	3.
	Section 3.02 of the Agreement is hereby amended to add the following paragraph at the end of the section as follows:

“Notwithstanding the foregoing provisions of Section 3.02(b), unless Executive’s termination of employment occurs within two (2) years following a “change in control event” as defined in Treasury Regulation Section 1.409A-3(i)(5), then (i) the amount of severance pay under Section 3.02(b) that does not exceed the amount of severance that would have been payable under Section 4.02 or Section 4.04, as applicable, of the Employment Agreement, if such termination had not occurred during a Change in Control Period, shall be paid in the same time and form as provided under the Employment Agreement, and (ii) any additional amounts payable under Section 3.02(b) shall be paid at the time and manner set forth herein.  The requirements of this paragraph shall not apply to any severance that is exempt from Section 409A of the Code.”
		
	4.
	Section 4.01of the Agreement is hereby replaced in its entirety to read as follows:

“280G Payments. If any payment or benefit Executive will or may receive from the Company or otherwise (a “280G Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then any such 280G Payment (a “Payment”) shall be equal to the Reduced Amount (as defined below). The “Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment (after reduction) 

1

being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount (i.e., the amount determined by clause (x) or by clause (y)), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive’s receipt, on an after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in Payment is required pursuant to the preceding sentence the reduction shall be made (i) first by reducing severance pay under Section 3.02(b) of this Agreement (in inverse order of payment, if applicable), (ii) then by reducing other parachute payments, exclusive of equity awards, pro rata, and (iii) finally by reducing the accelerated vesting of equity awards, pro rata.”

		
	5.

“Relationship with the Company. Executive will separate from service with the Company effective _______________, 20____ (“Separation Date”).”

		
	6.

and none of the Holders of the Initial Notes and the Additional Notes shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

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

each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Notes Register or (ii) wire transfer to an account located in the United States maintained by
the payee, subject to the last sentence of this paragraph. Payments in respect of Notes represented by a Global Note (including principal and interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC. At
the Company’s option, payments in respect of Notes represented by Definitive Notes (including principal and interest) may be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if the Holder
elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may
accept in its discretion). 
 The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage, in
addition to those set forth on Exhibit A and in Section 2.1(d). The Company shall approve any notation, endorsement or legend on the Notes. Each Note shall be dated the date of its authentication, and the Trustee’s certificate of
authentication shall be substantially in the form set forth in Exhibit A. The terms of the Notes set forth in Exhibit A are part of the terms of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee,
by their execution and delivery of this Indenture, expressly agree to be bound by such terms.

INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE
HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES ON ITS OWN BEHALF AND ON BEHALF OF ANY INVESTOR ACCOUNT FOR WHICH IT HAS PURCHASED SECURITIES, TO OFFER, SELL, OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE “RESALE
RESTRICTION TERMINATION DATE”) THAT IS ONE YEAR (IN THE CASE OF RULE 144A SECURITIES) OR 40 DAYS (IN THE CASE OF REGULATION S SECURITIES) AFTER THE LATER OF THE ISSUE DATE HEREOF AND THE LAST DATE ON WHICH THE ISSUER OR ANY AFFILIATE OF THE
ISSUER WAS THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY), ONLY (A) TO THE ISSUER, (B) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A UNDER THE SECURITIES ACT, TO A PERSON IT REASONABLY

  
 39 

 
BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER
TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO OFFERS AND SALES THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER
AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE ISSUER’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE, OR TRANSFER PURSUANT TO CLAUSE (C), OR (D) TO REQUIRE THE DELIVERY OF AN
OPINION OF COUNSEL, CERTIFICATION, AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER OR THE ISSUER ON OR AFTER THE RESALE RESTRICTION TERMINATION DATE. 

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

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”),
NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF
DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 
 TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN
WHOLE, BUT NOT IN PART, TO DTC, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE
INDENTURE REFERRED TO ON THE REVERSE HEREOF. 
 (e) Book-Entry Provisions. 

(i) This Section 2.1(e) shall apply only to Global Notes deposited with the Trustee, as Notes Custodian. 

  
 40 

 (ii) Each Global Note initially shall (x) be registered in the name of
Cede & Co. as the nominee of DTC, (y) be delivered to the Trustee as Notes Custodian and (z) bear legends as set forth in Section 2.1(d). Transfers of a Global Note (but not a beneficial interest therein) will be limited to
transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except as set forth in Section 2.1(e)(v) and 2.1(f). If a beneficial interest in a Global Note is transferred or exchanged for a
beneficial interest in another Global Note, the Trustee will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like
increase in the principal amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another
Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other
procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest. 
 (iii)
Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by DTC or by the Trustee as the Notes Custodian or under such Global Note, and DTC
may be treated by the Company, the Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Company, the Guarantors, the Trustee or any agent of the Company, the Guarantors or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the
operation of customary practices of DTC governing the exercise of the rights of a Holder of a beneficial interest in any Global Note. 

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

(v) In connection with the transfer of an entire Global Note to beneficial owners pursuant to Section 2.1(f), such Global
Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and make available for delivery, to each beneficial owner identified by DTC in exchange for its beneficial
interest in such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. 
 (vi)
The registered Holder of a Global Note may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this
Indenture or the Notes. 

  
 41 

 (vii) Any Holder of a Global Note shall, by acceptance of such Global Note,
agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by (a) the Holder of such Global Note (or its agent) or (b) any holder of a beneficial interest in such Global
Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry. 
 (f) Definitive
Notes. 
 (i) Except as provided below, owners of beneficial interests in Global Notes will not be entitled to receive
Definitive Notes. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Definitive Notes in exchange for their beneficial interests in a Global Note upon written request in accordance with DTC’s and the
Registrar’s procedures. In addition, Definitive Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Note if (A) DTC notifies the Company that it is unwilling or unable to continue as
depositary for such Global Note or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by
the Company within 90 days of such notice, (B) subject to DTC’s rules, the Company, at its option, delivers to the Trustee and Registrar written notice stating that such Global Note shall be so exchangeable or (C) an Event of Default
has occurred and is continuing and DTC notifies the Company and the Trustee of DTC’s decision to exchange such Global Note for Definitive Notes. In the event of the occurrence of any of the events specified in the preceding sentence or in
clause (A), (B) or (C) of the preceding sentence, Definitive Notes delivered in exchange for any Global Note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of
DTC (in accordance with its customary procedures). 
 (ii) Any Definitive Note delivered in exchange for an interest in a
Global Note pursuant to Section 2.1(e)(iv) or (f) shall, except as otherwise provided by Section 2.6(d), bear the Restricted Notes Legend. 

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

  
 42 

 (iv) If a Definitive Note is transferred or exchanged for another Definitive
Note, (x) the Trustee will cancel the Definitive Note being transferred or exchanged, (y) the Company shall execute, and the Trustee shall authenticate and make available for delivery, one or more new Definitive Notes in authorized
denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Definitive Note (in the case of an exchange), registered in the
name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Definitive Note, the Company shall execute, and the Trustee shall authenticate and make
available for delivery to the Holder thereof, one or more Definitive Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Definitive Notes, registered in the name of
the Holder thereof. 
 SECTION 2.2 Execution and Authentication. One Officer shall sign the Notes for the Company by manual or
facsimile signature. If the Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless. 

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

At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for
delivery: (1) Initial Notes for original issue on the Issue Date in an aggregate principal amount of $300,000,000 and (2) subject to the terms of this Indenture, Additional Notes for original issue in an unlimited principal amount, in each
case upon a written order of the Company signed by one Officer of the Company (the “Company Order”). Such Company Order shall specify whether the Notes will be in the form of Definitive Notes or Global Notes, the amount of the Notes
to be authenticated and the date on which the original issue of Notes is to be authenticated and whether the Notes are to be Initial Notes or Additional Notes. 

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Notes.
Any such instrument shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Notes whenever the
Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for service of notices and
demands. 
 In case the Company, pursuant to Article IV, shall be consolidated or merged with or into any other Person or shall convey,
transfer, lease or otherwise dispose of all or substantially all of its assets in one or more transactions to any Person and the Successor Company shall have executed an indenture supplemental hereto with the Trustee pursuant to Article IV, any of
the Notes authenticated or delivered prior to such transaction may, from time to time, at the request of the 

  
 43 

 
Successor Company, be exchanged for other Notes executed in the name of the Successor Company, with such changes in phraseology and form as may be appropriate, but otherwise in substance of like
tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Company Order of the Successor Company, shall authenticate and make available for delivery Notes as specified in such order for the purpose of such
exchange. If Notes shall at any time be authenticated and delivered in any new name of a Successor Company pursuant to this Section 2.2 in exchange or substitution for or upon registration of transfer of any Notes, such Successor Company, at
the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time outstanding for Notes authenticated and delivered in such new name. 

SECTION 2.3 Registrar and Paying Agent. The Company shall maintain in the continental United States an office or agency where
Notes may be presented for registration of transfer or for exchange (the “Registrar”), and the Company shall maintain in New York, New York an office or agency where Notes may be presented for payment (the “Paying
Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Notes Register”). The Company or any of its Restricted Subsidiaries may act as Registrar or Paying Agent. The Company may
have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any co-registrar. 
 The Company shall enter into an appropriate agency agreement with any Registrar or Paying
Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of each such agent. If the Company fails to maintain a
Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7. 

The Company initially appoints the Trustee as Registrar and as Paying Agent for the Notes at its corporate trust office in New York, New York,
which, on the date hereof, is located at 140 Broadway, Suite 4624, New York, New York 10005. The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided,
however, that no such removal shall become effective until (i) acceptance of any appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or Paying Agent, as the case
may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may
resign at any time upon written notice to the Company and the Trustee. 
 SECTION 2.4 Paying Agent to Hold Money in Trust. By no
later than 11:00 a.m. (New York City time) on the date on which any principal or interest on any Note is due and payable, the Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal or
interest when due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Noteholders or the Trustee all money held by such Paying Agent for the payment
of principal or interest on the Notes (whether such assets have been distributed to it by the Company or other obligors on the Notes), shall notify the Trustee in writing of any default by the Company or any Guarantor in making any such payment and
shall during the continuance of any default by the 

  
 44 

 
Company (or any other obligor upon the Notes) in the making of any payment in respect of the Notes, upon the written request of the Trustee, forthwith deliver to the Trustee all sums held in
trust by such Paying Agent for payment in respect of the Notes together with a full accounting thereof. If the Company or a Restricted Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold
it as a separate trust fund. The Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds or assets disbursed by such Paying Agent. Upon complying with this
Section 2.4, the Paying Agent (if other than the Company or a Restricted Subsidiary of the Company) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect
to the Company, the Trustee shall serve as Paying Agent for the Notes. 
 SECTION 2.5 Noteholder Lists. The Trustee shall
preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Noteholders. If the Trustee is not the Registrar, the Company, on its own behalf and on behalf of each of the Guarantors,
shall furnish or cause the Registrar to furnish to the Trustee, in writing at least five 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 Noteholders. 
 SECTION 2.6 Transfer and Exchange. 

(a) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein)
for another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document
required by this Section 2.6. The Trustee shall promptly register any transfer or exchange that meets the requirements of this Section 2.6 by noting the same in the register maintained by the Trustee for the purpose, and no transfer or
exchange shall be effective until it is registered in such register. The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section 2.6 and Sections 2.1(e) and 2.1(f), as applicable,
and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and procedures of DTC, Euroclear and Clearstream. The Trustee shall refuse to register any requested transfer or exchange that does not comply with this
paragraph. 
 (b) Transfers of Rule 144A Notes. The following provisions shall apply with respect to any proposed registration of
transfer of a Rule 144A Note prior to the date which is one year after the later of the date of its original issue or the issuance of any Additional Notes and the last date on which the Company or any Affiliate of Company was the owner of such Notes
(or any predecessor thereto) (the “Resale Restriction Termination Date”): 
 (i) a registration of transfer
of a Rule 144A Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee in the form as set forth on the reverse of the Note that it is purchasing for its own account or an account with respect to which
it exercises sole investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on

  
 45 

 
Rule 144A and acknowledges that it has received such information regarding the Company as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and
that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; provided that no such written representation or other written certification shall be
required in connection with the transfer of a beneficial interest in the Rule 144A Global Note to a transferee in the form of a beneficial interest in that Rule 144A Global Note in accordance with this Indenture and the applicable procedures of DTC;
and 
 (ii) a registration of transfer of a Rule 144A Note or a beneficial interest therein to a Non-U.S. Person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Section 2.7 from the proposed transferee and, if requested by the Company, the
delivery of an Opinion of Counsel, certification and/or other information satisfactory to it. 
 (c) Transfers of Regulation S Notes.
The following provisions shall apply with respect to any proposed transfer of a Regulation S Note prior to the expiration of the Restricted Period: 

(i) a transfer of a Regulation S Note or a beneficial interest therein to a QIB shall be made upon the representation of the
transferee, in the form of assignment on the reverse of the certificate, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a
“qualified institutional buyer” within the meaning of Rule 144A, is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as the undersigned has
requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and

 (ii) a transfer of a Regulation S Note or a beneficial interest therein to a
Non-U.S. Person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Section 2.9 hereof from the proposed transferee and, if requested by the
Company, receipt by the Trustee or its agent of an Opinion of Counsel, certification and/or other information satisfactory to the Company. 

After the expiration of the Restricted Period, interests in the Regulation S Note may be transferred in accordance with applicable law without
requiring the certification set forth in Section 2.7 or any additional certification. 
 (d) Restricted Notes Legend. Upon the
transfer, exchange or replacement of Notes not bearing a Restricted Notes Legend, the Registrar shall deliver Notes that do not bear a Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing a Restricted Notes Legend
prior to the Resale Restriction Termination Date, the Registrar shall 

  
 46 

 
deliver only Notes that bear a Restricted Notes Legend unless (i) an Initial Note is being transferred pursuant to an effective registration statement or (ii) there is delivered to the
Registrar an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities
Act. Any Additional Notes sold in a registered offering shall not be required to bear the Restricted Notes Legend. 
 (e) Retention of
Written Communications. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.1 or this Section 2.6. The Company shall have the right to inspect and make copies of all
such letters, notices or other written communications at any reasonable time upon the giving of reasonable prior written notice to the Registrar. 

(f) Obligations with Respect to Transfers and Exchanges of Notes. 

(i) To permit registrations of transfers and exchanges, the Company shall, subject to the other terms and conditions of this
Article II, execute and the Trustee shall authenticate Definitive Notes and Global Notes at the Registrar’s request. 

(ii) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company may require the
Holder to pay a sum sufficient to cover any transfer tax assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charges payable upon exchange or transfer
pursuant to Section 2.2, 2.8, 2.10, 3.5, 3.9, 5.8 or 9.5). 
 (iii) The Company (and the Registrar) shall not be
required to register the transfer of or exchange of any Note (A) for a period (1) of 15 days before giving any notice of redemption of Notes or (2) beginning 15 days before an Interest Payment Date and ending on such Interest Payment
Date or (B) selected for redemption, except the unredeemed portion of any Note being redeemed in part. 
 (iv) Prior to
the due presentation for registration of transfer of any Note, the Company, any Guarantor, the Trustee, the Paying Agent or the Registrar may deem and treat the person in whose name a Note is registered as the owner of such Note for the purpose of
receiving payment of principal and interest on such Note and for all other purposes whatsoever, including the transfer or exchange of such Note, whether or not such Note is overdue, and none of the Company, any Guarantor, the Trustee, the Paying
Agent or the Registrar shall be affected by notice to the contrary. 
 (v) Any Definitive Note delivered in exchange for an
interest in a Global Note pursuant to Section 2.1(f) shall, except as otherwise provided by Section 2.6(d), bear the Restricted Notes Legend. 

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

  
 47 

 (g) No Obligation of the Trustee. The Trustee shall have no responsibility or
obligation to any beneficial owner of a Global Note, Agent Member or other Person with respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with
respect to the delivery to any participant, member, beneficial owner or other Person (other than DTC) of any notice (including any notice of redemption or purchase) or the payment of any amount or delivery of any Notes (or other security or
property) under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Notes shall be given or made only to or upon the order of the registered Holders (which
shall be DTC or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through DTC subject to the applicable rules and procedures of DTC. The Trustee may conclusively rely and shall be
fully protected in so relying upon information furnished by DTC with respect to its Agent Members and any beneficial owners. The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on
transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or beneficial owners in any Global Note) other than to require delivery of
such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof.

10.75% Senior Secured Notes due 2023 (the “Notes”) 

Ladies and Gentlemen: 
 In connection with our
proposed sale of $[________] aggregate principal amount of the Notes, we confirm that such sale has been effected pursuant to and in accordance with Regulation S under the United States Securities Act of 1933, as amended (the “Securities
Act”), and, accordingly, we represent that: 
 (a) the offer of the Notes was not made to a person in the United
States; 

  
 48 

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

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

registration requirements of the Securities Act. 
 In addition, if the sale is made during a restricted period and the provisions of Rule

 SECTION 2.8 Mutilated, Destroyed, Lost or Stolen Notes. If a mutilated Note is surrendered to the
Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the requirements of
Section 8-405 of the Uniform Commercial Code are met, such that the Noteholder (a) satisfies the Company or the Trustee that such Note has been lost, destroyed or wrongfully taken within a reasonable
time after such Noteholder has notice of such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to receiving such notification, (b) makes such request to the Company or Trustee prior to the Note being
acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the
Trustee; provided, however, if after the delivery of such replacement Note, a protected purchaser of the Note for which such replacement Note was issued presents for payment or registration such replaced Note, the Trustee or the
Company shall be entitled to recover such replacement Note from 

  
 49 

 
the Person to whom it was issued and delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to
the extent of any loss, damage, cost or expense incurred by the Company or the Trustee in connection therewith. Such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the
Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Note is replaced, and, in the absence of notice to the Company, any Guarantor or the Trustee that such Note has been acquired by a protected purchaser, the
Company shall execute, and upon receipt of a Company Order the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or wrongfully taken Note, a new Note of like
tenor and principal amount, bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or wrongfully
taken Note has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Note, pay such Note. 

Upon the issuance of any new Note under this Section 2.8, the Company may require that such Holder pay a sum sufficient to cover any
transfer tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of counsel and of the Trustee) in connection therewith. 

Subject to the proviso in the initial paragraph of this Section 2.8, every new Note issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or wrongfully taken Note shall constitute an original additional contractual obligation of the Company, any Guarantor and any other obligor upon the Notes, whether or not the mutilated, destroyed, lost or wrongfully taken
Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder. 

The provisions of this Section 2.8 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes. 
 SECTION 2.9 Outstanding Notes. Notes
outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those paid pursuant to Section 2.8 and those described in this Section as not outstanding. A Note does
not cease to be outstanding in the event the Company or an Affiliate of the Company holds the Note; provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the
provisions of Section 12.6 shall apply and (ii) in determining whether the Trustee shall be fully protected in making a determination whether the Holders of the requisite principal amount of outstanding Notes are present at a meeting of
Holders of Notes for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Notes
which a Trust Officer of the Trustee actually knows to be held by the Company or an Affiliate of the Company shall not be considered outstanding. 

If a Note is replaced pursuant to Section 2.8 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding
unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement pursuant to Section 2.8.

 If the Paying Agent segregates and holds in trust, in accordance with this Indenture, by
11:00 a.m. (New York City time) on a Redemption Date or other maturity date money sufficient to pay all principal and accrued interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or otherwise maturing, as the
case may be, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 

SECTION 2.10 Temporary Notes. In the event that Definitive Notes are to be issued under the terms of this Indenture, until such
Definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form, and shall carry all rights, of Definitive Notes but may have variations that the
Company consider appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for
Definitive Notes upon surrender of the temporary Notes at any office or agency maintained by the Company for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes,
the Company shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, one or more Definitive Notes representing an equal principal amount of Notes. Until so exchanged, the Holder of temporary Notes shall
in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Notes. 
 SECTION 2.11
Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation and dispose of such Notes in accordance with its internal policies and customary procedures (subject to the record retention
requirements of the Exchange Act) or deliver canceled Notes to the Company pursuant to written direction by one Officer of the Company. If the Company or any Guarantor acquires any of the Notes, such acquisition shall not operate as a redemption or
satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. The Company may not issue new Notes to replace Notes they have paid or delivered
to the Trustee for cancellation for any reason other than in connection with a transfer or exchange. 
 At such time as all beneficial
interests in a Global Note have either been exchanged for Definitive Notes, transferred, redeemed, repurchased or canceled, such Global Note shall be returned by DTC or the Notes Custodian to the Trustee for cancellation or retained and canceled by
the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Notes, transferred in exchange for an interest in another Global Note, redeemed, repurchased or canceled, the principal
amount of Notes represented by such Global Note shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note, by the Trustee or the
Notes Custodian, to reflect such reduction.

 SECTION 2.12 Payment of Interest; Defaulted Interest. Interest on any Note which
is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more predecessor Notes) is registered at the close of business on the regular record date for such
payment at the office or agency of the Company maintained for such purpose pursuant to Section 2.3. 
 Any interest on any Note which
is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the regular record date, and such defaulted interest and (to the extent
lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Company, at its election in each case, as
provided in clause (a) or (b) below: 
 (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose
names the Notes (or their respective predecessor Notes) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall
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 “Special Interest Payment Date”), and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Company shall fix a record date (the “Special Record Date”) for the payment of such Defaulted
Interest, which date shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly
notify the Trustee in writing of such Special Record Date, and in the name and at the expense of the Company, the Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment
Date therefor to be given in the manner provided for in Section 12.2, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment
Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following clause (b). 
 (b) The Company may make payment of any Defaulted
Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Company to the
Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 (c) The
Trustee shall not at any time be under any duty or responsibility to any Holder to determine the Defaulted Interest, or with respect to the nature, extent, or calculation of the amount of Defaulted Interest owed, or with respect to the method
employed in such calculation of the Defaulted Interest. 

  
 52 

 Subject to the foregoing provisions of this Section 2.12, each Note delivered under
this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. 

SECTION 2.13 Computation of Interest. Interest on the Notes shall be computed on the basis of a
360-day year of twelve 30-day months. 
 SECTION 2.14
CUSIP, Common Code and ISIN Numbers. The Company in issuing the Notes may use “CUSIP”, “Common Code” and “ISIN” numbers and, if so, the Trustee shall use “CUSIP”, “Common Code” and
“ISIN” numbers in notices of redemption or purchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the
Notes or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or purchase shall not be affected by any defect in or omission of
such CUSIP, Common Code and ISIN numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP, Common Code and ISIN numbers. 

ARTICLE III 
 COVENANTS 

SECTION 3.1 Payment of Notes. The Company shall promptly pay the principal and interest on the Notes on the dates and in the
manner provided in the Notes and in this Indenture. Principal and interest shall be considered paid on the date due if by 11:00 a.m. (New York City time) on such date the Trustee or the Paying Agent holds in accordance with this Indenture money
sufficient to pay all principal and interest then due. 
 The Company shall pay interest on overdue principal, and it shall pay interest on
overdue installments of interest (without regard to any grace period), at the rate specified in the Notes to the extent lawful. 

SECTION 3.2 Limitation on Indebtedness and Preferred Stock. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume,
Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur,” with “incurrence” having a correlative meaning) any Indebtedness (including Acquired
Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any Disqualified Stock or Preferred Stock; provided, however, that the Company or any Guarantor may incur
Indebtedness (including Acquired Debt), the Company may issue Disqualified Stock, and any Guarantor may issue Preferred Stock or Disqualified Stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal
quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or Preferred Stock is issued, as the case may be, would have been at least
2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if such additional Indebtedness had been incurred, or such Disqualified Stock or Preferred Stock had been issued, as the case may be,
at the beginning of such four-quarter period. 

  
 53 

 (b) Notwithstanding the foregoing, the first paragraph of this covenant will not prohibit
the incurrence of any of the following items of Indebtedness or the issuance of any Disqualified Stock or Preferred Stock described in clauses (4) and (7) (the items described below in this paragraph being referred to collectively as
“Permitted Debt”): 
 (1) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness and letters of credit under one or more Credit Facilities in an aggregate principal amount (or accreted value, as applicable) 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) with respect to borrowings under an ABL Facility, the Borrowing Base; 

(2) the incurrence by the Company and the Guarantors of Indebtedness represented by: 

(a) the Notes and the Subsidiary Guarantees issued on the Issue Date; 

(b) additional Priority Lien Debt (including additional Notes); provided that, immediately after giving effect to any
such incurrence, the aggregate principal amount of Priority Lien Debt incurred under this clause (2)(b) then outstanding (including all Priority Lien Debt incurred to refinance any Indebtedness incurred pursuant to this clause (2)(b)) does not
exceed the greater of (i) $37.5 million and (ii) an amount such that after giving effect to such incurrence and the use of proceeds thereof, the Priority Lien Leverage Ratio would not exceed 2.0 to 1.0; and 

(c) Junior Lien Debt; provided that, immediately after giving effect to any such incurrence, the aggregate principal
amount of Junior Lien Debt incurred under this clause (2)(c) then outstanding (including all Junior Lien Debt incurred to refinance any Indebtedness incurred pursuant to this clause (2)(c)) does not exceed the greater of (i) $100.0 million and
(ii) an amount such that after giving effect to such incurrence and the use of proceeds thereof, the Junior Lien Leverage Ratio would not exceed 1.0 to 1.0; 

(3) the incurrence by the Company or any of its Restricted Subsidiaries of Existing Indebtedness; 

(4) the incurrence or issuance by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in
exchange for, or the net proceeds of which are applied to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value, any Indebtedness (other than intercompany Indebtedness) or any Disqualified Stock of the Company,
or any Indebtedness (other than intercompany Indebtedness) or Preferred Stock of any of the Restricted Subsidiaries of the Company, in each case that was permitted by this Indenture to be incurred or issued pursuant to the first paragraph of this
covenant or under clauses (2), (3), (4), (6), (12) or (17) of this paragraph; 

  
 54 

 (5) 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 and a Restricted Subsidiary of the Company that is not a
Guarantor is the obligee on such Indebtedness, such Indebtedness will be subordinated to the payment in full of all Obligations then due with respect to the Notes, in the case of the Company, and the Subsidiary Guarantees, in the case of a
Guarantor, and (b)(i) 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 (ii) any sale or other transfer of
any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may
be, that is not then permitted by this clause (5); 
 (6) the incurrence by the Company or any of its Restricted Subsidiaries
of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred in connection with the purchase of, or for the purpose of financing the purchase of, all or any part of the purchase
price or cost of design, construction, installation, improvement, deployment, refurbishment or modification of property, plant or equipment or furniture, fixtures and equipment, in each case, used in the business of the Company or any of its
Restricted Subsidiaries, in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any
Indebtedness incurred pursuant to this clause (6), not to exceed the greater of (i) $100.0 million and (ii) $25.0 million plus 10.0% of the Company’s Consolidated Tangible Assets (in each case reduced by the then outstanding principal
amount of Capital Lease Obligations that were outstanding on the Issue Date and any refinancing, extensions or replacements thereof) determined as of the date of such incurrence; 

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries
of any Preferred Stock; provided, however, that (a) any subsequent issuance or transfer of Equity Interests that results in any such Preferred Stock being held by a Person other than the Company or a Restricted Subsidiary of the
Company, and (b) any sale or other transfer of any such Preferred Stock to a Person that is neither the Company nor its Restricted Subsidiary, will be deemed, in each case, to constitute an issuance of such Preferred Stock by such Restricted
Subsidiary that was not permitted by this clause (7); 
 (8) the incurrence by the Company or any of its Restricted
Subsidiaries of Indebtedness consisting of Hedging Obligations entered into in the ordinary course of business and not for speculative purposes; 

  
 55 

 (9) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred in connection with the disposition or acquisition of
any business, assets or a Restricted Subsidiary of the Company or any business or assets of its Restricted Subsidiaries, other than Guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or a
Restricted Subsidiary of the Company or any of its Restricted Subsidiaries for the purposes of financing such acquisition; provided, however, that (a) such Indebtedness is not reflected on the balance sheet of the Company or any
of its Restricted Subsidiaries (contingent obligations referred to in a footnote to financial statements and not otherwise reflected on the balance sheet will not be deemed to be reflected on such balance sheet for purposes of this clause (a)) and
(b) the maximum liability in respect of all such Indebtedness incurred in connection with a disposition shall at no time exceed the gross proceeds including noncash proceeds (the Fair Market Value of such noncash proceeds being measured at the
time received and without giving effect to any subsequent changes in value) actually received by the Company and its Restricted Subsidiaries in connection with such disposition; 

(10) the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a Restricted
Subsidiary of the Company that was permitted to be incurred by any other provision of this covenant; provided that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes, then the Guarantee must be subordinated
or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed; 
 (11) the issuance by a Restricted
Subsidiary of the Company of Disqualified Stock to the Company or to any of its Restricted Subsidiaries; provided, however, that any subsequent event or issuance or transfer of any Equity Interests that results in the owner of such
Disqualified Stock ceasing to be the Company or any of its Restricted Subsidiaries or any subsequent transfer of such Preferred Stock to a Person, other than the Company or one of its Restricted Subsidiaries, shall be deemed to be an issuance of
Disqualified Stock by such Subsidiary that was not permitted by this clause (11); 
 (12) the incurrence by the Company or
any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness; 
 (13) the incurrence by the Company or any of its
Restricted Subsidiaries of Indebtedness incurred in the ordinary course of business under (a) documentary letters of credit, or surety bonds or insurance contracts, which are to be repaid in full not more than one year after the date on which
such Indebtedness is originally incurred to finance the purchase of goods by the Company or a Restricted Subsidiary of the Company, (b) standby letters of credit, surety bonds or insurance contracts issued for the purpose of supporting
(i) workers’ compensation or similar liabilities of the Company or any of its Restricted Subsidiaries or (ii) performance, payment, deposit or surety obligations of the Company or any of its Restricted Subsidiaries and (c) bid,
advance payment and performance bonds and surety bonds or similar insurance contracts for the Company and its Restricted Subsidiaries, and refinancings thereof; 

  
 56 

 (14) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five business days; 

(15) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness to the extent that the net proceeds
thereof are promptly deposited to defease or to satisfy and discharge the Notes; 
 (16) the incurrence by the Company or any
of its Restricted Subsidiaries of Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its Restricted Subsidiaries; and 

(17) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness or the issuance by the
Company of any Disqualified Stock in an aggregate principal amount (or accreted value, as applicable), including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for
value any Indebtedness incurred or Disqualified Stock issued pursuant to this clause (17), not to exceed, at any one time outstanding, the greater of (a) $25.0 million and (b) 2.5% of Consolidated Tangible Assets as of any date of incurrence or
issuance after giving pro forma effect to such incurrence or issuance and the application of proceeds therefrom. 
 (c) To the extent the
Company’s Unrestricted Subsidiaries incur Non-Recourse Indebtedness and any such Indebtedness ceases to be Non-Recourse Indebtedness of such Unrestricted
Subsidiary, then such event shall be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that was subject to this covenant. 

(d) For purposes of determining compliance with this covenant, in the event that an item of proposed Indebtedness (including Acquired Debt),
Disqualified Stock or Preferred Stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (17) of the definition of “Permitted Debt” or is entitled to be incurred or issued pursuant
to Section 3.2(a), the Company will be permitted, in its sole discretion, to divide, classify, redivide and reclassify such item on the date of its incurrence or issuance, or later redivide or reclassify all or a portion of such item, in any
manner that complies with this Section 3.2. The accrual of interest or Preferred Stock or Disqualified Stock dividends or distributions, the accretion or amortization of original issue discount, the payment of interest in the form of additional
Indebtedness, the reclassification of Preferred Stock or Disqualified Stock as Indebtedness due to a change in accounting principles, and the payment of dividends or distributions on Preferred Stock or Disqualified Stock in the form of additional
shares or units of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this Indenture; provided, in each such
case, that the amount of any such accrual, accretion, amortization, reclassification or payment is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term. 

  
 57 

 (e) 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 Indebtedness, or first committed, in the case of revolving credit Indebtedness; 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 the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 3.2, the maximum amount of Indebtedness
that the Company or any Restricted Subsidiary of the Company may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted
Refinancing 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 Permitted Refinancing Indebtedness is
denominated that is in effect on the date of such refinancing. 
 SECTION 3.3 Limitation on Restricted Payments. 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: 

(1) declare or pay any dividend or make any other payment or distribution on account of the Company’s or any of its
Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the
Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such, in each case other than dividends or distributions declared or paid in Equity Interests (other than Disqualified Stock) of the Company or declared
or paid to the Company or any of its Restricted Subsidiaries; 
 (2) purchase, redeem or otherwise acquire or retire for
value (including without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company (other than any such Equity Interests owned by a Restricted Subsidiary of the Company); 

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, any
Subordinated Obligation, except a payment of interest or principal at or within one year of the Stated Maturity thereof; or 

  
 58 

 (4) make any Restricted Investment (all such payments and other actions set
forth in clauses (1) through (3) above and this clause (4) being collectively referred to as “Restricted Payments”), 

unless at the time of and after giving effect to such Restricted Payment: 

(a) no Payment Default or Event of Default shall have occurred and be continuing; and 

(b) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted
Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 3.2(a); and 

(c) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company or any of
its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2) through (11) of Section 3.3(b)), is equal to or less than the sum, without duplication, of: 

(i) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from October 1,
2018 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a loss, less 100% of such
loss), plus 
 (ii) 100% of (A) the aggregate net cash proceeds, or the Fair Market Value of assets or property other
than cash, received by the Company since the Issue Date from the issue or sale of (1) Equity Interests of the Company (other than Disqualified Stock), or (2) Disqualified Stock or debt securities of the Company that have been converted
into, or exchanged for, Equity Interests of the Company (other than Equity Interests (or Disqualified Stock or debt securities) of the Company sold to a Restricted Subsidiary of the Company and other than Disqualified Stock or debt securities that
have been converted into or exchanged for Disqualified Stock), (B) with respect to Indebtedness that is incurred on or after the Issue Date, the amount by which such Indebtedness of the Company or any of its Restricted Subsidiaries is reduced on the
Company’s consolidated balance sheet upon the conversion or exchange after the Issue Date of any such Indebtedness into or for Equity Interests of the Company (other than Disqualified Stock), and (C) the aggregate net cash proceeds, if
any, received by the Company or any of its Restricted Subsidiaries upon any conversion or exchange described in clause (A) or clause (B) above, plus 

  
 59 

 (iii) with respect to any Unrestricted Subsidiary that has been
redesignated as a Restricted Subsidiary after the Issue Date, the Fair Market Value of the aggregate Restricted Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary at the time of such redesignation, plus

 (iv) to the extent not already included in Consolidated Net Income for such period, an amount equal to the sum, without
duplication, of (A) if any Restricted Investment that was made by the Company or any Restricted Subsidiary after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the cash return of capital with respect to such
Restricted Investment resulting from such sale, liquidation or repayment (less any out-of-pocket costs incurred in connection with any such sale) plus (B) the net
reduction in such Restricted Investment resulting from (1) repayments of loans or advances, or other transfers of assets, in each case to the Company or any of its Restricted Subsidiaries, (2) other repurchases, repayments or redemptions
of such Restricted Investments, (3) the sale of any such Restricted Investment and (4) the release of any Guarantee (except to the extent any amounts are paid under such Guarantee) that constituted a Restricted Investment, plus 

(v) 100% of any dividends or distributions received by the Company or any of its Restricted Subsidiaries after the Issue Date
from an Unrestricted Subsidiary, to the extent such dividends or distributions were not otherwise included in Consolidated Net Income of the Company for such period. 

(b) Notwithstanding the foregoing, Section 3.3(a) shall not prohibit: 

(1) the payment of any dividend or distribution or the consummation of an irrevocable redemption within 60 days after the date
of the declaration of such dividend or distribution or the delivery of the irrevocable notice of redemption, as the case may be, if at the date of the declaration or the date on which such irrevocable notice is delivered, such dividend, distribution
or redemption would have complied with the provisions of this Indenture; 
 (2) the making of any Restricted Payment in
exchange for, or out of the net cash proceeds of, the substantially concurrent sale or issuance (other than to a Restricted Subsidiary of the Company) of Equity Interests of the Company (other than Disqualified Stock), with a sale or issuance being
deemed substantially concurrent if such Restricted Payment occurs not more than 120 days after such sale or issuance; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment shall be excluded
from clause (c)(ii) of Section 3.3(a); 
 (3) the making of any principal payment on, or the defeasance, redemption,
repurchase or other acquisition or retirement for value of any Subordinated Obligation (including the payment of any required premium and any fees and expenses incurred in connection with such defeasance, redemption, repurchase or other acquisition
or retirement for value) with the net cash proceeds from a substantially concurrent incurrence of, or in substantially concurrent exchange for the issuance of, Permitted Refinancing Indebtedness; 

  
 60 

 (4) the payment of any dividend or distribution by a Restricted Subsidiary
of the Company to the holders of its Equity Interests (other than Disqualified Stock), including holders of Equity Interests (other than Disqualified Stock) in a Permitted Water Subsidiary, on a pro rata basis or on a basis more favorable to the
Company or any of its Restricted Subsidiaries; 
 (5) so long as no Payment Default or Event of Default has occurred and is
continuing, (i) the acquisition in open-market purchases of our common stock of the Company for matching contributions to its employee stock purchase and deferred compensation plans in the ordinary course of business; and (ii) the
repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any current or former officer, employee, consultant or director (or any of their
respective heirs or estates or permitted transferees) of the Company or any of its Subsidiaries, provided, however, that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests pursuant to this
clause (5) will not exceed the sum of (x) $5.0 million in any twelve-month period (with unused amounts in any twelve-month period being carried over into the following twelve-month period but not subsequent periods), plus (y) the
aggregate amount of cash proceeds received by the Company from the issuance of Equity Interests (other than Disqualified Stock) to any such officer, employee, consultant or director that occurs after the Issue Date plus (z) the net cash
proceeds of key man life insurance policies received by the Company or its Restricted Subsidiaries after the Issue Date; 

(6) the repurchase of any Equity Interests of the Company or any of its Restricted Subsidiaries deemed to occur upon the

Interests of the Company or any of its Restricted Subsidiaries in connection with the exercise or vesting of any equity compensation (including, without limitation, stock or other equity options, warrants, restricted stock or equity, incentives,
phantom stock or equity or other rights to acquire Equity Interests of the Company or any of its Restricted Subsidiaries) in order to satisfy the Company’s or such Restricted Subsidiaries’ tax withholding obligations with respect to such

Subordinated Obligations plus accrued and unpaid interest thereon in the event of an Asset Sale, in connection with any change of control offer or asset sale offer required by the terms of such Subordinated Obligations, but only if: 

  
 61 

 (a) in the case of a Change of Control, the Company has first complied with
and fully satisfied its obligations under the Section 3.9, or 
 (b) in the case of an Asset Sale, the Company has
complied with and fully satisfied its obligations in accordance with Section 3.5;

Subsidiary that complies with Section 4.1; 
 (10) so long as no Payment Default or Event of Default has occurred and is
continuing, the declaration and payment of regularly scheduled or accrued dividends or distributions to holders of any class or series of Disqualified Stock of the Company or any Preferred Stock of any Restricted Subsidiary of the Company issued on

 (11) so long as no
Payment Default or Event of Default has occurred and is continuing, other Restricted Payments in an aggregate amount at any time outstanding not to exceed $15.0 million. 

(c) In determining whether any Restricted Payment is permitted by Section 3.3, the Company may allocate or reallocate all or any portion
of such Restricted Payment among clauses (1) through (11) of Section 3.3(b) or among such clauses and Section 3.3(a), provided that at the time of such allocation or reallocation, all such Restricted Payments, or allocated
portions thereof, would be permitted under the various provisions of this Section 3.3. The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment (or, in the case of a dividend or
distribution, on the date of declaration) of the Restricted Investment proposed to be made or the assets or securities proposed to be paid, transferred or issued by the Company or any Restricted Subsidiary of the Company, as the case may be,
pursuant to the Restricted Payment. The Fair Market Value of any cash Restricted Payment will be its face amount. 
 SECTION 3.4
Limitation on Restrictions on Distributions from Restricted Subsidiaries. 
 (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to: 

  
 62 

 (1) pay dividends or make any other distributions to the Company or any of
its Restricted Subsidiaries on its Capital Stock, or pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; provided that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior
to the payment of dividends or liquidating distributions on common stock shall not be deemed to be a restriction on the ability to make distributions on Capital Stock; 

(2) make loans or advances to the Company or any of its Restricted Subsidiaries; or 

(3) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries. 

(b) However, the restrictions in Section 3.4(a) will not apply to encumbrances or restrictions existing under or by reason of: 

(1) agreements governing Existing Indebtedness as in effect on the Issue Date and any amendments, restatements, modifications,
renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the encumbrances or restrictions contained in the amendments, restatements, modifications, renewals, supplements, refundings, replacements or
refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date; 

(2) this Indenture, the Notes (and any additional Notes), the Subsidiary Guarantees, the Collateral Agency Agreement and the
Security Documents; 
 (3) any future Liens that may be permitted to be granted under, or incurred not in violation of, any
other provisions of this Indenture; 
 (4) agreements governing other Indebtedness or Preferred Stock permitted to be
incurred or issued under the provisions of Section 3.2 and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the encumbrances or restrictions
contained therein are, in the good faith judgment of an officer of the Company not reasonably likely to have a material adverse effect on the ability of the Company to make required payments on the Notes; 

(5) applicable law or any applicable rule, regulation, order, approval, license, permit or similar restriction; 

(6) (a) any agreement or instrument relating to any property or assets acquired after the Issue Date, so long as such
encumbrance or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisition, and (b) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company
or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction

  
 63 

 
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, and any amendments, restatements,
modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings thereof; provided, that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions,
supplements, increases, refundings, replacements or refinancings are, in the good faith judgment of an officer of the Company, no more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided further, that,
in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; 
 (7) customary non-assignment provisions in contracts, agreements, licenses and leases entered into in the ordinary course of business; 

(8) purchase money obligations, security agreements or mortgage financings for property acquired in the ordinary course of

disposition of all or substantially all of the Capital Stock or assets of such Restricted Subsidiary pending the closing of such sale or disposition; 

(10) agreements relating to secured Indebtedness otherwise permitted to be incurred pursuant to Section 3.2 and not in
violation of Section 3.6, that limit the right of the debtor to dispose of assets securing such Indebtedness; 
 (11)
Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are, in the good faith judgment of an officer of the Company, not materially more restrictive,
taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; 
 (12) provisions with
respect to the disposition or distribution of assets in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business or with the
approval of the Company’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements; 

(13) encumbrances or restrictions contained in, or in respect of, Hedging Obligations incurred in the ordinary course of
business and permitted under this Indenture; 
 (14) encumbrances or restrictions on cash, Cash Equivalents or other deposits
or net worth imposed by customers or lessors under contracts or leases entered into in the ordinary course of business; 

  
 64 

 (15) any instrument governing Indebtedness or Capital Stock of a Foreign
Subsidiary; provided that such Indebtedness or Capital was otherwise permitted by the terms of this Indenture to be incurred or issued; and 

(16) restrictions on property received in connection with a sale or issuance of Equity Interests in a Permitted Water
Subsidiary that limit the use of such property in accordance with clause (12) of the definition of Asset Sale. 
 SECTION 3.5
Limitation on Sales of Assets and Subsidiary Stock.  
 (a) 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 at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed
of; and 
 (2) either (x) at least 75% of the consideration therefor received by the Company or such Restricted
Subsidiary is in the form of cash or Cash Equivalents or a combination thereof or (y) the Fair Market Value of the aggregate of all consideration other than cash or Cash Equivalents for all Asset Sales since the Issue Date would not exceed 5%
of Consolidated Tangible Assets of the Company after giving effect to such Asset Sales; provided that any of the following items shall be deemed to be cash and Cash Equivalents for the purposes of this clause (2): 

(a) other than with respect to an Asset Sale of Collateral, the assumption or forgiveness of any liabilities (as shown on the
Company’s or the Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary of the Company (other than liabilities that are by their terms subordinated to Notes issued under this Indenture or any
Subsidiary Guarantee) by the transferee of any such assets pursuant to a novation or other release or repurchase agreement that releases the Company or the Restricted Subsidiary from further liability; 

(b) any securities, Notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee
that are converted by the Company or the Restricted Subsidiary into cash or Cash Equivalents within 180 days following their receipt (to the extent of cash or Cash Equivalents received); and 

(c) other than with respect to an Asset Sale of Collateral, any stock or assets that constitute Replacement Assets; and 

(3) the Net Proceeds from any such Asset Sale of Collateral is paid directly by the purchaser thereof to the Collateral Agent
to be held in a Collateral Account for application in accordance with this covenant. 

  
 65 

 Notwithstanding the foregoing provisions of the above paragraph, the Company and its
Restricted Subsidiaries will not be required to cause any Net Proceeds to be held in a Collateral Account in accordance with clause (3) of the above paragraph except to the extent the aggregate Net Proceeds from all Asset Sales of Collateral
that would then be held in a Collateral Account exceed $15.0 million. 
 (b) Within 365 days after the receipt of any Net Proceeds from
an Asset Sale or, if the Company has entered into a binding commitment or commitments with respect to any of the actions described in clauses (1)(b) or (2)(a)-(d) below, within the later of (x) 360 days after the receipt of any Net Proceeds from an
Asset Sale or (y) 180 days after the entering into of such commitment or commitments, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds: 

(1) with respect to Asset Sales of Collateral, 

(a) to repay, redeem, repurchase or otherwise retire the Notes or any other Priority Lien Debt (or any combination thereof);
provided that if the Company or any Restricted Subsidiary shall so repay, redeem or reduce any Priority Lien Debt other than the Notes, the Company or such Restricted Subsidiary will redeem or equally and ratably repurchase (or offer to
repurchase) the Notes as provided either, at the Company’s option, under “—Optional Redemption,” through open-market purchases (to the extent such purchases are at a purchase price at or above 100% of the principal amount thereof
plus accrued but unpaid interest, if any) or by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer (as defined below)) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the
amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid to the date of such repurchases; or 

(b) to invest in Replacement Assets that would constitute Collateral; and 

(2) with respect to Asset Sales other than an Asset Sale of Collateral, 

(a) to acquire all or substantially all of the properties or assets of a Person primarily engaged in a Permitted Business if,
as a result of such acquisition, such Person becomes a Restricted Subsidiary of the Company; 
 (b) to acquire any Capital
Stock of a Person operating a Permitted Business if, after giving effect to such acquisition, such Person operating a Permitted Business is or becomes a Restricted Subsidiary of the Company; 

(c) to make capital expenditures in respect of the Company’s or its Restricted Subsidiaries’ Permitted Business or
make an Investment in Replacement Assets; 

  
 66 

 (d) to acquire other assets that are used or useful in a Permitted Business
or make an Investment in assets that will be used or useful in a Permitted Business; or 
 (e) to repay or retire
Indebtedness of the Company or any Restricted Subsidiary (other than subordinated Indebtedness or Indebtedness owed to an Affiliate of the Company). 

(c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 3.5(b) above shall be deemed to constitute
“Excess Proceeds.” Within 10 business days after the aggregate amount of Excess Proceeds exceeds $20.0 million, or earlier at the Company’s option, the Company will be required to make an offer to the Holders of Notes issued
thereunder and the holders of any other Priority Lien Debt that is subject to requirements with respect to the application of net proceeds from asset sales that are substantially similar to those contained in this Indenture (an “Asset Sale
Offer”) to purchase on a pro rata basis (with the Excess Proceeds prorated between the Holders of the Notes and such holders of such other Priority Lien Debt based upon outstanding aggregate principal amounts) the maximum principal amount
of the Notes and such other Priority Lien Debt that may be purchased or prepaid, as applicable, out of the prorated Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid
interest thereon to, but not including, the date of purchase, in accordance with the procedures set forth below. To the extent that the aggregate principal amount of the Notes and other Priority Lien Debt tendered (and electing to be redeemed or
repaid, as applicable) pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company and its Restricted Subsidiaries may use any remaining Excess Proceeds for general corporate purposes and any other purpose not prohibited by this
Indenture. If the aggregate principal amount of the Notes and such other Priority Lien Debt surrendered by holders thereof exceeds the amount of the prorated Excess Proceeds, the Company shall select the Notes and such other Priority Lien Debt to be
purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero. 
 The
Company will publicly announce the results of the Asset Sale Offer on or as soon as practicable after the date such Asset Sale Offer is completed. 

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 an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this
Section 3.5, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of the Company’s compliance with such securities laws or
regulations. 
 (d) Any Asset Sale Offer will remain open for a period of 20 Business Days following its commencement, except to the extent
that a longer period is required by applicable law (the “Asset Sale Offer Period”). No later than five Business Days after the termination of the Asset Sale Offer Period (the “Asset Sale Purchase Date”), the Company
will purchase the principal amount of Notes and such other Priority Lien Debt as may be required to be purchased pursuant to this Section 3.5 (the “Asset Sale Offer Amount”) or, if less than the Asset Sale Offer Amount has been
so validly tendered and not properly withdrawn, all Notes and such other Priority Lien Debt validly tendered and not properly withdrawn in response to the Asset Sale Offer. 

  
 67 

 If the Asset Sale Purchase Date is on or after an interest record date and on or before the
related Interest Payment Date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest will be payable to Holders who tender Notes
pursuant to the Asset Sale Offer. 
 On or before the Asset Sale Purchase Date, the Company will, to the extent lawful, accept for payment,
to the extent necessary on a pro rata basis as described above (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is
the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law), Notes and such other Priority Lien Debt or portions of Notes and such other Priority Lien Debt
so validly tendered and not properly withdrawn pursuant to the Asset Sale Offer, or if less than the Asset Sale Offer Amount has been validly tendered and not properly withdrawn, all Notes and such other Priority Lien Debt so validly tendered and
not properly withdrawn, in each case in minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000; provided that if, following the repurchase of a portion of a Note, the remaining principal amount of such Note
outstanding immediately after such repurchase would be less than $2,000, then the portion of such Note so repurchased shall be reduced such that the remaining principal amount of such Note outstanding immediately after such repurchase is $2,000. The
Company will deliver to the Trustee 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 3.5 and, in addition, the Company will deliver
all certificates and notes required, if any, by the agreements governing other Priority Lien Debt. The Company or the paying agent, as the case may be, will promptly (but in any case not later than five Business Days after the termination of the
Asset Sale Offer Period) mail (or otherwise deliver in accordance with the applicable procedures of DTC) to each tendering Holder of Notes or holder or lender of such other Priority Lien Debt, as the case may be, an amount equal to the purchase
price of the Notes or such other Priority Lien Debt so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the
Trustee, upon delivery of an authentication order from the Company, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such
new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. In addition, the Company will take any and all other actions required by the agreements governing such other Priority Lien Debt. Any Note
not so accepted will be promptly mailed or delivered by the Company to the Holder thereof. 
 SECTION 3.6 Limitation on
Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien (other than Permitted Liens) upon any of its property or assets (including
Capital Stock of a Restricted Subsidiary), whether owned on the Issue Date or acquired after that date, securing any Indebtedness. 

  
 68 

 SECTION 3.7 Designation of Restricted and Unrestricted Subsidiaries. 

The Board of Directors may designate any Subsidiary of the Company to be an Unrestricted Subsidiary under the circumstances and pursuant to
the requirements described in the definition of “Unrestricted Subsidiary” which requirements include that such designation will be made in compliance with this Section 3.7. For purposes of making the determination as to whether
such designation would be made in compliance with this Section 3.7, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be either
Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under Section 3.3(a) or constitute Permitted Investments to the extent available, as determined by the Company. All such
outstanding Investments will be deemed to constitute Investments in an amount equal to the Fair Market Value of such Investments at the time of such designation. Any designation of a Subsidiary of the Issuer as an Unrestricted Subsidiary will be
evidenced to the Trustee by filing with the Trustee an Officers’ Certificate certifying that such designation complied with the preceding conditions of this Section 3.7 and was permitted by the definition of “Unrestricted
Subsidiary” herein. 
 The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary;
provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if: 

(1) immediately after giving effect to such designation, the Company could incur at least $1.00 of additional Indebtedness
pursuant to the Fixed Charge Coverage Ratio test in Section 3.2(a) or the Fixed Charge Coverage Ratio of the Company immediately after giving effect to such designation would not be less than the Fixed Charge Coverage Ratio of the Company
immediately prior to such designation, and 
 (2) immediately before and immediately after giving effect to such designation,
no Default or Event of Default shall have occurred and be continuing. 
 SECTION 3.8 Limitation on Affiliate Transactions. 

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 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 any such
Person (each of the foregoing, an “Affiliate Transaction”) if such Affiliate Transaction involves aggregate consideration in excess of $2.0 million, unless: 

(1) such 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 transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is
otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view, evidenced (if required by clause (2) below) by the Officers’ Certificate provided for in clause (2) below; and 

  
 69 

 (2) the Company delivers to the Trustee: 

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of at least $20.0 million but equal to or less than $40.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above; and 

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in
excess of $40.0 million, a resolution of its Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of its Board of Directors, if any; 
 provided, that none of the following shall be deemed to be Affiliate
Transactions and therefore shall not be subject to the provisions of the preceding paragraph: 
 (1) any employment or
consulting agreement, equity award, equity option or equity appreciation agreement or plan, agreement, any officer or director indemnification, compensation or severance agreement or other similar compensation plan, agreement or arrangement entered
into by the Company or any of its Restricted Subsidiaries in the ordinary course of its business and any payments pursuant thereto; 

(2) transactions between or among (A) the Company and one or more Restricted Subsidiaries and (B) any Restricted
Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company
solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 

(4) the performance of any written agreement in effect on the Issue Date, as such agreement may be amended, modified or
supplemented from time to time; provided, however, that any amendment, modification or supplement entered into after the Issue Date will be permitted only to the extent that its terms do not adversely affect the rights of any Holders
of the Notes (as determined in good faith by an officer of the Company) as compared to the terms of the agreement in effect on the Issue Date; 

(5) loans or advances to officers, directors and employees for moving, entertainment and travel expenses, drawing accounts and
similar expenditures and other purposes, in each case, in the ordinary course of business; 
 (6) maintenance in the ordinary
course of business of customary benefit programs or arrangements for employees, officers or directors, including vacation plans, health and life insurance plans, deferred compensation plans and retirement or savings plans and similar plans; 

(7) fees and compensation paid to, and indemnity and insurance provided on behalf of, officers, directors, employees or
consultants of the Company or any of its Restricted Subsidiaries in their capacity as such, to the extent such fees and compensation are reasonable and customary; 

  
 70 

 (8) sales of Equity Interests of the Company (other than Disqualified Stock)
to, or receipt of capital contributions from, Affiliates of the Company or any of its Restricted Subsidiaries; 
 (9)
Restricted Payments that are permitted by Section 3.3 and any Permitted Investments; 
 (10) payments to an Affiliate in
respect of the Notes or any other Indebtedness of the Company or any of its Restricted Subsidiaries on the same basis as concurrent payments are made or offered to be made in respect thereof to non-Affiliates;

 (11) pledges by the Company or any of its Restricted Subsidiaries of Equity Interests in Unrestricted Subsidiaries for the
benefit of lenders or other creditors of Unrestricted Subsidiaries; 
 (12) any transactions between the Company or any
Restricted Subsidiary and any Person that is an Affiliate solely because a director of Person 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 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 clause (1) of the preceding paragraph. 

SECTION 3.9 Purchase of Notes Upon a Change of Control. 

(a) If a Change of Control occurs, each Holder of Notes will have the right, except as provided below, to require the Company 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 pursuant to an offer (a “Change of Control Offer”) on the terms set forth in this Indenture. In the Change of Control
Offer, the Company will offer a payment in cash (a “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of
purchase (the “Change of Control Payment Date”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control,
the Company will send a notice to each Holder of Notes, describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes properly tendered prior to the expiration date specified in the notice, which
date will be no earlier than 30 days and no later than 60 days from the date such notice is sent, pursuant to the procedures required by this Indenture and described in such notice. 

  
 71 

 (b) Promptly following the expiration of the Change of Control Offer, the Company will, to
the extent lawful, accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly following such acceptance, the Company will, on the Change of Control Payment Date: 

(1) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes
properly tendered; and 
 (2) deliver or cause to be delivered to the Trustee the Notes properly accepted for payment,
together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 

(c) The paying agent will promptly mail or wire transfer 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, make such payment through the facilities of the depositary), 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 of $2,000. Any Note so accepted for payment will
cease to accrue interest on and after the Change of Control Payment Date unless the Company defaults in making the Change of Control Payment. The Company will announce to the Holders of the Notes the results of the Change of Control Offer on or as
soon as practicable after the Change of Control Payment Date. 
 (d) The provisions described above that require the Company to make a
Change of Control Offer following a Change of Control will be applicable regardless of whether any other provisions of this Indenture are applicable, except as described in the immediately following paragraph. 

(e) 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 Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the
Change of Control Offer, (2) a notice of redemption with respect to all outstanding Notes has been given pursuant to Article V 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 has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has
purchased all Notes properly tendered in accordance with the terms of such Alternate Offer. 
 (f) Notwithstanding anything to the contrary
contained in this Indenture, a Change of Control Offer or an Alternate Offer may be made in advance of a Change of Control and conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of
Control at the time the Change of Control Offer or Alternate Offer is made. The closing date of any such Change of Control Offer made in advance of a Change of Control may be changed to conform to the actual closing date of the Change of Control;
provided that such closing date is not earlier than 30 days nor later than 60 days from the date the Change of Control Offer notice is sent as described in the first paragraph of this section. 

  
 72 

 (g) In the event that Holders of not less than 90% in aggregate principal amount of the
outstanding Notes accept a Change of Control Offer or Alternate Offer and the Company (or any third party making such Change of Control Offer in lieu of the Company as described above) purchases all of the Notes held by such Holders, the Company
will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such 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 the Change of Control Payment, plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain outstanding, to
the Redemption Date (subject to the rights 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). 

(h) 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 Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions
of this Indenture by virtue of such compliance. 
 SECTION 3.10 Reports. 

Regardless of whether required by the SEC’s rules and regulations, so long as any Notes are outstanding, the Company will furnish to the
Trustee and each Holder of Notes, within the time periods specified in the SEC’s rules and regulations: 
 (1) all
quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file such reports, and 

(2) all current reports that would be required to be filed with the SEC on Form 8-K if
the Company were required to file such reports. 
 For the avoidance of doubt, the above information will not be required to contain
(a) the separate financial information for Guarantors as contemplated by Rule 3-10 of Regulation S-X, (b) any financial statements of unconsolidated
subsidiaries or 50% or less owned persons as contemplated by Rule 3-09 of Regulation S-X, (c) any information contemplated by Rule
3-16 of Regulation S-X, (d) any schedules required by Regulation S-X, or (e) in each such case, any successor
provisions. 
 All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to
such reports. Each annual report on Form 10-K will include a report on the Company’s consolidated financial statements by the Company’s certified independent accountants. In addition, the Company
will file a copy of each of the reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the SEC will not accept such
a filing) and make such information available to securities analysts and prospective investors upon request.

 If at any time the Company is no longer subject to the periodic reporting requirements of
the Exchange Act for any reason, the Company will nevertheless continue filing the reports specified in the preceding paragraph with the SEC within the time periods specified above, unless the SEC will not accept such a filing. The Company agrees
that it will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the preceding, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred to
in the preceding paragraph on its website within the time periods that would apply if the Company were required to file those reports with the SEC. 

In addition, the Company and the Guarantors agree that, for so long as any Notes remain outstanding, at any time the Company is not required
to file the reports required by the preceding paragraphs with the SEC, they will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act. 
 Any and all Defaults or Events of Default arising from a failure to furnish in a timely manner any financial
information required by this covenant shall be deemed cured (and the Company shall be deemed to be in compliance with this covenant) upon furnishing such financial information as contemplated by this covenant (but without regard to the date on which
such financial statement or report is so furnished); provided that such cure shall not otherwise affect the rights of the Holders under Article VI 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. 

The Company will be deemed to have furnished such reports to the Trustee and the Holders of Notes if it has filed such reports with the SEC
using the EDGAR filing system and such reports are publicly available. 
 Delivery of such reports, information and documents to the Trustee
is for informational purposes only, and the Trustee’s receipt of the reports will not constitute constructive notice to either the Trustee or the Collateral Agent of any information contained therein or determinable from information contained
in them, including the Company’s compliance with any of its covenants under this Indenture and the Collateral Agency Agreement (as to which the Trustee and the Collateral Agent are entitled to rely exclusively on Officers’ Certificates).

 SECTION 3.11 Future Guarantors. 

The Company will cause (i) each Restricted Subsidiary (other than a Receivables Subsidiary) that is not a Guarantor that Guarantees or
otherwise becomes liable for any Indebtedness of the Company or another Guarantor, or (ii) each Restricted Subsidiary (other than a Foreign Subsidiary, a Receivables Subsidiary or an Immaterial Subsidiary) that owns any property or assets of a
type that would constitute Collateral (excluding Excluded Property), within 30 days of any such Guarantee or obligation, in the case of clause (i), or the acquisition or creation of such Restricted Subsidiary or such Restricted Subsidiary ceasing to
be an Immaterial Subsidiary, in the case of clause (ii), to execute and deliver to the Trustee a supplement to this Indenture substantially in the form of Exhibit B pursuant to which such Restricted Subsidiary will become a
Guarantor, subject to all of the provisions of Article X. Each Restricted Subsidiary that 

  
 74 

 
becomes a Guarantor after the date of issuance of the Notes will also become a party to the Collateral Agency Agreement and the applicable Security Documents and will take such actions as are
reasonably necessary or advisable to grant the Collateral Agent for the benefit of the Holders of the Notes and, the Trustee, a first-priority Lien in any Collateral held by such Restricted Subsidiary. 

SECTION 3.12 Maintenance of Office or Agency. The Company will maintain an office or agency where the Notes may be presented or
surrendered for payment, where, if applicable, the Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The corporate trust
office of the Trustee indicated in Section 2.3 shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company will give prompt written
notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the corporate trust office of the Trustee indicated in Section 12.2, and the Company hereby appoint the Trustee as its agent to receive all such presentations, surrenders, notices and
demands. 
 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 any such designation. The Company will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office
or agency. 
 SECTION 3.13 Corporate Existence. Except as otherwise provided in Article IV, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect its and its Restricted Subsidiaries’ existence, rights (charter and statutory), licenses and franchises; provided, however, that the Company shall not be
required to preserve any such Restricted Subsidiaries’ right, license or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken
as a whole. 
 SECTION 3.14 Payment of Taxes. The Company shall pay or discharge or cause to be paid or discharged, before the
same shall become delinquent, all material taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary; provided, however,
that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment or charge the amount, applicability or validity of which is being contested in good faith by appropriate proceedings. 

SECTION 3.15 Compliance Certificate. The Company and the Guarantors shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company ending after the Issue Date an Officers’ Certificate signed by the principal executive officer, the principal accounting officer or the principal financial officer of each of the Company and the Guarantors,
stating that a review of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to 

  
 75 

 
determining whether each of the Company and the Guarantors has performed its obligations under this Indenture, and further stating whether or not the signers know of any Default that occurred
during such period. If they do, the certificate shall describe such Default, its status and what action the Company is taking or proposes to take with respect thereto. 

SECTION 3.16 Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further
instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture. 

SECTION 3.17 Statement by Officers as to Default. The Company shall, so long as any Note is outstanding, deliver to the Trustee
within 30 days after the Company becomes aware of the occurrence of a Default or receives notice of such Default, as applicable, written notice of any Defaults, their status and what action the Company is taking or proposing to take in respect
thereof.

and 
 (3) except in the case of a consolidation or merger of the Company with or into a Restricted Subsidiary, or a sale,
assignment, transfer, conveyance or other disposition of properties or assets to the Company or a Restricted Subsidiary, either: 

(i) immediately after giving pro forma effect to such transaction as if such transaction had occurred at the beginning of the
applicable four-quarter period, the Company or the resultant, transferee or surviving Person (if other than the Company) would have a Fixed Charge Coverage Ratio that is not less than the Fixed Charge Coverage Ratio of the Company immediately prior
to such transaction; or 

  
 76 

 (ii) immediately after giving pro forma effect to such transaction as if
such transaction had occurred at the beginning of the applicable four-quarter period, the Company or the resultant transferee or surviving Person (if other than the Company) would be able to incur at least $1.00 of additional Indebtedness pursuant
to the Fixed Charge Coverage Ratio test set forth in Section 3.2(a); 
 (4) the Person formed by or surviving any such
consolidation or merger (if other than the Company) shall take such action (or agree to take such action) as may be necessary to cause any property or assets that constitute Collateral owned by or transferred to such Person to be subject to a
Priority Lien in the manner and to the extent required under the Security Documents; and 
 (5) the Company has delivered to
the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or disposition and such supplemental Indenture or other appropriate agreement (if any) comply with this Indenture and all conditions
precedent set forth therein relating to such transaction have been satisfied. 
 SECTION 4.2 Successor Substituted. Upon any
transaction or series of related transactions that are of the type described in, and are effected in accordance with, the foregoing paragraph, the surviving Person (if other than the Company) shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture and the Notes with the same effect as if such surviving Person had been named as the Company in this Indenture, and when a surviving Person duly assumes all of the obligations and
covenants of the Company pursuant to this Indenture and the Notes, the predecessor Person shall be relieved of all such obligations. 
 In
addition, the Company may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person. 

SECTION 4.3 Guarantor Merger. 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, another Person (regardless of whether such Guarantor is the resulting, transferee or surviving Person) other than the Company or another Guarantor, unless: 

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

(2) either: 

(a) the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving
any such consolidation or merger (if other than such Guarantor) unconditionally assumes, pursuant to a supplemental Indenture and other documentation, all the obligations of such Guarantor under this Indenture, its Subsidiary Guarantee and the
Security Documents to which it is party; or 
 (b) such sale or other disposition does not violate Section 3.5.

 ARTICLE V 

REDEMPTION OF NOTES 

SECTION 5.1 Redemption. The Notes may be redeemed at the Company’s option as provided in this Article V. The Notes will not
be subject to mandatory redemption sinking fund requirements. The Company may purchase Notes in the open market or privately negotiated transactions at any time or from time to time. 

SECTION 5.2 Optional Redemption. 

(a) Except as described below in this Section 5.2, the Notes are not redeemable at the Company’s option until October 15, 2020.

 (b) On or after October 15, 2020, the Company may on any one or more occasions redeem all or a part of the Notes, upon notice as
provided herein, 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 the applicable Redemption Date, if redeemed during the twelve-month period
beginning on October 15 of the years indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date: 

 

					
	 Year

	  	 	105.375	% 
	 2021
	  	 	102.688	% 
	 2022
	  	 	100.000	% 

 (c) At any time on or after April 15, 2019 and prior to October 15, 2020, concurrently with or
within 35 days after (but not prior to) the consummation of a transaction that constitutes a Company Sale, the Company or any acquirer may (together with any other concurrent redemption pursuant to another provision described herein) redeem all, but
not less than all, of the outstanding Notes, upon notice as provided herein, at a Redemption Price equal to (i) 105.375% of the principal amount of the Notes redeemed if the Company Sale is consummated on or after April 15, 2019 and on or prior
to October 15, 2019, or (ii) 108.063% of the principal amount of the Notes redeemed if the Company Sale is consummated after October 15, 2019 and prior to October 15, 2020), plus in each case accrued and unpaid interest, if any, to,
but not including, the Redemption Date (subject to the right of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date falling on or prior to the Redemption Date). 

(d) At any time or from time to time prior to October 15, 2020, the Company may also redeem all or a part of the Notes, upon notice as
provided herein, at a Redemption Price equal to the Make-Whole Price, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. The notice of redemption with respect to the
foregoing redemption need not set forth the Make-Whole Price but only the manner of calculation thereof. The Company will notify the Trustee of the Make-Whole Price with respect to any such redemption promptly after the calculation, and the Trustee
shall not be responsible for such calculation. 

  
 78 

 (e) At any time prior to October 15, 2020, the Company may, on any one or more
occasions, redeem up to 35% of the aggregate principal amount of Notes issued under this Indenture, upon notice as provided in this Indenture, with an amount of cash not greater than the net cash proceeds from one or more Equity Offerings at a
Redemption Price equal to 110.750% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, to the Redemption Date (subject to the rights of Holders of Notes on the relevant record date to receive interest due on the
relevant Interest Payment Date); provided that: 
 (1) at least 65% of the aggregate principal amount of Notes
originally 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. 

(f) The Notes are also subject to redemption as provided in Section 3.9(g). 

SECTION 5.3 Election to Redeem; Notice to Trustee. In case of any redemption at the election of the Company, the Company shall,
not later than five Business Days prior to giving notice of any redemption pursuant to Section 5.5 (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount
of Notes to be redeemed and, in the case of any redemption of less than all Notes, shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 5.4. Any such
notice may be cancelled at any time prior to notice of such redemption being given to any Holder and shall thereby be void and of no effect. 

SECTION 5.4 Selection by Trustee of Notes to Be Redeemed. If less than all the Notes are to be redeemed at any time pursuant to an
optional redemption, the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Notes not previously called for redemption, on a pro rata basis (or, in the
case of Notes issued in global form based on such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, such method that most nearly approximates pro rata selection as the Trustee deems fair
and appropriate, unless otherwise required by law). Any partial redemption may provide for the selection for redemption of portions of the principal of the Notes in denominations of $2,000 or larger integral multiples of $1,000; provided,
however, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less than $2,000. 

The Trustee shall promptly notify the Company of any Notes selected for redemption other than in accordance with DTC’s procedures and, in
the case of any Notes selected for partial redemption, the method it has chosen for the selection of Notes and the principal amount thereof to be redeemed. 

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

  
 79 

 SECTION 5.5 Notice of Redemption. Notice of redemption shall be given in the
manner provided for in Section 12.2, not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Notes to be redeemed, 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 Legal Defeasance or Covenant Defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article VIII. At the Company’s request, the Trustee shall give notice of redemption in the
Company’s name and at the Company’s expense; provided, however, that the Company shall deliver to the Trustee, at least five Business Days prior to the giving of such notice (unless a shorter period shall be satisfactory to
the Trustee), a Company Order requesting that the Trustee give such notice at the Company’s expense and setting forth the information to be stated in such notice as provided in the following items. 

All notices of redemption shall state: 

(1) the Redemption Date, 

(2) the Redemption Price, if then determinable, and otherwise the method for its determination and the amount of accrued
interest to the Redemption Date payable as provided in Section 5.7, if any, 
 (3) if less than all outstanding Notes
are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial
redemption, 
 (4) in case any Note is to be redeemed in part only, the notice which relates to such Note shall state the
portion of the principal amount thereof to be redeemed and that on and after the Redemption Date, upon surrender of such Note, the Holder will receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof
remaining unredeemed, 
 (5) that, subject to the satisfaction of any condition precedent specified in such notice, on the
Redemption Date the Redemption Price (and accrued interest, if any, to the Redemption Date payable as provided in Section 5.7) will become due and payable upon each such Note, or the portion thereof, to be redeemed, and, unless the Company
defaults in making the redemption payment, that interest, if any, on Notes called for redemption (or the portion thereof) will cease to accrue on and after said date, 

(6) the place or places where such Notes are to be surrendered for payment of the Redemption Price and accrued interest, if
any, 
 (7) the name and address of the Paying Agent, 

(8) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price, 

  
 80 

 (9) the CUSIP, Common Code and ISIN numbers, if applicable, and may state
that no representation is made as to the accuracy or correctness of the CUSIP, Common Code and ISIN numbers, if applicable, if any, listed in such notice or printed on the Notes, and 

(10) the Section of this Indenture, pursuant to which the Notes are to be redeemed. 

Any redemption or notice of redemption may, at the Company’s discretion, be subject to one or more conditions precedent specified in the
notice of redemption. 
 SECTION 5.6 Deposit of Redemption Price. Prior to 11:00 a.m., New York City time, on any Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company or any of the Company’s Restricted Subsidiaries is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.4) an
amount of money sufficient to pay the Redemption Price of and accrued interest on, all the Notes which are to be redeemed on that date, other than Notes or portions of Notes called for redemption that are beneficially owned by the Company and have
been delivered by the Company to the Trustee for cancellation. 
 SECTION 5.7 Notes Payable on Redemption Date. Notice of
redemption having been given as aforesaid, the Notes or portions of Notes so to be redeemed shall, subject to satisfaction of any conditions to such redemption as more fully described below, on the Redemption Date, become due and payable at the
Redemption Price therein specified (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Notes shall cease
to bear interest and the only right of the Holders thereof will be to receive payment of the Redemption Price and unpaid interest on such Notes to the Redemption Date. Any redemption or notice of redemption may, at the Company’s discretion, be
subject to one or more conditions precedent and, in the case of a redemption with the net cash proceeds of an Equity Offering, be given prior to and conditioned on the completion of the related Equity Offering. In the Company’s discretion, any
Redemption Date for any redemption that is subject to one or more conditions precedent may be delayed for up to 30 days until such time as any or all such conditions precedent are satisfied. Upon surrender of any such Note for redemption in
accordance with said notice, such Note shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date, provided, however, that installments of interest whose Stated Maturity is on
or prior to the Redemption Date will be payable to the Holder of such Note, or one or more predecessor Notes, registered as such as of the relevant record date. 

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the unpaid principal (including premium, if any)
shall, until paid, bear interest from the Redemption Date at the rate borne by the Notes. 
 SECTION 5.8 Notes Redeemed in Part.
Any Note which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at the office or agency of the Company maintained for such purpose pursuant to Section 3.12 (with, if the Company or the Trustee so
require, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly 

  
 81 

 
authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Note at the expense of the Company, a new Note or
Notes, of any authorized denomination as requested by such Holder, in an aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered; provided, that each such new Note will be in
a principal amount of $2,000 or larger integral multiple of $1,000. 
 ARTICLE VI 

DEFAULTS AND REMEDIES 

SECTION 6.1 Events of Default. An “Event of Default” wherever used herein, means any one of the following events
in relation to the Notes (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body): 
 (1) a default in payment when due of interest on the Notes for 30 days;

redemption, upon required purchase, upon declaration of acceleration or otherwise); 
 (3) the failure by the Company for 30
days to comply with any of its obligations under Article IV or any of its obligations in Sections 3.5 and 3.9 to offer to purchase or purchase Notes;

Indenture; 
 (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, which default: 
 (a) is caused by a failure to pay principal of or premium, if
any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (for purposes of this provision, a “payment default”); or 

(b) results in the acceleration of such Indebtedness prior to its express maturity; and 

  
 82 

 (c) in each case, the principal amount of any such Indebtedness, together

$40.0 million (excluding amounts covered by insurance), which judgments are not paid, discharged or stayed for a period of 60 days; 

(8) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company
or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary in an
involuntary case or proceeding under any applicable Bankruptcy Law or (B) a decree or order adjudging the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated
financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or
in respect of the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the last audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant
Subsidiary, under any applicable Bankruptcy Law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken
together (as of the last audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary, or of any substantial part of its or their property, or ordering the winding up or
liquidation of its or their affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; 

(9) the commencement by the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of
the last audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary of a voluntary case or proceeding under any applicable Bankruptcy Law or of any other case or proceeding to

petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken
together (as of the last audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary or of any substantial part of its or their property, or the making by it or them of an
assignment for the benefit of creditors, or the admission by it or them in writing of its or their inability to pay its or their debts generally as they become 

  
 83 

 
due, or the taking of corporate action by the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the last audited consolidated financial
statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary in furtherance of any such action; 

(10) except as permitted by this Indenture, any Subsidiary Guarantee shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any such Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee (other than by
reason of the termination of this Indenture or the release of any such Subsidiary Guarantee in accordance with this Indenture); and 

(11) the occurrence of any of the following: 

(a) except as permitted by this Indenture or the relevant Security Documents, any Security Document ceases for any reason to be
fully enforceable in any material respect; provided that it will not be an Event of Default under this clause (11)(a) if the sole result of the failure of one or more Security Documents to be fully enforceable in any material respect is that
any Lien purported to be granted under such Security Documents on Collateral, individually or in the aggregate, having a Fair Market Value of not more than $20.0 million ceases to be an enforceable and perfected first-priority Lien; 

(b) except as permitted by this Indenture or the relevant Security Documents, any Lien for the benefit of the Holders of the
Notes purported to be granted under any Security Document on Collateral, individually or in the aggregate, having a Fair Market Value in excess of $20.0 million ceases to be an enforceable and perfected first-priority Lien in any material
respect, subject only to Permitted Collateral Liens, and such condition continues for 30 days after written notice by the Collateral Agent of failure to comply with such requirement; provided that it will not be an Event of Default under this
clause if such condition results from the action or inaction of the Trustee or the Collateral Agent; or 
 (c) the Company or
any Restricted Subsidiary of the Company, or any Person acting on behalf of any of them, denies or disaffirms, in writing, any material obligation of the Company or such Restricted Subsidiary set forth in or arising under any Security Document for
the benefit of the Holders of the Notes. 
 However, a Default under clauses (4) and (5) of this Section 6.1 will not constitute
an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes notify the Company in writing and, in the case of a notice given by the Holders, the Trustee of the default and the Company does not
cure such Default within the time specified in clauses (4) and (5) of this Section 6.1 after receipt of such notice. In the case of an Event of Default specified in clause (6) of the first paragraph under this caption, such Event of
Default and all consequences thereof (excluding, however, any resulting payment default) will be annulled, waived and rescinded with respect to the Notes, automatically and without any action by the Trustee or the Holders of the Notes, if within 30
days after such Event of Default first arose the Company delivers 

  
 84 

 
an Officers’ Certificate to the Trustee stating that (1) the Indebtedness or Guarantee that is the basis for such Event of Default has been paid or discharged, (2) the holders of
the Indebtedness have rescinded or waived the acceleration giving rise to such Event of Default or (3) the Default that is the basis for such Event of Default has been otherwise cured; provided, however, that in no event shall an
acceleration of the principal amount of the Notes as described above be annulled, waived or rescinded upon the happening of any such events. 

SECTION 6.2 Acceleration. If an Event of Default (other than an Event of Default described in Section 6.1(8) and (9)) occurs
and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Notes by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the
principal of and accrued and unpaid interest, if any, on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default described in Section 6.1(8) and
(9) occurs and is continuing, the principal of and accrued and unpaid interest, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Without
limiting the generality of the foregoing, it is understood and agreed that if the Notes are accelerated or otherwise become due prior to their Maturity Date, in each case, in respect of any Event of Default (including, but not limited to, Sections
6.1(8) or (9) (including the acceleration of claims by operation of law)), the then applicable premium applicable with respect to an optional redemption of the Notes (which, for all purposes of the paragraphs under “Events of Default,”
shall be understood to include the applicable Redemption Price, including the Make-Whole Price, if then applicable) will also be due and payable as though the Notes were optionally redeemed and shall constitute part of the Obligations, in view of
the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of each Holder’s lost profits as a result thereof. Any premium payable above shall be presumed to
be the liquidated damages sustained by each Holder as the result of the early redemption and the Company agrees that it is reasonable under the circumstances currently existing. The premium shall also be payable in the event the Notes (and/or the
Indenture) are satisfied or released by foreclosure (whether by power of judicial proceeding), deed in lieu of foreclosure or by any other means. THE COMPANY EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY
PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Company expressly agrees (to the fullest extent it may lawfully do so) that: (A) the premium
is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the premium shall be payable notwithstanding the then prevailing market rates at the time payment is
made; (C) there has been a course of conduct between Holders and the Company giving specific consideration in this transaction for such agreement to pay the premium; and (D) the Company shall be estopped hereafter from claiming differently
than as agreed to in this paragraph. The Company expressly acknowledge that its agreement to pay the premium to Holders as herein described is a material inducement to Holders to purchase the Notes. 

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

  
 85 

 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 Noteholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. 
 SECTION 6.4 Waiver of Past
Defaults. The Holders of a majority in principal amount of the outstanding Notes by written notice to the Trustee (with a copy to the Company, but the applicable waiver or rescission shall be effective when the notice is given to the Trustee)
may (a) waive, by their consent (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), an existing Default or Event of Default and its consequences except (i) a Default or Event of
Default in the payment of the principal of or interest on a Note or (ii) a Default or Event of Default in respect of a provision that under Section 9.2 cannot be amended without the consent of each Noteholder affected and (b) rescind
any acceleration with respect to the Notes and its consequences if (1) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of
the principal of and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any consequent right. 
 SECTION 6.5 Control by Majority. The Holders
of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or the Collateral Agent or of exercising any trust or power conferred on the
Trustee or the Collateral Agent, as the case may be. However, the Trustee or the Collateral Agent, as the case may be, may refuse to follow any direction that conflicts with law or this Indenture, the Notes or the Subsidiary Guarantees or, subject
to Sections 7.1 and 7.2, that the Trustee or the Collateral Agent determines is unduly prejudicial to the rights of other Noteholders or would involve the Trustee or the Collateral Agent in personal liability; provided, however, that
the Trustee or the Collateral Agent may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any such action hereunder, the Trustee or the Collateral Agent shall be entitled to
indemnification or security satisfactory to it against all losses and expenses caused by taking or not taking such action. 

SECTION 6.6 Limitation on Suits. Subject to Section 6.7, a Noteholder may not pursue any remedy with respect to the Notes
Documents unless: 
 (1) such Holder has previously given the Trustee written notice that an Event of Default is continuing;

 (2) Holders of at least 25% in principal amount of the outstanding Notes have requested in writing the Trustee to pursue
the remedy; 

  
 86 

 (3) such Holders have offered the Trustee security or indemnity satisfactory
to it against any loss, liability or expense; 
 (4) the Trustee has not complied with such request within 60 days after the
receipt thereof and the offer of security or indemnity; and 
 (5) the Holders of a majority in principal amount of the
outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period. 

A Noteholder may not use this Indenture to prejudice the rights of another Noteholder or to obtain a preference or priority over another
Noteholder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Noteholders). 

SECTION 6.7 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture (including
Section 6.6), the contractual right of any Holder to receive payment of principal of or interest or premium, if any, on the Notes held by such Holder, on or after the respective due dates expressed or provided for in the Notes, or to bring suit
for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

SECTION 6.8 Collection Suit by Trustee. If an Event of Default specified in clause (1) or (2) of Section 6.1 occurs and
is continuing, the Trustee may recover judgment in its own name and as Trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts
provided for in Section 7.7. 
 SECTION 6.9 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the
Noteholders allowed in any judicial proceedings relative to the Company or its Subsidiaries or its or their respective creditors or properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a
member of any official committee of creditors appointed in such matter and may vote on behalf of the Holders in any election of a Trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding
is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7. 

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

  
 87 

 SECTION 6.10 Priorities. 

(a) Subject to the Collateral Agency Agreement, if the Trustee or the Collateral Agent collects any money or property pursuant to this Article
VI, it shall pay out (or in the case of the Collateral Agent, it shall pay to the Trustee to pay out) the money in the following order: 

FIRST: to the Trustee, the Collateral Agent and their agents and attorneys for amounts due to them under this Indenture,
including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the Collateral Agent and the costs and expenses of collection; 

SECOND: to Holders of Notes for amounts due and unpaid on the Notes for principal and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for principal 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 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 and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by the Company, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in outstanding principal amount of the Notes. 

ARTICLE VII 
 TRUSTEE AND
COLLATERAL AGENT 
 SECTION 7.1 Duties of Trustee and Collateral Agent. 

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

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

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

  
 88 

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

(c) The Trustee may not be relieved from liability for its own 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; 

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that
the Trustee was negligent in ascertaining the pertinent facts; 
 (3) the Trustee shall be liable with respect to any action
it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5; and 

(4) no provision of this Indenture, the Collateral Agency Agreement and Notes Documents, the Intercreditor Agreement, the Notes
or the Subsidiary Guarantees shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or thereunder or in the exercise of any of its rights or powers, if it
shall have reasonable grounds to believe that repayment of such funds or adequate indemnity or security against such risk or liability is not reasonably assured to it. 

(d) Every provision of this Indenture, the Collateral Agency Agreement, the Notes Documents and the Intercreditor Agreement that in any way
relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. 
 (e) The Trustee shall not be liable for interest
on any money received by it except as the Trustee may agree in writing with the Company. 
 (f) Money held in trust by the Trustee need not
be segregated from other funds except to the extent required by law. 
 (g) Every provision of this Indenture, the Collateral Agency
Agreement, the Notes Documents and the Intercreditor Agreement relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.1. 

  
 89 

 (h) Unless otherwise specifically provided in this Indenture, the Collateral Agency
Agreement, the Notes Documents and the Intercreditor Agreement, any demand, request, direction or notice from the Company shall be sufficient if signed by two Officers of the Company. 

SECTION 7.2 Rights of Trustee . Subject to Section 7.1: 

(a) The Trustee may conclusively rely on any document (whether in its original, facsimile or other electronic form) believed by it in good
faith 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, but such entity, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if such entity shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole
cost of the Company, and such entity shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The
Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officers’ Certificate or Opinion of Counsel. 

(c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed
with due care. Neither the Trustee nor the Collateral Agent shall be responsible for the misconduct or negligence of the collateral agent appointed by the Company pursuant to an agreement dated the date hereof among Corporation Service Company, as
collateral agent, UMB Bank, N.A, as secured party, and the Company, as debtor. 
 (d) The Trustee shall not be liable for any action it
takes or omits to take in good faith which it believes to be authorized or within its rights or powers. 
 (e) The Trustee may consult with
counsel of its selection, and the advice or Opinion of Counsel with respect to legal matters relating to this Indenture, the Collateral Agency Agreement, the Notes Documents and the Intercreditor Agreement, the Notes or the Subsidiary Guarantees
shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder or under the Collateral Agency Agreement, the Notes Documents and the Intercreditor Agreement, the Notes or
the Subsidiary Guarantees in good faith and in accordance with the advice or opinion of such counsel. 
 (f) The Trustee shall not be deemed
to have notice of any Default or Event of Default unless a Trust Officer has actual knowledge thereof or unless written notice of any event which is in fact such a Default or Event of Default is received by the Trustee at the corporate trust office
specified in Section 12.2, and such notice references the Notes and this Indenture. 
 (g) The rights, privileges, protections,
immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in its capacity hereunder, and to each agent, custodian and other Person employed to act hereunder. 

  
 90 

 (h) The Trustee shall not be under any obligation to exercise any of the rights or powers
vested in it by this Indenture, the Collateral Agency Agreement, the Notes Documents, the Intercreditor Agreement, the Notes or the Subsidiary Guarantees at the request, order or direction of any of the Holders pursuant to the provisions of this
Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby. 

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

 (j) Whenever in the administration of this Indenture, the Collateral Agency Agreement, the Notes Documents, the Intercreditor Agreement,
the Notes or the Subsidiary Guarantees the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder or thereunder, the Trustee (unless other evidence be herein specifically
prescribed) may request and may in good faith conclusively rely upon an Officers’ Certificate. 
 (k) In no event shall the Trustee be
responsible or liable for any special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit), irrespective of whether such entity has been advised of the likelihood of such loss or
damage and regardless of the form of action. 
 (l) The parties hereto acknowledge, in accordance with Section 326 of the Patriot Act,
that the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a
relationship or opens an account with the Trustee. The Company and the Guarantors agree that they will provide the Trustee with all such information as it may reasonably request in order to satisfy the requirements or its obligations under the
Patriot Act. 
 (m) Any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution. 
 (n) The Trustee shall not be required to give
any bond or surety in respect of the performance of its powers and duties hereunder. 
 (o) The Trustee may request that the Company and
Subsidiary Guarantors deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture. 

(p) The Trustee shall not have a duty to inquire as to the performance of the Company with respect to (i) the covenants, agreements or
other terms and conditions set forth herein or in any Notes Document, (ii) the occurrence of any Default or Event of Default, (iii) the creation, perfection or priority of any Lien purported to be created by the Notes Documents,
(iv) the value or the sufficiency of any Collateral or (v) the satisfaction of any condition set forth herein or in any Notes Documents, other than to confirm receipt of items expressly required to be delivered to the Trustee. 

  
 91 

 SECTION 7.3 Individual Rights of Trustee. The Trustee in its individual or any
other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, the Guarantors or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like
rights. However, the Trustee must comply with Sections 7.10 and 7.11. In addition, the Trustee shall be permitted to engage in transactions with the Company; provided, however, that if the Trustee acquires any conflicting interest, the
Trustee must eliminate such conflict within 90 days of acquiring such conflicting interest or resign. 
 SECTION 7.4
Trustee’s and Collateral Agent’s Disclaimer. Neither the Trustee nor the Collateral Agent shall be responsible for or makes any representation as to the validity or adequacy of this Indenture, the
Subsidiary Guarantees or the Notes, shall be accountable for the Company’s use of the proceeds from the sale of the Notes, shall be responsible for the use or application of any money received by any Paying Agent other than the Trustee or any
money paid to the Company pursuant to the terms of this Indenture or shall be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the
Trustee’s certificate of authentication. 
 SECTION 7.5 Notice of Defaults. If a Default or Event of Default occurs and is
continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall send to each Noteholder 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 or interest on any Note (including payments pursuant to the optional redemption or required repurchase provisions of such Note), the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding
the notice is in the interests of Noteholders. 
 SECTION 7.6 [Reserved]. 

SECTION 7.7 Compensation and Indemnity. The Company and the Guarantors shall, jointly and severally, pay to each of the Trustee
and Collateral Agent from time to time reasonable compensation for its services hereunder and under the Notes and the Subsidiary Guarantees. Such compensation shall not be limited by any law on compensation of a Trustee of an express trust. The
Company and the Guarantors shall reimburse the Trustee and the Collateral Agent upon request for all reasonable out-of-pocket expenses incurred or made by it, including,
but not limited to, costs of collection, costs of preparing reports, certificates and other documents, costs of preparation and sending of notices to Noteholders. Such expenses shall include the reasonable compensation and expenses, disbursements
and advances of the Trustee’s and the Collateral Agent’s agents, counsel, accountants and experts. The Company and the Guarantors shall, jointly and severally, indemnify the Trustee and the Collateral Agent against any and all loss,
liability, damages, claims or expense (including reasonable attorneys’ fees and expenses) incurred by the Trustee without willful misconduct or negligence on its part or incurred by the Collateral Agent without willful misconduct or gross
negligence, as the case may be, as found by non-appealable order of a court of competent jurisdiction, in connection with the acceptance and administration of this trust and the performance of their respective
duties hereunder and under the Notes and the Subsidiary Guarantees, including the costs and expenses of enforcing this Indenture (including this Section 7.7), the Notes and the Subsidiary Guarantees and of defending itself against any claims
(whether asserted by any Noteholder, the Company, any Guarantor or otherwise). The Trustee and the Collateral Agent shall notify the Company promptly of any claim for which it may seek 

  
 92 

 
indemnity of which it has received written notice. Failure by the Trustee or the Collateral Agent to so notify the Company shall not relieve the Company of its obligations hereunder except to the
extent the Company is prejudiced thereby. The Company and the Guarantors shall defend the claim and the Trustee and the Collateral Agent shall provide reasonable cooperation at the Company’s expense in the defense. The Trustee and the
Collateral Agent may have separate counsel and the Company shall pay the fees and expenses of such counsel; provided that the Company shall not be required to pay the fees and expenses of such separate counsel if it engages counsel
satisfactory to the Trustee and the Collateral Agent and assumes the Trustee’s or the Collateral Agent’s defense, and, in the reasonable judgment of outside counsel to the Trustee and the Collateral Agent, there is no conflict of interest
between the Company and the Trustee and the Collateral Agent in connection with such defense. 
 To secure the Company’s payment
Obligations in this Section 7.7, the Trustee and the Collateral Agent shall have a lien prior to the Notes on all money or property held or collected by the Trustee and the Collateral Agent other than money or property held in trust to pay
principal of and interest on particular Notes. Such lien shall survive the satisfaction and discharge of this Indenture. The Trustee’s and the Collateral Agent’s right to receive payment of any amounts due under this Section 7.7 shall
not be subordinate to any other liability or Indebtedness of the Company. 
 The Company’s and Guarantors’ payment obligations
pursuant to this Section shall survive the discharge of this Indenture and the resignation or removal of the Trustee and/or the Collateral Agent. Without prejudice to any other rights available to the Trustee and the Collateral Agent under
applicable law, when the Trustee incurs expenses after the occurrence of a Default specified in clause (8) or clause (9) of Section 6.1, the expenses are intended to constitute expenses of administration under any Bankruptcy Law. 

SECTION 7.8 Replacement of Trustee . The Trustee may resign at any time by so notifying the Company in writing. The Holders
of a majority in principal amount of the Notes may remove the Trustee by so notifying the removed Trustee in writing and may appoint a successor Trustee with the Company’s written consent, which consent will not be unreasonably withheld. The
Company shall remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 hereof; 

(2) the Trustee is adjudged bankrupt or insolvent; 

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

(4) the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns or is removed by the Company or by the Holders of a majority in principal amount of the Notes and such Holders do not
reasonably promptly appoint a successor as described in the preceding paragraph, or if a vacancy exists in the office of the Trustee for any other reason, the Company shall promptly appoint a successor entity. 

  
 93 

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

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of at least 10% in principal amount of the Notes may petition, at the Company’s expense, any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee fails to comply with Section 7.10, any Noteholder, who has been a bona fide Holder of a Note for at least six months, may
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 Notwithstanding
the replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee. 

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

 In case at the time such successor or successors by merger, conversion or consolidation to the Trustee or the Collateral Agent shall
succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee or the Collateral Agent may adopt the certificate of authentication of any predecessor trustee, and
deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall only apply to its successor or successors by merger,
consolidation or conversion. 
 SECTION 7.10 Eligibility; Disqualification. This Indenture shall always have a Trustee that
satisfies the requirements of the TIA § 310(a)(1), (2) and (5) in every respect. The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. 

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

SECTION 7.12 Application for Instruction from the Company. Any application by the Trustee or the Collateral Agent for written
instructions from the Company may, at the option of the Trustee or the Collateral Agent, set forth in writing any action proposed to be taken or omitted by the Trustee or the Collateral Agent under this Indenture and the date on or after which such

  
 94 

 
action shall be taken or such omission shall be effective. The Trustee or the Collateral Agent shall not be liable for any action taken by, or omission of, the Trustee or the Collateral Agent in
accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any Officer of the Company actually receives such application, unless
any such Officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee or the Collateral Agent shall have received written instructions in response
to such application specifying the action to be taken or omitted. 
 SECTION 7.13 Duties and Rights of the Collateral Agent. The
duties, rights, privileges, protections and immunities of the Collateral Agent are provided in the Collateral Agency Agreement, which duties, rights, privileges, protections and immunities are incorporated herein by reference. 

ARTICLE VIII 
 DISCHARGE OF
INDENTURE; DEFEASANCE 
 SECTION 8.1 Discharge of Liability on Notes; Defeasance. 

(a) Subject to Section 8.1(c), when 

(i) (x) all Notes that have been authenticated (other than Notes replaced or paid pursuant to Section 2.8 and Notes for
whose payment money has been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust), have been delivered to the Trustee for cancellation or (y) all outstanding Notes
not theretofore delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the giving 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, Government Securities, or a combination thereof, in such amounts as will be sufficient (in the case of a
deposit in U.S. Obligations or a combination of cash and U.S. Obligations in the opinion of an accounting, appraisal or investment banking firm of national standing), without consideration of any reinvestment of interest, to pay and discharge the
entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal and interest on, the Notes to the date of Stated Maturity or redemption; 

(ii) in respect of clause (i)(y), no Default has occurred and is continuing on the date of the deposit (other than an Event of
Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to
which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than the Indenture); 

  
 95 

 (iii) the Company has paid or caused to be paid all sums payable by it under
this Indenture; and 
 (iv) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply
the deposited money toward the payment of such Notes at Stated Maturity or on the Redemption Date, as the case may be, 
 then the Trustee shall acknowledge
satisfaction and discharge of this Indenture (and the Company’s and the Guarantors’ obligations under the other Notes Documents will terminate) on demand of the Company (accompanied by an Officers’ Certificate and an Opinion of
Counsel stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with) and at the cost and expense of the Company. If Government Securities shall have been deposited in
connection with such satisfaction and discharge, then as a further condition to such satisfaction and discharge, the Trustee shall have received a certificate from an accounting, appraisal or investment banking firm of national standing to the
effect set forth in Section 8.2(1). The Collateral will be released from the Liens securing the Notes, as provided in the Collateral Agency Agreement, upon a satisfaction and discharge in accordance with the provisions described in this
Section 8.1. 
 (b) Subject to Sections 8.1(c) and 8.2, the Company at any time may terminate (i) all of its obligations under the
Notes and this Indenture (“Legal Defeasance”), and after giving effect to such Legal Defeasance, any omission to comply with such obligations shall no longer constitute a Default or Event of Default or (ii) its obligations
under Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.8, 3.9, 3.10, 3.11, 3.14 and 3.15 and clause (3) of the first paragraph of Section 4.1), and the Company may omit to comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and
such omission to comply with such covenants shall no longer constitute a Default or an Event of Default under Section 6.1(3), Section 6.1(4), Section 6.1(5) (to the extent applicable to any defeased covenants), Section 6.1(6),
Section 6.1(7), Section 6.1(8) (with respect to Significant Subsidiaries), Section 6.1(9) (with respect to Significant Subsidiaries), and the events specified in such Sections shall no longer constitute an Event of Default (the
preceding clause (ii) being referred to as the “Covenant Defeasance”), but except as specified above, the remainder of this Indenture and the Notes shall be unaffected thereby. The Company may exercise its Legal Defeasance
option notwithstanding its prior exercise of its Covenant Defeasance option. If the Company exercises its Legal Defeasance or its Covenant Defeasance option, the Subsidiary Guarantees in effect at such time shall terminate. 

Upon satisfaction of the conditions set forth herein (including the receipt by the Trustee of an Officers’ Certificate and an Opinion of
Counsel stating that all conditions precedent to the discharge of such obligations have been satisfied) and upon request and expense of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company
terminates. 
 (c) Notwithstanding the provisions of Sections 8.1(a) and (b) to the extent relating to a Legal Defeasance, the
Company’s Obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.8, 2.9, 2.10, 2.11, 3.12, 3.13, 3.14, 7.7 and 7.8 and in this Article VIII shall survive until the Notes have been paid in full. Thereafter, and in the case of the satisfaction of
discharge of this Indenture pursuant to Section 8.1(a), the Company’s obligations in Sections 7.7, 8.4 and 8.5 shall survive. 

  
 96 

 SECTION 8.2 Conditions to Defeasance. 

In order to exercise either Legal Defeasance or Covenant Defeasance: 

(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 thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the
principal of, and premium, if any, on and interest on the outstanding Notes on the stated maturity or on the applicable Redemption Date, as the case may be, and the Company must specify whether the Notes are being defeased to their stated maturity
or to a particular Redemption Date; 
 (2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee
an Opinion of Counsel in the United States 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 Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel in the United
States 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 has occurred and is 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), and the granting of Liens to secure such borrowings); 

(5) such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of the Guarantors is a party or by which the Company or any of the Guarantors is bound, or
if such breach, violation or default would occur, which is not waived as of, and for all purposes, on and after, the date of such deposit; 

  
 97 

 (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 the Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others;
and 
 (7) the Company must deliver to the Trustee an Officers’ Certificate, stating that all conditions precedent set
forth in clauses (1) through (6) of this paragraph have been complied with; and 
 (8) the Company must deliver to the
Trustee an Opinion of Counsel, stating that all conditions precedent set forth in clauses (2), (3) and (5) of this paragraph have been complied with; provided that the opinion with respect to the condition precedent set forth in clause
(5) may be limited to a review of instruments certified in an Officers’ Certificate as being all the material instruments (other than this Indenture) to which the Company is a party or by which the Company is bound. 

SECTION 8.3 Application of Trust Money. The Trustee shall hold in trust all money or Government Securities (including proceeds
thereof) deposited with it pursuant to this Article VIII. It shall apply the deposited money and the money from Government Securities through the Paying Agent and in accordance with this Indenture and the Notes to the Holders of the Notes of all
sums due in respect of the payment of principal of, and accrued interest on, the Notes. 
 SECTION 8.4 Repayment to the Company.
The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money, Government Securities or other securities held by them upon payment of all the Obligations under this Indenture. 

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by
them for the payment of principal of or interest on the Notes that remains unclaimed by the Holders thereof for two years, and, thereafter, Noteholders entitled to the money must look only to the Company for payment as unsecured general creditors
unless an abandoned property law designates another Person, and the Trustee and the Paying Agent shall have no further liability with respect to such money. 

SECTION 8.5 Indemnity for Government Securities. The Company shall pay and shall indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against deposited Government Securities or the principal and interest received on such Government Securities. This Section 8.5 will survive as provided in Section 8.2(c) herein and the resignation or
removal of the Trustee. 
 SECTION 8.6 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or Government
Securities in accordance with this Article VIII 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 obligations of the
Company and each Guarantor under this Indenture, the Notes and the Subsidiary Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to
apply all such money or Government Securities in accordance with this Article VIII; provided, however, that, if the Company or the Guarantors have 

  
 98 

 
made any payment of principal or interest on any Notes because of the reinstatement of their obligations, the Company or Guarantors, as the case may be, 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
Trustee’s rights under this Article VIII shall survive termination of this Indenture. 
 ARTICLE IX 

AMENDMENTS

(4) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely

Subsidiary Guarantees or the Security Documents (which intent will be certified to the Trustee in an Officers’ Certificate); 

(7) to provide for the issuance of additional Notes and related Subsidiary Guarantees (and the grant of security for the
benefit of the additional Notes and related guarantees) in accordance with the limitations set forth in this Indenture;

or any release of Collateral that becomes effective as set forth in this Indenture, any of the Security Documents; 
 (10) to
add additional secured parties to the extent Liens securing obligations held by such parties are permitted under this Indenture, any of the Security Documents; 

(11) to mortgage, pledge, hypothecate or grant a security interest for the benefit of the Trustee and the Holders of the Notes
as additional security for the payment and performance of the Company’s and any Guarantor’s obligations under this Indenture, in any property, or assets, including any of which are required to be mortgaged, pledged or hypothecated, or in
which a security interest is required to be granted to the Trustee or the Collateral Agent in accordance with the terms of this Indenture or otherwise; 

(12) to provide for the succession of any parties to the Security Documents (and other amendments that are administrative or
ministerial in nature) in connection with an amendment, renewal, extension, substitution, refinancing, restructuring, replacement, supplementing or other modification from time to time of any agreement in accordance with the terms of this Indenture
and the relevant Security Document; and 
 (13) to make any change not materially adverse to the Holders of the Notes in
order to facilitate entry into the ABL Facility or Junior Lien Documents 
 SECTION 9.2 With Consent of Holders. The Company,
the Guarantors and the Trustee may amend or supplement the Notes Documents without notice to any Noteholder but with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including consents obtained in
connection with a tender offer or exchange offer for the Notes). Subject to the provisions of Section 6.4, any past default or compliance with the provisions of this Indenture, the Notes or the Subsidiary Guarantees may be waived with the
consent of the Holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes), in each case in addition to any required consent of holders of
other Priority Lien Obligations required with respect to any amendment or waiver under any Notes Document. However, without the consent of each Noteholder affected, an amendment, supplement or waiver may not: 

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

(2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to
the redemption of the Notes (except provisions relating to minimum required notice of optional redemption); provided, however, that any purchase or repurchase of Notes, including pursuant to Sections 3.5 or 3.9 shall not be deemed a
redemption of the Notes; 

  
 100 

 (3) reduce the rate of or extend the time for payment of interest on any
Note; 
 (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 such Note; 

(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 premium, if any, on, or interest on the Notes; provided, however, that any purchase or repurchase of Notes, including pursuant to Sections 3.5 or 3.9, shall not be deemed be a payment of principal
of, or premium or interest on, the Notes; 
 (7) waive a redemption payment with respect to any Note; provided,
however, that any purchase or repurchase of Notes, including pursuant to Sections 3.5 or 3.9, shall not be deemed a redemption of the Notes; or 

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

In addition, the consent of Holders representing at least two-thirds of the aggregate principal amount
of outstanding Notes will be required to release the Liens for the benefit of the Holders of the Notes on all or substantially all of the Collateral, other than in accordance with the Notes Documents. It shall not be necessary for the consent of the
Holders under this Section 9.2 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 

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

SECTION 9.3 Revocation and Effect of Consents and Waivers. A consent to an amendment, supplement or a waiver by a Holder of a Note
shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note. Any such Holder or subsequent
Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective or otherwise in accordance with any
related solicitation documents. After an amendment, supplement or waiver becomes effective, it shall bind every Noteholder unless it makes a change described in any of clauses (1) through (8) of Section 9.2, and in that case the amendment,
supplement, waiver or other action shall bind each Noteholder 

  
 101 

 
who has consented to it and every subsequent Noteholder that evidences the same debt as the consenting Holder’s Notes. An amendment, supplement or waiver under Section 9.2 shall become
effective upon receipt by the Trustee of the requisite amount of consents, and in relation to any Notes evidenced by Global Notes, such consents need not be in written form and may be evidenced by any electronic transmissions that comport with the
applicable procedures of DTC. 
 The Company may, but shall not be obligated to, fix a record date for the purpose of determining the
Noteholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons
who were Noteholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to
be Holders after such record date. No such consent shall become valid or effective more than 120 days after such record date. 

SECTION 9.4 Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Trustee may
require the Holder of the Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determine, the Company in
exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment. 

SECTION 9.5 Trustee and Collateral Agent to Sign Amendments. The Trustee and, as applicable, the Collateral Agent, shall sign any
amendment or supplement authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee, and, as applicable, the Collateral Agent. If it does, the Trustee
or the Collateral Agent, as applicable, may but need not sign it. In signing any amendment or supplement the Trustee and the Collateral Agent shall be entitled to receive indemnity satisfactory to it and shall be provided with, and (subject to
Sections 7.1 and 7.2) shall be fully protected in conclusively relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment or supplement is authorized or permitted by this Indenture or the Notes Documents, as
applicable, and that such amendment or supplement is the legal, valid and binding obligation of the Company and any Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions
hereof. 
 ARTICLE X 
 GUARANTEE

 SECTION 10.1 Guarantee. Subject to the provisions of this Article X, each Guarantor hereby fully, unconditionally and
irrevocably Guarantees, as primary obligor and not merely as surety, jointly and severally with each other Guarantor, to each Holder of the Notes, to the extent lawful, and the Trustee and the Collateral Agent the full and punctual payment when due,
whether at final maturity, by acceleration, by redemption or otherwise, of the Obligations of the Company under the Notes Documents. Each Guarantor agrees that such Obligations will rank equally in right of payment with other Indebtedness of such
Guarantor, except to the extent such other Indebtedness is subordinate to such Obligations. Each Guarantor further agrees (to the extent permitted by law) that such Obligations may be extended or renewed, in whole or in part, without notice or
further assent from it, and that it will remain bound under this Article X notwithstanding any extension or renewal of any Obligation. 

  
 102 

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

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

Each Guarantor agrees that its Subsidiary Guarantee shall remain in full force and effect until payment in full of all the Obligations or such
Guarantor is released from its Subsidiary Guarantee as provided in Section 10.2. Each Guarantor further agrees that its Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any
part thereof, of principal or interest on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise. 

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

  
 103 

 Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the
Holders, on the other hand, (x) the maturity of the Obligations Guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Obligations Guaranteed hereby and (y) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and
payable by the Guarantor for the purposes of this Subsidiary Guarantee. 
 Each Guarantor also agrees to pay any and all costs and expenses
(including attorneys’ fees and expenses) incurred by the Trustee, the Collateral Agent or the Holders in enforcing any rights under this Section. 

The Subsidiary Guarantee of a Guarantor shall be evidenced by the execution and delivery by the Guarantor of this Indenture or a supplement to
this Indenture pursuant to which such Guarantor becomes a Guarantor. Neither the Company nor the Guarantors shall be required to make a notation on the Notes to reflect any Subsidiary Guarantee or any release, termination or discharge thereof, and
any such notation shall not be a condition to the validity of any Subsidiary Guarantee. 
 SECTION 10.2 Limitation on Liability;
Termination, Release and Discharge. 
 (a) Any term or provision of this Indenture to the contrary notwithstanding, the obligations of
each Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor (including any Guarantees under the Credit Facilities) and after giving effect to any
collections from or payments made by or on behalf of any other Guarantor in respect of the Obligations of such other Guarantor under its Subsidiary Guarantee or pursuant to its contribution Obligations under this Indenture, result in the Obligations
of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

 (b) Each Subsidiary Guarantee by a Guarantor will be automatically released and discharged without the consent of any Holders in
accordance with the following: 
 (1) in connection with any sale or other disposition of all or substantially all of the
properties or assets of such Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Company, if the sale or other disposition does not
violate Section 3.5; 
 (2) in connection with any sale or other disposition of all of the Capital Stock of such
Guarantor to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 3.5; 

(3) if the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this
Indenture; 

  
 104 

 (4) upon Legal Defeasance or Covenant Defeasance upon satisfaction and
discharge of this Indenture pursuant to Article VIII; or 
 (5) upon the liquidation or dissolution of such Guarantor;
provided that no Default or Event of Default has occurred and is continuing. 
 Upon the Company’s request and at its expense,
the Trustee will provide evidence of the release of any Subsidiary Guarantee, provided the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in
this Section 10.2 relating to the release of such Subsidiary Guarantee have been complied with. 
 Any released Guarantor will again
provide a Subsidiary Guarantee if required to do so pursuant to Section 3.11. 
 SECTION 10.3 Right of Contribution. Each
Guarantor hereby agrees that to the extent that any Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the Subsidiary Guarantees, such Guarantor shall be entitled to seek contribution from and
against the Company or any other Guarantor who has not paid its proportionate share of such payment, based on the respective net assets of all the Guarantors at the time of such payment, determined in accordance with GAAP. The provisions of this
Section 10.3 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders, and each Guarantor shall remain liable to the Trustee and the Holders for the full amount Guaranteed by such Guarantor
hereunder. 
 SECTION 10.4 No Subrogation. Notwithstanding any payment or payments made by each Guarantor hereunder, no
Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Company or any other Guarantor or Guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations, nor shall
any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on
account of the Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in
trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to
the Trustee, if required), to be applied against the Obligations. 
 ARTICLE XI 

COLLATERAL AND SECURITY 

SECTION 11.1 Security Interest. 

(a) The due and punctual payment of the principal of, premium on, if any, and interest if any, on the Notes and the Obligations of Guarantors
under the Subsidiary Guarantees, when and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and
interest, if any (to the extent permitted by law), on the Notes and 

  
 105 

 
Subsidiary Guarantees under and performance of all other obligations of the Company and the Guarantors to the Holders of Notes or the Trustee under the Note Documents, according to the terms
hereunder or thereunder (collectively, the “Notes Obligations”), shall be secured by Liens on the Collateral as provided in the Security Documents. The Company and each of the Guarantors consent and agree to be bound by the terms of
the Security Documents to which they are parties, as the same may be in effect from time to time, and agree to perform their obligations thereunder in accordance therewith, and hereby agree that the Collateral Agent shall hold the Collateral on
behalf of and for the benefit of all of the Holders of Notes and the other holders of Priority Lien Obligations. 
 (b) Each Holder of
Notes, by its acceptance thereof and of the Subsidiary Guarantees, consents and agrees to the terms of the Collateral Agency Agreement and the other Security Documents (including, without limitation, the provisions providing for foreclosure and
release of Collateral and amendments to the Security Documents) as the same may be in effect or may be amended from time to time in accordance with their terms and authorizes and appoints UMB Bank, N.A. as the Trustee and as the Collateral Agent.
The Trustee hereby authorizes and appoints UMB Bank, N.A. as Collateral Agent and each Holder of Notes and the Trustee direct the Collateral Agent to enter into the Security Documents (including any amendments thereto contemplated by the Collateral
Agency Agreement and any security documents to secure additional Priority Lien Debt in accordance with the Collateral Agency Agreement) and to perform its obligations and exercise its rights thereunder in accordance therewith, subject to the terms
and conditions thereof, including, without limitation, the limitations on duties of the Collateral Agent provided in the Collateral Agency Agreement. The Trustee, the Collateral Agent and each Holder of Notes, by accepting the Notes and the
Subsidiary Guarantees, acknowledges that, as more fully set forth in the Security Documents, the Collateral as now or hereafter constituted shall be held for the benefit of all the holders of Priority Lien Obligations, subject to the Collateral
Agency Agreement, and the Lien of this Indenture and the Security Documents is subject to and qualified and limited in all respects by the Collateral Agency Agreement and the Security Documents and actions that may be taken thereunder. 

(c) Subject to the provisions of Article VI and Article VII of this Indenture and the terms of the Security Documents (including any consent
of the Holders required thereunder), the Trustee may direct, on behalf of the Holders of Notes, the Collateral Agent to take all actions it deems necessary or appropriate in order to enforce any of the terms of the Security Documents and the
Collateral Agency Agreement and collect and receive any and all amounts payable in respect of the Notes Obligations of the Company or any Guarantor hereunder. 

SECTION 11.2 Real Estate Mortgages and Filings. 

(a) With respect to any Material Real Property owned by the Company or a Guarantor on the Issue Date, the following items will be delivered to
the Collateral Agent within 120 days thereafter: 
 (1) the Company or the applicable Guarantor shall deliver to the
Collateral Agent, as mortgagee or beneficiary, as applicable, for the ratable benefit of itself and the Holders of the Notes and any future Priority Lien Debt, fully executed counterparts of a Mortgage (together with applicable real estate
subordination and priority agreements 

  
 106 

 
related thereto), together with confirmation from the title insurance company insuring the lien of such Mortgage of completion (or reasonably satisfactory arrangements for the completion) of all
recordings and filings of such Mortgage (and payment of any taxes or fees in connection therewith) as may be necessary to create a valid, perfected Lien with the priority required by the Collateral Agency Agreement, subject to Permitted Liens,
against the property purported to be covered thereby as security for the Priority Lien Obligations; 
 (2) the Collateral
Agent shall have received mortgagee’s title insurance policies in favor of the Collateral Agent, and its successors and/or assigns, in the form necessary, with respect to the property purported to be covered by the applicable Mortgages, to
insure that the interests created by the Mortgages constitute valid Liens thereon (with the priority required by the Collateral Agency Agreement) free and clear of all Liens, defects and encumbrances other than Permitted Liens, provided, however,
unless delivered to the collateral agent in respect of any other Priority Lien Debt, no such title insurance policies will be required to be delivered with respect to any Mortgage where the property encumbered thereby consists primarily of
easements, rights of way, licenses and other similar possessory and use instruments. All such title policies shall be in amounts equal to 110% of the estimated Fair Market Value of the Premises covered thereby, and such policies shall include, to
the extent available at a commercially reasonable premium, all endorsements as shall be reasonably required in transactions of similar size and purpose and shall be accompanied by evidence of the payment in full by the Company or the applicable
Guarantor of all premiums thereon (or that satisfactory arrangements for such payment have been made); 
 (3) an Opinion of
Counsel, from counsel with respect to the Mortgages and fixture filings, that the applicable Mortgage (i) has been duly authorized, executed and delivered by the Company or applicable Guarantor, (ii) is an enforceable agreement against the
Company or applicable Guarantor, as the case may be, and (iii) is in form sufficient to create a valid Lien with respect to the Material Real Estate Property described in the Mortgage; 

(4) the Company shall, or shall cause the Guarantors to, deliver to the title company such filings, surveys (or any updates or
affidavits that the title company may reasonably require in connection with the issuance of the title insurance), fixture filings and such other documents, instruments, certificates, agreements and/or other documents as reasonably required to
perfect the Collateral Agent’s security interest; and 
 (5) the title insurance company shall have received, with
respect to the applicable Mortgage, such affidavits, certificates, information (including publicly-available financial data) and instruments of indemnification (including a so-called “gap”
indemnification) as shall be reasonably requested by the title insurance company to issue the mortgagee’s title insurance policies contemplated above. 

  
 107 

 (b) With respect to any Material Real Property acquired by the Company or a Guarantor after
the Issue Date which is required to be mortgaged to the Collateral Agent within 120 days of the date of acquisition: 
 (1)
the Company or the applicable Guarantor shall deliver to the Collateral Agent, as mortgagee or beneficiary, as applicable, for the ratable benefit of itself and the Holders of the Notes and any future Priority Lien Debt, fully executed counterparts
of Mortgages (together with applicable real estate subordination and priority agreements related thereto), in accordance with the requirements of the Indenture and/or the Security Documents duly executed by such the Company or such Guarantor,
together with confirmation from the title insurance company insuring the lien on such Mortgage of the completion (or reasonably satisfactory arrangements for the completion) of all recordings and filings of such Mortgage (and payment of any taxes or
fees in connection therewith) as may be necessary to create a valid, perfected Lien with the priority required by the Collateral Agency Agreement, subject to Permitted Liens, against the property purported to be covered thereby as security for the
Priority Lien Obligations; 
 (2) the Collateral Agent shall have received mortgagee’s title insurance policies in favor
of the Collateral Agent, and its successors and/or assigns, in the form necessary, with respect to the property purported to be covered by the applicable Mortgages, to insure that the interests created by the Mortgages constitute valid Liens thereon
(with the priority required by the Collateral Agency Agreement) free and clear of all Liens, defects and encumbrances other than Permitted Liens, provided, however, unless delivered to the collateral agent in respect of any other Priority Lien Debt,
no such title insurance policies will be required to be delivered with respect to any Mortgage where the property encumbered thereby consists primarily of easements, rights of way, licenses and other similar possessory and use instruments. All such
title policies shall be in amounts equal to 110% of the estimated Fair Market Value of the Premises covered thereby, and such policies shall include, to the extent available at a commercially reasonable premium, all endorsements as shall be
reasonably required in transactions of similar size and purpose and shall be accompanied by evidence of the payment in full by the Company or such Guarantor of all premiums thereon (or that satisfactory arrangements for such payment have been made);
and 
 (3) the Company shall, or shall cause the Guarantors to, deliver to the title company such filings, surveys (or any
updates or affidavits that the title company may reasonably require in connection with the issuance of the title insurance policies), fixture filings and such other documents, instruments, certificates, agreements and/or other documents necessary to
comply with clauses (1) and (2) above and to perfect the Collateral Agent’s security interest and (with the priority required by the Collateral Agency Agreement) Lien in such acquired covered Premises, together with local counsel opinions
in the jurisdiction where each property subject to the Mortgage is located, with respect to the Mortgage, fixture filings and other matters reasonably requested by the Collateral Agent. 

  
 108 

 SECTION 11.3 After Acquired Collateral; Further Assurances; Other Agreements
with respect to Collateral. 
 (a) Subject to the provisions of the Security Documents, upon the acquisition by the Company or any
Guarantor after the Issue Date of any assets (other than Excluded Property), including, but not limited to, any Material Real Property or any equipment or fixtures which constitute accretions, additions or technological upgrades to the equipment or
fixtures or any other tangible assets that, in any such case, form part of the Collateral, the Company or such Guarantor shall execute and deliver (i) with regard to any Material Real Property, the items described under Section 11.2(b)
above within the time periods specified therein, and (ii) to the extent required by the Security Documents, any information, documentation, financing statements or other certificates and opinions of counsel as may be necessary to vest in the
Collateral Agent a perfected security interest, subject only to Permitted Liens, in such after-acquired property and to have such after-acquired property added to the Collateral, and thereupon all provisions of the Indenture relating to the
Collateral shall be deemed to relate to such after-acquired property to the same extent and with the same force and effect; provided, however, that if granting such security interest requires the consent of a third party, the Company or such
Guarantor, as the case may be, shall use commercially reasonable efforts to obtain such consent. If the Company or Guarantor is unable to obtain such consent after using its commercially reasonable efforts, the Company or Guarantor shall deliver an
Officers’ Certificate to the Collateral Agent certifying it was unable to obtain such consent after using commercial reasonable efforts, and the Collateral Agent may conclusively rely on such Officers’ Certificate without any investigation
or inquiry. 
 (b) The Company and the Guarantors shall execute any and all further documents, financing statements, agreements and
instruments, and take all further action that may be required under applicable law, or that the Collateral Agent or the Trustee may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the security
interests and Liens created or intended to be created by the Security Documents in the Collateral. In addition, to the extent required under the Indenture or any of the Security Documents, from time to time, the Company and the Guarantors will
reasonably promptly secure the obligations under the Indenture and Security Documents by pledging or creating, or causing to be pledged or created, perfected security interests and Liens with respect to the Collateral perfected to the extent
required by the Security Documents. Such security interests and Liens will be created under the Security Documents and, to the extent necessary, other security agreements and other instruments and documents in form and substance reasonably
satisfactory to the Collateral Agent. Without limiting the foregoing, at any time and from time to time, the Company and each of the Guarantors shall promptly execute, acknowledge and deliver such Security Documents, instruments, certificates,
financing statements, notices and other documents, and take such other actions as shall be reasonably required, or that the Collateral Agent may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be
conferred, in each case as contemplated by the Security Documents for the benefit of the Priority Lien Secured Parties; provided, that no such Security Document, instrument or other document shall be materially more burdensome upon the Company and
the Guarantors than the Priority Lien Documents executed and delivered (or required to be executed and delivered after the date of this Indenture) by the Company and the Guarantors in connection with the Issue Date. 

(c) Notwithstanding anything to the contrary herein, neither the Company nor any of the Guarantors shall be required to take any actions under
any laws outside of the United States to grant, perfect or provide for the enforcement of any security interest. The Company and the Guarantors shall be required to deliver to the Collateral Agent originals of the certificates of title or ownership
for the motor vehicles (and any other equipment covered by certificates of title or ownership) owned by it, with the Collateral Agent listed as lienholder therein; provided, however, that such requirement shall not apply with respect to any
such titled vehicles and other 

  
 109 

 
equipment that individually have a book value (as determined by the Company in good faith) of less than $25,000. Moreover, delivery of certificates of title or ownership documentation to the
Collateral Agent as described above shall be done, with respect to the motor vehicles and other equipment owned by the Company and the Guarantors as of the Issue Date, as promptly as reasonable practicable but in no event later than 12 months after
the Issue Date, and with respect to motor vehicles and other equipment acquired by the Company and the Guarantors after the Issue Date, within 90 days after such acquisition. 

(d) The Company will deliver to the Trustee copies of all documents delivered to the Collateral Agent pursuant to the Security Documents. 

(e) To the extent any grant of security required hereby would require the execution and delivery of a Security Document, the Company or such
Guarantor shall execute and deliver such Security Document, together with related certificates and opinions with respect thereto, on substantially the same terms as the Security Documents covering Collateral owned by the Company and Guarantors on
the Issue Date. 
 (f) Unless an Event of Default shall have occurred and be continuing and subject to certain terms and conditions, the
Company and the Guarantors are entitled to exercise any voting and other consensual rights pertaining to all Capital Stock pledged pursuant to the Security Documents and to remain in possession and retain exclusive control over the Collateral (other
than as set forth in the Security Documents), to operate the Collateral, to alter or repair the Collateral and to collect, invest and dispose of any interest or income thereon. 

(g) Except as provided in the Security Documents, the Company and the Guarantors shall maintain the Collateral that is material to the conduct
of their respective businesses in good and insurable operating order, condition and repair, and shall pay all real estate and other taxes (except such as are contested in good faith and by appropriate negotiations or proceedings), and maintain in
full force and effect all material permits, except, in each case, where the failure to effect such payment or maintain such permits is not adverse in any material respect to the Holders of Notes. 

(h) The Company will not, will not permit any of its Restricted Subsidiaries to, (i) take or omit to take any action which would
materially adversely affect or impair the Liens in favor of the Collateral Agent for the benefit of the Holders of the Notes and any future Priority Lien Debt with respect to the Collateral, (ii) grant to any Person, or permit any Person to
retain (other than the Collateral Agent), any Liens in the Collateral, other than Permitted Liens or (iii) enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or
otherwise acquire or retire any Indebtedness of any Person in a manner that conflicts with the Indenture, the Notes, the Subsidiary Guarantees or the Security Documents. The Company and each Guarantor will, at its sole cost and expense, execute and
deliver all such agreements and instruments as necessary, or as the Trustee or the Collateral Agent reasonably requests, to more fully or accurately describe the assets and property intended to be Collateral or the Obligations intended to be secured
by the Security Documents. 

  
 110 

 SECTION 11.4 Information Regarding Collateral. 

(a) The Company will furnish to the Collateral Agent, with respect to the Company or any Guarantor, promptly (and in any event within 30 days
of such change) written notice of any change in such Person’s (i) legal name, (ii) jurisdiction of organization or formation, (iii) type of legal entity or (iv) Organizational Identification Number. The Company and the
Guarantors agree not to effect or permit any change referred to in the preceding sentence unless all filings have been made under the Uniform Commercial Code and any other applicable laws that are required pursuant to the Security Documents in order
to maintain the perfection and priority of the Collateral Agent’s Lien in the Collateral and for the Collateral to be made subject to the Lien of the Collateral Agent under the Security Documents in the manner and to the extent required by the
Indenture or any of the Security Documents and shall take all necessary action so that such Lien is perfected with the same priority as immediately prior to such change to the extent required by the Security Documents. The Company also agrees
promptly to notify in writing the Collateral Agent if any material portion of the Collateral is damaged, destroyed or condemned. 
 (b) Each
year, within 120 days after the end of the preceding fiscal year, the Company shall deliver to each of the Trustee and the Collateral Agent a certificate of a financial officer setting forth the information required pursuant to the schedules
required by the Security Documents or confirming that there has been no change in such information since the date of the prior annual financial statements and an Opinion of Counsel as to continuation of perfected security interests. The Trustee and
the Collateral Agent will have no obligation to maintain or monitor the perfection of liens. 
 SECTION 11.5 The Collateral Agency
Agreement. 
 This Article XI and the provisions of each other Security Document are subject to the terms, conditions and benefits set
forth in the Collateral Agency Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Collateral Agency Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder
in accordance with the terms therewith. Each Holder of Notes, by its acceptance of the Notes (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Collateral Agency Agreement and (b) authorizes
and instructs the Collateral Agent on behalf of each Holder to enter into the Collateral Agency Agreement as Collateral Agent on behalf of such Holders. 

SECTION 11.6 Release of Liens in Respect of Notes. 

The Liens on the Collateral securing the Notes will automatically and without the need for any further action by any Person be released: 

(1) in whole or in part, as applicable, as to all or any portion of property subject to such Liens which has been taken by
eminent domain, condemnation or other similar circumstances; 
 (2) in whole upon satisfaction and discharge of the Indenture
or a Legal Defeasance or Covenant Defeasance pursuant to Article VIII; 
 (3) in part, as to any property constituting
Collateral that (a) is sold, transferred or otherwise disposed of by either of the Company or any Guarantor (other than to the Company or another Restricted Subsidiary) in a transaction not prohibited by this Indenture or the Security Documents
at the time of such sale, transfer or disposition or (b) is owned or at any time acquired by a Guarantor that has been released from its Subsidiary Guarantee in accordance with this Indenture, concurrently with the release of such Subsidiary
Guarantee; 

  
 111 

 (4) in whole or in part, as applicable, with the requisite consent of
Holders the Notes as described in Section 9.2; or 
 (5) in accordance with the applicable provisions of the Security
Documents and the Collateral Agency Agreement. 
 To the extent required by the Indenture for the release of properties that constitute
Collateral, the Company and each Guarantor will furnish to the Trustee and the Collateral Agent, prior to each proposed release of such Collateral pursuant to the Security Documents and this Indenture, an Officer’s Certificate and an Opinion of
Counsel to the effect that such release is permitted by this Indenture and the Security Documents. Upon compliance by the Company or any Guarantor, as the case may be, with the conditions precedent set forth above, the Trustee or the Collateral
Agent shall, upon request from and at the expense of the Company or the Guarantors, as applicable, promptly cause to be released and reconveyed to the Company or the Guarantors, as the case may be, the released Collateral. 

SECTION 11.7 Collateral Agent. 

(a) The Collateral Agent will hold (directly or through co-trustees or agents) and, subject to the
terms of the Collateral Agency Agreement, will be entitled to enforce all Liens on the Collateral created by the Security Documents. 
 (b)
Except as provided in the Collateral Agency Agreement or as directed by an Act of Required Priority Lien Debtholders (as defined in the Collateral Agency Agreement) in accordance with the Collateral Agency Agreement, the Collateral Agent will not be
obligated: 
 (1) to act upon directions purported to be delivered to it by any Person; 

(2) to foreclose upon or otherwise enforce any Lien; or 

(3) to take any other action whatsoever with regard to any or all of the Security Documents, the Liens created thereby or the
Collateral 
 SECTION 11.8 Maintenance of Insurance. 

(a) The Company and the Guarantors will maintain insurance with respect to the Collateral, covering casualty, hazard, theft, malicious
mischief, flood and other risks, with insurers, in such amounts, and with such coverages and deductibles as are at the time of placing such insurance customary for companies similarly situated and which are available at commercially reasonable
rates. All proceeds under each policy covering Collateral shall be payable to the Collateral Agent as a lender loss payee. From time to time upon request, the Company shall deliver to the Collateral Agent the originals or certified copies of its
insurance policies. Each policy shall include satisfactory endorsements that (i) provide for not less than 30 days prior notice to the 

  
 112 

 
Collateral Agent of termination, lapse or cancellation of such insurance, (ii) with respect to insurance covering Collateral, name the Collateral Agent as lender’s loss payee, and
(iii) specify that the interest of the Collateral Agent shall not be impaired or invalidated by any act or negligence of the Company or any Guarantor or the owner of the property, nor by the occupation of the premises for purposes more
hazardous than are permitted by the policy. If the Company fails to provide and pay for any insurance, the Collateral Agent may, at its option, but shall not be required to, procure the insurance and charge the Company therefor. The Company agrees
to deliver to the Collateral Agent, promptly as rendered, copies of all reports made to insurance companies. 
 (b) In addition to the
insurance required under clause (a) with respect to Collateral, maintain insurance with insurers, with respect to the properties and business of the Company and the Guarantors, of such type (including product liability, workers’
compensation, larceny, embezzlement, or other criminal misappropriation insurance), in such amounts, and with such coverages and deductibles as are at the time of placing such insurance customary for companies similarly situated and which are
available at commercially reasonable rates.

Senior Secured Notes due 2023 
 1. Interest 

Basic Energy Services, Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred
to, being herein called the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. 

The Company will pay interest semiannually on April 15 and October 15 of each year commencing April 15, 2019. Interest on the
Notes will accrue from the most recent date to which interest has been paid on the Notes or, if no interest has been paid, from October 2, 2018. The Company shall pay interest on overdue principal, and it shall pay interest on overdue
installments of interest, at the rate borne by the Notes to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

2. Method of Payment 
 By no later than
11:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Company shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal,
premium, if any, and/or interest. The Company will pay interest (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the April 1 or October 1 next preceding the Interest Payment Date
even if Notes are cancelled, repurchased or redeemed after the record date and on or before the Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company will pay principal, premium, if any, and
interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and interest) will be made
by the transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depositary. The Company will make all payments in respect of a Definitive Note (including principal, premium, if any, and
interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Notes may also be made, at the Company’s option, by wire transfer to a U.S. dollar account maintained by the
payee with a bank in the United States if the Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due
date for payment (or such other date as the Trustee may accept in its discretion). 
 3. Paying Agent and Registrar 

Initially, UMB Bank, N.A. (the “Trustee”) will act as Trustee, Paying Agent and Registrar. The Company may appoint and change
any Paying Agent or Registrar without notice to any Noteholder. The Company or any of its Restricted Subsidiaries may act as Paying Agent or Registrar. 

4. Indenture 
 The Company has issued the
Notes under an Indenture dated as of October 2, 2018 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), between the Company and the Trustee. The terms of the Notes
include those stated in the Indenture. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all terms and provisions of the Indenture, and Noteholders are referred to the
Indenture for a statement of those terms. In the event of a conflict between the Indenture and this Note, the Indenture shall govern. 

  
 A-3 

 The Notes are senior secured obligations of the Company. The aggregate principal amount of
Notes that may be authenticated and delivered under the Indenture is unlimited, subject to compliance with the covenants in the Indenture. This Note is one of the 10.75% Senior Secured Notes due 2023 referred to in the Indenture. The Notes include
(i) $300,000,000 aggregate principal amount of the Company’s 10.75% Senior Secured Notes due 2023 issued under the Indenture on October 2, 2018 (herein called “Initial Notes”) and (ii) if and when issued, additional
10.75% Senior Secured Notes due 2023 of the Company that may be issued from time to time under the Indenture subsequent to October 2, 2018 (herein called “Additional Notes”) as provided in Section 2.1(a) of the Indenture.
The Initial Notes and Additional Notes are treated as a single class of securities under the Indenture. 
 5. Redemption 

The Notes will be subject to Redemption as set forth in Article V of the Indenture. 

The Company and its Subsidiaries may acquire Notes by means other than a redemption or required repurchase, whether by tender offer, open
market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws. 
 6. Guarantees; Security 

The Notes will be fully and unconditionally guaranteed by the Guarantors, and the Notes and the Subsidiary Guarantees will be secured by
first-priority liens on the Collateral, pursuant to the Security Documents. Reference is made to the Indenture and the Notes Documents for terms relating to such security, including the release, termination and discharge thereof. Enforcement of the
Security Documents is subject to the Collateral Agency Agreement. 
 7. Repurchase Provisions 

(a) If a Change of Control occurs, unless the Company has exercised its right to redeem all of the Notes as described under paragraph 5 above
or another of the exceptions set forth in Section 3.9 of the Indenture applies, each Holder will have the right to require the Company to repurchase from each Holder all or any part (equal to $2,000 or an integral multiple of $1,000 in excess
thereof) of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date
to receive interest due on the relevant Interest Payment Date) as provided in, and subject to the terms of, the Indenture. 
 (b) If the
Company or any Restricted Subsidiary consummates an Asset Sale, the Company may be obligated to make an Asset Sale Offer to all Holders and all holders of certain other Priority Lien Debt, on the terms and subject to the conditions in
Section 3.5. 

  
 A-4 

 8. Denominations; Transfer; Exchange 

The Notes are in registered form without coupons in denominations of principal amount of $2,000 and whole multiples of $1,000 in excess
thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any taxes and
fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Note (A) for a period (1) of 15 days before giving notice of any redemption of Notes or (2) beginning 15 days
before an Interest Payment Date and ending on such Interest Payment Date or (B) selected for redemption, except the unredeemed portion of any Note being redeemed in part. 

9. Persons Deemed Owners 
 The registered
Holder of this Note shall be treated as the owner of it for all purposes. 
 10. Unclaimed Money 

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company for payment as unsecured general creditors unless an abandoned property law
designates another Person and not to the Trustee for payment. 
 11. Defeasance 

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

12. Amendment, Supplement, Waiver 

Subject to certain exceptions set forth in the Indenture, (i) the Notes Documents may be amended or supplemented by the Company, the
Guarantors and the Trustee with the consent of the Holders of a majority in principal amount of the then outstanding Notes and (ii) any default (other than with respect to nonpayment or in respect of a provision that cannot be amended without
the consent of each Noteholder affected) or noncompliance with any provision may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes, in each case in addition to any required consent of holders
of other Priority Lien Obligations required with respect to any amendment or waiver under any Notes Document. Without the consent of any Noteholder, the Company, the Guarantors and the Trustee may amend or supplement the Indenture, the Notes or the
Subsidiary Guarantees in certain respects as provided in the Indenture. 

  
 A-5 

 13. Defaults and Remedies 

If an Event of Default (other than an Event of Default with respect to certain bankruptcy events as provided in the Indenture) occurs and is
continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Notes by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare all the Notes
to be due and payable immediately, including any premium thereon as specified in the Indenture. If an Event of Default with respect to certain bankruptcy events as provided in the Indenture occurs and is continuing, the Notes will become and be
immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. 
 Noteholders may not enforce
the Indenture or the Notes or other Notes Documents except as provided in the Indenture. Subject to the provisions of the Indenture relating to the duties of the Trustee if an Event of Default exists, the Trustee may refuse to enforce the Indenture
or the Notes unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold
from Noteholders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interests. 

14. Trustee Dealings with the Company 

Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 

15. No personal liability of directors, officers, employees and stockholders  

No director, officer, employee, manager, incorporator, member, partner or stockholder or other owner of Capital Stock of the Company or any
Guarantor, as such, will have any liability for any obligations of the Company or the Guarantors under the Notes, the Indenture or the Subsidiary Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder of a Note by accepting the Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 

16. Authentication 
 This Note shall not
be valid until an authorized signatory of the Trustee (or an Authenticating Agent acting on its behalf) manually signs the certificate of authentication on the other side of this Note. 

17. Abbreviations 
 Customary
abbreviations may be used in the name of a Noteholder or an assignee, such as TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (= joint tenants with rights of survivorship and not as tenants in common), CUST (= custodian)
and U/G/M/A (= Uniform Gift to Minors Act). 

  
 A-6 

 18. CUSIP, Common Code and ISIN Numbers 

The Company has caused CUSIP and ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP, Common Code and ISIN numbers, if
applicable, in notices of redemption or purchase as a convenience to Noteholders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption or purchase and reliance may be
placed only on the other identification numbers placed thereon. 
 19. Governing Law 

This Note shall be governed by, and construed in accordance with, the laws of the State of New York. 

20. Copies of Indenture 
 The Company will
furnish to any Noteholder upon written request and without charge to the Noteholder a copy of the Indenture, which has in it the text of this Note and a copy of the other Notes Documents. Requests may be made to:

 21. Patriot
Act

verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to the Indenture agree that they will provide the Trustee with such information as it may
request in order for the Trustee to satisfy the requirements of the Patriot Act.
