(4) “including” means including, without limitation;

(5) words in the singular include the plural, and words in the plural include the singular;

(6) all references to $, dollars, cash payments or money refer to the lawful currency of the United States of America, unless the context requires otherwise;

Section 1.04. 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 shall 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 shall 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 1.04.

(a) 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. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient.

(b) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall 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 or the Conversion Agent in reliance thereon, whether or not notation of such action is made upon such Note.

(c) If the Company shall 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 shall 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 shall 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 shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed to be effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after such record date.

Section 1.05. Form of Documents Delivered to the Trustee. In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to the other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an Officer or Officers of the Company stating that the information with respect to such factual matters is in the possession of

the Company, unless counsel providing such Opinion of Counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

ARTICLE 2

THE NOTES

Section 2.01. Designation and Amount. The Notes shall be designated as the “5.00% Convertible Senior Notes due 2017.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $86,250,000, subject to Section 2.14 and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes hereunder.

Section 2.02. Form and Dating. The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is a part of this Indenture. To the extent applicable, the Company, each of the Subsidiary Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Note shall be dated the date of its authentication. Except as otherwise expressly permitted in this Indenture, all Notes shall be identical in all respects. Notwithstanding any differences among them, all Notes issued under this Indenture shall vote and consent together on all matters as one class.

(a) Initial Notes. The Notes initially shall be issued in the form of one or more Global Notes that shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary and registered in the name of DTC or the nominee thereof (DTC, or any successor thereto, and any such nominee being hereinafter referred to as the “Depositary”), duly executed by the Company and authenticated by the Trustee as hereinafter provided.

(b) Global Notes in General. Each Global Note shall represent the outstanding Notes as shall be specified therein, and each Global Note shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, purchases by the Company and conversions.

Any adjustment of the aggregate principal amount of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof and shall be made on the records of the Trustee and the Depositary. Payment of the principal, accrued and unpaid interest, if any, or payment of the Fundamental Change

Purchase Price on the Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is provided for herein.

(c) Book-Entry Provisions. This Section 2.02(c) shall apply only to Global Notes deposited with or on behalf of the Depositary. The Company shall execute, and the Trustee shall, in accordance with Section 2.03, authenticate and deliver, Global Notes that shall be (i) registered in the name of the Depository or the nominee of the Depositary and (ii) delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions.

(d) Legends.

(i) Each Global Note shall bear the Global Securities Legend set forth in Exhibit A unless otherwise directed by the Company.

(ii) Each Restricted Note shall bear the Restricted Securities Legend set forth in Exhibit A. Each Note that bears or is required to bear the Restricted Securities Legend shall be subject to the restrictions on transfer set forth therein, and each Holder of such Note, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer.

(iii) Every stock certificate representing the shares of Common Stock, if any, issued in the circumstances described in Section 2.06(f) hereof shall bear the Restricted Stock Legend set forth in Exhibit B unless removed in accordance with the provisions of Section 2.06(i) or otherwise at the direction of the Company.

Section 2.03. Execution and Authentication. The Notes shall be executed on behalf of the Company by any Officer. The signature of the Officer on the Notes may be manual or facsimile.

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

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

A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

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

The Trustee may appoint authenticating agents. The Trustee may at any time after the Issue Date appoint an authenticating agent reasonably acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so, except

any Notes issued pursuant to Section 2.07 hereof. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same right to deal with the Company as the Trustee with respect to such matters for which it has been appointed.

Section 2.04. Registrar, Paying Agent and Conversion Agent. The Company shall maintain in the Borough of Manhattan, New York City an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”), an office or agency in where Notes may be presented for payment (“Paying Agent”), an office or agency where Notes may be surrendered for conversion (“Conversion Agent”) and an office or agency where notices to or upon the Company in respect of the Notes and this Indenture may be served. The Registrar shall keep a register for the recordation of, and shall record, the names and addresses of Holders of the Notes, the Notes held by each Holder and the transfer, exchange and conversion of Notes (the “Register”). The entries in the Register shall be conclusive, and the parties may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Holder hereunder for all purposes of this Indenture. The Company may have one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term Paying Agent includes any such additional paying agents. The term Conversion Agent includes any such additional conversion agents.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent, Conversion Agent or co-registrar not a party to this Indenture, which (i) shall implement the provisions of this Indenture relating to such agent and (ii) in the case of the Paying Agent, shall include the provisions set forth in Section 5.05. The Company shall promptly notify the Trustee of the name and address of any such agent, and of any change therein. If the Company fails to maintain any of a Registrar, Paying Agent or Conversion Agent, any presentations, surrenders, notices and demands required to be made by, or at the office of, any such agent may be made or served at the Corporate Trust Office or in accordance with Section 15.01; provided that the Trustee shall be entitled to appropriate compensation therefor pursuant to Section 8.06. The Company may act as Paying Agent, Registrar, Conversion Agent or co-registrar.

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

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

Section 2.06. Transfer and Exchange.

(a) Subject to Section 2.12 hereof, upon surrender for registration of transfer of any Note, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Holder or such Holder’s attorney-in-fact duly authorized in writing, at the office or agency of the Company-designated Registrar or co-Registrar pursuant to Section 2.04, (i) the Company shall execute, and the Trustee (or any authenticating agent) shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations, of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture and (ii) the Registrar shall record the information required pursuant to Section 2.04 regarding the designated transferee or transferees in the Register. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co- Registrar or the Paying Agent for any registration of transfer or exchange of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer taxes or governmental charges required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for registration of transfer or exchange.

At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations, of a like aggregate principal amount, upon surrender of the Notes to be exchanged, at such office or agency, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Holder or such Holder’s attorney-in-fact duly authorized in writing, and documents of identity and title satisfactory to Registrar. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

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

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

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

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

(e) Transfer Restrictions.

(i) Every Note that bears or is required under this Section 2.06(e) to bear the Restricted Securities Legend required by Section 2.02(d) (the “Restricted Notes”) shall be subject to the restrictions on transfer set forth in this Section 2.06(e) and such legend unless such restrictions on transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Note, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. If a request is made to remove the Restricted Securities Legend from any Restricted Note prior to the Resale Restriction Termination Date, the legend shall not be removed unless there is delivered to the Company and the Registrar such certificates, legal opinions and other information as they may reasonable require confirming that such Notes, upon such transfer, will not be “restricted” within the meaning of Rule 144. In such a case, upon (A) provision of such certificates, legal opinions and/or other information, or (B) notification by the Company to the Trustee and Registrar of the sale of such Note pursuant to a registration statement that is effective at the time of such sale, the Trustee, pursuant to a Company Order, shall authenticate and deliver a Note that does not bear the Restricted Securities Legend.

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

(iii) No transfer of any Restricted Note will be registered by the Registrar unless the applicable box on the Form of Assignment and Transfer has been checked.

(f) Legends on the Common Stock. Except as provided elsewhere in this Indenture (including, without limitation, Section 2.06(i) below), until the Resale Restriction Termination Date, any stock certificate representing shares of Common Stock issued upon conversion of any Notes shall bear the Restricted Stock Legend unless (I) such Notes or such Common Stock, as applicable, has been resold or otherwise transferred (i) under a registration statement that has been declared effective under the Securities Act; or (ii) in accordance with Rule 144 under the Securities Act or (II) such requirement is waived by the Company.

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

(h) Any Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for exchange to the Registrar in accordance with the provisions of this Section 2.06, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restricted Securities Legend and shall not be assigned a restricted CUSIP number. The Company shall be entitled to instruct the custodian for the Depositary (or its nominee) in writing to so surrender any Global Note as to which such restrictions on transfer shall have expired in accordance with their terms for exchange, and, upon such instruction, such custodian shall so surrender such Global Note for exchange; and any new Global Note so exchanged therefor shall not bear the Restricted Securities Legend and shall not be assigned a restricted CUSIP number. The Company shall promptly notify the Trustee upon the occurrence of the Scheduled Free Trade Date and promptly after a registration statement, if any, with respect to the Notes or any Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act.

(i) The Company shall use its commercially reasonable efforts to cause the removal, no later than the Scheduled Free Trade Date, of any Restricted Stock Legend from any shares of its Common Stock delivered upon conversion on or prior to the Scheduled Free Trade Date. Upon the removal of such Restricted Stock Legend, the Company shall also (i) notify the holders of any such shares that such Restricted Stock Legend has been removed; (ii) notify the transfer agent for the Common Stock to change the CUSIP number for any such shares to the applicable unrestricted CUSIP number, if such shares are in certificated form, and (iii) if such shares are in global form, comply with Applicable Procedures regarding such de-legending and the change from a restricted to an unrestricted CUSIP number. Any shares of Common Stock (x) delivered upon the conversion of any Note to any Person that is not an Affiliate of the Company (and has not been an Affiliate of the Company at any time during the immediately preceding three months) following the Scheduled Free Trade Date or (y) delivered upon conversion of a Note that does not, or would not be required hereunder to, bear the Restricted Securities Legend, in each case, shall be issued without any Restricted Stock Legend. Notwithstanding anything in this Indenture or the Notes to the contrary, any Person, other than an Affiliate of the Company (or a Person that has been an Affiliate of the Company at any time during the immediately preceding three months), who holds shares of Common Stock that were issued upon conversion shall have the right to enforce this Section 2.06(i) notwithstanding that such Person is not a Holder of Notes.

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

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

Notwithstanding the foregoing, with respect to any Global Note, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Global Note or shall impair, as between such Depositary and owners of beneficial interests in such Global Note, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Note.

Section 2.07. Replacement Notes. If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that such Note has been lost, destroyed or stolen and the Holder provides evidence of the loss, theft or destruction reasonably satisfactory to the Company and the Trustee, the Company shall issue, and the Trustee shall authenticate, a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond reasonably sufficient to the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss that any of them may suffer if a Note is replaced. The Company and the Trustee shall not charge the Holder for their expenses in replacing a Note; provided that upon the issuance of any new Notes under this Section 2.07, the Company may require the payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer taxes or

governmental charges that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith as a result of the name of the Holder of replacement Notes issued upon such issuance or being different from the name of the Holder of the mutilated Notes surrendered for replacement.

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

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

Section 2.08. Outstanding Notes. Notes outstanding at any time include and are limited to all Notes authenticated by the Trustee except (a) Notes cancelled by the Trustee or required to be delivered to the Trustee for cancellation in accordance with Section 2.10, (b) Notes, or portions thereof, the principal of which has become due and payable on the Maturity Date, on a Fundamental Change Purchase Date or otherwise, and in respect of which monies in the necessary amount shall have been deposited in trust with the Trustee or with any Paying Agent (other than the Company) or shall have been set aside and segregated in trust by the Company (if the Company shall act as its own Paying Agent), (d) Notes, or portions thereof, that have been converted pursuant to Article 11 and that are required to be cancelled pursuant to Section 2.10 and (e) Notes repurchased by the Company, directly or indirectly, whether by the Company or its Subsidiaries, pursuant to Section 2.14 (other than Notes repurchased pursuant to cash-settled swaps or other derivatives). For the purpose of determining whether the Holders of the requisite principal amount of Notes have given or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder (including, without limitation, determinations pursuant to Articles 7 and 10), only outstanding Notes shall be considered in any such determination. In addition, for the purpose of any such determination, Notes that are owned by the Company, by any Subsidiary thereof or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Subsidiary thereof shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action, only Notes that a Trust Officer knows are so owned shall be so disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding for the purposes of this Section 2.08 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the Company, a Subsidiary thereof or a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or a Subsidiary thereof. In the case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 8.01, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Section 2.09. Temporary Notes. Until Certificated Notes are ready for delivery, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed) (“Temporary Notes”). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of Certificated Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be reasonably determined by the Company. Every such Temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Certificated Notes. As promptly as reasonably possible, the Company will prepare, execute and deliver to the Trustee or such authenticating agent Certificated Notes (other than any Global Note) and thereupon any or all Temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 2.04 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such Temporary Notes an equal aggregate principal amount of Certificated Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the Temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Certificated Notes authenticated and delivered hereunder.

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

Section 2.11. Persons Deemed Owners. Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving payment of principal, interest, if any, or payment of the Fundamental Change Purchase Price, for the purpose of conversion and for all other purposes whatsoever, subject to Section 2.06(i), Section 2.08 and Section 2.12(a)(ii), whether or not such Note be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12. Transfer of Notes.

(a) Notwithstanding any other provisions of this Indenture or the Notes, (A) transfers of a Global Note, in whole or in part, shall be made only in accordance with Sections 2.06 and

2.12(a)(i); and (B) transfers of a beneficial interest in a Global Note for a Certificated Note shall comply with Sections 2.06 and 2.12(a)(ii). All such transfers shall comply with the Applicable Procedures to the extent so required.

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

(ii) Restrictions on Transfer of a Beneficial Interest in a Global Note for a Certificated Note.

(A) A Certificated Note will be issued and delivered:

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

(2) if an Event of Default has occurred and is continuing, to each beneficial owner that DTC identifies who requests that its beneficial interests in the Notes be exchanged for Certificated Notes (in accordance with the Applicable Procedures).

Notwithstanding anything to the contrary in this Indenture or in the Notes, following the occurrence and during the continuance of an Event of Default, any beneficial owner of a Global Note may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such beneficial owner’s right to exchange its beneficial interest in such Global Note for a Certificated Note in accordance with this Section 2.12(a)(ii).

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

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

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

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

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

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

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

Section 2.13. CUSIP, ISIN and Other Similar Numbers.

(a) The Company, in issuing the Notes, shall use restricted CUSIP, ISIN and other similar numbers for such Notes (if then generally in use) until such time as the Restricted Securities Legend is removed therefrom. At such time as the legend is removed from such Notes, the Company will use an unrestricted CUSIP number for such Note, but only with respect to the Notes from which the legend has been so removed. The Trustee may use CUSIP, ISIN and other similar numbers in notices as a convenience to Holders; provided, however, that neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP, ISIN or

other similar numbers that appears on any Note, check, advice of payment or notice, and any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Notes, and any action taken in connection with such a notice shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in the event of any change in the CUSIP, ISIN or other similar numbers.

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

Section 2.14. Additional Notes; Repurchases. The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes under this Indenture with the same terms as the Notes initially issued hereunder, except for any differences in the issue price and interest accrued, if any, prior to the issue date of such additional Notes, in an unlimited aggregate principal amount; provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. The Notes initially issued hereunder and any such additional Notes shall be treated as a single class for all purposes under this Indenture and shall vote together as one class on all matters with respect to the Notes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 15.03, as the Trustee shall reasonably request. The Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives.

Section 3.04. Effect of Fundamental Change Purchase Notice.

(a) If a Holder validly delivers to the Paying Agent a Fundamental Change Purchase Notice (together with all necessary endorsements) with respect to a Note, such Holder may no longer convert such Note unless and until such Holder validly withdraws such Fundamental Change Purchase Notice in accordance with Section 3.03(c) above.

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

(ii) all other rights of the Holders with respect to the surrendered Notes shall terminate (other than the right to receive payment of the Fundamental Change Purchase Price and previously accrued and unpaid interest, if any, upon delivery or transfer of the Notes).

Section 3.05. Deposit of Fundamental Change Purchase Price. Prior to 11:00 a.m., New York City time, on the Fundamental Change Purchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 5.05(b)) an amount of cash (in immediately available funds if deposited on such Business Day), sufficient to pay the aggregate Fundamental Change Purchase Price of all the Notes or portions thereof which are to be purchased as of the Fundamental Change Purchase Date. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for purchase (and not withdrawn prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date) will be made on the later of (i) the Fundamental Change Purchase Date (provided the Holder has satisfied the conditions in Section 3.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 3.01 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

To the extent that the aggregate amount of cash deposited by the Company with the Paying Agent pursuant to Section 3.05 exceeds the aggregate Fundamental Change Purchase Price of the Notes or portions thereof which the Company is obligated to purchase as of the Fundamental Change Purchase Date, then, unless otherwise agreed in writing with the Company, promptly after the Business Day following the Fundamental Change Purchase Date, the Paying Agent shall return any such excess to the Company.

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

(a) Notwithstanding anything to the contrary in this Article 3, no Notes may be purchased by the Company at the option of the Holders on any Fundamental Change Purchase Date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such Fundamental Change Purchase Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Fundamental Change Purchase Price with respect to such Notes).

(b) If a Fundamental Change Purchase Notice is delivered and, on the Fundamental Change Purchase Date, such Fundamental Change Purchase Notice has not been validly withdrawn in accordance with Section 3.03(c) above, and, pursuant to this Section 3.09, the Company is not permitted to purchase Notes, the Paying Agent will deem to be withdrawn such Fundamental Change Purchase Notice.

(c) If a Holder surrenders a Note for purchase pursuant to this Article 3 and, on the Fundamental Change Purchase Date, pursuant to this Section 3.09, the Company is not permitted to purchase such Note, the Paying Agent will (i) if such Note is a Certificated Note, return such Note to such Holder, and (ii) if such Note is held in book-entry form, in compliance with the Applicable Procedures, deem to be cancelled any instructions for book-entry transfer of such Note.

Such Officer’s Certificate shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the Trustee (or, if the Trustee is not the Paying Agent, the Paying Agent) to make payment to the extent it receives funds from the Company to do so. Unless and until the Trustee receives such an Officer’s Certificate, subject to Article 8, the Trustee may assume without inquiry that no such Additional Interest is payable.

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

(a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 5.05:

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

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

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

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

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

(c) Notwithstanding anything in this Section 5.05 to the contrary, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 5.05, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal (including the Fundamental Change Purchase Price, if applicable) of, and accrued and unpaid interest on, any Note and remaining unclaimed for two years after such principal (including the Fundamental Change Purchase Price, if applicable) or interest has become due and payable shall be paid to the Company on request of the Company contained in an Officer’s Certificate, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such

Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, New York City, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 5.06. Delivery of Certain Information. So long as any of the Notes or any shares of Common Stock issuable upon conversion thereof will, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Company (and, in the case of the Notes, the Subsidiary Guarantors) shall, upon the request of any Holder, beneficial owner or prospective purchaser of the Notes or any shares of Common Stock issuable upon conversion of the Notes, promptly furnish such Holder, beneficial owner or prospective purchaser the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of the Notes or such shares of Common Stock pursuant to Rule 144A.

The Company will not consolidate with, merge with or into or enter into any similar transaction with, or sell, convey, transfer, lease or otherwise dispose of all or substantially all of its property and assets to, any Person, unless:

(a) the resulting, surviving or transferee Person (the “Successor Company”) is a corporation organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia, and such Successor Company (if other than the Company) expressly assumes, by executing and delivering to the Trustee a supplemental indenture, all of the Company’s obligations under the Notes and under this Indenture;

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

(d) the Company and the Successor Company (if other than the Company) shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that:

For purposes of this Section 6.01, any sale, conveyance, transfer, lease or other disposition of properties and assets of one or more Subsidiaries of the Company that would, if the Company had held such properties and assets directly, have constituted the sale, conveyance, transfer, lease or other disposition of substantially all of the Company’s properties and assets shall be treated as such hereunder.

Section 6.02. Successor Corporation to be Substituted. Upon any such consolidation, merger (or similar transaction), sale, conveyance, transfer or other disposition (but not upon a lease) and the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of (including the Fundamental Change Purchase Price, if applicable), accrued and unpaid interest, if any, on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Company, such Successor Company shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue in its own name, any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. Upon any such consolidation, merger (or similar transaction), sale, conveyance, transfer or other disposition (but not upon a lease), the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 6 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under this Indenture.

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

(ix) any Subsidiary Guarantee ceases to be in full force and effect, other than in accordance with the terms of this Indenture, or a Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee;

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

(xi) an involuntary case or other proceeding shall be commenced against the Company or any then-current Significant Subsidiary thereof seeking liquidation, reorganization or other relief with respect to the Company or such Significant Subsidiary or its debts under any bankruptcy, insolvency or other similar law now or hereafter in

(b) Within the 30 days immediately following the occurrence of an Event of Default or any Default, the Company shall deliver to a Trust Officer of the Trustee at its Corporate Trustee Office, in accordance with Section 15.01, written notice thereof in the form of an Officer’s Certificate describing each Event of Default or Default that has occurred and is continuing and its status and explaining what action the Company is taking or proposes to take in respect thereof, which notice shall make explicit reference to this Indenture, the Notes and the Company.

(c) Notwithstanding anything to the contrary in the Notes or elsewhere in this Indenture, at the election of the Company, the sole remedy of Holders for an Event of Default relating to the failure by the Company to comply with its obligation to file reports, information or documents with the Trustee pursuant to Section 5.02(a) (the “Company’s Filing Obligations”) shall, for the first 180 days after the occurrence of such Event of Default, consist exclusively of the right to receive Additional Interest at a rate equal to:

(i) 0.25% per annum on the principal amount of the Notes then outstanding for each day during the period beginning on, and including, the date on which such an Event of Default first occurs and ending on the earlier of (A) the date on which such Event of Default is cured or validly waived and (B) the 90th day immediately following the date on which such Event of Default first occurred; and

(ii) if such Event of Default has not been cured or validly waived prior to the 91st day immediately following the date on which such Event of Default first occurred, 0.50% per annum on the principal amount of the Notes then outstanding for each day during the period beginning on, and including, the 91st day immediately following the date on which such an Event of Default first occurs and ending on the earlier of (A) the date on which such Event of Default is cured or validly waived and (B) the 180th day immediately following the date on which such Event of Default first occurs.

If the Company makes such election to pay Additional Interest, such Additional Interest shall be payable in arrears on each Interest Payment Date following the date on which such Event of Default first occurs in the same manner as the stated interest payable on the Notes. Such Additional Interest shall be in addition to, and not in lieu of, any Additional Interest that the Company is required to pay under Section 5.02(b) or (c). On the 181st day following the date on which such Event of Default first occurs (if such Event of Default is not cured or waived prior to such 181st day), the Notes shall be subject to acceleration as provided in Section 7.02. The provisions contained in this Section 7.01(c) shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. If the Company does not elect to pay Additional Interest upon an Event of Default in accordance with this Section 7.01(c), the Notes shall be subject to acceleration as provided in Section 7.02. In order to elect to pay Additional Interest as the sole remedy for the first 180 days after the occurrence of an Event of Default relating to the failure by the Company to comply with the Company’s Filing Obligations, the Company must notify, in the manner provided for in Section 15.01, the Trustee, the Paying Agent (if other than

the Trustee) and all Holders of Notes of such election at any time on or before the Close of Business on the Business Day immediately following the date on which such Event of Default first occurs (which notice shall include a statement as to the date from which Additional Interest is payable and, in the case of the Trustee, shall be delivered to its Corporate Trust Office and shall make explicit reference to this Indenture, the Notes and the Company). Unless and until a Trust Officer receives at the Corporate Trust Office such notice, the Trustee may assume without inquiry that no Additional Interest is payable. Upon failure by the Company to timely give such notice to pay such Additional Interest, or if the Company has given such notice but has failed to pay such Additional Interest, the Notes shall be immediately subject to acceleration as provided in Section 7.02. If Additional Interest has been paid by the Company directly to the Persons entitled to it, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment.

Section 7.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 7.01(a)(x) or 7.01(a)(xi) with respect to the Company) occurs and is continuing, and in each and every such case, except with respect to any Notes the principal of which shall have already become due and payable, either the Trustee, by notice to the Company, or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding, by notice to the Company and to the Trustee, may, and the Trustee at the request of such Holders (provided that the Trustee may require from such Holders indemnity or security reasonably satisfactory to it against any loss, liability or expense caused by taking such action) shall, declare 100% of the principal amount of, and accrued and unpaid interest on, all of the Notes then outstanding, to be due and payable immediately, and upon any such declaration the same shall be and become immediately due and payable. If an Event of Default specified in Section 7.01(a)(x) or 7.01(a)(xi) occurs with respect to the Company, then 100% of the principal amount of, and all accrued and unpaid interest on, all of the Notes then outstanding shall be and become immediately due and payable, automatically and without any notice or other action by any Holder or the Trustee, to the fullest extent permitted by applicable law. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by written notice to the Trustee and the Company and without notice to any other Holder, may rescind any acceleration of the Notes in accordance with Section 7.04.

Section 7.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

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

Section 7.04. Waiver of Past Defaults; Rescission of Acceleration. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by written notice to the Trustee and the Company and without notice to any other Holder, may waive any Default (except with respect to (a) any failure by the Company to pay the principal of or accrued interest

on the Notes (including the Fundamental Change Purchase Price, if applicable), (b) any failure by the Company to comply with its obligations to purchase Notes when required to do so under Article 3, and any failure by the Company to deliver any consideration due upon conversion of the Notes, or (c) any default by the Company in respect of any covenant or provision of this Indenture or the Notes that under Section 10.02 cannot be modified or amended without the consent of each Holder) and may rescind any acceleration of the Notes if (i) such waiver and rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the principal of and interest on the Notes that has become due solely by such acceleration, have been cured or waived. Any such waiver or rescission shall not affect any subsequent or other Default or impair any right consequent thereon.

Section 7.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided that (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or would involve the Trustee in personal liability and (ii) for the avoidance of doubt, the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Subject to Article 8, if an Event of Default has occurred and is continuing, the Trustee shall be under no obligation to exercise any of its rights or powers hereunder at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security reasonably satisfactory to the Trustee against any loss, liability or expense caused by taking such action.

Section 7.06. Limitation on Suits. Except as provided in Section 7.07 and Section 8.07 and except with respect to the right of any Holder to convert its Notes, no Holder may institute any proceeding, judicial or otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

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

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

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

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

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

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

Section 7.07. Rights of Holders to Receive Payment; Suit Therefor. Notwithstanding any other provision of this Indenture, each Holder shall have the right to receive payment or delivery, as the case may be, of (i) the principal (including the Fundamental Change Purchase Price, if applicable) of, (ii) accrued and unpaid interest on and (iii) the consideration due upon conversion of, its Notes, on or after the respective due dates expressed or provided for in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, and such right to receive such payment or delivery, as the case may be, on or after such respective dates shall not be impaired or affected without the consent of such Holder and shall not be subject to the requirements of Section 7.06. Payments of the Fundamental Change Purchase Price, cash due upon conversion, principal and interest that are not made when due shall accrue interest per annum at the then-applicable interest rate plus one percent from the applicable due date expressed in this Indenture.

Section 7.08. Collection Suit by Trustee. If an Event of Default specified in Section 7.01(a)(i) or 7.01(a)(ii) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest, if any, to the extent lawful) and the amounts provided for in Section 8.06.

Section 7.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, if the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 8.06.

Section 7.10. Priorities. If the Trustee collects any money pursuant to this Article 7, or after an Event of Default any moneys or properties distributable in respect of the Company’s or any Subsidiary Guarantor’s obligations under this Indenture, it shall pay out the money in the following order:

FIRST: to the Trustee (including any predecessor trustee) for amounts due under Section 8.06;

SECOND: to Holders for amounts due and unpaid on the Notes for principal, accrued and unpaid interest, if any, payment of the Fundamental Change Purchase Price (if applicable) and the cash (if any) deliverable upon conversion of Notes then submitted for conversion, as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Notes; and

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

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 7.10. At least 15 days before such record date, the Company shall mail to each Holder and the Trustee a notice that states the record date, the payment date and the amount to be paid.

Section 7.11. 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 7.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 7.07 or a suit by Holders of more than 10% in aggregate principal amount of the Notes at the time outstanding.

Section 7.12. Waiver of Stay or Extension Laws. None of the Company and any Subsidary Guarantor (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each of the Subsidiary Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

If a Default or Event of Default occurs, is continuing and is known to the Trustee, the Trustee shall mail to each Holder notice of such Default or Event of Default within 90 days after it occurs; provided that except in the case of a Default described in Section 7.01(a)(i), 7.01(a)(ii) or 7.01(a)(iii), the Trustee may withhold the notice if and so long as a committee of Trust Officers of the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

Section 8.06. Compensation and Indemnity.

(a) The Company and the Subsidiary Guarantors, jointly and severally, shall pay to the Trustee from time to time such compensation as shall be agreed upon from time to time in writing for its services. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket fees, expenses, disbursements and advances incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation, fees and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company and the Subsidiary Guarantors, jointly and severally, shall fully indemnify each of the Trustee and each predecessor Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) incurred by it arising out of or in connection with the acceptance or administration of this trust or trusts and the performance of its duties hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, the Subsidiary Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section 8.06. The Trustee shall notify the Company and any relevant Subsidiary Guarantor promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company or such Subsidiary Guarantor of any claim for which it may seek indemnity of which a Trust Officer has actually received written notice shall not relieve the Company or Subsidiary Guarantor, as applicable, of its obligations hereunder except to the extent such failure shall have materially prejudiced the Company or the Subsidiary Guarantor, as applicable. The Company and/or Subsidiary Guarantor, as applicable, shall defend the claim and the Trustee shall cooperate in the defense. If the Trustee is advised by counsel in writing that it may have available to it defenses which are in conflict with the defenses available to the Company and/or Subsidiary Guarantor, then the Trustee may have separate counsel and the Company and/or Subsidiary Guarantor, as applicable, shall 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 gross negligence. 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 shall extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns.

(b) To secure the Company’s payment obligations under this Section 8.06, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay the principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price on particular Notes.

(c) The Company’s payment obligations pursuant to this Section 8.06 shall survive the resignation or removal of the Trustee, the termination for any reason of this Indenture and the satisfaction and discharge of this Indenture. If the Trustee incurs expenses or renders services after the occurrence of a Default specified in Section 7.01(a)(x) or Section 7.01(a)(xi) with respect to the Company, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under applicable federal or state bankruptcy, insolvency or other similar law.

(d) “Trustee” for purposes of this Section 8.06 shall include any predecessor Trustee; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

Section 8.07. Replacement of Trustee. (a) The Trustee may resign at any time by notifying the Company in writing and by mailing notice thereof to the Holders at their addresses as they shall appear on the Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor Trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor Trustee. If no successor Trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation to the Holders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the Holders, petition any court of competent jurisdiction for the appointment of a successor Trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may on behalf of himself or herself and all others similarly situated, petition any such court for the appointment of a successor Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor Trustee.

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

(i) the Trustee shall cease to be eligible in accordance with the provisions of Section 8.10 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(ii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in either case, the Company may by a Board Resolution remove the Trustee and appoint a successor Trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor Trustee, or any Holder who has been a bona fide holder of a Note or Notes for at least six months may, on behalf of himself or herself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor Trustee.

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

(d) Any resignation or removal of the Trustee and appointment of a successor Trustee pursuant to any of the provisions of this Section 8.07 shall become effective upon acceptance of appointment by the successor Trustee as provided in Section 8.08.

Section 8.08. Acceptance by Successor Trustee. Any successor Trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor Trustee, the Trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 8.06, execute and deliver an instrument transferring to such successor Trustee all the rights and powers of the Trustee so ceasing to act. Upon request of any such successor Trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a lien prior to the Notes on all money or property held or collected by the Trustee, other than money or property held in trust to pay the principal, accrued and unpaid interest, if any, or payment of the Fundamental Change Purchase Price on particular Notes, to secure any amounts then due it pursuant to the provisions of Section 8.06.

No successor Trustee shall accept appointment as provided in this Section 8.08 unless at the time of such acceptance such successor Trustee shall be eligible under the provisions of Section 8.10.

Upon acceptance of appointment by a successor Trustee as provided in this Section 8.08, each of the Company and the successor Trustee, at the written direction and at the expense of the Company shall mail or cause to be mailed notice of the succession of such Trustee hereunder to the Holders at their addresses as they shall appear on the Register. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the Company.

Section 8.09. Successor Trustee by Merger. (a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets (including administration of this Indenture) to, another Person, the resulting, surviving or transferee Person without any further act shall be the successor Trustee; provided that if such successor Trustee is not eligible to act as Trustee pursuant to Section 8.10, such successor Trustee shall promptly resign pursuant to Section 8.07.

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

Section 8.10. Eligibility; Disqualification. The Trustee must be a Person who is eligible to act as an indenture trustee under the TIA and must have a combined capital and surplus of at least $50,000,000. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Article.

Section 8.11. 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 shall be taken or such omission shall be effective. The Trustee shall 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 shall not be less than three Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have 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 shall have received written instructions in response to such application specifying the action to be taken or omitted.

ARTICLE 9

DISCHARGE OF INDENTURE

Section 9.01. Discharge of Liability on Notes. When (a) the Company delivers to the Registrar all outstanding Notes (other than Notes replaced pursuant to Section 2.07) for cancellation or (b) all outstanding Notes have become due and payable, whether at the Maturity Date, at any Fundamental Change Purchase Date, upon conversion or otherwise, and the Company irrevocably deposits with the Trustee or delivers to the Holders, as applicable, cash (and, if applicable, shares of Common Stock, solely to satisfy outstanding conversions) sufficient to pay, or satisfy the Company’s Conversion Obligation with respect to, all amounts due and owing on all outstanding Notes (other than Notes replaced pursuant to Section 2.07), and, in either case, the Company pays all other sums payable hereunder by the Company with respect to the outstanding Notes, then this Indenture shall, subject to Section 8.06, cease to be of further effect with respect to the Notes, any Holders or each Subsidiary Guarantor’s obligations under its Subsidiary Guarantee. The Trustee shall acknowledge satisfaction and discharge of this Indenture with respect to the Notes on demand of the Company accompanied by an Officer’s Certificate and an Opinion of Counsel and at the cost and expense of the Company.

ARTICLE 10

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

Section 10.03. Execution of Supplemental Indentures. Upon the request of the Company, the Trustee shall sign any supplemental indenture authorized pursuant to this Article 10. In executing any supplemental indenture hereto, the Trustee shall receive, and (subject to the provisions of Section 8.01) shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel stating that such supplemental indenture is authorized and permitted under this Indenture.

However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives the notice of revocation before the date the supplemental indenture setting forth the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective in accordance with the terms of the supplemental indenture, which shall become effective upon the execution thereof by the Trustee.

The Company may, but shall not be 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.

ARTICLE 11

CONVERSIONS

Section 11.01. Conversion Privilege and Consideration.

(a) Subject to and upon compliance with the provisions of this Indenture, a Holder shall have the right, at such Holder’s option, to convert the principal amount of its Notes, or any portion of such principal amount that is equal to $1,000 or an integral multiple in excess thereof, (i) subject to satisfaction of the conditions described in Section 11.01(b), at any time prior to the Close of Business on the Business Day immediately preceding April 15, 2017 under the circumstances and during the periods set forth in Section 11.01(b), and (ii) irrespective of the conditions described in Section 11.01(b), on or after April 15, 2017 and prior to the Close of Business on the Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 445.6328 shares of Common Stock (subject to adjustment as provided in this Article 11, the “Conversion Rate”) per $1,000 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 11.03, the “Conversion Obligation”).

(b)

(i) Prior to the Close of Business on the Business Day immediately preceding April 15, 2017, a Holder may surrender all of its Notes, or any portion of the principal amount of its Notes that is equal to $1,000 or an integral multiple in excess thereof, for conversion during any calendar quarter (and only during such calendar quarter) commencing after September 30, 2012, if, for at least 20 Trading Days (whether or not consecutive) during the 30 consecutive Trading Day period ending on the last Trading Day of the immediately preceding calendar quarter, the Closing Sale Price of the Common Stock on such Trading Day is greater than or equal to 120% of the Conversion Price on such Trading Day (such condition, the “Sale Price Condition”). The Company shall determine whether the Sale Price Condition has been met and the Notes are convertible. If the Sale Price Condition has been met, the Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) of its satisfaction and of the resulting right of Holders to convert their Notes within one Business Day of the Sale Price Condition being met.

(ii) Prior to the Close of Business on the Business Day immediately preceding April 15, 2017, a Holder may surrender all of its Notes, or any portion of the principal amount of its Notes that is equal to $1,000 or an integral multiple in excess thereof, for conversion during the five consecutive Business Day period immediately following any five consecutive Trading Day period (the “Measurement Period”) in which, for each Trading Day of such Measurement Period, the Trading Price per $1,000 principal amount of Notes (as determined following a request by a Holder in accordance with the procedures set forth in this Section 11.01(b)(ii) and the definition of “Trading Price” in Section 1.01), was less than 98% of the product of (x) the Closing Sale Price of the Common Stock on such Trading Day and (y) the Conversion Rate on such Trading Day (such product, the “Intrinsic Value,” and such condition, the “Trading Price Condition”). The Trading Prices shall be determined by the Company pursuant to this Section 11.01(b)(ii) and the definition of Trading Price in Section 1.01. The Company shall provide written notice, including detailed contact information, to the Bid Solicitation Agent (if other than the Company) of the three independent nationally recognized independent securities dealers selected by the Company, and not the Bid Solicitation Agent, pursuant to the definition of “Trading Price” in Section 1.01 who are available and willing to furnish secondary market bid quotations, along with appropriate contact information for each.

(A) The Bid Solicitation Agent shall have no obligation to obtain secondary market bid quotations unless the Company has requested, in writing, that the Bid Solicitation Agent do so. The Company shall have no obligation to make such a request or determine the Trading Price unless one or more Holders of at least $1,000,000 aggregate principal amount of Notes (x) provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on the immediately following Trading Day would be less than 98% of the Intrinsic Value of the Notes on such Trading Day and (y) requests that the Company request the Bid Solicitation Agent obtain such bids.

(B) Upon receipt from a Holder of such evidence and such a request, the Company shall instruct the Bid Solicitation Agent to obtain such bids and the Company will determine the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until a Trading Day occurs in which the Trading Price per $1,000 principal amount of Notes for such Trading Day is greater than or equal to 98% of the Intrinsic Value of the Notes on such Trading Day.

(C) The Company shall determine the Trading Price based upon the secondary market bid quotations the Company receives from the Bid Solicitation Agent, whether the Trading Price Condition has been met on any Trading Day and whether the Notes are convertible on each of the next five consecutive Business Days. If the Trading Price Condition has been met on any Trading Day, the Company shall notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) on such Trading Day of its satisfaction and of the resulting right of Holders to convert their Notes on each of the next five consecutive Business Days. If, on any Trading Day after the Trading Price Condition has been met, the Company determines, based on secondary market bid quotations obtained by the Bid Solicitation Agent, that the Trading Price per $1,000 principal amount of Notes for such Trading Day is greater than or equal to 98% of the Intrinsic Value of the Notes on such Trading Day, the Company shall promptly so notify the Holders, the Trustee and the Conversion Agent (if other than the Trustee) that the Trading Price Condition is no longer met.

(iii) If, prior to the Close of Business on April 15, 2017, the Company elects to:

(A) issue to all or substantially all holders of the Common Stock rights, options or warrants entitling them, for a period of not more than 60 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share of Common Stock less than the average of the Closing Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or

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

then, in either case, at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution, the Company shall mail notice to the Holders and the Trustee describing such issuance or distribution, the Holders’ rights to convert their

Notes in accordance with this Section 11.01(b)(iii), the Conversion Rate in effect on the date the Company mails such notice, any adjustments to the Conversion Rate that must be made as a result of such issuance or distribution, and the effective date for any such adjustments. Once the Company has given such notice to the Holders, a Holder may surrender all of its Notes, or any portion of the principal amount of its Notes that is equal to $1,000 or an integral multiple in excess thereof, for conversion at any time until the earlier of (x) the Close of Business on the Business Day immediately preceding such Ex-Dividend Date and (y) the Company’s announcement that such issuance or distribution will not take place, in each case, even if the Notes are not otherwise convertible at such time.

(iv) If, prior to the Close of Business on April 15, 2017, the Company or any third party publicly announces a transaction or event that would, if consummated, constitute a Fundamental Change, a Make-Whole Fundamental Change or Share Exchange Event, regardless of whether Holders would have the right to require the Company to purchase their Notes pursuant to Section 3.01, or any such transaction or event occurs without any public announcement, the Company shall mail notice (a “Specified Corporate Transaction Notice”) of such transaction or event to the Holders and the Trustee within one Business Day of the first public announcement of such transaction or event or, in the case that no public announcement is made, the occurrence of such transaction or event. Upon receiving notice or otherwise becoming aware of a potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, the Company shall announce or cause the announcement of such potential transaction or event in time to deliver the related Specified Corporate Transaction Notice at least 45 Scheduled Trading Days prior to the anticipated effective date for such potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event. For any such potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, the Specified Corporate Transaction Notice shall describe:

(A) the potential transaction or event;

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

(D) the Conversion Rate in effect on the date the Company mails such notice;

(E) that an adjustment to the Conversion Rate is expected to be made pursuant to Section 11.05 as a result of such transaction or event and the formula for determining such adjustment;

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

(G) whether the relevant transaction or event is expected to constitute a Fundamental Change, and, if so, that Holders will have the right to require the Company to purchase their Notes pursuant to Article 3; and

(H) whether the relevant transaction or event is expected to constitute a Make-Whole Fundamental Change, and, if so, that the Conversion Rate will be increased under Section 11.07 for Notes converted in connection with such Make-Whole Fundamental Change.

Upon the Company’s delivery of a Specified Corporate Transaction Notice with respect to any potential Fundamental Change, Make-Whole Fundamental Change or Share Exchange Event, a Holder may surrender all of its Notes, or any portion of the principal amount of its Notes that is equal to $1,000 or an integral multiple in excess thereof, for conversion from, and including, the Business Day immediately following the delivery of the related Specified Corporate Transaction Notice to, and including, the 35th Trading Day immediately following the effective date of such transaction or event or, if such transaction or event constitutes a Fundamental Change, the Business Day immediately preceding the related Fundamental Change Purchase Date.

Section 11.02. Conversion Procedure.

(a) To convert a Note or portion thereof, a Holder or beneficial owner, as the case may be, must (i) in the case of a Global Note, (A) comply with the procedures of the Depositary then in effect for converting a beneficial interest in a global note, (B) if applicable, pay all funds required under Sections 11.02(g) and 11.02(h) below and (C) comply with any requirements of the Conversion Agent, and (ii) in the case of a Certificated Note, (A) complete and manually sign the conversion notice in the form attached to such Certificated Note (a “Notice of Conversion”) or a facsimile of the Notice of Conversion, (B) deliver the Notice of Conversion, which is irrevocable, and the Certificated Note to the Conversion Agent, (C) if required, furnish appropriate endorsements and transfer documents, (D) if applicable, pay all funds required under Section 11.02(h) below, and (E) if applicable, pay all funds required under Section 11.02(g) below.

(b) A Note shall be deemed to have been converted at the Close of Business on the first Business Day (the “Conversion Date”) on which (i) the Holder thereof satisfies all of the requirements set forth in Section 11.02(a) with respect to such Note and (ii) the conversion of such Note is not otherwise prohibited by Section 3.04(a) hereof. Subject to Section 11.07(e)(i) and Section 11.06, the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the third Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the third Business Day immediately following the last VWAP Trading Day of the relevant Observation Period, in the case of any other Settlement Method.

(c) If the last day during any period on which a Note may be converted is not a Business Day, the Note may be surrendered on the immediately following day that is a Business Day. Upon the conversion of a Note, the Conversion Agent, as promptly as possible, and in no event later than one Business Day immediately following the Conversion Date for the Note, will

provide the Company with notice of the conversion of the Note, and the Company, as promptly as possible, and in no event later than two Business Days after such Conversion Date, will notify the Trustee, if other than the Conversion Agent, of the conversion of the Note.

(d) If a Holder converts the entire principal amount of a Note, such Person will no longer be a Holder of such Note, except that (i) such Holder shall have the right hereunder to receive the consideration due upon conversion and (ii) if the relevant Conversion Date occurred between a Record Date and on or prior to the corresponding Interest Payment Date, the Holder of record of such Note shall have the right to receive the related interest payment on such Interest Payment Date.

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

(f) If any shares of Common Stock are issuable upon the conversion of a Note, the Person in whose name the certificate or certificates for such shares of Common Stock will be registered shall become the holder of record of such shares as of the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last VWAP Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be, for such Note.

(g) Notwithstanding Section 11.03(d), if a Holder converts its Note after the Close of Business on a Record Date but prior to the Open of Business on the Interest Payment Date corresponding to such Record Date, the Holder of such Note at the Close of Business on such Record Date shall receive the full amount of interest payable on such Note on such corresponding Interest Payment Date, notwithstanding the conversion. Any Note converted during the period beginning at the Close of Business on any Record Date and ending at the Open of Business on the Interest Payment Date corresponding to such Record Date must be accompanied by funds equal to the full amount of interest payable on such Note on such corresponding Interest Payment Date; provided, however, that no such payment need be made: (i) for Notes surrendered for conversion after the Close of Business on the Record Date immediately preceding the Maturity Date, (ii) if the Company has specified a Fundamental Change Purchase Date that is after such Record Date and on or prior to such corresponding Interest Payment Date or (iii) to the extent of any Defaulted Interest, if any Defaulted Interest exists at the time of conversion with respect to such Note.

(h) If a Holder converts a Note, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issuance of any shares of Common Stock upon such conversion; provided that if such tax is due because such converting Holder requested that such shares of Common Stock be issued in a name other than such Holder’s name, such Holder shall pay such tax.

(i) The Company shall make all determinations of whether the Notes are convertible at any time in accordance with this Indenture.

Section 11.03. Settlement Upon Conversion.

(a) Except as provided in Section 11.07(e), upon conversion of any Note, the Company shall pay or deliver, as the case may be, to a converting Holder, in respect of each $1,000 principal amount of Notes being converted, cash (“Cash Settlement”), shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 11.03(b) (“Physical Settlement”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of any fractional share of Common Stock in accordance with Section 11.03(b) (“Combination Settlement”), at its election, as set forth in this Section 11.03.

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

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

(iii) If, in respect of any Conversion Date (or any conversion occurring during the period from, and including, April 15, 2017 to, and including, the Business Day immediately preceding the Maturity Date, as the case may be), the Company elects to deliver a notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company, through the Trustee, shall deliver such Settlement Notice to converting Holders no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions occurring on or after April 15, 2017, no later than April 15, 2017). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be equal to $1,000. Any Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Conversion Obligation but does not indicate a Specified Dollar Amount per $1,000 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. Notwithstanding the foregoing or anything to the contrary herein, the Company shall not have the right to elect Physical Settlement in respect of Notes surrendered for conversion on any Conversion Date (or on

or after April 15, 2017, as the case may be) if the sum of (x) the aggregate number of shares of the Common Stock to be delivered upon Physical Settlement in satisfaction of the Company’s Conversion Obligation in respect of all Notes surrendered for conversion on such Conversion Date (or that would be delivered upon Physical Settlement if all Notes outstanding as of April 15, 2017 were surrendered for conversion, as the case may be) and (y) the aggregate number of shares of the Common Stock delivered or to be delivered in respect of Notes converted prior to such Conversion Date (or prior to April 15, 2017, as the case may be) is greater than the Maximum Number of Underlying Shares.

(iv) The cash, shares of Common Stock or combination of cash and shares of Common Stock due upon any conversion of Notes (the “Settlement Amount”) shall be computed as follows:

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

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 35 consecutive VWAP Trading Days during the relevant Observation Period; and

(C) subject to Section 11.03(b), if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to the converting Holder in respect of each $1,000 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 35 consecutive VWAP Trading Days during the relevant Observation Period.

(b) Notwithstanding anything herein to the contrary, in respect of any conversion of Notes, regardless of whether the Company has a class of securities listed on The New York Stock Exchange at the time of such conversion, the aggregate number of shares of the Common Stock delivered in respect of such conversion, when aggregated with the aggregate number of shares of the Common Stock previously delivered or required to be delivered in respect of all Notes surrendered for conversion prior to such conversion, cannot exceed 19.9% of the total number of shares of the Common Stock outstanding on the Issue Date unless, prior to such conversion, the Company has received approval from its shareholders to permit the issuance upon conversion of the Notes of a number of shares of the Common Stock up to the Maximum Number of Underlying Shares. If the Company receives such shareholder approval on any day, the Company shall so notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) prior to the Close of Business on such day. Prior to the Company obtaining such shareholder approval, in connection with any conversion of Notes for which the Company has

elected Combination Settlement, if the number of shares of Common Stock deliverable in respect of such conversion, when aggregated with the aggregate number of shares of the Common Stock delivered or required to be delivered in respect of Notes converted prior to such conversion, exceeds 19.9% of the total number of shares of the Common Stock outstanding on the Issue Date, the Company shall pay cash in lieu of delivering any shares of Common Stock otherwise deliverable upon conversion in excess of such limitations based on the Daily VWAP on each VWAP Trading Day of the relevant Observation Period in respect of which, in lieu of delivering shares of Common Stock, the Company pays cash pursuant to this Section 11.03(b).

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

(d) If a Holder converts a Note, except as set forth in Section 11.02(g), (i) such Holder shall not receive any separate cash payment (in addition to the Conversion Obligation) for accrued and unpaid interest on such Note and (ii) the Company’s payment and/or delivery, as the case may be, to such converting Holder of the amount of cash, the number of shares of Common Stock or a combination thereof, as the case may be, into which such Holder’s Note is convertible shall be deemed to satisfy in full the Company’s obligation to pay to such Holder (i) the principal amount of such converted Note and (ii) accrued and unpaid interest, if any, to, but excluding, the relevant Conversion Date. As a result, subject to Section 11.02(g), accrued and unpaid interest, if any, on a converted Note to but, excluding, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, subject to Section 11.02(g), accrued and unpaid interest, if any, shall be deemed to be paid first out of the cash paid upon such conversion.

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

Section 11.04. Covenants Relating to Underlying Shares.

(a) The Company covenants that any shares of Common Stock delivered upon conversion of the Notes shall be duly and validly issued and fully paid and nonassessable, and shall be free from preemptive rights and shall be free of any lien or adverse claim or from any taxes or charges with respect to the issue thereof.

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

(c) In addition, the Company will cause any such shares of Common Stock to be listed on any stock exchange on which the Common Stock is then listed and will comply with any stock exchange rules applicable to the Notes and/or any Common Stock issuable upon conversion of the Notes.

Section 11.05. Adjustments to the Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as described in this Section 11.05, except that the Company shall not make any adjustments to the Conversion Rate if Holders participate (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 any of the transactions described below in this Section 11.05 without having to convert their Notes as if they held a number of shares of the Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

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


CR₁ = CR₀ x	OS₁
CR₁ = CR₀ x		OS₀

where:


CR₀		= the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the Effective Date of such share split or combination, as the case may be;

CR₁		= the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such Effective Date, as the case may be;

OS₀		= the number of shares of the Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such Effective Date, as the case may be; and



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

Any adjustment made under this Section 11.05(a) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution or the Effective Date for such share split or combination, as the case may be. If any dividend or distribution of the type described in this Section 11.05(a) is declared but not so paid or made, then the Conversion Rate shall immediately be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect had such dividend or distribution not been declared. The “Effective Date,” with respect to a share split or combination, means the first date on which the shares of the Common Stock trade on the applicable exchange or on the applicable market, regular way, reflecting the relevant share split or share combination, as applicable.

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


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

where:



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

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

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

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

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

Any increase made under this Section 11.05(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase made upon the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If the Ex-Dividend Date for any such issuance occurs but such rights, options or warrants are not so issued, the Conversion Rate shall immediately be decreased to equal the Conversion Rate that would then be in effect had the relevant increase pursuant to this Section 11.05(b) not occurred.

For purposes of this Section 11.05(b) and Section 11.01(b)(iii)(A), in determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of the Common Stock at a price per share less than the average of the Closing Sale Prices of the Common Stock for each Trading Day in the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration that the Company receives for such rights, options or warrants and any amount payable upon exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors.

(i) If an Ex-Dividend Date occurs for a distribution by the Company of shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities to all or substantially all holders of the Common Stock, excluding (A) dividends, distributions or issuances, in each case, for which an increase is made pursuant to Sections 11.05(a) or 11.05(b); (B) dividends or distributions paid exclusively in cash for which an increase is made pursuant to Section 11.05(d); and (C) Spin-Offs for which an increase is made pursuant to Section 11.05(c)(ii) (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:


		CR₁ = CR₀ x		XX₀
		CR₁ = CR₀ x		XX₀ - FMV

where:


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

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


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

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

Notwithstanding the foregoing, if “SP₀” (as defined above) minus “FMV” (as defined above) is less than or equal to zero, then, in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Notes held, at the same time and upon the same terms as holders of the Common Stock without having to convert such Holder’s Notes, the amount and kind of Distributed Property that such Holder would have received as if such Holder had owned a number of shares of the Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such distribution.

Any increase made under this Section 11.05(c)(i) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If an Ex-Dividend Date for any such distribution occurs but such distribution is not so paid or made, or if any rights, options or warrants are distributed but not exercised before their expiration date, then the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect had the Ex-Dividend Date for such distribution not occurred, or to be the Conversion Rate that would then be in effect had solely the rights, options or warrants that were exercised been distributed, as the case may be.

(ii) If an Ex-Dividend Date occurs for a dividend or other distribution that consists of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company that are listed or admitted for trading (or will be listed or admitted for trading upon consummation of the Spin-Off) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:


		CR₁ = CR₀ x		FMV₀ + MP₀
		CR₁ = CR₀ x		MP₀

where:


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

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

FMV₀		= the average of the Closing Sale Prices of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock (determined by reference to the definition of Closing Sale Price as set forth in Section 1.01 as if references therein to Common Stock


		were to such Capital Stock or similar equity interest) over the first ten consecutive Trading Day period immediately following, and including, the Ex-Dividend Date for the Spin-Off (such period, the “Valuation Period”); and

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

Notwithstanding the foregoing, (A) if Cash Settlement or Combination Settlement is applicable to any conversion of Notes and the last VWAP Trading Day of the Observation Period for any such conversion of Notes occurs on or after the Ex-Dividend Date for the Spin-Off, but less than ten Trading Days immediately following, and including, the Ex-Dividend Date for the Spin-Off, references within this Section 11.05(c)(ii) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values and/or the affected Daily Settlement Amounts in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last VWAP Trading Day of such Observation Period, and (B) for purposes of determining the Conversion Rate applicable to any conversion of Notes for which the Conversion Date occurs during the ten Trading Days commencing on the Ex-Dividend Date for any Spin-Off, references within the portion of this Section 11.05(c)(ii) related to “Spin-Offs” to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, the relevant Conversion Date.

Any increase made pursuant to this Section 11.05(c)(ii) shall become effective as of the Open of Business on the Ex-Dividend Date for the Spin-Off. If an Ex-Dividend Date for a Spin-Off occurs but such Spin-Off does not become effective, the Conversion Rate shall be decreased to be the Conversion Rate that would have been in effect if the Ex-Dividend Date for such Spin-Off had not occurred.

For purposes of this Section 11.05(c) (and subject in all respect to Section 11.05(i)), rights, options or warrants distributed by the Company to all holders of its Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (A) are deemed to be transferred with such shares of the Common Stock; (B) are not exercisable; and (C) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 11.05(c) (and no increase to the Conversion Rate under this Section 11.05(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate increase (if any is required) to the Conversion Rate shall be made under this Section 11.05(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders

thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an increase to the Conversion Rate under this Section 11.05(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Conversion Rate shall be decreased as if such rights, options or warrants had not been issued and (y) the Conversion Rate shall then again be increased to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be decreased as if such rights, options and warrants had not been issued.

For purposes of Section 11.05(a), Section 11.05(b) and this Section 11.05(c), if any dividend or distribution to which this Section 11.05(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 11.05(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 11.05(b) is applicable (the “Clause B Distribution”),

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 11.05(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 11.05(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 11.05(a) and Section 11.05(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such Effective Date” within the meaning of Section 11.05(a) or “outstanding immediately prior to the Open of Business on such Ex-Dividend Date” within the meaning of Section 11.05(b).

(d) Adjustment for Cash Distributions. If an Ex-Dividend Date occurs for any cash dividend or distribution by the Company to all or substantially all holders of the outstanding Common Stock, then the Conversion Rate shall be increased based on the following formula:


		CR₁ = CR₀ x		XX₀
		CR₁ = CR₀ x		XX₀ - C

where:



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

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

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

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

If “SP₀” (as defined above) minus “C” (as defined above) is less than or equal to zero, then, in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Notes held, at the same time and upon the same terms as holders of the Common Stock without having to convert such Holder’s Notes, the amount of cash such Holder would have received if such Holder had owned a number of shares of the Common Stock equal to the Conversion Rate in effect on the Ex-Dividend Date for such dividend or distribution.

Any increase made under this Section 11.05(d) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. If an Ex-Dividend Date for any such dividend or distribution occurs but such dividend or distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect had such Ex-Dividend Date not occurred.

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


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

where:



CR₀		= the Conversion Rate in effect immediately prior to the Close of Business on the Expiration Date;



CR₁		= the Conversion Rate in effect immediately after the Close of Business on 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 the shares of Common Stock purchased in such tender or exchange offer;

OS₀		= the number of shares of Common Stock outstanding immediately prior to the time (the “Consummation Time”) such tender or exchange offer is consummated (prior to giving effect to the purchase of all shares of Common Stock accepted for purchase or exchange in such tender or exchange offer);

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

SP₁		= the average of the Closing Sale Prices of the Common Stock over the ten consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

The increase to the Conversion Rate under this Section 11.05(e) shall be given effect at the Close of Business on the Expiration Date. If Cash Settlement or Combination Settlement is applicable to any conversion of Notes and the Expiration Date is less than ten Trading Days prior to, and including, the last VWAP Trading Day of the Observation Period in respect of any such conversion of Notes, references within this Section 11.05(e) to ten Trading Days shall be deemed replaced, for purposes of calculating the affected Daily Conversion Values and/or the affected Daily Settlement Amounts in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last VWAP Trading Day of such Observation Period. For purposes of determining the Conversion Rate applicable to any conversion during the ten Trading Day period commencing on the Trading Day next succeeding the Expiration Date, references within this Section 11.05(e) to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding, the relevant Conversion Date.

(f) Holder Participation in Adjustment Events. Notwithstanding the provisions set forth in clauses (a) through (e) above, if any adjustment to the Conversion Rate pursuant to such provisions becomes effective on any Ex-Dividend Date, Effective Date, or Expiration Date and a Holder that has converted its Notes would (i) receive shares of Common Stock based on an adjusted Conversion Rate and (ii) be a record holder of such shares of Common Stock on the record date for the dividend, distribution, transaction or other event giving rise to such adjustment, then, in lieu of receiving shares of Common Stock at such an adjusted Conversion Rate and participating on an as-converted basis in such dividend, distribution, transaction or other event, such Holder shall receive a number of shares of Common Stock based on the unadjusted Conversion Rate and shall participate in the related dividend, distribution, transaction or other event giving rise to such adjustment.

(g) Adjustments Not Yet Effective. If any Holder converts its Note and, on any VWAP Trading Day during the Observation Period corresponding to the Conversion Date for such Note, shares of Common Stock are deliverable in respect of such VWAP Trading Day, and

(i) the occurrence of the Ex-Dividend Date for any dividend or distribution, the Effective Date for any share split or combination or the Expiration Date for any tender or exchange offer by the Company that, in each case, would require an adjustment to the Conversion Rate pursuant to Section 11.05(a), (b), (c), (d) or (e) occurs prior to the Company’s delivery of such shares of Common Stock to the converting Holder;

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

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

then the Company shall adjust the number of shares of Common Stock it delivers to such Holder in respect of such VWAP Trading Day in a manner that appropriately reflects the relevant dividend, distribution, transaction or event. As used solely in this Section 11.05(g), “record date” means, with respect to any dividend, distribution or other transaction or event in which the holders of the Common Stock (or other applicable security) have the right to receive any cash, securities or other property or in which the Common Stock (or such other security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of holders of the Common Stock (or such other security) entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors, statute, contract or otherwise).

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

(i) Rights Plans. To the extent that the Company has a shareholder rights plan in effect upon conversion of any Note, each share of Common Stock issued upon such conversion (x) shall be entitled to receive the number of rights, if any, associated with one share of Common Stock under such shareholder rights plan, and (y) shall, if issued in certificated form, bear such legends, if any, as may be required under such shareholder rights plan. In addition, if prior to the Conversion Date for such Note, the rights have separated from the Common Stock in accordance with the provisions of the applicable shareholder rights plan, at the time of such separation, the Conversion Rate shall be increased in accordance with Section 11.05(c) as if the Company made a distribution of Distributed Property to the holders of the Common Stock; provided, further, that such adjustment shall be subject to decreased upon the expiration, termination or redemption of such separated rights in accordance with Section 11.05(c).

(j) Deferral of Adjustments. The Company shall not be required to make an adjustment in the Conversion Rate unless such adjustment would result in a change of at least 1% in the Conversion Rate; provided that any adjustment of less than 1% that would have been made to the Conversion Rate but for this Section 11.05(j) shall be carried forward, and (i) all such carried forward adjustments, regardless of whether the aggregate adjustment is greater than 1% of the Conversion Rate, (i) upon any conversion of Notes (and on each VWAP Trading Day in the related Observation Period, if any) and (ii) upon any purchase of the Notes by the Company upon a Fundamental Change.

(k) Voluntary Increases. In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 11.05, and to the extent permitted by applicable law and any applicable stock exchange rules, from time to time, (i) the Company may increase the Conversion Rate of the Notes by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase is in the best interest of the Company and (ii) the Company may (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of the Common Stock or rights to purchase shares of the Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or a similar event. However, the Company shall not take any action that would result in adjustment of the Conversion Rate, pursuant to this Section 11.05(k), that would result in a reduction of the Conversion Price to less than the par value per share of the Common Stock.

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

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

(n) [Reserved].

(o) Notice of Adjustments. Whenever the Conversion Rate is adjusted as herein provided, the Company shall as promptly as practicable file with the Trustee (and the Conversion Agent, if not the Trustee) an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have received such Officer’s Certificate, the Trustee

shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume without inquiry that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which such adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each Holder at its last address appearing on the Register. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

Section 11.06. Effect of Reclassification, Consolidation, Merger or Sale.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a share subdivision or share combination for which an adjustment is provided pursuant to Section 11.05);

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

(iii) any sale, assignment, conveyance, lease, transfer or disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries; or

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock will be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Share Exchange Event,” any such stock, other securities or other property or assets, “Reference Property,” and the amount of Reference Property that a holder of one share of the Common Stock immediately prior to such Share Exchange Event would have been entitled to receive upon the occurrence of such Share Exchange Event, a “Unit of Reference Property”), then the Company or the successor, purchasing or transferee company, as the case may be, shall execute with the Subsidiary Guarantors and the Trustee a supplemental indenture providing that, at and after the effective time of such Share Exchange Event, a Holder’s right to convert its Note into cash, shares of Common Stock or a combination thereof shall be changed into the right to convert such Note into cash, Units of Reference Property or a combination thereof. However, at and after the effective time of such Share Exchange Event, (x) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes, as set forth under Section 11.03 and (y)(A) any amount payable in cash upon conversion of the Notes as set forth under Section 11.03 shall continue to be payable in cash, (B) in lieu of any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes as set forth under Section 11.03, the Company shall instead deliver the amount and type of Reference Property that a holder of that number of shares of the Common Stock would have received in such Share Exchange Event and (C) the Daily VWAP for any VWAP Trading Day shall be calculated based on the value of a Unit of Reference Property that a holder of one share of the Common Stock would have received in such Share Exchange Event.

If a Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the amount and kind of Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election, and (ii) the Unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders receive only cash in such Share Exchange Event, then for all conversions that occur after the effective date of such Share Exchange Event (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the relevant Conversion Date (as may be increased by any Additional Shares pursuant to Section 11.07), multiplied by the price paid per share of Common Stock in such Share Exchange Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments provided for in this Article 11. If the Reference Property in respect of any Share Exchange Event includes shares of stock, securities or other property or assets of a Person other than the Company or, in the case of a transaction described in Article 6, the Successor Company, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes, including the right of Holders to require the Company to purchase their Notes upon a Fundamental Change pursuant to Article 3, as the Board of Directors shall reasonably consider necessary by reason of the foregoing.

(b) When the Company executes a supplemental indenture pursuant to this Section 11.06, as promptly as practicable, the Company shall file with the Trustee an Officer’s Certificate briefly describing such Share Exchange Event, the composition of a Unit of Reference Property for such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent to such Share Exchange Event under this Indenture have been complied with. Any failure to deliver such Officer’s Certificate shall not affect the legality or validity of such supplemental indenture. The Company shall also issue a press release containing such information and shall make such press release available on its website.

(c) The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this Section 11.06. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination thereof, as set forth in Section 11.02 and Section 11.01 prior to the effective date of such Share Exchange Event.

(d) The provisions of this Section 11.06 shall apply successively to successive Share Exchange Events.

Section 11.07. Adjustment to Conversion Rate Upon Certain Transactions.

(a) If a Make-Whole Fundamental Change occurs and a Holder elects to convert its Note in connection with such Make-Whole Fundamental Change, the Company shall, in the circumstances described in this Section 11.07, increase the Conversion Rate for such Note by the number of additional shares of Common Stock (the “Additional Shares”) described in this Section 11.07. For the purposes of this Section 11.07, a conversion of Notes shall be deemed to be “in connection with” a Make-Whole Fundamental Change if the Conversion Date occurs during the period beginning on, and including, the date on which such Make-Whole Fundamental Change occurs or becomes effective (such date, the “Make-Whole Fundamental Change Effective Date”) and ending on, and including, the Business Day immediately preceding the earliest of (i) the 35th Scheduled Trading Day immediately following the Make-Whole Fundamental Change Effective Date, (ii) if such Make-Whole Fundamental Change is also a Fundamental Change, the relevant Fundamental Change Purchase Date, and (iii) the Business Day immediately preceding the Maturity Date. The Company shall notify Holders and the Trustee within one Business Day after the first public announcement by the Company or a third party of an event or transaction that the Company reasonably determines would, if consummated, constitute a Make-Whole Fundamental Change. Upon receiving notice or otherwise becoming aware of a potential Make-Whole Fundamental Change, the Company shall announce or cause the announcement of such potential Make-Whole Fundamental Change in time to deliver such notice at least 45 Scheduled Trading Days prior to the anticipated Make-Whole Fundamental Change Effective Date.

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

(c) The Stock Prices set forth in the column headings of the table in clause (d) below shall be adjusted as of any date on which the Conversion Rate is adjusted pursuant to Section 11.05. The adjusted Stock Prices shall equal the Stock Prices in effect immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment, and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table in clause (d) below shall be adjusted at the same time and in the same manner as the Conversion Rate is adjusted pursuant to Section 11.05.

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

July 15, 2017		89.1265		54.3672		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000		0.0000

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

(i) if the Stock Price is between two Stock Prices listed in the table or the Make-Whole Fundamental Change Effective Date is between two Make-Whole Fundamental Change Effective Dates listed in the table, the applicable number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Make-Whole Fundamental Change Effective Dates, as applicable, based on a 365-day year;

(ii) if the Stock Price is greater than $10.00 (subject to adjustment in the same manner and at the same time as the Stock Prices listed in the table), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $1.87 (subject to adjustment in the same manner and at the same time as the Stock Prices listed in the table), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding anything to the contrary in this Section 11.07, in no event shall the Conversion Rate exceed 534.7593 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment at the same time and in the same manner as the Conversion Rate pursuant to Section 11.05 (the “Maximum Conversion Rate”).

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

(i) that is described in clause (2) of the definition Fundamental Change and in which the holders of Common Stock receive only cash in consideration for their shares (a “Cash Merger”), notwithstanding anything to the contrary in Section 11.03, the Company shall satisfy its Conversion Obligation with respect to any Note converted at any time following such Cash Merger by delivering to the converting Holder, on the third Business Day immediately following the Conversion Date for such Note, an amount of cash, for each $1,000 principal amount of Notes converted, equal to the product of (A) the Conversion Rate in effect on such Conversion Date (as increased by any Additional Shares pursuant to this Section 11.07) and (B) the “Stock Price” with respect to such Cash Merger, which shall be the cash amount per share paid to holders of Common Stock in such Cash Merger; or

(ii) that is not a Cash Merger, (A) the “Stock Price” with respect to such Make-Whole Fundamental Change shall equal the average of the Closing Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the related Make-Whole Fundamental Change Effective Date, and (B) for the avoidance of doubt, the Company shall satisfy its Conversion Obligation with respect to any Note converted in connection with such Make-Whole Fundamental Change in accordance with Section 11.03, based on the Conversion Rate as increased by any Additional Shares pursuant to this Section 11.07.

Section 11.08. Trustee’s Disclaimer. Each of the Trustee, the Conversion Agent and the Bid Solicitation Agent has no duty to determine when an adjustment under this Article 11 should be made, how it should be made or what it should be. Neither the Trustee, the Conversion Agent nor the Bid Solicitation Agent shall be accountable for and makes no representation as to the validity or value of any securities or assets issued upon conversion of Notes. Each of the Trustee, the Conversion Agent and the Bid Solicitation Agent shall not be responsible for the Company’s failure to comply with the covenants or anything else contained in this Article 11. Each Conversion Agent and Bid Solicitation Agent (if other than the Company) shall have the same protection under this Section 11.08 as the Trustee.

Neither the Trustee, the Conversion Agent nor the Bid Solicitation Agent shall be responsible for determining whether any event contemplated by Section 11.01 has occurred which makes the Notes eligible for conversion until the Company has delivered to the Trustee, the Conversion Agent and the Bid Solicitation Agent an Officer’s Certificate stating that such event has occurred, on which Officer’s Certificate the Trustee, the Conversion Agent and the Bid Solicitation Agent may conclusively rely, and the Company agrees to deliver such Officer’s Certificate immediately after the occurrence of any such event.

The Trustee, the Conversion Agent and the Bid Solicitation Agent shall not at any time be under any duty or responsibility to any Holder to either calculate the Conversion Rate or determine whether any facts exist which may require any 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 herein, or in any supplemental indenture provided to be employed, in making the same and shall be protected in relying upon an Officer’s Certificate with respect to the same. Neither the Trustee, the Conversion Agent nor the Bid Solicitation Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common Stock or stock or share certificates or other securities or property upon the surrender of any Note for the purpose of conversion. Without limiting the generality of the foregoing, neither the Trustee, the Conversion Agent nor the Bid Solicitation Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 11.06 relating either to the kind or amount of shares of stock or securities or other property or assets (including cash) receivable for Holders upon the conversion of their Notes after an any event referred to in such Section 11.06 or to any adjustment to be made with respect thereto, but, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officer’s Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto.

ARTICLE 12

PAYMENT OF INTEREST

Section 12.01. Payment of Interest. The Company shall pay interest on the Notes at a rate of 5.00% per annum, payable semi-annually in arrears on January 15 and July 15 of each year (each, an “Interest Payment Date”) or, if any such day is not a Business Day, the immediately following Business Day, commencing January 15, 2013. Interest on the Notes shall accrue from the most recent date to which interest has been paid or duly provided for, or, if no interest has been paid, the date of this Indenture. Interest on a Note shall be paid to the Holder of record of such Note at the Close of Business on the January 1 or July 1, whether or not a Business Day (each, a “Record Date”), immediately preceding the January 15 or July 15 Interest Payment Date, respectively, and shall be computed on the basis of a 360-day year composed of twelve 30-day months. In the event of the conversion of a Note or purchase of a Note by the Company at the option of the Holder pursuant to Article 3, interest shall cease to accrue on such Note; provided that if any such conversion or repurchase occurs following a Record Date and on or prior to the related Interest Payment Date, the Holder of record of such Note as of the Close of Business on such Record Date shall receive the full amount of the related interest payment on such Interest Payment Date.

Section 12.02. Defaulted Interest. Any installment of interest that is payable, but is not punctually paid or duly provided for on any Interest Payment Date (“Defaulted Interest”), shall forthwith cease to be payable to the Holders in whose names the Notes were registered on the Record Date applicable to such installment of interest. Defaulted Interest (including any interest on such Defaulted Interest) may be paid by the Company, at its election, as provided in Sections 12.02(a) or 12.02(b).

(a) The Company may elect to make payment of any Defaulted Interest (including any interest on such Defaulted Interest) to the Holders in whose names the Notes are registered at the Close of Business on a special record date for the payment of such Defaulted Interest (a “Special Record Date”), which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest (including any interest on such Defaulted Interest) or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Holders entitled to such Defaulted Interest (including any interest on such Defaulted Interest) as provided in this Section 12.02(a). Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest (including any interest on such Defaulted Interest), which shall be not more than 15 calendar days and not less than ten calendar days prior to the date of the proposed payment and not less than ten calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest (including any interest on such Defaulted Interest) and the Special Record Date therefor to be sent by first-class mail, postage prepaid, to each Holder at such Holder’s address as it appears in the registration books of the Registrar, not less than ten calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest (including any interest on such Defaulted

Interest) and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest (including any interest on such Defaulted Interest) shall be paid to the Holders in whose names the Notes are registered at the Close of Business on such Special Record Date and shall no longer be payable pursuant to Section 12.02(b).

(b) Alternatively, the Company may make payment of any Defaulted Interest (including any interest on such Defaulted Interest) in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Section 12.02(b), such manner of payment shall be deemed practicable by the Trustee.

Section 12.03. Interest Rights Preserved. Subject to the foregoing provisions of this Article 12 and, to the extent applicable, Sections 2.06 and 2.07, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

Section 13.03. Call of Meetings by Company or Holders. In case at any time the Company, pursuant to a Board Resolution, or the Holders of at least 10% of the aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within 20 days after receipt of such request, then the Company or such Holders may determine the time and the place for such meeting and may call such meeting to take any action authorized in Section 13.01, by mailing notice thereof as provided in Section 13.02.

The chairman of the meeting shall have no right to vote other than by virtue of Notes held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the

Section 13.07. No Delay of Rights by Meeting. Nothing contained in this Article 13 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Notes.

SUBSIDIARY GUARANTEES

Section 14.01. The Subsidiary Guarantees. Subject to the provisions of this Article 14, each Subsidiary Guarantor hereby irrevocably and unconditionally guarantees, jointly and severally, on an unsecured basis, the full and punctual payment (whether at the Maturity Date, at the Fundamental Change Purchase Date, upon acceleration or otherwise) of the principal of, and interest on, and all other amounts or consideration payable or deliverable (as the case may be) under (including the Conversion Obligation), each Note, and the full and punctual payment of all other amounts or consideration payable or deliverable (as the case may be) by the Company under this Indenture (any such guaranty, a “Subsidiary Guarantee”). Upon failure by the Company to pay or deliver (as the case may be) punctually any such amount or consideration, each Subsidiary Guarantor shall forthwith on demand pay or deliver (as the case may be) the amount or consideration (as the case may be) not so paid or delivered (as the case may be) at the place and in the manner specified in this Indenture.

Section 14.02. Subsidiary Guarantee Unconditional. The obligations of each Subsidiary Guarantor hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released, discharged or otherwise affected by:

(1) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company under this Indenture or any Note, by operation of law or otherwise;

(2) any modification or amendment of or supplement to this Indenture or any Note;

(3) any change in the corporate existence, structure or ownership of the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company or its assets or any resulting release or discharge of any obligation of the Company contained in this Indenture or any Note;

(4) the existence of any claim, set-off or other rights which the Subsidiary Guarantor may have at any time against the Company, the Trustee or any other Person, whether in connection with this Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

(5) any invalidity or unenforceability relating to or against the Company for any reason of this Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment or delivery by the Company of the principal of or interest on any Note or any other amount or consideration payable or deliverable (as the case may be) by the Company under this Indenture; or

(6) any other act or omission to act or delay of any kind by the Company, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Subsidiary Guarantor’s obligations hereunder.

Section 14.03. Discharge; Reinstatement. Each Subsidiary Guarantor’s obligations hereunder will remain in full force and effect until the principal of and interest on the Notes and all other amounts or consideration payable or deliverable (as the case may be) by the Company under this Indenture have been paid or delivered (as the case may be) in full. If at any time any payment of the principal of or interest on any Note or any other amount or consideration payable or deliverable (as the case may be) by the Company under this Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Subsidiary Guarantor’s obligations hereunder with respect to such payment or delivery (as the case may be) will be reinstated as though such payment or delivery had been due but not made at such time.

Section 14.04. Waiver by the Subsidiary Guarantors. Each Subsidiary Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person.

Section 14.05. Subrogation and Contribution. Upon making any payment or delivery with respect to any obligation of the Company under this Article 14, the Subsidiary Guarantor making such payment or delivery (as the case may be) will be subrogated to the rights of the payee against the Company with respect to such obligation, provided that the Subsidiary Guarantor may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any other Subsidiary Guarantor with respect to such payment or delivery so long as any amount payable or deliverable by the Company hereunder or under the Notes remains unpaid or undelivered (as the case may be).

Section 14.06. Stay of Acceleration. If acceleration of the time for payment or delivery of any amount payable or deliverable (as the case may be) by the Company under this Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts and/or consideration otherwise subject to acceleration under the terms of this Indenture are nonetheless payable and/or deliverable (as the case may be) by the Subsidiary Guarantors hereunder forthwith on demand by the Trustee or the Holders.

Section 14.07. Limitation on Amount of Subsidiary Guarantee. Notwithstanding anything to the contrary in this Article 14, each Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Subsidiary Guarantor not constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each Subsidiary Guarantor under its Subsidiary Guarantee are limited to the maximum amount that would not render the Subsidiary Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

Section 14.08. Execution and Delivery of Subsidiary Guarantee. The execution by each Subsidiary Guarantee of this Indenture (or a supplemental indenture in accordance with the terms hereunder) evidences the Subsidiary Guarantee of such Subsidiary Guarantor, whether or not the person signing as an officer of the Subsidiary Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of each Subsidiary Guarantor.

Section 14.09. Release of Subsidiary Guarantee. (a) The Subsidiary Guarantee of a Subsidiary Guarantor will terminate upon:

(i) a sale or other disposition (including by way of consolidation or merger) of the Subsidiary Guarantor such that it ceases to be a Subsidiary of the Company; or

(ii) discharge of the Notes, as provided in Article 9.

(b) Upon delivery by the Company to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the foregoing effect, the Trustee will execute any documents reasonably required in order to evidence the release of the Subsidiary Guarantor from its obligations under its Subsidiary Guarantee.

[FORM OF REVERSE OF NOTE]

CAL DIVE INTERNATIONAL, INC.

This Note is one of a duly authorized issue of Notes of the Company, designated as its 5.00% Convertible Senior Notes due 2017 (the “Notes”), limited to the aggregate principal amount of $86,250,000 all issued or to be issued under and pursuant to an Indenture dated as of July 18, 2012 (the “Indenture”), among the Company, the subsidiary guarantors party thereto (the “Subsidiary Guarantors,” as more fully set forth in the Indenture) and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company, the Subsidiary Guarantors and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture. This Note is guaranteed by the Subsidiary Guarantors as set forth in the Indenture.

In case certain Events of Default (other than an Event of Default specified in Section 7.01(a)(x) or 7.01(a)(xi) of the Indenture with respect to the Company), as defined in the Indenture, shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of at least 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Purchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company, the Subsidiary Guarantors and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay or deliver, as the case may be, the principal (including the Fundamental Change Purchase Price, if applicable) of, accrued and unpaid interest on, and the consideration due upon conversion of, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed.

A-6

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

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

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

Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the Close of Business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple in excess thereof, into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, based on the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.

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