ARTICLE 2

The Notes

     Section 2.01. Form, Dating and Denominations; Legends.

     (a) The Notes and the Trustee’s certificate of authentication will be substantially in the
form attached as Exhibit A. The terms and provisions contained in the form of the Note annexed as
Exhibit A constitute and are hereby expressly made a part of this Indenture. The Notes may have
notations, legends

12

 

or endorsements required by law, rules of or agreements with national securities exchanges to which
the Company is subject, or usage. Each Note will be dated the date of its authentication. The
Notes will be issuable only in denominations of $1,000 in principal amount and any integral
multiple thereof.

     (b) 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, conversions or issuances 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 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 (i) 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 (ii) impair, as between the Depositary and its Agent
Members, the operation of customary practices governing the exercise of the rights of a Holder of
any Note.

     (c) Book-Entry Provisions. The Company shall execute and the Trustee shall, in accordance
with this Section 2.01(c), authenticate and deliver initially one or more Global Notes that (i)
shall be registered in the name of the Depositary, (ii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary’s instructions and (iii) shall bear a legend substantially
to the effect set forth in Exhibit B.

     Section 2.02. Execution And Authentication. An Officer shall sign the Notes for the Company
by manual or facsimile signature. Typographic and other minor errors or defects in any such
facsimile signature shall not affect the validity or enforceability of any 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.

13

 

     A Note shall not be valid until an authorized signatory of the Trustee signs manually or by
facsimile 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 $175,000,000 (or up to $200,000,000 to the extent the Underwriters
exercise their over-allotment option under the Underwriting Agreement in full) 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 $175,000,000 (or $200,000,000 to the extent the Underwriters exercise their
over-allotment option under the Underwriting Agreement in full) except as provided in Section 2.07.

     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 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”).

14

 

     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 9).

     The Company hereby initially designates the Trustee as Paying Agent, Registrar, and Conversion
Agent, and each of the Corporate Trust Office of the Trustee and the office or agency of the
Trustee in the United States (located at 101 Barclay Street, New York, New York 10286, Attention:
Corporate Trust Administration), one 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 12:00 p.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 12:00 p.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.

     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 2.13, when a Note is

15

 

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 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 service charge,
except that the Company or the Registrar may require payment of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in relation thereto; provided that this
sentence shall not apply to any exchange pursuant to Section 2.10, Section 3.05, Section 10.03(b)
or Section 11.02(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.

     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

16

 

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 11, 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 12:00 p.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.

17

 

     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.

     (b) 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

18

 

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 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 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) 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.

ARTICLE 3

Fundamental Changes and Purchases Thereupon

     Section 3.01. Purchase at Option of Holders Upon a Fundamental Change.

     (a) Generally. If a Fundamental Change occurs at any time prior to the Maturity Date of the
Notes, then each Holder shall have the right, at such Holder’s option, to require the Company to

amount thereof, that is equal to $1,000 or a multiple of $1,000, on a date (the “Fundamental Change

19

 

“Fundamental Change Purchase Price”); provided that if a Fundamental Change Purchase Date is after a Regular Record
Date and on or prior to the Interest Payment Date related thereto, accrued and unpaid interest, if
any, for the full interest period to such Interest Payment Date and payable in respect of such
Interest Payment Date (irrespective of the actual Fundamental Change Purchase Date) shall be
payable to the Holders of record as of the corresponding Record Date and the Fundamental Change
Purchase Price shall be equal to 100% of the principal amount of the Notes to be purchased.

     (b) Purchases of Notes under this Section 3.01 shall be made, at the
option of the Holder thereof, upon:

immediately preceding the Fundamental Change Purchase Date, subject to extension to comply
with applicable law, of a duly completed notice (the “Fundamental Change Purchase Notice”)
in the form set forth on the reverse of the Notes or otherwise specifying:

     (A) if Certificated Notes have been issued, the certificate numbers of the
Notes to be delivered for purchase or, if Certificated Notes have not been
issued, the Fundamental Change Purchase Notice shall comply with the Applicable
Procedures;

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

     (C) that the Notes are to be purchased by the Company pursuant to the
applicable provisions of the Notes and this Article 3
of the Indenture; and

     (ii) delivery or book-entry transfer of the Notes to the Trustee (or other Paying
Agent appointed by the Company) (together with all necessary endorsements) on or before
the Business Day immediately preceding the Fundamental Change Purchase Date, subject to
extension to comply with applicable law, at the offices of the Trustee (or other Paying
Agent appointed by the Company), such delivery being a condition to receipt by the Holder
of the Fundamental Change Purchase Price therefor.

     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 promptly on the later of the Fundamental Change Purchase Date and the time of the book-entry
transfer or delivery of the Notes.

20

 

     Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee (or
other Paying Agent appointed by the Company) the Fundamental Change Purchase Notice contemplated by
this Section 3.01 shall have the right to withdraw such Fundamental Change
Purchase Notice at any time prior to the Close of Business on the Business Day immediately
preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the
Trustee (or other Paying Agent appointed by the Company) in accordance with Section 3.03 below.

     The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company
of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal
thereof.

     (c) Fundamental Change Company Notice. On or before the 20th calendar day after
the occurrence of a Fundamental Change, the Company shall provide to all Holders of record of the
Notes and the Trustee and Paying Agent a notice (the “Fundamental Change Company Notice”) of the
occurrence of such Fundamental Change and of the purchase right at the option of the Holders
arising as a result thereof. Such mailing shall be by first class mail. Simultaneously with
providing such Fundamental Change Company Notice, the Company shall publish a notice containing the
information included therein once in a newspaper of general circulation in The City of New York or
publish such information on the Company’s website or through such other public medium as the
Company may use at such time.

     Each Fundamental Change Company Notice shall specify:

     (i) the events causing a Fundamental Change;

     (ii) the date of the Fundamental Change;

Purchase Notice has been delivered by a Holder may be converted only if the Holder
withdraws the Fundamental Change Purchase Notice in accordance with Section 3.03; and

     (ix) the procedures that Holders must follow to require the Company to purchase their
Notes.

     No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ purchase rights or affect the validity of the proceedings for the purchase of the
Notes pursuant to this Section 3.01.

     (d) No Purchase During Events of Default. There shall be no purchase of any Notes pursuant to
this Section 3.01 if there has occurred and is continuing an Event of Default
(other than a default that is cured by the payment of the Fundamental Change Purchase Price of the
Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes
surrendered to it during the continuance of an Event of Default (other than a default that is cured
by the payment of the Fundamental Change Purchase Price with respect to such Notes) in which case,
upon such return, the Fundamental Change Purchase Notice with respect thereto shall be deemed to
have been withdrawn.

     Section 3.02 . Effect of Fundamental Change Purchase Notice. Upon receipt by the Paying
Agent of the Fundamental Change Purchase Notice specified in Section 3.01(a), the Holder of the
Note in respect of which such Fundamental Change Purchase Notice was given shall (unless such
Fundamental Change Purchase Notice is withdrawn as specified in the following two paragraphs)
thereafter be entitled to receive solely the Fundamental Change Purchase Price with respect to such
Note. Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of
funds by the Paying Agent, promptly on the later of (x) the Fundamental Change Purchase Date with
respect to such Note (provided the conditions in Section 3.01(a) have been satisfied) and (y) the
time of book-entry transfer or the 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 Repurchase
Notice has been given by the Holder thereof may not be converted pursuant to Article 11
hereof on or after the date of the delivery of such Change in Control Repurchase
Notice unless such Change in Control Repurchase Notice has first been validly withdrawn as
specified in this Section 3.02.

     Section 3.03 . Withdrawal of Fundamental Change Purchase Notice.

     (a) A Fundamental Change Purchase Notice may be withdrawn (in whole or in part) by means of a
written notice of withdrawal delivered to the

22

 

Paying Agent at any time prior to the Close of
Business on the Business Day immediately preceding the Fundamental Change Purchase Date,
specifying:

     (i) the name of the Holder;

     (ii) the principal amount of the Notes with respect to which such notice of
withdrawal is being submitted, which must be $1,000 or an integral multiple thereof;

     (iii) if Certificated Notes have been issued, the certificate numbers of the
withdrawn Notes; and

     (iv) the principal amount, if any, of Notes that remains subject to the original
Fundamental Change Purchase Notice, which portion must be in principal amounts of $1,000
or a multiple of $1,000;

provided that if Certificated Notes have not been issued, the notice must comply with the
Applicable Procedures.

     Section 3.04 . Deposit of Fundamental Change Purchase Price. Prior to 10:00 a.m. (local time
in The City of New York) on the Fundamental Change Purchase Date, subject to extension to comply
with applicable law, 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 herein) an amount of money (in immediately available funds
if deposited on such Business Day) sufficient to pay the Fundamental Change Purchase Price, of all
the Notes or portions thereof that are to be purchased as of the Fundamental Change Purchase Date.
The Company shall promptly notify the Trustee in writing of the amount of any deposits of cash made
pursuant to this Section 3.04. If the Paying Agent holds cash or securities sufficient to pay the
Fundamental Change Purchase Price of any Note for which a Fundamental Change Purchase Notice has
been tendered and not withdrawn in accordance with this Indenture as of the Business Day following
the Fundamental Change Purchase Date, then effective on the Fundamental Change Purchase Date, (a)
such Note shall cease to be outstanding and interest, if any, will cease to accrue thereon (whether
or not book-entry transfer of the Notes is made or whether or not the Notes are delivered to the
Paying Agent) and (b) all other rights of the Holder in respect thereof will terminate (other than
the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid
interest, if any, upon delivery or book-entry transfer of such Note, or interest payable on the
related Interest Payment Date, if the Fundamental Change Purchase Date occurs between the Record
Date and such Interest Payment Date, as applicable).

23

 

     Section 3.05 . Notes Purchased in Whole or in Part. Any Note that is to be purchased,
whether in whole or 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 Notes,
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 which is not purchased.

     Section 3.06 . Covenant to Comply With Securities Laws Upon Purchase of Notes. In connection
with any offer to purchase Notes under under Section 3.01, the Company shall to the
extent applicable (i) comply with Rule 13e-4 and Rule 14e-1 under the Exchange Act, (ii) file the
related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii)
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 in Section 3.01.

     Section 3.07 . Repayment to the Company. The Trustee and the Paying Agent shall return to
the Company any Cash that remains unclaimed, together with interest, if any, or dividends, if any,
thereon, held by them for the payment of the Fundamental Change Purchase Price as soon as
practicable following the date on which the Company is obligated to pay the Fundamental Change
Purchase Price to a Holder pursuant to the terms of this Indenture; provided that to the extent
that the aggregate amount of Cash deposited by the Company pursuant to Section 3.04 exceeds the
aggregate Fundamental Change Purchase Price of the Notes or portions thereof which the Company is
obligated to purchase as of the Fundamental Change Purchase Date, then as soon as practicable
following the Fundamental Change Purchase Date, the Trustee or the Paying Agent, as the case may
be, shall return any such excess to the Company.

fifteen (15) days prior to the mailing, in accordance with Section 4.04, of the notice of

less than all the Notes pursuant to Section 4.01 of this Indenture, the Trustee shall, within five
(5) Business Days after receiving the notice specified in Section 4.02, select the Notes to be
redeemed, on a pro rata basis or in accordance with any other method the Trustee considers
reasonably fair and appropriate. The Trustee shall make such selection from Notes then outstanding
and not already to be redeemed by virtue of having been previously called for redemption. The
Trustee may select for redemption portions of the principal amount of Notes that have denominations

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and

selected for redemption, except the unredeemed portion of the Notes being redeemed in part. The
Registrar need not issue, authenticate, register the transfer of or exchange any Note for a period
of fifteen (15) days before selecting, pursuant to this Section 4.03, the Notes to be redeemed.

     Section 4.04 . Notice of Redemption. (a) At least thirty (30) days but not more than sixty
(60) days before a Redemption Date, the Company shall mail, or cause to be mailed, by first-class

     (ii) the Redemption Price;

     (iii) the Conversion Rate and the Conversion Price;

     (iv) the names and addresses of the Paying Agent and the Conversion Agent;

     (vii) that Notes called for redemption must be surrendered to the Paying Agent to
collect the Redemption Price payable as herein provided upon redemption;

     (viii) that, unless there shall be a default in the payment of the Redemption Price

to accrue on and after the Redemption Date, such Notes will cease to be convertible after
the close of business on the Business Day immediately preceding the Redemption Date, and
all rights of the Holders of such Notes shall terminate on and after the Redemption Date,

herein provided upon redemption.

     (d) At the Company’s request, upon reasonable prior notice, the Trustee shall mail the notice
of redemption to each Holder whose Notes are to be redeemed in the Company’s name and at the
Company’s expense; provided, however, that the form and content of such notice shall be approved in
advance by the Company.

26

 

     Section 4.05 . Effect of Notice of Redemption. (a) Once notice of redemption is mailed,
Notes called for redemption become due and payable on the Redemption Date at the Redemption Price
and, on and after such Redemption Date (unless there shall be a Default in the payment of the
Redemption Price), such Notes shall cease to bear interest, and all rights of the Holders of such
Notes shall terminate, other than the right to receive, upon surrender of such Notes and in
accordance with the next sentence, the Redemption Price. Upon surrender to the Paying Agent of
Notes subject to redemption, such Notes shall be paid, to the Holder surrendering such Notes, at
the Redemption Price.

     (b) If any Note shall not be fully and duly paid upon surrender thereof for redemption, the
principal of, and accrued and unpaid interest on, such Note shall, until paid, bear interest from,
and including, the Redemption Date at the rate borne by such Note on the principal amount of such
Note, and such Note shall continue to be convertible pursuant to Article 11.

     (c) Notwithstanding anything herein to the contrary, there shall be no purchase of any Notes
pursuant to a redemption if the principal amount of the Notes has been accelerated, and such
acceleration has not been rescinded, on or prior to the relevant Redemption Date. The Paying Agent

of any such acceleration.

money, in funds immediately available on the Redemption Date, sufficient to pay the
Redemption Price of all Notes to be redeemed on that date. The Paying Agent shall return to the
Company, as soon as practicable, any money not required for that purpose.

     Section 4.07 . Notes Redeemed in Part. (a) Any Note to be submitted for redemption only in
part shall be delivered pursuant to Section 4.05 (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 its attorney duly authorized in writing). Upon
receipt of such Note together with any such required endorsements or transfer instruments, the
Company shall execute, and the Trustee shall, upon its receipt of a Company Order therefor,
authenticate and make available for delivery to the Holder of such Note without service charge, a
new Note or Notes, of any authorized denomination as requested by such Holder, of the same tenor
and in aggregate principal amount equal to the portion of such Note not submitted for redemption.

27

 

     (b) If any Note selected for partial redemption is converted in part, the principal of such
Note subject to redemption shall be reduced by the principal amount of such Note that is converted.

ARTICLE 5

Covenants

     Section 5.01 . 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 this 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 Fundamental Change Purchase Date, as the case may be, the Company will deposit with the
Trustee (or Paying Agent) money in immediately available funds sufficient to pay the amounts then
due; 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 this 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.

     (d) Payments in respect of the Notes represented by the Global Notes are to be made by wire
transfer of same-day funds to the Depositary for the purpose of permitting such party to credit the
payments received by it in respect of such Global Note to the accounts of the beneficial owners
thereof. With respect to Certificated Notes, the Company will make all payments 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.

     Section 5.02 . Maintenance of Office or Agency. The Company will maintain in the United
States, an office or agency where Notes may be

28

 

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 this 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 5.03 . 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; provided further that this
Section does not prohibit any transaction otherwise permitted by Section 6.01.

     Section 5.04 . Annual Reports. The Company shall deliver to the Trustee, within fifteen days
after the Company files the same with the Commission, copies of the Company’s annual reports 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 is required to file with
the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act. Reports, information
and documents filed by the Company with the Commission via the EDGAR system will be deemed filed
with the Trustee for purposes of this Section 5.04 as of the time that such reports, information
and documents are filed via EDGAR. Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute
constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers’ Certificates).

     Section 5.05 . 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 this Indenture and
that, based

29

 

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 5.06 . 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 5.07 . Notice of Defaults. The Trustee shall, within ninety (90) calendar days after
the Trustee has knowledge of the occurrence of a default, mail
to all Noteholders, as the names and addresses of such holders appear upon the Register,
notice of all defaults known to the Trustee, unless such defaults shall have been cured or waived
before the giving of such notice; provided that, except in the case of default in the payment of
the principal of, or interest (including Default Additional Interest, if any) on, any of the Notes,
the Trustee shall be protected in withholding such notice if and so long as the Trustee in good
faith determines that the withholding of such notice is in the interest of the Noteholders.

ARTICLE 6

     Section 6.01 . Company May Consolidate, Only on Certain Terms. The Company shall not
consolidate with or merge with or into, or convey, transfer or lease all or substantially all of
its properties and assets to, any Person, unless:

     (a) the resulting, surviving or transferee Person, if not the Company (the “Successor
Company”), is a Person organized and existing under the laws of the United States of America, any
state thereof or the District of Columbia, and the Successor Company (if not the Company itself)
expressly assumes, by a supplemental indenture, executed and delivered to the Trustee, in form reasonably

30

 

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

     (b) immediately after giving effect to such transaction, no Event of Default shall have

Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a
supplemental indenture is required in connection with such transaction, such supplemental
indenture, comply with this Article and that all conditions precedent herein provided for relating
to such transaction have been complied with, and the Trustee may rely upon such Officers’
Certificate and Opinion of Counsel as conclusive evidence that such transaction complies with this
Section 6.01.

     Section 6.02 . Successor Substituted. Upon any consolidation of the Company with, or merger
of the Company with or into, any other Person or any conveyance, transfer or lease of the
properties and assets of the Company substantially as an entirety in accordance with Section 6.01,
the Successor Company formed by such consolidation or into which the Company is merged or to which
such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein, and thereafter.

ARTICLE 7

Default and Remedies

     Section 7.01 . Events of Default.  An “Event of Default” occurs with

the Notes if:

     (a) The Company defaults in payment of the principal, Redemption Price or Fundamental Change

the Company to cure (or obtain a waiver of) such default within 60 days after receipt of such
notice;

     (g) The Company, or any Subsidiary, fails (i) to make any payment when due (whether by
scheduled maturity, required prepayment, acceleration, demand, or otherwise) in respect of any
Indebtedness or Guarantee having an aggregate principal amount (including undrawn committed or
available amounts and including amounts owing to all creditors under any combined or syndicated
credit arrangement) of more than $10,000,000, or (ii) to observe or perform any other agreement or
condition relating to any such Indebtedness or Guarantee or contained in any instrument or
agreement evidencing, securing or relating thereto, or any other event occurs, the effect of which
default or other event is to cause, or to permit the holder or holders of such Indebtedness or the
beneficiary or beneficiaries of such Guarantee (or a trustee or agent on behalf of such holder or
holders or beneficiary or beneficiaries) to cause, with the giving of notice if required, such
Indebtedness to be demanded or to become due or to be repurchased, prepaid, defeased or redeemed
(automatically or otherwise), or an offer to repurchase, prepay, defease or redeem such
Indebtedness to be made,

such other amount to the extent any of the Company’s obligations represented by the Indebtedness
(including any extensions, renewals or refinancings thereof) in at least $100,000,000 aggregate
principal amount are renegotiated, amended or supplemented with respect to a substantially similar
event of default resulting from a final judgment or orders for the payment of money, in which case
such other amount will be the lowest amount of any such obligations so renegotiated, amended or
supplemented, provided that such other amount shall not exceed $25,000,000, or (ii) any one or more
non-monetary final judgments that have, or could reasonably be excepted to have, individually or in
the aggregate, a material adverse effect and, in either case, (A) enforcement proceedings are
commenced

32

 

by any creditor upon such judgment or order, or (B) there is a period of ten consecutive
days during which a stay of enforcement of such judgment, by reason of a pending appeal or
otherwise, is not in effect;

     (i) The Company or any Subsidiary of the Company institutes or consents to the institution of
any proceeding under any Bankruptcy Law, or makes an assignment for the benefit of creditors; or

     Section 7.02 . Acceleration. If an Event of Default, other than a Bankruptcy Default, occurs
and is continuing under this 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 and unpaid 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, the principal of and accrued interest on the
Notes then outstanding will become immediately due and payable automatically without any
declaration or other act on the part of the Trustee or any Holder.

     Section 7.03 . Alternative Remedy for Failure to Comply with Reporting Obligations in the
Indenture and Trust Indenture Act. Notwithstanding any other
provision of this Article 7, if the
Company so elects not later than the occurrence of an Event of Default relating to the failure of
the Company to comply with Section 5.04 of this Indenture and/or for any failure to comply with the
requirements of Section 314(a)(1) of the Trust Indenture Act, the sole remedy for such Event of
Default will be (i) for the first 60 days after the occurrence of such an Event of Default, consist
exclusively of the right to receive additional interest (the “Default Additional Interest”) on the
Notes equal to 0.25% of the principal amount of the Notes and (ii) for the period from the 61st day
after the occurrence of such an Event of Default to the 120th day after the occurrence of such an
Event of Default, consist exclusively of the right to receive Default Additional Interest on the
Notes equal to 0.50% per annum of the principal amount of Notes. If the

33

 

Company elects to pay such
Default Additional Interest, such Default Additional Interest will be payable in the same manner
and on the same dates as the stated interest payable on the Notes under the terms of this
Indenture. If the Company so elects, such Default Additional Interest will be payable on all
outstanding Notes from and including the date on which such Event of Default first occurs to but
not including the 120th day thereafter (or such earlier date on which such Event of
Default relating to the Company’s reporting obligations shall have been cured or waived). On the
120th day after such Event of Default (if the Event of Default relating to the reporting
obligations is not cured or waived prior to such 120th day), such Default Additional
Interest shall cease to accrue and, if such Event of Default has not been cured or waived prior to
such
120th day, the Notes will be subject to acceleration as provided in this Article 7.
The provisions of this paragraph shall not affect the rights of Holders of Notes in the event of
the occurrence of any other Event of Default. If the Company does not elect to pay such Default
Additional Interest upon such an Event of Default in accordance with this paragraph, the Notes will
be subject to acceleration as provided in Section 7.02.

     In order to elect to pay such Default Additional Interest as the sole remedy during the first
120 days after the occurrence of an Event of Default relating to the Company’s failure to comply
with its reporting obligations in accordance with the immediately preceding paragraph, the Company
must notify all Holders of the Notes and the Trustee and Paying Agent of such election in writing
within ten Business Days of making such election. Upon the Company’s failure to give such notice or
pay such Default Additional Interest in the same manner and on the same dates as the stated
interest payable on the Notes under the terms of this Indenture, the Notes will be immediately
subject to acceleration as provided in Section 7.02.

     Section 7.04 . 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 this 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 7.05 . Waiver of Past Defaults. Except as otherwise provided in Section 7.08 and
Section 10.02(b), Holders of a majority in principal amount of the outstanding
Notes by written notice to the Company and to the Trustee may waive any past Default and rescind
and annul a declaration of acceleration with respect to such Default and its consequences (other
than an uncured default (x) in the payment of the principal amount with respect to any Note,
accrued and unpaid interest with

34

 

respect to any Note or the Fundamental Change Purchase Price with
respect to any Note, (y) in the payment or delivery of the consideration due upon conversion of the
Notes or (z) in respect of any provision that under this Indenture cannot be modified or amended
without the consent of the Holder of each outstanding Note affected) if:

	 	(i)	 	all existing Events of Default, other than the nonpayment of the principal
of 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.

Upon such waiver, the Default will cease to exist, and any Event of Default arising therefrom will
be deemed to have been cured, but no such waiver will extend to any subsequent or other Default or
impair any right consequent thereon.

     Section 7.06 . 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 this 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 7.07 . Limitation on Suits. A Holder may not institute any proceeding, judicial or
otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or
trustee, or for any other remedy under this 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 this 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

35

 

	 	(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 7.08 . Rights of Holders to Receive Payment. Notwithstanding anything to the
contrary, the right of a Holder of a Note to receive (x) payment of principal of or interest on its
Note on the Maturity Date or the relevant Interest Payment Date, as the case may be, (y) payment of
the Fundamental Change Purchase Price on the Fundamental Change Purchase Date and (z) delivery of
Common Stock upon conversion of such Note on the date specified in Section 11.02(b),
or to bring suit for the enforcement of any such payment or delivery, as the case may be,
on or after such respective dates, may not be impaired or affected without the consent of that
Holder.

     Section 7.09 . Collection Suit by Trustee. If an Event of Default in payment of principal or
interest specified in clause (a) or (b) of Section 7.01 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 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 7.10 . 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 this 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

36

 

Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding.

     Section 7.11 . 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;

     Third: to Holders for other amounts then due and unpaid in respect of the Notes,
ratably, without preference or priority of any kind, according to the amounts due and
payable in respect of the Notes; and

     Fourth: 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 7.12 . Restoration of Rights and Remedies. If the Trustee or any Holder has
instituted a proceeding to enforce any right or remedy under this 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 7.13 . Undertaking for Costs. In any suit for the enforcement of any right or remedy
under this Indenture or in any suit against the Trustee for any action taken or omitted by it as
Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an
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 (a) principal of or
interest on any Note on the respective due dates, (b) the Change of Control Purchase on the Change
of Control Repurchase Date, (c) Common Stock

37

 

due upon conversion of a Note or (d) a suit by Holders
of more than 10% in principal amount of the outstanding Notes.

     Section 7.14 . 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 7.15 . 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 8

The Trustee

     Section 8.01 . General. (a) Except during the continuance of an Event of Default,

(1) the Trustee undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture, and no implied covenants or obligations
shall be read into this Indenture against the Trustee; and

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

     (b) In case an Event of Default has occurred and is continuing, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture,

38

 

and use the same degree of care and
skill in their exercise, as a prudent person would exercise or use under the circumstances in the
conduct of his or her own affairs.

     (c) No provision of this 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,
except that

(1) this Subsection shall not be construed to limit the effect of Subsection (a)
of this Section 8.01;

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

(3) the Trustee shall not be liable with respect to any action taken or omitted
to be taken by it in good faith in accordance with the direction of the Holders
of a majority in principal amount of the outstanding Notes 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 this
Indenture with respect to the Notes; and

(4) no provision of this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur any financial liability in the performance of
any of its duties hereunder, or in the exercise of any of its rights or powers,
if it shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

     (d) Whether or not therein expressly so provided, every provision of this Indenture relating
to the conduct or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section 8.01.

through (d):

     (a) In the absence of bad faith on its part, the Trustee may conclusively 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

39

 

to the requirements of this 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, and, if the Trustee
shall determine to make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney at the sole cost of
the Company and shall incur no liability or additional liability of any kind by reason of such
inquiry or investigation.

     (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate

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

offered to the Trustee reasonable security or indemnity reasonably satisfactory to the Trustee
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

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 this Indenture.

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.

     (h) In no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but

40

 

not limited to, loss of profit) irrespective of whether the Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of action.

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

     (j) The rights, privileges, protections, immunities and benefits given to the Trustee,

enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and
other Person employed to act hereunder.

individuals and/or titles of officers authorized at such time to take specified actions pursuant to
this Indenture.

     Section 8.03 . Individual Rights of Trustee. The Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not 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.

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 (x) in
the payment of the principal of or interest on any Note (y) in the payment of the Fundamental
Change Purchase Price on the Fundamental Change Purchase Date or (z) in the delivery of Common
Stock upon conversion of such Note on the date specified in Section 11.02(b), 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 8.06 . Reports by Trustee to Holders. Within 60 days after each June 1, beginning
with June 1, 2008, the Trustee will mail to each Holder, as

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). The Company will promptly notify the Trustee in writing when the Notes are listed on any
stock exchange and of any delisting thereof.

     Section 8.07 . 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.

     (b) The Company will indemnify each of the Trustee or any predecessor Trustee and their agents
for, and to hold them harmless against, any and all loss, damage, claims, liability or expense,
including taxes (other than taxes based upon, measured by or determined by the income of the

trusts hereunder, including the costs and expenses of defending itself against any claim (whether
asserted by the Company, or any Holder or any other Person) or liability in connection with the
exercise or performance of any of its powers or duties hereunder, or in connection with enforcing
the provisions of this Section, except to the extent that such loss, damage, claim, liability or
expense is due to its own negligence or bad faith.

     (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.

     (d) The provisions of this Section 8.07 shall survive the termination of this Indenture.

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 8.10 or in the circumstances
described in Trust Indenture Act Section 310(b), any Holder that satisfies the
requirements of Trust Indenture Act Section

42

 

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 8.10; (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, at the Company’s expense, 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 8.07(c), (ii) the
resignation or removal of the retiring Trustee will become effective, and (iii) the successor
Trustee will have all the rights, powers and duties of the Trustee under this 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 8.07 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 8.09 . Successor Trustee by Merger. If the Trustee consolidates with, merges or
converts into, or transfers all or substantially all of its corporate

43

 

trust business 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 this Indenture.

     Section 8.10 . Eligibility. This 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 $50,000,000 as set forth in its most recent published annual report of condition.

     If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust
Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the
manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture;
provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the
Trust Indenture Act any indenture or indentures under which other securities or certificates of
interest or participation in other securities of the Company are outstanding if the requirements
for such exclusion set forth in Section 310(b)(1) of the Trust Indenture Act are met.

     Section 8.11 . 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 9.

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

ARTICLE 9

Discharge

     Section 9.01 . Satisfaction and Discharge of this Indenture. (a) This Indenture shall cease

become due and payable on the Maturity Date, on any Fundamental Change Purchase Date in connection
with any purchase upon the occurrence of a Fundamental Change or on a Redemption Date or (iii) all

Paying Agent is not the Company or any of its Affiliates) or the Conversion Agent Cash in respect
of such payment or Common Stock in respect of any such conversion on the Maturity Date, the
Fundamental Change Purchase Date, the Redemption Date or the date such conversion is to be settled,
as the case may be; provided that, in all cases, the Company shall pay 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 or delivery, as the case may be, 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

this Indenture have been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Company to the Trustee under Section 8.07 shall survive and, if money shall have been deposited

2.04, Section 2.05, Section 2.06, Section 2.07, Section 2.12, Section 3.01, Article 6, Article 11
and this Article 9, shall survive and the Company shall be required to make all payments and

satisfaction and discharge until the Notes have been paid in full.

     Section 9.02 . Application of Trust Money. Subject to the provisions of Section 9.03, the
Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money, Common

and the Notes to the payment of the principal amount of (including the relevant Fundamental Change
Purchase Price or Redemption Price, as applicable) and interest on the Notes or delivery of the

deliver, as the case may be, to the Company upon request any excess money, Common Stock or other
consideration (x) paid or delivered to them pursuant to Section 9.01 and (y) held by them at any
time.

     The Trustee and each Paying Agent shall also pay or deliver, as the case may be, to the
Company upon request any money, Common Stock or other consideration held by them for the payment of
the principal amount of (including the relevant Fundamental Change Purchase Price or Redemption
Price, as applicable) and interest on, or the amount due in connection with any conversion of, the
Notes that remains unclaimed for two years after a right to such money, Common Stock or other
consideration has matured (which maturity shall occur, for the avoidance of doubt, on the Maturity
Date, the Fundamental Change Purchase Date, the Redemption Date or the date specified in Section
11.02(b), as the case may be); provided that the Trustee or such Paying Agent, before being
required to make any such payment or delivery, may at the expense of the Company cause to be mailed
to each Holder entitled to such money, Common Stock or other consideration or publish in a
newspaper of general circulation in the City of New York notice that such money, Common Stock or
other consideration 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 or portion of
such money, Common Stock or other consideration then remaining will be repaid or re-delivered to
the Company. After payment or delivery, as the case may be, to the Company, Holders entitled to
such money, Common Stock or other consideration must look to the Company for payment or delivery as
general creditors unless an applicable abandoned property law designates another Person.

     Section 9.04 . Reinstatement. If the Trustee or any Paying Agent is unable to apply any
money, Common Stock or other consideration in accordance with Section 9.02 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 payment or delivery, as the
case may be, had occurred pursuant to Section 9.01 until such time as the Trustee or such Paying
Agent is permitted to apply all such money in accordance with Section 9.02; provided that if the
Company has made any payment of the principal amount of (including the relevant Fundamental Change
Purchase Price or Redemption Price, as applicable) or interest on, or the amount due in connection
with any conversion of, the 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 or
delivery from the money, Common Stock or other consideration held by the Trustee or such Paying
Agent.

     Section 10.02 . Waivers; Amendments With Consent of Holders. (a) Except as otherwise
provided in Section 7.08 or paragraph (b), the Company and the Trustee may amend this Indenture and
the Notes with the written consent of the Holders of at least 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, on behalf of the Holders of such Notes waive any existing or
past default under this Indenture and its consequences, except an uncured default (i) in the

the Fundamental Change Purchase Price with respect to any Note, (iii) in the payment or delivery of
the consideration due upon conversion of the Notes or (iv) in respect of any provision that under

47

 

     (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, or interest payment on any Note, or reduce the
Fundamental Change Purchase Price on any Note;

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

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 10.04 . 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
this 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 this Indenture.

pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

     Section 10.06 . 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

ARTICLE 11

Conversion

     Section 11.01 . Conversion Privilege. (a) Subject to and upon compliance with the provisions
of this Article 11, a Noteholder shall have the right, at such Noteholder’s option, to convert all
or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple
thereof) of such Noteholder’s Notes at any time on or prior to the Close of Business on the
Business Day immediately preceding the Maturity Date at a conversion rate (the “Conversion

49

 

Rate”) equivalent to 30.6279 shares of Common Stock per $1,000 principal amount of Notes,
subject to adjustment as set forth in this Article 11. Upon conversion of any Notes, the Company
shall deliver to the converting Noteholder shares of Common Stock and cash in lieu of fractional
shares as described in this Article 11 (the Company’s obligation to deliver such consideration
being herein called the “Conversion Obligation”).

     Section 11.02 . Conversion Procedures; Conversion Settlement. (a) 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 or facsimile of the Conversion Notice, and
deliver such Conversion Notice to the Conversion Agent, (2) surrender the Note to the Conversion
Agent, (3) if required, furnish appropriate endorsements and transfer documents, (4) if required,
pay all transfer or similar taxes and (5) if required, pay Cash equal to the amount of interest due
on the next Interest Payment Date for such Note. If a Noteholder holds a beneficial interest in a
Global Note, to convert such beneficial interest, such Noteholder must comply with the requirements
(4) and (5) as set forth in the immediately preceding sentence and comply with the applicable
procedures of the Depositary for converting a beneficial interest in a Global Note. The date on
which a Noteholder satisfies the requirements set forth in the first sentence of this Section
11.02(a) (in the case of a Certificated Note) or, as the case may be, the second sentence of this
Section 11.02(a) (in the case of a Global Note or a beneficial interest therein) is referred to in
this Indenture as the “Conversion Date.” The Conversion Agent shall, within one (1) Business Day
of any Conversion Date, provide notice to the Company, as set forth in Section 13.03, of the
occurrence of such Conversion Date.

     (b) The Company shall satisfy the Conversion Obligation by delivering solely shares of Common
Stock (except for any Cash in lieu of fractional shares) as soon as practicable but in any event
within three Business Days of the relevant Conversion Date.

     The number of shares of Common Stock due upon conversion of Notes shall be equal to (i) (A)
the aggregate principal amount of Notes to be converted divided by (B) 1,000 multiplied by (ii) the
Applicable Conversion Rate in effect on the relevant Conversion Date (provided that the Company
shall deliver Cash in lieu of fractional shares as described in Section 11.03).

     (c) A Holder receiving Common Stock upon conversion shall not be entitled to any rights as a
holder of Common Stock, including, among other things, the right to vote and receive dividends and
notices of stockholder meetings, until the Close of Business on the Conversion Date (on which date
such Holder shall be deemed to be the Holder of record of a number of shares of Common Stock to
which such Holder is entitled).

50

 

     (d) 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 11. 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 shares of Common Stock received by
the Noteholder upon conversion. Delivery to the Noteholder of such shares of Common Stock shall
thus be deemed to satisfy (1) the Company’s obligation to pay the principal amount of a Note, and
(2) the Company’s obligation to pay any 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.

     (e) Notwithstanding Section 11.02(d), if Notes are converted after a Regular Record Date but
prior to the next succeeding Interest Payment Date, Holders of such notes at the Close of Business
on such Record Date will receive the interest payable on such Notes on the corresponding Interest
Payment Date notwithstanding the conversion. Such Notes, upon surrender for conversion, must be
accompanied by Cash equal to the amount of interest payable on such Interest Payment Date on the
Notes so converted; provided that no such payment need be made (1) if the Company has specified a
Fundamental Change Purchase Date that is after a Regular Record Date but on or prior to the next
succeeding Interest Payment Date, (2) with respect to any notes converted after the Regular Record
Date immediately preceding the Maturity Date, (3) if the Company has specified a Redemption Date
that is after a Regular Record Date but on or prior to the next succeeding Interest Payment Date or
(4) to the extent of any Defaulted Interest that exists at the time of conversion with respect to
such Note.

     (f) If a Noteholder converts more than one Note at the same time, the number of shares of
Common Stock and the amount of Cash in lieu of fractional shares due upon conversion shall be
determined based on the total principal amount of the Notes converted.

     (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 11.03 . Fractional Shares. The Company will not issue a fractional share of Common
Stock upon conversion of a Note. Instead, the Company shall pay Cash in lieu of fractional shares
based on the Last Reported Sale Price of Common Stock on the Trading Day prior to the applicable
Conversion Date.

     Section 11.04 . Taxes on Conversion. If a Holder converts a Note, the Company shall pay any
documentary, stamp or similar issue or transfer tax due on

51

 

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 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 Common Stock is to be delivered in a name other
than the Holder’s name.

     Section 11.05 . Company to Provide Common Stock. The Company shall, from time to time as may
be necessary, reserve out of its authorized but unissued shares of Common Stock a sufficient number
of shares of Common Stock to permit the delivery in respect of all outstanding Notes of the number
of shares of Common Stock due upon conversion.

     Any shares of Common Stock delivered 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 conversion of Notes, if any, and shall 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 Common Stock is then listed or quoted.

     In addition, if any shares of Common Stock that 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.

     Section 11.06 . Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from
time to time by the Company if any of the following events occurs.

     (a) If the Company, at any time or from time to time while any of the Notes are outstanding,
exclusively issues shares of Common Stock as a dividend or distribution on shares of Common Stock,
or if the Company effects a share split or share combination, then the Conversion Rate will be
adjusted based on the following formula:

where

52

 

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the record date of
such dividend or distribution, or the effective date of such share split or share
combination, as applicable;
	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect immediately after the record date of such
dividend or distribution or such share split or share combination, as applicable;
	 
	 

	 	OS0
	 	=
	 	the number of shares of Common Stock outstanding immediately prior to
such record date or effective date; and
	 
	 

	 	OS1
	 	=
	 	the number of shares of Common Stock that would be outstanding
immediately after, and solely as a result of, such dividend, distribution, share
split or share combination.

If any dividend or distribution of the type described in this Section 11.06(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.

     (b) If the Company, at any time or from time to time while any of the Notes are outstanding,
issues to all or substantially all holders of Common Stock any rights or warrants entitling them
for a period of not more than 60 calendar days to subscribe for or purchase shares of Common Stock,
at a price per share less than the average of the Last Reported Sale Prices of Common Stock for the
10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of
announcement of such issuance, the Conversion Rate shall be adjusted based on the following
formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the record date for
such issuance;
	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect immediately after the record date for such
issuance;
	 
	 

	 	OS0
	 	=
	 	the number of shares of Common Stock outstanding immediately prior to
such record date;
	 
	 

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

53

 

	 	 	 	 	 	 	 
	 

	 	Y
	 	=
	 	the number of shares of Common Stock equal to the aggregate price payable
to exercise such rights or warrants divided by the average of the Last Reported Sale
Prices of Common Stock over the 10 consecutive Trading Day period ending on the
Trading Day immediately preceding the date of announcement of the issuance of such
rights or warrants.

     To the extent such rights or warrants are not exercised prior to their expiration or
termination, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in
effect had the adjustments made upon the issuance of such rights or warrants been made on the basis
of the delivery of only the number of shares of Common Stock actually delivered. If such rights or
warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate
which would then be in effect if the record date for such rights or warrants had not been fixed.
In determining whether any rights or warrants entitle the holders to subscribe for or purchase
shares of Common Stock at less than the average of the Last Reported Sale Prices of Common Stock
for the 10 consecutive Trading Day period ending on the Business Day immediately preceding the date
of announcement of such issuance, 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 or
warrants and the value of such consideration, if other than cash, as shall be determined in good
faith by the Board of Directors.

     (c) If the Company, at any time or from time to time while the Notes are outstanding,
distributes shares of any class of Capital Stock of the Company, evidences of indebtedness or other
assets or property of the Company to all or substantially all holders of Common Stock, excluding:

     (i) dividends or distributions as to which Section 11.06(a) applies;

     (ii) rights or warrants as to which Section 11.06(b) applies;

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

     (iv) Spin-Offs (as defined below) to which the provisions set forth below in this
clause 11.06(c) shall apply;

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

54

 

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the record date for
such distribution;
	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect immediately after the record date for such
distribution;
	 
	 

	 	SP0
	 	=
	 	the average of the Last Reported Sale Prices of Common Stock over the 10
consecutive Trading Day period ending on the Trading Day immediately preceding the
Ex-Dividend Date for such distribution; and
	 
	 

	 	FMV
	 	=
	 	the Fair Market Value (as determined by the Board of Directors) of the
shares of Capital Stock, evidences of indebtedness, assets, property, rights or
warrants distributed with respect to each outstanding share of Common Stock on the
Ex-Dividend Date for such distribution.

     If the Board of Directors determines the Fair Market Value of any distribution for purposes of
this Section 11.06(c) by reference to the actual or when issued trading market for any securities,
it must in doing so consider the prices in such market over the same period used in computing the
average of the Last Reported Sale Prices of Common Stock.

     With respect to an adjustment pursuant to this Section 11.06(c) where there has been a payment
of a dividend or other distribution on Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary of the Company or other business
unit (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the end of the
Valuation Period (as defined below);
	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect immediately after the end of the Valuation
Period;
	 
	 

	 	FMV0
	 	=
	 	 the average of the Last Reported Sale Prices of the Capital Stock or
similar equity interest distributed to holders of Common Stock applicable to one
share of Common Stock over the first ten consecutive Trading Day period after, and

55

 

	 	 	 	 	 	 	 
	 

	 	 	 	 	 	including, the effective date of the Spin-Off (the “Valuation Period”);
and
	 
	 

	 	MP0
	 	=
	 	the average of the Last Reported Sale Prices of Common Stock over the
Valuation Period.

     The adjustment to the Conversion Rate under the preceding paragraph will occur on the last day
of the Valuation Period; provided that in respect of any conversion during the Valuation Period,
references within this Section 11.06(c) to “10 Trading Days” shall be deemed replaced with such
lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the
Conversion Date in determining the applicable Conversion Rate.

     (d) If any cash dividend or other distribution is made to all or substantially all holders of
Common Stock, the Conversion Rate shall be adjusted based on the following formula:

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the record date for
such dividend or distribution;
	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect immediately after the record date for such
dividend or distribution;
	 
	 

	 	SP0
	 	=
	 	the Last Reported Sale Price of a share of Common Stock on the Trading
Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and
	 
	 

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

     (e) If the Company or any Subsidiary of the Company makes a payment in respect of a tender
offer or exchange offer for Common Stock, to the extent that the cash and value of any other
consideration included in the payment per share of Common Stock exceeds the Last Reported Sale
Price per share of Common Stock on the Trading Day next succeeding the last date on which tenders
or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be
increased based on the following formula:

56

 

where

	 	 	 	 	 	 	 
	 

	 	CR0
	 	=
	 	the Conversion Rate in effect immediately prior to the effective date of
the adjustment;
	 
	 

	 	CR1
	 	=
	 	the Conversion Rate in effect on the effective date of the adjustment;
	 
	 

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

	 	SP1
	 	=
	 	the average of the Last Reported Sale Prices of Common Stock over the 10
consecutive Trading Day period commencing on, and including, the Trading Day next
succeeding the date such tender or exchange offer expires;
	 
	 

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

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

The adjustment to the Conversion Rate under this Section 11.06(e) shall occur at the Close of
Business on the tenth Trading Day from, and including, the Trading Day next succeeding the date
such tender or exchange offer expires; provided that in respect of any conversion within the 10
Trading Days immediately following, and including, the date the tender or exchange offer expires,
references within this Section 11.06(e) to “10 Trading Days” shall be deemed replaced with such
lesser number of Trading Days as have elapsed between the expiration date of such tender or
exchange offer and the Conversion Date in determining the applicable Conversion Rate.

     If the Company is obligated to purchase shares pursuant to any such tender or exchange offer,
but the Company is permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate
that would then be in effect if such tender or exchange had not been made.

     (f) All required calculations will be made to the nearest cent or 1/10,000th of a share of
Common Stock, as the case may be.

57

 

     (g) For purposes of this Section 11.06, “record date” shall mean, with respect to any
dividend, distribution or other transaction or event in which the holders of Common Stock have the
right to receive any cash, securities or other property or in which Common Stock (or other
applicable security) is exchanged for or converted into any combination of cash, securities or
other property, the date fixed for determination of stockholders entitled to receive such cash,
securities or other property (whether such date is fixed by the Board of Directors or by statute,
contract or otherwise).

     (h) The Company from time to time may, in its sole discretion, increase the Conversion Rate by
any amount for a period of at least 20 Business Days if 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 this Section 11.06(h),
the Company shall mail to Holders of record of the Notes a notice of the increase at least 15
calendar 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.

     (i) The Company may (but is not required to) make such increases in the Conversion Rate, in
addition to any adjustments required by Section 11.06(a), 11.06(b), 11.06(c), 11.06(d), 11.06(e) or
11.06(h), as the Board of Directors considers to be advisable to avoid or diminish income tax to
holders of Common Stock or rights to purchase shares of Common Stock in connection with any
dividend or distribution of shares (or rights to acquire shares) or from any event treated as such
for income tax purposes.

     (j) All calculations under this Section 11.06 shall be made by the Company. No adjustment
shall be made for the Company’s issuance of Common Stock or securities convertible into or
exchangeable for shares of Common Stock or rights to purchase Common Stock or convertible or
exchangeable securities, other than as provided in this Section 11.06.

     (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent an Officers’ Certificate setting forth the
Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Unless and until the Trustee has received such Officers’ Certificate, the Trustee
shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume
without inquiry that the last Conversion Rate of which it has knowledge is still in effect.
Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment
of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each
adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate
to each Noteholder at such Holder’s last address appearing on the list of Noteholders

provided for in Section 2.06, within 20 days after execution of the related Officers’
Certificate. Failure to deliver such notice shall not affect the legality or validity of any such
adjustment.

     (l) For purposes of this Section 11.06, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company so long as the Company
does not pay any dividend or make any distribution on shares of Common Stock held in the treasury
of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu
of fractions of shares of Common Stock.

     (m) No adjustment to the Conversion Rate shall be made pursuant to this Section 11.06 if the
Holders of the Notes may participate without conversion of their Notes in the transaction that
would otherwise give rise to an adjustment pursuant to this Section 11.06 at the same time as
holders of Common Stock and on the same terms as holders of Common Stock as if the Holders of the
Notes held a number of shares of Common Stock equal to the Conversion Rate multiplied by the
principal amount (expressed in thousands) of the Notes held by the Holders.

     (n) Notwithstanding the foregoing, if the application of the foregoing formulas would result
in a decrease in the Conversion Rate (other than as a result of a share split or share
combination), no adjustment to the Conversion Rate shall be made.

     (o) Notwithstanding anything to the contrary in this Article 11, no adjustment to the
Conversion Rate shall be made:

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

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

     (iii) upon the issuance of any shares of Common Stock pursuant to any option,
warrant, right or exercisable, exchangeable or convertible security not described in (ii)
above outstanding as of the date the Notes were first issued;

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

59

 

     (v) for accrued and unpaid interest.

     Section 11.07. Adjustments of Average Prices. Whenever a provision of this Indenture
requires the calculation of an average of Last Reported Sale Prices over a span of multiple days,
the Company shall make appropriate adjustments to account for any adjustment to the Conversion Rate
that becomes effective, or any event requiring an adjustment to the Conversion Rate that becomes
effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date
of the event occurs, at any time during the period from which the average is to be calculated.

     Section 11.08. Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.
If any of the following events occur:

     (i) any recapitalization, reclassification or change of shares of Common Stock
issuable upon conversion of the Notes (other than a change as a result of a subdivision or
combination);

     (ii) any consolidation, merger or combination to which the Company is a party other
than a merger in which the Company is the continuing corporation and which does not result
in any recapitalization, reclassification of, or change (other than 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) in outstanding shares of Common Stock or any statutory share
exchange; or

     (iii) any sale, lease or other transfer of all or substantially all of the
consolidated properties and assets of the Company and its Subsidiaries to any other Person
or any statutory share exchange;

in each case of clauses (i) — (iii) as a result of which holders of Common Stock shall be entitled
to receive stock, other securities or other property or assets (including cash or any combination
of the foregoing) with respect to or in exchange for such Common Stock, then at the effective time
of such transaction, 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) providing that each $1,000
principal amount of Notes shall be convertible into the kind and amount of shares of stock, other
securities or other property or assets (including cash or any combination thereof) receivable upon
such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease,
transfer or exchange by a holder of a number of shares of Common Stock equal to the Conversion Rate
immediately prior to such recapitalization, reclassification, change, consolidation, merger,
combination, sale, lease, transfer or exchange (the “Reference Property”). If the transaction

60

 

causes Common Stock to be converted into the right to receive more than a single type of
consideration (determined based in part upon any from of stockholder
election), the Reference Property into which the Notes will be convertible shall be deemed to be
the weighted average of the types and amounts of consideration actually received by the holders of
Common Stock. The Company shall not become a party to any such transaction unless its terms are
consistent with this Section 11.08. 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 11. If, in the case of any such recapitalization, reclassification, change, consolidation,
merger, combination, sale, lease, transfer or exchange, the Reference Property receivable thereupon
by a holder of Common Stock includes shares of stock, other securities or other property or assets
(including cash or any combination thereof) of a corporation other than the successor or purchasing
corporation, as the case may be, in such reclassification, change, consolidation, merger,
combination, sale, lease, transfer or exchange, then such supplemental indenture shall also be
executed by such other corporation and shall contain such additional provisions to protect the
interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary
by reason of the foregoing.

     The Company shall cause notice of the execution of such supplemental indenture to be mailed to
each Holder, at the address of such Holder 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 shall similarly apply to successive reclassifications, changes, consolidations, mergers,
combinations, sales and conveyances. If this Section 11.08 applies to any event or occurrence,
Section 11.06 shall not apply.

     Section 11.09. Adjustment to Conversion Rate Upon a Make-Whole Fundamental Change. (a) If,
after the date hereof, a Fundamental Change described in clause (1) or (2) of the definition
thereof (determined after giving effect to any exceptions or exclusions to such definition, other
than the proviso in clause (2) of the definition thereof, and excluding a Fundamental Change that
would not result in a purchase right as a result of the paragraph immediately following the
definition of Fundamental Change, a “Make-Whole Fundamental Change”) occurs and a Holder elects to
convert its Notes in connection with such Make-Whole Fundamental Change, the Company will, under
certain circumstances, increase the Applicable Conversion Rate for the Notes so surrendered for
conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described
in this Section 11.09. A conversion of Notes will be deemed for these purposes to be “in
connection with” a Make-

61

 

Whole Fundamental Change if the notice of conversion of the Notes is
received by the Conversion Agent from, and including, the Effective Date of the Make-Whole
Fundamental Change up to, and including, the Business Day immediately prior to the related
Fundamental Change Repurchase Date (or, in the case of an event that would have been a Fundamental
Change but for the proviso in clause (2) of the definition thereof, the 35th Trading Day immediately following the Effective Date
of such Make-Whole Fundamental Change).

     On or before the 5th day after the occurrence of a Make-Whole Fundamental Change that does not
also constitute a Fundamental Change, the Company will mail to the Trustee and to all Holders at
their addresses shown in the Register of the Registrar, and to beneficial owners as required by
applicable law, notice indicating that a Make-Whole Fundamental Change has occurred.

     (b) The number of Additional Shares will be determined by reference to the table below and is
based on the date which such Make-Whole Fundamental Change transaction becomes effective (the
"Effective Date”) and the price (the “Stock Price”) paid per share of Common Stock in the
Make-Whole Fundamental Change, which shall be deemed to be: (i) in the case of a Make-Whole
Fundamental Change described in clause (2) of the definition of Fundamental Change in which holders
of Common Stock receive only Cash, the per share price paid to Holders of Common Stock in such
transaction, or (ii) in the case of any other Make-Whole Fundamental Change, the average of the
Last Reported Sale Prices per share of Common Stock over the five Trading-Day period ending on the
Trading Day immediately preceding the Effective Date.

     (c) The Stock Prices set forth in the first column of the table below will be adjusted as of
any date on which the Applicable Conversion Rate is adjusted. The adjusted Stock Prices will equal
the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of
which is the Applicable Conversion Rate immediately prior to the adjustment giving rise to the
Stock Price adjustment, and the denominator of which is the Applicable Conversion Rate as so
adjusted. In addition, the number of Additional Shares will be subject to adjustment in the same
manner as the Applicable Conversion Rate as set forth in Section 11.06.

     (d) If the exact Stock Price and Effective Date is not set forth in the table, then (i) if the
Stock Price is between two Stock Prices in the table above or the Effective Date is between two
Effective Dates in the table above, the
Additional Shares issued upon conversion of the Notes will be determined by a straight-line
interpolation between the number of Additional Shares set forth for the higher and lower Stock
Prices and/or the earlier and later Effective Dates in the table, as applicable, based on a 365-day
year, (ii) if the Stock Price is greater than $130.00 per share of Common Stock (subject to
adjustment as set forth in Section 11.09(c)), no Additional Shares will be issued upon conversion
of the Notes; and (iii) if the Stock Price is less than $26.12 per share of Common Stock (subject
to adjustment as set forth in Section 11.09(c)), no Additional Shares will be issued upon
conversion of the Notes.

     (e) Notwithstanding anything in this Article 11 to the contrary, the Applicable Conversion
Rate shall not exceed 38.2848 per $1,000 principal amount of Notes, other than on account of
adjustments to the Conversion Rate in the manner set forth in Section 11.06.

     Section 11.10. 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 11 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 11.11. Trustee’s Adjustment Disclaimer. The Trustee has no duty to determine when an
adjustment under this Article 11 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 11.08 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 11. Each Conversion Agent shall have the same protection under
this Section 11.11 as the Trustee.

     Section 11.12. Rights Issued in Respect of Common Stock Issued Upon Conversion. (a) Each
share of Common Stock issued upon conversion of Notes pursuant to this Article 11 shall be entitled
to receive the appropriate number of rights (“Rights”), if any, and the certificates representing
Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be
provided by the terms of any future rights plan (i.e., a poison pill) adopted by the Company, as
the same may be amended form time to time, is in effect, (in each

63

 

case, a “Shareholders Rights
Plan”). Upon conversion of the Notes a Holder will receive, in addition to any Common Stock
received in connection with such conversion, the Rights under the Shareholders Rights Plan, unless
prior to any conversion, the Rights have separated from Common Stock, in which case the Applicable
Conversion Rate will be adjusted at the time of separation as if the Company distributed to all
holders of Common Stock, shares of Company Capital Stock, assets, debt securities or certain rights
to purchase securities of the
Company as described in Section 11.06(c), subject to readjustment in the event of the
expiration, termination or redemption of such rights. Any distribution of Rights pursuant to the
Shareholders Rights Plan that would allow a Holder to receive upon conversion, in addition to
shares of Common Stock, the Rights described therein (unless such Rights have separated from Common
Stock) shall not constitute a distribution of Rights that would entitle the Holder to an adjustment
to the Conversion Rate.

     (b) Rights or warrants distributed by the Company to all holders of Common Stock entitling
them to subscribe for or purchase shares of the Company’s capital stock (either initially or under
certain circumstances), which rights or warrants, until the occurrence of a specified event or
events (a “Trigger Event”): (1) are deemed to be transferred with such shares of Common Stock; (2)
are not exercisable; and (3) are also issued in respect of future issuances of Common Stock, shall
be deemed not to have been distributed for purposes of Section 11.06(b) or Section 11.06(c) as
applicable, (and no adjustment to the Conversion Rate under Section 11.06(b) or Section 11.06(c)
will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and
warrants shall be deemed to have been distributed and an appropriate adjustment to the Conversion
Rate shall be made under Section 11.06(b) or Section 11.06(c). If any such right or warrant,
including any such existing rights or warrants distributed prior to the date of this Indenture, are
subject to events, upon the occurrence of which such rights 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 record
date with respect to new rights or warrants with such rights (and a termination or expiration of
the existing rights or warrants without exercise by any of the holders thereof). In addition, in
the event of any distribution (or deemed distribution) of rights 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 11.06(b) or Section 11.06(c) was made, (1) in the case of any such rights or
warrants which shall all have been redeemed or purchased without exercise by any Holders thereof,
the Conversion Rate shall be readjusted upon such final purchase 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 purchase price received by a

64

 

holder of Common Stock with respect to
such rights or warrants (assuming such holder had retained such rights or warrants), made to all
applicable holders of Common Stock as of the date of such redemption or purchase, and (2) in the
case of such rights or warrants which shall have expired or been terminated without exercise by any
holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not
been issued.

ARTICLE 12

Payment of Interest

     Section 12.01. 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 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 12.02. Defaulted Interest. 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

65

 

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 20 days
and not less than 15 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 25 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 12.03. Interest Rights Preserved. Subject to the foregoing provisions of this
Article 12 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 13

Miscellaneous

     Section 13.01. Trust Indenture Act of 1939. This Indenture shall incorporate and be governed
by the provisions of the Trust Indenture Act that are required to be part of and to govern
indentures qualified under the Trust Indenture Act.

     Section 13.02. Noteholder Communications; Noteholder Actions. (a) The rights of Holders to
communicate with other Holders with respect to this Indenture or the Notes are as provided by the
Trust Indenture Act, and the

66

 

Company and the Trustee shall comply with the requirements of Trust
Indenture Act Sections 312(a) and 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 Holder
(an “act”) may be evidenced by an instrument signed by the Holder delivered to the 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.

     (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.

     Section 13.03. Notices. (a) Any notice or communication to the Company will be deemed given
if in writing (i) when delivered in person or (ii) five days after mailing when mailed by first
class mail, or (iii) when sent by facsimile transmission, with transmission confirmed. Any notice
to the Trustee will be effective only upon receipt. In each case the notice or communication
should be addressed as follows:
