Stock issued upon conversion of the Notes at any time prior to the distribution of separate
certificates representing such Rights will be entitled to receive such Rights, there shall not be
any adjustment to the conversion privilege or Conversion Rate at any time prior to the distribution
of separate certificates representing such Rights. If, however, prior to any conversion the Rights
have separated from the Common Stock, the Conversion Rate shall be adjusted at the time of
separation as if the Company distributed to all Holders of the Common Stock, its assets, debt

ARTICLE 11

PAYMENT OF INTEREST

     Section 11.01 Interest Payments. Interest on any Note that is payable, and is
punctually paid or duly provided for, on any applicable Interest Payment Date shall be paid to the
person in whose name that Note is registered at the Close of Business on the Regular Record Date
for such interest at the office or agency of the Company maintained for such purpose. Each
installment of interest payable in Cash on any Note shall be paid in same-day funds by transfer to
an account maintained by the payee located inside the United States, if the Trustee shall have
received proper wire transfer instructions from such payee not later than the related Regular
Record Date or, if no such instructions have been received by check drawn on a bank in the United
States mailed to the payee at its address set forth on the Registrar’s books. In the case of a
Global Note, interest payable on any applicable payment date will be paid by wire transfer of
same-day funds to the Depositary, with respect to that portion of such Global Note held for its account by Cede &
Co. for the purpose of permitting such party to credit the interest received by it in respect of
such Global Note to the accounts of the beneficial owners thereof.

     Section 11.02 Defaulted Interest. Except as otherwise specified with respect to the
Note, any interest on any Note that is payable, but is not punctually paid or duly provided for,
within 30 days following any applicable payment date (herein called “Defaulted Interest”, which
term shall include any accrued and unpaid interest that has accrued on such defaulted amount in
accordance with paragraph 1 of the Notes), shall forthwith cease to be payable to the registered
Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause
(a) or (b) below.

     (a) The Company may elect to make payment of any Defaulted Interest to the persons in
whose names the Notes are registered at the Close of Business on a Special Record Date for
the payment of such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to
be paid on each Note and the date of the proposed payment (which shall not be less than 20
days after such notice is received by the Trustee), and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit on or prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the persons entitled to such Defaulted
Interest as in this clause provided. Thereupon the Trustee shall fix a special record date
for the payment of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment (the “Special Record Date”).
The Trustee shall promptly notify the Company of such Special Record Date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and

56

 

the Special Record Date therefor to be mailed, first-class postage
prepaid, to each Holder of Notes at his address as it appears on the list of Noteholders
maintained pursuant to Section 2.05 not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the
persons in whose names the Notes are registered at the Close of Business on such Special
Record Date and shall no longer be payable pursuant to the following clause (b).

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

     Section 11.03 Interest Rights Preserved. Subject to the foregoing provisions of this Article 11 and Section 2.06, each Note
delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of
any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were
carried by such other Notes.

Notes, but only if the Trustee receives the notice of revocation before the date the

by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the
extent permitted by applicable law, in the event of any inconsistency between the terms of this
Note and the terms of the Indenture, the terms of the Indenture will control.

     The Notes are general unsecured obligations of the Company.

6. Repurchase at the Option of the Holder upon a Change in Control.

     At the option of the Holder and subject to the terms and conditions of the Indenture, the
Company shall become obligated to purchase the Notes held by such Holder on the date, at the
purchase price and as otherwise provided in the Indenture.

     Holders have the right to withdraw any Change in Control Purchase Notice by delivering to the
Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

Paying Agent, and the Holder thereof shall have no other rights as such (other than the right to
receive the Change in Control Purchase Price and accrued and unpaid interest upon surrender of such
Notes).

7. Conversion.

     A Holder of a Note may convert such Note into Cash and, to the extent the Conversion Value of
such Note is greater than $1,000, Cash, shares of Common Stock or a combination thereof, at the
option of the Company, as described in the Indenture before the Close of Business on the Business
Day immediately preceding Maturity Date, if at least one of the following conditions is satisfied:

     (a) during any calendar quarter commencing at any time after June 30, 2006, and only during
such calendar quarter, if the Closing Price of the Common Stock for at least 20 Trading Days in the
period of 30 consecutive Trading Days ending on the last Trading Day of the preceding calendar
quarter exceeds 130% of the Conversion Price per share of Common Stock on the last day of such
preceding calendar quarter (the “Conversion Trigger Price”);

     (b) during the five Business Day period immediately after any five consecutive Trading Day
period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes
for each day of such Measurement Period was less than 98% of the product of the Closing Price of
the Common Stock on such date and the Conversion Rate on such date;

     (c) the Company elects to distribute to all holders of Common Stock (i) rights or warrants
entitling all holders of the Common Stock to subscribe for or purchase, for a period expiring
within 60 days after the record date for such distribution, Common Stock at less than the average
of the Closing Prices of the Common Stock for the five consecutive Trading Days ending on the date
immediately preceding the first public announcement of the distribution, or (ii) Cash, debt
securities (or other evidence of Debt) or other assets (excluding dividends or distributions
described in Section 10.06 of the Indenture), which distribution, together with all other
distributions within the preceding twelve months, has a per share value exceeding 10% of the
average of the Closing Prices of the Common Stock for the five consecutive Trading Days ending on
the date immediately preceding the first public announcement of the distribution; or

     (d) if a Change of Control occurs or if the Company is a party to a consolidation, merger,
binding share exchange or transfer or lease of all or substantially all of the Company’s assets,
pursuant to which the Common Stock would be converted into Cash, securities or other assets; or

     (e) at any time on or after April 5, 2011 until the Close of Business on the Business Day
immediately preceding the Maturity Date.

     The Conversion Agent will determine on the Company’s behalf at the beginning of each calendar
quarter commencing at any time after June 30, 2006 through the calendar quarter ending March 31,
2011 whether the Notes are convertible as a result of the price of the

6

 

Common Stock pursuant to clause (a) above and will notify the Company and the Trustee if the
Notes are so convertible.

     The Trustee shall have no obligation to determine the Trading Price of the Notes pursuant to
clause (b) above unless the Company has requested such determination; and the Company shall have no
obligation to make such request unless a Holder provides the Company with reasonable evidence that
the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the
Closing Price and the Conversion Rate. At such time, the Company shall instruct the Trustee to
determine the Trading Price beginning on the next Trading Day and on each successive Trading Day
until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the
product of the Closing Price and the Conversion Rate.

     If the Company makes a distribution described in subsection (c)(i) or (c)(ii), the Company
must notify Holders at least 20 Trading Days prior to the Ex-Dividend Date for such distribution.
Once the Company has given such notice, Holders may surrender their Notes for conversion at any
time until the earlier of the Close of Business on the Business Day prior to the Ex-Dividend Date
for such distribution or the Company’s announcement that such distribution will not take place,
even if the Notes are not convertible at that time.

     The Company will notify Noteholders and the Trustee as promptly as practicable following the
date on which the Company publicly announces any transaction described in clause (d) above, but in
no event less than 20 Trading Days prior to the anticipated effective date of such transaction.
Noteholders may surrender their Notes for conversion at any time after the date that is 15 Trading
Days prior to the anticipated effective date of such transaction until 35 Trading Days after the
actual date of such transaction (or, if such transaction also constitutes a Change in Control,
until the Change in Control Purchase date).

8. Defaults and Remedies.

     If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the Notes may declare all the Notes to be due
and payable, subject to certain limitations set forth in the Indenture. If a bankruptcy or
insolvency default with respect to the Company occurs and is continuing, the Notes automatically
become due and payable. Holders may not enforce the Indenture or the Notes except as provided in
the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount
of the Notes then outstanding may direct the Trustee in its exercise of remedies.

9. Amendment and Waiver.

     Subject to certain exceptions set forth in the Indenture, the Indenture and the Notes may be
amended, or default may be waived, with the consent of the Holders of a majority in principal
amount of the outstanding Notes. Without notice to or the consent of any Holder, the Company and
the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any
ambiguity, defect or inconsistency or if such amendment or supplement does not adversely affect the
interests of the Holders in any material respect.

7

 

10. Registered Form; Denominations; Transfer; Exchange.

     The Notes are in registered form without coupons in denominations of $1,000 principal amount
and integral multiples of $1,000. A Holder may register the transfer or exchange of Notes in
accordance with the Indenture. The Trustee may require a Holder to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. Pursuant to the Indenture, there are certain periods during which the Trustee will
not be required to issue, register the transfer of or exchange any Note or certain portions of a
Note.

11. Persons Deemed Owners.

     The registered Holder of this Note may be treated as the owner of this Note for all purposes.

12. Unclaimed Money or Notes.

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

13. Trustee Dealings with the Company.

waiver and release are part of the consideration for the issue of the Notes.

          A Note shall not be valid until an authorized signatory of the Trustee manually signs the
certificate of authentication on the Note. The signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

          The Trustee shall authenticate and make available for delivery Notes for original issue in the
aggregate principal amount of $1,000,000,000 (or up to $1,100,000,000 to the extent the Initial
Purchasers exercise their over-allotment option) upon receipt of a written order or orders of the
Company signed by an Officer of the Company (a “Company Order”). The Company Order shall specify
the amount of Notes to be authenticated, shall provide that all such Notes will be represented by a
Global Note and the date on which each original issue of Notes is to be authenticated. The initial
aggregate principal amount of Notes outstanding at any time may not exceed $1,000,000,000 (or
$1,100,000,000 to the extent the Initial Purchasers exercise their over-allotment option) except as
provided in Section 2.07 and except as provided in the next succeeding paragraph.

          The Company may, without the consent of any holders of Notes, reopen the Notes and issue
additional Notes hereunder with the same terms and with the same CUSIP number as the Notes
initially issued hereunder in an unlimited aggregate principal amount, which will form the same
series with the Notes initially issued hereunder so long as such additional Notes are fungible with
the Notes initially issued hereunder for U.S. federal income tax purposes.

          The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may
appoint an authenticating agent acceptable to the Company to authenticate Notes. An

11

 

authenticating
agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An authenticating agent shall
have the same rights as an Agent to deal with the Company or an Affiliate of the Company.

          The Notes shall be issuable only in registered form without coupons and only in denominations
of $1,000 principal amount and any integral multiple thereof.

     Section 2.03 Registrar, Paying Agent and Conversion Agent. The Company shall maintain
one or more offices or agencies where Notes may be presented for registration of transfer or for
exchange (each, a “Registrar”), one or more offices or agencies where Notes may be presented for
payment (each, a “Paying Agent”), one or more offices or agencies where Notes may be presented for
conversion (each, a “Conversion Agent”) and one or more offices or agencies where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be served. The
Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an office or
agency where notices and demands to or upon the Company in respect of the Notes and this Indenture
may be served in the United States. One of the Registrars (the “Primary Registrar”) shall keep a
register of the Notes and of their transfer and exchange (the “Register”).

          The Company shall enter into an appropriate agency agreement with any Agent not a party to
this Indenture. 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 Agent not a party to
this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or
agent for service of notices and demands in any place required by this Indenture, or fails to give
the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company
may act as Paying Agent (except for the purposes of Article 8).

          The Company hereby initially designates the Trustee as Paying Agent, Registrar, and Conversion
Agent, and the Corporate Trust Office of the Trustee as such office or agency of the Company for
each of the aforesaid purposes.

     Section 2.04 Paying Agent To Hold Money In Trust. Prior to 11:00 a.m., New York City
time, on each date on which the principal amount of or interest, if any, on any Notes is due and
payable, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal
amount or interest, if any, so becoming due. A Paying Agent shall hold in trust for the benefit of
Noteholders or the Trustee all money held by the Paying Agent for the payment of principal amount
of or interest, if any, on the Notes, and shall notify the Trustee of any default by the Company
(or any other obligor on the Notes) in making any such payment. If the Company or an Affiliate of
the Company acts as Paying Agent, it shall, before 11:00 a.m., New York City time, on each date on
which a payment of the principal amount of or interest on any Notes is due and payable, segregate
the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent
to pay all money
held by it to the Trustee, and the Trustee may at any time during the continuance of any
default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the
Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other
than the Company) shall have no further liability for the money.

12

 

     Section 2.05 Noteholder 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
Noteholders. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee
on or before each semiannual 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 Noteholders.

     Section 2.06 Transfer and Exchange. Subject to compliance with any applicable
additional requirements contained in Section 2.14, when a Note is presented to a Registrar with a
request to register a transfer thereof or to exchange such Note for an equal principal amount of
Notes of other authorized denominations, the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met; provided, however, that
every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed
or accompanied by an assignment form in the form included in Exhibit A, and in form satisfactory to
the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. To
permit registration of transfers and exchanges, upon surrender of any Note for registration of
transfer or exchange at an office or agency maintained pursuant to Section 2.03, the Company shall
execute and the Trustee shall authenticate Notes of a like aggregate principal amount at the
Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or
the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto, and provided, that this sentence shall not apply to any
exchange pursuant to Section 2.10, Section 3.04, Section 9.03(b) or Section 10.02(g) not involving
any transfer.

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

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

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

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

13

 

     Section 2.07 Replacement Notes. If any mutilated Note is surrendered to the Company,
a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company,
the applicable Registrar and the Trustee such security or indemnity as will be required by them to
save each of them harmless, then, in the absence of notice to the Company, such Registrar or the
Trustee that such Note has been acquired by a protected purchaser, the Company shall execute, and
upon its written request the Trustee shall authenticate and deliver, in exchange for any such
mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and
principal amount, 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, or is about to be purchased by the Company pursuant to Article 3, the Company in
its discretion may, instead of issuing a new Note, pay or purchase such Note, as the case may be.

          Upon the issuance of any new Notes under this Section 2.07, 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 reasonable expenses (including the reasonable fees and expenses of
the Trustee or the Registrar) in connection therewith.

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

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

     Section 2.08 Outstanding Notes. Notes outstanding at any time are all Notes
authenticated by the Trustee, except for those canceled by it, those converted pursuant to Article
10, those delivered to it for cancellation or surrendered for transfer or exchange and those
described in this Section 2.08 as not outstanding.

          If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Company
receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

          If a Paying Agent holds at 11:00 a.m., New York City time, on the Maturity Date Cash
sufficient to pay the principal amount of the Notes payable on that date, then on and after the
Maturity Date, such Notes shall cease to be outstanding and the principal amount thereof shall
cease to bear interest.

          Subject to the restrictions contained in Section 2.09, a Note does not cease to be outstanding
because the Company or an Affiliate of the Company holds the Note.

14

 

     Section 2.09 Treasury Notes. (a) In determining whether the Holders of the required
principal amount of Notes have concurred in any notice, direction, waiver or consent, Notes owned
by the Company or any other obligor on the Notes or by any Affiliate of the Company or of such
other obligor shall be disregarded, except that, for purposes of determining whether the Trustee
shall be protected in relying on any such notice, direction, waiver or consent, only Notes which a
Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned
which have been pledged in good faith shall not be disregarded if the pledgee establishes to the
satisfaction of the Trustee the pledgee’s right so to act with respect to the Notes and that the
pledgee is not the Company or any other obligor on the Notes or any Affiliate of the Company or of
such other obligor. Any Notes or shares of Common Stock issued upon the conversion of Notes that
are purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or
such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from
the registration requirements of the Securities Act in a transaction that results in such Notes or
shares of Common Stock, as the case may be, no longer being “restricted securities” (as defined
under Rule 144).

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

     Section 2.11 Cancellation. The Company at any time may deliver Notes to the Trustee
for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the
Trustee or its agent any Notes surrendered to them for transfer, exchange, payment or conversion.
The Trustee and no one else shall cancel, in accordance with its standard procedures, all Notes
surrendered for transfer, exchange, payment, conversion or cancellation and upon written request of
the Company shall deliver the canceled Notes to the Company.

     Section 2.12 CUSIP Numbers. The Company in issuing the Notes may use one or more
“CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in
notices of purchase as a convenience to Holders; provided, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Notes or as
contained in any notice of a purchase and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such purchase shall not be affected by any
defect in or omission of such numbers. The Company will promptly notify the Trustee of any change
in the “CUSIP” numbers.

     Section 2.13 Book-entry Provisions For Global Notes.

     (a) Transfers of Global Notes shall be limited to transfers in whole, but not in part,
to the Depositary, its successors or their respective nominees. In addition, Certificated
Notes shall be transferred to all beneficial owners, as identified by the Depositary, in
exchange for their beneficial interests in Global Notes only if (i) the Depositary notifies
the Company that the Depositary is unwilling or unable to continue as

15

 

depositary for any
Global Note (or the Depositary ceases to be a “clearing agency” registered under Section 17A
of the Exchange Act) and a successor Depositary is not appointed by the Company within
ninety (90) days of such notice or cessation or (ii) an Event of Default has occurred and is
continuing and the Registrar has received a written request from the Depositary to issue
Certificated Notes.

     (b) In connection with the transfer of a Global Note in its entirety to beneficial
owners pursuant to Section 2.13(a), such Global Note shall be deemed to be surrendered to
the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon
written instructions from the Company authenticate and deliver, to each beneficial owner
identified by the Depositary in exchange for its beneficial interest in such Global Note, an
equal aggregate principal amount of Certificated Notes of authorized denominations.

     (c) Any Certificated Note constituting a Restricted Certificated Note delivered in
exchange for an interest in a Global Note pursuant to Section 2.13(a) shall, except as
otherwise provided by Section 2.14, bear the Restricted Note Legend.

     (d) The Holder of any Global Note may grant proxies and otherwise authorize any Person
to take any action that a Holder is entitled to take under this Indenture or the Notes.

     Section 2.14 Special Transfer Provisions.

     (a) Notwithstanding any other provisions of this Indenture, but except as provided in
Section 2.14(b), a Global Note may not be transferred except as a whole by the Depositary to
a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary.

     (b) Every Note that bears or is required under this Section 2.14(b) to bear the
Restricted Note Legend, and any Common Stock that bears or is required under this Section
2.14(b) to bear the Restricted Common Stock Legend (collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in the Restricted
Note Legend or the Restricted Common Stock Legend, as the case may be, unless such
restrictions on transfer shall be waived by written consent of the Company, and the holder
of each such Restricted Security, by such Notes holder’s acceptance thereof, agrees to be
bound by all such restrictions on transfer. As used in this Section 2.14(b), the term
“transfer” encompasses any sale, pledge, loan, transfer or other disposition whatsoever of
any Restricted Security or any interest therein.

          Until the Resale Restriction Termination Date, any certificate evidencing such Note (and all
securities issued in exchange therefor or substitution thereof), and any stock certificate
representing shares of Common Stock issued upon conversion of any Note, shall bear a Restricted
Note Legend or a Restricted Common Stock Legend, as the case may be, unless such Note or such
shares of Common Stock have been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at

16

 

the time of such
transfer) or pursuant to Rule 144 or any similar provision then in force, or such shares of Common
Stock have been issued upon conversion of Notes that have been transferred pursuant to a
registration statement that has been declared effective under the Securities Act or pursuant to
Rule 144 under the Securities Act, or unless otherwise agreed by the Company in writing, with
written notice thereof to the Trustee.

          Any Note (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms or as to conditions for
removal of the Restricted Note Legend set forth therein have been satisfied may, upon surrender of
such Note for exchange to the Registrar in accordance with the provisions of Section 2.06, be
exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not
bear the Restricted Note Legend. If the Restricted Note surrendered for exchange is represented by
a Global Note bearing the Restricted Note Legend, the principal amount of the legended Global Note
shall be reduced by the appropriate principal amount and the principal amount of a Global Note
without the Restricted Note Legend shall be increased by an equal principal amount. If a Global
Note without the Restricted Note Legend is not then outstanding, the Company shall execute and the
Trustee shall authenticate and deliver an unlegended Global Note to the Depositary.

          Any such shares of Common Stock as to which such restrictions on transfer shall have expired
in accordance with their terms or as to which the conditions for removal of the Restricted Common
Stock Legend set forth therein have been satisfied may, upon surrender of the certificates
representing such shares of Common Stock for exchange in accordance with the procedures of the
transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like
number of shares of Common Stock, which shall not bear the Restricted Common Stock Legend required
by this Section 2.14.

     (c) By its acceptance of any Note bearing the Restricted Note Legend, each Holder of
such a Note acknowledges the restrictions on transfer of such Note set forth in
this Indenture and in the Restricted Note Legend and agrees that it will transfer such
Note only as provided in this Indenture and as permitted by applicable law.

     (d) The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.13 or this Section 2.14. The Company shall
have the right to inspect and make copies of all such letters, notices or other written
communications at any reasonable time during normal hours of operation of the Registrar upon
the giving of reasonable notice to the Registrar.

ARTICLE 3

PURCHASES

     Section 3.01 Repurchase At the Option of the Holder.

     (a) If there shall have occurred a Change in Control, each Holder shall have the right,
at such Holder’s option, to require the Company to purchase for Cash all or any portion of
such Holder’s Notes in integral multiples of $1,000 principal amount on a date

17

 

selected by
the Company (the “Change in Control Purchase Date”), which Change in Control Purchase Date
shall be no later than thirty-five (35) Trading Days after the occurrence of such Change in
Control, at a purchase price equal to 100% of the principal amount of the Notes to be
purchased, plus accrued and unpaid interest to, but excluding, the Change in Control
Purchase Date (the “Change in Control Purchase Price”), subject to satisfaction by or on
behalf of the Holder of the requirements set forth in Section 3.01(c); provided that if the
Change in Control Purchase Date is after a Regular Record Date and on or prior to the
Interest Payment Date to which it relates, interest accrued to the Interest Payment Date
will be paid to Holders of the Notes as of the preceding Regular Record Date.

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

               (i) any person or group, other than the Company, its Subsidiaries or any
employee benefits plan of the Company or its Subsidiaries, files a Schedule 13D or
Schedule TO (or any successor schedule, form or report) pursuant to the Exchange
Act, disclosing that such person has become the beneficial owner of shares with a
majority of the total voting power of the Company’s outstanding Voting Securities;
unless such beneficial ownership arises solely as a result of a revocable proxy
delivered in response to a proxy or consent solicitation made pursuant to the
applicable rules and regulations under the Exchange Act; or

               (ii) the Company consolidates with or merges with or into another person (other
than a Subsidiary of the Company), or sells, conveys, transfers or leases all or
substantially all of its properties and assets to any person (other than a
Subsidiary of the Company) or any person (other than a Subsidiary of the Company)
consolidates with or merges with or into the Company, and the outstanding Voting
Securities of the Company are reclassified into, converted for
or converted into the right to receive any other property or security, provided
that none of these circumstances will be a Change in Control if persons that
beneficially own the Voting Securities of the Company immediately prior to the
transaction own, directly or indirectly, shares with a majority of the total voting
power of all outstanding Voting Securities of the surviving or transferee person
immediately after the transaction in substantially the same proportion as their
ownership of the Company’s Voting Securities immediately prior to the transaction.

          For purposes of defining a Change in Control:

	 	(x)	 	the term “person” and the term “group” have the meanings given
by Section 13(d) and 14(d) of the Exchange Act or any successor provisions;
	 
	 	(y)	 	the term “group” includes any group acting for the purpose of
acquiring, holding or disposing of securities within the meaning of Rule
13d-5(b)(1) under the Exchange Act or any successor provision; and

18

 

	 	(z)	 	the term “beneficial owner” is determined in accordance with
Rules 13d-3 and 13d-5 under the Exchange Act or any successor provisions,
except that a person will be deemed to have beneficial ownership of all shares
that person has the right to acquire irrespective of whether that right is
exercisable immediately or only after the passage of time.

          Notwithstanding the foregoing, it will not constitute a Change in Control if at least 90% of
the consideration for the Common Stock (excluding Cash payments for fractional shares and Cash
payments made in respect of dissenter’s appraisal rights and Cash payment of the Required Cash
Amount, if any) in the transaction or transactions constituting the Change in Control consists of
common stock traded on a United States national securities exchange or quoted on The Nasdaq
National Market, or which will be so traded or quoted when issued or exchanged in connection with
the Change in Control, and as a result of such transaction or transactions the Notes become
convertible solely into such common stock.

     (b) As promptly as practicable following the date the Company publicly announces the
Change in Control transaction, but in no event less than 20 Trading Days prior to the
anticipated effective date of a Change in Control, the Company shall mail a written notice
of Change in Control by first-class mail to the Trustee and to each Holder at their
addresses shown in the register of the Registrar (and to beneficial owners as required by
applicable law). The notice shall include a form of Change in Control Purchase Notice to be
completed by the Noteholder and shall state:

     (i) briefly, the events causing a Change in Control;

     (ii) the anticipated effective date of such Change in Control;

     (iii) the date by which the Change in Control Purchase Notice pursuant to this
Section 3.01 must be given;

     (iv) the Change in Control Purchase Price;

     (v) the Change in Control Purchase Date;

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

     (vii) the then-current Conversion Rate and any adjustments thereto;

     (viii) that Notes with respect to which a Change in Control Purchase Notice has
been given by the Holder may be converted pursuant to Article 10 hereof only if the
Change in Control Purchase Notice has been withdrawn in accordance with the terms of
this Indenture;

     (ix) briefly, the procedures a Holder must follow to exercise rights under this
Section 3.01;

19

 

     (x) that Notes must be surrendered to the Paying Agent to collect payment of
the Change in Control Purchase Price;

     (xi) that the Change in Control Purchase Price for any Note as to which a
Change in Control Purchase Notice has been duly given and not withdrawn, together
with any accrued interest payable with respect thereto, will be paid on or prior to
the third Trading Day following the later of the Change in Control Purchase Date and
the time of surrender of such Note;

     (xii) briefly, the conversion rights of the Notes;

     (xiii) the procedures for withdrawing a Change in Control Purchase Notice;

     (xiv) that, unless the Company defaults in making payment of such Change in
Control Purchase Price and interest due, if any, interest on Notes surrendered for
purchase will cease to accrue on and after the Change in Control Purchase Date; and

     (xv) the CUSIP number of the Notes.

     (c) A Holder may exercise its rights specified in Section 3.01(a) by delivery of a
written notice of purchase (a “Change in Control Purchase Notice”) to the Paying Agent at
any time prior to the Close of Business on the Change in Control Purchase Date, stating:

     (i) the certificate number of the Note which the Holder will deliver to be
purchased, if Certificated Notes have been issued, or notice compliant with the
relevant DTC procedures if the Notes are not certificated;

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

     (iii) that such Note shall be purchased pursuant to the terms and conditions
specified in this Article 3.

          The delivery of such Note to the Paying Agent prior to, on or after the Change in Control
Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent shall
be a condition to the receipt by the Holder of the Change in Control Purchase Price therefor;
provided, however, that such Change in Control Purchase Price shall be so paid pursuant to this
Section 3.01 only if the Note so delivered to the Paying Agent shall conform in all respects to the
description thereof set forth in the related Change in Control Purchase Notice.

          The Company shall purchase from the Holder thereof, pursuant to this Section 3.01, a portion
of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000.
Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase
of such portion of such Note.

20

 

          Any purchase by the Company contemplated pursuant to the provisions of this Section 3.01 shall
be consummated by the delivery of the consideration to be received by the Holder (together with
accrued and unpaid interest) on or prior to the third Business Day following the later of the
Change in Control Purchase Date and the time of delivery of the Note to the Paying Agent in
accordance with this Section 3.01.

          Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the
Change in Control Purchase Notice contemplated by this Section 3.01(c) shall have the right to
withdraw such Change in Control Purchase Notice at any time prior to the Close of Business on the
Change in Control Purchase Date by delivery of a written notice of withdrawal to the Paying Agent
in accordance with Section 3.02.

          The Paying Agent shall promptly notify the Company of the receipt by it of any Change in
Control Purchase Notice or written withdrawal thereof.

          There shall be no purchase of any Notes pursuant to this Section 3.01 if there has occurred
(prior to, on or after, as the case may be, the giving, by the Holders of such Notes, of the
required Change in Control Purchase Notice) and is continuing an Event of Default (other than a
default in the payment of the Change in Control Purchase Price). The Paying Agent will promptly
return to the respective Holders thereof any Notes (x) with respect to which a Change in Control
Purchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the
continuance of an Event of Default (other than a default in the payment of the Change in Control
Purchase Price) in which case, upon such return, the Change in Control Purchase Notice with respect
thereto shall be deemed to have been withdrawn.

     Section 3.02 Effect of Change in Control Purchase Notice.

     (a) Upon receipt by the Paying Agent of the Change in Control Purchase Notice specified
in Section 3.01(c), the Holder of the Note in respect of which such Change in
Control Purchase Notice was given shall (unless such Change in Control Purchase Notice
is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive
solely the Change in Control Purchase Price and any accrued and unpaid interest, with
respect to such Note. Such Change in Control Purchase Price and interest shall be paid to
such Holder, subject to receipt of funds by the Paying Agent, on or prior to the third
Business Day following the later of (x) the Change in Control Purchase Date, with respect to
such Note (provided the conditions in Section 3.01(c) have been satisfied) and (y) the time
of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by
Section 3.01(c). Notes in respect of which a Change in Control Purchase Notice has been
given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after
the date of the delivery of such Change in Control Purchase Notice unless such Change in
Control Purchase Notice has first been validly withdrawn as specified in the following two
paragraphs.

     (b) A Change in Control Purchase Notice may be withdrawn by means of a written notice
of withdrawal delivered to the office of the Paying Agent in accordance with the Change in
Control Purchase Notice at any time prior to the Close of Business on the Change in Control
Purchase Date specifying:

21

 

     (i) the certificate number of the Note which the Holder will deliver to be
purchased, if Certificated Notes have been issued, or notice compliant with the
relevant DTC procedures, if the Notes are not certificated,

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

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

          A written notice of withdrawal of a Change in Control Purchase Notice may be in the form set
forth in the preceding paragraph.

     Section 3.03 Deposit of Change in Control Purchase Price. Prior to 1:00 p.m. (New
York City time) on or prior to the third Business Day following the Change in Control Purchase
Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a
Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and
hold in trust as provided in Section 2.04) an amount of money (in immediately available funds if
deposited on such Trading Day) sufficient to pay the aggregate Change in Control Purchase Price of
all the Notes or portions thereof which are to be purchased as of the Change in Control Purchase
Date.

     If the Trustee or the Paying Agent holds money sufficient to pay the Change in Control
Purchase Price of a Note on the third Business Day following the Change in Control Purchase Date in
accordance with the terms hereof, then, immediately after the Change in Control Purchase Date,
interest on such Note will cease to accrue, whether or not the Note is delivered to
the Trustee or the Paying Agent, and all other rights of the holder shall terminate, other than the
right to receive the Change in Control Purchase Price upon delivery of the Note.

     Section 3.04 Notes Purchased In Part. Any Note which is to be purchased only in part
shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly
authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver
to the Holder of such Note, without service charge, a new Note or Note, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to, and in exchange
for, the portion of the principal amount of the Note so surrendered that is not purchased.

     Section 3.05 Covenant To Comply With Securities Laws Upon Repurchase of Notes. When
complying with the provisions of Section 3.01 (provided, that such offer or purchase constitutes an
“issuer tender offer” for purposes of Rule 13e-4 (which term, as used herein, includes any
successor provision thereto) under the Exchange Act at the time of such offer or purchase), and
subject to any exemptions available under applicable law, the Company shall:

22

 

     (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor provision) under the
Exchange Act, as applicable;

     (b) file the related Schedule TO (or any successor schedule, form or report) if
required under the Exchange Act, as applicable;

     (c) otherwise comply with all federal and state securities laws so as to permit the
rights and obligations under Section 3.01 to be exercised in the time and in the manner
specified therein.

          To the extent that the provisions of any securities laws or regulations conflict with the
provisions of Section 3.01, the Company’s compliance with such laws and regulations shall not in
and of itself cause a breach of its obligations under Section 3.01.

ARTICLE 4

York City time) on the due date of any principal of or interest on any Notes, or any
purchase price of the Notes, the Company will deposit with the Trustee (or Paying Agent)
money in immediately available funds sufficient to pay such amounts, provided
that if the Company or any Affiliate of the Company is acting as Paying Agent, it will,
on or before each due date, segregate and hold in a separate trust fund for the benefit of

otherwise disposed of as provided in the Indenture. In each case the Company will promptly
notify the Trustee of its compliance with this paragraph.

     (b) An installment of principal or interest will be considered paid on the date due if
the Trustee (or Paying Agent, other than the Company or any Affiliate of the Company) holds

will be considered paid on the due date only if paid to the Holders.

overdue installments of interest at the rate per annum specified in the Notes plus 2%.

     (d) Payments in respect of the Notes represented by the Global Notes are to be made by

transfer of immediately available funds to the accounts specified by the Holders thereof or,
if no such account is specified, by mailing a check to each Holder’s registered address.

23

 

     Section 4.02 Maintenance of Office or Agency. The Company will maintain in the United
States, an office or agency where Notes may be surrendered for registration of transfer or exchange
or for presentation for payment and where notices and demands to or upon the Company in respect of
the Notes and the Indenture may be served. The Company hereby initially designates the Corporate
Trust Office of the Trustee as such office of the Company. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such office or agency.
If at any time the Company fails to maintain any such required office or agency or fails to furnish
the Trustee with the address thereof, such presentations, surrenders, notices and demands may be
made or served to the Trustee.

          The Company may also from time to time designate one or more other offices or agencies where
the Notes may be surrendered or presented for any of such purposes and may from time to time
rescind such designations. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other office or agency.

     Section 4.03 Existence. The Company will do or cause to be done all things necessary
to preserve and keep in full force and effect its existence and the existence, rights and
franchises of the Company, provided that the Company is not required to preserve any such right or
franchise if the preservation thereof is no longer desirable in the conduct of the business of the
Company; and
provided further that this Section does not prohibit any transaction otherwise permitted by
Section 5.01.

     Section 4.04 Rule 144A Information and Annual Reports.

     (a) At any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act,
the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon
conversion thereof shall, at such time, constitute “restricted securities” within the
meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and
shall, upon written request, provide to any Noteholder, beneficial owner or prospective
purchaser of Notes or any shares of Common Stock issued upon conversion of any Notes, the
information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to
facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under
the Securities Act.

     (b) The Company shall deliver to the Trustee, such annual reports, information,
documents and other reports that are filed with the Commission, copies of the Company’s
annual reports (which shall contain audited financial statements of the Company) and of the
information, documents and other reports (or copies of such portions of any of the foregoing
as the Commission may by rules and regulations prescribe) that the Company files with the
Commission pursuant to Section 13 or Section 15(d) of the Exchange Act when and if (and only
if) the Company makes such filings with the Commission; provided that any such information,
documents or reports required to be filed with the Commission shall be deemed delivered to
the Trustee at the same time the same is filed with the Commission. The Company shall be
deemed to have complied with the previous sentence to the extent that the Company shall have
filed or furnished such information, documents or reports to the SEC via EDGAR (or any
successor electronic

24

 

delivery procedure). In the event the Company is at any time no longer
subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act,
the Company shall continue to provide the Trustee and, upon written request, to each
Noteholder, annual and quarterly reports containing substantially the same information as
would have been required to be filed with the SEC had the Company continued to have been
subject to such reporting requirements. In such event, such annual and quarterly reports
shall be provided at substantially similar times as the Company would have been required to
provide reports had it continued to have been subject to such reporting requirements.

     Section 4.05 Reports to Trustee.

     (a) The Company will deliver to the Trustee within 120 days after the end of each
fiscal year a certificate from the principal executive, financial or accounting officer of
the Company stating that the officer has conducted or supervised a review of the activities
of the Company and its Subsidiaries and their performance under the Indenture and that,
based upon such review, the Company has fulfilled its obligations hereunder or, if there has
been a Default, specifying the Default and its nature and status.

     (b) The Company will deliver to the Trustee, as soon as possible and in any event
within 30 days after the Company becomes aware or should reasonably become aware of
the occurrence of a Default, an Officers’ Certificate setting forth the details of the
Default, and the action which the Company proposes to take with respect thereto.

     Section 4.06 Stay, Extension and Usury Laws. The Company covenants (to the extent
that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, which may affect the covenants or the performance
of this Indenture; and the Company (in each case, to the extent that it may lawfully do so) hereby
covenants that it will not, by resort to any such law to the extent it would hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

     Section 4.07 Payment of Additional Interest. If Additional Interest is payable by the
Company pursuant to the Registration Rights Agreement or pursuant to Section 6.02(c) of this
Indenture, the Company shall deliver to the Trustee a certificate to that effect stating (i) the
amount of such Additional Interest that is payable, (ii) the reason why such Additional Interest is
payable and (iii) the date on which such Additional Interest is payable. Unless and until a Trust
Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no
such Additional Interest is payable. If the Company has paid Additional Interest directly to the
Persons entitled to it, the Company shall deliver to the Trustee a certificate setting forth the
particulars of such payment.

ARTICLE 5

CONSOLIDATION, MERGER, SALE OR LEASE OF ASSETS

     Section 5.01 Consolidation, Merger, Sale or Lease of Assets by the Company.

25

 

     (a) The Company, without the consent of the Holders of any of the outstanding Notes,
may

     (i) consolidate with or merge with or into any Person, or

     (ii) sell, convey, transfer, or otherwise dispose of or lease all or
substantially all of its assets as an entirety or substantially an entirety, in one
transaction or a series of related transactions, to any Person; provided that

	 	(A)	 	either (x) the Company is the
continuing Person or (y) the resulting, surviving or transferee
Person is a corporation, partnership, limited liability company
or trust organized and validly existing under the laws of the
United States of America, any State thereof or the District of
Columbia and expressly assumes by supplemental indenture all of
the obligations of the Company under the Indenture and the Notes
and the Registration Rights Agreement;
	 
	 	(B)	 	immediately after giving effect
to the transaction, no Event of Default and no Default has
occurred and is continuing; and
	 
	 	(C)	 	the Company delivers to the
Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that the consolidation, merger, transfer or lease and
the supplemental indenture (if any) comply with the Indenture.

     (b) Upon the consummation of any transaction effected in accordance with these
provisions, if the Company is not the continuing Person, the resulting, surviving or
transferee Person will succeed to, and be substituted for, and may exercise every right and
power of, the Company under the Indenture and the Notes with the same effect as if such
successor Person had been named as the Company in the Indenture. Upon such substitution,
except in the case of a lease, unless the successor is one or more of the Company’s
Subsidiaries, the Company will be released from its obligations under the Indenture and the
Notes.

ARTICLE 6

DEFAULT AND REMEDIES

     Section 6.01 Events of Default. An “Event of Default” occurs with respect to the
Notes if:

     (a) the Company defaults in the payment of the principal of any Note, or any Change in
Control Purchase Price when the same becomes due and payable on the Maturity Date, on the
Change in Control Purchase Date, upon acceleration, or otherwise;

26

 

     (b) the Company fails to provide the notice required by Section 3.01(b) on a timely
basis;

     (c) the Company defaults in the payment of interest (including any Additional Interest)
on any Note when the same becomes due and payable, and the default continues for a period of
30 days;

     (d) the Company fails to comply with any other covenant or agreement of the Company in
the Indenture or the Notes and the default or breach continues for a period of 60
consecutive days after written notice to the Company by the Trustee or to the Company and
the Trustee by the Holders of 25% or more in aggregate principal amount of the Notes then
outstanding;

     (e) the Company fails to make any payment by the end of any applicable grace period
after maturity of any Debt in an amount in excess of $100,000,000 and continuance of such
failure, or (ii) there is an acceleration of Debt in an amount in excess of $100,000,000
because of a default with respect to such Debt without such Debt having been discharged or
such acceleration having been cured, waived, rescinded or annulled
within a period of 30 days after written notice to the Company by the Trustee or to the
Company and the Trustee by the Holders of not less than 25% in aggregate principal amount of
the Notes then outstanding; provided, however, if any such failure or acceleration referred
to in (i) or (ii) above shall cease or be cured, waived, rescinded or annulled, then the
Event of Default by reason thereof shall be deemed not to have occurred;

     (f) the Company or any Significant Subsidiary, pursuant to or under or within the
meaning of any Bankruptcy Law, (i) commences a voluntary case or proceeding; (ii) consents
to the entry of an order for relief against it in an involuntary case or proceeding or the
commencement of any case against it; (iii) consents to the appointment of any receiver,
trustee, assignee, liquidator, custodian or similar official of it or for any substantial
part of its property; (iv) makes a general assignment for the benefit of its creditors; (v)
files a petition in bankruptcy or answer or consent seeking reorganization or relief; or
(vi) consents to the filing of such petition or the appointment of or taking possession by
any receiver, trustee, assignee, liquidator, custodian or similar official; or

     (g) a court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that (i) is for relief against the Company or any Significant Subsidiary in an
involuntary case or proceeding, or adjudicates the Company or any Significant Subsidiary
insolvent or bankrupt; (ii) appoints any receiver, trustee, assignee, liquidator, custodian
or similar official of the Company or any Significant Subsidiary or for any substantial part
of its property; or (iii) orders the winding up or liquidation of the Company or any
Significant Subsidiary, and the order or decree remains unstayed and in effect for 60 days
(an event of default specified in clause (f) or (g) a “Bankruptcy Default”).

27

 

     Section 6.02 Acceleration.

     (a) Subject to Section 6.02(c), if an Event of Default, other than a Bankruptcy Default
with respect to the Company, occurs and is continuing under the Indenture, the Trustee or
the Holders of at least 25% in aggregate of the outstanding principal amount of the Notes,
by written notice to the Company (and to the Trustee if the notice is given by the Holders),
may, and the Trustee at the request of such Holders shall, declare the principal of and
accrued interest on the Notes to be immediately due and payable. Upon a declaration of
acceleration, such principal and interest will become immediately due and payable. If a
Bankruptcy Default occurs with respect to the Company, the principal of and accrued interest
on the Notes then outstanding will become immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

     (b) The Holders of a majority in principal amount of the outstanding Notes by written
notice to the Company and to the Trustee may waive all past defaults and rescind and annul
a declaration of acceleration with respect to such Notes and its consequences if

     (i) all existing Events of Default, other than the nonpayment of the principal
of, premium, if any, and interest on the Notes that have become due solely by the
declaration of acceleration, have been cured or waived, and

     (ii) the rescission would not conflict with any judgment or decree of a court
of competent jurisdiction.

     (c) Notwithstanding Section 6.02(a) or any other provision of this Indenture to the
contrary, the sole remedy for any violation of any obligations the Company may be deemed to
have pursuant to Section 314(a)(1) of the Trust Indenture Act shall be the accrual of
Additional Interest on the Notes at a rate of 0.25% per annum, payable semiannually on each
Interest Payment Date based on the number of days of the relevant interest period on which
the Company is deemed to be in violation of such section. In no event shall Additional
Interest accrue on the Notes at a per annum rate in excess of 0.25% per annum pursuant to
both this Indenture and the Registration Rights Agreement, taken together, regardless of the
number of events or circumstances giving rise to the requirement to pay such Additional
Interest.

     Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the
Trustee may pursue, in its own name or as trustee of an express trust, any available remedy by
proceeding at law or in equity to collect the payment of principal of and interest on the Notes or
to enforce the performance of any provision of the Notes or the Indenture. The Trustee may
maintain a proceeding even if it does not possess any of the Notes or does not produce any of them
in the proceeding.

     Section 6.04 Waiver of Past Defaults. Except as otherwise provided in Sections 6.02,
6.07 and 9.02(b), the Holders of a majority in principal amount of the outstanding Notes may, by
notice to the Trustee, waive an existing Default and its consequences. Upon such waiver, the
Default will cease to exist, and any Event of Default arising therefrom will be

28

 

deemed to have been
cured, but no such waiver will extend to any subsequent or other Default or impair any right
consequent thereon.

     Section 6.05 Control by Majority. The Holders of a majority in aggregate principal
amount of the outstanding Notes may 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.
However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture,
that may involve the Trustee in personal liability, or that the Trustee determines in good faith
may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such
direction, and may take any other action it deems proper that is not inconsistent with any such
direction received from Holders of Notes.

     Section 6.06 Limitation on Suits. A Holder may not institute any proceeding, judicial
or otherwise, with respect to the Indenture or the Notes, or for the appointment of a receiver or
trustee, or for any other remedy under the Indenture or the Notes, unless:

     (i) the Holder has previously given to the Trustee written notice of a
continuing Event of Default;

     (ii) Holders of at least 25% in aggregate principal amount of outstanding Notes
have made written request to the Trustee to institute proceedings in respect of the
Event of Default in its own name as Trustee under the Indenture;

     (iii) Holders have offered to the Trustee indemnity reasonably satisfactory to
the Trustee against any costs, liabilities or expenses to be incurred in compliance
with such request;

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

     (v) during such 60-day period, the Holders of a majority in aggregate principal
amount of the outstanding Notes have not given the Trustee a direction that is
inconsistent with such written request.

     Section 6.07 Rights of Holders to Receive Payment. Notwithstanding anything to the
contrary, the right of a Holder of a Note to receive payment of principal of or interest on its
Note on or after the Stated Maturities thereof, or to bring suit for the enforcement of any such
payment on or after such respective dates, may not be impaired or affected without the consent of
that Holder.

     Section 6.08 Collection Suit by Trustee. If an Event of Default in payment of
principal or interest specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust for the whole
amount of principal and accrued interest remaining unpaid, together with interest on overdue
principal and, to the extent lawful, overdue installments of interest, in each case at the rate
specified in the Notes, and such further amount as is sufficient to cover the costs and expenses of

29

 

collection, including the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and any other amounts due the Trustee hereunder.

     Section 6.09 Trustee May File Proofs of Claim. The Trustee may file proofs of claim
and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders
allowed in any judicial proceedings relating to the Company or its creditors or property, and is
entitled and empowered to collect, receive and distribute any money, securities or other property
payable or deliverable upon conversion or exchange of the Notes or upon any such claims. Any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, if the Trustee
consents to the making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agent and counsel, and any other amounts due the Trustee hereunder. Nothing in the
Indenture will be deemed to empower the Trustee to authorize or consent to, or accept or adopt on
behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting
the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of
the claim of any Holder in any such proceeding.

     Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article,
it shall pay out the money in the following order:

          First: to the Trustee for all amounts due hereunder;

       Second: to Holders for amounts then due and unpaid for principal of and interest on
the Notes, ratably, without preference or priority of any kind, according to the amounts due
and payable on the Notes for principal and interest; and

          Third: to the Company or as a court of competent jurisdiction may direct.

          The Trustee, upon written notice to the Company, may fix a record date and payment date for
any payment to Holders pursuant to this Section. At least 15 days before such record date, the
Trustee shall mail to each Noteholder and the Company a notice that states the record date, the
payment date and the amount to be paid.

     Section 6.11 Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted a proceeding to enforce any right or remedy under the Indenture and the proceeding has
been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or
to the Holder, then, subject to any determination in the proceeding, the Company, the Trustee and
the Holders will be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Company, the Trustee and the Holders will continue as
though no such proceeding had been instituted.

     Section 6.12 Undertaking for Costs. In any suit for the enforcement of any right or
remedy under the Indenture or in any suit against the Trustee for any action taken or omitted by it
as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an

30

 

undertaking to pay the costs of the suit, and the court may assess reasonable costs, including
reasonable attorneys fees, against any party litigant (other than the Trustee) in the suit having
due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section does not apply to a suit by a Holder to enforce payment of principal of or interest on any
Note on the respective due dates, or a suit by Holders of more than 10% in principal amount of the
outstanding Notes.

     Section 6.13 Rights and Remedies Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders under this
Indenture is intended to be exclusive of any other right or remedy, and all such rights and
remedies are, to the extent permitted by law, cumulative and in addition to every other right and
remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion
or exercise of any other right or remedy.

     Section 6.14 Delay or Omission Not Waiver. No delay or omission of the Trustee or of
any Holder to exercise any right or remedy accruing upon any Event of Default will impair any such
right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

ARTICLE 7

THE TRUSTEE

     Section 7.01 General.

     (a) The duties and responsibilities of the Trustee are as provided by the Trust
Indenture Act and as set forth herein. Whether or not expressly so provided, every
provision of the Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee is subject to this Article.

     (b) Except during the continuance of an Event of Default, the Trustee need perform only
those duties that are specifically set forth in the Indenture and no others, and no implied
covenants or obligations will be read into the Indenture against the Trustee. In case an
Event of Default has occurred and is continuing, the Trustee shall exercise those rights and
powers vested in it by the Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

     (c) No provision of the Indenture shall be construed to relieve the Trustee from
liability for its own negligent action, its own negligent failure to act or its own willful
misconduct.

31

 

     Section 7.02 Certain Rights of Trustee. Subject to Trust Indenture Act Sections
315(a) through (d):

     (a) In the absence of bad faith on its part, the Trustee may rely, and will be
protected in acting or refraining from acting, upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper Person. The Trustee need not investigate
any fact or matter stated in the document, but, in the case of any document
which is specifically required to be furnished to the Trustee pursuant to any provision
hereof, the Trustee shall examine the document to determine whether it conforms to the
requirements of the Indenture (but need not confirm or investigate the accuracy of
mathematical calculations or other facts stated therein). The Trustee, in its discretion,
may make further inquiry or investigation into such facts or matters as it sees fit.

     (b) Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel conforming to Section 12.06 and the Trustee will not be
liable for any action it takes or omits to take in good faith in reliance on the certificate
or opinion.

     (c) The Trustee may act through its attorneys and agents and will not be responsible
for the misconduct or negligence of any agent appointed with due care.

     (d) The Trustee will be under no obligation to exercise any of the rights or powers
vested in it by the Indenture at the request or direction of any of the Holders, unless such
Holders have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities that might be incurred by it in compliance with such request or
direction.

     (e) The Trustee will not be liable for any action it takes or omits to take in good
faith that it believes to be authorized or within its rights or powers or for any action it
takes or omits to take in accordance with the direction of the Holders in accordance with
Section 6.05 relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under the Indenture.

     (f) The Trustee may consult with counsel, and the written advice of such counsel or any
Opinion of Counsel will be full and complete authorization and protection in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

     (g) No provision of the Indenture will require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of its duties hereunder,
or in the exercise of its rights or powers, unless it receives indemnity satisfactory to it
against any loss, liability or expense.

     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

32

 

Company or
its Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the
same with like rights. However, the Trustee is subject to Trust Indenture Act Sections 310(b) and
311. For purposes of Trust Indenture Act Section 311(b)(4) and (6):

     (a) “cash transaction” means any transaction in which full payment for goods or
securities sold is made within seven days after delivery of the goods or securities in
currency or in checks or other orders drawn upon banks or bankers and payable upon
demand; and

     (b) “self-liquidating paper” means any draft, bill of exchange, acceptance or
obligation which is made, drawn, negotiated or incurred for the purpose of financing the
purchase, processing, manufacturing, shipment, storage or sale of goods, wares or
merchandise and which is secured by documents evidencing title to, possession of, or a lien
upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale
of the goods, wares or merchandise previously constituting the security, provided the
security is received by the Trustee simultaneously with the creation of the creditor
relationship arising from the making, drawing, negotiating or incurring of the draft, bill
of exchange, acceptance or obligation.

     Section 7.04 Trustee’s Disclaimer. The Trustee (i) makes no representation as to the
validity or adequacy of the Indenture or the Notes, (ii) is not accountable for the Company’s use
or application of the proceeds from the Notes and (iii) is not responsible for any statement in the
Notes other than its certificate of authentication.

     Section 7.05 Notice of Default. If any Default occurs and is continuing and is known
to the Trustee, the Trustee will send notice of the Default to each Holder within 90 days after it
occurs, unless the Default has been cured; provided that, except in the case of a default in the
payment of the principal of or interest on any Note, the Trustee may withhold the notice if and so
long as the board of directors, the executive committee or a trust committee of directors of the
Trustee in good faith determines that withholding the notice is in the interest of the Holders.
Notice to Holders under this Section will be given in the manner and to the extent provided in
Trust Indenture Act Section 313(c).

     Section 7.06 Reports by Trustee to Holders. Within 60 days after each May 15,
beginning with May 15, 2007, the Trustee will mail to each Holder, as provided in Trust Indenture
Act Section 313(c), a brief report dated as of such May 15, if required by Trust Indenture Act
Section 313(a), and file such reports with each stock exchange upon which its Notes are listed and
with the Commission as required by Trust Indenture Act Section 313(d).

     Section 7.07 Compensation and Indemnity.

     (a) The Company will pay the Trustee compensation as agreed upon in writing for its
services. The compensation of the Trustee is not limited by any law on compensation of a
Trustee of an express trust. The Company will reimburse the Trustee upon request for all
reasonable out-of-pocket expenses, disbursements and advances incurred or made by the
Trustee, including the reasonable compensation and expenses of the Trustee’s agents and
counsel.

33

 

     (b) The Company will indemnify the Trustee for, and hold it harmless against, any loss
or liability or expense incurred by it without negligence or bad faith on its part arising
out of or in connection with the acceptance or administration of the Indenture and its
duties under the Indenture and the Notes, including the costs and expenses of defending
itself against any claim or liability and of complying with any process served upon it or
any of its officers in connection with the exercise or performance of any of its powers or
duties under the Indenture and the Notes.

     (c) To secure the Company’s payment obligations in this Section, the Trustee will have
a lien prior to the Notes on all money or property held or collected by the Trustee, in its
capacity as Trustee, except money or property held in trust to pay principal of, and
interest on particular Notes.

     Section 7.08 Replacement of Trustee.

     (a)
(i) The Trustee may resign at any time by written notice to the Company.

   (ii) The Holders of a majority in principal amount of the outstanding Notes may
remove the Trustee by written notice to the Trustee.

  (iii) If the Trustee is no longer eligible under Section 7.10 or in the
circumstances described in Trust Indenture Act Section 310(b), any Holder that
satisfies the requirements of Trust Indenture Act Section 310(b) may petition any
court of competent jurisdiction for the removal of the Trustee and the appointment
of a successor Trustee.

  (iv) The Company may remove the Trustee if: (A) the Trustee is no longer
eligible under Section 7.10; (B) the Trustee is adjudged a bankrupt or an insolvent;
(C) a receiver or other public officer takes charge of the Trustee or its property;
or (D) the Trustee becomes incapable of acting.

A resignation or removal of the Trustee and appointment of a successor Trustee will become
effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

     (b) If the Trustee has been removed by the Holders, Holders of a majority in principal
amount of the Notes may appoint a successor Trustee with the consent of the Company.
Otherwise, if the Trustee resigns or is removed, or if a vacancy exists in the office of
Trustee for any reason, the Company will promptly appoint a successor Trustee. If the
successor Trustee does not deliver its written acceptance within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a
majority in principal amount of the outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

     (c) Upon delivery by the successor Trustee of a written acceptance of its appointment
to the retiring Trustee and to the Company, (i) the retiring Trustee will transfer all
property held by it as Trustee to the successor Trustee, subject to the lien provided for in
Section 7.07(c), (ii) the resignation or removal of the retiring Trustee will

34

 

become effective, and (iii) the successor Trustee will have all the rights, powers and
duties of the Trustee under the Indenture. Upon request of any successor Trustee, the
Company will execute any and all reasonable instruments for fully and vesting in and
confirming to the successor Trustee all such rights, powers and trusts. The Company will
give notice of any resignation and any removal of the Trustee and each appointment of a
successor Trustee to all Holders, and include in the notice the name of the successor
Trustee and the address of its Corporate Trust Office.

     (d) Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s
obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

     (e) The Trustee agrees to give the notices provided for in, and otherwise comply with,
Trust Indenture Act Section 310(b).

     Section 7.09 Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate trust business (including the
administration of this Indenture) to, another corporation or national banking association, the
resulting, surviving or transferee corporation or national banking association without any further
act will be the successor Trustee with the same effect as if the successor Trustee had been named
as the Trustee in the Indenture.

     Section 7.10 Eligibility. The Indenture must always have a Trustee that satisfies the
requirements of Trust Indenture Act Section 310(a) and has a combined capital and surplus of at
least $25,000,000 as set forth in its most recent published annual report of condition.

     Section 7.11 Money Held in Trust. The Trustee will not be liable for interest on any
money received by it except as it may agree with the Company. Money held in trust by the Trustee
need not be segregated from other funds except to the extent required by law and except for money
held in trust under Article 8.

ARTICLE 8

DISCHARGE

     Section 8.01 Satisfaction and Discharge of the Indenture.

     (a) This Indenture shall cease to be of further effect if either: (i) all outstanding
Notes (other than Notes replaced pursuant to Section 2.07) have been delivered to the
Trustee for cancellation or (ii) all outstanding Notes have become due and payable on the
Maturity Date or upon repurchase pursuant to Article 3, and the Company irrevocably
deposits, prior to the applicable date on which such payment is due and payable, with the
Trustee or the Paying Agent (if the Paying Agent is not the Company or any of its
Affiliates) Cash, and, if applicable as herein provided and in accordance herewith, such
other consideration, sufficient to pay all amounts due and owing on all outstanding
Notes (other than Notes replaced pursuant to Section 2.07) on the Maturity Date or the
Change

35

 

in Control Purchase Date, as the case may be; provided that, in either case, the
Company pays to the Trustee all other sums payable hereunder by the Company.

     (b) The Company may exercise its satisfaction and discharge option with respect to the
Notes only if:

     (i) no Default or Event of Default with respect to the Notes shall exist on the
date of such deposit;

     (ii) such deposit shall not result in a breach or violation of, or constitute a
Default or Event of Default under, this Indenture or any other agreement or
instrument to which the Company is a party or by which it is bound; and

     (iii) the Company has delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence
of Defaults and Events of Default and as to any factual matters), each stating that
all conditions precedent provided for herein relating to the satisfaction and
discharge of this Indenture have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Company to the Trustee under Section 7.07 shall survive and, if money shall have been deposited
with the Trustee pursuant to clause (a) of this Section, the provisions of Section 2.03, Section
2.04, Section 2.05, Section 2.06, Section 2.07, Section 2.12, Section 3.01, Article 5, Article 10
and this Article 8, shall survive and the Company shall be required to make all payments and
deliveries required by such Sections or Articles, as the case may be, irrespective of any prior
satisfaction and discharge until the Notes have been paid in full.

     Section 8.02 Application of Trust Money. Subject to the provisions of Section 8.03,
the Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money
deposited with it pursuant to Section 8.01 and shall apply the deposited money in accordance with
this Indenture and the Notes to the payment of the principal amount of and interest on the Notes.

     Section 8.03 Repayment to Company. The Trustee and each Paying Agent shall promptly
pay to the Company upon request any excess money (x) deposited with them pursuant to Section 8.01
and (y) held by them at any time.

The Trustee and each Paying Agent shall also pay to the Company upon request any money held by them
for the payment of the principal amount of Notes or interest thereon that remains unclaimed for two
years after a right to such money has matured (which maturity shall occur, for the avoidance of
doubt, on the Maturity Date or the Change in Control Purchase Date (with respect to any Notes
repurchased pursuant to Article 3)); provided, however, that the Trustee or
such Paying Agent, before being required to make any such payment, may at the expense of the
Company cause to be mailed to each Holder entitled to such money or publish in a newspaper of
general circulation in the City of New York notice that such money remains unclaimed and that after
a date specified therein, which shall be at least 30 days from the date of such mailing or
publication, any unclaimed balance of such money then remaining will be repaid to the

36

 

Company.
After payment to the Company, Holders entitled to money must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another person.

     Section 8.04 Reinstatement. If the Trustee or any Paying Agent is unable to apply any
money in accordance with Section 8.02 by reason of any legal proceeding or by reason of any order
or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then 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 such Paying Agent is permitted to apply all such money in accordance with Section
8.02; provided, however, that if the Company has made any payment of the principal amount of or
interest on any Notes because of the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive any such payment from the money
held by the Trustee or such Paying Agent.

ARTICLE 9

AMENDMENTS, SUPPLEMENTS AND WAIVERS

     Section 9.01 Amendments Without Consent of Holders. The Company and the Trustee may
amend or supplement the Indenture or the Notes without notice to or the consent of any Noteholder:

     (a) to cure any ambiguity, omission, defect or inconsistency in the Indenture or the
Notes;

     (b) to comply with Article 5 or Section 10.12;

     (c) to comply with the Trust Indenture Act or any amendment thereto, or to comply with
any requirements of the Commission in connection with the qualification of the Indenture
under the Trust Indenture Act;

     (d) to evidence and provide for the acceptance of an appointment hereunder by a
successor Trustee;

     (e) to provide for uncertificated Notes in addition to or in place of certificated
Notes;

     (f) to secure the Notes;

     (g) to add guarantees with respect to the Notes;

     (h) to add to the covenants of the Company for the benefit of the Holders or to
surrender any right or power herein conferred upon the Company;

     (i) to add any additional Events of Default;

     (j) to comply with the rules of any applicable securities depositary; or

37

 

     (k) to make any other change that does not materially adversely affect the rights of
any Holder.

     Section 9.02 Amendments With Consent of Holders.

     (a) Except as otherwise provided in Section 6.07 or paragraph (b), the Company and the
Trustee may amend the Indenture and the Notes with the written consent of the Holders of a
majority in principal amount of the outstanding Notes, and the Holders of a majority in
principal amount of the outstanding Notes by written notice to the Trustee may waive future
compliance by the Company with any provision of the Indenture or the Notes.

     (b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder
affected, an amendment or waiver may not

     (i) reduce the principal amount of, Change in Control Purchase Price with
respect to, or any premium or interest payment on any Note,

     (ii) make any Note payable in currency or securities other than that stated in
the Note,

     (iii) change the Stated Maturities of any installment of principal of any Note,

     (iv) make any change that adversely affects the Holders’ right to convert any
Note,

     (v) make any change that adversely affects the Holders’ right to require the
Company to purchase the Notes in accordance with the terms thereof and this
Indenture,

     (vi) impair the right to convert or receive any principal or interest payment
with respect to, a Note, or right to institute suit for the enforcement of any
payment with respect to, or conversion of, the Notes, or

     (vii) make any change in the percentage of the principal amount of the Notes
required for amendments or waivers.

     (c) It is not necessary for Noteholders to approve the particular form of any proposed
amendment, supplement or waiver, but is sufficient if their consent approves the substance
thereof.

     (d) An amendment, supplement or waiver under this Section will become effective on
receipt by the Trustee of written consents from the Holders of the requisite percentage in
principal amount of the outstanding Notes. After an amendment, supplement or waiver under
this Section becomes effective, the Company will send to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. The Company will send
supplemental indentures to Holders upon request. Any

38

 

failure of the Company to send such
notice, or any defect therein, will not, however, in any way impair or affect the validity
of any such supplemental indenture or waiver.

     (e) With respect to the amendments set forth in Section 9.01 and this Section 9.02, no
such amendment to cure any ambiguity, defect or inconsistency made solely to conform the
Indenture to the provisions of the description of the Notes as set forth in any final
offering memorandum will be deemed to adversely affect the interests of the Noteholders.

     Section 9.03 Effect of Consent.

     (a) After an amendment, supplement or waiver becomes effective, it will bind every
Holder unless it is of the type requiring the consent of each Holder affected. If the
amendment, supplement or waiver is of the type requiring the consent of each Holder
affected, the amendment, supplement or waiver shall bind each Holder that has consented to
it and every subsequent Holder of a Note that evidences the same debt as the Note of the
consenting Holder.

     (b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may
require the Holder to deliver it to the Trustee so that the Trustee may place an appropriate
notation of the changed terms on the Note and return it to the Holder, or exchange it for a
new Note that reflects the changed terms. The Trustee may also place an appropriate
notation on any Note thereafter authenticated. However, the effectiveness of the amendment,
supplement or waiver is not affected by any failure to annotate or exchange Notes in this
fashion.

     Section 9.04 Trustee’s Rights and Obligations. The Trustee is entitled to receive,
and will be fully protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted
by the Indenture. If the Trustee has received such an Opinion of Counsel, it shall sign the
amendment, supplement or waiver so long as the same does not adversely affect the rights of the
Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver
that affects the Trustee’s own rights, duties or immunities under the Indenture.

     Section 9.05 Conformity With Trust Indenture Act . Every supplemental indenture executed pursuant to this Article shall conform to the
requirements of the Trust Indenture Act.

     Section 9.06 Payments for Consents. Neither the Company nor any of its Subsidiaries
or Affiliates may, directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration
is offered to be paid or agreed to be paid to all Holders of the Notes that consent, waive or agree
to amend such term or provision within the time period set forth in the solicitation documents
relating to the consent, waiver or amendment.

ARTICLE 10

CONVERSION

     Section 10.01 Conversion Privilege. A Holder of a Note may convert such Note at any
time on or prior to the Close of Business on the Business Day immediately preceding the Maturity
Date upon the occurrence of any of the events set forth in paragraph 7(a), paragraph 7(b),
paragraph 7(c), paragraph 7(d) or paragraph 7(e) of the Notes, subject to the provisions of this
Article 10. Except as set forth below under Section 10.11, if a Holder surrenders its Notes for
conversion, such Holder will receive, in respect of each $1,000 of principal amount of Notes to be
converted:

     (a) Cash in an amount equal to the lesser of (A) $1,000 and (B) the Conversion Value
(the “Required Cash Amount”), and

     (b) if the Conversion Value is greater than $1,000, a number of shares of Common Stock
(the “Remaining Shares”), equal to the sum of the Daily Share Amounts for each of the twenty
consecutive Trading Days in the Conversion Reference Period, subject to the right of the
Company to deliver Cash in lieu of all or a portion of such Remaining Shares as described
below.

          By the Close of Business on the Business Day prior to the first scheduled Trading Day of the
applicable Conversion Reference Period, the Company may specify a percentage of the Daily Share
Amount that will be settled in Cash (the “Cash Percentage”) and will notify the Noteholder of such
Cash Percentage through written notice to the Trustee (the “Cash Percentage Notice”). If the
Company elects to specify a Cash Percentage, (x) the amount of Cash that the Company will deliver
pursuant to clause (b) of this Section 10.01 in respect of each Trading Day in the applicable
Conversion Reference Period will equal the product of: (i) the Cash Percentage, (ii) the Daily
Share Amount for such Trading Day, and (iii) the Volume Weighted Average Price of the Common Stock
for such Trading Day and (y) the number of shares of Common Stock deliverable in respect of each
Business Day in the applicable Conversion Reference Period (in lieu of the full Daily Share Amount
for such Trading Day pursuant to clause (b) above) will be a percentage of the Daily Share Amount
equal to 100% minus the Cash Percentage. If the
Company does not specify a Cash Percentage by the Close of Business on the Trading Day prior
to the first scheduled Trading Day of the applicable Conversion Reference Period, the Company shall
settle 100% of the Daily Share Amount for each Trading Day in the applicable Conversion Reference
Period with shares of Common Stock; provided, however, that the Company will pay Cash in lieu of
fractional shares otherwise issuable upon conversion of such Note, pursuant to Section 10.03
hereof. The Company may, at its option, revoke any Cash Percentage Notice through written notice
to the Trustee by the Close of Business on the Business Day prior to the scheduled first Trading
Day of the applicable Conversion Reference Period.

     (c) A Holder may convert a portion of the principal amount of a Note if the portion is
$1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to
conversion of all of a Note also apply to conversion of a portion of a Note.

40

 

     (d) In the event of a stock split, combination, dividend or any other event resulting
in an adjustment to the Conversion Rate pursuant to Section 10.06, 10.07, 10.08, 10.09 or
10.10, during the applicable Conversion Reference Period, appropriate adjustment to the
equation for calculating Conversion Value and Remaining Shares shall be made, as determined
by the Board of Directors.

     (e) Notes with respect to which a Change in Control Purchase Notice has been given by
the Holder may be converted pursuant to this Article 10 only if the Change in Control
Purchase Notice has been withdrawn in accordance with Section 3.02.

     (f) Whenever any event described in paragraph 7(a), paragraph 7(b), paragraph 7(c),
paragraph 7(d) or paragraph 7(e) of the Notes shall occur such that the Notes become
convertible as provided in this Article 10, the Company shall (x) issue a press release and
use its reasonable efforts to post such information on its website or otherwise publicly
disclose this information or (y) promptly deliver, in accordance with Section 12.03, written
notice of the convertibility of the Notes to the Trustee and each Noteholder and to the
Conversion Agent for the benefit of the Noteholders, which press release, website posting,
public disclosure or written notice, as the case may be, shall include:

     (i) a description of such event;

     (ii) a description of the periods during which the Notes shall be convertible
as provided in paragraph 7(a), paragraph 7(b), paragraph 7(c), paragraph 7(d) or
paragraph 7(e) of the Notes as a result of such event;

     (iii) a statement of whether an adjustment to the Conversion Rate shall take
effect in respect of such event pursuant to Section 10.13; and

     (iv) the procedures Noteholders must follow to convert their Notes in
accordance with this Article 10, including the name and address of the Conversion
Agent.

     Section 10.02 Conversion Procedure.

     (a) To convert a Note represented by a Global Note, a Noteholder must convert by
book-entry transfer to the Conversion Agent through the facilities of the DTC. To convert a
Note that is represented by a Certificated Note, a Noteholder must (1) complete and manually
sign a Conversion Notice, a form of which is on the back of the Note, and deliver such
Conversion Notice to the Conversion Agent, (2) surrender the Note to the Conversion Agent,
(3) if required by the Conversion Agent, furnish appropriate endorsement and transfer
documents, and (4) if required, pay all transfer or similar taxes. The Conversion Agent
shall, within one (1) Business Day of any Conversion Date, provide notice to the Company, as
set forth in Section 12.03, of the occurrence of such Conversion Date.

     (b) As promptly as practicable following the end of the Conversion Reference Period
applicable to the Notes being converted, the Company shall deliver to the Holder, through
the Conversion Agent, the Required Cash Amount and Remaining Shares, if any

41

 

(including Cash
in lieu of Remaining Shares pursuant to Section 10.01 hereof and
Cash in lieu of fractional shares pursuant to Section 10.03 hereof). The person in whose name the certificate
representing any shares is registered shall be treated as a stockholder of record on and
after the last Trading Day of the Conversion Reference Period; provided,
however, that no surrender of a Note on any date when the stock transfer books of
the Company shall be closed shall be effective to constitute the person or persons entitled
to receive the Remaining Shares upon such conversion as the record
holder or holders of such shares of Common Stock on such date, but such surrender 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 person shall no
longer be a Holder of such Note.

     (c) No payment or adjustment will be made for dividends on, or other distributions with
respect to, any Common Stock except as provided in this Article 10. Upon conversion of a
Note, a Noteholder will not receive, except as described below, any Cash payment
representing accrued interest. Instead, accrued interest will be deemed paid by the Cash
and/or shares of common stock, if any, received by the Noteholder upon conversion. Delivery
to the Noteholder of such Cash and/or shares of Common Stock will thus be deemed (1) to
satisfy the Company’s obligation to pay the principal amount of a Note, and (2) to satisfy
the Company’s obligation to pay accrued and unpaid interest on the Note. As a result, upon
conversion of a Note, accrued and unpaid interest on such Note is deemed paid in full rather
than cancelled, extinguished or forfeited.

     (d) Holders of Notes surrendered for conversion during the period from the Close of
Business on any Regular Record Date next preceding any Interest Payment Date to the opening
of business of such Interest Payment Date will receive the semiannual interest payable on
such Notes on the corresponding Interest Payment Date notwithstanding the conversion, and
such Notes upon surrender must be accompanied by funds equal to the amount of such payment;
provided that no such payment need be made (x) in connection with any conversion following
the Regular Record Date immediately preceding the
Maturity Date, (y) if the Company has specified a Change in Control Purchase Date that
is after a Regular Record Date and on or prior to the corresponding Interest Payment Date or
(z) to the extent of any Defaulted Interest, if any Defaulted Interest exists at the time of
conversion with respect to such Note. The Company shall not be required to convert any Notes
that are surrendered for conversion without payment of interest as required by this
paragraph.

     (e) If the Holder converts more than one Note at the same time, the Required Cash
Amount and the Remaining Shares, if any (together with the Cash payment, if any, in lieu of
fractional shares) shall be based on the total principal amount of the Notes converted.

     (f) If the last day on which a Note may be converted is a Legal Holiday, the Note may
be surrendered on the next succeeding day that is not a Legal Holiday.

42

 

     (g) Upon surrender of a Note that is converted in part, 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 unconverted portion of the Note surrendered.

     Section 10.03 Fractional Shares. The Company will not issue a fractional share of
Common Stock upon conversion of a Note. Instead, the Company will deliver Cash in lieu of a
fractional share based on arithmetic average of the Volume Weighted Average Price of Common Stock
for each of the twenty consecutive Trading Days of the Conversion Reference Period, rounded to the
nearest whole cent (the “Average Price”).

     Section 10.04 Taxes On Conversion. If a Holder converts a Note, the Company shall pay
any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common
Stock upon the conversion. However, the Holder shall pay any such tax which is due because the
Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion
Agent may refuse to deliver the certificates representing the Common Stock being issued in a name
other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax
which will be due because the Common Stock is to be delivered in a name other than the Holder’s
name. Nothing herein shall preclude any tax withholding required by law or regulations.

     Section 10.05 Company To Provide Common Stock.

          The Company shall, prior to issuance of any Notes under this Article 10, and from time to time
as may be necessary, reserve out of its authorized but unissued Common Stock a sufficient number of
shares of Common Stock to permit the delivery in respect of all outstanding Notes of the number of
Remaining Shares due upon conversion (assuming, for purposes of this sentence, that the Company
elects to deliver solely shares of Common Stock in respect of its obligation to deliver the
Remaining Shares).

          All shares of Common Stock delivered upon payment of the Remaining Shares, if applicable, upon
conversion of the Notes shall be newly issued shares or treasury shares, shall be duly and validly
issued and fully paid and nonassessable and shall be free from preemptive rights and free of any
lien or adverse claim.

          The Company will comply with all federal and state securities laws regulating the offer and
delivery of shares of Common Stock upon payment of the Remaining Shares, if applicable, upon
conversion of Notes, if any, and will list or cause to have quoted such shares of Common Stock on
each national securities exchange or in the over-the-counter market or such other market on which
the Common Stock is then listed or quoted.

          In addition, if any shares of Common Stock which would be issuable upon conversion of Notes
hereunder require registration with or approval of any governmental authority before such shares of
Common Stock may be issued upon such conversion, the Company will cause such shares of Common Stock
to be duly registered or approved, as the case may be.

43

 

     Section 10.06 Adjustment for Change In Capital Stock.

     (a) If the Company shall, at any time and from time to time while any of the Notes are
outstanding, issue a dividend or makes a distribution on its Common Stock payable in shares
of its Common Stock, then the Conversion Rate at the opening of business on the Ex-Dividend
Date for such dividend or distribution will be adjusted by multiplying such Conversion Rate
by a fraction:

     (i) the numerator of which shall be the sum of the number of shares of Common
Stock outstanding at the Close of Business on the Business Day immediately preceding
the Ex-Dividend Date for such dividend or distribution, plus the
total number of shares of Common Stock constituting such dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock
outstanding at the close of business on the Business Day immediately preceding such
Ex-Dividend Date.

          If any dividend or distribution of the type described in this Section 10.06(a) is declared but
not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would
then be in effect if such dividend or distribution had not been declared. Except as set forth in
the preceding sentence, in no event shall the Conversion Rate be decreased pursuant to this Section
10.06(a).

     (b) If the Company shall, at any time or from time to time while any of the Notes are
outstanding, subdivide or reclassify its outstanding shares of Common Stock into a greater
number of shares of Common Stock, then the Conversion Rate in effect at the opening of
business on the day upon which such subdivision becomes effective shall be proportionately
increased, and conversely, if the Company shall, at any time or from time to time while any
of the Notes are outstanding, combine or reclassify its outstanding shares of Common Stock
into a smaller number of shares of Common Stock, then the
Conversion Rate in effect at the opening of business on the day upon which such
combination or reclassification becomes effective shall be proportionately decreased. In
each such case, the Conversion Rate shall be adjusted by multiplying such Conversion Rate by
a fraction, the numerator of which shall be the number of shares of Common Stock outstanding
immediately after giving effect to such subdivision, combination or reclassification and the
denominator of which shall be the number of shares of Common Stock outstanding immediately
prior to such subdivision or combination. Such increase or reduction, as the case may be,
shall become effective immediately after the opening of business on the day upon which such
subdivision, combination or reclassification becomes effective.

     Section 10.07 Adjustment for Rights Issue. If the Company shall, at any time or from
time to time while the Notes are outstanding, distribute rights to all holders of its Common Stock
entitling them, for a period expiring within 60 days after the record date for such distribution,
to purchase shares of Common Stock at less than the average of the Closing Prices for the five
consecutive Trading Days immediately preceding the first public announcement of

44

 

the distribution,
the Conversion Rate shall be adjusted so that the same shall equal the rate determined by
multiplying the Conversion Rate in effect at the opening of business on the Ex-Dividend Date for
such distribution by a fraction:

	 	(x)	 	the numerator of which shall be the number of shares of Common
Stock outstanding at the close of business on the Business Day immediately
preceding the Ex-Dividend Date for such distribution, plus the total number of
additional shares of Common Stock so offered for purchase; and
	 
	 	(y)	 	the denominator of which shall be the number of shares of
Common Stock outstanding on the close of business on the Business Day
immediately preceding the Ex-Dividend Date for such distribution, plus the
number of shares of Common Stock that the aggregate offering price of the total
number of shares of Common Stock so offered would purchase at the Current
Market Price of the Common Stock on the declaration date for such distribution
(determined by multiplying such total number of shares of Common Stock so
offered by the exercise price of such rights and dividing the product so
obtained by such Current Market Price).

          Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such distribution.

          To the extent that shares of Common Stock are not delivered pursuant to such rights or upon
the expiration or termination of such rights, 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 been made on the basis of the delivery of only the number of shares of Common Stock actually
delivered. In the event that such rights are not so distributed, the Conversion Rate shall again
be adjusted to be the Conversion Rate which would then be in effect if the Ex-Dividend Date for
such distribution had not occurred. In determining whether any
rights entitle the holders to purchase shares of Common Stock at less than the average of the
Closing Prices for the five consecutive Trading Days immediately preceding the first public
announcement of the relevant distribution, and in determining the aggregate offering price of such
shares of Common Stock, there shall be taken into account any consideration received for such
rights and the value of such consideration if other than Cash, to be determined in good faith by
the Board of Directors. Except as set forth in this paragraph, in no event shall the Conversion
Rate be decreased pursuant to this Section 10.07.

     Section 10.08 Adjustment for Other Distributions.

     (a) If the Company shall, at any time or from time to time while the Notes are
outstanding, distribute to all holders of its Common Stock any of its Capital Stock, assets,
or debt securities or any rights, warrants or options to purchase securities of the Company
(excluding (w) any distribution of Capital Stock of, or similar equity interests in, a
Subsidiary or other business unit of the Company referred to in Section 10.08(b) below, (x)
any distributions described in Section 10.06(a) above, (y) any rights described in Section
10.07 above, (z) any cash dividends or other cash distributions referred to in

45

 

Section 10.09
below) (such Capital Stock, assets, debt securities or rights to purchase securities of the
Company being distributed hereinafter in this Section 10.08 called the “Distributed
Assets”), the Conversion Rate shall be increased so that the same shall be equal to the rate
determined by multiplying the Conversion Rate in effect immediately prior to the opening of
business on the Ex-Dividend Date with respect to such distribution by a fraction:

     (i) the numerator of which will be the Current Market Price of the Common
Stock, and

     (ii) the denominator of which will be the Current Market Price of the Common
Stock minus the fair market value, as determined by the Board of Directors, of the
portion of Distributed Assets so distributed applicable to one share of the Common
Stock (determined on the basis of the number of shares of Common Stock outstanding
on such Ex-Dividend Date).

          Such increase shall become effective immediately after the opening of business on the
Ex-Dividend Date for such distribution. In the event that such distribution is not so made, the
Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if
such distribution had not been declared. Except as set forth in the prior sentence, in no event
shall the Conversion Rate be decreased pursuant to this Section 10.08(a).

          If the Board of Directors determines the fair market value of any distribution for purposes of
this Section 10.08(a) by reference to the actual or when issued trading market for any Distributed
Assets comprising all or part of such distribution, it must in doing so consider the prices in such
market over the same period (the “Reference Period”) used in computing the Current Market Price for
purposes of clause (i) above, unless the Board of Directors determines in good faith that
determining the fair market value during the Reference Period would not be in the best interest of
the Holders.

     (b) With respect to an adjustment pursuant to this Section 10.08 where there has been a
payment of a dividend or other distribution on Common Stock of shares of capital stock of,
or similar equity interests in, a subsidiary or other business unit of the Company, the
Conversion Rate will be adjusted by multiplying the Conversion Rate in effect immediately
prior to the close of business on the record date with respect to such distribution by a
fraction:

     (i) the numerator of which shall be (a) the average of the closing sale prices
of the capital stock or similar equity interest distributed to holders of Common
Stock applicable to one share of Common Stock over the five Trading Days commencing
on and including the fifth Trading Day after the Ex-Dividend Date for such dividend
or distribution on the principal national securities exchange or inter-dealer
quotation system on which such securities are then listed or traded, plus (b) the
average of the Closing Prices over the five Trading Days commencing on and including
the fifth Trading Day after the Ex-Dividend Date for such dividend or distribution
(the “Average Sale Price”), and

46

 

     (ii) the denominator of which shall be the Average Sale Price.

     Section 10.09 Adjustment for Cash Dividends. If the Company shall, at any time or
from time to time while any of the Notes are outstanding, by dividend or otherwise, distribute to
all or substantially all holders of its shares of Common Stock, Cash (excluding (x) any
distributions described in Section 10.10 below or (y) any dividend or distribution in connection
with the Company’s liquidation, dissolution or winding up), then the Conversion Rate shall be
adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the opening of business of the Ex-Dividend Date for such distribution
by a fraction:

	 	(x)	 	the numerator of which shall be equal to the
Current Market Price per share of Common Stock; and
	 
	 	(y)	 	the denominator of which shall be equal to the
Current Market Price per share of Common Stock on such date, less the
amount of the distribution per share of Common Stock.

          Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such distribution. In the event that such distribution is not so made, the
Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if
such dividend or distribution had not been declared.

     Section 10.10 Adjustment for Certain Tender Offers. In case the Company or any of its
Subsidiaries shall, at any time or from time to time, while any of the Notes are outstanding,
distribute Cash or other consideration in respect of a tender offer or exchange offer made by the
Company or any Subsidiary for all or any portion of the Common Stock, where the sum of the
aggregate amount of such Cash distributed and the aggregate fair market value (as determined in
good faith by the Board of Directors, whose
determination shall be conclusive and set forth in a Board Resolution), as of the Expiration
Date (as defined below), of such other consideration distributed (such sum, the “Aggregate Amount”)
expressed as an amount per share of Common Stock validly tendered or exchanged, and not withdrawn,
pursuant to such tender offer or exchange offer as of the Expiration Time (as defined below) (such
tendered or exchanged shares of Common Stock, the “Purchased Shares”) exceeds the Closing Price per
share of the Common Stock on the first Trading Day immediately following the last date (such last
date, the “Expiration Date”) on which tenders or exchanges could have been made pursuant to such
tender offer or exchange offer (as the same may be amended through the Expiration Date), then, and
in each case, immediately after the close of business on such date, the Conversion Rate shall be
increased so that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the close of business on the Trading Day immediately following the
Expiration Date by a fraction:

	 	(x)	 	the numerator of which is equal to the sum of
(A) the Aggregate Amount and (B) the product of (I) an amount equal to
(1) the number of shares of Common Stock outstanding as of the last
time (the “Expiration Time”) at which tenders or exchanges could have
been made pursuant to such tender offer or exchange offer less (2)

47

 

	 	 	 	the Purchased Shares and (II) the Closing Price per share of the Common
Stock on the first Trading Day immediately following the Expiration
Date; and
	 
	 	(y)	 	the denominator of which shall be equal to the
product of (A) the number of shares of Common Stock outstanding as of
the Expiration Time (including all Purchased Shares) and (B) the
Closing Price per share of the Common Stock on the first Trading Day
immediately following the Expiration Date.

An adjustment, if any, to the Conversion Rate pursuant to this Section 10.10 shall become effective
immediately prior to the opening of business on the second Trading Day immediately following the
Expiration Date. In the event that the Company or a Subsidiary is obligated to purchase shares of
Common Stock pursuant to any such tender offer or exchange offer, but the Company or such
Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all
such purchases are rescinded, then the Conversion Rate shall again be adjusted to be the Conversion
Rate which would then be in effect if such tender offer or exchange offer had not been made.
Except as set forth in the preceding sentence, if the application of this Section 10.10 to any
tender offer or exchange offer would result in a decrease in the Conversion Rate, no adjustment
shall be made for such tender offer or exchange offer under this Section 10.10.

     Section 10.11 Provisions Governing Adjustment to Conversion Rate. Rights or warrants
distributed by the Company to all holders of Common Stock entitling the holders thereof to
subscribe for or purchase shares of the Company’s Capital 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 Common Stock; (ii)
are not exercisable; and (iii) are also issued in respect of
future issuances of Common Stock, shall be deemed not to have been distributed for purposes of
Section 10.06, Section 10.07, Section 10.08, Section 10.09 or Section 10.10 (and no adjustment to
the Conversion Rate under Section 10.06, Section 10.07, Section 10.08, Section 10.09 or Section
10.10 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights,
options 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 Section 10.08, except as set forth in
Section 10.23. 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), except as set forth in
Section 10.23. In addition, except as set forth in Section 10.23, 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 Section
10.06, Section 10.07, Section 10.08, Section 10.09 or Section 10.10 was made (including any
adjustment contemplated in Section 10.23), (1) in the case of any such rights, options or warrants

48

 

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, options
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.

     Section 10.12 Disposition Events. If any of the following events (any such event, a
“Disposition Event”) occurs:

     (a) any reclassification of the 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
subdivision or combination);

     (b) any merger, consolidation or other combination involving the Company; or

     (c) any sale or conveyance of all or substantially all the properties and assets of the
Company to any other Person;

in each case, as a result of which all of the holders of Common Stock shall be entitled to receive
Cash, securities or other property for their shares of Common Stock, the Company or the successor
or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture
(which shall comply with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture, if such supplemental indenture is then required to
so comply) providing that notwithstanding the provisions of Section 10.01, and subject to the
provisions of paragraph 7 of the Notes, the Conversion Value with respect to each $1,000 principal
amount of Notes converted following the effective date of any Disposition Event, shall be
calculated based on the kind and amount of Cash, securities or other property (collectively,
“Reference Property”) received upon the occurrence of such Disposition Event by a holder of Common
Stock holding, immediately prior to the transaction, a number of shares of Common Stock equal to
the Conversion Rate immediately prior to such Disposition Event; provided that if the Disposition
Event provides the holders of Common Stock with the right to receive more than a single type of
consideration determined based in part upon any form of stockholder election, the Reference
Property shall be comprised of the weighted average of the types and amounts of consideration
received by the holders of the Common Stock.

     If the Conversion Value of the Notes shall be based on Reference Property as set forth above,
the Company’s obligation to deliver the consideration described in Section 10.01 with respect to
each $1,000 principal amount of Notes tendered for conversion after the effective date of any such
Disposition Event, shall, notwithstanding anything to the contrary set forth in Section 10.01, be
settled in Cash and units of Reference Property (if applicable) and the Company shall deliver, as
promptly as practicable immediately following the last Trading Day of the Conversion Reference
Period:

49

 

	 	(1)	 	Cash in an amount equal to the lesser of (A) $1,000 and (B) the
Conversion Value, and
	 
	 	(2)	 	if the Conversion Value is greater than $1,000, (a) Cash equal
to the difference between the aggregate Conversion Value and $1,000, (b) an
amount in Reference Property, determined as set forth in Section 10.01(b), with
a fair market value, as determined by the Conversion Agent, equal to the
Conversion Value less $1,000 or (c) a combination thereof, at the Company’s
election, determined as set forth in Section 10.01(b); and
	 
	 	(3)	 	an amount in Cash in lieu of any fractional shares of Common
Stock calculated based on the Average Price,

provided that, in each case, (x) the Conversion Value and the Daily Share
Amounts, shall be determined as if the words “Volume Weighted Average Price per
share of Common Stock” in the definition of each such term were replaced by the
words “Volume Weighted Average Price per unit of Reference Property composed of the
kind and amount of Cash, securities or other property that a holder of one share of
Common Stock immediately prior to such Disposition Event would have owned or been
entitled to receive”, (y) the Volume Weighted Average Price shall be determined with
respect to such a unit of Reference Property and (z) references to “Remaining
Shares” and “shares of Common Stock” were instead references to “a unit of Reference
Property composed of the kind and amount of Cash, securities or other property that
a holder of one share of Common Stock immediately prior to such Disposition Event
would have owned or been entitled to receive.”

          Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent
as may be practicable to the adjustments provided for in this Article 10. If, in the case of any
such Disposition Event, the stock or other securities and assets receivable thereupon by a holder
of Common Stock includes shares of stock or other securities and assets of a Person other than the
successor or purchasing Person, as the case may be, in such Disposition Event, then such
supplemental indenture shall also be executed by such other Person and shall contain such
additional provisions to protect the interests of the Noteholders as the Board of Directors shall
reasonably consider necessary by reason of the foregoing.

          The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each Noteholder, at the address of such Noteholder as it appears on the register of the Notes
maintained by the Registrar, within 20 days after execution thereof. Failure to deliver such
notice shall not affect the legality or validity of such supplemental indenture.

          The above provisions of this Section 10.12 shall similarly apply to successive Disposition
Events.

If this Section 10.12 applies to any event or occurrence, none of Section 10.06, Section 10.07,
Section 10.08, Section 10.09 or Section 10.10 shall apply.

     Section 10.13 Adjustment to Conversion Rate Upon Change in Control Transactions,
Discretionary Adjustment.

     (a) If, after the Issue Date, a Change in Control occurs and a Holder elects to convert
its Notes in connection with such Change in Control, the Company will increase the
Conversion Rate for the Notes surrendered for conversion by a number of additional shares of
Common Stock (the “Make-Whole Shares”), as described in this Section 10.13. A conversion of
Notes will be deemed for the purposes of this Section 10.13 to be “in connection with” a
Change in Control transaction if the notice of conversion of the Notes is received by the
Conversion Agent from and including the effective date of the Change in Control transaction
up to and including the Trading Day prior to the related Change in Control Purchase Date.

     (b) The number of Make-Whole Shares will be determined by reference to the table below
and is based on the date which such Change in Control transaction becomes effective (the
“Change in Control Effective Date”) and the price paid per share of Common Stock in the
Change in Control (in the case of a change in control described in clause (ii) of the
definition thereof), or in the case of all other Changes in Control, the average of the
Closing Prices per share of Common Stock over the five Trading-Day period ending on the
Trading Day preceding the relevant Change in Control Effective Date (the “Stock Price”). If
holders of Common Stock receive only cash in the case of a Change in Control described in
clause (ii) of the definition thereof, the Stock Price shall be the Cash amount paid per
share of Common Stock. Otherwise, the Stock Price shall be the average of the Closing Prices
per share of Common Stock over the five Trading-Day period ending on the Trading Day
preceding the relevant Change in Control Effective Date.

     (c) The Stock Prices set forth in the first row of the table below will be adjusted as
of any date on which the Conversion Rate is adjusted. The adjusted Stock Prices will equal
the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction,
the numerator of which is the Conversion Rate immediately prior to the adjustment giving
rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so
adjusted. In addition, the number of Make-Whole Shares on the table below will be subject
to adjustment in the same manner as the Conversion Rate as set forth in Section 10.06
through Section 10.10.

     (d) If the exact Stock Prices and Change in Control Effective Dates are not set
forth in the table, then: (i) if the Stock Price is between two Stock Prices in the table
or the Change in Control Effective Date is between two Change in Control Effective Dates in
the table, the Make-Whole Shares issued upon conversion of the Notes will be determined by a
straight-line interpolation between the number of Make-Whole Shares set forth for the higher
and lower Stock Prices and the earlier and later Change in Control Effective Dates in the
table, based on a 365-day year, (ii) if the Stock Price is in excess of $32.00 per share,
subject to adjustment as set forth in Section 10.13(c), no Make-Whole Shares will be issued
upon conversion of the Notes; and (iii) if the Stock Price is less than $15.61 per share,
subject to adjustment as set forth in Section 10.13(c), no Make-Whole Shares will be issued
upon conversion of the Notes.

     (e) The Company may make such increases in the Conversion Rate, in addition to those
required by Sections 10.06, 10.07, 10.08, 10.09 and 10.10 as the Board of Directors
considers to be advisable to avoid or diminish any income tax to holders of Common Stock or
rights to purchase Common Stock resulting from any dividend or distribution of stock (or
rights to acquire stock) or from any event treated as such for income tax purposes.

     (f) To the extent permitted by applicable law, the Company from time to time may
increase the Conversion Rate by any amount for any period of time if the period is at least
twenty (20) days, the increase is irrevocable during the period and the Board of Directors
shall have made a determination that such increase would be in the best interests of the
Company, which determination shall be conclusive. Whenever the Conversion Rate is increased
pursuant to the preceding sentence, the Company shall mail to holders of record of the Notes
a notice of the increase at least fifteen (15) 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.

     Section 10.14 When Adjustment May Be Deferred. No adjustment in the Conversion Rate
need be made unless the adjustment would require an increase or decrease of at least 1% of the
Conversion Rate. Any adjustments that are less than 1% of the Conversion Rate shall be carried
forward and taken into account in determining any subsequent adjustment. In addition, the Company
shall make any carry forward adjustments not otherwise effected upon required purchase of the notes
pursuant to Section 3.01, and on April 5, 2013.

     Section 10.15 When No Adjustment Required.

     (a) No adjustment need be made for a transaction referred to in Section 10.06, Section
10.07, Section 10.08, Section 10.09 or Section 10.10 if Noteholders participate, without
conversion, in the transaction or event that would otherwise give rise to an adjustment
pursuant to such Section at the same time as holders of the Common Stock participate with
respect to such transaction or event and on the same terms as holders of the Common Stock
participate with respect to such transaction or event as if Noteholders, at such time, held
a number of shares of Common Stock equal to the Conversion Rate at such time.

52

 

     (b) No adjustment need be made for the issuance of Common Stock or any securities
convertible into or exchangeable for Common Stock or carrying the right to purchase Common
Stock or any such security.

     (c) No adjustment need be made for rights to purchase Common Stock pursuant to a
Company plan for reinvestment of dividends or interest.

     (d) No adjustment need be made for a change in the par value or no par value of the
Common Stock.

     (e) To the extent the Notes become convertible pursuant to this Article 10 into Cash,
no adjustment need be made thereafter as to the Cash. Interest will not accrue on the Cash.

     (f) The Conversion Rate shall not exceed 64.0615 shares per $1,000 principal amount of
the Notes on account of adjustments to the Conversion Rate pursuant to this Article 10,
subject to the adjustments set forth in Sections 10.06, 10.07, 10.08, 10.09 and 10.10 above.
Further, notwithstanding anything in this Article 10 (subject only to the provisions of the
second succeeding sentence), the conversion rate shall not exceed 103.4974 per $1,000
principal amount of the Notes (provided that if and to the extent that the Initial
Purchasers’ option to purchase additional Notes or additional 2011 Notes is exercised, the
maximum conversion rate shall be ratably decreased, such that in the case of a full exercise
by the Initial Purchasers of their option to purchase the Notes and the 2011 Notes, the
conversion rate shall not exceed 94.0886 per $1,000 principal amount of the Notes, other
than as a result of adjustments to the Conversion Rate in the manner set
forth in Sections 10.06, 10.07 and 10.08 (such limitations herein referred to as the
“Conversion Rate Cap”). The Company shall not take any action if, as a result of such
action, the adjustment to the Conversion Rate that would otherwise be made pursuant to the
provisions of 10.09 or 10.10 would be limited by the Conversion Rate Cap, unless such action
would not result in a violation of NASD Rule 4350 as such rule or successor to such rule may
be then in effect and interpreted by the NASD. If such action would not result in a
violation of NASD Rule 4350, then the Conversion Rate Cap shall not apply to such action
taken by the Company.

     Section 10.16 Notice of Adjustment. Whenever the Conversion Rate is adjusted, the
Company shall promptly mail to Noteholders a notice of the adjustment. The Company shall file with
the Trustee and the Conversion Agent such notice and a certificate from the Company’s independent
public accountants briefly stating the facts requiring the adjustment and the manner of computing
it. The certificate shall be conclusive evidence that the adjustment is correct. Neither the
Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such
certificate except to exhibit the same to any Holder desiring inspection thereof.

     Section 10.17 Notice of Certain Transactions. If (a) the Company takes any action
that would require an adjustment in the Conversion Rate pursuant to Section 10.06, 10.07, 10.08,
10.09 or 10.10 (unless no adjustment is to occur pursuant to Section 10.14 or Section 10.15), (b)
the Company takes any action that would require a supplemental indenture pursuant to Section

53

 

10.12,
or (c) there is a liquidation or dissolution of the Company, then the Company shall mail to
Noteholders and file with the Trustee and the Conversion Agent a notice stating the proposed
Ex-Dividend Date for a dividend or distribution or the proposed effective date of a subdivision,
combination, reclassification, consolidation, merger, binding share exchange, transfer, liquidation
or dissolution. The Company shall file and mail the notice at least 15 days before such date;
provided that if the Company elects to make a distribution described in Section 10.07, Section
10.08, or Section 10.09, and in the case of Section 10.08 or Section 10.09, that has a per share
value equal to more than 10% of the Closing Price per share of Common Stock on the day preceding
the declaration date for such distribution, the Company shall give notice to Holders at least 20
Trading Days prior to the Ex-dividend Date for such distribution. Failure to file or mail the
notice or any defect in it shall not affect the validity of the transaction.

     Section 10.18 Right of Holders to Convert. Notwithstanding any other provision in
this Indenture, the Holder of any Note shall have the right to convert its Note in accordance with
this Article 10 and paragraph 7 of the Notes and to bring an action for the enforcement of any such
right to convert, and such rights shall not be impaired or affected without the consent of such
Holder.

     Section 10.19 Company Determination Final. The Company shall be responsible for
making all calculations called for hereunder and under the Notes. These calculations include, but
are not limited to, Conversion Value, the
Conversion Date, the Volume Weighted Average Price, the Conversion Reference Period, the
Closing Price, the Conversion Price, the Required Cash Amount, the Applicable Conversion Rate and
the number of shares of Common Stock, if any, to be issued upon conversion of the Notes. The
Company shall make all these calculations in good faith and, absent manifest error, the Company’s
calculations will be final and binding on Noteholders. The Company shall provide a schedule of the
Company’s calculations to the Trustee, and the Trustee is entitled to rely upon the accuracy of the
Company’s calculations without independent verification.

     Section 10.20 Trustee’s Adjustment Disclaimer. The Trustee has no duty to determine
when an adjustment under this Article 10 should be made, how it should be made or what it should
be. The Trustee has no duty to determine whether a supplemental indenture under Section 10.12 need
be entered into or whether any provisions of any supplemental indenture are correct. The Trustee
shall not be accountable for and makes no representation as to the validity or value of any
securities or assets issued upon conversion of Notes. The Trustee shall not be responsible for the
Company’s failure to comply with this Article 10. Each Conversion Agent shall have the same
protection under this Section 10.20 as the Trustee.

     Section 10.21 Simultaneous Adjustments.

     (a) For purposes of Section 10.08, Section 10.06(a) and Section 10.07, any dividend or
distribution to which Section 10.08 is applicable that also includes shares of Common Stock,
or rights, options or warrants to subscribe for or purchase shares of Common Stock (or
both), shall be deemed instead to be (1) a dividend or distribution of the debt securities,
assets or shares of Capital Stock other than such shares of Common Stock or rights (and any
Conversion Rate adjustment required by Section 10.08 with respect to such dividend or
distribution shall then be made) immediately followed by (2)

54

 

a dividend or distribution of
such shares of Common Stock or such rights (and any further Conversion Rate adjustment
required by Section 10.06(a) and Section 10.07 with respect to such dividend or distribution
shall then be made), except any shares of Common Stock included in such dividend or
distribution shall not be deemed “outstanding at the close of business on the Business Day
immediately preceding such Ex-Dividend Date” within the meaning of Section 10.06(a).

     (b) The reclassification of the Common Stock into securities including securities other
than Common Stock (other than any reclassification upon an event to which Section 10.12
applies) shall be deemed to involve (a) a distribution of such securities other than the
Common Stock to all holders of Common Stock (and the effective date of such reclassification
shall be deemed to be the “Ex-Dividend Date” within the meaning of this Section 10.08), and
(b) a subdivision or combination, as the case may be, of the number of shares of Common
Stock outstanding immediately prior to such reclassification into the number of shares of
Common Stock outstanding immediately thereafter (and the effective date of such
reclassification shall be deemed to be “the day upon which such subdivision becomes
effective” or “the day upon which such combination becomes effective”, as the case may be,
and “the day upon which such subdivision or combination becomes effective” within the
meaning of Section 10.06(b)).

     Section 10.22 Successive Adjustments. After an adjustment to the Conversion Rate
under this Article 10, any subsequent event requiring an adjustment under this Article 10 shall
cause an adjustment to the Conversion Rate as so adjusted.

     Section 10.23 Rights Issued in Respect of Common Stock Issued Upon Conversion. Each
share of Common Stock issued upon conversion of Notes pursuant to this Article 10 shall be entitled
to receive the appropriate number of rights (“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 the Rights Agreement, dated as of August 12, 1998, between the Company
and BankBoston, N.A., as Rights Agent, or any successor shareholder rights agreement adopted by the
Company, as the same may be amended form time to time (in each case, a “Shareholders Rights Plan”).
If the Shareholders Rights Plan under which any Rights are issued provides that each share of
Common Stock issued upon conversion of the Notes at any time prior to the distribution of separate
certificates representing such Rights will be entitled to receive such Rights, there shall not be
any adjustment to the conversion privilege or Conversion Rate at any time prior to the distribution
of separate certificates representing such Rights. If, however, prior to any conversion the Rights
have separated from the Common Stock, the Conversion Rate shall be adjusted at the time of
separation as if the Company distributed to all Holders of the Common Stock, its assets, debt
securities or rights as described in Section 10.08 above, subject to readjustment in the event of
the expiration, termination or redemption of such Rights.

     Section 10.24 Withholding Taxes for Adjustments in Conversion Rate. The Company may,
at its option, set-off withholding taxes due with respect to Notes against payments of Cash and
Common Stock on the Notes to the extent required by law. In the case of any such set-off against
Common Stock delivered upon conversion of the Notes, such Common

55

 

Stock shall be valued based on the
arithmetic average of the Volume Weighted Average Price for each Trading Day in the relevant
Conversion Reference Period.

ARTICLE 11

PAYMENT OF INTEREST

     Section 11.01 Interest Payments. Interest on any Note that is payable, and is
punctually paid or duly provided for, on any applicable Interest Payment Date shall be paid to the
person in whose name that Note is registered at the Close of Business on the Regular Record Date
for such interest at the office or agency of the Company maintained for such purpose. Each
installment of interest payable in Cash on any Note shall be paid in same-day funds by transfer to
an account maintained by the payee located inside the United States, if the Trustee shall have
received proper wire transfer instructions from such payee not later than the related Regular
Record Date or, if no such instructions have been received by check drawn on a bank in the United
States mailed to the
payee at its address set forth on the Registrar’s books. In the case of a Global Note,
interest payable on any applicable payment date will be paid by wire transfer of same-day funds to
the Depositary, with respect to that portion of such Global Note held for its account by Cede & Co.
for the purpose of permitting such party to credit the interest received by it in respect of such
Global Note to the accounts of the beneficial owners thereof.

     Section 11.02 Defaulted Interest. Except as otherwise specified with respect to the
Note, any interest on any Note that is payable, but is not punctually paid or duly provided for,
within 30 days following any applicable payment date (herein called “Defaulted Interest”, which
term shall include any accrued and unpaid interest that has accrued on such defaulted amount in
accordance with paragraph 1 of the Notes), shall forthwith cease to be payable to the registered
Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause
(a) or (b) below.

     (a) The Company may elect to make payment of any Defaulted Interest to the persons in
whose names the Notes are registered at the Close of Business on a Special Record Date for
the payment of such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to
be paid on each Note and the date of the proposed payment (which shall not be less than 20
days after such notice is received by the Trustee), and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit on or prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the persons entitled to such Defaulted
Interest as in this clause provided. Thereupon the Trustee shall fix a special record date
for the payment of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment (the “Special Record Date”).
The Trustee shall promptly notify the Company of such Special Record Date and, in the name
and at the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage
prepaid, to each Holder of Notes at his address as it appears on the list of Noteholders
maintained pursuant to Section 2.05 not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and

56

 

the Special Record Date
therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the
persons in whose names the Notes are registered at the Close of Business on such Special
Record Date and shall no longer be payable pursuant to the following clause (b).

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

     Section 11.03 Interest Rights Preserved. Subject to the foregoing provisions of this
Article 11 and Section 2.06, each Note delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Notes.

ARTICLE 12

     Section 12.02 Noteholder Communications; Noteholder Actions.

     (a) The rights of Holders to communicate with other Holders with respect to the
Indenture or the Notes are as provided by the Trust Indenture Act, and the Company and the

312(b). Neither the Company nor the Trustee will be held accountable by reason of any
disclosure of information as to names and addresses of Holders made pursuant to the Trust
Indenture Act.

     (b) (i) Any request, demand, authorization, direction, notice, consent to amendment,
supplement or waiver or other action provided by this Indenture to be given or taken by a

Trustee. The fact and date of the execution of the instrument, or the authority of the
person executing it, may be proved in any manner that the Trustee deems sufficient.

  (ii) The Trustee may make reasonable rules for action by or at a meeting of
Holders, which will be binding on all the Holders.

57

 

     (c) Any act by the Holder of any Note binds that Holder and every subsequent Holder of
a Note that evidences the same debt as the Note of the acting Holder, even if no notation
thereof appears on the Note. Subject to paragraph (d), a Holder may revoke an act as to its
Notes, but only if the Trustee receives the notice of revocation before the date the
amendment or waiver or other consequence of the act becomes effective.

     (d) The Company may, but is not obligated to, fix a record date (which need not be
within the time limits otherwise prescribed by Trust Indenture Act Section 316(c)) for the
purpose of determining the Holders entitled to act with respect to any amendment or waiver
or in any other regard, except that during the continuance of an Event of Default, only the
Trustee may set a record date as to notices of default, any declaration or acceleration or
any other remedies or other consequences of the Event of Default. If a
record date is fixed, those Persons that were Holders at such record date and only
those Persons will be entitled to act, or to revoke any previous act, whether or not those
Persons continue to be Holders after the record date. No act will be valid or effective for
more than 90 days after the record date.

the Company, and no such indenture or loan or debt agreement may be used to interpret the
Indenture.

successor.

     Section 12.12 Duplicate Originals. The parties may sign any number of copies of the
Indenture. Each signed copy shall be an original, but all of them together represent the same
agreement.

Stockholders. No director, officer, employee, incorporator, member or stockholder of the
Company, as such, will have any liability for any obligations of the Company under the Notes or the

each interest payment date, commencing December 15, 2006.

          Interest on this Note will accrue from the most recent date to which interest has been paid on
this Note or the Note surrendered in exchange for this Note (or, if there is no existing default in
the payment of interest and if this Note is authenticated between a regular record date and the
next interest payment date, from such interest payment date) or, if no interest has been paid, from
the Issue Date. Interest will be computed in the basis of a 360-day year of twelve 30-day months.

          The Company will pay interest on overdue principal, premium, if any, and, to the extent

the Indenture (as defined below).

amount of the Notes.

	3.	 	Method of Payment.

time to time, the “Indenture”), between the Company and U.S. Bank National Association, as Trustee.
Capitalized terms used herein are used as defined in the Indenture unless otherwise indicated.
The terms of the Notes include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the
extent permitted by applicable law, in the event of any inconsistency between the terms of this
Note and the terms of the Indenture, the terms of the Indenture will control.

          The Notes are general unsecured obligations of the Company.

	6.	 	Repurchase at the Option of the Holder upon a Change in Control.

          At the option of the Holder and subject to the terms and conditions of the Indenture, the
Company shall become obligated to purchase the Notes held by such Holder on the date, at the
purchase price and as otherwise provided in the Indenture.

          Holders have the right to withdraw any Change in Control Purchase Notice by delivering to the
Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

          If Cash (and/or securities if permitted under the Indenture) sufficient to pay the Change in
Control Purchase Price of, together with any accrued and unpaid interest with respect to, all Notes
or portions thereof to be purchased as of the Change in Control Purchase Date is deposited with the
Paying Agent on or prior to the third Business Day following the Change in

 5

 

Control Purchase Date, interest shall cease to accrue on such Notes (or portions thereof)
immediately after such Change in Control Purchase Date whether or not the Note is delivered to the
Paying Agent, and the Holder thereof shall have no other rights as such (other than the right to
receive the Change in Control Purchase Price and accrued and unpaid interest upon surrender of such
Notes).

	7.	 	Conversion.

          A Holder of a Note may convert such Note into Cash and, to the extent the Conversion Value of
such Note is greater than $1,000, Cash, shares of Common Stock or a combination thereof, at the
option of the Company, as described in the Indenture before the Close of Business on the Business
Day immediately preceding Maturity Date, if at least one of the following conditions is satisfied:

          (a) during any calendar quarter commencing at any time after June 30, 2006, and only during
such calendar quarter, if the Closing Price of the Common Stock for at least 20 Trading Days in the
period of 30 consecutive Trading Days ending on the last Trading Day of the preceding calendar
quarter exceeds 130% of the Conversion Price per share of Common Stock on the last day of such
preceding calendar quarter (the “Conversion Trigger Price”);

          (b) during the five Business Day period immediately after any five consecutive Trading Day
period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes
for each day of such Measurement Period was less than 98% of the product of the Closing Price of
the Common Stock on such date and the Conversion Rate on such date;

          (c) the Company elects to distribute to all holders of Common Stock (i) rights or warrants
entitling all holders of the Common Stock to subscribe for or purchase, for a period expiring
within 60 days after the record date for such distribution, Common Stock at less than the average
of the Closing Prices of the Common Stock for the five consecutive Trading Days ending on the date
immediately preceding the first public announcement of the distribution, or (ii) Cash, debt
securities (or other evidence of Debt) or other assets (excluding dividends or distributions
described in Section 10.06 of the Indenture), which distribution, together with all other
distributions within the preceding twelve months, has a per share value exceeding 10% of the
average of the Closing Prices of the Common Stock for the five consecutive Trading Days ending on
the date immediately preceding the first public announcement of the distribution; or

          (d) if a Change of Control occurs or if the Company is a party to a consolidation, merger,
binding share exchange or transfer or lease of all or substantially all of the Company’s assets,
pursuant to which the Common Stock would be converted into Cash, securities or other assets; or

          (e) at any time on or after April 5, 2013 until the Close of Business on the Business Day
immediately preceding the Maturity Date.

          The Conversion Agent will determine on the Company’s behalf at the beginning of each calendar
quarter commencing at any time after June 30, 2006 through the calendar quarter ending March 31,
2013 whether the Notes are convertible as a result of the price of the

 6

 

Common Stock pursuant to clause (a) above and will notify the Company and the Trustee if the
Notes are so convertible.

          The Trustee shall have no obligation to determine the Trading Price of the Notes pursuant to
clause (b) above unless the Company has requested such determination; and the Company shall have no
obligation to make such request unless a Holder provides the Company with reasonable evidence that
the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the
Closing Price and the Conversion Rate. At such time, the Company shall instruct the Trustee to
determine the Trading Price beginning on the next Trading Day and on each successive Trading Day
until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the
product of the Closing Price and the Conversion Rate.

          If the Company makes a distribution described in subsection (c)(i) or (c)(ii), the Company
must notify Holders at least 20 Trading Days prior to the Ex-Dividend Date for such distribution.
Once the Company has given such notice, Holders may surrender their Notes for conversion at any
time until the earlier of the Close of Business on the Business Day prior to the Ex-Dividend Date
for such distribution or the Company’s announcement that such distribution will not take place,
even if the Notes are not convertible at that time.

          The Company will notify Noteholders and the Trustee as promptly as practicable following the
date on which the Company publicly announces any transaction described in clause (d) above, but in
no event less than 20 Trading Days prior to the anticipated effective date of such transaction.
Noteholders may surrender their Notes for conversion at any time after the date that is 15 Trading
Days prior to the anticipated effective date of such transaction until 35 Trading Days after the
actual date of such transaction (or, if such transaction also constitutes a Change in Control,
until the Change in Control Purchase date).

	8.	 	Defaults and Remedies.

          If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the Notes may declare all the Notes to be due
and payable, subject to certain limitations set forth in the Indenture. If a bankruptcy or
insolvency default with respect to the Company occurs and is continuing, the Notes automatically
become due and payable. Holders may not enforce the Indenture or the Notes except as provided in
the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount
of the Notes then outstanding may direct the Trustee in its exercise of remedies.

	9.	 	Amendment and Waiver.

          Subject to certain exceptions set forth in the Indenture, the Indenture and the Notes may be
amended, or default may be waived, with the consent of the Holders of a majority in principal
amount of the outstanding Notes. Without notice to or the consent of any Holder, the Company and
the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any
ambiguity, defect or inconsistency or if such amendment or supplement does not adversely affect the
interests of the Holders in any material respect.

	10.	 	Registered Form; Denominations; Transfer; Exchange.

          The Notes are in registered form without coupons in denominations of $1,000 principal amount
and integral multiples of $1,000. A Holder may register the transfer or exchange of Notes in
accordance with the Indenture. The Trustee may require a Holder to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. Pursuant to the Indenture, there are certain periods during which the Trustee will
not be required to issue, register the transfer of or exchange any Note or certain portions of a
Note.

	11.	 	Persons Deemed Owners.

          The registered Holder of this Note may be treated as the owner of this Note for all purposes.

	12.	 	Unclaimed Money or Notes.

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

	13.	 	Trustee Dealings with the Company.

          Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and
may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may
otherwise deal with the Company or its Affiliates with the same rights it would have if it were not
Trustee.

	14.	 	No Recourse Against Others.

          A director, officer, incorporator, agent, subsidiary, employee, member or stockholder, as
such, of the Company shall not have any liability for any obligations of the Company under the
Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or
their creation. By accepting a Note, each Noteholder waives and releases all such liability. The
waiver and release are part of the consideration for the issue of the Notes.

	15.	 	Authentication.

          This Note shall not be valid until an authorized officer of the Trustee manually signs the
Trustee’s Certificate of Authentication on the other side of this Note.
