(4) the Common Stock ceases to be listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors).

A transaction or transactions described in clause (1) or (2) above will not constitute a Fundamental Change, however, if at least 90% of the consideration received or to be received by

holders of Common Stock (excluding cash payments for fractional shares or pursuant to dissenters’ appraisal rights) in connection with such transaction or transactions consists of shares of common stock or common equity interests that are listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market or (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions and as a result of such transaction or transactions such consideration becomes the Reference Property for the Notes, subject to the provisions set forth in Section 5.02.

THE NOTES

Section 2.01 Designation and Terms of Notes. There is hereby created and designated a series of Notes under this Indenture: the title of the Notes shall be “6.125% Convertible Senior Notes Due 2023.”

The aggregate principal amount of the Notes that initially may be authenticated and delivered under this Indenture (the “Initial Notes”) shall be limited to $143,750,000, subject to increase as set forth in Section 2.13.

The Notes shall mature on the Stated Maturity.

Principal and interest (including Additional Interest, if any) on Global Notes shall be payable in the manner set forth in Section 3.01.

The Notes shall be convertible as provided in Article V.

Section 2.02 Execution and Authentication. An Officer shall sign the Notes for the Company by manual or facsimile signature.

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

At any time, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee, in accordance with such Company Order, shall authenticate and deliver such Notes.

A Note shall not be valid until authenticated by the manual or facsimile signature of the Trustee or an authenticating agent. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Notes shall originally be issued only in registered form without coupons and only in denominations of $1,000 of principal amount and any integral multiples of $1,000 in excess thereof.

The Trustee shall authenticate the Notes for original issue in the principal amount of the Notes, upon receipt by the Trustee of a Company Order. Such Company Order may authorize authentication and delivery pursuant to oral or electronic instructions from the Company or its duly authorized agent or agents, which oral instructions shall be promptly confirmed in writing. Each Note shall be dated the date of its authentication.

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

Section 2.03 Registrar and Paying Agent. The Company shall maintain an office or agency where the Notes may be presented or surrendered for payment (“Paying Agent”) and where the Notes may be surrendered for registration of transfer or exchange (“Registrar”). The Registrar shall keep a register with respect to the Notes and to their transfer and exchange.

The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of each Registrar or Paying Agent. If at any time the Company shall fail to maintain any such required Registrar or Paying Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations and surrenders, may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations and surrenders. 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 and exchange of the Notes, and exchange of the Notes into shares of Common Stock (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 also from time to time designate one or more co-registrars or additional paying agents and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the name or address of any such co-registrar or additional paying agent. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company or any of its Affiliates may serve as Registrar or Paying Agent.

The Company hereby appoints the Trustee as the initial Registrar and Paying Agent for the Notes.

Section 2.04 Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust, for the benefit of Holders, or the Trustee, all money held by the Paying Agent for the payment of principal of or interest on the Notes, and will notify the Trustee in writing of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Notes.

Section 2.05 List of Note Holders.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 the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least ten days before each Interest Payment Date and at such other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of the Holders.

Section 2.06 Registration, Transfer and Exchange.

(a) Subject to Section 2.15 hereof and the other provisions of this Section 2.06, 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 Registrar or co-Registrar pursuant to Section 2.03, (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 in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof, 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 2.03 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 into shares of Common Stock or (y) in respect of which a Fundamental Change Repurchase 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 into shares of Common Stock 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 this Section 2.06(b) and Section 2.11. 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 2.03 shall provide to the Trustee such information as the Trustee may 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 (a “Restricted Note”, together with any Common Stock issued upon conversion of the Notes and required to bear the Restricted Stock Legend, collectively, the “Restricted Securities”) 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 Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.06(e), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

(ii) Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the Original Issuance Date, or such shorter period of time as permitted by Rule 144, and (2) such later date, if any, as may be required by applicable law, any certificate evidencing the 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 such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee).

(iii) No transfer of any Restricted Note prior to the Resale Restriction Termination Date will be registered by the Registrar unless the applicable box on the Assignment Form has been checked.

(iv) Any Note 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 (or deemed assigned) a restricted CUSIP number.

The Restricted Securities Legend affixed on any Note will be deemed, in accordance with the terms of the certificate representing such Note, to be removed therefrom upon the Company’s delivery to the Trustee of written notice to such effect, without further action by the Company, the Trustee, the Holder(s) thereof or any other person; at such time, such Note will be deemed to be assigned an unrestricted CUSIP number as provided in the certificate representing such Note, it being understood that the Depositary of any Global Note may require a mandatory exchange or other process to cause such Global Note to be identified by an unrestricted CUSIP number in the facilities of such Depositary. Without limiting the generality of any other provision of this Indenture, the Trustee will be entitled to receive an instruction letter from the Company before taking any action with respect to effecting any such mandatory exchange or other process. The Company and the Trustee reserve the right to require the delivery of such legal opinions, certifications or other evidence as may reasonably be required in order to determine that any proposed transfer of any Note is being made in compliance with the Securities Act and applicable state securities laws. The Company shall be entitled to instruct the Securities Custodian 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 pursuant to Applicable Procedures, and, upon such instruction, the Securities Custodian shall so surrender such Global Note for exchange in accordance with Applicable Procedures; and any new Global Note so exchanged therefor shall not bear the Restricted Securities Legend and shall not be assigned (or deemed assigned) a restricted CUSIP number. The Company shall promptly notify the Trustee in writing upon the occurrence of the expiration of the restrictions on transfer. The Company shall deliver to the Trustee a Company Order for the authentication of the new Global Note which shall not bear the Restricted Securities Legend, an Officers’ Certificate, and an Opinion of Counsel. In addition, any certificate for Common Stock bearing the Restricted Stock Legend as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such certificate for exchange to the transfer agent of the Common Stock, be exchanged for a new certificate for the same number of shares of Common Stock without a Restricted Securities Legend, and the Company shall cause such transfer agent to comply with the foregoing.

Section 2.07 Mutilated, Destroyed, Lost and Stolen NotesIf any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity bond as may be required by each of them to hold itself and any of its agents harmless, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and, upon Company Order the Trustee shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note.

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

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

Section 2.08 Outstanding NotesThe Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest on a Global Note effected by the Trustee in accordance with the provisions hereof and those described in this Section 2.08 as not outstanding.

If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding until the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the Paying Agent (other than the Company, a Subsidiary of the Company or an Affiliate of the Company) holds on the Maturity of the Notes money sufficient to pay such Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue.

Section 2.09 Temporary Securities. Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes upon the Trustee’s receipt of a Company Order. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee upon receipt of a Company Order shall authenticate definitive Notes in exchange for temporary Notes. Until so exchanged, temporary Notes shall have the same rights under this Indenture as the definitive Notes.

Section 2.10 Denominations. The Notes shall be issuable only in fully registered form without interest coupons and only in minimum denominations of $1,000 and any integral multiple thereof.

Section 2.11 Form and Dating.

(a) The Notes and the corresponding Trustee’s certificate of authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this Indenture. The Notes may have notations, legends or endorsements required by law, exchange rule, Applicable Procedures or usage. The Company shall provide

any such notations, legends or endorsements to the Trustee in writing. Each Note shall be dated the date of its authentication.

(b) Global Notes.

(i) All of the Notes shall be issued initially in the form of one or more Notes in global form, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, at its Corporate Trust Office, as Securities Custodian for the depositary, DTC (such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co., or as otherwise instructed by the Depositary duly executed by the Company and authenticated by the Trustee as hereinafter provided (the “Global Note”). A Global Note may be transferred, in whole or in part, only to another nominee of the Depositary or to a successor of the Depositary or its nominee. Beneficial interest in a Global Note may be held directly through the Depositary if such Holder is a participant in the Depositary, or indirectly through organizations that are participants in the Depositary. Transfers between participants shall be effected in the ordinary way in accordance with Applicable Procedures and shall be settled in clearing house funds. The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Securities Custodian and the Depositary as hereinafter provided, subject in each case to compliance with the Applicable Procedures and the provisions of this Indenture.

(ii) Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, purchases, repurchases or conversions of such Notes. Any adjustment of the aggregate principal amount of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee in accordance with Applicable Procedures and shall be made on the records of the Trustee and the Depositary.

(iii) The Depositary, as a Holder, may appoint agents and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under this Indenture.

(iv) Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.02, payment of the principal of, premium, if any, and interest, if any, on any Global Note shall be made to the Holder thereof.

(v) The Company, the Trustee and any Agent shall treat a person as the Holder of such principal amount of Notes represented by a Global Note as shall be specified in a written statement of the Depositary or by the applicable procedures of such Depositary with respect to such Global Note, for purposes of obtaining any consents, declarations, waivers or directions required to be given by the Holders pursuant to this Indenture.

(i) if (x) the Depositary for such Global Note notifies the Company that it is unwilling or unable to continue as Depositary for such Global Note or if at any time such Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case, the Company fails to appoint a successor Depositary registered as a clearing agency under the Exchange Act within 90 days of such event or (y) the Company executes and delivers to the Trustee an Officer’s Certificate to the effect that such Global Note shall be so exchangeable;

(ii) if an Event of Default has occurred and is continuing; or

(iii) if the holder of such beneficial interest and the Company agree to such exchange.

Except as provided in this Section 2.11, a Global Note may not be transferred except as a whole by the Depositary with respect to such Global Note to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such a successor Depositary.

Section 2.12 Conversion Agent. The Company shall maintain an office or agency where Notes may be presented for conversion (the “Conversion Agent”). The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address, of the Conversion Agent. If at any time the Company shall fail to maintain the Conversion Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations may be made at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations.

The Company may have one or more additional conversion agents. The term “Conversion Agent” includes any such additional conversion agents. The Company hereby initially appoints the Trustee Conversion Agent in connection with the Notes.

Section 2.13 Further Issues; Repurchases. The Company may, without the consent of the Holders, reopen this Indenture and issue Additional Notes with the same terms and the same CUSIP number as the Initial Notes (other than differences in the issue price, interest accrued prior to the issue date of such Additional Notes, transfer restrictions and other related matters) in an unlimited aggregate principal amount, provided that if any such Additional Notes are not fungible with the Initial Notes 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 13.07, as the Trustee shall request. In addition, upon the request of the Trustee, the Company shall furnish to the Trustee an Opinion of Counsel which shall cover the matters required by Section 13.07. The Company shall cause any Notes repurchased by the Company pursuant to the foregoing sentence or otherwise (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to

the Trustee for cancellation and such Notes will no longer be Outstanding under the Indenture upon their repurchase.

Section 2.14 Cancellation. The Company at any time may deliver the Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Notes surrendered for transfer, exchange, payment, replacement or cancellation and shall destroy such canceled Notes (subject to the record retention requirement of the Exchange Act and the Trustee) and deliver a certificate of such cancellation to the Company, upon written request of the Company. The Company may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation.

Section 2.15 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 Repurchase Price, for the purpose of exchange and for all other purposes whatsoever, subject to Section 2.06, Section 2.08 and Section 2.11(c), 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 2.16 CUSIP Numbers. The Company in issuing the Notes shall use restricted CUSIP and ISIN numbers (if then generally in use) until such time as the Restricted Securities Legend is removed pursuant to Section 2.06(e). At such time as the Restricted Securities Legend is removed from such Notes pursuant to Section 2.06(e), the Company will use an unrestricted CUSIP number for such Notes, but only with respect to the Notes from which such Restricted Securities Legend was so removed. The Trustee shall use CUSIP numbers in notices as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice and that reliance may be placed only on the other elements of identification printed on the Notes, and any action taken in connection with such notice shall not be affected by any defect in or omission of such numbers.

ARTICLE III.
COVENANTS

Section 3.01 Payment of Principal and Interest; Method of Payment; Defaulted Amounts. The Company covenants and agrees that it shall duly and punctually pay or cause to be paid the principal of and interest (including Additional Interest, if any), on each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes.

(a) The Notes will bear interest at a rate of 6.125% per year. Interest on the Notes will accrue from and including the initial date of issuance, or from the most recent date to which interest has been paid or duly provided for. Interest will be payable semiannually in arrears on each Interest Payment Date, beginning on November 15, 2018. Pursuant to Section 3.08 and Section 7.02 of this Indenture, in certain circumstances, the Holders of Notes shall be entitled to receive Additional Interest.

(b) Interest (including Additional Interest, if any) will be paid to the person in whose name a Note is registered at the Close of Business on May 1 or November 1, as the case may be, immediately preceding the relevant Interest Payment Date, whether or not a Business Day (the “Regular Record Date”). Interest on the Notes will be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.

(c) The Company will pay the principal of certificated Notes at the office or agency designated by the Company for that purpose. The Company has initially designated a Corporate Trust Office of the Trustee as its Paying Agent and Registrar as a place where Notes may be presented for payment for or registration of transfer. The Company will pay any interest on any certificated Note to the Holder of such Note (i) if such Holder holds $1,000,000 or less aggregate principal amount of Notes, by check mailed to such Holder’s registered address, and (ii) if such Holder holds more than $1,000,000 aggregate principal amount of Notes, either (A) by check mailed to such Holder’s registered address or, (B) upon written application by such Holder to the Registrar not later than the relevant Regular Record Date, by wire transfer of immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies the Registrar to the contrary, in writing.

The Company shall pay the principal of, and interest on Global Notes in immediately available funds to the Depositary.

(d) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the rate borne by the Notes from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below:

(i) The Company may elect to make payment of any Defaulted Amounts to the persons in whose names the Notes (or their respective predecessor Notes) are registered at the Close of Business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in writing of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be sent to each Holder at its address as it appears in the Note Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted

Amounts and the special record date therefor having been sent, such Defaulted Amounts shall be paid to the persons in whose names the Notes (or their respective predecessor Notes) are registered at the Close of Business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 3.01(d).

(ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system and the Depositary, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed satisfactory to the Trustee.

Section 3.02 Provisions as to Paying Agent.

(a) If the Company shall appoint a Paying Agent other than the Trustee, or if the Trustee shall appoint such a Paying Agent, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 3.02 that such Paying Agent will, during the continuance of any Default by the Company (or any other obligor upon the Notes) in the making of any payment in respect of the Notes, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent as such.

The Company shall, on or before each due date of the principal of (excluding any Fundamental Change Repurchase Price with respect to), or interest (including Additional Interest, if any) on, the Notes, deposit with the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such principal or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided, however, that if such deposit is made on the due date, such deposit shall 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 the Company’s own Paying Agent, it will, on or before each due date of the principal of or interest (including Additional Interest, if any) 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 or interest (including Additional Interest, if any) so becoming due and will promptly notify the Trustee of any failure to take such action and of any failure by the Company (or any other obligor under the Notes) to make any payment of the principal of or interest (including Additional Interest, if any) on the Notes when the same shall become due and payable.

(c) Anything in this Section 3.02 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 or cause to be paid to the Trustee all sums held in trust by the Company or any Paying Agent hereunder as required by this Section 3.02, such sums to be held by the Trustee upon the trusts herein contained, and upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such sums.

(d) Anything in this Section 3.02 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 3.02 is subject to Section 9.03.

(e) The Trustee shall not be responsible for the actions of any other Paying Agents (including the Company if acting as the Company’s own Paying Agent) and shall have no control of any funds held by such other Paying Agents.

Section 3.03 SEC Filings and Reports. The Company shall file with the Trustee any documents or reports that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (excluding any such information, documents or reports or portions thereof, subject to confidential treatment (or for which the Company has requested confidential treatment) and any correspondence with the SEC) within 15 calendar days after the date the same are required to be filed with the SEC (after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Documents filed by the Company pursuant to the SEC’s “EDGAR” system (or any successor thereto) shall be deemed to constitute “filing” with the Trustee for purposes of this Section 3.03 as of the time such documents are filed via EDGAR, it being understand that the Trustee shall not be responsible for determining whether such filings have been made.

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

Section 3.04 [Reserved].

Section 3.05 Compliance Certificate. To the extent any Notes are outstanding, the Company shall deliver to the Trustee, within 120 calendar days after the end of each fiscal year of the Company (beginning with the year ended December 31, 2018), an Officer’s Certificate stating whether the signers thereof know of any Default that occurred during the previous year.

Section 3.06 Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture or the Notes; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Section 3.07 Delivery of Certain Information. If, at any time, the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issued upon conversion thereof will, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3), upon the written request of any Holder, beneficial owner or prospective purchaser of the Notes or

any shares of Common Stock issued upon the conversion of the Notes, furnish to such Holder, beneficial owner or prospective purchaser the information required to be delivered pursuant to Rule 144A(d)(4) to facilitate the resale of the Notes or such shares of Common Stock pursuant to Rule 144A.

Section 3.08 Rule 144 Additional Interest.

(a) If, at any time during the six-month period beginning on, and including, the date that is six months after the Original Issuance Date, the Company fails to timely file any report that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than current reports on Form 8-K), or the Notes are not otherwise freely tradable pursuant to Rule 144 by holders other than the Company’s Affiliates or holders that were the Company’s Affiliates at any time during the three months immediately preceding the sale (as a result of restrictions pursuant to U.S. securities laws), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period from, and including, the due date of the first missed filing that gives rise to such obligation and continuing or the Notes are not otherwise freely tradable until the earlier of (i) the date that is one year after the Original Issuance Date and (ii) the date all such filings have been made and the Notes are otherwise freely tradable by holders other than the Company’s Affiliates or holders that have been the Company’s Affiliates at any time during the three months immediately preceding without restrictions pursuant to U.S. securities laws or the terms of this Indenture and the Notes. As used in this Section 3.08(a), documents or reports that the Company is required to “file” with the SEC pursuant to Section 13 or 15(d) of the Exchange Act do not include documents or reports that the Company furnishes to the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

(b) If, and for so long as, the Restricted Securities Legend on the Notes specified in Section 2.06 has not been removed (or deemed removed), the Notes are assigned a restricted CUSIP number or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding the sale (without restrictions pursuant to U.S. securities law or the terms of this Indenture or the Notes) as of the 370th day after Original Issuance Date of the Notes, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the aggregate principal amount of the Notes outstanding until the Restricted Securities Legend on the Notes has been removed (or deemed removed), the Notes are assigned an unrestricted CUSIP number and the Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding the sale) (without restrictions pursuant to U.S. securities law or the terms of this Indenture or such Notes). The Restricted Securities Legend on the Notes shall be deemed removed pursuant to the terms of this Indenture as provided in Section 2.06(e), and, at such time, the Notes will, pursuant to, and subject to the provisions of, such Section, be deemed assigned an unrestricted CUSIP number. However, for the avoidance of doubt, Global Notes will continue to bear Additional Interest pursuant to this paragraph until such time as they are identified by an unrestricted CUSIP in the facilities of the Depositary therefor, as a result of completion of such Depositary’s mandatory exchange process or otherwise.

(c) Additional Interest pursuant to this Section 3.08 will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes. Additional Interest pursuant to this Section 3.08 (“Rule 144 Additional Interest”) shall be in addition to any Reporting Additional Interest that may accrue, at the Company’s election, as the sole remedy relating to a Reporting Event of Default under Section 7.02(a). Notwithstanding any other provision in this Indenture, in no event shall Additional Interest accrue on any day (taking into consideration any Additional Interest payable as described in Section 3.08(a), Section 3.08(b) or Section 7.02(a)) at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

(d) If at any time Additional Interest becomes payable by the Company, the Company shall promptly deliver to the Trustee a certificate to that effect and stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no Additional Interest is payable. If the Company has paid Additional Interest directly to the persons entitled to such Additional Interest, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment.

ARTICLE IV.
REPURCHASE AT OPTION OF THE HOLDER

Section 4.01 Repurchase at the Option of the Holder Upon a Fundamental Change.

(a) If a Fundamental Change occurs at any time prior to the Stated Maturity, the Holders shall have the right, at such Holders’ option, to require the Company to repurchase all of such Holders’ Notes, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple of $1,000, on a date (the “Fundamental Change Repurchase Date”, which definition reflects postponement, if any, permitted by the last sentence of this Section 4.01(a)) specified by the Company that is not less than 20 calendar days and not more than 35 calendar days following the date of the Fundamental Change Repurchase Right Notice at a repurchase price (the “Fundamental Change Repurchase Price”) equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date, (unless such Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company will instead pay, on or, at its election, before such Interest Payment Date, the full amount of accrued and unpaid interest to the Holder of record as of such Regular Record Date and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be purchased). Any Notes repurchased by the Company pursuant to this Section 4.01 will be paid for in cash. The Fundamental Change Repurchase Date shall be subject to postponement in order to allow the Company to comply with applicable law.

Repurchases of Notes under this Section 4.01 shall be made, at the option of the Holder thereof, upon:

(i) if the Notes are held in certificated form, delivery to the Trustee (or other Paying Agent appointed by the Company) by a Holder of a written repurchase notice (the “Fundamental Change Repurchase Notice”) or, if the Notes are Global Notes, a notice that complies with the Applicable Procedures, on or before the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date, subject to extension to comply with applicable law; and

(ii) delivery or book-entry transfer of the Notes (together with all necessary endorsements) to the Trustee (or other Paying Agent appointed by the Company) at any time after delivery of the Fundamental Change Repurchase Notice and prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date, subject to extension to comply with applicable law, at the Corporate Trust Office of the Trustee (or other Paying Agent appointed by the Company), such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor; provided that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 4.01 only if the Note so delivered to the Trustee (or other Paying Agent appointed by the Company) shall conform in all respects to the description thereof in the related Fundamental Change Repurchase Notice.

The Fundamental Change Repurchase Notice shall state:

(A) if certificated, the certificate numbers of Notes to be delivered for repurchase;

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

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

provided, however, that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with the Applicable Procedures.

The Trustee (or other Paying Agent appointed by the Company) shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof in accordance with the provisions of subsection (c) of this Section 4.01.

Any certificated Note that is to be repurchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such certificated Note without service charge, a new certificated Note or new certificated Notes, containing identical terms and conditions, each in an authorized denomination in aggregate principal

amount equal to and in exchange for the unrepurchased portion of the principal of the certificated Note so surrendered.

(b) On or before the 20th calendar day after the occurrence of a Fundamental Change, the Company shall provide to all Holders and the Trustee, the Paying Agent (if other than the Trustee) and Conversion Agent (if other than the Trustee) a written notice (the “Fundamental Change Repurchase Right Notice”) of the occurrence of such Fundamental Change and of the resulting repurchase right.

Each Fundamental Change Repurchase Right Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the effective date of the Fundamental Change;

(iii) the last date on which a Holder may exercise its repurchase rights under this Section 4.01;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(vi) the name and address of the Paying Agent and the Conversion Agent (if other than the Trustee);

(vii) the applicable Conversion Rate and, if applicable, any adjustments to the applicable Conversion Rate resulting from such Fundamental Change;

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and

(ix) the procedures the Holder must follow to require the Company to repurchase its Notes under this Section 4.01.

Simultaneously with providing such notice, the Company shall issue a press release or publish the information on its website or through such other public medium as the Company may use at that time.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 4.01.

(c) Holders may withdraw a Fundamental Change Repurchase Notice in whole or in part by means of a written notice of withdrawal delivered to the Paying Agent in accordance with the Fundamental Change Repurchase Right Notice at any time prior to the Close

of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date (the “Fundamental Change Expiration Time”), specifying:

(i) the principal amount of the withdrawn Notes, which must be in principal amounts of $1,000 or an integral multiple thereof;

(ii) if certificated Notes have been issued, the certificate numbers of the withdrawn Notes; and

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

provided, however, that if the Notes are Global Notes, the notice must comply with the Applicable Procedures.

(d) On or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date, the Company shall deposit with the Trustee (or other Paying Agent appointed by the Company or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust) an amount of money sufficient to repurchase on the Fundamental Change Repurchase Date all of the Notes to be repurchased on such date at the Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes properly surrendered for repurchase (and not withdrawn) prior to the Fundamental Change Expiration Time shall be made on the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions to the payment of the Fundamental Change Repurchase Price in this Section 4.01), or (y) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by this Section 4.01 in accordance with the provisions in Section 3.01(c). The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

(e) Subject to a Holder’s right to receive interest on the related Interest Payment Date where the Fundamental Change Repurchase Date, as applicable, falls between a Regular Record Date and the Interest Payment Date to which it relates, if the Trustee (or other Paying Agent appointed by the Company) holds money or securities sufficient to pay the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date, or if extended in order to allow us to comply with applicable law, such later date, then, with respect to the Notes that have been properly surrendered for repurchase and have not been validly withdrawn: (i) such Notes shall cease to be outstanding and interest shall cease to accrue on such Notes on the Fundamental Change Repurchase Date or, if extended in order to allow us to comply with applicable law, such later date, whether or not book-entry transfer of the Notes is made or whether or not the Notes are delivered to the Paying Agent, and (ii) all other rights of the Holders of such Notes shall terminate on the Fundamental Change Repurchase Date or, if extended in order to allow us to comply with applicable law, such later date (other than (x) the right to receive the Fundamental Change Repurchase Price and (y) if the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the related Interest Payment

Date, the right of the Holder of record on such Regular Record Date to receive the accrued and unpaid interest, if any, to, but not including, the Fundamental Change Repurchase Date).

(f) No Notes may be repurchased at the option of Holders on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the applicable Fundamental Change Repurchase Price with respect to such Notes).

(g) In connection with any repurchase offer upon the occurrence of a Fundamental Change, the Company shall, if required:

(i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act that may then be applicable;

(ii) file a Schedule TO or any required schedule, under the Exchange Act; and

(iii) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes,

in each case, so as to permit the rights and obligations under this Article IV to be exercised in the time and in the manner specified in this Indenture, subject to postponement in order to allow us to comply with applicable law. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture relating to the Company’s obligations to purchase the Notes upon a Fundamental Change, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under such provisions of this Indenture by virtue of such conflict.

(h) Notwithstanding anything to the contrary in this Article IV, the Company will not be required to repurchase, or make an offer to repurchase, the Notes upon a Fundamental Change if a third party makes such an offer to repurchase in the manner, at the times and otherwise in compliance with the requirements set forth in this Article IV applicable to an offer to repurchase made by the Company and such third party purchases all Notes properly tendered and not validly withdrawn under such offer.

ARTICLE V.
CONVERSION OF NOTES

Section 5.01 Conversion Privilege.

(a) Subject to and upon compliance with the provisions of this Article V, each Holder shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note:

(i) subject to satisfaction of the conditions described in Section 5.01(b), at any time prior to the Close of Business on the Business Day immediately preceding February 15, 2023 under the circumstances and during the periods set forth in Section 5.01(b);

(ii) on or after February 15, 2023, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Stated Maturity;

in each case, at an initial conversion rate of 43.9386 shares of Common Stock (subject to adjustment as provided in Section 5.04 and, if applicable, Section 5.03, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to the settlement provisions of Section 5.02, the “Conversion Obligation”).

Notwithstanding any other provision of the Notes or this Indenture, no Holder of Notes will be entitled to receive shares of Common Stock upon conversion of such Notes to the extent (but only to the extent) that such receipt would cause a violation of the Ownership Limitation. Any purported delivery of shares of Common Stock upon conversion of Notes will be void and have no effect to the extent (but only to the extent) that such delivery would result in a violation of the Ownership Limitation. If any delivery of shares of Common Stock owed to a Holder upon conversion of Notes is not made, in whole or in part, as a result of the limitations described in this paragraph, the Company’s obligation to make such delivery shall not be extinguished, and the Company shall deliver such shares as promptly as practicable after the applicable Holder gives notice to the Company and the Company determines that such delivery would not result in a violation of the Ownership Limitation.

(b) (i) Prior to the Close of Business on the Business Day immediately preceding February 15, 2023, a Holder may surrender all or any portion of its Notes (that is $1,000 principal amount or an integral multiple thereof) for conversion at any time during the five Business Day period after any five consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder in accordance with the procedures and conditions described below in this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each such Trading Day, subject to compliance with the following procedures concerning the Bid Solicitation Agent’s obligation to make a Trading Price determination.

(A) The Bid Solicitation Agent (if other than the Company) shall have no obligation to determine the Trading Price per $1,000 principal amount of the Notes unless the Company has requested such determination, and the Company shall have no obligation to make such request (or, if the Company is acting as Bid Solicitation Agent, the Company shall have no obligation to determine the Trading Price) unless a Holder of at least $1,000,000 in aggregate principal amount of Notes requests in writing that the Company makes such a determination and provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day. At the time of such request, the Company shall instruct the Bid Solicitation Agent (if other than the Company) to determine, or if the Company is acting as Bid Solicitation Agent, the Company shall determine, the Trading Price per $1,000 principal amount of the Notes beginning on the next Trading Day following the receipt of such evidence and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the

product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day.

(B) If the Trading Price condition has been met, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee). If, at any time after the Trading Price condition has been met, the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on such Trading Day, the Company shall so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee).

(C) If (x) the Company is not acting as Bid Solicitation Agent, and the Company does not, when it is required to, instruct the Bid Solicitation Agent to obtain bids, or if the Company gives such instruction to the Bid Solicitation Agent and the Bid Solicitation Agent fails to make such determination, or (y) if the Company is acting as Bid Solicitation Agent and it fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of the Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Conversion Rate on each Trading Day of such failure.

(ii) If, prior to the Close of Business on the Business Day immediately preceding February 15, 2023, the Company elects to:

(A) issue to all or substantially all holders of Common Stock any rights, options or warrants (other than pursuant to a stockholders rights plan, so long as such rights have not separated from the shares of Common Stock) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock, at a price per share that is less than the average of the Last Reported Sale Prices of Common Stock for the 10 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 Common Stock the Company’s assets, securities or rights to purchase securities of the Company (other than pursuant to a stockholders rights plan, so long as such rights have not separated from the shares of Common Stock), which distribution has a per share value, as reasonably determined by the Board of Directors or a committee thereof, exceeding 10% of the Last Reported Sale Price of Common Stock on the Trading Day immediately preceding the date of announcement of such distribution,

then, in either case, the Company shall notify all Holders, the Trustee and the Conversion Agent (if other than the Trustee) at least 50 Scheduled Trading Days prior to the Ex-Dividend Date of such issuance or distribution. Once the Company has given such notice, the Holders may surrender all or any portion of their Notes (that is $1,000 in principal amount or an integral multiple thereof) for conversion at any time until the earlier of (1) the Close of Business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution; and (2) the Company’s announcement that such

issuance or distribution will not take place. A Holder may not convert its Notes pursuant to this Section 5.01(b)(ii) if such Holder participates in such issuance or distribution (other than in the case of a stock split or stock combination), at the same time and upon the same terms as holders of Common Stock and solely as a result of holding Notes, without having to convert its Notes as if such Holder held a number of shares of Common Stock equal to (x) the applicable Conversion Rate multiplied by (y) the principal amount (expressed in thousands) of Notes held by such Holder.

(iii) If, prior to the Close of Business on the Business Day immediately preceding February 15, 2023:

(A) a Fundamental Change occurs;

(B) a Make-Whole Fundamental Change occurs; or

(C) the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole (other than with one of the Company’s wholly-owned Subsidiaries, unless such transaction also constitutes a Fundamental Change or Make-Whole Fundamental Change), in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets (other than any such transaction to which the Company is a party solely for purpose of changing its jurisdiction of incorporation, and which results in a reclassification, conversion or exchange of Common Stock solely into common stock of the surviving entity, excluding cash payments for fractional shares),

then, in each case, the Holders may surrender all or any portion of their Notes (that is $1,000 in principal amount or an integral multiple thereof) for conversion at any time from or after the date that is 50 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day immediately following the day the Company gives notice of such transaction) until the earlier of (x) 35 Trading Days after the effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the Close of Business on the Business Day immediately preceding the related Fundamental Change Repurchase Date and (y) the second Scheduled Trading Day immediately preceding the Stated Maturity.

The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) as promptly as practicable following the date the Company publicly announces such transaction, but in no event less than 50 Scheduled Trading Days prior to the anticipated effective date of such transaction; provided, however, that if the Company does not have knowledge of such transaction at least 50 Scheduled Trading Days prior to the anticipated effective date of such transaction, the Company shall provide such notice within three Business Days of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction.

(iv) Prior to the Close of Business on the Business Day immediately preceding February 15, 2023, a Holder may surrender all or any portion of its Notes (that is $1,000 in principal amount or an integral multiple thereof) for conversion at any time during any

calendar quarter commencing after the calendar quarter ending on September 30, 2018 (and only during such calendar quarter), if the Last Reported Sale Price of Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter is greater than 110% of the Conversion Price on each applicable Trading Day.

Section 5.02 Conversion Procedure; Settlement Upon Conversion.

(a) Subject to this Section 5.02, Section 5.03(b) and Section 5.07(a), upon conversion of any Note, the Company shall, at its election, pay or deliver, as the case may be, to the converting Holder, in full satisfaction of its Conversion Obligation, cash (“Cash Settlement”), shares of Common Stock (“Physical Settlement”) or a combination of cash and shares of Common Stock (“Combination Settlement”), as set forth in this Section 5.02.

(i) The Company will use the same Settlement Method for all conversion occurring on the same Conversion Date, but will not have any obligation to use the same Settlement Method with respect to conversions that occur on different Conversion Dates. Notwithstanding the foregoing, all conversions with a Conversion Date occurring on or after February 15, 2023 will be settled using the same Settlement Method, and the Company will notify Holders of that Settlement Method no later than February 15, 2023.

(ii) If the Company elects a Settlement Method, the Company shall deliver notice to Holders so converting through the Conversion Agent (if other than the Trustee) and the Trustee of such Settlement Method the Company has selected no later than the Close of Business on the Trading Day immediately following the related Conversion Date, or with respect to conversions with a Conversion Date occurring on or after February 15, 2023, no later than February 15, 2023. If the Company does not timely elect a Settlement Method with respect to a Conversion Date, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement with respect to such Conversion Date and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligations, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. If the Company has elected Combination Settlement in respect of any conversion but does not timely notify the converting Holders of the Specified Dollar Amount per $1,000 principal amount of Notes, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000.

(iii) The cash, shares of Common Stock or combination of cash and shares of Common Stock payable or deliverable by the Company in respect of any conversion of Notes (the “Settlement Amount”) shall be computed by the Company as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, a number of shares of Common Stock equal to the Conversion Rate on the Conversion Date (plus cash in lieu of any fractional share of Common Stock issuable upon conversion);

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash in an amount equal to the sum of the Daily Conversion Values for each of the 40 consecutive VWAP Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay and deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive VWAP Trading Days during the related Observation Period (plus cash in lieu of any fractional share of Common Stock issuable upon conversion).

If more than one Note shall be surrendered for conversion at any one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes so surrendered.

(iv) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last VWAP Trading Day of the related Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and, if applicable, the amount of cash payable in lieu of any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and, if applicable, the amount of cash payable in lieu of fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b)

(i) To convert a beneficial interest in a Global Note (which conversion is irrevocable), the holder of such beneficial interest must:

(A) comply with the Applicable Procedures;

(B) if required, pay funds equal to all documentary, stamp or similar issue or transfer tax owed as set forth in Section 5.02(d) and Section 5.02(e); and

(C) if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 5.02(g); and

(ii) To convert a certificated Note, the Holder must:

(A) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “Notice of Conversion”) and such Note to the Conversion Agent;

(B) if required, furnish appropriate endorsements and transfer documents;

(C) if required, pay funds equal to all documentary, stamp or similar issue or transfer tax owed as set forth in Section 5.02(d) and Section 5.02(e); and

(D) if required, pay funds equal to any interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 5.02(g).

The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article V on the Conversion Date for such conversion or, if notice on such date is not feasible given the nature of the conversion, promptly thereafter.

If a Holder has delivered a Fundamental Change Repurchase Notice with respect to a Note, such Holder may not convert that Note until such Holder has validly withdrawn such Fundamental Change Repurchase Notice (or, in the case of a Global Note, has complied with the Applicable Procedures with respect to such a withdrawal) in accordance with the terms of Section 4.01. If a Holder has delivered a Fundamental Change Repurchase Notice, such Holder’s right to withdraw such notice and convert the Notes that are subject to repurchase will terminate at the Close of Business on the Business Day immediately preceding the relevant Fundamental Change Repurchase Date.

(c) A Note shall be deemed to have been converted immediately prior to the Close of Business on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in Section 5.02(b) above. Subject to the provisions of Section 5.03(b) and Section 5.07(a), the Company shall pay or deliver, as the case may be, the Settlement Amount due in respect of the Conversion Obligation on:

(i) the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement (provided that, with respect to any conversion following the Regular Record Date immediately preceding the Stated Maturity, the Company will settle any such conversion on the Stated Maturity or, if such day is not a Business Day, the first Business Day immediately following the Stated Maturity); or

(ii) the second Business Day immediately following the last VWAP Trading Day of the relevant Observation Period, if the Company elects Cash Settlement or if the Company elects or is deemed to elect Combination Settlement.

If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary, as the case may be, for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(d) In case any certificated Note shall be surrendered for partial conversion, in $1,000 principal amount or an integral multiple thereof, the Company shall execute and upon

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

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

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

(g) Upon conversion of a Note, the converting Holder shall not receive any separate cash payment representing accrued and unpaid interest, if any, except as set forth in the paragraph below. The Company’s payment or delivery, as the case may be, of the Settlement Amount upon conversion of any Note shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest shall be deemed to be paid first out of the cash paid upon such conversion.

Notwithstanding the immediately preceding paragraph, if Notes are converted after the Close of Business on a Regular Record Date for the payment of interest, but prior to the Open of Business on the immediately following Interest Payment Date, Holders of such Notes shall receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the Close of Business on any Regular Record Date to the Open of Business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable on the Notes so converted on such Interest Payment Date (regardless of whether the converting Holder was the Holder of record on the corresponding Regular Record Date); provided that no such payment need be made:

(i) if the Notes are surrendered for conversion following the Regular Record Date immediately preceding the Stated Maturity;

(ii) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or

(iii) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

Therefore, for the avoidance of doubt, all Holders of record as of the Close of Business on the Regular Record Date immediately preceding the Stated Maturity and any Fundamental Change Repurchase Date as described in clause (ii) above shall receive and retain the full interest payment due on the Stated Maturity or other applicable Interest Payment Date regardless of whether their Notes have been converted following such Regular Record Date.

(h) The person in whose name any shares of Common Stock delivered upon conversion is registered shall become the holder of record of such shares as of the Close of Business on (i) the relevant Conversion Date if the Company elects Physical Settlement or (ii) the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to elect Combination Settlement. Upon a conversion of Notes, such person shall no longer be a Holder of such Notes surrendered for conversion; provided that (a) the converting Holder shall have the right to receive the Settlement Amount due upon conversion and (b) in the case of a conversion between a Regular Record Date and the corresponding Interest Payment Date, the Holder of record as of the Close of Business on such Regular Record Date shall have the right to receive the interest payable on such Interest Payment Date, in accordance with Section 5.02(g).

(i) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion in an amount based on (i) the Daily VWAP on the relevant Conversion Date if the Company elects Physical Settlement or (ii) the Daily VWAP on the last VWAP Trading Day of the relevant Observation Period if the Company elects or is deemed to elect Combination Settlement. For each Note surrendered for conversion, if the Company has elected (or is deemed to elect) Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and, if applicable, any fractional share remaining after such computation shall be paid in cash.

Section 5.03 Increase in Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change.

(a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Stated Maturity and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “Additional Shares”), as described below. A

conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Conversion Date occurs during the period from, and including, the Effective Date of the Make-Whole Fundamental Change to, and including, the Close of Business on the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the subclause (a) of the proviso in clause (2) of the definition of “Fundamental Change,” the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “Make-Whole Fundamental Change Period”). The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective Date and issue a press release announcing such Effective Date (the “Make-Whole Fundamental Change Company Notice”).

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy its Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 5.02; provided, however, that, if the consideration for the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to (i) the Conversion Rate (including any increase to reflect the Additional Shares as described in this Section 5.03), multiplied by (ii) such Stock Price. In such event, the Conversion Obligation shall be determined and paid to Holders in cash on the second Business Day following the Conversion Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below in Section 5.03(e), based on: (x) the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “Effective Date”), and (y) the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change (the “Stock Price”). If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, during such five Trading Day period.

(d) The Stock Prices set forth in the column headings of the table below in Section 5.03(e) shall be adjusted as of any date on which the Conversion Rate is otherwise adjusted. The adjusted Stock Prices shall equal (i) the Stock Prices applicable immediately prior to such adjustment, multiplied by (ii) a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the

denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below in Section 5.03(e) shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 5.04.

(e) The following table sets forth the number of Additional Shares by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 5.03 for each Stock Price and Effective Date set forth below:

	Stock Price
Effective date	$20.69	$21.00	$21.50	$22.00	$22.50	$22.76	$23.00	$23.50	$24.00	$26.00
May 18, 2018	4.3939	3.8495	3.0372	2.3064	1.6609	1.3603	1.1048	0.6400	0.2771	0.1427
May 15, 2019	4.3939	3.7633	2.9330	2.1882	1.5364	1.2359	0.9830	0.5328	0.1979	0.0841
May 15, 2020	4.3939	3.7457	2.8879	2.1218	1.4556	1.1520	0.8987	0.4540	0.1392	0.0449
May 15, 2021	4.3939	3.6719	2.7795	1.9895	1.3138	1.0105	0.7613	0.3366	0.0617	0.0000
May 15, 2022	4.3939	3.4552	2.5042	1.6809	1.0067	0.7206	0.4961	0.1532	0.0000	0.0000
May 15, 2023	4.3939	3.6804	2.5730	1.5159	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000

The exact Stock Price and Effective Date may not be set forth in the table above, in which case

(i) if the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares by which the Conversion Rate shall be increased 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 Effective Dates, as applicable, based on a 365- or 366-day year, as applicable;

(ii) if the Stock Price is greater than $26.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $20.69 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event shall the Conversion Rate per $1,000 principal amount of Notes exceed 48.3325 shares of Common Stock, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 5.04.

(f) Nothing in this Section 5.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 5.04 in respect of a Make-Whole Fundamental Change.

Section 5.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a stock split or stock combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes,

in any of the transactions described in this Section 5.04, without having to convert their Notes, as if they held a number of shares of Common Stock equal to (i) the Conversion Rate, multiplied by (ii) the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all shares of Common Stock, or if the Company effects a stock split or stock combination (in each case, excluding a distribution solely pursuant to a Common Stock Change Event, as to which the provisions of Section 5.07 will apply), the Conversion Rate shall be adjusted based on the following formula:

where,

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

CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or effective date, as applicable;

OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or effective date, as applicable, before giving effect to such dividend, distribution, stock split or stock combination, as applicable; and

OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination, as applicable.

Any adjustment made under this Section 5.04(a) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such stock split or stock combination, as applicable. If any dividend or distribution of the type described in this Section 5.04(a) is declared but is not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors or a committee thereof determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or announced.

(b) If the Company issues to all or substantially all holders of Common Stock any rights, options or warrants (other than rights issued or otherwise distributed pursuant to a stockholders rights plan, as to which the provisions described in Section 5.04(c) and Section 5.11 shall apply) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of Common Stock for the 10 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 increased based on the following formula:

where,

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

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

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

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

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

Any increase made under this Section 5.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if no such rights options or warrants are exercised prior to their expiration, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this Section 5.04(b) and Section 5.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at a price per share less than such average of the Last Reported Sale Prices of Common Stock for the 10 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 price payable to exercise such rights, option or warrants, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any

amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors or a committee thereof.

(c) (A) If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of Common Stock, excluding:

(i) dividends, distributions or issuances (including stock splits) as to which an adjustment was effected pursuant to Section 5.04(a) or Section 5.04(b);

(ii) rights issued or otherwise distributed pursuant to any stockholders rights plan of the Company (other than pursuant to Section 5.11);

(iii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 5.04(d);

(iv) cash dividends that do not result in an adjustment to the Conversion Rate pursuant to Section 5.04(d);

(v) a distribution solely pursuant to a Common Stock Change Event, as to which Section 5.07 will apply; and

(vi) Spin-Offs as to which the provisions set forth below in this Section 5.04(c)(B) shall apply

(any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities of the Company, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

where,

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

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

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

FMV

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

Any increase made under the portion of this Section 5.04(c)(A) above shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or on the basis of the rights, options or warrants actually exercised before their expiration date, as applicable.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of Common Stock receive the Distributed Property, the amount and kind of Distributed Property that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for the distribution.

(B) Where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, and such Capital Stock or equity interest is, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

where,

CR0	=	the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of the Spin-Off;

CR1	=	the Conversion Rate in effect immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off;

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

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

The adjustment to the Conversion Rate under this Section 5.04(c)(B) shall be calculated as of the Close of Business on the last Trading Day of the Valuation Period but will be given effect immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, the references to “10” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, subject to the immediately succeeding sentence, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, the references to “10” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Ex-Dividend Date for such Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed replaced, solely in respect of that conversion, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last VWAP Trading Day of such Observation Period. If any dividend or distribution that constitutes a Spin-Off is declared but not so paid or made, the Conversion Rate shall be immediately decreased, effective as of the date on which the Board of Directors or a committee thereof determines not to make such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or announced.

For purposes of this Section 5.04(c) (and subject in all respect to Section 5.11), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”):

(i) are deemed to be transferred with such shares of the Common Stock;

(ii) are not exercisable; and

(iii) are also issued in respect of future issuances of the Common Stock,

shall be deemed not to have been distributed for purposes of this Section 5.04(c) (and no adjustment to the Conversion Rate under this Section 5.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 5.04(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 5.04(c) was made:

(I) 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

(II) 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 5.04(a), Section 5.04(b) and this Section 5.04(c), any dividend or distribution to which this Section 5.04(c) is applicable that also includes one or both of:

(i) a dividend or distribution of shares of Common Stock to which Section 5.04(a) is applicable (the “Clause A Distribution”); or

(ii) a dividend or distribution of rights, options or warrants to which Section 5.04(b) is applicable (the “Clause B Distribution”),

then:

(I) 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 5.04(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 5.04(c) with respect to such Clause C Distribution shall then be made; and

(II) 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 5.04(a) and Section 5.04(b) with respect thereto shall then be made, except that, if determined by the Company (x) 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 (y) 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 5.04(a) or “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” within the meaning of Section 5.04(b).

(d) If any cash dividend or distribution is made to all or substantially all holders of Common Stock, to the extent that the aggregate of all such cash dividends or distributions paid in any quarter exceeds the DTA for such quarter, the Conversion Rate shall be increased based on the following formula:

where,

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

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

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

DTA	=	the DTA in effect on the Ex-Dividend Date for such dividend or distribution; and

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

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such cash dividend or distribution.

Any increase made pursuant to this Section 5.04(d) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors or a committee thereof determines not to make or pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Day period (the “Averaging Period”) commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer

(such date, the “Expiration Date”), the Conversion Rate shall be increased based on the following formula:

where,

CR0	=	the Conversion Rate in effect immediately prior to the Close of Business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date;

CR1	=	the Conversion Rate in effect immediately after the Close of Business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date;

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

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

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

SP1	=	the average of the Last Reported Sale Prices of Common Stock over the Averaging Period.

The adjustment to the Conversion Rate under this Section 5.04(e) shall occur as of the Close of Business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the Expiration Date; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Expiration Date of such tender or exchange offer and such Conversion Date in determining the Conversion Rate and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Expiration Date

of such tender or exchange offer and such Trading Day in determining the Conversion Rate as of such Trading Day. In addition, if the Trading Day next succeeding the Expiration Date is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely 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 of such tender or exchange offer to, and including, last VWAP Trading Day of such Observation Period.

To the extent such tender or exchange offer is announced but not consummated (including as a result of being precluded from consummating such tender or exchange offer under applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had the adjustment been made on the basis of only the purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender or exchange offer.

(f) Notwithstanding anything to the contrary in this Section 5.04 or any other provision of this Indenture or the Notes, in respect of a Physical Settlement or Combination Settlement of any conversion, if any adjustment to the Conversion Rate described in Section 5.04(a) through Section 5.04(e) above becomes effective on any Ex-Dividend Date, a Holder that has converted its Notes would:

(i) receive shares of Common Stock based on the Conversion Rate as so adjusted in respect of such conversion (in the case of Physical Settlement) or in respect of any Trading Day in the relevant Observation Period (in the case of Combination Settlement); and

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

then, in lieu of receiving shares of Common Stock at such adjusted Conversion Rate, such holder shall receive a number of shares of Common Stock based on the unadjusted Conversion Rate in respect of such conversion (in the case of Physical Settlement) or such Trading Day (in the case of Combination Settlement) and will participate, as a record holder of such shares, in the related dividend, distribution or other event giving rise to the adjustment.

(g) Notwithstanding anything to the contrary in the Indenture or the Notes to the contrary, if the application of the formulas set forth in Section 5.04(a) through Section 5.04(e) would result in a decrease in the Conversion Rate, then no adjustment to the Conversion Rate shall be made (other than as a result of a reverse stock split or stock combination pursuant to Section 5.04(a) or the reversal of an increase to the Conversion Rate where the relevant event did not occur).

(h) All calculations and other determinations under this Article V shall be made by the Company and all adjustments to the Conversion Rate shall be made to the nearest one-ten thousandth (1/10,000th) of a share.

(i) The Company shall not be required to make an adjustment pursuant to Section 5.04(a) through Section 5.04(e) unless such adjustment would result in a change of at least 1% of the then effective Conversion Rate. However, the Company shall carry forward any adjustment that the Company would otherwise have to make and take that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to the Notes (i) annually on the anniversary of the first issuance date of the Notes, (ii) in connection with any subsequent adjustment to the Conversion Rate that, together with all carried-forward adjustments, would constitute a change of at least 1% in the then-effective Conversion Rate, and (iii) (x) on the Conversion Date for any Notes (in the case of Physical Settlement) and (y) on each VWAP Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement).

(j) In addition to those adjustments required by Section 5.04(a) through Section 5.04(e), the Company, subject to the applicable listing standards of The New York Stock Exchange, is permitted to increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors or a committee thereof determines that such increase would be in the Company’s best interest. In addition, subject to the applicable listing standards of The New York Stock Exchange, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Conversion Rate is increased pursuant to either of the preceding two sentences, the Company shall send to the Holder of each Note at its last address appearing on the Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(k) The Company shall not adjust the Conversion Rate except as stated in this Indenture, including, for the avoidance of doubt, for the issuance of shares of Common Stock or any 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. In addition, notwithstanding anything to the contrary in this Article V and for the avoidance of doubt, the Conversion Rate shall not be adjusted:

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

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

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

(iv) upon the issuance of Common Stock at a price below the Conversion Price or otherwise;

(v) for a third-party tender offer;

(vi) upon the repurchase of any shares of Common Stock pursuant to an open-market share purchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender offer or exchange offer of the nature described in Section 5.04(e);

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

(viii) for accrued and unpaid interest, if any.

(l) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall send such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Register of this Indenture. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(m) For purposes of this Section 5.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

(n) If, in connection with any adjustment or the non-occurrence of an adjustment to the Conversion Rate as set forth in Section 5.03 or this Section 5.04, a Holder shall be deemed for U.S. federal tax purposes to have received a distribution and the Company determines it is required to collect withholding tax with respect to any such deemed distribution, the Company may withhold from cash payments of interest in accordance with the provisions of Section 2.03 hereof or from cash and Common Stock, if any, otherwise deliverable to a Holder upon a conversion of Notes in accordance with the provisions of Section 5.02 hereof or repurchase of a Note in accordance with the provisions of Article IV hereof.

Section 5.05 Adjustment of Prices. Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including, without limitation, an Observation Period and the period, if any, for determining the Stock Price

for purposes of a Make-Whole Fundamental Change), the Board of Directors or a committee thereof shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 5.06 Shares to be Fully Reserved. The Company shall reserve, on or prior to the date of this Indenture, and from time to time as may be necessary, out of its authorized but unissued shares, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes are presented for conversion (assuming that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement is applicable, and including the maximum number of Additional Shares that could be included in the Conversion Rate for a conversion in connection with a Make-Whole Fundamental Change).

Section 5.07 Effect of Recapitalizations, Reclassifications and Changes of Common Stock.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than a change in par value, or from par value to no par value or from no par value to par value, or changes resulting from a split, subdivision or combination of Common Stock);

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

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

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Common Stock Change Event” and such stock, other securities, other property or assets (including any cash or any combination thereof), the “Reference Property” and the amount and the kind of Reference Property that a holder of one share of Common Stock immediately prior to such Common Stock Change Event would be entitled to receive upon the occurrence of such Common Stock Change Event, a “Reference Property Unit”), then the Company, or the successor or purchasing corporation, as the case may be, will execute with the Trustee, without the consent of the Holders, a supplemental indenture providing that, at and after the effective time of such Common Stock Change Event, the right to convert each $1,000 principal amount of Notes will be changed into a right to convert such principal amount of Notes into the kind and amount of Reference Property that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Common Stock Change Event would have been entitled to receive upon such Common Stock Change Event; provided,

however, that at and after the effective time of such Common Stock Change Event:

(A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 5.02; and

(B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 5.02 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 5.02 shall instead be deliverable in Reference Property Units that a holder of that number of shares of Common Stock would have received in such Common Stock Change Event and (III) the Daily VWAP shall be calculated based on the value of a Reference Property Unit; provided, however, that if the holders of Common Stock receive only cash in such Common Stock Change Event, then for all conversions that occur after the effective time of such Common Stock Change Event (x) the consideration due upon conversion of each $1,000 principal aggregate amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 5.03), multiplied by the price paid per share of Common Stock in such Common Stock Change Event and (y) the Company shall satisfy the Conversion Obligation by paying such cash to the converting Holder on the second Business Day immediately following the Conversion Date.

If the Common Stock Change 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 composition of the Reference Property Unit shall be deemed to be based on: (A) the weighted average, per share of Common Stock, of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election; and (B) if no holder of Common Stock affirmatively make such an election, the types and amounts of consideration actually received, per share of Common Stock, by the holder of Common Stock. The Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of the weighted average as soon as reasonably practicable after such determination is made.

Such supplemental indenture shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article V. If the Reference Property in respect of any Common Stock Change Event includes shares of stock, other securities or other property or assets (including any combination thereof) of an entity other than the Company or the successor or purchasing corporation, as the case may be, in such Common Stock Change Event, then such other entity, if it is a party to such Common Stock Change Event, shall also execute such supplemental indenture, and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders, including the right of Holders to require the Company to repurchase their Notes upon a Fundamental Change in accordance with Article IV, as the Board of Directors or a committee thereof shall reasonably considers necessary by reason of the foregoing.

(b) In the event the Company shall execute a supplemental indenture pursuant to Section 5.07(a), the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or other assets (including any combination thereof) that will comprise the Reference Property after any such Common Stock Change Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly send notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be sent to each Holder, at its address appearing on the Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) In connection with any adjustment of the Conversion Rate as described in this Section 5.07, the Company will also adjust the DTA based on the number of shares of Common Stock comprising the Reference Property and (if applicable) the value of any non-stock consideration comprising the Reference Property. If the Reference Property is solely composed of non-stock consideration the DTA will be zero.

(d) The Company shall not become a party to any Common Stock Change Event unless its terms are consistent with this Section 5.07. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, as set forth in Section 5.01 and Section 5.02 prior to the effective date of such Common Stock Change Event.

(e) The above provisions of this Section shall similarly apply to successive Common Stock Change Events.

Section 5.08 Certain Covenants.

(a) The Company covenants that all shares of Common Stock issued upon conversion of Notes shall be duly authorized, fully paid and non-assessable and free from all preemptive or similar rights of any securityholder of the Company and, except for any transfer taxes payable by the Company or a Holder, as the case may be, pursuant to Sections 5.02(d) and 5.02(e), free from all transfer or similar taxes, liens, charges and adverse claims as the result of any action by the Company.

(b) The Company shall comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of the Notes, including 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 shall, to the extent then permitted by the rules and interpretations of the SEC, secure such registration or approval, as the case may be.

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

Section 5.09 Responsibility of the Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 5.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 5.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Article XI, may accept (without any independent investigation) 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. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 5.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 5.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 5.01(b). The parties hereto agree that all notices to the Trustee or the Conversion Agent under this Article V shall be in writing.

Section 5.10 Notice to Holders Prior to Certain Actions. In case of any:

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Conversion Rate pursuant to Section 5.04 or Section 5.11;

(b) Common Stock Change Event or any consolidation, merger, sale, assignment, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article VIII; or

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be sent to each Holder at its address appearing on the Register, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Common Stock Change Event, any consolidation, merger, sale, assignment, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article VIII, or any dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Common Stock Change Event, consolidation, merger, sale, assignment, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article VIII, dissolution, liquidation or winding-up; provided, however, that if on such date, the Company does not have knowledge of such event or the adjusted Conversion Rate cannot be calculated, the Company shall deliver such notice as promptly as practicable upon obtaining knowledge of such event or information sufficient to make such calculation, as the case may be, and in no event later than the effective date of such adjustment. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Common Stock Change Event, or any consolidation, merger, sale, assignment, lease, conveyance or other transfer or disposition of all or substantially all assets in accordance with Article VIII, dissolution, liquidation or winding-up.

Section 5.11 Stockholder Rights Plans. To the extent that the Company has a rights plan in effect upon conversion of the Notes, Holders that convert their Notes shall receive, to the extent, if at all, such Holders receive any shares of Common Stock upon such conversion, rights under the rights plan, if any, and any certificate representing the share of Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such rights plan, as the same may be amended from time to time. However, if prior to any conversion, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable rights plan, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of shares of Common Stock, Distributed Property pursuant to Section 5.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

ARTICLE VI.
NO OPTIONAL REDEMPTION

Section 6.01 No Optional Redemption. The Notes shall not be redeemable by the Company prior to the Stated Maturity, and no sinking fund is provided for the Notes.

ARTICLE VII.

(vii) default by the Company or any of the Company’s Significant Subsidiaries with respect to any mortgage, agreement or other instrument under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed (other than non-recourse debt of a Subsidiary of the Company) in excess of $25,000,000 (or its foreign currency equivalent) in the aggregate, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, in each case, after the expiration of any applicable grace period, and such acceleration shall not have been rescinded or annulled or such failure to pay shall not have been cured or waived, as the case may be, within 30 calendar days after written notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% of the principal amount of the Notes then outstanding;

(B) appoints a custodian of the Company or any Significant Subsidiary of the Company or for all or substantially all of the property of the Company or any Significant Subsidiary of the Company; or

the order or decree remains unstayed and in effect for 60 consecutive days.

Section 7.02 Acceleration of Maturity; Additional Interest.

(a) If an Event of Default occurs and is continuing (other than an Event of Default described in Section 7.01(a)(ix) or (x) with respect to the Company), the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Notes by written notice to the Company and the Trustee, may, and the Trustee at the written request of such Holders shall, declare 100% of the principal of and accrued and unpaid interest, if any, on all Notes to be due and payable. Upon such a declaration of acceleration, such principal and accrued and unpaid interest, if any, shall become due and payable immediately. In case of an Event of Default arising out of Sections 7.01(a)(ix) and (x) with respect to the Company (and not with respect to any Significant Subsidiary of the Company), 100% of the aggregate principal amount and accrued and unpaid interest shall automatically become due and payable without notice from the Trustee or Holders.

Notwithstanding anything in this Indenture or in the Notes to the contrary, at the election of the Company, the sole remedy with respect to an Event of Default relating to the failure by the Company to comply with its obligations as set forth in Section 3.03 (any such Event of Default, a “Reporting Event of Default”) shall, for the first 180 days after the occurrence of such Reporting Event of Default consist exclusively of the right to receive additional interest (the “Reporting Additional Interest”) on the Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the date on which such Reporting Event of Default first occurred and ending on the earlier of (x) the date on which such Reporting Event of Default is cured or validly waived in accordance with this Indenture and (y) the 90th day immediately following, and including, the date on which such Reporting Event of Default first occurred; and (ii) if such Reporting Event of Default has not been cured or validly waived prior to the 91st day immediately following, and including the date on which such Reporting Event of Default first occurred, 0.50% per annum of the principal amount of the Notes outstanding for each day during the period beginning on, and including, the 91st day immediately following, and including the date on which such Reporting Event of Default first occurred and ending on the earlier of (x) the date on which such Reporting Event of Default is cured or validly waived and (y) the 180th day immediately following, and including, the date on which such Reporting Event of Default first occurred. For the avoidance of doubt, the 180-day period described in the foregoing sentence will not commence until the expiration of the 60-day period referenced in Section 7.01(a)(vi).

If the Company so elects, the Reporting Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 181st day after such Reporting Event of Default (if the Reporting Event of Default is not cured or waived prior to such 181st day), the Trustee or the Holders of not less than 25% in principal amount of the outstanding Notes may declare the principal of and accrued and unpaid interest on all such Notes to be due and payable immediately (and for the avoidance of doubt, Additional Interest will cease to accrue) as provided above. The provisions described in this paragraph shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. In the event the Company does not elect to pay Additional Interest following a Reporting Event of Default in accordance with this paragraph or the Company elected to make such payment but does not pay such Additional Interest when due, the Notes shall be immediately subject to acceleration as provided above.

If the Company elects to pay the Reporting Additional Interest as the sole remedy during the first 180 calendar days after the occurrence of a Reporting Event of Default, the Company shall notify the Holders, the Trustee and the Paying Agent (if other than the Trustee) of such election prior to the beginning of such 180-day period. Upon the Company’s failure to timely give such notice, the Notes will be immediately subject to acceleration as provided in the first paragraph of Section 7.02(a) above.

Notwithstanding any other provision in this Indenture, in no event shall Additional Interest accrue on any day (taking into consideration any Additional Interest payable as described in Section 3.08(a), Section 3.08(b) or Section 7.02(a)) at a rate in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to the requirement to pay such Additional Interest.

Section 7.03 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if

(a) default is made in the payment of any interest on any Note when such interest becomes due and payable and such default continues for a period of 30 days, or

(b) default is made in the payment of the principal of any Note when due and payable at the Stated Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal and interest, and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and on any overdue interest, at the rate borne by the Notes, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 7.04 Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Notes), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 11.06.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 7.05 Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee,

its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered.

Section 7.06 Application of Money Collected. Subject to Article V, any money or property collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee under Section 11.06;

SECOND: To the payment of the amounts then due and unpaid for principal of and interest on the Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal and interest, respectively; and

THIRD: The balance, if any, to the Company.

Section 7.07 Limitation on Suits. Subject to Section 7.08, no Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

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

(b) the Holders of at least 25% in principal amount of the outstanding Notes shall have made written request to the Trustee to pursue the remedy;

(c) such Holders have offered to the Trustee security or indemnity reasonably satisfactory to it against the loss, liability or expense to be incurred in compliance with such request;

(d) the Trustee has not complied with such request for 60 calendar days after its receipt of such request and offer of security or indemnity; and

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

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all the Holders.

Section 7.08 Right of Holders to Receive Payment. Notwithstanding any other provision in this Indenture, (i) the right of any Holder to receive payment or delivery, as the case may be, of the principal (including the Fundamental Change Repurchase Price, if applicable) of

and accrued and unpaid interest (including Additional Interest, if applicable), if any, on and the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in this Indenture, and the right of any Holder to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates, shall, in each case, not be amended without the consent of such Holder.

Section 7.09 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 7.10 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 7.11 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article VII or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee (subject to the limitations contained in this Indenture) or by the Holders, as the case may be.

Section 7.12 Control by Holders. The Holders of a majority in principal amount of the outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, provided that:

(a) such direction shall not be in conflict with any rule of law or with this Indenture and shall not be unduly prejudicial to the rights of any other Holder or result in personal liability to the Trustee, and

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction or this Indenture;

and provided, further that, if an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of its rights or powers under this Indenture at the request or

direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense.

Section 7.13 Waiver of Past Defaults and Rescission. The Holders of a majority in principal amount of the outstanding Notes may on behalf of the Holders of all the Notes:

(a) waive any past Default or Event of Default hereunder and its consequences, except a Default:

(i) in the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest (including Additional Interest, if any) on any Note that remains uncured, or

(ii) in respect of the failure to deliver amounts due upon conversion of a Note in accordance with Section 5.01, and

(b) at any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article VII provided, rescind and annul any such declaration of acceleration with respect to the Notes and its consequences, 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 nonpayment of the principal of or accrued and unpaid interest (including Additional Interest, if any) on any Note that have become due solely by such declaration of acceleration, have been cured or waived.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 7.14 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant; provided, that this Section 7.14 shall not be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Trustee, to any suit by any Holder or group of Holders holding in the aggregate more than 10% in principal amount of the outstanding Notes or in any suit for the enforcement of the right to exchange any Note in accordance with Article V or for the enforcement of the payment of the principal of or interest on any Note on or after the Maturity of such Note, including the Stated Maturity expressed in such Note.

Section 7.15 Notice of Default. The Company shall deliver to a Responsible Officer of the Trustee, within 30 calendar days after an Officer becomes aware of the occurrence of any events that constitute a Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default, the status of such events and what action the Company is taking or proposing to take with respect thereof.

ARTICLE VIII.
CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

Section 8.01 Company May Consolidate, Etc., Only on Certain Terms. The Company shall not consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to another person, unless:

(i) (x) the Company is the continuing corporation, or (y) the resulting, surviving or transferee Person (if not the Company)(the “Successor Company”) is a corporation organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and such corporation (if not the Company) shall expressly assume, by supplemental indenture hereto, executed and delivered to the Trustee, all obligations of the Company under the Notes and this Indenture; and

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

The Company, or the successor person if other than the Company, shall deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with this Article VIII and that all conditions precedent provided for in the Indenture relating to such transaction have been complied with.

Section 8.02 Successor Substituted. Upon any transaction referred to in Section 8.01 in accordance therewith, the Successor Company shall succeed to, and be substituted for, and may exercise every right and power of the Company under this Indenture with the same effect as if such successor person had been named as the Company herein; and the Company shall be discharged from its obligations under the Notes and this Indenture, except in the case of a lease. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder 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 previously shall have been signed and delivered by an Officer of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under 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. In the event of any such consolidation, merger, sale, transfer or disposition (but not in the case of a lease), upon compliance with this Article VIII, the person named as the “Company” in the first paragraph of this Indenture shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture and the Notes.

ARTICLE IX.
SATISFACTION AND DISCHARGE

Section 9.01 Satisfaction and Discharge of Indenture. The Indenture and the Notes shall upon request of the Company contained in an Officer’s Certificate cease to be of further effect (except as set forth in the last paragraph of this Section 9.01), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture and the Notes, when:

(i) either:

(A) all Notes theretofore authenticated and delivered (other than (x) any Notes that have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.07 and (y) Notes for whose payment money has theretofore been deposited in trust with the Trustee or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or

(B) the Company has deposited with the Paying Agent (if other than the Trustee) or delivered to Holders, as applicable, after all of the outstanding Notes have (X) become due and payable, whether at Maturity or any Fundamental Change Repurchase Date or otherwise, and/or (Y) have been converted (and the related Settlement Amounts have been determined), cash or, solely to satisfy the Company’s Conversion Obligations, cash and/or shares of Common Stock (or if applicable, Reference Property), as applicable, sufficient to pay all of the outstanding Notes and/or satisfy all conversion, as the case may be, and pay all other sums due and payable under the Indenture by the Company; and

(ii) The Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.06 and, if cash or shares of Common Stock shall have been deposited with the Paying Agent pursuant to this Section 9.01(i)(B), Section 2.03 shall survive such satisfaction and discharge.

Section 9.02 Application of Trust Funds. Subject to the provisions of Section 9.03, all money deposited with the Trustee pursuant to Section 9.01, shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the persons entitled thereto, of the principal and interest for whose payment such money has been deposited with or received by the Trustee.

For the avoidance of doubt, this Section 9.02 shall apply to the cash and/or shares of Common Stock deposited with the Trustee pursuant to Section 9.01 and all money or other assets received by the Trustee in respect of shares of Common Stock deposited with the Trustee pursuant to Section 9.01.

All monies deposited with the Trustee pursuant to Section 9.01 (and held by it or any Paying Agent) for the payment of Notes subsequently exchanged shall be returned to the Company upon Company request.

Section 9.03 Repayment to Company. Subject to applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal and interest that remains unclaimed for two years. After that, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

Section 9.04 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money deposited with respect to the Notes in accordance with Section 9.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Indenture with respect to the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 9.01; provided, however, that if the Company has made any payment of principal of or interest on or any additional amounts with respect to any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders to receive such payment from the money held by the Trustee or Paying Agent after payment in full to the Holders.

ARTICLE X.

Section 10.02 With Consent of Holders. Except as provided above in Section 10.01 and below in this Section 10.02, the Company and the Trustee may from time to time and at any time amend or supplement this Indenture and the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the outstanding Notes (including without limitation, consents obtained in connection with a repurchase of, or tender offer or exchange offer for, the Notes), and any existing Default or Event of Default (other than (i) a Default or Event of Default in the payment of the principal (including any Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded, and (ii) a Default or Event of Default as a result of a failure by the Company to deliver the consideration due upon conversion of the Notes) or compliance with any provisions of this Indenture or the Notes may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the outstanding Notes (including without limitation, consents obtained in connection with a repurchase of, or tender offer or exchange offer for, the Notes); provided, however, that, without the consent of each Holder of an outstanding Note affected, no amendment shall:

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

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

(i) make any change in the amendment provisions of this Indenture or the Notes that require each Holder’s consent or in the waiver provisions if such change adversely affects the rights of the Holders.

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 10.06, the Trustee shall join with the Company in the execution of such amendment, supplement or waiver unless such amendment, supplement or waiver adversely affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amendment, supplement or waiver.

It shall not be necessary for any Act or consent of Holders under this Section 10.02 to approve the particular form of any proposed amendment, supplement or waiver of this Indenture, but it shall be sufficient if such Act or consent shall approve the substance thereof.

Section 10.03 Notices of Supplemental Indentures. After any amendment, supplement or waiver under this Article X becomes effective, the Company will send to the Holders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

Section 10.04 Revocation and Effect of Consents; Effect of Amendment, Supplement and Waiver. Until an amendment set forth in a supplemental indenture or a waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Note or subsequent Holder may revoke the consent as to his Note or portion of a Note if the Trustee receives the notice of revocation before the date the supplemental indenture or the date the waiver becomes effective. Upon the execution of any amendment, supplement or waiver of this Indenture pursuant to the provisions of this Article X, this Indenture shall be and be deemed to be modified and amended

in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments and all the terms and conditions of any such amendment or supplement shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 10.05 Notation on or Exchange of Notes. Notes authenticated and delivered after the execution of any amendment, supplement or waiver to this Indenture pursuant to the provisions of this Article X may, at the Company’s expense, bear a notation in form approved by the Trustee as to any matter provided for in such amendment, supplement or waiver. If the Company or the Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any such amendment, supplement or waiver may, at the Company’s expense, be prepared and executed by the Company, authenticated by the Trustee and delivered in exchange for the Notes then outstanding, upon surrender of such Notes then outstanding. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 10.06 Trustee Protected. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 11.01) shall be fully protected in relying upon an Officer’s Certificate or an Opinion of Counsel or both complying with Section 13.06. The Trustee shall sign all supplemental indentures upon delivery of such an Officer’s Certificate or Opinion of Counsel or both, except that the Trustee need not sign any supplemental indenture that adversely affects its rights.

ARTICLE XI.
TRUSTEE

Section 11.01 Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise 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 under the circumstances in the conduct of such person’s own affairs.

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

(i) The Trustee need perform only those duties that are specifically set forth in this Indenture and no others.

(ii) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon Officer’s Certificates or Opinions of Counsel furnished to the Trustee and conforming to the requirements of this Indenture; however, in the case of any such Officer’s Certificates or Opinions of Counsel which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officer’s Certificates and Opinions of Counsel to determine whether or not they conform to the form requirements of this Indenture.

(g) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit.

(i) In no event shall the Trustee be liable to any person for special, punitive, indirect, consequential or incidental loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage.

(l) 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 11.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of the Notes and may otherwise deal with the Company or an Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee is also subject to Section 11.09.

Section 11.04 Trustee’s Disclaimer.

Section 11.05 Notice of Defaults. If a Default or Event of Default occurs and is continuing with respect to the Notes and if written notice of such Default or Event of Default is provided to a Responsible Officer of the Trustee or in the case of an Event of Default under Section 7.01(a)(i) or 7.01(a)(ii) it is actually known to a Responsible Officer of the Trustee, the Trustee shall send to each Holder notice of a Default or Event of Default within 90 calendar days after it occurs or, if later, after a Responsible Officer of the Trustee has written notice or actual knowledge in the case of Events of Default under Section 7.01(a)(i) and 7.01(a)(ii) of such Default or Event of Default. Except in the case of a Default or Event of Default in payment of principal (including the Fundamental Change Repurchase Price, if applicable) or interest on the Notes or a default in the payment or delivery of the consideration due upon conversion, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests of the Holders.

Section 11.06 Compensation and Indemnity.

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 expenses incurred by it. Such expenses shall include the reasonable compensation and expenses of the Trustee’s agents and counsel.

The Company shall indemnify and hold harmless the Trustee (including the cost of defending itself) against any cost, expense (including attorneys’ fees) or liability, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it except as set forth in the next paragraph in the performance of its duties under this Indenture as Trustee or Agent. The Trustee shall notify the Company promptly of any claim by a third party for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, unless and to the extent that the Company is materially prejudiced thereby. Except for claims involving the Company, the Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have one separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent will not

be unreasonably withheld. This indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee.

The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director, employee, shareholder or agent of the Trustee through willful misconduct or gross negligence.

To secure the Company’s payment obligations in this Section 11.06, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on the Notes. Such lien will survive the satisfaction and discharge of this Indenture and the resignation, removal or replacement of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 7.01(ix) or (x) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

The provisions of this Section shall survive the termination of this Indenture and the resignation or removal of the Trustee.

Section 11.07 Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 11.07.

The Trustee may resign with respect to the Notes by so notifying the Company at least 30 days prior to the date of the proposed resignation. The Holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the Trustee and the Company. The Company may remove the Trustee with respect to the Notes if:

(a) the Trustee fails to comply with Section 11.09;

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

If a successor Trustee with respect to the Notes does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least a majority in principal amount of the Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee subject to the lien provided for in Section 11.06, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee with respect to the Notes. A successor Trustee shall mail a notice of its succession to each Holder. Notwithstanding replacement of the Trustee pursuant to this Section 11.07, the Company’s obligations under Section 11.06 hereof shall continue for the benefit of the retiring Trustee with respect to expenses and liabilities incurred by it for actions taken or omitted to be taken in accordance with its rights, powers and duties under this Indenture prior to such replacement.

Section 11.08 Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee, subject to Section 11.09.

Section 11.09 Eligibility; Disqualification. There will at all times be a trustee under this Indenture that is a corporation organized and doing business under the laws of the United States of America or any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of condition.

KKR Real Estate Finance Trust Inc.

6.125% Convertible Senior Notes due 2023

This Note is one of a duly authorized issue of 6.125% Convertible Senior Notes due 2023 (the “Notes”) of the Company, limited to the aggregate principal amount of $[ · ], issued under an indenture, dated as of May 18, 2018 (as amended, modified and supplemented, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Conversion Agent, the Company and the Holders. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. The Notes represent that aggregate principal amount of outstanding Notes from time to time endorsed hereon and the aggregate principal amount of outstanding Notes represented hereby may from time to time be increased or reduced to reflect purchases, cancellations, conversions or transfers permitted by the Indenture.

In case certain Events of Default, as defined in the Indenture, relating to a bankruptcy (or similar proceeding) with respect to the Company shall have occurred, the principal of, and interest on, all Notes shall automatically become immediately due and payable, as set forth in the Indenture. In case any other Event of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal amount on the Stated Maturity, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. Upon conversion of any Note, the Company shall, at its election, pay or deliver, as the case may be, cash, shares of Common Stock or a combination of cash and shares of Common Stock.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

A-7

The Notes are issuable in registered form without coupons in minimum denominations of $1,000 principal amount and integral multiples thereof. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

The Notes are not subject to redemption through the operation of any sinking fund or otherwise.

Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option exercised in the manner specified in the Indenture, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or integral multiples thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the close of business on the second Scheduled Trading Day immediately preceding the Stated Maturity, to convert any Notes or portion thereof that is $1,000 or an integral multiple thereof, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

Terms used in this Note and defined in the Indenture are used herein as therein defined.
