Section 2.01. Form, Dating and Denominations.

Section 2.02. Initial Notes and Additional Notes; Execution and Authentication.

Section 2.03. Method of Payment.

(A) Global Notes.  The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity Date, Redemption on a Redemption Date, Optional Repurchase on an Optional Repurchase Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration for, any Global Note to the Depositary by wire transfer of immediately available funds no later than the time the same is due as provided in this Indenture.

(B) Physical Notes.  The Company will pay, or cause the Paying Agent to pay, the principal (whether due upon maturity on the Maturity Date, Redemption on a Redemption Date, Optional Repurchase on an Optional Repurchase Date or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest on, and any cash Conversion Consideration for, any Physical Note no later than the time the same is due as provided in this Indenture as follows: (i) if the principal amount of such Physical Note is at least five million dollars ($5,000,000) (or such lower amount as the Company may choose in its sole and absolute discretion) and the Holder of such Physical Note entitled to such payment has delivered to the Paying Agent or the Trustee, no later than the time set forth in the immediately following sentence, a written request that the Company make such payment by wire transfer to an account of such Holder within the United States, by wire transfer of immediately available funds to such account; and (ii) in all other cases, by check mailed to the address of the Holder of such Physical Note entitled to such payment as set forth in the Register.  To be timely, such written request must be so delivered no later than the Close of Business on the following date: (x) with respect to the payment of any interest due on an Interest Payment Date, the immediately preceding Regular Record Date; (y) with respect to any cash Conversion Consideration, the relevant Conversion Date; and (z) with respect to any other payment, the date that is fifteen (15) calendar days immediately before the date such payment is

due.

Section 2.04. Accrual of Interest; Defaulted Amounts; When Payment Date is Not a Business Day.

(A) Accrual of Interest.  Each Note will accrue interest at a rate per annum equal to 5.00% (the “Stated Interest”), plus any Special Interest that may accrue pursuant to ‎Section 7.03.  Stated Interest on each Note will (i) accrue from, and including, the most recent date to which Stated Interest has been paid or duly provided for (or, if no Stated Interest has theretofore been paid or duly provided for, the date set forth in the certificate representing such Note as the date from, and including, which Stated Interest will begin to accrue in such circumstance) to, but excluding, the date of payment of such Stated Interest; and (ii) be, subject to Sections ‎4.02(D),  ‎4.03(C) and ‎4.04(E) (but without duplication of any payment of interest), payable semi-annually in arrears on each Interest Payment Date, beginning on the first Interest Payment Date set forth in the certificate representing such Note, to the Holder of such Note as of the Close of Business on the immediately preceding Regular Record Date.  Stated Interest, and, if applicable, Special Interest, on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(B) Defaulted Amounts.  If the Company fails to pay any amount (a “Defaulted Amount”) payable on a Note on or before the due date therefor as provided in this Indenture, then, regardless of whether such failure constitutes an Event of Default, (i) such Defaulted Amount will forthwith cease to be payable to the Holder of such Note otherwise entitled to such payment; (ii) to the extent lawful, interest (“Default Interest”) will accrue on such Defaulted Amount at a rate per annum equal to the rate per annum at which Stated Interest accrues, from, and including, such due date to, but excluding, the date of payment of such Defaulted Amount and Default Interest; (iii) such Defaulted Amount and Default Interest will be paid on a payment date selected by the Company to the Holder of such Note as of the Close of Business on a special record date selected by the Company, provided that such special record date must be no more than fifteen (15), nor less than ten (10), calendar days before such payment date; and (iv) at least fifteen (15) calendar days before such special record date, the Company will send notice to the Trustee and the Holders that states such special record date, such payment date and the amount of such Defaulted Amount and Default Interest to be paid on such payment date.

(C) Delay of Payment when Payment Date is Not a Business Day.  If the due date for a payment on a Note as provided in this Indenture is not a Business Day, then, notwithstanding anything to the contrary in this Indenture or the Notes, such payment may be made on the immediately following Business Day and no interest will accrue on such payment as a result of the related delay.  Solely for purposes of the immediately preceding sentence, a day on which the applicable place of payment is authorized or required by law or executive order to close or be closed will be deemed not to be a “Business Day.”

Section 2.05. Registrar, Paying Agent and Conversion Agent.

(A) Generally.  The Company will maintain (i) an office or agency in the contiguous United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the contiguous United States where Notes may be

presented for payment (the “Paying Agent”); and (iii) an office or agency in the contiguous United States where Notes may be presented for conversion (the “Conversion Agent”).  If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, then the Trustee will act as such; provided that no office of the Trustee will be an office or agency of the Company for purposes of service of legal process against the Company.  For the avoidance of doubt, the Company or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent. The Company will give prompt written notice to the Trustee of any change in the location of any such office or agency.

(B) Duties of the Registrar.  The Registrar will keep a record (the “Register”) of the names and addresses of the Holders, the Notes held by each Holder and the transfer, exchange, repurchase, Redemption and conversion of Notes.  Absent manifest error, the entries in the Register will be conclusive and the Company and the Trustee may treat each Person whose name is recorded as a Holder in the Register as a Holder for all purposes.  The Register will be in written form or in any form capable of being converted into written form reasonably promptly.

(C) Co-Agents; Company’s Right to Appoint Successor Registrars, Paying Agents and Conversion Agents.  The Company may appoint one or more co-Registrars, co-Paying Agents and co-Conversion Agents, each of whom will be deemed to be a Registrar, Paying Agent or Conversion Agent, as applicable, under this Indenture.  Subject to ‎Section 2.05(A), the Company may change any Registrar, Paying Agent or Conversion Agent (including appointing itself or any of its Subsidiaries to act in such capacity) without notice to any Holder.  The Company will notify the Trustee (and, upon request, any Holder) of the name and address of each Note Agent, if any, not a party to this Indenture and will enter into an appropriate agency agreement with each such Note Agent, which agreement will implement the provisions of this Indenture that relate to such Note Agent.

(D) Initial Appointments.  The Company hereby appoints the Trustee as the initial Paying Agent, the initial Registrar and the initial Conversion Agent.

Section 2.06. Paying Agent and Conversion Agent to Hold Property in Trust.

Section 2.07. Legends.

(A) Global Note Legend.  Each Global Note will bear the Global Note Legend (or any similar legend, not inconsistent with this Indenture, required by the Depositary for such Global Note).

(B) Other Legends.  A Note may bear any other legend or text, not inconsistent with this Indenture, as may be required by applicable law or by any securities exchange or automated quotation system on which such Note is traded or quoted.

(C) Acknowledgement and Agreement by the Holders.  A Holder’s acceptance of any Note bearing any legend required by this ‎Section 2.07 will constitute such Holder’s acknowledgement of, and agreement to comply with, the restrictions set forth in such legend.

Section 2.08. Transfers and Exchanges.

(A) Provisions Applicable to All Transfers and Exchanges.

(i) Subject to this ‎Section 2.08, Physical Notes and beneficial interests in Global Notes may be transferred or exchanged from time to time and the Registrar will record each such transfer or exchange in the Register.

(ii) Each Note issued upon transfer or exchange of any other Note (such other Note being referred to as the “old Note” for purposes of this ‎Section 2.08(A)(ii)) or portion thereof in accordance with this Indenture will be the valid obligation of the Company, evidencing the same indebtedness, and entitled to the same benefits under this Indenture, as such old Note or portion thereof, as applicable.

(iii) The Company, the Trustee and the Note Agents will not impose any service charge on any Holder for any transfer, exchange or conversion of Notes, but the Company, the Trustee, the Registrar and the Conversion Agent may require payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Notes, other than exchanges pursuant to Sections ‎2.09,  ‎2.12 or ‎9.05 not involving any transfer.

(iv) Notwithstanding anything to the contrary in this Indenture or the Notes, a Note may not be transferred or exchanged in part unless the portion to be so transferred or exchanged is in an Authorized Denomination.

(v) The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any transfer restrictions imposed by applicable law or under this Indenture with respect to any transfer of any interest in any Note or any share of Common Stock issued upon conversion of any Note (including any transfers between or among the

Depositary, 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.

(vi) Each Note issued upon transfer of, or in exchange for, another Note will bear each legend, if any, required by ‎Section 2.07.

(vii) Upon satisfaction of the requirements of this Indenture to effect a transfer or exchange of any Note, the Company will cause such transfer or exchange to be effected as soon as reasonably practicable but in no event later than the second (2nd) Business Day after the date of such satisfaction.

(viii) None of the Trustee, the Collateral Agent nor any Note Agent will have any responsibility or liability for any actions taken or not taken by the Depositary.

(B) Transfers and Exchanges of Global Notes.

(i) Subject to the immediately following sentence, no Global Note may be transferred or exchanged in whole except (x) by the Depositary to a nominee of the Depositary; (y) by a nominee of the Depositary to the Depositary or to another nominee of the Depositary; or (z) by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.  No Global Note (or any portion thereof) may be transferred to, or exchanged for, a Physical Note;  provided,  however, that a Global Note will be exchanged, pursuant to customary procedures, for one or more Physical Notes if:

(1) (x) the Depositary notifies the Company or the Trustee that the Depositary is unwilling or unable to continue as depositary for such Global Note or (y) the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act and, in each case, the Company fails to appoint a successor Depositary within ninety (90) days of such notice or cessation;

(2) an Event of Default has occurred and is continuing and a holder of a beneficial interest in such Global Note requests to exchange such Global Note or beneficial interest, as applicable, for one or more Physical Notes; or

(3) the Company, in its sole discretion, permits the exchange of any beneficial interest in such Global Note for one or more Physical Notes at the request of the owner of such beneficial interest.

(ii) Upon satisfaction of the requirements of this Indenture to effect a transfer or exchange of any Global Note (or any portion thereof):

(1) the Trustee will reflect any resulting decrease of the principal amount of such Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if such notation results in such Global Note having a principal amount of zero, the Company may (but is not required to) instruct

the Trustee to cancel such Global Note pursuant to Section 2.15);

(2) if required to effect such transfer or exchange, then the Trustee will reflect any resulting increase of the principal amount of any other Global Note by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such other Global Note;

(3) if required to effect such transfer or exchange, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Global Note bearing each legend, if any, required by ‎Section 2.07; and

(4) if such Global Note (or such portion thereof), or any beneficial interest therein, is to be exchanged for one or more Physical Notes, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that are in Authorized Denominations (not to exceed, in the aggregate, the principal amount of such Global Note to be so exchanged), are registered in such name(s) as the Depositary specifies (or as otherwise determined pursuant to customary procedures) and bear each legend, if any, required by ‎Section 2.07.

(iii) Each transfer or exchange of a beneficial interest in any Global Note will be made in accordance with the Depositary Procedures.

(C) Transfers and Exchanges of Physical Notes.

(i) Subject to this ‎Section 2.08, a Holder of a Physical Note may (x) transfer such Physical Note (or any portion thereof in an Authorized Denomination) to one or more other Person(s); (y) exchange such Physical Note (or any portion thereof in an Authorized Denomination) for one or more other Physical Notes in Authorized Denominations having an aggregate principal amount equal to the aggregate principal amount of the Physical Note (or portion thereof) to be so exchanged; and (z) if then permitted by the Depositary Procedures, transfer such Physical Note (or any portion thereof in an Authorized Denomination) in exchange for a beneficial interest in one or more Global Notes; provided,  however, that, to effect any such transfer or exchange, such Holder must surrender such Physical Note to be transferred or exchanged to the office of the Registrar, together with any endorsements or transfer instruments reasonably required by the Company, the Trustee or the Registrar.

(ii) Upon the satisfaction of the requirements of this Indenture to effect a transfer or exchange of any Physical Note (such Physical Note being referred to as the “old Physical Note” for purposes of this ‎Section 2.08(C)(ii)) of a Holder (or any portion of such old Physical Note in an Authorized Denomination):

(1) such old Physical Note will be promptly cancelled pursuant to Section 2.15;

(2) if such old Physical Note is to be transferred or exchanged only in part, then the Company will issue, execute and deliver, and the Trustee will authenticate,

in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such old Physical Note not to be transferred or exchanged; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by ‎Section 2.07;

(3) in the case of a transfer:

(a) to the Depositary or a nominee thereof that will hold its interest in such old Physical Note (or such portion thereof) to be so transferred in the form of one or more Global Notes, the Trustee will reflect an increase of the principal amount of one or more existing Global Notes by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note(s), which increase(s) are in Authorized Denominations and aggregate to the principal amount to be so transferred, and which Global Note(s) bear each legend, if any, required by ‎Section 2.07;  provided,  however, that if such transfer cannot be so effected by notation on one or more existing Global Notes (whether because no Global Notes bearing each legend, if any, required by ‎Section 2.07 then exist, because any such increase will result in any Global Note having an aggregate principal amount exceeding the maximum aggregate principal amount permitted by the Depositary or otherwise), then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Global Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; and (y) bear each legend, if any, required by ‎Section 2.07; and

(b) to a transferee that will hold its interest in such old Physical Note (or such portion thereof) to be so transferred in the form of one or more Physical Notes, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so transferred; (y) are registered in the name of such transferee; and (z) bear each legend, if any, required by ‎Section 2.07; and

(4) in the case of an exchange, the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount to be so exchanged; (y) are registered in the name of the Person to whom such old Physical Note was registered; and (z) bear each legend, if any, required by ‎Section 2.07.

(D) Transfers of Notes Subject to Redemption, Repurchase or Conversion.  Notwithstanding anything to the contrary in this Indenture or the Notes, the Company, the Trustee and the Registrar will not be required to register the transfer of or exchange any Note that (i) has been surrendered for conversion, except to the extent that any portion of such Note is not subject

to conversion; (ii) is subject to a Fundamental Change Repurchase Notice or Optional Repurchase Notice validly delivered, and not withdrawn, pursuant to Section ‎4.02(F) or ‎4.03(E), respectively, except to the extent that any portion of such Note is not subject to such notice or the Company fails to pay the applicable Fundamental Change Repurchase Price or Optional Repurchase Price, as applicable, when due; or (iii) has been selected for Redemption pursuant to a Redemption Notice, except to the extent that any portion of such Note is not subject to Redemption or the Company fails to pay the applicable Redemption Price when due.

Section 2.09. Exchange and Cancellation of Notes to Be Converted, Redeemed or Repurchased.

(A) Partial Conversions, Redemptions and Repurchases of Physical Notes.  If only a portion of a Physical Note of a Holder is to be converted pursuant to ‎Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, Optional Repurchase or Redemption, then, as soon as reasonably practicable after such Physical Note is surrendered for such conversion, Redemption or repurchase, the Company will cause such Physical Note to be exchanged, pursuant and subject to ‎Section 2.08(C), for (i) one or more Physical Notes that are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted, redeemed or repurchased, as applicable, and deliver such Physical Note(s) to such Holder; and (ii) a Physical Note having a principal amount equal to the principal amount to be so converted, redeemed or repurchased, as applicable, which Physical Note will be converted, redeemed or repurchased, as applicable, pursuant to the terms of this Indenture; provided,  however, that the Physical Note referred to in this clause (ii) need not be issued at any time after which such principal amount subject to such conversion, Redemption or repurchase, as applicable, is deemed to cease to be outstanding pursuant to ‎Section 2.13.

(B) Cancellation of Converted, Redeemed and Repurchased Notes.

(i) Physical Notes.  If a Physical Note (or any portion thereof that has not theretofore been exchanged pursuant to ‎Section 2.09(A)) of a Holder is to be converted pursuant to ‎Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change, Optional Repurchase or Redemption, then, promptly after the later of the time such Physical Note (or such portion) is deemed to cease to be outstanding pursuant to ‎Section 2.13 and the time such Physical Note is surrendered for such conversion or repurchase, as applicable, (1) such Physical Note will be cancelled pursuant to Section 2.15; and (2) in the case of a partial conversion, Redemption or repurchase, the Company will issue, execute and deliver to such Holder, and the Trustee will authenticate, in each case in accordance with Section 2.02, one or more Physical Notes that (x) are in Authorized Denominations and have an aggregate principal amount equal to the principal amount of such Physical Note that is not to be so converted, redeemed or repurchased; (y) are registered in the name of such Holder; and (z) bear each legend, if any, required by ‎Section 2.07.

(ii) Global Notes.  If a Global Note (or any portion thereof) is to be converted pursuant to ‎Section 4.04 or repurchased pursuant to a Repurchase Upon Fundamental Change, Optional Repurchase or Redemption, then, promptly after the time such Note (or such portion) is deemed to cease to be outstanding pursuant to ‎Section 2.13, the Trustee

will reflect a decrease of the principal amount of such Global Note in an amount equal to the principal amount of such Global Note to be so converted, redeemed or repurchased, as applicable, by notation on the “Schedule of Exchanges of Interests in the Global Note” forming part of such Global Note (and, if the principal amount of such Global Note is zero following such notation, cancel such Global Note pursuant to Section 2.15).

(C) Holder of Record of Conversion Shares.  The Person in whose name any share of Common Stock is issuable upon conversion of any Note will be deemed to become the holder of record of such share as of the Close of Business on the Conversion Date for such conversion.

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

(E) Conversion Agent to Notify Company of Conversions.  If any Note is submitted for conversion to the Conversion Agent or the Conversion Agent receives any notice of conversion with respect to a Note, then the Conversion Agent will promptly notify the Company and the Trustee of such occurrence, together with any other information reasonably requested by the Company, and will cooperate with the Company to determine the Conversion Date for such Note.

Section 5.03. Settlement upon Conversion.

(A) Conversion Consideration.

(i) Generally.  Subject to ‎Section 5.03(A)(ii) and ‎Section 5.03(A)(iii), the type and amount of consideration (the “Conversion Consideration”) due in respect of any Note (or portion thereof) to be converted will be (a) a number of shares of Common Stock, per

$1,000 principal amount of such Note to be converted, equal to the Conversion Rate in effect on the Conversion Date for such conversion; and (b) a cash amount equal to the sum of the following: 

(1) unpaid interest that has accrued on such Note (or such portion thereof) to, but excluding, the date the Company settles such conversion (unless such Conversion Date is after a Regular Record Date and before the next Interest Payment Date, in which case (y) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such conversion, to receive, on or, at the Company’s election, before such Interest Payment Date, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Conversion Date is before such Interest Payment Date); and (z) the Company will not pay any separate cash amount pursuant to this ‎Section 5.03(A)(i)(1) for interest as part of the consideration due upon such conversion); and

(2) the Interest Make-Whole for such conversion.

(ii) Cash in Lieu of Fractional Shares.  If the number of shares of Common Stock deliverable pursuant to ‎Section 5.03(A)(i) upon conversion of any Note is not a whole number, then such number will be rounded down to the nearest whole number and the Company will deliver, in addition to the other consideration due upon such conversion, cash in lieu of the related fractional share in an amount equal to the product of (1) such fraction and (2) the Daily VWAP per share of Common Stock on the Conversion Date for such conversion (or, if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day).

(iii) Conversion of Multiple Notes by a Single Holder.  If a Holder converts more than one (1) Note on a single Conversion Date, then the Conversion Consideration due in respect of such conversion will (in the case of any Global Note, to the extent permitted by, and practicable under, the Depositary Procedures) be computed based on the total principal amount of Notes converted on such Conversion Date by such Holder.

(B) Delivery of the Conversion Consideration.  Except as set forth in Sections ‎5.06(A) and ‎5.06(C) or in the proviso to this sentence, the Company will pay or deliver, as applicable, the Conversion Consideration due upon the conversion of any Note to the Holder on or before the second (2nd) Business Day immediately after the Conversion Date for such conversion.

(C) Accrued Interest Notwithstanding Conversion.  Without limiting the Company’s obligation to pay interest pursuant to ‎Section 5.03(A)(i), if a Holder converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on such Note.

Section 5.04. Company’s Mandatory Conversion Option.

(A) Mandatory Conversion.  Subject to ‎Section 5.04(D), if, at any time prior to the Maturity Date, the Daily VWAP per share of the Common Stock equals or exceeds one hundred and twenty-one  (121%) of the Conversion Price on each of at least twenty (20) VWAP Trading

Days, whether or not consecutive, during any thirty (30) consecutive VWAP Trading Day period commencing on or after the Issue Date, then the Company will have the right (the “Company Mandatory Conversion Right”), exercisable at the Company’s election, to cause all (and not less than all) Notes then outstanding to be automatically converted (any such conversion, a “Mandatory Conversion”).    

(B) Mandatory Conversion Notice.  To exercise the Company Mandatory Conversion Right, the Company will send notice of the Company’s election (a “Mandatory Conversion Notice”) to Holders, the Trustee and the Conversion Agent no later than the fifth (5th) Business Day after the last VWAP Trading Day of such 30 consecutive VWAP Trading Day period.

(i) that the Notes have been called for Mandatory Conversion, briefly describing the Company Mandatory Conversion Right under this Indenture;

(ii) the Mandatory Conversion Date;

(iii) the current Conversion Rate;

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

(v) the CUSIP and ISIN numbers, if any, of the Notes.

(C) Effect of Mandatory Conversion; Mandatory Conversion Date.  If the Company exercises the Company Mandatory Conversion Right in accordance with this ‎Section 5.04, then a Conversion Date will automatically, and without the need for any action on the part of any Holder, the Trustee or the Conversion Agent, be deemed to occur, with respect to each Note then outstanding, on the Mandatory Conversion Date.  The Mandatory Conversion Date will be a Business Day of the Company’s choosing that is no more than thirty (30), nor less than ten (10), Business Days after the Company sends the Mandatory Conversion Notice.

(D) Mandatory Conversion Prohibited in Certain Circumstances.  Notwithstanding anything to the contrary in this ‎Section 5.04, the Company may not exercise its Company Mandatory Conversion Right at any time during the period beginning on the effective date of a Fundamental Change or Make-Whole Fundamental Change and ending on the thirty-fifth (35th) Trading Day after such effective date (or, in the case of a Fundamental Change, ending on the related Fundamental Change Repurchase Date).  In addition, notwithstanding anything to the contrary in this ‎Section 5.04, the Company may not exercise its Company Mandatory Conversion Right unless all of the following conditions (collectively, the “Equity Conditions”) are satisfied on each day from, and including, the date the Company sends the Mandatory Conversion Notice to, and including, the Mandatory Conversion Date:

(i) either (x) all shares of the Common Stock issuable upon Mandatory Conversion will be eligible for resale, by a person that is not an Affiliate of the Company, without registration under any applicable federal or state securities laws; or (y) a shelf registration statement registering the resale of the shares of Common Stock issuable upon

conversion of the Notes is effective under the Securities Act and available for use by the persons to whom such shares are to be issued, and the Company expects such shelf registration statement to remain effective and so available for use from the date the Company sends the Mandatory Conversion Notice through the date that is thirty (30) calendar days following such Mandatory Conversion Date;

(ii) the Common Stock is listed on any Eligible Market and has not been suspended from trading on such Eligible Market (other than suspensions of not more than two (2) Trading Days and occurring before the applicable date of determination due to business announcements by the Company);

(iii) the delisting or suspension of the Common Stock is not pending and has not been threatened in writing by the applicable Eligible Market, and the Company is not then in violation of the then effective minimum listing maintenance requirements of such Eligible Market;

(iv) all shares of Common Stock issuable upon Mandatory Conversion may be issued in full without violating the listing rules of The Nasdaq Global Market or any other applicable Eligible Market on which the Common Stock is then listed or trading; and

(v) the Company has not defaulted on its obligation to convert any Note before the date the Company sends the Mandatory Conversion Notice, and no Default or Event of Default has occurred and is continuing.

Section 5.05. Reserve and Status of Common Stock Issued upon Conversion.

(A) Stock Reserve.  At all times from and after the Issue Date,  when any Notes are outstanding, the Company will reserve, out of its authorized but unissued and unreserved shares of Common Stock, a number of shares of Common Stock sufficient to permit the conversion of all then-outstanding Notes, assuming the Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to ‎Section 5.08.

(B) Status of Conversion Shares; Listing.  Each Conversion Share delivered upon conversion of any Note will be a newly issued or treasury share and will be duly and validly issued, fully paid, non-assessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder of such Note or the Person to whom such Conversion Share will be delivered).  If the Common Stock is then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will cause each Conversion Share, when delivered upon conversion of any Note, to be admitted for listing on such exchange or quotation on such system.

Section 5.06. Adjustments to the Conversion Rate.

(A) Events Requiring an Adjustment to the Conversion Rate.  The Conversion Rate will be adjusted, without duplication, from time to time as follows:

(i) Stock Dividends, Splits and Combinations.  If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common Stock (in each case excluding an issuance solely pursuant to a Common Stock Change Event, as to which ‎Section 5.09 will apply), then the Conversion Rate will be adjusted based on the following formula:

(ii) Rights, Options and Warrants.  If the Company distributes, to all or substantially all holders of Common Stock, rights, options or warrants (other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which the

provisions set forth in Sections ‎5.06(A)(iii)(1) and ‎5.06(E) will apply) entitling such holders, for a period of not more than forty-five (45) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion Rate will be increased based on the following formula:

(iii) Spin-Offs and Other Distributed Property.

(1) Distributions Other than Spin-Offs.  If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding:

(2) Spin-Offs.  If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity interest, of or relating to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common Stock (other than solely pursuant to a Common Stock Change Event, as to which ‎Section 5.09 will apply), and such Capital Stock or equity interest is listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), then the Conversion Rate will be increased based on the following formula:

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

(v) Tender Offers or Exchange Offers.  If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock, and the value (determined as of the Expiration Time by the Board of Directors) of the cash and other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Price per share of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased based on the following formula:

(B) No Adjustments in Certain Cases.

(i) Where Holders Participate in the Transaction or Event Without Conversion.  Notwithstanding anything to the contrary in ‎Section 5.06(A), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event otherwise requiring an adjustment pursuant to ‎Section 5.06(A) (other than a stock split or combination of the type set forth in ‎Section 5.06(A)(i) or a tender or exchange offer of the type set forth in ‎Section 5.06(A)(v)) if each Holder participates, at the same time and on the same terms as holders of Common Stock, and solely by virtue of being a Holder of Notes, in such transaction or event without having to convert such Holder’s Notes and as if such Holder held a number of shares of Common Stock equal to the product of (i) the Conversion Rate in effect on the related record date, effective date or Expiration Date, as applicable; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such date.

(ii) Certain Events.  The Company will not be required to adjust the Conversion Rate except as provided in ‎Section 5.06 or ‎Section 5.08.  Without limiting the foregoing,

the Company will not be obligated to adjust the Conversion Rate on account of:

(1) except as otherwise provided in ‎Section 5.06, the sale of shares of Common Stock for a purchase price that is less than the market price per share of Common Stock or less than the Conversion Price;

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

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

(4) the issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or exchangeable security of the Company not described in clause ‎(3) above and outstanding as of the Issue Date;

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

(6) accrued and unpaid interest on the Notes.

(C) Adjustments Not Yet Effective.  Notwithstanding anything to the contrary in this Indenture or the Notes, if:

(i) a Note is to be converted;

(ii) the record date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to ‎Section 5.06(A) has occurred on or before the Conversion Date for such conversion, but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date;

(iii) the Conversion Consideration due upon such conversion includes any whole shares of Common Stock; and

(iv) such shares are not entitled to participate in such event (because they were not held on the related record date or otherwise),

(D) Conversion Rate Adjustments where Converting Holders Participate in the Relevant Transaction or Event.  Notwithstanding anything to the contrary in this Indenture or the Notes, if:

(i) a Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to ‎Section 5.06(A);

(ii) a Note is to be converted;

(iii) the Conversion Date for such conversion occurs on or after such Ex-Dividend Date and on or before the related record date;

(iv) the Conversion Consideration due upon such conversion includes any whole shares of Common Stock based on a Conversion Rate that is adjusted for such dividend or distribution;  and

(v) such shares would be entitled to participate in such dividend or distribution (including pursuant to ‎Section 5.02(C)),

(E) Stockholder Rights Plans.  If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of such conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive, in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under this Indenture upon such conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such time, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to ‎Section 5.06(A)(iii)(1) on account of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section to all holders of the Common Stock, subject to readjustment in accordance with such Section if such rights expire, terminate or are redeemed.

(F) Limitation on Effecting Transactions Resulting in Certain Adjustments.  The Company will not engage in or be a party to any transaction or event that would require the Conversion Rate to be adjusted pursuant to ‎Section 5.06(A) or ‎Section 5.08 to an amount that would result in the Conversion Price per share of Common Stock being less than the par value per share of Common Stock.

(G) Equitable Adjustments to Prices.  Whenever any provision of this Indenture requires the Company to calculate the average of the Last Reported Sale Prices or Daily VWAPs, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to the Conversion Rate), the Company will make proportionate adjustments, if any, to such calculations to account for any adjustment to the Conversion Rate pursuant to ‎Section 5.06(A)(i) that becomes effective, or any event requiring such an adjustment to the Conversion Rate where the Ex-Dividend Date or effective date, as applicable, of such event occurs, at any time during such period.

(H) Calculation of Number of Outstanding Shares of Common Stock.  For purposes of ‎Section 5.06(A),  the number of shares of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock; and (ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays any dividend or makes any distribution on shares of Common Stock held in its treasury).

(I) Calculations.  All calculations with respect to the Conversion Rate and adjustments thereto will be made to the nearest 1/10,000th of a share of Common Stock (with 5/100,000ths rounded upward to the nearest 1/10,000th), as applicable.

(J) Notice of Conversion Rate Adjustments.  Upon the effectiveness of any adjustment to the Conversion Rate pursuant to ‎Section 5.06(A), the Company will promptly send notice to the Holders, the Trustee and the Conversion Agent containing (i) a brief description of the transaction or other event on account of which such adjustment was made; (ii) the Conversion Rate in effect immediately after such adjustment; and (iii) the effective time of such adjustment.

Section 5.07. Voluntary Adjustments.

(A) Generally.  To the extent permitted by law and applicable stock exchange rules, the Company, from time to time, may (but is not required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is either (x) in the best interest of the Company; or (y) advisable to avoid or diminish any income tax imposed on holders of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) of Common Stock or any similar event; (ii) such increase is in effect for a period of at least twenty (20) Business Days; and (iii) such increase is irrevocable during such period.

(B) Notice of Voluntary Increases.  If the Board of Directors determines to increase the Conversion Rate pursuant to this ‎Section 5.07, then, at least fifteen (15) Business Days before such increase, the Company will send notice to each Holder, the Trustee and the Conversion Agent of such increase, the amount thereof and the period during which such increase will be in effect.

Section 5.08. Adjustments to the Conversion Rate in Connection with a Make-Whole Fundamental Change.

(A) Generally.  If a Make-Whole Fundamental Change occurs on or before November 1, 2022 and the Conversion Date for the conversion of a Note occurs during the related Make-Whole Fundamental Change Conversion Period, then, subject to this ‎Section 5.08, the Conversion Rate applicable to such conversion will be increased by a number of shares (the “Additional Shares”) set forth in the table below corresponding (after interpolation as provided in, and subject to, the provisions below) to the effective date and the Stock Price of such Make-Whole Fundamental Change:

Stock Price

Effective Date

$2.00

November 14, 2019.....

November 1, 2020.......

November 1, 2021.......

November 1, 2022.......

(i) if such Stock Price is between two Stock Prices in the table above or the effective date is between two effective dates in the table above, then the number of Additional Shares will be determined by a straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices in the table and the earlier and later effective dates in the table above, as applicable, based on a 365- or 366-day year, as applicable; and

(ii) if the Stock Price is greater than $2.00 (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above are adjusted pursuant to ‎Section 5.08(B)), or less than $1.08 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the Conversion Rate.

(B) Adjustment of Stock Prices and Additional Shares.  The Stock Prices in the first row (i.e., the column headers) of the table set forth in ‎Section 5.08(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted as a result of the operation of ‎Section 5.06(A).  The numbers of Additional Shares in the table set forth in ‎Section 5.08(A) will be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Rate is adjusted pursuant to ‎Section 5.08(A).

(C) Notice of the Occurrence of a Make-Whole Fundamental Change.  If a Make-Whole Fundamental Change occurs, then, promptly and in no event later than five (5) Business Days immediately after the effective date of such Make-Whole Fundamental Change, the Company will notify the Holders and the Trustee of the occurrence of such Make-Whole Fundamental Change and of such effective date, briefly stating the circumstances under which the Conversion Rate will be increased pursuant to this ‎Section 5.08 in connection with such Make-Whole Fundamental Change.

(D) Settlement of Cash Make-Whole Fundamental Changes.  For the avoidance of doubt, if holders of Common Stock receive solely cash in a Make-Whole Fundamental Change, then, pursuant to ‎Section 5.09, conversions of Notes will thereafter be settled no later than the third (3rd) Business Day after the relevant Conversion Date.

Section 5.09. Effect of Common Stock Change Event.

(A) Generally.  If there occurs any:

(i) recapitalization, reclassification or change of the Common Stock (other than (x) changes solely resulting from a subdivision or combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value or (z) stock splits and stock combinations that do not involve the issuance of any other series or class of securities);

(ii) consolidation, merger, combination or binding or statutory share exchange involving the Company;

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

(iv) other similar event,

(B) Notice of Common Stock Change Events.  The Company will provide notice of each Common Stock Change Event to Holders, the Trustee and the Conversion Agent no later than the effective date of such Common Stock Change Event.

(C) Compliance Covenant.  The Company will not become a party to any Common Stock Change Event unless its terms are consistent with this ‎Section 5.09.

Section 5.10. Responsibility of the Trustee.

Section 5.11. Limits Upon Issuance of Shares of Common Stock Upon Conversion.

(A) Notwithstanding anything to the contrary herein, no Person will be entitled to receive any shares of Common Stock otherwise deliverable upon conversion of the Notes to the extent, but only to the extent, that such receipt would cause such Person to become, directly or indirectly, a Beneficial Owner of more than 9.99% of the shares of the Common Stock outstanding at such time (such restriction, the “General Beneficial Ownership Limit”). For purposes of this ‎Section 5.11 only, a Person will be deemed the “Beneficial Owner” of and will be deemed to beneficially own any shares of Common Stock that such Person or any of such person’s Affiliates (as defined in Rule 12b-2 under the Exchange Act) or associates (as defined in Rule 12b-2 under the Exchange Act) is deemed to beneficially own, together with any shares of Common Stock beneficially owned by any other persons whose beneficial ownership would be aggregated with such Person for purposes of Section 13(d) of the Exchange Act. Subject to the following proviso, for purposes of the this ‎Section 5.11 only, beneficial ownership will be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder as in effect on the Issue Date; provided that the number of shares of Common Stock beneficially owned by such Person and its Affiliates and associates and any other persons whose beneficial ownership would be aggregated with such Person for purposes of Section 13(d) of the Exchange Act will include the number of shares of Common Stock issuable upon exercise or conversion of any of the Company’s securities or rights to acquire the Common Stock, whether or not such securities or rights are currently exercisable or convertible or are exercisable or convertible only after the passage of time (including the number of shares of Common Stock issuable upon conversion of the Notes in respect of which the beneficial ownership determination is being made), but will exclude the number of shares of Common Stock that would be issuable upon (A) conversion of the remaining, unconverted portion of any Notes beneficially owned by such Person or any of its Affiliates or associates and any other persons whose beneficial ownership would be aggregated with such Person for purposes of Section 13(d) of the Exchange Act and (B) exercise or conversion of the unexercised or unconverted portion of any of the Company’s other securities subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Person or any of its Affiliates or associates and any other persons whose beneficial ownership would be aggregated with such Person for purposes of Section 13(d) of the Exchange Act. For the avoidance of doubt, the term “Beneficial Owner” as used in this ‎Section 5.11 will not include (i) with respect to any Global Note, the nominee of the Depositary or any Person having an account with the Depositary or its nominee or (ii) with respect to any certificated Note, the Holder of such certificated Note unless, in each case, such nominee, account holder or Holder will also be a Beneficial Owner of such Note.

(B) In addition, a Holder at its option may elect a beneficial ownership limit as to such Holder (but not as to any other Holder) that is less than or equal to the general beneficial ownership limit then applicable to the Holders in general upon written notice delivered to the Company prior to the issuance of the Notes or, if thereafter, at least 61 days prior to the date of effectiveness of such lower beneficial ownership limit, specifying the percentage of shares of Common Stock for the beneficial ownership limit that will apply to such Holder (such beneficial ownership limit, a “Holder Beneficial Ownership Limit” and together with the general beneficial ownership limit, the “Beneficial Ownership Limits”). Written notices sent by Holders electing a Holder Beneficial

Ownership Limit pursuant to this ‎Section 5.11(B) received prior to the Issue Date and the issuance of the Notes are listed on Schedule 1 to this Indenture.

(C) Any purported delivery of shares of Common Stock upon conversion of the Notes will be void and have no effect to the extent, but only to the extent, that such delivery would result in any Person becoming the Beneficial Owner of shares of Common Stock outstanding at such time in excess of the Beneficial Ownership Limits applicable to such Person.

(D) Unless the Company has waived the General Beneficial Ownership Limit as set forth in ‎Section 5.11(F) and there is no Holder Beneficial Ownership Limit applicable to a Holder, when such Holder tenders Notes for conversion, that Holder must provide a certification to the Company as to whether the Person (or Persons) receiving shares of Common Stock upon conversion is, or would, as a result of such conversion, become the beneficial owner of shares of Common Stock outstanding at such time in excess of any beneficial ownership limit then applicable to such Person (or Persons).

(E) If any delivery of shares of Common Stock otherwise owed to any Person (or persons) upon conversion of the Notes is not made, in whole or in part, as a result of the applicable Beneficial Ownership Limits, the Company’s obligation to make such delivery will not be extinguished and, such Holder may either:
