Section 2.07 Replacement Notes .

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

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

Section 2.08 Outstanding Notes .

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

39

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

Section 2.09 Treasury Notes .

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

Section 2.10 Temporary Notes .

Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

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

Section 2.11 Cancellation .

The Company at any time may deliver Notes to the Trustee for cancellation.

The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes shall be delivered to the Company upon written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

The Company shall 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 overdue interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail 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.

All references to “interest” in this Indenture and the Notes mean the initial interest rate borne by the Notes and, to the extent permitted by applicable law, any increases in that rate to the extent overdue interest accrues on the Notes.

The Holder of a Note may be treated as its owner for all purposes. Only Holders have rights under this Indenture and the Notes.

Section 2.14 Interest Payment Date; Record Date .

PIK Interest shall accrue at a rate of 11.000% and shall accrue from the date of original issuance of the Notes or, if interest has already been paid, from the date it was most recently paid. Any PIK Notes issued as PIK Interest shall be fungible with, and shall accrue interest at the same rate as, the Initial Notes.

(b) In the event that the Company elects to pay PIK Interest, no later than two Business Days prior to the relevant Interest Payment Date, the Company shall deliver notice of such election to the Trustee and the Paying Agent (if other than the Trustee). In the absence of such election notice, interest shall be payable in cash. Beginning with the October 15, 2017 Interest Payment Date, all interest payments shall be payable in cash. PIK Interest shall be payable (i) with respect to Notes represented by one or more Global Notes by increasing the principal amount of such outstanding Global Note by an amount equal to the amount of accrued interest (rounded up to the nearest whole dollar) (or, if necessary, pursuant to the requirements of the Depositary or otherwise, by authenticating new Global Notes with such increased principal amounts) and (ii) with respect to Notes represented by Definitive Notes, by issuing the required amount of new PIK Notes represented by certificated PIK Notes (rounded up to the nearest whole dollar) in an aggregate principal amount equal to the amount of accrued interest (rounded up to the nearest whole dollar), and the Trustee shall, at the request of the Company, 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.

41

(c) Payment shall be made in such form and terms as specified in this Section 2.15 and the Company shall, and the Paying Agent may, take additional steps as is necessary to effect such payment.

On or before the applicable Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis as provided in this Section 3.09 and in Section 4.20 hereof, to the extent necessary, the Offer Amount of Notes or portions thereof duly tendered and not duly withdrawn and any applicable pari passu Indebtedness, in each case, pursuant to the applicable Asset Sale Offer or if less than the Offer Amount has been tendered, all Notes duly tendered and not duly withdrawn and all applicable pari passu Indebtedness and shall deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than five days after the Purchase Date) mail to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase (or, in the case of any Notes that are in global form, make such payment through the facilities of DTC or any other applicable Depositary), and the Trustee, upon written request from the Company, shall promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new Note, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company (or, in the case of Global Notes, transferred by book entry) to the Holder thereof. The Company shall publicly announce the results of the applicable Asset Sale Offer on the Purchase Date.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.05 and 3.06 hereof. For purposes of clarity, the parties hereto agree that, anything in this Indenture or the Notes to the contrary notwithstanding, interest on any Note or portion thereof accepted for repurchase by the Company pursuant to Section 3.09, 4.19 or 4.20 shall cease to accrue on and after the applicable Purchase Date unless the Company defaults in making the payment due on such Note or portion thereof, as applicable, as provided herein.

54

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

(10) the Guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of Section 4.08; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Note Guarantee shall be subordinated or pari passu , as applicable, to other Indebtedness of the Guarantor to the same extent as the Indebtedness guaranteed;

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, insurance contracts, self-insurance obligations, bankers’ acceptances, performance and surety bonds and other similar guarantees of obligations not constituting Indebtedness in the ordinary course of business;

(12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days following receipt by the Company or such Restricted Subsidiary of notice or such event;

(13) any obligation arising from agreements of the Company or any Restricted Subsidiary of the Company providing for indemnification, adjustment of purchase price, earn outs, or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business, assets or Capital Stock of a Restricted Subsidiary (including, without limitation, assets acquired by a Restricted Subsidiary of the Company and any Person that, as a result of such transaction, becomes a Restricted Subsidiary of the Company) in a transaction permitted by this Indenture, provided the maximum liability in respect of all such Indebtedness incurred in connection with a disposition shall at no time exceed the gross proceeds including noncash proceeds (the Fair Market Value of such noncash proceeds being measured at the time received and without giving effect to any subsequent changes in value) actually received by the Company and its Restricted Subsidiaries in connection with such disposition;

55

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

For purposes of determining compliance with this Section 4.08, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) appearing above in this Section 4.08(b), or is entitled to be incurred pursuant to Section 4.08(a), the Company shall be permitted to classify and divide such item of Indebtedness on the date of its incurrence, and later reclassify and redivide all or a portion of such item of Indebtedness among any one or more of such clauses and/or Section 4.08(a), in any manner that complies with this Section 4.08. Indebtedness under Credit Facilities outstanding on the date of this Indenture shall initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest or dividends on Disqualified 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, the reclassification of Disqualified Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock shall not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.08; provided , in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges (to the extent required by the definition of such term) of the Company as accrued. 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. Notwithstanding any other provision of this Section, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. In determining the amount of Indebtedness outstanding, the outstanding amount of any particular Indebtedness of any Person shall be counted only once and any obligation of such person or any other Person under any guarantee, Lien, letter of credit or similar instrument supporting such Indebtedness shall be disregarded so long as it is permitted to be incurred by the Person or Persons incurring such obligation.

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

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

(2) with respect to contingent obligations, the maximum liability upon the occurrences of the contingency giving rise to the obligation;

(3) with respect to Hedging Obligations, the net amount payable, if any, by the specified Persons if such Hedging Obligations terminated at that time due to default by such Person;

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

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

56

(B) the amount of such Indebtedness of the other Person;

(5) the maximum amount the Company and its Restricted Subsidiaries would become obligated to pay upon the maturity of, or pursuant to any mandatory redemption provisions of, such Disqualified Stock, in the case of any Disqualified Stock;

(6) the amount of the liability in respect thereof determined in accordance with GAAP, in the case of Indebtedness issued at a price that is less than the principal amount thereof; and

(7) the principal amount of the Indebtedness, in the case of any other Indebtedness.

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.

Section 6.08 Collection Suit by Trustee or Noteholder Collateral Agent .

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 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee or the Noteholder Collateral Agent, as the case may be, to vote in respect of the claim of any Holder in any such proceeding.

First : to the Trustee, the Noteholder Collateral Agent, the Paying Agent and the Registrar for amounts due under Section 7.07 hereof, including payment of all reasonable compensation and expenses incurred, and all reasonable disbursements and advances made, by the Trustee or the Noteholder Collateral Agent, as the case may be, and the costs and expenses of collection;

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

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

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

Section 6.11 Undertaking for Costs .

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee or the Noteholder Collateral Agent, as the case may be, for any action taken or omitted by it as a Trustee or the Noteholder Collateral Agent, 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 or the Noteholder Collateral Agent, as the case may be, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

Section 6.12 Applicable Premium .

(1) In the event that (i) the Company’s obligations under this Indenture cease to be of effect as a result of satisfaction or discharge pursuant to Article 10 of this Indenture or (ii) any acceleration of the Notes occurs (and is not rescinded) or the Notes otherwise become due and payable prior to their Maturity Date as a result of an Event of Default (including, without limitation, an Event of Default specified in clause (10) or (11) of Section 6.01) (any such event, an “Applicable Premium Event,” and the date of any such Applicable Premium Event, an “Applicable Premium Date”), a payment in an amount equal to the Applicable Premium shall be immediately due and payable (subject to rescission, in the event that the underlying acceleration is rescinded), unless waived by the Holders of a majority of then-outstanding principal amount of the Notes, on the principal amount so accelerated or that has become or is declared to be immediately due and payable, and such Applicable Premium shall constitute part of the obligations in respect of such acceleration or other declaration. The Applicable Premium shall be payable along with the principal of, and any accrued and unpaid interest on, the Notes payable as a result of such Applicable Premium Event.

73

(2) The Applicable Premium provided for in Section 6.12(1) shall be paid in view of the impracticality and extreme difficulty of ascertaining actual damages and by mutual agreement of the Company and the Holders of the Notes as to a reasonable calculation of each Holder’s lost profits as a result thereof. Any Applicable Premium payable shall be presumed to be the liquidated damages sustained by each Holder as the result of an Applicable Premium Event, and the Company agrees that it is reasonable under the circumstances currently existing.

(3) The Company expressly waives (to the fullest extent it may lawfully do so) the provisions of any present or future statute or law that prohibits or may prohibit the collection of the Applicable Premium in connection with any such acceleration or declaration.

(4) The Company expressly agrees (to the fullest extent it may lawfully do so) that: (A) the Applicable Premium is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the Applicable Premium shall be payable notwithstanding the then prevailing market rates at the time payment is made; (C) there has been a course of conduct between Holders and the Company giving specific consideration in connection with the issuance of the Notes for such agreement to pay the Applicable Premium; and (D) the Company shall be estopped following the issuance of the Notes from claiming differently than as agreed to in this Section 6.12(3) and Section 6.12(4). The Company expressly acknowledges that its agreement to pay the Applicable Premium to Holders, if required by this Section 6.12, is a material inducement to Holders’ purchase of the Notes. The Applicable Premium shall constitute part of the Holders’ claim in respect of the Notes in the event of a bankruptcy or liquidation, and such claim shall be allowed against the debtors without the need to file a proof of claim.

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

(d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

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

Section 7.03 Individual Rights of Trustee .

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee.

(For purposes of clarity, the parties hereto agree that no “conflicting interest” shall arise under TIA Section 310(b) because the Trustee is trustee under another Indenture under which the Company or any Guarantor is an obligor.)

Section 7.06 [Reserved] .

Section 7.07 Compensation and Indemnity .

The Trustee’s compensation shall not be limited by any law on compensation of a Trustee of an express trust. The Company shall reimburse each Indemnified Party promptly upon request for all reasonable disbursements, advances and expenses incurred or made by such Indemnified Party in addition to the compensation for its services.

Each Indemnified Party shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Indemnified Party to so notify the Company shall not relieve the Company or any of the Guarantors of their Obligations hereunder or under the Security Documents. The Company or such Guarantor shall defend the claim and the applicable Indemnified Party shall cooperate in the defense. Each Indemnified Party may have separate legal counsel and the Company shall pay the reasonable fees and disbursements of such legal counsel; provided that, anything herein to the contrary notwithstanding, neither the Company nor any Guarantor shall be required to pay the fees and expenses of more than one firm of legal counsel for all of the Indemnified Parties in connection with any proceeding or related proceedings, which legal counsel shall be selected by the Trustee. Neither the Company nor any Guarantor need pay for any settlement made without the Company’s consent, which consent shall not be unreasonably withheld.

(d) To secure the Company’s and the Guarantors’ payment Obligations in this Section 7.07, the Trustee and the Noteholder Collateral Agent shall have a Lien prior to the Notes on all money, Collateral or property held or collected by the Trustee, in its capacity as Trustee, or the Noteholder Collateral Agent in its capacity as Noteholder Collateral Agent, except, in the case of the Trustee, such funds that are held in trust to pay principal, premium, if any, interest, if any, on particular Notes pursuant to Article 8 or 10 hereof. Such Lien shall survive the satisfaction and discharge of this Indenture.

(e) When an Indemnified Party incurs expenses or renders services after an Event of Default specified in Section 6.01(10) or (11) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Code.

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

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

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

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

(2) either (A) (i) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger (the “ Successor Guarantor ”), if other than such Guarantor, unconditionally assumes all the obligations of such Guarantor under its Note Guarantee, this Indenture and the Security Documents pursuant to a supplemental indenture to this Indenture and appropriate amendments to the Security Documents; (ii) the Successor Guarantor causes such amendments, supplements or other instruments to be

Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee (it being understood and agreed that such successor Person need not execute a notation of its Guarantee on Notes issued prior to the time that it became a Guarantor). All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

90

(2) in connection with any sale or other disposition of all of the Capital Stock of such Guarantor owned by the Company or any of its Restricted Subsidiaries to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.20 hereof and the Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition;
