Section 2.01    Form and Dating. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or depository procedure or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The Securities will be governed by this Indenture and by the provisions relating to the Securities set forth in Appendix A hereto, which is hereby incorporated into and expressly made a part of this Indenture. The terms of the Securities set forth in Exhibit A are part of the terms of this Indenture.

Section 2.02    Execution and Authentication. Two Officers shall sign the Securities for the Company by manual signature.

If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The manual signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

On the Issue Date, upon receipt of a written order of the Company signed by two Officers of the Company (a “Company Order”), the Trustee shall authenticate and deliver $381,568,000 of 9¼% Senior Secured Second Lien Notes due 2022 and, at any time and from time to time thereafter, the Trustee shall, upon receipt of a Company Order, authenticate and deliver Securities for original issue in an aggregate principal amount specified in such Company Order; provided that, in each case, the Trustee shall be

entitled to receive an Officers’ Certificate and an Opinion of Counsel of the Company that it may reasonably request in connection with such authentication of Securities. Such Company Order shall specify the amount of Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of an issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that such issuance is in compliance with this Indenture, including Sections 4.03 and 4.10 hereof.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

Section 2.03    Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration or transfer or for exchange, which office shall maintain the names and addresses of Securityholders (the “Registrar”), and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly-Owned Subsidiary incorporated or organized within the United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Securities.

Section 2.04    Paying Agent To Hold Money in Trust. Prior to 11:00 a.m., New York City time, on each due date of the principal and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders, the Trustee and the Collateral Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify in writing the Trustee of any default by the Company in making any such payment. If the Company or a Wholly-Owned Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee. Upon any Event of Default specified in Section 6.01(7) or (8), the Trustee shall automatically serve as the Paying Agent for the Securities.

Section 2.05    Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in

writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders.

Section 2.06    Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer and in compliance with Appendix A. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met.

When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Company’s request. The Company may require the Securityholders to make a payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section. The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of any Securities (i) selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) (ii) for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed or (iii) between a regular record date and the next succeeding interest payment date.

Prior to the due presentation for registration of transfer of any Security, the Company, the Subsidiary Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, any Subsidiary Guarantor, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

Any Holder of a beneficial interest in a Global Security shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by (a) the Holder of such Global Security (or its agent) or (b) any Holder of a beneficial interest in such Global Security, and that ownership of a beneficial interest in such Global Security shall be required to be reflected in a book entry.

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

Section 2.07    Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee, upon the Company’s written instruction, shall authenticate and deliver a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar and in the judgment of the Trustee to protect the Trustee, the Paying Agent, the Registrar and any of the Trustee’s agents from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security.

Every replacement Security is an additional obligation of the Company.

Section 2.08    Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and the Paying Agent is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

Section 2.09    Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate and deliver temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as definitive Securities.

Section 2.10    Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment or cancellation. The Trustee and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and, following the Company’s written request, shall deliver a certificate of such destruction to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation.

Section 2.11    Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the Persons who are Securityholders on a subsequent special record date as provided in the Securities and in Section 4.01 hereof. The Company shall fix or cause to be fixed any such special record date and payment date and shall promptly send to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

Section 2.12    CUSIP Numbers and ISINs. The Company in issuing the Securities may use “CUSIP” numbers and/or “ISINs” (if then generally in use) and, if so, the Trustee shall use CUSIP numbers and/or ISINs in notices as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such notice shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP number or ISINs applicable to the Securities.

Section 2.13    Issuance of Additional Securities. The Company shall be entitled, subject to its compliance with Sections 4.03 and 4.10, to issue Additional Securities under this Indenture which shall have identical terms as the Securities issued on the Issue Date, other than with respect to the date of issuance and issue price; provided that such Additional Securities are fungible with the Securities for U.S. federal income tax purposes or are issued under a separate CUSIP number and ISIN. The Securities issued on the Issue Date and any Additional Securities shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

(1)the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture; and

(2)the issue price, the issue date and the CUSIP number and ISIN of such Additional Securities.

Section 2.14    Designation of Securities. The Securities and the Subsidiary Guarantees shall constitute “Senior Indebtedness,” and the Company and the Subsidiary Guarantors hereby designate the Securities and the Subsidiary Guarantees as “Designated Senior Indebtedness” of the Company and the Subsidiary Guarantors, for purposes of the Existing Subordinated Notes Indentures. The Securities and the Subsidiary Guarantees shall be superior in right of payment to the Existing Subordinated Notes and the Guarantees thereof.

Section 3.01    Notices to Trustee. If the Company elects to redeem Securities pursuant to paragraph 5 of the Securities, it shall notify the Trustee in writing of the redemption date, the principal amount of Securities to be redeemed and the paragraph of the Securities pursuant to which the redemption shall occur.

The Company shall give each notice to the Trustee provided for in this Section at least 45 days before the redemption date unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect that such redemption shall comply with the conditions herein.

Section 3.02    Selection of Securities To Be Redeemed. If fewer than all the Securities are to be redeemed, the Securities will be redeemed on a pro rata basis (or for Securities held in book-entry form, in accordance with the applicable procedures of DTC). The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them the Trustee selects shall be in amounts of $2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company, the Registrar and each Paying Agent promptly of the Securities or portions of Securities to be redeemed.

Section 3.03    Notice of Redemption. At least 30 days but not more than 60 days before a date for redemption of Securities, the Company shall send a notice of redemption by electronic transmission or by first-class mail to each Holder of Securities to be redeemed.

The notice shall identify the Securities to be redeemed and shall state:

(1)the redemption date;

(2)the redemption price;

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

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

(5)if fewer than all the outstanding Securities are to be redeemed, the identification and principal amounts of the particular Securities to be redeemed;

(6)that, unless the Company defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Securities (or portions thereof) called for redemption ceases to accrue on and after the redemption date;

(7)the CUSIP number or ISIN, if any, printed on the Securities being re-deemed; and

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

At the Company’s request made at least five (5) Business Days prior to the date on which a notice of redemption is to be sent (or such shorter period as may be agreed by the Trustee), the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section.

Section 3.04    Effect of Notice of Redemption. Once notice of redemption is sent, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, subject to any condition or contingency stated therein. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest to but not including the redemption date. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

Section 3.05    Deposit of Redemption Price. Prior to 11:00 A.M. New York time on the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued and unpaid interest on all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Trustee for cancellation.

Section 3.06    Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

Section 4.01    Payment of Securities. The Company shall promptly pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities and in this Indenture. Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture.

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

Section 4.02    Reports and Other Information.

Section 4.03    Limitation on Indebtedness.

(a)The Company shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided, however, that the Company or a Restricted Subsidiary may Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto, the Consolidated Coverage Ratio equals or exceeds 2.25 to 1.0.

(3)    (A) the Securities, any Additional Securities, any other Parity Lien Debt, any Junior Lien Debt and any unsecured Indebtedness in an aggregate principal amount outstanding, together with all other Indebtedness outstanding under this clause (b)(3)(A), not to exceed the greater of (x) $1,000.0 million and (y) (I) 65.0% of Modified ACNTA determined as of the date of such Incurrence minus (II) the aggregate amount of all Indebtedness outstanding under Credit Facilities Incurred under Section 4.03(b)(1) as of the date of such Incurrence (assuming for such purposes that all available amounts under Section 4.03(b)(1) are fully drawn); provided, however, that any Parity Lien Debt, Junior Lien Debt or unsecured Indebtedness Incurred under this clause (b)(3)(A) after the Issue Date shall not have a Stated Maturity any earlier than the Stated Maturity of the Securities, and (B) [Reserved];

Section 4.07    Limitation on Sales of Assets and Subsidiary Stock.

(a)The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless (1) the Company or such Restricted Subsidiary receives consideration at least equal to the fair market value (such fair market value to be determined in advance in good faith by an Officer or an officer of such Restricted Subsidiary with responsibility for such transaction, or if the Asset Disposition exceeds $50.0 million, by the Board of Directors, which determination shall be conclusive evidence of compliance with this provision), of the equity and assets subject to such Asset Disposition; (2) (A) at least 75% of the consideration received by the Company or

such Restricted Subsidiary is in the form of cash or cash equivalents, Additional Assets or any combination thereof (collectively, the “Cash Consideration”) or (B) the fair market value of all forms of consideration other than Cash Consideration received by the Company and its Restricted Subsidiaries since September 30, 2017 does not exceed in the aggregate 10% of ACNTA at the time of the applicable Asset Disposition (after giving effect to such Asset Disposition); and (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company (or such Restricted Subsidiary, as the case may be) (A) first, (i) if the assets subject to such Asset Disposition constitute Collateral, to the extent the Company elects (or is required by the terms of any Indebtedness), to prepay, repay, redeem or purchase Priority Lien Debt and other outstanding Priority Lien Obligations or Parity Lien Debt and other outstanding Parity Lien Obligations (in each case, other than Indebtedness owed to the Company or an Affiliate of the Company) within 540 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, provided such prepayment, repayment, redemption or purchase permanently retires, or reduces the related loan commitment (if any) for, such Indebtedness in an amount equal to the principal amount so prepaid, repaid, redeemed or purchased (and, with respect to Parity Lien Debt, such prepayment, repayment, redemption or purchase must be made either (x) for Securities only or (y) for Securities and other Parity Lien Debt, and in the case of subclause (y), by a pro rata prepayment, repayment or redemption of outstanding Securities and such other Parity Lien Debt or by an offer to purchase on a pro rata basis made to all holders of Securities and such other Parity Lien Debt) or (ii) if the assets subject to such Asset Disposition do not constitute Collateral, to the extent the Company elects (or is required by the terms of any Indebtedness), to prepay, repay, redeem or purchase Senior Indebtedness of the Company or any Subsidiary Guarantor in each case that is Secured Debt or Indebtedness (other than Disqualified Stock) of a Wholly-Owned Subsidiary that is not a Subsidiary Guarantor (other than Indebtedness owed to the Company or an Affiliate of the Company) within 540 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, provided such prepayment, repayment, redemption or purchase permanently retires, or reduces the related loan commitment (if any) for, such Indebtedness in an amount equal to the principal amount so prepaid, repaid, redeemed or purchased; (B) second, to the extent of the balance of such Net Available Cash after application in accordance with clause (A), to the extent the Company elects, to acquire Additional Assets or to make capital expenditures in the Oil and Gas Business within 540 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; provided that, without limitation of the provisions of Section 10.03, any such Additional Assets, including the assets of any Person that becomes a Subsidiary Guarantor as a result of such transaction, acquired with Net Available Cash from an Asset Disposition of Collateral are, to the extent required by the Priority Lien Documents or the Security Documents (and pursuant to the terms thereof), pledged as Collateral; and (C) third, to the extent of the balance of such Net Available Cash after application in accordance with clauses (A) and (B), to make an offer to the Holders (and to holders of other Parity Lien Debt of the Company designated by the Company) to purchase Securities (and such other Parity Lien Debt of the Company) pursuant to and subject to the conditions contained in this Indenture, which purchase permanently reduces the outstanding amount of such Securities (and such other Parity Lien Debt) in an amount equal to (or greater than) the principal amount purchased.

Pending application of Net Available Cash pursuant to this Section 4.07(a), such Net Available Cash shall be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit Indebtedness (which may include Priority Lien Debt).

(b)Notwithstanding Section 4.07(a), the Company and the Restricted Subsidiaries shall not be required to apply any Net Available Cash in accordance with Section 4.07(a) except to the extent that the aggregate Net Available Cash from all Asset Dispositions, which is not applied in accordance with Section 4.07(a), exceeds $40.0 million during any calendar year.

For the purposes of Section 4.07(a), the following are deemed to be cash or cash equivalents (i) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Securities or any Subsidiary Guarantee) that are assumed by the transferee of any such Asset Disposition pursuant to (A) a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability or (B) an assignment agreement that includes, in lieu of such a release, the agreement of the transferee or its parent company to indemnify and hold harmless the Company or such Restricted Subsidiary from and against any loss, liability or cost in respect of such assumed liability and (ii) any non-Cash Consideration received by the Company or any Restricted Subsidiary from the transferee that is converted, monetized, sold or exchanged by the Company or such Restricted Subsidiary into cash or cash equivalents within 120 days of receipt. Notwithstanding the foregoing, the 75% limitation referred to in Section 4.07(a)(2) shall be deemed satisfied with respect to any Asset Disposition in which the cash or cash equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Disposition complied with the aforementioned 75% limitation. The requirement of Section 4.07(a)(3)(B) shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to therein is entered into by the Company or its Restricted Subsidiary within the time period specified in such clause and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

(c)In the event of an Asset Disposition that requires the purchase of Securities (and other Parity Lien Debt of the Company) pursuant to Section 4.07(a)(3)(C), the Company shall make such offer to purchase Securities on or before the 541st day after the later of the date of such Asset Disposition or the receipt of such Net Available Cash, and shall purchase Securities tendered pursuant to an offer by the Company for the Securities (and if required or permitted by the terms of any other Parity Lien Debt, to the holders of such Indebtedness) at a purchase price of 100% of their principal amount (or, in the event (x) such other Parity Lien Debt (other than the Existing Second Lien Notes) of the Company was issued with original issue discount greater than 2.5% and (y) the Existing Second Lien Notes are outstanding, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest (or, in respect of such other Parity Lien Debt of the Company, such lesser price, if any, as may be provided for by the terms of such Parity Lien Debt of the Company) in accordance with the procedures (including prorating in the event of oversubscription) set forth in Section 3.02; provided, however, that if the terms of an asset sale covenant relating to the Secured Debt outstanding as of the Issue Date would require that such Secured Debt be included in an offer hereunder for the Securities, and the terms of such Secured Debt require that the price offered to the Securities in such offer be at a price not greater than 100% of accreted value, the Company may make the offer for the Securities hereunder at a price of 100% of accreted value so long as the Company has previously made an offer with the then remaining Net Available Cash from the applicable Asset Disposition for the Securities under Section 4.07(a)(3)(A) or otherwise at a price of 100% of principal amount. If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their purchase, the Company shall select the securities to be purchased on a pro rata basis but in round denominations, which in the case of the Securities shall be minimum denominations of $2,000 principal amount and whole multiples of $1,000 in excess thereof. The Company shall not be required to make such an offer to purchase Securities (and other Parity Lien Debt of the Company) pursuant to this Section 4.07 if the Net Available Cash not applied or invested as provided in Section 4.07(a)(3)(A) or (B) is less than $20.0 million (which lesser amount shall be carried forward for purposes of determining whether such an offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an offer to purchase, Net Available Cash shall be deemed to be reduced by the aggregate amount of such offer.

(d)The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to Section 4.07(c). To the extent that the provisions of any securities laws or regulations conflict with provisions of Section 4.07(c), the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under Section 4.07(c) by virtue of its compliance with such securities laws or regulations.

Section 4.08    Limitation on Affiliate Transactions.

(a)The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with any Affiliate of the Company (an “Affiliate Transaction”) unless the terms thereof (1) are no less favorable to the Company or such Restricted Subsidiary than those that could be obtained at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate, (2) if such Affiliate Transaction involves an amount in excess of $15.0 million, are set forth in writing and have been approved by the Board of Directors, including a majority of the members of the Board of Directors having no personal stake in such Affiliate Transaction, and (3) if such Affiliate Transaction involves an amount in excess of $25.0 million, have been determined by a nationally recognized investment banking or accounting firm or other qualified independent appraiser to be fair, from a financial standpoint, to the Company and its Restricted Subsidiaries.

(b)The provisions of Section 4.08(a) shall not prohibit (i) any sale of hydrocarbons or other mineral products to an Affiliate of the Company or the entering into or performance of Oil and Gas Hedging Contracts, gas gathering, transportation or processing contracts or oil or natural gas marketing or exchange contracts with an Affiliate of the Company, in each case, in the ordinary course of business, so long as the terms of any such transaction are approved by a majority of the members of the Board of Directors who are disinterested with respect to such transaction, (ii) the sale to an Affiliate of the Company of Capital Stock of the Company that does not constitute Disqualified Stock, and the sale to an Affiliate of the Company of Indebtedness (including Disqualified Stock) of the Company in connection with an offering of such Indebtedness in a market transaction and on terms substantially identical to those of other purchasers in such market transaction, (iii) transactions contemplated by any employment agreement or other compensation plan or arrangement existing on the Issue Date or thereafter entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business, (iv) the payment of reasonable fees to directors of the Company and its Restricted Subsidiaries who are not employees of the Company or any Restricted Subsidiary, (v) transactions between or among the Company and its Restricted Subsidiaries, (vi) transactions between the Company or any of its Restricted Subsidiaries and Persons that are controlled (as defined in the definition of “Affiliate”) by the Company (an “Unrestricted Affiliate”); provided that no other Person that controls (as so defined) or is under common control with the Company holds any Investments in such Unrestricted Affiliate; (vii) Restricted Payments that are permitted by the provisions of Section 4.05; and (viii) loans or advances to employees in the ordinary course of business and approved by the Company’s Board of Directors in an aggregate principal amount not to exceed $2.5 million outstanding at any one time.

(a)Upon the occurrence of a Change of Control, each Holder shall have the right to require that the Company purchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment

The Company shall cause each domestic Restricted Subsidiary that represents 10% or more of the book assets of, or 10% or more of the ACNTA of, the Company and its Restricted Subsidiaries, taken as a whole, or that Guarantees or otherwise has an aggregate of $15.0 million or more of Indebtedness or Preferred Stock outstanding at any time to promptly Guarantee the Securities pursuant to a Supplemental Indenture substantially in the form attached hereto as Exhibit 1 and execute and deliver all documents and take all other actions required to grant a security interest to the Collateral Trustee as required under Section 10.03.

Section 4.14    Suspension of Certain Covenants.

(a)If at any time after the Issue Date: (i) the Securities have Investment Grade Ratings from both Rating Agencies and (ii) no Event of Default has occurred and is continuing under this Indenture at such time (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), then until the end of the Suspension Period (as defined in Section 4.14(b)) the Company and the Restricted Subsidiaries shall not be subject to the provisions under Sections 4.03, 4.04, 4.05 (provided that no Restricted Subsidiary may be designated as an Unrestricted Subsidiary during the Suspension Period), 4.06, 4.07, 4.08, and paragraph (iii) of Section 5.01 (collectively, the “Suspended Covenants”).

(b)In the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to the Securities below an Investment Grade Rating, then the Company and the Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants with respect to future events. Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default shall be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the period of time between the Covenant Suspension Event and the Reversion Date (the “Suspension Period”), or upon termination of the Suspension Period or after that time based on any actions taken by the Company or its Restricted Subsidiaries during the Suspension Period. On the Reversion Date, all Indebtedness incurred during the Suspension Period shall be classified as having been incurred pursuant to Section 4.03(a) or Section 4.03(b) (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such

Indebtedness would not be so permitted to be incurred pursuant to Section 4.03(a) or Section 4.03(b), such Indebtedness shall be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.03(b)(4). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.05 shall be made as though Section 4.05 had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period shall reduce the amount available to be made as Restricted Payments under Section 4.05(a)(3) except to the extent that such Restricted Payments were permitted to have been made and are treated as having been made pursuant to Section 4.05(b).

(c)The Company shall promptly notify the Trustee in an Officers’ Certificate of the existence, and of the termination, of any Covenant Suspension Event or Reversion Date; provided, however, that the Trustee shall have no obligation to (i) monitor the ratings of the Securities, (ii) discover or verify the existence or termination of any Covenant Suspension Event or Reversion Date or (iii) notify holders of the Securities of any of the foregoing.

Section 5.01    When Company May Merge or Transfer Assets. The Company shall not consolidate with or merge with or into, or convey, transfer or lease, in one transaction or series of related transactions, all or substantially all the assets of the Company and its Restricted Subsidiaries, taken as a whole, to, any Person, unless:

(i)(A) the resulting, surviving or transferee Person (the “Successor Company”) shall be a Person organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and (B) the Successor Company (if not the Company) shall expressly assume, by an indenture supplemental hereto, and such other acknowledgments, joinder agreements or other documents as are required, all the obligations of the Company under the Note Documents;

(ii)immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Company or any Subsidiary as a result of such transaction as having been Incurred by such Successor Company or such Subsidiary at the time of such transaction), no Default shall have occurred and be continuing;

(iii)immediately after giving effect to such transaction, the Successor Company would be able to Incur an additional $1.00 of Indebtedness pursuant to Section 4.03(a);

(iv)immediately after giving effect to such transaction, the Successor Company shall have Adjusted Consolidated Net Tangible Assets that are not less than the Adjusted Consolidated Net Tangible Assets prior to such transaction;

(v)in the case of a conveyance, transfer or lease of all or substantially all the assets of the Company and its Restricted Subsidiaries, taken as a whole, such assets shall have been so conveyed, transferred or leased as an entirety or virtually as an entirety to one Person;

(vi)the Successor Company (if other than the Company) shall take such action (or agree to take such action) as may be reasonably necessary to cause any property or assets that constitute Collateral owned by or transferred to the Successor Company to be subject to the Parity Liens in the manner and to the extent required under the Note Documents; and

(vii)the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, transfer or lease and such supplemental indenture (if any) comply with this Indenture;

provided, however, that clauses (iii) and (iv) shall not be applicable to any such transaction solely between the Company and any Restricted Subsidiary.

The Successor Company shall be the successor to the Company and shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture and the other Note Documents, and the predecessor Company, except in the case of a lease, shall be released from the obligations thereunder.

Section 5.02    When Subsidiary Guarantors May Merge or Transfer Assets. The Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to any Person unless: (i) the resulting, surviving or transferee Person (if not such Subsidiary) shall be a Person organized and existing under the laws of the jurisdiction under which such Subsidiary was organized or under the laws of the United States of America, or any State thereof or the District of Columbia, and, if such Person is not the Company or a Subsidiary Guarantor, such Person shall expressly assume, by executing a Guarantee Agreement and such other acknowledgements, joinder agreements or other documents as are required, as applicable, all the obligations of such Subsidiary, if any, under the Note Documents; (ii) immediately after giving effect to such transaction or transactions on a pro forma basis (and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been issued by such Person at the time of such transaction), no Default shall have occurred and be continuing; (iii) in the case of a conveyance, transfer or lease of all or substantially all the assets of a Subsidiary Guarantor, such assets shall have been so conveyed, transferred or leased as an entirety or virtually as an entirety to one Person; (iv) the resulting, surviving or transferee Person (if other than the Subsidiary Guarantor) shall take such action (or agree to take such action) as may be reasonably necessary to cause any property or assets that constitute Collateral owned by or transferred to such Person to be subject to the Parity Liens in the manner and to the extent required under the Note Documents; and (v) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, transfer or lease and such Guarantee Agreement, if any, complies with this Indenture and such Guarantee Agreement, if any, is enforceable. The provisions of clauses (i), (ii) and (iv) above shall not apply to any one or more transactions which constitute an Asset Disposition if the Company has complied with Section 4.07. The resulting, surviving or transferee Person (if not such Subsidiary) shall be the successor to such Subsidiary Guarantor, and shall succeed to, be substituted for, and may exercise every right and power of, such Subsidiary Guarantor under this Indenture and the other Note Documents, and the predecessor Subsidiary Guarantor, except in the case of a lease, shall be released from the obligations thereunder.

Section 6.01    Events of Default. An “Event of Default” occurs if:

(1)the Company defaults in any payment of interest on any Security when the same becomes due and payable and such default continues for a period of 30 consecutive days;

(2)the Company (i) defaults in the payment of the principal of any Security when the same becomes due and payable at its Stated Maturity, upon optional redemption, upon

required purchase, upon declaration of acceleration or otherwise or (ii) fails to redeem or purchase Securities when required pursuant to this Indenture or the Securities;

(3)the Company fails to comply with Section 5.01;

(4)the Company fails to comply with Section 4.02, 4.03, 4.04, 4.05, 4.06, 4.07 (other than a failure to purchase Securities when required under Section 4.07), 4.08, 4.09 (other than a failure to purchase Securities when required under Section 4.09), 4.10, 4.11 or 4.13 and such failure continues for 30 consecutive days after the notice specified below;

(5)the Company or any Restricted Subsidiary fails to comply with any of its agreements contained in the Securities or in the Note Documents (other than those referred to in (1), (2), (3) or (4) above) and such failure continues for 60 consecutive days after the notice specified below;

(6)Indebtedness of the Company (other than Non-recourse Purchase Money Indebtedness) is not paid within any applicable grace period after final maturity or the maturity of such Indebtedness is accelerated by the holders thereof because of a default (and such acceleration is not rescinded or annulled) and the total amount of such Indebtedness unpaid or accelerated exceeds $75.0 million;

(7)the Company or any Significant Subsidiary pursuant to or within the meaning of any 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 any substantial part of its property; or

(D)    makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to insolvency;

(8)a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(A)    is for relief against the Company or any Significant Subsidiary in an involuntary case;

(B)    appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property; or

(C)    orders the winding up or liquidation of the Company or any Significant Subsidiary;

or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days;

(9)any judgment or decree for the payment of money in an uninsured or unindemnified amount in excess of $75.0 million or its foreign currency equivalent at the time is rendered against the Company or a Significant Subsidiary and is not discharged and either (A) an enforcement proceeding has been commenced by any creditor upon such judgment or decree or (B) there is a period of 60 days following the entry of such judgment or decree during which such judgment or decree is not discharged, waived, bonded or the execution thereof stayed, in either case 10 days after the notice specified below;

(10)any Subsidiary Guarantee ceases or otherwise fails to be in full force and effect (other than in accordance with the terms of such Subsidiary Guarantee) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee if such default continues for a period of 10 days after the notice specified below; or

(11)the occurrence of any of the following:

(A)    except as permitted by the Note Documents, any Security Document establishing the Parity Liens ceases for any reason to be enforceable; 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 is that any Parity 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 $35.0 million, ceases to be enforceable; provided further that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 60 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 the Note Documents, any Parity Lien purported to be granted under any Security Document on Collateral, individually or in the aggregate, having a fair market value of at least $35.0 million, ceases to be an enforceable and perfected second-priority Lien, subject only to Permitted Liens and the terms of the Intercreditor Agreement; provided that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 60 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; and

(C)    the Company or any Subsidiary Guarantor, or any Person acting on behalf of any of them, denies or disaffirms, in writing, any obligation of the Company or any Subsidiary Guarantor set forth in or arising under any Security Document establishing Parity Liens.

The foregoing shall constitute “Events of Default” whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

A Default under clause (4), (5), (9) or (10) is not an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the Securities notify the Company of the Default and the

Company does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice, in the form of an Officers’ Certificate, of any Event of Default under clause (3), (6) or (11) of this Section 6.01 and any event which with the giving of notice or the lapse of time would become an Event of Default under clause (4), (5), (9) or (10) of this Section 6.01, describing its status and what action the Company is taking or proposes to take with respect thereto. The Trustee shall not be deemed to have knowledge of any Default or Event of Default unless one of its Trust Officers receives written notice thereof from the Company or any of the Holders and such notice shall specify the Default and refer to this Indenture or the Securities.

Section 6.02    Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(7) or (8) with respect to the Company) occurs and is continuing, the Trustee by written notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by written notice to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(7) or (8) with respect to the Company occurs and is continuing, the principal of and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. Any such amount hereby constitutes liquidated damages reasonably agreed by the Company and the Holders in view of the impracticability of determining actual damages. The Holders of a majority in principal amount of the outstanding Securities by written notice to the Trustee and the Company may rescind any acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto. If the Securities are accelerated or otherwise become due prior to their Stated Maturity, in each case, as a result of an Event of Default, the amount of principal of, accrued and unpaid interest and premium on the Securities that becomes due and payable shall equal (a) 100% of the principal amount of the Securities redeemed, plus (b) a premium equal to the Applicable Premium in effect on the date of such acceleration, determined as if such acceleration were an optional redemption of the Securities accelerated and as if references to “March 31, 2019” in the definitions of “Applicable Premium” and “Treasury Rate” were instead references to “March 31, 2022” (such amount, the “Prepayment Premium”), plus (c) accrued and unpaid interest.

Without limiting the generality of the foregoing, it is understood and agreed that, if the Securities are accelerated or otherwise become due prior to their Stated Maturity, in each case, in respect of any Event of Default (including, but not limited to, upon the occurrence of a voluntary or involuntary bankruptcy or insolvency event (including the acceleration of claims by operation of law) or pursuant to a plan of reorganization, the Prepayment Premium will also be due and payable as though the Securities were optionally redeemed and shall constitute part of the Obligations under the Securities, in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the Company and the Holders as to a reasonable calculation of each Holder’s lost profits as a result thereof. Any premium payable above shall be presumed to be the liquidated damages sustained by each Holder as the result of the early redemption and the Company agrees that it is reasonable under the circumstances currently existing. The premium shall also be payable in the event the Securities (and/or this Indenture) are satisfied or released by foreclosure (whether or not by power of judicial proceeding), deed in lieu of foreclosure or by any other means. THE COMPANY EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE

STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. The Company expressly agrees (to the fullest extent it may lawfully do so) that: (A) the premium is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the premium shall be payable notwithstanding the then prevailing market rates at the time payment is made; (C) there has been a course of conduct between Holders and the Company giving specific consideration in this transaction for such agreement to pay the premium; and (D) the Company shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The Company expressly acknowledges that its agreement to pay the premium to Holders as herein described is a material inducement to Holders to purchase the Securities.

Section 6.03    Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.04    Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities by written notice to the Trustee may waive an existing or past Default and its consequences except (i) a Default in the payment of the principal of or interest on a Security or (ii) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

Section 6.05    Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law, this Indenture or the Intercreditor Agreement or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other Securityholder or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to be furnished with indemnification satisfactory to it in its sole discretion against all losses, liabilities and expenses caused by taking or not taking such action.

Section 6.06    Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

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

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

(3)such Holder or Holders furnish, if required by the Trustee, to the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

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

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

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

Section 6.07    Rights of Holders To Receive Payment. Notwithstanding any other provision of this Indenture, the contractual right of any Holder to receive payment of principal of, premium (if any) or interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, shall not be impaired or affected without the consent of such Holder, and the right of any Holder 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 6.08    Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company and the Subsidiary Guarantors for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

Section 6.09    Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Securityholders allowed in any judicial proceedings relative to the Company or any Subsidiary Guarantor their respective creditors or their respective property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07.

Section 6.10    Priorities. Subject to the Intercreditor Agreement and the Collateral Trust Agreement, if the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

FIRST: to the Trustee and the Collateral Trustee for amounts due under Section 7.07;

SECOND: to Securityholders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

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

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section. At least 15 days before such record date, the Company shall mail to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid.

Section 6.11    Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, 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 pursuant to Section 6.07 or a suit by Holders of more than an aggregate of 10% in principal amount of the outstanding Securities.

Section 6.12    Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

Section 7.01    Duties of Trustee.

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

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

(1)the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture 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 shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein).

(d)[Reserved].

(e)The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.

(f)Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g)No provision of this Indenture shall require the Trustee to advance, expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(h)Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01.

(i)Notwithstanding anything to the contrary herein, the Trustee shall have no duty to review the reports and information documents required to be provided by Section 4.02 for the purposes of determining compliance with any provisions of this Indenture.

Section 7.02    Rights of Trustee.

(a)The Trustee may rely on any document 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 shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

(f)In no event shall the Trustee be liable to any Person for punitive damages.

(g)The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder, including the Collateral Trustee.

(h)The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture or the other Note Documents at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the losses, liabilities and expenses which may be incurred therein or thereby.

(i)The Trustee may request that the Company delivers an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture or the other Note Documents.

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

(k)The permissive rights of the Trustee enumerated hereunder shall not be construed as duties.

Section 7.03    Individual Rights of Trustee. The Trustee in its individual or any other capacity (including in its capacity as the Collateral Trustee) may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

Section 7.04    Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture, the Note Documents or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

Section 7.05    Notice of Defaults. If a Default occurs and is continuing and (i) a Trust Officer has actual knowledge of such Default or (ii) written notice of such Default is given to the Trustee by the Company or Holders of at least 25% in aggregate principal amount of the Securities and such notice references the Securities and this Indenture, the Trustee shall mail or otherwise deliver in accordance with the applicable procedures of DTC to each Securityholder notice of the Default within the later of (i) 90 days after it occurs and (ii) 10 Business Days after such actual knowledge or written notice. Except in the case of a Default in payment of principal of or interest on any Security (including payments pursuant to the mandatory redemption provisions of such Security, if any), the Trustee may withhold the notice if and so long as the Trust Officer responsible for administering this Indenture and the Securities in good faith determines that withholding notice is not opposed to the interests of Securityholders.

Section 7.06    [Reserved].

Section 7.07    Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its services, including extraordinary services such as default administration. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee and its officers, directors, employees and agents against any and all loss, liability or expense (including attorneys’ fees) arising out of its acceptance of this trust or incurred by any of them in

connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture against the Company (including under this Section 7.07). The Trustee shall notify the Company promptly of any claim (whether asserted by any Securityholder or the Company) for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, gross negligence or bad faith as determined by a final, non-appealable judgment of a court of competent jurisdiction.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

The Company’s obligations pursuant to this Section and immunities of the Trustee contained in this Section shall survive the resignation or removal of the Trustee and the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or (8) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

Section 7.08    Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount outstanding of the Securities may remove the Trustee upon 30 days written notice to the Trustee and may appoint a successor Trustee. A Holder may petition a court of competent jurisdiction to remove the Trustee in the manner and under the circumstances contemplated by Section 310(b)(iii) of the TIA. The Company shall remove the Trustee if:

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

(2)the Trustee is adjudged bankrupt or insolvent;

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

(4)the Trustee otherwise becomes incapable of acting.

If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount outstanding of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount outstanding of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

Section 7.09    Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

Section 7.10    Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Section 310(a) of the TIA. The Trustee shall have a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition. The Trustee shall comply with Section 310(b) of the TIA, subject to its right to apply for a stay of its duty to resign under the penultimate paragraph of Section 310(b) of the TIA; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the TIA any series of securities issued under this Indenture and any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met.

This Indenture shall always have a Trustee who satisfies the requirements of Sections 310(a)(1), (2) and (5) of the TIA. The Trustee shall comply with Section 310(b) of the TIA.

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

Section 8.01    Discharge of Liability on Securities; Defeasance.

(a)When either (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities not theretofore delivered to the Trustee for cancellation: (1) have become due and payable, or (2) will become due and payable at their Stated Maturity within one year, or (3) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and, in the case of clause (ii), the Company irrevocably deposits with the Trustee money or U.S. Government Obligations sufficient (if payable other than solely

in money, in the opinion of a nationally recognized bank, appraisal firm or independent accounting firm), without consideration of any reinvestment of interest, to pay at maturity or upon redemption all outstanding Securities, including interest thereon to maturity or such redemption date (other than Securities replaced pursuant to Section 2.07), and if in the case of either clause (i) or (ii) the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 8.01(c), cease to be of further effect, each Subsidiary Guarantor will be released from all its obligations with respect to its Subsidiary Guarantee and any security granted to secure the Securities and Subsidiary Guarantees will be released. Upon satisfaction of the conditions set forth in this Section 8.01, the Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company.

(b)Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate (i) all its obligations under the Securities and this Indenture (“legal defeasance option”) or (ii) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11 and 4.13 and the operation of Sections 6.01(4), 6.01(6), 6.01(7) (but only with respect to Significant Subsidiaries), 6.01(8) (but only with respect to Significant Subsidiaries), 6.01(9), 6.01(10) and 6.01(11) and its obligations under Section 5.01(iii) and (iv) and under Section 5.02(iii) and (iv) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Section 6.01(4), 6.01(6), 6.01(7) (but only with respect to Significant Subsidiaries), 6.01(8) (but only with respect to Significant Subsidiaries), 6.01(9), 6.01(10) or 6.01(11) or because of the failure of the Company to comply with Section 5.01(iii) or (iv) or with Section 5.02(iii) or (iv). If the Company exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor shall be released from all its obligations with respect to its Subsidiary Guarantee and any security granted to secure the Securities and Subsidiary Guarantees will be released except to the extent necessary to guarantee any of the Company’s continuing obligations pursuant to Section 8.01(c) hereof.

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

(c)Notwithstanding Sections 8.01 (a) and (b), the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.07, 7.07, 7.08 and this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive.

Section 8.02    Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if:

(1)the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to maturity or redemption, as the case may be;

(2)the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing its opinion that the payments of principal of and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment shall provide cash at such times and in such amounts as shall be sufficient to pay principal and interest when due on all the Securities to maturity or redemption, as the case may be;

(3)123 days pass after the deposit is made and during the 123-day period no Default specified in Section 6.01(7) or (8) with respect to the Company occurs which is continuing at the end of the period;

(4)the deposit does not constitute a default under any other agreement binding on the Company;

(5)the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940;

(6)in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the U.S. Internal Revenue Service a ruling, or (ii) since the Issue Date there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Securityholders (and their beneficial owners) shall not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance and shall be subject to U.S. 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;

(7)in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Securityholders (and their beneficial owners) shall not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and shall be subject to U.S. 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; and

(8)the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance of the Securities as contemplated by this Article 8 have been complied with.

Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article 3.

Section 8.03    Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities.

Section 8.04    Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon written request any money or securities held by them at any time which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required for the Company to exercise its legal defeasance option or its covenant defeasance option pursuant to this Article 8.

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look solely to the Company for payment as general creditors.

Section 8.05    Indemnity for Government Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

Section 8.06    Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under the Note Documents shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

Section 9.01    Without Consent of Holders. The Company, the Subsidiary Guarantors, the Trustee and the Collateral Trustee may amend any of the Note Documents without notice to or consent of any Securityholder:

(1)to cure any ambiguity, omission, defect or inconsistency;

(2)to provide for the assumption by a successor corporation of the obligations of the Company or the Subsidiary Guarantors under this Indenture or the other Note Documents as provided in Article 5;

(3)to provide for uncertificated Securities in addition to or in place of certificated Securities; provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code;

(4)to add guarantees or Collateral with respect to the Securities (including any Subsidiary Guarantee), or release guarantees or Collateral with respect to the Securities (including any Subsidiary Guarantee) in the manner provided in this Indenture and the other Note Documents;

(5)with respect to the Note Documents establishing Parity Liens, as provided in the Intercreditor Agreement or the Collateral Trust Agreement;

(6)to provide for the issuance of Additional Securities (in accordance with the limitations set forth in this Indenture);

(7)to add to the covenants of the Company for the benefit of the Holders or to surrender any right or power herein conferred upon the Company or any Subsidiary Guarantor;

(8)to make any change that does not adversely affect the rights of any Holder under any Note Document in any material respect; provided, however, that any change to this Indenture to conform it to the Description of Second Lien Notes shall not be deemed to adversely affect such rights;

(9)to make, complete or confirm any grant of Collateral permitted or required by this Indenture or any of the Note Documents establishing Parity Liens; or

(10)to conform the text of this Indenture, the Subsidiary Guarantees or the other Note Documents (a) to any provision in the Description of Second Lien Notes to the extent that such text constitutes an unintended conflict with, or is inconsistent with, the description of the corresponding provision in the Description of Second Lien Notes or (b) as may be necessary or advisable to preserve and confirm the relative priorities of the Secured Debt Documents as such priorities are contemplated by and set forth in the Intercreditor Agreement, in each case as described in an Officers’ Certificate.

In addition, the Intercreditor Agreement and the Collateral Trust Agreement may be amended in accordance with their terms and without the consent of any Holder, the Trustee or the Collateral Trustee with the consent of the parties thereto or otherwise in accordance with their terms, including to add additional Indebtedness as Priority Lien Debt, Parity Lien Debt or Junior Lien Debt and add other parties (or any authorized agent thereof or trustee therefor) holding such Indebtedness thereto and to establish that the Liens on any Collateral securing such Indebtedness shall rank equally with (or junior to) the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as applicable, then outstanding, in each case to the extent permitted by the applicable Secured Debt Documents.

After an amendment under this Section becomes effective, the Company shall mail or otherwise deliver in accordance with the applicable procedures of DTC to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section.

Section 9.02    With Consent of Holders. Subject to other exceptions set forth in this Indenture, the Company, the Subsidiary Guarantors and the Trustee may amend any of the Note Documents without prior notice to any Securityholder but with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities). Without the consent of each Securityholder affected thereby, however, an amendment may not:

(1)reduce the amount of Securities whose Holders must consent to an amendment;

(2)reduce the rate of or extend the time for payment of interest on any Security;

(3)reduce the principal of or extend the Stated Maturity of any Security;

(4)reduce the premium payable upon a required purchase (to the extent the Company has at the time become obligated by the terms of this Indenture to effect a required purchase) or the redemption of any Security or change the date on which any Security may be redeemed in accordance with Article 3 of this Indenture and paragraph 5 of the Securities (except, in any case, for the redemption notice period);

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

(6)impair the contractual right of any Securityholder to receive payment of principal of and interest on such Securityholder’s Security on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Securityholder’s Security;

(7)make any change in Section 6.04 or 6.07 or the second sentence of this Section; or

(8)make any change in any Subsidiary Guarantee that could adversely affect such Securityholder.

In addition, the consent of Holders representing at least 66⅔% in principal amount of outstanding Securities will be required to release the Liens for the benefit of the Holders of the Securities on all or substantially all of the Collateral, other than in accordance with the Note Documents. If Holders of at least 66⅔% in principal amount of outstanding Securities so consent to the release of Collateral, the Trustee or Collateral Trustee, as the case may be, will be entitled to vote the total principal amount of Securities then outstanding as a block in respect of any vote required for such release under the Security Documents.

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

After an amendment under this Section becomes effective, the Company shall mail or otherwise deliver in accordance with the applicable procedures of DTC to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section.

Section 9.03    [Reserved].

Section 9.04    Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder shall bind the Holder and every subsequent Holder or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

Section 9.05    Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Company may require the Holder to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

Section 9.06    Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or

immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture and the other Note Documents and that such amendment is the legal, valid and binding obligation of the Company and any Subsidiary Guarantor, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof.

Section 9.07    Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid or agreed to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

Section 10.01    Security Interest.

(a)The due and punctual payment of the Obligations on the Securities and the Obligations of the Subsidiary Guarantors under the Subsidiary Guarantees, when and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest (including interest and other Obligations accruing during the pendency of any bankruptcy, insolvency, receivership or other similar proceeding, regardless of whether allowed or allowable in such proceeding), on the Securities, the Subsidiary Guarantees and performance and payment of all other obligations of the Company and the Subsidiary Guarantors to the Holders or the Trustee and the Collateral Trustee under the Note Documents, according to the terms hereunder or thereunder, are secured as provided in the Security Documents. In furtherance of the foregoing, the Company and each Subsidiary Guarantor (a) have entered into the Collateral Trust Agreement, the Intercreditor Agreement and the Pledge Agreement and (b) have delivered or will, on or prior to the Issue Date, deliver to the Collateral Trustee (or the Priority Lien Agent in accordance with the Intercreditor Agreement) all certificates and other instruments and documents required under the Pledge Agreement to be delivered to the Collateral Trustee and (c) have authorized or will, on or prior to the Issue Date, authorize the filing, registration and recording of all Uniform Commercial Code financing statements required by applicable law to be filed, registered or recorded to perfect the Parity Liens created under the Pledge Agreement to the extent required by the Pledge Agreement, the Intercreditor Agreement and this Indenture. The Company and each of the Subsidiary 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. The Company and the Subsidiary Guarantors hereby agree that, subject to Section 10.6, the Intercreditor Agreement and the Collateral Trust Agreement, the Collateral Trustee shall hold the Collateral on behalf of and for the benefit of all of the Holders and the other holders of Parity Lien Obligations.

(b)Each Holder, by its acceptance of a Security and of the Subsidiary Guarantees, consents and agrees to the terms of the Intercreditor Agreement, the Collateral Trust Agreement 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 Wilmington Trust, National Association as the Trustee and as the Collateral Trustee. The Trustee hereby authorizes and appoints Wilmington Trust, National Association as Collateral Trustee, and each Holder and the Trustee direct the Collateral Trustee to enter into any Security Documents to which it is not already party (including any amendments thereto contemplated by Section 7.1 of the Collateral Trust Agreement and any security documents to secure additional Parity Lien Debt in accordance with Section 5.3 of the Collateral Trust Agreement, all as more particularly described in the Collateral Trust Agreement, and any joinders to any Security Documents) and to perform its obligations and exercise its rights thereunder in accordance therewith, subject to the terms and conditions thereof, including, 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 Securities and the Subsidiary Guarantees of the Subsidiary Guarantors, acknowledges that, as more fully set forth in the Security Documents, the Collateral as now or hereafter constituted shall be held, subject to the Intercreditor Agreement and the Collateral Trust Agreement, for the benefit of all the holders of Parity Lien Obligations, 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 Intercreditor Agreement, the Collateral Trust Agreement, the Security Documents and actions that may be taken thereunder.

Section 10.02    Post-Issue Date Collateral Requirements.

(a)The Company and the applicable Subsidiary Guarantors are parties to certain Mortgages that secure the Existing Second Lien Notes and that will, upon the execution and recording of certain amendments thereto, establish Parity Liens on the Collateral. Accordingly, on or before January 5, 2018, the Company shall, or shall cause the applicable Subsidiary Guarantors to, execute and deliver amendments to such Mortgages to the appropriate local counsel’s office for recording or to the applicable recording office for recording (such amendments, the “Mortgage Amendments”). The Company shall make a filing on Form 8-K with the SEC within five Business Days after January 5, 2018 indicating the Company’s compliance with the requirement in the immediately preceding sentence. The Company hereby covenants and confirms as follows: (i) that such Mortgages have been filed for record in the real estate records, mortgage records or other appropriate records of each jurisdiction where any part of the Collateral constituting Oil and Gas Properties of the Company and its Restricted Subsidiaries are situated, and (ii) that upon the Mortgage Amendments being filed for record in the real estate records, mortgage records or other appropriate records of each such jurisdiction, such Mortgages will create for the benefit of the parties secured thereby (including the Holders) valid and perfected Parity Liens on the Oil and Gas Properties subject to such Mortgages (as amended by such Mortgage Amendments), which Oil and Gas Properties had, as of November 1, 2017, a PV-9 value equal to at least 90% of the PV-9 value of Proved Reserves attributable to the Oil and Gas Properties of the Company and its Restricted Subsidiaries, as evaluated in the most recent Reserve Report, after giving effect to exploration and production activities, acquisitions, dispositions and production since the date of such Reserve Report. The Company shall, or shall cause the applicable Subsidiary Guarantors to, (i) cause appropriate counsel to execute and deliver to the Collateral Trustee Opinions of Counsel (subject to customary assumptions and qualifications) in form reasonably satisfactory to the Collateral Trustee on the date of delivery of such Mortgage Amendments for recording substantially to the effect that, by virtue of the recording of such Mortgage Amendments and the filing of appropriate Uniform Commercial Code financing statements (or amendments to existing financing statements), the Collateral Trustee has or will have a valid and perfected lien for the benefit of the Holders with respect to the Oil and Gas Properties subject to such Mortgages (as amended by such Mortgage Amendments), and (ii) promptly pay any required taxes or fees in connection with the recordation and filing of such Mortgage Amendments. The Company shall, or shall cause the applicable

Subsidiary Guarantor to, send written evidence of the recording of such Mortgage Amendments promptly after the receipt of evidence of such recording to the Collateral Trustee.

(b)To the extent required by the Security Documents for each deposit account, securities account and commodity account that the Company or any Subsidiary Guarantor at any time maintains, the Company shall, or shall cause the applicable Subsidiary Guarantor to, pursuant to a customary control agreement in form and substance reasonably satisfactory to the Collateral Trustee, cause the depository bank that maintains such deposit account, securities intermediary that maintains such securities account, or commodities intermediary that maintains such commodity account, as applicable, to agree to comply at any time with instructions from the Collateral Trustee (or, prior to the Discharge of Priority Lien Obligations (as defined in the Intercreditor Agreement), the Priority Lien Agent, as gratuitous bailee for the Secured Parties) to such depository bank, securities intermediary or commodities intermediary directing the disposition of funds from time to time credited to any such deposit account, directing the transfer or redemption of a financial asset credited to any such deposit account or directing the application of any value distributed on account of any commodity contract carried in any such commodity account, in each case without further consent of the Company or such Subsidiary Guarantor, or take such other action as the Collateral Trustee may approve in order to perfect the Collateral Trustee’s security interest in such deposit account, securities account or commodity account. The Company hereby covenants and confirms that each deposit account, securities account and commodity account existing on the Issue Date that is required by the Security Documents to be subject to a customary control agreement is subject to such a customary control agreement that has been delivered to the Collateral Trustee. With respect to any such deposit account, securities account or commodity account opened after the Issue Date, the required control agreement shall be delivered substantially contemporaneously with the opening thereof. On the date that any such control agreement is executed, the Company shall cause appropriate counsel to execute and deliver to the Collateral Trustee an Opinion of Counsel in form reasonably satisfactory to the Collateral Trustee and substantially to the effect that the Collateral Trustee has a valid and perfected lien, perfected by “control,” with respect to each such deposit account, securities account or commodity account.

(c)Any Security Documents providing for the Parity Liens entered into after the Issue Date shall be substantially in the form of, and grant security interests in the same assets as, the corresponding security documents securing the Priority Lien Obligations, or to the extent there are no such corresponding security documents, the form of the corresponding security documents securing the Priority Lien Obligations in place on the Issue Date, in each case, with such changes as are reasonably necessary to reflect the terms of the Intercreditor Agreement 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 of the Company. Neither the Trustee nor the Collateral Trustee shall have any duty or obligation to determine whether deletions or modifications of representations, warranties and covenants with respect to security documents establishing Liens are customary.

Section 10.03    Further Assurances; Liens on Additional Property.

(a)The Company and each of the Subsidiary Guarantors shall do or cause to be done all acts and things that may be required, or that the Collateral Trustee from time to time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the holders of the Parity Lien Obligations, duly created and enforceable and perfected Liens upon the Collateral (including any property or assets constituting Collateral that are acquired or otherwise become, or are required by any Parity Lien Document to become, Collateral after the Issue Date), in each case, as contemplated by, and with the Lien priority required under, the Parity Lien Documents. In connection with any merger or

consolidation of the Company or any Subsidiary Guarantor, the Company or such Subsidiary Guarantor shall take such action as may be reasonably necessary to cause any newly acquired property and assets to be made subject to the Parity Liens in the manner and to the extent required under the Security Documents.

(b)Upon the reasonable request of the Collateral Trustee or any Parity Lien Representative at any time and from time to time, the Company and each of the Subsidiary Guarantors will promptly execute, acknowledge and deliver such Security Documents, instruments, certificates, notices and other documents, and take such other actions as shall be reasonably required, or that the Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred, in each case as contemplated by the Parity Lien Documents for the benefit of the holders of Parity Lien Obligations; provided that no such Security Document, instrument or other document shall be materially more burdensome upon the Company and the Subsidiary Guarantors than the Parity Lien Documents executed and delivered (or required to be executed and delivered after the Issue Date within the timeframes set forth herein) by the Company and the Subsidiary Guarantors in connection with the issuance of the Original Securities on the Issue Date.

(c)In addition, from and after the Issue Date, if the Company or any Subsidiary Guarantor acquires any property or asset that constitutes collateral for the Priority Lien Debt or Junior Lien Debt, and any Priority Lien Document or Junior Lien Document, as applicable, requires any supplemental Security Document for such collateral or other actions to achieve a perfected Lien on such collateral, then the Company shall, or shall cause the applicable Subsidiary Guarantor to, promptly (but in any event no later than the date that is 20 Business Days after the date on which such supplemental Security Documents are executed and delivered (or other action taken) under such Priority Lien Documents or Junior Lien Documents, as applicable), to the extent permitted by applicable law, execute and deliver to the Collateral Trustee appropriate Security Documents (or amendments thereto) in such form as shall be necessary to grant the Collateral Trustee a valid, enforceable and perfected second-priority Lien on such property or asset or take such other actions in favor of the Collateral Trustee as shall be reasonably necessary to grant a valid, enforceable and perfected Lien on such collateral to the Collateral Trustee for the benefit of the holders of Parity Lien Obligations, subject to the terms of this Indenture, the Intercreditor Agreement and the other Note Documents. Additionally, subject to this Indenture, the Intercreditor Agreement and the other Note Documents, if the Company or any Subsidiary Guarantor creates any additional Lien upon any property or asset that is required to constitute Collateral, or takes any actions to perfect any Lien on Collateral, in each case for the benefit of the holders of the Priority Lien Debt or the holders of Junior Lien Debt, after the Issue Date, the Company or such Subsidiary Guarantor, as applicable, shall, to the extent permitted by applicable law, within 20 Business Days after such Lien is granted or other action taken, grant a valid and enforceable second-priority Lien upon such property or asset, or take such perfection actions, as applicable, for the benefit of the Holders and obtain all such related deliverables as shall have been delivered to the Priority Lien Agent or Junior Lien Agent, as applicable, in each case as security for the obligations of the Company with respect to the Securities, the obligations of the Subsidiary Guarantors under the Subsidiary Guarantees and the performance of all other obligations of the Company and the Subsidiary Guarantors under the Note Documents. Neither the Trustee nor the Collateral Trustee shall have a duty to monitor the status of any Collateral or any future acquisition of property and rights that constitute Collateral, nor shall the Trustee or the Collateral Trustee have any duty to properly perfect the security interests. Notwithstanding the foregoing, to the extent that any Lien on any Collateral is perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the Priority Lien Agent, or of agents or bailees of the Priority Lien Agent (in each case as gratuitous bailee or agent of the Collateral Trustee), the perfection

actions and related deliverables described in this Section 10.03(c) shall not be required other than with respect to control agreements, which shall be subject to an additional 60-day grace period.

(d)The Company shall deliver to the Collateral Trustee semi-annually on or before May 1 and November 1 in each calendar year, beginning May 1, 2018, an Officers’ Certificate certifying, as of the date of such certificate, the amount of Oil and Gas Properties included in the Collateral, expressed as a percentage of the PV-9 value of Proved Reserves attributable to the Oil and Gas Properties of the Company and its Restricted Subsidiaries, as evaluated in the most recent Reserve Report, after giving effect to exploration and production activities, acquisitions, dispositions and production since the date of such Reserve Report; provided, that in the event the percentage of the PV-9 value so certified is not at least equal to 90% of the PV-9 value of such Proved Reserves, the Company shall, or shall cause the applicable Restricted Subsidiary to, within 60 days following delivery of such certificate, execute and deliver to the Collateral Trustee: (i) such executed Mortgages or amendments or supplements to prior Mortgages naming the Collateral Trustee, as mortgagee or beneficiary, as may be necessary to cause such 90% requirement to be satisfied, (ii) satisfactory evidence of the delivery of all executed Mortgages (or amendments or supplements thereto) to the appropriate local counsel’s office for recording or the applicable recording office for recording (and payment of any taxes or fees in connection therewith) and (iii) an additional Officers’ Certificate certifying, as of the date of such certificate, that the amount of Oil and Gas Properties included in the Collateral, expressed as a percentage of the PV-9 value of such Proved Reserves, is at least equal to 90%. The Company shall send written evidence of the recording of any such Mortgages (or amendments or supplements thereto) promptly after the receipt thereof to the Collateral Trustee. The Company will also cause to be delivered to the Collateral Trustee, on the date of delivery of such Mortgages, an Opinion of Counsel (by appropriate counsel and subject to customary assumptions and qualifications) to the effect that, upon recording of such Mortgages and the filing of appropriate Uniform Commercial Code financing statements (or amendments to existing financing statements), the Collateral Trustee will have a valid and perfected lien with respect to the Oil and Gas Properties subject to such Mortgages.

(e)Without limitation of any other obligations under this Section 10.03, promptly following the execution of any Mortgage, the Company shall file such Uniform Commercial Code financing statements necessary to perfect the security interest in any personal property Collateral granted under such Mortgage in the appropriate jurisdiction.

Section 10.04    Intercreditor Agreement. This Article 10 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor Agreement. The Company and each Subsidiary 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. The Company shall, on the Issue Date, execute and deliver any certificates and other instruments and documents required under the Intercreditor Agreement to be delivered to the Priority Lien Agent or the Second Lien Collateral Trustee (each as defined in the Intercreditor Agreement) in connection with the designation of the Holders as additional holders of Second Lien Obligations (as defined in the Intercreditor Agreement). Each Holder, by its acceptance of the Securities (a) consents to the subordination of Liens provided for in the Intercreditor Agreement, (b) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Intercreditor Agreement and (c) authorizes and instructs the Trustee and Collateral Trustee to join and become a party to the Intercreditor Agreement on behalf of the Holders as Second Lien Secured Parties (as defined in the Intercreditor Agreement). In addition, each Holder authorizes and instructs the Collateral Trustee to enter into any amendments or joinders to the Intercreditor Agreement or Collateral Trust Agreement, to add the Securities as Parity Lien Debt and without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Debt, Parity Lien Debt or Junior Lien Debt and add other parties (or any

authorized agent or trustee therefor) holding such Indebtedness thereto and to establish that the Lien on any Collateral securing such Indebtedness ranks equally with the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt or Junior Lien Debt, as applicable, then outstanding, in each case, where the Incurrence of such Secured Debt is permitted by this Indenture. The foregoing provisions are intended as an inducement to the lenders under the Priority Lien Credit Agreement to continue to extend credit to the Company and certain of the Subsidiaries, and such lenders are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement.

Section 10.05    Collateral Trust Agreement. This Article 10 and the provisions of each Security Document are subject to the terms, conditions and benefits set forth in the Collateral Trust Agreement. The Company and each Subsidiary Guarantor consents to, and agrees to be bound by, the terms of the Collateral Trust Agreement and to perform its obligations thereunder in accordance with the terms therewith. The Company shall, on the Issue Date, execute and deliver any certificates and other instruments and documents required under the Collateral Trust Agreement to be delivered to the Collateral Trustee in connection with the designation of the Holders as additional holders of Parity Lien Debt. Each Holder, by its acceptance of the Securities (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Collateral Trust Agreement, (b) authorizes and instructs the Collateral Trustee to join and become a party to the Collateral Trust Agreement as Collateral Trustee on behalf of the Holders and the other holders of Parity Lien Obligations and (c) authorizes and instructs the Trustee to join and become a party to the Collateral Trust Agreement as Trustee on behalf of the Holders and authorizes and instructs the Trustee to perform its obligations thereunder as the Parity Lien Representative for the Holders.

Section 10.06    Release of Liens in Respect of Securities. The Collateral Trustee’s Parity Liens upon the Collateral will no longer secure the Securities outstanding under this Indenture or any other Obligations under the Note Documents, and the right of the Holders to the benefits and proceeds of the Collateral Trustee’s Parity Liens on the Collateral will terminate and be discharged:

(a)upon satisfaction and discharge of this Indenture in accordance with Section 8.01;

(b)upon exercise of the legal defeasance option or covenant defeasance option in accordance with Article 8;

(c) upon payment in full in cash and discharge of all Securities outstanding under this Indenture and all other Obligations that are outstanding, due and payable under this Indenture and the other Note Documents at the time the Securities are paid in full in cash and discharged (other than contingent indemnity obligations for which no claim has been made);

(d)as to any Collateral of the Company or a Subsidiary Guarantor that is sold, transferred or otherwise disposed of by the Company or any Subsidiary Guarantor to a Person that is not (either before or after such sale, transfer or disposition) the Company or a Subsidiary of the Company in a transaction or other circumstance that does not violate Section 4.07(a) and is otherwise permitted by all of the Note Documents, at the time of such sale, transfer or other disposition to the extent of the interest sold, transferred or otherwise disposed of; provided that the Collateral Trustee’s Liens upon the Collateral will not be released if the sale or disposition is subject to Section 5.01;

(e)in whole or in part, with the consent of the Holders of the requisite percentage of aggregate principal amount of Securities in accordance with Section 9.02;

(f)with respect to the assets of any Subsidiary Guarantor, at the time that such Subsidiary Guarantor is released from its Subsidiary Guarantee in accordance with Section 11.06; or

(g)if and to the extent required by Section 4.1(a) of the Collateral Trust Agreement or Section 4.01(a) of the Intercreditor Agreement.

Upon receipt of an Officers’ Certificate and Opinion of Counsel, the Collateral Trustee shall execute, deliver or acknowledge any necessary or proper instruments of termination, satisfaction or release prepared by the Company of any Collateral permitted to be released pursuant to this Section 10.06.

Section 10.07    Insurance. The Company hereby covenants and confirms that as of the Issue Date the Collateral Trustee is named (through an endorsement or amendment to the applicable policy) as an additional insured on all liability insurance policies of the Company and the Subsidiary Guarantors for which the Priority Lien Agent is named as an additional insured and the Collateral Trustee is named as an additional lender loss payee and, if applicable, mortgagee on all property and casualty insurance policies of the Company and the Subsidiary Guarantors for which the Priority Lien Agent is so named. If at any time there ceases to be a Priority Lien Credit Agreement, the Company and the Subsidiary Guarantors shall continue to cause the Collateral Trustee to be so named as contemplated in this sentence with respect to any liability, property and casualty insurance policies that insure the Collateral. The Company and the Subsidiary Guarantors shall exercise commercially reasonable efforts to cause the insurance providers of such policies to endeavor to give 30 days’ notice to the Collateral Trustee of cancellation of all such property and casualty insurance policies of the Company and the Subsidiary Guarantors (or at least 10 days’ prior written notice in the case of cancellation of such issuance due to non-payment).

Section 10.08    Collateral Trustee.

(a)The Collateral Trustee will hold (directly or through co-trustees or agents) and, subject to the terms of the Intercreditor Agreement, will be entitled to enforce all Liens on the Collateral created by the Security Documents.

(b)Except as provided in the Collateral Trust Agreement or as directed by an Act of Parity Lien Debtholders in accordance with the Collateral Trust Agreement, the Collateral Trustee will not be obligated:

(i)to act upon directions purported to be delivered to it by any Person;

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

(iii)to take any other action whatsoever with regard to any or all of the Security Documents, the Liens created thereby or the Collateral.

The Company will deliver to each Parity Lien Representative copies of all Security Documents delivered to the Collateral Trustee.

(c)By accepting a Security, each Holder is deemed to authorize the Collateral Trustee to release or subordinate any Collateral that is permitted to be sold, reclassified or released or be subject to a Priority Lien pursuant to the terms of this Indenture and the Security Documents. By

accepting a Security, each Holder is deemed to authorize the Collateral Trustee to execute and deliver to the Company, at the Company’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Company in connection with any sale, reclassification or other disposition of Collateral to the extent such sale, reclassification or other disposition, and such release of Liens, is permitted by the terms of this Indenture, the Security Documents and the Intercreditor Agreement.

(d)Neither the Trustee nor the Collateral Trustee nor any of their respective officers, directors, employees, attorneys or agents shall be responsible for (i) perfecting, maintaining, monitoring, preserving or protecting the security interest or Lien granted under the Security Documents or any agreement or instrument contemplated hereby or thereby, (ii) the filing, re-filing, recording, re-recording or continuing of any document, financing statement, Mortgage, assignment, notice, instrument of further assurance or other instrument in any public office at any time or times or (iii) providing, maintaining, monitoring or preserving insurance on or the payment of taxes with respect to the Collateral. The actions described in clauses (i) through (iii) shall be the sole responsibility of the Company and the Subsidiary Guarantors.

(e)Neither the Trustee nor the Collateral Trustee nor any of their respective officers, directors, employees, attorneys or agents will be responsible or liable for the existence, genuineness, value or protection of any Collateral, for the legality, enforceability, effectiveness, or sufficiency of the Collateral Documents, for the creation, perfection, priority, sufficiency or protection of any Lien, including payment of any Taxes, charges or assessments upon the Collateral or otherwise as to the maintenance of the Collateral, or for any defect or deficiency as to any such matters, or, except as may be provided in the Collateral Trust Agreement, for any failure to demand, collect, foreclose or realize upon or otherwise enforce any of the Liens or Collateral Documents or any delay in doing so. Neither the Trustee nor the Collateral Trustee nor any of their respective officers, directors, employees, attorneys or agents will be responsible or liable for making any filings or recordings to perfect or maintain the perfection of the Collateral Trustee’s Lien in the Collateral, including without limitation, the filing of any Uniform Commercial Code financing statements, continuation statements, Mortgages or any other filings.

(f)In acting hereunder and under the other Note Documents, the Holders, the Company and the Subsidiary Guarantors agree that the Collateral Trustee shall be entitled to the rights, privileges, protections, immunities, indemnities and benefits provided to the Trustee hereunder as if such were provided to the Collateral Trustee.

Section 11.01    Subsidiary Guarantees. Each Subsidiary Guarantor, jointly and severally, as primary obligor and not merely as surety, hereby irrevocably, fully and unconditionally Guarantees on a senior secured second lien basis to each Holder and to the Trustee and the Collateral Trustee and their respective successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Securities (all the foregoing obligations hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary

Guarantor, and that such Subsidiary Guarantor shall remain bound under this Article 11 notwithstanding any extension or renewal of any such Guaranteed Obligation.

Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder, the Trustee or the Collateral Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities, the other Note Documents or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (d) the release of any security held by any Holder, the Trustee or the Collateral Trustee for the Guaranteed Obligations or any of them; (e) the failure of any Holder, Trustee or the Collateral Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (f) except as provided in Section 11.06, any change in the ownership of such Subsidiary Guarantor.

Each Subsidiary Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder, the Trustee or the Collateral Trustee to any security held for payment of the Guaranteed Obligations.

Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder, the Trustee or the Collateral Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder, the Trustee or the Collateral Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder, the Trustee or the Collateral Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Subsidiary Guarantor shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders, the Trustee or the Collateral Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations

(but only to the extent not prohibited by law) and (iii) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee.

Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders, the Trustee and the Collateral Trustee, on the other hand, (x) the maturity of the Guaranteed Obligations Guaranteed hereby may be accelerated as provided in Article 6 for the purposes of such Subsidiary Guarantor’s Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations Guaranteed hereby, and (y) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section.

Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee, the Collateral Trustee or any Holder in enforcing any rights under this Section.

Section 11.02    Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum, aggregate amount of the obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed by such Subsidiary Guarantor without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 11.03    Successors and Assigns. This Article 11 shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee, the Collateral Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder, the Trustee or the Collateral Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 11.04    No Waiver. Neither a failure nor a delay on the part of either the Trustee, the Collateral Trustee or the Holders in exercising any right, power or privilege under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee, the Collateral Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise.

Section 11.05    Modification. No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.

Section 11.06    Release of Subsidiary Guarantor. The Guarantee of a Subsidiary Guarantor shall be automatically and unconditionally released and discharged:

(a)upon satisfaction and discharge of this Indenture in accordance with Section 8.01;

(b)upon exercise of the legal defeasance option or covenant defeasance option in accordance with Article 8;

(c)upon payment in full in cash and discharge of all Securities outstanding under this Indenture and all other Obligations that are outstanding, due and payable under this Indenture and the other Note Documents at the time the Securities are paid in full in cash and discharged (other than contingent indemnity obligations for which no claim has been made);

(d)in connection with any sale, transfer or other disposition of (x) the Capital Stock of such Subsidiary Guarantor, after which such Subsidiary Guarantor is no longer a Restricted Subsidiary or (y) all or substantially all of the assets of such Subsidiary Guarantor, in each case, to a Person that is not (either before or after such sale, transfer or disposition) the Company or a Subsidiary of the Company in a transaction or other circumstance that does not violate Section 4.07(a) and is otherwise permitted by all of the Note Documents, at the time of such sale, transfer or other disposition; or

(e)upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture.

Upon receipt of an Officers’ Certificate and an Opinion of Counsel, the Trustee shall execute, deliver or acknowledge any necessary or proper instruments of termination or release prepared by the Company or any Subsidiary Guarantor permitted to be released pursuant to this Section 11.06.

The Company shall pay interest semiannually on March 31 and September 30 of each year, commencing on March 31, 2018. Interest on the Securities shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from December 6, 2017. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal at the rate borne by the Securities plus 1% per annum, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

2.    Method of Payment

Payments in respect of the Securities represented by a Global Security (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company shall make all payments in respect of a certificated Security (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security shall be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3.    Paying Agent and Registrar

Initially, Wilmington Trust, National Association (the “Trustee”), shall act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any Wholly-Owned Subsidiary may act as Paying Agent, Registrar or co-registrar.

4.    Indenture

The Company issued the Securities under an Indenture dated as of December 6, 2017 (“Indenture”), among the Company, the Subsidiary Guarantors, the Trustee and the Collateral Trustee. The terms of the Securities include those stated in the Indenture and those expressly made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the Issue Date (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms.

The Securities are general senior secured second lien obligations of the Company. The Company shall be entitled, subject to its compliance with Sections 4.03 and 4.10 of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Securities issued on the Issue Date and any Additional Securities shall be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur or guarantee additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; engage in transactions with affiliates; transfer or sell assets; incur liens; restrict dividends or other payments of subsidiaries; and consolidate, merge or transfer all or substantially all of their assets and the assets of their subsidiaries. These covenants are subject to important exceptions and qualifications.

5.    Optional Redemption

(a)    Optional Redemption. Except as set forth below, the Company shall not be entitled to redeem the Securities prior to March 31, 2019. On and after March 31, 2019, the Company shall be entitled at its option to redeem all or a portion of the Securities at any time or from time to time upon not less than 30 nor more than 60 days’ prior notice sent by electronic transmission or by first-class mail to each Holder’s registered address, at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest 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 occurring on or prior to the redemption date), if redeemed during the 12-month period commencing on March 31 of the years set forth below:

(b)    Optional Redemption Upon Stock Offerings. Prior to March 31, 2019, the Company may at its option on one or more occasions redeem Securities (which include Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Securities (which include Additional Securities, if any) issued under the Indenture at a redemption price (expressed as a percentage of principal amount) of 109.25%, plus accrued and unpaid interest to but not including the redemption date, with the net cash proceeds from one or more Stock Offerings; provided, however, that

(1)    at least 65% of such aggregate principal amount of Securities (which include Additional Securities, if any) remains outstanding immediately after the occurrence of each such redemption (excluding Securities held, directly or indirectly, by the Company or its Affiliates); and

(2)    each such redemption occurs within 60 days after the date of consummation of the related Stock Offering.

(c)    Make-Whole Redemption. At any time prior to March 31, 2019, upon not less than 30 nor more than 60 days’ prior notice sent by electronic transmission or by first-class mail to each Holder’s registered address, the Company may redeem the Securities, in whole or in part, at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium, plus accrued and unpaid interest, if any, to 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 occurring on or prior to the redemption date). The Company will calculate the Applicable Premium prior to such redemption date and deliver to

the Trustee an Officers’ Certificate setting forth the redemption price and Applicable Premium, showing the calculation of each in reasonable detail.

(d)    “Applicable Premium” means, with respect to a Security on any date of redemption, the greater of (i) 1.0% of the principal amount of such Security; and (ii) the excess, if any, of (a) the present value as of such date of redemption of (i) the redemption price of such Security on March 31, 2019 plus (ii) all required interest payments due on such Security through March 31, 2019 (excluding accrued but unpaid interest to the date of redemption), computed using a discount rate equal to the Treasury Rate as of such date of redemption plus 50 basis points, over (b) the then-outstanding principal of such Security.

(e)     “Treasury Rate” means as of any date of redemption of Securities the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two Business Days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source or similar market data)) most nearly equal to the period from the redemption date to March 31, 2019; provided, however, that if the period from the redemption date to March 31, 2019 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the redemption date to March 31, 2019 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

6.    Notice of Redemption

Notice of redemption shall be mailed at least 30 days but not more than 60 days before the redemption date to each Holder to be redeemed at its registered address. Securities in denominations larger than $2,000 principal amount may be redeemed in part but only in whole multiples of $1,000 in excess thereof. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

7.    Put Provisions

Upon a Change of Control, any Holder shall have the right to cause the Company to repurchase all or any part of the Securities of such Holder at a purchase price equal to 101% of the principal amount of the Securities to be repurchased on the date of purchase plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

8.    Designation of Security

The Securities and the Subsidiary Guarantees shall constitute “Senior Indebtedness,” and the Company and the Subsidiary Guarantors hereby designate the Securities and the Subsidiary Guarantees as “Designated Senior Indebtedness” of the Company and the Subsidiary Guarantors, for purposes of the Existing Subordinated Notes Indentures. The Securities and the Subsidiary Guarantees shall be superior in right of payment to the Existing Subordinated Notes and the Guarantees thereof.

9.    Guarantees

The payment by the Company of the principal of, and premium (if any) and interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior secured second lien basis by each of the Subsidiary Guarantors on the terms set forth in the Indenture.

10.    Denominations; Transfer; Exchange

The Securities are in registered form without coupons in minimum denominations of $2,000 principal amount and whole multiples of $1,000.

The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date.

11.    Persons Deemed Owners

The registered Holder of this Security may be treated as the owner of it for all purposes.

12.    Unclaimed Money

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

13.    Discharge and Defeasance

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture, including the Subsidiary Guarantees, if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

The Events of Default with respect to the Notes are set forth in Section 6.01 of the Indenture. Upon the occurrence of an Event of Default, the rights and obligations of the Company, the Subsidiary Guarantors, the Trustee, the Collateral Trustee and the Holders are as provided in the Indenture.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from

Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.

16.    Trustee Dealings with the Company

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

17.    No Recourse Against Others

A director, officer, employee, stockholder, incorporator, or member, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities, any Subsidiary Guarantee, or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.
