  “Acquired Debt” means, with respect to any specified Person:

   

  (1) Indebtedness of any other Person existing at the time such other Person is
      merged with or into or became a Subsidiary of such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such
      specified Person, but excluding Indebtedness which is extinguished, retired or repaid in connection with such Person merging with or becoming a Subsidiary of such specific Person; and

  “Affiliate” of any specified Person means any other Person directly or indirectly
      controlling or controlled by or under direct or indirect common control with such specified Person. For purposes of this definition, “control,” as used with respect to any Person, means the possession, directly or indirectly, of the power to direct

      redemption price will be “Redemption Price (if the Sustainability Performance Target has been satisfied and the Company has provided the Satisfaction Notice to the Trustee)” in the table appearing in Section 3.07(c); provided, further, that
      if the Company shall fail to deliver to the Trustee an Officers’ Certificate certifying that the Company reasonably expects to satisfy the Sustainability Performance Target in respect of the Observation Period, then such redemption price will be set

      with any cash or Cash Equivalents plus the amount of any liabilities assumed) is reasonably equivalent to the Fair Market Value of the properties or assets to be received by the Company or such Restricted Subsidiary (together with any cash or Cash
      Equivalents plus the amount of any liabilities assumed); and provided further that any cash received must be applied in accordance with Section 4.10 hereof;

  (16) sales, transfers or other dispositions of investments in joint ventures to
      the extent required by, or made pursuant to, customary buy/sell arrangements between the joint venture parties set forth in joint venture arrangements and similar binding arrangements.

   

  “Attributable Debt” in respect of a sale-and-leaseback transaction means, at the
      time of determination, the present value of the obligation of the lessee for net rental payments during the remaining term of the lease included in such sale-and-leaseback transaction including any period for which such lease has been extended or
      may, at the option of the lessor, be extended. As used in the preceding sentence, “net rental payments” under any lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by the lessee
      thereunder, excluding any amounts required to be paid by such lessee on account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges. In the case of any lease that is terminable by the lessee upon payment of
      penalty, such net rental payment shall also include the amount of such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated. For purposes of this definition,
      present value shall be calculated using a discount rate equal to the rate of interest implicit in the subject transaction, determined in accordance with GAAP; provided, however, that if such sale-and-leaseback transaction results in a
      Finance Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of “Finance Lease Obligation.”

   

  “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for
      the relief of debtors.

   

  
    3 

    
      
 

  

   

  “Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule
      13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to have beneficial ownership of all securities
      that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time. The terms “Beneficial Ownership,” “Beneficially Owns” and
      “Beneficially Owned” have a corresponding meaning. For purposes of this definition, a Person shall be deemed not to Beneficially Own securities that are the subject of a stock or unit purchase agreement, merger agreement or similar agreement until
      consummation of the transactions or, as applicable, series of related transactions contemplated thereby.

      serving a similar function.

      interests, participations, rights or other equivalents (however designated) of corporate stock;

   

  (3) in the case of a partnership or limited liability company, partnership
      interests (whether general or limited) or membership interests; and

   

  (4) any other interest or participation that confers on a Person the right to
      receive a share of the profits and losses of, or distributions of assets of, the issuing Person, but excluding from all of the foregoing any debt securities convertible into Capital Stock, whether or not such debt securities include any right of
      participation with Capital Stock.

   

  “Cash Equivalents” means:

   

  (1) securities issued or fully guaranteed or insured by the United States
      government or any agency thereof having maturities of not more than twenty-four (24) months from the date of acquisition thereof;

  Notwithstanding the preceding, (a) a conversion of the Company from a limited liability
      company to a corporation, limited partnership or other form of entity or an exchange of all of the outstanding Equity Interests in one form of entity for Equity Interests in such other form of entity shall not constitute a Change of Control, so long
      as immediately following such conversion or exchange the “persons” (as defined above) who Beneficially Owned the Capital Stock of the Company immediately prior to such transactions continue to Beneficially Own in the aggregate more than 50% of the

      authentication. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

   

  The terms and provisions contained in the Notes will constitute, and are
      hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any
      provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

   

  (b)    Global Notes. Notes issued
      in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in

    28 

    
      
 

  

   

  (c)    Temporary Global Notes.
      Notes offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Temporary Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for
      the Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and authenticated by the Trustee as
      hereinafter provided. The Restricted Period will terminate upon the delivery by the Company to the Trustee of notice of the expiration of the Restricted Period, together with copies of certificates from Euroclear and Clearstream certifying that they
      have received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Note (except to the extent of any Beneficial Owners thereof who acquired an interest therein during
      the Restricted Period pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a 144A Global Note bearing a Private Placement Legend, all as contemplated by Section

      Global Note accordingly and (ii) increase and endorse the Regulation S Permanent Global Note accordingly. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be

  Section 2.02            Execution and Authentication.

   

  At least one Officer must sign the Notes for the Company by manual, facsimile or
      electronic signature.

   

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

   

  A Note will not be valid until authenticated by the manual, facsimile or electronic
      signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

   

  The Trustee will, upon receipt of a written order of the Company signed by an Officer of
      the Company (an “Authentication Order”), together with the other documents required by Sections 12.03 and 12.04, authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The
      aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

  The Trustee may appoint an authenticating agent acceptable to the Company to authenticate
      Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to
      deal with Holders or an Affiliate of the Company.

   

  Section 2.03            Registrar and Paying Agent.

   

  The Company will maintain an office or agency where Notes may be presented for
      registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company
      may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar
      without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee
      shall act as such. The Company’s Subsidiaries may act as Paying Agent or Registrar.

   

  The Company initially appoints The Depository Trust Company (“DTC”) to act as
      Depositary with respect to the Global Notes.

   

  The Company initially appoints the Trustee to act as the Registrar and Paying Agent at
      its Corporate Trust Office and to act as Custodian with respect to the Global Notes.

   

  Section 2.04            Paying Agent to Hold Money in Trust.

   

  The Company will require each Paying Agent other than the Trustee to agree in writing
      that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Company
      in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon
      payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the
      benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes.

   

  Section 2.05            Holder Lists.

   

  The Trustee will preserve in as current a form as is reasonably practicable the most
      recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee
      may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes.

   

  Section 2.06            Transfer and Exchange.

   

  (a)    Transfer and Exchange of
        Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such
      nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes if:

   

  
    30 

    
      
 

  

   

  (1) the Company delivers to the Trustee notice from the Depositary that it is
      unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days;

   

  (2) the Company, at its option but subject to the Depositary’s requirements,
      notifies the Trustee in writing that it elects to cause the issuance of the Definitive Notes; provided that in no event shall the Regulation S Temporary Global Note be exchanged by the Company for Definitive Notes prior to (A) the expiration
      of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; or

   

  (3) there has occurred and is continuing a Default or Event of Default with
      respect to the Notes, and the Depositary notifies the Trustee of its decision to exchange the Global Notes for Definitive Notes.

   

  Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive
      Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange
      for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another
      Note other than as provided in this Section 2.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (e) hereof.

   

  (b)    Transfer and Exchange of
        Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures.
      Participants and Indirect Participants shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or by the Trustee as the Custodian with respect to the Global Notes, and the Company, the Trustee
      and any agent of the Company or the Trustee shall be entitled to treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any
      agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants or the Indirect Participants, the operation of
      customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Note. Subject to the provisions of this Section 2.06 and Section 12.16, the Holder of a Global Note shall be entitled to
      grant proxies and otherwise authorize any Person, including Participants and Indirect Participants and Persons that may hold interests through such Persons, to take any action that a Holder is entitled to take under this Indenture or the Notes.
      Beneficial interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Except for the transfer of beneficial interests in the Regulation S
      Temporary Global Note for beneficial interests in the Regulation S Permanent Global Note as provided in Section 2.01(c), transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as

      Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private
      Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a U.S.
      Person (other than an Initial Purchaser). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or
      instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1).

   

  (2) All Other Transfers and Exchanges of Beneficial Interests in Global
        Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to either Section 2.06(b)(1) above or Section 2.06(e) below, the transferor of such beneficial interest must deliver to the Registrar either:

   

  (A)  both:

      in an amount equal to the beneficial interest to be transferred or exchanged; and

   

  (ii)    instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase; or

   

  (B)  both:

   

  (i)      a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial
      interest to be transferred or exchanged; and

   

  (ii)    instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in clause (i) above.

   

  provided that in no event shall Definitive Notes be issued upon the
      transfer or exchange of beneficial interests in the Regulation S Temporary Global Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the
      Securities Act.

   

  Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes

      receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If
      required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that
      any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

   

  Every replacement Note is an additional obligation of the Company and will be entitled to
      all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

   

  Section 2.08            Outstanding Notes.

   

  The Notes outstanding at any time are all the Notes authenticated by the Trustee except
      for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except
      as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding
      for purposes of Section 3.07(a) hereof.

   

  
    41 

    
      
 

  

   

  If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless
      the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

   

  If the principal amount of any Note is considered paid under Section 4.01 hereof, it
      ceases to be outstanding and interest on it ceases to accrue.

   

  If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof)
      holds, by 11:00 a.m., Eastern Time, on a Redemption Date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

   

  Section 2.09            Treasury Notes.

   

  In determining whether the Holders of the required principal amount of Notes have
      concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be
      considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so
      owned will be so disregarded.

   

  Section 2.10            Temporary Notes.

   

  Until certificates representing Notes are ready for delivery, the Company may prepare and
      the Trustee, upon receipt of an Authentication Order, together with the other documents required by Sections 12.03 and 12.04, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have
      variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for
      temporary Notes.

   

  Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

   

  Section 2.11            Cancellation.

   

  The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar
      and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement
      or cancellation and will destroy canceled Notes in accordance with the Trustee’s policy then in effect (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the
      Company upon written request. The Company may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

   

  Section 2.12            Defaulted Interest.

   

  If the Company defaults in a payment of interest on the Notes, they will pay the
      defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01
      hereof, provided that no special record date shall be required with respect to a payment of interest that is made within the applicable grace period. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be
      paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment
      date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will send or cause to be sent to Holders a notice
      that states the special record date, the related payment date and the amount of such interest to be paid. The Trustee will not at any time be under any duty or responsibility to any Holder of Notes to determine 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 defaulted interest.

   

  
    42 

    
      
 

  

   

  Section 2.13            Trustee, Paying Agent, Registrar Not Responsible for Depositary

   

  None of the Trustee, any Paying Agent or the Registrar shall have any responsibility or
      liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in any Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. The
      Trustee, any Paying Agent and the Registrar shall be entitled to deal with any Depositary, and any nominee thereof, that is the Holder of any Global Note for all purposes of this Indenture relating to such Global Note (including the payment of
      principal, premium, if any, and interest, the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Note) as the sole Holder of such Global Note and shall have no obligations to the
      beneficial owners thereof. None of the Trustee, any Paying Agent or the Registrar shall have any responsibility or liability for any acts or omissions of any Depositary with respect to any Global Notes, for the records of any Depositary, including
      records in respect of beneficial ownership interests in respect of any Global Note, for any transactions between such Depositary and any participant in such Depositary or between or among any such Depositary, any such participant or any holder or
      owner of a beneficial interest in any Global Note or for any transfers of beneficial interests in any Global Note.

   

  Section 2.14            Interest Rate Step Up

   

  From and including the interest payment period ending on October 1, 2023 (the “Interest




        Rate Step Up Trigger Date”), the interest rate payable solely on the Notes shall be increased once by 25 basis points to 7.875% per annum (the “Subsequent Rate of Interest”) unless the Company has notified (the “Satisfaction
        Notification”) the Trustee by delivery of an Officers’ Certificate at least 30 days prior to the Interest Rate Step Up Trigger Date (the “Notification Date”) that in respect of the year ended December 31, 2022 (the “Observation Period”):




      (i) the Sustainability Performance Target has been satisfied and (ii) the satisfaction of the Sustainability Performance Target has been confirmed by the External Verifier in accordance with customary procedures. If, as of the Notification Date, (x)
      the Company fails, or is unable, to provide the Satisfaction Notification, (y) the Sustainability Performance Target has not been satisfied or (z) the External Verifier has not confirmed satisfaction of the Sustainability Performance Target, the
      Subsequent Rate of Interest will apply from and including the first day of the interest rate period ending on the Interest Rate Step Up Trigger Date up to, and including, the maturity date of the Notes. The Trustee may conclusively rely on the
      Officers’ Certificate delivered by the Company with respect to the Satisfaction Notification and shall have no duty to monitor or confirm the Company’s satisfaction of the Sustainability Performance Target.

   

  ARTICLE 3

      REDEMPTION AND PREPAYMENT

   

  Section 3.01            Notices to Trustee.

   

  If the Company elects to redeem Notes pursuant to the optional redemption provisions of
      Section 3.07 or 4.13(d) hereof, they must furnish to the Trustee, at least five Business Days (unless a shorter period is satisfactory to the Trustee) before a notice of such redemption is to be given pursuant to Section 3.03, written notice setting
      forth:

   

  (1) the clause of this Indenture pursuant to which the redemption shall occur;

   

  
    43 

    
      
 

  

   

  (2) the Redemption Date;

   

  (3) the principal amount of Notes to be redeemed; and

   

  (4) the redemption price (if then determinable and otherwise the method of
      determination).

   

  Section 3.02            Selection of Notes to Be Redeemed.

   

  If less than all of the Notes are to be redeemed at any time, the Trustee will select
      Notes for redemption as follows:

   

  (1)    if the Notes are listed on any
      national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or

   

  		(2)	if the Notes are not listed on any national securities exchange, on a pro rata basis;


   

  and if the Notes are in global form, all in accordance with the procedures of the
      Depositary.

   

  No Notes of $2,000 or less can be redeemed in part. In the event of partial redemption,
      the particular Notes to be redeemed will be selected, unless otherwise provided herein, not less than 15 nor more than 60 days prior to the redemption by the Trustee from the outstanding Notes not previously called for redemption.

   

  The Trustee will promptly notify the Company in writing of the Notes selected for
      redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all
      of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to
      Notes called for redemption also apply to portions of Notes called for redemption.

   

  The Company will promptly notify the Trustee in writing of any listing or delisting of
      the Notes on or from a national securities exchange.

   

  Section 3.03            Notice of Redemption.

   

  At least 15 days but not more than 60 days before a Redemption Date, the Company will
      mail or cause to be mailed, by first class mail (or sent electronically in the case of notices to DTC) a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be given more
      than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or 11 hereof. Notice of any redemption of the Notes (including upon
      an Equity Offering or in connection with a transaction (or series of related transactions) that constitute a Change of Control) may, at the Company’s discretion, be given prior to the completion thereof and be subject to one or more conditions
      precedent, including, but not limited to, completion of the related Equity Offering or Change of Control. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s
      discretion, the Redemption Date may be delayed until such time (including more than 60 days after the date the notice of redemption was delivered) as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may
      be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date so delayed, or such notice may be rescinded at any time in the Company’s discretion if in the good faith
      judgment of the Company any or all of such conditions will not be satisfied. The Company shall provide written notice to the Trustee no later than the Redemption Date that all conditions to the redemption have been satisfied or if any such redemption
      has been rescinded or delayed, and upon receipt the Trustee shall provide such notice to each Holder of Notes in the same manner in which the redemption notice was given.

   

  
    44 

    
      
 

  

   

  The notice will identify the Notes to be redeemed and will state:

   

  (1) the Redemption Date;

   

  (2) the redemption price, if then determinable and, if not, the manner of its
      determination;

   

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

   

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

   

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

   

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

   

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

   

  (8) any condition precedent to the redemption; and

   

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

   

  At the Company’s request, the Trustee will give the notice of redemption in the Company’s
      name and at its expense; provided, however, that the Company has delivered to the Trustee written notice in accordance with Section 3.01 requesting that the Trustee give such notice and a form of the notice of redemption setting forth the
      information specified in the preceding paragraph.

   

  Section 3.04            Effect of Notice of Redemption.

   

  Once notice of redemption is given in accordance with Section 3.03 hereof, Notes called
      for redemption without condition will become irrevocably due and payable on the Redemption Date at the redemption price.

   

  Section 3.05            Deposit of Redemption Price.

   

  Prior to 11:00 a.m., Eastern Time, on the redemption date, the Company will deposit with
      the Trustee or with the Paying Agent money sufficient (as determined by the Company) to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent will promptly return to the Company any
      money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on all Notes to be redeemed.

   

  
    45 

    
      
 

  

   

  If the Company complies with the provisions of the preceding paragraph, on and after the
      redemption date, interest will cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid
      interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption is not so paid upon surrender for redemption because of the failure of the Company to comply
      with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate then in effect
      as provided in the Notes and in Section 4.01 hereof.

   

  Section 3.06            Notes Redeemed in Part.

   

  Upon surrender of a Note that is redeemed in part, the Company will issue and, upon
      receipt of an Authentication Order, the Trustee will authenticate for the Holder, at the expense of the Company, a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

   

  Section 3.07            Optional Redemption.

   

  (a)    At any time prior to April 1,
      2023, the Company may on any one or more occasions redeem up to 40% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture, upon prior notice in accordance with Section 3.03 hereof, (i) if the Company
      delivers to the Trustee an Officers’ Certificate, upon which the Trustee can conclusively rely without any duty or inquiry, certifying that the Company reasonably expects to satisfy the Sustainability Performance Target in respect of the Observation
      Period, at a redemption price of 107.625% of the principal amount and (ii) if the Company fails to deliver to the Trustee an Officers’ Certificate certifying that the Company reasonably expects to satisfy the Sustainability Performance Target in
      respect of the Observation Period, at a redemption price of 107.875% of the principal amount thereof, in each case, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of Notes on the
      relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings; provided that:

   

  (1) at least 60% of the aggregate principal amount of Notes issued under this
      Indenture on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

   

  (2) the redemption occurs within 180 days of the date of the closing of such
      Equity Offering.

   

  (b)    Except pursuant to Section
      3.07(a), Section 3.07(d), and Section 4.13(d) hereof, the Notes will not be redeemable at the Company’s option prior to April 1, 2023.

   

  (c)    On or after April 1, 2023, the
      Company may redeem all or a part of the Notes, upon prior notice in accordance with Section 3.03 hereof, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, on the Notes
      redeemed to, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on April 1 of each year indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest due on
      an interest payment date that is on or prior to the Redemption Date:

   

  
    46 

    
      
 

  

   

  	Year	Redemption Price (if the Sustainability Performance Target has been satisfied and the Company
              has provided the Satisfaction Notice to the Trustee)	
          Redemption Price (if the Sustainability Performance Target has 

          not been satisfied and/or the Company has not provided the Satisfaction Notice to the Trustee)

        
	Percentage	 
	2023 	103.8125%	103.9375%	 
	2024 	101.9063%	101.9688%	 
	2025 	  100.0000%	100.0000%	 


   

  (d)    At any time prior to April 1,
      2023, the Company may also redeem all or a part of the Notes, upon prior notice in accordance with Section 3.03 hereof, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and
      unpaid interest, if any, to, but excluding, the Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date. The notice need not set
      forth the Applicable Premium but only the manner of calculation of the redemption price. With respect to any redemption pursuant to this Section 3.07(d), the Company will (i) calculate the Treasury Rate on the second Business Day preceding the
      applicable Redemption Date and (ii) prior to such Redemption Date file with the Trustee an Officers’ Certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable detail. The Trustee shall
      not be responsible for any such calculation.

   

  (e)    Any redemption pursuant to this
      Section 3.07 or Section 4.13(d) shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

   

  Section 3.08            Mandatory Redemption.

   

  The Company is not required to make mandatory redemption or sinking fund payments with
      respect to the Notes. The Company is not prohibited from acquiring the Notes by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of this
      Indenture.

   

  Section 3.09            Offer to Purchase by Application of Excess Proceeds.

   

  In the event that, pursuant to Section 4.10 hereof, the Company is required to commence
      an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures specified below.

   

  The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness
      that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at
      least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the
      Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than
      the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

   

  If the Purchase Date is on or after an interest record date and on or before the related
      interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the
      Asset Sale Offer.

   

  
    47 

    
      
 

  

   

  Upon the commencement of an Asset Sale Offer, the Company will send, in the manner
      prescribed in Section 12.02, a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the
      terms of the Asset Sale Offer, will state:

   

  (1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and
      Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

   

  (2) the Offer Amount, the purchase price and the Purchase Date;

   

  (3) that any Note not tendered or accepted for payment will continue to accrue
      interest;

   

  (4) that, unless the Company defaults in making such payment, any Note accepted
      for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

   

  (5) that Holders electing to have a Note purchased pursuant to an Asset Sale
      Offer may elect to have Notes purchased in integral multiples of $1,000 only;

   

  (6) that Holders electing to have Notes purchased pursuant to any Asset Sale
      Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying
      Agent at the address specified in the notice at least three days before the Purchase Date;

   

  (7) that Holders will be entitled to withdraw their election if the Company,
      the depositary for the Asset Sale Offer or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, electronic image scan, facsimile transmission or letter setting forth the name of the
      Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

   

  (8) that, if the aggregate principal amount of Notes and other pari passu
      Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Notes and other pari passu Indebtedness to be purchased will be selected on a pro rata basis based on the principal amount of Notes and such other pari
        passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, will be purchased); and

   

  (9) that Holders whose Notes were purchased only in part will be issued new
      Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

   

  On or before the Purchase Date, the Company will, to the extent lawful, accept for
      payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause
      to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the
      depositary for the Asset Sale Offer or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes
      tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry)
      such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the
      results of the Asset Sale Offer on the Purchase Date.

  ARTICLE 4

      COVENANTS

   

  Section 4.01            Payment of Notes.

   

  The Company will pay or cause to be paid the principal of, premium, if any, and interest
      on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11:00 a.m. Eastern
      Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. With respect to physical certificates, presentation is due at maturity.

   

  The Company shall pay interest on overdue principal, and they shall pay interest on
      overdue installments of interest, at the rate then prevailing on the Notes to the extent lawful.

   

  Notwithstanding anything to the contrary contained in this Indenture, the Company may, to
      the extent required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments hereunder.

   

  Section 4.02            Maintenance of Office or Agency.

   

  The Company will maintain in the City of New York an office or agency (which may be an
      office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this
      Indenture may be served. The Company 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 Company fails to maintain any such required office or agency or fails to
      furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands (not including service of process) may be made or served at the Corporate Trust Office of the Trustee.

   

  The Company may also from time to time designate one or more other offices or agencies
      where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its
      obligation to maintain an office or agency in the City of New York for such purposes. The Company 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.

   

  The Company hereby designates the Corporate Trust Office of the Trustee as one such
      office or agency of the Company in accordance with Section 2.03 hereof.

      occurrence of any of the following events, a current report that contains a brief summary of the material terms, facts and/or circumstances involved to the extent not otherwise publicly disclosed: (i) entry by the Company or a Restricted Subsidiary
      into an agreement outside the ordinary course of business that is material (as determined by the Company in its sole discretion) to the Company and its Subsidiaries, taken as a whole, any material amendment thereto or termination of any such

  (b)    Notwithstanding the foregoing,
      (1) the financial statements, information and other documents required to be provided as described in Section 4.03(a) may be those of (i) the Company or (ii) IPOCo or any other direct or indirect parent of the Company; provided that in the
      case of clause (ii), if and so long as such direct or indirect parent of the Company has independent assets or operations, the same is accompanied by consolidating information (which need not be audited) that summarizes the difference between the
      information relating to such parent, on the one hand, and the information relating to the Company and its Restricted Subsidiaries on a stand-alone basis, on the other hand and (2) the above requirements may be satisfied by the filing with the SEC for
      public availability by the Company, IPOCo, or such direct or indirect parent of the Company, as the case may be, of any Annual Report on Form 10-K, Quarterly Report on Form 10-Q or Current Report on Form 8-K.

      such information provided pursuant to Section 4.03(a) will not be required to contain the separate financial information required by Rule 3-09, Rule 3-10 or Rule 3-16 of Regulation S-X or any schedules required by Regulation S-X, or in each case any

  (d)    If the Company has designated any
      of its Subsidiaries as an Unrestricted Subsidiary and if any such Unrestricted Subsidiary or group of Unrestricted Subsidiaries, if taken together as one Subsidiary, would constitute a Significant Subsidiary of the Company, then the annual and
      quarterly information required by Sections 4.03(a)(1) and 4.03(a)(2) shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, of the financial condition and results of operations of
      the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of such Unrestricted Subsidiaries.

   

  (e)    While IPOCo is in registration
      with respect to a Qualified IPO, the Company will not be required to disclose any information or take any actions that, in the view of the Company, would violate the securities laws or the SEC’s “gun jumping” rules or otherwise have an adverse effect
      on the Qualified IPO.

      of Default arising from a failure to furnish in a timely manner any information required by this Section 4.03 shall be deemed cured (and the Company shall be deemed to be in compliance with this Section 4.03) upon furnishing such information as
      contemplated by this Section 4.03 (but without regard to the date on which such information or report is so furnished); provided that such cure shall not otherwise affect the rights of the Holders under Article 6 if the principal of,
      premium, if any, on, and interest, if any, on, the Notes have been accelerated in accordance with the terms of this Indenture and such acceleration has not been rescinded or cancelled prior to such cure.

   

  (g)    The Company will hold and
      participate in conference calls with the Holders of the Notes, Beneficial Owners of the Notes, bona fide prospective investors, securities analysts and market makers with respect to the financial information required to be furnished pursuant to
      Sections 4.03(a)(1) and 4.03(a)(2) no later than ten business days after distribution of such financial information, unless, in each case, the Company reasonably determines that to do so would conflict with applicable securities laws, including in
      connection with any pending offering of securities. The Company shall be permitted to combine this conference call with any other conference call for other debt or equity holders or lenders. The Company shall, no later than three business days prior
      to the date of the conference calls required to be held in accordance with this Section 4.03(g), announce the date and time of such conference calls and all information necessary to enable Holders of Notes and security analysts to obtain access to
      such calls.

   

  (h)    So long as any Notes are
      outstanding, the Company will also maintain a website to which Holders, prospective investors, broker-dealers and securities analysts are given access (which may be password protected) and to which all of the reports required by this Section 4.03 are
      posted, unless they are otherwise publicly available on the SEC’s EDGAR filing system (or any successor filing system), and the posting of such reports to such website the availability of the shall satisfy the above reporting requirements.

      Holders, prospective investors, broker-dealers and securities analysts, upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the
      Securities Act.

  (j)      Delivery of reports,
      information and documents to the Trustee under this Indenture is for information purposes only and the information and the Trustee’s receipt of the foregoing shall not constitute actual or constructive knowledge or notice of any information contained
      therein, or determinable from information contained therein, including the Company’s compliance with any of its covenants thereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate). The Trustee shall have no duty
      to monitor or confirm, on a continuing basis or otherwise, the Company’s or any other person’s compliance with any of the covenants under this Indenture, to determine whether such reports, information or documents are available on the SEC’s EDGAR
      filing system (or any successor filing system), the Company’s website or otherwise, to examine such reports, information, documents and other reports to ensure compliance with the provisions of this Indenture, to ascertain the correctness or
      otherwise of the information or the statements contained therein or to participate in any conference calls

      year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled their obligations under this Indenture, and further stating, as to each such Officer signing

      respect thereto).

   

  (b)    So long as any of the Notes are
      outstanding, the Company and the Guarantors will deliver to the Trustee, within 30 days of an Officer thereof becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the
      Company is taking or propose to take with respect thereto.

   

  The Trustee shall be entitled to conclusively rely upon all of the Officers’ Certificates
      delivered under this Section 4.04 without any duty of further inquiry.

   

  Section 4.05            Taxes.

   

  The Company will pay, and will cause each of its Restricted Subsidiaries to pay, prior to
      delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the
      Notes.

      the performance of this Indenture; and the Company and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenants that they will not, by resort to any such law,
      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 has been enacted.

      date on which such irrevocable notice is delivered, such dividend, distribution or redemption would have complied with the provisions of this Indenture (assuming, in the case of a redemption payment, the giving of the notice of such redemption
      payment would have been deemed to be a Restricted Payment at such time and such deemed Restricted Payment would have been permitted at such time);

   

  (2) the making of any Restricted Payment in exchange for, or out of the net
      cash proceeds of, a substantially concurrent (a) capital contribution to the Company from any Person (other than a Restricted Subsidiary of the Company) or (b) sale (other than to a Restricted Subsidiary of the Company) of Equity Interests (other

      successive calendar years and added to such amount; provided further, that such amount in any twelve-month period may be increased by an amount not to exceed (a) the cash proceeds received by the Company from the sale of Equity Interests of
      the Company to members of management, employees, directors or managers of the Company or its Restricted Subsidiaries that occurs after the Issue Date (to the extent the cash proceeds from the sale of such Equity Interests have not otherwise been

      encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness

      Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Equity and will not permit any of its Restricted Subsidiaries to issue any Disqualified Equity; provided, however, that the Company and any
      Restricted Subsidiary may incur Indebtedness (including Acquired Debt) and the Company and the Restricted Subsidiaries may issue Disqualified Equity, if the Fixed Charge Coverage Ratio for the Company’s Reference Period immediately preceding the date
      on which such additional Indebtedness is incurred or such Disqualified Equity is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if
      the additional Indebtedness had been incurred or the Disqualified Equity had been issued, as the case may be, at the beginning of such Reference Period.

   

  (b)    The provisions of Section 4.09(a)
      hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”) or the issuance of any Disqualified Equity described in clause (11) below:

   

  (1) the incurrence by the Company or any of its Restricted Subsidiaries of
      additional Indebtedness and letters of credit and the Guarantees thereof under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal
      to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (a) $200.0 million and (b) the sum of $25.0 million and 30.0% of Consolidated Net Tangible Assets (determined as of the date of
      incurrence and after giving effect to the use of proceeds therefrom);

   

  (2) the incurrence by the Company and its Restricted Subsidiaries of any
      Existing Indebtedness;

   

  (3) the incurrence by the Company and the Guarantors of Indebtedness
      represented by the Notes and the related Note Guarantees issued on the Issue Date;

   

  (4) the incurrence by the Company or any of its Restricted Subsidiaries of
      Indebtedness represented by Finance Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property,
      plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any
      Indebtedness incurred pursuant to this clause (4), at any time outstanding not to exceed the greater of (a) $20.0 million and (b) 3.0% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of
      proceeds therefrom);

   

  (5) the incurrence by the Company or any of its Restricted Subsidiaries of
      Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be
      incurred under Section 4.09(a) hereof or clause (2), (3), (4), (10) or (14) of this Section 4.09(b) or this clause (5);

   

  
    58 

    
      
 

  

   

  (6) the incurrence by the Company or any of its Restricted Subsidiaries of
      intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

   

  (A)  if the Company or any Guarantor is the
      obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of
      the Company, or the Note Guarantee, in the case of a Guarantor; and

   

  (B)   (1) any subsequent issuance or
      transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (2) any sale or other transfer of any such Indebtedness to a Person that is not either the
      Company or a Restricted Subsidiary of the Company,

   

  will be deemed, in each case, to constitute an incurrence of such Indebtedness by
      Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

   

  (7) the incurrence by the Company or any of its Restricted Subsidiaries of
      Hedging Obligations or Indebtedness under Treasury Management Arrangements;

   

  (8) the Guarantee by the Company, or any of its Restricted Subsidiaries of (a)
      Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Section 4.09 or (b) Indebtedness incurred by Joint Ventures, provided that such Guarantee constitutes a
      Permitted Investment; and provided further, in each case, that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes or the Note Guarantees, then the Guarantee shall be subordinated or pari passu,
      as applicable, to the same extent as the Indebtedness Guaranteed;

   

  (9) the incurrence by the Company or any of its Restricted Subsidiaries of
      Indebtedness in respect of workers’ compensation claims, health or other types of social security benefits, unemployment or other insurance or self-insurance obligations, insurance contracts, reclamation, statutory obligations, bankers’ acceptances,
      and performance, payment, appeal and surety bonds in the ordinary course of business, including Guarantees and obligations respecting standby letters of credit supporting such obligations, to the extent not drawn (in each case other than an
      obligation for money borrowed) and replacements of any of the foregoing;

   

  (10) the incurrence by the Company or any of its Restricted Subsidiaries of
      Permitted Acquisition Indebtedness;

   

  (11) the issuance by the Company or any of its Restricted Subsidiaries of
      Disqualified Equity to the Company or any of its Restricted Subsidiaries, as the case may be; provided, however, that:

   

  (A)  any subsequent issuance or transfer of
      Equity Interests of a Restricted Subsidiary that results in any such Disqualified Equity being held, directly or indirectly, by a Person other than the Company or a Restricted Subsidiary of the Company; and

   

  (B)  any sale or other transfer of any such
      Disqualified Equity to a Person that is not either the Company or a Restricted Subsidiary of the Company;

   

  
    59 

    
      
 

  

   

  will be deemed, in each case, to constitute an issuance of such Disqualified Equity by the Company
      or such Restricted Subsidiary that was not permitted by this clause;

   

  (12) the incurrence in the ordinary course of business by the Company or any of
      its Restricted Subsidiaries of Indebtedness under letters of credit incurred pursuant to a Credit Facility, provided that such obligations are reimbursed within 10 days following the drawing of such letter of credit;

   

  (13) the incurrence by the Company or any of its Restricted Subsidiaries of
      liability in respect of the Indebtedness of any Unrestricted Subsidiary of the Company or any Joint Venture but only to the extent that such liability is the result of the Company’s or any such Restricted Subsidiary’s being a general partner of such
      Unrestricted Subsidiary or Joint Venture and not as guarantor of such Indebtedness and provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (13) and then outstanding
      does not exceed $25.0 million; and

   

  (14) the incurrence by the Company or any of its Restricted Subsidiaries of
      additional Indebtedness in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (14) at any time
      outstanding not to exceed the greater of (a) $35.0 million and (b) 5.0% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds therefrom).

   

  The Company will not incur, and will not permit any Subsidiary Guarantor to incur, any
      Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to
      the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company or any such
      Subsidiary Guarantor solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis.

   

  For purposes of determining compliance with this Section 4.09, in the event that an item
      of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (14) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to classify
      such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the date on which
      Notes are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt.

   

  The accrual of interest, the accretion or amortization of original issue discount, the
      payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Equity
      in the form of additional shares or units of the same class of Disqualified Equity will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Equity for purposes of this Section 4.09; provided, in each such case,
      that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term. Notwithstanding any other provision of this Section 4.09, the maximum amount of
      Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

   

  
    60 

    
      
 

  

   

  The amount of any Indebtedness outstanding as of any date will be:

   

  (1) the accreted value of the Indebtedness, in the case of any Indebtedness
      issued with original issue discount;

   

  (2) the principal amount of the Indebtedness, in the case of any other
      Indebtedness; and

   

  (3) in respect of Indebtedness of another Person secured by a Lien on the
      assets of the specified Person, the lesser of:

   

  (A) the Fair Market Value of such assets at the date of determination; and

   

  (B) the amount of the Indebtedness of the other Person.

   

  For purposes of determining compliance with any U.S. dollar-denominated restriction on
      the incurrence of Indebtedness, the U.S. dollar equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in
      the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the
      applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long
      as the principal amount of such refinancing Indebtedness does not exceed (i) the principal amount of such Indebtedness being refinanced plus (ii) the aggregate amount of fees, underwriting discounts, premiums and other costs and expenses incurred in
      connection with such refinancing. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate
      applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing.

   

  Section 4.10            Asset Sales.

   

  The Company will not, and will not permit any of its Restricted Subsidiaries to,
      consummate an Asset Sale unless:

   

  (1) the Company (or the Restricted Subsidiary, as the case may be) receives
      consideration (including by way of relief from, or by any Person assuming responsibilities for, any liabilities, contingent or otherwise) at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued
      or sold or otherwise disposed of (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale and which shall give effect to the assumption by another Person of any liabilities as provided for in clause (2)(A))
      below; and

   

  (2) at least 75% of the consideration received in the Asset Sale by the Company
      or such Restricted Subsidiary, together with the consideration received in all other Asset Sales by the Company or any Restricted Subsidiary since the Issue Date (on a cumulative basis) is in the form of cash or Cash Equivalents. For purposes of this
      provision, each of the following shall be deemed to be cash:

   

  (A)  any liabilities, as shown on the
      Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantees) that are assumed, cancelled or
      otherwise forgiven by the transferee of any such assets pursuant to a written agreement that releases the Company or such Restricted Subsidiary from further liability;

   

  
    61 

    
      
 

  

   

  (B)  any securities, notes or other
      Obligations received by the Company or any such Restricted Subsidiary from such transferee that are within 180 days after the Asset Sale (subject to ordinary settlement periods), converted by the Company or such Restricted Subsidiary into cash, to
      the extent of the cash received in that conversion;

   

  (C)  any stock or assets of the kind
      referred to in clause (2) or (4) of the next succeeding paragraph;

   

  (D)  any Designated Non-cash Consideration
      received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value (as determined in good faith by the Company), taken together with all other Designated Non-cash Consideration received pursuant to
      this clause (D), not to exceed the greater of (i) $35.0 million and (ii) and 5.0% of the Company’s Consolidated Net Tangible Assets at the time of receipt (with the fair market value of each item of Designated Non-cash Consideration being measured at
      the time received and without giving effect to subsequent changes in value); and

   

  (E)   accounts receivable of a business
      retained by the Company or any of its Restricted Subsidiaries, as the case may be, following the sale of such business, provided such accounts receivable (i) are not past due more than 60 days and (ii) do not have a payment date greater than
      90 days from the date of the invoices creating such accounts receivable.

   

  Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or
      the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

   

  (1) to repay Senior Indebtedness of the Company or its Restricted Subsidiaries
      (or to make an offer to repurchase or redeem such Indebtedness, provided that such repurchase or redemption closes within 45 days after the end of such 365-day period);

   

  (2) to acquire all or substantially all of the properties or assets of, or any
      Capital Stock of, another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Company;

   

  (3) to make a capital expenditure in a Permitted Business; or

   

  (4) to acquire other assets that are not classified as current assets under
      GAAP and that are used or useful in a Permitted Business.

   

  The requirement in clause (2), (3) or (4) of the preceding paragraph shall be deemed to
      be satisfied in a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein if entered into by the Company or any of its Restricted Subsidiaries within the time period specified in the preceding
      paragraph and such Net Proceeds are subsequently applied in accordance with such contract within 180 days following the date such agreement is entered into.

   

  Pending the final application of any Net Proceeds, the Company or any Restricted
      Subsidiary may invest or utilize the Net Proceeds in any manner that is not prohibited by this Indenture.

   

  
    62 

    
      
 

  

   

  Any Net Proceeds from Asset Sales that are not applied or invested as provided in the
      second paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $20.0 million, within five business days thereof, the Company will make an Asset Sale Offer to all Holders of Notes
      and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the
      maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The Company may satisfy the foregoing obligations with respect to any Net Proceeds from an Asset Sale by making an
      Asset Sale Offer with respect to such Net Proceeds or equivalent amount prior to the time period that any amount required by this Indenture with respect to all or a part of the available Net Proceeds (the “Advance Portion”) in advance of being
      required to do so by this Indenture (an “Advance Offer”). The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If
      any Excess Proceeds (or in the case of an Advance Offer, the Advance Portion) remain(s) after consummation of an Asset Sale Offer, the Company (or any Restricted Subsidiary) may use those Excess Proceeds (or Advance Portion) for any purpose not
      otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds (or in the case of an Advance Offer, the Advance
      Portion), the Trustee shall (subject to the Depositary’s applicable procedures) select the Notes and the representative of such other pari passu Indebtedness will (subject to the Depositary’s applicable procedures) select such other pari
        passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer (or Advance Offer), the amount of Excess Proceeds (or the Advance Portion) will be reset at zero.

   

  The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and
      any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or
      regulations conflict with the provisions of Section 3.09 hereof or this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or
      this Section 4.10 by virtue of such compliance.

   

  Section 4.11            Transactions with Affiliates.

   

  (a)    The Company will not, and will
      not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction,
      contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company involving more than $5.0 million (each an “Affiliate Transaction”), unless:

   

  (1) the Affiliate Transaction is on terms that are no less favorable to the
      Company or the relevant Restricted Subsidiary than those that could have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Company, no comparable
      transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is fair to the Company or the relevant Restricted Subsidiary from a financial or commercial point of view; and

   

  (2) the Company delivers to the Trustee with respect to any Affiliate
      Transaction (or series of related Affiliate Transactions) involving aggregate consideration in excess of $25.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate
      Transaction complies with clause (1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company, if any.

   

  
    63 

    
      
 

  

   

  (b)    The following items will not be
      deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a) hereof:

   

  (1) reasonable fees and compensation paid to or for the benefit of any
      employee, officer or director of the Company, any of its Restricted Subsidiaries, and any employment agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its
      Restricted Subsidiaries existing on the Issue Date, or entered into thereafter in the ordinary course of business, and any indemnities or other transactions permitted or required by bylaw, statutory provisions or any of the foregoing agreements,
      plans or arrangements;

   

  (2) transactions between or among the Company or its Restricted Subsidiaries;

   

  (3) transactions with a Person (other than an Unrestricted Subsidiary of the
      Company) that is an Affiliate of the Company or IPOCo solely because the Company or IPOCo owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

   

  (4) any issuance or sale of Equity Interests (other than Disqualified Equity)
      of the Company to Affiliates of the Company;

   

  (5) Permitted Investments or Restricted Payments that do not violate Section
      4.07 hereof;

   

  (6) customary compensation, indemnification and other benefits made available
      to officers, directors or employees of the Company, a Restricted Subsidiary of the Company, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

   

  (7) in the case of gathering, processing, transporting, waste water treatment
      or other operational contracts, any such contracts are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Company or any Restricted Subsidiary and third parties,
      or are otherwise fair to the Company or any Restricted Subsidiary from a financial or commercial point of view, as determined in good faith by a majority of the disinterested members of the Board of Directors of the Company;

   

  (8) the existence of, or the performance by the Company or any Restricted
      Subsidiary of its obligations under the terms of, any agreements to which it is a party as of the date of the Offering Memorandum and any amendments thereto and any similar agreements which it may enter into thereafter; provided, however,
      that the existence of, or the performance by the Company or any Restricted Subsidiary of its obligations under, any future amendment to such agreements or under any such similar agreements shall only be permitted by this clause (8) to the extent that
      the terms of any such amendment or new agreement, taken as a whole, are not less favorable to the Holders in any material respect as determined in good faith by a majority of the disinterested members of the Board of Directors of the Company, if any;

   

  (9) if such Affiliate Transaction is with a Person in its capacity as a holder
      of Indebtedness or Equity Interests of the Company or any of its Restricted Subsidiaries, a transaction in which such Person is treated no more favorably than the other holders of such Indebtedness or Equity Interests;

   

  (10) (A) Guarantees by the Company or any of its Restricted Subsidiaries of the
      performance of obligations of Unrestricted Subsidiaries or Joint Ventures in the ordinary course of business, except for Guarantees of Indebtedness in respect of borrowed money, and (B) pledges by the Company or any Restricted Subsidiary of Capital
      Stock in Unrestricted Subsidiaries or Joint Ventures for the benefit of lenders or other creditors of Unrestricted Subsidiaries or Joint Ventures as contemplated by clause (13) of the definition of “Permitted Liens” so long as any such transaction
      described in this clause (B), if involving aggregate consideration in excess of $25.0 million, has been approved by a majority of the disinterested members of the Board of Directors of the Company, if any;

   

  
    64 

    
      
 

  

   

  (11) any transaction in which the Company or any of its Restricted
      Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point
      of view or that such transaction meets the requirements of Section 4.11(a)(1) hereof;

   

  (12) any transactions between the Company or any Restricted Subsidiary and any
      Person, a director of which is also a director of the Company or a Restricted Subsidiary, provided that such director abstains from voting as a director of the Company or the Restricted Subsidiary, as applicable, in connection with the
      approval of the transaction; and

   

  (13) any transactions with or among the Company, IPOCo, their respective
      Restricted Subsidiaries and the Qualified Owners in connection with the IPOCo Transactions and the Qualified IPO, the transactions relating thereto, and the payment of all reasonable and customary fees and expenses related thereto, including fees to
      the Qualified Owners and the customary and reasonable expenses of the Qualified Owners.

   

  Section 4.12            Liens.

   

  The Company will not, and will not permit any of its Restricted Subsidiaries to, create,
      incur, assume or otherwise cause or suffer to exist or become effective any Lien (an “Initial Lien”) of any kind (other than Permitted Liens) securing Indebtedness, upon any of their property or assets, now owned or hereafter acquired, unless
      the Notes or any Note Guarantee of such Restricted Subsidiary, as applicable, are secured on an equal and ratable basis with the Indebtedness so secured until such time as such Indebtedness is no longer secured by a Lien.

   

  Any Lien created for the benefit of Holders of the Notes pursuant to the preceding
      paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

   

  Section 4.13            Offer to Repurchase Upon Change of Control.

   

  (a)    Upon the occurrence of a Change
      of Control, the Company will make an offer (a “Change of Control Offer”) to each Holder of Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in
      cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment”), subject to the rights of
      Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of purchase. Within 30 days following any Change of Control, the Company will send a notice to each Holder, with a copy
      to the Trustee, describing the transaction or transactions that constitute the Change of Control and stating:

   

  (1) that the Change of Control Offer is being made pursuant to this Section
      4.13 and that all Notes tendered will be accepted for payment;

   

  
    65 

    
      
 

  

   

  (2) the purchase price and the purchase date, which shall be no earlier than 30
      days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”);

   

  (3) that any Note not tendered will continue to accrue interest;

   

  (4) that, unless the Company defaults in the payment of the Change of Control
      Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

   

  (5) that Holders electing to have any Notes purchased pursuant to a Change of
      Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior
      to the close of business on the third Business Day preceding the Change of Control Payment Date;

   

  (6) that Holders will be entitled to withdraw their election if the Paying
      Agent or depositary receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, electronic image scan, facsimile transmission or letter setting forth the name of the
      Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

   

  (7) that Holders whose Notes are being purchased only in part will be issued
      new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

   

  The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and
      any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws
      or regulations conflict with the provisions of this Section 4.13, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.13 by virtue of such
      compliance.

   

  (b)    On the Change of Control Payment
      Date, the Company will, to the extent lawful:

   

  (1) accept for payment all Notes or portions of Notes properly tendered
      pursuant to the Change of Control Offer;

   

  (2) deposit with the Paying Agent or depositary an amount equal to the Change
      of Control Payment in respect of all Notes or portions of Notes properly tendered; and

   

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

   

  The Paying Agent or depositary will promptly mail to each Holder of Notes properly
      tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, it will make such payment through the facilities of DTC), and the Trustee will promptly authenticate and mail (or cause to be transferred by book
      entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.
      The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

   

  
    66 

    
      
 

  

   

  The provisions described above that require the Company to make a Change of Control Offer
      following a Change of Control will be applicable whether or not any other provisions of this Indenture are applicable.

   

  (c)    Notwithstanding anything to the
      contrary in this Section 4.13, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the
      requirements set forth in this Section 4.13 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice of redemption has been given pursuant to Section 3.03 hereof, unless and until there is a default in
      payment of the applicable redemption price, or (3) in connection with or in contemplation of any Change of Control, the Company or a third party makes an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered and not
      withdrawn at a cash price equal to or higher than the Change of Control Payment and purchases all Notes properly tendered and not withdrawn under the Alternate Offer.

   

  (d)    In the event that Holders of not
      less than 90% of the aggregate principal amount of the outstanding Notes tender and do not withdraw such Notes in a Change of Control Offer or Alternate Offer and the Company (or the third party making the Change of Control Offer or Alternate Offer
      as provided above) purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company will have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant
      to the Change of Control Offer or Alternate Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid
      interest on the Notes that remain outstanding to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption
      Date).

   

  Section 4.14            Additional Guarantees.

   

  If, after the Issue Date, any Domestic Subsidiary of the Company that is not already a
      Guarantor incurs or Guarantees any other Indebtedness of the Company under a Credit Facility in an aggregate principal amount in excess of $5.0 million for any such Domestic Subsidiary (provided that all such Domestic Subsidiaries that are not
      Guarantors do not incur or Guarantee any Indebtedness of the Company under a Credit Facility in excess of $25.0 million in the aggregate), then that Subsidiary will become a Guarantor by executing and delivering to the Trustee a supplemental
      indenture substantially in the form of Exhibit E hereto within 30 Business Days of the date on which it Guaranteed such Indebtedness; provided that the preceding shall not apply to Subsidiaries of the Company that have been properly
      designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Domestic Subsidiary that was incurred pursuant to
      this Section 4.14 will be released in accordance with Section 10.05 hereof.

   

  Section 4.15            Designation of Restricted and Unrestricted Subsidiaries.

   

  The Board of Directors of the Company may designate any Restricted Subsidiary to be an
      Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted
      Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will either reduce the amount available for Restricted Payments under Section 4.07 hereof or qualify
      as a Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by the Company; provided that any designation will only be permitted if the Investment would be permitted at that time and if the
      Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

   

  
    67 

    
      
 

  

   

  Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be
      evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and
      was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture
      and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be
      in default of such covenant.

   

  The Board of Directors of the Company may at any time designate any Unrestricted
      Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted
      Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the Reference Period and (2) no Default
      or Event of Default would be in existence following such designation.

   

  Section 4.16            Termination of Covenants.

   

  (a)    If on any date following the
      Issue Date: (i) the Notes are rated an Investment Grade Rating by a Rating Agency, and (ii) no Default or Event of Default shall have occurred and be continuing then, upon the Company’s delivery of an Officers’ Certificate notifying the Trustee that
      the Notes are rated an Investment Grade Rating as of the date of such Officers’ Certificate (the “Termination Date”), the Company and its Restricted Subsidiaries will no longer be subject to the following provisions of this Indenture: (1)
      Section 4.07; (2) Section 4.08; (3) Section 4.09; (4) Section 4.10, (5) Section 4.11; (6) Section 4.14; (7) Section 4.15; and (8) clause 4 of Section 5.01(a). For the avoidance of doubt, such provisions of this Indenture may not be reinstated
      following the Termination Date.

   

  (b)    However, the Company and its
      Restricted Subsidiaries will remain subject to the other provisions of this Indenture, including : (1) Section 4.03; (2) Section 4.12 (with associated incurrence capacity as if the covenant described in Section 4.09 remained in effect); and (3)
      Section 5.01 (with the exception of clause (4) of Section 5.01(a)).

   

  (c)    The Company may not designate any
      of its Subsidiaries as Unrestricted Subsidiaries after the Termination Date.

   

  (d)    The Trustee will have no
      obligation to independently determine or verify if a Termination Date has occurred or to notify the Holders of the same. The Trustee may conclusively rely on all Officers’ Certificates delivered pursuant to this Section 4.16 without any duty of
      further inquiry.

      DEFAULTS AND REMEDIES

   

  Section 6.01            Events of Default.

   

  Each of the following is an “Event of Default”:

   

  (1) default for 30 days in the payment when due of interest with respect to the
      Notes;

      otherwise) of the principal of, or premium, if any, on, the Notes;

   

  (3) failure by the Company to make a Change of Control Offer or an Asset Sale
      Offer within the time periods set forth, or consummate a purchase of Notes when required pursuant to the terms described in Section 4.13 or Sections 3.09 and 4.10 or to comply with the provisions of Section 5.01 hereof;

   

  (4) failure by the Company for 180 days after written notice to the Company by
      the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding to comply with Section 4.03 (a “Reporting Default”);

   

  (5) failure by the Company for 60 days after written notice to the Company by

  (6) default under any mortgage, indenture or instrument under which there may
      be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by the Company or any of its Restricted Subsidiaries), whether
      such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default:

   

  (A)  is caused by a failure to pay
      principal of such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or

   

  (B)  results in the acceleration of such
      Indebtedness prior to its express maturity,

   

  and, in each case, the principal amount of any such Indebtedness, together with the principal amount
      of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $35.0 million or more, provided, however, that if, prior to any acceleration of the Notes, (i) any such
      Payment Default is cured or waived, (ii) any such acceleration is rescinded, or (iii) such Indebtedness is repaid, in each case, during the 30-day period commencing upon the end of any applicable grace period for such Payment Default or the
      occurrence of such acceleration, as applicable, any Event of Default caused by such Payment Default or acceleration shall automatically be rescinded, so long as such rescission does not conflict with any judgment, decree or applicable law;

   

  
    70 

    
      
 

  

   

  (7) failure by the Company or any of the Company’s Restricted Subsidiaries to
      pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $35.0 million, which judgments are not paid, discharged or stayed for a period of 60 days;

  (B)  appoints a custodian of the Company or
      any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of
      the Company or any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; or

   

  (C)  orders the liquidation of the Company
      or any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary;

   

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

   

  (10) except as permitted by this Indenture, any Note Guarantee is held in any

    71 

    
      
 

  

   

  Section 6.02            Acceleration.

   

  In the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof,
      with respect to the Company or any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, the principal of, and
      accrued and unpaid interest, if any, on, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate
      principal amount of the then outstanding Notes may declare all the principal of, and accrued and unpaid interest, if any, on, Notes to be due and payable immediately.

   

  Upon any such declaration, the unpaid principal of, and accrued and unpaid interest, if
      any, on, Notes shall become due and payable immediately.

   

  The Holders of a majority in aggregate principal amount of the then outstanding Notes by
      notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the
      payment of interest, or premium, if any, on, or the principal of, the Notes.

   

  Section 6.03            Other Remedies.

   

  If an Event of Default occurs and is continuing, the Trustee may pursue any available
      remedy to collect the payment of principal, premium and interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

   

  The Trustee may maintain a proceeding even if it does not possess any of the Notes or
      does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
      acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

   

  Section 6.04            Waiver of Past Defaults.

   

  Holders of a majority in aggregate principal amount of the then outstanding Notes by
      notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium or
      interest on the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences,
      including any related payment default that resulted from such acceleration. Upon any such waiver, and the payment of all amounts due the Trustee in connection with such Default, such Default shall cease to exist, and any Event of Default arising
      therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

   

  Section 6.05            Control by Majority.

   

  Holders of a majority in aggregate principal amount of the then outstanding Notes may
      direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or
      this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability (provided, however, that the Trustee shall be under no obligation to determine
      whether any action or inaction is unduly prejudicial to any Holder) and the Trustee has not been offered indemnity and security satisfactory to it against any loss, liability or expense.

   

  
    72 

    
      
 

  

   

  Section 6.06            Limitation on Suits.

   

  A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

   

  (1) such Holder gives to the Trustee written notice that an Event of Default is
      continuing;

   

  (2) Holders of at least 25% in aggregate principal amount of the then
      outstanding Notes make a written request to the Trustee to pursue the remedy;

   

  (3) such Holder or Holders offer and, if requested, provide to the Trustee
      security and/or indemnity satisfactory to the Trustee against any loss, liability or expense;

   

  (4) the Trustee does not comply with the request within 60 days after receipt
      of the request and the offer of security or indemnity; and

   

  (5) during such 60-day period, Holders of a majority in aggregate principal
      amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.

   

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

   

  Section 6.07            Rights of Holders of Notes to Receive Payment.

   

  Notwithstanding any other provision of this Indenture, the right of any Holder of a Note
      to receive payment of principal, premium and interest and on the Note, on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be amended in a
      manner adverse to such Holder without the consent of such Holder.

   

  Section 6.08            Collection Suit by Trustee.

   

  If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is
      continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and interest remaining unpaid on, the Notes and interest on overdue
      principal and, to the extent lawful, interest and 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.

   

  Section 6.09            Trustee May File Proofs of Claim.

   

  The Trustee is authorized to file such proofs of claim and other papers or documents as
      may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any
      judicial proceedings relative to the Company (or any other obligor upon the Notes), their creditors or their property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any
      such claims and any custodian 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 to 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 7.06 hereof. To the extent that the payment of any such
      compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof 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. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition
      affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

   

  
    73 

    
      
 

  

   

  Section 6.10            Priorities.

   

  If the Trustee collects any money pursuant to this Article 6, it shall pay out the money
      in the following order:

   

  First: to the Trustee, the Agents and the Custodian, and their
      respective agents and attorneys for any and all amounts due under this Indenture, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

   

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

   

  Third: to the Company or to such party as a court of competent
      jurisdiction shall direct.

   

  The Trustee may fix a record date and payment date for any payment to Holders of Notes
      pursuant to this Section 6.10.

   

  Section 6.11            Undertaking for Costs.

   

  In any suit for the enforcement of any right or remedy under this Indenture or in any
      suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess
      reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the
      Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

  Section 7.01            Duties of Trustee.

   

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

   

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

   

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

   

  
    74 

    
      
 

  

   

  (2) in the absence of willful misconduct on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine
      the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

   

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

   

  (1) this paragraph does not limit the effect of paragraph (b) of this Section
      7.01;

   

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

   

  (3) the Trustee will not be liable with respect to any action it takes or omits
      to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof.

   

  (d)   Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section 7.01.

   

  (e)    No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights and powers under this Indenture at the request of any
      Holders, unless such Holder has furnished to the Trustee security and indemnity satisfactory to the Trustee against any loss, liability or expense.

   

  (f)     The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent
      required by law.

   

  Section 7.02            Rights of Trustee.

   

  (a)    The Trustee may conclusively rely
      and shall be fully protected in acting or refraining from acting upon any document (whether in original or facsimile form or PDF transmission or executed or signed in accordance with Section 12.11 hereof) believed by it to be genuine and to have been
      signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

   

  (b)    Before the Trustee acts or
      refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel.
      Prior to taking, suffering or admitting any action, the Trustee may consult with counsel of the Trustee’s own choosing and the advice of such counsel or any Opinion of Counsel will 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 conclusive reliance thereon.

   

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

   

  
    75 

    
      
 

  

   

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

   

  (e)    Unless otherwise specifically
      provided in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company.

   

  (f)     The Trustee will 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 have furnished to the Trustee indemnity and/or security satisfactory to the Trustee against the
      losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

   

  (g)    The Trustee shall not be deemed
      to have notice of a Default or an Event of Default unless a Responsible Officer of the Trustee (i) receives written notice of such Default or Event of Default, and such notice references this Indenture and the Notes or otherwise (ii) has actual
      knowledge of such Default or Event of Default in connection with Sections 6.01(1) or 6.01(2).

   

  (h)    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 or such loss or damage
      and regardless of the form of action.

   

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

   

  (j)      Any discretion, permissive
      right or privilege in favor of the Trustee shall not be construed as a duty or obligation.

   

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

   

  (l)      The Trustee will 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
      documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to
      examine during normal business hours the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry or
      investigation.

   

  (m)  The Trustee may request that the
      Company and each of the Guarantors shall deliver to the Trustee an Officers’ Certificate setting forth the names of individuals and/or titles of Officers of the Company and each Guarantor, as applicable, authorized at such time to take specified
      actions pursuant to this Indenture of the Company, the Notes and the Guarantees, 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.

   

  Section 7.03            Individual Rights of Trustee.

   

  The Trustee in its individual or any other capacity may become the owner or pledgee of
      Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. The Trustee is also subject to Sections 7.08 and 7.09 hereof.

   

  
    76 

    
      
 

  

   

  Section 7.04            Trustee’s Disclaimer.

   

  The Trustee will not be responsible for and makes no representation as to the validity,
      adequacy or enforceability of this Indenture or the Notes, it shall not be liable for the acts or omissions of the Company or accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s
      direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any
      statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. The Trustee shall not be liable in its individual capacity for the Obligations evidenced
      by the Notes or this Indenture.

   

  Section 7.05            Notice of Defaults.

   

  If a Default or Event of Default occurs and is continuing and if it is actually known to
      a Responsible Officer of the Trustee in accordance with Section 7.02(g), the Trustee will send to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in
      payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

   

  Section 7.06            Compensation and Indemnity.

   

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

   

  (b)    The Company and the Guarantors
      will indemnify, defend and protect, jointly and severally, the Trustee (in its individual capacity and in any capacity under this Indenture and any other document or transaction entered into in connection herewith) and its agents and any
      authenticating agent for, and to hold them harmless against, any and all losses, liabilities, claims or expenses, including taxes (other than taxes based upon, or measured by or determined by the income of the Trustee) 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 (including reasonable fees, costs and expenses of its agents and counsel and court costs) of enforcing this Indenture against
      the Company and the Guarantors (including this Section 7.06) and defending itself against any claim (whether asserted by the Company, the Guarantors, 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 gross negligence or willful misconduct, as determined by a court of competent jurisdiction in a final, non-appealable decision. The
      Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor
      will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees, costs and expenses of such counsel. Neither the Company nor any Guarantor need pay for any
      settlement made without its consent, which consent will not be unreasonably withheld.

   

  
    77 

    
      
 

  

   

  (c)    The obligations of the Company
      and the Guarantors under this Section 7.06 will survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

   

  (d)    To secure the Company’s and the
      Guarantors’ payment obligations in this Section 7.06, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien
      will survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee or any termination of this Indenture including in connection with any bankruptcy proceeding of the Company and/or the Guarantors.

   

  (e)    When the Trustee incurs expenses
      or renders services after an Event of Default specified in Section 6.01(8) or (9) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of
      administration under any Bankruptcy Law.

   

  Section 7.07            Replacement of Trustee.

   

  (a)    A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.07.

   

  (b)   The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may, with 30 days prior
      written notice to the Trustee and the Company, remove the Trustee by so notifying the Trustee and the Company. The Company may remove the Trustee if:

   

  (1) the Trustee fails to comply with Section 7.09 hereof;

   

  (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief
      is entered with respect to the Trustee under any Bankruptcy Law;

      or

   

  (4) the Trustee becomes incapable of acting.

   

  (c)    If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a
      majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

   

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

   

  (e)    If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.09 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and
      the appointment of a successor Trustee.

   

  
    78 

    
      
 

  

   

  (f)     A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will
      have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor
      Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.06 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.07, the Company’s obligations under
      Section 7.06 hereof will continue and survive for the benefit of the retiring Trustee and will also survive the satisfaction and discharge of this Indenture and any termination of this Indenture including a termination in connection with bankruptcy
      of the Company and/or the Guarantors.

   

  Section 7.08            Successor Trustee by Merger, etc.

   

  If the Trustee consolidates, merges or converts into, or transfers all or substantially
      all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee.

   

  Section 7.09            Eligibility; Disqualification.

   

  There will at all times be a Trustee hereunder that is a corporation organized and doing
      business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a
      combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition.

   

  ARTICLE 8

      LEGAL DEFEASANCE AND COVENANT DEFEASANCE

   

  Section 8.01            Option to Effect Legal Defeasance or Covenant Defeasance.

   

  The Company may, at its option and at any time, elect to have either Section 8.02 or 8.03
      hereof be applied to all outstanding Notes and Note Guarantees upon compliance with the conditions set forth below in this Article 8.

   

  Section 8.02            Legal Defeasance and Discharge.

   

  Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this
      Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the
      Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire
      Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1)
      and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same),
      except for the following provisions which will survive until otherwise terminated or discharged hereunder:

   

  (1) the rights of Holders of outstanding Notes to receive payments in respect
      of the principal of, or interest or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

   

  
    79 

    
      
 

  

   

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

   

  (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder
      and the Company’s and the Guarantors’ obligations in connection therewith including, without limitation, those in Section 7.06 hereof; and

   

  (4) this Article 8.

   

  Subject to compliance with this Article 8, the Company may exercise its option under this
      Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

   

  Section 8.03            Covenant Defeasance.

   

  Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this
      Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07,
      4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes, and the Guarantors will be released from their Obligations with respect to the Note Guarantees, on and after the
      date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of
      Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes
      and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference
      elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01
      hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03,
      subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(7) inclusive and Section 6.01(10) hereof will not constitute Events of Default.

   

  Section 8.04            Conditions to Legal or Covenant Defeasance.

   

  In order to exercise either Legal Defeasance or Covenant Defeasance under either Section
      8.02 or 8.03 hereof:

   

  (1) the Company must irrevocably deposit with the Trustee, in trust, for the
      benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient (in the case of amounts including
      non-callable Government Securities), in the opinion of a nationally recognized investment bank or firm of independent public accountants, to pay the principal of, or interest and premium, if any, on the outstanding Notes on the stated date for
      payment thereof or on the applicable Redemption Date, as the case may be, and any all other amounts due under this Indenture, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular
      Redemption Date;

   

  
    80 

    
      
 

  

   

  (2) in the case of an election under Section 8.02 hereof, the Company must
      deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

   

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

   

  (B)  since the Issue Date, there has been a
      change in the applicable federal income tax law,

   

  in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the
      Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as
      would have been the case if such Legal Defeasance had not occurred;

   

  (3) in the case of an election under Section 8.03 hereof, the Company must
      deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and
      will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

   

  (4) no Default or Event of Default shall have occurred and be continuing on the
      date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness) or the grant of Liens securing such borrowings);

   

  (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or
      violation of, or constitute a default under, any material agreement or instrument (other than this Indenture or any other agreement governing other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Subsidiaries
      is a party or by which the Company or any of its Subsidiaries is bound;

   

  (6) the Company must deliver to the Trustee an Officers’ Certificate stating
      that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company; and

   

  (7) the Company must deliver to the Trustee an Officers’ Certificate and an
      Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

   

  Section 8.05            Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

   

  Subject to Section 8.06 hereof, all money and non-callable Government Securities
      (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust
      and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of
      such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest but such money need not be segregated from other funds except to the extent required by law.

   

  
    81 

    
      
 

  

   

  The Company will pay and indemnify the Trustee against any tax, fee or other charge
      imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the
      account of the Holders of the outstanding Notes.

   

  Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or
      pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants
      expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal
      Defeasance or Covenant Defeasance.

   

  Section 8.06            Repayment to the Company.

   

  Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
      trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall, subject to applicable escheatment laws, be
      paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such
      Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that, if any Definitive Note is then outstanding, the Trustee or such Paying Agent, before being
      required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified
      therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

   

  Section 8.07            Reinstatement.

   

  If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable
      Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s
      and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
      permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the
      reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

  (3) to provide for the assumption of the Company’s or a Guarantor’s obligations
      to the Holders of the Notes and Note Guarantees in the case of a merger or consolidation or disposition of all or substantially all of the Company’s or such Guarantors’ properties or assets, as applicable;

   

  (4) to make any change that would provide any additional rights or benefits to
      the Holders of the Notes or that does not adversely affect the legal rights hereunder of any such Holder;

   

  (5) to conform the text of this Indenture, the Notes or the Note Guarantees to
      any provision of the “Description of notes” section of the Company’s Offering Memorandum to the extent that such provision was intended to be a verbatim recitation of a provision of this Indenture, the Notes or the Note Guarantees;

   

  (6) to provide for the issuance of Additional Notes in accordance with the
      limitations set forth in this Indenture as of the Issue Date;

      a Note Guarantee with respect to the Notes or to reflect the release of a Note Guarantee in accordance with this Indenture;

  (11) to appoint a successor trustee.

   

  Upon the request of the Company, and upon receipt by the Trustee of the documents
      described in Section 9.05 hereof, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate
      agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

   

  Section 9.02            With Consent of Holders of Notes.

   

  Except as provided below in this Section 9.02, the Company, the Guarantors and the
      Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.13 hereof), the Notes and the Note Guarantees with the consent of the Holders of a majority in aggregate principal amount of the then outstanding
      Notes (including, without limitation, Additional Notes, if any), including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes, and, subject to Sections 6.04 and 6.07 hereof, any
      existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with
      any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any),
      including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes. Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.
      However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

   

  (1) reduce the principal amount of Notes whose Holders must consent to an
      amendment, supplement or waiver;

   

  
    83 

    
      
 

  

   

  (2) reduce the principal of or change the fixed maturity of any Note or alter
      the provisions with respect to the redemption or repurchase of the Notes (other than provisions relating to minimum required notice of optional redemption or the provisions of Sections 3.09 and 4.10 or Section 4.13 hereof);

   

  (3) reduce the rate of or change the time for payment of interest, including
      the Subsequent Rate of Interests or default interest on any Note (other than with respect to the minimum notice period required under Article 3);

   

  (4) waive a Default or Event of Default in the payment of principal of, or
      interest or premium, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such
      acceleration);

   

  (5) make any Note payable in money other than that stated in the Notes;

   

  (6) make any change in the provisions of this Indenture relating to waivers of
      past Defaults or the rights of Holders of Notes to receive payments of, principal of, or interest or premium, if any, on, the Notes (other than as permitted by clause (7) below);

   

  (7) waive a redemption or repurchase payment with respect to any Note (other
      than a payment required by Sections 3.09 and 4.10 or Section 4.13 hereof);

   

  (8) release any Guarantor from any of its obligations under its Note Guarantee
      or this Indenture, except in accordance with the terms of this Indenture; or

   

  (9) make any change in the preceding amendment, supplement and waiver
      provisions.

   

  Upon the request of the Company and upon the filing with the Trustee of evidence
      satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.05 hereof, the Trustee will join with the Company and the Guarantors in the execution of such
      amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be
      obligated to, enter into such amended or supplemental Indenture.

   

  It is not be necessary for the consent of the Holders of Notes under this Section 9.02 to
      approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

   

  After an amendment, supplement or waiver under this Section 9.02 becomes effective, the
      Company will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the
      validity of any such amended or supplemental indenture or waiver.

   

  
    84 

    
      
 

  

   

  Section 9.03            Revocation and Effect of Consents.

   

  Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder
      of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any
      such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver
      becomes effective in accordance with its terms (except as provided in the second succeeding paragraph) and thereafter binds every Holder.

   

  The Company may, but shall not be obligated to, fix a record date for the purpose of
      determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the second to last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date
      (or their duly designated proxies) and only those Persons, shall be entitled to consent to such amendment or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date.

   

  After an amendment, supplement or waiver becomes effective, it shall bind every Holder,
      unless it makes a change described in any of the clauses (1) through (9) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or
      portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

   

  Section 9.04            Notation on or Exchange of Notes.

   

  The Trustee may place an appropriate notation about an amendment, supplement or waiver on
      any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

   

  Failure to make the appropriate notation or issue a new Note will not affect the validity
      and effect of such amendment, supplement or waiver.

   

  Section 9.05            Trustee to Sign Amendments, etc.

   

  The Trustee will sign any amended or supplemental indenture authorized pursuant to this
      Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01
      hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.03 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or
      permitted by this Indenture and that such supplemental indenture constitutes the legal, valid and binding obligation of Company and the Guarantors subject to customary exceptions.

   

  Section 9.06            Effect of Supplemental Indentures.

   

  Upon the execution of any supplemental indenture under this Article 9, 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 Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

  ARTICLE 10

      NOTE GUARANTEES

   

  Section 10.01         Guarantee.

   

  (a)    Subject to this Article 10, each
      of the Guarantors hereby, jointly and severally, guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the
      Notes or the obligations of the Company hereunder or thereunder, that:

   

  (1) the principal of, premium, if any, and interest on, the Notes will be
      promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or
      the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

   

  (2) in case of any extension of time of payment or renewal of any Notes or any
      of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

   

  Failing payment when due of any amount so guaranteed or any performance so guaranteed for
      whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

   

  (b)    The Guarantors hereby agree that
      their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to
      any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor
      hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever
      and covenants that its Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

   

  (c)    If any Holder or the Trustee is
      required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such
      Holder, each Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

   

  (d)    Each Guarantor agrees that it
      will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on
      the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Section 10.01, notwithstanding any stay, injunction or
      other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and
      payable) will forthwith become due and payable by the Guarantors for the purposes of this Section 10.01. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the
      rights of the Holders under the Note Guarantee.

   

  
    86 

    
      
 

  

   

  Section 10.02         Limitation on Guarantor Liability.

   

  Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirm that it is
      the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
      federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum
      amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or
      payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or
      conveyance.

   

  Section 10.03         Execution and Delivery of Notation of Note Guarantee.

   

  To evidence its Note Guarantee and of all the Obligations under this Indenture set forth
      in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit D hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the
      Trustee (provided that no such notation will be required with respect to any Note authenticated prior to the time a Guarantor becomes a Guarantor) and that this Indenture (including any supplement thereto) will be executed on behalf of such Guarantor
      by one of its Officers.

   

  Each Guarantor hereby agrees that its Note Guarantee and its guarantee of all of the
      Obligations under this Indenture set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

   

  If an Officer whose signature is on this Indenture or on the notation of its Note
      Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such notation of its Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

   

  The delivery of any Note by the Trustee, after the authentication thereof hereunder, will
      constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors.

   

  In the event that the Company or any of the Company’s Restricted Subsidiaries creates or
      acquires any wholly-owned Domestic Subsidiary after the date of this Indenture, if required by Section 4.14 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.14 hereof and this Article 10, to the
      extent applicable.

   

  Section 10.04         Guarantors May Consolidate, etc., on Certain Terms.

   

  Except as otherwise provided in Section 10.05 hereof, a Guarantor may not sell or
      otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless:

   

  (a)    immediately after giving effect
      to such transaction, no Default or Event of Default exists; and

   

  
    87 

    
      
 

  

   

  (b)    either:

   

  (1) the Person acquiring the properties or assets in any such sale or
      disposition or the Person formed by or surviving any such consolidation or merger is a Guarantor, or assumes all the obligations of that Guarantor under this Indenture and its Note Guarantee, pursuant to a supplemental indenture in form reasonably
      satisfactory to the Trustee; or

   

  (2) the transaction does not violate Section 4.10 of this Indenture.

   

  In case of any such consolidation, merger, sale or other disposition and upon the
      assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of such obligations of the Guarantor, such successor Person will succeed to and be substituted
      for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the Notes issuable hereunder which
      theretofore shall not have been signed by the Company and delivered to the Trustee. The Note Guarantee so issued by such successor Person will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees
      theretofore and thereafter issued in accordance with the terms of this Indenture as though such Note Guarantee had been issued at the date of the execution hereof.

   

  Section 10.05         Releases.

   

  (a)       In the event of any sale or other disposition (i) of all or substantially all
      of the properties or assets of any Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the Company, or (ii) of all of
      the Capital Stock of any Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary of the Company, then such Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other
      Obligations under this Indenture; provided that any such sale or other disposition does not violate the applicable provisions of Section 4.10 hereof.

   

  (b)       Upon designation of any Guarantor as an Unrestricted Subsidiary in accordance
      with the terms of this Indenture, such Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other Obligations under this Indenture.

   

  (c)       At such time as such Guarantor ceases to guarantee any other Indebtedness of
      the Company under a Credit Facility such that it would not, if not a Guarantor, be required to become a Guarantor under Section 4.14 hereof, such Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other
      Obligations under this Indenture.

   

  (d)       Upon Legal Defeasance or Covenant Defeasance in accordance with Article 8
      hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof, each Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other Obligations under this Indenture.

   

  (e)       Upon the merger or consolidation of any Guarantor with and into the Company or
      another Guarantor that is the surviving Person in such merger or consolidation, or upon the liquidation or dissolution of such Guarantor, such Guarantor will be relieved of any obligations under its Note Guarantee and all of its other Obligations
      under this Indenture.

   

  (f)       Upon delivery by the Company to the Trustee of an Officers’ Certificate and an
      Opinion of Counsel to the effect that the conditions of this Section 10.05 for a release have been satisfied, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its
      Note Guarantee and all of its other Obligations under this Indenture.

   

  
    88 

    
      
 

  

   

  (g)       Any Guarantor not released from its obligations under its Note Guarantee and
      all of its other Obligations under this Indenture as provided in this Section 10.05 will remain liable for the full amount of principal of and interest, and premium, if any, on the Notes and for the other Obligations of such Guarantor under this
      Indenture as provided in this Article 10.

   

  ARTICLE 11

      satisfaction and discharge

   

  Section 11.01          Satisfaction and Discharge.

   

  This Indenture will be discharged and will cease to be of further effect as to all Notes
      issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified in this Article 11), when:

   

  (1) either:

   

  (A)  all Notes that have been
      authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

   

  (B)  all Notes that have not been delivered
      to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the sending of a notice of redemption or otherwise, and the Company or any Guarantor has irrevocably deposited or caused to be
      deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be
      sufficient, without consideration of any reinvestment of interest, in the opinion of a nationally recognized investment bank or firm of independent public accountants to the extent the deposit includes any Government Securities, to pay and discharge
      the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest, if any, to the date of Stated Maturity or redemption;

   

  (2) the Company or any Guarantor has paid or caused to be paid all sums payable
      by it under this Indenture, including without limitation any and all amounts due and owing to the Trustee; and

   

  (3) the Company has delivered irrevocable instructions to the Trustee under
      this Indenture to apply the deposited money toward the payment of the Notes at Stated Maturity or on the Redemption Date, as the case may be.

   

  In addition, the Company must deliver (a) an Officers’ Certificate stating that all conditions precedent set
      forth in clauses (1) through (3) above have been satisfied, and (b) an Opinion of Counsel to the Trustee (which Opinion of Counsel may be subject to customary assumptions and qualifications), stating that all conditions precedent to satisfaction and
      discharge set forth in Section 11.01(3) have been satisfied.

   

  Notwithstanding the satisfaction and discharge of this Indenture, if money has been
      deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of
      Section 7.06 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

   

  
    89 

    
      
 

  

   

  Section 11.02          Application of Trust Money.

   

  Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee
      pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent)
      as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the
      extent required by law.

   

  If the Trustee or Paying Agent is unable to apply any money or Government Securities in
      accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s
      obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with
      Section 11.01; provided that if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of their obligations, the Company shall be subrogated to the rights of the Holders of
      such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

   

  The Company will pay and indemnify the Trustee against any tax, fee or other charge
      imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 11.01 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the
      account of the Holders of the outstanding Notes.

  7.625% Senior Sustainability-Linked Notes due 2026

   

  Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

   

  (1) Interest. Solaris Midstream Holdings, LLC, a Delaware limited liability
    company (the “Company”), promises to pay interest on the unpaid principal amount of this Note at 7.625% per annum. The Company will pay interest semi-annually in arrears on April 1 and October 1 of each year, or if any such day is not a Business
    Day, on the next succeeding Business Day (each, an “Interest Payment Date”); provided that the first Interest Payment Date shall be October 1, 2021. Interest on the Notes will accrue from the most recent date to which interest has been
    paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next
    succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. If any payment with respect to any principal of, premium, if any,
    on, or interest, if any, on any Notes (including any payment to be made on any dated fixed for redemption or purchase of any Note) is due on a day which is not a Business Day, then the payment need not be made on such date, but may be made on the next
    Business Day with the same force and effect as if made on such date, and no interest will accrue for the intervening period.

   

  From and including the interest payment period ending on October 1, 2023 (the “Interest Rate Step Up Trigger Date”), the interest
    rate payable solely on the Notes shall be increased once by 25 basis points to 7.875% per annum (the “Subsequent Rate of Interest”) unless the Company has notified (the “Satisfaction Notification”) the Trustee in writing at least 30 days
    prior to the Interest Rate Step Up Trigger Date (the “Notification Date”) that in respect of the year ended December 31, 2022 (the “Observation Period”): (i) the Sustainability Performance Target has been satisfied and (ii) the
    satisfaction of the Sustainability Performance Target has been confirmed by the External Verifier in accordance with customary procedures. If, as of the Notification Date, (x) the Company fails, or is unable, to provide the Satisfaction Notification,
    (y) the Sustainability Performance Target has not been satisfied or (z) the External Verifier has not confirmed satisfaction of the Sustainability Performance Target, the Subsequent Rate of Interest will apply from and including the first day of the
    interest rate period ending on the Interest Rate Step Up Trigger Date up to, and including, the maturity date of the Notes.

   

  (2) Method of Payment. The Company will pay interest on the Notes (except
    defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such
    Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest at the office or agency of the Company maintained for such purpose within or
    without the City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of
    immediately available funds will be required with respect to principal of and interest and premium on, all Global Notes and all other Notes to Holders having an aggregate principal amount of Notes more than $5,000,000, the Holders of which will have
    provided wire transfer instructions not later than the relevant record date to the Company or the Paying Agent to that Holder’s U.S. dollar account within the United States. The Company will pay the principal of, and interest on, Notes in global form
    registered in the name of or held by The Depository Trust Company (“DTC”) or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such global notes. Such payment will be in such coin
    or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

   

  
    A-3

    
      
 

  

   

  (3) Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association,
    the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

   

  (4) Indenture. The Company issued the Notes under an Indenture dated as of April
    1, 2021 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such
    terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Company. The Indenture does not limit
    the aggregate principal amount of Notes that may be issued thereunder.

   

  (5) Optional Redemption.

   

  (a)    Except pursuant to paragraphs (b), (c) and (d) of
    this Section 5, the Notes will not be redeemable at the Company’s option prior to April 1, 2023. On or after April 1, 2023, the Company may redeem all or a part of the Notes, upon prior notice in accordance with Section 3.03 of the Indenture, at the
    redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on April 1
    of each year indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date:

   

  	Year	Redemption Price (if the Sustainability Performance Target has been satisfied and the Company has provided the
            Satisfaction Notice to the Trustee)	Redemption Price (if the Sustainability Performance Target has not been satisfied and/or the Company has not provided
            the Satisfaction Notice to the Trustee)
	Percentage
	2023 	103.8125%	103.9375%
	2024 	101.9063%	101.9688%
	2025 	 100.0000%	100.0000%


   

  (b)    Notwithstanding the provisions of subparagraph
    (a) of this Section 5, at any time prior to April 1, 2023, the Company may on any one or more occasions redeem, upon prior notice in accordance with Section 3.03 of the Indenture, up to 40% of the aggregate principal amount of Notes (including any
    Additional Notes) issued under this Indenture (i) if the Company delivers to the Trustee an Officers’ Certificate, upon which the Trustee can conclusively rely without any duty or inquiry, certifying that the Company reasonably expects to satisfy the
    Sustainability Performance Target in respect of the Observation Period, at a redemption price of 107.625% of the principal amount and (ii) if the Company fails to deliver to the Trustee an Officers’ Certificate certifying that the Company reasonably
    expects to satisfy the Sustainability Performance Target in respect of the Observation Period, at a redemption price of 107.875% of the principal amount thereof, in each case, plus accrued and unpaid interest to, but excluding, the Redemption Date
    (subject to the right of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date), with an amount of cash not greater than the net cash proceeds of one or more Equity
    Offerings; provided that at least 60% of the aggregate principal amount of Notes issued under this Indenture on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of
    such redemption; and the redemption occurs within 180 days of the date of the closing of such Equity Offering.

   

  
    A-4

    
      
 

  

   

  (c)    Notwithstanding the provisions of subparagraph
    (a) of this Section 5, at any time prior to April 1, 2023, the Company may also redeem all or a part of the Notes, upon prior notice in accordance with Section 3.03 of the Indenture, at a redemption price equal to 100% of the principal amount of Notes
    redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but excluding, the Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on prior to the
    Redemption Date.

   

  (d)    The Company may also redeem the Notes as provided
    in Section 4.13(d) of the Indenture, on the terms and subject to the conditions set forth therein.

   

  For purposes of this Paragraph 5, “Applicable Premium” means, with respect to any Note at the time of determination, the greater of: (1)
    100% of the principal amount of the Note to be redeemed; or (2) the present value at such time of (i) the redemption price of the Note at April 1, 2023, provided that if the Company shall deliver to the Trustee an Officers’ Certificate
    certifying that the Company reasonably expects to satisfy the Sustainability Performance Target in respect of the Observation Period, then such redemption price will set forth in the table appearing in Section 3.07(c) of the Indenture under “Redemption
    Price (if the Sustainability Performance Target has been satisfied and the Company has provided the Satisfaction Notice to the Trustee)”; provided further that the if the Company shall fail to deliver to the Trustee an Officers’ Certificate
    certifying that the Company reasonably expects to satisfy the Sustainability Performance Target in respect of the Observation Period, then such redemption price will set forth in the table appearing in Section 3.07(c) of the Indenture under “Redemption
    Price (if the Sustainability Performance Target has not been satisfied and/or the Company has not provided the Satisfaction Notice to the Trustee)” plus (ii) all required interest payments due on the Note through April 1, 2023 (in each case, excluding
    accrued but unpaid interest to the Redemption Date), computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points. “Treasury Rate” means, as of the time of computation, the yield to maturity as of
    such time of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 that has become publicly available at least two Business Days prior to the Redemption Date
    (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the Redemption Date to April 1, 2023; provided, however, that if the period from the Redemption
    Date to April 1, 2023, is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

   

  (6) Mandatory Redemption.

   

  The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Company may acquire the Notes by
    means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of the Indenture.

   

  
    A-5

    
      
 

  

   

  (7) Repurchase at the Option of Holder.

   

  (a)    If there is a Change of Control, the Company will
    be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price in cash equal to 101% of the
    aggregate principal amount thereof plus accrued and unpaid interest to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the date of
    purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will send a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

   

  (b)    If Company or a Restricted Subsidiary of the
    Company consummates any Asset Sales, within five days of each date on which the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company may be required to commence an offer to all Holders of Notes and all holders of other Indebtedness
    that is pari passu with the Notes containing provisions similar to those set forth in Section 4.10 of the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) to purchase the
    maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount plus accrued and unpaid interest to the date
    of purchase, in accordance with the procedures set forth in Section 3.09 of the Indenture. The Company may satisfy the foregoing obligations with respect to any Net Proceeds from an Asset Sale by making an Asset Sale Offer with respect to such Net
    Proceeds or equivalent amount prior to the time period that may be required by the Indenture with respect to all or a part of the available Net Proceeds (“Advance Portion”) in advance of being required to do so by the Indenture (an “Advance
      Offer”). If any Excess Proceeds (or in the case of an Advance Offer, Advance Portion) remain after consummation of an Asset Sale Offer, the Company (or any Restricted Subsidiary) may use such Excess Proceeds for any purpose not otherwise
    prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds (or in the case of an Advance Offer, the Advance Portion), the
    Trustee shall (subject to the Depositary’s applicable procedures) select the Notes and the representative of such other pari passu Indebtedness will (subject to the Depositary’s applicable procedures) select such other pari passu
    Indebtedness to be purchased on a pro rata basis.

   

  (c)    Holders of Notes that are the subject of a Change
    of Control Offer or an Asset Sale Offer will receive an offer to purchase from the Company prior to any related purchase date, and Holders of Definitive Notes may elect to have such Notes purchased by completing the form entitled “Option of Holder
      to Elect Purchase” attached to the Notes.

   

  (8) Notice of Redemption. Notice of redemption will be mailed (or sent
    electronically in the case of notices to DTC), at least 15 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be given more than 60 days
    prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 and
    in excess of $2,000, unless all of the Notes held by a Holder are to be redeemed. Notice of any redemption of the Notes (including upon an Equity Offering or in connection with a transaction (or series of related transactions) that constitute a Change
    of Control) may, at the Company’s discretion, be given prior to the completion thereof and be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering or Change of Control. In addition, if
    such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the Redemption Date may be delayed until such time (including more than 60 days after the date the notice of

    its obligations under such Guarantor’s Note Guarantee. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare the principal of, and accrued
    and unpaid interest, if any, on all the Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company or any Restricted
    Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, the principal of, and accrued and unpaid interest, if any, on all
    outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate
    principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default if it determines that withholding
    notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest, or premium, if any, on any Note. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the
    Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or
    premium, if any, on, or the principal of, the Notes. The Company and the Guarantors are required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company and the Guarantors are required, upon becoming
    aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default and what action the Company are taking or propose to take with respect thereto.

   

  (13) Trustee Dealings with the Company. The Trustee, in its individual or any
    other capacity, may make loans to, accept deposits from, and perform services for the Company or their Affiliates, and may otherwise deal with the Company or their Affiliates, as if it were not the Trustee.

   

  (14) No Recourse Against Others. A director, officer, partner, member, employee,
    incorporator, manager or unit holder or other owner of Equity Interest of the Company or any Guarantor, as such, will not have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture, the Note Guarantees or for
    any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes
    and the Note Guarantees.
