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

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

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

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

Section 2.13.                          Additional Transfer and Exchange Requirements .  (a)  If Notes are issued upon the transfer, exchange or replacement of Notes subject to restrictions on transfer and bearing the Transfer Restricted Note Legend, or if a request is made to remove the Transfer Restricted Note Legend on a Note, the Notes so issued shall bear the Transfer Restricted Note Legend, or the Transfer Restricted Note Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an Opinion of Counsel if requested by the Company or such Registrar, as may be reasonably required by the Company and the Registrar, that neither the Transfer Restricted Note

14

Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 or that such Notes are not “restricted” within the meaning of Rule 144; provided that no such evidence need be supplied in connection with the sale of such Note pursuant to a registration statement that is effective at the time of such sale.  Upon (i) provision of such satisfactory evidence if requested, or (ii) notification by the Company to the Trustee and Registrar of the sale of such Note pursuant to a registration statement that is effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate and deliver a Note that does not bear the Transfer Restricted Note Legend.  If the Transfer Restricted Note Legend is removed from the face of a Note and the Note is subsequently held by an Affiliate of the Company, the Transfer Restricted Note Legend shall be reinstated.

(b)           No transfer of a Note to any Person shall be effective under this Indenture or the Notes unless and until such Note has been registered in the name of such Person.

(c)           The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures.

(i)            Beneficial interests in any Transfer Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Transfer Restricted Global Note in accordance with the transfer restrictions set forth in the Transfer Restricted Note Legend.  Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same or any other Unrestricted Global Note.  No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.13(c)(i).

(ii)           In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.13(c)(i), the transferor of such beneficial interest must deliver to the Registrar an order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase.

(iii)          A beneficial interest in any Transfer Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Transfer Restricted Global Note if the transfer complies with the requirements of Section 2.13(c)(ii) and the Registrar receives a duly executed certificate substantially in the form of Exhibit D hereto.

(iv)          A beneficial interest in any Transfer Restricted Global Note may be exchanged for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note if (1) the exchange or transfer complies with the requirements of Section 2.13(c)(ii) and (2) if the Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form

15

reasonably acceptable to the Registrar to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Transfer Restricted Note Legend are no longer required in order to maintain compliance with the Securities Act.

(d)           The restrictions imposed by the Transfer Restricted Note Legend upon the transferability of any Note shall cease and terminate when such Note has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(d) under the Securities Act (or any successor provision).  Any Note as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Note for exchange to the Registrar in accordance with the provisions of this Section 2.13 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 (or any successor provision), by, if requested, an Opinion of Counsel reasonably acceptable to the Company, addressed to the Company and in form acceptable to the Company, to the effect that the transfer of such Note has been made in compliance with Rule 144 (or such successor provision), be exchanged for a new Note, of like tenor and aggregate principal amount, which shall not bear the Transfer Restricted Note Legend.

(e)           As used in Section 2.13(c) and (d), the term “transfer” encompasses any sale, pledge, transfer, hypothecation or other disposition of any Note.

(f)            This Section 2.13(f) shall apply only to Global Notes:

(i)            Notwithstanding any other provisions of this Indenture or the Notes, a Global Note shall not be exchanged in whole or in part for a Note registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Note may be exchanged for Notes registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note or such Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days, (B) the Company has provided the Depositary with written notice that it has decided to discontinue use of the system of book-entry transfer through the Depositary or any successor Depositary or (C) an Event of Default has occurred and is continuing.  Any Global Note exchanged pursuant to clauses (A) or (B) above shall be so exchanged in whole and not in part, and any Global Note exchanged pursuant to clause (C) above may be exchanged in whole or from time to time in part as directed by the Depositary.  Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note.

(ii)           Notes issued in exchange for a Global Note or any portion thereof shall be issued in definitive, fully-registered book entry form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein.  Any Global

16

Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar.  With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee.  Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Note issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

(iii)          Subject to the provisions of clause (v) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

(iv)          In the event of the occurrence of any of the events specified in clause (i) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Notes in definitive, fully registered form, without interest coupons.

(v)           Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any such Global Note, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever.  Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note.  Neither the Trustee nor any Agent Member shall have any responsibility or liability for any actions taken or not taken by the Depositary.

ARTICLE 3

REPURCHASES

Section 3.01.        Repurchase at the Option of the Holders Upon Change in Control or Termination of Trading .  (a) Upon the occurrence of a Change in Control or a Termination of Trading, each Holder shall have the right, at such Holder’s option, subject to the terms and conditions of this Article 3, to require the Company to repurchase for Cash all or any portion of such Holder’s Notes in integral multiples of $1,000 principal amount at a price (the “ Fundamental Change Repurchase Price ”) equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest (including Additional Interest), if any, to, but excluding, the Fundamental Change Repurchase Date; provided that if the Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the Interest Payment Date to which it relates, the interest accrued to the Interest Payment Date will be paid to Holders of the Notes as of the preceding Regular Record Date, and the Fundamental Change Repurchase

17

Price shall be equal to the principal amount of Notes subject to repurchase.  Upon a valid exercise of such an option, the Company will be required to repurchase the Notes on a date selected by the Company (the “ Fundamental Change Repurchase Date ”), which shall be no earlier than 20 days or later than 35 days after the date on which the Company sends the notice contemplated by Section 3.01(b), subject to satisfaction by or on behalf of the Holder of the requirements set forth in Section 3.01(c).

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

(i)            any person or group, other than the Company, its Subsidiaries or any employee benefit plan of the Company or its Subsidiaries, files a Schedule 13D or Schedule TO (or any successor schedule, form or report) pursuant to the Exchange Act disclosing that such person has become the direct or indirect beneficial owner of shares with a majority of the total voting power of all of the Company’s outstanding Voting Securities, unless such beneficial ownership (a) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (b) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act;

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

(iii)          the holders of Common Stock approve any plan or proposal for the liquidation or dissolution of the Company.

For purposes of defining a Change in Control:

(A)          the term “ person ” and the term “ group ” have the meanings given by Section 13(d) and 14(d) of the Exchange Act or any successor provisions;

(B)           the term “ group ” includes any group acting for the purpose of acquiring, holding or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act or any successor provision; and

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

18

Notwithstanding the foregoing, it will not constitute a Change in Control if at least 90% of the consideration for Common Stock (excluding Cash payments for fractional shares and Cash payments made in respect of dissenters’ appraisal rights) in the transaction or transactions constituting the Change in Control consists of Common Stock traded on a United States national securities exchange, or which will be so traded when issued or exchanged in connection with the Change in Control, and as a result of such transaction or transactions the Notes become convertible solely into the consideration that holders of Common Stock receive in such transaction, other than any Cash in lieu of fractional shares.

(b)           On or before the 15th day after the occurrence of a Change in Control or Termination of Trading, the Company will deliver a written notice of Change in Control or Termination of Trading, as applicable, to the Trustee and to each Holder at their addresses shown in the register of the Registrar (and to beneficial owners as required by applicable law).  The notice shall include a form of Fundamental Change Repurchase Notice to be completed by the Holder and shall state:

(i)            the events causing a Change in Control or Termination of Trading, as applicable;

(ii)           the date of such Change in Control or Termination of Trading, as applicable;

(iii)          the last date on which the repurchase right may be exercised;

(iv)          the Fundamental Change Repurchase Price;

(v)           the Fundamental Change Repurchase Date;

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

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

(viii)        whether a Change in Control constitutes a Make-Whole Change in Control;

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

(x)            the procedures a Holder must follow to exercise rights under this Section 3.01.

(c)           A Holder may exercise its rights specified in Section 3.01 by delivery of a written notice (a “ Fundamental Change Repurchase Notice ”) to the Paying Agent at any time

19

prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date.  The Fundamental Change Repurchase Notice shall state:

(i)            if Certificated Notes have been issued, the certificate number of the Notes (or if the Holder’s Notes are Global Notes, such Holder’s notice must comply with the Applicable Procedures);

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

(iii)          that such Notes shall be repurchased by the Company pursuant to the terms and conditions specified in this Article 3.

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

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

Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.01 shall be consummated by the delivery of the consideration to be received by the Holder (together with accrued and unpaid interest (including any Additional Interest) to but not including the Fundamental Change Repurchase Date) on or prior to the later of the Fundamental Change Repurchase Date and the time of delivery of the Note to the Paying Agent in accordance with this Section 3.01.

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

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

No Notes may be repurchased by the Company at the option of Holders upon a Change in Control or a Termination of Trading if the principal amount of the Notes has been accelerated (other than as a result of a default in the payment of the Fundamental Change Repurchase Price with respect to the Notes), and such acceleration has not been rescinded, on or prior to the date on which such repurchase is to be consummated.  The Paying Agent will promptly return to the

20

respective Holders thereof any Notes (x) with respect to which a Fundamental Change Repurchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of acceleration described in the immediately preceding sentence in which case, upon such return, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

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

(a)           On each of February 15, 2018 and February 15, 2023 (each, an “ Optional Repurchase Date ”), each Holder shall have the right, at such Holder’s option, subject to the terms and conditions of this Article 3, to require the Company to repurchase for Cash all or any portion of such Holder’s Notes in integral multiples of $1,000 principal amount at a price (the “ Optional Repurchase Price ”) equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest (including Additional Interest), if any, to, but excluding, the applicable Optional Repurchase Date; provided that if such Optional Repurchase Date is after a Regular Record Date and on or prior to the Interest Payment Date to which it relates, the interest accrued to the Interest Payment Date will be paid to Holders of the Notes as of the preceding Regular Record Date, and the Optional Repurchase Price shall be equal to the principal amount of Notes subject to repurchase.

(b)           On or before the 20th Business Day prior to each Optional Repurchase Date, the Company shall deliver or cause to be delivered to all Holders of record on such date at their addresses shown in the Register of the Registrar (and to beneficial owners as required by applicable law) an Optional Repurchase Notice as set forth in Section 3.02(c).  No failure of the Company to give the foregoing notices and no defect therein shall limit the repurchase rights of Holders or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.02.

(c)           For Notes to be so repurchased at the option of the Holder, the Holder must deliver to the Paying Agent, at any time during the period beginning at 9:00 a.m., New York City time, on the date that is 20 Business Days prior to the applicable Optional Repurchase Date and ending at the Close of Business on the Business Day immediately preceding such Optional Repurchase Date, (i) a notice (the “ Optional Repurchase Notice ”) in the form set forth on the reverse of the Notes duly completed (if the Notes are certificated) or comply with Applicable Procedures (if the Notes are represented by a Global Note) together with (ii) such Notes duly endorsed for transfer (if the Notes are certificated) or book-entry transfer of such Notes (if such Notes are represented by a Global Note).  The delivery of such Notes to the Paying Agent with, or at any time after delivery of, the Optional Repurchase Notice (together with all necessary endorsements), at the office of the Paying Agent shall be a condition to the payment by the Company to the Holder of the Optional Repurchase Price, therefor; provided that such Optional Repurchase Price shall be so paid pursuant to this Section 3.02 only if the Notes so delivered to the Paying Agent shall conform in all respects to the description thereof in the Optional Repurchase Notice.  All questions as to the validity, eligibility (including time of receipt) and acceptance of any Notes for repurchase shall be determined in good faith by the Company, whose determination shall be final and binding absent manifest error.  The Optional Repurchase Notice, shall state:

21

(i)            the certificate numbers of the Notes to be repurchased, if they are Certificated Notes;

(ii)           the portion of the principal amount of a Holder’s Notes to be repurchased, which must be in integral multiples of $1,000 principal amount; and

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

(d)           The Company shall repurchase from the Holder thereof, pursuant to this Section 3.02, a portion of a Note, if the principal amount of such portion is in integral multiples of $1,000 principal amount.

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

(f)            Any repurchase by the Company contemplated pursuant to the provisions of this Section 3.02 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the applicable Optional Repurchase Date and the time of the book-entry transfer or delivery of the Notes, as the case may be.

Section 3.03.        Effect of Repurchase Notice .  (a) Upon receipt by the Paying Agent of the Fundamental Change Repurchase Notice specified in Section 3.01(c) or the Optional Repurchase Notice specified in Section 3.02(c) (each of the foregoing, a “ Repurchase Notice ”), the Holder of the Note in respect of which such Repurchase Notice was given shall (unless such Repurchase Notice is withdrawn as specified in this Section 3.03) thereafter be entitled to receive solely the Fundamental Change Repurchase Price or Optional Repurchase Price (each of the foregoing, a “ Repurchase Price ”), as applicable, and any accrued and unpaid interest (including any Additional Interest) to but not including the Fundamental Change Repurchase Date or Optional Repurchase Date (each of the foregoing, a “ Repurchase Date ”), as applicable, with respect to such Note.  Such Repurchase Price shall be paid to such Holder, subject to receipt of funds by the Paying Agent, on or prior to the later of (x) the Repurchase Date with respect to such Note ( provided the conditions in Section 3.01(c) or Section 3.02(c), as applicable, have been satisfied) and (y) the time of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.01(c) or Section 3.02(c), as applicable.  Notes in respect of which a Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after the date of the delivery of such Repurchase Notice unless such Repurchase Notice has first been validly withdrawn as specified in this Section 3.03.

(b)           A Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent at any time prior to the Close of Business on the Business Day immediately preceding the Repurchase Date.  If a Repurchase Notice is withdrawn, the Company will not be obligated to repurchase such Notes listed in the Repurchase Notice.  Such notice of withdrawal shall state:

(i)            the principal amount being withdrawn;

22

(ii)           if Certificated Notes are to be withdrawn, the certificate numbers of the Notes being withdrawn (or, if Global Notes or a portion thereof are to be withdrawn, such Holder’s notice must comply with the Applicable Procedures);

Section 3.04.        Deposit of Repurchase Price .  Prior to 12:00 p.m., New York City time, on or prior to the Repurchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary of the Company or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of money (in immediately available funds if deposited on such Trading Day) sufficient to pay the aggregate Repurchase Price of all the Notes or portions thereof which are to be repurchased as of the Repurchase Date.

If the Paying Agent holds money sufficient to pay the Repurchase Price with respect to the Notes to be repurchased on the Repurchase Date in accordance with the terms of this Indenture, then, immediately on and after the Repurchase Date, those Notes shall cease to be outstanding, interest (including any Additional Interest) on such Notes shall cease to accrue, whether or not the Notes are delivered to the Paying Agent, and all other rights of the Holders of such Notes shall terminate, other than the right to receive the Repurchase Price upon delivery of such Notes.

Section 3.05.        Notes Repurchased in Part .  Any Note which is to be repurchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Note, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not repurchased.

First: to the Trustee for all amounts due under Section 7.07 hereof;

Section 6.11.        Restoration of Rights and Remedies .  If the Trustee or any Holder has instituted a proceeding to enforce any right or remedy under this Indenture and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the Holder, then, subject to any determination in the proceeding, the Company, the Trustee and the Holders will be restored severally and respectively to their former positions

30

hereunder and thereafter all rights and remedies of the Company, the Trustee and the Holders will continue as though no such proceeding had been instituted.

Section 6.12.        Undertaking for Costs .  In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys fees, against any party litigant (other than the Trustee) in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant.  This Section does not apply to a suit by a Holder to enforce payment of (a) principal of or interest (including any Additional Interest) on any Note on the respective due dates, (b) the Change of Control Purchase Price on the Change of Control Repurchase Date, (c) the Redemption Price on the Redemption Date, (d) the Cash and shares of Common Stock, if any, due upon conversion of a Note or (e) a suit by Holders of more than 10% in principal amount of the outstanding Notes.

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

Section 6.15.        Additional Interest; Failure to File ; Delegending .  (a) Notwithstanding anything in this Article 6, the Company may, at its option, elect that the sole remedy for an Event of Default relating to its failure to comply with its obligations described under Section 4.04 or its failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act will for the first 180 days after the occurrence of such an Event of Default (which will be the 60th day after written notice is provided to the Company in accordance with Section 6.01(e)), consist exclusively of the right to receive additional interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes (the “ Additional Interest ”).  If the Company elects to pay Additional Interest, such Additional Interest will be payable on all outstanding Notes from and including the date on which such Event of Default first occurs to but excluding the 181st day thereafter (or such earlier date on which the Event of Default relating to a failure to comply with such requirements has been cured or waived).  On the 181st day after such Event of Default (if such violation is not cured or waived prior to such 181st day), the Notes will be subject to acceleration as provided in Section 6.02.  In the event the Company does not elect to pay the Additional Interest upon any such Event of Default in accordance with this Section 6.15, the Notes will be subject to acceleration as provided in Section 6.02.  This Section 6.15 shall not affect the rights of Holders if any other Event of Default occurs under this Indenture.

31

In order elect to pay the Additional Interest as the sole remedy during the first 180 days after the occurrence of any Event of Default relating to the failure to comply with the reporting obligations in accordance with the preceding paragraph, the Company shall notify all Holders and the Trustee and Paying Agent of such election in writing prior to the Close of Business on the date on which such Event of Default occurs.  If the Company fails to timely give such notice, the Notes will be immediately subject to acceleration as provided in Section 6.02.

(b)           If, at any time during the period beginning six months from the last date of original issuance of the Notes (including the last date of issuance of additional Notes pursuant to the exercise of the Initial Purchasers’ option to purchase additional Notes) (such date, the “ Last Original Issuance Date ”) and ending on the one-year anniversary of the Last Original Issuance Date (the “ Free Trade Date ”), the Company fails to make available adequate current public information in accordance with Rule 144(c) of the Securities Act, the Company shall pay Additional Interest on the Notes, accruing from and including the first day on which the Company fails to make available adequate current public information in accordance with Rule 144(c) and continuing until the earlier of (i) the Free Trade Date and (ii) the date on which the Company corrects such failure. During the first 90 days on which such Additional Interest is payable, such Additional Interest shall accrue at a rate of 0.25% per annum; thereafter, such Additional Interest shall accrue at a rate of 0.50% per annum.

(c)           In addition, if the Company fails to cause the Notes or any shares of Common Stock issuable upon conversion of the Notes to become Freely Tradable on and at all times after the Free Trade Date (or the next succeeding Business Day if the Free Trade Date is not a Business Day), the Company shall pay Additional Interest on the Notes accruing from and including the Free Trade Date and until the date on which the Notes and any shares of Common Stock issuable upon the conversion of the Notes become Freely Tradable. During the first 90 days on which such Additional Interest is payable, such Additional Interest will accrue at a rate of 0.25% per annum; thereafter, such Additional Interest will accrue at a rate of 0.50% per annum.

(d)           Notwithstanding anything herein to the contrary, in no event will the combined rate of any Additional Interest payable under this Section 6.15 exceed 0.50% per annum.

(e)           Additional Interest shall be payable at the same time, in the same manner and to the same Persons as ordinary interest.

(f)            If the Company is required to pay Additional Interest to Holders, the Company shall provide a direction or order in the form of a written notice to the Trustee (and if the Trustee is not the Paying Agent, to the Paying Agent) of the Company’s obligation to pay such Additional Interest no later than three Business Days prior to the date on which any such Additional Interest is scheduled to be paid.  Such notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the Trustee (or, if the Trustee is not the Paying Agent, to the Paying Agent) to make payment to the extent it receives funds from the Company to do so.  The Trustee shall not at any time be under any duty or responsibility to any Holder to determine whether the Additional Interest is payable, or with

32

respect to the nature, extent or calculation of the amount of the Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

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

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

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.07 shall survive and, if money shall have been deposited with or Common Stock shall have been delivered to the Trustee pursuant to clause (a) of this Section, the provisions of Section 2.03, Section 2.04, Section 2.05, Section 2.06, Section 2.07, Section 2.12, Section 3.01, Article 5, Article 10 and this Article 8, shall survive and the Company shall be required to make all payments and deliveries required by such Sections or

37

Articles, as the case may be, irrespective of any prior satisfaction and discharge until the Notes have been paid in full.

Section 8.02.                          Application of Trust Money .  Subject to the provisions of Section 8.03, the Trustee or a Paying Agent shall hold in trust, for the benefit of the Holders, all money, Common Stock or other consideration paid or delivered to it, as the case may be, pursuant to Section 8.01 and shall apply such money, Common Stock or other consideration in accordance with this Indenture and the Notes to the payment of the principal amount of (including the relevant Repurchase Price or Redemption Price) and interest (including any Additional Interest) on the Notes or delivery of Cash and shares of Common Stock, if any, issuable upon conversion of the Notes.

ARTICLE 9

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

(a)                                   to cure any ambiguity, omission, defect or inconsistency in this Indenture or the Notes or to conform this Indenture or the Notes to the section entitled “Description of Notes” contained in the Offering Memorandum;

(b)                                  to evidence a successor to the Company and the assumption by that successor of the obligations of the Company under this Indenture in accordance with Article 5 or Section 10.09, including to provide for the adjustments to the Conversion Rate as set forth in Section 10.09;

(e)                                   to make any change to comply with the Trust Indenture Act, or any amendment thereto; and

(f)                                     to make any change that does not adversely affect the rights of any Holder of the Notes.

Section 9.02.                          Amendments With Consent of Holders .  (a) Except as otherwise provided in Section 6.07 or paragraph (b), the Company and the Trustee may amend this Indenture and the Notes with the written consent of the Holders of at least a majority in principal amount of the outstanding Notes, and the Holders of a majority in principal amount of the outstanding Notes by written notice to the Trustee may, on behalf of the Holders of such Notes, waive any existing or past default under this Indenture and its consequences, except an uncured default (i) in the payment of the principal amount, or accrued and unpaid interest (including any Additional Interest), with respect to any Note, (ii) the Repurchase Price with respect to any Note (iii) the Redemption Price with respect to any Note, (iv) in the payment or delivery of the Cash and shares of Common Stock, if any, due upon conversion or redemption of the Notes or (v) in respect of any provision that under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected.

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

39

(i)                                      reduce the principal amount of, or premium or interest payment on, any Note, or reduce the Repurchase Price or Redemption Price on any Note;

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

(iii)                                change the Maturity Date of any Note;

(iv)                               change the ranking of the Notes;

(v)                                  make any change that adversely affects the right of a Holder to convert any Note;

(vi)                               make any change that adversely affects the right of a Holder to require the Company to repurchase a Note upon the occurrence of a Change in Control or Termination of Trading or on an Optional Repurchase Date;

(vii)                            impair the right to convert or receive payment with respect to the Notes or the right to institute suit for the enforcement of any payment with respect to, or conversion of, the Notes; or

(viii)                         change the provisions in this Indenture that relate to modifying or amending the provisions of this Indenture.

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

(d)                                  An amendment, supplement or waiver delivered under this Section will become effective on receipt by the Trustee of written consents (including consents delivered in accordance with the Applicable Procedures with respect to Global Notes) from the Holders of the requisite percentage in principal amount of the outstanding Notes.  After an amendment, supplement or waiver under this Section becomes effective, the Company will send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver.  The Company will send supplemental indentures to Holders upon request.  Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.

Section 9.03.                          Effect of Consent .  (a) After an amendment, supplement or waiver becomes effective, it will bind every Holder unless it is of the type requiring the consent of each Holder affected.  If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement or waiver shall bind each Holder that has consented to it and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting Holder.

(b)                                  If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of the changed terms on the Note and return it to the Holder, or exchange it

40

for a new Note that reflects the changed terms.  The Trustee may also place an appropriate notation on any Note thereafter authenticated.  However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion.

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

Section 9.05.                          Payments for Consents .  The Company shall not, and shall not permit or suffer any of its Subsidiaries or Affiliates to, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or agreed to be paid to all Holders of the Notes that consent, waive or agree to amend such term or provision within the time period set forth in the solicitation documents relating to the consent, waiver or amendment.

ARTICLE 10

CONVERSION

Section 10.01.                   Conversion Privilege .  (a) Subject to and upon compliance with the provisions of this Article 10, a Holder 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 Holder’s Notes at any time prior to the Close of Business on the Business Day immediately preceding the Maturity Date, upon the occurrence of any of the events set forth in clauses (i) through (ix) of Section 10.01(b), at a Conversion Rate (the “ Conversion Rate ”) of 91.4808 shares of Common Stock per $1,000 principal amount of Notes.  Upon conversion of any Notes, the Company shall deliver to the converting Holder Cash up to the aggregate principal amount of Notes to be converted and shares of Common Stock, Cash or a combination thereof in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the Notes being converted as described in Section 10.03 and subject to adjustment as set forth in this Article 10 (the Company’s obligation to deliver such consideration being herein called the “ Conversion Obligation ”).

(b)                                  A Holder may convert its Notes prior to the Close of Business on the Business Day immediately preceding the Maturity Date, upon the occurrence of any of the events set forth below:

(i)                                      during any calendar quarter commencing at any time after March 7, 2013, and only during such calendar quarter, if the Closing Price of Common Stock for at least 20 Trading Days in the period of 30 consecutive Trading Days ending on the last Trading Day of

41

the preceding calendar quarter exceeds the Conversion Trigger Price (as defined in Section 10.01(c)) on the last Trading Day of such preceding calendar quarter;

(ii)                                   during the five Business Day period immediately after any five consecutive Trading Day period in which the Trading Price per $1,000 principal amount of Notes for each Trading Day during that five-day period was less than 98% of the product of the Closing Price of Common Stock on such Trading Day and the then Applicable Conversion Rate for the Notes on such Trading Day, subject to compliance with the procedures and conditions described in Section 10.01(d) concerning the Trustee’s obligation to make a Trading Price determination (the “ Trading Price Condition ”);

(iii)                                if the Company elects to distribute to all holders of Common Stock rights, options or warrants entitling all holders of Common Stock to subscribe for or purchase Common Stock, for a period expiring within 60 days after the record date for such distribution, at less than the average of the Closing Prices of Common Stock for the five consecutive Trading Days ending on the date immediately preceding the first public announcement of such distribution, during the period beginning on, and including, the date the Company provides notice to Holders of such distribution as set forth in Section 10.01(e) and ending on, and including, the earlier of (x) the Close of Business on the Business Day prior to the Ex-Date for such distribution and (y) the Company’s announcement that such distribution will not take place;

(iv)                               if the Company elects to distribute to all holders of Common Stock Cash, debt securities (or other evidence of indebtedness) or other assets (excluding dividends or distributions described in Section 10.07(a)), which distribution, together with all other such distributions within the preceding twelve months, has a per share value, as determined by the Board of Directors, exceeding 15% of the average of the Closing Prices of Common Stock for the five consecutive Trading Days ending on the date immediately preceding the first public announcement of such distribution, during the period beginning on, and including, the date the Company provides notice to Holders of such distribution as set forth in Section 10.01(e) and ending on, and including, the earlier of (x) the Close of Business on the Business Day prior to the Ex-Date for such distribution and (y) the Company’s announcement that such distribution will not take place;

(v)                                  if a Termination of Trading occurs, during the period from, and including, the earlier of (i) the date the applicable securities exchange announces that a Termination of Trading will occur and (ii) the effective date of the Termination of Trading, to, and including, the related Repurchase Date;

(vi)                               if a Make-Whole Change in Control that does not constitute a Change in Control occurs or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of the Company’s assets, pursuant to which Common Stock would be converted into Cash, securities or other assets, during the period from, and including, the date that is 25 Business Days prior to the anticipated effective date of the transaction, to, and including, the date that is 35 Trading Days after the actual closing date of such transaction;

42

(vii)                            if a Change of Control occurs, during the period from, and including, the date that is 25 Business Days prior to the anticipated effective date of the transaction, to, and including, the related Repurchase Date;

(viii)                         for Notes that have been called for redemption, at any time prior to the Close of Business on the Business Day immediately preceding the Redemption Date, even if the Notes are not otherwise convertible at such time; or

(ix)                                 at any time on or after November 15, 2032 until the Close of Business on the Business Day immediately preceding the Maturity Date.

(c)                                   The “ Conversion Trigger Price ” shall equal 130% of the Conversion Price.  The Conversion Trigger Price will initially equal $14.209 and shall be automatically adjusted whenever the Conversion Price is adjusted as a result of an adjustment in the Conversion Rate pursuant to this Article 10.  The Company will determine at the beginning of each calendar quarter commencing at any time after March 7, 2013, whether the Notes are convertible as a result of the price of Common Stock exceeding the Conversion Trigger Price in accordance with Section 10.01(b)(i) and will notify the Conversion Agent and the Trustee.

(d)                                  In connection with any conversion upon satisfaction of the Trading Price Condition as set forth in Section 10.01(b)(ii) above, the Trustee shall have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of the Notes at such time would be less than 98% of the product of the Closing Price of Common Stock and the then Applicable Conversion Rate.  At such time, the Company shall instruct the Trustee to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Closing Price of Common Stock and the then Applicable Conversion Rate.  If the Company does not, when it is obligated to, make a request to the Trustee to determine the Trading Price per $1,000 principal amount of Notes, or if the Company makes such request to the Trustee, but the Trustee does not or cannot make such determination, then the Trading Price per $1,000 principal amount of Notes will be deemed to be less than 98% of the product of the Closing Price of Common Stock and the then Applicable Conversion Rate on each day the Company or the Trustee fails to do so.  If the Trading Price Condition has been met, the Company shall so notify the Holders and the Trustee.  If, at any point after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of the product of the Closing Price of Common Stock and the then Applicable Conversion Rate, the Company shall so notify the Holders and the Trustee.

(e)                                   Upon the first public announcement of any distribution described in Section 10.01(b)(iii) or Section 10.01(b)(iv), the Company shall notify the Holders at least 35 Business Days prior to the Ex-Date for such distribution by (i) issuing a press release and using its reasonable efforts to post such information on its website or otherwise publicly disclose this information or (ii) providing written notice to Holders by mailing such notice to Holders at their address in the Register (in the case of a Certificated Note), or through the facilities of the Depositary (in the case of a Global Note).

43

(f)                                     In connection with the transactions described in Section 10.01(b)(v), (vi) or (vii), the Company shall notify the Holders and the Trustee (i) in the case of a Change in Control or a Make-Whole Change in Control, as promptly as practicable following the date the Company publicly announces such transaction, which shall be at least 25 Business Days prior to the anticipated effective date in the case of transactions to which the Company is a party, and (ii) in the case of a Termination of Trading, the earlier of (x) the day immediately following the date the applicable securities exchange announces that a termination of trading will occur and (y) the effective date of a Termination of Trading by (A) issuing a press release and using its reasonable efforts to post such information on its website or otherwise publicly disclose this information or (B) providing written notice to Holders by mailing such notice to Holders at their address in the Register (in the case of a Certificated Note), or through the facilities of the Depositary (in the case of a Global Note).

(g)                                  Upon determining that Holders are entitled to convert their Notes in accordance with the provisions set forth in Section 10.01(b), the Company shall promptly (i) issue a press release and use its reasonable efforts to post such information on its website or otherwise publicly disclose such information or (ii) provide written notice to Holders by mailing such notice to Holders at their address in the Register (in the case of a Certificated Note), or through the facilities of the Depositary (in the case of a Global Note).

(h)                                  Holders shall not have the right to convert their Notes pursuant to Section 10.01(b)(iii) or Section 10.01(b)(iv) if in connection with the distribution described in Section 10.01(b)(iii) or Section 10.01(b)(iv) that gives rise to a right to convert their Notes, such Holders are entitled to participate (as a result of holding the Notes, and at the same time as holders of Common Stock participate) in the distribution described in such Section as if such Holders held a number of shares of Common Stock equal to the Applicable Conversion Rate on the Ex-Date for such distribution, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder, without having to convert their Notes.

Section 10.02.                   Conversion Procedures; Conversion Settlement .  (a)  To convert a Note that is represented by a Certificated Note, a Holder must (1) complete and manually sign a Conversion Notice, a form of which is on the back of the Note, and deliver such Conversion Notice to the Conversion Agent, (2) surrender the Note to the Conversion Agent, (3) if required, furnish appropriate endorsement and transfer documents, (4) if required, pay all transfer or similar taxes and (5) if required, pay Cash equal to amount of interest due on the next Interest Payment Date for such Note.  If a Holder holds a beneficial interest in a Global Note, to convert such beneficial interest, such Holder must comply with requirements (4) and (5) as set forth in the immediately preceding sentence and comply with the Applicable Procedures of the Depositary for converting a beneficial interest in a Global Note.  The first date on which all of the requirements set forth in the first sentence of this Section 10.02 (in the case of a Certificated Note) or the second sentence of this Section 10.02 (in the case of a Global Note or a beneficial interest therein) have been satisfied is referred to in this Indenture as the “ Conversion Date .”  The Conversion Agent shall, within one (1) Business Day of any Conversion Date, provide notice to the Company, as set forth in Section 13.02, of the occurrence of such Conversion Date.

44

(b)                                  Subject to Section 10.09 and Section 10.10, the Company will deliver the consideration due in respect of conversion on the third Business Day immediately following the last Trading Day of the relevant Observation Period.

(c)                                   A Holder receiving Common Stock upon conversion shall not be entitled to any rights as a holder of Common Stock, including, among other things, the right to vote and receive dividends and notices of stockholder meetings, until the Close of Business on the last Trading Day of the Observation Period.

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

(e)                                   Notwithstanding Section 10.02(d), if Notes are converted after a Regular Record Date but prior to the next succeeding Interest Payment Date, Holders of such Notes at the Close of Business on such Regular Record Date will receive the interest payable (including Additional Interest) on such Notes on the corresponding Interest Payment Date notwithstanding the conversion.  Such Notes, upon surrender for conversion, must be accompanied by Cash equal to the amount of interest (including any Additional Interest) payable on such Interest Payment Date on the Notes so converted; provided that no such payment need be made (1) if the Company has specified a Redemption Date that is after a Regular Record Date but on or prior to the next succeeding Interest Payment Date, (2) if the Company has specified a Repurchase Date that is after a Regular Record Date but on or prior to the next succeeding Interest Payment Date, (3) with respect to any Notes converted after the Regular Record Date immediately preceding February 15, 2018 or February 15, 2023, or (4) to the extent of any Defaulted Interest that exists at the time of conversion with respect to such Note.

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

(g)                                   Upon surrender of a Note that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Note in an authorized denomination equal in principal amount to the unconverted portion of the Note surrendered.

Section 10.03.                   Settlement Upon Conversion .  (a)  Subject to Section 10.09, upon conversion of any Note, the Company shall pay or deliver, as the case may be, to the converting

45

Holder, in respect of each $1,000 principal amount of Notes being converted, a “ Settlement Amount ” equal to the sum of the Daily Settlement Amounts for each of the 20 Trading Days during the relevant Observation Period for such Note, together with Cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 10.04.

(b)                                  “ Daily Settlement Amount ,” for each of the 20 consecutive Trading Days during the applicable Observation Period, shall consist of (i) Cash in an amount equal to the lesser of (x) $50.00 and (y) the Daily Conversion Value on such Trading Day; and (ii) if the Daily Conversion Value on such Trading Day exceeds $50.00, the Daily Net Settlement Amount.

(c)                                   All conversions occurring on or after the 24th Scheduled Trading Day immediately preceding the Maturity Date shall be settled using the same forms and amounts of consideration.  Before the 24th Scheduled Trading Day immediately preceding the Maturity Date, the Company shall use the same forms and amounts of consideration for all conversions based on a single Observation Period, but the Company shall not have any obligation to use the same forms and amounts of consideration with respect to conversions that occur based on different Observation Periods.

(d)                                  With respect to any conversion of Notes, subject to subsection (c) of this Section 10.03, the Company may irrevocably elect to settle all or a portion of the remainder, if any, of its Conversion Obligation in excess of the aggregate principal portion of the Notes being converted in Cash by informing the Trustee, the converting Holders, through the Trustee, and the Depositary no later than the Close of Business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions occurring on or after the 24th Scheduled Trading Day immediately preceding the Maturity Date, no later than the 24th Scheduled Trading Day immediately preceding the Maturity Date), and the Company shall indicate in such notice the percentage of the remainder, if any, of the Company’s Conversion Obligation in excess of the aggregate principal portion of the Notes being converted that will be paid in Cash (the “ Cash Percentage ”).

(e)                                   The Daily Settlement Amounts (if applicable), the Daily Net 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, the Daily Net Settlement Amounts (if applicable) or the Daily Conversion Values, as the case may be, and the amount of Cash, if any, deliverable in lieu of any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts, the Daily Net Settlement Amounts (if applicable) or the Daily Conversion Values, as the case may be, and the amount of Cash, if any, deliverable in lieu of fractional shares of Common Stock.  In calculating the Daily Settlement Amounts (if applicable) and the Daily Net Settlement Amounts (if applicable), the Conversion Rate on any day shall be appropriately adjusted to take into account the occurrence on or before such Trading Day of any event that would require an adjustment to the Conversion Rate as set forth in Section 10.07.  The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

Section 10.04.                   Fractional Share .  The Company will not issue a fractional share of Common Stock upon conversion of a Note.  Instead, the Company shall pay Cash in lieu of

fractional shares based on the Closing Price of Common Stock on the last Trading Day of the relevant Observation Period.

Section 10.05.                   Taxes on Conversion .  If a Holder converts a Note, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon the conversion.  However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name.  The Conversion Agent may refuse to deliver the certificates representing Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because Common Stock is to be delivered in a name other than the Holder’s name.

Section 10.06.                   Company to Provide Common Stock .  The Company shall, from time to time as may be necessary, reserve out of its authorized but unissued shares of Common Stock a sufficient number of shares of Common Stock to permit the delivery in respect of all outstanding Notes of the number of shares of Common Stock due upon conversion.

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

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

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

Section 10.07.                   Adjustment to Conversion Rate .  The Conversion Rate shall be adjusted, at any time and from time to time while any of the Notes are outstanding, by the Company if any of the following events occur.

(a)                                  If the Company issues dividends or makes distributions on Common Stock payable in shares of Common Stock, or if the Company subdivides, combines or reclassifies shares of Common Stock, the Conversion Rate shall be adjusted based on the following formula:
