      the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of interest on or principal of the U.S. Government Obligation evidenced by such
      depository receipt.

    ARTICLE II

    

    

    THE NOTES

    

    

    SECTION 2.1.          Form, Dating and Terms.

    

    

    (a)          The aggregate principal amount of Notes that may be
        authenticated and delivered under this Indenture is unlimited.  The Initial Notes issued on the date hereof shall be in an aggregate principal amount of $500,000,000.  In addition, the Issuer may issue Additional Notes from time to time in
        accordance with the provisions of this Indenture.  Furthermore, Notes may be authenticated and delivered upon registration of transfer, exchange or in lieu of, other Notes pursuant to Sections 2.2,
        2.6, 2.7, 2.9,
        5.5 or 9.4 or in connection with a Change of Control Repurchase Event pursuant to Section 3.5.

    

    

    With respect to any Additional Notes, the Issuer shall set forth in (1) a Board Resolution and (2)(i) an Officers’ Certificate and/or (ii) one or more
      indentures supplemental hereto, as applicable, the following information:

    

    

    (A)          the aggregate principal amount of
        such Additional Notes to be authenticated and delivered pursuant to this Indenture;

    

    

    (B)          the issue price and the issue date of
        such Additional Notes, including the date from which interest shall accrue; and

    

    

    (C)          whether such Additional Notes shall
        be Restricted Notes.

    

    

    In authenticating and delivering Additional Notes, the Trustee shall be entitled to receive and shall be fully protected in relying upon, in addition to
      the Opinion of Counsel and Officers’ Certificate required by Section 12.2, an Opinion of Counsel as to the due authorization, execution, delivery, validity and
      enforceability of such Additional Notes.

    

    

    The Initial Notes and the Additional Notes shall be considered collectively as a single class for all purposes of this Indenture; provided that Additional Notes will not be issued with the same CUSIP or ISIN, as applicable, as existing Notes unless such Additional Notes are fungible with such
      existing Notes for U.S. federal income tax purposes and otherwise.  Holders of the Initial Notes and the Additional Notes shall vote and consent together as one class on all matters to which such Holders are entitled to vote or consent, and none of
      the Holders of the Initial Notes or the Additional Notes shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

    

    

    If any of the terms of any Additional Notes are established by action taken pursuant to a Board Resolution of the Issuer, a copy of an appropriate record
      of such action shall be certified by the Secretary or any Assistant

    

    

    
      7

      
        


    

    

    

    Secretary of the Issuer and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate and/or an indenture supplemental hereto, as applicable,
      setting forth the terms of the Additional Notes.

    

    

    (b)          The Initial Notes are being offered and sold (A) to
        persons reasonably believed to be QIBs in reliance on Rule 144A or (B) in offshore transactions in reliance on Regulation S. Any Additional Notes (if issued as Restricted Notes) (the “Additional








            Restricted Notes”) will be offered and issued, or resold, as the case may be, initially only (A) to persons reasonably believed to be QIBs in reliance on Rule 144A and (B) in offshore transactions in reliance on Regulation S.  Such
        Initial Notes and Additional Restricted Notes may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S, in each case, in accordance with the procedure described herein.  Additional Notes offered after the date
        hereof may be offered and  issued, or offered and sold, as the case may be, by the Issuer from time to time pursuant to one or more purchase, underwriting or other agreements, as the case may be, in accordance with applicable law.

     

      

    Initial Notes and any Additional Restricted Notes offered and sold to QIBs in the United States of America in reliance on Rule 144A (the “Rule 144A Notes”), shall be issued in the form of a permanent global Note substantially in the form of Exhibit A,
      which is hereby incorporated by reference and made a part of this Indenture, including appropriate legends as set forth in Section 2.1(d) and (e) (the “Rule 144A Global Note”), deposited with the Trustee, as custodian for DTC, duly executed by the Issuer and
      authenticated by the Trustee as hereinafter provided.  The Rule 144A Global Note may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate.  The
      aggregate principal amount of the Rule 144A Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as hereinafter provided.

    

    

    Initial Notes and any Additional Restricted Notes offered and issued, or offered and sold, as the case may be, outside the United States of America (the
      “Regulation S Notes”) in reliance on Regulation S shall be issued in the form of a permanent global Note substantially in the form of Exhibit A including appropriate legends as set forth in Section 2.1(d) and (e) (the “Regulation S Global Note” and, together with the Rule 144A Global Note, the “Global Notes”).  Each Regulation S Global Note shall be deposited upon issuance with, or on behalf of, the Trustee as custodian for DTC in the manner described in this Article II for credit to the respective accounts of the purchasers (or to such other accounts as they may direct), including, but not limited to, accounts at Euroclear Bank S.A./N.V. (“Euroclear”) or Clearstream Banking, société anonyme (“Clearstream”). Through and including the 40th day after the Issue Date
      (such period through and including such 40th day, the “Restricted Period”), beneficial interests in the Regulation S Global Note may be held only through Euroclear and
      Clearstream (in each case, as indirect participants in DTC), unless transferred to a person that takes delivery through a Rule 144A Global Note in accordance with the transfer and certification requirements described herein.

    

    

    The Regulation S Global Note may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be
      represented by a single certificate.  The aggregate principal amount of the Regulation S Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for DTC or its nominee, as
      hereinafter provided.

    

    

    The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of the Paying Agent designated by the Issuer
      and maintained for such purpose (which shall initially be the office of the Trustee maintained for such purpose), or at such other office or agency of the Issuer as may be maintained for such purpose pursuant to Section 2.3; provided,
        however, that, at the option of the Paying Agent, each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Notes Register or (ii) wire transfer to an
      account located in the United States maintained by the payee, subject to the last sentence of this paragraph.  Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and interest) will be made by wire
      transfer of immediately available funds to the accounts specified by DTC.  Payments in respect of Notes represented by Definitive Notes (including principal, premium, if any, and interest) held by a Holder of at least $1,000,000 aggregate principal
      amount of Notes represented by Definitive Notes will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or
      the Paying Agent to such effect designating such account no later than fifteen (15) days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

    The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage, in addition to those set forth on Exhibit A and in Section 2.1(d) and (e). 








      The Issuer shall approve any notation, endorsement or legend on the Notes.  Each Note shall be dated the date of its authentication.  The terms of the Notes set forth in Exhibit A
      are part of the terms of this Indenture and, to the extent applicable, the Issuer, the Guarantors and the Trustee expressly agree to be bound by such terms.

    

    

    (c)          Denominations.  The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

    

    

    (d)          Restrictive Legends.  Unless and until (i) an Initial Note or an Additional Note issued as a Restricted Note is sold under an effective registration statement, or (ii) the Trustee receives an Opinion of Counsel reasonably
        satisfactory to it stating that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act, the following legends shall apply:

    

    

    (1)          Restricted Note Legend. Each Note certificate evidencing the Global Notes (and all Notes issued in exchange therefor or in substitution thereof) shall bear the following
        legend on the face thereof:

    

    

    THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE
      SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH BELOW. EACH PURCHASER OF THIS NOTE IS HEREBY NOTIFIED
      THAT THE SELLER OF THIS NOTE MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A, REGULATION S OR ANOTHER EXEMPTION THEREUNDER.

    

    

    BY ITS ACCEPTANCE HEREOF, THE HOLDER OF THIS NOTE (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS
      DEFINED IN RULE 144A UNDER THE SECURITIES ACT), (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT OR (C) IT IS AN “INSTITUTIONAL” ACCREDITED INVESTOR (AS DEFINED
      IN RULE 501(a)(1), (2), (3) OR (7) UNDER REGULATION D PROMULGATED UNDER THE SECURITIES ACT (AN “ACCREDITED INVESTOR”) AND (2) AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED NOTES, THAT IT WILL NOT WITHIN
      [ONE YEAR— FOR NOTES ISSUED PURSUANT TO RULE 144A][40 DAYS—FOR NOTES ISSUED IN OFFSHORE TRANSACTIONS PURSUANT TO REGULATION S] AFTER THE LATER OF THE DATE OF THE ORIGINAL ISSUANCE OF THIS NOTE AND THE DATE ON WHICH THE ISSUER OR ANY OF ITS AFFILIATES
      OWNED THIS NOTE, OFFER, RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (X) (I) TO THE ISSUER OR ANY SUBSIDIARY THEREOF, (II) FOR SO LONG AS THIS NOTE IS ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT INSIDE THE UNITED STATES TO A
      PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (III) INSIDE THE UNITED STATES TO AN ACCREDITED INVESTOR THAT IS ACQUIRING THE NOTES FOR ITS OWN ACCOUNT OR FOR THE
      ACCOUNT OF SUCH AN ACCREDITED INVESTOR, IN EACH CASE IN A MINIMUM PRINCIPAL AMOUNT OF THE NOTES OF $250,000, FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TO OR FOR THE OFFER OR SALE IN CONNECTION WITH ANY DISTRIBUTION IN VIOLATION OF THE SECURITIES
      ACT, AND THAT PRIOR TO SUCH TRANSFER, FURNISHES (OR HAS FURNISHED ON ITS BEHALF BY A U.S. BROKER DEALER) TO THE TRUSTEE A SIGNED LETTER

    
      9

      
        


    

    

    

    CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS NOTE (THE FORM OF
      WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE FOR THIS NOTE), (IV) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT (IF AVAILABLE), (V) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED
      BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE), (VI) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF THE ISSUER SO REQUESTS) OR (VII) PURSUANT TO AN EFFECTIVE
      REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (Y) IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES AND OTHER JURISDICTIONS. BY ITS ACCEPTANCE HEREOF, THE HOLDER OF THIS NOTE FURTHER AGREES THAT IT WILL GIVE
      TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND IN CONNECTION WITH ANY TRANSFER OF THIS NOTE PURSUANT TO SUBCLAUSES (III) TO (VI) OF CLAUSE (X) ABOVE, AND THAT, THE HOLDER MUST, PRIOR TO SUCH
      TRANSFER, FURNISH TO THE TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT
      SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

    

    

    (2)          The








        Regulation S Global Note shall bear the following legend on the face thereof:

    

    

    BY ITS ACQUISITION HEREOF, THE HOLDER HEREOF
        REPRESENTS THAT IT IS NOT A U.S. PERSON NOR IS IT PURCHASING FOR THE ACCOUNT OF A U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

    

    

    (e)          Global Note Legend.  Each Global Note, whether or not an Initial Note, shall bear the following legend on the face thereof:

    

    

    UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO.
      OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
      VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

    

    

    TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO DTC, TO NOMINEES OF DTC OR TO A SUCCESSOR
      THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE

    
      10

      
        


    

    

    

    RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

    

    

    (f)          Book‐Entry Provisions.  (i)  This Section 2.1(f) shall apply only to Global Notes deposited with the Trustee, as custodian for DTC.

    

    

    (1)          Each Global Note
        initially shall (x) be registered in the name of DTC or the nominee of DTC, (y) be delivered to the Notes Custodian for DTC and (z) bear the applicable legends as set forth in Section 2.1(e). 








        Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to DTC, its successors or its respective nominees, except as set forth in Section 2.1(f)(4) and (g).  If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another
        Global Note, the Notes Custodian will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount
        of the other Global Note.  Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or
        exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial
        interests in such other Global Note for as long as it remains such an interest.

    

    

    (2)          Members of, or
        participants in, DTC (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by DTC or by the Notes Custodian as
        the custodian of DTC or under such Global Note, and DTC may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner of such Global Note for all purposes whatsoever.  Notwithstanding the foregoing,
        nothing herein shall prevent the Issuer or the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the
        operation of customary practices of DTC governing the exercise of the rights of a holder of a beneficial interest in any Global Note.

    

    

    (3)          In connection with
        any transfer of a portion of the beneficial interest in a Global Note pursuant to Section 2.1(g) to beneficial owners who are required to hold Definitive Notes, the Notes
        Custodian shall reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Issuer shall
        execute, and the Trustee shall authenticate and make available for delivery, one or more Definitive Notes of like tenor and amount.

    

    

    (4)          In connection with
        the transfer of an entire Global Note to beneficial owners pursuant to Section 2.1(g), such Global Note shall be deemed to be surrendered to the Trustee for cancellation,
        and the Issuer shall execute, and the Trustee shall authenticate and make available for delivery, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of
        Definitive Notes of authorized denominations.

    

    

    (5)          The registered Holder
        of a Global Note may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

    

    

    (6)          Any Holder of a
        Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Note may be effected only through a book‐entry system maintained by (i) the Holder of such Global Note (or its agent) or (ii) any
        holder of a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry.

    

    

    (g)          Definitive Notes.  Except as provided below, owners of beneficial interests in Global Notes will not be entitled to receive Definitive Notes.  Definitive Notes shall be transferred to all beneficial owners in exchange for
        their beneficial interests in a Global Note if (A) DTC notifies the Issuer that it is unwilling or unable to continue as Depositary for the Global Note, or DTC has ceased to be a clearing agency registered under the Exchange Act, and, in each case,
        the Issuer fails to appoint a successor depositary within 90 days or (B) there shall have occurred

    
      11

      
        


    

    

    

    and be continuing a Default with respect to the Notes under this Indenture.  In the event of the occurrence of any of the events specified in clause (A) or (B) of the
      preceding sentence, the Issuer shall promptly comply with the provisions hereof to issue Definitive Notes.  In addition, any Note transferred to an affiliate (as defined in Rule 405 under the Securities Act) of the Issuer or evidencing a Note that
      has been acquired by an affiliate in a transaction or series of transactions not involving any public offering must, until six months (or one year if the holding period under Rule 144 then applicable to such Note is one year) after the last date on
      which either the Issuer or any affiliate of the Issuer was an owner of the Note, be in the form of a Definitive Note and bear the legend regarding transfer restrictions in Section 2.1(d).

    

    

    (1)          Any Definitive Note
        delivered in exchange for an interest in a Global Note pursuant to Section 2.1(f) shall, except as otherwise provided by Section 2.6(d), bear the applicable legend regarding transfer restrictions applicable to the Global Note set forth in Section 2.1(d).

    

    

    (2)          If a Definitive Note
        is transferred or exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such Definitive Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or exchange
        and (z) in the event that such transfer or exchange involves less than the entire principal amount of the canceled Definitive Note, the Issuer shall execute, and the Trustee shall authenticate and make available for delivery to the transferring
        Holder a new Definitive Note representing the principal amount not so transferred.

    

    

    (3)          If a Definitive Note
        is transferred or exchanged for another Definitive Note, (x) the Trustee will cancel the Definitive Note being transferred or exchanged, (y) the Issuer shall execute, and the Trustee shall authenticate and make available for delivery, one or more
        new Definitive Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Definitive Note (in the
        case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Definitive Note, the Issuer shall execute, and the Trustee
        shall authenticate and make available for delivery to the Holder thereof, one or more Definitive Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Definitive
        Notes, registered in the name of the Holder thereof.

    

    

    SECTION 2.2.          Execution and Authentication.  One Officer shall sign the Notes for the Issuer by manual, facsimile or other electronic signature.  If the Officer whose signature is on a Note no longer holds that
        office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless.

    

    

    A Note shall not be valid until an authorized officer of the Trustee manually authenticates the Note.  The signature of the Trustee on a Note shall be
      conclusive evidence that such Note has been duly and validly authenticated and issued under this Indenture.  A Note shall be dated the date of its authentication.

    

    

    At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate: (1) Initial Notes for original
      issue on the Issue Date in an aggregate principal amount of $500,000,000 and (2) subject to the terms of this Indenture, Additional Notes for original issue in an unlimited principal amount, in each case upon a written order of the Issuer signed by
      one Officer (the “Issuer Order”).  Such Issuer Order shall specify whether the Notes will be in the form of Definitive Notes or Global Notes, the amount of the Notes to be
      authenticated, the date on which the original issue of Notes is to be authenticated, the holder of the Notes and whether the Notes are to be Initial Notes or Additional Notes. For the avoidance of doubt, no Opinion of Counsel shall be required in
      connection with the authentication of the Initial Notes.

    

    

    The Trustee may appoint an agent (the “Authenticating Agent”) reasonably
      acceptable to the Issuer to authenticate the Notes.  Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer.  Unless limited by the terms of such appointment, any such
      Authenticating Agent may authenticate Notes whenever the Trustee may do so.  Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent.  An Authenticating Agent has the same rights as any
      Registrar, Paying Agent or agent for service of notices and demands.

    

    

    
      12

      
        


    

    

    

    In case the Issuer, pursuant to Article IV, shall be consolidated or merged
      with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into
      which the Issuer shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to Article IV, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may (but shall not be required),
      from time to time, at the request of the successor Person, be exchanged for other Notes executed in the name of the successor Person with such changes in phraseology and form as may be appropriate to reflect such successor Person, but otherwise in
      substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon the Issuer Order of the successor Person, shall authenticate and make available for delivery Notes as specified in such order for
      the purpose of such exchange.  If Notes shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section 2.2 in exchange or
      substitution for or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time outstanding for Notes authenticated and delivered
      in such new name.

    

    

    SECTION 2.3.          Registrar and Paying Agent.  The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Notes may be presented for payment.  The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Notes Register”).  The Issuer may have one or more co-registrars and one or more additional paying agents.  The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any
        co-registrar.

    

    

    The Issuer shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture.  The agreement shall
      implement the provisions of this Indenture that relate to such agent.  The Issuer shall notify the Trustee in writing of the name and address of each such agent.  If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as
      such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7.  The Issuer or any Guarantor may act as Paying Agent, Registrar or transfer agent.

    

    

    The Issuer initially appoints DTC to act as Depositary with respect to the Global Notes.  The Issuer initially appoints the Trustee as the Registrar and
      Paying Agent for the Notes.  The Issuer may remove any Registrar or Paying Agent without prior notice to the Holders, but upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of any appointment by a successor as
      evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee and the passage of any waiting or notice periods required by DTC procedures or (ii)
      written notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above.  The Registrar or Paying Agent may resign at any time upon written notice to the
      Issuer and the Trustee.

    

    

    SECTION 2.4.          Paying Agent to Hold Money in Trust.  Prior to noon1, New York City time, on each date on which the principal of, premium, if any, or interest on any Note is due and payable, the Issuer shall deposit
        with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium or interest when due.  The Issuer shall require the Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in
        trust for the benefit of Holders and the Trustee all money held by such Paying Agent for the payment of principal of, premium, if any, or interest on the Notes (whether such assets have been distributed to it by the Issuer or other obligors on the
        Notes), shall notify the Trustee in writing of any default by the Issuer or any Guarantor in making any such payment and shall during the continuance of any default by the Issuer (or any other obligor upon the Notes) in the making of any payment in
        respect of the Notes, upon the written request of the Trustee, forthwith deliver to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Notes together with a full accounting thereof.  If the Issuer or a Subsidiary
        of the Issuer acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund for the benefit of the Trustee and the Holders.  The Issuer at any time may require a Paying Agent (other than the
        Trustee) to pay all money held by it to the Trustee and to account for any funds or assets disbursed by such Paying Agent.  Upon complying with this Section 2.4, the
        Paying Agent (if other than the Issuer or a Subsidiary of the Issuer) shall have no further liability for the money

    

    

    

    1 Note to Draft: Matches existing indentures.

    
      13

      
        


    

    

    

    delivered to the Trustee.  Upon any bankruptcy, reorganization or similar proceeding with respect to the Issuer, the Trustee shall serve as Paying Agent for the Notes.

    

    

    SECTION 2.5.          Holder Lists.  The Registrar shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders.  If the Trustee is not the
        Registrar, the Issuer, on its own behalf and on behalf of each of the Guarantors, shall furnish or cause the Registrar to furnish to the Trustee, in writing, at least (i) five (5) calendar days before each interest payment date and (ii) at such
        other times as the Trustee may reasonably request, within 30 days after receipt by the Issuer of any such request, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

    

    

    SECTION 2.6.          Transfer and Exchange.

    

    

    (a)          A Holder may transfer a Note (or a beneficial interest
        therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized denomination by presenting to the Registrar a written request therefor stating the name of the proposed transferee or
        requesting such an exchange, accompanied by any certification, opinion or other document required by this Section 2.6.  The Registrar will promptly register any transfer
        or exchange that meets the requirements of this Section 2.6 by noting the same in the Notes Register maintained by the Registrar for the purpose, and no transfer or
        exchange will be effective until it is registered in such Notes Register.  The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section 2.6 and Section 2.1(f) and (g), as applicable, and, in the
        case of a Global Note (or a beneficial interest therein), the applicable rules and procedures of DTC, Euroclear and Clearstream.  The Registrar shall refuse to register any requested transfer or exchange that does not comply with this Section 2.6.

    

    

    (b)          Transfers of Rule 144A Notes.  The following provisions shall apply with respect to any proposed registration of transfer of a Rule 144A Note prior to the date that is six months (or one year if the holding period under
        Rule 144 then applicable to such Note is one year) after the later of the Issue Date and the last date on which the Issuer or any Affiliate of the Issuer was the owner of such Notes (or any predecessor thereto):

    

    

    (1)          a registration of
        transfer of a Rule 144A Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee in the form as set forth on the reverse of the Note that it is purchasing for its own account or an account with respect
        to which it exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it
        has received such information regarding the Issuer as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in
        order to claim the exemption from registration provided by Rule 144A; provided that no such written representation or other written certification shall be
        required in connection with the transfer of a beneficial interest in the Rule 144A Global Note to a transferee in the form of a beneficial interest in that Rule 144A Global Note in accordance with this Indenture and the applicable procedures of
        DTC; and

    

    

    (2)          a registration of
        transfer of a Rule 144A Note or a beneficial interest therein to a Non‐U.S. Person shall be made upon receipt by the Issuer and the Registrar or its agent of a certificate substantially in the form set forth in Exhibit C from the proposed transferee and the delivery of an Opinion of Counsel, certification and/or other information satisfactory to it.

    

    

    (c)          Transfers of Regulation S Notes.  The following provisions shall apply with respect to any proposed transfer of a Regulation S Note prior to the expiration of the Restricted Period:

    

    

    (1)          a transfer of a
        Regulation S Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee, in the form of assignment on the reverse of the certificate, that it is purchasing the Note for its own account or an account with
        respect to which it exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, is aware that the sale to it is being made in reliance on Rule 144A and acknowledges
        that it has received such information regarding the Issuer as the undersigned has requested pursuant to Rule 144A or

    
      14

      
        


    

    

    

    has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim
      the exemption from registration provided by Rule 144A; and

    

    

    (2)          a transfer of a
        Regulation S Note or a beneficial interest therein to a Non‐U.S. Person shall be made upon receipt by the Registrar or its agent of a certificate substantially in the form set forth in Exhibit








            C from the proposed transferee and receipt by the Registrar or its agent of an Opinion of Counsel, certification and/or other information satisfactory to the Issuer.

    

    

    (d)          Restricted Notes Legend.  Upon the transfer, exchange or replacement of Notes not bearing a Restricted Notes Legend, the Registrar shall deliver Notes that do not bear a Restricted Notes Legend.  Upon the transfer, exchange
        or replacement of Notes bearing a Restricted Notes Legend, the Registrar shall deliver only Notes that bear a Restricted Notes Legend unless (1) a Note is being transferred pursuant to an effective registration statement or (2) there is delivered
        to the Registrar an Opinion of Counsel satisfactory to it stating that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.  Any Additional Notes sold
        in a registered offering shall not be required to bear the Restricted Notes Legend.

    

    

    (e)          Retention of Written Communications.  The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.1
        or this Section 2.6, in accordance with applicable law and the Registrar’s customary procedures.  The Issuer shall have the right to inspect and make copies of all such
        letters, notices or other written communications at any reasonable time upon the giving of reasonable prior written notice to the Registrar.

    

    

    (f)          Obligations with Respect to Transfers and Exchanges of Notes.  To permit registrations of transfers and exchanges, the Issuer shall, subject to the other terms and conditions of this Article II, execute and the Trustee shall authenticate Definitive Notes and Global Notes at the Issuer’s and Registrar’s written request.

    

    

    No service charge shall be made to a Holder for any registration of transfer or exchange, but the Issuer may require the Holder to pay a sum sufficient
      to cover any transfer tax, assessment or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charges payable upon exchange or transfer pursuant to Sections 2.2, 2.7, 2.9,
      5.5 or 9.4).

    

    

    The Issuer (and the Registrar) shall not be required to register the transfer of or exchange of any Note (A) for a period beginning (i) fifteen
      (15) calendar days before the mailing of a notice of an offer to repurchase or redeem Notes and ending at the close of business on the day of such mailing or (ii) fifteen (15) calendar days before an interest payment date and ending on such interest
      payment date or (B) called for redemption, except the unredeemed portion of any Note being redeemed in part or any Note not redeemed due to the failure of a condition precedent to the redemption.

    

    

    Prior to the due presentation for registration of transfer of any Note, the Issuer, the Trustee, the Paying Agent or the Registrar may deem and treat the
      person in whose name a Note is registered as the owner of such Note for the purpose of receiving payment of principal of, premium, if any, and (subject to paragraph 2 of the forms of Notes attached hereto as Exhibit A) interest on such Note and for all other purposes whatsoever, including without limitation the transfer or exchange of such Note, whether or not such Note is overdue, and none of the Issuer,
      the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

    

    

    Any Definitive Note delivered in exchange for an interest in a Global Note pursuant to Section 2.1(g)
      shall, except as otherwise provided by Section 2.6(d), bear the applicable legends regarding transfer restrictions applicable to the Definitive Note set forth in Section 2.1(d).

    

    

    All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same
      benefits under this Indenture as the Notes surrendered upon such transfer or exchange.

    

    

    (g)          No Obligation of the Trustee.  The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in, DTC or other Person with respect to the accuracy of the
        records of DTC or its nominee or of any participant or member thereof, with respect to any

    
      15

      
        


    

    

    

    ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than DTC) of any notice (including any
      notice of redemption or purchase) or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to such Notes.  All notices and communications to be given to the Holders and all payments to be made to
      Holders in respect of the Notes shall be given or made only to or upon the order of the registered Holders (which shall be DTC or its nominee in the case of a Global Note).  The rights of beneficial owners in any Global Note shall be exercised only
      through DTC and subject to the applicable rules and procedures of DTC.  The Trustee may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners.

    

    

    The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this
      Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among DTC participants, members or beneficial owners in any Global Note) other than to require delivery of such
      certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express
      requirements hereof.  Neither the Trustee nor any of its agents shall have any responsibility for any actions taken or not taken by DTC.

    

    

    SECTION 2.7.          Mutilated, Destroyed, Lost or Stolen Notes.  If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the
        Issuer shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8‐405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Issuer and the Trustee that such Note has been lost,
        destroyed or wrongfully taken within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to receiving such notification, (b) makes such request to the
        Issuer and the Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8‐303 of the Uniform Commercial Code (a “protected purchaser”) and
        (c) satisfies any other reasonable requirements of the Trustee; provided,
          however, if after the delivery of such replacement Note, a protected purchaser of the Note for which such replacement Note was issued presents for payment or registration such replaced Note, the Trustee and/or the Issuer shall be entitled
        to recover such replacement Note from the Person to whom it was issued and delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of
        any loss, damage, cost or expense incurred by the Issuer or the Trustee in connection therewith.  Such Holder shall furnish indemnity and security sufficient in the judgment of (i) the Trustee to protect the Trustee (acting in any capacity) and
        (ii) the Issuer to protect the Issuer, , from any loss related to such lost, stolen or mutilated note or any replacement thereof.

    

    

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

    

    

    Upon the issuance of any new Note under this Section 2.7, the Issuer may
      require that such Holder pay a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of counsel and of the Trustee) in connection therewith.

    

    

    Subject to the proviso in the initial paragraph of this Section 2.7, every
      new Note issued pursuant to this Section 2.7, in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the
      Issuer, any Guarantor (if applicable) and any other obligor upon the Notes, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and
      proportionately with any and all other Notes duly issued hereunder.

    

    

    The provisions of this Section 2.7 are exclusive and shall preclude (to the
      extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

    

    

    SECTION 2.8.          Outstanding Notes.  Notes outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those paid pursuant to Section 2.7 and those described in this Section 2.8 as not outstanding.  A Note does not cease to
        be outstanding in the event the Issuer or an Affiliate of the Issuer holds the Note; provided, however, that (i) for purposes of determining which Notes are outstanding for consent or voting purposes hereunder, the provisions of Section 12.4
        shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Notes are present at a meeting of Holders of Notes for quorum purposes or have

    
      16

      
        


    

    

    

    consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such
      quorum, consent or vote, only Notes which a Trust Officer of the Trustee actually knows to be held by the Issuer or an Affiliate of the Issuer shall not be considered outstanding.

    

    

    If a Note is replaced pursuant to Section 2.7 (other than a mutilated Note
      surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Note is held by a protected purchaser.  A mutilated Note ceases to be outstanding upon surrender of such
      Note and replacement pursuant to Section 2.7.

    

    

    If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date, money sufficient to pay all
      principal, premium, if any, and accrued interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Holders on that
      date pursuant to the terms of this Indenture or the notice of redemption, if any, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

    

    

    SECTION 2.9.          Temporary Notes.  In the event that Definitive Notes are to be issued under the terms of this Indenture, until such Definitive Notes are ready for delivery, the Issuer may prepare and the Trustee
        shall authenticate temporary Notes.  Temporary Notes shall be substantially in the form, and shall carry all rights, of Definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes.  Without unreasonable delay,
        the Issuer shall prepare and the Trustee shall authenticate Definitive Notes.  After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at any office or agency
        maintained by the Issuer for that purpose and such exchange shall be without charge to the Holder.  Upon surrender for cancellation of any one or more temporary Notes, the Issuer shall execute, and the Trustee shall, upon receipt of an Issuer
        Order, authenticate and make available for delivery in exchange therefor, one or more Definitive Notes representing an equal principal amount of Notes.  Until so exchanged, the Holder of temporary Notes shall in all respects be entitled to the same
        benefits under this Indenture as a Holder of Definitive Notes.

    

    

    SECTION 2.10.          Cancellation.  The Issuer at any time may deliver Notes to the Trustee for cancellation.  The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for
        registration of transfer, exchange or payment.  The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation and dispose of such Notes in accordance with its internal policies and
        customary procedures (subject to the record retention requirements of the Exchange Act and the Trustee) and shall acknowledge such cancellation in writing if so requested by the Issuer.  If the Issuer or any Guarantor acquires any of the Notes,
        such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.10.  The Issuer may not issue new Notes to replace Notes it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

    

    

    At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, transferred, redeemed, repurchased or
      canceled, such Global Note shall be returned by DTC to the Trustee for cancellation or retained and canceled by the Trustee.  At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Notes,
      transferred in exchange for an interest in another Global Note, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced and an adjustment shall be made on the books and records of the Trustee
      (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Notes Custodian, to reflect such reduction.

    

    

    SECTION 2.11.          Payment of Interest; Defaulted Interest.  Interest on any Note which is payable, and is punctually paid or duly provided for, on any interest payment date shall be paid to the Person in whose name
        such Note (or one or more Predecessor Notes) is registered at the close of business on the regular record date for such payment at the office or agency of the Issuer maintained for such purpose pursuant to Section 2.3.

    

    

    Any interest on any Note which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days
      shall forthwith cease to be payable to the Holder on the regular record date, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne

    
      17

      
        


    

    

    

    by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”)








      shall be paid by the Issuer, at its election in each case, as provided in clause (a) or (b) below:

    

    

    (a)          The Issuer may elect to make payment of any Defaulted
        Interest to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the
        following manner.  The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date (not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted
        Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided
        in this Section 2.11(a).  Thereupon the Issuer shall fix a record date (the “Special Record Date”)








        for the payment of such Defaulted Interest, which date shall be not more than fifteen (15) calendar days and not less than ten (10) calendar days prior to the Special Interest Payment Date and not less than ten (10) calendar days after the receipt
        by the Trustee of the notice of the proposed payment.  The Issuer shall promptly notify the Trustee in writing of such Special Record Date, and in the name and at the expense of the Issuer, the Trustee shall cause notice of the proposed payment of
        such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 12.1, not less than ten
        (10) calendar days prior to such Special Record Date.  Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on
        the Special Interest Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the provisions in Section 2.11(b).

    

    

    (b)          The Issuer may make payment of any Defaulted Interest in
        any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Issuer to the Trustee of the
        proposed payment pursuant to this Section 2.11(b), such manner of payment shall be deemed practicable by the Trustee.

    

    

    Subject to the foregoing provisions of this Section 2.11, each Note
      delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

    

    

    SECTION 2.12.          CUSIP and ISIN Numbers.  The Issuer in issuing the Notes may use “CUSIP” and “ISIN” numbers and, if so, the Trustee may use “CUSIP” and “ISIN” numbers in notices of redemption or purchase as a
        convenience to Holders; provided, however, that any such notice may
        state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on
        the Notes, and any such redemption or purchase shall not be affected by any defect in or omission of such CUSIP and ISIN numbers.  The Issuer shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

    SECTION 3.2.          Limitation on Liens.

    

    

    (a)          Nothing in this Indenture or in the Notes shall in any
        way restrict or prevent the Issuer or any Subsidiary from incurring any indebtedness; provided that the Issuer hereby agrees that neither it nor any
        Restricted Subsidiary will issue, assume or guarantee any Debt secured by a Mortgage upon any Principal Property, or upon any shares of stock of any Restricted Subsidiary, without effectively providing that the Notes (together with, if the Issuer
        so determines, any other indebtedness or obligation then existing and any other indebtedness or obligation, thereafter created, ranking equally with or prior to the Notes) shall be secured equally and ratably with (or, at the option of the Issuer,
        prior to) such Debt so long as such Debt shall be so secured, except that the foregoing provisions shall not apply to:

    

    

    (1)          Mortgages existing on
        the date of this Indenture;

    

    

    (2)          Mortgages affecting
        property of a corporation existing at the time it becomes a Restricted Subsidiary or at the time it is merged into or consolidated with the Issuer or a Restricted Subsidiary;

    

    

    (3)          Mortgages (i) on
        property existing at the time of acquisition thereof, (ii) to secure payment of all or part of the purchase price thereof, (iii) to secure Debt incurred prior to, at the time of or within 24 months after acquisition thereof for the purposes of
        financing all or part of the purchase price thereof or (iv) assumed or incurred in connection with the acquisition of property;

    

    

    (4)          Mortgages on property
        to secure all or part of the cost of repairing, altering, constructing, improving, exploring, drilling or developing such property, or to secure Debt incurred to provide funds for any such purpose;

    

    

    (5)          Mortgages in
        connection with non-recourse Debt;

    

    

    (6)          Mortgages on current
        assets or other personal property (other than shares of stock or indebtedness of Subsidiaries) to secure loans maturing not more than one year from the date of the creation thereof or to secure any renewal thereof for not more than one year at any
        one time;

    

    

    (7)          Mortgages which
        secure indebtedness owing by a Restricted Subsidiary to the Issuer or a Subsidiary;

    

    

    (8)          Mortgages on property
        of any Restricted Subsidiary principally engaged in a financing or leasing business;

    

    

    (9)          Mortgages which do
        not in the aggregate materially detract from the value of the property or assets affected thereby or materially impair the use of such property or assets in the operation of its business; and

    

    

    (10)         any extension,
        renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Mortgage referred to in the foregoing or of any Debt secured thereby, provided that the principal amount of Debt secured thereby shall not,
        with respect to Mortgages referred to in clauses (i) through (iv) above, exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement Mortgage shall be limited
        to all or part of substantially the same property which secured the Mortgage extended, renewed or replaced (plus improvements on such property).

    

    

    (b)          Notwithstanding the foregoing provisions of this
        Section, the Issuer and any one or more Restricted Subsidiaries may issue, assume or guarantee Debt secured by Mortgages which would not be permitted

    

    

    
      19

      
        


    

    

    

    under Section 3.2(a) without equally and ratably securing the Notes in an aggregate principal
      amount which, together with (i) the aggregate outstanding principal amount of all other Debt of the Issuer and its Restricted Subsidiaries which would not be permitted under Section
          3.2(a) and (ii) the Attributable Debt in respect of Sale and Lease-Back Transactions existing at such time (other than Sale and Lease-Back Transactions in which the property involved would have been permitted to be mortgaged under Section 3.2(a) or the proceeds of which have been applied in accordance with Section 3.3(a)(ii)), does not at the time of the issuance, assumption or guarantee of such Debt
      exceed 15% of Consolidated Net Tangible Assets.

    

    

    (c)          For purposes of Sections 3.2 and 3.3, the following types of transactions shall not be deemed to create Debt secured by a Mortgage:

    

    

    (1)          the sale or other
        transfer of any interest in property of the character commonly referred to as a “production payment”; and

    

    

    (2)          a Mortgage in favor
        of the United States of America, any of its territories or possessions, or any state thereof, or any department, agency, instrumentality or political subdivision of any thereof, or any department, agency or instrumentality of any such political
        subdivision, to secure partial progress, advance or other payments pursuant to any contract or statute or to secure any indebtedness incurred for the purpose of financing all or any part of the purchase price or the cost of constructing or
        improving the property subject to such Mortgage.

    

    

    SECTION 3.3.          Limitation on Sale and Lease-Back Transactions.

    

    

    (a)          The Issuer shall not, nor shall it permit any Restricted
        Subsidiary to, enter into any arrangement with any person providing for the leasing by the Issuer or a Restricted Subsidiary of any Principal Property (except for temporary leases for terms of not more than three years or between the Issuer or a
        Subsidiary and a Restricted Subsidiary), title to which property has been or is to be sold or transferred by the Issuer or such Restricted Subsidiary to such person (such transaction herein referred to as a “Sale and Lease-Back Transaction”), unless the proceeds of such sale or transfer are at least equal to the fair value (as determined by the Board of Directors) of such property and either (i) the
        Issuer or such Restricted Subsidiary would be entitled to incur, assume or guarantee Debt secured by a Mortgage on the Principal Property to be leased without equally and ratably securing the Notes pursuant to Section 3.2(a) or (ii) the Issuer shall, and in any such case the Issuer covenants that it will, apply an amount equal to the fair value (as determined by the Board of Directors) of the property so
        leased to the retirement, within 90 days of the effective date of any such Sale and Lease-Back Transaction, of Debt of the Issuer or any Restricted Subsidiary which by its terms matures at, or is extendible or renewable at the option of the obligor
        to, a date more than twelve months after the date of the creation of such Debt and which ranks prior to or on a parity with the Notes; provided, however, that the term Sale and Lease-Back Transaction shall not include any arrangement with the United States of America, any of its territories or possessions,
        or any state thereof, or any department, agency, instrumentality or political subdivision of any thereof, or any department, agency or instrumentality of any such political subdivision, entered into for the purpose of financing all or any part of
        the purchase price or the cost of constructing or improving the property subject to such arrangement.

    

    

    (b)          Notwithstanding Section 3.3(a), the Issuer or any Restricted Subsidiary may enter into any Sale and Lease-Back Transaction which would otherwise be subject to the foregoing restrictions if the amount of the
        Attributable Debt in respect of Sale and Lease-Back Transactions for such transaction, together with (a) the aggregate outstanding principal amount of all Debt of the Issuer and its Restricted Subsidiaries secured by Mortgages upon Principal
        Property or shares of stock of any Restricted Subsidiary which such Debt would not otherwise be permitted under Section 3.2(a) and (b) all other Attributable Debt in respect of Sale and Lease-Back Transactions existing at such time (other than Sale and Lease-Back Transactions in which the property involved would have been
        permitted to be mortgaged under Section 3.2(a) without equally and ratably securing the Notes or the proceeds of which have been applied in accordance with Section 3.3(a)(ii)), does not at the time exceed 15% of Consolidated Net Tangible Assets.

    

    

    SECTION 3.4.          Future Guarantees.  If, after the Issue Date, any wholly owned Restricted Subsidiary (a) creates, assumes or incurs any Specified Unsecured Debt or guarantees any Specified Unsecured Debt, in each
        case issued by the Issuer or any wholly owned Restricted Subsidiary after the Issue Date or (b) guarantees the obligations of Blue Cube under the Blue Cube Notes, then in any such case the Issuer shall cause such wholly owned Restricted

    
      20

      
        


    

    

    

    Subsidiary, within 45 days from (or, in the case of the first guarantee required under clause (b) above after the Issue Date, substantially concurrent with) such creation,
      assumption, incurrence or guarantee of such Specified Unsecured Debt or such guarantee of the Blue Cube Notes, to execute and deliver a supplemental indenture to this Indenture substantially in the form of Exhibit B to provide a Note Guarantee by
      such Restricted Subsidiary of the payment of the principal of, premium, if any, and interest on the Notes on an unsecured unsubordinated basis, except that no such guarantee of the Notes will be required (i) as a result of any indebtedness (including
      any guarantees) by a Person (x) existing at the time such Person is merged into, or consolidated with, any Restricted Subsidiary, (y) existing at the time such Person becomes a Restricted Subsidiary or (z) being assumed by a Restricted Subsidiary in
      connection with a sale, lease or other disposition of the properties and assets of such Person (or a division thereof) as an entirety or substantially as an entirety to any Restricted Subsidiary; provided that in each case any such indebtedness or
      guarantee was not incurred in contemplation thereof, (ii) by any Restricted Subsidiary that is prohibited by any applicable law, rule, regulation or contractual obligation (other than any contractual obligation created in contemplation of such
      incurrence or guarantee) from guaranteeing the Notes or (iii) by any Restricted Subsidiary that would require governmental (including regulatory) consent, approval, license or authorization to provide a guarantee of the Notes (unless such consent,
      approval, license or authorization has been received).  If the Issuer is required to cause a Restricted Subsidiary to provide a Note Guarantee pursuant to the immediately preceding sentence as a result of such Restricted Subsidiary’s guarantee of the
      Blue Cube Notes and, at the time such Note Guarantee is provided Blue Cube is not a Guarantor, the Issuer shall cause Blue Cube to execute and deliver a supplemental indenture to this Indenture substantially in the form of Exhibit B to provide a Note
      Guarantee substantially concurrent with such Restricted Subsidiary’s guarantee of the Blue Cube Notes.

    

    

    SECTION 3.5.          Change of Control Repurchase Event.

    

    

    (a)          If a Change of Control Repurchase Event occurs, unless
        the Issuer has exercised its right to redeem the Notes as provided in this Indenture, the Issuer shall make an offer to each Holder of Notes to repurchase all or any part (in integral multiples of $1,000 principal amount) of that Holder’s Notes at
        a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the date of purchase.  Within 30 days following any Change of Control Repurchase Event
        or, at the Issuer’s option, prior to any Change of Control, but after a definitive agreement is in place for a Change of Control, the Issuer will deliver a notice to each Holder, and provide notice to the Trustee, describing the transaction or
        transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date
        such notice is delivered.  The notice shall, if delivered prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment
        date specified in the notice.  The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with
        the repurchase of the Notes as a result of a Change of Control Repurchase Event.  To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Issuer shall
        comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

    

    

    (b)          On the Change of Control Payment Date, the Issuer will,
        to the extent permitted by law,

    

    

    (1)          accept for payment
        all Notes or portions of Notes properly tendered pursuant to the Issuer’s offer;

    

    

    (2)          deposit with the
        Paying Agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes properly tendered; and

    

    

    (3)          deliver or cause to
        be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchased by the Issuer.

    

    

    (c)          The Paying Agent shall promptly deliver to each Holder
        of Notes properly tendered the purchase price for the Notes, and the Issuer will execute and direct the Trustee to promptly authenticate and deliver to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes
        surrendered; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

    
      21

      
        


    

    

    

    (d)          The Issuer will not be required to make an offer to
        repurchase the Notes upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and such third party purchases all Notes
        properly tendered and not withdrawn under its offer.

    

    

    (e)          In addition, an offer to repurchase may be made in
        advance of a Change of Control Repurchase Event, conditional upon such Change of Control Repurchase Event, if a definitive agreement is in place for a Change of Control at the time of launching the offer to repurchase.

    

    

    SECTION 3.6.          Reports.

    

    

    (a)          Whether or not required by the Commission, so long as
        any Notes are outstanding, the Issuer shall furnish to the Holders, or file electronically with the Commission through the Commission’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system), within the time periods
        specified in the Commission’s rules and regulations:

    

    

    (1)          all quarterly and
        annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Issuer were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and
        Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Issuer’s certified independent accountants; and

    

    

    (2)          all current reports
        that would be required to be filed with the Commission on Form 8-K if the Issuer were required to file such reports.

    

    

    In addition, whether or not required by the Commission, the Issuer shall file a copy of all of the information and reports referred to in clauses (1) and
      (2) above with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept such a filing) and make such information available to prospective investors.

    

    

    (b)          To the extent not satisfied by the information required
        under Section 3.6(a), the Issuer shall, for so long as any Notes are outstanding, furnish to Holders and prospective investors, upon their request, the information
        required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

    

    

    (c)          Delivery under this Section 3.6 of reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information
        contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee, subject to Section








            7.1 hereof, is entitled to rely exclusively on Officers’ Certificates).  The Trustee shall have no liability or responsibility for the filing, timeliness or content of any such report.

    

    

    SECTION 3.7.          Maintenance of Office or Agency.

    

    

    The Issuer will maintain an office or agency where the Notes will be payable at the office or agency of the Issuer maintained for such purpose and where,
      if applicable, the Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be delivered.  The Corporate Trust Office of the Trustee, which
      initially shall be located at 60 Livingston Avenue, 1st Fl., St. Paul, Minnesota 55107, Attention Corporate Trust Services, shall be such office or agency of the
      Issuer unless the Issuer shall designate and maintain some other office or agency for one or more of such purposes.  The Issuer will give prompt written notice to the Trustee of any change in the location of any such office or agency.  If at any time
      the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the Corporate Trust Office of the Trustee, and the Issuer hereby
      appoints the Trustee as its agent to receive all such presentations and surrenders.

    

    

    The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such
      purposes and may from time to time rescind any such designation.

    
      22

      
        


    

    

    

    The Issuer will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

    

    

    SECTION 3.8.          Compliance Certificate.  The Issuer shall deliver to the Trustee within 120 days after the end of each fiscal year of the Issuer a certificate, signed by the principal executive officer, the
        principal financial officer or the principal accounting officer of the Issuer, stating that in the course of the performance by the signer of his or her duties as an Officer of the Issuer he or she would normally have knowledge of any Default or
        Event of Default and whether or not the signer knows of any Default or Event of Default that occurred during the previous fiscal year; provided that no such
        certificate shall be required for any fiscal year ended prior to the Issue Date.  If such Officer does have such knowledge, the certificate shall describe the Default or Event of Default, its status and the action the Issuer is taking or proposes
        to take with respect thereto.

    

    

    SECTION 3.9.          Further Instruments and Acts.  Upon request of the Trustee or as necessary to comply with future developments or requirements, the Issuer will execute and deliver such further instruments and do such
        further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

    

    

    SECTION 3.10.          Statement by Officers as to Default.  The Issuer shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any events of which it is aware which would constitute a
        Default or Event of Default, their status and what action the Issuer is taking or proposes to take in respect thereof and the Trustee shall not be deemed to have notice of any such Default or Event of Default until a Trust Officer actually receives
        notice thereof.

    (1)          the successor Person
        (if other than the Issuer) will be a corporation organized under the laws of the United States of America or any State thereof or the District of Columbia and shall expressly assume the due and punctual payment of the principal of and premium, if
        any, and interest on all the Notes, according to their tenor, and the due and punctual performance and observance of all of the covenants and conditions of this Indenture to be performed or observed by us, by supplemental indenture satisfactory in
        form to the Trustee, executed and delivered to the Trustee by such Person;

    

    

    (2)          the successor Person
        shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance of any such covenant or condition; and

    (c)          Any Restricted Subsidiary of the Issuer may consolidate

    REDEMPTION OF NOTES

     

      

    SECTION 5.1.          Selection.  If less than all of the Notes are to be redeemed at any time, the Trustee will select the Notes for redemption on a pro rata basis to the extent practicable3 or in such manner
        as it shall deem fair and appropriate, subject to applicable requirements of the principal securities exchange, if any, on which the Notes are listed, as certified to the Trustee by the Issuer, and the applicable requirements of DTC; provided, however, that no Note of $2,000 in aggregate principal amount
        or less will be redeemed in part.

    

    

    SECTION 5.2.          Notice of Redemption.

    

    

    (a)          The Issuer shall cause notices of redemption to be
        delivered at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address (or sent electronically in accordance with the applicable procedures of the Depositary in the case of Global
        Notes), except that redemption notices may be sent more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of Notes or a satisfaction and discharge of this Indenture.  Any inadvertent defect in the
        notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption will not impair or affect the validity of the redemption of any other Note redeemed in accordance with provisions of this Indenture.

    

    

    The notice will identify the Notes (including the CUSIP or ISIN number) to be redeemed and will state:

    

    

    (1)          the date of
        redemption (the “Redemption Date”);

    

    

    (2)          the redemption price;

    

    

    (3)          if any Note is being
        redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon
        cancellation of the original Note;

    

    

    (4)          the name and address
        of the Paying Agent;

    

    

    (5)          that Notes called for
        redemption must be surrendered to the Paying Agent to collect the redemption price;

    

    

    (6)          that, unless the
        Issuer defaults in making such redemption payment, interest on Notes called for redemption cease to accrue on and after the Redemption Date;

    

    

    (7)          any condition
        precedent to the redemption and related information as required by Section 5.3;

    

    

    (8)          the paragraph of the
        Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

    

    

    (9)          that no
        representation is made as to the correctness or accuracy of the CUSIP or ISIN number listed in such notice or printed on the Notes.

    

    

    (b)          If any Note is to be redeemed in part only, the notice
        of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed.  Notes held in certificated form must be surrendered to the Trustee or Paying Agent in order to collect the redemption price.  Unless the
        Issuer defaults in the payment of the redemption price (and subject to the prior satisfaction (or waiver by the Issuer) of any conditions precedent to the redemption), on and after the Redemption Date, interest ceases to accrue on Notes or portions
        of them called for redemption.

    

    

    

    3 Note to Draft: This formulation matches the Description of Notes.

    
      24

      
        


    

    

    

    (c)          For Notes which are represented by global certificates
        held on behalf of DTC, notices may be given by delivery of the relevant notices to DTC, in accordance with their procedures for communication to entitled account holders in substitution for the aforesaid electronic delivery or first-class mailing.

    

    

    (d)          At the Issuer’s request, the Trustee shall give the
        notice of redemption in the Issuer’s name and at the Issuer’s expense.  In such event, the Issuer shall provide the Trustee with an Officers’ Certificate containing the information required by this Section 5.2 at least five (5) Business Days prior to the date on which the Issuer instructs the Trustee to send the notice (or such shorter period as the Trustee may agree).  If the Trustee is to select the Notes to be
        redeemed in any partial redemption, the Issuer shall instruct the Trustee in writing at least five (5) Business Days prior to such selection.

    

    

    SECTION 5.3.          Effect of Notice of Redemption.  Subject to the following four sentences, once notice of redemption is sent in accordance with Section 5.2,
        Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price.  Notice of any redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent.  If at any time the relevant
        conditions precedent are not satisfied (or waived by the Issuer), the Issuer may, in its discretion, rescind such notice or amend it on one or more occasions to specify another Redemption Date until the satisfaction (or waiver by the Issuer) of any
        such conditions precedent, unless such notice is earlier rescinded by the Issuer as described above. Subject to the foregoing, Notes called for redemption become due on the date fixed for redemption.  Written notice of redemption will be provided
        as set forth under Section 5.2. In addition, the Issuer may provide in such written notice that payment of the redemption price and performance of the Issuer’s
        obligations with respect to such redemption may be performed by another person.

    

    

    SECTION 5.4.          Deposit of Redemption or Purchase Price.  Prior to noon, New York City time, on the redemption or purchase date, the Issuer will deposit with the Trustee or with the Paying Agent money sufficient to
        pay the redemption or purchase price of and accrued interest, if any, on, all Notes to be redeemed or purchased on that date.  The Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Paying
        Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest, if any, on, all Notes to be redeemed or purchased.

    

    

    If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the
      Notes or the portions of Notes called for redemption or purchase.  If a Note is redeemed or purchased on or after a record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in
      whose name such Note was registered at the close of business on such record date, and no other interest will be payable to Holders whose Notes will be subject to redemption by the Issuer.  If any Note called for redemption or purchase is not so paid
      upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the
      extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 3.1.

    

    

    SECTION 5.5.          Notes Redeemed or Purchased in Part.  Upon surrender of a Note that is redeemed or purchased in part, the Issuer will issue and, upon receipt of an Issuer
          Order, the Trustee will authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered; provided, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

    

    

    SECTION 5.6.          Optional Redemption.

    

    

    (a)          Except as set forth in Sections 5.6(b) and (c), the Notes are not redeemable at the option of the Issuer.

    

    

    (b)          At any time prior to the Par Call Date, the Issuer may redeem the Notes at its option, in whole at any time or in part from time to time prior to the Par Call Date,
          upon notice as required under Section 5.2, at a redemption price equal to 100% of the principal amount
            of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but excluding, the Redemption Date, subject to the rights of the Holders of record on the relevant record date to receive interest due on the
            relevant interest payment date.

    
      25

      
        


    

    

    

    (c)          At any time on or after the Par Call Date, the Issuer may redeem the Notes at its option, in whole at any time or in part from time to time on or after the Par Call Date, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date, subject to the rights of the Holders of
          record on the relevant record date to receive interest due on the relevant interest payment date.

    

    

    (d)          Any redemption pursuant to this Section 5.6 shall be made pursuant to the provisions of Sections 5.1 through 5.5.

    

    

    SECTION 5.7.          Mandatory Redemption.  The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes; provided, however, that under certain circumstances, the Issuer may be required to offer to purchase Notes under Section 3.5.  The Issuer may at any time and from time to time purchase Notes in the open market or otherwise.

    DEFAULTS AND REMEDIES

    

    

    SECTION 6.1.          Events of Default.

    

    

    (a)          Each of the following is an “Event of Default”:

    

    

    (1)          default in the
        payment in respect of the principal of (or premium, if any, on) any Note when due and payable (whether at Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise);

    

    

    (2)          default in the
        payment of any interest upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days;

    

    

    (3)          default in the
        performance, or breach, of any covenant or agreement of the Issuer or any Subsidiary in this Indenture (other than a covenant or agreement a default in the performance of which or the breach of which is specifically dealt with in clauses (1) or (2)
        above), and continuance of such default or breach for a period of 60 days after written notice thereof has been given to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25% in aggregate principal amount of the
        outstanding Notes (provided that, and without limiting the foregoing in this clause (3), in the case of a default or breach of any covenant or agreement set
        forth in Section 3.6, no Event of Default shall occur (and any such default or breach shall be deemed to not have occurred for all purposes under this Indenture) with
        respect to any failure to furnish or file any information or report required thereunder if the Issuer files or furnishes such information or report within 120 days after the Issuer was required (or would have been required) to file the same
        pursuant to the Commission’s rules and regulations); and

    

    

    (4)          (i) the Issuer or any
        Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

    

    

    (A)          commences a
        voluntary case;

    

    

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

    

    

    (C)          consents to the
        appointment of a custodian of it or for all or substantially all of its property;

    

    

    (D)          makes a general
        assignment for the benefit of its creditors; or

    

    

    (E)          generally is not
        paying its debts as they become due; or

    

    

    
      26

      
        


    

    

    

    (ii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

    

    

    (A)          is for relief
        against the Issuer or any Significant Subsidiary, in an involuntary case;

    

    

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

    

    

    (C)          orders the
        liquidation of the Issuer or any Significant Subsidiary;

    

    

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

    

    

    SECTION 6.2.          Acceleration.

    

    

    (a)          If an Event of Default (other than an Event of Default
        specified in clause (4) of Section 6.1 with respect to the Issuer) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25%
        in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Issuer (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment
        or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of or interest on
        the Notes, have been cured or waived as provided in this Indenture.

    

    

    (b)          If an Event of Default specified in clause (4) of Section 6.1 occurs with respect to the Issuer, the principal of and any accrued interest on the Notes then outstanding shall ipso facto become immediately due and payable
        without any declaration or other act on the part of the Trustee or any Holder.

    

    

    SECTION 6.3.          Other Remedies.  If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or premium, if
        any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

    

    

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

    

    

    SECTION 6.4.          Waiver of Past Defaults.  The Holders of not less than a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes
        waive any existing Default or Event of Default with respect to the Notes and its consequences under this Indenture except any such Default or Event of Default (1) in any payment in respect of the principal of (or premium, if any) or interest on any
        Notes, or (2) in respect of a covenant or provision of this Indenture which under the terms hereof cannot be modified or amended without the consent of the Holder of each outstanding Note affected, which in either case shall require the consent of
        all of the Holders of the Notes then outstanding.

    

    

    SECTION 6.5.          Control by Majority.  The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee
        of exercising any trust or power conferred on the Trustee.  However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or the Notes or, subject to Sections 7.1 and 7.2, that the Trustee determines is unduly prejudicial to the rights of other Holders (it being understood that the Trustee does
        not have an affirmative duty to ascertain whether or not any actions are unduly prejudicial to such Holders) or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.  Prior to taking any such action
        hereunder, the Trustee shall be entitled to indemnification satisfactory to it against all fees, losses and expenses (including attorney’s fees and expenses) that may be caused by taking or not taking such action.

    
      27

      
        


    

    

    

    SECTION 6.6.          Limitation on Suits.  No Holder of any Note will have any right to institute any proceeding with respect to this Indenture or for any remedy thereunder, unless such Holder shall have previously given
        to the Trustee written notice of a continuing Event of Default and unless also the Holders of at least 25% in aggregate principal amount of the outstanding Notes shall have made written request to the Trustee, and provided indemnity satisfactory to
        the Trustee, to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request and the Trustee shall
        have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder of a Note directly (as opposed to through the Trustee) for enforcement of payment of the principal of (and premium, if
        any) or interest on such Note on or after the respective due dates expressed in such Note.

    

    

    SECTION 6.7.          Rights of Holders to Receive Payment.  Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, or interest, on the Notes
        held by such Holder, on or after the respective due dates expressed or provided for in the Notes, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of
        such Holder.

    

    

    SECTION 6.8.          Collection Suit by Trustee.  If an Event of Default specified in clauses (1) or (2) of Section 6.1 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an
        express trust against the Issuer for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.7.

    

    

    SECTION 6.9.          Trustee May File Proofs of Claim.  The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any
        claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to Holdings, the Issuer, its Subsidiaries or its or their respective
        creditors or properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter and may vote on behalf of the Holders in any
        election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent
        to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee hereunder.

    

    

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

    

    

    SECTION 6.10.          Priorities.

    

    

    (a)          If the Trustee collects any money or property pursuant
        to this Article VI it shall pay out the money or property in the following order:

    

    

    FIRST:  to the Trustee (acting in any capacity) for amounts due to it hereunder;

    

    

    SECOND:  to Holders for amounts due and unpaid on the Notes for principal of, or premium, if any, and interest, ratably, without
      preference or priority of any kind, according to the amounts due and payable on the Notes for principal of, or premium, if any, and interest, respectively; and

    

    

    THIRD:  to the Issuer, or to the extent the Trustee collects any amount from any Guarantor, to such Guarantor.

    

    

    (b)          The Trustee may fix a record date and payment date for
        any payment to Holders pursuant to this Section 6.10.  At least fifteen (15) days before such record date, the Issuer shall send or cause to be sent to each Holder and
        the Trustee a notice that states the record date, the payment date and amount to be paid.

    

    

    
      28

      
        


    

    

    

    SECTION 6.11.          Undertaking for Costs.  In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it, a court in its discretion
        may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
        the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant.  This Section 6.11 does not apply to a suit by the Trustee,
        a suit by the Issuer, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in outstanding principal amount of the Notes.

    TRUSTEE

    

    

    SECTION 7.1.          Duties of Trustee.

    

    

    (a)          If an Event of Default has occurred and is continuing,
        the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such person’s own affairs.

    

    

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

    

    

    (1)          the Trustee
        undertakes to perform such duties and only such duties as are specifically set forth as duties of the Trustee in this Indenture or the Notes, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

    

    

    (2)          in the absence of
        willful misconduct on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates, opinions or orders furnished to the Trustee and conforming to the
        requirements of this Indenture or the Notes, as the case may be.  However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such
        certificates and opinions to determine whether or not they conform to the requirements of this Indenture or the Notes, as the case may be (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

    

    

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

    

    

    (1)          this Section 7.1(c) does not limit the effect of Section 7.1(b);

    

    

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

    

    

    (3)          the Trustee shall not
        be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5; and

    

    

    (4)          no provision of this
        Indenture or the Notes shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or thereunder or in the exercise of any of its rights or powers.

    

    

    (d)          Every provision of this Indenture that in any way
        relates to the Trustee is subject to clauses (a), (b) and (c) of this Section 7.1.

    

    

    (e)          The Trustee shall not be liable for interest on any
        money received by it except as the Trustee may agree in writing with the Issuer.

    

    

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

    

    

    
      29

      
        


    

    

    

    (g)          Every provision of this Indenture relating to the
        conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.1.

    

    

    SECTION 7.2.          Rights of Trustee.  Subject to Section 7.1:

    

    

    (a)          The Trustee may conclusively rely on and shall be fully
        protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order or other paper or document (whether in its original or facsimile form) reasonably
        believed by it to be genuine and to have been signed or presented by the proper Person.  The Trustee need not investigate any fact or matter stated in the document.  The Trustee shall receive and retain financial reports and statements of the
        Issuer as provided herein, but shall have no duty to review or analyze such reports or statements to determine compliance with covenants or other obligations of the Issuer.

    

    

    (b)          Unless this Indenture provides otherwise, before the
        Trustee acts or refrains from acting, it may require an Officers’ Certificate and/or an Opinion of Counsel.  The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officers’ Certificate or Opinion
        of Counsel.

    

    

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

    

    

    (d)          The Trustee shall not be liable for any action it takes
        or omits to take in good faith that it believes to be authorized or within its rights or powers conferred upon it by this Indenture.

    

    

    (e)          The Trustee may consult with counsel of its selection,
        and the advice or opinion of counsel relating to this Indenture or the Notes shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder or under the Notes in good faith
        and in reliance on the advice or opinion of such counsel.

    

    

    (f)          The Trustee shall not be deemed to have notice of any
        Default or Event of Default or whether any entity or group of entities constitutes a Significant Subsidiary unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default or
        of any such Significant Subsidiary is received by the Trustee at the Corporate Trust Office of the Trustee specified in Section 3.7, and such notice references the Notes
        and this Indenture.

    

    

    (g)          The rights, privileges, protections, immunities and
        benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act
        hereunder.

    

    

    (h)          The Trustee shall be under no obligation to exercise any
        of the rights or powers vested in it by this Indenture or the Notes at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity
        satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred therein or thereby.

    

    

    (i)          The Trustee shall not be deemed to have knowledge of any
        fact or matter unless such fact or matter is actually known to a Trust Officer of the Trustee.

    

    

    (j)          Whenever in the administration of this Indenture the
        Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may conclusively rely upon an Officers’
        Certificate or Opinion of Counsel or both, as applicable.

    

    

    (k)          The Trustee shall not be bound to make any investigation
        into the facts or matters stated in any resolution, certificate, statement, instrument, report, notice, request, direction, consent, order, bond, debenture, coupon or other paper or document, but the Trustee, in its discretion, may make such
        further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine, during business hours and upon reasonable notice, the
        books, records

    
      30

      
        


    

    

    

    and premises of the Issuer and the Restricted Subsidiaries, personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional
      liability of any kind by reason of such inquiry or investigation.

    

    

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

    

    

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

    

    

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

    

    

    (o)          Unless otherwise specifically provided in this
        Indenture, any demand, request, direction or notice from the Issuer shall be sufficient if signed by one Officer of the Issuer

    

    

    SECTION 7.3.          Individual Rights of Trustee.  The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same
        rights it would have if it were not Trustee.  Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights.  However, the Trustee must comply with Sections 7.10
        and 7.11.  In addition, the Trustee shall be permitted to engage in transactions with the Issuer; provided, however, that if the Trustee acquires any “conflicting interest” (as defined in the TIA), the Trustee must (i)
        eliminate such conflict within 90 days of acquiring such conflicting interest or (ii) resign.

    

    

    SECTION 7.4.          Trustee’s Disclaimer.  The Trustee shall not be responsible for and does not make any representation as to the validity or adequacy of this Indenture or the Notes.  The Trustee shall not be
        accountable for the Issuer’s use of the proceeds from any sale of the Notes, the Trustee shall not be responsible for the use or application of any money received by any Paying Agent (other to the extent the Trustee is the Paying Agent) or any
        money paid to the Issuer pursuant to the terms of this Indenture and the Trustee shall not be responsible for any statement of the Issuer in this Indenture or in any document issued in connection with the issuance of the Notes or in the Notes
        (other than the Trustee’s certificate of authentication).

    

    

    SECTION 7.5.          Notice of Defaults.  If a Default or Event of Default occurs and is continuing and the Trustee is informed of such occurrence by the Issuer, the Trustee must give notice of the Default or Event of
        Default to the Holders within 60 days after being notified by the Issuer. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest on any Note, the Trustee may withhold notice if and so long as
        the Trustee in good faith determines that withholding notice is in the interests of the Holders.

    

    

    SECTION 7.6.          Reports by Trustee to Holders.  Within 60 days after each May 15 beginning May 15, 2021, the Trustee shall transmit to each Holder (with a copy to the Issuer) a brief report dated as of such May 15
        that complies with Section 313(a) of the TIA if and to the extent required thereby.  The Trustee also shall comply with Section 313(c) of the TIA.

    

    

    SECTION 7.7.          Compensation and Indemnity.  The Issuer shall pay to the Trustee (acting in any capacity)  from time to time compensation for its services hereunder and under the Notes as the Issuer and the Trustee
        shall from time to time agree in writing.  The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.  The Issuer shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses
        incurred or made by it, including, but not limited to, costs of collection, costs of preparing reports, certificates and other documents, costs of preparation and transmitting notices to Holders.  Such expenses shall include the reasonable
        compensation and expenses, disbursements and advances of the agents, counsel, accountants and experts of the Trustee.  The Issuer shall indemnify the Trustee (acting in any capacity) against any and all fees, loss, liability, damages, claims or
        expense, including taxes (other than taxes based upon the income of the Trustee) (and also including reasonable attorneys’ and agents’ fees and expenses) incurred by it without willful misconduct or gross negligence, as determined by a court of
        competent jurisdiction in a final non-appealable order, on its part in connection with the administration of this trust and the performance of its duties hereunder and under the Notes, including the fees, costs and expenses of enforcing this
        Indenture (including this Section 7.7) and the

    
      31

      
        


    

    

    

    Notes and of defending itself against any claims (whether asserted by any Holder, the Issuer or otherwise).  The Trustee shall notify the Issuer promptly of any claim for
      which it may seek indemnity of which it has received written notice.  Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder.  The Issuer shall defend the claim and the Trustee shall provide
      reasonable cooperation at the Issuer’s expense in the defense.  The Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel.

    

    

    To secure the Issuer’s payment obligations in this Section 7.7, the Trustee
      shall have a lien prior to the Notes on all money or property held or collected by the Trustee.  Such lien shall survive the satisfaction and discharge of this Indenture.  The Trustee’s respective right to receive payment of any amounts due under
      this Section 7.7 shall not be subordinate to any other liability or Indebtedness of the Issuer.

    

    

    The Issuer’s payment obligations pursuant to this Section 7.7 shall survive
      the discharge of this Indenture and the resignation or removal of the Trustee.  Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs fees, expenses or renders services after the occurrence of a
      Default specified in clause (4) of Section 6.1, the fees and expenses (including the reasonable fees and expenses of its counsel) are intended to constitute expenses of
      administration under any Bankruptcy Law.

    

    

    SECTION 7.8.          Replacement of Trustee.  The Trustee may resign at any time by so notifying the Issuer in writing not less than 30 days prior to the effective date of such resignation.  The Holders of a majority in
        principal amount of the Notes may remove the Trustee by so notifying the removed Trustee in writing not less than 30 days prior to the effective date of such removal and may appoint a successor Trustee with the Issuer’s written consent, which
        consent will not be unreasonably withheld.  The Issuer shall remove the Trustee (and any Holder that has been a bona fide Holder for not less than six months may petition any court for removal of the Trustee and appointment of a successor Trustee)
        if:

    

    

    (1)          the Trustee fails to
        comply with Section 7.10;

    

    

    (2)          the Trustee is
        adjudged bankrupt or insolvent;

    

    

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

    

    

    (4)          the Trustee otherwise
        becomes incapable of acting as trustee hereunder.

    

    

    If the Trustee resigns or is removed by the Issuer or by the Holders of a majority in principal amount of the Notes and such Holders do not reasonably
      promptly appoint a successor Trustee as described in the preceding paragraph, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Issuer shall promptly
      appoint a successor Trustee.

    

    

    A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer.  Thereupon the resignation or
      removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture.  The successor Trustee shall mail a notice of its succession to Holders.  The retiring
      Trustee shall, at the expense of the Issuer, promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.7.

    

    

    If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of at
      least 10% in principal amount of the Notes may petition, at the Issuer’s expense, any court of competent jurisdiction for the appointment of a successor Trustee.

    

    

    If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty
      to resign is stayed as provided in Section 310(b) of the TIA, any Holder, who has been a bona fide holder of a Note for at least six months, may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a
      successor Trustee.

    

    

    Notwithstanding the replacement of the Trustee pursuant to this Section 7.8,
      the Issuer’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.  The predecessor Trustee shall have no liability or responsibility for
      any action or inaction of any successor Trustee.

    

    

    
      32

      
        


    

    

    

    SECTION 7.9.          Successor Trustee by Merger.  If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or
        banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

    

    

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

    

    

    SECTION 7.10.          Eligibility; Disqualification.  This Indenture shall always have a Trustee that satisfies the requirements of Section 310(a)(1), (2) and (5) of the TIA in every respect.  The Trustee shall have a
        combined capital and surplus of at least $100,000,000  as set forth in its most recent published annual report of condition.  The Trustee shall comply with Section 310(b) of the TIA; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the TIA any indenture or indentures
        under which other securities or certificates of interest or participation in other securities of the Issuer are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met.

    

    

    SECTION 7.11.          Preferential Collection of Claims Against the Issuer.  The Trustee shall comply with Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA.  A Trustee who
        has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated.

    

    

    SECTION 7.12.          Trustee’s Application for Instruction from the Issuer.  Any application by the Trustee for written instructions from the Issuer may, at the option of the Trustee, set forth in writing any action
        proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective.  The Trustee shall not be liable for any action taken by, or omission of, the
        Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three (3) Business Days after the date any Officer of the Issuer actually receives such
        application, unless any such Officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to
        such application specifying the action to be taken or omitted.

    

    

    ARTICLE VIII

    

    

    DEFEASANCE AND COVENANT DEFEASANCE

    

    

    SECTION 8.1.          Option to Effect Defeasance or Covenant Defeasance.  The Issuer may, at the option of its Board of Directors evidenced by a resolution of its Board of Directors set forth in an Officers’ Certificate,
        at any time, elect to have either Section 8.2 or 8.3 hereof applied to all outstanding Notes
        and Note Guarantees upon compliance with the conditions set forth below in this Article VIII.

    

    

    SECTION 8.2.          Defeasance.  Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.2, the Issuer and each Guarantor, if any, shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be deemed to have been discharged from its respective obligations with respect to all outstanding Notes and Note Guarantees on the date the conditions set forth below are satisfied (hereinafter, “defeasance”).  For this purpose, defeasance means that the Issuer shall be deemed to have paid and discharged the entire Debt represented by the outstanding Notes, which shall
        thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below,
        and to have satisfied all of its other obligations under such Notes and, to the extent related to such Notes, this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same),
        except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

     

      

    
      33

      
        


    

    

    

    (1)          the rights of Holders
        of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest, if any, on such Notes when such payments are due from the trust referred to in Section








            8.4(l) hereof;

    

    

    (2)          the Issuer’s
        obligations with respect to the Notes under Article II concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and Section 3.7
        concerning the maintenance of an office or agency for payment and money for security payments held in trust;

    

    

    (3)          the rights, powers,
        trusts, duties and immunities of the Trustee and the Issuer’s obligations in connection therewith;

    

    

    (4)          the Issuer’s rights
        under the optional redemption provisions of the Notes; and

    

    

    (5)          the provisions of
        this Article VI with respect to defeasance.

    

    

    Subject to compliance with this Section 8.2, the Issuer may exercise its
      option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3.

    

    

    SECTION 8.3.          Covenant Defeasance.  Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3,
        the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from its obligations under the covenants contained in Section 3.2,
        3.3, 3.4, 3.5
        and 3.6 with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in
        connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes).  For this purpose, covenant defeasance
        means that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or
        indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an
        Event of Default with respect to the Notes, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby.  In addition, upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, clause (4) of Section 6.1 (with respect to any Significant Subsidiary) hereof
        shall not constitute an Event of Default with respect to the Notes.

    

    

    SECTION 8.4.          Conditions to Defeasance or Covenant Defeasance.  In order to exercise either defeasance or covenant defeasance with respect to the Notes under either Section 8.2 or 8.3:

    

    

    (1)          the Issuer must
        irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefit of the Holders of, such
        Notes:  (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money in an
        amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and
        discharge, and which shall be applied by the Trustee to pay and discharge, the entire indebtedness in respect of the principal of and premium, if any, and interest on such Notes on the Stated Maturity thereof or (if the Issuer has made irrevocable
        arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the expense of the Issuer) the redemption date thereof, as the case may be, in accordance with the terms of this Indenture and such
        Notes;

    

    

    (2)          in the case of
        defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that:

    

    

    
      34

      
        


    

    

    

    (i)          the Issuer has
        received from, or there has been published by, the Internal Revenue Service a ruling; or

    

    

    (ii)          since the date of
        this Indenture, there has been a change in the applicable United States federal income tax law;

    

    

    in either case (i) or (ii) to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of such Notes will not recognize gain or loss for
      United States federal income tax purposes as a result of the deposit, defeasance and discharge to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same
      times as would be the case if such deposit, defeasance and discharge were not to occur;

    

    

    (3)          in the case of
        covenant defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such outstanding Notes will not recognize gain or loss for United States federal income tax purposes as a result of the
        deposit and covenant defeasance to be effected with respect to such Notes and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and covenant defeasance were not
        to occur;

    

    

    (4)          no Default with
        respect to the outstanding Notes shall have occurred and be continuing at the time of such deposit after giving effect thereto (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Mortgage
        to secure such borrowing);

    

    

    (5)          such defeasance or
        covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or material instrument (other than this Indenture) to which the Issuer is a party or by which the Issuer is bound; and

    

    

    (6)          the Issuer shall have
        delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with.

    

    

    SECTION 8.5.          Deposited Money and U.S. Government Obligations to be Held in Trust; Other Miscellaneous Provisions.  Subject to Section 8.6,
        all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5,
        the “Trustee”) pursuant to Section 8.4 in respect of the outstanding Notes will be held in
        trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may determine, to the
        Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

    

    

    The Issuer will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S.
      Government Obligations deposited pursuant to Section 8.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law
      is for the account of the Holders of the outstanding Notes.

    

    

    Notwithstanding anything in this Article VIII to the contrary, the Trustee
      will deliver or pay to the Issuer from time to time upon the request of the Issuer any money or U.S. Government Obligations held by it as provided in Section 8.4 which, in
      the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be public accountants delivering the opinion delivered under Section 8.4(1)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent defeasance or covenant defeasance.

    

    

    SECTION 8.6.          Repayment to the Issuer.  Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest, if any, on
        any Note and remaining unclaimed for one year after such principal and premium, if any, or interest has become due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust;
        and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for

     

      

    
      35

      
        


    

    

    

    payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon
      cease; provided, however, that the Trustee or such Paying Agent,
      before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days
      from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer.

    

    

    SECTION 8.7.          Reinstatement.  If the Trustee or Paying Agent is unable to apply any money or U.S. dollars or non-callable U.S. Government Obligations in accordance with Section 8.2 or Section 8.3, as the case may be, by reason of any order or judgment of any court or Governmental Authority enjoining,
        restraining or otherwise prohibiting such application, then the Issuer’s and the Guarantors’ (if any) obligations under this Indenture, the Notes and the Note Guarantees (if applicable) will be revived and reinstated as though no deposit had
        occurred pursuant to Section 8.2 or Section 8.3 until such time as the Trustee or Paying
        Agent is permitted to apply all such money in accordance with Section 8.2 or Section 8.3, as
        the case may be; provided, however, that, if the Issuer makes any
        payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Issuer will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government
        Obligations held by the Trustee or Paying Agent.

    

    

    ARTICLE IX

    

    

    AMENDMENTS

    

    

    SECTION 9.1.          Without Consent of Holders.  Notwithstanding Section 9.2, without the consent of any Holders, the Issuer and the Trustee,
        at any time and from time to time, may enter into one or more indentures supplemental to this Indenture for any of the following purposes with respect to the Notes:

    

    

    (1)          to evidence the
        succession of another Person to the Issuer or to a Guarantor and the assumption by any such successor of the covenants of the Issuer or such Guarantor, as the case may be, in this Indenture and the Notes or the Note Guarantee, as applicable;

    

    

    (2)          to add to the
        covenants of the Issuer for the benefit of the Holders, or to surrender any right or power herein conferred upon the Issuer;

    

    

    (3)          to add additional
        Events of Default;

    

    

    (4)          to provide for
        uncertificated Notes in addition to or in place of the certificated Notes;

    

    

    (5)          to evidence and
        provide for the acceptance of appointment under this Indenture by a successor Trustee;

    

    

    (6)          to provide for or
        confirm the issuance of additional debt securities in accordance with the terms of this Indenture;

    

    

    (7)          to add a Guarantor or
        to release a Guarantor in accordance with this Indenture;

    

    

    (8)          to cure any
        ambiguity, defect, omission, mistake or inconsistency;

    

    

    (9)          to make any other
        provisions with respect to matters or questions arising under this Indenture; provided, however, that such actions pursuant to this clause (9) shall not adversely affect the interests of the Holders of the Notes in any material respect, as
        determined in good faith by the Board of Directors of the Issuer;

    

    

    (10)          to conform the text
        of this Indenture or the Notes to any provision of the “Description of Notes” in the Offering Memorandum to the extent that the Trustee has received an Officers’ Certificate stating that such text constitutes an unintended conflict with the
        description of the corresponding provision in said “Description of Notes”;

    

    

    (11)          to effect or
        maintain the qualification of this Indenture under the TIA; or

    

    

    
      36

      
        


    

    

    

    (12)          to comply with the
        rules of any applicable securities depository.

    

    

    Subject to Section 9.2, and upon receipt by the Trustee of the documents
      described in Sections 9.5 and 12.2, the Trustee will join with the Issuer and the Guarantors,
      if applicable, in the execution of such amendment or supplement unless such amendment or supplement directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion,
      but will not be obligated to, enter into such amendment or supplement.

    

    

    After an amendment or supplement under this Section 9.1 becomes effective,
      the Issuer shall mail to Holders a notice briefly describing such amendment or supplement.  The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment or supplement under this Section 9.1.

    

    

    SECTION 9.2.          With Consent of Holders.  With the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes, the Issuer and the Trustee may enter into an indenture or
        indentures supplemental to this Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture applicable to the Notes or the Note Guarantees or of the Notes or of any Note
        Guarantee or of modifying in any manner the rights of the Holders under this Indenture, including the definitions therein, in each case with respect to the Notes; provided,
        however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Note affected thereby:

    

    

    (1)          change the Stated
        Maturity of any Note or of any installment of interest on any Note, or reduce the amount payable in respect of the principal thereof or the rate of interest thereon or any premium payable thereon, or reduce the amount that would be due and payable
        on acceleration of the maturity thereof, or change the place of payment where, or the coin or currency in which, any Note or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment
        on or after the Stated Maturity thereof, or change the date on which any Notes may be subject to redemption or reduce the redemption price therefor;

    

    

    (2)          reduce the percentage
        in aggregate principal amount of the outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this
        Indenture or certain defaults thereunder and their consequences) provided for in this Indenture;

    

    

    (3)          modify the
        obligations of the Issuer to make offers to purchase upon a Change of Control Repurchase Event if such modification was done after the occurrence of the related Change of Control;

     

      

    (4)          modify or change any
        provision of this Indenture affecting the ranking of the Notes in a manner adverse to the Holders of the Notes; or

    

    

    (5)          modify any of the
        provisions of this paragraph or provisions relating to waiver of defaults or certain covenants, except to increase any such percentage required for such actions or to provide that certain other provisions of this Indenture cannot be modified or
        waived without the consent of the Holder of each outstanding Note affected thereby.

    

    

    The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed amendment, supplement or waiver of this
      Indenture. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver.  A consent to any amendment, supplement or waiver under this Indenture by any Holder of Notes given in connection with a tender of
      such Holder’s Notes will not be rendered invalid by such tender.

    

    

    After an amendment or supplement under this Section 9.2 becomes effective,
      the Issuer shall mail to Holders a notice briefly describing such amendment or supplement.  The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment or supplement.

    

    

    SECTION 9.3.          Revocation and Effect of Consents and Waivers.  Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and
        every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s

     

      

    
      37

      
        


    

    

    

    Note, even if notation of the consent or waiver is not made on any Note.  However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent or waiver
      as to such Holder’s Note or portion of its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective.  An amendment, supplement or waiver becomes effective in accordance with its
      terms and thereafter binds every Holder.

    

    

    The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any
      other action described in this Section 9.3 or required or permitted to be taken pursuant to this Indenture.  If a record date is fixed, then notwithstanding the immediately
      preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether
      or not such Persons continue to be Holders after such record date.  No such consent shall be valid or effective for more than 120 days after such record date.

    

    

    SECTION 9.4.          Notation on or Exchange of Notes.  The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated.  The Issuer in exchange for all Notes
        may issue and the Trustee shall, upon receipt of an Issuer Order, authenticate new Notes that reflect the amendment, supplement or waiver.  Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such
        amendment, supplement or waiver.

    

    

    SECTION 9.5.          Trustee to Sign Amendments.  The Trustee shall sign any amendment or supplement to this Indenture or any Note authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee.  In executing any amendment or supplemental, the Trustee shall receive and, subject to Sections 7.1 and 7.2 in the case of the Trustee, shall be fully protected in conclusively relying
        upon, in addition to the documents required by Section 12.2, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplement
        is authorized or permitted by this Indenture and is valid, binding and enforceable against the Issuer and/or any Guarantor, as the case may be, in accordance with its terms.

    

    

    ARTICLE X

    

    

    GUARANTEE

    

    

    SECTION 10.1.          Note Guarantees.

    

    

    (a)          Any Note Guarantee shall be evidenced by a supplemental
        indenture, executed by the applicable Guarantor and delivered by it to the Trustee, which shall be substantially in the form of Exhibit B.

    

    

    (b)          In connection with the execution and delivery of a
        supplemental indenture pursuant to Section 10.1(a), the applicable Guarantor shall deliver to the Trustee an Opinion of Counsel stating that:

    

    

    (1)          such Note Guarantee
        has been duly executed and authorized; and

    

    

    (2)          such Note Guarantee
        constitutes a valid, binding and enforceable obligation of such Guarantor, except insofar as enforcement thereof may be limited by bankruptcy, insolvency or similar laws (including all laws relating to fraudulent transfers) and except insofar as
        enforcement thereof is subject to general principals of equity.

    

    

    (c)          From and after the execution and delivery by a Guarantor
        of a supplemental indenture to this Indenture substantially in the form of Exhibit B, the obligations of the Issuer under the Notes and this Indenture shall be, jointly and severally, unconditionally guaranteed on a senior basis by such Guarantor. 
        Subject to the provisions of this Article X, each Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly
        and severally with each other Guarantor, to each Holder of the Notes and the Trustee and their respective successors and assigns, the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the
        principal of, premium, if any, and interest, if any, on the Notes and all other obligations and liabilities of the Issuer under the Indenture and the Notes (including without limitation, interest, if any, accruing after the filing of any petition
        in bankruptcy, or the commencement of any

     

      

    
      38

      
        


    

    

    

    insolvency, reorganization or like proceeding, relating to the Issuer or any Guarantor whether or not a claim for post‐filing or post‐petition interest is allowed in such
      proceeding and the obligations under Section 7.7) (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).  Each Guarantor agrees that the Guaranteed Obligations will rank equally in right of payment with other indebtedness of such Guarantor, except to the extent such other indebtedness is subordinate to
      the Guaranteed Obligations, in which case the obligations of the Guarantors under the Note Guarantees will rank senior in right of payment to such other indebtedness.

    

    

    Each Guarantor hereby agrees that its Note Guarantee set forth in this Section 10.1
      shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

    

    

    If an Officer whose signature is on the applicable supplemental indenture to this Indenture no longer holds that office at the time the Trustee
      authenticates the Note, the Note Guarantee shall be valid nevertheless.

    

    

    Each Guarantor further agrees (to the extent permitted by law) that the Guaranteed Obligations may be extended or renewed, in whole or in part, without
      notice or further assent from it, and that it will remain bound under this Article X notwithstanding any extension or renewal of any Guaranteed Obligation.

    

    

    Each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives notice of
      protest for nonpayment.  Each Guarantor waives notice of any default under the Notes or the Guaranteed Obligations.

    

    

    Each Guarantor further agrees that its Note Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection) and waives
      any right to require that any resort be had by any Holder to any security held for payment of the Guaranteed Obligations.

    

    

    Except as set forth in Section 10.2, the obligations of each Guarantor
      hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guaranteed Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall
      not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.  Without limiting the generality of the foregoing,
      the Guaranteed Obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of the Trustee or any Holder to assert any claim or demand or to enforce any right or remedy against the Issuer or any
      other person under this Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any
      other agreement; (d) the failure of any Holder to exercise any right or remedy against any other Guarantor; (e) any change in the ownership of the Trustee or Issuer; (f) any default, failure or delay, willful or otherwise, in the performance of the
      Guaranteed Obligations; or (g) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of such Guarantor as a
      matter of law or equity.

    

    

    Each Guarantor agrees that its Note Guarantee herein shall remain in full force and effect until payment in full of all the Guaranteed Obligations or
      such Guarantor is released from its Note Guarantee in compliance with Section 10.2, Article VIII
      or Article XI.  Each Guarantor further agrees that its Note Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or
      any part thereof, of principal of, premium, if any, or interest on any of the Guaranteed Obligations is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Issuer, any Guarantor or
      otherwise.

    

    

    In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee or has at law or in equity against any Guarantor
      by virtue hereof, upon the failure of the Issuer to pay any of the Guaranteed Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Guarantor hereby promises to and will, upon
      receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders (or the Trustee on behalf of the Holders) an amount equal to the sum of (i) the unpaid amount of such Guaranteed Obligations then due and owing and
      (ii) accrued and unpaid interest, if any, on such Guaranteed Obligations then due and owing (but only to the extent not prohibited by law) (including interest accruing after the filing of any petition in bankruptcy or the commencement of

    
      39

      
        


    

    

    

    any insolvency, reorganization or like proceeding relating to the Issuer or any Guarantor whether or not a claim for post‐filing or post‐petition interest is allowed in
      such proceeding).

    

    

    Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Guaranteed
      Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Note Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed
      Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guaranteed Obligations, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the
      purposes of this Note Guarantee.

    

    

    Each Guarantor also agrees to pay any and all fees, costs and expenses (including attorneys’ fees and expenses) incurred by the Trustee or the Holders in
      enforcing any rights under this Section 10.1.

    

    

    SECTION 10.2.          Termination, Release and Discharge; Limitation on Liability.  Any Guarantor will be automatically and unconditionally released from all obligations under its Note Guarantee, and such Note Guarantee
        shall thereupon terminate and be discharged and of no further force and effect, upon:

    

    

    (a)          receipt by the Trustee of a notification from the Issuer
        that such Note Guarantee will be released; and

    

    

    (b)          (1) any sale, exchange, disposition or transfer (by
        merger, consolidation or otherwise) of (x) any equity interests of such Guarantor following which such Guarantor is no longer a Restricted Subsidiary of the Issuer or (y) all or substantially all the properties and assets of such Guarantor to a
        Person that is not a Restricted Subsidiary of the Issuer;

    

    

    (2)          the release,
        discharge or other termination of (A) the Specified Unsecured Debt (or the guarantee of Specified Unsecured Debt issued by the Issuer or any Restricted Subsidiary by such Guarantor), including as a result of the repayment thereof which resulted in
        the creation of such Note Guarantee (or would have resulted in the creation of a Note Guarantee had such Note Guarantee not already been in existence), (B) the guarantee of the Credit Agreement by such Guarantor or (C) the guarantee of the Blue
        Cube Notes by such Guarantor, in any such case so long as immediately after the release of such Note Guarantee (and after giving effect to all other substantially simultaneous releases of any other guarantees or indebtedness by such Guarantor), the
        Issuer would be in compliance with the covenant described under Section 3.4;

    

    

    (3)          the merger or
        consolidation of such Guarantor with and into either the Issuer or any other Guarantor that is the surviving person in such merger or consolidation, or upon the liquidation of such Guarantor following the transfer of all or substantially all of its
        property and assets to either the Issuer or another Guarantor;

    

    

    (4)          the exercise by the
        Issuer of its defeasance or covenant defeasance options, or the discharge of the Issuer’s obligations under this Indenture and the Notes, as provided in Articles VIII or
        XI;

    

    

    (5)          such Guarantor no
        longer being a Restricted Subsidiary; or

    

    

    (6)          if a Note Guarantee
        is provided by Blue Cube pursuant to the second sentence of the covenant described under Section 3.4, and solely with respect to the Note Guarantee of Blue Cube, the
        release, discharge or other termination of all guarantees of the Blue Cube Notes.

    

    

    Upon any such occurrence specified above, the Trustee shall execute any documents prepared by the Issuer and reasonably required to acknowledge such
      release, discharge and termination in respect of such Note Guarantee.  Neither the Issuer nor any Guarantor shall be required to make a notation on the Notes to reflect any such Note Guarantee or any such release, termination or discharge.

    

    

    Each Guarantor, and by its acceptance of the Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of
      a Guarantor not constitute a fraudulent conveyance or fraudulent transfer under Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any

     

    

    
      40

      
        


    

    

    

    similar federal or state law to the extent applicable to any Note Guarantee.  To effectuate the foregoing intention, the Trustee and the Holders (by their acceptance of the
      Notes) hereby irrevocably agree, and the Issuer shall cause  each Guarantor to irrevocably agree, that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other
      contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the
      obligations of such other Guarantor under this Section 10.2 or Section 3.4, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law.

    

    

    SECTION 10.3.          Right of Contribution.  From and after the execution and delivery by any Guarantor of a supplemental indenture to this Indenture substantially in the form of Exhibit B, each such Guarantor agrees
        that to the extent that any Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the Note Guarantees, such Guarantor shall be entitled to seek and receive contribution from and against the Issuer
        or any other Guarantor who has not paid its proportionate share of such payment.  The provisions of this Section 10.3 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders and each Guarantor
        shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Guarantor hereunder.

    

    

    SECTION 10.4.          No Subrogation.  Notwithstanding any payment or payments made by each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against
        the Issuer or any other Guarantor or guarantee or right of offset held by the Trustee or any Holder for the payment of the Guaranteed Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Issuer
        or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Issuer on account of the Guaranteed Obligations are paid in full.  If any amount shall be paid to any
        Guarantor on account of such subrogation rights at any time when all of the Guaranteed Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds
        of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Guaranteed
        Obligations.

    SATISFACTION AND DISCHARGE

    

    

    SECTION 11.1.          Satisfaction and Discharge.  The Issuer may terminate its obligations and the obligations of each Guarantor, if any, under this Indenture with respect to the Notes and Note Guarantees when

    

    

    (a)          either:

    

    

    (1)          all Notes theretofore
        authenticated and delivered have been delivered to the Trustee for cancellation; or

    

    

    (2)          all such Notes not
        theretofore delivered to the Trustee for cancellation (i) have become due and payable or (ii) will become due and payable within one year or are to be called for redemption within one year under irrevocable arrangements satisfactory to the Trustee
        for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer, and the Issuer has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire
        indebtedness on the Notes, not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest to the Stated Maturity or date fixed for redemption;

    

    

    (b)          the Issuer has paid or caused to be paid all other sums
        then due and payable under this Indenture by the Issuer with respect to the Notes;

    

    

    (c)          the deposit will not result in a breach or violation of,
        or constitute a default under, any other instrument to which the Issuer is a party or by which the Issuer is bound;

    

    

    
      41

      
        


    

    

    

    (d)          the Issuer has delivered irrevocable instructions to the
        Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the date fixed for redemption, as the case may be; and

    

    

    (e)          the Issuer has delivered to the Trustee an Officers’
        Certificate and an Opinion of Counsel each stating that all conditions precedent under this Article XI relating to the satisfaction and discharge of this Indenture have
        been complied with.

    

    

    Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to Section 11.1(b), the provisions of Sections 11.2 and 8.6
      will survive.

    

    

    SECTION 11.2.          Application of Trust Money.  Subject to the provisions of Section 8.6, all money deposited with the Trustee pursuant to Section 11.1(b) shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any
        Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee;
        but such money need not be segregated from other funds except to the extent required by law.

    

    

    If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 11.1 by reason of any legal proceeding or by reason of any order or judgment of any court or Governmental Authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and any
      Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.1; provided that if the Issuer has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the
      Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

        Indenture or the Notes, the Issuer or such Guarantor, as the case may be, shall furnish to the Trustee:

    

    

    (1)          an Officers’
        Certificate in form satisfactory to the Trustee (which shall include the statements set forth in Section 12.3) stating that, in the opinion of the signers, all conditions
        precedent, if any, provided for in this Indenture or the Notes relating to the proposed action have been satisfied; and

    

    

    (2)          an Opinion of Counsel

        precedent have been satisfied and all covenants have been complied with;

    

    

    provided that in the case of any such application or request as to which the
      furnishing of such documents is specifically required by any provision of this Indenture relating to such particular request or application, no additional certificate or opinion need be furnished.

    

    

    SECTION 12.3.          Statements Required in Certificate or Opinion.  Each certificate or opinion with respect to compliance with a covenant or condition provided for in this Indenture or the Notes shall include:

    (4)          a statement as to
        whether or not, in the opinion of such individual, such covenant or condition has been complied with.

    SECTION 12.4.          When Notes Disregarded.  In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer, any
        Guarantor or any Affiliate of any of them shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes
        which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded.  In connection with any such direction, waiver or consent, the Issuer shall furnish to the Trustee an Officers’ Certificate listing and identifying all Notes,
        if any, known by the Issuer to be owned by or for the account of any of the above-described Persons.  Also, subject to the foregoing, only Notes outstanding at the time shall be considered in any such determination.

    

    

    SECTION 12.5.          Rules by Trustee, Paying Agent and Registrar.  The Trustee may make reasonable rules for action by, or at meetings of, Holders.  The Registrar and the Paying Agent may make reasonable rules for their
        functions.

    

    

    SECTION 12.6.          Legal Holidays.  If a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period.  If a
        regular record date is a Legal Holiday, the record date shall not be affected.

    

    

    SECTION 12.7.          Governing Law.  THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

    

    

    SECTION 12.8.          Jurisdiction.  The Issuer and the Guarantors agree that any suit, action or proceeding against the Issuer or any Guarantor brought by any Holder or the Trustee arising out of or based upon this
        Indenture, the Note Guarantee or the Notes may be instituted in any state or Federal court in the Borough of Manhattan, New York, New York, and any appellate court from any thereof, and each of them irrevocably submits to the non‐exclusive
        jurisdiction of such courts in any suit, action or proceeding.  The Issuer and the Guarantors irrevocably waive, to the fullest extent permitted by law, any objection to any suit, action, or proceeding that may be brought in connection with this
        Indenture, the Note Guarantee or the Notes, including such actions, suits or proceedings relating to securities laws of the United States of America or any state thereof, in such courts whether on the grounds of venue, residence or domicile or on
        the ground that any such suit, action or proceeding has been brought in an inconvenient forum.  The Issuer and the Guarantors agree that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding
        upon the Issuer or the Guarantors, as the case may be, and may be enforced in any court to the jurisdiction of which the Issuer or the Guarantors, as the case may be, are subject by a suit upon such judgment.

    

    

    SECTION 12.9.          Waivers of Jury Trial.  EACH OF THE ISSUER, THE GUARANTORS AND THE TRUSTEE HEREBY IRREVOCABLY AND
          UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE NOTE GUARANTEES AND FOR ANY
          COUNTERCLAIM THEREIN.

    

    

    SECTION 12.10.          USA PATRIOT Act.  The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the

     

      

    
      44

      
        


    

    

    

    funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship
      or opens an account.  The parties to this Indenture agree that they will provide the Trustee with such information as each may request in order to satisfy the requirements of the USA PATRIOT Act.

    

    

    SECTION 12.11.          No Personal Liability of Directors, Officers, Employees and Shareholders.  No past, present or future director, officer, employee, manager, partner, incorporator or shareholder of the Issuer or any
        of its Subsidiaries or Affiliates, as such (other than the Issuer), shall have any liability for any obligations of the Issuer or any Guarantor under this Indenture or the Notes or for any claim based on, in respect of, or by reason of, such
        obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

    

    

    SECTION 12.12.          Successors.  All agreements of the Issuer and each Guarantor in this Indenture and the Notes shall bind their respective successors.  All agreements of the Trustee in this Indenture shall bind its
        successors.

    

    

    SECTION 12.13.          Multiple Originals.  The parties may sign any number of copies of this Indenture.  Each signed copy shall be an original, but all of them together represent the same agreement.  The exchange of
        copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. 
        Signatures of the parties hereto transmitted by facsimile or other electronic transmission shall be deemed to be their original signatures for all purposes.

    

    

    SECTION 12.14.          Table of Contents; Headings.  The table of contents and headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not intended to be considered
        a part hereof and shall not modify or restrict any of the terms or provisions hereof.

    

    

    SECTION 12.15.          Force Majeure.  In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly,
        forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of
        utilities, communications or computer (software and hardware) services, it being understood that the Trustee shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as
        practicable under the circumstances.

    

    

    SECTION 12.16.          Severability.  In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in
        any way be affected or impaired thereby.

      shall pay interest on overdue principal at the rate specified herein, and it shall pay interest (including post‐petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace
      period) at the same rate to the extent lawful.  Interest on the Notes will be computed on the basis of a 360‐day year comprised of twelve 30‐day months.  Each interest period will end on (but not include) the relevant Interest Payment Date.

    

    

    2.           Method of Payment

    

    

    By no later than noon (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Issuer
      shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium and interest when due.  Interest on any Note which is payable, and is timely paid or duly provided for, on any Interest Payment Date
      shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the preceding May 15 or November 15, as applicable, at the office or agency of the Issuer maintained for such purpose
      pursuant to Section 2.3 of the Indenture.  The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of Paying Agent or
      Registrar designated by the Issuer maintained for such purpose (which shall initially be the office of the Trustee maintained for such purpose), or at such other office or agency of the Issuer as may be maintained for such purpose pursuant to Section 2.3 of the Indenture; provided, however, that, at the option of the Paying Agent, each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Notes
      Register or (ii) wire transfer to an account located in the United States maintained by the payee, subject to the last sentence of this paragraph.  Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and
      interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depository.  Payments in respect of Notes represented by Definitive Notes (including principal, premium,
      if any, and interest) held by a Holder of at least $1,000,000 aggregate principal amount of Notes represented by Definitive Notes will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such
      Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than fifteen (15) days immediately preceding the relevant due date for payment (or such other date as
      the Trustee may accept in its discretion).  If an Interest Payment Date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period.  If a regular record
      date is a Legal Holiday, the record date shall not be affected.

      as Registrar and Paying Agent for the Notes.  The Issuer may change any Registrar or Paying Agent without prior notice to the Holders.  The Issuer or any Guarantor may act as Paying Agent, Registrar or transfer agent.

    

    

    4.           Indenture

    

    

    The Issuer issued the Notes under an Indenture dated as of May 19, 2020 (as it may be amended or supplemented from time to time in accordance with the
      terms thereof, the “Indenture”), between the Issuer and the Trustee.  The terms of the Notes include those stated in the Indenture and those specific provisions of the Trust
      Indenture Act of 1939 (15 U.S.C. Sections 77aaa‐77bbbb) (the “Act”) expressly referenced in the provisions of the Indenture. The Act shall not otherwise be applicable to, or
      govern, the Indenture or the Notes.  The Notes are subject to all terms and provisions of the Indenture, and Holders are referred to the Indenture and the Act for a statement of those terms.

    

    

    6.           Optional Redemption

    

    

    (a)          At any time prior to the Par Call Date, the Issuer may redeem the Notes at its option, in whole at any time or in part from time to time prior to the Par Call Date, upon notice as described under Section 5.2 of the
        Indenture, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any,
          to, but excluding, the date of redemption (the “Redemption Date”),
          subject to the rights of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

    

    

    (b)          At any time on or after the Par Call Date, the Issuer may redeem the Notes at its option, in whole at any time or in part from time to time on or after the Par Call Date, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date, subject to the rights of the Holders of
          record on the relevant record date to receive interest due on the relevant interest payment date.

    

    

    (e)          Notice of any redemption may, at the Issuer’s
        discretion, be subject to one or more conditions precedent.

    

    

    (f)          If the optional redemption date is on or after a record
        date and on or before the related interest payment date, the accrued and unpaid interest will be paid to the Person in whose name the Note is registered at the close of business on such record date, and no additional interest will be payable to
        Holders whose Notes will be subject to redemption by the Issuer.

    

    

    (g)          Unless (i) the Issuer defaults in the payment of the
        redemption price or (ii) such redemption remains conditioned on the happening of a future event, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

    

    

    (h)          Any redemption pursuant to this paragraph 6 shall be
        made pursuant to the provisions of Sections 5.1 through 5.5 of the Indenture.

    

    

    The Issuer is not required to make mandatory redemptions or sinking fund payments with respect to the Notes; provided, however, that under certain circumstances, the Issuer may be required to offer to purchase Notes
      under Section 3.5 of the Indenture.  The Issuer may at any time and from time to time purchase Notes in the open market or otherwise.

    

    

    7.           Repurchase Provisions

    

    

    If a Change of Control Repurchase Event occurs, unless the Issuer has exercised its right to redeem the Notes as provided in the Indenture, the Issuer
      shall make an offer to each Holder of Notes to repurchase all or any part (in integral multiples of $1,000 principal amount) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased
      plus any accrued and unpaid interest on the Notes

    
      A-5

      excess thereof.  A Holder may transfer or exchange Notes in accordance with the Indenture.  The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any tax
      and fees required by law or permitted by the Indenture.  The Registrar need not register the transfer of or exchange of any Note (A) for a period beginning (1) fifteen (15) days before the mailing of a notice of an offer to repurchase or redeem Notes
      and ending at the close of business on the day of such mailing or (2) fifteen (15) days before an Interest Payment Date and ending on such Interest Payment Date or (B) called for redemption, except the unredeemed portion of any Note being redeemed in
      part.

    

    

    9.           Persons Deemed Owners

    Subject to certain exceptions and conditions set forth in the Indenture, the Issuer at any time may terminate some or all of its obligations under the
      Notes and the Indenture if the Issuer deposits with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Notes to redemption or maturity, as the case may be.

    

    

    12.          Amendment, Supplement, Waiver

    

    

    Subject to certain exceptions contained in the Indenture, the Indenture may be amended, or a Default thereunder may be waived, with the consent of the
      Holders of a majority in aggregate principal amount of the outstanding Notes (including consents obtained in connection with a purchase, or tender offer or exchange offer for, such Notes).  Without notice to or the consent of any Holder, the Issuer
      and the Trustee may amend or supplement the Indenture as provided therein.

    

    

    13.          Defaults and Remedies

    

    

    Except as provided otherwise in the Indenture, if an Event of Default (other than an Event of Default relating to certain events of bankruptcy,
      insolvency or reorganization of the Issuer) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any
      accrued and unpaid interest on the Notes to be due and payable immediately by a notice in writing to the Issuer (and to the Trustee if given by Holders); provided,
      however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the
      outstanding Notes may rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of or interest on the Notes, have been cured or waived as provided in the Indenture.

    

    

    14.          Trustee Dealings with the Issuer

    

    

    Subject to certain limitations set forth in the Indenture, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes
      and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee.  In addition, the Trustee shall be permitted to engage in transactions with the Issuer; provided, however, that if the Trustee acquires any “conflicting interest” (as defined in the TIA), the Trustee
      must (i) eliminate such conflict within 90 days of acquiring such conflicting interest or (ii) resign.

    9.500% Senior Notes due 2025 (the “Notes”)

    

    

    Ladies and Gentlemen:

    

    

    In connection with our proposed sale of $[________] aggregate principal amount of the Notes, we confirm that such sale has been effected pursuant to and
      in accordance with Regulation S under the United States Securities Act of 1933, as amended (the “Securities Act”), and, accordingly, we represent that:

    

    

    (a)          the offer of the Notes was not made
        to a person in the United States;

    

    

    (b)          either (i) at the time the buy order
        was originated, the transferee was outside the United States or we and any person acting on our behalf reasonably believed that the transferee was outside the United States or (ii) the transaction was executed in, on or through the facilities of a
        designated off‐shore securities market and neither we nor any person acting on our behalf knows that the transaction has been pre‐arranged with a buyer in the United States;

    

    

    (c)          no directed selling efforts have been
        made in the United States in contravention of the requirements of Rule 903(a)(2) or Rule 904(a)(2) of Regulation S, as applicable; and

    

    

    (d)          the transaction is not part of a plan
        or scheme to evade the registration requirements of the Securities Act.

    

    

    In addition, if the sale is made during a restricted period and the provisions of Rule 903(b)(2), Rule 903(b)(3) or Rule 904(b)(1) of Regulation S are
      applicable thereto, we confirm that such sale has been made in accordance with the applicable provisions of Rule 903(b)(2), Rule 903(b)(3) or Rule 904(b)(1), as the case may be.

    

    

    We also hereby certify that we [are][are not] an Affiliate of the Issuer and, to our knowledge, the transferee of the Notes [is][is not] an Affiliate of
      the Issuer.

    

    

    The Trustee, Registrar and the Issuer are entitled to conclusively rely upon this letter and are irrevocably authorized to produce this letter or a copy
      hereof to any interested party in any administrative or legal proceedings or
