      and pursuant to authorization by, DTC shall be deemed to constitute the “Act” of the Holder of such Global Security, and such Act shall be deemed to have been delivered to the Issuers and the Trustee upon the delivery by DTC of an “agent’s



        message” or other notice of such consent or other action having been so given, made or taken in accordance with the Applicable Procedures of DTC.

      writing may be proved by any reasonable method including the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing
      such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.
      In addition, the fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

   

  The ownership of Securities shall be proved by the Security Register.

  With respect to Securities of any series, the Issuers may set any day as a
      record date for the purpose of determining the Holders of Outstanding Securities of such series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this
      Indenture to be given, made or taken by Holders of Securities of such series, provided that the Issuers may set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving, making or taking of any notice,
      declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to
      give, make or take the relevant action, whether or not such Holders remain Holders after such record date; provided, however, that no such action shall be effective hereunder unless given, made or taken on or prior to the applicable
      Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent an Issuer from setting a new record date for any action for which a
      record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render
      ineffective any action given, made or taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is given, made or taken. Promptly after any record date is set pursuant to this
      paragraph, the Issuers, at their own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in

  The Trustee may set any day as a record date for the purpose of
      determining the Holders of Outstanding Securities of any series entitled to join in the giving, making or taking of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute
      proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding
      Securities of such series on such record date, and no other Holders, shall be entitled to give, make or take such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided, however,
      that no such action shall be effective hereunder unless given, made or taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this
      paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no
      action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action given, made or taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series
      on the date such action is given, made or taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Issuers’ expense, shall cause notice of such record date, the proposed action by Holders and the applicable
      Expiration Date to be given to the Issuers in writing and to each Holder of Securities of the relevant series in the manner set forth in Sections 105 and 106.

   

  With respect to any record date set pursuant to this Section 104,
      the party hereto which sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless
      notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an
      Expiration Date is not designated with respect to any record date set pursuant to this Section 104, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the
      Expiration Date with respect thereto, subject to its right to change the Expiration Date to an earlier day as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record
      date.

   

  Without limiting the foregoing, a Holder entitled hereunder to give, make
      or take any action hereunder with regard to any particular Security may do so, in person or by an agent duly appointed in writing, with regard to all or any part of the principal amount of such Security.

   

  SECTION 105.          Notices, Etc., to Trustee, Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made

      (ii) upon confirmation of delivery, if mailed by first class mail (registered or certified, return receipt requested), if mailed; (iii) the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next

  The Trustee shall have the right to accept and act upon any notice,
      instruction, or other communication from the Issuers, including any funds transfer instruction (each, a “Notice”), received pursuant to this Indenture by electronic transmission (including by e-mail, web portal or other electronic methods) and
      reasonably believed by the Trustee to be valid and the Trustee shall not have any duty to confirm that the person sending such Notice is, in fact, a person authorized to do so, and furthermore (i) the Trustee shall not have any liability for any
      losses, liabilities, costs or expenses incurred or sustained directly or indirectly by any party as a result of such reliance upon or compliance with such instructions, directions, reports, notices or other communications or information and (ii) the
      Issuers and any other sending party agrees to assume all risks arising out of the use of electronic methods to submit instructions, directions, reports, notices or other communications or information to the Trustee, including the risk of the Trustee
      acting on unauthorized instructions, notices, reports or other communications or information, and the risk of interception and misuse by third parties.

      the ESIGN Act of 2000 or other applicable law (including electronic images of handwritten signatures and digital signatures provided by DocuSign, Adobe Sign or any other digital signature provider identified by any other party hereto and acceptable
      to the Trustee) shall be deemed original signatures for all purposes. Notwithstanding the foregoing, the Trustee may require that a Notice in the form of an original document bearing a manual signature be delivered to the Trustee in lieu of, or in
      addition to, any such electronic Notice.

   

  Notwithstanding anything to the contrary in this Indenture or the
      Securities, any notice to the Trustee shall be deemed given when actually received.

   

  Notwithstanding anything to the contrary in this Indenture or the
      Securities, (A) whenever any provision of this Indenture requires a party to send notice to another party, no such notice need be sent if the sending party and the recipient are the same Person acting in different capacities, and (B) whenever any
      provision of this Indenture requires a party to send notice to more than one receiving party, and each receiving party is the same Person acting in different capacities, then only one such notice need be sent to the Person.

   

  SECTION 106.          Notice to Holders; Waiver. Where this Indenture provides for notice or other communication to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly
      provided) if given in writing and mailed by first class mail (registered or certified, return receipt requested) or sent by overnight air courier guaranteeing next Business Day delivery, to each Holder affected by such event, at such Holder’s address
      as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice or other communication. Any notice or other communication shall also be so
      mailed or sent to any Person described in Section 313(c) of the Trust Indenture Act, to the extent required by the Trust Indenture Act. Failure to mail or send a notice or other communication to a Holder or any defect in it shall not affect its
      sufficiency with respect to other Holders.

   

  If a notice or communication is mailed or sent in the manner provided
      above within the time prescribed, it is duly given, whether or not the addressee receives it. Where this Indenture provides for notice or other communication in any manner, such notice or other communication may be waived in writing by the Person
      entitled to receive such notice or other communication, either before or after the event, and such waiver shall be the equivalent of such notice or other communication. Waivers of notice or other communication by Holders shall be filed with the
      Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. If an Issuer mails a notice or communication to the Holders, it shall mail a copy to the Trustee at the same time.

   

  In case by reason of the suspension of regular mail service or by reason
      of any other cause it shall be impracticable to give such notice or other communication by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

   

  Notwithstanding anything to the contrary in this Indenture or the
      Securities, where this Indenture provides for notice or other communication with respect to any event to a Holder of a Global Security, such notice or other communication shall be sufficiently given if given to the Depositary for such Security (or
      its designee), pursuant to its Applicable Procedures. The Trustee will not have any liability relating to the contents of any notice that it sends to any Holder pursuant to any Company Order or Company Request.

  SECTION 107.          Trust Indenture Act Matters. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this
      Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as

      to credit or cause to be credited a beneficial interest in another Global Security in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing
      information regarding the Participant account to be credited with such increase. Upon consummation of an Exchange Offer by the Issuers in accordance with Section 205(3), the requirements of this Section 205(1)(B) shall be deemed to

      Securities contained in this Indenture and the Securities or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Securities pursuant to Section 205(6).

  (C) Transfer of Beneficial Interests to Another Restricted Global Security. A beneficial interest in any Restricted Global Security may be transferred to a Person who takes delivery thereof in the form of a
      beneficial interest in another Restricted Global Security if the transfer complies with the requirements of Section 205(1)(A) above and the Securities Registrar receives the following:

   

  (i) if the transferee shall take delivery in the form of a beneficial interest in the 144A Global Security, then the transferor must deliver a certificate in a form reasonably acceptable to the Securities

  (3) Exchange Offer. Upon the occurrence of an Exchange Offer in accordance with the applicable Registration Rights Agreement, the Issuers shall issue and, upon receipt of a Company Order in accordance with
      Section 303, the Trustee shall authenticate (i) one or more Unrestricted Global Securities in an aggregate principal amount equal to the principal amount of the beneficial interests in the Restricted Global Securities tendered for acceptance

  THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES
      ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), 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 IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE
      HOLDER (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER
      THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT, PRIORTO THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE SECURITIES UNDER RULE 144 UNDER THE SECURITIES ACT AS IN EFFECT ON THE DATE OF THE TRANSFER OF THIS SECURITY, OFFER, RESELL,
      PLEDGE OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO AN ISSUER OR ANY SUBSIDIARY THEREOF, (B) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT, TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE
      WITH RULE 144A UNDER THE SECURITIES ACT; (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT
      (IF AVAILABLE), (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (F) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON
      TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN THE TIME PERIOD REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE
      HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE. 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.
      THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF A HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE.

  
    21 

    
      
 

  

   

  Notwithstanding the foregoing, any Global Security or
      definitive Security issued pursuant to Clauses (1)(D), (2)(B), (2)(C) or (3) to this Section 205 (and all Securities issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

   

  (5) Regulation S Global Security Legend. Each Regulation S Global Security shall bear a legend in substantially the following form:

   

  THE RIGHTS ATTACHING TO THIS REGULATION S GLOBAL SECURITY, AND THE
      CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR OTHER SECURITIES OF THIS SERIES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN).

   

  (6) Cancellation and/or Adjustment of Global Securities. At such time as all beneficial interests in a particular Global Security have been exchanged for definitive Securities or a particular Global
      Security has been redeemed, repurchased or canceled in whole and not in part, each such Global Security shall be returned to or retained and canceled by the Trustee in accordance with Section 309 hereof. At any time prior to such
      cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Security or for definitive Securities, the principal
      amount of Securities represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the
      beneficial interest is being exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Security, such other Global Security shall be increased accordingly and an endorsement shall
      be made on such Global Security by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

   

  (7) 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 Depositary participants, members or beneficial owners in any Global Security) 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.

      Applicable Procedures in with respect to any Global Security.

   

  SECTION 302.          Denominations. The Securities of each series shall be issuable only in registered form without coupons and only in such denominations as shall be specified as contemplated by Section 301.

  SECTION 303.          Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Issuers by their respective Chairman of the Board, President or Chief Executive Officer, Chief
      Financial Officer, or a Vice President of each Issuer (or any other officer of the Issuers designated in a Board Resolution and delivered to the Trustee from time to time). The signature of any of these officers on the Securities may be in accordance
      with Section 106 and 1306.

   

  [if applicable, insert — Securities bearing the signatures of
      individuals who were at any time the proper officers of the Issuers shall bind the Issuers notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not
      hold such offices at the date of such Securities.]

   

  At any time and from time to time after the execution and delivery of this
      Indenture, the Issuers may deliver Securities of any series executed by the Issuers, to the Trustee for authentication, together with a Company Order, and the Trustee in accordance with the Company Order shall authenticate and deliver such
      Securities. The Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,

   

  (1) if the form of such Securities has been established by or pursuant to Board Resolution, as permitted by Section 201, that such form has been established in conformity with the provisions of this
      Indenture;

   

  (2) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of this
      Indenture; and

   

  (3) for any issuance of Securities, that when such Securities have been authenticated and delivered by the Trustee and issued by the Issuers in the manner and subject to any conditions specified in such Opinion
      of Counsel, such Securities will constitute valid and legally binding obligations of the Issuers, enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent conveyance or transfer, reorganization, moratorium and similar
      laws of general applicability relating to or affecting creditors’ rights and to general equity principles and subject to any limitation with respect to payments in currency other than U.S. dollars.

   

  The Trustee shall not be required to authenticate Securities if the issue
      of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

  
    25 

    
      
 

  

   

  Notwithstanding the provisions of Section 301 and of the preceding
      paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order, and Opinion of Counsel
      otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to
      be issued and cover subsequent issuances of Securities.

   

  Each Security shall be dated the date of its authentication.

   

  No Security shall be entitled to any benefit under this Indenture or be
      valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee, and such certificate upon any Security shall be conclusive evidence, and
      the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Issuers, and the Issuers
      shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to
      the benefits of this Indenture.

   

  SECTION 304.          Temporary Securities. Pending the preparation of definitive Securities of any series, the Issuers may execute, and upon Company Order, the Trustee shall authenticate and deliver, temporary
      Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate
      insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities.

   

  If temporary Securities of any series are issued, the Issuers will cause
      definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon
      surrender of the temporary Securities of such series at the office or agency of the Issuers in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series,
      the Issuers shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged,
      the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor.

   

  SECTION 305.          Registration, Registration of Transfer and Exchange. The Issuers shall cause to be kept at each office or agency of the Issuers designated as a Place of Payment pursuant to the first paragraph of
      Section 1002 a register (the register, maintained in each such office or agency of the Issuers designated as a Place of Payment, being herein sometimes collectively referred to as the “Security Register”) in which, subject to
      such reasonable regulations as it may prescribe, the Issuers shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities
      and transfers of Securities as herein provided. The Issuers shall cause each of the Security Registrar and the Paying Agent to maintain an office or agency in the Borough of Manhattan, The City of New York.

   

  Upon surrender for registration of transfer of any Security of a series at
      the office or agency of the Issuers in a Place of Payment for that series, the Issuers shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same
      series, of any authorized denominations and of like tenor and aggregate principal amount.

   

  At the option of the Holder, Securities of any series may be exchanged for
      other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange,
      the Issuers shall execute, and the Trustee shall authenticate and deliver, the Securities, which the Holder making the exchange is entitled to receive.

   

  All Securities issued upon any registration of transfer or exchange of
      Securities shall be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

  
    26 

    
      
 

  

   

  Every Security presented or surrendered for registration of transfer or
      for exchange shall (if so required by the Issuers or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Issuers and the Security Registrar duly executed, by the Holder thereof or his
      attorney duly authorized in writing.

   

  No service charge shall be made for any registration of transfer or
      exchange of Securities, but the Issuers may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant
      to Section 304, 906 or 1107 not involving any transfer.

   

  If the Securities of any series (or of any series and specified tenor) are
      to be redeemed in whole or in part, the Issuers shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the
      opening of business 15 days before the day of selection of any such Securities for redemption under Section 1103 and ending at the close of business on the day of such selection (or during such period as otherwise specified pursuant to Section



        301 for such Securities), or (B) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

   

  The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
      Global Securities:

   

  (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee
      thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

   

  (2) Notwithstanding any other provision in this Indenture, and subject to such applicable provisions, if any, as may be specified as contemplated by Section 301, no Global Security may be exchanged in
      whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary has
      notified the Issuers that it (i) is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, or (B) the Issuers have executed and delivered to the Trustee a
      Company Order stating that such Global Security shall be exchanged in whole for Securities that are not Global Securities (in which case such exchange shall promptly be effected by the Trustee). If an Issuer receives a notice of the kind specified in
      Clause (A) above or has delivered a Company Order of the kind specified in Clause (B) above, it may, in its sole discretion, designate a successor Depositary for such Global Security within 90 days after receiving such notice or delivery of such
      order, as the case may be. If the Issuers designate a successor Depositary as aforesaid, such Global Security shall promptly be exchanged in whole for one or more other Global Securities registered in the name of the successor Depositary, whereupon
      such designated successor shall be the Depositary for such successor Global Security or Global Securities and the provisions of Clauses (1), (2), (3) and (4) of this provision shall continue to apply thereto.

   

  (3) Subject to Clause (2) above and to such applicable provisions, if any, as may be specified as contemplated by Section 301, any exchange of a Global Security for other Securities may be made in whole
      or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

   

  (4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section 305, Section



        304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such
      Global Security or a nominee thereof.

   

  Every Person who takes or holds any beneficial interest in a Global
      Security agrees that:

   

  (1) the Issuers and the Trustee may deal with the Depositary as sole owner of the Global Security and as the authorized representative of such Person;

  
    27 

    
      
 

  

   

  (2) such Person’s rights in the Global Security shall be exercised only through the Depositary and shall be limited to those established by law and agreement between such Person and the Depositary and/or direct
      and indirect participants of the Depositary;

   

  (3) the Depositary and its participants make book-entry transfers of beneficial ownership among, and receive and transmit distributions of principal and interest on the Global Securities to, such Persons in
      accordance with the Applicable Procedures of the Depositary; and

   

  (4) none of the Issuers, the Trustee nor any agent of the Issuers or the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial
      ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

   

  SECTION 306.          Mutilated, Destroyed, Lost and Wrongfully Taken Securities. If (a) any mutilated Security is surrendered to the Trustee or (b) both (i) there shall be delivered to the Issuers and the Trustee (A)
      a claim by a Holder as to the destruction, loss or wrongful taking of any Security of such Holder and a request thereby for a new replacement Security of the same series, and (B) such indemnity bond as may be required by them to save each of them and
      any agent of either of them harmless and (ii) such other reasonable requirements as may be imposed by the Issuers as permitted by Section 8-405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to the Issuers or the
      Trustee that such Security has been acquired by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code, the Issuers shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such
      mutilated, destroyed, lost or wrongfully taken Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously Outstanding.

   

  In case any such mutilated, destroyed, lost or wrongfully taken Security
      has become or is about to become due and payable, the Issuers in their discretion may, instead of issuing a new Security, pay such Security.

   

  Upon the issuance of any new Security under this Section 306, the
      Issuers may require the payment of 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 the Trustee) connected therewith.

   

  Every new Security of any series issued pursuant to this Section 306
      in lieu of any destroyed, lost or wrongfully taken Security shall constitute an original additional contractual obligation of the Issuers, whether or not the destroyed, lost or wrongfully taken Security shall be at any time enforceable by anyone, and
      shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

   

  The provisions of this Section 306 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 wrongfully taken Securities.

   

  SECTION 307.          Payment of Interest; Interest Rights Preserved. Except as otherwise provided as contemplated by Section 301 with respect to any Securities of a series, interest on any Security 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 that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for
      such interest (or, if no business is conducted by the Trustee at its Corporate Trust Office on such date, at 5:00 P.M. New York City time on such date).

   

  Any interest on any Security of any series which is payable, but is not
      punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such
      Defaulted Interest may be paid by the Issuers, at its election in each case, as provided in Clause (1) or (2) below:

   

  (1) The Issuers may elect to make payment of any Defaulted Interest payable on any Securities of a series to the Persons in whose names such Securities (or their respective Predecessor Securities) are registered
      at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuers shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on
      each of such Securities and the date of the proposed payment, and at the same time the Issuers 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 in this Clause provided.
      Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by
      the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuers of such Special Record Date and, in the name and at the expense of the Issuers, shall cause notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor to be given to each Holder of such Securities in the manner set forth in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the
      Special Record Date therefor having been so mailed or sent, such Defaulted Interest shall be paid to the Persons in whose names such Securities (or their respective Predecessor Securities) are registered at the close of business on such Special
      Record Date and shall no longer be payable pursuant to the following Clause (2). Before the Trustee takes any action under this Section 307, the Issuers will deliver to Trustee a Company Order.

  
    28 

    
      
 

  

   

  (2) The Issuers may make payment of any Defaulted Interest on any Securities of a series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may
      be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuers to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

   

  The Trustee shall not at any time be under any duty or responsibility to
      the Holders to determine the defaulted interest, or with respect to the nature, extent, or calculation of the amount of defaulted interest owed, or with respect to the method employed in such calculation of the defaulted interest.

   

  Except as may otherwise be provided in this Section 307 or as
      contemplated in Section 301 with respect to any Securities of a series, the Person to whom interest shall be payable on any Security that first becomes payable on a day that is not an Interest Payment Date shall be the Holder of such Security
      on the day such interest is paid.

   

  Subject to the foregoing provisions of this Section 307, each
      Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

   

  In the case of any Security which is converted after any Regular Record
      Date and on or prior to the next succeeding Interest Payment Date (other than any Security whose Maturity is prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest
      Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of
      business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security which is converted, interest whose Stated Maturity is after the date of conversion of such Security shall
      not be payable.

   

  Notwithstanding the foregoing, the terms of any Security that may be
      converted may provide that the provisions of the immediately preceding paragraph do not apply, or apply with such additions, changes or omissions as may be provided thereby, to such Security.

   

  SECTION 308.          Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Issuers and the Trustee and any agent of the Issuers or the Trustee shall treat the Person in whose
      name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 307) any interest on such Security and for all other purposes whatsoever, whether or
      not such Security be overdue, and none of the Issuers, the Trustee or any agent of the Issuers or the Trustee shall be affected by notice to the contrary.

  
    29 

    
      
 

  

   

  SECTION 309.          Cancellation. All Securities surrendered for payment, redemption, registration of transfer or exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any
      Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Issuers may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the any Issuer
      may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which no Issuer has issued and sold, and all Securities
      so delivered shall be promptly cancelled by the Trustee after receipt of Company Order. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 309, except as expressly permitted
      by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order and in accordance with Trustee’s customary cancellation procedures; provided, however, that the Trustee shall not be
      required to destroy such cancelled Securities.

   

  SECTION 310.          Computation of Interest. Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the
      basis of a 360-day year of twelve 30-day months.

   

  SECTION 311.          CUSIP Numbers. The Issuers, in issuing the Securities may use “CUSIP” and “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in notices of
      redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance
      may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers shall promptly notify the Trustee of any change in “CUSIP” or
      “ISIN” numbers.

   

  ARTICLE IV

      SATISFACTION AND DISCHARGE

   

  SECTION 401.          Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request cease to be of further effect with respect to the Securities of any series (except as to any surviving rights of

      and (ii) Securities for the payment of which money has theretofore been deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from such trust, as provided in Section 1003) have
      been delivered to the Trustee for cancellation; or

   

  (B) all such Securities not theretofore delivered to the Trustee for cancellation

   

  (i) have become due and payable, or

      be;

  SECTION 502.          Acceleration of Maturity; Rescission and Annulment. Except as may otherwise be provided pursuant to Section 301 for all or any specific Securities of any series, if an Event of Default

      Security of that series which specifies an amount to be due and payable thereon upon acceleration of the Maturity thereof, such amount as may be specified by the terms thereof), together with any accrued and unpaid interest thereon, shall
      automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable.

  Except as may otherwise be provided pursuant to Section 301 for
      all or any specific Securities of any series, at any time after such a declaration of acceleration with respect to Securities of that series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee
      as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Issuers and the Trustee, may rescind and annul such declaration and its consequences if

   

  (1) the Issuers have paid or deposited with the Trustee a sum sufficient to pay

   

  (A) all overdue interest on all Securities of that series,

   

  (B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor

      impair any right consequent thereon.

   

  SECTION 503.          Collection of Indebtedness and Suits for Enforcement by Trustee. The Issuers covenant that if

   

  (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 60 days, or

   

  (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,

   

  the Issuers will, upon demand of the Trustee, pay to it, for the benefit of the Holders of
      such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on
      any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses,
      disbursements and advances of the Trustee, its agents and counsel.

   

  If an Event of Default with respect to Securities of any series occurs and
      is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and
      enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

   

  SECTION 504.          Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Issuers or any other obligor upon the Securities, their property or their creditors, the Trustee shall be
      entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. The Trustee shall be
      authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such
      judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the
      reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607.

  
    33 

    
      
 

  

   

  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 Securities 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; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar
      committee.

   

  SECTION 505.          Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the
      possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall,
      after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been
      recovered.

   

  SECTION 506.          Application of Money Collected. Any money collected by the Trustee pursuant to this Article or distributable in respect of the Issuers’ obligations after an Event of Default shall be applied in
      the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only
      partially paid and upon surrender thereof if fully paid:

   

  FIRST: To the payment of all amounts due the Trustee under this Indenture;

   

  SECOND: To the payment of the amounts then due and unpaid for principal of
      and any premium and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for
      principal and any premium and interest, respectively; and

   

  THIRD: To the payment of the remainder, if any, to the Issuers, any
      Guarantor or to whomsoever may be lawfully entitled to receive the same as a court of competent jurisdiction may direct.

   

  SECTION 507.          Limitation on Suits. No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a
      receiver or trustee, or for any other remedy hereunder, unless

   

  (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

   

  (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in
      its own name as Trustee hereunder;

   

  (3) such Holder or Holders have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request;

   

  (4) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity has failed to institute any such proceeding; and

   

  (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;

   

  it being understood and intended that no one or more of such Holders shall have any right in
      any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or
      to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

  
    34 

    
      
 

  

   

  SECTION 508.          Unconditional Right of Holders to Receive Principal, Premium and Interest and to Convert. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right,
      which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption,
      on the Redemption Date), and, if the terms of such Security so provide, to convert such Security in accordance with its terms, and to institute suit for the enforcement of any such payment and, if applicable, any such right to convert, and such
      rights shall not be impaired without the consent of such Holder.

   

  SECTION 509.          Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or
      abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Issuers, the Trustee and the Holders shall be restored severally and
      respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

   

  SECTION 510.        Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Securities in the last paragraph of Section



        306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition
      to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any
      other appropriate right or remedy.

   

  SECTION 511.          Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right
      or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed
      expedient, by the Trustee or by the Holders, as the case may be.

   

  SECTION 512.          Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any
      proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that

   

  (1) such direction shall not be in conflict with any rule of law or with this Indenture;

   

  (2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction; and

   

  (3) subject to the provisions of Section 601, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall determine that the proceeding so directed would
      involve the Trustee in personal liability, or would be unjustly prejudicial to the Holders of Securities of such series not joining in any such direction (it being understood that the Trustee does not have an affirmative duty to ascertain whether or
      not such directions are unduly prejudicial to such Holders); and

   

  (4) prior to taking any action as directed under this Section 512, the Trustee shall be entitled to security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities that might be
      incurred by it in compliance with such request or direction.

  
    35 

    
      
 

  

   

  SECTION 513.          Waiver of Past Defaults. Except as may otherwise be provided pursuant to Section 301 for all or any specific Securities of any series, the Holders of not less than a majority in principal
      amount (including waivers obtained in connection with a purchase of, or tender offer or exchange offer for, Securities) (1) of the Securities at the time Outstanding (voting as a single class) or (2) if fewer than all of the series of the Securities
      at the time Outstanding are to be affected by such waiver, of all series to be affected by such waiver (voting as a single class) may, by Act of such Holders, on behalf of the Holders of any series of Securities to be affected by such waiver, waive
      any past default hereunder with respect to the applicable series of Securities then Outstanding and its consequences, except a default

   

  (1) in the payment of the principal of or any premium or interest on any Security of such series, or

   

  (2) in respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

   

  Upon any such waiver with respect to any series, such default shall cease
      to exist, and any Event of Default arising therefrom shall be deemed to have been cured, with respect to such series for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right
      consequent thereon. A waiver of any past default and its consequences given by or on behalf of any Holder of Securities in connection with a purchase of, or tender or exchange offer for, such Holder’s Securities will not be rendered invalid by such
      purchase, tender or exchange.

   

  SECTION 514.          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, suffered or omitted by it as Trustee,
      a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs, including reasonable attorneys’ fees and expenses, against any such party litigant, in the manner and to the extent
      provided in the Trust Indenture Act; provided that neither this Section 514 nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the
      Issuers, any Guarantor or the Trustee or, if applicable, in any suit for the enforcement of the right to convert any Security in accordance with its terms.

   

  SECTION 515.          Waiver of Usury, Stay or Extension Laws. The Issuers covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or
      take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuers (to the extent that it may lawfully do
      so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as
      though no such law had been enacted.

   

  ARTICLE VI

      THE TRUSTEE

   

  SECTION 601.          Certain Duties and Responsibilities.

   

  (1) Except during the continuance of an Event of Default,

   

  (A) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and as are provided by the Trust Indenture Act, and no implied covenants or obligations shall be
      read into this Indenture against the Trustee; and

   

  (B) in the absence of bad faith 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 or opinions furnished to the
      Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine
      the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein).

   

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

  
    36 

    
      
 

  

   

  (3) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that

   

  (A) this Subsection shall not be construed to limit the effect of the first paragraph of this Section 601;

   

  (B) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer;

   

  (C) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding
      Securities of any series, determined as provided in Section 512, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under
      this Indenture with respect to the Securities of such series; and

   

  (D) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of
      its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate security or indemnity against such risk or liability is not reasonably assured to it. The Trustee shall not be required to give any bond
      or surety in respect of the performance of its power or duties hereunder.

   

  (4) Whether or not therein expressly so provided, 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 601.

   

  (5) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of the rights or powers vested in it
      by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities that might be incurred by it in
      compliance with such request or direction.

   

  SECTION 602.          Notice of Defaults. If a default or Event of Default occurs and is continuing hereunder with respect to Securities of any series, and if it is known to the Trustee, the Trustee shall mail or send
      to the Holders of Securities of such series notice of such default or Event of default within 90 days after the Trustee gains knowledge of the default or Event of Default unless such default or Event of Default shall have been cured or waived before
      the giving of such notice. Except in the case of a default or Event of Default in payment of principal of, premium or interest on Securities of any series, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers
      in good faith determines that withholding the notice is in the interests of the Holders of the Securities of such series. For the purpose of this Section 602 and Section 1005, the term “default” means, with respect to
      Securities of any series, any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series.

   

  SECTION 603.          Certain Rights of Trustee. Subject to the provisions of Section 601:

   

  (1) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent,
      order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

      evidenced by a Board Resolution of such Issuer;

   

  (3) 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 shall be
      entitled to receive and may, in the absence of bad faith on its part, conclusively rely upon, and shall not be liable for any action it takes or omits to take in good faith in reliance upon, an Officers’ Certificate or an Opinion of Counsel;

  
    37 

    
      
 

  

   

  (4) the Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action
      taken, suffered or omitted by it hereunder in good faith and in reliance thereon;

   

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

   

  (6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order,
      bond, debenture, note, other evidence of indebtedness 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 the books, records and premises of the Issuers personally or by agent or attorney at the sole cost of the Issuers and shall incur no liability or additional liability of any
      kind by reason of such inquiry or investigation;

   

  (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct
      or negligence on the part of any agent or attorney appointed with due care by it hereunder and shall not be responsible for the supervision of officers and employees of such agents or attorneys;

   

  (8) the Trustee may request that the Issuers deliver an Officers’ Certificate setting forth the names of individuals and titles of officers authorized at such time to take specified actions pursuant to this
      Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded;

   

  (9) the Trustee shall not be liable for any action taken, suffered or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred
      upon it by this Indenture;

   

  (10) the Trustee shall not be deemed to have notice of any default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in
      fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee from the Issuers or from the Holders of at least 25% of the aggregate principal amount of the Outstanding Securities of that series, and such notice
      references the Securities and this Indenture;

   

  (11) no Depositary shall be deemed an agent of the Trustee and the Trustee shall not be responsible for any act or omission by any clearinghouse or Depositary;

   

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

   

  (13) the rights, privileges, protections, immunities and benefits given to the Trustee, including its rights 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.

  
    38 

    
      
 

  

   

  SECTION 604.          Not Responsible for Recitals or Issuance of Securities. The recitals contained in the Indenture and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the
      statements of the Issuers, and the Trustee does not assume any responsibility for their correctness. The Trustee makes no representations as to and shall not be responsible for the validity or sufficiency of this Indenture or of the Securities. The
      Trustee shall not be accountable for the use or application by the Issuers of Securities or the proceeds thereof or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, and it shall not be responsible
      for the use or application of any money received by any Paying Agent other than the Trustee. The Trustee shall not be bound to ascertain or inquire as to the performance, observance, or breach of any covenants, conditions, representations, warranties
      or agreements on the part of the Issuers. Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Securities. The Trustee shall have no obligation to pursue any action that is not in
      accordance with applicable law. The Trustee shall not be responsible for and makes no representation as to any act or omission of any rating agency or any rating with respect to the Securities. The Trustee shall have no obligation to independently
      determine or verify if any event has occurred related to, or notify the Holders of any event dependent upon, the rating of the Securities, or if the rating on the Securities has been changed, suspended or withdrawn by any rating agency.

   

  SECTION 605.          May Hold Securities. The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Issuers, in its individual or any other capacity, may become the
      owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Issuers with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other
      agent.

   

  SECTION 606.          Money Held in Trust. Money held by the Trustee in trust hereunder need not be segregated from other funds and need not be held in an interest-bearing account, in each case, except to the extent
      required by law or by any other provision of this Indenture. The Trustee (acting in any capacity hereunder) shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Issuers.

   

  SECTION 607.          Compensation and Reimbursement.

   

  (1) The Issuers shall pay to the Trustee (in its capacity as Trustee, and, to the extent it has been appointed as such, as Paying Agent and Security Registrar) from time to time reasonable compensation for its
      acceptance of this Indenture and services hereunder in accordance with a written schedule provided by the Trustee to the Issuers. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers
      shall reimburse the Trustee promptly upon request for all reasonable and customary disbursements, advances and reasonable out-of-pocket expenses incurred or made by it in addition to the compensation for its services, except those resulting from its
      own negligent action, negligent failure to act or willful misconduct. Such expenses shall include the reasonable and customary compensation, disbursements and expenses of the Trustee’s agents and counsel.

   

  (2) The Issuers shall indemnify and hold harmless the Trustee in its capacity against any and all losses, liabilities, damage, claim, fee, cost, or reasonable out-of-pocket expenses incurred by it arising out of
      or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuers (including this Section 607) and defending itself against any claim
      (whether asserted by either of the Issuers or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be
      attributable to its negligence, bad faith or willful misconduct as finally adjudicated by a court of competent jurisdiction. The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so
      notify the Issuers shall not relieve the Issuers of its obligations hereunder. The Issuers shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may elect to have separate counsel defend the claim, but the Issuers shall
      be obligated to pay the reasonable fees and expenses of such separate counsel only if the Issuers fails to assume the Trustee’s defense or there is a conflict of interest between the Issuers, on the one hand, and the Trustee, on the other hand, with
      respect to the claim, as reasonably determined by the Trustee. The Issuers need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The Issuers need not reimburse the Trustee for any expense or
      indemnity against liability or loss of the Trustee to the extent such expense, liability or loss is attributable to the negligence, bad faith or willful misconduct of the Trustee as finally adjudicated by a court of competent jurisdiction. The
      provisions of this Section 607(2) shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

  
    39 

    
      
 

  

   

  (3) As security for the performance of the obligations of the Issuers under this Section 607 the Trustee shall have a lien prior to the Securities of any series upon all property and funds held or
      collected by the Trustee as such, except funds held in trust for the payment of principal of (and premium, if any) or interest on Securities of such series. Such lien shall survive satisfaction and discharge of this Indenture.

   

  (4) Without limiting any rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(5) or Section



        501(6), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency or
      other similar law. To the extent that the payment of any such expenses of the Trustee, its agents and counsel, and any other amounts due the Trustee out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall
      be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization
      or arrangement or otherwise. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ committee or other similar committee.

   

  (5) The provisions of this Section 607 shall survive the termination of this Indenture.

   

  SECTION 608.          Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the
      extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being
      a trustee under this Indenture with respect to Securities of more than one series.

   

  SECTION 609.          Corporate Trustee Required; Eligibility. There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee hereunder for
      Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and surplus of at least $100,000,000 and has its Corporate Trust Office in the
      continental United States of America. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section 609 and to the
      extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with
      respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section 609, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

   

  SECTION 610.          Resignation and Removal; Appointment of Successor. No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the
      acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 611.

   

  The Trustee may resign at any time (in its capacity as Trustee or other
      capacities including Paying Agent) with respect to the Securities of one or more series by giving written notice thereof to the Issuers. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been
      delivered to the Trustee within 60 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Issuers, any court of competent jurisdiction for the appointment of a successor Trustee with respect to
      the Securities of such series.

   

  The Trustee may be removed at any time with respect to the Securities of
      any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Issuers. If the instrument of acceptance by a successor Trustee required by Section 611 shall



      not have been delivered to the Trustee within 30 days after the giving of a notice of removal pursuant to this paragraph, the Trustee being removed may petition, at the expense of the Issuers, any court of competent jurisdiction for the appointment
      of a successor Trustee with respect to the Securities of such series.

   

  If at any time:

   

  (1) the Trustee shall fail to comply with Section 608 after written request therefor by the Issuers or by any Holder who has been a bona fide Holder of a Security for at least six months, or

  
    40 

    
      
 

  

   

  (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Issuers or by any such Holder, or

   

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

   

  then, in any such case, (A) the Issuers by a Board Resolution may remove the Trustee with
      respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
      jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

   

  If the Trustee shall resign, be removed or become incapable of acting, or
      if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Issuers, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that
      or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any
      particular series) and shall comply with the applicable requirements of Section 611. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal,
      the Trustee being removed may petition, at the expense of the Issuers, any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. If, within one year after such resignation, removal
      or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to
      the Issuers and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the
      Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted
      appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of
      competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

   

  The Issuers shall give notice of each resignation and each removal of the
      Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106. Each notice shall
      include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office.

   

  SECTION 611.          Acceptance of Appointment by Successor. In case of the appointment hereunder of a successor Trustee with respect to all Securities, such successor Trustee so appointed shall execute, acknowledge
      and deliver to the Issuers and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or
      conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Issuers or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an
      instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

   

  In case of the appointment hereunder of a successor Trustee with respect
      to the Securities of one or more (but not all) series, the Issuers, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor
      Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee
      with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary
      or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring
      Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such
      supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such
      Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or
      conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Issuers
      or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the
      appointment of such successor Trustee relates.

  
    41 

    
      
 

  

   

  Upon request of any such successor Trustee, the Issuers shall execute any
      and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be.

   

  No successor Trustee shall accept its appointment unless at the time of
      such acceptance such successor Trustee shall be qualified and eligible under this Article.

   

  SECTION 612.          Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting
      from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such
      corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not
      delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee
      had itself authenticated such Securities.

   

  SECTION 613.          Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Issuers (or any other obligor upon the Securities), the Trustee shall be subject to
      the provisions of the Trust Indenture Act regarding the collection of claims against the Issuers (or any such other obligor).

   

  SECTION 614.          Appointment of Authenticating Agent. The Trustee may appoint an Authenticating Agent or Agents with respect to any series of Securities which shall be authorized to act on behalf of the Trustee
      to authenticate the Securities of such Series issued upon original issue and upon exchange, registration of transfer, partial conversion or partial redemption or pursuant to Section 306, and Securities of such series so authenticated shall be
      entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities of such series
      by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent so appointed with respect to such series and a certificate of
      authentication executed on behalf of the Trustee by an Authenticating Agent so appointed with respect to such series. Each Authenticating Agent shall be acceptable to the Issuers and shall at all times be a corporation organized and doing business
      under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or
      examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section 614,
      the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible
      in accordance with the provisions of this Section 614, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section 614.

   

  Any corporation into which an Authenticating Agent may be merged or
      converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust
      business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section 614, without the execution or filing of any paper or any further act on the part of
      the Trustee, the Issuers, the Authenticating Agent or such successor corporation.

  
    42 

    
      
 

  

   

  An Authenticating Agent may resign at any time by giving written notice
      thereof to the Trustee and to the Issuers. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Issuers. Upon receiving such a notice of resignation or
      upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 614, the Trustee may appoint a successor Authenticating Agent with respect to any series of
      Securities which shall be acceptable to the Issuers and shall give notice of such appointment to all Holders of Securities of such series in the manner provided in Section 106. Any successor Authenticating Agent upon acceptance of its
      appointment hereunder shall become vested with all rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under
      the provisions of this Section 614.

   

  If an appointment is made pursuant to this Section 614 with
      respect to Securities of any series, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

   

  This is one of the Securities of the series designated herein and referred
      to in the within-mentioned Indenture.

   

  	 	
          U.S. Bank Trust Company, National Association, 

          as Trustee

        
	 	 	 
	 	By:	[NAME OF AUTHENTICATING AGENT],

            as Authenticating Agent
	 	 	 
	 	By:	 
	 	 	Authorized Signatory

  The rights of Holders to communicate with other Holders with respect to
      their rights under this Indenture or under the Securities, and the corresponding rights and privileges of the Trustee, shall be as provided by the Trust Indenture Act.

   

  Every Holder of Securities, by receiving and holding the same, agrees with
      the Issuers, any Guarantors and the Trustee that none of the Issuers, the Guarantors or the Trustee nor any agent of any of them shall be held accountable by reason of any disclosure of information as to names and addresses of Holders made pursuant
      to the Trust Indenture Act.

  
    43 

    
      
 

  

   

  SECTION 703.          Reports by Trustee. The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to Section 313 of the Trust

  A copy of each such report shall, at the time of such transmission to
      Holders, be filed by the Trustee with each stock exchange upon which any Securities are listed, with the Commission and with the Issuers. The Issuers will notify the Trustee when any Securities are listed on any stock exchange and of any delisting
      thereof.

   

  SECTION 704.          Reports by Issuers. To the extent any Securities of any series are outstanding, the Issuers will furnish or file with the Trustee, within 15 days after it files the same with the Commission,

      information with the SEC via the EDGAR filing system or otherwise made such reports or information publicly available on a freely accessible page on the Company’s website. Delivery of any reports, information and documents to the Trustee is for

      covenants under this Indenture or the Securities (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuers’
      compliance with the covenants under this Indenture or the Securities or with respect to any reports or other documents filed with the Commission through the EDGAR system or any website under this Indenture.

  SECTION 902.          Supplemental Indentures With Consent of Holders. Except as may otherwise be provided pursuant to Section 301 for all or any specific Securities of any series, with the consent of the
      Holders of not less than a majority in principal amount (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities) (1) of the Securities at the time Outstanding (voting as a single class) or (2)
      if fewer than all of the series of the Securities at the time Outstanding are affected by such supplemental indenture, of all series affected by such supplemental indenture (voting as a single class), by Act of said Holders delivered to the Issuers

      indenture shall, without the consent of the Holder of each Outstanding Security affected thereby (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities),

   

  (1) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon or any premium payable
      upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount Security or any other Security which would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502,
      or permit the Issuers to redeem any Security if, absent such supplemental indenture, the Issuers would not be permitted to do so, or change any Place of Payment where, or the coin or currency in which, any Security or any premium or interest thereon

      therein, or

  
    46

  It shall not be necessary for any Act of Holders under this Section
        902 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. A consent to any indenture supplemental hereto by or on behalf of any Holder of Securities
      given in connection with a purchase of, or tender or exchange offer for, such Holder’s Securities will not be rendered invalid by such purchase, tender or exchange.

   

  SECTION 903.          Execution of Supplemental Indentures. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts
      created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel and Officers’ Certificate stating that the execution of such supplemental
      indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

   

  SECTION 904.          Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture
      shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

   

  SECTION 905.          Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

   

  SECTION 906.          Reference in Securities to Supplemental Indentures. Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall
      if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Issuers shall so determine, new Securities of any series so modified as to conform, in the opinion of the
      Trustee and the Issuers, to any such supplemental indenture may be prepared and executed by the Issuers and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series.

   

  ARTICLE X

      COVENANTS

   

  SECTION 1001.       Payment of Principal, Premium and Interest. The Issuers covenant and agree for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and
      interest on the Securities of that series in accordance with the terms of the Securities and this Indenture.

   

  SECTION 1002.       Maintenance of Office or Agency. The Issuers will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or
      surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange, where Securities may be surrendered for conversion and where notices and demands to or upon the Issuers in respect of the Securities
      of that series and this Indenture may be served. The Issuers will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuers shall fail to maintain any such required
      office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Issuers hereby appoint the Trustee as its
      agent to receive all such presentations, surrenders, notices and demands. The Issuers shall cause each of the Security Registrar and the Paying Agent to maintain an office or agency in the Borough of Manhattan, The City of New York.

  
    47 

    
      
 

  

   

  The Issuers may also from time to time designate one or more other offices
      or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall
      in any manner relieve the Issuers of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Issuers will give prompt written notice to the Trustee of any such designation or
      rescission and of any change in the location of any such other office or agency.

   

  With respect to any Global Security, and except as otherwise may be
      specified for such Global Security as contemplated by Section 301, the Corporate Trust Office of the Trustee shall be the Place of Payment where such Global Security may be presented or surrendered for payment or for registration of transfer
      or exchange, or where successor Securities may be delivered in exchange therefor; provided, however, that any such payment, presentation, surrender or delivery effected pursuant to the Applicable Procedures of the Depositary for such
      Global Security shall be deemed to have been effected at the Place of Payment for such Global Security in accordance with the provisions of this Indenture.

   

  SECTION 1003.       Money for Securities Payments to Be Held in Trust. If the Issuers shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of
      the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until
      such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

   

  Whenever the Issuers shall have one or more Paying Agents for any series
      of Securities, it will, on or prior to 11:00 A.M., New York City time, on each due date of the principal of or any premium or interest on any Securities of that series, deposit (or, if the Issuers have deposited any trust funds with a trustee
      pursuant to Section 1304(1), cause such trustee to deposit) with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Issuers will
      promptly notify the Trustee of its action or failure so to act.

   

  The Issuers will cause each Paying Agent for any series of Securities
      other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 1003, that such Paying Agent will (1) comply with the provisions of
      the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Issuers (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that
      series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series.

   

  The Issuers may at any time, for the purpose of obtaining the satisfaction
      and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Issuers or such Paying Agent, such sums to be held by the Trustee upon the same trusts as
      those upon which such sums were held by the Issuers or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

   

  Any money deposited with the Trustee or any Paying Agent, or then held by
      the Issuers, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Issuers
      on Company Request, or (if then held by the Issuers) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Issuers for payment thereof, and all liability of the
      Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any
      such repayment, shall, at the expense of the Issuers, cause to be published once, in The New York Times or 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 publication, any unclaimed balance of such money then remaining will be repaid to the Issuers.

  
    48 

    
      
 

  

   

  SECTION 1004.       Organizational Existence. Subject to Article VIII, each Issuer will do or cause to be done all things necessary to preserve and keep in full force and effect its organizational
      existence, rights (charter and statutory), licenses and franchises; provided, however, that no Issuer will not be required to preserve any such right, license or franchise if it shall determine that the preservation thereof is no longer
      desirable in the conduct of the business of such Issuer.

   

  SECTION 1005.       Statement by Officers as to Default. The Issuers shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’
      Certificate complying with Section 314(a)(4) of the Trust Indenture Act, stating that a review of the activities of the Issuers during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining
      whether the Issuers have kept, observed, performed and fulfilled its obligations under this Indenture, and compliance with conditions and covenants, with respect to the Securities of each series Outstanding and further stating, as to each such
      Officer signing such certificate, that to the best of such Officer’s actual knowledge, the Issuers have kept, observed, performed and fulfilled its obligations, conditions and covenants under this Indenture with respect to Securities of such series
      and is not in default in the performance and observance of any of the material terms, provisions and conditions of this Indenture with respect to Securities of such series, in each case, so as not to result in any default or Event of Default with
      respect to Securities of such series (or, if a default or Event of Default with respect to Securities of such series shall have occurred and be continuing, describing all such defaults or Events of Default of which such Officer may have knowledge and
      what action the Issuers are taking or propose to take with respect thereto).

   

  SECTION 1006.       Waiver of Certain Covenants. Except as otherwise provided pursuant to Section 301 for all or any specific Securities of any series, the Issuers may, with respect to all or any Securities
      of any series, omit in any particular instance to comply with any term, provision or condition set forth in Section 1004 or in any covenant provided pursuant to Section 301(18), 901(2), 901(6) or 901(8) for the
      benefit of the Holders of such series or in Article VIII if, before the time for such compliance, the Holders of not less than a majority in principal amount (including waivers obtained in connection with a purchase of, or tender offer or
      exchange offer for, Securities) (1) of all the Securities at the time Outstanding (voting as a single class) or (2) if fewer than all of the series of the Securities at the time Outstanding are affected by such omission, of the series affected by
      such waiver (voting as a single class) shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term,
      provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Issuers and the duties of the Trustee in respect of any such term, provision or condition shall remain in full
      force and effect. A waiver of compliance given by or on behalf of any Holder of Securities in connection with a purchase of, or tender or exchange offer for, such Holder’s Securities will not be rendered invalid by such purchase, tender or exchange.

   

  ARTICLE XI

      REDEMPTION OF SECURITIES

   

  SECTION 1101.       Applicability of Article. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as
      contemplated by Section 301 for such Securities) in accordance with this Article.

   

  SECTION 1102.       Election to Redeem; Notice to Trustee. The election of the Issuers to redeem any Securities shall be established in or pursuant to a Board Resolution or in another manner specified as
      contemplated by Section 301 for such Securities. In case of any redemption at the election of the Issuers of less than all the Securities of any series (including any such redemption affecting only a single Security), the Issuers shall, at
      least 5 Business Days prior to delivery of notice of redemption to Holders of Securities fixed by the Issuers (unless a shorter notice shall be satisfactory to the Trustee), deliver a Company Request to Trustee, together with the notice to be given,
      and notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities (1) prior to the
      expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, or (2) pursuant to an election of the Issuers that is subject to a condition specified in the terms of the Securities of the
      series to be redeemed, the Issuers shall furnish the Trustee with an Officers’ Certificate and Opinion of Counsel evidencing compliance with such restriction or condition. Redemptions may be conditioned upon the occurrence of conditions precedent
      with respect to the redemption.

  
    49 

    
      
 

  

   

  SECTION 1103.       Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be
      redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not
      previously called for redemption, in the case of Global Securities by Applicable Procedures or otherwise by pro rata method and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series,
      provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If required by Applicable Procedures for Global
      Securities, or otherwise for Definitive Securities, if less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be
      selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence.

   

  If any Security selected for partial redemption is converted in part
      before termination of the conversion right (if applicable to the relevant series of Securities) with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as it may be) to be the portion
      selected for redemption. Securities which have been converted during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection.

   

  The Trustee shall promptly notify the Issuers and each Security Registrar
      in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed.

   

  The provisions of the two preceding paragraphs shall not apply with
      respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an
      authorized denomination (which shall not be less than the minimum authorized denomination) for such Security.

   

  For all purposes of this Indenture, unless the context otherwise requires,
      all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

   

  SECTION 1104.       Notice of Redemption. Notice of redemption shall be given in the manner provided in Section 106 not less than 10 days nor more than 60 days prior to the Redemption Date (or within such
      period as otherwise specified as contemplated by Section 301 for the relevant Securities), to each Holder of Securities to be redeemed, at its address appearing in the Security Register.

   

  All notices of redemption shall identify the Securities to be redeemed
      (including CUSIP numbers, if any, and that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such noticed or printed on the Securities), the paragraph of the Securities and the Section of the Indenture
      pursuant to which the Securities called for redemption are being redeemed, and shall state:

   

  (1) the Redemption Date,

   

  (2) the Redemption Price,

   

  (3) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the
      principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed,

  
    50 

    
      
 

  

   

  (4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

   

  (5) the place or places where each such Security is to be surrendered for payment of the Redemption Price,

   

  (6) the conditions precedent for the redemption, if any,

   

  (7) for any Securities that by their terms may be converted, the terms of conversion, the date on which the right to convert the Security to be redeemed will terminate and the place or places where such
      Securities may be surrendered for conversion, and

   

  (8) that the redemption is for a sinking fund, if such is the case.

   

  Notice of redemption of Securities to be redeemed at the election of the
      Issuers shall be given by the Issuers or, by Company Request, by the Trustee in the name and at the expense of the Issuers.

   

  SECTION 1105.       Deposit of Redemption Price. Prior to 11:00 A.M., New York City time, on any Redemption Date, the Issuers shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as
      the Issuers’ Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all
      the Securities which are to be redeemed on that date, other than any Securities called for redemption on that date which have been converted prior to the date of such deposit.

   

  If any Security called for redemption is converted, any money deposited
      with the Trustee or with any Paying Agent or so segregated and held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any Predecessor Security to receive interest as provided in the last
      paragraph of Section 307 or in the terms of such Security) be paid to the Company upon Company Request or, if then held by the Company, shall be discharged from such trust.

   

  SECTION 1106.       Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the
      Redemption Price therein specified, and from and after such date (unless the Issuers shall default in the payment of the Redemption Price and accrued interest or unless the conditions precedent for the redemption have not been satisfied) such
      Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Issuers at the Redemption Price, together with accrued interest to the Redemption Date; provided,
      however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more
      Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

   

  If any Security called for redemption shall not be so paid upon surrender
      thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

   

  SECTION 1107.       Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Issuers or the Trustee so requires, due
      endorsement by, or a written instrument of transfer in form satisfactory to the Issuers and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Issuers and the Trustee shall authenticate and deliver
      to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the
      unredeemed portion of the principal of the Security so surrendered.

   

  SECTION 1108.       No Limit on Repurchases. Nothing in this Indenture or the Securities shall prohibit or limit the right of the Issuers or any Affiliate of the Issuers to repurchase Securities from time to time at
      any price in open market purchases or private transactions at negotiated prices, by tender offer or otherwise, in each case without any notice to or consent by Holders. Any Securities purchased by the Issuers or any Affiliate of the Issuers may, to
      the extent permitted by law and at the discretion of the Issuers, be held, resold or delivered to the Trustee for cancellation. Any such Securities delivered to the Trustee for cancellation may not be resold and shall be disposed of as directed by
      Company Order.

  
    51 

    
      
 

  

   

  ARTICLE XII

      SINKING FUNDS

   

  SECTION 1201.       Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise specified as contemplated by Section



        301 for such Securities.

   

  The minimum amount of any sinking fund payment provided for by the terms
      of any Securities is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an “optional sinking fund
          payment.” If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of
      Securities as provided for by the terms of such Securities.

   

  SECTION 1202.       Satisfaction of Sinking Fund Payments with Securities. The Issuers (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a
      credit Securities of a series which have been converted in accordance with their terms or which have been redeemed either at the election of the Issuers pursuant to the terms of such Securities or through the application of permitted optional sinking
      fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to
      the extent provided for by the terms of such Securities; provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at
      the Redemption Price, as specified in the Securities so to be redeemed (or at such other prices as may be specified for such Securities as contemplated in Section 301), for redemption through operation of the sinking fund and the amount of
      such sinking fund payment shall be reduced accordingly.

   

  SECTION 1203.       Redemption of Securities for Sinking Fund. Not less than 45 days (or such shorter period as shall be satisfactory to the Trustee) prior to each sinking fund payment date for any Securities, the
      Issuers will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to be satisfied by payment
      of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 1202 and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days prior to each such
      sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the
      expense of the Issuers in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107.

   

  ARTICLE XIII

      DEFEASANCE AND COVENANT DEFEASANCE

   

  SECTION 1301.       Issuers’ Option to Effect Defeasance or Covenant Defeasance. Unless otherwise designated pursuant to Section 301(15), the Securities of any series of Securities shall be subject to
      defeasance or covenant defeasance pursuant to such Section 1302 or 1303, in accordance with any applicable requirements provided pursuant to Section 301 and upon compliance with the conditions set forth below in this Article.
      The Issuers may elect, at its option, at any time, to have Section 1302 or Section 1303 applied to any Securities or any series of Securities so subject to defeasance or covenant defeasance. Any such election shall be evidenced by a
      Board Resolution or in another manner specified as contemplated by Section 301 for such Securities.

  
    52 

    
      
 

  

   

  SECTION 1302.       Defeasance and Discharge. Upon the Issuers’ exercise of its option (if any) to have this Section 1302 applied to any Securities or any series of Securities, as the case may be, the
      Issuers and the Guarantors shall be deemed to have been discharged from its obligations with respect to such Securities as provided in this Section 1302 on and after the date the conditions set forth in Section 1304 are satisfied
      (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Issuers and the Guarantors shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all
      their other respective obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Issuers, shall execute proper instruments acknowledging the same), subject to the following
      which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 1304(1) and as more fully set forth in such Section, payments in
      respect of the principal of and any premium and interest on such Securities when payments are due, or, if applicable, to convert such Securities in accordance with their terms, (2) the obligations of the Issuers and the Guarantors with respect to
      such Securities under Sections 304, 305, 306, 1002 and 1003, and, if applicable, their obligations with respect to the conversion of such Securities, (3) the rights, powers, trusts, duties and immunities of the
      Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Issuers may exercise their option (if any) to have this Section 1302 applied to any Securities notwithstanding the prior exercise of its option (if any) to
      have Section 1303 applied to such Securities.

   

  SECTION 1303.       Covenant Defeasance. Upon the Issuers’ exercise of its option (if any) to have this Section 1303 applied to any Securities or any series of Securities, as the case may be, (1) the Issuers
      and the Guarantors shall be released from its obligations under Section 1004 and any covenants provided pursuant to Section 301(18), 901(2), 901(6) or 901(8) for the benefit of the Holders of such Securities
      and (2) the occurrence of any event specified in Sections 501(4) (with respect to Section 1004 and any such covenants provided pursuant to Section 301(18), 901(2), 901(6) or 901(7)) and 501(7)
      shall be deemed not to be or result in an Event of Default, in each case with respect to such Securities as provided in this Section 1303 on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called
      “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Issuers and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or
      limitation set forth in any such specified Section (to the extent so specified in the case of Section 501(4)), whether directly or indirectly by reason of any reference elsewhere herein to any such Section or by reason of any reference in any
      such Section to any other provision herein or in any other document, but the remainder of this Indenture and such Securities thereof shall be unaffected thereby.

   

  SECTION 1304.       Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to the application of Section 1302 or Section 1303. to any Securities or any series of
      Securities, as the case may be:

   

  (1) The Issuers shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies the requirements contemplated by Section 609 and agrees to comply with the
      provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of such Securities, (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 one day before the due date of any payment, money in an amount, or
      (C) such other obligations or arrangements as may be specified as contemplated by Section 301 with respect to such Securities, or (D) a combination thereof, in each case sufficient (except in the case of clause (A), in the opinion of a
      nationally recognized firm of independent public accountants or a nationally recognized investment banking firm expressed in a written certification thereof delivered to the Trustee) to pay and discharge, and which shall be applied by the Trustee (or
      any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S.



          Government Obligation” means (x) any security which is (i) a direct obligation of the United States of America for the timely payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a
      Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in
      either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government
      Obligation which is specified in Clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so
      specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S.
      Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt.

  (2) In the event of an election to have Section 1302 apply to any Securities or any series of Securities, as the case may be, the Issuers shall have delivered to the Trustee an Opinion of Counsel, subject
      to customary exceptions and exclusions, stating that (A) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable Federal
      income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize income, gain or loss for Federal income tax purposes as a result of the deposit,
      Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, Defeasance and discharge were
      not to occur.

   

  (3) In the event of an election to have Section 1303 apply to any Securities or any series of Securities, as the case may be, the Issuers shall have delivered to the Trustee an Opinion of Counsel, subject
      to customary exceptions and exclusions, to the effect that the Holders of such Securities will not recognize income, gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such
      Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and Covenant Defeasance were not to occur.

   

  (4) The Issuers shall have delivered to the Trustee an Officers’ Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will
      be delisted as a result of such deposit.

   

  (5) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities or any other Securities (other than such an event or Event of Default with respect
      to such Securities resulting solely from the incurrence of indebtedness or other borrowing of funds, or the grant of liens securing such indebtedness or other borrowing, all or a portion of which are to be applied to such deposit) shall have occurred
      and be continuing at the time of such deposit.

   

  (6) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument (other than this Indenture insofar as such Securities are
      concerned) to which the Issuers are a party or by which they are bound.

   

  (7) The Issuers shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders of such Securities over the other
      creditors of the Issuers or with the intent of defeating, hindering, delaying or defrauding creditors of the Issuers.

   

  (8) The Issuers 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 1305.       Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1303, all money, U.S. Government
      Obligations and other obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section 1305 and Section 1306, the Trustee and any such other trustee are referred
      to collectively as the “Trustee”) pursuant to Section 1304 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment,
      either directly or through any such Paying Agent (including the Company acting as the Issuers’ Paying Agent or any Subsidiary or Affiliate of the Company) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become
      due thereon in respect of principal and any premium and interest, but money and U.S. Government Obligations so held in trust need not be segregated from other funds except to the extent required by law.

   

  The Issuers shall pay and indemnify the Trustee against any tax, fee or
      other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1304 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 Outstanding Securities.

  
    54 

    
      
 

  

   

  Anything in this Article to the contrary notwithstanding, the Trustee
      shall deliver or pay to the Issuers from time to time upon Company Request any money, U.S. Government Obligations or other obligations held by it as provided in Section 1304 with respect to any Securities which, in the opinion of a nationally
      recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance,
      as the case may be, with respect to such Securities.

   

  SECTION 1306.       Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or
      governmental authority enjoining, restraining or otherwise prohibiting such application, then the respective obligations under this Indenture and such Securities from which the Issuers and the Guarantors have been discharged or released pursuant to Section



        1302 or 1303 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust
      pursuant to Section 1305 with respect to such Securities in accordance with this Article; provided, however, that if the Issuers make any payment of principal of or any premium or interest on any such Security following such
      reinstatement of its obligations, the Issuers shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust.

   

  ARTICLE XIV

      GUARANTEES

   

  SECTION 1401.       Guarantees. Securities of any series that are to be guaranteed by the Guarantees of any Guarantors shall be guaranteed by such Guarantors as shall be established pursuant to Section 301
      with respect to the Securities of such series. The Persons who shall initially be the Guarantors of the Securities of any such series may, but need not, include any or all of the Initial Guarantors and may include any and all such other Persons as
      the Issuers may determine; provided that, prior to the authentication and delivery upon original issuance of Securities that are to be guaranteed by a Person that is not an Initial Guarantor, the Issuers, the Trustee and such Person shall
      enter into a supplemental indenture pursuant to Section 901 hereof whereby such Person shall become a Guarantor under this Indenture.

   

  Securities of any series that are to be guaranteed by the Guarantees of
      any Guarantors shall be guaranteed in accordance with the terms of such Guarantees as established pursuant to Section 301 with respect to such Securities and such Guarantees thereof and (except as otherwise specified as contemplated by Section 301 for



      such Securities and such Guarantees thereof) in accordance with this Article.

   

  Each Guarantor of any Security hereby fully and unconditionally, jointly
      and severally, guarantees to each Holder of such Security, and to the Trustee on behalf of such Holder, the due and punctual payment of the principal of, and premium, if any, and interest, if any, on such Security when and as the same shall become
      due and payable, whether at the Stated Maturity, by declaration of acceleration, call for redemption or otherwise, in accordance with the terms of such Security and of this Indenture. In case of the failure of the Issuers punctually to make any such
      payment, such Guarantor hereby agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such
      payment were made by the Issuers.

   

  The Guarantor of any Security hereby agrees that its obligations
      hereunder shall be absolute and unconditional irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or this Indenture, any failure to enforce the provisions of such Security or this Indenture,
      or any waiver, modification or indulgence granted to the Issuers with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge or defense of a surety or
      guarantor; provided, however, that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of any Guarantor, increase the principal amount of such Security, or increase the interest rate
      thereon, change any redemption provisions thereof (including any change to increase any premium payable upon redemption thereof) or change the Stated Maturity of any payment thereon, or increase the principal amount of any Original Issue Discount
      Security that would be due and payable upon a declaration of acceleration or the maturity thereof pursuant to Section 502 of this Indenture.

  
    55 

    
      
 

  

   

  The Guarantor of any Security hereby waives the benefits of diligence,
      presentment, demand for payment, any requirement that the Trustee or any of the Holders exhaust any right or take any action against the Issuers or any other Person, filing of claims with a court in the event of insolvency or bankruptcy of any
      Issuer, any right to require a proceeding first against any Issuer, protest or notice with respect to any Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that its obligations hereunder will not be discharged
      in respect of such Security except by complete performance of the obligations of such Guarantor contained in such Security and in this Indenture. Any Guarantee of any Guarantor hereunder shall constitute a guaranty of payment and not of collection.
      The Guarantor of any Security hereby agrees that, in the event of a default in payment of principal, or premium, if any, or interest, if any, on such Security, whether at its Stated Maturity, by declaration of acceleration, call for redemption or
      otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Security, subject to the terms and conditions set forth in this Indenture, directly against such Guarantor to enforce the obligation of such
      Guarantor hereunder without first proceeding against any Issuer.

   

  The obligations of the Guarantor of any Security hereunder with respect
      to such Security shall be continuing and irrevocable until the date upon which the entire principal of, premium, if any, and interest, if any, on such Security has been, or has been deemed pursuant to the provisions of Article IV of this
      Indenture to have been, paid in full or otherwise discharged.

   

  The Guarantor of any Security shall be subrogated to all rights of the
      Holders of such Security against the Issuers in respect of any amounts paid by the Guarantor on account of such Security pursuant to the provisions of this Indenture; provided, however, that such Guarantor shall not be entitled to
      enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal, and premium, if any, and interest, if any, on all Securities issued hereunder that are due and payable shall have been paid in full.

   

  The Guarantee by any Guarantor of any Security shall remain in full
      force and effect and continue notwithstanding any petition filed by or against any Issuer for liquidation or reorganization, any Issuer becoming insolvent or making an assignment for the benefit of creditors or a receiver or trustee being appointed
      for all or any significant part of any Issuer’s assets, and shall, to the fullest extent permitted by law, continue to be effective or reinstated, as the case may be, if at any time payment of such Security, is, pursuant to applicable law, rescinded
      or reduced in amount, or must otherwise be restored or returned by any Holder of such Security, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that
      any payment, or any part thereof, is rescinded, reduced, restored or returned on a Security, such Security shall, to the fullest extent permitted by law, be reinstated and deemed paid only by such amount paid and not so rescinded, reduced, restored
      or returned.

   

  No Guarantor shall consolidate with or merge into any other Person or
      sell, convey or transfer all or substantially all its properties and assets to any Person, and no Guarantor shall permit any Person to consolidate with or merge into such Guarantor, in each case in a transaction in which the successor Person formed
      by such consolidation or merger or to which such sale, conveyance or transfer is made is an Affiliate of the Company, and no Guarantor shall lease all or substantially all its properties and assets to any Person (whether or not such an Affiliate),
      unless, in any such case:

   

  (1) in case such Guarantor shall consolidate with or merge into another Person or sell, convey, transfer or lease all or substantially all its properties and assets to any Person, the Person formed by such
      consolidation or into which such Guarantor is merged or the Person which acquires by sale, conveyance or transfer, or which leases, all or substantially all the properties and assets of such Guarantor shall be a corporation, limited liability
      company, partnership or trust, shall be organized and validly existing under the laws of the United States, any state thereof or the District of Columbia and shall expressly assume, by an indenture supplemental hereto, executed and delivered to the
      Trustee, in form reasonably satisfactory to the Trustee, the performance or observance of every covenant of this Indenture and any Guarantees on the part of such Guarantor to be performed or observed; and

   

  (2) immediately after giving effect to such transaction no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing.

  
    56 

    
      
 

  

   

  Upon any consolidation of any Guarantor with, or merger of such Guarantor into, any other
      Person or any sale, conveyance, transfer or lease of all or substantially all the properties and assets of such Guarantor in accordance with this paragraph, the successor Person formed by such consolidation or into which such Guarantor is merged or
      to which such sale, conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, such Guarantor under this Indenture with the same effect as if such successor Person had been named as such
      Guarantor herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and any Guarantees of such Guarantor.

   

  Upon (i) a consolidation or merger of any Guarantor with or into, or a
      sale, conveyance or transfer of all or substantially all the properties and assets of any Guarantor to, any other Person or any consolidation or merger of any Person with or into any Guarantor, in each case in a transaction in which the successor
      Person formed by such consolidation or merger or to which such sale, conveyance or transfer is made is not an Affiliate of the Company or (ii) any sale, conveyance or transfer (including by way of merger) by the Company or any Subsidiary thereof of
      all or substantially all the capital stock of any Guarantor to any Person that is not an Affiliate of the Company, such Guarantor shall be deemed to be automatically and unconditionally released and discharged from all its obligations under its
      Guarantees and under this Article XIV without any further action required on the part of the Trustee or any Holder. The Trustee shall deliver an appropriate instrument evidencing such release and discharge upon receipt of an Issuer Request
      accompanied by an Officers’ Certificate certifying as to the compliance with this paragraph of Section 1401. The Company may, at its option, at any time and from time to time, cause any Guarantor to be automatically and unconditionally
      released and discharged from all its obligations under its Guarantees with respect to Securities of all series guaranteed by Guarantees of such Guarantor and under this Article XIV upon (i) any conditions for such release provided with respect
      to Securities of such series in accordance with Section 301 having been satisfied and (ii) delivery by the Company to the Trustee of an Issuer Order relating to such release and discharge. The Trustee shall deliver an appropriate instrument
      evidencing such release and discharge upon receipt of an Issuer Request accompanied by an Officers’ Certificate certifying as to the compliance with this paragraph of Section 1401.

   

  Anything in this Indenture, the Securities or any Guarantee to the
      contrary notwithstanding, the obligations of any Guarantor under its Guarantees and this Indenture shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor, result in the
      obligations of such Guarantor under its Guarantees and this Indenture not constituting a fraudulent conveyance or fraudulent transfer under any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
      federal, state or other law affecting the rights of creditors generally.

   

  No Guarantee by any Guarantor of any Security, whether or not such
      Guarantee is or is to be endorsed thereon, shall be valid and obligatory for any purpose with respect to such Security until the certificate of authentication on such Security shall have been signed by or on behalf of the Trustee.
