Section 2.04      Registrar, Paying Agent and Conversion Agent . The Company shall maintain within the continental United States an office or agency where Notes may be presented for registration of transfer or for exchange ( “Registrar” ), an office or agency in where Notes may be presented for payment ( “Paying Agent” ), an office or agency where Notes may be presented for conversion ( “Conversion Agent” ). The Registrar shall keep a register for the recordation of, and shall record, the names and addresses of Holders of the Notes, the Notes held by each Holder and the transfer, exchange and conversion of Notes (the “Register” ). The entries in the Register shall

be conclusive, and the parties may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Holder hereunder for all purposes of this Indenture. The Company may have one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term Paying Agent includes any such additional paying agents. The term Conversion Agent includes any such additional conversion agents.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent, Conversion Agent or co-registrar not a party to this Indenture, which (i) shall implement the provisions of this Indenture relating to such agent and (ii) in the case of the Paying Agent, shall include the provisions set forth in Section 4.05 . The Company shall promptly notify the Trustee of the name and address of any such agent, and of any change therein. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, any presentations and surrenders required to be made by, or at the office of, any such agent may be made or served at the Corporate Trust Office or in accordance with Section 14.01 ; provided that the Trustee shall be entitled to appropriate compensation therefor pursuant to Section 7.06 . The Company may act as Paying Agent, Registrar, Conversion Agent or co-registrar.

The Company initially appoints the Trustee as the Paying Agent, the Conversion Agent, and the Registrar, in connection with the Notes, and the Corporate Trust Office to be such office or agency of the Company for the aforesaid purposes. The Company may at any time rescind the designation of the Paying Agent, Conversion Agent or the Registrar or approve a change in the location through which any of them acts; provided that the Paying Agent, Conversion Agent and Registrar must be located within the continental United States.

Section 2.05     Holder Lists . The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, promptly after each Record Date, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

Section 2.06     Transfer and Exchange .

(a)    Subject to Section 2.11 hereof, upon surrender for registration of transfer of any Note, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Holder or such Holder’s attorney-in-fact duly authorized in writing, at the office or agency of the Company-designated Registrar or co-Registrar pursuant to Section 2.04 , (i) the Company shall execute, and the Trustee (or any authenticating agent) shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations, of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture and (ii) the Registrar shall record the information required pursuant to Section 2.04 regarding the designated transferee or transferees in the Register. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co- Registrar or the Paying Agent for any registration of transfer or exchange of Notes, but the Company may require a Holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for registration of transfer or exchange.

The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of any Note (x) surrendered for conversion or (y) in respect of which a Fundamental Change Purchase Notice has been given and not validly withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of a Note to be converted or purchased in part by the Company, the portion of such Note not to be so converted or purchased).

(b)      Notwithstanding any provision to the contrary herein, so long as a Global Note remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Note, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b) . Transfers of a Global Note shall be limited to transfers of such Global Note to the Depositary, to nominees of the Depositary or to a successor of the Depositary or such successor’s nominee.

(c)      Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such registration shall be noted on the Register.

(d)      Any Registrar appointed pursuant to Section 2.04 shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Notes upon transfer or exchange of Notes.

(e)     Transfer Restrictions .

(i)    Every Note that bears or is required under this Section 2.06(e) to bear the Restricted Securities Legend (the “Restricted Notes” ) shall be subject to the restrictions on transfer set forth in this Section 2.06(e) and such legend unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Note, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. If a request is made to remove the Restricted Securities Legend from any Restricted Note prior to the Resale Restriction Termination Date, the legend shall not be removed unless there is delivered to the Company and the Registrar such certificates, legal opinions and other information as they may reasonably require confirming that such Notes, upon such transfer, will not be “restricted” within the meaning of Rule 144. In such a case, upon (1) provision of such certificates, legal opinions and/or other information, or (2) 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, pursuant to a Company Order, shall authenticate and deliver a Note that does not bear the Restricted Securities Legend.

(ii)    Except as provided elsewhere in this Indenture, until the later of (x) the date that is one year after the Original Issuance Date or such shorter period of time as permitted by Rule 144 or any successor provision thereto and (y) such other date as may be required by applicable law (such date the “Resale Restriction Termination Date” ), any certificate evidencing such Notes (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the Restricted Stock Legend, if applicable) shall bear the Restricted Securities Legend unless (I) such Notes have been transferred (1) under a registration statement that has been declared effective under the Securities Act, or (2) in accordance with Rule 144, or (II) such

requirement is waived by the Company. The Company shall notify the Trustee of any Resale Restriction Termination Date. From and after the Resale Restriction Termination Date, the restrictions specified in the Restricted Securities Legend shall be deemed eliminated.

(iii)      No transfer of any Restricted Note will be registered by the Registrar unless the applicable box on the Form of Transfer Certificate attached to such Restricted Note has been checked and such certificates, legal opinions and other information as reasonably required by the Registrar or Company confirming that the applicable condition to transfer has been satisfied have been provided.

(f)      Legends on the Common Stock. Except as provided elsewhere in this Indenture (including, without limitation, Section 2.06(i) below), until the later of (x) the Scheduled Free Trade Date and (y) the date that is three months after the holder of such shares of Common Stock ceases to be an Affiliate of the Company (if applicable), any stock certificate representing shares of the Common Stock issued upon conversion of any Notes shall bear the Restricted Stock Legend unless (A) such Notes or such Common Stock, as applicable, has been transferred (i) under a registration statement that has been declared effective under the Securities Act; or (ii) in accordance with Rule 144 under the Securities Act or (B) such requirement is waived by the Company.

(g)      The Company shall not permit any of its Affiliates to sell any Note or Common Stock issued upon the conversion of a Note, unless upon such resale such security will no longer be a “restricted security” (as defined in Rule 144 under the Securities Act). If the Restricted Securities Legend is removed from the face of a Note and the Note is subsequently held by an Affiliate of the Company, the Restricted Securities Legend shall be reinstated.

(h)      Any Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to the Registrar in accordance with the provisions of this Section 2.06 , be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restricted Securities Legend and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the custodian for the Depositary (or its nominee) in writing to so surrender any Global Note as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, such custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the Restricted Securities Legend and shall not be assigned a restricted CUSIP number.

(i)      Notwithstanding anything contained herein to the contrary, neither the Trustee nor the Registrar shall be responsible for ascertaining whether any transfer complies with the registration provisions of or exemptions from the Securities Act, applicable state securities laws, ERISA (or, in the case of a governmental plan or a church plan (as described in ERISA Sections 3(32) and 3(33), respectively) any substantially similar federal, state or local law), the Code or the Investment Company Act of 1940, as amended.

(j)    Any shares of Common Stock delivered upon the conversion of any Note to any Person that is not, and for at least three months has not been, an Affiliate of the Company shall be issued without any Restricted Stock Legend if (x) such conversion occurs after the Scheduled Free Trade Date or (y) such Note otherwise does not, or would not be required hereunder to, bear the Restricted Securities Legend.

Section 2.07     Replacement Notes . If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that such Note has been lost, destroyed or stolen and the Holder provides evidence of the loss, theft or destruction reasonably satisfactory to the Company and the Trustee, the Company shall issue, and the Trustee shall authenticate, a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond reasonably sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss that any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note.

Upon the issuance of any new Notes under this Section 2.07 , the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

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

Section 2.08     Outstanding Notes . Notes outstanding at any time include and are limited to all Notes authenticated by the Trustee except (i) Notes cancelled by the Trustee or required to be delivered to the Trustee for cancellation in accordance with Section 2.10 , (ii) Notes, or portions thereof, the principal of which has become due and payable on the Maturity Date, on a Fundamental Change Purchase Date or otherwise, and in respect of which monies in the necessary amount shall have been deposited in trust with the Trustee or with any Paying Agent (other than the Company) or shall have been set aside and segregated in trust by the Company (if the Company shall act as its own Paying Agent), (iii) Notes, or portions thereof, that have been converted pursuant to Article X and that are required to be cancelled pursuant to Section 2.10 and (iv) Notes repurchased by the Company, directly or indirectly, whether by the Company or its Subsidiaries, pursuant to Section 2.14 (other than Notes repurchased pursuant to cash-settled swaps or other derivatives). For the purpose of determining whether the Holders of the requisite principal amount of Notes have given or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder (including, without limitation, determinations pursuant to Articles VI and IX ) only outstanding Notes shall be considered in any such determination. In addition, for the purpose of any such determination, Notes that are owned by the Company, by any Subsidiary thereof or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining

whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action only Notes that a Trust Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 2.08 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or a Subsidiary 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.

Section 2.09      Temporary Notes . Until Certificated Notes are ready for delivery, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed) ( “Temporary Notes” ). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of Certificated Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. 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 Certificated Notes. Without unreasonable delay the Company will prepare, execute and deliver to the Trustee or such authenticating agent Certificated 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 2.04 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such Temporary Notes an equal aggregate principal amount of Certificated 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 this Indenture as Certificated Notes authenticated and delivered hereunder.

Section 2.10      Cancellation . The Company shall cause all Notes surrendered for the purpose of payment, repurchase (including pursuant to Section 3.01 or Section 2.14 , other than Notes repurchased pursuant to cash-settled swaps or other derivatives), 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 canceled promptly by it, and no Notes shall be authenticated in exchange therefor except as expressly permitted by any of the provisions of this Indenture. The Trustee shall cancel Notes in accordance with its customary procedures and, after such cancellation, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order.

Section 2.11      Persons Deemed Owners . Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving payment of principal, interest, if any, or payment of the Fundamental Change Purchase Price, for the purpose of conversion and for all other purposes whatsoever, subject to Section 2.06(i) , Section 2.08 and Section 2.12(a)(ii) , whether or not such Note be overdue, and

neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12     Transfer of Notes .

(a)    Notwithstanding any other provisions of this Indenture or the Notes, (A) any transfer of a Global Note, in whole or in part, shall be made only in accordance with Sections 2.06 and 2.12(a)(i) ; and (B) any exchange of a beneficial interest in a Global Note for a Certificated Note shall comply with Sections 2.06 and 2.12(a)(ii) . All such transfers and exchanges shall comply with the Applicable Procedures to the extent so required.

(i)     Transfer of Global Note . A Global Note may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no transfer of a Global Note to any other Person may be registered; provided that this clause (i) shall not prohibit any transfer of a Note that is issued in exchange for a Global Note but is not itself a Global Note. 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. Nothing in this Section 2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Note effected in accordance with the other provisions of this Section 2.12(a) .

(ii)     Restrictions on Exchange of a Beneficial Interest in a Global Note for a Certificated Note . Unless the Company and the applicable Holder otherwise agree, a Certificated Note will be issued and delivered:

(A)    to each Person that DTC identifies as a beneficial owner of the related Notes only if (a) DTC notifies the Company that it is unwilling or unable to continue as Depositary for the Global Notes and a successor Depositary is not appointed by the Company within 90 days of such notice; or (b) DTC ceases to be registered as a clearing agency under the Exchange Act and a successor Depositary is not appointed by the Company within 90 days of such cessation; or

(B)    if an Event of Default has occurred and is continuing, to each beneficial owner who requests that its beneficial interests in the Notes be exchanged for Certificated Notes.

In connection with the exchange of an entire Global Note for Certificated Notes pursuant to this Section 2.12(a)(ii) , such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon Company Order the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Certificated Notes of authorized denominations.

(b)    Upon receipt by the Registrar of instructions from the Holder of a Global Note pursuant to Section 2.12(a) above directing the Registrar to (x) issue one or more Certificated Notes in the amounts specified to the owner of a beneficial interest in such Global Note and (y) debit or cause to be debited an equivalent amount of beneficial interest in such Global Note, subject to the Applicable Procedures:

(i)      the Registrar shall notify the Company and the Trustee of such instructions and identify the owner of and the amount of such beneficial interest in such Global Note;

(ii)      the Company shall promptly execute, and upon Company Order, the Trustee shall authenticate and deliver, to such beneficial owner Certificated Note(s) in an equivalent amount to such beneficial interest in such Global Note; and

(iii)      the Registrar shall decrease such Global Note by such amount in accordance with the foregoing.

(c)      Restrictions on Transfer of a Certificated Note for a Beneficial Interest in a Global Note. A Certificated Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below.

(i)      Upon receipt by the Trustee of a Certificated Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with written instructions directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Note and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of Notes represented by the Global Note to be increased by the aggregate principal amount of the Certificated Note to be exchanged, and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the principal amount of the Certificated Note so cancelled. If no Global Notes are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officer’s Certificate, a new Global Note in the appropriate principal amount.

(ii)      None of the Trustee, the Paying Agent, the Registrar or the Conversion Agent shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among DTC participants, members or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(iii)      None of the Trustee, the Paying Agent, the Registrar or the Conversion Agent shall have any responsibility or obligation to any beneficial owner in a Global Note, a DTC participant or other Person with respect to the accuracy of the records of DTC or its nominee or of any DTC participant, with respect to any ownership interest in the Notes or with respect to the delivery to any DTC participant, beneficial owner or other Person (other than DTC) of any notice or the payment of any amount, under or with respect to such Notes. All notices

and communications to be given to the Holders and all payments to be made to Holders under the Notes and this Indenture shall be given or made only to or upon the order of the registered Holders (which shall be DTC or its nominee in the case of the Global Note). The rights of beneficial owners in the Global Note shall be exercised only through DTC subject to the Applicable Procedures. The Trustee, the Paying Agent, the Registrar and the Conversion Agent shall be entitled to rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners. The Trustee, the Paying Agent, the Registrar and the Conversion Agent shall be entitled to deal with DTC, and any nominee thereof, that is the registered Holder of any Global Note for all purposes of this Indenture relating to such Global Note (including the payment of principal and interest and the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Note) as the sole holder of such Global Note and shall have no obligations to the beneficial owners thereof. None of the Trustee, the Paying Agent, the Registrar or the Conversion Agent shall have any responsibility or liability for any acts or omissions of DTC with respect to such Global Note, for the records of any such Depositary, including records in respect of beneficial ownership interests in respect of any such Global Note, for any transactions between the DTC and any DTC participant or between or among DTC, any such DTC participant and/or any holder or owner of a beneficial interest in such Global Note, or for any transfers of beneficial interests in any such Global Note.

(iv)      Notwithstanding the foregoing, with respect to any Global Note, 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 DTC (or its nominee), as a Holder, with respect to such Global Note or shall impair, as between DTC and owners of beneficial interests in such Global Note, the operation of customary practices governing the exercise of the rights of DTC (or its nominee) as Holder of such Global Note.

Section 2.13      CUSIP and ISIN Numbers .

(a)      The Company, in issuing the Notes, shall use restricted CUSIP, ISIN or other similar numbers for such Notes (if then generally in use) until such time as the Restricted Securities Legend is removed therefrom. At such time as the legend is removed from such Notes, the Company will use an unrestricted CUSIP number for such Note, but only with respect to the Notes where so removed. The Company and the Trustee may use CUSIP, ISIN or other similar numbers in notices as a convenience to Holders; provided , however , that neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP, ISIN or other similar number that appears on any Note, check, advice of payment or notice, and 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 and that reliance may be placed only on the other identification numbers printed on the Notes, and any action taken in connection with such a notice shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in the event of any change in the CUSIP, ISIN or other similar numbers.

(b)      Until such time as the Restricted Stock Legend is no longer required to be borne by any shares of Common Stock issued upon the conversion of the Notes pursuant to Section 2.06(f) or otherwise, any shares of Common Stock issued upon conversion of the Notes shall bear a restricted CUSIP number. At such time as the Restrictive Stock Legend is no longer required to be borne by any shares of Common Stock issued upon the conversion of the Notes pursuant to Section 2.06(f) or otherwise, any shares of Common Stock issued upon conversion of the Notes shall bear an unrestricted CUSIP number.

Section 2.14      Additional Notes; Repurchases . The Company may, without the consent of the Holders and notwithstanding Section 2.01 , reopen this Indenture and issue additional Notes with the same terms as the Notes initially issued hereunder (other than as to interest accrual dates and transfer restrictions) in an unlimited aggregate principal amount, provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order and an Officer’s Certificate, which shall cover such matters, in addition to those required by Section 14.03 , as the Trustee shall reasonably request. In addition, upon the reasonable request of the Trustee, the Company shall furnish to the Trustee an Opinion of Counsel which shall cover the matters required by Section 14.03 . 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, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash settled swaps or other derivatives.

(b)      Upon the Paying Agent’s receipt of (x) a valid Fundamental Change Purchase Notice (together with all necessary endorsements) and (y) the Notes to which such Fundamental Change Purchase Notice pertains, the Holder of the Notes to which such Fundamental Change Purchase Notice pertains shall be entitled, except to the extent such Holder has validly withdrawn such Fundamental Change Purchase Notice in accordance with Section 3.03(c) above, to receive the Fundamental Change Purchase Price with respect to such Notes promptly on the later of (i) the Fundamental Change Purchase Date and (ii) if the Notes are Certificated Notes, the date of delivery of such Notes to the Paying Agent, or, if the Notes are Global Notes, the date of book-entry transfer.

Section 3.09      Covenant Not to Purchase Notes Upon Certain Events of Default .

(a)      Notwithstanding anything to the contrary in this Article III , the Company shall not purchase any Notes under this Article III if there has occurred and is continuing an Event of Default with respect to the Notes, unless the payment by the Company of the Fundamental Change Purchase Price will cure such Event of Default.

(b)      If a Fundamental Change Purchase Notice is tendered and, on the Fundamental Change Purchase Date, such Fundamental Change Purchase Notice has not been validly withdrawn in accordance with Section 3.03(c) above, and, pursuant to this Section 3.09 , the Company is not

permitted to purchase Notes, the Paying Agent will deem withdrawn such Fundamental Change Purchase Notice.

Any such document or report that the Company

files with the SEC via the SEC’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 4.02(a) at the time such documents are filed via the EDGAR system.

(b)      If, at any time during the period beginning on, and including, the date which is six months after the Original Issuance Date until the Scheduled Free Trade Date, the Company fails to timely file any report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (other than reports on Form 8-K), or the Notes are not otherwise freely tradeable by Holders other than the Company’s Affiliates (as a result of restrictions pursuant to U.S. securities laws), the Company shall pay Additional Interest on the Notes, which shall accrue at a rate of 0.50% per annum , from and including the later of the date six months after the Original Issuance Date and the first date on which such failure to file exists or the Notes are not freely tradeable, as the case may be, until the earlier of (i) the Scheduled Free Trade Date and (ii) the date on which such failure to file has been cured (if applicable) and the Notes are freely tradeable.

(c)      The Company will use its reasonable best efforts to remove the Restrictive Securities Legend on the Notes and have an unrestricted CUSIP number assigned to the Notes (other than the Notes held by Affiliates of the Company) as of the Scheduled Free Trade Date.

(d)      Any Additional Interest payable in accordance with this Section 4.02 , together with any Additional Interest payable as a result of the Company’s election pursuant to Section 6.01 , shall not in the aggregate exceed a combined rate of 0.50% per annum .

Such Officer’s Certificate 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. Unless and until the Trustee receives such an Officer’s Certificate, subject to Section 6.01(c) , the Trustee may assume without inquiry that no such Additional Interest is payable.

(j)      Delivery of any such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

Section 4.03      Compliance Certificate . Within 120 days after the end of each fiscal year (beginning with the fiscal year ending December 31, 2014) of the Company, the Company shall deliver to the Trustee at its Corporate Trust Office in accordance with Section 14.01 , making specific

reference to this Indenture, the Notes and the Company, an Officer’s Certificate indicating whether each signer thereof knows of any Default that occurred during the previous year and, if so, shall specify each such Default and the nature and status thereof of which it may have knowledge and what action the Company is taking or proposes to take in respect thereof.

Section 4.04      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 this Indenture.

Section 4.05      Provisions as to Paying Agent .

(i)      that it will hold all sums held by it as such agent for the payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes;

(ii)      that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and

(iii)      that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Company shall, on or before each due date of the principal (including the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Purchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date.

(b)      If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change Purchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable.

(c)      Anything in this Section 4.05 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any

other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.05 , such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

Subject to applicable abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Purchase Price, if applicable) or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however , that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, New York City, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 calendar days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 4.06      Delivery of Certain Information . If, at any time, the Company is not subject to the reporting requirements of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof will, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, upon the request of any Holder, beneficial owner or prospective purchaser of the Notes or any shares of Common Stock issuable upon the conversion of Notes, promptly furnish to such Holder, beneficial owner or prospective purchaser the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of the Notes or such shares of Common Stock pursuant to Rule 144A, as such rule may be amended from time to time.

Section 5.01      Company May Consolidate, Merge or Sell Its Assets on Certain Terms . The Company shall not consolidate with, merge with or into or enter into, or convey, transfer or lease all or substantially all of the property and assets of the Company and its Subsidiaries, taken as a whole, to any Person, unless:

(a)      the resulting, surviving or transferee Person (the “Successor Company” ) is a corporation organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia, and such Successor Company (if other than the Company)

expressly assumes, by a supplemental indenture executed and delivered to the Trustee, all of the Company’s obligations under the Notes and under this Indenture;

(b)      immediately after giving effect to such transaction, no Default or Event of Default has occurred or is continuing; and

(c)      the Company or the Successor Company (if other than the Company) shall have delivered to the Trustee an Officer’s Certificate stating that:

(i)      each of (x) such consolidation, merger, conveyance, transfer or lease and (y) such supplemental indenture complies with this Article V ; and

(ii)      all conditions precedent relating to such transaction provided herein have been complied with.

For purposes of this Section 5.01 , any conveyance, transfer or lease of properties and assets of one or more Subsidiaries of the Company that would, if the Company had held such properties and assets directly, have constituted the conveyance, transfer or lease of substantially all of the Company’s properties and assets shall be treated as such hereunder.

Section 5.02      Successor Corporation to be Substituted . Upon any such consolidation, merger (or similar transaction), conveyance or transfer (but not upon a lease) and the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of, accrued and unpaid interest, if any, on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue in its own name, any or all of the Notes issuable hereunder which 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 this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, 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 this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. Upon any such consolidation, merger (or similar transaction), conveyance or transfer (but not upon a lease), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article V may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture.

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

(c)      Notwithstanding anything to the contrary in the Notes or elsewhere in this Indenture, except as provided in Section 4.02(b) , at the election of the Company, the sole remedy of Holders for an Event of Default relating to the failure by the Company to comply with its obligation to file reports, information or documents with the Trustee pursuant to Section 4.02(a) (the “Company’s Filing Obligations” ) shall, (i) for the first 90 days after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest at a rate equal to 0.25% per annum on the principal amount of the Notes then outstanding, and (ii) for the 90 days immediately following such initial 90-day period, consist exclusively of the right to receive Additional Interest at a rate equal to 0.50% per annum on the principal amount of the Notes then outstanding. Such Additional Interest shall not, together with any Additional Interest that the Company is required to pay under Section 4.02(b) , exceed 0.50% per annum . If the Company makes such election to pay Additional Interest, such Additional Interest shall be payable in arrears on each Interest Payment Date following

the date on which such Event of Default first occurred in the same manner as stated interest payable on the Notes. On the 181 ^st day following the date on which such Event of Default first occurred (if the failure to comply with the Company’s Filing Obligations is not cured or waived prior to such 181 ^st day), the Notes shall be subject to acceleration as provided in Section 6.02 . The provisions contained in this Section 6.01(c) shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. If the Company does not elect to pay Additional Interest upon an Event of Default in accordance with this Section 6.01(c) , the Notes shall be subject to acceleration as provided in Section 6.02 . In order to elect to pay Additional Interest as the sole remedy for the first 180 days after the occurrence of an Event of Default relating to the failure by the Company to comply with the Company’s Filing Obligations, the Company must notify, in the manner provided for in Section 14.01 , the Paying Agent, the Trustee and all Holders of the Notes of such election at any time on or before the date on which such Event of Default otherwise would occur (which notice shall include a statement as to the date from which Additional Interest is payable and, in the case of the Trustee, shall be delivered to its Corporate Trust Office and shall make explicit reference to this Indenture, the Notes and the Company). Unless and until a Trust Officer receives at the Corporate Trust Office such notice, the Trustee may assume without inquiry that no Additional Interest is payable. Upon failure by the Company to timely give such notice to pay such Additional Interest, or if the Company has provided such notice but has failed to pay such Additional Interest, the Notes shall be immediately subject to acceleration as provided in Section 6.02 . If Additional Interest has been paid by the Company directly to the Persons entitled to it, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment.

Section 6.02     Acceleration . If an Event of Default (other than an Event of Default specified in Section 6.01(a)(ix) or Section 6.01(a)(x) with respect to the Company) occurs and is continuing, and in each and every such case, except for any Notes the principal of which shall have already become due and payable, either the Trustee, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may declare 100% of the principal amount of, and accrued and unpaid interest on, all of the Notes then outstanding, to be due and payable immediately, and upon such a declaration, the same shall be immediately due and payable. If an Event of Default specified in Section 6.01(a)(ix) or Section 6.01(a)(x) occurs with respect to the Company, 100% of the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding shall, automatically and without any notice or other action by the Trustee or any Holder, be and become immediately due and payable, to the fullest extent permitted by applicable law. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by written notice to the Trustee and the Company, and without notice to any other Holder, may rescind any acceleration of the Notes if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the principal of and interest on the Notes that have become due solely by such acceleration, have been cured or waived. Any such rescission shall not affect any subsequent Default or impair any right consequent thereon.

Section 6.03     Other Remedies . If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of the Notes in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.04      Waiver of Past Defaults . The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by written notice to the Trustee and the Company and without notice to any other Holder, may waive any Default, except with respect to (a) any failure by the Company to pay the principal of or accrued interest on the Notes (including the Fundamental Change Purchase Price, if applicable), (b) any failure by the Company to comply with its obligations to purchase Notes when required to do so under Article III , (c) any failure by the Company to deliver any consideration due upon conversion or (d) any failure by the Company to comply with any covenant or provision of this Indenture or the Notes that under Section 9.02 cannot be modified or amended without the consent of each Holder. Any such waiver shall not affect any subsequent or other Default or impair any right consequent thereon.

Section 6.05      Control by Majority . The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may 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; provided that (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or would involve the Trustee in personal liability and (ii) for the avoidance of doubt, the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Subject to Article VII, if an Event of Default has occurred and is continuing, the Trustee shall be under no obligation to exercise any of its rights or powers hereunder at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to the Trustee against any loss, liability or expense caused by taking such action.

Section 6.06      Limitation on Suits . Except to enforce its rights to receive payment of principal or interest (including the Fundamental Change Purchase Price, if applicable) when due, to receive payment or delivery of the consideration due upon conversion and as provided in Section 6.07 , no Holder may institute any proceeding, judicial or otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(a)      such Holder shall have previously given to the Trustee written notice that an Event of Default has occurred and is continuing;

(b)      the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding shall have made a written request to the Trustee to take such action;

(c)      such Holder or Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs and other liabilities of compliance with such written request;

(d)      the Trustee shall not have complied with such written request during the first 60 days after receiving such notice, request and offer of security or indemnity; and

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

A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder.

Section 6.07      Rights of Holders to Receive Payment; Suit Therefor .

Section 6.09      Trustee May File Proofs of Claim . The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, if the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.06 .

TRUSTEE

Section 7.01      Duties of Trustee .

(a)      If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use in the conduct of such person’s own affairs.

(b)      Except during the continuance of an Event of Default:

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

(ii)      in the absence of bad faith or negligence on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however , that the Trustee will examine the certificates and opinions to determine whether they conform to the requirements set forth

in this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts, statements, opinions or conclusions stated therein).

(c)      The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(i)      this sub-section  (c) does not limit the effect of the remainder of this Section 7.01 ;

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

(iii)      the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof, or exercising any trust or power conferred upon the Trustee under this Indenture absent negligence or willful misconduct.

(d)      All monies received by the Trustee shall, until delivered to the applicable Holders as herein provided, be held in trust in a non-interest bearing account for the purposes for which they were received. Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law.

(e)      No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers. The Trustee shall not be required to give any bond or surety in respect of the performance of its powers or duties hereunder.

Section 7.02      Rights of Trustee .

(a)      The Trustee may conclusively rely upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in any such resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document. The Trustee may, however, in its discretion make such further inquiry or investigation into such

facts or matters as it may see fit and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole expense of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(b)      Before the Trustee acts or refrains from acting (except in connection with an application for authorization of Notes pursuant to Section 2.03 ) at the direction of the Company, it may require an Officer’s Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officer’s Certificate or Opinion of Counsel and may conclusively rely upon such Officer’s Certificate or Opinion of Counsel.

(c)      The Trustee may act through agents, attorneys or custodians and shall not be responsible for the misconduct or negligence of any agent, attorney or custodian appointed with due care hereunder.

(d)      The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture; provided, however , that the Trustee’s conduct does not constitute willful misconduct or negligence.

(e)      The Trustee may consult with counsel of its own selection, and the written advice or opinion of counsel with respect to legal matters relating to this Indenture and the Notes shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f)      The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified herein.

(g)      The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee in accordance with such Section.

(h)      The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person

employed to act hereunder, including, without limitation, the Registrar, Paying Agents and Conversion Agent.

(i)      The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which certificate may be signed by any Person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded.

(j)      Anything in this Indenture notwithstanding, in no event shall the Trustee be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Trustee has been advised as to the likelihood of such loss or damage and regardless of the form of action.

(k)      Any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Order or any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution.

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

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

Section 7.05      Notice of Defaults . If a Default or Event of Default occurs and is continuing and is known to a Trust Officer, the Trustee shall mail to each Holder written notice of such Default or Event of Default within 90 days after it occurs, or if later, a Trustee Officer has knowledge of such Default or Event of Default; provided that except in the case of a Default described in Section 6.01(a)(i) , Section 6.01(a)(ii) or Section 6.01(a)(iii) , the Trustee may withhold the notice (except in payment on the Notes or the failure to convert the Notes in accordance with this Indenture) if and so long as a committee of Trust Officers of the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

Section 7.06      Compensation and Indemnity .

(a)      The Company shall pay to the Trustee from time to time such compensation as shall be agreed upon from time to time in writing for all services rendered by it hereunder in any capacity. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket fees and expenses incurred or made by it, including costs of collection, in addition to the

compensation for its services. Such expenses shall include the reasonable compensation, fees and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts and of all Persons not regularly in its employ. The Company shall fully indemnify the Trustee in any capacity under this Indenture and any other document or transaction entered into in connection herewith against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) incurred by it in connection with the acceptance and administration of this trust and the performance of its duties hereunder in any capacity, including the costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person). The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence. All indemnifications and releases from liability granted hereunder to the Trustee shall extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns.

(b)      To secure the Company’s payment obligations under this Section 7.06 , the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay the principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price on particular Notes.

(c)      The Company’s payment obligations pursuant to this Section 7.06 shall survive the resignation or removal of the Trustee and the discharge of this Indenture. If the Trustee incurs expenses (including the reasonable charges and expenses of its counsel) after the occurrence of a Default specified in Section 6.01(a)(ix) or Section 6.01(a)(x) with respect to the Company, the expenses are intended to constitute expenses of administration under applicable bankruptcy laws.

(e)      The provisions of this Section shall survive the satisfaction and discharge of the Indenture, the termination for any reason of this Indenture, and the resignation or removal of the Trustee.

Section 7.07      Replacement of Trustee .

(a)      The Trustee may resign at any time by notifying the Company in writing and by mailing notice thereof to the Holders at their addresses as they shall appear on the Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor Trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor Trustee. If no successor Trustee shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor Trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor Trustee.

(b)      In case at any time any of the following shall occur:

(iii)      the Trustee shall cease to be eligible in accordance with the provisions of Section 7.10 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(iv)      the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor Trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor Trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor Trustee.

(c)      The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and nominate a successor Trustee that shall be deemed appointed as successor Trustee, unless within ten days after notice to the Company of such nomination the Company objects thereto, in which case the Trustee so removed or any Holder, upon the terms and conditions and otherwise as specified in clause (a) above, may petition any court of competent jurisdiction for an appointment of a successor Trustee.

(d)      Any resignation or removal of the Trustee and appointment of a successor Trustee pursuant to any of the provisions of this Section 7.07 shall become effective upon acceptance of appointment by the successor Trustee as provided in Section 7.08 .

Section 7.08      Acceptance by Successor Trustee . Any successor Trustee appointed as provided in Section 7.07 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor Trustee, the Trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06 , execute and deliver an instrument transferring to such successor Trustee all the rights and powers of the Trustee so ceasing to act. Upon request of any such successor Trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a lien prior to the Notes on all money or property held or collected by the Trustee, other than money or property held in trust to pay the principal, accrued and unpaid interest, if any, or payment

of the Fundamental Change Purchase Price on particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06 .

No successor Trustee shall accept appointment as provided in this Section 7.08 unless at the time of such acceptance such successor Trustee shall be eligible under the provisions of Section 7.10 .

Upon acceptance of appointment by a successor Trustee as provided in this Section 7.08 , each of the Company and the successor Trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such Trustee hereunder to the Holders at their addresses as they shall appear on the Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the Company.

Section 7.09      Successor Trustee by Merger .

(a)      If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets (including administration of this Indenture) to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee; provided that if such successor Trustee is not eligible to act as Trustee pursuant to Section 7.10 , such successor Trustee shall promptly resign pursuant to Section 7.07 .

(b)      In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any such successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee.

Section 7.10      Eligibility; Disqualification . The Trustee must be a Person who is eligible to act as an indenture trustee under the TIA and must have a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Article.

(b)      (i) Prior to the Close of Business on the Business Day immediately preceding December 15, 2020, a Holder may surrender all of a portion of its Notes for conversion during any fiscal quarter (and only during such fiscal quarter) commencing after March 31, 2014, if, for at least 20 Trading Days (whether or not consecutive) during the 30 consecutive Trading Day period ending on the last Trading Day of the immediately preceding fiscal quarter, the Last Reported Sale Price of the Common Stock on such Trading Day is greater than or equal to 130% of the applicable Conversion Price on such Trading Day (such condition, the “Sale Price Condition” ). If the Sale Price Condition has been met, the Company shall notify Holders in writing of its satisfaction and of the resulting right of Holders to convert their Notes within one Business Day of the Sale Price Condition being met.

(ii)      Prior to the Close of Business on the Business Day immediately preceding December 15, 2020, a Holder may surrender all of a portion of its Notes for conversion

If, on any Trading Day after the Trading Price Condition has been met, the Company determines that the Trading Price per $1,000 principal amount of Notes for such Trading Day is greater than or equal to 98% of the Intrinsic Value of the Notes for such Trading Day, the Company shall promptly so notify the Holders that the Trading Price Condition is no longer met.

(iii)      If, prior to the Close of Business on December 15, 2020, the Company elects to:

(A)      issue to all or substantially all holders of its Common Stock any rights, options or warrants (other than pursuant to a stockholder rights plan) entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock, at a price per share of Common Stock less than the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and

including, the Trading Day immediately preceding the date of announcement of such issuance; or

(B)      distribute to all or substantially all holders of the 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 immediately preceding the date of announcement for such distribution,

then, in each case, at least 30 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution, the Company shall mail written notice to the Holders describing such issuance or distribution, the Holders’ rights to convert their Notes in accordance with this Section 10.01(b)(iii) , the Conversion Rate in effect on the date the Company mails such notice, any adjustments to the Conversion Rate that must be made as a result of such issuance or distribution, and the effective date for any such adjustments. Once the Company has given such notice, a Holder may surrender all or a portion of its Notes for conversion at any time until the earlier of (x) the Close of Business on the Business Day immediately preceding such Ex-Dividend Date and (y) the Company’s announcement that such issuance or distribution will not take place (even if the Notes are not otherwise convertible at such time). Notwithstanding this Section 10.01(b)(iii) , Holders of the Notes will not be permitted to so surrender the Notes for conversion if such Holders are entitled to participate (solely as a result of holding the Notes), at the same time and on the same terms as holders of the Common Stock, in such issuance or distribution without having to convert the Notes as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(iii)      If, prior to the Close of Business on December 15, 2020, a Fundamental Change, a Make-Whole Fundamental Change or Share Exchange Event occurs, regardless of whether the Holders would have the right to require the Company to purchase their Notes pursuant to Article III , (any such event, a “ Specified Corporate Transaction ”), the Company shall mail written notice (a “Specified Corporate Transaction Notice” ) of such Specified Corporate Transaction to the Holders within five Business Day of the occurrence of such transaction or event. The Specified Corporate Transaction Notice shall describe:

(A)      the transaction or event;

(B)      the effective date of such transaction or event;

(C)      the Holders’ right to convert their Notes in accordance with this Section 10.01(b)(iv) ;

(D)      the Conversion Rate in effect on the date the Company mails such Specified Corporate Transaction Notice;

(E)      whether an adjustment to the Conversion Rate is expected to be made pursuant to Section 10.05 as a result of such transaction or event and the formula for determining such adjustment;

(F)      whether the relevant transaction or event constitutes a Share Exchange Event, and, if so, that the Notes will become convertible into Reference Property, subject to the settlement provisions of the Indenture;

(G)      whether the relevant transaction or event constitutes a Fundamental Change, and, if so, that Holders will have the right to require the Company to purchase their Notes pursuant to Article III ; and

(H)      whether the relevant transaction or event constitutes a Make-Whole Fundamental Change, and, if so, that the Conversion Rate will be increased under Section 10.07 for Notes converted in connection with such Make-Whole Fundamental Change.

Upon the Company’s delivery of a Specified Corporate Transaction Notice, a Holder may surrender all or a portion of its Notes for conversion at any time until the 35th Trading Day immediately following the effective date of such transaction, or, if such transaction constitutes a Fundamental Change, the Business Day immediately preceding the related Fundamental Change Purchase Date.

Section 10.02      Conversion Procedure .

(a)      To convert a Note or portion thereof, a Holder or beneficial owner, as the case may be, must (i) in the case of a Global Note, (a) comply with the procedures of the Depositary then in effect for converting a beneficial interest in a Global Note and (b) if required, pay all funds required under Section 10.02(g) and Section 10.02(h) below, and (ii) in the case of a Certificated Note, (a) complete and manually sign the conversion notice in the form attached to such Certificated Note (a “Notice of Conversion” ) or a facsimile of the Notice of Conversion, (b) deliver the Notice of Conversion, which is irrevocable, and the Certificated Note to the Conversion Agent, (c) if required, furnish appropriate endorsements and transfer documents, (d) if required, pay all funds required under Section 10.02(h) below, and (e) if required, pay all funds required under Section 10.02(g) below.

(b)      A Note shall be deemed to have been converted at the Close of Business on the first Business Day (the “Conversion Date” ) on which (i) the Holder thereof satisfies all of the requirements set forth in Section 10.02(a) with respect to such Note and (ii) the conversion of such Note is not otherwise prohibited by Section 3.04(a) hereof.

(c)      Upon the conversion of a Note, the Conversion Agent, as promptly as possible, and in no event later than one Business Day immediately following the Conversion Date for the Note, will provide the Company with notice of the conversion of the Note, and the Company, as promptly as possible, and in no event later than two Business Days after such Conversion Date, will notify the Trustee, if other than the Conversion Agent, of the conversion of the Note.

(d)      If a Holder converts the entire principal amount of a Note, such Person will no longer be a Holder of such Note, except that such Holder shall have the right hereunder to receive the consideration due upon conversion and as provided in Section 10.02(g) .

(e)      If a Holder surrenders only a portion of a Certificated Note for conversion, promptly after the Conversion Date for such portion, the Company shall execute and the Trustee shall authenticate and deliver to such Holder, a new Certificated Note in an authorized denomination equal to the aggregate principal amount of the unconverted portion of the surrendered Note. Upon the conversion of an interest in a Global Note, the Trustee shall promptly make a notation on the “Schedule of Exchanges of Notes” of such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing upon any conversion of a Note effected through any Conversion Agent other than the Trustee.

(f)      If any shares of Common Stock are to be delivered upon the conversion of a Note, the converting Holder (or its designee) shall be treated as the holder of record of such shares as of the last VWAP Trading Day of the relevant Observation Period for such Note.

(g)      Notwithstanding Section 10.03(f) , if a Holder converts its Note after the Close of Business on a Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Record Date, the Holder of such Note at the Close of Business on such Record Date shall receive the interest payment payable on such Note on such corresponding Interest Payment Date, notwithstanding the conversion. Any Note converted during the period beginning at the Close of Business on any Record Date and ending at the Open of Business on the Interest Payment Date corresponding to such Record Date must be accompanied by funds equal to the amount of interest payable on such Note on such corresponding Interest Payment Date; provided, however, that no such payment need be made: (i) for a Note surrendered for conversion after the Close of Business on the Record Date immediately preceding the Maturity Date, (ii) if the Company has specified a Fundamental Change Purchase Date that is after such Record Date and on or prior to such corresponding Interest Payment Date, or (iii) to the extent of any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect to such Note. For the avoidance of doubt, the Company shall pay interest on the Maturity Date on all Notes converted after the Record Date immediately preceding the Maturity Date, and converting Holders shall not be required to pay to the Company equivalent interest amounts.

(h)      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 such conversion; provided that if such tax is due because such converting Holder requested that such shares of Common Stock be issued in a name other than such Holder’s name, such Holder shall pay such tax.

Section 10.03      Settlement Upon Conversion .

(a)      Except as provided in Section 10.07(e) , upon conversion of any Note, the Company shall deliver to a converting Holder, in respect of each $1,000 principal amount of Notes being converted, an amount of cash and a number of shares of Common Stock, if any, equal to the sum of the Daily Settlement Amounts for each VWAP Trading Day in the Observation Period for such

Note (the “ Settlement Amount ”), together with cash in lieu of any fractional shares. The Company shall deliver the Settlement Amount due in respect of the Conversion Obligation for any such Note to the converting Holder on the third Business Day immediately following the last VWAP Trading Day of the Observation Period.

(b)     

(i)      Except as provided in Section 10.07(e) , upon conversion of any Note, the Company shall satisfy the Daily Net Settlement Amount included in any Daily Settlement Amount by delivering cash, shares of Common Stock or a combination thereof, at the Company’s election, (each of these settlement methods a “ Settlement Method ”). For purposes of this provision, the Company’s obligation in respect of the Daily Net Settlement Amounts is referred to as the “ Conversion Excess Obligation .”

(ii)      If the Company elects to satisfy all or any portion of the Conversion Excess Obligation in cash (the “ Cash Settlement Election ”), the Company will notify holders of the percentage of the Conversion Excess Obligation to be paid in cash (the “ Cash Percentage ”).

(iii)      Any Cash Settlement Election shall be the same for all conversions occurring on or after the 30th Scheduled Trading Day immediately preceding the Maturity Date. Otherwise, the Company will not have any obligation to settle conversions occurring on different Conversion Dates using a particular Settlement Method Notice, and the Company may make a Cash Settlement Election with respect to certain Conversion Dates and not with respect to other Conversion Dates.

(vi)      If the Company elects the Cash Settlement Election, the Company shall deliver a notice, which shall specify the Cash Percentage, (the “Settlement Method Notice” ) in respect of any Conversion Date or any of the periods described below, as the case may be:

(A)      by written notice to all Holders of Notes, the Trustee and the Conversion Agent on or prior to the 30th Scheduled Trading Day immediately preceding the Maturity Date, in the case of any conversion occurring on or after such date; or

(B)      by written notice to the converting Holder, the Trustee and the Conversion Agent, prior to the Close of Business on the second Scheduled Trading Day following the relevant Conversion Date, in the case of any other conversion.

(v)      If the Company does not timely deliver a Settlement Method Notice prior to the deadline set forth in Section 10.03(b)(iv) , a Cash Settlement Election will not apply with respect to such conversion, and the Company will settle the Company’s Conversion Excess Obligation by delivering shares of Common Stock with respect to the Daily Net Settlement Amounts.

(vi)      The Daily Settlement Amounts and the Daily Conversion Values shall be determined by the Company promptly following the last day of the Observation Period. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(vii)      The Company shall not deliver any fractional share of Common Stock upon conversion of the Notes. Instead, the Company will deliver, in lieu of such fraction of a share, an amount of cash equal to the product of such fraction of a share and the Daily VWAP on the last day of the relevant Observation Period. The Company will determine the number of fractional shares for which the Company will deliver cash by aggregating all of the Notes that a holder has surrendered for conversion on a Conversion Date.

(c)      Notwithstanding this Section 10.03 , and regardless of whether the Company then has a class of securities listed on the New York Stock Exchange, the number of shares of Common Stock included in the Daily Net Settlement Amount on any VWAP Trading Day will not exceed the NYSE Share Cap unless, prior to such VWAP Trading Day, the Company received the requisite approval from the Company’s stockholders in accordance with the New York Stock Exchange Rule 312.03 (the “ Required NYSE Stockholder Approval ”) to permit issuance upon conversion of the Notes of such shares. If the Company receives the Required NYSE Stockholder Approval on any day, the Company shall so notify Holders, the Trustee and the Conversion Agent in writing prior to the Close of Business on such day. The Company shall not pay any cash in lieu of any shares of Common Stock that would have been included in a Daily Net Settlement Amount that are not delivered as a result of the NYSE Share Cap. The Company shall not be required to seek to obtain the Required NYSE Stockholder Approval for the issuance of Common Stock upon conversion of the Notes.

(d)      The Company shall not make any distribution of cash or other property on Common Stock or take any other action that would result in an adjustment to the Conversion Rate under Section 10.05(b) , Section 10.05(c) , Section 10.05(d) or Section 10.05(e) if, following such adjustment, the Conversion Rate would be greater than 44.3169 shares per $1,000 principal amount of Notes (as adjusted in connection with stock splits, reverse stock splits and stock dividends, as described in Section 10.05(a) ), unless the Company has received the Required NYSE Stockholder Approval.

(e)      If a Holder surrenders more than one Note for conversion on a single Conversion Date, the Settlement Amount the Company will deliver pursuant to Section 10.03(a) or Section 10.03(b)(vii) shall be determined based on the total principal amount of Notes so surrendered by such Holder.

(f)      If a Holder converts a Note, except as set forth in Section 10.02(g) , (i) such Holder shall not receive any separate cash payment (in addition to the Conversion Obligation) for accrued and unpaid interest on such Note and (ii) the Company’s delivery to such converting Holder of the Conversion Obligation shall be deemed to satisfy in full the Company’s obligation to pay to such Holder (A) the principal amount of such converted Note and (B) accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date. As a result, subject to Section 10.02(g) , accrued and unpaid interest, if any, on a converted Note to, but excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion

of Notes, subject to Section 10.02(g) , accrued and unpaid interest, if any, shall be deemed to be paid first out of the cash paid upon such conversion, if any.

(g)      Notices .

(i)      On the first Business Day immediately following the last VWAP Trading Day of the Observation Period for each Conversion Date, the Company shall deliver written notice to the Trustee stating (1) the aggregate principal amount of Notes that were converted on such Conversion Date, (2) the aggregate amount of cash and the aggregate number of shares of Common Stock that the Company is obligated to deliver to settle all of the Notes converted on such Conversion Date, and (3) the Daily Conversion Values or Daily Net Settlement Amounts, as the case may be, for each VWAP Trading Day of the Observation Period for such Conversion Date.

Section 10.04      Covenants Relating to Underlying Shares .

(a)      The Company shall, until all Notes cease to be outstanding and any consideration due upon conversion has been paid or delivered, as the case may be, reserve out of its authorized but unissued shares of Common Stock that have not been reserved for other purposes a number of shares of Common Stock, in the aggregate, equal to the product of the Maximum Conversion Rate and the aggregate principal amount of Notes then outstanding (expressed in thousands of dollars), to permit the conversion of the Notes.

(b)      The Company covenants that any shares of Common Stock delivered upon conversion of the Notes shall be duly and validly issued and fully paid and nonassessable, and shall be free from preemptive rights and shall be free of any lien or adverse claim or from any taxes or charges with respect to the issue 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)      In addition, the Company will cause any such shares of Common Stock to be listed on any stock exchange on which the Common Stock is then listed and will comply with any stock exchange rules applicable to the Notes and/or the Common Stock issuable upon conversion of the Notes.

Section 10.05      Adjustments to the Conversion Rate . The Conversion Rate shall be adjusted from time to time by the Company as described in this Section 10.05 , except that the Company shall not make any adjustments to the Conversion Rate for any Holder that participates (as a result of holding the Notes, and at the same time as the holders of the Common Stock participate) in any of the transactions described below as if such Holder held, for each $1,000 principal amount of Notes held, a number of shares of the Common Stock equal to the applicable Conversion Rate, without having to convert its Notes.

(a)      Dividends, Distributions, Splits and Combinations. If the Ex-Dividend Date occurs for any issuance by the Company of solely shares of the Common Stock as a dividend or distribution on all or substantially all of the shares of the Common Stock, or if the Company effects a share split or a share combination of the Common Stock, the Conversion Rate shall be adjusted based on the following formula:

where:

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 the case may be;

the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such Effective Date, as the case may be;

the number of shares of the Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or Effective Date, as the case may be; and

the number of shares of the Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as the case may be.

Any adjustment made under this Section 10.05(a) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution or the effective date for such share split or combination, as the case may be. If any dividend or distribution of the type described in this Section 10.05(a) is declared but not so paid or made, then the Conversion Rate shall immediately be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution to the Conversion Rate that would then be in effect had such dividend or distribution not been declared or announced. The “ Effective Date ” shall be, with respect to a share split or combination, the first date on which the shares of the Common Stock trade in the applicable exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable.

(b)      Adjustment for Rights Issue. If the Ex-Dividend Date occurs for any issuance by the Company to all or substantially all holders of the Common Stock of any rights, options or warrants entitling the holders of such rights, options or warrants for a period of not more than 60 calendar days after the announcement date of such issuance to subscribe for or purchase shares of the Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be adjusted based on the following formula:

where:

the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;

the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

the number of shares of the Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;

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

the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the ten 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 adjustment made under this Section 10.05(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 Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be readjusted, as of the date of such expiration, to the Conversion Rate that would then be in effect had the adjustment made upon the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate shall immediately be readjusted, as of the scheduled issuance date, to equal the Conversion Rate that would then be in effect had the relevant adjustment pursuant to this Section 10.05(b) not occurred.

For purposes of this Section 10.05(b) and Section 10.01(b)(iii)(A) , in determining whether any issued rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for each Trading Day in the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration that the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c)      Non-Cash Distributions .

(x)      If the Ex-Dividend Date occurs for a distribution by the Company of 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 (A) dividends or distributions (including subdivisions) and rights, options or warrants, in each case, which are described in Section 10.05(a) or Section 10.05(b) ; (B) dividends or distributions paid exclusively in cash, which are described in Section 10.05(e) ; (C) distributions of Reference Property in a transaction described in Section 10.06 ; and (D) Spin-Offs which are described in Section 10.05(c)(ii) (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, the “Distributed Property” ), then the Conversion Rate shall be adjusted based on the following formula:

where:

the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;

the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

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

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 as of the Open of Business on the Ex-Dividend Date for such distribution.

Notwithstanding the foregoing, if “ ” (as defined above) minus “FMV” (as defined above) is less than $1.00, in lieu of the foregoing adjustment, each Holder shall receive, for each $1,000 principal amount of Notes held, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of Distributed Property that such Holder would have received as if such Holder had owned a number of shares of the Common Stock equal to the Conversion Rate in effect on the record date for such distribution.

Any adjustment made under this Section 10.05(c)(i) 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, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate shall immediately be readjusted, as of the date the Board of Directors

determines not to make or pay such distribution or as of such expiration date, as the case may be, to be the Conversion Rate that would then be in effect had such distribution not been declared or to the extent such rights or warrants are not exercised, as applicable.

(ii)      With respect to an adjustment pursuant to this Section 10.05(c) , if the relevant dividend or other distribution consists 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 listed for trading or quoted (or will be listed or quoted upon consummation of the spin-off) on a U.S. national securities exchange (a “ Spin-Off ”), the Conversion Rate shall be increased based on the following formula:

where:

the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for the Spin-Off;

the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off;

the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first ten consecutive Trading Day period immediately following, but excluding, the effective date for the Spin-Off (such period, the “Valuation Period” ); and

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

Notwithstanding the foregoing, (A) if the last VWAP Trading Day of the Observation Period for any conversion occurs on or after the effective date for the Spin-Off, but less than ten Trading Days immediately following, and including, the effective date for the Spin-Off, references within this Section 10.05(c)(ii) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Settlement Amounts in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the effective date for the Spin-Off to, and including, the last VWAP Trading Day of such Observation Period, and (B) for purposes of determining the Conversion Rate applicable to any conversion for which the Conversion Date occurs during the ten Trading Days commencing on the effective date for any Spin-Off, references within this Section 10.05(c)(ii) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the effective date for such Spin-Off to, but excluding, the relevant Conversion Date.

Any adjustment made pursuant to this Section 10.05(c)(ii) shall become effective as of the Open of Business on the Ex-Dividend Date for the Spin-Off. If such Spin-Off is subsequently cancelled and does not become effective, the Conversion Rate shall be readjusted, as of the date of such cancellation, to be the Conversion Rate that would have been in effect if such Spin-Off had not been declared.

For purposes of this Section 10.05(c) (and subject in all respect to Section 10.05(i) ), 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” ): (A) are deemed to be transferred with such shares of the Common Stock; (B) are not exercisable; and (C) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.05(c) (and no adjustment to the Conversion Rate under this Section 10.05(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 10.05(c) . If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (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 10.05(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (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 redemption or purchase 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 10.05(a) , Section 10.05(b) and this Section 10.05(c) , if any dividend or distribution to which this Section 10.05(c) is applicable also includes one or both of:

(i)      a dividend or distribution of shares of Common Stock to which Section 10.05(a) is applicable (the “Clause A Distribution” ); or

(ii)      a dividend or distribution of rights, options or warrants to which Section 10.05(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 10.05(c) is applicable (the “Clause C Distribution” ) and any Conversion Rate adjustment required by this Section 10.05(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 10.05(a) and Section 10.05(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 10.05(a) or “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” within the meaning of Section 10.05(b) .

(d)      Adjustment for Cash Distributions. If the Ex-Dividend Date occurs for any cash dividend or distribution by the Company to all or substantially all holders of the outstanding Common Stock, other than regular quarterly cash dividends that do not exceed $0.025 per share (such threshold, the “ Initial Dividend Threshold ”), the Conversion Rate shall be adjusted based on the following formula:

where:

the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;

the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;

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

the Initial Dividend Threshold; provided , that if the dividend or distribution is not a regular quarterly dividend, the Initial Dividend Threshold will be deemed to be zero; and

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

The Initial Dividend Threshold is subject to adjustment in a manner inversely proportional to adjustments to the Conversion Rate, other than any adjustment provided for in this Section 10.05(d) .

If “ ” (as defined above) minus “ ” (as defined above) is less than $1.00, in lieu of the foregoing adjustment, each Holder shall receive, for each $1,000 principal amount of Notes held, at the same time and upon the same terms as holders of the Common Stock, the amount of cash such Holder would have received if such Holder had owned a number of shares of the Common Stock equal to the Conversion Rate in effect on the record date for such distribution.

Any adjustment made under this Section 10.05(d) 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 immediately readjusted, as of the date the Board of Directors determines not to make or pay such distribution, to be the Conversion Rate that would then be in effect had the related Ex-Dividend Date not occurred.

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

where:

the Conversion Rate in effect immediately prior to the Close of Business on the Expiration Date;

the Conversion Rate in effect immediately after the Close of Business on the Expiration Date;

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

the number of shares of Common Stock outstanding immediately prior to the time (the “ Consummation Time ”) such tender or exchange offer is consummated (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange pursuant to such tender offer or exchange offer);

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

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

The adjustment to the Conversion Rate under this Section 10.05(e) shall be given effect at the Close of Business on the Expiration Date. If the Expiration Date is less than ten Trading Days prior to, and including, the last VWAP Trading Day of the Observation Period in respect of any conversion, references within this Section 10.05(e) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Settlement Amounts in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last VWAP Trading Day of such Observation Period. For purposes of determining the Conversion Rate applicable to any conversion during the ten Trading Day period commencing on the Trading Day next succeeding the Expiration Date, references within this Section 10.05(e) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding, the relevant Conversion Date.

(f)      Holder Participation in Adjustment Events. Notwithstanding the provisions set forth in clauses  (a) through (e) above, if any adjustment to the Conversion Rate pursuant to such provisions becomes effective on any Ex-Dividend Date or Effective Date and a Holder that has converted its Notes would

(i)      receive shares of Common Stock based on an adjusted Conversion Rate, and

(ii)      be a record holder of such shares of Common Stock on the record date for the dividend, distribution or event giving rise to such adjustment,

then, in lieu of receiving shares of Common Stock at such an adjusted Conversion Rate, such Holder shall receive a number of shares of Common Stock, if any, upon conversion based on an unadjusted Conversion Rate and shall participate in the related dividend, distribution or other event giving rise to such adjustment.

(g)      Adjustments Not Yet Effective. If, in the case of any conversion of a Note, on any VWAP Trading Day during the Observation Period corresponding to the Conversion Date for such Note, shares of Common Stock are deliverable as part of the Daily Settlement Amount for such VWAP Trading Day, and

(i)      the Ex-Dividend Date for any issuance, dividend or distribution, the Effective Date for any share split or combination or the Expiration Date for any tender or exchange offer by the Company that, in each case, would require an adjustment to the Conversion

Rate pursuant to Section 10.05(a) , (b) , (c) , (d) or (e) occurs prior to the Company’s delivery of such shares of Common Stock to the converting Holder;

(ii)      the applicable Conversion Rate for such VWAP Trading Day will not reflect such adjustment; and

(iii)      the shares of Common Stock that the Company shall deliver to the converting Holder with respect to such VWAP Trading Day are not entitled to participate in the relevant event (because such shares were not held by such Holder on the related Ex-Dividend Date, Effective Date, Expiration Date or otherwise),

then the Company shall adjust the number of shares of Common Stock deliverable to such Holder as part of the Daily Settlement Amount for such VWAP Trading Day in a manner that appropriately reflects the relevant distribution, transaction or event.

(h)      Other Adjustments. Whenever any provision of this Indenture requires the Company to calculate the Daily VWAP, Daily Settlement Amounts, the Daily Net Settlement Amounts or Last Reported Sale Prices over a span of multiple days, the Company shall make appropriate adjustments to such prices to account for any adjustment to the Conversion Rate that becomes effective, or any event that would require an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or Expiration Date of the event occurs, at any time during the period over which such Last Reported Sale Prices are to be calculated.

(i)      Rights Plans. To the extent that the Company has a rights plan in effect upon conversion of any Note, each share of Common Stock issued upon such conversion (x) shall be entitled to receive the number of rights, if any, associated with one share of Common Stock under such rights plan, and (y) shall, if issued in certificated form, bear such legends, if any, as may be required under such rights plan; provided, however , that if prior to the Conversion Date for such Note, the rights have separated from the Common Stock in accordance with the provisions of the applicable rights plan, the converting Holder shall not be entitled to receive such rights upon conversion, and at the time of such separation, the Conversion Rate shall be adjusted in accordance with Section 10.05(c) as if the Company made a distribution of Distributed Property to the holders of the Common Stock; provided, further , that such adjustment shall be subject to readjustment upon the expiration, termination or redemption of such separated rights in accordance with Section 10.05(c) .

(j)      Voluntary Increases . In addition to those adjustments required by clauses  (a) , (b) , (c) , (d) and (e) of this Section 10.05 , and to the extent permitted by applicable law and any applicable stock exchange rules, from time to time, (i) the Company may increase the Conversion Rate of the Notes 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 best interest of the Company and (ii) the Company may (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of the Common Stock or rights to purchase shares of the Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or a similar event; provided , that the Company shall not take any action that would result in adjustment of the Conversion Rate, pursuant to this Section 10.05(j) , that would result in a reduction of the Conversion Price to less than the par value per share of the Common Stock.

(k)      No Other Adjustments. Except as expressly stated herein, the Conversion Rate shall not be subject to adjustment as a result of any issuance of shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities.

(l)      No Decreases in the Conversion Rate. Notwithstanding anything to the contrary in clauses  (a) through (e) above, if the application of the formulas set forth therein would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made, other than as a result of a reverse share split or share combination; provided that in the case of an increase in the Conversion Rate in connection with any Spin-Off, distribution on the Common Stock or issuance of rights, options or warrants to holders of Common Stock, such increase may be reversed, to the extent expressly set forth herein, on account of the cancellation of such Spin-Off, such distribution not being paid or made or the expiration of such rights, options or warrants.

(m)      Notice of Adjustments. Whenever the Conversion Rate is adjusted as herein provided, the Company shall as promptly as practicable 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 Trust 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 such 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 Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

Section 10.06      Effect of Reclassification, Consolidation, Merger or Sale .

(a)      In the case of:

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

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

(iii)      any sale, lease or other transfer to a third party of substantially all of the consolidated assets of the Company and its Subsidiaries; or

(iv)      any statutory share exchange,

in each case, as a result of which the Common Stock will be converted into, or exchanged for, stock, other securities or other property or assets (including cash or any combination thereof) (any such event, a “Share Exchange Event” and any such stock, other securities or other property or assets, “Reference Property,” and the amount of Reference Property that a holder of one share of the Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share Exchange Event, a “Unit of Reference Property” ), then the

Company or the successor or purchasing company, as the case may be, shall execute with the Trustee a supplemental indenture providing that, at and after the effective time of such Share Exchange Event, the Notes shall become convertible into Reference Property; provided that, at and after the effective time of such Share Exchange Event, the amount of cash (if any) and the number of Units of Reference Property (if any) that the Company shall deliver upon conversion of a Note shall be determined pursuant to Section 10.03 , except that for any VWAP Trading Day during the relevant Observation Period (A) to the extent practicable, the Daily VWAP for such VWAP Trading Day in a manner determined in good faith by the Company or the successor or purchasing company shall be calculated based on the value of a Unit of Reference Property on such VWAP Trading Day in a manner determined in good faith by the Company or the successor or purchasing company and (B) in lieu of each share of Common Stock that the Company would otherwise be obligated to deliver on such VWAP Trading Day, the Company shall deliver a Unit of Reference Property.

If a Share Exchange 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 the amount and kind of Reference Property used to calculate the Daily VWAP 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. 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 anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments provided for in this Article X as determined in good faith by the Company or the successor or purchasing company. If the Reference Property in respect of any Share Exchange Event includes shares of stock, securities or other property or assets of a Person other than the Company or, in the case of a transaction described in Article V , the Successor Company, then such supplemental indenture shall also be executed by such other Person.

(b)      If the Company executes a supplemental indenture pursuant to this Section 10.06 , as promptly as practicable, the Company shall file with the Trustee an Officer’s Certificate briefly describing such Share Exchange Event, the composition of a Unit of Reference Property for such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent to such Share Exchange Event under this Indenture have been complied with. Any failure to deliver such Officer’s Certificate shall not affect the legality or validity of such supplemental indenture. The Company shall also issue a press release containing such information and shall make such press release available on its website.

(c)      The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this Section 10.06 . None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes as set forth in Section 10.02 and Section 10.01 prior to the effective date of such Share Exchange Event.

(d)      The provisions of this Section 10.06 shall apply successively to successive Share Exchange Events.

Section 10.07      Adjustment to Conversion Rate Upon Certain Transactions .

(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, in the circumstances described in this Section 10.07 , increase the Conversion Rate for such Note by the number of additional shares of Common Stock (the “Additional Shares” ) determined under this Section 10.07 . For the purposes of this Section 10.07 , a conversion of Notes shall be deemed to be “in connection with” a Make-Whole Fundamental Change if the Conversion Date occurs during the period beginning on, and including, the date on which such Make-Whole Fundamental Change occurs or becomes effective (such date, the “Make-Whole Fundamental Change Effective Date” ) and ending on, and including, the Business Day immediately preceding the earliest of (i) the 35th Scheduled Trading Day immediately following the Make-Whole Fundamental Change Effective Date, (ii) the related Fundamental Change Purchase Date, if such Make-Whole Fundamental Change is also a Fundamental Change, and (iii) the Business Day immediately preceding the Maturity Date. If, prior to the Close of Business on December 15, 2020, a Make-Whole Fundamental Change occurs, regardless of whether Holders would have the right to require the Company to purchase their Notes as described in Article III , the Company will notify in writing the Holders within five Business Days after the occurrence of such transaction or event. Upon delivery of such written notice, a Holder may surrender all or a portion of its Notes for conversion until the 35th Trading Day immediately following the effective date of such transaction.

(b)      The number of Additional Shares by which the Conversion Rate shall be increased for a Note converted in connection with a Make-Whole Fundamental Change shall be determined by reference to the table in clause  (d) below, based on the relevant Make-Whole Fundamental Change Effective Date and the stock price paid (or deemed paid) in the Fundamental Change, as determined pursuant to clause  (e) below (such stock price, the “Stock Price” ).

(c)      The Stock Prices set forth in the column headings of the table in clause  (d) below shall be adjusted as of any date on which the Conversion Rate is adjusted pursuant to Section 10.05 . The adjusted Stock Prices shall equal the Stock Prices in effect immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment, and the denominator of which is the Conversion Rate in effect immediately after such adjustment. The number of Additional Shares set forth in the table in clause  (d) below shall be adjusted at the same time and in the same manner as the Conversion Rate is adjusted pursuant to Section 10.05 .

(d)      The following table sets forth the Stock Prices and Make-Whole Fundamental Change Effective Dates and the number of Additional Shares, if any, by which the Conversion Rate will be increased for a Holder that converts its Note in connection with a Make-Whole Fundamental Change having such Make-Whole Fundamental Change Effective Date and Stock Price:

In the event that the exact Stock Price or Make-Whole Fundamental Change Effective Date for a Make-Whole Fundamental Change is not set forth in the table above:

(i)      if the Stock Price is between two prices listed in the table or the Make-Whole Fundamental Change Effective Date is between two Make-Whole Fundamental Change Effective Dates listed in the table, the applicable 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 and the earlier and later Make-Whole Fundamental Change Effective Dates based on a 365-day year, as applicable;

(ii)      if the Stock Price is greater than $70.00 per share (subject to adjustment in the same manner and at the same time as the Stock Prices listed in the table), no Additional Shares shall be added to the Conversion Rate; and

(iii)      if the Stock Price is less than $17.03 per share (subject to adjustment in the same manner and at the same time as the Stock Prices listed in the table), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding anything to the contrary in this Section 10.07 , in no event shall the Conversion Rate exceed 58.7199 shares per $1,000 principal amount of Notes, subject to adjustment at the same time and in the same manner as the Conversion Rate pursuant to Section 10.05 (the “Maximum Conversion Rate” ).

(e)      With respect to any Make-Whole Fundamental Change:

(i)      that is described in clause  (b) of the definition Fundamental Change and in which the holders of Common Stock receive only cash in consideration for their shares (a “Cash Merger” ), notwithstanding anything to the contrary in Section 10.03 , the Company shall satisfy its Conversion Obligation with respect to any Note converted at any time following such Cash Merger by delivering to the converting Holder, on the third Business Day immediately following the Conversion Date for such Note, an amount of cash, for each $1,000 principal amount of such Note converted, equal to the product of (A) the Conversion Rate in effect on such Conversion Date (as increased by any Additional Shares pursuant to this Section 10.07 , if any) and (B) the “Stock Price” with respect to such Cash Merger, which shall be the cash amount paid per share to holders of Common Stock in such Cash Merger; or

(ii)      that is not a Cash Merger, (A) the “Stock Price” with respect to such Make-Whole Fundamental Change shall equal 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 related Make-Whole Fundamental Change Effective Date, and (B) for the avoidance of doubt, the Company shall satisfy its Conversion Obligation with respect to any Note converted in connection with such Make-Whole Fundamental Change in accordance with Section 10.03 , based on the Conversion Rate as increased by any Additional Shares pursuant to this Section 10.07 .

Section 10.08      Disclaimer . None of the Trustee, Registrar, Paying Agent or Conversion Agent shall have any duty to determine when an adjustment under this Article X should be made, how it should be made or what it should be. None of the Trustee, Registrar, Paying Agent or Conversion Agent shall be responsible for determining whether any of a Fundamental Change, a Make-Whole Fundamental Change, a VWAP Market Disruption Event, a Trigger Event or a Share Exchange Event shall have occurred. None of the Trustee, the Registrar, the Paying Agent or Conversion Agent shall have any shall be accountable for and makes any representation as to the validity or value (of the kind or amount) of any shares of Common Stock, of any Reference Property or of any other securities, property or assets issued upon conversion of Notes. None of the Trustee, the Registrar, the Paying Agent or Conversion Agent shall be responsible for (i) any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common Stock or stock or share certificates or other securities or property upon the surrender of any Note for the purpose of conversion and (ii) the Company’s failure to comply with this Article X .

None of the Trustee, Registrar, Paying Agent or Conversion Agent shall be responsible for calculating the Trading Price, or determining whether any event contemplated by Section 10.01 has occurred which makes the Notes eligible for conversion, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed herein, in making the same and shall be entitled to presume that no such event has occurred until the Company has delivered to the Trustee an Officer’s Certificate stating that such event has occurred, on which Officer’s Certificate the Trustee may conclusively rely, and the Company agrees to deliver such Officer’s Certificate to the Trustee and any such agent immediately after the occurrence of any such event.

Without limiting the generality of the foregoing, none of the Trustee, Registrar, Paying Agent or Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 9.01(c) relating either to the kind or amount of shares of stock or securities or other property or assets (including cash) receivable for Holders upon the conversion of their Notes after any Share Exchange Event or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01 , may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Each Conversion Agent shall have the same protection under this Section 10.08 as the Trustee, the Registrar and the Paying Agent.

ARTICLE XI.

PAYMENT OF INTEREST

Section 11.01      Payment of Interest . The Company shall pay interest on the Notes at a rate of 2.75% per annum , payable semi-annually in arrears on March 15 and September 15 of each year (each, an “Interest Payment Date” ) or, if any such day is not a Business Day, the immediately following Business Day and no interest on such payment shall accrue in respect of any such delay, commencing September 15, 2014. Interest on the Notes shall accrue from the most recent date to which interest has been paid or duly provided for, or, if no interest has been paid, the Original Issuance Date.

Section 11.02      Defaulted Interest . Any installment of interest that is payable, but is not punctually paid or duly provided for on any Interest Payment Date ( “Defaulted Interest” ), shall forthwith cease to be payable to the Holders in whose names the Notes were registered on the Record Date applicable to such installment of interest. Defaulted Interest (including any interest on such Defaulted Interest) may be paid by the Company, at its election, as provided in Section 11.02(a) or Section 11.02(b) .

(a)      The Company may elect to make payment of any Defaulted Interest (including any interest on such Defaulted Interest) to the Holders in whose names the Notes are registered at the Close of Business on a special record date for the payment of such Defaulted Interest (a “Special Record Date” ), which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest (including any interest on such Defaulted Interest) or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Holders entitled to such Defaulted Interest (including any interest on such Defaulted Interest) as provided in this Section 11.02(a) . Thereupon the Company shall fix a Special Record Date for the payment of such Defaulted Interest (including any interest on such Defaulted Interest), which shall be not more than 15 calendar days and not less than ten calendar days prior to the date of the proposed payment and not less than ten calendar days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee of such Special Record Date and shall cause notice of the proposed payment of such Defaulted Interest (including any interest on such Defaulted Interest) and the Special Record Date therefor to be sent by first-class mail, postage prepaid, to each Holder at such Holder’s address as it appears in the registration books of the Registrar, not less than ten calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest (including any interest on such Defaulted Interest) and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest (including any interest on such Defaulted Interest) shall be paid to the Holders in whose names the Notes are registered at the Close of Business on such Special Record Date and shall no longer be payable pursuant to Section 11.02(b) .

(b)      Alternatively, the Company may make payment of any Defaulted Interest (including any interest on such Defaulted Interest) in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Section 11.02(b) , such manner of payment shall be deemed practicable by the Trustee.

Section 11.03      Interest Rights Preserved . Subject to the foregoing provisions of this Article XI and, to the extent applicable, Section 2.06 and Section 2.07 , each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.
