and net of the effect of all payments made or received pursuant to Hedging Contracts in respect of interest rates; plus

The Issuers will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency in the Borough of Manhattan, The City of New York, where Notes may be presented for payment (“Paying Agent”). Unless otherwise designated by the Issuers by written notice to the Trustee, each such office or agency shall be the Trustee’s office in the Borough of Manhattan, The City of New York.

The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. Either Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

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

The Issuers initially appoint the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.

Section 2.04Paying Agent to Hold Money in Trust

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

Section 2.05Holder Lists

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

Section 2.06Transfer and Exchange

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

(1)the Issuers deliver to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuers within 120 days after the date of such notice from the Depositary;

(2)the Issuers in their sole discretion determine that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and deliver a written notice to such effect to the Trustee; or

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

Upon the occurrence of either of the preceding events in (1) or (2) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Section 2.07 and Section 2.10. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06, Section 2.07 or Section 2.10, shall be authenticated and

If any mutilated Note is surrendered to the Trustee or the Issuers and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuers will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuers, an indemnity bond must

be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note.

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

Section 2.08Outstanding Notes.

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

If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a “protected purchaser” as defined in Section 8-303 of the Uniform Commercial Code.

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

If the Paying Agent (other than an Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09Treasury Notes

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

Section 2.10Temporary Notes

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

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

Section 2.11Cancellation

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

Section 2.12 Defaulted Interest.

If the Issuers default in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01. The Issuers will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuers will fix or cause to be fixed each such special record date and payment date, provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.13PIK Interest

The Company may elect to pay a portion of the interest payable on the Notes in kind as set forth in the Notes. The Issuers shall deliver a notice to the Trustee, not less than five Business days prior to the record date immediately preceding such interest payment date, setting forth the Issuers’ election to pay cash or PIK Interest with respect to the portion of interest that may be paid in kind as set forth in the Notes with respect to such interest payment date. In the absence of an election notice made by the Issuers as set forth in this Section 2.13 for any interest payment date, interest on the Notes will be payable on such interest payment date as if the Issuers had elected to pay PIK Interest with respect to the portion of interest that may be paid in kind as set forth in the Notes.

Any payment of PIK Interest shall be made in such form and on terms as specified in the Notes, and the Issuers shall and the Trustee may take additional steps as necessary to effect such PIK Payment.

Notwithstanding anything to the contrary, the payment of accrued interest in connection with any redemption or purchase of the Notes as described under Sections 3.07, 3.09, 4.10 or 4.15 or in connection with the final maturity of the Notes will be made solely in cash at the Cash Interest Rate.

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

(2)the redemption date;

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

(4)the redemption price.

Section 3.02Selection of Notes to Be Redeemed or Purchased

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase by lot, unless otherwise required by law or applicable stock exchange or requirements of the Depositary.

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee will promptly notify the Issuers in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof (or amounts of $1.00 or integral multiples of $1.00 in the case of any PIK Notes). Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03Notice of Redemption

Subject to the provisions of Section 4.10 and Section 4.14, at least 30 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail (or, in the case of Notes in global form, pursuant to the Applicable Procedures of the Depositary), a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or Article 11.

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

(1)the redemption date;

(2)the redemption price;

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

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

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

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

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

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

(9)if such redemption or notice is subject to satisfaction of one or more conditions precedent, that, in the Issuers’ discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed.

At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ names and at their expense; provided, however, that the Issuers have delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter time is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04Effect of Notice of Redemption

Once notice of redemption is sent in accordance with Section 3.03, Notes called for redemption become due on the date fixed for redemption, unless the redemption is subject to a condition precedent that is not satisfied or waived. Any redemption or notice of redemption may, at the Issuers’ discretion, be subject to one or more conditions precedent.

Section 3.05Deposit of Redemption or Purchase Price

At least one Business Day prior to the redemption or purchase date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, and accrued interest, if any, on all Notes to be redeemed or purchased on that date (including any PIK Notes or any increased principal amount of Notes sufficient to pay PIK

Interest). The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest, if any, on all Notes to be redeemed or purchased.

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

Section 3.06Notes Redeemed or Purchased in Part

If at any time the Issuers fail to maintain any such required office or agency or fails 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.

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

If:

(1)the Company elects to satisfy its obligations under this covenant with respect to financial information relating to the Company by furnishing financial information relating to a direct or indirect parent of the Company, and such financial information reflects the assets or operations of Subsidiaries of such direct or indirect parent of the Company that are not also Restricted Subsidiaries of the Company, or

(2)the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries and the assets or operations of such Unrestricted Subsidiaries taken as a whole are material to the assets or operations of Company and all of its Subsidiaries taken as a whole, then the quarterly and annual financial information required by Section 4.03(a) through (d) above will include an additional summary presentation, either on the face of the financial statements, in the footnotes thereto, or in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of any direct or indirect parent of the Company and/or the Unrestricted Subsidiaries of the Company, as applicable. The requirement to provide additional summary financial information required by this paragraph will be deemed satisfied if and when such information is posted on the website of the Company or any direct or indirect parent of the Company.

(h)Delivery of reports, information and documents to the Trustee pursuant to this Section 4.03 is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

Section 4.04Compliance Certificate.

(a)The Issuers shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of each Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuers have kept, observed, performed and fulfilled their obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Issuers have kept, observed, performed and fulfilled each and every covenant contained in this Indenture and are not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuers are taking or propose to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of, or premium, if any, or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuers are taking or propose to take with respect thereto.

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

Section 4.05Taxes

Section 4.06Stay, Extension and Usury Laws.

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

Section 4.08Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

(a)The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1)pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; provided that the priority that any series of preferred stock of a Restricted Subsidiary has in receiving dividends or liquidating distributions before dividends or liquidating distributions are paid in respect of common stock of such Restricted Subsidiary shall not constitute a restriction on the ability to pay dividends or make distributions on Capital Stock for purposes of this Section 4.08(a);

(2)make loans or advances to the Company or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Company or any such Restricted Subsidiary to other Indebtedness incurred by the Company or any such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances for purposes of this Section 4.08(a)); or

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

(b)However, the restrictions in Section 4.08(a) will not apply to encumbrances or restrictions existing under or by reason of:

(1)agreements or instruments governing Existing Indebtedness (as in effect on the Issue Date), and any amendments, modifications, restatements, renewals, extensions, increases, supplements, refundings, replacements or refinancings of those agreements or the Indebtedness to which they relate, provided that the encumbrances or restrictions contained in any amendments, modifications, restatements, renewals, extensions, increases, supplements, refundings, replacements or refinancings are, in the reasonable good faith judgment of the Chief Financial Officer of the General Partner, not materially more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the Issue Date;

(2)this Indenture, the Notes (and any Additional Notes), the Note Guarantees, the Collateral Trust Agreement and the Security Documents;

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

replacements or refinancings are, in the reasonable good faith judgment of the Chief Financial Officer of the General Partner, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that, in the case of Indebtedness, the incurrence of such Indebtedness was permitted by the terms of this Indenture;

(5)customary non-assignment provisions in contracts or licenses, easements or leases, in each case, entered into in the ordinary course of business;

(6)mortgage financings, security agreements or purchase money obligations, in each case, for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 4.08(a);

(7)any agreement for the sale or other disposition of the Equity Interests in, or all or substantially all of the properties or assets of, a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending the sale or other disposition;

(8)Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are, in the reasonable good faith judgment of the Chief Financial Officer of the General Partner, not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(9)Liens permitted to be incurred under the provisions of Section 4.12 that limit the right of the debtor to dispose of the assets subject to such Liens;

(10)provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including, but not limited to, agreements entered into in connection with a Restricted Investment) entered into in the ordinary course of business or entered into with the approval of the Company’s Board of Directors, which limitation is applicable only to the assets and properties that are the subject of such agreements;

(11)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;

(12)encumbrances or restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(13)the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred stock is permitted pursuant to Section 4.09 and the terms of such preferred stock do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or

liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital Stock);

(14)obligations under Hedging Contracts permitted under this Indenture;

(15)any agreement or instrument relating to Indebtedness incurred or Capital Stock issued by any Restricted Subsidiary; provided that the encumbrances or restrictions contained in the agreements or instruments governing such Indebtedness or Capital Stock (a) apply only in the event of a payment default or a default with respect to a financial covenant in such agreement or instrument or (b) will not materially affect the Company’s ability to make payments with respect to the principal of, or the interest and premium, if any, on, the Notes, as determined in the reasonable good faith judgment of the Chief Executive Officer or the Chief Financial Officer of the General Partner; and

(16)any other agreement governing Indebtedness permitted to be incurred by Section 4.09 and any amendments, modifications, restatements, renewals, extensions, increases, supplements, refundings, replacements or refinancings of those agreements; provided that the encumbrances or restrictions in such agreements are, in the reasonable good faith judgment of the Chief Financial Officer of the General Partner, not materially more restrictive, taken as a whole, than those contained in this Indenture or the ABL Facility as in effect on the Issue Date.

Section 4.09Incurrence of Indebtedness and Issuance of 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 preferred stock; provided, however, that the Issuers may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any of the Guarantors may incur Indebtedness (including Acquired Debt) or issue preferred stock, if, 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, the Fixed Charge Coverage Ratio of the Company would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b)Notwithstanding the foregoing, the provisions of Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness or issuances of Disqualified Stock or preferred stock, as applicable (collectively, “Permitted Debt”):

(1)the incurrence by the Issuers or any Guarantor of Indebtedness and letters of credit under the ABL Facility, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness 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) does not exceed $50.0 million;

(2)the incurrence by the Issuers or any Guarantor of Indebtedness represented by:

(A)the Notes and the Note Guarantees issued on the Issue Date, and any increase in principal amount of the Notes as a result of a PIK Payment and any PIK Notes issued in respect thereof; and

(B)Priority Lien Debt (including the New First Lien Notes issued on the Issue Date, which shall be deemed to be incurred pursuant to this clause (2)(B); 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 Permitted Refinancing Indebtedness incurred to refinance any Indebtedness incurred pursuant to this clause (2)(B)) does not exceed $50.0 million;

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

(4)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 for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4) at any time; provided that, immediately after giving effect to any such incurrence, the principal amount of all Indebtedness incurred pursuant to this clause (4) and then outstanding does not exceed $35.0 million;

(5)the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value, any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company, or Indebtedness (other than intercompany Indebtedness) or preferred stock of any Restricted Subsidiary, in each case, that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (2), (3), (4), (6), (12), (13) or (16) of this Section 4.09(b) or this clause (5);

(6)the incurrence by the Company or any of its Restricted Subsidiaries of (i) Permitted Refinancing Indebtedness constituting Junior Lien Debt in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value, Existing Unsecured Notes and (ii) Junior Lien Debt;

provided that, immediately after giving effect to any such incurrence under this clause (6)(ii) then outstanding (including all Junior Lien Debt incurred to refinance any Indebtedness incurred under this clause (6)(ii)) does not exceed the greater of (a) $50.0 million and (b) an amount such that after giving effect to such incurrence, the Secured Leverage Ratio would not exceed 4.0 to 1.0;

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

(A)if the Company or any Guarantor is the obligor on such Indebtedness and neither the Company nor a Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case where the Company is the obligor, or the Note Guarantee, in the case where a Guarantor is the obligor; 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 and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary 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 was not permitted by this clause (7);

(8)the incurrence by the Company or any of its Restricted Subsidiaries of (a) Hedging Obligations in the ordinary course of business and not for speculative purposes and (b) Cash Management Obligations in the ordinary course of business;

(9)the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this Section 4.09;

(10)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; and

(B)any sale or other transfer of any such preferred stock to a Person that is neither the Company nor a 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 (10);

(11)the incurrence by the Company or any of its Restricted Subsidiaries of liability in respect of the Indebtedness of any Unrestricted Subsidiary or any Joint Venture

but only to the extent that such liability is the result of the Company’s or any such Restricted Subsidiary’s being a general partner or member of, or owner of an Equity Interest in, such Unrestricted Subsidiary or Joint Venture and not as a guarantor of such Indebtedness; provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (11) and then outstanding does not exceed $25.0 million;

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

(13)the incurrence by any Foreign Subsidiary of Indebtedness that, in the aggregate together with all other Indebtedness of all Foreign Subsidiaries (including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (13)), does not exceed $75.0 million;

(14)the incurrence by the Company or any Restricted Subsidiary 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;

(15)the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness constituting (A) reimbursement obligations with respect to letters of credit; provided that, upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing or (B) any letters of credit outstanding on the Issue Date (whether or not drawn) not to exceed $10.0 million; and

(16)the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness and the issuance by the Company of any Disqualified Stock, provided that, after giving effect to any such incurrence or issuance, the amount of all such Indebtedness and Disqualified Stock incurred or issued pursuant to this clause (16) and then outstanding (including all Permitted Refinancing Indebtedness and Disqualified Stock incurred to extend, refinance, renew, replace, defease, refund, discharge or otherwise retire for value any Indebtedness or Disqualified Stock incurred or issued pursuant to this clause (16)) does not exceed $35.0 million.

(c)Neither the Company nor any of its Restricted Subsidiaries will incur any Indebtedness that is subordinated in right of payment (including via any “first out” collateral proceeds waterfall or similar structure) to the ABL Facility or the First Lien Notes unless such Indebtedness is also subordinated in right of payment to the New Second Lien Notes.

(d)The Company and its Restricted Subsidiaries shall not be permitted to issue Junior Lien Debt secured by Liens that are pari passu with the Liens securing the Notes in a Refinancing of the Existing Unsecured Notes (whether in a single transaction or a series of related transactions) pursuant to clauses (6) and (16) of the definition of “Permitted Debt” that (a) bears an All-In Yield greater than the Notes or (b) has a final maturity date earlier than or a Weighted Average Life to Maturity lesser than the Notes (clause (a) or (b) above, collectively, the “MFN Debt”), in each case, without amending the Notes to provide for an increased interest rate that results in an

equivalent All-In Yield to the MFN Debt, earlier final maturity date or earlier required payments of principal provided for under the terms of the MFN Debt. Within 20 Business Days following the issuance of any MFN Debt, the Company shall amend the indenture and the Notes to provide for the changes to the terms of the Notes set forth in the previous sentence, and any change in the accrual of interest shall be effective as of the date of issuance of the MFN Debt. For the avoidance of doubt, Holders of a majority in aggregate principal amount of the Notes may amend or waive the covenant set forth in this Section 4.09(d).

(e)For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (2) through (16) of Section 4.09(b), or is entitled to be incurred pursuant to Section 4.09(a), the Company will be permitted in its sole discretion to divide, redivide, classify or reclassify such item of Indebtedness on the date of its incurrence, and later divide, redivide, classify or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. The accrual of interest or dividends with respect to preferred stock, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares 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 Section 4.09, provided that, in each such case, the amount thereof is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term. Further, the reclassification of any obligation of the Company or any of its Restricted Subsidiaries as Indebtedness due to a change in accounting principles will not be deemed an incurrence of Indebtedness for purposes of this Section 4.09.

(f)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 utilized, 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 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Section 4.10Asset Sales.

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

(1)the Company or any of its Restricted Subsidiaries, as the case may be, receives consideration (including by way of relief from, or any Person assuming responsibilities for, any liabilities (other than any contingent liabilities)) 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)at least 75% of the consideration received by the Company or its Restricted Subsidiaries in the Asset Sale (considered together on a cumulative basis, with all consideration received by the Company or any of its Restricted Subsidiaries in respect of other Asset Sales consummated since March 22, 2018) is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(A)any liabilities, as shown on the Company’s or any of its Restricted Subsidiaries’ most recent balance sheet, of the Company or such Restricted Subsidiary (other than contingent liabilities and Subordinated Debt) that are assumed or forgiven by the transferee of any such assets pursuant to a novation or indemnity agreement (or other legal documentation with the same effect) that releases the Company or such Restricted Subsidiary from or indemnifies the Company or such Restricted Subsidiary against further liability;

(B)any securities, notes or other obligations received by the Company or any of its Restricted Subsidiaries from such transferee that are, within 90 days after the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(C)any Additional Assets of the kind referred to in clause (2) of Section 4.10(b); and

(D)any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in respect of such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (D) since the date of this Indenture, not to exceed the greater of (i) $15.0 million and (ii) 2.0% of the Company’s Consolidated Net Tangible Assets (with the Fair Market Value of each item of Designated Non-cash Consideration being determined in good faith by the Company at the time received in respect of an Asset Sale, and without giving effect to subsequent changes in value).

(b)Within 365 days after the receipt of any Net Proceeds from Asset Sales or, if the Company or any of its Restricted Subsidiaries has entered into a binding commitment or commitments with respect to any of the actions described in clauses (2) or (3) below, within the later of (x) 365 days after the receipt of any Net Proceeds from Asset Sales and (y) 180 days after

the entering into of such commitment or commitments, the Company or any of its Restricted Subsidiaries may apply an amount equal to the amount of such Net Proceeds at its option to any combination of the following:

(1)to repay, redeem or repurchase (a) any Priority Lien Debt, (b) the Notes or (c) any other Junior Lien Debt; provided that if the Company shall so repay other Junior Lien Debt pursuant to clause (c), the Company shall have also used (or made an offer, in the case of clause (iii) below, with) a portion of such Net Proceeds pro rata in proportion to the amount thereof used to so repay other Junior Lien Debt (based on the respective principal amounts of the Notes and such other Junior Lien Debt prior to such repayment) (the “Pro Rata Amount”) to (i) redeem the Pro Rata Amount of Notes as provided under Section 3.07, (ii) purchase the Pro Rata Amount of Notes that may be repurchased through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or (iii) make an offer to purchase the Pro Rata Amount of Notes pursuant to an offer made to all Holders in accordance with the procedures set forth in Section 4.10(c) for an Asset Sale Offer 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;

(2)in the case of Net Proceeds from Asset Sales other than Collateral, to repay, redeem or repurchase any Senior Debt, including any ABL Debt;

(3)to invest in or acquire Additional Assets; or

(4)to make capital expenditures in respect of a Permitted Business.

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

(c)An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (1) through (4) of Section 4.10(b) will constitute “Excess Proceeds.” Within ten Business Days after the aggregate amount of Excess Proceeds exceeds $30.0 million, the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and other Junior Lien Debt to purchase, prepay or redeem with the Net Proceeds of such Asset Sales the maximum principal amount of Notes and other Junior Lien Debt (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase, prepayment or redemption, subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of repurchase, prepayment or redemption, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any of its Restricted Subsidiaries may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes or other Junior Lien Debt tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and the Trustee or agent for such other Junior Lien Debt to be purchased by lot (unless otherwise required by law), based on the

amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Company so that no Notes or other Junior Lien Debt purchased in part remain outstanding in an unauthorized principal denomination). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(d)Notwithstanding the foregoing paragraphs of this Section 4.10, the sale, conveyance or other disposition of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of Section 4.14 and/or Section 5.01 and not by this Section 4.10.

(e)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 each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.10, or compliance with this Section 4.10 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

(f)In the event that, pursuant to the preceding provisions of this Section 4.10, the Issuers are required to commence an Asset Sale Offer, the Issuers will follow the procedures specified below.

(1)The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other Priority Lien Debt as specified in Section 4.10(c) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

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

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

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

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

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

(E)that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 or integral multiples of $1,000 in excess thereof (or in denominations of $1.00 or integral multiples of $1.00 in the case of any PIK Notes);

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

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

(H)that, if the aggregate principal amount of Notes and other Priority Lien Debt surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other Priority Lien Debt to be purchased by lot (unless otherwise required by law) based on the principal amount of Notes and such other Priority Lien Debt surrendered (with such adjustments as may be deemed appropriate by the Company so that Notes or other Priority Lien Debt purchased in part remains outstanding in an unauthorized principal denomination); and

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

(4)On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.10.

Section 4.11Transactions with Affiliates.

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

(1)the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of the Company, 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; and

(2)the Company delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by either the Conflicts Committee of the Board of Directors of the Company (so long as the members of the Conflicts Committee approving the Affiliate Transaction or series of related Affiliate Transactions are disinterested) or a majority of the disinterested members of the Board of Directors of the Company, if any.

(5)transactions effected in accordance with the terms of agreements that are identified in the Issuers’ Offering Memorandum dated April 17, 2020, in each case as such agreements are in effect on the Issue Date, and any amendment or replacement of any of such agreements so long as such amendment or replacement agreement is no less advantageous to the Company in any material respect than the agreement so amended or replaced;

(6)payment of reasonable fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise) of, and compensation paid to, and indemnity, insurance or other benefits provided on behalf of, officers, directors, employees or consultants of the General Partner, the Company or any of its Restricted Subsidiaries or Affiliates of the Company, including, but not limited to, reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

(10)transactions between the Company or any of its Restricted Subsidiaries and any other Person, a director of which is also on the Board of Directors of the Company or any direct or indirect parent company of the Company, and such common director is the sole cause for such other Person to be deemed an Affiliate of the Company or any of its Restricted Subsidiaries; provided, however, that such director abstains from voting as a member of the Board of Directors of the Company or any direct or indirect parent company of the Company, as the case may be, on any transaction with such other Person; and

(11)(a) guarantees by the Company or any of its Restricted Subsidiaries of performance of obligations of Unrestricted Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money, and (b) pledges by the Company or any of its Restricted Subsidiaries of Equity Interests in Unrestricted

(15)transactions with Unrestricted Subsidiaries, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are, in the aggregate (taking into account all the costs and benefits associated with such transactions), not materially less favorable to the Company and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated person, in the good faith determination of the Company’s Board of Directors or any officer of the Company involved in or otherwise familiar with such transaction, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

Section 4.12Liens.

The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired.

Neither the Company nor any of its Restricted Subsidiaries will incur any Lien that is junior in priority to the Liens securing either the ABL Facility or the First Lien Notes (other than a Lien securing Junior Lien Debt that is pari passu with the Liens securing the Notes) unless such Lien is also junior in priority to the Liens securing the Notes.

Section 4.13Business Activities of Finance Corp.

Finance Corp. will not hold any material assets, become liable for any material obligations, engage in any trade or business, or conduct any business activity, other than the issuance of capital stock to the Company or any of its Restricted Subsidiaries, the incurrence of Indebtedness as a co‑issuer, co-obligor or guarantor of Indebtedness incurred by the Company (including without limitation the Notes) that is permitted to be incurred by the Company under Section 4.09, and activities incidental thereto.

Section 4.14Offer to Repurchase Upon Change of Control.

(a)If a Change of Control occurs, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes as set forth in the Notes and in Section 3.07, 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 of $2,000 (or $1.00 or integral multiples of $1.00 in the case of any PIK Notes)) 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 to make a cash payment (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 repurchase (the “Change of Control Settlement Date”), subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the Change of Control Settlement Date. Within 30 days following any Change of Control, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes as set forth in the Notes and in Section 3.07, 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 properly tendered Notes on the Change of Control Settlement 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. Furthermore, such notice shall state:

(1)that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment;

(2)the Change of Control Payment and the Change of Control Settlement Date;

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

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

(5)that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of

Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Settlement Date;

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

(7)that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof (or $1.00 or integral multiples of $1.00 in the case of any PIK Notes).

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, or compliance with the provisions of this Section 4.14 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.14 by virtue of such compliance.

(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 after such acceptance, the Company will, on the Change of Control Settlement 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 together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

On the Change of Control Settlement Date, the Paying Agent will send 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, however, that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000 (or $1.00 or integral multiples of $1.00 in the case of any PIK Notes). Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Settlement Date, unless the Company defaults in making the Change of Control

Payment. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date.

(c)Notwithstanding any provision to the contrary, 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 time and otherwise in compliance with the requirements set forth in Section 4.14(a) 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) notice of redemption of all outstanding Notes has been given pursuant to Section 3.07 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 repurchase (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 the Alternate Offer. Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, 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.

Section 4.15Additional Note Guarantees.

The Company will cause each Domestic Subsidiary (other than an Excluded Domestic Subsidiary) created or acquired by the Company or one or more of its Restricted Subsidiaries to execute and deliver to the trustee, within 20 Business Days of the date on which such Domestic Subsidiary is created or acquired, a Note Guarantee pursuant to which such Guarantor will unconditionally guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest on the Notes on a senior secured basis; provided that any such Domestic Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor until such time as it ceases to be an Immaterial Subsidiary. Each Domestic Subsidiary that becomes a Guarantor after the date of issuance of the Notes will also become a party to the Collateral Trust Agreement and the Security Documents and will take such actions as are reasonably necessary or advisable to grant the Collateral Trustee for the benefit of the Holders of the Notes and, the Trustee, a Priority Lien in any Collateral held by such Domestic Subsidiary, subject only to Permitted Liens.

Section 4.16Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the

designation and will reduce the amount available for Restricted Payments under Section 4.07 or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

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

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; 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) such Indebtedness is permitted under Section 4.09 calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable four-quarter reference period and (2) no Default or Event of Default would be in existence following such designation.

Section 4.17Termination of Covenants.

If at any time (a) the Notes have an Investment Grade Rating from at least two Rating Agencies, (b) no Default has occurred and is continuing under this Indenture and (c) the Company has delivered to the Trustee an Officers’ Certificate certifying as to the satisfaction of the conditions set forth in the foregoing clauses (a) and (b) of this sentence, the Company and its Restricted Subsidiaries will no longer be subject to the provisions of Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11, Section 4.14 and clause (4) of Section 5.01(a).

(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 Junior 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 $25.0 million ceases to be an enforceable and perfected second-priority Lien, subject only to Permitted Liens; provided further, that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 30 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period;

(B)except as permitted by this Indenture or the relevant Security Documents, any Junior 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 $25.0 million ceases to be an enforceable and perfected second-priority Lien in any material respect, subject to Permitted Liens, and such condition continues for 60 days after written notice by the Trustee or the Collateral Trustee (after the Trustee or Collateral Trustee has received written notice of such cessation from the holders of 25% or more of the aggregate principal amount of the Notes outstanding) 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 Trustee; provided further, that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 30 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period; 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.

Section 6.02Acceleration.

In the case of an Event of Default specified in clause (9) or (10) of Section 6.01, with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary of the Company, all outstanding Notes will become due and payable immediately without further action or notice (subject to applicable law). If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all of the Notes to be due and payable immediately by notice in writing to the Company and, in the case of a notice by such Holders, also to the Trustee specifying the respective Event of Default and that it is a notice of acceleration.

Upon any such declaration, the Notes shall become due and payable immediately.

Section 6.03Other Remedies.

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

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

Section 6.04Waiver of Past Defaults.

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

Section 6.05Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy

available to either the Trustee or the Collateral Trustee, as applicable, or exercising any trust or power conferred on either the Trustee or the Collateral Trustee, as applicable. However, either the Trustee or Collateral Trustee, as applicable, may refuse to follow any direction that conflicts with law, this Indenture or other Notes Documents that either the Trustee or Collateral Trustee, as applicable, determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve either the Trustee or the Collateral Trustee in personal liability; (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any action or forbearance is unduly prejudicial to such holders).

Section 6.06Limitation on Suits.

Subject to the provisions of Section 7.01, in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any Holders of the Notes unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest, if any, when due, no Holder may pursue any remedy with respect to this Indenture or the Notes 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 aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

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

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

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

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, and premium, if any, and interest on, the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), 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 6.08Collection Suit by Trustee.

100

If an Event of Default specified in clause (1) or (2) of Section 6.01 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of the principal, premium, if any, or interest remaining unpaid on the Notes and interest on overdue principal and premium, if any, and to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall, subject to the terms of the Collateral Trust Agreement, pay out the money in the following order:

First:

(i) to the Trustee, its agents and attorneys for amounts due under Section 7.07, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection and (ii) to the Collateral Trustee, all fees, expenses, indemnities and other amounts payable to the Collateral Trustee under the Collateral Trust Agreement, this Indenture and other Notes Documents;

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

101

to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and

Third:

to the Issuers 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 6.11Undertaking for Costs.

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

ARTICLE 7
TRUSTEE

Section 7.01Duties of Trustee.

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

(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 or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions to determine whether they conform to the requirements of this Indenture.

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

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

102

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

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

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

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

Section 7.02Rights of Trustee.

(a)The Trustee may conclusively rely upon any document reasonably believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

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

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

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

(g)The Trustee and the Collateral Trustee shall in all cases be fully protected in acting, or in refraining from acting, under this Indenture, Collateral Trust Agreement, the Intercreditor Agreement, or the Security Documents in accordance with a request of the Holders of a majority in aggregate principal amount of the then outstanding Notes, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Holders of the Notes. In the event the Trustee or the Collateral Trustee receives inconsistent or conflicting requests and indemnity from two or more groups of Holders of the then outstanding Notes, each representing less than a

103

majority in aggregate principal amount of the then outstanding Notes, the Trustee, in its sole discretion, may determine what action, if any, shall be taken and the Trustee may, in its discretion, take other actions.

(h)No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights or powers under this Indenture at the request of any Holders, unless such Holder has offered to the Trustee reasonable indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in connection with its compliance with such request.

(i)The Trustee shall have no duty or obligation to monitor the Issuers’ compliance with the terms of this Indenture, the Collateral Trust Agreement, the Intercreditor Agreement, or the Security Documents or any documents related hereto or to ascertain or inquire as to the observance, performance of any covenants, conditions or agreements of the Issuers except as expressly set forth in this Indenture.

(j)The permissive right of the Trustee or the Collateral Trustee to do things enumerated in this Indenture shall not be construed as a duty. The Trustee or the Collateral Trustee shall be under no obligation to institute any suit, or to undertake any proceeding under this Indenture, or to enter any appearance or in any way defend in any suit in which it may be made defendant, or to take any steps in the execution of the trusts hereby created or in the enforcement of any rights and powers hereunder, until it shall be indemnified to its satisfaction against any and all costs and expenses, outlays and counsel fees and other anticipated disbursements, and against all liability except to the extent determined by a court of competent jurisdiction to have been caused solely by its own negligence or willful misconduct.

(k)The rights, privileges, protections, immunities and benefits given to the Trustee or the Collateral Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee or the Collateral Trustee in each of its capacities hereunder (including but not limited to as Agent), and each agent, custodian and other person employed to act hereunder.

(l)The Trustee shall not be responsible for delays or failures in performance resulting from acts beyond its control, including without limitation acts of God, strikes, lockouts, riots, acts of war or terror, epidemics, governmental regulations, pandemics, fire, communication line failures, computer viruses or failures, power failures, earthquakes or other disasters; it being understood that the Trustee shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

Section 7.03Individual 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 Issuers or any Affiliate of the Issuers with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest after a Default has occurred or is continuing, it must eliminate such conflict within 90 days

104

or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10 and Section 7.11.

Section 7.04Trustee’s Disclaimer.

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

Section 7.05Notice of Defaults.

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

The Trustee will not be deemed to have notice of any Default or Event of Default, except Events of Default under clause (1) or (2) of Section 6.01, unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event that is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

Section 7.06Reports by Trustee to Holders of Notes.

(a)Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain outstanding, the Trustee will send to the Holders of Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted).

(b)A copy of each report at the time it is sent to the Holders of Notes will be mailed by the Trustee to the Issuers.

Section 7.07Compensation and Indemnity.

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

105

(b)The Issuers and the Guarantors, jointly and severally, will indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuers and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence, bad faith or willful misconduct. The Trustee will notify the Issuers and the Guarantors promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers and the Guarantors will not relieve the Issuers or any of the Guarantors of their obligations hereunder unless the failure to notify the Issuers or the Guarantors impairs any Issuer’s or Guarantor’s respective ability to defend such claim. Such Issuer or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuers will pay the reasonable fees and expenses of such counsel. Neither Issuer nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c)The obligations of the Issuers and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture.

(d)To secure the Issuers’ and the Guarantors’ payment obligations in this Section 7.07 and the other Notes Documents (for the fees, expenses and indemnities payable to the Collateral Trustee), the Trustee and the Collateral Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee or the Collateral Trustee, except that held in trust to pay principal of and interest on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture.

(e)When the Trustee incurs expenses or renders services after an Event of Default specified in clause (9) or (10) of Section 6.01 occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.08Replacement of Trustee.

(a)A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

(b)The Trustee may resign in writing at any time and be discharged from the trust hereby created only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if:

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

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

106

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

(4)the Trustee becomes incapable of acting.

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

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

(e)If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f)A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

107

Section 7.09Successor Trustee by Merger, etc.

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

Section 7.10Eligibility; Disqualification.

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

This Indenture will always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b).

Section 7.11Preferential Collection of Claims Against Company.

The Trustee is subject to 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) to the extent indicated therein. The Trustee hereby waives any right to set off any claim that it may have against the Issuers in any capacity (other than as Trustee and Paying Agent) against any of the assets of the Issuers held by the Trustee; provided, however, that if the Trustee is or becomes a lender of any other Indebtedness permitted hereunder to be pari passu with the Notes, then such waiver shall not apply to the extent of such Indebtedness.

ARTICLE 8
LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuers may at any time, at the option of their respective Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or Section 8.03 be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02Legal Defeasance and Discharge.

Upon the Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.02, each Issuer and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations

108

under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

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

(2)the Issuers’ obligations with respect to the Notes under Section 2.04, Section 2.06, Section 2.07, Section 2.10 and Section 4.02;

(3)the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers’ and the Guarantors’ obligations in connection therewith; and

(4)the Legal Defeasance provisions of this Article 8.

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

Section 8.03Covenant Defeasance.

Upon the Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.03, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04, be released from each of their obligations under Section 4.03, Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11, Section 4.12, Section 4.13, Section 4.14, Section 4.15, Section 4.16, Section 4.17 and Section 5.01(a)(4) with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (such release and termination hereinafter referred to as “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04, clauses (3) through (7) of Section 6.01 and, only with respect to Subsidiaries of the Company, clauses (9) and (10) of Section 6.01 will not constitute Events of Default.

8.04Conditions to Legal or Covenant Defeasance.

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

109

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

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

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

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

(4)no Default or Event of Default 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 Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Issuers or any of the Guarantors is a party or by which the Issuers or any of the Guarantors is bound;

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

110

(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 Section 8.04 have been complied with; and

(8)the Company must deliver to the Trustee an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions, qualifications and exclusions), stating that all conditions precedent set forth in clauses (2), (3) and (5) of this Section 8.04 have been complied with; provided that the Opinion of Counsel with respect to clause (5) of this Section 8.04 may be to the knowledge of such counsel.

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

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

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

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

Section 8.06Repayment to Company.

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

111

or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.07Reinstatement.

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

ARTICLE 9
AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01Without Consent of Holders of Notes.

Notwithstanding Section 9.02, without the consent of any Holder of Notes, the Issuers, the Guarantors, the Trustee and the Collateral Trustee may amend or supplement this Indenture, the Notes, the Note Guarantees or the Security Documents (subject, in the case of the Security Documents, to any further requirements in the Collateral Trust Agreement):

(5)to conform the text of this Indenture, the Notes, the relevant Security Documents or the Note Guarantees to any provision of the “Description of the New Second Lien Notes” section of the Issuers’ Offering Memorandum dated April 17, 2020, to the extent that such provision in that “Description of the New Second Lien Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Notes, the relevant Security Documents or the Note Guarantees, which intent may be evidenced by an Officers’ Certificate to that effect;

112

(6)to provide for the issuance of Additional Notes and related Note Guarantees (and the grant of security for the benefit of the Additional Notes and related Note Guarantees) or PIK Notes or to increase the outstanding principal amount of the Notes, in each case in accordance with the limitations set forth in this Indenture;

(7)to add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee, in each case as provided in this Indenture;

(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;

(13)with respect to the Security Documents, as provided in the Collateral Trust Agreement;

(14)to make any change not adverse to the Holders of the Notes in order to facilitate entry into the ABL Documents, Priority Lien Documents or other Junior Lien Documents;

(16)in the event of an issuance of MFN Debt, to increase the interest rate or provide for earlier final maturity or required payments of principal pursuant to Section 4.09(d).

113

Upon the request of the Issuers accompanied by resolutions of their respective Boards of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee and the Collateral Trustee of the documents described in Section 7.02, the Trustee and the Collateral Trustee will join with the Issuers and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee and the Collateral Trustee will not be obligated to enter into such amended or supplemental indenture that affects either the Trustee’s or the Collateral Trustee’s own rights, duties or immunities under this Indenture or otherwise.

Section 9.02With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Section 4.10 and Section 4.14), the Notes, the Note Guarantees and the Security Documents with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes and subject, in the case of the Security Documents, to any further requirements in the Collateral Trust Agreement), and, subject to Section 6.04 and Section 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes, the Note Guarantees or the Security Documents may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes and subject, in the case of the Security Documents, to any further requirements in the Collateral Trust Agreement).

Upon the request of the Issuers accompanied by resolutions of their respective Boards of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02, the Trustee will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

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

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. Subject to Section 6.04 and Section 6.07, the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class may waive

114

compliance in a particular instance by the Company with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non‑consenting Holder):

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

(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; provided, however, that any purchase or repurchase of Notes, including pursuant to Section 4.10 and Section 4.14, shall not be deemed a redemption of the Notes;

(3)reduce the rate of or change the time for payment of interest, including default interest, on any Note;

(4)waive a Default or Event of Default in the payment of principal of, or interest or premium, 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 currency other than that stated in the Notes;

(6)make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, or interest or premium 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 Section 4.10 and Section 4.14, shall not be deemed a redemption of the Notes;

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

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

Any amendment to, or waiver of, the provisions of this Indenture or any Security Document that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Notes (other than in accordance with the Notes Documents) will require the consent of the Holders of at least 66-2∕3% in aggregate principal amount of the Notes then outstanding.

Section 9.03[Reserved].

Section 9.04Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note

115

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

The Issuers may fix a record date for determining which Holders must consent to such amendment, supplement or waiver. If the Issuers fix a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.05, or (ii) such other date as the Issuers shall designate.

Section 9.05Notation on or Exchange of Notes.

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

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

Section 9.06Trustee and Collateral Trustee to Sign Amendments, etc.

The Trustee and the Collateral Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee or the Collateral Trustee, as applicable. No Issuer may sign an amended or supplemental indenture until its Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee and the Collateral Trustee will be entitled to receive and (subject to Section 7.01, in the case of the Trustee) will be fully protected in relying upon, in addition to the documents required by Section 12.04, an Officers’ Certificate and an Opinion of Counsel each stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and the other Notes Documents.

ARTICLE 10
NOTE GUARANTEES

Section 10.01Guarantee.

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

(1)the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and

116

interest on the overdue principal of, premium, if any, and interest on, the Notes, if lawful (subject in all cases to any applicable grace period provided herein), and all other obligations of the Issuers to the Holders, the Trustee or the Collateral Trustee hereunder or under any other Notes Document will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

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

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

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

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

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

117

Section 10.02Limitation on Guarantor Liability.

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

Section 10.03Execution and Delivery of Note Guarantee Notation.

To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

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

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

In the event that either Issuer or any of its Restricted Subsidiaries creates or acquires any Domestic Restricted Subsidiary after the Issue Date, if required by Section 4.15, the Company will cause such Domestic Restricted Subsidiary to comply with the provisions of Section 4.15 and this Article 10, to the extent applicable.

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

Except as otherwise provided in Section 10.05, no Guarantor may sell or otherwise dispose of, in one or more related transactions, all or substantially all of its properties or assets to, or consolidate with or merge with or into (regardless of whether such Guarantor is the surviving Person), another Person, other than the Company or another Guarantor, unless:

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

118

(2)either:

(A)(i) such Guarantor is the surviving Person of such consolidation or merger or (ii) 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 all the obligations of such Guarantor under the Notes and this Indenture (including its Note Guarantee) pursuant to a supplemental indenture satisfactory to the Trustee; or

(B)such transaction or series of transactions does not violate the provisions of Section 4.10.

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Except as set forth in Article 4 and Article 5, and notwithstanding clauses (A) and (B) immediately above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05Releases.

The Note Guarantee of a Guarantor will be released automatically and without the need for further action by any Person:

(1)in connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate the provisions of Section 4.10;

(2)in connection with any sale or other disposition of the Capital Stock of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate the provisions of Section 4.10 and the Guarantor ceases to be a Restricted Subsidiary as a result of such sale or other disposition;

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

(4)upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 or satisfaction and discharge of this Indenture in accordance with Article 11;

119

(5)upon the liquidation or dissolution of such Guarantor, provided that no Default or Event of Default occurs as a result thereof or has occurred or is continuing;

(6)upon such Guarantor consolidating with, merging into or transferring all of its properties or assets to the Company or another Guarantor and, as a result of or in connection with such transaction, such Guarantor dissolves or otherwise ceases to exist;

(7)at such time as such Guarantor constitutes an Immaterial Subsidiary; or

(8)as provided in Article 9.

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

ARTICLE 11
SATISFACTION AND DISCHARGE

Section 11.01Satisfaction and Discharge.

This Indenture will be satisfied and discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified in this Indenture), and the Security Documents, insofar as they relate to the rights of Holders, will cease to be of further effect with respect to the Notes, when:

(1)either:

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

(B)all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the sending of a notice of redemption or otherwise or will become due and payable within one year and either an Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal of, or interest and premium, if any, on the Notes to the date of maturity or redemption;

(2)in respect of clause (B) of Section 11.01(1), no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event

120

of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which either Issuer or any Guarantor is a party or by which either Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and, in each case, the granting of Liens to secure such borrowings);

(3)the Issuers have, or any Guarantor has, paid or caused to be paid all sums payable by them under this Indenture; and

(4)the Issuers have delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be.

In addition, the Issuers must deliver to the Trustee (a) an Officers’ Certificate, stating that all conditions precedent set forth in clauses (1) through (4) of this Section 11.01 have been satisfied and (b) an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and qualifications), stating that the condition precedent set forth in clause (4) of this Section 11.01 has been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to clause (B) of Section 11.01(1), the provisions of Section 11.02 and Section 8.06 will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02Application of Trust Money.

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

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 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 Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01; provided that if the Issuers have made any payment of principal of, premium, if any, or interest, if any, on, any Notes because of the reinstatement of its obligations, the Issuers 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 Issuers, any Guarantor, the Trustee or the Collateral Trustee, by notice to the others, may designate additional or different addresses for subsequent notices or communications.

All notices and communications (other than those sent to Holders) will be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if electronically transmitted; when receipt acknowledged, if transmitted by facsimile; or the next Business Day after timely delivery to a courier, if sent by overnight air courier guaranteeing next day delivery.

Any notice or communication to a Holder, when the Notes are in the form of Definitive Notes, will be mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Registrar. Any notice or communication to a Holder, when the Notes are in the form of Global Notes, will be sent pursuant to Applicable Procedures. Any notice or communication will also be so sent to any Person described in TIA § 313(c), to the extent required by the TIA. Failure to send a notice or communication to a Holder or any defect in it will not affect its sufficiency with respect to other Holders.

If a notice or communication is mailed or otherwise sent in the manner provided above within the time prescribed, it is duly given, regardless of whether the addressee receives it (other than with respect to notices or communications by facsimile or electronic transmission, which will be deemed to be duly given when receipt is acknowledged or when answered back, respectively).

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver will be the equivalent of such notice. Waivers of notice by Holders will be filed with the Trustee, but such filing will not be a condition precedent to the validity of any action taken in reliance on such waiver.

If the Issuers send a notice or communication to Holders, they will send a copy to the Trustee, the Collateral Trustee and each Agent at the same time.

All notices, approvals, consents, requests and any communications hereunder must be in writing (provided that any communication sent to Trustee hereunder must be in the form of a document that is signed manually or by way of a digital signature provided by a digital signature provider as specified in writing to Trustee by an Officer of the Company), in English.

Notwithstanding the foregoing, the Trustee shall have the right to accept and act upon instructions or directions pursuant to this Indenture sent in the form of a manually signed (or by way of a digital signature provided by a digital signature provider as specified in writing to Trustee by an Officer of the Company) document by unsecured e-mail, facsimile transmission or other similar unsecured electronic methods, provided, however, that the Issuer shall provide to the Trustee an incumbency certificate listing designated persons with the authority to provide such

123

instructions and containing specimen signatures of such designated persons, which incumbency certificate shall be amended whenever a person is to be added or deleted from the listing. If the Issuers elect to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method, using digital signatures or otherwise) and the Trustee in its discretion elects to act upon such instructions, the Trustee's understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee's reliance upon and compliance with such instructions notwithstanding that such instructions conflict or are inconsistent with a subsequent written instruction. The Issuers agree to assume all risks arising out of the use of the use of using digital signatures and electronic methods to submit instructions and directions to the Trustee, including, without limitation, the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties.

Section 12.03Communication by Holders of Notes with Other Holders of Notes.

Holders may communicate with other Holders with respect to their rights under this Indenture or the Notes. The Issuers, the Trustee, the Registrar and anyone else shall have the protection of TIA § 312(c).

ARTICLE 13
COLLATERAL AND SECURITY

Section 13.01 Security Interest.

(a)The due and punctual payment of the Obligations on the Notes and the Obligations of the Guarantors under the Note 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, the Note Guarantees and performance of all other obligations of the Issuers and the Guarantors to the Holders, the Collateral Trustee or the Trustee under the Notes Documents, according to the terms hereunder or thereunder, are secured, as provided in the Security Documents. Each of the Issuers 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. Each of the Issuers and each of the Guarantors hereby agree that the Collateral Trustee shall hold the Collateral (directly or through co-trustees or agents) on behalf of and for the benefit of all of the Holders and the other holders of Priority Lien Obligations.

(b)Each Holder, by its acceptance thereof and of the Note Guarantees, consents and agrees to the terms of the Collateral Trust Agreement, the Intercreditor Agreement, if any, and the 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 U.S. Bank National Association as the Trustee and the Collateral Trustee. Each Holder authorizes and directs the Collateral Trustee to enter into the Notes Documents (including any amendments thereto contemplated by Section 7.1 of the Collateral Trust Agreement and any Security Documents to secure additional Priority Lien Debt in accordance with Section 3.8 of the Collateral Trust Agreement) and the Intercreditor Agreement, if any, and to perform its obligations and exercise its rights thereunder in accordance therewith, subject to the terms and conditions thereof,

126

including, without limitation, the limitations on duties of the Collateral Trustee provided in Section 5.12 of the Collateral Trust Agreement. The Trustee, the Collateral Trustee and each Holder, by accepting the Notes and the Note Guarantees of the Guarantors, 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 Trust Agreement and the Intercreditor Agreement, if any, the Collateral Trustee and the Trustee, and the Lien of this Indenture and the Security Documents is subject to and qualified and limited in all respects by the Collateral Trust Agreement, the Intercreditor Agreement, if any, and the Security Documents and actions that may be taken thereunder.

(c)Neither the Collateral Trustee nor the Trustee shall be responsible for and neither of them makes any representation as to the legality, effectiveness or sufficiency of any Security Documents or for the creation, perfection, priority or protection of any lien securing the Issuers’ obligations hereunder. Neither the Collateral Trustee nor the Trustee shall be responsible for the sufficiency or accuracy of any financing statements initially filed to perfect security interests granted under this indenture, or for the filing of any financing or continuation statement or recording any documents or instruments in any public office at any time or otherwise for perfecting or maintaining the perfection of any lien or security interest in the trust estate; it being understood that the Issuers shall be obligated to make such filings on behalf of the Collateral Trustee.

Section 13.02 Post-Issue Date Collateral Requirements.

(a)Within 120 days following the Issue Date (or such longer period as the Collateral Trustee may agree), the Issuers shall, or shall cause the applicable Guarantor to execute and deliver to the Collateral Trustee (or to the Priority Lien Collateral Trustee as bailee on behalf of the Collateral Trustee in accordance with the Intercreditor Agreement) 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 Trustee listed as lienholder therein, in each case to the extent required by the Security Agreement.

(b)Any Security Documents entered into after the Issue Date shall be substantially in the form of the corresponding security document securing the Priority Lien Obligations, or to the extent there is no such corresponding security document, the corresponding security documents securing the Priority Lien Obligations in place on the Issue Date, in each case, with such changes as reasonably necessary to reflect the terms of the Collateral Trust Agreement and the Intercreditor Agreement, if any, and with such deletions or modifications of representations, warranties and covenants as are customary with respect to security documents establishing Liens securing publicly traded debt securities, all as certified to the Collateral Trustee pursuant to an Officers’ Certificate and Opinion of Counsel.

Section 13.03 Maintenance of Collateral; Further Assurances.

(a)The Issuers 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. The Issuers and the Guarantors 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 and insurance in amounts that insures against such losses and risks as are

127

reasonable for the type and size of the business of the Issuers and the Guarantors as determined in good faith by an Officer of the Company, except, in each case, where the failure to effect such payment or maintain such permits or insurance coverages is not adverse in any material respect to the Holders of Notes.

(b)To the extent required under this Indenture or any of the Security Documents, the Issuers and the Guarantors shall, at their sole expense, 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 Trustee 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 this Indenture or any of the Security Documents, from time to time, the Issuers and the Guarantors will reasonably promptly secure the obligations under this 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 Trustee. The Issuers shall deliver or cause to be delivered to the Trustee and Collateral Trustee all such instruments and documents to evidence compliance with this Section 13.03. The Issuers agree to provide evidence to the Trustee and Collateral Trustee as to the perfection (to the extent required by the Security Documents) and priority status of each such security interest and Lien. Notwithstanding anything to the contrary herein or in the Security Documents, in no event shall the Issuers and the Guarantors be required to execute and deliver any control agreements in favor of the Collateral Trustee or the Trustee with respect to any deposit accounts or security accounts.

Section 13.04 After-Acquired Property.

Subject to the provisions of the Security Documents, upon the acquisition by the Issuers or any Guarantor after the Issue Date of any assets (other than ABL Collateral or 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 working capital assets that, in any such case, form part of the Collateral and that are not automatically subject to a perfected security interest under the Security Documents, such Issuer or Guarantor shall (i) with regard to any Material Real Property, execute and deliver the items described under Section 13.06(b) hereof within 90 days (or such longer period as the Collateral Trustee may agree) after the date of acquisition of the applicable asset, (ii) with regard to any other asset constituting Collateral, grant Liens on such property in favor of the Collateral Trustee (and, to the extent such grant would require the execution and delivery of a Security Document, such Issuer or Guarantor shall execute and deliver such Security Document on substantially the same terms as the Security Documents covering Collateral owned by the Issuers and Guarantors on the Issue Date including, with respect to personal property, execution of a supplement to the applicable Security Documents) within 60 days (or such longer period as the Collateral Trustee may agree) after the date of acquisition of the applicable asset and (iii) in the case of the foregoing clauses (i) 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 Trustee a perfected security interest, subject only to Permitted Liens, in such after-

128

acquired property and to have such after-acquired property added to the Collateral, and thereupon all provisions of this 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.

Section 13.05 Impairment of Security Interest.

The Issuers will not, and the Company 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 Trustee for the benefit of the Holders of the Notes and any future Junior Lien Debt with respect to the Collateral, (ii) grant to any Person, or permit any Person to retain (other than the Collateral Trustee), 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 this Indenture, the Notes, the Note Guarantees or the Security Documents. Each Issuer and 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 Trustee 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.

Section 13.06 Real Estate Mortgages and Filings.

(a)With respect to any Material Real Property owned by an Issuer or a Guarantor on the Issue Date, the following items will be delivered to the Collateral Trustee within 120 days thereafter (or such longer period as the Collateral Trustee may agree):

(1)the Issuer or applicable Guarantor shall deliver to the Collateral Trustee, as mortgagee or beneficiary, as applicable, for the ratable benefit of itself and the Holders of the Notes and any future Junior Lien Debt, fully executed counterparts of a Mortgage (together with applicable real estate subordination and priority agreements related thereto) and reasonably satisfactory evidence 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 Trust Agreement, subject to Permitted Liens, against the property purported to be covered thereby as security for the Junior Lien Obligations;

(2)the Collateral Trustee shall have received mortgagee’s title insurance policies in favor of the Collateral Trustee, 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 Trust 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 Junior 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

129

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 Issuer or the applicable Guarantor of all premiums thereon (or that satisfactory arrangements for such payment have been made);

(3)an Opinion of Counsel, from local counsel in the jurisdiction where each property subject to the Mortgages is required by the Collateral Trust Agreement is located, with respect to the Mortgages and fixture filings, that the applicable Mortgage (i) has been duly authorized, executed and delivered by the applicable Issuer or Guarantor, (ii) is an enforceable agreement against the applicable Issuer or Guarantor, as the case may be, and (iii) creates a valid, perfected Lien with respect to the Material Real Property described in the Mortgage;

(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; and

(6)with respect to items (1)-(5) above, the Collateral Trustee shall have no duty or obligation to review the contents thereof and shall receive such items solely as a repository on behalf of the Holders.

(b)With respect to any Material Real Property acquired by an Issuer or a Guarantor after the Issue Date which is required to be mortgaged to the Collateral Trustee within 120 days after the date of acquisition (or such longer period as the Collateral Trustee may agree):

(1)the applicable Issuer or Guarantor shall deliver to the Collateral Trustee, as mortgagee or beneficiary, as applicable, for the ratable benefit of itself and the Holders of the Notes and any future Junior Lien Debt, fully executed counterparts of Mortgages (together with applicable real estate subordination and priority agreements related thereto), in accordance with the requirements of this Indenture and/or the Security Documents duly executed by such Issuer or Guarantor, together with reasonably satisfactory evidence 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 Trust Agreement, subject to Permitted Liens, against the property purported to be covered thereby as security for the Junior Lien Obligations;

130

(3)the Issuers shall, or shall cause the Guarantors to, deliver to the Collateral Trustee or the title company, as applicable, 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 Trustee’s security interest and (with the priority required by the Collateral Trust 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 Collateral Trustee, in each instance in form and substance reasonably satisfactory to the Collateral Trustee; and

(4)with respect to items (1)-(3) above, the Collateral Trustee shall have no duty or obligation to review the contents thereof and shall receive such items solely as a repository on behalf of the Holders.

Section 13.07 Intercreditor Agreement.

(a)Reference is made to the Intercreditor Agreement. Each holder of any Junior Lien Obligations, by its acceptance of such Junior Lien Obligations (i) consents to the subordination of Liens provided for in the Intercreditor Agreement, (ii) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement and (iii) authorizes and instructs the Junior Lien Representative on behalf of each Junior Lien Secured Party (as defined in the Intercreditor Agreement) to enter into the Intercreditor Agreement as Junior Lien Representative (as defined in the Intercreditor Agreement) on behalf of such Junior Lien Secured Parties (as defined in the Intercreditor Agreement). The foregoing provisions are intended as an inducement to the lenders under the Priority Lien Documents to extend credit to the Company and such lenders are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement.

131

(b)This Article 13 and the provisions of each other Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor Agreement. Each of the Issuers and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof. Each Holder, by its acceptance of the Notes authorizes and instructs the Trustee on behalf of each Holder to enter into the Intercreditor Agreement as Junior Lien Representative on behalf of such Holders as Junior Lien Secured Parties (. In addition, each Holder authorizes and instructs the Collateral Trustee to enter into any amendments or joinders to the Intercreditor Agreement, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Debt or Junior Lien Debt and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness thereto.

Section 13.08 Collateral Trust Agreement.

This Indenture, including this Article 13, and the provisions of each other Security Document are subject to the terms, conditions and benefits set forth in the Collateral Trust Agreement. Each of the Issuers and each Guarantor consents to, and agrees to be bound by, the terms of the Collateral Trust 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, 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 Trust Agreement and (b) authorizes and instructs the Collateral Trustee on behalf of the Holders of the Notes and each other holder of Priority Lien Obligations to enter into the Collateral Trust Agreement as Collateral Trustee on behalf of such holders of Priority Lien Obligations and to take such actions in accordance with the terms of the Collateral Trust Agreement as may be required pursuant to the terms of the Collateral Trust Agreement. In addition, each Holder authorizes and instructs the Collateral Trustee to enter into any amendments or joinders to the Collateral Trust Agreement, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Obligations and add other parties (or any authorized agent or trustee therefor) holding such Indebtedness thereto.

Section 13.09 Release of Liens on the Collateral.

(a)The Collateral Trustee’s Liens upon the Collateral will no longer secure the Notes or other Obligations outstanding under this Indenture (but not necessarily any other Priority Lien Debt), and the right of the Holders to the benefits and proceeds of the Collateral Trustee’s Liens on the Collateral will automatically and without the need for any further action by any Person (other than notice of such release to the Collateral Trustee, but the failure to deliver such notice shall not affect such release) terminate and be discharged:

(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 or which has become (and only to the extent it continues to constitute) Excluded Property;

(4)in whole or in part, as applicable, with the consent of Holders of (i) 66-2/3% or more in aggregate principal amount of then outstanding Notes if releasing all or substantially all Collateral and (ii) 50% or more in aggregate principal amount of then outstanding Notes if releasing less than all or substantially all Collateral (in each case, including without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, Notes);

(5)in part, in accordance with the applicable provisions of the Security Documents and the Collateral Trust Agreement;

(6)to the extent any lease is Collateral, upon termination of such lease;

(8)as described in Section 9.02 hereof.

(b)Each of the releases described in clauses (1) through (7) of Section 13.09(a) (other than clause (4)) shall be effected by the Collateral Trustee without the consent of the Holders or any action on the part of the Trustee.

(c)Upon compliance by either of the Issuers or any Guarantor, as the case may be, with the conditions precedent set forth above, the Trustee or the Collateral Trustee shall promptly cause to be released and reconveyed to the Issuers or the Guarantors, as the case may be, the released Collateral.

133

Section 13.10 Collateral Account.

The Collateral Trustee is authorized to receive any funds for the benefit of the Holders and the other secured parties distributed under, and in accordance with, the Collateral Trust Agreement, the Intercreditor Agreement, if any, and the other Security Documents, and to make further distributions of such funds to the Holders and (as applicable) the other secured parties according to the provisions of this Indenture, the Collateral Trust Agreement, the Intercreditor Agreement and the other Security Documents.

Sectin 13.11 Information Regarding Collateral.

The Issuers and the Guarantors agree to deliver all filings necessary under the Uniform Commercial Code and any other applicable laws that are required in the Security Documents in order for the Collateral to be made subject to the Lien of the Collateral Trustee under the Security Documents in the manner and to the extent required by this 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 Issuers also agree promptly to notify in writing the Collateral Trustee if any material portion of the Collateral is damaged, destroyed or condemned.

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

(1)INTEREST. CSI Compressco LP, a Delaware limited partnership (the “Company”), and CSI Compressco Finance Inc., a Delaware corporation (together with the Company, the “Issuers”), jointly and severally promise to pay interest on the principal amount of this Note at the rate set forth below until maturity. The Issuers will pay interest semi‑annually in arrears on April 1 and October 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be ___________, _____. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate equal to the then applicable interest rate on the Notes; they will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods), from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

Interest on the Notes will be payable (1) the annual rate of 7.250% payable in cash, plus (2) at the election of the Issuers the annual rate of (i) 2.750% payable in cash (together with the annual rate set forth in clause (1), the “Cash Interest Rate”) or (ii) 3.500% payable by increasing the principal amount of the outstanding Notes represented by one or more Global Notes or, with respect to Definitive Notes represented by individual certificates, if any, by issuing additional “PIK Notes” in certificated form, in each case rounding up to the nearest $1.00 (such increased principal amount or additional PIK Notes, the “PIK Interest” and each payment of PIK Interest, a “PIK Payment”). In the absence of an interest payment election made by the Issuers as set forth in this paragraph, interest on the Notes will be payable as if the Issuers had elected to pay PIK Interest with respect to the portion of interest payable pursuant to clause (2) of this paragraph.

Any PIK Notes issued in certificated form will be dated as of the date of the applicable Interest Payment Date and will bear interest from and after such date. Following an increase in the principal amount of the outstanding Notes as a result of a PIK Payment, the Notes will accrue interest on such increased principal amount from and after the related Interest Payment Date of such PIK Payment. References herein and in the Indenture to the

A-3

“principal amount” of the Notes include any increase in the principal amount of the outstanding Notes as a result of a PIK Payment. On any Interest Payment Date on which the Issuers pay PIK Interest with respect to a Global Note, the principal amount of such Global Note will increase by an amount equal to the interest payable, rounded up to the nearest $1.00, to be allocated for the credit of the Holders pro rata in accordance with their interests and rounded to the nearest $1.00 in accordance with the procedures of DTC.

(2)METHOD OF PAYMENT. The Issuers will pay interest on the Notes (except defaulted interest), if any, to the Persons who are registered Holders of Notes at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Issuers maintained for such purpose within or without the City and State of New York, or, at the option of the Issuers, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, premium, if any, and interest on, all Global Notes and all other Notes the Holders of which will have provided to the Issuers or the Paying Agent wire transfer instructions to an account in the United States of America. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

At all times, PIK Interest on the Notes will be payable: (i) with respect to Notes represented by one or more Global Notes registered in the name of, or held by, DTC (or any successor depositary) or its nominee on the relevant record date, by increasing the principal amount of the outstanding Global Notes, effective as of the applicable Interest Payment Date, by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest $1.00) at the request of the Issuers to authenticate or increase the Global Note and (ii) with respect to Definitive Notes, if any, by issuing PIK Notes in certificated form, dated as of the applicable Interest Payment Date, in an aggregate principal amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest whole dollar), and the Trustee will, at the request of the Issuers, authenticate and deliver such PIK Notes in certificated form for original issuance to the Holders on the relevant Record Date, as shown by the records of the register of Holders.

Notwithstanding anything to the contrary, the payment of accrued interest in connection with any redemption or purchase of the Notes as described under Sections 3.07, 3.09, 4.10 or 4.15 of the Indenture or in connection with the final maturity of the Notes will be made solely in cash at the Cash Interest Rate.

(3)PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers may change any Paying Agent or Registrar without notice to any Holder; provided, however, that the Issuers shall at all times maintain a Paying Agent in the Borough of

A-4

Manhattan, The City of New York. Either Issuer or any Subsidiary may act in any such capacity.

(4)INDENTURE. The Issuers issued the Notes under an Indenture dated as of June 12, 2020 (the “Indenture”) among the Issuers, the Guarantors, the Trustee and the Collateral Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured obligations of the Issuers. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. The Notes include the Initial Notes, any PIK Notes and any Additional Notes issued pursuant to the Indenture.

(5)OPTIONAL REDEMPTION.

(a)Prior to April 1, 2023, the Company may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes outstanding under the Indenture (which may include Additional Notes) with an amount of cash not greater than the amount of the net cash proceeds from one or more Equity Offerings at a redemption price equal to 110.000% of the principal amount thereof, plus accrued and unpaid interest on the Notes redeemed to, but not including, the redemption date (subject to the rights of Holders of record 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 the Notes issued on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains outstanding after each such redemption; and

(2)

the redemption occurs within 180 days after the closing of such Equity Offering.

(c)On and after April 1, 2023, the Company may redeem all or a part of the Notes, from time to time, at the following redemption prices (expressed as a percentage of the principal amount) plus accrued and unpaid interest on the Notes redeemed to, but not including, the applicable redemption date (subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period beginning on April 1 of the years indicated below:

A-5



Year	Redemption Price
2023	107.500%
2024	105.000%
2025	100.000%

(d)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 set forth in Section 4.14(c) of the Indenture) 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 the purchase pursuant to the Change of Control Offer or Alternate Offer described in Section 4.14 of the Indenture, 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 on the Notes that remain outstanding, to the date of redemption (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).

(e)Unless the Company defaults in the payment of the redemption price, interest, if any, will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

(6)REPURCHASE AT THE OPTION OF HOLDER.

(a)If there is a Change of Control, each Holder will have the right, except as provided below and in the Indenture, to require the Company to make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000 (or $1.00 or integral multiples of $1.00 in the case of any PIK Notes)) of that Holder’s Notes at a purchase price 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, subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will send a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. The Company will not be required to make a Change of Control Offer upon a Change of Control, if (i) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in Section 4.14(a) of the 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, (ii) notice of redemption of all outstanding Notes has been given pursuant to the Indenture unless and until there is a default in payment of the applicable redemption price, or (iii) in connection with or in contemplation of any Change of Control, the Company has made an offer

A-6

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 the Alternate Offer.

(b)If the Company or a Restricted Subsidiary consummates any Asset Sales, within ten Business Days of each date on which the aggregate amount of Excess Proceeds exceeds $30.0 million, the Issuers will commence an offer (an “Asset Sale Offer”) to all Holders of Notes and other Priority Lien Debt to purchase, prepay or redeem with the Net Proceeds of such Asset Sales the maximum principal amount of Notes and other Junior Lien Debt (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase, prepayment or redemption, in accordance with the procedures set forth in the Indenture and subject to the rights of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any of its Restricted Subsidiaries may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes or other Junior Lien Debt tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and the Trustee or agent for such other Junior Lien Debt to be purchased by lot (unless otherwise required by law). Holders of Notes that are the subject of an offer to purchase will receive notice of an Asset Sale Offer from the Company prior to any related purchase, prepayment or redemption date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

(7)NOTICE OF OPTIONAL REDEMPTION. Notices of optional redemption will be mailed by first-class mail (or in the case of Notes in the form of Global Notes, pursuant to the applicable procedures of DTC) at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof (or in denominations of $1.00 or integral multiples of $1.00 in the case of any PIK Notes).

(8)DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 or an integral multiple of $1,000 in excess thereof; provided that PIK Payments may result in Notes being issued in denominations of $1.00 and integral multiples of $1.00. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require a Holder to pay any taxes and fees required by law or permitted

A-7

by the Indenture. The Issuers need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuers need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

(9)PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

(10)Security and Collateral. The Notes will be entitled to the benefits of certain Collateral pledges for the benefit of the Holders pursuant to the terms of the Security Documents, subject to the rights of holders of certain Indebtedness under the Intercreditor Agreement, if any. Reference is hereby made to the Security Documents for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Company, the Guarantors, the Collateral Trustee, the Trustee and the Holders. The Company agrees, and each Holder by accepting a Note agrees, to the provisions contained in the Security Documents and the Indenture and authorizes the Collateral Trustee and the Trustee to give them effect and appoints the Collateral Trustee as attorney-in-fact for such purpose.

(11)AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Notes, the Note Guarantees or the Security Documents may be amended or supplemented with the consent of the Holders of a majority in principal amount of the then outstanding Notes and Additional Notes, if any, voting as a single class (subject, in the case of the Security Documents, to any further requirements in the Collateral Trust Agreement), and any existing Default or Event of Default or compliance with any provision of the Indenture, the Notes, the Note Guarantees or the Security Documents may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes and Additional Notes, if any, voting as a single class (subject, in the case of the Security Documents, to any further requirements in the Collateral Trust Agreement). Without the consent of any Holder of Notes, the Indenture, the Notes, the Note Guarantees or the Security Documents may be amended or supplemented (subject, in the case of the Security Documents, to any further requirements in the Collateral Trust Agreement): (i) to cure any ambiguity, defect or inconsistency; (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes; (iii) to provide for the assumption of an Issuer’s or a Guarantor’s obligations to Holders of Notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of such Issuer’s or Guarantor’s properties or assets, as applicable; (iv) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under the Indenture of any Holder; (v) to conform the text of the Indenture, the Notes, the relevant Security Documents or the Note Guarantees to any provision of the “Description of the New Second Lien Notes” section of the Issuers’ Offering Memorandum dated April 17, 2020, to the extent that such provision in that “Description of the New Second Lien Notes” was intended to be a verbatim recitation of a provision of the Indenture, the Notes, the relevant Security Documents or the Note Guarantees; (vi) to provide for the issuance of Additional Notes and related Note Guarantees (and the grant of security for the benefit of

A-8

the Additional Notes and related Note Guarantees) or PIK Notes or to increase the outstanding principal amount of the Notes, in each case in accordance with the limitations set forth in the Indenture; (vii) to add any additional Guarantor or to evidence the release of any Guarantor from its Note Guarantee, in each case as provided in the Indenture; (viii) to evidence or provide for the acceptance of appointment under the Indenture of a successor Trustee or evidence and provide for a successor or replacement Collateral Trustee under the Security Documents; (ix) to make, complete or confirm any grant of Collateral permitted or required by the Indenture or any of the Security Documents or any release of Collateral or discharge or termination of any Lien on Collateral that becomes effective as set forth in the Indenture or any of the Security Documents; (x) to add additional secured parties to the extent Liens securing obligations held by such parties are permitted under the Indenture or any of the Security Documents; (xi) 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 Issuers’ 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 Trustee in accordance with the terms of this Indenture or otherwise; (xii) 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; (xiii) with respect to the Security Documents, as provided in the Collateral Trust Agreement; (xiv) to make any change not adverse to the Holders of the Notes in order to facilitate entry into the ABL Documents, Priority Lien Documents or other Junior Lien Documents; (xv) in the event that any PIK Notes are issued as Definitive Notes, to make appropriate amendments to reflect an appropriate minimum denomination of certificated PIK Notes and establish minimum redemption amounts for certificated PIK Notes; and (xvi) in the event of an issuance of MFN Debt, to increase the interest rate or provide for earlier final maturity or required payments of principal pursuant to Section 4.09(d) of the Indenture.

(12)DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest on the Notes; (ii) default in the payment when due of the principal of, or premium, if any, on, the Notes; (iii) failure by the Company to comply with its obligations under Section 5.01 of the Indenture or to consummate a purchase of Notes when required pursuant to Sections 4.10 or 4.14 of the Indenture; (iv) failure by the Company or any of its Restricted Subsidiaries for 30 days after written notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes to comply with the provisions of Section 4.07 or Section 4.09 of the Indenture or to comply with the provisions of Section 4.10 or Section 4.14 of the Indenture to the extent not described in the immediately preceding clause (iii); (v) (a) except as addressed in subclause (b) of this clause (v), failure by the Company or any of its Restricted Subsidiaries for 60 days after written notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes to comply with any of the other agreements in the Indenture or this Note or (b) failure by the Company for 180 days after notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then

A-9

outstanding Notes to comply with Section 4.03 of the Indenture; (vi) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, if that default: (a) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or (b) results in the acceleration of such Indebtedness prior to its Stated Maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $25.0 million or more; provided, however, that if, prior to any acceleration of the Notes, (1) any such Payment Default is cured or waived, (2) any such acceleration of such Indebtedness is rescinded, or (3) such Indebtedness is repaid within a period of 10 Business Days from the continuation of such default beyond any applicable grace period for such Payment Default or the occurrence of such acceleration, as the case may be, then any Default or Event of Default (but not any acceleration of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; (vii) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company), would constitute a Significant Subsidiary to pay final judgments (entered by a court or courts of competent jurisdiction) aggregating in excess of $25.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 days; (viii) except as permitted by the Indenture, any Note Guarantee is 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 Guarantor, denies or disaffirms its obligations under its Note Guarantee, except, in each case, by reason of the release of such Note Guarantee in accordance with the Indenture; (ix) an Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law (a) commences a voluntary case, (b) consents to the entry of an order for relief against it in an involuntary case, (c) consents to the appointment of a custodian of it or for all or substantially all of its property, (d) makes a general assignment for the benefit of its creditors, or (e) generally is not paying its debts as they become due; or (x) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (a) is for relief against any Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary in an involuntary case, (b) appoints a custodian of any Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of an Issuer or any of the Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or (c) orders the liquidation of an Issuer or any of the

A-10

Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, and the order or decree remains unstayed and in effect for 60 consecutive days; and (xi) 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 Junior 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 $25.0 million ceases to be an enforceable and perfected second-priority Lien, subject only to Permitted Liens; provided further, that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 30 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period; (b) except as permitted by this Indenture or the relevant Security Documents, any Junior 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 $25.0 million ceases to be an enforceable and perfected second-priority Lien in any material respect, subject to Permitted Liens, and such condition continues for 60 days after written notice by the Trustee or the Collateral Trustee (after the Trustee or Collateral Trustee has received written notice of such cessation from the holders of 25% or more of the aggregate principal amount of the Notes outstanding) 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 Trustee; provided further, that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 30 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period; 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. In the case of an Event of Default specified in the immediately preceding clause (ix) or clause (x), with respect to the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all then outstanding Notes will become due and payable immediately without further action or notice (subject to applicable law). If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately by notice in writing to the Company and, in the case of a notice by Holders, also to the Trustee specifying the respective Event of Default and that it is a notice of acceleration. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal of, or interest or premium, if any, on, any Note) if it in good faith determines that withholding notice is in their interest. The Holders of a majority in aggregate principal

A-11

amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration and its consequences if the rescission would not violate any judgment or decree and if all existing Events of Default (except non-payment of principal, interest or premium, if any, that has become due solely because of the acceleration) have been cured or waived. The Issuers are required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Issuers are required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

(13)TRUSTEE DEALINGS WITH THE ISSUERS. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for any Issuer or its Affiliates, and may otherwise deal with any Issuer or its Affiliates, as if it were not the Trustee.

(14)NO RECOURSE AGAINST OTHERS. None of the General Partner or any director, officer, partner, employee, incorporator, manager, unitholder or other owner of Capital Stock of the General Partner, the Issuers or any Guarantor, as such, will have any liability for any obligations of the Issuers or such Guarantor under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

(15)AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

(16)ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

(17)CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuers have caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. 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 and reliance may be placed only on the other identification numbers placed thereon.

SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of _________________, 20__, among _____________________ (the “Guaranteeing Subsidiary”), a subsidiary (or a permitted successor thereof) of CSI Compressco LP (“Compressco”), a Delaware limited partnership, or CSI Compressco Finance Inc. (“Finance Corp.,” and, together with Compressco, the “Issuers”), a Delaware corporation, the Issuers, the other Guarantors (as defined in the Indenture referred to herein), U.S. Bank National Association, as trustee (the “Trustee”), and U.S. Bank National Association, as collateral trustee under the Indenture referred to below (the “Collateral Trustee”).

W I T N E S S E T H

WHEREAS, the Issuers have heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of June 12, 2020 providing for the issuance of 10.000%/10.750% Senior Secured Second Lien Notes due 2026 (the “Notes”);

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’ Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee and the Collateral Trustee are authorized to execute and deliver this Supplemental Indenture.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of Notes as follows:

1.CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

2.AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 10 thereof.

3.EXECUTION AND DELIVERY. Each Guaranteeing Subsidiary agrees that the Note Guarantees shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.
