Item 1.01 Entry Into or Amendment of aMaterial Definitive Agreement

Indenture

On May 7, 2026, ProPetro Holding Corp. (the “Company”), issued $690 million aggregate principal amount of its 0.00% Convertible Senior Notes due 2031 (the “Notes”), which included the exercise in full of the Initial Purchasers’ (as defined below) option to purchase up to an additional $90 million principal amount of Notes. The Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of May 7, 2026, between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”).

The Notes are the Company’s senior, unsecured obligations and are (i) senior in right of payment to the Company’s indebtedness that is expressly subordinated in right of payment to the Notes; (ii) equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; (iii) effectively junior to the Company’s secured indebtedness, to the extent of the value of the assets securing that indebtedness; and (iv) structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries.

The Notes will not bear regular interest, and the principal amount of the Notes will not accrete. The Notes will mature on November 15, 2031, unless earlier converted, redeemed or repurchased. Before August 15, 2031, noteholders will have the right to convert their Notes only in certain circumstances and during specified periods. From and after August 15, 2031, noteholders may convert their Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, shares of the Company’s common stock, par value $0.001 (the “Common Stock”), or a combination of cash and the Company’s Common Stock, at its election. The initial conversion rate is 43.1616 shares of Common Stock per $1,000 principal amount of Notes, which represents an initial conversion price of approximately $23.17 per share of Common Stock and a premium of approximately 37.5% over the last reported sale price of $16.85 per share of the Company’s Common Stock on the New York Stock Exchange on May 4, 2026. The conversion rate and conversion price will be subject to adjustment upon the occurrence of certain events.

The Notes are redeemable, in whole or in part (subject to certain limitations), at the Company’s option at any time, and from time to time, on or after May 15, 2029 and prior to the 45th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid special interest and additional interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Common Stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption. However, the Company may not redeem less than all of the outstanding Notes unless at least $150.0 million aggregate principal amount of Notes are outstanding and not subject to redemption as of, and after giving effect to, delivery of the relevant notice of redemption. If a fundamental change (as defined in the Indenture) occurs, then, subject to limited exceptions, noteholders may require the Company to repurchase the Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid special interest and additional interest, if any, to, but excluding any repurchase date. In addition, if the effective date of a “make-whole fundamental change” (as defined in the Indenture) occurs prior to the maturity date of the Notes or if the Company gives a notice of redemption with respect to any or all of the Notes, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such make-whole fundamental change or convert its Notes called for redemption (or deemed called for redemption) in connection with such notice of redemption, as the case may be.

The Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) a default in any payment of interest on, or payment of principal of, the Notes when due and payable (which, in the case of a default in the payment of special interest or additional interest on the Notes, will be subject to a 30-day cure period); (ii) a default in the Company’s obligation to convert a Note upon the exercise of the conversion right with respect thereto, if such default continues for five business days; (iii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iv) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person (other than to one or more of the Company’s direct or indirect wholly owned subsidiaries); (v) a default by the Company in its other obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (vi) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $50 million; and (vii) certain events of bankruptcy, insolvency and reorganization with respect to the Company or any of its significant subsidiaries.

If an Event of Default involving bankruptcy, insolvency and reorganization with respect to the Company occurs, then the principal amount of, and all accrued and unpaid interest, if any, on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest, if any, on, all of the Notes then outstanding to become due and payable immediately. Notwithstanding anything to the contrary described above, the Company may elect that the sole remedy for any Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists, for the first 365 days after the occurrence of such Event of Default, exclusively of the right of the noteholders to receive special interest on the Notes. If the Company has made such an election, then on the 366th day after such Event of Default (if such Event of Default is not cured or validly waived in accordance with the Indenture prior to such 366th day), such special interest will cease to accrue and the Notes will be subject to acceleration. In the event the Company does not make such an election, or the Company has made such election but does not pay the additional interest when due, the Notes will be immediately subject to acceleration.

The above description of the Indenture and the Notes is a summary and is not complete. A copy of the Indenture and the form of the certificate representing the Notes are filed as Exhibits 4.1 and 4.2, respectively, to this Current Report on Form 8-K, and the above summary is qualified in its entirety by reference to the terms of the Indenture and the Note set forth in such exhibits.

Capped Call Transactions

On May 4, 2026, concurrently with the pricing of the Notes, and on May 5, 2026, in connection with the exercise in full by the Initial Purchasers of their option to purchase additional Notes, the Company entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with an affiliate of one of the Initial Purchasers and certain other financial institutions (the “Option Counterparties”). The Capped Call Transactions initially cover, subject to anti-dilution adjustments substantially similar to those applicable to the Notes, the number of shares of the Company’s Common Stock that initially underlie the Notes, and are expected generally to reduce potential dilution to the Company’s Common Stock upon any conversion of Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted Notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the Capped Call Transactions will initially be approximately $29.49 per share (subject to adjustment under the terms of the Capped Call Transactions), which represents a premium of approximately 75.0% over the last reported sale price of $16.85 per share of the Company’s Common Stock on May 4, 2026. The cost of the Capped Call Transactions was approximately $36.8 million.

The Capped Call Transactions are separate transactions, each entered into between the Company and the applicable Option Counterparty, and are not part of the terms of the Notes and will not change any holder’s rights under the Notes or the Indenture. Holders of the Notes will not have any rights with respect to the Capped Call Transactions.

The above description of the Capped Call Transactions is a summary and is not complete. A copy of the form of confirmation for the Capped Call Transactions is filed as Exhibit 10.1 to this Current Report on Form 8-K, and the above summary is qualified in its entirety by reference to the terms of the form of confirmation set forth in such exhibit.

Amended and Restated Credit Agreement

On May 4, 2026, the Company entered into a fourth amendment (the “Amendment”) to its amended and restated credit agreement (the “ABL Credit Facility”). The Amendment extends the stated maturity date of the revolving credit commitments to May 4, 2031, subject to a springing maturity date ninety-one (91) days before the maturity date of certain long-term indebtedness (if applicable). The Amendment increases the aggregate revolving credit commitments (and the maximum revolver amount) to $350 million, with an uncommitted accordion in an aggregate amount not to exceed the greater of (a) $150 million and (b) the amount, if any, by which the borrowing base exceeds the commitments outstanding under the ABL Credit Facility, subject to usual and customary terms and conditions.

The Amendment adds certain power generation equipment as a new component of the borrowing base under the ABL Credit Facility. Subject to additional limitations set forth in the ABL Credit Facility, the portion of the borrowing base attributable to such equipment shall not exceed 35% of the borrowing base in the aggregate. The advance rates for such equipment are equal to the lesser of (i) 90% of the book value of such equipment and (ii) 80% of the net orderly liquidation value of such equipment. The Amendment also increases the amount of leverage-ratio-based indebtedness that can be incurred, increases the amount of capital lease and purchase money debt that can be incurred, and includes a new $690 million basket for the incurrence of convertible indebtedness. The applicable interest rate margins for borrowings under the ABL Credit Facility range from 1.50% to 2.00% per annum for term SOFR borrowings, based on average historic availability under the ABL Credit Facility. The applicable unused line fee on the unutilized portion of the commitments in respect of the ABL Credit Facility shall accrue at either 0.375% or 0.25% per annum, based on average historic revolver outstandings.

The above description of the Amendment is a summary and is not complete. A copy of the Amendment is filed as Exhibit 10.2 to this Current Report on Form 8-K, and the above summary is qualified in its entirety by reference to the terms of the Amendment set forth in such exhibit.

Item 2.03 Creation of a Direct FinancialObligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information contained in Item 1.01 of this Current Report on Form 8-K relating to the Indenture under the heading “Indenture” and the Amendment under the heading “Amended and Restated Credit Agreement” is incorporated into this Item 2.03 by reference.

Item 3.02 Unregistered Sales of EquitySecurities.

The disclosure set forth in Item 1.01 above under the caption “Indenture” is incorporated by reference into this Item 3.02. The Notes were issued to the Initial Purchasers in reliance upon Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), in transactions not involving any public offering. The Notes were resold by the Initial Purchasers to persons whom the Initial Purchasers reasonably believe are qualified institutional buyers pursuant to Rule 144A under the Securities Act. Any shares of the Company’s Common Stock that may be issued upon conversion of the Notes will be issued in reliance upon Section 3(a)(9) of the Securities Act as involving an exchange by the Company exclusively with its security holders. Initially, a maximum of 40,949,499 shares of the Company’s Common Stock may be issued upon conversion of the Notes, based on the initial maximum conversion rate of 59.3471 shares of Common Stock per $1,000 principal amount of Notes, which is subject to customary anti-dilution adjustment provisions.

Item8.01 Other Events

On May 4, 2026, the Company issued a press release announcing the pricing of the Notes. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

Purchase Agreement

On May 4, 2026, the Company entered into a purchase agreement (the “Purchase Agreement”) with Goldman Sachs & Co. LLC and Barclays Capital Inc., as representatives of the several initial purchasers named therein (the “Initial Purchasers”), in connection with the offering of the Notes (the “Notes Offering”).

The Notes were issued and sold to the Initial Purchasers pursuant to an exemption from the registration requirements of the Securities Act in reliance upon Section 4(a)(2) of the Securities Act. The Initial Purchasers resold the Notes only to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A under the Securities Act. The Notes have not been, and will not be, registered under the Securities Act, or any state securities laws, and, unless so registered, may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The Notes Offering closed on May 7, 2026.

The Purchase Agreement contains customary representations, warranties and agreements by the Company and customary conditions to closing, obligations of the parties and termination provisions. Additionally, the Company has agreed to indemnify the Initial Purchasers against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the Initial Purchasers may be required to make because of any of those liabilities.

The terms contained in the Notes constitute part of this Indenture, and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, agree to such terms and to be bound thereby; provided, however, that, to the extent that any provision of any Note conflicts with the provisions of this Indenture, the provisions of this Indenture will control for purposes of this Indenture and such Note.

**Section 2.02.**Execution,Authentication and Delivery.

(A)          DueExecution by the Company. At least one (1) duly authorized Officer will sign the Notes on behalf of the Company by manual, electronic or facsimile signature. A Note’s validity will not be affected by the failure of any Officer whose signature is on any Note to hold, at the time such Note is authenticated, the same or any other office at the Company.

(B)          Authenticationby the Trustee and Delivery.

(i)            No Note will be valid until it is authenticated by the Trustee. A Note will be deemed to be duly authenticated only when an authorized signatory of the Trustee (or a duly appointed authenticating agent) manually signs the certificate of authentication of such Note.

(ii)           The Trustee will cause an authorized signatory of the Trustee (or a duly appointed authenticating agent) to manually sign the certificate of authentication of a Note only if (1) the Company delivers such Note to the Trustee; (2) such Note is executed by the Company in accordance with Section 2.02(A); and (3) the Company delivers a Company Order to the Trustee that (a) requests the Trustee to authenticate such Note; and (b) sets forth the name of the Holder of such Note and the date as of which such Note is to be authenticated. If such Company Order also requests the Trustee to deliver such Note to any Holder or to the Depositary, then the Trustee will promptly deliver such Note in accordance with such Company Order.

(iii)          The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. A duly appointed authenticating agent may authenticate Notes whenever the Trustee may do so under this Indenture, and a Note authenticated as provided in this Indenture by such an agent will be deemed, for purposes of this Indenture, to be authenticated by the Trustee. Each duly appointed authenticating agent will have the same rights to deal with the Company as the Trustee would have if it were performing the duties that the authenticating agent was validly appointed to undertake.

**Section 2.03.**InitialNotes and Additional Notes.

(A)          InitialNotes. On the Issue Date, there will be originally issued six hundred ninety million dollars ($690,000,000) aggregate principal amount of Notes, subject to the provisions of this Indenture (including Section 2.02). Notes issued pursuant to this Section 2.03(A), and any Notes issued in exchange therefor or in substitution thereof, are referred to in this Indenture as the “Initial Notes.”

(B)          AdditionalNotes. Without the consent of any Holder, the Company may, subject to the provisions of this Indenture (including Section 2.02), originally issue additional Notes with the same terms as the Initial Notes (except, to the extent applicable, with respect to the Last Original Issue Date of such additional Notes), which additional Notes will, subject to the foregoing, be considered to be part of the same series of, and rank equally and ratably with all other, Notes issued under this Indenture; provided, however, that such additional Notes must be identified by a separate CUSIP number or by no CUSIP number if they are not fungible, for U.S. federal income tax or federal securities laws purposes, with other Notes issued under this Indenture. Any resale of Notes that the Company repurchases as described and subject to the conditions set forth in this Indenture will be deemed to be an “issuance” of Notes for purposes of the foregoing.

**Section 2.04.**Methodof Payment.

(A)          GlobalNotes. 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 or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest, if any, 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)          PhysicalNotes. 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 or repurchase on a Fundamental Change Repurchase Date or otherwise) of, interest, if any, 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 a U.S. dollar account of such Holder within the contiguous 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 Special Interest or Additional Interest, if any, due on an Interest Payment Date, the immediately preceding Interest 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 2.05.**NoRegular Interest; Accrual and Payment of Special Interest and Additional Interest; Defaulted Amounts; When Payment Date is Not a BusinessDay.

(A)          NoRegular Interest; Accrual and Payment of Special Interest and Additional Interest. The Notes will not bear regular interest, and the principal amount of the Notes will not accrete; provided, however, that Special Interest and Additional Interest will accrue on the Notes to the extent, and only to the extent, provided in Sections 7.03 and 3.04, respectively. The amount of any such Special Interest or Additional Interest that is payable on any applicable Interest Payment Date will be the amount of unpaid Special Interest or Additional Interest, as applicable, that has accrued from, and including, the last date as of which such interest has been paid or duly provided for (or if later, the date as of which such interest has begun to accrue, as provided in Section 7.03 or 3.04, as applicable) to, but excluding, such Interest Payment Date (or, if earlier, the date as of which such interest has ceased to accrue, as provided in Section 7.03 or 3.04, as applicable). Subject to Section 2.05(D), if any Special Interest or Additional Interest has accrued on any Note, then such interest will be payable in arrears on the next Interest Payment Date to the Holder of such Note as of the Close of Business on the immediately preceding Interest Record Date. Special Interest and Additional Interest, if any, on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

- 16 -

(B)          DefaultedAmounts. If the Company fails to pay any cash 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 for each day, if any, during the period from, and including, such due date to, but excluding, the date of payment of such Defaulted Amount and Default Interest, which Default Interest will accrue on each such day at the combined rate at which Special Interest and Additional Interest accrues on such Note on such day (it being understood, for the avoidance of doubt, that no Default Interest will accrue on such Note on any day on which no Special Interest or Additional Interest accrues on such Note); and (iii) such Defaulted Amount and Default Interest will be paid, at the Company’s election, as provided in clause (i) or (ii) below.

(i)            Paymentof Default Amounts on a Special Payment Date. The Company will have the right to pay such Defaulted Amount and Default Interest 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 (1) such special record date is no more than fifteen (15), nor less than ten (10), calendar days before such payment date; and (2) at least fifteen (15) calendar days before such special record date, the Company sends 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.

(ii)           Paymentof Default Amount in Any Other Lawful Manner. If not paid in accordance with Section 2.05(B)(i), such Defaulted Amount and Default Interest will be paid by the Company in any other lawful manner.

Notwithstanding anything to the contrary in this Section 2.05(B), a Default in the payment or delivery of any Conversion Consideration when due will be cured upon the payment or delivery of the same (together, if applicable in the case of any cash Conversion Consideration, with Default Interest thereon) to the Person to whom such Conversion Consideration is payable or deliverable (determined in accordance with Article 5). The Trustee will have no duty to determine if Default Interest is payable or the amount thereof.

(C)          Delayof 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, for the avoidance of doubt, 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.”

- 17 -

(D)          SpecialProvision for Global Notes. If the first date on which any Special Interest or Additional Interest begins to accrue on a Global Note is on or after the fifth (5th) Business Day before an Interest Record Date and before the next Interest Payment Date, then, notwithstanding anything to the contrary in this Indenture or the Notes, the amount thereof accruing in respect of the period from, and including, such first date to, but excluding, such Interest Payment Date will not be payable on such Interest Payment Date but will instead be deemed to accrue (without duplication) entirely on such Interest Payment Date (and, for the avoidance of doubt, no interest will accrue as a result of the related delay).

**Section 2.06.**Registrar,Paying Agent and Conversion Agent.

(A)          Generally. The Company will maintain (i) an office or agency in the continental United States where Notes may be presented for registration of transfer or for exchange (the “Registrar”); (ii) an office or agency in the continental United States where Notes may be presented for payment (the “Paying Agent”); and (iii) an office or agency in the continental 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 and will receive compensation therefor in accordance with this Indenture and any other agreement between the Trustee and the Company. For the avoidance of doubt, the Company or any of its Subsidiaries may act as Registrar, Paying Agent or Conversion Agent.

(B)          Dutiesof 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 2.06(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)          InitialAppointments. The Company appoints the Trustee as, and designates its corporate trust office identified in Section 11.01 (as the same exists on the Issue Date) in the continental United States as the office for, the initial Paying Agent, the initial Registrar and the initial Conversion Agent.

**Section 2.07.**PayingAgent and Conversion Agent to Hold Property in Trust.

The Company will require each Paying Agent or Conversion Agent that is not the Trustee to agree in writing that such Note Agent will (A) hold in trust for the benefit of Holders or the Trustee all money and other property held by such Note Agent for payment or delivery due on the Notes; and (B) notify the Trustee of any default by the Company in making any such payment or delivery. The Company, at any time, may, and the Trustee, while any Default continues, may, require a Paying Agent or Conversion Agent to pay or deliver, as applicable, all money and other property held by it to the Trustee, after which payment or delivery, as applicable, such Note Agent (if not the Company or any of its Subsidiaries) will have no further liability for such money or property. If the Company or any of its Subsidiaries acts as Paying Agent or Conversion Agent, then (A) it will segregate and hold in a separate trust fund for the benefit of the Holders or the Trustee all money and other property held by it as Paying Agent or Conversion Agent; and (B) references in this Indenture or the Notes to the Paying Agent or Conversion Agent holding cash or other property, or to the delivery of cash or other property to the Paying Agent or Conversion Agent, in each case for payment or delivery to any Holders or the Trustee or with respect to the Notes, will be deemed to refer to cash or other property so segregated and held separately, or to the segregation and separate holding of such cash or other property, respectively. Upon the occurrence of any event pursuant to clause (viii) or (ix) of Section 7.01(A) with respect to the Company (or with respect to any Subsidiary of the Company acting as Paying Agent or Conversion Agent), the Trustee will serve as the Paying Agent or Conversion Agent, as applicable, for the Notes.

**Section 2.08.**HolderLists.

If the Trustee is not the Registrar, the Company will furnish to the Trustee, no later than seven (7) Business Days before each Interest Payment Date in respect of which any Special Interest or Additional Interest is payable, and at such other times as the Trustee may request, a list, in such form and as of such date or time as the Trustee may reasonably require, of the names and addresses of the Holders.

**Section 2.09.**Legends.

(F)          RestrictedStock Legend.

(i)            Each Conversion Share will bear the Restricted Stock Legend if the Note upon the Conversion of which such Conversion Share was issued was (or would have been had it not been Converted) a Transfer-Restricted Security at the time such Conversion Share was issued; provided, however, that such Conversion Share need not bear the Restricted Stock Legend if the Company determines, in its reasonable discretion, that such Conversion Share need not bear the Restricted Stock Legend.

(ii)           Notwithstanding anything to the contrary in this Section 2.09(F), a Conversion Share need not bear a Restricted Stock Legend if such Conversion Share is issued in an uncertificated form that does not permit affixing legends thereto, provided the Company takes measures (including the assignment thereto of a “restricted” CUSIP number) that it reasonably deems appropriate to enforce the transfer restrictions referred to in the Restricted Stock Legend.

**Section 2.10.**Transfersand Exchanges; Certain Transfer Restrictions.

(A)          ProvisionsApplicable to All Transfers and Exchanges.

(i)            Generally. Subject to this Section 2.10, 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)           Transferredand Exchanged Notes Remain Valid Obligations of the Company. 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 2.10(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)          NoServices Charge; Transfer Taxes. 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 documentary, stamp or similar issue or transfer tax or duty or similar governmental charge that may be imposed in connection with any transfer, exchange or Conversion of Notes, other than exchanges pursuant to Section 2.11, 2.17 or 8.05 not involving any transfer.

(iv)          Transfersand Exchanges Must Be in Authorized Denominations. 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)          Trustee’sDisclaimer. The Trustee will have no obligation or duty to monitor, determine or inquire as to compliance with any transfer restrictions imposed under this Indenture or applicable law with respect to any Security, other than to require the delivery of such certificates or other documentation or evidence as expressly required by this Indenture and to examine the same to determine substantial compliance as to form with the requirements of this Indenture.

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;

(ii)           remove such Restricted Note Legend; or

(iii)          register the transfer of such Note to the name of another Person,

then the Company, the Trustee and the Registrar may refuse to effect such identification, removal or transfer, as applicable, unless there is delivered to the Company, the Trustee and the Registrar such certificates or other documentation or evidence as the Company, the Trustee and the Registrar may reasonably require for the Company to determine that such identification, removal or transfer, as applicable, complies with the Securities Act and other applicable securities laws; provided, however, that no such certificates, documentation or evidence need be so delivered on or after the Free Trade Date with respect to such Note unless the Company determines, in its reasonable discretion, that such Note is not eligible to be offered, sold or otherwise transferred pursuant to Rule 144 or otherwise without any requirements as to volume, manner of sale, availability of current public information or notice under the Securities Act.

If a Global Note (or any portion thereof) is to be Converted pursuant to Article 5 or repurchased pursuant to a Repurchase Upon Fundamental Change or Redemption, then, promptly after the time such Note (or such portion) is deemed to cease to be outstanding pursuant to Section 2.18, 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 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).

If such Note bears a “restricted” CUSIP or ISIN number at the time of such delivery, then, upon such delivery, such Note will be deemed, pursuant to this Section 2.12 and the footnotes to the CUSIP and ISIN numbers set forth on the face of the certificate representing such Note, to thereafter bear the “unrestricted” CUSIP and ISIN numbers identified in such footnotes; provided, however, that if such Note is a Global Note and the Depositary thereof requires a mandatory exchange or other procedure to cause such Global Note to be identified by “unrestricted” CUSIP and ISIN numbers in the facilities of such Depositary, then, (x) the Company will effect such exchange or procedure as soon as reasonably practicable; and (y) for purposes of Section 3.04 and the definition of Freely Tradable, such Global Note will not be deemed to be identified by “unrestricted” CUSIP and ISIN numbers until such time as such exchange or procedure is effected.

**Section 2.13.**ReplacementNotes.

If a Holder of any Note claims that such Note has been mutilated, lost, destroyed or wrongfully taken, then the Company will issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a replacement Note upon surrender to the Trustee of such mutilated Note, or upon delivery to the Trustee of evidence of such loss, destruction or wrongful taking reasonably satisfactory to the Trustee and the Company.

**Section 2.17.**TemporaryNotes.

Until definitive Notes are ready for delivery, the Company may issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, temporary Notes. Temporary Notes will be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. The Company will promptly prepare, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, definitive Notes in exchange for temporary Notes.

**Article 3.**Covenants

**Section 3.01.**Paymenton Notes.

Before 11:00 A.M., New York City time, on each Redemption Date, each Fundamental Change Repurchase Date and on each Interest Payment Date in respect of which any Special Interest or Additional Interest is payable, and on the Maturity Date and each other date on which any cash amount is due on the Notes, the Company will deposit, or will cause there to be deposited, with the Paying Agent cash, in funds immediately available on such date, sufficient to pay the cash amount due on the applicable Notes on such date. The Paying Agent will return to the Company, as soon as practicable, any money not required for such purpose.

**Section 3.02.**ExchangeAct Reports.

(A)          Generally. The Company will send to the Trustee copies of all reports that the Company is required to file with the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act (other than Form 8-K reports) within fifteen (15) calendar days after the date that the Company is required to file the same (after giving effect to all applicable grace periods under the Exchange Act); provided, however, that the Company need not send to the Trustee any material for which the Company has received, or is seeking in good faith and has not been denied, confidential treatment by the SEC. Any report that the Company files with the SEC through the EDGAR system (or any successor thereto) will be deemed to be sent to the Trustee at the time such report is so filed via the EDGAR system (or such successor). Upon the request of any Holder, the Trustee will provide to such Holder a copy of any report that the Company has sent the Trustee pursuant to this Section 3.02(A), other than a report that is deemed to be sent to the Trustee pursuant to the preceding sentence.

The “grace periods” referred to in the preceding paragraph with respect to any report will include the maximum period afforded by Rule 12b-25 (or any successor rule thereto) under the Exchange Act regardless of whether the Company files, or indicates in the related Form 12b-25 (or any successor form thereto) that the Company expects to or will file, such report before the expiration of such maximum period. For the avoidance of doubt, if the Company fails to file with the SEC any report pursuant to Section 13(a) or 15(d) of the Exchange Act (other than Form 8-K reports) on or before the date that the Company is required to file the same (after giving effect to all applicable grace periods under the Exchange Act), then such failure will not constitute a Default with respect to the covenant set forth in this Section 3.02(A) at any time before the lapsing of the fifteen (15) calendar days referred to in the first sentence of this Section 3.02(A).

- 29 -

(B)          Trustee’sDisclaimer. The Trustee need not determine whether the Company has filed any material via the EDGAR system (or such successor). The sending or filing of reports pursuant to Section 3.02(A) will not be deemed to constitute actual or constructive notice to the Trustee of any information contained, or determinable from information contained, therein, including the Company’s compliance with any of its covenants under this Indenture.

**Section 3.03.**Rule 144AInformation.

If the Company is not subject to Section 13 or 15(d) of the Exchange Act at any time when any Notes or shares of Common Stock issuable upon Conversion of the Notes are outstanding and constitute “restricted securities” (as defined in Rule 144), then the Company (or its successor) will promptly provide, to the Trustee and, upon written request, to any Holder, beneficial owner or prospective purchaser of such Notes or shares, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares pursuant to Rule 144A; provided, however, that, from and after the De-Legending Deadline Date of any Note, such information need not be provided with respect to such Note, or any share of Common Stock issued upon Conversion of such Note, if such Note or share, as applicable, is Freely Tradable (determined, with respect to any share of Common Stock, as each reference to any Note in the definition of “Freely Tradable” were instead a reference to shares of Common Stock).

**Section 3.04.**AdditionalInterest.

(A)          Accrualof Additional Interest.

(i)            If, at any time during the six (6) month period beginning on, and including, the date that is six (6) months after the Last Original Issue Date of any Note,

(1)          the Company fails to timely file any report (other than Form 8-K reports) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (after giving effect to all applicable grace periods thereunder); or

(2)          such Note is not otherwise Freely Tradable,

then Additional Interest will accrue on such Note for each day during such period on which such failure is continuing or such Note is not Freely Tradable. The “grace periods” referred to in the preceding sentence with respect to any report will include the maximum period afforded by Rule 12b-25 (or any successor rule thereto) under the Exchange Act regardless of whether the Company files, or indicates in the related Form 12b-25 (or any successor form thereto) that the Company expects to or will file, such report before the expiration of such maximum period.

- 30 -

(ii)           In addition, Additional Interest will accrue on a Note on each day on which such Note is not Freely Tradable on or after the De-Legending Deadline Date for such Note.

(B)          Amountand Payment of Additional Interest. Subject to Section 3.04(C), any Additional Interest that accrues on a Note pursuant to Section 3.04(A) will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first ninety (90) days on which Additional Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof; provided, however, that in no event will Additional Interest, together with any Special Interest, accrue on any day on a Note at a combined rate per annum that exceeds one half of one percent (0.50%). For the avoidance of doubt, any Additional Interest that accrues on a Note will, subject to the proviso of the immediately preceding sentence, be in addition to any Special Interest that accrues on such Note.

(i)            Generally. Notwithstanding anything to the contrary in this Section 3.04, but subject to Section 3.04(C)(iii), Additional Interest that accrues on any Note for any period on or after the De-Legending Deadline Date of such Note will not be payable on any Interest Payment Date occurring on or after such De-Legending Deadline Date unless (1) a Holder (or an owner of a beneficial interest in a Global Note) has delivered to the Company and the Trustee, no later than the fifth (5th) Business Day before the Interest Record Date immediately before such Interest Payment Date, a written notice (a “Deferred Additional Interest Demand Request”) demanding payment of Additional Interest; or (2) the Company, in its sole and absolute discretion, elects, by sending notice of such election (a “Notice of Election to Pay Deferred Additional Interest”) to Holders and the Trustee, before such Interest Record Date, to pay such Additional Interest on such Interest Payment Date (any accrued and unpaid Additional Interest that, in accordance with this sentence, is not paid on such Interest Payment Date, “Deferred Additional Interest”). Once any accrued and unpaid Additional Interest becomes payable on an Interest Payment Date (whether as a result of the delivery of a written notice pursuant to clause(1) above or, if earlier, the Company’s election to pay the same pursuant to clause (2) above), Additional Interest will thereafter not be subject to deferral pursuant to this Section 3.04(C).

(ii)           InterpretiveProvisions. Each reference in this Indenture or the Notes to any accrued interest (including in the definitions of the Redemption Price and the Fundamental Change Repurchase Price for any Note) or to any accrued Additional Interest includes, to the extent applicable, and without duplication, any Deferred Additional Interest. For the avoidance of doubt, the failure to pay any accrued and unpaid Additional Interest on an Interest Payment Date will not constitute a Default or an Event of Default under this Indenture or the Notes if such payment is deferred in accordance with Section 3.04(C)(i). Otherwise, such a failure to pay will be subject to Section 7.01(A)(ii).

(iii)          Paymentor Extinguishment Upon Maturity. Notwithstanding anything to the contrary in this Indenture or the Notes, if (1) any unpaid Deferred Additional Interest exists on any Notes as of the Close of Business on the Interest Record Date immediately preceding the Maturity Date; (2) no Holder (or owner of a beneficial interest in a Global Note) has delivered a Deferred Additional Interest Demand Request in the manner set forth in Section 3.04(C)(i) on or before the fifth (5th) Business Day before such Interest Record Date; and (3) the Company has not sent a Notice of Election to Pay Deferred Additional Interest in the manner set forth in Section 3.04(C)(i) before such Interest Record Date, then Deferred Additional Interest on each Note then outstanding will cease to accrue, and all Deferred Additional Interest on such Note will be deemed to be extinguished on the following date: (a) if such Note is to be Converted, the Conversion Date for such Conversion (it being understood, for the avoidance of doubt, that the Conversion Consideration therefor need not include the payment of any such Deferred Additional Interest); and (b) in all other cases, the later of (x) the Maturity Date; and (y) the first date on which the Company has repaid the principal of, and accrued and unpaid interest (other than such Deferred Additional Interest) on, such Note in full.

- 31 -

(D)          Noticeof Accrual of Additional Interest; Trustee’s Disclaimer. The Company will send notice to the Holder of each Note, and to the Trustee, of the commencement and termination of any period in which Additional Interest accrues on such Note, except that no such notice is required in respect of any Additional Interest that is deferred in accordance with Section 3.04(C). In addition, if Additional Interest accrues on any Note, then, no later than five (5) Business Days before each date on which such Additional Interest is to be paid, the Company will deliver an Officer’s Certificate to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay Additional Interest on such Note on such date of payment; and (ii) the amount of such Additional Interest that is payable on such date of payment. The Trustee (x) will have no duty to determine whether any Additional Interest is payable (or whether the same is deferred or is accruing interest) or the amount thereof; and (y) may assume (without inquiry) that no Additional Interest is payable or has been deferred unless and until the Company delivers such Officer’s Certificate.

(E)          ExclusiveRemedy. The accrual of Additional Interest will be the exclusive remedy available to Holders for the failure of their Notes to become Freely Tradable.

**Section 3.05.**Complianceand Default Certificates.

(A)          AnnualCompliance Certificate. Within ninety (90) days after the last day of each fiscal year of the Company, beginning with the first such fiscal year ending after the date of this Indenture, the Company will deliver an Officer’s Certificate to the Trustee stating (i) that the signatory thereto has supervised a review of the activities of the Company and its Subsidiaries during such fiscal year with a view towards determining whether any Default has occurred; and (ii) whether, to such signatory’s knowledge, a Default has occurred or is continuing (and, if so, describing all such Defaults and what action the Company is taking or proposes to take with respect thereto).

(B)          DefaultCertificate. If a Default occurs, then the Company will, within thirty (30) days after its first occurrence, deliver an Officer’s Certificate to the Trustee describing the same and what action the Company is taking or proposes to take with respect thereto; provided, however, that the Company will not be required to deliver such Officer’s Certificate at any time after such Default is cured or waived.

- 32 -

**Section 3.06.**Stay,Extension and Usury Laws.

To the extent that it may lawfully do so, the Company (A) agrees that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law (wherever or whenever enacted or in force) that may affect the covenants or the performance of this Indenture; and (B) expressly waives all benefits or advantages of any such law and agrees that it will not, by resort to any such law, hinder, delay or impede the execution of any power granted to the Trustee by this Indenture, but will suffer and permit the execution of every such power as though no such law has been enacted.

**Section 3.07.**Acquisitionof Notes by the Company and its Affiliates.

Without limiting the generality of Section 2.18, Notes that the Company or any of its Subsidiaries may repurchase will be considered outstanding for all purposes under this Indenture (except to the extent provided in Section 2.16) unless and until such time the Company surrenders the Notes to the Trustee for cancellation and, upon receipt of a written order from the Company, the Trustee will cancel all notes so surrendered. The Company will use commercially reasonable efforts to prevent any of its controlled Affiliates from acquiring any Note (or any beneficial interest therein).

**Article 4.**Repurchaseand Redemption

(B)          RepurchaseProhibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or before the Fundamental Change Repurchase Date for a Repurchase Upon Fundamental Change (including a rescission as a result of the payment of the related Fundamental Change Repurchase Price, and any related interest pursuant to the proviso to the first sentence of Section 4.02(D), on such Fundamental Change Repurchase Date), then (i) the Company may not repurchase any Notes pursuant to this Section 4.02; and (ii) the Company will cause any Notes theretofore surrendered for such Repurchase Upon Fundamental Change to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interest in such Notes in accordance with the Depositary Procedures).

The Fundamental Change Repurchase Date for any Fundamental Change will be a Business Day of the Company’s choosing that is no more than thirty five (35), nor less than twenty (20), Business Days after the date the Company sends the related Fundamental Change Notice pursuant to Section 4.02(E).

(D)          FundamentalChange Repurchase Price.

(i)            Deliveryof Fundamental Change Repurchase Notice and Notes to Be Repurchased. To exercise its Fundamental Change Repurchase Right for a Note following a Fundamental Change, a Holder must deliver to the Paying Agent:

(1)          before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date (or such later time as may be required by law), a duly completed, written Fundamental Change Repurchase Notice with respect to such Note; and

(2)          such Note, duly endorsed for transfer (if such Note is a Physical Note) or by book-entry transfer (if such Note is a Global Note).

The Paying Agent will promptly deliver to the Company a copy of each Fundamental Change Repurchase Notice that it receives.

(3)          that such Holder is exercising its Fundamental Change Repurchase Right with respect to such principal amount of such Note;

provided, however, that if such Note is a Global Note, then such Fundamental Change Repurchase Notice must comply with the Depositary Procedures (and any such Fundamental Change Repurchase Notice delivered in compliance with the Depositary Procedures will be deemed to satisfy the requirements of this Section 4.02(F)).

(iii)          Withdrawalof Fundamental Change Repurchase Notice. A Holder that has delivered a Fundamental Change Repurchase Notice with respect to a Note may withdraw such Fundamental Change Repurchase Notice by delivering a written notice of withdrawal to the Paying Agent at any time before the Close of Business on the Business Day immediately before the related Fundamental Change Repurchase Date. Such withdrawal notice must state:

For the avoidance of doubt, the calling of any Notes for Redemption will constitute a Make-Whole Fundamental Change with respect to such Notes pursuant to clause (B) of the definition thereof.

(C)          RedemptionProhibited in Certain Circumstances. If the principal amount of the Notes has been accelerated and such acceleration has not been rescinded on or before the Redemption Date (including a rescission as a result of the payment of the related Redemption Price, and any related interest pursuant to the proviso to the first sentence of Section 4.03(E), on such Redemption Date), then (i) the Company may not call for Redemption or otherwise redeem any Notes pursuant to this Section 4.03; and (ii) the Company will cause any Notes theretofore surrendered for such Redemption to be returned to the Holders thereof (or, if applicable with respect to Global Notes, cancel any instructions for book-entry transfer to the Company, the Trustee or the Paying Agent of the applicable beneficial interests in such Notes in accordance with the Depositary Procedures).

The Redemption Price for any Note called for Redemption is an amount in cash equal to the principal amount of such Note plus accrued and unpaid Special Interest and Additional Interest, if any, on such Note to, but excluding, the Redemption Date for such Redemption; provided, however, that if any payment of Special Interest or Additional Interest is due in respect of any Interest Payment Date and such Redemption Date is after the related Interest Record Date and on or before such Interest Payment Date, then (i) the Holder of such Note at the Close of Business on such Interest Record Date will be entitled, notwithstanding such Redemption, to receive, on or, at the Company’s election, before such Interest Payment Date, such payment of Special Interest or Additional Interest, as applicable (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date, if such Redemption Date is before such Interest Payment Date); and (ii) the Redemption Price will not include accrued and unpaid Special Interest or Additional Interest on such Note to, but excluding, such Redemption Date. For the avoidance of doubt, if such Interest Payment Date is not a Business Day within the meaning of Section 2.05(C) and such Redemption Date occurs on the Business Day immediately after such Interest Payment Date, then (x) accrued and unpaid Special Interest or Additional Interest, as applicable, to, but excluding, such Interest Payment Date will be paid, in accordance with Section 2.05(C), on the next Business Day to Holders as of the Close of Business on the immediately preceding Interest Record Date; and (y) the Redemption Price will include Special Interest and Additional Interest, if any, on Notes to be redeemed from, and including, such Interest Payment Date.

(G)          Selectionand Conversion of Notes to Be Redeemed in Part.

(i)            If less than all Notes then outstanding are called for Redemption, then the Notes to be redeemed will be selected by the Company as follows: (1) in the case of Global Notes, in accordance with the Depositary Procedures; and (2) in the case of Physical Notes, pro rata, by lot or by such other method the Company considers fair and appropriate.

(ii)           If only a portion of a Note is subject to Redemption and such Note is Converted in part, then the Converted portion of such Note will be deemed to be from the portion of such Note that was subject to Redemption.

- 40 -

(J)            Repurchasesor Other Acquisitions Other Than by Redemption Not Affected. For the avoidance of doubt, nothing in this Section 4.03 will limit or otherwise apply to any repurchase or other acquisition, by the Company or its Affiliates, or any other Person, of any Notes not by Redemption (including in open market transactions, private or public tender or exchange offers or otherwise).

**Article 5.**TheConversion of Notes

**Section 5.01.**Rightto Convert.

(A)          Generally. Subject to the provisions of this Article 5, each Holder may, at its option, Convert such Holder’s Notes into Conversion Consideration.

(B)          Conversionsin Part. Subject to the terms of this Indenture, Notes may be Converted in part, but only in Authorized Denominations. Provisions of this Article 5 applying to the Conversion of a Note in whole will equally apply to Conversions of a permitted portion of a Note.

(i)            Generally. Subject to Section 5.01(C)(ii), a Note may be Converted only in the following circumstances:

(1)          ConversionUpon Satisfaction of Common Stock Sale Price Condition. Prior to August 15, 2031, a Holder may Convert its Notes during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending on June 30, 2026, if the Last Reported Sale Price per share of Common Stock exceeds one hundred and thirty percent (130%) of the Conversion Price for each of at least twenty (20) Trading Days (whether or not consecutive) during the thirty (30) consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter.

(2)          ConversionUpon Satisfaction of Note Trading Price Condition. Prior to August 15, 2031, a Holder may Convert its Notes during the five (5) consecutive Business Days immediately after any ten (10) consecutive Trading Day period (such ten (10) consecutive Trading Day period, the “Measurement Period”) if 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 below, for each Trading Day of the Measurement Period was less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. The condition set forth in the preceding sentence is referred to in this Indenture as the “Trading Price Condition.”

- 41 -

The Trading Price will be determined by the Bid Solicitation Agent pursuant to this Section 5.01(C)(i)(2) and the definition of “Trading Price.” The Bid Solicitation Agent (if not the Company) will have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination in writing, and the Company will have no obligation to make such request (or seek bids itself) unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock and the Conversion Rate. If a Holder provides such evidence, then the Company will (if acting as Bid Solicitation Agent), or will instruct the Bid Solicitation Agent to, determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day. If the Trading Price Condition has been met as set forth above, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same. If, on any Trading Day after the Trading Price Condition has been met as set forth above, the Trading Price per $1,000 principal amount of Notes is greater than or equal to ninety eight percent (98%) of the product of the Last Reported Sale Price per share of Common Stock on such Trading Day and the Conversion Rate on such Trading Day, then the Company will notify the Holders, the Trustee and the Conversion Agent of the same.

(a)          CertainDistributions. If, before August 15, 2031, the Company elects to:

(I)          distribute, to all or substantially all holders of Common Stock, any rights, options or warrants (other than rights issued pursuant to a stockholder rights plan, so long as such rights have not separated from the Common Stock and are not exercisable until the occurrence of a triggering event, except that such rights will be deemed to be distributed under this clause (I) upon their separation from the Common Stock or upon the occurrence of such triggering event) entitling them, for a period of not more than sixty (60) 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 (determined in the manner set forth in the third paragraph of Section 5.05(A)(ii)); or

- 42 -

then, in either case, (x) the Company will send notice of such distribution, and of the related right to Convert Notes, to Holders, the Trustee and the Conversion Agent at least fifty (50) Scheduled Trading Days before the Ex-Dividend Date for such distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder rights plan or the occurrence of any such triggering event under a stockholder rights plan, as soon as reasonably practicable after the Company becomes aware that such separation or triggering event has occurred or will occur); and (y) once the Company has sent such notice, Holders may Convert their Notes at any time until the earlier of the Close of Business on the Business Day immediately before such Ex-Dividend Date and the Company’s announcement that such distribution will not take place; provided, however, that the Notes will not become Convertible pursuant to clause (y) above (but the Company will be required to send notice of such distribution pursuant to clause (x) above) on account of such distribution 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, in such distribution 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 record date for such distribution; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such record date; provided, further, that if the Company is then otherwise permitted to settle Conversions of Notes by Physical Settlement (and, for the avoidance of doubt, the Company has not elected another Settlement Method to apply, including pursuant to Section 5.03(A)(i)(1)), then the Company may instead elect to provide such notice at least ten (10) Scheduled Trading Days before such Ex-Dividend Date, in which case (x) the Company must settle all Conversions of Notes with a Conversion Date occurring on or after the date the Company provides such notice and on or before the Business Day immediately before the Ex-Dividend Date for such distribution (or any earlier announcement by the Company that such distribution will not take place) by Physical Settlement; and (y) such notice must state that all such Conversions will be settled by Physical Settlement.

If, prior to August 15, 2031, a Fundamental Change, Make-Whole Fundamental Change (other than a Make-Whole Fundamental Change pursuant to clause (B) of the definition thereof) or Common Stock Change Event occurs (other than a merger or other business combination transaction that is effected solely to change the Company’s jurisdiction of incorporation and that does not constitute a Fundamental Change or a Make-Whole Fundamental Change), then, in each case, Holders may Convert their Notes at any time from, and including, the effective date of such transaction or event to, and including, the thirty fifth (35th) Trading Day after such effective date (or, if such transaction or event also constitutes a Fundamental Change (other than an Exempted Fundamental Change), to, but excluding, the related Fundamental Change Repurchase Date); provided, however, that if the Company does not provide the notice referred to in the immediately following sentence by such effective date, then the last day on which the Notes are Convertible pursuant to this sentence will be extended by the number of Business Days from, and including, such effective date to, but excluding, the date the Company provides such notice. No later than the second (2nd) Business Day after such effective date, the Company will send notice to the Holders, the Trustee and the Conversion Agent of such transaction or event, such effective date and the related right to Convert Notes.

- 43 -

(4)          ConversionUpon Redemption. If the Company calls any Note for Redemption, then the Holder of such Note may Convert such Note at any time before the Close of Business on the second (2nd) Business Day immediately before the related Redemption Date (or, if the Company fails to pay the Redemption Price due on such Redemption Date in full, at any time until such time as the Company pays such Redemption Price in full).

For the avoidance of doubt, the Notes may become Convertible pursuant to any one or more of the preceding sub-paragraphs of this Section 5.01(C)(i) and the Notes ceasing to be Convertible pursuant to a particular sub-paragraph of this Section 5.01(C)(i) will not preclude the Notes from being Convertible pursuant to any other sub-paragraph of this Section 5.01(C)(i).

(ii)           Limitationsand Closed Periods. Notwithstanding anything to the contrary in this Indenture or the Notes:

(1)          Notes may be surrendered for Conversion only after the Open of Business and before the Close of Business on a day that is a Business Day;

(2)          in no event may any Note be Converted after the Close of Business on the second (2nd) Scheduled Trading Day immediately before the Maturity Date;

- 44 -

(3)          if the Company calls any Note for Redemption pursuant to Section 4.03, then the Holder of such Note may not Convert such Note after the Close of Business on the second (2nd) Business Day immediately before the applicable Redemption Date, except to the extent the Company fails to pay the Redemption Price for such Note in accordance with this Indenture; and

(4)          if a Fundamental Change Repurchase Notice is validly delivered pursuant to Section 4.02(F) with respect to any Note, then such Note may not be Converted, except to the extent (a) such Note is not subject to such notice; (b) such notice is withdrawn in accordance with Section 4.02(F); or (c) the Company fails to pay the Fundamental Change Repurchase Price for such Note in accordance with this Indenture.

For the avoidance of doubt, if the Conversion Date of a Note to be converted is on an Interest Payment Date in respect of which any Special Interest or Additional Interest is payable, then the Holder of such Note at the Close of Business on the Interest Record Date immediately before such Interest Payment Date will be entitled to receive, on such Interest Payment Date, such Special Interest or Additional Interest, as applicable.

- 45 -

(E)          Taxesand 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 or delivery of any shares of Common Stock upon such Conversion, except any tax or duty that is due because the Converting Holder requests those shares to be registered in a name other than the Holder’s name.

(F)          ConversionAgent 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.**SettlementUpon Conversion.

(A)          SettlementMethod. Upon the Conversion of any Note, the Company will settle such Conversion by paying or delivering, as applicable and as provided in this Article 5, either (x) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(1) (a “Physical Settlement”); (y) solely cash as provided in Section 5.03(B)(i)(2) (a “Cash Settlement”); or (z) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 5.03(B)(i)(3) (a “CombinationSettlement”).

(i)            TheCompany’s Right to Elect Settlement Method. The Company will have the right to elect the Settlement Method applicable to any Conversion of a Note; provided, however, that:

(1)          subject to clause (3) below, all Conversions of Notes with a Conversion Date that occurs on or after August 15, 2031 will be settled using the same Settlement Method, and the Company will send notice of such Settlement Method to Holders no later than the Open of Business on August 15, 2031;

(2)          subject to clause (3) below, if the Company elects a Settlement Method with respect to the Conversion of any Note whose Conversion Date occurs before August 15, 2031, then the Company will send notice of such Settlement Method to the Holder of such Note no later than the Close of Business on the Business Day immediately after such Conversion Date;

(3)          if any Notes are called for Redemption, then (a) the Company will specify, in the related Redemption Notice (and, in the case of a Redemption of less than all outstanding Notes, in a notice simultaneously sent to all Holders of Notes not called for Redemption) sent pursuant to Section 4.03(F), the Settlement Method that will apply to all Conversions of Notes with a Conversion Date that occurs on or after the related Redemption Notice Date and on or before the second (2nd) Business Day before the related Redemption Date; and (b) if such Redemption Date occurs on or after August 15, 2031, then such Settlement Method must be the same Settlement Method that, pursuant to clause (1) above, applies to all Conversions of Notes with a Conversion Date that occurs on or after August 15, 2031;

- 46 -

(4)          the Company will use the same Settlement Method for all Conversions of Notes with the same Conversion Date (and, for the avoidance of doubt, the Company will not be obligated to use the same Settlement Method with respect to Conversions of Notes with different Conversion Dates, except as provided in clause (1) or (3) above);

(5)          if the Company does not timely elect a Settlement Method with respect to the Conversion of a Note, then the Company will be deemed to have elected the Default Settlement Method (and, for the avoidance of doubt, the failure to timely make such election will not constitute a Default or Event of Default);

(6)          if the Company timely elects Combination Settlement with respect to the Conversion of a Note but does not timely notify the Holder of such Note of the applicable Specified Dollar Amount, then the Specified Dollar Amount for such Conversion will be deemed to be $1,000 per $1,000 principal amount of Notes (and, for the avoidance of doubt, the failure to timely send such notification will not constitute a Default or Event of Default); and

(7)          the Settlement Method will be subject to Sections 4.03(D) and 5.01(C)(i)(3)(a).

At or before the time the Company sends any notice referred to in the preceding sentence, the Company will send a copy of such notice to the Trustee and the Conversion Agent, but the failure to timely send such copy will not affect the validity of any Settlement Method election.

(ii)           TheCompany’s Right to Irrevocably Fix Settlement Method. The Company will have the right, exercisable at its election by sending notice of such exercise to the Holders (with a copy to the Trustee and the Conversion Agent), to irrevocably fix the Settlement Method, to any Settlement Method that the Company is then permitted to elect, that will apply to all Conversions of Notes with a Conversion Date that occurs on or after the date such notice is sent to Holders. For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend this Indenture or the Notes, including pursuant to Section 8.01(G) (it being understood, however, that the Company may nonetheless choose to execute such an amendment at its option).

- 47 -

(B)          ConversionConsideration.

(i)            Generally. The type and amount of consideration (the “Conversion Consideration”) due in respect of each $1,000 principal amount of a Note to be Converted will be as follows:

(1)          if Physical Settlement applies to such Conversion, a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such Conversion;

(2)          if Cash Settlement applies to such Conversion, cash in an amount equal to the sum of the Daily Conversion Values for each VWAP Trading Day in the Observation Period for such Conversion; or

(3)          if Combination Settlement applies to such Conversion, consideration consisting of (a) a number of shares of Common Stock equal to the sum of the Daily Share Amounts for each VWAP Trading Day in the Observation Period for such Conversion; and (b) an amount of cash equal to the sum of the Daily Cash Amounts for each VWAP Trading Day in such Observation Period.

(ii)           Cashin Lieu of Fractional Shares. If Physical Settlement or Combination Settlement applies to the Conversion of any Note and the number of shares of Common Stock deliverable pursuant to Section 5.03(B)(i) upon such Conversion 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) (x) the Daily VWAP on the Conversion Date for such Conversion (or, if such Conversion Date is not a VWAP Trading Day, the immediately preceding VWAP Trading Day), in the case of Physical Settlement; or (y) the Daily VWAP on the last VWAP Trading Day of the Observation Period for such Conversion, in the case of Combination Settlement.

(iii)          Conversionof 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.

(iv)          Noticeof Calculation of Conversion Consideration. If Cash Settlement or Combination Settlement applies to the Conversion of any Note, then the Company will determine the Conversion Consideration due thereupon promptly following the last VWAP Trading Day of the applicable Observation Period and will promptly thereafter send notice to the Trustee and the Conversion Agent of the same and the calculation thereof in reasonable detail. Neither the Trustee nor the Conversion Agent will have any duty to make any such determination.

(C)          Deliveryof the Conversion Consideration. Except as set forth in Sections 5.05(D) and 5.09, the Company will pay or deliver, as applicable, the Conversion Consideration due upon the Conversion of any Note to the Holder as follows: (i) if Cash Settlement or Combination Settlement applies to such Conversion, on the second (2nd) Business Day immediately after the last VWAP Trading Day of the Observation Period for such Conversion; and (ii) if Physical Settlement applies to such Conversion, on the second (2nd) Business Day immediately after the Conversion Date for such Conversion; provided, however, that if Physical Settlement applies to the Conversion of any Note with a Conversion Date that is after the Interest Record Date immediately before the Maturity Date, then, solely for purposes of such Conversion, the Company will pay or deliver, as applicable, the Conversion Consideration due upon such Conversion on the Maturity Date (or, if the Maturity Date is not a Business Day, the next Business Day) and the Conversion Date will instead be deemed to be the second (2nd) Business Day immediately before the Maturity Date.

- 48 -

(D)          DeemedPayment of Principal and Interest; Settlement of Accrued Interest Notwithstanding Conversion. If a Holder Converts a Note, then the Company will not adjust the Conversion Rate to account for any accrued and unpaid Special Interest or Additional Interest on such Note, and, except as provided in Section 5.02(D), the Company’s delivery of the Conversion Consideration due in respect of such Conversion will be deemed to fully satisfy and discharge the Company’s obligation to pay the principal of, and accrued and unpaid interest, if any, on, such Note to, but excluding the Conversion Date. As a result, except as provided in Section 5.02(D), any accrued and unpaid interest on a Converted Note will be deemed to be paid in full rather than cancelled, extinguished or forfeited.

**Section 5.04.**Reserveand Status of Common Stock Issued Upon Conversion.

(A)          StockReserve. At all times when any Notes are outstanding, the Company will reserve (out of its authorized and not outstanding shares of Common Stock that are not reserved for other purposes) a number of shares of Common Stock sufficient to permit the Conversion of all then-outstanding Notes, assuming (x) Physical Settlement will apply to such Conversion; and (y) the Conversion Rate is increased by the maximum amount pursuant to which the Conversion Rate may be increased pursuant to Section 5.07. To the extent the Company delivers shares of Common Stock held in its treasury in settlement of the Conversion of any Notes, each reference in this Indenture or the Notes to the issuance of shares of Common Stock in connection therewith will be deemed to include such delivery, mutatis mutandis.

(B)          Statusof Conversion Shares; Listing. Each Conversion Share, if any, delivered upon Conversion of any Note will be a newly issued or treasury share (except that any Conversion Share delivered by a designated financial institution pursuant to Section 5.08 need not be a newly issued or treasury share) and will be duly authorized, 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 use commercially reasonable efforts to 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 5.05.**Adjustmentsto the Conversion Rate.

(A)          EventsRequiring an Adjustment to the Conversion Rate. The Conversion Rate will be adjusted from time to time as follows:

(i)            StockDividends, 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:

where:

CR0	=	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately<br>before the Open of Business on the effective date of such stock split or stock combination, as applicable;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date or effective date, as applicable;
OS0	=	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective date, as<br>applicable, without giving effect to such dividend, distribution, stock split or stock combination; and
OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock<br>combination.

If any dividend, distribution, stock split or stock combination of the type described in this Section 5.05(A)(i) is declared or announced, but not so paid or made, then the Conversion Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution, stock split or stock combination not been declared or announced.

- 49 -

(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 Sections 5.05(A)(iii)(1) and 5.05(F) will apply) entitling such holders, for a period of not more than sixty (60) 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:

where:

CR0	=	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
OS	=	the number of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date;
X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and
Y	=	a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to exercise such rights, options or warrants by<br>(y) the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Days ending on, and including,<br>the Trading Day immediately before the date such distribution is announced.

To the extent such rights, options or warrants are not so distributed, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of only the rights, options or warrants, if any, actually distributed. In addition, to the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate for such distribution been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, options or warrants.

For purposes of this Section 5.05(A)(ii) and Section 5.01(C)(i)(3)(a)(I), in determining whether any rights, options or warrants entitle holders of Common Stock 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 the distribution of such rights, options or warrants is announced, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration, if not cash, to be determined by the Company in good faith and in a commercially reasonable manner.

- 50 -

(iii)          Spin-Offsand Other Distributed Property.

(1)          DistributionsOther 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:

(u)          dividends, distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(i) or 5.05(A)(ii);

(v)          dividends or distributions paid exclusively in cash, for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iv);

(w)          rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 5.05(F);

(x)          Spin-Offs for which an adjustment to the Conversion Rate is required (or would be required without regard to Section 5.05(C)) pursuant to Section 5.05(A)(iii)(2);

(y)          a distribution solely pursuant to a tender offer or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply; and

(z)          a distribution solely pursuant to a Common Stock Change Event, as to which Section 5.09 will apply,

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

where:

CR0	=	the Conversion Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;
CR1	=	the Conversion Rate in effect immediately after the Open of Business on such Ex-Dividend Date;
SP	=	the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive<br> Trading Days ending on, and including, the Trading Day immediately before such Ex-Dividend Date; and
FMV	=	the fair market value (as determined by the Company in good faith and in a commercially reasonable manner), as of such Ex-Dividend Date,<br>of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed per share of Common<br>Stock pursuant to such distribution;

- 51 -

provided, however, that if FMV is equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such distribution, at the same time and on the same terms as holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants that such Holder would have received in such distribution if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

To the extent such distribution is not so paid or made, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid.

(2)          Spin-Offs. If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity interests, 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 (x) a Common Stock Change Event, as to which Section 5.09 will apply; or (y) a tender offer or exchange offer for shares of Common Stock, as to which Section 5.05(A)(v) will apply), and such Capital Stock or equity interests are 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:

where:

CR0	=	the<br>Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Spin-Off Valuation Period for such Spin-Off;
CR1	=	the<br>Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Spin-Off Valuation Period;
FMV	=	the product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital<br>Stock or equity interests distributed in such Spin-Off over the ten (10) consecutive Trading Day period (the “Spin-Off ValuationPeriod”) beginning on, and including, the Ex-Dividend Date for such Spin-Off (such average to be determined as if references<br>to Common Stock in the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event were instead references to such<br>Capital Stock or equity interests); and (y) the number of shares or units of such Capital Stock or equity interests distributed per<br>share of Common Stock in such Spin-Off; and
SP	=	the average of the Last Reported Sale Prices per share of Common Stock for each Trading Day in the<br>Spin-Off Valuation Period.

- 52 -

Notwithstanding anything to the contrary in this Section 5.05(A)(iii)(2), (i) if any VWAP Trading Day of the Observation Period for a Note whose Conversion will be settled pursuant to Cash Settlement or Combination Settlement occurs during the Spin-Off Valuation Period for such Spin-Off, then, solely for purposes of determining the Conversion Rate for such VWAP Trading Day for such Conversion, such Spin-Off Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Ex-Dividend Date for such Spin-Off to, and including, such VWAP Trading Day; and (ii) if the Conversion Date for a Note whose Conversion will be settled pursuant to Physical Settlement occurs during the Spin-Off Valuation Period for such Spin-Off, then, solely for purposes of determining the Conversion Consideration for such Conversion, such Spin-Off Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Ex-Dividend Date for such Spin-Off to, and including, such Conversion Date.

To the extent any dividend or distribution of the type set forth in this Section 5.05(A)(iii)(2) is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

(iv)          CashDividends 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:

where:

CR0	=	the Conversion Rate in effect immediately before 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 such Ex-Dividend Date;
SP	=	the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before such Ex-Dividend Date; and
D	=	the cash amount distributed per share of Common Stock in such dividend or distribution;

- 53 -

provided, however, that if D is equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate, each Holder will receive, for each $1,000 principal amount of Notes held by such Holder on the record date for such dividend or distribution, at the same time and on the same terms as holders of Common Stock, the amount of cash that such Holder would have received in such dividend or distribution if such Holder had owned, on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

(v)          TenderOffers 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 (other than solely pursuant to an odd-lot tender offer pursuant to Rule 13e-4(h)(5) under the Exchange Act), and the value (determined as of the Expiration Time by the Company in good faith and in a commercially reasonable manner) 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:

where:

CR0	=	the Conversion Rate in effect immediately before the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation<br>Period for such tender or exchange offer;
CR1	=	the Conversion Rate in effect immediately after the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period;
AC	=	the aggregate value (determined as of the time (the “Expiration Time”) such tender<br>or exchange offer expires by the Company in good faith and in a commercially reasonable manner) of all cash and other consideration paid<br>for shares of Common Stock purchased or exchanged in such tender or exchange offer;
OS0	=	the number of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock accepted<br>for purchase or exchange in such tender or exchange offer);
OS1	=	the number of shares of Common Stock outstanding immediately after the Expiration Time (excluding all shares of Common Stock accepted<br>for purchase or exchange in such tender or exchange offer); and
SP	=	the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive<br>Trading Day period (the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading Day immediately<br>after the Expiration Date;

- 54 -

provided, however, that the Conversion Rate will in no event be adjusted down pursuant to this Section 5.05(A)(v), except to the extent provided in the immediately following paragraph. Notwithstanding anything to the contrary in this Section 5.05(A)(v), (i) if any VWAP Trading Day of the Observation Period for a Note whose Conversion will be settled pursuant to Cash Settlement or Combination Settlement occurs during the Tender/Exchange Offer Valuation Period for such tender or exchange offer, then, solely for purposes of determining the Conversion Rate for such VWAP Trading Day for such Conversion, such Tender/Exchange Offer Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Trading Day immediately after the Expiration Date for such tender or exchange offer to, and including, such VWAP Trading Day; and (ii) if the Conversion Date for a Note whose Conversion will be settled pursuant to Physical Settlement occurs during the Tender/Exchange Offer Valuation Period for such tender or exchange offer, then, solely for purposes of determining the Conversion Consideration for such Conversion, such Tender/Exchange Offer Valuation Period will be deemed to consist of the Trading Days occurring in the period from, and including, the Trading Day immediately after the Expiration Date to, and including, such Conversion Date.

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

(B)          NoAdjustments in Certain Cases.

(i)            WhereHolders Participate in the Transaction or Event Without Conversion. Notwithstanding anything to the contrary in Section 5.05(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 5.05(A) (other than a stock split or combination of the type set forth in Section 5.05(A)(i) or a tender or exchange offer of the type set forth in Section 5.05(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; and (ii) the aggregate principal amount (expressed in thousands) of Notes held by such Holder on such date.

- 55 -

(ii)           CertainEvents. The Company will not be required to adjust the Conversion Rate except as provided in Section 5.05 or Section 5.07. 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 5.05, 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 outstanding as of the Issue Date;

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

(6)          accrued and unpaid interest, if any, on the Notes.

(C)          AdjustmentDeferral. If an adjustment to the Conversion Rate otherwise required by this Article 5 would result in a change of less than one percent (1%) to the Conversion Rate, then, notwithstanding anything to the contrary in this Article 5, the Company may, at its election, defer such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest of the following: (i) when all such deferred adjustments would result in a change of at least one percent (1%) to the Conversion Rate; (ii) the Conversion Date of, or any VWAP Trading Day of an Observation Period for, any Note; (iii) the date a Fundamental Change or Make-Whole Fundamental Change occurs; (iv) the date the Company calls any Notes for Redemption; and (v) August 15, 2031.

(D)          AdjustmentsNot Yet Effective. Notwithstanding anything to the contrary in this Indenture or the Notes, if:

(i)            a Note is to be Converted pursuant to Physical Settlement or Combination Settlement;

- 56 -

(ii)           the record date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to Section 5.05(A) has occurred on or before the Conversion Date for such Conversion (in the case of Physical Settlement) or on or before any VWAP Trading Day in the Observation Period for such Conversion (in the case of Combination Settlement), but an adjustment to the Conversion Rate for such event has not yet become effective as of such Conversion Date or VWAP Trading Day, as applicable;

(iii)          the Conversion Consideration due upon such Conversion includes any whole shares of Common Stock (in the case of Physical Settlement) or due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement); and

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

then, solely for purposes of such Conversion, the Company will, without duplication, give effect to such adjustment on such Conversion Date (in the case of Physical Settlement) or such VWAP Trading Day (in the case of Combination Settlement). In such case, if the date on which the Company is otherwise required to deliver the consideration due upon such Conversion is before the first date on which the amount of such adjustment can be determined, then the Company will delay the settlement of such Conversion until the second (2nd) Business Day after such first date.

(E)          ConversionRate 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 5.05(A);

(ii)           a Note is to be Converted pursuant to Physical Settlement or Combination Settlement;

(iii)          the Conversion Date for such Conversion (in the case of Physical Settlement) or any VWAP Trading Day in the Observation Period for such Conversion (in the case of Combination Settlement) 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 (in the case of Physical Settlement) or due in respect of such VWAP Trading Day includes any whole or fractional shares of Common Stock (in the case of Combination Settlement), in each case based on a Conversion Rate that is adjusted for such dividend or distribution; and

- 57 -

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

then (x) in the case of Physical Settlement, such Conversion Rate adjustment will not be given effect for such Conversion and the shares of Common Stock issuable upon such Conversion based on such unadjusted Conversion Rate will not be entitled to participate in such dividend or distribution, but there will be added, without duplication, to the Conversion Consideration otherwise due upon such Conversion, the same kind and amount of consideration that would have been delivered in such dividend or distribution with respect to such shares of Common Stock had such shares been entitled to participate in such dividend or distribution; and (y) in the case of Combination Settlement, the Conversion Rate adjustment relating to such Ex-Dividend Date will be made for such Conversion in respect of such VWAP Trading Day, but the shares of Common Stock issuable with respect to such VWAP Trading Day based on such adjusted Conversion Rate will not be entitled to participate in such dividend or distribution.

(F)          StockholderRights 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 5.05(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 as described in the last paragraph of Section 5.05(A)(iii)(1) if such rights expire, terminate or are redeemed.

(G)           Limitationon 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 5.05(A) or Section 5.07 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.

(H)          EquitableAdjustments to Prices. Whenever any provision of this Indenture requires the Company to calculate the average of the Last Reported Sale Prices, or any function thereof, over a period of multiple days (including to calculate the Stock Price or an adjustment to the Conversion Rate), or to calculate Daily VWAPs over an Observation Period, the Company will make proportionate adjustments to those calculations to account for any adjustment to the Conversion Rate pursuant to Section 5.05(A) 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 or Observation Period, as applicable.

(I)            Calculationof Number of Outstanding Shares of Common Stock. For purposes of Section 5.05(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).

- 58 -

(J)            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).

(K)          Noticeof Conversion Rate Adjustments. Upon the effectiveness of any adjustment to the Conversion Rate pursuant to Section 5.05(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 5.06.**VoluntaryAdjustments.

(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)          Noticeof Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant to Section 5.06(A), then, no later than the first Business Day of the related twenty (20) Business Day period referred to in Section 5.06(A), 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 5.07.**Adjustmentsto the Conversion Rate in Connection with a Make-Whole Fundamental Change.

(A)          Generally. If a Make-Whole Fundamental Change occurs 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 5.07, 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 Make-Whole Fundamental Change Effective Date and the Stock Price of such Make-Whole Fundamental Change:

	Stock Price
Make-Whole<br><br> Fundamental<br><br> Change Effective<br><br><br> Date	16.85	18.00	20.00	23.17	25.00	30.12	35.00	40.00	50.00	75.00	100.00	150.00
May 7,<br> 2026
November 15,<br> 2026
November 15,<br> 2027
November 15,<br> 2028
November 15,<br> 2029
November 15,<br> 2030
November 15,<br> 2031

All values are in US Dollars.

- 59 -

If such Make-Whole Fundamental Change Effective Date or Stock Price is not set forth in the table above, then:

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

(ii)           if the Stock Price is greater than $150.00 (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 5.07(B)), or less than $16.85 (subject to adjustment in the same manner), per share, then no Additional Shares will be added to the Conversion Rate.

Notwithstanding anything to the contrary in this Indenture or the Notes, in no event will the Conversion Rate be increased to an amount that exceeds 59.3471 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is required to be adjusted pursuant to Section 5.05(A).

For the avoidance of doubt, but subject to Section 4.03(I), (x) the sending of a Redemption Notice will constitute a Make-Whole Fundamental Change only with respect to the Notes called (or deemed called pursuant to Section 4.03(I)) for Redemption pursuant to such Redemption Notice, and not with respect to any other Notes; and (y) the Conversion Rate applicable to the Notes not so called for Redemption will not be subject to increase pursuant to this Section 5.07 on account of such Redemption Notice.

(B)          Adjustmentof Stock Prices and Number of Additional Shares. The Stock Prices in the first row (i.e., the column headers) of the table set forth in Section 5.07(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 5.05(A). The numbers of Additional Shares in the table set forth in Section 5.07(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 5.05(A).

(C)          Noticeof the Occurrence of a Make-Whole Fundamental Change. The Company will notify the Holders, the Trustee and the Conversion Agent of each Make-Whole Fundamental Change (i) occurring pursuant to clause (A) of the definition thereof in accordance with Section 5.01(C)(i)(3)(b); and (ii) occurring pursuant to clause (B) of the definition thereof in accordance with Section 4.03(F).

**Section 5.08.**Exchangein Lieu of Conversion.

Notwithstanding anything to the contrary in this Article 5, and subject to the terms of this Section 5.08, if a Note is submitted for Conversion, the Company may elect to arrange to have such Note exchanged in lieu of Conversion by a financial institution designated by the Company. To make such election, the Company must send notice of such election to the Holder of such Note, the Trustee and the Conversion Agent before the Close of Business on the Business Day immediately following the Conversion Date for such Note. If the Company has made such election, then:

(A)          no later than the Business Day immediately following such Conversion Date, the Company must deliver (or cause the Conversion Agent to deliver) such Note, together with delivery instructions for the Conversion Consideration due upon such Conversion (including wire instructions, if applicable), to a financial institution designated by the Company that has agreed to deliver such Conversion Consideration in the manner and at the time the Company would have had to deliver the same pursuant to this Article 5;

- 60 -

(B)          if such Note is a Global Note, then (i) such designated institution will send written confirmation to the Conversion Agent promptly after wiring the cash Conversion Consideration, if any, and delivering any other Conversion Consideration, due upon such Conversion to the Holder of such Note; and (ii) the Conversion Agent will as soon as reasonably practicable thereafter contact such Holder’s custodian with the Depositary to confirm receipt of the same; and

provided, however, that if such financial institution does not accept such Note or fails to timely deliver such Conversion Consideration, then the Company will be responsible for delivering such Conversion Consideration in the manner and at the time provided in this Article 5 as if the Company had not elected to make an exchange in lieu of Conversion.

**Section 5.09.**Effectof 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 and (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,

and, as a result of which, the Common Stock is converted into, or is exchanged for, or represents solely the right to receive, other securities, cash or other property, or any combination of the foregoing (such an event, a “Common Stock Change Event,” and such other securities, cash or property, the “ReferenceProperty,” and the amount and kind of Reference Property that a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement not to issue or deliver a fractional portion of any security or other property), a “Reference Property Unit”), then, notwithstanding anything to the contrary in this Indenture or the Notes,

(1)           from and after the effective time of such Common Stock Change Event, (I) the Conversion Consideration due upon Conversion of any Note, and the conditions to any such Conversion, will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 5 (or in any related definitions) were instead a reference to the same number of Reference Property Units; (II) for purposes of Section 4.03, each reference to any number of shares of Common Stock in such Section (or in any related definitions) will instead be deemed to be a reference to the same number of Reference Property Units; and (III) for purposes of the definitions of “Fundamental Change” and “Make-Whole Fundamental Change” the terms “Common Stock” and the Company’s “common equity” will be deemed to mean the common equity (including depositary receipts representing common equity), if any, forming part of such Reference Property;

- 61 -

(2)           if such Reference Property Unit consists entirely of cash, then the Company will be deemed to elect Physical Settlement in respect of all Conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event and will pay the cash due upon such Conversions no later than the second (2nd) Business Day after the relevant Conversion Date; and

(3)            for these purposes, (I) the Daily VWAP of any Reference Property Unit or portion thereof that consists of a class of common equity securities will be determined by reference to the definition of “Daily VWAP,” substituting, if applicable, the Bloomberg page for such class of securities in such definition; and (II) the Daily VWAP of any Reference Property Unit or portion thereof that does not consist of a class of common equity securities, and the Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities, will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof).

If the Reference Property consists of more than a single type of consideration to be determined based in part upon any form of stockholder election, then the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration actually received, per share of Common Stock, by the holders of Common Stock. The Company will notify Holders, the Trustee and the Conversion Agent of such weighted average as soon as practicable after such determination is made.

Subject to the last sentence of this paragraph, at or before the effective time of such Common Stock Change Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the “Successor Person”) will execute and deliver to the Trustee a supplemental indenture pursuant to Section 8.01(F), which supplemental indenture will (x) provide for subsequent Conversions of Notes in the manner set forth in this Section 5.09; (y) provide for subsequent adjustments to the Conversion Rate pursuant to Section 5.05(A) in a manner consistent with this Section 5.09; and (z) contain such other provisions, if any, that the Company reasonably determines are appropriate to preserve the economic interests of the Holders and to give effect to the provisions of this Section 5.09(A). If the Reference Property includes shares of stock or other securities or assets (other than cash) of a Person other than the Successor Person, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain such additional provisions, if any, that the Company reasonably determines are appropriate to preserve the economic interests of the Holders. Notwithstanding anything to the contrary in this paragraph, no such supplemental indenture is required (but the Company may nonetheless choose to execute such a supplemental indenture at its option) if (i) the Company is the resulting, surviving or transferee Person of such Common Stock Change Event; and (ii) the Reference Property of such Common Stock Change Event does not include consideration other than cash or securities of the Company.

- 62 -

(B)          Noticeof 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 second (2nd) Business Day after the effective date of such Common Stock Change Event.

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

**Article 6.**Successors

**Section 6.01.**Whenthe Company May Merge, Etc.

(A)          Generally. The Company will not consolidate with or merge with or into, or (directly, or indirectly through one or more of its Subsidiaries) sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to another Person (a “Business Combination Event”), unless:

(i)            the resulting, surviving or transferee Person either (x) is the Company or (y) if not the Company, is a Qualified Successor Entity (such Qualified Successor Entity, the “Successor Entity”) duly organized and existing under the laws of the United States of America, any State thereof or the District of Columbia that expressly assumes (by executing and delivering to the Trustee, at or before the effective time of such Business Combination Event, a supplemental indenture pursuant to Section 8.01(E)) all of the Company’s obligations under this Indenture and the Notes; and

(ii)           immediately after giving effect to such Business Combination Event, no Default will have occurred and be continuing.

(B)          Deliveryof Officer’s Certificate and Opinion of Counsel to the Trustee. At or before the effective time of any Business Combination Event, the Company will deliver to the Trustee an Officer’s Certificate and Opinion of Counsel, each stating that (i) such Business Combination Event (and, if applicable, the related supplemental indenture) comply with Section 6.01(A); and (ii) all conditions precedent to such Business Combination Event provided in this Indenture have been satisfied.

- 63 -

**Section 6.02.**SuccessorEntity Substituted.

At the effective time of any Business Combination Event that complies with Section 6.01, the Successor Entity (if not the Company) will succeed to, and may exercise every right and power of, the Company under this Indenture and the Notes with the same effect as if such Successor Entity had been named as the Company in this Indenture and the Notes, and, except in the case of a lease, the predecessor Company will be discharged from its obligations under this Indenture and the Notes.

**Article 7.**Defaultsand Remedies

**Section 7.01.**Eventsof Default.

(A)          Definitionof Events of Default. “Event of Default” means the occurrence of any of the following:

(i)            a default in the payment when due (whether at maturity, upon Redemption or Repurchase Upon Fundamental Change or otherwise) of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, any Note;

(ii)           a default for thirty (30) consecutive days in the payment when due of any Special Interest or Additional Interest that has accrued on any Note;

(iii)          the Company’s failure to deliver, when required by this Indenture, a Fundamental Change Notice, or a notice pursuant to Section 5.01(C)(i)(3) if (in the case of any notice other than a notice pursuant to Section 5.01(C)(i)(3)) such failure is not cured within five (5) Business Days after its occurrence;

(iv)          a default in the Company’s obligation to Convert a Note in accordance with Article 5 upon the exercise of the Conversion right with respect thereto, if such default is not cured within five (5) Business Days after its occurrence;

(vi)          a default in any of the Company’s obligations or agreements under the Notes or under this Indenture with respect to the Notes (other than a default set forth in clause (i), (ii), (iii), (iv) or (v) of this Section 7.01(A)) where such default is not cured or waived within sixty (60) days after notice to the Company by the Trustee, or to the Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, which notice must specify such default, demand that it be remedied and state that such notice is a “Notice of Default”;

(vii)         a default by the Company or any of the Company’s Significant Subsidiaries with respect to any one or more mortgages, agreements or other instruments under which there is outstanding, or by which there is secured or evidenced, any indebtedness for money borrowed of at least fifty million dollars ($50,000,000) (or its foreign currency equivalent) in the aggregate of the Company or any of the Company’s Significant Subsidiaries, whether such indebtedness exists as of the Issue Date or is thereafter created, where such default:

(1)          constitutes a failure to pay the principal of such indebtedness when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, in each case after the expiration of any applicable grace period; or

- 64 -

(2)          results in such indebtedness becoming or being declared due and payable before its stated maturity,

in each case where such default is not cured or waived within thirty (30) days after notice to the Company by the Trustee or to the Company and the Trustee by Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding; and

(viii)        the Company or any of its Significant Subsidiaries, pursuant to or within the meaning of any Bankruptcy Law, either:

(1)          commences a voluntary case or proceeding;

(2)          consents to the entry of an order for relief against it in an involuntary case or proceeding;

(3)          orders the winding up or liquidation of the Company or any of its Significant Subsidiaries; or

(4)          grants any similar relief under any foreign Bankruptcy Law,

and, in each case under this Section 7.01(A)(ix), such order or decree remains unstayed and in effect for at least sixty (60) days.

- 65 -

(B)          CauseIrrelevant. Each of the events set forth in Section 7.01(A) will constitute an Event of Default regardless of the cause thereof or whether voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

**Section 7.02.**Acceleration.

(A)          AutomaticAcceleration in Certain Circumstances. If an Event of Default set forth in Section 7.01(A)(viii) or 7.01(A)(ix) occurs with respect to the Company (and not solely with respect to a Significant Subsidiary of the Company), then the principal amount of, and all accrued and unpaid interest, if any, on, all of the Notes then outstanding will immediately become due and payable without any further action or notice by any Person.

(B)          OptionalAcceleration. Subject to Section 7.03, if an Event of Default (other than an Event of Default set forth in Section 7.01(A)(viii) or 7.01(A)(ix) with respect to the Company and not solely with respect to a Significant Subsidiary of the Company) occurs and is continuing, then the Trustee, by notice to the Company, or Holders of at least twenty five percent (25%) of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest, if any, on, all of the Notes then outstanding to become due and payable immediately. For the avoidance of doubt, if such Event of Default is not continuing at the time such notice is provided (that is, such Event of Default has been cured or waived as of such time), then such notice will not be effective to cause such amounts to become due and payable immediately.

(C)          Rescissionof Acceleration. Notwithstanding anything to the contrary in this Indenture or the Notes, the Holders of a majority in aggregate principal amount of the Notes then outstanding, by notice to the Company and the Trustee, may, on behalf of all Holders, rescind any acceleration of the Notes and its consequences if (i) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (ii) all existing Events of Default (except the non-payment of principal of, or interest, if any, on, the Notes that has become due solely because of such acceleration) have been cured or waived. No such rescission will affect any subsequent Default or impair any right consequent thereto.

**Section 7.03.**SoleRemedy for a Failure to Report.

(A)          Generally. Notwithstanding anything to the contrary in this Indenture or the Notes, the Company may elect that the sole remedy for any Event of Default (a “Reporting Event of Default”) pursuant to Section 7.01(A)(vi) arising from the Company’s failure to comply with Section 3.02 will, for each of the first three hundred sixty five (365) calendar days on which a Reporting Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the Notes. If the Company has made such an election, then (i) the Notes will be subject to acceleration pursuant to Section 7.02 on account of the relevant Reporting Event of Default from, and including, the three hundred sixty sixth (366th) calendar day on which a Reporting Event of Default has occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due; and (ii) Special Interest will cease to accrue on any Notes from, and including, such three hundred sixty sixth (366th) calendar day (it being understood that interest on any defaulted Special Interest will nonetheless accrue pursuant to Section 2.05(B)).

- 66 -

(B)          Amountand Payment of Special Interest. Any Special Interest that accrues on a Note pursuant to Section 7.03(A) will accrue at a rate per annum equal to one quarter of one percent (0.25%) of the principal amount thereof for the first one hundred eighty (180) days on which Special Interest accrues and, thereafter, at a rate per annum equal to one half of one percent (0.50%) of the principal amount thereof; provided, however, that in no event will Special Interest, together with any Additional Interest, accrue on any day on a Note at a combined rate per annum that exceeds one half of one percent (0.50%). For the avoidance of doubt, any Special Interest that accrues on a Note will, subject to the proviso of the immediately preceding sentence, be in addition to any Additional Interest that accrues on such Note.

(C)          Noticeof Election. To make the election set forth in Section 7.03(A), the Company must send to the Holders, the Trustee and the Paying Agent, before the date on which each Reporting Event of Default first occurs, a notice that (i) briefly describes the report(s) that the Company failed to file with the SEC; (ii) states that the Company is electing that the sole remedy for such Reporting Event of Default consist of the accrual of Special Interest; and (iii) briefly describes the periods during which and rate at which Special Interest will accrue and the circumstances under which the Notes will be subject to acceleration on account of such Reporting Event of Default.

(D)          Noticeto Trustee and Paying Agent; Trustee’s Disclaimer. If Special Interest accrues on any Note, then, no later than five (5) Business Days before each date on which such Special Interest is to be paid, the Company will deliver an Officer’s Certificate to the Trustee and the Paying Agent stating (i) that the Company is obligated to pay Special Interest on such Note on such date of payment; and (ii) the amount of such Special Interest that is payable on such date of payment. The Trustee will have no duty to determine whether any Special Interest is payable or the amount thereof.

(E)          NoEffect on Other Events of Default. No election pursuant to this Section 7.03 with respect to a Reporting Event of Default will affect the rights of any Holder with respect to any other Event of Default.

**Section 7.04.**OtherRemedies.

(A)          TrusteeMay Pursue All Remedies. If an Event of Default occurs and is continuing, then the Trustee may pursue any available remedy to collect the payment of any amounts due with respect to the Notes or to enforce the performance of any provision of this Indenture or the Notes.

(B)          ProceduralMatters. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in such proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy following an Event of Default will not impair the right or remedy or constitute a waiver of, or acquiescence in, such Event of Default. All remedies will be cumulative to the extent permitted by law.

- 67 -

**Section 7.05.**Waiverof Past Defaults.

A Default that is (or, after notice, passage of time or both, would be) an Event of Default pursuant to clause (i), (ii), (iv) or (vi) of Section 7.01(A) (that, in the case of clause (vi) only, results from a Default under any covenant that cannot be amended without the consent of each affected Holder) can be waived only with the consent of each affected Holder. Each other Default may be waived, on behalf of all Holders, by the Holders of a majority in aggregate principal amount of the Notes then outstanding. If an Event of Default is so waived, then it will cease to exist. If a Default is so waived, then it will be deemed to be cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or other Default or impair any right arising therefrom. Each such waiver of a Default will have the effect set forth in Section 8.04(D).

**Section 7.06.**Cureof Defaults; Ability to Cure or Waive Before Event of Default Occurs.

For the avoidance of doubt, and without limiting the manner in which any Default can be cured, (A) a Default consisting of a failure to send a notice in accordance with this Indenture will be cured upon the sending of such notice; (B) a Default in making any payment on (or delivering any other consideration in respect of) any Note will be cured upon the delivery, in accordance with this Indenture, of such payment (or other consideration) together, if applicable, with Default Interest thereon; and (C) a Default that is (or, after notice, passage of time or both, would be) a Reporting Event of Default will be cured upon the filing of the relevant report(s) giving rise to such Default. In addition, for the avoidance of doubt, if a Default that is not an Event of Default is cured or waived before such Default would have constituted an Event of Default, then no Event of Default will result from such Default.

**Section 7.07.**Controlby Majority.

Holders of a majority in aggregate principal amount of the Notes then outstanding may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law, this Indenture or the Notes, or that, subject to Section 10.01, the Trustee determines may be unduly prejudicial to the rights of other Holders (it being understood the Trustee does not have an affirmative duty to determine whether any direction is prejudicial to any Holder) or may involve the Trustee in liability. Prior to taking any action under this Indenture or the Notes, the Trustee will be entitled to security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such direction.

**Section 7.08.**Limitationon Suits.

No Holder may pursue any remedy with respect to this Indenture or the Notes (except to enforce (x) its rights to receive the principal of, or the Fundamental Change Repurchase Price or Redemption Price for, or interest, if any, on, any Notes; or (y) the Company’s obligations to Convert any Notes pursuant to Article 5), unless:

(A)          such Holder has previously delivered to the Trustee notice that an Event of Default is continuing;

- 68 -

(B)          Holders of at least twenty five percent (25%) in aggregate principal amount of the Notes then outstanding deliver a request to the Trustee to pursue such remedy;

(C)          such Holder or Holders offer and, if requested, provide to the Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense to the Trustee that may result from the Trustee’s following such request;

(D)          the Trustee does not comply with such request within sixty (60) calendar days after its receipt of such request and such offer of security or indemnity; and

(E)          during such sixty (60) calendar day period, Holders of a majority in aggregate principal amount of the Notes then outstanding do not deliver to the Trustee a direction that is inconsistent with such request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. The Trustee will have no duty to determine whether any Holder’s use of this Indenture complies with the preceding sentence.

**Section 7.09.**AbsoluteRight of Holders to Institute Suit for the Enforcement of the Right to Receive Payment and Conversion Consideration.

Notwithstanding anything to the contrary in this Indenture or the Notes (but without limiting Section 8.01), the right of each Holder of a Note to bring suit for the enforcement of any payment or delivery, as applicable, of the principal of, or the Redemption Price or Fundamental Change Repurchase Price for, or any interest on, or the Conversion Consideration due pursuant to Article 5 upon Conversion of, such Note on or after the respective due dates therefor provided in this Indenture and the Notes, or to bring suit for the enforcement of any such payment or delivery on or after such respective due dates, will not be impaired or affected without the consent of such Holder.

**Section 7.10.**CollectionSuit by Trustee.

The Trustee will have the right, upon the occurrence and continuance of an Event of Default pursuant to clause (i), (ii) or (iv) of Section 7.01(A), to recover judgment in its own name and as trustee of an express trust against the Company for the total unpaid or undelivered principal of, or Fundamental Change Repurchase Price or Redemption Price for, or interest, if any, on, or Conversion Consideration due pursuant to Article 5 upon Conversion of, the Notes, as applicable, and, to the extent lawful, any Default Interest on any Defaulted Amounts, and such further amounts sufficient to cover the costs and expenses of collection, including compensation provided for in Section 10.06.

- 69 -

**Section 7.11.**TrusteeMay File Proofs of Claim.

The Trustee has the right to (A) 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 (or any other obligor upon the Notes) or its creditors or property and (B) collect, receive and distribute any money or other property payable or deliverable on any such claims. Each Holder authorizes any custodian in such proceeding to make such payments to the Trustee, and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to the Trustee for the reasonable compensation, expenses, disbursements and advances of the Trustee, and its agents and counsel, and any other amounts payable to the Trustee pursuant to Section 10.06. To the extent that the payment of any such compensation, expenses, disbursements, advances and other amounts out of the estate in such proceeding, is denied for any reason, payment of the same will be secured by a lien (senior to the rights of Holders) on, and will be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding (whether in liquidation or under any plan of reorganization or arrangement or otherwise). Nothing in this Indenture will be deemed to authorize the Trustee to authorize, consent to, accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

**Section 7.12.**Priorities.

The Trustee will pay or deliver in the following order any money or other property that it collects pursuant to this Article 7:

First:      to the Trustee and its agents and attorneys for amounts due under Section 10.06, including payment of all fees and compensation of, and all expenses and liabilities incurred, and all advances made, by, the Trustee (in each of its capacities under this Indenture, including as Note Agent) and the costs and expenses of collection;

Second:      to Holders for unpaid amounts or other property due on the Notes, including the principal of, or the Fundamental Change Repurchase Price or Redemption Price for, or any interest on, or any Conversion Consideration due upon Conversion of, the Notes, ratably, and without preference or priority of any kind, according to such amounts or other property due and payable on all of the Notes; and

Third:      to the Company or such other Person as a court of competent jurisdiction directs.

The Trustee may fix a record date and payment date for any payment or delivery to the Holders pursuant to this Section 7.12, in which case the Trustee will instruct the Company to, and the Company will, deliver, at least fifteen (15) calendar days before such record date, to each Holder and the Trustee a notice stating such record date, such payment date and the amount of such payment or nature of such delivery, as applicable.

- 70 -

**Section 7.13.**Undertakingfor Costs.

In any suit for the enforcement of any right or remedy under this Indenture or the Notes or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court, in its discretion, may (A) require the filing by any litigant party in such suit of an undertaking to pay the costs of such suit; and (B) assess reasonable costs (including reasonable attorneys’ fees) against any litigant party in such suit, having due regard to the merits and good faith of the claims or defenses made by such litigant party; provided, however, that this Section 7.13 does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section 7.09 or any suit by one or more Holders of more than ten percent (10%) in aggregate principal amount of the Notes then outstanding.

**Article 8.**Amendments,Supplements and Waivers

(A)          Generally. Subject to Sections 8.01, 7.05 and 7.09 and the immediately following sentence, the Company and the Trustee may, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding, amend or supplement this Indenture or the Notes or waive compliance with any provision of this Indenture or the Notes. Notwithstanding anything to the contrary in the foregoing sentence, but subject to Section 8.01, without the consent of each affected Holder, no amendment or supplement to this Indenture or the Notes, or waiver of any provision of this Indenture or the Notes, may:

(i)            reduce the principal, or extend the stated maturity, of any Note;

(B)          HoldersNeed Not Approve the Particular Form of any Amendment. A consent of any Holder pursuant to this Section 8.02 need approve only the substance, and not necessarily the particular form, of the proposed amendment, supplement or waiver.

- 72 -

**Section 8.03.**Noticeof Amendments, Supplements and Waivers.

As soon as reasonably practicable after any amendment, supplement or waiver pursuant to Section 8.01 or 8.02 becomes effective, the Company will send to the Holders and the Trustee notice that (A) describes the substance of such amendment, supplement or waiver in reasonable detail and (B) states the effective date thereof; provided, however, that the Company will not be required to provide such notice to the Holders if such amendment, supplement or waiver is included in a periodic report filed by the Company with the SEC within four (4) Business Days of its effectiveness. The failure to send, or the existence of any defect in, such notice will not impair or affect the validity of such amendment, supplement or waiver.

**Section 8.04.**Revocation,Effect and Solicitation of Consents; Special Record Dates; Etc.

(A)          Revocationand Effect of Consents. The consent of a Holder of a Note to an amendment, supplement or waiver will bind (and constitute the consent of) each subsequent Holder of any Note to the extent the same evidences any portion of the same indebtedness as the consenting Holder’s Note, subject to the right of any Holder of a Note to revoke (if not prohibited pursuant to Section 8.04(B)) any such consent with respect to such Note by delivering notice of revocation to the Trustee before the time such amendment, supplement or waiver becomes effective.

(B)          SpecialRecord Dates. The Company may, but is not required to, fix a record date for the purpose of determining the Holders entitled to consent or take any other action in connection with any amendment, supplement or waiver pursuant to this Article 8. If a record date is fixed, then, notwithstanding anything to the contrary in Section 8.04(A), only Persons who are Holders as of such record date (or their duly designated proxies) will be entitled to give such consent, to revoke any consent previously given or to take any such action, regardless of whether such Persons continue to be Holders after such record date; provided, however, that no such consent will be valid or effective for more than one hundred and twenty (120) calendar days after such record date.

(C)          Solicitationof Consents. For the avoidance of doubt, each reference in this Indenture or the Notes to the consent of a Holder will be deemed to include any such consent obtained in connection with a repurchase of, or tender or exchange offer for, any Notes.

(D)          Effectivenessand Binding Effect. Each amendment or supplement to this Indenture or the Notes, or waiver of any Default, Event of Default or compliance with any provision of this Indenture or the Notes, will become effective in accordance with its terms and, when it becomes effective with respect to any Note (or any portion thereof), will thereafter bind every Holder of such Note (or such portion).

**Section 8.05.**Notationsand Exchanges.

If any amendment, supplement or waiver changes the terms of a Note, then the Trustee or the Company may, in its discretion, require the Holder of such Note to deliver such Note to the Trustee so that the Trustee may place an appropriate notation prepared by the Company on such Note and return such Note to such Holder. Alternatively, at its discretion, the Company may, in exchange for such Note, issue, execute and deliver, and the Trustee will authenticate, in each case in accordance with Section 2.02, a new Note that reflects the changed terms. The failure to make any appropriate notation or issue a new Note pursuant to this Section 8.05 will not impair or affect the validity of such amendment, supplement or waiver.

- 73 -

**Section 8.06.**Trusteeto Execute Supplemental Indentures.

The Trustee will execute and deliver any amendment or supplemental indenture authorized pursuant to this Article 8; provided, however, that the Trustee need not (but may, in its sole and absolute discretion) execute or deliver any such amendment or supplemental indenture that the Trustee concludes adversely affects the Trustee’s rights, duties, liabilities or immunities. In executing any amendment or supplemental indenture, the Trustee will be entitled to receive, and (subject to Sections 10.01 and 10.02) will be fully protected in relying on, an Officer’s Certificate and an Opinion of Counsel stating that (A) the execution and delivery of such amendment or supplemental indenture is authorized or permitted by this Indenture; and (B) in the case of the Opinion of Counsel, such amendment or supplemental indenture is valid, binding and enforceable against the Company in accordance with its terms.

**Article 9.**Satisfactionand Discharge

**Section 9.01.**Terminationof Company’s Obligations.

(A)          all Notes then outstanding (other than Notes replaced pursuant to Section 2.13) have (i) been delivered to the Trustee for cancellation; or (ii) become due and payable (whether on a Redemption Date, a Fundamental Change Repurchase Date, the Maturity Date, upon Conversion or otherwise) for an amount of cash or Conversion Consideration, as applicable, that has been fixed;

(B)          the Company has caused there to be irrevocably deposited with the Trustee, or with the Paying Agent (or, with respect to Conversion Consideration, the Conversion Agent), in each case for the benefit of the Holders, or has otherwise caused there to be delivered to the Holders, cash (or, with respect to Notes to be Converted, Conversion Consideration) sufficient to satisfy all amounts or other property due on all Notes then outstanding (other than Notes replaced pursuant to Section 2.13);

(D)          the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that the conditions precedent to the discharge of this Indenture have been satisfied;

provided, however, that Article 10 and Section 11.01 will survive such discharge and, until no Notes remain outstanding, Section 2.15 and the obligations of the Trustee, the Paying Agent and the Conversion Agent with respect to money or other property deposited with them will survive such discharge.

- 74 -

At the Company’s request, the Trustee will acknowledge the satisfaction and discharge of this Indenture.

**Section 9.02.**Repaymentto Company.

Subject to applicable unclaimed property law, the Trustee, the Paying Agent and the Conversion Agent will promptly notify the Company if there exists (and, at the Company’s request, promptly deliver to the Company) any cash, Conversion Consideration or other property held by any of them for payment or delivery on the Notes that remain unclaimed two (2) years after the date on which such payment or delivery was due. After such delivery to the Company, the Trustee, the Paying Agent and the Conversion Agent will have no further liability to any Holder with respect to such cash, Conversion Consideration or other property, and Holders entitled to the payment or delivery of such cash, Conversion Consideration or other property must look to the Company for payment as a general creditor of the Company.

**Section 9.03.**Reinstatement.

If the Trustee, the Paying Agent or the Conversion Agent is unable to apply any cash or other property deposited with it pursuant to Section 9.01 because of any legal proceeding or any order or judgment of any court or other governmental authority that enjoins, restrains or otherwise prohibits such application, then the discharge of this Indenture pursuant to Section 9.01 will be rescinded; provided, however, that if the Company thereafter pays or delivers any cash or other property due on the Notes to the Holders thereof, then the Company will be subrogated to the rights of such Holders to receive such cash or other property from the cash or other property, if any, held by the Trustee, the Paying Agent or the Conversion Agent, as applicable.

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

(i)            the duties of the Trustee will be determined solely by the express provisions of this Indenture, and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations will be read into this Indenture against the Trustee; and

(ii)           in the absence of gross negligence or willful misconduct on its part, the Trustee may, without investigation, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon Officer’s Certificates or Opinions of Counsel that are provided to the Trustee and conform to the requirements of this Indenture; provided, however, that the Trustee will examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

- 75 -

(C)          The Trustee may not be relieved from liabilities for its gross negligence or willful misconduct, except that:

(i)            this paragraph will not limit the effect of Section 10.01(B);

(F)          The Trustee will not be liable in its individual capacity for the obligations evidenced by the Notes.

(G)          Each provision of this Indenture that in any way relates to the Trustee (including any provision that affects the liability of, or affords protection to, the Trustee) is subject to this Section 10.01, regardless of whether such provision so expressly provides.

(H)          In the event that the Trustee is also acting as Note Agent hereunder, the rights and protections afforded to the Trustee pursuant to this Article 10 shall also be afforded to such Note Agent.

**Section 10.02.**Rightsof the Trustee.

The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel. The Trustee may consult with counsel; and the advice of such counsel, or any Opinion of Counsel, will constitute full and complete authorization of the Trustee to take or omit to take any action in good faith in reliance thereon without liability.

- 76 -

(C)          The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any such agent appointed with due care.

(G)          The Trustee will not be responsible or liable for any punitive, special, indirect or consequential loss or damage (including lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(H)          The permissive rights of the Trustee set forth in this Indenture will not be construed as duties imposed on the Trustee.

(I)           The Trustee will not be required to give any bond or surety in respect of the execution or performance of this Indenture or otherwise.

(J)            Unless a Responsible Officer of the Trustee has received notice from the Company that Special Interest or Additional Interest is owing or accruing, on the Notes, the Trustee may assume that no Special Interest or Additional Interest, as applicable, is payable or accruing.

(K)          The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and will be enforceable by, the Trustee in each of its capacities under this Indenture, including as Note Agent.

(L)           The Trustee will not be charged with knowledge of any document or agreement other than this Indenture and the Notes.

(M)          Neither the Trustee nor any Note Agent will have any responsibility or liability to any person for any action taken or not taken by, or any records or any other aspect of the operations of, the Depositary (including the delivery of notices, or the making of payments, through the facilities of the Depositary) and may conclusively rely, without investigation, on any information provided by the Depositary.

**Section 10.03.**IndividualRights of the Trustee.

The Trustee, in its individual or any other capacity, may become the owner or pledgee of any Note and may otherwise deal with the Company or any of its Affiliates with the same rights that it would have if it were not Trustee; provided, however, that if the Trustee acquires a “conflicting interest” (within the meaning of Section 310(b) of the Trust Indenture Act), then it must eliminate such conflict within ninety (90) days or resign as Trustee. Each Note Agent will have the same rights and duties as the Trustee under this Section 10.03.

- 77 -

**Section 10.04.**Trustee’sDisclaimer.

The Trustee will not be (A) responsible for, and makes no representation as to, the validity or adequacy of this Indenture or the Notes; (B) accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture; (C) responsible for the use or application of any money received by any Paying Agent other than the Trustee; and (D) responsible for any statement or recital in this Indenture, the Notes or any other document relating to the sale of the Notes or this Indenture, other than the Trustee’s certificate of authentication.

**Section 10.05.**Noticeof Defaults.

If a Default occurs and is continuing and is actually known to a Responsible Officer of the Trustee, then the Trustee will send Holders a notice of such Default within ninety (90) days after it occurs or, if it is not actually known to a Responsible Officer of the Trustee at such time, promptly (and in any event within ten (10) Business Days) after it becomes actually known to a Responsible Officer of the Trustee; provided, however, that, except in the case of a Default in the payment of the principal of, or interest, if any, on, any Note, the Trustee may withhold such notice if and for so long as it in good faith determines that withholding such notice is in the interests of the Holders. For the avoidance of doubt, the Trustee will not be required to deliver such notice at any time after such Default is cured or waived. The Trustee will not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless (A) written notice thereof has been received by a Responsible Officer; and (B) such notice references the Notes and this Indenture and states on its face that a Default or Event of Default, as applicable, has occurred.

**Section 10.06.**Compensationand Indemnity.

(A)          The Company will, from time to time, pay the Trustee reasonable compensation for its acceptance of this Indenture and services under this Indenture as separately agreed to by the Company and the Trustee. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. In addition to the compensation for the Trustee’s services, the Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it under this Indenture, including the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

(B)          The Company will indemnify and hold harmless the Trustee (in each of its capacities under this Indenture, including as Note Agent) and its directors, officers, employees and agents, in their capacities as such, against any and all losses, liabilities or expenses (including taxes (other than taxes based upon, or measured by or determined by the income of the Trustee) and reasonable attorneys’ fees and expenses and court costs) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 10.06) and defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties under this Indenture, except to the extent any such loss, liability or expense is attributable (as determined by a final decision of a court of competent jurisdiction) to its gross negligence or willful misconduct. The Trustee will promptly notify the Company of any claim for which it may seek indemnity, but the Trustee’s failure to so notify the Company will not relieve the Company of its obligations under this Section 10.06(B). The Company will defend such claim, and the Trustee will cooperate in such defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement of any such claim made without its consent, which consent will not be unreasonably withheld.

- 78 -

(C)          The obligations of the Company under this Section 10.06 will survive the resignation or removal of the Trustee and the discharge of this Indenture.

If to the Company:

ProPetro Holding Corp.

One Marienfeld Place, 110 N. Marienfeld Street, Suite 300

Midland, Texas 79701

Attention: General Counsel

- 80 -

If to the Trustee:

U.S. Bank Trust Company, National Association

2 Concourse Parkway NE, Suite 800

Atlanta, GA 30328

Attention: Global Corporate Trust Services

Notwithstanding anything to the contrary in the preceding paragraph, notices to the Trustee (other than a notice pursuant to Section 2.12) or any Note Agent must be in writing and will be deemed to have been given upon actual receipt by the Trustee or such Note Agent, as applicable.

The Company or the Trustee, by notice to the other, may designate additional or different addresses (including facsimile numbers and electronic addresses) for subsequent notices or communications.

The Trustee will not have any duty to confirm that the person sending any notice, instruction or other communication by electronic transmission (including by e-mail, facsimile transmission, web portal or other electronic methods) is, in fact, a person authorized to do so. Electronic signatures believed by the Trustee to comply with the ESIGN Act of 2000 or other applicable law (including electronic images of handwritten signatures and digital signatures provided by DocuSign, Orbit, Adobe Sign or any other digital signature provider acceptable to the Trustee) will be deemed original signatures for all purposes. Any person that uses electronic signatures or electronic methods to send communications to the Trustee assumes all risks arising out of such use, including the risk of the Trustee acting on an unauthorized communication and the risk of interception or misuse by third parties. Notwithstanding anything to the contrary in this paragraph, the Trustee may, in any instance and in its sole discretion, require that an original document bearing a manual signature be delivered to the Trustee in lieu of, or in addition to, any such electronic communication.

All notices and communications (other than those sent to Holders) will be deemed to have been duly given: (A) at the time delivered by hand, if personally delivered; (B) five (5) Business Days after being deposited in the mail, postage prepaid, if mailed; (C) when receipt is acknowledged, if transmitted by facsimile, electronic transmission or other similar means of unsecured electronic communication; and (D) the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery.

All notices or communications required to be made to a Holder pursuant to this Indenture must be made in writing and will be deemed to be duly sent or given in writing if mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery, to its address shown on the Register; provided, however, that a notice or communication to a Holder of a Global Note may, but need not, instead be sent pursuant to the Depositary Procedures (in which case, such notice will be deemed to be duly sent or given in writing). The failure to send a notice or communication to a Holder, or any defect in such notice or communication, will not affect its sufficiency with respect to any other Holder.

- 81 -

If the Trustee is then acting as the Depositary’s custodian for the Notes, then, at the reasonable request of the Company to the Trustee, the Trustee will cause any notice prepared by the Company to be sent to any Holder(s) pursuant to the Depositary Procedures, provided such request is evidenced in a Company Order delivered, together with the text of such notice, to the Trustee at least two (2) Business Days before the date such notice is to be so sent. For the avoidance of doubt, such Company Order need not be accompanied by an Officer’s Certificate or Opinion of Counsel. The Trustee will not have any liability relating to the contents of any notice that it sends to any Holder pursuant to any such Company Order.

If a notice or communication is mailed or sent in the manner provided above within the time prescribed, it will be deemed to have been duly given, whether or not the addressee receives it.

Notwithstanding anything to the contrary in this Indenture or the Notes, (A) whenever any provision of this Indenture requires a party to send notice to another party, no such notice need be sent if the sending party and the recipient are the same Person acting in different capacities (and, for purposes of the interpretation of this Indenture, such notice will be deemed to have been duly sent at the time otherwise required by this Indenture); and (B) whenever any provision of this Indenture requires a party to send notice to more than one receiving party, and each receiving party is the same Person acting in different capacities, then only one such notice need be sent to such Person.

(B)          an Opinion of Counsel that complies with Section 11.03 and states that, in the opinion of such counsel, all such conditions precedent and covenants, if any, have been satisfied.

(A)          a statement that the signatory thereto has read such covenant or condition;

Delivery of such opinion to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation of Dealer under Section 2(a)(i) of the Agreement.

(b)

Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than [__]^47^ million (in the case of the first such notice) or (ii) thereafter more than [__]^48^ million less than the number of Shares included in the immediately preceding Repurchase Notice; provided that, with respect to any repurchase of Shares pursuant to a plan under Rule 10b5-1 under the Exchange Act (as defined below), Counterparty may elect to satisfy such requirement by giving Dealer written notice of entry into such plan on the date of such entry, the maximum number of Shares that may be purchased thereunder and the approximate dates or periods during which such repurchases may occur (with such maximum number of Shares deemed repurchased on the date of such notice for purposes of this Section 9(b)), in each case so long as such written notice shall not contain any material non-public information with respect to the Issuer or the Shares. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’s commercially reasonable hedging activities as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from commercially reasonable hedging activities or cessation of commercially reasonable hedging activities and any losses in connection therewith with respect to the Transaction), claims, damages, judgments, liabilities and reasonable expenses (including reasonable out-of-pocket attorney’s fees of one outside counsel in each relevant jurisdiction), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable out-of-pocket legal or other expenses incurred in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person (such consent not to be unreasonably withheld, conditioned or delayed), effect any settlement of any pending or threatened proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or would have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph ‎(b) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction.

(ii)

Dealer may transfer or assign all or any part of its rights or obligations under the Transaction (A) without Counterparty’s consent (but with prompt subsequent (but in no event more than two Exchange Business Days’) written notice to Counterparty), to any affiliate or branch of Dealer (1) that has a long-term issuer rating or a rating for its long term, unsecured and unsubordinated indebtedness that is equal to or better than the lesser of (a) Dealer’s long-term issuer rating or the rating for Dealer’s long-term, unsecured and unsubordinated indebtedness at the time of such transfer or assignment and (b) A- by S&P Global Ratings, a division of S&P Global Inc., or its successor (“S&P”), or A3 by Moody’s Investors Service, Inc. or its successor (“Moody’s”) or, if either S&P or Moody’s ceases to rate such issuer or such indebtedness, as the case may be, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer, or (2) whose obligations hereunder will be guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions, by Dealer (or its ultimate parent), or (B) with Counterparty’s consent (such consent not to be unreasonably withheld or delayed), to any other third party with a long-term issuer rating or a rating for its long term, unsecured and unsubordinated indebtedness equal to or better than the lesser of (1) Dealer’s long-term issuer rating or the rating for Dealer’s long-term, unsecured and unsubordinated indebtedness at the time of such transfer or assignment and (2) A- by S&P or A3 by Moody’s or, if either S&P or Moody’s ceases to rate such issuer or such indebtedness, as the case may be, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that (x) Dealer and such affiliate, branch or third party, as the case may be, both qualify as “dealers in securities” within the meaning of Section 475(c)(1) of the Code or such transfer or assignment does not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code, (y) Counterparty will not, as a result of any transfer or assignment (including, for the avoidance of doubt, after giving effect to any indemnity or other contractual obligation from the transferee or assignee to Counterparty provided in connection with such transfer or assignment), be required to (I) pay the transferee or assignee on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than the amount, if any, that Counterparty would have been required to pay to Dealer in the absence of such transfer or assignment (for the avoidance of doubt, except to the extent that the greater amount is due to a Change in Tax Law after the date of such transfer or assignment pursuant to Section 2(d)(i)(4)(B) of the Agreement) or (II) receive from the transferee or assignee on any payment date an amount, after taking into account amounts payable or deliverable under Section 2(d)(i)(4) of the Agreement as well as any applicable withholding or deduction from such amounts payable, that would be less than the amount or a number of Shares, if any, that Counterparty would have received from Dealer in the absence of such transfer or assignment (for the avoidance of doubt, except to the extent that the lesser amount or number of Shares is due to a Change in Tax Law after the date of such transfer or assignment pursuant to Section 2(d)(i)(4)(B) of the Agreement), and (z) Dealer shall cause the transferee or assignee to make such Payee Tax Representations and to provide such tax documentation (including a duly executed and completed U.S. Internal Revenue Service Form W-9 or applicable Form W-8 (or applicable successor form)) as may be reasonably requested by Counterparty to permit Counterparty to determine that the result described in clauses (x) and (y) will not occur upon or after such transfer or assignment. Dealer shall notify Counterparty of any transfer or assignment pursuant to the foregoing sentence promptly following such transfer or assignment. If at any time at which (A) the Section 16 Percentage exceeds 8.5%, (B) the Option Equity Percentage exceeds 14.5% or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”), such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance of doubt, the provisions of Section ‎9(k) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence as if Counterparty was not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the number of Shares that Dealer and each person subject to aggregation of Shares with Dealer and each “group” of which Dealer is a member or may be deemed a member, in each case, under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder, directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding. The “Option Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of (1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The “Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation, regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares (“ApplicableRestrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable discretion. The “ApplicableShare Limit” means a number of Shares equal to (A) the minimum number of Shares that could give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction, as determined by Dealer in its reasonable discretion, but excluding reporting obligations arising under Section 13 of the Exchange Act as in effect on the Trade Date, minus (B) 1% of the number of Shares outstanding.

(iii)

Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities, or make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any such performance.

(f)	Staggered Settlement. If upon advice of counsel with respect to applicable legal and regulatory<br>requirements, including any requirements relating to Dealer’s hedging activities hereunder, Dealer reasonably determines that it<br>would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares to be delivered by Dealer<br>on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any Settlement Date (a “NominalSettlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered Settlement Date”)<br>as follows:
(i)	in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (the first<br>of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business Day following<br>such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date;
---	---
(ii)	the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered<br>Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date; and
---	---
(iii)	the Settlement Method terms will apply on each Staggered Settlement Date, except that the cash and/or<br>Shares due upon settlement will be allocated among such Staggered Settlement Dates as specified by Dealer in the notice referred to in<br>clause (i) above.
---	---
(g)	[Role of Agent. [Insert relevant Dealer agency or communications language, if any.]<br>Any performance by Counterparty of its obligations (including notice obligations) through or by means of [DEALER AGENT’s] agency<br>for Dealer shall constitute good performance of Counterparty’s obligations to Dealer.][Reserved.]
---	---
(h)	Additional Termination Events.
---	---
(i)	Notwithstanding anything to the contrary in this Confirmation, upon any Early Conversion in respect of<br>which a “Notice of Conversion” (as such term is defined in the Indenture) that is effective as to Counterparty has been delivered<br>by the relevant converting “Holder” (as such term is defined in the Indenture):
---	---
(A)	Counterparty shall, within ten Scheduled Trading Days of the “Conversion Date” (as such term<br>is defined in the Indenture) for such Early Conversion, provide written notice (an “Early Conversion Notice”) to Dealer<br>specifying the number of Convertible Notes surrendered for conversion on such “Conversion Date” (such Convertible Notes, the<br>“Affected Convertible Notes”), and the giving of such Early Conversion Notice shall constitute an Additional Termination<br>Event as provided in this clause ‎(i)[; provided that any “Early Conversion Notice” as defined in, and delivered<br>to Dealer pursuant to, the Base Call Option Confirmation shall be deemed to be an Early Conversion Notice pursuant to this Confirmation<br>and the terms of such “Early Conversion Notice” shall apply, mutatis mutandis, to this Confirmation]^49^;
---	---

^49^ Include in Additional Call Option Confirmation only.

Page 24

(B)

upon receipt of any such Early Conversion Notice, Dealer shall designate an Exchange Business Day as an Early Termination Date (which Exchange Business Day shall be no earlier than one Scheduled Valid Day following the “Conversion Date” (as such term is defined in the Indenture) for such Early Conversion) with respect to the portion of the Transaction corresponding to a number of Options (the “Affected Number of Options”) equal to the lesser of (x) the number of Affected Convertible Notes [minus the “Affected Number of Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Affected Convertible Notes (and for the purposes of determining whether any Options under this Confirmation or under, and as defined in, the Base Call Option Confirmation will be among the Affected Number of Options hereunder or under, and as defined in, the Base Call Option Confirmation, such Affected Convertible Notes shall be allocated first to the Base Call Option Confirmation until all Options thereunder are exercised or terminated)]^50^ and (y) the Number of Options as of the “Conversion Date” (as such term is defined in the Indenture) for such Early Conversion;

(C)

any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the Affected Number of Options, (y) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (z) the terminated portion of the Transaction were the sole Affected Transaction; provided that the amount payable with respect to such termination shall not be greater than (1) the Applicable Percentage, multiplied by (2) the Affected Number of Options, multiplied by (3) (x) the sum of (i) the amount of cash paid (if any) to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note (including any cash payable pursuant to Section [5.07]^51^ of the Indenture) and (ii) the number of Shares delivered (if any) to the “Holder” (as such term is defined in the Indenture) of an Affected Convertible Note upon conversion of such Affected Convertible Note (including any Shares deliverable pursuant to Section [5.07]^52^ of the Indenture), multiplied by the Applicable Limit Price on the date of delivery of such number of Shares upon settlement of the conversion of the relevant Affected Convertible Note (the “Conversion Settlement Date”), minus (y) the Synthetic Instrument Adjusted Issue Price per Affected Convertible Note, as determined by the Calculation Agent in good faith and in a commercially reasonable manner. “Synthetic Instrument Adjusted Issue Price” shall mean the amount determined by the Calculation Agent by reference to the table set forth below (the “Synthetic Instrument AIP Table”) based on the Conversion Settlement Date (the “Unwind Date”). If the relevant Unwind Date is not listed below, the amount in the preceding sentence shall be determined by the Calculation Agent by reference to the table below using a linear interpolation between the lower and higher Synthetic Instrument Adjusted Issue Prices for the Unwind Dates immediately preceding and immediately following the relevant Unwind Date. For the avoidance of doubt, any payment pursuant to this paragraph shall be subject to Section 9(k) of this Confirmation.

Within ten Scheduled Trading Days following any Repayment Event (as defined below), Counterparty (x) in the case of a Repayment Event resulting from the repurchase of any Convertible Notes by Counterparty (1) upon the occurrence of a “Fundamental Change” (as defined in the Indenture), or (2) in connection with an “Optional Redemption” (as defined in the Indenture), shall notify Dealer in writing of such Repayment Event and (y) in the case of a Repayment Event not described in clause (x) above, may notify Dealer of such Repayment Event, in each case, including the aggregate principal amount of Convertible Notes subject to such Repayment Event (any such notice, a “Repayment Notice”); provided that no such Repayment Notice described in clause (x)(2) or (y) above shall be effective unless it contains the representation by Counterparty set forth in Section 8(f) as of the date of such Repayment Notice[; provided further that any “Repayment Notice” as defined in, and delivered to Dealer pursuant to, the Base Call Option Confirmation shall be deemed to be a Repayment Notice pursuant to this Confirmation and the terms of such “Repayment Notice” shall apply, mutatis mutandis, to this Confirmation]^54^. The receipt by Dealer from Counterparty of any Repayment Notice shall constitute an Additional Termination Event as provided in this Section ‎9(h)(ii). Upon receipt of any such Repayment Notice, Dealer shall designate an Exchange Business Day following receipt of such Repayment Notice as an Early Termination Date with respect to the portion of the Transaction corresponding to a number of Options (the “RepaymentOptions”) equal to the lesser of (A) [(x)]^55^ the aggregate principal amount of such Convertible Notes specified in such Repayment Notice, divided by USD 1,000, [minus (y) the number of “Repayment Options” (as defined in the Base Call Option Confirmation), if any, that relate to such Convertible Notes (and for the purposes of determining whether any Options under this Confirmation or under, and as defined in, the Base Call Option Confirmation will be among the Repayment Options hereunder or under, and as defined in, the Base Call Option Confirmation, the Convertible Notes specified in such Repayment Notice shall be allocated first to the Base Call Option Confirmation until all Options thereunder are exercised or terminated)]^56^ and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Repayment Options. Any payment hereunder with respect to such termination (the “Repayment UnwindPayment”) shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to the number of Repayment Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction; provided that, in the event of a Repayment Event resulting from a “Fundamental Change” (as defined in the Indenture) or in connection with an “Optional Redemption” (as defined in the Indenture), the Repayment Unwind Payment shall not be greater than (x) the number of Repayment Options multiplied by (y) the product of (A) the Applicable Percentage and (B) the excess of (I) the amount paid by Counterparty per Convertible Note in connection with such Repayment Event pursuant to the relevant sections of the Indenture over (II) the Synthetic Instrument Adjusted Issue Price per Convertible Note determined by the Calculation Agent by reference to the Synthetic Instrument AIP Table based on the date of the Repayment Event (the “Repayment Unwind Date”) as if such Repayment Unwind Date were the Unwind Date. If the Repayment Unwind Date is not listed in the Synthetic Instrument AIP Table, the amount in clause (II) of the preceding sentence shall be determined by the Calculation Agent by reference to the Synthetic Instrument AIP Table, using a linear interpolation between the lower and higher Synthetic Instrument Adjusted Issue Prices per Convertible Note for the dates immediately preceding and immediately following the Repayment Unwind Date. For the avoidance of doubt, any payment pursuant to this paragraph shall be subject to Section 9(k) of this Confirmation. “Repayment Event” means that (i) any Convertible Notes are repurchased (whether in connection with or as a result of a fundamental change, howsoever defined, or for any other reason) or redeemed by Counterparty or any of its subsidiaries, (ii) any Convertible Notes are delivered to Counterparty or any of its subsidiaries in exchange for delivery of any property or assets of such party (howsoever described), (iii) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the Convertible Notes (for any reason other than as a result of an acceleration of the Convertible Notes that results in an Additional Termination Event pursuant to the following Section 9(h)(iii)), or (iv) any Convertible Notes are exchanged by or for the benefit of the “Holders” (as defined in the Indenture) thereof for any other securities of Counterparty or any of its subsidiaries (or any other property, or any combination thereof) pursuant to any exchange offer or similar transaction. For the avoidance of doubt, any conversion of Convertible Notes (whether into cash, Shares, “Reference Property” (as defined in the Indenture) or any combination thereof) pursuant to the terms of the Indenture shall not constitute a Repayment Event.

(iii)

Notwithstanding anything to the contrary in this Confirmation, if an event of default with respect to Counterparty occurs under the terms of the Convertible Notes as set forth in Section [7.01]^57^ of the Indenture and such event of default results in the Convertible Notes becoming or being declared due and payable pursuant to the terms of the Indenture, then such event of default shall constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event, (A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and (C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.
