ARTICLE 2
The Securities

Section 2.01. Title and Terms; Payments.There is hereby established a series of Securities designated the “3.50% Convertible Senior Notes due 2017” initially limited in aggregate principal amount to $143.75 million, which amount shall be as set forth in a Company Order for the authentication and delivery of Notes pursuant to Section 303 of the Original Indenture. The Notes shall be issuable in registered form (and shall constitute “Registered Securities” within the meaning of the Original Indenture) without coupons in denominations of $1,000 principal amount and integral multiples thereof.

The principal amount of Notes then outstanding shall be payable on the Maturity Date. Interest on the Notes shall accrue at a rate of 3.50% per annum, from December 15, 2010 or from the most recent date on which interest has been paid or duly provided for, until the principal thereof is paid or made available for payment. Interest on each Note shall be payable on each Interest Payment Date, beginning on June 15, 2011, in arrears, to the Person in whose name such Note is registered on the Security Register at the close of business on the Regular Record Date immediately preceding the applicable Interest Payment Date. If any Interest Payment Date, the Maturity Date or any Fundamental Change Repurchase Date falls on a day that is not a Business Day, the required payment shall be made on the next succeeding Business Day and no interest on such payment shall accrue in respect of such delay. Section 112 of the Original Indenture shall not apply to the Notes and shall be superseded in its entirety by this Section 2.01. Payments of the Fundamental Change Repurchase Price, principal and interest) that are payable but are not punctually paid or duly provided for shall accrue interest per annum at the rate borne by the Notes, subject to the enforceability thereof under applicable law.

The Company may, without the consent of the Holders, upon delivery of an Officer’s Certificate and Opinion of Counsel to the Trustee, hereafter issue additional Notes (“Additional Notes”) under the Indenture with the same terms as the Notes issued on the date of this Supplemental Indenture (the “Initial Notes”) in an unlimited aggregate principal amount;providedthat if such Additional Notes are issued with the same CUSIP number as the Initial Notes, such Additional Notes must be fungible with the Initial Notes for U.S. federal income tax purposes. Any such Additional Notes shall constitute a single series

together with the Initial Notes for all purposes hereunder, including, without limitation, for purposes of any waivers, supplements or amendments to the Indenture requiring the approval of Holders of the Notes and any offers to repurchase the Notes.

The Form of Note shall be substantially as set forth in Exhibit A and the Form of Notice of Conversion, the Form of Fundamental Change Repurchase Notice and the Form of Assignment and Transfer shall be substantially as set forth in Attachments 1, 2 and 3, respectively, to Exhibit A, each of which is incorporated into and shall be deemed a part of this Supplemental Indenture, and in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined to be necessary or appropriate by the Officers of the Company executing such Notes, as evidenced by their execution of the Notes.

The Company shall pay the principal of, and interest on, any Global Note registered in the name of or held by the Depositary or its nominee in immediately available funds to the Depositary or its nominee, as the case may be, as the registered Holder of such Global Note. The Company shall pay the principal of any Physical Notes at the office or agency designated by the Company for that purpose in accordance with Section 2.03.

The Company shall pay interest on any Physical Notes (A) to a Holder having an aggregate principal amount of $5,000,000 or less, by check mailed to such Holder at its address as it appears in the Security Register and (B) to a Holder having an aggregate principal amount of more than $5,000,000, either by check mailed to such Holder or, upon application by such a Holder to the Security Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to such Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Security Registrar to the contrary. Section 307 of the Original Indenture shall not apply to the Notes and shall be superseded in its entirety by this Section 2.01 and Section 4.02(h).

Section 2.02.Exchange and Registration of Transfer of Notes; Depositary.Sections 203 and 305 of the Original Indenture shall not apply with respect to the Notes, and shall be superseded in their entirety by this Section 2.02.

(a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 2.03, the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company

shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby appointed the “Security Registrar” for the purpose of registering Notes and transfers of Notes as herein provided.

Upon surrender for registration of transfer of any Note to the Security Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.02, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by the Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 2.03. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

All Notes presented or surrendered for registration of transfer or for exchange, required repurchase or conversion shall (if so required by the Company, the Trustee or the Security Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be imposed by the Company, the Trustee or the Security Registrar for any registration of transfer or exchange of Notes, but the Company, the Trustee or the Security Registrar may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax payable in connection therewith as long as, in the case of an exchange, such tax is payable as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

None of the Company, the Trustee or the Security Registrar shall be required to exchange or register a transfer of (i) any Note surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Note, or a portion of any Note, surrendered for required repurchase upon the occurrence of a Fundamental Change (and not withdrawn) in accordance with Article 3.

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

(b) Subject to the third paragraph of Section 2.02(c), all Notes shall be represented by one or more Global Notes registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note, shall be effected through the Depositary (not the Trustee or the Custodian) in accordance with the Indenture and the procedures of the Depositary therefor.

(c) Notwithstanding any other provisions of the Indenture (other than the provisions set forth in this Section 2.02(c)), a Global Note may not be transferred as a whole or in part except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to each Global Note. The Notes initially shall be issued in the form of one or more Global Notes without interest coupons (i) registered in the name of Cede & Co., as nominee of the Depositary and (ii) delivered to the Trustee as custodian for the Depositary.

The Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of the relevant Note or Notes, will authenticate and deliver (i) if (a) the Depositary notifies the Company that the Depositary is unwilling or unable to continue as Depositary for the Global Notes and a successor Depositary is not appointed within 90 days or (b) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor Depositary is not appointed within 90 days, Physical Notes to each Person the Depositary identifies as a beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Notes, in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be cancelled; or (ii) if an Event of Default with respect to the Notes has occurred and is continuing and any beneficial owner requests that its Global Note (or portion of a Global Note) be issued as a Physical Note, a Physical Note to such beneficial owner in a principal amount corresponding to such beneficial owner’s beneficial interest.

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.02(c) shall be registered in such names and in such

authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

At such time as all interests in a Global Note have been converted, cancelled, repurchased or transferred, such Global Note shall be, upon receipt thereof, cancelled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, cancelled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

Neither the Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

A legend in substantially the following form shall appear on the face of all Global Notes:

THIS NOTE IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE OF A DEPOSITARY. THIS NOTE IS EXCHANGEABLE FOR NOTES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND NO TRANSFER OF THIS NOTE (OTHER THAN A TRANSFER OF THIS NOTE AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY) MAY BE REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES.

SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

Section 2.03.Maintenance of Office or Agency.Section 1002 of the Original Indenture shall not apply with respect to the Notes, and shall be superseded in its entirety by this Section 2.03. The Company shall maintain an office or agency where the Notes may be surrendered for presentation for payment or repurchase (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office.

The Company hereby initially designates the Trustee as the Paying Agent, Custodian and Conversion Agent and the Corporate Trust Office and the agency of the Trustee in Minneapolis, Minnesota shall be considered as an office or agency of the Company for each of the aforesaid purposes.

The Place of Payment of the Notes for purposes of the Original Indenture shall be the location of the Paying Agent, as designated by the Company from time to time in accordance with this Section 2.03.

Section 2.04. Reporting Requirement.Section 703(1) of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 2.04. The reference to paragraph (1) of Section 703 of the Original Indenture in paragraph (3) of Section 703 of the Original Indenture shall be deemed to be a reference to this Section 2.04. The Company shall file with the Trustee within 15 days after the Company is required to file the same with the SEC (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act), copies of any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. Any such document or report that the Company files with the SEC via the EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 2.04 as of the time such document is filed via the EDGAR system.

Section 2.05. Purchase and Cancellation.Section 310 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by

this Section 2.05. The Company shall cause all Notes surrendered for payment, required repurchase upon the occurrence of a Fundamental Change, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be delivered to the Trustee for cancellation. All Notes delivered to the Trustee shall be cancelled promptly by the Trustee. No Notes shall be authenticated in exchange for any Notes cancelled, as provided herein. The Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, without giving prior notice to Holders, whether by the Company or the Company’s Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements.

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes.Section 306 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 2.06. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an Authenticating Agent shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such Authenticating Agent such security or indemnity as may be reasonably required by them to save each of them harmless from any loss, liability, cost or expense (including, without limitation, the reasonable fees and expenses of counsel) caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such Authenticating Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such Authenticating Agent may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such Authenticating Agent may reasonably require. Upon the issuance of any substitute Note, the Company or the Trustee may require the payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note that has matured or has been surrendered for required repurchase or has been surrendered for conversion in accordance with Article 4 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such

Authenticating Agent such security or indemnity as may be reasonably required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) the Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender.

Section 2.07.Who Are Deemed Absolute Owners.Section 309 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 2.07. The Company, the Trustee, any Authenticating Agent, any Paying Agent, any Conversion Agent and the Security Registrar may deem the Person in whose name a Note shall be registered upon the Security Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or the Security Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.01) accrued and unpaid interest on such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Conversion Agent nor the Security Registrar shall be affected by any notice to the contrary. All such payments or deliveries so made to any Holder, or upon its order, shall be valid, and, to the extent of the sum or sums so paid or shares of Common Stock so delivered, effectual to satisfy and discharge the liability for monies payable upon any such Note or shares deliverable in respect of any conversion thereof, as applicable. Notwithstanding anything to the contrary in the Indenture or the Notes following an Event of Default, any Holder of a beneficial interest in a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Note in certificated form in accordance with the provisions of the Indenture.

Section 2.08.Company Owned Notes.Notwithstanding clause (f) of the definition of “Outstanding” in Section 1.02, (x) for the purpose of determining whether the Trustee shall be protected in relying on any direction, consent, waiver or other action by Holders, only Notes that a Responsible Officer knows are owned by the Company or any Affiliate thereof shall be disregarded and deemed not to be Outstanding pursuant to such clause (f) and (y) Notes owned by the Company or any Affiliate thereof that have been pledged in good faith may be regarded as Outstanding under the Indenture and the Notes if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to take the relevant action with respect to such Notes and that the pledgee is not the Company or an Affiliate thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of the Company or any Affiliate thereof; and, subject to Section 602 of the Original Indenture, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are Outstanding for the purpose of any such determination.

Section 2.09.Revocation of Consents. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 104 of the Original Indenture, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Notes specified in the Indenture in connection with such action, any Holder of a Note that is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 104(a) of the Original Indenture, revoke such action so far as concerns such Note.

Section 2.10.Temporary Notes.Section 304 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 2.10. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an Authenticating Agent shall, upon written request of the Company as set forth in a Company Order, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company and notified to the Trustee in writing. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such Authenticating Agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company will execute and deliver to the Trustee or such Authenticating Agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any

Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 2.03 and the Trustee or such Authenticating Agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under the Indenture as Physical Notes authenticated and delivered hereunder.

ARTICLE 3
Fundamental Changes and Repurchases Thereupon

Section 3.01. Repurchase at Option of Holders Upon a Fundamental Change.(a) If a Fundamental Change occurs at any time, then each Holder of a Note shall have the right, at such Holder’s option, to require the Company to repurchase for cash such Holder’s Note, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple of $1,000, on a date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 nor more than 35 calendar days following the date the Company delivers the related Fundamental Change Company Notice pursuant to Section 3.01(b), at a repurchase price equal to 100% of the principal amount of the Note to be repurchased pursuant to this Article 3,plusaccrued and unpaid interest thereon, if any, to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of such accrued and unpaid interest, if any, on the Interest Payment Date to the Holder of record of such Note on such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of the Note to be repurchased pursuant to this Article 3.

To exercise the right to require the Company to repurchase its Note or a portion thereof upon a Fundamental Change in accordance pursuant to this Section 3.01, a Holder must:

(i) deliver to the Paying Agent a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, and comply with the Depositary’s procedures for surrendering interests in Global Notes if such Note is represented by an interest in a Global Note, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii) deliver such Note, in the case of a Physical Note, to the Paying Agent together with, or at any time after, delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent, or effect book-entry transfer of such Note (or such portion of a Note), if such Note is represented by an interest in a Global Note, in compliance with the procedures of the Depositary, in each case such delivery or transfer being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

Each Fundamental Change Repurchase Notice in respect of any Note (or portion of a Note) to be repurchased shall state:

(A) if such Note is a Physical Note, the certificate number of such Note;

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

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

provided,however, that if such Note is represented by an interest in a Global Note, the Fundamental Change Repurchase Notice must also comply with the applicable procedures of the Depositary.

(b) On or before the 20th calendar day after (i) the date the Company knew or reasonably should have known that the Fundamental Change occurred, in the case of a Fundamental Change described under clause (a) of the definition thereof, or (ii) the date the Fundamental Change occurred, in the case of any other Fundamental Change, the Company shall provide to all Holders of the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent other than the Trustee) a notice (the “Fundamental Change Company Notice”) of the occurrence of such Fundamental Change and of the repurchase right of the Holders arising as a result thereof. For the purpose of clause (i) of the preceding sentence, the Company shall be deemed to know of any Schedule TO or any other schedule, form or report filed under the Exchange Act by any person or group. Such notice shall be sent by first class mail or, in the case of any Global Notes, in accordance with the procedures of the Depositary for providing notices. Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a notice containing the information included therein 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 the Fundamental Change;

(ii) the effective date of the Fundamental Change;

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 3;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(ix) the procedures that a Holder must follow to require the Company to repurchase its Note.

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

(c) Notwithstanding the foregoing, there shall be no repurchase of any Note pursuant to this Section 3.01 on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from an Event of Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to any Note). The Paying Agent shall promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from an Event of Default by the Company in the payment of the Fundamental Change Repurchase Price

with respect to any Note), and any instructions for book-entry transfer of Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect to such Notes shall be deemed to have been withdrawn.

Section 3.02. Effect of Fundamental Change Repurchase Notice.Upon receipt by the Paying Agent of a Fundamental Change Repurchase Notice specified in Section 3.01, the Holder of the Note in respect of which such Fundamental Change Repurchase Notice was given shall (unless such Fundamental Change Repurchase Notice is withdrawn in accordance with Section 3.03) thereafter be entitled to receive the Fundamental Change Repurchase Price in cash with respect to such Note. Such Fundamental Change Repurchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the conditions in Section 3.01 have been satisfied) and (y) the time of delivery or book-entry transfer of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.01.

Section 3.03. Withdrawal of Fundamental Change Repurchase Notice.A Fundamental Change Repurchase Notice with respect to any Note may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Paying Agent in accordance with this Section 3.03 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, specifying:

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

(b) if such Note is a Physical Note, the certificate number of such withdrawn Note; and

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

provided,however, that if such Note is a Global Note, the notice must comply with the applicable procedures of the Depositary.

The Paying Agent will promptly return to the respective Holders thereof any Physical Notes with respect to which a Fundamental Change Repurchase Notice has been withdrawn in compliance with the provisions of this Section 3.03.

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

Section 3.04. Deposit of Fundamental Change Repurchase Price.Prior to 11:00 a.m. (local time in The City of New York) on the Fundamental Change Repurchase Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, the Company or such Subsidiary or Affiliate 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 Repurchase Price for each Note or portion of a Note that is to be repurchased as of the Fundamental Change Repurchase Date. If the Paying Agent on the Fundamental Change Repurchase Date holds cash sufficient to pay the Fundamental Change Repurchase Price of all Notes for which a Fundamental Change Repurchase Notice has been delivered and not withdrawn in accordance with this Article 3 as of the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, then as of such Fundamental Change Repurchase Date, (a) such Notes shall cease to be outstanding and interest on such Notes shall cease to accrue (whether or not book-entry transfer of such Notes is made or whether or not such Notes are delivered to the Paying Agent, as applicable) and (b) all other rights of the Holders with respect to such Notes shall terminate (other than the right to receive the Fundamental Change Repurchase Price of such Notes upon delivery or book-entry transfer of such Notes).

Section 3.05. Notes Repurchased in Whole or in Part.Upon surrender of any Note to be repurchased in part pursuant to this Article 3 to the Paying Agent in accordance with Section 3.01(a), 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 that is not repurchased.

Section 3.06. Covenant to Comply With Applicable Laws Upon Purchase of Notes.In connection with any offer to repurchase Notes under Section 3.01, the Company shall, in each case if required under such law or regulation, (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable, (ii) file a Schedule TO or any other required schedule under the Exchange Act and (iii) otherwise comply with all federal and state securities laws, in each case, 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.To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.04 exceeds the aggregate Fundamental Change Repurchase Price of the Notes or portions thereof that the Company is obligated to repurchase as of the Fundamental Change Repurchase Date, then, following the Fundamental Change

Repurchase Date, upon receipt of a Company Order, the Paying Agent shall promptly return any such excess to the Company.

ARTICLE 4
Conversion

Section 4.01. Conversion Privilege.(a) Holders may not convert their Notes prior to February 1, 2011, regardless of whether any of the following conditions are satisfied. Subject to and upon compliance with the provisions of this Article 4, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note (i) upon satisfaction of one or more of the conditions described in Section 4.01(b), on or after February 1, 2011, and prior to June 15, 2017 under the circumstances and during the periods set forth in Section 4.01(b), and (ii) regardless of whether any of the conditions set forth in Section 4.01(b) has been met, at any time on or after June 15, 2017 and prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at the Conversion Rate (subject to the settlement provisions of Section 4.02, the “Conversion Obligation”).

(b) (i) On or after February 1, 2011 and prior to June 15, 2017, the Notes may be surrendered for conversion in accordance with the Indenture during the five Business Day period immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this (i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day (the “Trading Price Condition”). The Company shall provide written notice to the Bid Solicitation Agent of the independent nationally recognized securities dealer or dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination by Company Order; and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate, at which time the Company shall instruct the Bid Solicitation Agent by Company Order to determine the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate. If the Trading Price Condition has been met pursuant to such

determination, the Bid Solicitation Agent shall so notify the Company and the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee), in each case within one Business Day of the Trading Price Condition being met. If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) within one Business Day. The Company hereby initially designates the Trustee to act as the Bid Solicitation Agent.

(ii) If, prior to June 15, 2017, the Company elects to:

(A) issue to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement of such issuance, to subscribe for or purchase shares of its Common Stock, at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of such announcement; or

(B) distribute to all or substantially all holders of its Common Stock the Company’s assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value, as reasonably determined by the Board of Directors, exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day preceding the date of announcement for such distribution,

then, in either case, the Company shall notify the Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) at least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution. If the Ex-Dividend Date for such issuance or distribution is on or after February 1, 2011, the Notes may be surrendered for conversion at any time during the period beginning on, and including, the later of (1) February 1, 2011 and (2) the Company’s delivery of such notice and ending at the earlier of close of business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and the Company’s announcement that such issuance or distribution will not take place, even if the Notes are not otherwise convertible at such time. Notes may not be surrendered for conversion pursuant to this Section 4.01(b)(ii) if Holders of such Notes have the right to participate (as a result of holding the Notes, and at the same time and on the same terms as common stockholders participate) in any of the transactions described in this Section

4.01(b)(ii) as if such Holders held a number of shares of the Common Stock, for each $1,000 principal amount of such Notes, equal to the applicable Conversion Rate, without having to convert such Notes.

(iii) If a transaction or event that constitutes (1) a Fundamental Change, (2) a Make-Whole Fundamental Change or (3) a consolidation, merger, combination or statutory share exchange involving the Company, or a sale, lease or other transfer of all or substantially all of its assets, pursuant to which the Common Stock would be converted into cash, securities or other assets, in each case (A) occurs after the 35th Trading Day prior to February 1, 2011 (or, if such transaction also constitutes a Fundamental Change, the related Fundamental Change Repurchase Date occurs after February 1, 2011), and (B) occurs prior to June 15, 2017, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 3.01, the Notes may be surrendered for conversion at any time from or after the date that is the later of (x) February 1, 2011 and (y) 35 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Company gives notice of such transaction) until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) (i) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 35 Scheduled Trading Days prior to the anticipated effective date of such transaction or (ii) if the Company does not have knowledge of such transaction at least 35 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction but in no event later than the actual effective date of such transaction.

(iv) On or after February 1, 2011 and prior to June 15, 2017, the Notes may be surrendered for conversion during any calendar quarter commencing after the calendar quarter ending on March 31, 2011 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 130% of the Conversion Price on each applicable Trading Day (the “Sales Price Condition”). The Company shall determine at the beginning of each calendar quarter commencing after the calendar quarter ending on March 31, 2011 whether the Sales Price Condition has been met and, if the Company determines that the Sales Price Condition has been met, the Company shall notify the Holders, the Trustee and the

Conversion Agent (if other than the Trustee) as soon as reasonably practicable after such determination.

Section 4.02. Conversion Procedure; Settlement Upon Conversion.

(a) Subject to this Section 4.02, Section 4.03(b) and Section 4.06(a), upon conversion of any Note, the Company shall satisfy its Conversion Obligation by paying or delivering, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of this Section 4.02 (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with subsection (j) of this Section 4.02 (“Combination Settlement”), at its election, as set forth in this Section 4.02.

(i) All conversions occurring on or after September 15, 2017 shall be settled using the same Settlement Method.

(ii) Prior to September 15, 2017, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions that occur on different Trading Days.

(iii) If, in respect of any Conversion Date or period of potential Conversion Dates, the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date or such period, as the case may be, the Company, through the Trustee, shall deliver such Settlement Notice to converting Holders (or in the case of a period of potential Conversion Dates, to all Holders) no later than the close of business on the second Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions occurring on or after September 15, 2017, no later than September 15, 2017). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount shall be equal to $1,000. If the Company delivers a Settlement Notice in accordance with the second preceding sentence electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount in such Settlement Notice, the Specified Dollar Amount shall be deemed to be $1,000. Each Settlement Notice shall specify (x) the relevant Settlement

Method, (y) in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount and (z) in the case of Physical Settlement or Combination Settlement, if the Company reasonably expects that it will deliver cash in lieu of shares of Common Stock otherwise deliverable upon such conversion pursuant to Section 4.11, the maximum number of shares the Company is permitted under ASX listing rules to deliver in respect of conversions on such Conversion Date.

(iv) The amount of cash, if any, and number of shares of Common Stock, if any, payable or deliverable by the Company upon any conversion of a Note (the “Settlement Amount”) shall be computed as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder, in respect of each $1,000 principal amount of such Note being converted, a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date;

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of such Note being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 25 consecutive Trading Days during the relevant Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of such Note being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 25 consecutive Trading Days during the relevant Observation Period.

(v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of any fractional share, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement

Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b) Subject to Section 4.02(d) and Section 4.02(e), before any Holder of a Note, or beneficial owner of an interest in a Global Note, shall be entitled to convert a Note as set forth above, such Holder or beneficial owner shall (i) in the case of a Global Note, comply with the procedures of the Depositary for converting a beneficial interest in a global note and, if required, pay funds equal to the amount of interest payable on the next Interest Payment Date to which such Holder is not entitled pursuant to Section 4.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”), at the office of the Conversion Agent and state in writing therein the principal amount of such Note to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank, at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to the amount of interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 4.02(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 4 on the Conversion Date for such conversion. No Notice of Conversion may be delivered with respect to any Note by the Holder thereof if such Holder has delivered a Fundamental Change Repurchase Notice to the Paying Agent in respect of such Note and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 3.03.

If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

(c) Each conversion of a Note shall be deemed to have been effected at the close of business on the date (the “Conversion Date”) that the Holder thereof has complied with the requirements set forth in subsection (b) above. Subject to Section 4.03(b) and Section 4.06(a), upon conversion of a Note, the Company shall pay or deliver, as the case may be, the consideration due in respect of the relevant Conversion Obligation (i) on the third Business Day immediately following the relevant Conversion Date, if the Company elects to satisfy such Conversion Obligation by Physical Settlement, or (ii) on the third Business Day immediately following the last Trading Day of the relevant Observation Period, if

the Company elects to satisfy such Conversion Obligation by any other Settlement Method. If any shares of Common Stock are due to a converting Holder, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or make a book-entry transfer through the Depositary to such Holder or such Holder’s nominee or nominees for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(d) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issuance of any shares of Common Stock upon conversion, unless such tax is due because such Holder requests such shares to be issued in a name other than such Holder’s name, in which case such Holder shall pay such tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f) Except as provided in Section 4.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any Note as provided in this Article 4.

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

(h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. Upon conversion of a Note, the Company’s settlement of its Conversion Obligation with respect to such Note in accordance with this Section 4.02 shall be deemed to satisfy in full the Company’s obligation to pay the principal amount of such Note

and accrued and unpaid interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes to which Combination Settlement applies, accrued and unpaid interest shall be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding such conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted;providedthat no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

(i) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered, or to whom book entry transfer of such shares is made, pursuant to Section 4.02(c) shall be treated as if such person were the holder of record of such shares as of (i) the close of business on the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or (ii) the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be, in each case solely for the purpose of receiving or participating in any dividend, distribution, issuance, share split or combination, tender or exchange offer or any other event that would lead to a Conversion Rate Adjustment pursuant to Section 4.03 or Section 4.04. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion, except for purposes of Section 4.02(h) and receiving consideration due upon conversion.

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of any fractional share of Common Stock issuable upon conversion based on the Daily VWAP on the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate

Daily Settlement Amounts for the applicable Observation Period and any fractional shares remaining after such computation shall be paid in cash.

Section 4.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes.(a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. The conversion of a Note shall be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if the Notice of Conversion with respect to such Note is received by the Conversion Agent from, and including, the Effective Date of such 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 a Make-Whole Fundamental Change that would have been a Fundamental Change but for theprovisoin clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change).

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 4.02;provided,however, that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change (without giving effect to theprovisotherein), the Reference Property is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate in effect on the Conversion Date (including any adjustment for Additional Shares),multiplied bysuch Stock Price. In such event, such amount of cash shall be paid to the converting Holder on the third Business Day following the relevant Conversion Date. The Company shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of

Fundamental Change (without giving effect to theprovisotherein), the Stock Price shall be the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors as evidenced by a Board Resolution shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any 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, during such five consecutive Trading Day period.

(d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices in effect immediately prior to such adjustmentmultiplied bya fraction, the numerator of which is the Conversion Rate in effect immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 4.04.

(e) The following table sets forth the number of Additional Shares to be added to the Conversion Rate per $1,000 principal amount of Notes pursuant to this Section 4.03 for each Stock Price and Effective Date set forth below:

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

(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, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices or the earlier and later Effective Dates based on a 365-day year, as applicable;

(ii) if the Stock Price is greater than $450.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the

column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $81.31 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed 12.2986 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 4.04.

(f) Nothing in this Section 4.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 4.04 in respect of a Make-Whole Fundamental Change.

Section 4.04. Adjustment of Conversion Rate.The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustment to the Conversion Rate if each Holder has the right to participate, at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding its Note, in any of the transactions described in this Section 4.04, without having to convert its Note, as if it held a number of shares of Common Stock, per $1,000 principal amount of its Note, equal to the Conversion Rate.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on shares of its Common Stock, or if the Company effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:


		CR₁ = CR₀ x		OS₁
		CR₁ = CR₀ x		OS₀


where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or combination, as applicable;

CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date or effective date;


OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date; and

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

Any adjustment made under this Section 4.04(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 4.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors as evidenced by a Board Resolution determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all or substantially all holders of its Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of such announcement, the Conversion Rate shall be increased based on the following formula:


		CR₁ = CR₀ x		OS₀ + X
		CR₁ = CR₀ x		OS₀ + Y


where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such issuance;

CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on such Ex-Dividend Date;

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


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

Any increase made under this Section 4.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For the purpose of this Section 4.04(b) and for the purpose of Section 4.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 4.04(a) or Section 4.04(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 4.04(d), and (iii) Spin-Offs as to which the provisions set forth below in this Section 4.04(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:


		CR₁ = CR₀ x		SP₀ SP₀ — FMV


where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR₁	=	the Conversion Rate in effect immediately after the open of business on such Ex-Dividend Date;

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

FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property distributed with respect to each outstanding share of the Common Stock on the Ex-Dividend Date for such distribution.

Any increase made under the portion of this Section 4.04(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any Distributed Property for purposes of this Section 4.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 4.04(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:


		CR₁ = CR₀ x		FMV₀ + MP₀ MP₀


where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such Spin-Off;

CR₁	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such Spin-Off;

FMV₀	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.02 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period after, and including, the Ex-Dividend Date of the Spin-Off (the “Valuation Period”); and

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

The increase to the Conversion Rate under the preceding paragraph shall be determined on the last Trading Day of the Valuation Period but shall be given effect immediately after the open of business on the Ex-Dividend Date for the Spin-Off;providedthat in respect of any conversion during the Valuation Period, references in the portion of this Section 4.04(c) related to Spin-Offs to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the relevant Conversion Date. If the Ex-Dividend Date for the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references in the portion of this Section 4.04(c) related to Spin-Offs to 10 Trading Days shall be deemed replaced, for purposes of calculating the daily Conversion Rates for such conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, and including, the last Trading Day of such Observation Period.

For purposes of this Section 4.04(c) (and subject in all respects to Section 4.10), rights, options or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with

such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.04(c) (and no adjustment to the Conversion Rate under this Section 4.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 4.04(c). If any such right, option or warrant are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 4.04(c) was made, (1) in the case of any such rights, options or warrants that shall all have been repurchased without exercise by any Holders thereof, upon such final repurchase (x) the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of Section 4.04(a), Section 4.04(b) and this Section 4.04(c), if any dividend or distribution to which this Section 4.04(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 4.04(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 4.04(b) is applicable (the “Clause B Distribution”),

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 4.04(c) is applicable (the “Clause C Distribution”) and any

Conversion Rate adjustment required by this Section 4.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 4.04(a) and Section 4.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or effective date” within the meaning of Section 4.04(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 4.04(b).

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


		CR₁ = CR₀ x		SP₀
		CR₁ = CR₀ x		SP₀ — C


where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

CR₁	=	the Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

SP₀	=	the Last Reported Sale Price of the 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 its Common Stock.

Any increase pursuant to this Section 4.04(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a

Note shall receive, for each $1,000 principal amount of such Note, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned on the relevant record date a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for the Common Stock and the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the 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:


		CR₁ = CR₀ x		AC + (SP₁ x OS₁) OS₀ x SP₁


where,

CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;

CR₁	=	the Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;

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

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

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

SP₁	=	the average of the Last Reported Sale Prices of the 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.

The increase to the Conversion Rate under this Section 4.04(e) shall be determined at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires but shall be given effect immediately after the open of business on the Trading Day next succeeding the date such tender or exchange offer expires;providedthat in respect of any conversion within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references in this Section 4.04(e) with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Trading Day next succeeding the expiration date of such tender or exchange offer and the Conversion Date in determining the Conversion Rate. If the Trading Day immediately following the date the tender or exchange offer expires is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion references in this Section 4.04(e) to 10 Trading Days shall be deemed replaced, for purposes of calculating the affected daily Conversion Rates for such conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day immediately following the date such tender or exchange offer expires to, and including, the last Trading Day of such Observation Period.

(f) Notwithstanding this Section 4.04 or any other provision of the Indenture or the Notes, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date, and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date (or such Holder’s nominee or nominees) would be treated as if such person were the record holder of the shares of Common Stock as of the related Conversion Date for the purpose of participating in the event giving rise to such Conversion Rate adjustment pursuant to Section 4.02(i) based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate adjustment provisions in Section 4.03 and this Section 4.04, the Conversion Rate adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 4.04 and Section 4.03, and to the extent permitted by applicable law and subject to the applicable rules of The NASDAQ Global Market and any other exchange on which any of the Company’s securities are then listed (i) the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors

determines that such increase would be in the Company’s best interest and (ii) the Company may (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the Holder of each Note at its last address appearing on the Security Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(h) All adjustments to the Conversion Rate and other calculations under this Article 4 with respect to a number of shares shall be made to the nearest one ten-thousandth (1/10,000) of a share.

(i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s 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 Holder at its last address appearing on the Security Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(j) For purposes of this Section 4.04, 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.

Section 4.05. Adjustments of Prices.Whenever any provision of the Indenture requires the Company to calculate Last Reported Sale Prices, Daily VWAPs, Daily Conversion Values or Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period, if any, over which the Stock Price is determined for purposes of a Make-Whole Fundamental Change), the Board of Directors as evidenced by a Board Resolution shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the

Conversion Rate where the Ex-Dividend Date of such event occurs, at any time during the period when such Last Reported Sale Prices, Daily VWAPs, Daily Conversion Values or Daily Settlement Amounts are to be calculated.

Section 4.06 . Effect of Recapitalizations, Reclassifications and Changes of the Common Stock.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination),

(ii) any consolidation, merger or combination involving the Company,

(iii) any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety, or

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities or other property or assets (including cash or any combination thereof) (any such event, a “Merger Event”), then, at and after the effective time of such Merger Event, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property,” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture under Section 7.01(f) providing for such change in the right to convert each $1,000 principal amount of Notes, which change is hereby deemed, for purposes of Section 7.01(f), to not adversely affect the rights of any Holder;provided,however, that at and after the effective time of such Merger Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 4.02 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 4.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with

Section 4.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Merger Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible (subject to the preceding sentence) shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders receive only cash in such Merger Event, then for all conversions that occur after the effective date of such Merger Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the relevant Conversion Date (as may be increased by any Additional Shares pursuant to Section 4.03),multiplied bythe price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy its Conversion Obligation with respect to each such conversion by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 4. If, in the case of any Merger Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Merger Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing.

(b) In the event the Company shall execute a supplemental indenture pursuant to subsection (a) of this Section 4.06, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefore, the kind or amount of cash, securities or property or assets that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all relevant conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each

Holder, at its address appearing on the Security Register provided for in the Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 4.01 and Section 4.02 prior to the effective date of such Merger Event.

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

Section 4.07. Certain Covenants. (a) The Company shall reserve, out of its authorized but unissued shares or shares held in treasury, the maximum number of shares of Common Stock potentially required to satisfy conversion of the Notes from time to time as Notes are presented for conversion.

(b) The Company covenants that all shares of Common Stock that may be issued upon conversion of a Note will be newly issued shares or treasury shares, and will be duly authorized, fully paid and non-assessable and free from all taxes, liens and charges (other than those created by the Holder thereof).

(c) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be.

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

Section 4.08. Responsibility of Conversion Agent and Trustee.The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Bid Solicitation Agent shall be entitled to assume that the Conversion Rate in effect on any date is equal to the Conversion Rate set forth in the most recent Officer’s Certificate filed with the Trustee pursuant to Section 4.04(i) or, if no such Officer’s Certificate has been filed, the

Conversion Rate in effect on the date hereof. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent and the Bid Solicitation Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent nor the Bid Solicitation Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 4. The rights, privileges, protections, immunities and benefits given to the Trustee, including without limitation its right to be compensated, reimbursed, and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including its capacities as Conversion Agent and Bid Solicitation Agent.

Section 4.09.Notice to Holders Prior to Certain Actions.In case of any:

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 4.04 or Section 4.10;

(b) Merger Event; or

then, in each case (unless notice of such event is otherwise required pursuant to another provision of the Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed (at the Company’s expense) to each Holder at its address appearing on the Security Register provided for in the Indenture, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.

Section 4.10.Stockholder Rights Plans.To the extent that the Company has a rights plan in effect upon a conversion of the Notes to which Combination Settlement or Physical Settlement applies, each share of Common Stock issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time;providedthat if at the time of conversion, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan so that the Holders would not be entitled to receive any rights in respect of Common Stock issuable upon conversion of the Notes, the Conversion Rate shall be increased pursuant to Section 4.04(c) at the time of separation as if the Company distributed to all or substantially all holders of Common Stock shares of Capital Stock of the Company, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 4.11.Limit on Issuance of Shares of Common Stock Upon Conversion.Notwithstanding anything to the contrary herein, if CHESS Depositary Interests representing the Common Stock are then listed on the Australian Securities Exchange (the “ASX”), in the event of an increase in the Conversion Rate pursuant to this Article 4 beyond the Share Cap or if the Company would otherwise be required to deliver a number of shares of Common Stock per $1,000 principal amount of Notes in respect of any Conversion Date in excess of the Share Cap, the Company shall, at its option, either (I) obtain shareholder ratification for the issuance of the Notes and the Common Stock underlying the Notes, in accordance with ASX listing rules, prior to such conversion, or (II) upon conversion of the Notes, deliver an amount of cash in lieu of any shares of Common Stock otherwise deliverable in excess of the Share Cap based on (x) the Daily VWAP on each Trading Day of the relevant Observation Period, in the case of Combination Settlement, or (y) the Daily VWAP on the Conversion Date, in the case of Physical Settlement. If the Company shall not have obtained shareholder ratification as set forth above and reasonably expects that the number of shares of Common Stock it would be required to deliver in respect of any conversion without regard to this Section 4.11 would exceed the Share Cap, the Company shall, to the extent practicable either (1) elect Cash Settlement pursuant to Section 4.02 with respect to such conversion or (2) elect Combination Settlement pursuant to Section 4.02, and specify a Specified Dollar Amount with respect to such conversion that the Company reasonably expects will not cause the number of shares of Common Stock to be delivered upon conversion to exceed the Share Cap. If the Company pays cash in lieu of shares of Common Stock pursuant to this Section 4.11 in respect of its Conversion Obligation, the amount of such cash shall be the same, per $1,000 principal amount of Notes, for all Notes surrendered for conversion on a single Conversion Date.

In particular, the reference to “clauses (1), (2) or (3) of Section 501” in Section 602(13) of the Original Indenture shall be deemed to be a reference to clauses (a), (b) and (d) of this Section 5.01.

excess of $25 million in the aggregate of the Company and/or any such Subsidiary (it being understood that the amount of any Indebtedness shall be determined after giving effect to any prior repayment thereof), whether such Indebtedness now exists or shall hereafter be created (i) resulting in such Indebtedness becoming or being declared due and payable, if such declaration of acceleration is not rescinded or annulled within 10 days after the Company has received notice of such acceleration or (ii) constituting a failure to pay the principal of or interest on any such Indebtedness when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, if such default is not cured or waived within 10 days after the date when the payment was due;providedthat, in the case of clause (i), if such declaration of acceleration is annulled or rescinded or, in the case of clause (ii), if such default is cured or waived, the related Event of Default with respect to the Notes shall be deemed to be cured for the purposes of the Indenture;

(i) the Company or any Significant Subsidiary shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any such Significant Subsidiary or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or fails generally to pay its debts as they become due;

Section 5.02.Acceleration; Rescission and Annulment.If an Event of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any

order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 5.01(i) or Section 5.01(j) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then Outstanding, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100% of the principal of, and any accrued and unpaid interest on, all of the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, notwithstanding any provision in the Indenture or in the Notes to the contrary. In the case of an Event of Default specified in Section 5.01(i) or Section 5.01(j) with respect to the Company, 100% of the principal of, and any accrued and unpaid interest on, all of the Notes shall automatically become immediately due and payable.

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of and interest on the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, (1) the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal, at the rate borne by the Notes at such time) and amounts due to the Trustee pursuant to Section 606 of the Original Indenture, and (2) rescission would not conflict with any order or decree of a court of competent jurisdiction and (3) any and all existing Events of Default under the Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 5.09, then and in every such case the Holders of a majority in aggregate principal amount of the Notes then Outstanding may, by written notice to the Company and to the Trustee, rescind and annul any consequence of any such Default or Event of Default with respect to any action taken on behalf of all of the Holders, including, without limitation, acceleration of the obligations, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture; but no such rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon.

Section 5.03.Additional Interest.Notwithstanding any provisions of the Indenture to the contrary, if the Company so elects, the sole remedy during the first 270 days following an Event of Default relating to (i) the Company’s failure to file with the Trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that it is required to file with the SEC pursuant to

Section 13 or 15(d) of the Exchange Act or (ii) its failure to comply with its reporting obligations set forth in Section 2.04, shall consist exclusively of the right to receive additional interest on the Notes, as long as such Event of Default is continuing, at a rate equal to (x) 0.25% per annum of the principal amount of the Notes outstanding (“Additional Interest”) for each day during the 90-day period beginning on, and including, the date on which such Event of Default first occurs and (y) 0.50% per annum of the principal amount of the Notes outstanding during the 180-day period beginning on, and including, the 91st day that such Event of Default is continuing. If the Company elects to pay Additional Interest on account of such an Event of Default, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 271st day after such Event of Default occurs (if such Event of Default relating to reporting obligations set forth in Section 2.04 is not cured or waived on or prior to such 271st day), the Notes shall be subject to acceleration as provided in Section 5.02. This Section 5.03 shall not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default.

In order to elect to pay Additional Interest as the sole remedy during the first 270 days after the occurrence of an Event of Default described in the immediately preceding paragraph, the Company must give notice to all Holders of Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 270-day period. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 5.03 or the Company elected to make such payments but does not pay the Additional Interest when due, the Notes shall be subject to acceleration as provided in Section 5.02.

Section 5.04.Payments of Notes on Default; Suit Therefor.If an Event of Default described in clause (a), (b) or (d) of Section 5.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal (including the Fundamental Change Repurchase Price, if applicable) and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 606 of the Original Indenture. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under title

11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 5.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 606 of the Original Indenture; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including reasonable agents and counsel fees, and including any other amounts due to the Trustee under Section 606 of the Original Indenture, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

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

All rights of action and of asserting claims under the Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of

the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of the Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings.

In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned because of any waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders, and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders, and the Trustee shall continue as though no such proceeding had been instituted.

Section 5.05.Application of Monies Collected by Trustee.Any monies or property collected by the Trustee pursuant to this Article 5 with respect to the Notes shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First, to the payment of all amounts due the Trustee under Section 606 of the Original Indenture;

Second, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto;

Third, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal

of and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest, to the extent permitted by applicable law, at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and

Fourth, to the payment of the remainder, if any, to the Company or as otherwise directed by a court of competent jurisdiction.

Section 5.06.Proceedings by Holders.Except to enforce the right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing itself of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a) such Holder previously shall have given to the Trustee notice of an Event of Default and of the continuance thereof, as herein provided;

(b) Holders of at least 25% in aggregate principal amount of the Notes then Outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;

(c) such Holder or Holders shall have offered, and, if requested, provided, to the Trustee such security or indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby; and

(d) the Trustee shall not have complied with such request for 60 days after its receipt of such notice, request and offer of security or indemnity and does not receive, during those 60 days, from Holders of a majority in aggregate principal amount of the Notes then Outstanding, a direction pursuant to Section 5.09 that is inconsistent with the request, it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to

enforce any right under the Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 5.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of the Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder.

Section 5.07.Proceedings by Trustee.In case of an Event of Default the Trustee may proceed to protect and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law.

Section 5.08.Remedies Cumulative and Continuing.All powers and remedies given by this Article 5 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 5.06, every power and remedy given by this Article 5 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.

Section 5.09.Direction of Proceedings and Waiver of Defaults by Majority of Holders. Subject to Section 602 of the Original Indenture, the Holders of a majority in aggregate principal amount of the Notes then Outstanding shall have the right to (i) direct the Trustee to exercise any remedy available to it with respect to the Notes and (ii) direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of

exercising any trust or power conferred on the Trustee with respect to Notes;provided,however, that the Trustee may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Holders of a majority of the aggregate principal amount of the Notes then Outstanding may on behalf of the Holders of all of the Notes, by written notice to the Trustee and the Company, waive any Default or Event of Default hereunder except that no such waiver shall be effective as to a Default or Event of Default with respect to (i) the non-payment of the principal (including the Fundamental Change Repurchase Price) of, or accrued and unpaid interest, if any, on the Notes, (ii) a failure by the Company to pay or deliver, as the case may be, to converting Holders the consideration due upon conversion of the Notes in accordance with the Indenture or (iii) any provision of the Indenture that under Article 7 cannot be modified or amended without the consent of the Holder of each Outstanding Note affected, in each case unless each affected Holder consents Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 5.09, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 5.10.Notice of Defaults.The Trustee shall, within 90 days after the occurrence of a Default or Event of Default of which a Responsible Officer has actual knowledge transmit to each Holder at the address of such Holder on the Security Register, notice of all Defaults or Events of Default known to any Responsible Officer, unless such Defaults or Events of Default shall have been cured or waived before the giving of such notice;providedthat, except in the case of a Default or Event of Default in the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any of the Notes or a Default or Event of Default in the payment or delivery, as the case may be, of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and for so long as the board of directors, the executive committee, a trust committee of directors or a committee of Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders. Section 601 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 5.10.

Section 5.11.Statements as to Defaults.Section 1004 of the Original Indenture shall not apply to the Notes, and shall be superseded in its entirety by this Section 5.11. The Company shall deliver to the Trustee in accordance with Section 105 of the Original Indenture, as soon as practicable, and in any event

within 30 days after an Officer of the Company first becomes aware of the occurrence of any Event of Default or Default, an Officer’s Certificate setting forth the details of such Event of Default or Default, its status and the action that the Company is taking or proposes to take in respect thereof, and such Officer’s Certificate shall reference the Indenture and the Notes. The Company shall also deliver to the Trustee, in accordance with Section 105 of the Original Indenture, within 120 days after the end of each fiscal year of the Company, an Officer’s Certificate indicating whether the signers thereof know of any Default or Event of Default that occurred in the previous year and, if so, specifying each such Default or Event of Default and the nature thereof, and such Officer’s Certificate shall reference the Indenture and the Notes. The provisions in the second paragraph of Section 102 of the Original Indenture shall not apply to any Officer’s Certificate delivered pursuant to this Section 5.11.

Section 5.12.Further Instruments and Acts.Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of the Indenture.

Section 5.13.Undertaking to Pay Costs.All parties to the Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under the Indenture or the Notes, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;providedthat the provisions of this Section 5.13 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price with respect to the Notes being purchased as provided in Article 3) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 4.

ARTICLE 6
Satisfaction and Discharge

Section 6.01.Satisfaction and Discharge of the Supplemental Indenture.Articles Four and Fourteen of the Original Indenture shall not apply to the Notes.

Instead, the satisfaction and discharge provisions set forth in this Article 6 shall, with respect to the Notes, supersede in their entirety Articles Four and Fourteen of the Original Indenture and all references in the Original Indenture to Article Four thereof and satisfaction and discharge provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 6 and the satisfaction and discharge provisions set forth in this Article 6. The Indenture, with respect to the Notes, shall upon request of the Company contained in an Officer’s Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Supplemental Indenture, when (a) (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.06) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether at the Maturity Date, on any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or, solely to satisfy outstanding conversions, cash and/or shares of Common Stock, as applicable, sufficient to pay all of the outstanding Notes or satisfy the Company’s Conversion Obligation, as the case may be, and pay all other sums due and payable under this Supplemental Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of the Indenture have been complied with. For the avoidance of doubt, notwithstanding the satisfaction and discharge of the Indenture, the obligations of the Company to the Trustee under Section 606 of the Original Indenture shall survive.

Section 6.02. Deposited Monies and Shares of Common Stock to be Held in Trust by Trustee. Subject to Section 1003 of the Original Indenture, all monies and shares of Common Stock, if any, deposited with the Trustee pursuant to Section 6.01 shall be held in trust for the sole benefit of the Holders of the Notes, and such monies and shares of Common Stock shall be applied by the Trustee to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders of the particular Notes for the payment or settlement of which such monies or shares of Common Stock have been deposited with the Trustee, of all sums or amounts due and to become due thereon for principal and interest, if any, or to satisfy the Company’s Conversion Obligation, as the case may be. Money so held in trust is subject to the Trustee’s rights under Section 606 of the Original Indenture.

Section 6.03.Paying Agent to Repay Monies Held.Upon the satisfaction and discharge of the Indenture, with respect to the Notes, all monies and shares of Common Stock, if any, then held by the Trustee or any Paying Agent (if other than the Trustee) shall, upon written request of the Company, be repaid or re-delivered to it or, in the case of a Paying Agent other than the Trustee, paid or

delivered to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies and shares of Common Stock.

Section 6.04.Reinstatement.If the Trustee or the Paying Agent is unable to apply any money or shares of Common Stock in accordance with Section 6.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 6.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money and shares of Common Stock in accordance with Section 6.02;provided, however, that if the Company makes any payment of interest on, principal of or payment or delivery in respect of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment or delivery from the money or shares of Common Stock, if any, held by the Trustee or Paying Agent.

Section 7.01.Supplemental Indentures Without Consent of Holders.Article Nine of the Original Indenture shall not apply to the Notes. Instead the provisions set forth in this Article 7 shall, with respect to the Notes, supersede in their entirety Article Nine of the Original Indenture, and all references in the Original Indenture to Article Nine thereof and provisions therein, as the case may be, shall, with respect to the Notes, be deemed to be references to this Article 7 and provisions set forth in this Article 7, respectively. The Company and the Trustee may amend or supplement the Indenture or the Notes without notice to or the consent of any Holder of the Notes to:

(a) cure any ambiguity, omission, defect or inconsistency that does not adversely affect Holders of the Notes;

(b) provide for the assumption by a Successor Company of the obligations of the Company under the Indenture and the Notes pursuant to Article 8;

Section 7.02. Supplemental Indentures with Consent of Holders.The provisions set forth in this Section 7.02 shall, with respect to the Notes, supersede in their entirety Section 1009 of the Original Indenture. If authorized by the Board of the Directors as set forth in a Board Resolution, the Company and the Trustee may amend or supplement this Supplemental Indenture or the Notes, and compliance with any provision of the Indenture or the Notes may be waived, in each case with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then Outstanding (including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes), at the expense of the Company;providedthat no amendment or supplemental indenture or waiver may without the written consent of the Holder of each Note affected:

(a) reduce the amount of Notes whose Holders must consent to an amendment;

(b) reduce the rate of or extend the stated time for payment of interest on any Note;

(d) make any change that adversely affects the conversion rights of any Notes;

(f) make any Note payable in money other than that stated in the Note;

(g) change the ranking of the Notes;

(h) impair the right of any Holder to receive payment of principal of and interest on such Holder’s Notes on or after the due dates therefor or to institute

suit for the enforcement of any payment on or with respect to such Holder’s Note; or

(i) make any change in this proviso or in the waiver provisions in Section 5.09.

Holders do not need under this Article 7 to approve the particular form of any proposed amendment to the Indenture or any proposed supplemental indenture; it shall be sufficient if the required number of Holders approve the substance thereof.

Section 7.03. Notice of Amendment or Supplement.After an amendment or supplement under this Article 7 becomes effective, the Company shall mail to the Holders a notice briefly describing such amendment or supplement. However, the failure to give such notice to all the Holders, or any defect in the notice, shall not impair or affect the validity of the amendment or supplement.

Section 7.04. Execution of Supplemental Indentures. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by the Indenture, the Trustee shall receive, and shall be fully protected in conclusively relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by the Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise.

Section 7.05.Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, the Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of the Indenture for all purposes; and every Holder theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

Section 7.06.Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act as then in effect.

Section 7.07.Reference in Notes to Supplemental Indentures. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form satisfactory to the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Company to the Indenture as amended or supplemented by such supplemental indenture may be prepared and executed by the Company, and authenticated and delivered by the Trustee in exchange for outstanding Notes.

ARTICLE 8
Successor Company

Section 8.01. Consolidation, Merger and Sale of Assets.Article Eight of the Original Indenture shall not apply to the Notes. The provisions set forth in this Article 8 shall, with respect to the Notes, supersede in their entirety Article Eight of the Original Indenture, and all references in the Original Indenture to Article Eight thereof shall, with respect to the Notes, be deemed to be references to this Article 8. The Company shall not consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to, another Person, unless:

(a) the resulting, surviving or transferee Person (if not the Company) (the “Successor Company”) is organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and such Successor Company (if not the Company) expressly assumes by supplemental indenture all of the Company’s obligations under the Notes and the Indenture;

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under the Indenture; and

(c) the Company shall have delivered to the Trustee the Officer’s Certificate and Opinion of Counsel pursuant to Section 8.03.

For purposes of this Section 8.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company to another Person that is not a Subsidiary of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of the Company to another Person.

Section 8.02. Successor Person Substituted.Upon any such consolidation, merger, sale, transfer, lease or other conveyance in which the Company is not the Successor Company and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee, of the due and punctual payment of the principal of and interest on all of the Notes, and the due and punctual performance and observance of all of the covenants and conditions of the Indenture to be performed or satisfied by the Company, such Successor Company shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and the Notes, with the same effect as if it had been named herein as the party of the first part, and the Company shall be discharged from its obligations under the Notes and the Indenture, except in the case of a lease of all or substantially all of the Company’s

properties and assets. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder that theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, transfer or conveyance (but not in the case of a lease) upon compliance with this Article 8 the Person named as the “Company” in the first paragraph of the Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 8 may be dissolved, wound up and liquidated at any time thereafter and such Person shall be discharged from its liabilities as obligor and maker of the Notes and from its obligations under the Indenture.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Section 8.03. Opinion of Counsel to be Given to Trustee.Prior to execution of any supplemental indenture pursuant to this Article 8, the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel that meets the requirements of Section 102 of the Original Indenture as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption complies with the provisions of this Article 8.

ARTICLE 9
Lists Of Holders

Section 9.01.Lists of Holders.The Company covenants and agrees that it will furnish or cause to be furnished to the Trustee, semi-annually, not more than 15 days after each June 1 and December 1 in each year beginning with June 1, 2011, and at such other times as the Trustee may request in writing, within 30 days after receipt by the Company of any such request (or such lesser time as the Trustee may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list in such form as the Trustee may reasonably require of the names and addresses of the Holders as of a date not more than 15

days (or such other date as the Trustee may reasonably request in order to so provide any such notices) prior to the time such information is furnished, except that no such list need be furnished so long as the Trustee is acting as Security Registrar. In addition, the Trustee and the Company shall comply with Section 312 of the Trust Indenture Act.

Section 9.02.Preservation and Disclosure of Lists.The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders contained in the most recent list furnished to it as provided in Section 9.01 or maintained by the Trustee in its capacity as Security Registrar, if so acting. The Trustee may destroy any list furnished to it as provided in Section 9.01 upon receipt of a new list so furnished.

ARTICLE 10
No Redemption

Section 10.01.No Redemption. The Notes shall not be redeemable by the Company prior to the Maturity Date, and no sinking fund is provided for the Notes. The provisions in Articles Eleven and Twelve of the Original Indenture shall not apply to the Notes.

ARTICLE 11
Covenant to Comply with Australian Securities Exchange Listing Rules

Section 11.01. Australian Securities Exchange.As long as CHESS Depositary Interests representing the Common Stock are listed on the ASX, prior to February 1, 2012, the Company shall not issue any shares of Common Stock (other than upon a conversion of Notes) or any securities convertible into Common Stock unless either (x) the Company’s shareholders approve such proposed issuance; (y) the Company’s shareholders ratify the issuance of the Notes and the Common Stock underlying the Notes; or (z) ASX provides a waiver of the requirement to seek shareholder approval for the issue of shares of common stock or securities convertible into common stock, in each case within the meaning of applicable ASX rules and regulations.

Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.

This Note is not subject to redemption prior to maturity. No sinking fund is provided for the Note.

The provisions in Articles Four, Five, Eight, Nine, Eleven, Twelve, Thirteen and Fourteen, and Sections 112, 203, 304, 305, 306, 307, 309, 310, 312, 313, 601, 703(1), 1002, 1004, 1008 and 1009, and the definitions of “Officer’s Certificate” and “Outstanding” in Section 101 of the Original Indenture shall not apply to the Notes, and Article 5, Article 6, Article 7, Article 8, Section 2.01, Section 2.02, Section 2.03, Section 2.04, Section 2.05, Section 2.06, Section 2.07, Section 2.10, Section 4.02(h), Section 5.10, Section 5.11, and the definition of “Officer’s Certificate” and “Outstanding” in Section 1.02 of the Supplemental Indenture supersede the entirety thereof.

As provided in and subject to the provisions of the Indenture, upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

As provided in and subject to the provisions of the Indenture, the Holder hereof may not convert this Note prior to February 1, 2011 under any circumstances. On or after February 1, 2011, the Holder hereof has the right, at its option (i) during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to June 15, 2017, and (ii) on or after June 15,

As provided in and subject to the provisions of the Supplemental Indenture, the Company shall make all payments in respect of the Fundamental Change Repurchase Price and the principal amount on the Fundamental Change Repurchase Date or the Maturity Date thereof, as the case may be, to the Holder who surrenders a Note to the Paying Agent to collect such payments in respect of the Note. The Company shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes to be effected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

As provided in and subject to certain exceptions and the provisions of the Indenture, in case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of and interest on all Notes may be declared due and payable, by either the Trustee or Holders of not less than 25% in aggregate principal amount of Notes then Outstanding, and upon said declaration shall become due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal of, interest on and the consideration due upon conversion of, this Note at the time, place and rate, and otherwise on the terms prescribed herein and in the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security Register, upon

The Notes are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax payable in connection therewith to the extent provided in the Indenture.
