Section 1.05 Acts of Holders. Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action will become effective when such instrument or instruments are delivered to the Trustee and to the Company. Such instrument or instruments

(and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent will be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 1.05.

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution thereof.

The ownership of the Notes shall be proved by the Register.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note will bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, the Company, the Paying Agent, the Conversion Agent or the Registrar in reliance thereon, whether or not notation of such action is made upon such Note.

If the Company will solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company will have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the Close of Business on such record date will be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes will be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date will be deemed effective unless it will become effective pursuant to the provisions of this Indenture not later than six months after the record date.

ARTICLE 2

THE NOTES

Section 2.01 Designation, Amount and Issuance of Notes.

(a) The Notes will be designated as “5.00% Convertible Exchange Senior Notes due 2018.” The aggregate principal amount of Notes that initially may be authenticated and delivered under this Indenture is limited to $85,000,000. From time to time, the Company may

issue and execute, and the Trustee may authenticate, Notes delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.09, 2.11, 2.12, 2.18, 3.06 and 10.02(c) hereof.

The Company at any time or from time to time may, without the consent of any Holder, issue Additional Notes pursuant to Section 2.18, which Additional Notes shall be entitled to all of the benefits of this Indenture. Such Additional Notes will be deemed Notes for all purposes hereunder, including without limitation in determining the necessary Holders who may take the actions or consent to the taking of actions as specified in this Indenture.

Section 2.02 Form of Notes.

(a) General. The Notes will be substantially in the form of Exhibit A hereto, but may include any notations, legends or endorsements required by any applicable law (or regulation promulgated thereunder), stock exchange rule or usage, or any insertions, omissions or other variations otherwise permitted or required by this Indenture. Whenever any such notation, legend or endorsement, or any such insertion, omission or other variation is applicable to a Note, the Company will provide such notation, legend or endorsement, or such insertion, omission or other variation to the Trustee in writing.

Each Note will bear a Trustee’s certificate of authentication substantially in the form set forth in Exhibit A hereto.

Notes that are Global Notes will bear the Global Notes Legend and the “Schedule of Exchanges of Interests in the Global Note” attached thereto.

Notes that are Restricted Notes will bear the Restricted Notes Legend.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent that any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture will govern and control.

(b) Initial and Subsequent Notes. The Notes initially will be issued in global form, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee, at its Corporate Trust Office, as custodian for the Depositary. Except to the extent provided in Section 2.09(c) hereof, all Notes will be represented by one or more Global Notes.

(c) Global Notes. Each Global Note will represent the aggregate principal amount of then outstanding Notes endorsed thereon and provide that it represents such aggregate principal amount of then outstanding Notes, which aggregate principal amount may, from time to time, be reduced or increased to reflect transfers, exchanges, conversions, redemptions or repurchases by the Company.

Only the Trustee, or the custodian holding such Global Note for the Depositary, at the direction of the Trustee, may endorse a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of then outstanding Notes represented thereby, and

whenever the Holder of a Global Note delivers instructions to the Trustee to increase or decrease the aggregate principal amount of then outstanding Notes represented by a Global Note in accordance with Section 2.09 hereof, the Trustee, or the custodian holding such Global Note for the Depositary, at the direction of the Trustee, will endorse such Global Note to reflect such increase or decrease in the aggregate principal amount of then outstanding Notes represented thereby. None of the Trustee, the Company or any agent of the Trustee or the Company will have any responsibility or bear any liability for any aspect of the records relating to, or payments made on account of, the ownership of any beneficial interest in a Global Note or with respect to maintaining, supervising or reviewing any records relating to such beneficial interest.

Neither any member of, or participant in, the Depositary (collectively, the “Agent Members”) nor any other Person on whose behalf an Agent Member may act will have any rights under this Indenture with respect to any Global Note or under such Global Note, and the Company, the Trustee and any agent of the Company or the Trustee, may, for all purposes, treat the Depositary, or its nominee, if any, as the absolute owner and Holder of such Global Note.

The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that Holders are entitled to take under this Indenture or the Notes, and, notwithstanding the foregoing, nothing herein will prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any interest in any Note.

Neither the Trustee nor any of its agents shall have any responsibility or liability for any actions taken or not taken by the Depositary.

Section 2.03 Denomination of Notes. The Notes will be issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples of $1,000 in excess thereof.

Section 2.04 Payments.

Unless earlier paid or deemed paid pursuant to any of Sections 3.05, 10.03 or 11.06 hereof, the Notes will mature on January 1, 2018 (the “Maturity Date”) and, on the Maturity Date, the Company will pay each Holder of Notes $1,000 in cash for each $1,000 principal amount of Notes held, together with accrued and unpaid interest on such Notes to, but not including, the Maturity Date.

(ii) Payment of Interest. Each Note will accrue interest at a rate equal to 5.00% per annum from the date of issuance of such Note or from the most recent date to which interest has been paid or duly provided for, or (x) in the case of the initial Notes issued hereunder on the Issue Date, from April 1, 2015, or (y) in the case of any Notes issued hereunder following the Issue Date in exchange for notes under the Existing Indenture, the Interest Payment Date

immediately prior to the date of issuance for such Notes, subject to the provisions of clause (d) of this Section 2.04, to the date the principal amount of such Note is paid or deemed paid, as the case may be, pursuant to clause (i) of this Section 2.04(a) or any of Sections 3.05, 10.03 or 11.06 hereof.

Interest will be payable semi-annually in arrears in cash on April 1 and October 1 of each year (each, an “Interest Payment Date”), beginning October 1, 2015, to the Holder of each such Note as of the Close of Business on the March 15 or September 15, as the case may be, immediately preceding the applicable Interest Payment Date (each such date, a “Regular Record Date”), regardless of whether such Note is converted, repurchased or redeemed after such Regular Record Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(iii) Method of Payment. The Company will pay the principal of, the Fundamental Change Repurchase Price for, and the interest on, any Global Note to the Depositary by wire transfer of immediately available funds on the relevant payment date.

The Company will pay the principal of, the Fundamental Change Repurchase Price for, and any interest due on the Maturity Date on, any Definitive Note in cash to the applicable Holder of such Note at the office of the Paying Agent on the relevant payment date.

(b) Interest Rights Preserved. Subject to the provisions of Section 2.04(d) hereof, and, to the extent applicable, Sections 2.09 and 2.11 hereof, each Note delivered under this Indenture upon registration of transfer of, or in exchange for, or in lieu of, any other Note will carry any rights to the payment and accrual of interest that were carried by the relevant surrendered Note, Notes, or portion(s) thereof.

(c) Additional Interest; Extension Fee. Pursuant to Section 4.04 hereof, in certain circumstances, Additional Interest may accrue on any Restricted Notes issued after the Issue Date. Pursuant to Section 6.04 hereof, in certain circumstances, the Company may, at its election, be obligated to pay Holders the Extension Fee. Unless the context requires otherwise, all references in this Indenture to interest on the Notes will include such Additional Interest and Extension Fee.

(d) Defaulted Amounts. Any Defaulted Amount will forthwith cease to be payable to the Holder of such Note on the relevant payment date by virtue of its having been due such payment on such payment date, but will accrue interest at the per annum rate borne by the Notes from, and including, such payment date and to, but excluding, the date on which such Defaulted Amount is paid by the Company in accordance with either clause (i) or (ii) below.

(i) The Company may elect to pay any Defaulted Amount 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 Amount (a “Special Record Date”) fixed in accordance with the following procedures:

(A) At least 30 days before the date on which the Company proposes to pay such Defaulted Amounts, the Company will deliver to the Trustee written notice of (I) the proposed payment date for such Defaulted Amounts and (II) the aggregate amount of such Defaulted Amounts.

(B) Simultaneously with delivering such notice to the Trustee, the Company will either (I) deposit with the Trustee an amount of money, in immediately available funds, equal to the aggregate amount of such Defaulted Amounts, or (II) take other actions that the Trustee deems reasonably satisfactory to ensure that an amount of money, in immediately available funds, equal to the aggregate of such Defaulted Amounts will be deposited with the Trustee by 11:00 a.m., New York City time, on the day that is five Business Days prior to the proposed payment date, and in either case, upon receipt of such money, the Trustee will hold such money in trust for the benefit of the Persons entitled to such Defaulted Amounts pursuant to this Section 2.04(d)(i).

(C) Upon (I) receipt of such notice and (II) the Company’s depositing such money or taking such other actions reasonably satisfactory to the Trustee, the Company will promptly fix a Special Record Date for the payment of such Defaulted Amounts, which Special Record Date will be not more than 15 calendar days and not less than 10 calendar days prior to the proposed payment date, and notify the Trustee of the Special Record Date. The Trustee will then, in the name and at the expense of the Company, deliver notice to each Holder specifying such Special Record Date and the date on which such Defaulted Amounts will be paid by the Company.

(D) After such notice has been delivered by the Trustee, such Defaulted Amounts and Default Interest thereon will be paid to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the Close of Business on the Special Record Date specified in such notice and such Defaulted Amounts thereon will no longer be payable pursuant to the following clause (ii) of this Section 2.04(d)(i).

(ii) The Company may pay any Defaulted Amounts in any other lawful manner that is not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes are then listed (or, if applicable, have been listed) or

designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment will be deemed practicable by the Trustee.

Section 2.05 Execution and Authentication.

(a) In General. A Note will be valid only if executed by the Company and authenticated by the Trustee.

(b) Execution. A Note will be deemed to have been executed by the Company when an Officer signs such Note on behalf of the Company. The Officer’s signature may be manual or facsimile, and the validity of such Officer’s signature will not turn on whether such signatory remains an Officer at the time the Trustee authenticates such Note.

(c) Authentication. A Note will be deemed authenticated when an authorized signatory of the Trustee manually signs the certificate of authentication on such Note. An authorized signatory of the Trustee will manually sign the certificate of authentication on a Note only if (i) the Company delivers such Note to the Trustee, (ii) such Note is validly executed by the Company in accordance with Section 2.05(b) hereof, and (iii) the Company delivers, before or with such Note, a Company Order setting forth (A) a request that the Trustee authenticate such Note; (B) the principal amount of such Note; (C) the name of the Holder of such Note; (D) the date on which such Note is to be authenticated; and (E) any insertions, omissions or other variations, notations, legends or endorsements permitted under Section 2.02 hereof and applicable to such Note. If the Company Order also specifies that the Trustee must deliver such Note to the Holder or the Depositary, the Trustee will promptly deliver such Note in accordance with such Company Order.

The Trustee may appoint an authenticating agent. If the Trustee appoints an authenticating agent and such authenticating agent is reasonably acceptable to the Company, such authenticating agent may authenticate a Note whenever the Trustee may authenticate such Note; provided, however, that such authenticating agent may not authenticate any Notes pursuant to Section 2.12 hereof. For purposes of this provision, each reference in this Indenture to authentication by the Trustee will be deemed to include authentication by an authenticating agent, and an authenticating agent will have the same rights to deal with the Company as the Trustee would have if it were performing the duties that the authentication agent was validly appointed to undertake.

Section 2.06 Registrar, Paying Agent and Conversion Agent.

(a) General. The Company will maintain an office or agency in the continental United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”), an office or agency where the Notes may be presented for payment or repurchase (the “Paying Agent”), an office or agency where the Notes may be presented for conversion (the “Conversion Agent”) and an office or agency where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served.

The Registrar will keep a register for the recordation of, and will record, the names and addresses of Holders, the Notes held by each Holder and the transfer, exchange, repurchase,

redemption and conversion of Notes (the “Register”).

The Register will be in written form or in any form capable of being converted into written form within a reasonably prompt period of time.

The Company may have one or more registrars, one or more paying agents, one or more conversion agents and one or more places where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served. Before appointing any Registrar, Paying Agent or Conversion Agent that is not otherwise a party to this agreement, the Company will enter into an appropriate agency agreement with such Registrar, Paying Agent or Conversion Agent, as the case may be, which agency agreement will implement the provisions of this Indenture that relate to such replacement or additional registrar, paying agent or conversion agent, as the case may be. The term Registrar includes any additional registrars named pursuant to this Indenture. The term Paying Agent includes any additional paying agent named pursuant to this Indenture. The term Conversion Agent includes any additional conversion agent named pursuant to this Indenture.

(b) Initial Designations. The Company initially appoints the Trustee as each of the Registrar, the Paying Agent and the Conversion Agent and the Notes initially may be presented for registration of transfer or for exchange, payment, repurchase, redemption and conversion to the Trustee, in its capacity as the Registrar, Paying Agent or Conversion Agent, as the case may be, at the Corporate Trust Office.

(c) Removal, Resignation and Replacement.

The Company may also change the place where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served, or reduce the number of such places; provided, however, that the right to effect any such change or reduction in no way relieves the Company of its obligation to maintain a place in the continental United States where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served.

In addition, the Registrar, Paying Agent or Conversion Agent may resign at any time by delivering written notice of such resignation to each of the Company and the Trustee; provided, however, that if the Trustee is serving as Registrar, Paying Agent or Conversion Agent, the

Trustee may resign from such capacity only if it also resigns as Trustee in accordance with Section 7.07 hereof.

(d) Failure to Maintain an Office or Agency.

In each such case, the Trustee will be entitled to compensation for such action pursuant to Section 7.06 hereof.

Promptly upon the effectiveness of any removal or subsequent appointment of a Registrar, Paying Agent or Conversion Agent, or upon any change in the location of the office of any Registrar, Paying Agent or Conversion Agent, or of the place where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served, the Company will deliver to each Holder notice of such removal, appointment or change in location, as the case may be, which notice will include a brief description of the removal, appointment or change in location, as the case may be, and list the name and address of each continuing (and newly appointed, if applicable) Registrar, Paying Agent and Conversion Agent and place where notices and demands to, or upon, the Company with respect to the Notes and this Indenture may be served.

Section 2.07 Money and Securities Held in Trust. Except as otherwise provided herein, by no later than 11:00 a.m., New York City time, on each due date for a payment on any Note, the Company will deposit with the Paying Agent an amount of money in immediately available funds, if deposited on the due date sufficient to make such payment when due.

The Company will require that each Paying Agent (other than the Trustee, if the Trustee is a Paying Agent) agree in writing that it will (i) segregate all money and securities it holds for making payments with respect to the Notes; (ii) hold such money and securities in trust for the benefit of Holders; and (iii) notify the Trustee, in writing, as promptly as practicable, if the Company defaults in making any payment on the Notes.

If any such Default has occurred and is continuing, the Paying Agent will, upon receiving a written request from the Trustee, forthwith pay to the Trustee all of the money and securities it holds in trust. In addition, at any time, the Company may require a Paying Agent to pay all money and securities that it holds for making payments with respect to the Notes to the Trustee and to account for any money and securities it has disbursed. After delivering all of such money and securities to the Trustee pursuant to this Section 2.07, the Paying Agent will have no further liability for such money and securities.

Section 2.08 Holder Lists. The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders.

If the Trustee is not the Registrar, the Company shall furnish to the Trustee, promptly after each Record Date, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

Section 2.10 Transfer Restrictions.

(a) Prior to the applicable Free Trade Date and at any time the Company reasonably determines that the legend is required to comply with applicable law, any Restricted Notes will bear the Restricted Notes Legend and will be subject to the restrictions set forth therein and will

be deemed to be assigned a Restricted Notes CUSIP. Prior to the applicable Free Trade Date and at any time the Company reasonably determines that the legend is required to comply with applicable law, the shares of Common Stock issuable upon conversion of such Restricted Notes will be issued solely in certificated form and will bear the Restricted Stock Legend and a Restricted Stock CUSIP and be subject to the restrictions set forth therein.

(b) Any Restricted Note (or security issued in exchange or substitution therefor) (i) as to which the applicable Free Trade Date has occurred or such restrictions on transfer shall have otherwise expired in accordance with their terms, (ii) that has been transferred pursuant to a registration statement that has become effective or been declared effective under the Securities Act and that continues to be effective at the time of such transfer or (iii) that has been sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, may, upon surrender of such Restricted Note for exchange to the Registrar in accordance with the provisions of Section 2.09, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restricted Notes Legend required by this Section 2.10 and shall not be assigned a Restricted Notes CUSIP. The Company shall be entitled to instruct the Trustee in writing to so surrender any Global Note as to which any of the conditions set forth in clause (i) through (iii) of the immediately preceding sentence have been satisfied, and, upon such instruction, the Trustee shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the restrictive legend specified in this Section 2.10 and shall not be assigned a Restricted Notes CUSIP.

Section 2.11 Replacement Notes.

If (a)(i) a mutilated Note is surrendered to the Registrar or (ii) the Holder of a Note claims that such Note has been lost, destroyed or stolen and provides the Company and the Trustee with (A) evidence of such loss, theft or destruction that is reasonably satisfactory to the Company and the Trustee and (B) any amount or kind of security or indemnity that either of the Company or the Trustee reasonably request to protect itself from any loss that it may suffer upon replacement of such Note, and, in either case, (b) such Holder satisfies any other reasonable requirements of the Trustee, including the payment of any tax or other governmental charge that may be imposed in connection with the replacement of such Note, then, in either case, unless the Company or the Trustee receives written notice that such Note has been acquired by a bona fide purchaser, the Company will, in accordance with Section 2.05 hereof, promptly execute and deliver to the Trustee, and the Trustee, upon receipt of a Company Order, in accordance with Section 2.05 hereof, will promptly authenticate and deliver, in the name of such Holder, a replacement Note having the same aggregate principal amount as the Note that was mutilated or claimed to be lost, destroyed or stolen, bearing any restrictive legends required by Section 2.10 hereof and with a certificate number not contemporaneously outstanding.

Every new Note issued pursuant to this Section 2.11 in exchange for any mutilated Note, or in lieu of any destroyed, lost or stolen Note, will constitute an original contractual obligation of the Company and any other obligor upon the Notes, regardless of whether the mutilated, destroyed, lost or stolen Note will be at any time enforceable by anyone, and will be entitled to all benefits of (and will be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

Section 2.12 Temporary Notes. Until Definitive Notes are ready for delivery, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee will, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed) (“Temporary Notes”). Temporary Notes will be issuable in any authorized denomination, and substantially in the form of Definitive Notes, but with such omissions, insertions and variations as may be appropriate for Temporary Notes, all as may be determined by the Company. Every such Temporary Note will be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Definitive Notes. Without unreasonable delay the Company will prepare, execute and deliver to the Trustee or such authenticating agent Definitive Notes (other than any Global Note) and thereupon any or all Temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 2.06 hereof and the Trustee or such authenticating agent will authenticate and deliver in exchange for such Temporary Notes Definitive Notes having an aggregate principal amount equal to such Temporary Notes. Such exchange will be made by the Company at its own expense and without any charge therefor. Until so exchanged, the Temporary Notes will, in all respects, be entitled to the same benefits and subject to the same limitations under this Indenture as Definitive Notes authenticated and delivered hereunder.

Section 2.13 Cancellation. At any time, the Company may deliver Notes to the Trustee for cancellation. Whenever any Note is surrendered to the Registrar, Conversion Agent or Paying Agent for registration of transfer, exchange, conversion, repurchase, redemption or payment, the Registrar, Conversion Agent or Paying Agent, as the case may be, will promptly forward such Note to the Trustee. Upon receipt of any such Note, the Trustee, in its customary manner, will promptly cancel and dispose of such Note. The Company may not issue new Notes to replace Notes that it has repurchased, redeemed, paid or delivered to the Trustee for cancellation or that a Holder has converted pursuant to Article 10 hereof.

Section 2.14 Outstanding Notes. At any time, Notes outstanding are limited to all Notes authenticated by the Trustee except (i) those cancelled by it, (ii) those delivered to it for cancellation and (iii) those deemed not outstanding under Sections 3.05, 10.02, 10.12 and 11.06 hereof and clauses (a) and (b) of this Section 2.14.

(a) If a Note is replaced pursuant to Section 2.11 hereof, such Note will cease to be outstanding at the time of its replacement unless the Trustee and the Company receive proof satisfactory to them that such Note is held by a bona fide purchaser.

(b) In addition, if the Company, any other obligor or an Affiliate of the Company or an Affiliate of such other obligor holds a Note, such Note will be disregarded and deemed not to be outstanding for purposes of determining whether the Holders of the requisite aggregate principal amount of Notes have given or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder. Subject to the foregoing, only Notes outstanding at the time of any such determination will be considered in such determination (including determinations pursuant to Articles 6 and 9 hereof).

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 the payment of the principal of, the Fundamental Change Repurchase Price for, and interest, if any, on, such Note, for the purpose of conversion of such Note and for all other purposes whatsoever with respect to such Note, and none of the Company, the Trustee or any agent of the Company or the Trustee will be affected by any notice to the contrary.

Section 2.16 Repurchases. The Company may, from time to time, repurchase Notes in open market purchases or in negotiated transactions without delivering prior notice to Holders. Any Notes that are repurchased or owned by the Company will be submitted to the Trustee for cancellation and will be duly retired by the Company.

Section 2.17 CUSIP and ISIN Numbers.

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

(b) In addition, if, when any shares of Common Stock are issued upon conversion of a Note, CUSIP and ISIN numbers are generally in use, the Company will use CUSIP and ISIN numbers with respect to such shares of Common Stock, which CUSIP and ISIN numbers (i) for shares of Common Stock to which the restrictions on Transfer set forth in the Restricted Stock Legend apply, will be the Restricted Stock CUSIP and the corresponding ISIN, and (ii) for shares of Common Stock to which the restrictions on Transfer set forth in the Restricted Stock Legend do not apply, will be the Unrestricted Stock CUSIP and the corresponding ISIN.

(c) Whenever any of the CUSIP numbers with respect to the Notes or the shares of Common Stock issuable upon conversion of the Notes changes, ceases to be used, or begins to be used, the Company will deliver prompt written notice of such change, cessation, or beginning to each of the Trustee and the Holders.

With respect to any Additional Notes, the Company shall set forth in an Officers’ Certificate, a copy of which shall be delivered to the Trustee, and in a supplemental indenture, the following information:

(1) the aggregate principal amount of Notes outstanding immediately prior to the issuance of such Additional Notes;

(2) all other rights of the Holders of such Notes with respect to such Notes (other than the right to receive payment of the Fundamental Change Repurchase Price upon delivery or transfer of such Notes and any Defaulted Amounts with respect to the Notes) will terminate.

Section 3.06 Notes Repurchased in Part. If any Definitive Note is to be repurchased only in part, the Holder must surrender such Note at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder of such Note or such Holder’s attorney-in-fact, duly authorized in writing), whereupon the Company, in accordance with Section 2.05 hereof, will promptly execute, and, upon receipt of a Company Order, the Trustee, in accordance with Section 2.05 hereof, will promptly authenticate and deliver, to the surrendering Holder, a new Note or Notes of any authorized denomination or denominations requested by such Holder in aggregate principal amount equal to the portion of the principal amount of the Note so surrendered which is not repurchased. If any Global Note is repurchased in part, the Company will instruct the Trustee to decrease the principal amount of such Global Note by the principal amount repurchased.

Section 3.09 Covenant Not to Repurchase Notes upon Certain Events of Default

(a) General. Notwithstanding anything to the contrary in this Article 3, the Company will not purchase any Notes under this Article 3 if, as of the Fundamental Change Repurchase Date, the principal amount of the Notes has been accelerated, such acceleration has not been rescinded and such acceleration did not result from a Default that would be cured by the Company’s payment of the Fundamental Change Repurchase Price.

(b) Deemed Withdrawals.

Section 4.10 Stay, Extension and Usury Laws.

Furthermore, in giving such pro forma effect, interest on any such Indebtedness determined on a fluctuating basis will be deemed to have accrued at a fixed rate per annum equal to the interest rate on the date of determination of Consolidated Fixed Charge Coverage Ratio (after giving effect to any interest rate Swap Contracts applicable to such Indebtedness and any interest rate elections made by the Company or the Subsidiaries).

If any Event of Default (other than an Event of Default specified in Sections 6.01(ix) or 6.01(x) hereof with respect to the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may declare the principal amount of, and all accrued and unpaid interest, if any, on, all then outstanding Notes to be immediately due and payable by delivering written notice to the Company, and upon such declaration, the principal amount of, and all accrued and unpaid interest, if any, on all then outstanding Notes will immediately become due and payable.

(c) Rescission of Acceleration. Notwithstanding anything to the contrary in this Indenture, the Holders of a majority of the aggregate principal amount of the then outstanding Notes may, on behalf of the Holders of all of the then outstanding Notes, rescind any acceleration of the Notes and its consequences hereunder by delivering written notice to the Trustee if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) any and all existing Events of Default, other than the nonpayment of the principal of, the Fundamental Change Repurchase Price for, or any interest on, the Notes that has become due solely as a result of acceleration, have been cured or waived. No such rescission will affect any subsequent Default or impair any right consequent thereto.

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

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

Section 6.04 Sole Remedy for Failure to Report.

(a) General. Notwithstanding anything to the contrary in the Notes or in this Indenture, the Company may elect that the sole remedy for any Event of Default specified in Section 6.01(vi) hereof relating to the Company’s failure to comply with the reporting obligations under Section 4.02 or 4.03 hereof (a “Reporting Event of Default”) will, for the period beginning on the date on which such Reporting Event of Default first occurred and ending on the earlier of (A) the date on which such Reporting Event of Default is cured or validly waived in accordance with Section 6.05 hereof and (B) the 270^th calendar day immediately following the date on which such Reporting Event of Default first occurred, consist exclusively of the right to receive additional interest (the “Extension Fee”) on the Notes at a rate equal to 0.50% per annum on the principal amount of the then outstanding Notes. If the Company elects, the Extension Fee will be payable in the same manner and on the same dates as the stated interest payable on the Notes. The Extension Fee will accrue in addition to any Additional Interest that the Company is obligated to pay under Section 4.04 hereof.

(b) Limitation on Remedy. If (i) a Reporting Event of Default occurs and the Company elects that the sole remedy with respect to such Reporting Event of Default will be the Extension Fee and (ii) on the 271^st day immediately following, and including, the date on which such Reporting Event of Default first occurred, such Reporting Event of Default has not been cured or validly waived in accordance with Section 6.05 hereof, then the Notes will become subject to acceleration under Section 6.02(b) hereof on account of such Reporting Event of Default.

(c) Company Election Notice. To elect to pay the Extension Fee as the sole remedy for a Reporting Event of Default, the Company must deliver written notice of such election to the Holders, the Paying Agent and the Trustee prior to the date on which such Reporting Event of Default first occurs. Any such notice must include a brief description of the report or reports that the Company failed to file that caused such Reporting Event of Default, a statement that the Company is electing to pay the Extension Fee and the date on which such Reporting Event of Default will occur.

If a Reporting Event of Default occurs and the Company fails to timely deliver such notice for such Reporting Event of Default, the Notes will be subject to acceleration under Section 6.02(b) hereof on account of such Reporting Event of Default.

(d) Other Events of Default. Notwithstanding anything to the contrary herein, if the Company elects to pay the Extension Fee with respect to any Reporting Event of Default, the Company’s election will not affect the rights of any Holder with respect to any other Event of Default. For the avoidance of doubt, in no event will the Company be obligated to pay the Extension Fee at a rate greater than 0.50% per annum on the principal amount of then outstanding Notes, regardless of the number of events or circumstances giving rise to requirements to pay such Extension Fee.

Section 6.05 Waiver of Past Defaults. If an Event of Default described in Sections 6.01(i), 6.01(ii), 6.01(iv) or 6.01(vi) (which, in the case of Section 6.01(vi) only, relates to a covenant that cannot be amended without the consent of each affected Holder) or a Default that would lead to such an Event of Default occurs and is continuing, such Event of Default or Default may be waived only with the consent of each affected Holder. Every other Event of Default or Default may be waived by the Holders of a majority of the aggregate principal amount of then outstanding Notes. Whenever any Event of Default is so waived, it will cease to exist, and whenever any Default is so waived, it will be deemed cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any consequent right.

Section 6.06 Control by Majority. At any time, the Holders of a majority of the aggregate principal amount of then outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or for exercising any trust or power conferred on the Trustee with respect to the Notes. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01 hereof, that the Trustee determines to be unduly prejudicial to the rights of any other Holder or that would potentially involve the Trustee in personal liability. Prior to taking any action hereunder,

the Trustee will be entitled to indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such action.

Section 6.07 Limitation on Suits. Except to enforce (i) its rights to receive the principal of, the Fundamental Change Repurchase Price for, interest, if any, on, a Note, or (ii) the failure of the Company to comply with its obligations under Article 10 to convert any Note, no Holder may pursue a remedy with respect to this Indenture or the Notes unless:

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

(b) the Holders of at least 25% of the aggregate principal amount of then outstanding Notes deliver to the Trustee a written request that the Trustee pursue a remedy with respect to such Event of Default;

(c) such Holder or Holders have offered and provided to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or other expense of compliance with such written request;

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

(e) during such 60-day period, the Holders of a majority of the aggregate principal amount of then outstanding Notes did not deliver to the Trustee a direction inconsistent with such written request.

A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder, it being understood that the Trustee does not have any affirmative duty to ascertain whether any usage of this Indenture by a Holder is unduly prejudicial to such other Holders.

Section 6.08 Rights of Holders To Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal of, the Fundamental Change Repurchase Price for, accrued and unpaid interest, if any, on, and any consideration due under Article 10 upon conversion of, its Note, on or after the respective due date, or to bring suit for the enforcement of any such payment and/or delivery on or after the respective due date, will not be impaired or affected without the consent of such Holder and will not be subject to the requirements of Section 6.07 hereof.

Section 6.09 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(i), 6.01(ii) or 6.01(iv) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, the Fundamental Change Repurchase Price for, and interest, if any, on, the Notes, and such further amount as is sufficient to cover the costs and expenses of collection provided for under Section 7.06 hereof.

Section 6.10 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable to have the

claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, will be entitled to collect, receive and distribute any money or other property payable or deliverable on any such claims, and any Custodian 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 consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in any such proceeding, will be denied for any reason, payment of the same will be secured by a lien on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained will be deemed to authorize the Trustee to authorize or consent to, or to accept or to adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.11 Priorities. If the Trustee collects any money or property pursuant to this Article 6, it will pay out the money or property in the following order:

FIRST: to the Trustee, its agents and attorneys for amounts due under Section 7.06 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

SECOND: to the Holders, for any amounts due and unpaid on the principal of, the Fundamental Change Repurchase Price for, accrued and unpaid interest, if any, on, and any cash due upon the conversion of, any Note, without preference or priority of any kind, according to such amounts due and payable on all of the Notes; and

THIRD: the balance, if any, to the Company or to such other party as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.11. If the Trustee so fixes a record date and a payment date, at least 15 days prior to such record date, the Company will deliver to each Holder and the Trustee a written notice, which notice will state such record date, such payment date and the amount of such payment.

Section 6.12 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party

litigant. This Section 6.12 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.08 hereof or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

ARTICLE 7

TRUSTEE

Section 7.01 Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee will exercise the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its 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 undertakes to perform such duties, and only such duties, as are specifically set forth in this Indenture, and no implied covenants or obligations will be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith on its part, as to the truth of the statements and the correctness of the opinions expressed therein, the Trustee may conclusively rely upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture.

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

(i) this paragraph does not limit the effect of Section 7.01(b) hereof;

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

(iii) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Sections 6.06, 12.03 or 12.04 hereof.

(d) Whether herein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to Sections 7.01(a), (b) and (c) hereof.

(e) The Trustee will not be liable for interest on any money received by it hereunder or risk or expend any of its own funds.

(f) Money or shares of Common Stock held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

Section 7.02 Rights of Trustee.

(a) The Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any document, including, but not limited to any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. The Trustee may, however, in its discretion make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee determines to make such further inquiry or investigation, it will be entitled to examine the books, records and premises of the Company, personally or by agent or attorney and at the expense of the Company, and will incur no liability of any kind by reason of such inquiry or investigation.

(b) Before the Trustee acts or refrains from acting, shall be entitled to receive an Officer’s Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in conclusive reliance on the Officer’s Certificate or Opinion of Counsel. Notwithstanding this Section 7.02(b), no Opinion of Counsel will be required in connection with the removal of the Restricted Notes Legend for any Restricted Notes on or after the Free Trade Date with respect to such Restricted Notes.

(c) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys or custodians and will not be responsible for the misconduct or negligence of any agent, attorney or custodian appointed with due care.

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

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

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

(g) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and will be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder, including the Registrar, Paying Agent and Conversion Agent.

(i) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

(j) In no event will the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(k) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

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

(m) Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Notes.

Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. However, if the Trustee acquires any conflicting interest it must eliminate the conflict within 90 days or resign. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with like rights. However, the Trustee must comply with Sections 7.09 and 7.11 hereof.

Section 7.04 Trustee’s Disclaimer. The Trustee will not be responsible for and makes no representation as to the validity, priority or adequacy of this Indenture or the Notes, it will not be accountable for the Company’s use of the proceeds from the Notes, and it will not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication. Neither the Trustee nor any authenticating agent shall be accountable for the use or application by the Company of any Notes of the proceeds thereof.

Section 7.05 Notice of Defaults. If a Default or Event of Default occurs and is continuing and is known to the Trustee, the Trustee will send to each Holder notice of the Default or Event of Default within 90 days after such Default or Event of Default first occurs, or, if it is not known to the Trustee within 90 days, as soon as practicable after it is known to the Trustee; provided, however, that except in the case of a Default or Event of Default that is, or would lead to an Event of Default, described in Section 6.01(i), 6.01(ii) or 6.01(iv) hereof, 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 Holders.

Section 7.06 Compensation and Indemnity

(a) The Company will pay to the Trustee, from time to time, such compensation as will be agreed upon, from time to time, in writing for its services. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee for all reasonable fees and expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses will include the reasonable compensation, fees and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company will fully indemnify the Trustee against any and all loss, liability, claim, damage or expense (including (i) reasonable attorneys’ fees and expenses and (ii) taxes, other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it in connection with the acceptance and administration of this trust and the performance of its duties hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person). The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company of any claim for which it may seek indemnity of which a Trust Officer has actually received written notice will not relieve the Company of its obligations hereunder except to the extent such failure will have materially prejudiced the Company. The Company will defend the claim and the Trustee will cooperate in the defense. If the Trustee is advised by counsel in writing that it may have available to it defenses that are in conflict with the defenses available to the Company, then the Trustee may have separate counsel, and the Company will pay the reasonable fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence, as determined by a final non-appealable decision of a court of competent jurisdiction. The Company need not pay for any settlement made by the Trustee without the Company’s consent, such consent not to be unreasonably withheld. All indemnifications and releases from liability granted hereunder to the Trustee will extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns.

(b) The Company’s payment and indemnity obligations pursuant to this Section 7.06 will survive the resignation or removal of the Trustee and the discharge of this Indenture. If the Trustee incurs expenses after the occurrence of a Default specified in Sections 6.01(ix) or 6.01(x) hereof with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

Section 7.07 Replacement of Trustee.

(a) The Trustee may resign at any time by notifying the Company, in writing, at least 30 days prior to the proposed resignation. The Holders of a majority in aggregate principal amount of then outstanding Notes may remove the Trustee by notifying the Trustee, in writing. The Company may remove the Trustee if:

(i) the Trustee fails to comply with Section 7.09 hereof;

(ii) the Trustee is adjudged bankrupt or insolvent;

(iii) a receiver or other public officer takes charge of the Trustee or its property; or

(iv) the Trustee otherwise becomes incapable of acting.

(b) If the Trustee resigns, is removed by the Company or by the Holders of a majority in aggregate principal amount of the Notes then outstanding, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the “retiring Trustee”), the Company will promptly appoint a successor Trustee.

(c) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders. The retiring Trustee will, upon payment of all of its costs and the costs of its agents and counsel, promptly transfer all property held by it as Trustee to the successor Trustee.

(d) If a successor Trustee 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 10% of the aggregate principal amount of the Notes then outstanding may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee, after written request by any Holder, fails to comply with Section 7.09 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) Notwithstanding the replacement of the Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee.

Section 7.08 Successor Trustee by Merger.

(a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act will be the successor Trustee.

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

Section 7.09 Eligibility; Disqualification. The Trustee will have (or, in the case of a corporation included in a bank holding company system, the related bank holding company will have) a combined capital and surplus of at least $50,000,000, as set forth in its (or its related bank holding company’s) most recent published annual report of condition.

Section 7.10 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action will be taken or such omission will be effective. The Trustee will not be liable to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date will not be less than three Business Days after the date any Officer actually receives such application, unless any such Officer has consented in writing to any earlier date), unless prior to taking any such action (or the effective date in the case of any omission), the Trustee has received written instructions in response to such application specifying the action to be taken or omitted.

ARTICLE 8

SATISFACTION AND DISCHARGE

Section 8.01 Discharge of Liability on Notes. When (a)(i) the Company delivers to the Registrar all outstanding Notes (other than Notes replaced pursuant to Section 2.11 hereof) for cancellation or (ii) all outstanding Notes have become due and payable, whether at the Maturity Date, any Fundamental Change Repurchase Date, or upon conversion or otherwise, and the Company irrevocably deposits with the Trustee or delivers to the Holders, as applicable, cash and/or shares of Common Stock and cash (in lieu of fractional shares of Common Stock) (solely to satisfy amounts due and owing as a result of conversions of the Notes), sufficient to pay all amounts due and owing on all outstanding Notes (other than Notes replaced pursuant to Section 2.11 hereof), (b) the Company pays all other sums payable by it under this Indenture with respect to the then outstanding Notes and (c) the Company delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all of the applicable conditions precedent to the discharge of this Indenture described in this Section have been satisfied, then, subject to Section 7.06 hereof, this Indenture will cease to be of further effect with respect to the Notes and the Holders and the Trustee will acknowledge the satisfaction and discharge of this Indenture with respect to the Notes.

Notwithstanding the satisfaction and discharge of this Indenture, (i) any obligation of the Company to any Holder under Article 10 hereof with respect to the conversion of any Note or to the Trustee under Section 7.06 hereof with respect to compensation or indemnity, and (ii) any

obligation of the Trustee with respect to money deposited with the Trustee under this Article 8 will survive.

After the Trustee and the Paying Agent return such cash and securities, including shares of the Common Stock, to the Company, the Trustee and the Paying Agent will have no further liability to any Holder with respect to such cash and securities, including shares of Common Stock, and any Holder entitled to the payment of such cash or securities, including shares of Common Stock, under the Notes or this Indenture must look to the Company for payment as a general creditor of the Company.

It will not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it will be sufficient if such consent approves the substance of such proposed amendment.

Section 9.03 Execution of Supplemental Indentures. Upon the request of the Company, the Trustee will sign any supplemental indenture authorized pursuant to this Article 9 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee under this Indenture. If the supplemental indenture adversely affects the Trustee’s rights, duties, liabilities or immunities under this Indenture, then the Trustee may, but need not, sign such supplemental indenture. In executing any such supplemental indenture, the Trustee will be provided with, and, subject to the provisions of Section 7.01 hereof, will be fully protected in conclusively relying upon, an Officer’s Certificate and an Opinion of Counsel stating that such supplemental indenture is authorized and permitted under this Indenture and constitutes the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

Section 9.04 Notices of Supplemental Indentures. After an amendment or supplement to this Indenture or the Notes pursuant to Sections 9.01 or 9.02 hereof becomes effective, the Company will promptly deliver written notice to the Trustee, which notice will briefly describe the substance of such amendment or supplement to this Indenture in reasonable detail and state the effective date of such amendment or supplement. The Company, or the Trustee, at the direction of the Company, will then promptly deliver a copy of such notice to each Holder. The failure to deliver such notice to each Holder, or any defect in such notice, will not impair or affect the validity of such amendment or supplement to this Indenture.

Section 9.05 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article 9:

(a) this Indenture will be modified in accordance therewith;

(b) such supplemental indenture will form a part of this Indenture for all purposes; and

Section 9.06 Revocation and Effect of Consents, Waivers and Actions.

(a) Revocation. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder, and every subsequent Holder of a Note or portion 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 Holder, or subsequent Holder, may revoke the consent as to its Note or portion of a Note if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective.

(b) Regular Record Dates. The Company may, but is not obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required, or permitted, to be taken pursuant to this Indenture. If a

record date is fixed, then those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of whether such Persons continue to be Holders after such record date. No such consent will be valid or effective for more than 120 days after such record date.

(c) Binding Effect. After an amendment, supplement or waiver becomes effective, it will bind every applicable Holder. Any amendment or supplement will become effective in accordance with the terms of the supplemental indenture relating thereto, which will become effective upon the execution thereof by the Trustee.

Section 9.07 Notation on, or Exchange of, Notes. If any amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of such Note to deliver such Note to the Trustee. The Trustee may place an appropriate notation on such Note about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company, in exchange for the Note, will issue and the Trustee will authenticate a new Note that reflects the changed terms.

ARTICLE 10

CONVERSIONS

Section 10.01 Right To Convert.

(a) In General. Subject to, and upon compliance with, the provisions of this Article 10, until the Close of Business on the third Business Day immediately preceding the Maturity Date, a Holder may, at its option, convert all of its Notes, or any portion of its Notes having a principal amount equal to $1,000 or an integral multiple of $1,000 in excess thereof, into a number of shares of Common Stock and an amount of cash in lieu of fractional shares of Common Stock, all as determined in accordance with Section 10.03 hereof. Notes may not be converted after the Close of Business on the third Business Day immediately preceding the Maturity Date.

(b) Closed Periods. Notwithstanding anything to the contrary in this Indenture, if a Holder tenders a Fundamental Change Repurchase Notice with respect to its Notes in accordance with Article 3 hereof, such Notes may not be converted except to the extent (A) such Notes are not subject to such Fundamental Change Repurchase Notice; (B) such Fundamental Change Repurchase Notice is withdrawn in accordance with Article 3 hereof; or (C) the Company fails to pay the Fundamental Change Repurchase Price for such Notes in accordance with Section 3.08 hereof.

Section 10.02 Conversion Procedures.

(a) General. To exercise its conversion right with respect to a beneficial interest in a Global Note, the owner of such beneficial interest must (i) comply with the Applicable Procedures for converting such beneficial interest; (ii) pay any funds equal to interest payable between the Conversion Date and the next Interest Payment Date that such Holder is required to pay under clause (d) of this Section 10.02; and (iii) pay any transfer or similar taxes or duties that such Holder is required to pay under the proviso to clause (e) of this Section 10.02.

To exercise its conversion right with respect to a Definitive Note, the Holder of such Note must (i) complete and manually sign the conversion notice on the back of the Note, or a facsimile of such conversion notice (such notice, or such facsimile, the “Conversion Notice”); (ii) deliver such signed and completed Conversion Notice, which is irrevocable, and such Note to the Conversion Agent at its office; (iii) furnish any endorsements and transfer documents that the Company, Conversion Agent, Trustee or Transfer Agent may require; (iv) pay any funds equal to interest payable between the Conversion Date and the next Interest Payment Date that such Holder is required to pay under clause (d) of this Section 10.02; and (v) pay any transfer or similar taxes or duties that such Holder is required to pay under the proviso to clause (e) of this Section 10.02.

The first Business Day on which a Holder satisfies the foregoing requirements with respect to a Note and on which conversion of such Note is not otherwise prohibited under this Indenture will be the “Conversion Date” for such Note.

The conversion of any Note will be deemed to occur at the Close of Business on the Conversion Date for such Note, and any converted Note or portion thereof will cease to be outstanding upon conversion.

(b) Holder of Record. If a Holder surrenders the entire principal amount of a Note for conversion, such Person will no longer be the Holder of such Note as of the Close of Business on the Conversion Date for such Note.

Upon the conversion of a Note, the Person in whose name such shares of Common Stock will be registered will become the holder of record of such shares of Common Stock at the Close of Business on the Conversion Date for such Note.

(c) Conversions in Part. If a Holder surrenders only a portion of the principal amount of a Definitive Note for conversion, promptly after the Conversion Date for such portion, the Company will, in accordance with Section 2.05 hereof, execute and deliver to the Trustee, and the Trustee will, upon receipt of a Company Order, in accordance with Section 2.05 hereof, authenticate and deliver to such Holder a new Definitive Note in an authorized denomination, having a principal amount equal to the aggregate principal amount of the unconverted portion of the Definitive Note surrendered for conversion and bearing registration numbers not contemporaneously outstanding and any restrictive legends that such Definitive Note must bear under Section 2.10 hereof.

Upon the conversion of any beneficial interest in a Global Note, the Conversion Agent will promptly request that the Trustee make a notation on the “Schedule of Increases and Decreases of Global Note” of such Global Note to reduce the principal amount represented by such Global Note by the principal amount of the converted beneficial interest. If all of the beneficial interests in a Global Note are so converted, such Global Note will be deemed surrendered to the Trustee for cancellation, and the Trustee will cause such Global Note to be cancelled in accordance with the Applicable Procedures.

(d) Reimbursement of Interest upon Conversion. If a Holder converts a Note after the Close of Business on a Regular Record Date, but prior to the Open of Business on the Interest

Payment Date corresponding to such Regular Record Date, such Holder must accompany such Note with an amount of cash equal to the amount of interest, if any, that will be payable on such Note from (and including) the Conversion Date until the corresponding Interest Payment Date; provided, however, that a Holder need not make such payment (A) for conversions following the Regular Record Date immediately preceding the Maturity Date; (B) 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 and the Holder converts its Note after the Close of Business on such Regular Record Date and on or prior to the Open of Business on such Interest Payment Date; (C) if the Company has specified a Mandatory Conversion Date that is after a Regular Record Date and on or prior to the Business Day immediately following the Interest Payment Date corresponding to such Regular Record Date; or (D) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

(e) Taxes and Duties. If a Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion; provided, however, that if any tax is due because the converting Holder requested that shares of Common Stock be issued in a name other than its own, such Holder will pay such tax and the Conversion Agent, until having received a sum sufficient to pay such tax, may refuse to deliver any certificates representing the shares of Common Stock being issued in a name other than that of such Holder.

(f) Notices. Whenever a Conversion Date occurs with respect to a Note, the Conversion Agent will, as promptly as possible, and in no event later than the Business Day immediately following such Conversion Date, deliver to the Company and the Trustee notice that a Conversion Date has occurred, which notice will state such Conversion Date, the principal amount of Notes converted on such Conversion Date and the names of the Holders that converted Notes on such Conversion Date.

Section 10.03 Conversion Obligation.

(a) Conversion Obligation. Except as set forth in Sections 10.07 and 10.08 hereof, if a Holder surrenders all or a portion of a Note for conversion, the Company will deliver to such Holder, on the third Business Day immediately following the Conversion Date for such Note, (i) a number of shares of Common Stock equal to the product of (A)(x) the aggregate principal amount of such Note to be converted divided by (y) $1,000 and (B) the Conversion Rate in effect on such Conversion Date, rounded down to the nearest whole number, (ii) an amount of cash equal to the product of (A) the fraction of a share of Common Stock eliminated by such rounding and (B) the Last Reported Sale Price of the Common Stock on such Conversion Date (or if such Conversion Date is not a Trading Day, the immediately preceding Trading Day) and (iii) an amount of cash equal to accrued and unpaid interest to the Conversion Date; unless the Conversion Date occurs during the period after the Close of Business on any Regular Record Date and before the Close of Business on the related Interest Payment Date, in which case interest will be payable on such Interest Payment Date to the Holders in whose names the Notes are registered at the Close of Business on the relevant Regular Record Date.

(b) Conversion of Multiple Notes by a Single Holder. If a Holder converts more than one Note on a single Conversion Date, the number of shares of Common Stock that the Company will deliver to the converting Holder, the amount of cash that the Company will pay to such Holder in lieu of fractional shares of Common Stock and the amount of accrued and unpaid interest, will be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder.

Section 10.04 Common Stock Issued Upon Conversion.

(a) Prior to issuing of any shares of Common Stock under this Article 10, and from time to time thereafter as may be necessary, the Company will reserve out of its authorized but unissued shares of Common Stock a number of shares of Common Stock sufficient to permit the conversion of the Notes.

(b) Any shares of Common Stock delivered upon the conversion of the Notes will be newly issued shares or treasury shares, duly and validly issued, fully paid, nonassessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder or other Person to whom such shares of Common Stock will be delivered). In addition, the Company will endeavor to comply promptly with all federal and state securities laws regulating the offer and delivery of any shares of Common Stock issuable upon conversion of the Notes; provided that the Company will not be obligated to register the offer and sale of such Common Stock under the Securities Act or any other applicable securities laws. The Company will also use commercially reasonable efforts to cause any shares of Common Stock issuable upon conversion of a Note to be listed on whatever stock exchange(s) the Common Stock is listed on the date the converting Holder becomes a record holder of such Common Stock.

(c) If any shares of the Common Stock issued upon conversion will, upon delivery as part of the conversion obligation, be “restricted securities” (within the meaning of Rule 144 or any successor provision in effect at such time), such shares of Common Stock (i) will be issued in physical, certificated form; (ii) will not be held in book-entry form through the facilities of the Depositary; and (iii) will bear any restrictive legends the Company or the Transfer Agent deem necessary to comply with applicable law.

Section 10.05 Adjustment of Conversion Rate. The Company will adjust the Conversion Rate from time to time as described in this Section 10.05, except that the Company will not make an adjustment to the Conversion Rate if each Holder participates (other than in the case of a share split or share 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 the relevant transaction described in this Section 10.05 without having to convert its Notes as if it held a number of shares of the Common Stock equal to the product of (i) the Conversion Rate in effect on the applicable record date, Effective Date or expiration date, and (ii) the aggregate principal amount of Notes held by such Holder (express in thousands) on such date, rounded up to the nearest whole number.

(a) Stock Dividends and Share Splits. If the Company issues shares of Common Stock as a dividend or distribution on shares of the outstanding Common Stock, or if the

Company effects a share split of the Common Stock or a share combination of the Common Stock, the Conversion Rate will be adjusted based on the following formula:

LOGO

Where:


CR₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the record date of such dividend or distribution, or immediately prior to the Open of Business on the Effective Date of such share split or share combination, as applicable;

CR₁	=	the Conversion Rate in effect immediately after the Close of Business on such record date or the Open of Business on such Effective Date;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the Close of Business on such record date or the Open of Business on such Effective Date; and

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

The foregoing adjustment to the Conversion Rate under this clause (a) shall become effective immediately after the Close of Business on the record date for such dividend or distribution or immediately after the Open of Business on the Effective Date of such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 10.05(a) is declared, but not so paid or made, the Conversion Rate will be immediately readjusted, effective as of the date that the Board of Directors 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) Rights, Options and Warrants. If the Company issues to all or substantially all holders of its outstanding Common Stock rights, options or warrants entitling such holders for a period of not more than 60 calendar days after the date of such issuance to subscribe for, or purchase, shares of Common Stock, at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the declaration date of such issuance, the Conversion Rate will be increased based on the following formula:

LOGO

Where:

CR₀

the Conversion Rate in effect immediately prior to the Close of Business on the record date for such issuance;


CR₁	=	the Conversion Rate in effect immediately after the Close of Business on such record date;

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

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

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

Any increase made under this Section 10.05(b) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Close of Business on the record date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, including because the issued rights, options or warrants were not exercised, the Conversion Rate will be immediately decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Rate will be immediately decreased to the Conversion Rate that would then be in effect if the record date for such issuance had not occurred.

For purposes of this Section 10.05(b), in determining whether any rights, options or warrants entitle holders of the Common Stock to subscribe for, or purchase, shares of Common Stock at a price less per share than the average of the Last Reported Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for an issuance, and in determining the aggregate offering price of such shares of Common Stock, there will be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

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

(A) dividends, distributions, rights, options or warrants as to which an adjustment was effected pursuant to Section 10.05(a) hereof or Section 10.05(b) hereof, as applicable;

(B) dividends or distributions paid exclusively in cash for which an adjustment was effected pursuant to Section 10.05(d) hereof;

(D) except as otherwise described below pursuant to which an adjustment is made to the Conversion Rate pursuant to this clause (c), rights issued pursuant to any Company shareholder rights plan then in effect,

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

LOGO

Where:


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

CR₁	=	the Conversion Rate in effect immediately after the Close of Business on such record date;

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

FMV	=	the fair market value (as determined by the Company’s Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets, property or rights, options or warrants to acquire the Company’s Capital Stock or other securities distributed with respect to each outstanding share of Common Stock on the record date for such distribution.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than the “SP₀” (as defined above), in lieu of the foregoing increase, each Holder will receive, for each $1,000 principal amount of Notes held on the record date for the distribution, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets or property, rights, options or warrants to acquire Capital Stock or other securities that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for such distribution.

The foregoing increase made in the Conversion Rate under the portion of this clause (c) above will become effective immediately after the Close of Business on the record 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 will be immediately decreased to

be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(ii) With respect to an adjustment pursuant to this Section 10.05(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate will be increased based on the following formula:

LOGO

Where:


CR₀	=	the Conversion Rate in effect immediately prior to the Close of Business on the last Trading Day of the Valuation Period for such Spin-Off;

CR₁	=	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Valuation Period for such Spin-Off;

FMV₀	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period after, and including, the effective date of the Spin-Off (the “Valuation Period”); and

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

If, however, the Conversion Date for a Note occurs after the record date for a Spin-Off, but on or prior to the first Trading Day of the Valuation Period for such Spin-Off, the Conversion Date will be postponed until the Business Day immediately following such Trading Day (and the definition of “FMV₀” will be modified pursuant to the immediately following proviso); provided, that if the Conversion Date for a Note occurs after the first Trading Day of the Valuation Period for a Spin-Off, but on or before the last Trading Day of such Valuation Period, the reference in the above definition of “FMV₀” to “10” will be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the effective date of such Spin-Off to, but excluding, such Conversion Date.

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

LOGO

Where:


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

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

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

C	=	the amount in cash per share the Company distributes to holders of 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 will receive, for each $1,000 principal amount of Notes held on the record date for such cash dividend or distribution, 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 had owned a number of shares of Common Stock equal to the Conversion Rate in effect on such record date. The foregoing increase in the Conversion Rate made under this clause (d) shall become effective immediately after the Close of Business on the record date for such dividend or distribution. If any such dividend or distribution of the type described in this clause (d) is declared but not so paid or made, the Conversion Rate will be immediately decreased, effective as of the date that the Board of Directors determines not to make or pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(e) Tender Offers or Exchange Offers. If the Company or any of the Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock (other than an odd lot tender offer), to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (such last date, the “Expiration Date”), the Conversion Rate will be increased based on the following formula:

LOGO

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) paid or payable for shares purchased in such tender or exchange offer;

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

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

SP₁	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the Expiration Date.

If, however, the Conversion Date for a Note occurs after the first Trading Day during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the Expiration Date, but on or prior to the last Trading Day of such period, the reference in the above definition of “SP₁” to “10” and the references in the above definitions of “CR₀” and “CR₁” to “10th” will be deemed replaced with references to such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding, such Conversion Date.

(f) Successive Adjustments. After an adjustment to the Conversion Rate under this Article 10, any subsequent event requiring an adjustment under this Article 10 will cause an adjustment to the Conversion Rate as so adjusted, without duplication.

(g) Adjustments Not Yet Effective. If a Holder converts a Note and, as of the Conversion Date for such Note, any distribution or transaction that requires an adjustment to the Conversion Rate pursuant to Sections 10.05(a) through (e) hereof has occurred but has not yet resulted in an adjustment to the applicable Conversion Rate on the Conversion Date and the shares of Common Stock that such Holder will receive upon settlement of its converted Note are not entitled to participate in the relevant distribution or transaction (because they were not held on a related record date or otherwise), then the Company will adjust the number of shares of Common Stock that it delivers to such Holder to reflect the relevant distribution or transaction.

(h) Shareholder Rights Plans. To the extent that the Company’s rights plan is in effect when a Holder converts a Note, the Company will deliver to such Holder, in addition to each share of Common Stock otherwise issuable to such Holder upon conversion of such Note, any rights that, under the rights plan, would be applicable to a share of Common Stock, unless prior to the Conversion Date for such Note, the rights have separated from the Common Stock, in

which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 10.05(c)(i) as if, at the time of such separation, the Company had distributed to all holders of the Common Stock 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 as described in Section 10.05(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

(i) Other Adjustments. Whenever any provision of this Indenture requires the calculation of the Last Reported Sale Price, or a function thereof over a span of multiple days, the Company will make appropriate adjustments to the Last Reported Sale Price or such function thereof to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the record date, Effective Date, Mandatory Conversion Date or expiration date of the event occurs at any time during the period when the Last Reported Sale Prices or functions thereof are to be calculated.

(j) Restrictions on Adjustments. Except as a result of (i) a reverse share split, share combination, or readjustment resulting from dividends or distributions having been declared but not paid or made, (ii) readjustments resulting from distributed rights, options or warrants to the extent that shares of Common Stock have not been delivered after the expiration of such rights, including because the issued rights, options or warrants were not exercised and readjustments where rights options or warrants were not issued, (iii) readjustments resulting from the distribution of Capital Stock, evidences of the Company’s indebtedness or other assets or property of the Company having been declared but not paid, (iv) readjustments resulting from distributions or deemed distributions of contingent rights, options or warrants that were redeemed or repurchased without being exercised prior to their expiration or termination and (v) readjustment from cash dividends or distributions having been declared but not paid or made, in no event will the Conversion Rate be immediately adjusted downward pursuant to Sections 10.05(a), (b), (c), (d) or (e) hereof.

In addition, notwithstanding anything to the contrary elsewhere in this Indenture, the Conversion Rate will 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 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 clause and outstanding as of the Issue Date;

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

(v) for accrued and unpaid interest.

(k) Deferral of Adjustments. The Company may defer any adjustment to the Conversion Rate unless such adjustment would increase the Conversion Rate by at least 1% of the Conversion Rate in effect at the time the Company would otherwise be required to make such adjustment; provided, however, that if the Company defers an adjustment pursuant to this Section 10.05(k), then the Company must carry forward such adjustment and take it into account in any future adjustment. Notwithstanding the foregoing, (i) upon the Conversion Date for any Note, (ii) on the Make-Whole Fundamental Change Effective Date or the Mandatory Conversion Date and (iii) on each annual anniversary of the Issue Date, the Company will give effect to all adjustments that it has otherwise been deferred pursuant to this Section 10.05(k), and those adjustments will no longer be carried forward and taken into account in any future adjustment.

(l) Miscellaneous.

(i) Certain Definitions.

(A) For purposes of this Section 10.05, the number of shares outstanding at any time will include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock, but 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, will not include shares of Common Stock held in the treasury of the Company.

(B) For purposes of this Section 10.05, the term “Effective Date” will mean the first date on which the Common Stock trades on the applicable exchange or in the applicable market, regular way, reflecting the transaction.

(C) For purposes of this Section 10.05, the term “Ex-Dividend Date” will mean the first date on which the shares of the Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question.

Section 10.06 Voluntary Adjustments.

(a) Best Interest Increases. Subject to the limitations of Section 10.06(d) hereof, the Company may, from time to time, to the extent permitted by law, increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is in the best interest of the Company, (ii) such increase is in effect for a period of at least 20 Business Days, and (iii) during such period, such increase is irrevocable.

(b) Tax-Related Increases. Subject to the limitations of Section 10.06(d) hereof and to the extent permitted by law, the Company may (but is not required to) increase the Conversion Rate if the Board of Directors determines that such increase is advisable to avoid, or diminish, any income tax imposed on holders of the Common Stock or rights to purchase the Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) or similar event treated as such for U.S. federal income tax purposes.

(c) Notices. Whenever the Board of Directors determines that the Company will increase the Conversion Rate pursuant to this Section 10.06, the Company will send to each Holder notice of such increase at least 15 Business Days before such increase will take effect,

which notice will state the increase to be made and the period during which such increase will be in effect.

(d) Voluntary Actions. The Company will not take any voluntary action that would result in an adjustment to the Conversion Rate pursuant to Sections 10.05, 10.06 and 10.07 without complying, if applicable, with the stockholder approval rules of The NASDAQ Global Select Market or any similar rule of any stock exchange on which the Common Stock is listed at the relevant time. In accordance with such listing standards, this restriction will apply at any time when the Notes are outstanding, regardless of whether the Company then have a class of securities listed on The NASDAQ Global Select Market.

Section 10.07 Adjustments Upon Certain Fundamental Changes, Certain Conversions or Company Conversion Option.

(a) General. If a Fundamental Change (determined after giving effect to the paragraph immediately following clause (iv) of the definition thereof, but without regard to the exclusion in clause (ii)(B) of the definition thereof) occurs (such event, a “Make-Whole Fundamental Change”), and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company will, in the circumstances described in this Section 10.07, increase the Conversion Rate for such Notes by the number of additional shares of Common Stock (the “Additional Shares”) described in this Section 10.07. For purposes of this Section 10.07, a conversion of Notes will be deemed to be “in connection with” a Make-Whole Fundamental Change if the Conversion Notice for such Notes is received by the Conversion Agent during the period beginning on, and including, the effective date for such Make-Whole Fundamental Change (such date, a “Make-Whole Fundamental Change Effective Date”) and ending on, and including, (A) if such Make-Whole Fundamental Change is also a Fundamental Change, the later of (x) the Close of Business on the third Business Day immediately prior to the related Fundamental Change Repurchase Date and (y) the Close of Business on the 30th Business Day immediately following the date the Company delivers notice to each Holder of such Make-Whole Fundamental Change pursuant to this Section 10.07, and (B) if such Make-Whole Fundamental Change is not a Fundamental Change, the Close of Business on the 30th Business Day immediately following the date the Company delivers notice to each Holder of such Make-Whole Fundamental Change pursuant to this Section 10.07.

In addition, the Conversion Rate applicable to (a) Notes subject to a Company Conversion Option and surrendered for conversion in accordance with Section 10.12 and (b) Notes converted by a Holder in accordance with Section 10.02 on any Conversion Date on which the Last Reported Sale Price of the Common Stock exceeds the Conversion Price, will be increased by a number of Additional Shares as set forth in this Section 10.07.

No later than 5 Business Days after the effective date of a Make-Whole Fundamental Change, the Company will notify the Holders of such effective date and issue a press release announcing such effective date. In the event that any (x) conversion “in connection with” a Make-Whole Fundamental Change, (y) conversion as a result of a Company Conversion Option or (z) conversion on any Conversion Date on which the Last Reported Sale Price of the Common Stock exceeds the Conversion Price, would also be deemed to be any other of the foregoing, a Holder of the Notes to be converted will be entitled to a single increase to the Conversion Rate

with respect to the first to occur of the applicable date of the Make-Whole Fundamental Change Effective Date, the Mandatory Conversion Date and the Conversion Date, respectively, and the later event or events will be deemed not to have occurred for purposes of this Section 10.07.

(b) Determination of Additional Shares. The number of Additional Shares by which the Conversion Rate will be increased if (x) a Holder converts a Note in connection with a Make-Whole Fundamental Change, (y) a Note is converted pursuant to exercise of the Company Conversion Option or (z) a Note is converted by a Holder in accordance with Section 10.02 on any Conversion Date when the Last Reported Sale Price of the Common Stock exceeds the Conversion Price, will be determined by reference to the table below, and will be based on the Stock Price and the Make-Whole Fundamental Change Effective Date, Mandatory Conversion Date or Conversion Date, as applicable.

(c) Adjustment of Stock Prices and Additional Shares. The Stock Prices set forth in the first row (i.e., the column headers) of the table below will be adjusted on each date on which the Conversion Rate must be adjusted pursuant to Section 10.05. The adjusted Stock Prices will equal the Stock Prices in effect immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment, and (ii) the denominator of which is the Conversion Rate in effect immediately after the adjustment. The numbers of Additional Shares set forth in the table below will be adjusted in the same manner, at the same time and for the same events for which the Conversion Rate is adjusted pursuant to Section 10.05 hereof.

(d) Additional Shares Table. The following table sets forth hypothetical Make-Whole Fundamental Change Effective Dates, Mandatory Conversion Dates or Conversion Dates, as applicable, Stock Prices and the number of Additional Shares by which the Conversion Rate will be increased per $1,000 principal amount of Notes for a Holder that converts a Note (i) in connection with a Make-Whole Fundamental Change, (ii) pursuant to exercise of the Company Conversion Option or (iii) in accordance with Section 10.02 when the Last Reported Sale Price of the Common Stock exceeds the Conversion Price.


	Stock Price
Make-Whole Fundamental Change Effective Date / Mandatory Conversion Date / Conversion Date	$3.63		$4.15		$4.63		$5.32		$6.48		$8.00		$10.00		$14.00		$18.00		$22.00

(e) Use of Additional Shares Table. If the Stock Price and/or Make-Whole Fundamental Change Effective Date, Mandatory Conversion Date or Conversion Date, as applicable, for an applicable event are not set forth in the table above, then:

(1) if the Stock Price is between two Stock Prices in the table or the Make-Whole Fundamental Change Effective Date, Mandatory Conversion Date or Conversion Date, as applicable, is between two dates in the table, the number of Additional Shares by which the Conversion Rate will be increased for a Holder that converts a Note will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices listed in the table and the earlier and later dates listed in the table, as applicable, based on a 365-day year;

(2) if the Stock Price is greater than $22.00, subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table, no Additional Shares will be added to the Conversion Rate; and

(3) if the Stock Price is less than $3.63, subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table, no Additional Shares will be added to the Conversion Rate.

Notwithstanding the foregoing, in no event will the Conversion Rate be increased as a result of this Section 10.07 to exceed 275.4821 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment in the same manner, at the same time and for the same events for which the Conversion Rate must be adjusted as set forth in Section 10.05 hereof.

(f) Settlement on Conversion. Except as provided in Section 10.08 hereof, if a Holder converts a Note in connection with a Make-Whole Fundamental Change, the Company will settle such conversion by delivering a number of shares of Common Stock, an amount of cash in lieu of fractional shares of Common Stock and accrued and unpaid interest in accordance with Section 10.03 hereof; provided, however, that notwithstanding anything to the contrary in Section 10.03 hereof, if a Holder converts a Note in connection with a Make-Whole Fundamental Change described in clause (ii) of the definition of Fundamental Change in which the holders of the Common Stock receive only cash in consideration for their shares of Common Stock, the Company will settle such conversion by delivering to such Holder, on the third Business Day immediately following the Conversion Date for such Note, an amount of cash, for each $1,000 principal amount of such Note converted, equal to the product of (i) the Conversion Rate on the Conversion Date applicable to such Note (including any Additional Shares added to such Conversion Rate pursuant to this Section 10.07) and (ii) the Stock Price for such Make-Whole Fundamental Change.

Section 10.08 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.

(a) General. If any of the following events occur:

(1)

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

(2)

any consolidation, merger or combination involving the Company;

(3)

any sale, lease or other transfer to a third party of the consolidated assets of the Company and the Subsidiaries substantially as an entirety; or

(4)

any statutory share exchange;

and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, Capital Stock, other securities, other property or assets (including cash or any combination thereof) (each such event, a “Merger Event,” and, for any Merger Event, the “Reference Property” for such Merger Event), then, at the effective date of such Merger Event, the Company and the resulting, surviving or transferee Person (if other than the Company) of such Merger Event (the “Merger Successor Corporation”) will execute and deliver to the Trustee a supplemental indenture pursuant to Section 9.03 hereof, which supplemental indenture will provide that the right to convert each $1,000 principal amount of Notes into shares of Common Stock and cash in lieu of fractional shares of Common Stock will be changed into the right to convert each $1,000 principal amount of Notes into a number of Units of Reference Property initially equal to the Conversion Rate in effect prior to the effective time of the Merger Event and an amount of cash in lieu of any fractional Unit of Reference Property equal to the product of (A) such fractional Unit of Reference Property and (B) the Last Reported Sale Price of a Unit of Reference Property on the applicable Conversion Date. In addition:

(A) each reference to the “Last Reported Sale Price of the Common Stock” will be deemed to be replaced by a reference to the “Last Reported Sale Price of a Unit of Reference Property”;

(B) if a Unit of Reference Property does not consist solely of one type of common stock that is listed on a U.S. national or regional securities exchange, the adjustments to the Conversion Rate provided in Section 10.05 hereof will be modified as determined by the Board of Directors to provide the Holders with adjustments that have an economic effect on the Holders as nearly equivalent as practicable to the economic effect the adjustments provided by Section 10.05 hereof would have had on the Holders but for such Merger Event.

As promptly as practicable after executing a supplemental indenture in accordance with Section 10.08(a) hereof, the Company will (i) file with the Trustee an Officer’s Certificate briefly describing the reasons therefor, the composition of a Unit of Reference Property for such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent under this Indenture to such Merger Event have been complied with; and (ii) cause to be sent to each Holder, at the address of such Holder as it appears in the register of the Notes maintained by the Registrar, a notice of the execution of such supplemental indenture and the composition of a Unit of Reference Property for such Merger Event; provided, that the failure to deliver such notice to any Holder will not affect the validity or legality of such supplemental indenture.

(b) Successive Merger Events. If more than one Merger Event occurs, this Section 10.08 will apply successively to each Merger Event.

(c) Compliance Covenant. The Company will not become a party to any Merger Event unless its terms are consistent with this Section 10.08.

Section 10.09 [Reserved]

Section 10.10 Notice to Holders Prior to Certain Actions.

(a) In case of any Merger Event then 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 10 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 the 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 the Subsidiaries, (ii) the date on which such Merger Event is expected to become effective or occur, (iii) the Conversion Rate in effect as of the date the Company delivers such notice, (iv) the composition of a Unit of Reference Property for such Merger Event and (v) if applicable, the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event. 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 the Subsidiaries.

(b) Whenever the Company adjusts the Conversion Rate pursuant to Section 10.05, the Company will promptly deliver to each Holder a written notice, which notice will include (i) a brief description of the event requiring adjustment to the Conversion Rate pursuant to Section 10.05, (ii) the effective date of such adjustment, (iii) the Conversion Rate in effect after such adjustment is made and (iv) a schedule explaining, in reasonable detail, how the Company calculated such adjustment. On the same day the Company delivers such notice to each Holder, the Company will deliver to the Trustee, the Paying Agent and the Conversion Agent an Officer’s Certificate that includes all of the information contained in such notice, which Officer’s Certificate each of the Trustee, the Paying Agent and the Conversion Agent may treat as conclusive evidence that the adjustment specified in such Officer’s Certificate is correct and will be in effect as of the effective date specified in such Officer’s Certificate. The failure to deliver such notice will not affect the legality or validity of any such adjustment.

Section 10.11 No Responsibility of Trustee. The Trustee and the Conversion Agent will not have any duty or responsibility to any Holder to determine whether any facts exist that require an adjustment 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 in making the same. Neither the Trustee nor the Conversion Agent will be responsible for any failure of the Company to deliver the number of shares of Common Stock and any amount of cash in lieu of fractional shares of the Common Stock due upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 10. Without limiting the generality of the foregoing, neither the Trustee nor the Conversion Agent will be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 10.08 hereof, including with respect to the calculation of the amount of cash and the number of Units of Reference Property, if any, receivable by Holders upon the conversion of their Notes after any Merger Event, and each, subject to the provisions of Article 7, may accept as conclusive evidence of the correctness of any such provisions, and will be protected in relying upon, the Officer’s Certificate (which the Company will be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

Section 10.12 Company Conversion Option

(a) The Company may elect at its option to cause all or any portion of the Notes to be mandatorily converted in whole or in part (the “Company Conversion Option”) at any time prior to the Close of Business on the Business Day immediately preceding the Maturity Date, if the Last Reported Sale Price of the Common Stock equals or exceeds 115% of the Conversion Price then in effect for at least 20 Trading Days in any 30 Trading Day period (any such period, a “Mandatory Conversion Trigger Period”), ending within five Business Days prior to the Mandatory Conversion Notice Date. For the avoidance of doubt, the Company may exercise its right to cause more than one Company Conversion Option during the term of the Indenture so long as it complies with the other requirements of this Section 10.12.

(b) Notwithstanding the foregoing, the Company may only exercise the Company Conversion Option pursuant to Section 10.12(a) if, as evidenced by an Officer’s Certificate, all of the conditions listed below (the “Equity Conditions”) are satisfied on each day during the period (x) commencing on the date a Mandatory Conversion Notice is delivered to Holders and (y) ending on the Mandatory Conversion Date (the “Equity Conditions Measuring Period”). The Equity Conditions are as follows:

(i) either (1) all shares of Common Stock issuable upon conversion of the Notes and held by a non-Affiliate of the Company shall be eligible for sale without the need for registration under any applicable federal or state securities laws or (2) a shelf registration statement registering the resale of the shares of Common Stock issuable upon conversion of the Notes has been filed by the Company and been declared effective by the SEC or is automatically effective and is available for use, and the Company expects such shelf registration statement to remain effective and available for use from the Mandatory Conversion Notice Date until thirty (30) days following the Mandatory Conversion Date;

(ii) during the Equity Conditions Measuring Period, the Common Stock is listed or traded on The NASDAQ Global Select Market, The NASDAQ Global Market, The NASDAQ Capital Market, The New York Stock Exchange or any of their respective successors (each, an “Eligible Market”) and shall not have been suspended from trading on such Eligible Market (other than suspensions of not more than two Trading Days and occurring prior to the applicable date of determination due to business announcements by the Company) nor shall delisting or suspension by such Eligible Market been threatened or pending either (A) in writing by such exchange or market or (B) by falling below the then effective minimum listing maintenance requirements of such Eligible Market;

(iii) during the Equity Conditions Measuring Period, to the extent any Notes have been delivered to the Company for conversion in accordance with the

terms of the Notes, the Company shall have delivered and paid the number of shares of Common Stock and the amount of cash due upon conversion of the Notes to the Holders in accordance with Section 10.03;

(iv) any applicable shares of Common Stock to be issued upon conversion may be issued in full without violating the rules or regulations of The NASDAQ Global Market or any other applicable Eligible Market on which the Common Stock delivered upon conversion is then listed or trading; and

(v) no Default or Event of Default shall have occurred and be continuing.

(c) In order to exercise the Company Conversion Option pursuant to Section 10.12(a), the Company or, at the written request and expense of the Company, the Trustee on behalf of the Company, shall deliver to each Holder a notice (a “Mandatory Conversion Notice”) of exercise of the Company Conversion Option within five Business Days after the end of the applicable Mandatory Conversion Trigger Period (the date such Mandatory Conversion Notice is sent to the Holders in the manner herein provided, the “Mandatory Conversion Notice Date”). The Company will select the date on which the Notes will be converted pursuant to the Company Conversion Option, which shall be not more than 30 Trading Days but not less than 10 Trading Days after the Mandatory Conversion Notice Date (such date, the “Mandatory Conversion Date”). The Company shall also deliver a copy of such Mandatory Conversion Notice to the Trustee concurrently with the delivery thereof to the Holders to the extent that the Trustee does not deliver such Mandatory Conversion Notice on behalf of the Company. If such Mandatory Conversion Notice is to be given by the Trustee, the Company shall prepare and provide the form and content of such Mandatory Conversion Notice to the Trustee. With respect to Definitive Notes, such delivery shall be by first class mail, and with respect to Global Notes, such delivery shall be pursuant to the Applicable Procedures of the Depositary. The Mandatory Conversion Notice, if sent in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not any Holder receives such Mandatory Conversion Notice.

(d) [Reserved].

(e) The Mandatory Conversion Notice shall state:

(i) the Mandatory Conversion Notice Date;

(ii) the Mandatory Conversion Trigger Period;

(iii) the aggregate principal amount of Notes to be mandatorily converted;

(iv) the CUSIP or similar number or numbers of the Notes being converted;

(v) the Mandatory Conversion Date;

(vi) the Conversion Rate then in effect and the number of Additional Shares by which the Conversion Rate of the converted Notes shall be increased pursuant to Section 10.07(a);

(vii) that on and after the Mandatory Conversion Date interest on the Notes to be converted will cease to accrue; and

(viii) the name and address of each Paying Agent and Conversion Agent and the place or places where such Notes are to be surrendered for conversion.

If fewer than all of the Notes are to be mandatorily converted, the Mandatory Conversion Notice shall identify the Notes to be mandatorily converted (including the certificate number or numbers, if any). In case any Note is to be mandatorily converted in part only, the Mandatory Conversion Notice shall state the portion of the principal amount thereof to be mandatorily converted and shall state that, on and after the Mandatory Conversion Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unconverted portion thereof will be issued.

(f) If the Company opts to mandatorily convert fewer than all of the outstanding Notes, the Trustee shall select the Notes to be mandatorily converted (such that the principal amount of a Holder’s Note not to be converted equals $1,000 or an integral multiple of $1,000 in excess thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate, in all cases in which such Notes are in the form of Global Notes in accordance with the Applicable Procedures. To the extent any Note or portion thereof selected for a Company Conversion Option is submitted for voluntary conversion pursuant to Section 10.02, the portion of such Note submitted for voluntary conversion shall be deemed (so far as may be possible) to be from the portion selected for the Company Conversion Option (with any remaining portion being voluntarily converted pursuant to Section 10.02 hereof); provided, however, for the avoidance of doubt, that the Conversion Rate of any such Note submitted for a voluntary conversion but that is so deemed to be from the portion selected for Company Conversion Option will not be increased by Additional Shares unless on the Conversion Date for any such Note submitted for voluntary conversion the Last Reported Sale Price of the Common Stock exceeds the Conversion Price (in which case the Conversion Rate will be increased by the number of Additional Shares for a Note submitted for voluntary conversion), and such portion will otherwise be voluntarily converted pursuant to Section 10.02 hereof.

(g) Each Holder of a Note, by the Holder’s acceptance thereof, agrees to take the following actions prior to the Mandatory Conversion Date in respect of the portion of its Notes subject to a Company Conversion Option: (i) if a Definitive Note, surrender the mandatorily converted Note, or portion thereof, to the Conversion Agent (or in respect of a Global Note, take any actions required for the surrender of a beneficial interest in such Note pursuant to the Applicable Procedures), (ii) furnish appropriate endorsements and transfer documents if required by the Registrar, the Conversion Agent or the Applicable Procedures, (iii) pay any transfer or other tax, if required by Section 10.02(e), (iv) if the Note is a Global Note, complete and deliver to the Depositary any required instructions

pursuant to the Applicable Procedures and (v) any other action necessary to effectuate the Company Conversion Option as may be reasonably requested by the Company. In the event that a Holder does not take any of the actions set forth in the immediately preceding sentence prior to the Mandatory Conversion Date, each Holder of a Note, by such Holder’s acceptance thereof, authorizes and directs the Company to take any action on such Holder’s behalf to effectuate the Company Conversion Option and appoints the Company such Holder’s attorney-in-fact for any and all such purposes.

Upon presentation of any Note converted in part only, the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unconverted portion of the Note or Notes so presented (subject to the Applicable Procedures in the case of Global Notes).

(h) With respect to any Notes subject to the Company Conversion Option, the Company will deliver to the Holders of such Notes, on the third Business Day immediately following the Mandatory Conversion Date for such Notes, (i) a number of shares of Common Stock equal to the product of (A)(x) the aggregate principal amount of such Notes to be converted divided by (y) $1,000 and (B) the Conversion Rate in effect on such Conversion Date, rounded down to the nearest whole number, (ii) an amount of cash equal to the product of (A) the fraction of a share of Common Stock eliminated by such rounding and (B) the Last Reported Sale Price of the Common Stock on such Conversion Date (or if such Conversion Date is not a Trading Day, the immediately preceding Trading Day) and (iii) an amount of cash equal to accrued and unpaid interest to the Mandatory Conversion Date, unless the Mandatory Conversion Date occurs during the period after the Close of Business on any Regular Record Date and before the Close of Business on the related Interest Payment Date, in which case interest will be payable on such Interest Payment Date to the Holders in whose names the Notes are registered at the Close of Business on the relevant Regular Record Date. Upon the Mandatory Conversion Date, unless the Company defaults in delivering or paying the amounts due pursuant to the foregoing sentence, interest on the Notes or portion of Notes so called for the Company Conversion Option shall cease to accrue and, except as provided in Section 6.08, such Notes shall cease to be entitled to any benefit or security under this Indenture, and the Holders thereof shall have no right in respect of such Notes except the right to receive the shares of Common Stock and cash, if any, to which they are entitled pursuant to this Section 10.12. Upon a conversion pursuant to this Section 10.12, the Person in whose name such shares of Common Stock will be registered will become the holder of record of such shares of Common Stock at the Close of Business on the Mandatory Conversion Date for such Note.

(i) If any of the provisions of this Section 10.12 are inconsistent with applicable law at the time of such Company Conversion Option, such law shall govern.
