(1) if the Parent Guarantor or any Restricted Subsidiary:

(a) has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such Indebtedness and the use of proceeds thereof as if such Indebtedness had been Incurred on the first day of such period and such proceeds had been applied as of such date (except that in making such computation, the amount of Indebtedness under any revolving Credit Facility outstanding on the date of such calculation will be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was outstanding or (ii) if such revolving Credit Facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such revolving Credit Facility to the date of such calculation, in each case, provided that such average daily balance shall take into account any repayment of Indebtedness under such revolving Credit Facility as provided in clause (b)); or

(b) has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of the period, including with the proceeds of such new Indebtedness, that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of Indebtedness (in each case other than Indebtedness Incurred under any revolving Credit Facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness as if such discharge had occurred on the first day of such period;

(2) if, since the beginning of such period, the Parent Guarantor or any Restricted Subsidiary has made any Asset Disposition or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition, the Consolidated EBITDAX for such period will be reduced by an amount equal to the

13

Consolidated EBITDAX (if positive) directly attributable to the assets which are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDAX (if negative) directly attributable thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Parent Guarantor or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Parent Guarantor and its continuing Restricted Subsidiaries in connection with or with the proceeds from such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Parent Guarantor and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

(3) if, since the beginning of such period, the Parent Guarantor or any Restricted Subsidiary (by merger or otherwise) has made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged with or into the Parent Guarantor or a Restricted Subsidiary) or an acquisition (or will have received a contribution) of assets, including any acquisition or contribution of assets occurring in connection with a transaction causing a calculation to be made under this Indenture, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of business, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition or contribution had occurred on the first day of such period; and

(4) if, since the beginning of such period, any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Parent Guarantor or any Restricted Subsidiary since the beginning of such period) made any Asset Disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or (3) above if made by the Parent Guarantor or a Restricted Subsidiary during such period, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto as if such Asset Disposition or Investment or acquisition of assets had occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in accordance with Regulation S-X under the Securities Act. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the average rate in effect from the beginning of such period to the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Parent Guarantor, the interest rate shall be calculated by applying such optional rate chosen by the Parent Guarantor. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Parent Guarantor may designate.

14

(6) consolidated exploration (including all drilling, completion, geological and geophysical costs) and abandonment expense of the Parent Guarantor and its Restricted Subsidiaries;

(7) the amount of any non-controlling interest consisting of income attributable to non-controlling interests of third parties in any non-Wholly Owned Subsidiary that is a Restricted Subsidiary that is not included or deducted (and not added back) in calculating such Consolidated Net Income, but excluding cash distributions made in respect of such non-controlling interests; and

(7) the consolidated interest expense of the Parent Guarantor and its Restricted Subsidiaries that was capitalized during such period; and

(8) all dividends paid or payable in cash, Cash Equivalents or Indebtedness or accrued during such period on any series of Disqualified Stock of the Parent Guarantor or on Preferred Stock of its Restricted Subsidiaries payable to a party other than the Parent Guarantor or a Wholly-Owned Subsidiary,

In the event of the occurrence of any of the events specified in the preceding sentence or in clause (A) or (B) of the preceding sentence, Definitive Notes delivered in exchange for any Global Note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of DTC (in accordance with its customary procedures).

The signature of the Trustee on a Note shall be conclusive evidence that such Note has been duly and validly authenticated and issued under this Indenture. A Note shall be dated the date of its authentication.

At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for delivery: (1) the Initial Notes for original issue on the Issue Date in an aggregate principal amount of $545,000,000 in the form of unrestricted Global Notes, (2) subject to the terms of this Indenture, Additional Notes for original issue in exchange for 2022 Notes in accordance with Section 3.3(b)(13) and (3) PIK Notes for original issue in accordance with Section 2.4 and paragraph 1 of the form of Note set forth in Exhibit A, in each case upon a written order of the Issuer signed by one Officer of the Issuer (the “Issuer Order”). Such Issuer Order shall specify whether the Notes will be in the form of Definitive Notes or Global Notes, the amount of the Notes to be authenticated, whether the Notes will be Initial Notes, Additional Notes or PIK Notes and the date on which such Notes are to be authenticated.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Issuer to authenticate the Notes. Any such instrument shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for delivery of notices and demands.

In case the Issuer or any Guarantor shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger, or into which the Issuer or any Guarantor shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee in accordance with Article IV, as applicable, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Notes executed in the name of the successor Person (in the case of Global Notes, subject to the applicable procedures of DTC) with such changes in phraseology and form as may be appropriate, but otherwise in

57

substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Issuer Order of the successor Person, shall authenticate and make available for delivery Notes as specified in such order for the purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section 2.2 in exchange or substitution for or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time outstanding for Notes authenticated and delivered in such new name.

SECTION 2.3 Registrar and Paying Agent. The Issuer shall maintain in the continental United States an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”), and an office or agency where Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Securities Register”). The Parent Guarantor or any of its Restricted Subsidiaries may act as Registrar or Paying Agent. The Issuer may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any co-registrar.

The Issuer shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee of the name and address of each such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.7. The Parent Guarantor or any of its wholly-owned Restricted Subsidiaries organized in the United States may act as Paying Agent, Registrar or transfer agent.

The Issuer initially appoints the Trustee as Registrar for the Notes at its corporate trust office in the United States, and as Paying Agent for the Notes at its corporate trust office in the United States. The Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of any appointment by a successor as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Issuer and the Trustee.

SECTION 2.4 Paying Agent to Hold Money in Trust. By no later than 11:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Issuer shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium, cash interest amount, and increase the principal amount of the Notes to pay PIK Interest or issue PIK Notes to pay PIK Interest pursuant to an Issuer Order delivered to the Trustee specifying the PIK Note amount to be issued or the increase in the amount of principal, as applicable, on the applicable interest payment date, when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Noteholders or the Trustee all money held by such Paying Agent for the payment of principal of, premium, if any,

58

or interest on the Notes (whether such assets have been distributed to it by the Issuer or other obligors on the Notes), shall notify the Trustee in writing of any default by the Issuer or any Guarantor in making any such payment and shall during the continuance of any default by the Issuer (or any other obligor upon the Notes) in the making of any payment in respect of the Notes, upon the written request of the Trustee, forthwith deliver to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Notes together with a full accounting thereof. If the Parent Guarantor or a Restricted 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 Issuer at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds or assets disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying Agent (if other than the Parent Guarantor or a Restricted Subsidiary) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Issuer or the Parent Guarantor, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.5 Noteholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Noteholders. If the Trustee is not the Registrar, each of the Issuer and the Parent Guarantor, on its own behalf and on behalf of each of the Subsidiary Guarantors, shall furnish or cause the Registrar to furnish to the Trustee, in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Noteholders.

SECTION 2.6 Transfer and Exchange.

(a) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by this Section 2.6. The Trustee shall promptly register any transfer or exchange that meets the requirements of this Section 2.6 by noting the same in the register maintained by the Trustee for the purpose, and no transfer or exchange shall be effective until it is registered in such register. The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section 2.6 and Sections 2.1(e) and (f), as applicable, and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and procedures of DTC. Subject to Section 2.6(h), the Trustee shall refuse to register any requested transfer or exchange that does not comply with this Section 2.6(a).

(b) [Reserved].

(c) [Reserved].

(d) Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes not bearing a Restricted Securities Legend, the Registrar shall deliver Notes that do not bear a Restricted Securities Legend. Upon the transfer, exchange or replacement of Notes bearing a Restricted Securities Legend, the Registrar shall deliver only Notes that bear a

59

Restricted Securities Legend unless (i) a Note is being transferred pursuant to an effective registration statement or (ii) there is delivered to the Issuer and the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer and the Registrar to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. Neither the Initial Notes nor any Additional Notes issued in exchange for 2022 Notes in accordance with Section 3.3(b)(13) shall be required to bear the Restricted Securities Legend.

(e) [Reserved].

(f) Retention of Written Communications. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.1 or this Section 2.6 in accordance with its customary procedures. The Issuer shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable prior written notice to the Registrar.

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

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

(ii) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Issuer may require the Holder to pay a sum sufficient to cover any transfer tax assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charges payable upon exchange or transfer pursuant to Sections 2.2, 2.12, 3.5, 3.9, 5.8 or 9.5).

(iii) The Issuer (and the Registrar) shall not be required to register the transfer of or exchange of any Note (A) for a period (1) of 15 days before a selection of Notes to be redeemed or (2) beginning 15 days before an interest payment date and ending on such interest payment date or (B) selected for redemption, except the unredeemed portion of any Note being redeemed in part.

(iv) Prior to the due presentation for registration of transfer of any Note, the Issuer, any Guarantor, the Trustee, the Paying Agent or the Registrar may deem and treat the person in whose name a Note is registered as the owner of such Note for the purpose of receiving payment of principal of, premium, if any, and (subject to paragraph 2 of the form of Note attached hereto as Exhibit A) interest on such Note and for all other purposes whatsoever, including without limitation the transfer or exchange of such Note, whether or not such Note is overdue, and none of the Issuer, any Guarantor, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

(v) [Reserved].

60

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

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

(i) Affiliate Holders. By accepting a beneficial interest in a Global Note, any Person that is an Affiliate of the Issuer agrees to give notice to the Issuer, the Trustee and the Registrar of the acquisition of such interest and its Affiliate status.

SECTION 2.7 [Reserved].

SECTION 2.8 [Reserved].

SECTION 2.9 [Reserved].

SECTION 2.10 Mutilated, Destroyed, Lost or Stolen Notes. If a mutilated Note is surrendered to the Registrar or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note if the Trustee’s requirements are met, such that the Noteholder (a) satisfies the Issuer or the Trustee that such Note has been lost, destroyed or wrongfully taken within a reasonable time after such Noteholder has notice of such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to receiving such notification, (b) makes such request to the Issuer or Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other customary requirements of the Trustee; provided, however, if after the delivery of such replacement Note, a protected purchaser of the Note for which such replacement

61

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

In case any such mutilated, destroyed, lost or wrongfully taken Note has become or is about to become due and payable, the Issuer in its discretion may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section 2.10, the Issuer may require that such Holder pay a sum sufficient to cover any transfer tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of counsel and of the Trustee) in connection therewith.

Subject to the proviso in the initial paragraph of this Section 2.10, every new Note issued pursuant to this Section 2.10 in lieu of any mutilated, destroyed, lost or wrongfully taken Note shall constitute an original additional contractual obligation of the Issuer, any Guarantor and any other obligor upon the Notes, whether or not the mutilated, destroyed, lost or wrongfully taken Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 2.10 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes.

SECTION 2.11 Outstanding Notes. Notes outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described in this Section 2.11 as not outstanding. A Note does not cease to be outstanding in the event the Issuer or an Affiliate of the Issuer holds the Note; provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the provisions of Section 12.6 shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Notes are present at a meeting of Holders of Notes for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Notes which a Trust Officer of the Trustee actually knows to be held by the Issuer or an Affiliate of the Issuer shall not be considered outstanding.

62

If a Note is replaced pursuant to Section 2.10 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement pursuant to Section 2.10.

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

SECTION 2.12 Temporary Notes. In the event that Definitive Notes are to be issued under the terms of this Indenture, until such Definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form, and shall carry all rights, of Definitive Notes but may have variations that the Issuer consider appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Definitive Notes. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at any office or agency maintained by the Issuer for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuer shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, one or more Definitive Notes representing an equal principal amount of Notes. Until so exchanged, the Holder of temporary Notes shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Notes.

SECTION 2.13 Cancellation. The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation and dispose of such Notes in accordance with its internal policies and customary procedures including delivery of a certificate describing such Notes disposed (subject to the record retention requirements of the Exchange Act). If the Issuer or any Guarantor acquires any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.13. The Issuer may not issue new Notes to replace Notes they have paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

At such time as all beneficial interests in a Global Note have either been exchanged for Definitive Notes, transferred, redeemed, repurchased or canceled, such Global Note shall be returned by DTC or the Securities Custodian to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Definitive Notes, transferred in exchange for an interest in another Global Note, redeemed, repurchased or canceled, the principal amount of Notes represented by such Global Note shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Securities Custodian, to reflect such reduction.

63

SECTION 2.14 Payment of Interest; Defaulted Interest. Interest on any Note which is payable, and is punctually paid or duly provided for, on any interest payment date shall be paid to the Person in whose name such Note (or one or more predecessor Notes) is registered at the close of business on the regular record date for such payment at the office or agency of the Issuer maintained for such purpose pursuant to Section 2.3.

Any interest on any Note which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the regular record date, and such defaulted interest and (to the extent lawful) interest on such defaulted interest in cash at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Issuer, at its election in each case, as provided in clause (a) or (b) below:

(a) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (the “Special Interest Payment Date”), and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Issuer shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest, which date shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Issuer shall promptly notify the Trustee of such Special Record Date, and shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 12.2, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

(b) The Issuer may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 2.14, each Note delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

64

SECTION 2.15 Computation of Interest.

(a) Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

(b) Solely for the purposes of the Interest Act (Canada), whenever any interest is calculated using a rate based on a year of 360 days, such rate determined pursuant to such calculation, when expressed as an annual rate, is equivalent to (i) the applicable rate based on a year of 360 days, multiplied by (ii) the actual number of days in the calendar year in which the period for such interest is payable (or compounded) ends, divided by (iii) 360. The principle of deemed reinvestment of interest shall not apply to any interest calculation under this Indenture; all interest payments to be made under this Indenture shall be paid without allowance or deduction for deemed reinvestment or otherwise, before and after demand, default and judgment. The rates of interest specified in this Indenture are intended to be nominal rates and not effective rates, and any interest calculated hereunder shall be calculated using the nominal rate method and not the effective rate method of calculation.

SECTION 2.16 CUSIP, Common Code and ISIN Numbers. The Issuer in issuing the Notes may use “CUSIP”, “Common Code” and “ISIN” numbers and, if so, the Trustee shall use “CUSIP”, “Common Code” and “ISIN” numbers in notices of redemption or purchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or purchase shall not be affected by any defect in or omission of such CUSIP, Common Code and ISIN numbers. The Issuer shall promptly notify the Trustee in writing of any change in the CUSIP, Common Code and ISIN numbers.

SECTION 2.17 Trustee, Paying Agent, Registrar Not Responsible for Depositary. None of the Trustee, any Paying Agent or the Registrar shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in any Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. The Trustee, any Paying Agent and the Registrar shall be entitled to deal with any depositary, and any nominee thereof, that is the Holder of any Global Note for all purposes of this Indenture relating to such Global Note (including the payment of principal, premium, if any, and interest, the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Note) as the sole Holder of such Global Note and shall have no obligations to the Beneficial Owners thereof. None of the Trustee, any Paying Agent or the Registrar shall have any responsibility or liability for any acts or omissions of any such depositary with respect to any Global Note, for the records of any depositary, including records in respect of beneficial ownership interests in respect of any Global Note, for any transactions between such depositary and any participant in such depositary or between or among any such depositary, any such participant or any holder or owner of a beneficial interest in any Global Note or for any transfers of beneficial interests in any Global Note.

65

SECTION 2.18 Payment of Additional Amounts.

(a) All payments made (or deemed to be made) to a holder of the Notes by a Guarantor pursuant to any Guarantee shall be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) (collectively, “Taxes”) imposed or levied by or on behalf of any Canadian government (or, with respect to any Guarantor (or any successor thereof) incorporated or organized outside the United States or Canada, the government of the country in which such Guarantor (or any successor thereof) is incorporated, organized or a tax resident) or political subdivision or territory or authority or agency therein or thereof having the power to tax (each a “Non-U.S. Taxing Authority”), unless the obligor thereon is required to withhold or deduct Taxes under any law or by the interpretation, application or administration thereof.

(b) If any such obligor is so required to withhold or deduct any amount of or on account of Taxes imposed by a Non-U.S. Taxing Authority from any payment made with respect to any Guarantee, such obligor shall pay, as additional interest, to each Holder or beneficial owner of the Notes that are outstanding on the date of the required payment such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by such Holder or beneficial owner (including the Additional Amounts) after such withholding or deduction (including withholdings and deductions on Additional Amounts) shall not be less than the amount such Holder or beneficial owner would have received if such Taxes had not been withheld or deducted; provided that no Additional Amounts shall be payable with respect to a payment made to a Holder or beneficial owner of the Notes (an “Excluded Holder”):

(1) which is subject to such Taxes by reason of the fact that it does not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) with the Parent Guarantor or any other Guarantor resident in Canada for tax purposes at the time of payment, if such payment is made by the Parent Guarantor or such other Canadian Guarantor;

(2) which is subject to such Taxes by reason of its being or having been connected with any Non-U.S. Taxing Authority other than by the mere holding or ownership, or deemed holding or ownership of the Notes or the receipt of payments thereunder or under any Guarantee or the enforcement of rights under the Notes, this Indenture or any Guarantee (as a matter of, for example, citizenship, nationality, residence, domicile, or existence of a business or permanent establishment, a dependent agent, a place of business or a place of management present or deemed present within the Non-U.S. Taxing Authority);

(3) where such Taxes are on account of any Tax imposed pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any fiscal or regulatory legislation, rules or practices adopted pursuant to an intergovernmental agreement between a non-U.S. jurisdiction and the United States, with respect to the forgoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code;

66

(4) which failed to duly and timely comply with a timely request of the Issuer or any Guarantor in writing to provide information, documents or other evidence concerning such Holder’s or beneficial owner’s nationality, residence, entitlement to treaty benefits or identity, if and to the extent that (i) such Holder and/or beneficial owner was legally able to comply with such request and (ii) due and timely compliance with such request is required by applicable law or administrative policy as a precondition to reduction or elimination of, and would have reduced or eliminated, any Taxes as to which Additional Amounts would have otherwise been payable to such Holder or beneficial owner but for this clause;

(5) which is a fiduciary or a partnership or not the sole beneficial owner of the relevant Note, if and to the extent that any beneficiary or settlor with respect to such fiduciary, any partner with respect to such partnership or any beneficial owner of such Note (as the case may be) would not have been entitled to receive Additional Amounts with respect to the payment in question had such beneficiary, settlor, partner or beneficial owner been the actual Holder of such Note;

(6) in respect of any estate, gift, inheritance, value added, excise, transfer, or similar tax; or

(7) any combination of the above clauses in this proviso.

For the avoidance of doubt, no Additional Amounts will be owed for Taxes imposed by the United States government or any political subdivision or territory or authority or agency therein or thereof having the power to tax.

(c) The applicable obligor on the Notes, this Indenture or any Guarantee, as the case may be, shall also be entitled to make any withholding or deduction required by a Non-U.S. Taxing Authority or other taxing authority and remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The applicable obligor on the Notes, this Indenture or any Guarantee, as the case may be, shall furnish to the Holders, within 30 days after the date the payment of any Taxes is due pursuant to applicable law, copies of tax receipts, if any, evidencing that such payment has been made by such obligor, as applicable.

(4) Indebtedness represented by (i) any Indebtedness (other than the Indebtedness of the type described in Section 3.2(b)(1), (2) and (4)) outstanding on the Issue Date and (ii) any Refinancing Indebtedness Incurred in respect of any Indebtedness of the type described in Section 3.2(b)(1), this Section 3.2(b)(4) or Section 3.2(b)(5) or (7);

71

(c) For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness Incurred pursuant to and in compliance with, this Section 3.2:

(1) in the event an item of that Indebtedness meets the criteria of more than one of the types of Indebtedness described in Section 3.2(b), the Parent Guarantor, in its sole discretion, will classify such item of Indebtedness on the date of Incurrence and, subject to Section 3.2(c)(2) below, may later classify, reclassify or redivide all or a portion of such item of Indebtedness, in any manner that complies with this Section 3.2;

(2) all Indebtedness outstanding on the date of this Indenture or subsequently Incurred under the Senior Secured Credit Agreements, the Senior Notes and the Notes shall be deemed Incurred on the Issue Date or the date of such Incurrence, respectively, under Section 3.2(b)(1);

(3) guarantees of, or obligations in respect of letters of credit supporting, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included;

(4) if obligations in respect of letters of credit are Incurred pursuant to a Credit Facility and are being treated as Incurred pursuant to Section 3.2(b)(1) and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included;

(5) the principal amount of any Disqualified Stock of the Parent Guarantor or a Restricted Subsidiary, or Preferred Stock of a Restricted Subsidiary, will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference thereof;

(6) Indebtedness permitted by this Section 3.2 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 3.2 permitting such Indebtedness; and

(7) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

Accrual of interest, accrual of dividends, the amortization of debt discount or the accretion of accreted value, the payment of interest in the form of additional Indebtedness, the payment of dividends in the form of additional Preferred Stock or Disqualified Stock and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of FASB ASC Topic No. 815, Derivatives and Hedging) will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 3.2.

72

The Parent Guarantor will not permit any of its Foreign Subsidiaries, Subsidiaries that are not Subsidiary Guarantors or Unrestricted Subsidiaries to Incur any Indebtedness (including to issue any Disqualified Stock) other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this Section 3.2, the Parent Guarantor shall be in Default of this Section 3.2).

For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 3.2, the maximum amount of Indebtedness that any Person may Incur pursuant to this Section 3.2 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rates of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

This Indenture shall not treat (1) unsecured Indebtedness as subordinated or junior to secured Indebtedness merely because it is unsecured or (2) senior Indebtedness as subordinated or junior to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral.

SECTION 3.3 Limitation on Restricted Payments.

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

(1) declare or pay any dividend or make any payment or distribution on or in respect of the Parent Guarantor’s or any Restricted Subsidiary’s Capital Stock (including any payment or distribution in connection with any merger or consolidation involving the Parent Guarantor or any of its Restricted Subsidiaries) except:

(2) purchase, repurchase, redeem, defease or otherwise acquire or retire for value any Capital Stock of the Parent Guarantor or any direct or indirect parent of the Parent Guarantor held by Persons other than the Parent Guarantor or a Restricted Subsidiary (other than in exchange for Capital Stock of the Parent Guarantor (other than Disqualified Stock));

(3) purchase, repurchase, redeem, defease or otherwise acquire or retire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Obligations or Guarantor Subordinated Obligations (other than (x) Indebtedness permitted under Section 3.2(b)(3) or (y) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Obligations or Guarantor Subordinated Obligations purchased in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, repurchase, redemption, defeasance or other acquisition or retirement for value); or

(4) make any Restricted Investment;

(any such dividend, distribution, purchase, redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in clauses (1) through (4) is referred to herein as a “Restricted Payment”).

(b) The provisions of Section 3.3(a) will not prohibit:

(1) any Restricted Payment made by exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of the Parent Guarantor (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of the Parent Guarantor or an employee stock ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from or guaranteed by the Parent Guarantor or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination) or a substantially concurrent cash capital contribution received by the Parent Guarantor from its shareholders; provided, however, that such Restricted Payment will be excluded from subsequent calculations of the amount of Restricted Payments;

(4) dividends paid or distributions made within 60 days after the date of declaration if at such date of declaration such dividend or distribution would have complied with this Section 3.3; provided, however, that such dividends and distributions will be included in subsequent calculations of the amount of Restricted Payments; and provided further, however, that for purposes of clarification, this clause (4) shall not include cash payments in lieu of the issuance of fractional shares included in clause (9) below;

(5) so long as no Default has occurred and is continuing, (a) the repurchase or other acquisition of Capital Stock (including options, warrants, equity appreciation rights or other rights to purchase or acquire Capital Stock) of the Parent Guarantor held by any existing or former employees, management or directors of the Parent Guarantor or any Restricted Subsidiary of the Parent Guarantor or their assigns, estates or heirs, in each case pursuant to the repurchase or other acquisition provisions under employee stock option or stock purchase plans or agreements or other agreements to compensate management, employees or directors, in each case approved by the Parent Guarantor’s Board of Directors; provided that such repurchases or other acquisitions pursuant to this subclause (a) during any calendar year will not exceed $2.0 million in the aggregate (with unused amounts in any calendar year being carried over to succeeding calendar years without limitation); provided further, that such amount in any calendar year may be increased by an amount not to exceed (A) the cash proceeds received by the Parent Guarantor from the sale of Capital Stock of the Parent Guarantor to members of management or directors of the Parent Guarantor and its Restricted Subsidiaries that occurs after the Issue Date, plus (B) the cash proceeds of key man life insurance policies received by the Parent Guarantor and its Restricted Subsidiaries after the Issue Date, less (C) the amount of any Restricted Payments made pursuant to clauses (A) and (B) of this clause (5)(a); provided further, however, that the amount of any such repurchase or other acquisition under this subclause (a) will be excluded in subsequent calculations of the amount of Restricted Payments; and (b) loans or advances to employees or directors of the Parent Guarantor or any Subsidiary of the Parent Guarantor, in each case as permitted by Section 402 of the Sarbanes-Oxley Act of 2002, the proceeds of which are used to

77

The Parent Guarantor shall not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the last sentence of the definition of “Unrestricted Subsidiary.” For purpose of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Parent Guarantor and its Restricted Subsidiaries (except to the extent such Investments are repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investment.” Such designation will be permitted only if a Restricted Payment in such amount would be permitted at such time pursuant to the definition of “Permitted Investments,” and if such Subsidiary otherwise meets the definition of “Unrestricted Subsidiary.”

SECTION 3.4 Limitation on Restrictions on Distributions from Restricted Subsidiaries.

(a) The Parent Guarantor will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any such Restricted Subsidiary that is not the Issuer or a Subsidiary Guarantor to:

(1) pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Parent Guarantor or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock);

(2) make any loans or advances to the Parent Guarantor or any Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Parent Guarantor or any Restricted Subsidiary to other Indebtedness Incurred by the Parent Guarantor or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

(3) sell, lease or transfer any of its property or assets to the Parent Guarantor or any Restricted Subsidiary.

SECTION 3.5 Limitation on Sales of Assets and Subsidiary Stock.

(a) The Parent Guarantor will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

(1) the Parent Guarantor or any of its Restricted Subsidiaries receives consideration at the time of such Asset Disposition at least equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Disposition) of the Capital Stock or other assets subject to such Asset Disposition;

(2) except in the case of an Asset Swap, at least 75% of the consideration (determined on the date of contractually agreeing to such Asset Disposition) received by the Parent Guarantor or any of its Restricted Subsidiaries from such Asset Disposition and all other Asset Dispositions since the Issue Date, on a cumulative basis, is in the form of cash or Cash Equivalents, or any combination thereof; provided that any consideration other than cash or Cash Equivalents received by the Parent Guarantor or any of its Restricted Subsidiaries from such Asset Disposition shall only be permitted if it consists solely of the right to receive earnout payments, production payments, overrides or drilling participation arrangements or in seller notes (or a similar form of customary seller financing);

81

(3) except as provided in Section 3.5(b), an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied, within 365 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, by the Parent Guarantor or such Restricted Subsidiary, as the case may be:

(A) to prepay, repay, redeem or purchase Indebtedness under the Senior Secured Credit Agreements;

(B) to prepay, repay, redeem or purchase Notes by, at its option, (x) redeeming Notes as provided under paragraph 5 of the form of Note set forth in Exhibit A, (y) purchasing Notes through open-market purchases or in privately negotiated transactions at market prices (which shall be at or above par) and/or (z) making an offer (in accordance with the provisions set forth in this Section 3.5 for an Asset Disposition Offer) to all Holders to purchase their Notes (which offer shall be deemed to be an Asset Disposition Offer for purposes hereof); or

(C) to invest in Additional Assets; provided that without limitation to the provisions described in Section 11.3, to the extent any Additional Assets received by the Company or such Restricted Subsidiary in such Asset Sale consists of assets of a type that would constitute Collateral under the Note Security Documents, such Additional Assets, including Capital Stock of any Person that becomes a Restricted Subsidiary as a result of such transaction, are added to the Collateral within the time periods set forth in Section 11.3 or the applicable Note Security Documents; and

(4) without limitation to the provisions described in Section 11.3, to the extent any consideration received by the Company or such Restricted Subsidiary in such Asset Sale consists of assets of a type that would constitute Collateral under the Note Security Documents, such assets, including assets of any Person that becomes a Guarantor as a result of such transaction, are added to the Collateral within the time periods set forth in Section 11.3 or the applicable Note Security Documents;

provided that pending the final application of any such Net Available Cash in accordance with clauses (A), (B) or (C) above, the Parent Guarantor and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by this Indenture. The requirement of clause (C) above 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 Parent Guarantor or its Restricted Subsidiary within the specified time period and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

(b) Any Net Available Cash from Asset Dispositions that is not applied or invested as provided in Section 3.5(a)(3) will be deemed to constitute “Excess Proceeds.” Not later than the 366th day from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, if the aggregate amount of Excess Proceeds exceeds $5.0 million, the Issuer will be required to make an offer (“Asset Disposition Offer”) to all Holders (with a copy to the

82

Trustee) to purchase the maximum principal amount of the Notes that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the procedures set forth in this Section 3.5 in integral multiples of $1.00 in excess of $2,000 (or in excess of $1.00 after a PIK Payment), provided that the unpurchased portion of each Note must be equal to a minimum principal amount of $2,000 or an integral multiple of $1.00 in excess of $2,000 (or in excess of $1.00 after a PIK Payment). If the aggregate principal amount of the Notes surrendered by Holders thereof exceeds the amount of Excess Proceeds, the Issuer shall select the Notes to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes. To the extent that the aggregate principal amount of the Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Parent Guarantor and its Restricted Subsidiaries may use any remaining Excess Proceeds for general corporate purposes, subject to the other covenants contained in this Indenture. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

(c) The Asset Disposition Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five Business Days after the termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the Issuer will purchase the principal amount of the Notes required to be purchased pursuant to this Section 3.5 (the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered and not properly withdrawn, all Notes validly tendered and not properly withdrawn in response to the Asset Disposition Offer.

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

(e) On or before the Asset Disposition Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Notes or portions of Notes so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Notes so validly tendered and not properly withdrawn, in each case in integral multiples of $1.00 in excess of $2,000 (or in excess of $1.00 after a PIK Payment), provided that the unpurchased portion of each Note must be equal to a minimum principal amount of $2,000 or an integral multiple of $1.00 in excess of $2,000 (or minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof after a PIK Payment). The Issuer will deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 3.5. The Issuer or the paying agent, as the case may be, will promptly (but in any case not later than five Business Days after the termination of the Asset Disposition Offer Period) mail or deliver to each tendering Holder of the Notes an amount equal to the purchase

83

price of the Notes so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon delivery of an Issuer Order and Officers’ Certificate from the Issuer, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1.00 in excess of $2,000 (or minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof after a PIK Payment). Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date.

(f) The Issuer will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws or regulations in connection with the repurchase of the Notes pursuant to an Asset Disposition Offer. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 3.5, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of its compliance with such securities laws or regulations.

(g) For the purposes of Section 3.5(a)(2), the following will be deemed to be cash:

(1) the assumption by the transferee of Indebtedness of the Parent Guarantor (other than Subordinated Obligations, Guarantor Subordinated Obligations or Disqualified Stock of the Parent Guarantor) or Indebtedness of a Restricted Subsidiary (other than Subordinated Obligations, Guarantor Subordinated Obligations of any Subsidiary Guarantor or Disqualified Stock of any Restricted Subsidiary) and the release of the Parent Guarantor or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition (in which case the Parent Guarantor will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with Section 3.5(a)(3);

(2) with respect to any Asset Disposition of Oil and Gas Properties by the Parent Guarantor or any of its Restricted Subsidiaries in which the Parent Guarantor or such Restricted Subsidiary still retains an interest, any agreement by the transferee (or any Affiliate thereof) to pay all or a portion of the costs and expenses related to the exploration, development, completion or production of such properties and activities related thereto; and

(3) securities, notes or other obligations received by the Parent Guarantor or any Restricted Subsidiary from the transferee that are converted by the Parent Guarantor or such Restricted Subsidiary into cash within 180 days after receipt thereof.

84

(h) The Parent Guarantor will not, and will not permit any Restricted Subsidiary to, engage in any Asset Swaps, unless:

(1) at the time of entering into such Asset Swap and immediately after giving effect to such Asset Swap, no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof; and

(2) in the event such Asset Swap involves the transfer by the Parent Guarantor or any Restricted Subsidiary of assets having an aggregate Fair Market Value in excess of $10.0 million, the terms of such Asset Swap have been approved by a majority of the members of the Board of Directors of the Parent Guarantor.

(i) Other than as specifically provided in this Section 3.5, any purchase pursuant to this Section 3.5 shall be made pursuant to the applicable provisions of Article V.

SECTION 3.6 Limitation on Liens. The Parent Guarantor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist any Lien other than Permitted Liens upon any of its property or assets (including Capital Stock of Restricted Subsidiaries), including any income or profits therefrom, whether owned on the date of this Indenture or acquired after that date.

SECTION 3.7 Stay, Extension and Usury Laws. The Parent Guarantor and each of its Restricted Subsidiaries covenant (to the extent that they may lawfully do so) that they shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Parent Guarantor and each of its Restricted Subsidiaries (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant that they shall not, by resort to any such law, 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 has been enacted.

SECTION 3.8 Limitation on Affiliate Transactions.

(a) The Parent Guarantor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into, make, amend or conduct any transaction (including making a payment to, the purchase, sale, lease or exchange of any property or the rendering of any service), contract, agreement or understanding with or for the benefit of any Affiliate of the Parent Guarantor (an “Affiliate Transaction”) unless:

(1) the terms of such Affiliate Transaction are not materially less favorable to the Parent Guarantor or such Restricted Subsidiary, as the case may be, than those that could reasonably be expected to be obtained in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate; and

(2) either:

(A) if such Affiliate Transaction involves an aggregate consideration in excess of $5.0 million but not greater than $10.0 million, the Parent Guarantor delivers to the Trustee an Officers’ Certificate certifying that such Affiliate Transaction satisfies the criteria in clause (1) above; or

85

(B) if such Affiliate Transaction involves an aggregate consideration in excess of $10.0 million, the Parent Guarantor delivers to the Trustee a Board Resolution adopted by a majority of the members of the Board of Directors of the Parent Guarantor having no personal stake in such transaction approving the terms of such transaction and set forth in an Officers’ Certificate certifying that such Affiliate Transaction satisfies the criteria in clause (1) above.

(a) Whether or not the Parent Guarantor is subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, to the extent not prohibited by the Exchange Act, the Parent Guarantor will file with the SEC, and deliver to the Trustee and make available to the Holders without cost to any Holder, the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange

90

Act and applicable to a U.S. corporation within the time periods specified therein with respect to a non-accelerated filer. In the event that the Parent Guarantor is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Parent Guarantor will nevertheless deliver such Exchange Act information to the Trustee and make available to the Holders without cost to any Holder as if the Parent Guarantor were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act and applicable to a U.S. corporation within the time periods specified therein with respect to a non-accelerated filer.

(b) If the Parent Guarantor has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the financial information required will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, or in any accompanying Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Parent Guarantor and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries.

(c) Any direct or indirect parent entity of the Parent Guarantor may satisfy the obligations of the Parent Guarantor set forth in this Section 3.10 by providing the requisite financial and other information of such parent entity instead of the Parent Guarantor so long as (i) the Parent Guarantor is a Wholly-Owned Subsidiary of such parent entity and (ii) such parent entity does not conduct any business other than the holding of Equity Interests of the Parent Guarantor, does not have any material liabilities other than liabilities of the Parent Guarantor, does not own any material assets other than the Equity Interests of the Parent Guarantor and does not generate or derive any material revenues other than the revenues of the Parent Guarantor; provided that to the extent such parent entity holds assets (other than its direct or indirect interest in the Parent Guarantor) that exceeds the lesser of (x) 0.5% of the total assets of such parent entity and (y) 0.5% of the total revenue for the preceding fiscal year of such parent entity, then such information related to such parent entity shall be accompanied by consolidating information, which may be unaudited, that explains in reasonable detail the differences between the information of such parent entity, on the one hand, and the information relating to the Parent Guarantor and its Subsidiaries on a stand-alone basis, on the other hand.

(d) The availability of the foregoing materials on the SEC’s website or on the Parent Guarantor’s (or its parent entity’s) website shall be deemed to satisfy the foregoing delivery obligations to the Holders.

(e) For so long as any Notes remain outstanding and constitute “restricted securities” under Rule 144, if the Parent Guarantor is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Parent Guarantor will furnish to the Holders, and to securities analysts and bona fide prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(f) In addition, no later than five Business Days after the date the annual and quarterly financial information for the prior fiscal period have been filed or furnished pursuant to Section 3.10(a) (or customary earnings releases in respect thereof), the Parent Guarantor (or its parent entity) shall also hold live quarterly conference calls (which may be the same call held by the Parent Guarantor (or its parent entity) for its public equity holders).

91

(g) The Trustee shall have no obligation to determine if and when the reports, information and documents of the Parent Guarantor are filed with the SEC via the EDGAR system and available on the SEC’s EDGAR website or available on the Issuer’s website.

(h) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on Officers’ Certificates). The Trustee is under no duty to examine such reports, information or documents to ensure compliance with the provision of this Indenture or to ascertain the correctness or otherwise of the information or the statements contained therein.

SECTION 3.11 Future Subsidiary Guarantors.

(a) The Parent Guarantor will cause (i) each of its Wholly-Owned Subsidiaries (other than a Foreign Subsidiary formed in connection with a Redomestication Transaction) formed or acquired after the Issue Date and (ii) any other Domestic Subsidiary (other than the Issuer) that is not already a Subsidiary Guarantor that guarantees any of the Parent Guarantor’s or the Issuer’s Indebtedness or any Indebtedness of a Subsidiary Guarantor, in each case to execute and deliver to the Trustee within 30 days a supplemental indenture (in substantially the form specified in Exhibit B to this Indenture) pursuant to which such Subsidiary will unconditionally guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest on the Notes on a senior basis; provided that any Restricted Subsidiary that constitutes an Immaterial Subsidiary need not become a Subsidiary Guarantor until such time as it ceases to be an Immaterial Subsidiary.

(b) Each Person that becomes a Subsidiary Guarantor after the Issue Date shall also become a party to the applicable Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement, if applicable, and shall as promptly as practicable execute and deliver such security instruments, financing statements, mortgages, deeds of trust (in substantially the same form as those executed and delivered with respect to the Collateral on the Issue Date or on the date first delivered in the case of any such documents to be delivered after the Issue Date) as may be necessary to vest in the Collateral Agent a perfected second-priority security interest (subject to Permitted Liens) in properties and assets that constitute Collateral as security for the Notes or the Guarantees and as may be necessary to have such property or asset added to the applicable Collateral as required under the Note Security Documents and this Indenture, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such properties and assets to the same extent and with the same force and effect.

SECTION 3.12 Maintenance of Office or Agency. The Issuer shall maintain an office or agency where the Notes may be presented or surrendered for payment, where, if applicable, the Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be made. The corporate trust office of the Trustee indicated in Section 2.3 shall be such office or agency of the Issuer, unless the Issuer shall designate and maintain some other office or agency for one or

92

more of such purposes. The Issuer shall give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the corporate trust office of the Trustee indicated in Section 12.2, and the Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. Notwithstanding the foregoing, no service of legal process may be made on the Issuer at any office of the Trustee.

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such other office or agency.

SECTION 3.13 Corporate Existence. Except as otherwise provided in Article IV, the Parent Guarantor shall, and shall cause each of its Restricted Subsidiaries to, do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory), licenses and franchises; provided, however, that the Parent Guarantor and its Restricted Subsidiaries shall not be required to preserve any such right, license or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Parent Guarantor.

SECTION 3.14 Payment of Taxes. The Parent Guarantor shall, and shall cause each of its Restricted Subsidiaries to, pay or discharge or cause to be paid or discharged, before the same shall become delinquent, all material taxes, assessments and governmental charges levied or imposed upon the Parent Guarantor or any Subsidiary or upon the income, profits or property of the Parent Guarantor or any Subsidiary; provided, however, that the Parent Guarantor and its Restricted Subsidiaries shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment or charge the amount, applicability or validity of which is being contested in good faith by appropriate proceedings.

SECTION 3.15 Compliance Certificate. The Issuer shall deliver to the Trustee within 120 days after the end of each fiscal year of the Issuer ending after the Issue Date a statement (which need not be an Officers’ Certificate) signed by the principal executive officer, the principal accounting officer or the principal financial officer of the Issuer, stating that a review of the activities of the Issuer and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuer and each of its Restricted Subsidiaries has performed their respective obligations under this Indenture, and further stating whether or not the signers know of any Default or Event of Default that occurred during such period. If they do, the certificate shall describe such Default or Event of Default, its status and what action the Issuer is taking or proposes to take with respect thereto.

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

93

SECTION 3.17 Statement by Officers as to Default. The Issuer shall, so long as any Note is outstanding, deliver to the Trustee within 10 Business Days after the occurrence of a Default, a written notice setting forth the details of such Default, or Events of Default, and what action the Issuer is taking or proposing to take with respect thereto.

SECTION 3.18 Covenant Termination.

(a) From and after the occurrence of an Investment Grade Rating Event, the Parent Guarantor and its Restricted Subsidiaries will no longer be subject to the provisions of this Indenture described above in Sections 3.2, 3.3, 3.4, 3.5, 3.8 and Section 4.1(a)(3) hereof (collectively, the “Eliminated Covenants”).

(b) After the Eliminated Covenants have been terminated, the Parent Guarantor may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the second sentence of the definition of “Unrestricted Subsidiary.” After the Eliminated Covenants have been terminated, the Parent Guarantor and its Restricted Subsidiaries shall be entitled to incur Liens permitted under Section 3.6 (including, without limitation, Permitted Liens). To the extent Section 3.6 and any Permitted Liens refer to one or more Eliminated Covenants, such Section 3.6 or definition shall be interpreted as though such applicable Eliminated Covenant(s) continued to be applicable following such termination (but solely for purposes of Section 3.6 and the “Permitted Liens” definition and for no other section of this Indenture).

(c) On the date of the occurrence of an Investment Grade Rating Event, the Issuer shall deliver an Officers’ Certificate to the Trustee, specifying (i) that a termination of the foregoing covenants under this Section 3.18 has occurred and (ii) the date of the commencement of any termination of the foregoing covenants under this Section 3.18. The Trustee shall not have any duty to monitor the ratings of the Notes or whether or not an Investment Grade Rating Event or the termination of the foregoing covenants has occurred, nor any duty to notify the Noteholders of any of the foregoing.

SECTION 3.19 Limitation on Layering. The Parent Guarantor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, or suffer to exist any Lien that is (a) senior to the Liens on the Collateral securing the Notes and junior to any other Lien or (b) junior to the Liens on the Collateral securing the Notes (other than Liens securing Permitted Third Lien Indebtedness incurred under Section 3.2(b)(10) and clause (16) of the definition of “Permitted Liens”).

SECTION 3.20 Subsidiaries. The Parent Guarantor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, sell, assign or otherwise dispose of any Equity Interests in the Issuer or any Restricted Subsidiary except (a) to the Issuer or another Restricted Subsidiary or (b) in compliance with Section 3.5. None of the Parent Guarantor, the Issuer nor any Restricted Subsidiary will have any Foreign Subsidiaries, other than Foreign Subsidiary formed in connection with a Redomestication Transaction. Parent Guarantor and the Issuer will not permit any Equity Interests of any Restricted Subsidiary to be directly owned by any Person other than the Issuer or another Restricted Subsidiary. Parent Guarantor shall not permit any Subsidiary that is not owned by the Issuer to own any Oil and Gas Property.

94

SECTION 3.21 Nature of Business; International Operations. The Parent Guarantor will not, and will not permit any of its Restricted Subsidiaries to, undertake or allow any material change in the character of its business as a company engaged in the Oil and Gas Business. From and after the date hereof, Parent Guarantor, the Issuer and the Restricted Subsidiaries will not acquire or commit to acquire any Oil and Gas Properties not located within the geographical boundaries of the United States of America. Parent Guarantor shall not directly own any interest in any Oil and Gas Property. Any Oil and Gas Properties of the Issuer or any of its subsidiaries will at all times be owned by the Issuer or a Subsidiary Guarantor that is a Restricted Subsidiary.

ARTICLE IV

SUCCESSOR COMPANY

SECTION 4.1 Merger and Consolidation.

(a) Neither the Parent Guarantor nor the Issuer will consolidate with or merge with or into or amalgamate or wind up into (whether or not it is the surviving Person), or sell, lease, transfer, convey or otherwise dispose of all or substantially all its assets in one or more related transactions to, any Person, unless:

(1) (A) the resulting, surviving or transferee Person (the “Successor Company”) will be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia; provided that in the case where the Successor Company of the Issuer is not a corporation, a co-issuer of the Notes is a corporation; and (B) the Successor Company (if not the Parent Guarantor or the Issuer, as the case may be) will expressly assume, by supplemental indenture, joinder or other documents or instruments, executed and delivered to the Trustee, all the obligations of the Parent Guarantor or the Issuer, as the case may be, under this Indenture, the Notes, the Priority Lien Security Documents, the Note Security Documents, the Junior Lien Security Documents, the Intercreditor Agreement, the Third Lien Intercreditor Agreement and the relevant Guarantee, as applicable, and the Successor Company shall cause such amendments, supplements or other instruments to be executed, filed and recorded in such jurisdictions as may be required by applicable law to preserve and protect the Lien on the Collateral owned by or transferred to such Successor Company, together with such financing statements or comparable documents as may be required to perfect any security interests in such Collateral which may be perfected by the filing of a financing statement or a similar document under the Uniform Commercial Code or other similar statute or regulation of the relevant states or jurisdictions; provided further that, notwithstanding the foregoing, the Parent Guarantor may consummate a Redomestication Transaction if all other conditions of this Section 4.1(a) are satisfied;

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

95

(3) immediately after giving effect to such transaction on a pro forma basis and any related financing transactions as if the same had occurred at the beginning of the applicable four quarter period, the Consolidated Coverage Ratio of the Parent Guarantor is equal to or greater than the Consolidated Coverage Ratio of the Parent Guarantor immediately before such transaction;

(4) if the Successor Company of the Issuer is not the Issuer, each Guarantor (unless it is the other party to the transactions, in which case clause (1) shall apply) shall have by supplemental indenture confirmed that its Guarantee shall apply to the Successor Company’s obligations in respect of this Indenture and the Notes and that its Guarantee shall continue to be in effect; and

(5) the Parent Guarantor or the Issuer, as the case may be, shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such transaction and such supplemental indenture (if any) comply with this Indenture; and

(6) any Collateral owned by or transferred to the Successor Company formed by or surviving any such consolidation or merger or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made continues to constitute Collateral under the Indenture and the Note Security Documents, subject to the Liens on the Collateral securing Priority Obligations, except as permitted by the Indenture or the Note Security Documents.

For purposes of this Section 4.1, the sale, lease, transfer, conveyance or other disposition of all or substantially all of the assets of one or more Subsidiaries of the Parent Guarantor or the Issuer, as the case may be, which assets, if held by the Parent Guarantor or the Issuer instead of such Subsidiaries, would constitute all or substantially all of the assets of the Parent Guarantor or the Issuer, as applicable, on a consolidated basis, shall be deemed to be the disposition of all or substantially all of the assets of the Parent Guarantor or the Issuer, as applicable.

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Parent Guarantor or the Issuer, as the case may be, under this Indenture and the other Notes Documents; and its predecessor, except in the case of a lease of all or substantially all its assets, will be released from all obligations under this Indenture, the other Notes Documents, the Notes or the relevant Guarantee, as applicable.

Notwithstanding Section 4.1(a)(3), (x) any Restricted Subsidiary may consolidate with, merge with or into, amalgamate or wind up into, or dispose of all or part of its assets to, the Parent Guarantor, and the Parent Guarantor may consolidate with, merge into, amalgamate or wind up into, or dispose of all or part of its assets to, the Issuer or a Subsidiary Guarantor and (y) the Parent Guarantor and the Issuer may merge with or into an Affiliate incorporated solely for the purpose of reorganizing the Parent Guarantor or the Issuer, as the case may be, in a State of the United States or the District of Columbia or other jurisdiction; provided that, in the case of a Restricted Subsidiary that consolidates with, merges with or into, amalgamates or winds up into or disposes of all or part of its properties and assets to the Parent Guarantor or the Issuer, the Parent Guarantor or the Issuer, as the case may be, will not be required to comply with the preceding Section 4.1(a)(5).

96

(b) In addition, the Parent Guarantor will not permit any Subsidiary Guarantor to consolidate with, merge with or into, amalgamate or wind up into, and will not permit the disposition of all or substantially all of the assets of any Subsidiary Guarantor to, any Person (other than the Parent Guarantor, the Issuer or another Subsidiary Guarantor) unless:

(1) (i) the resulting, surviving or transferee Person will be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any state of the United States or the District of Columbia and such Person (if not such Subsidiary Guarantor) will expressly assume, by supplemental indenture, executed and delivered to the Trustee, all the obligations of such Subsidiary Guarantor under this Indenture, the Notes, the Priority Lien Security Documents, the Note Security Documents, the Junior Lien Security Documents, the Intercreditor Agreement, the Third Lien Intercreditor Agreement and the relevant Guarantee, as applicable, and the surviving Person shall cause such amendments, supplements or other instruments to be executed, filed and recorded in such jurisdictions as may be required by applicable law to preserve and protect the Lien on the Collateral owned by or transferred to such surviving Person, together with such financing statements or comparable documents as may be required to perfect any security interests in such Collateral which may be perfected by the filing of a financing statement or a similar document under the Uniform Commercial Code or other similar statute or regulation of the relevant states or jurisdictions; and (ii) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the resulting, surviving or transferee Person or any Restricted Subsidiary as a result of such transaction as having been Incurred by such Person or such Restricted Subsidiary at the time of such transaction), no Default shall have occurred and be continuing; or

(2) the transaction results in the release of the Subsidiary Guarantor from its obligations under this Indenture and its Guarantee after and in compliance with the provisions of Section 10.2 and

(3) the Parent Guarantor will have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such transaction and such supplemental indenture (if any) comply with this Indenture.

ARTICLE V

REDEMPTION OF NOTES

SECTION 5.1 Redemption. The Notes may be redeemed (a) as a whole or from time to time in part, subject to the conditions and at the redemption prices specified in paragraph 5 of the form of Note set forth in Exhibit A hereto, which is hereby incorporated by reference and made a part of this Indenture, or (b) as a whole, and not less than as a whole, subject to the conditions and at the redemption price specified in Section 3.9(i) or Section 5.9, as applicable, in each case together with accrued and unpaid interest to the Redemption Date.

97

SECTION 5.2 Applicability of Article. Redemption of Notes at the election of the Issuer, as permitted by any provision of this Indenture, shall be made in accordance with such provision and this Article V.

SECTION 5.3 Election to Redeem; Notice to Trustee. The election of the Issuer to redeem any Notes pursuant to Section 5.1 shall be evidenced by an Officers’ Certificate of the Issuer. In case of any redemption at the election of the Issuer, the Issuer shall, not later than five Business Days prior to giving notice of any redemption pursuant to Section 5.5 (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Notes to be redeemed and, in the case of any redemption of less than all Notes, shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 5.4. Any such notice may be cancelled at any time prior to notice of such redemption being sent to any Holder and shall thereby be void and of no effect.

SECTION 5.4 Selection by Trustee of Notes to Be Redeemed. If less than all Notes are to be redeemed at any time pursuant to an optional redemption, the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Notes not previously called for redemption, in compliance with the requirements, as set forth in an Officers’ Certificate delivered by the Issuer to the Trustee, of the principal national securities exchange, if any, on which such Notes are listed, or, if such Notes are not so listed, then on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate (or, in the case of Global Notes, the Trustee will select Notes for redemption based on such method as DTC may prescribe); provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less than $2,000 (or $1.00 after a PIK Payment).

The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the method it has chosen for the selection of Notes and the principal amount thereof to be redeemed.

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

SECTION 5.5 Notice of Redemption.

(a) Notice of redemption shall be given in the manner provided for in Section 12.2, not less than 15 nor more than 60 days prior to the Redemption Date, to each Holder of Notes to be redeemed, except that that redemption notices may be sent more than 60 days prior to a Redemption Date if the notice is issued in connection with a legal defeasance or covenant defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article VIII or except as set forth in the penultimate sentence of Section 5.5(b). At the Issuer’s request, the Trustee shall give notice of redemption in the Issuer’s name and at the Issuer’s expense; provided, however, that the Issuer shall deliver to the Trustee, at least five Business Days prior to the giving of such notice (unless a shorter period shall be satisfactory to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice at the Issuer’s expense and setting forth the information to be stated in such notice as provided in the following items.

98

All notices of redemption shall state:

(1) the Redemption Date,

(2) the redemption price, if then determinable, and otherwise the method for its determination and the amount of accrued interest to the Redemption Date payable as provided in Section 5.7, if any,

(3) if less than all outstanding Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption,

(4) in case any Note is to be redeemed in part only, the notice which relates to such Note shall state that on and after the Redemption Date, upon surrender of such Note, the Holder will receive, without charge, a new Note or Notes of authorized denominations for the principal amount thereof remaining unredeemed,

(5) that on the Redemption Date, the redemption price (and accrued interest, if any, to the Redemption Date payable as provided in Section 5.7) will become due and payable upon each such Note, or the portion thereof, to be redeemed, and, unless the Issuer defaults in making the redemption payment, that interest on Notes called for redemption (or the portion thereof) will cease to accrue on and after said date,

(6) the place or places where such Notes are to be surrendered for payment of the redemption price and accrued interest, if any,

(7) the name and address of the Paying Agent,

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

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

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

(11) if in connection with any conditional notice of redemption pursuant to the Issuer’s right to redeem all of the Notes upon a Change of Control Triggering Event, and in compliance with Section 5.5(b), that such redemption is conditional upon such Change of Control Triggering Event occurring.

99

(b) Any redemption or notice of redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent and, in the case of a redemption with the Net Cash Proceeds of an Equity Offering, be given prior to the completion of the related Equity Offering. If such redemption is subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuer’s discretion, the Redemption Date may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission (subject to the applicable procedures of DTC)) as any or all such conditions shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption or by the Redemption Date as so delayed, or such notice may be rescinded at any time in the Issuer’s discretion if the Issuer reasonably believes that any or all of such conditions will not be satisfied. In addition, the Issuer may provide in such notice that payment of the redemption and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

SECTION 5.6 Deposit of Redemption Price. Prior to 11:00 a.m., New York City time, on any Redemption Date, the Issuer shall deposit with the Trustee or with a Paying Agent (or, if the Issuer or any of the Issuer’s Restricted Subsidiaries is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.4) an amount of money sufficient (as determined by the Issuer) to pay the redemption price of and accrued and unpaid cash interest together with an amount of cash equal to all accrued and unpaid PIK Interest on, all Notes which are to be redeemed on that date (including any PIK Notes or any increased principal amount of Notes in connection with a PIK Payment), other than Notes or portions of Notes called for redemption that are beneficially owned by the Issuer and have been delivered by the Issuer to the Trustee for cancellation.

SECTION 5.7 Notes Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Notes or portions of Notes so to be redeemed without a condition precedent shall, on the Redemption Date, become due and payable at the redemption price therein specified (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Issuer shall default in the payment of the redemption price and accrued interest) such Notes shall cease to bear interest and the only right of the Holders thereof will be to receive payment of the redemption price and, subject to the next sentence, unpaid interest on such Notes to the Redemption Date. Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Issuer at the redemption price, together with accrued interest, if any, to, but not including, the Redemption Date, provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holder of such Note, or one or more predecessor Notes, registered as such as of the relevant record date.

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the unpaid principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Notes.

SECTION 5.8 Notes Redeemed in Part. Any Note which is to be redeemed only in part (pursuant to the provisions of this Article V) shall be surrendered at the office or agency of the Issuer maintained for such purpose pursuant to Section 3.12 (with, if the Issuer or the Trustee

100

so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Issuer shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Note at the expense of the Issuer, a new Note or Notes, of any authorized denomination as requested by such Holder, in an aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered; provided, that each such new Note will be in a principal amount of $2,000 or integral multiple of $1.00 in excess thereof (or minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof after a PIK Payment).

SECTION 5.9 Tax Redemption.

(a) The Issuer may, at its option, upon providing not less than 30 days’ notice to the Trustee and the Holders, redeem, in whole but not in part, the outstanding Notes at a redemption price of 100% of the principal amount thereof plus accrued and unpaid interest to the date of redemption if any Guarantor has become or would become obligated to pay any Additional Amounts or any Reimbursement Payments in respect of any Guarantee as a result of:

(1) any change in or amendment to the laws (or regulations promulgated thereunder) of any Non-U.S. Taxing Authority, or

(2) any change in or amendment to any official position regarding the application, administration or interpretation of such laws, regulations, rulings, technical interpretations, income tax folios, interpretation bulletins, information circulars or equivalent documents issued by a Non-U.S. Taxing Authority (including a holding, judgment or order by a court of competent jurisdiction), which change or amendment is announced and becomes effective after the Issue Date (without regard to whether the Issuer or any Guarantor is or has been making any payments under the Notes prior to, at or after the time such change or amendment is announced or effective).

(b) It shall be a condition to the Issuer’s right to redeem the Notes pursuant to the provisions of Section 5.9(a) that, prior to giving any notice of redemption of the Notes, the Issuer shall have delivered to the Trustee (i) an Officers’ Certificate stating that the Issuer has determined in its reasonable judgment that the obligations to pay such Additional Amounts or Reimbursement Payments cannot be avoided by such Guarantor taking reasonable measures available to it and (ii) an Opinion of Counsel that such Guarantor has or will become obligated to pay Additional Amounts or Reimbursement Payments as a result of an amendment or change described in Section 5.9(a).

(c) No such notice of redemption may be given more than 60 days before or more than 180 days after any Guarantor first becomes liable (or, if later, the earlier of the date on which such Guarantor first becomes aware of its liability or the date on which it reasonably should have become aware of its liability) to pay any Additional Amounts or Reimbursement Payments as a result of a change or amendment described in Section 5.9(a).

SECTION 6.1 Events of Default.

(a) An “Event of Default” wherever used herein, means any one of the following events in relation to the Notes (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) default in any payment of interest on any Note when due, continued for 30 days;

(3) failure by the Issuer or any Guarantor to comply with its obligations under Article IV;

(4) failure by the Parent Guarantor or any Restricted Subsidiary to comply for 30 days (or 180 days in the case of a Reporting Failure) after notice has been given, by registered or certified mail, to the Parent Guarantor by the Trustee or to the Parent Guarantor and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder with Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.8, 3.9, 3.10, 3.11, 3.19, 3.20 and 3.21 (in each case, other than a failure to purchase Notes which will constitute an Event of Default under clause (2) above and other than a failure to comply with Article IV which is covered by clause (3));

(5) failure by the Parent Guarantor or any Restricted Subsidiary to comply with any agreement in this Indenture or the Notes (other than an agreement, a default in or failure to comply with that is elsewhere in this Section specifically dealt with) and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Parent Guarantor by the Trustee or to the Parent Guarantor and the Trustee by the Holders of at least 25% in principal amount of the outstanding Notes a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder;

102

(A) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (and any extensions of any grace period) (“payment default”); or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity (the “cross acceleration provision”);

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a payment default or the maturity of which has been so accelerated, aggregates $50.0 million or more;

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

(8) the commencement by the Parent Guarantor, the Issuer or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent Guarantor and its Restricted Subsidiaries) would constitute a Significant Subsidiary of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or similar law (including any Canadian Insolvency Law) or of any other case or proceeding to be adjudicated as bankrupt or insolvent, or the consent by it or them to the entry of a decree or order for relief or in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law (including any

(9) failure by the Parent Guarantor, the Issuer or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent Guarantor and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $50.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid or discharged, and there shall be any period of 60 consecutive days following entry of such final judgment or decree during which a stay of enforcement of such final judgment or decree, by reason of pending appeal or otherwise, shall not be in effect (the “judgment default provision”); or

(10) any Guarantee of the Parent Guarantor or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Parent Guarantor and its Restricted Subsidiaries) would constitute a Significant Subsidiary, ceases to be in full force and effect (except as contemplated by the terms of this Indenture) or is declared null and void in a judicial proceeding or the Parent Guarantor or any Subsidiary Guarantor that is a Significant Subsidiary or group of Subsidiary Guarantors that, taken together (as of the latest audited consolidated financial statements of the Parent Guarantor and its Restricted Subsidiaries) would constitute a Significant Subsidiary, denies or disaffirms its obligations under this Indenture or its Guarantee; or

104

(b) However, a default under clauses (4) and (5) of Section 6.1(a) will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes notify the Parent Guarantor in writing and, in the case of a notice given by the Holders, the Trustee of the default and the Parent Guarantor does not cure such default within the time specified in clauses (4) and (5) of Section 6.1(a) after receipt of such notice.

SECTION 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in clauses (7) and (8) of Section 6.1(a) with respect to the Issuer) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes by notice to the Issuer (and the Trustee in the case of a notice provided by the Holders), may declare the principal of, premium (including the Applicable Premium) and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal, premium (including the Applicable Premium) and interest shall be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default specified in clauses (7) and (8) of Section 6.1(a), all outstanding Notes will become immediately due and payable without any declaration or other action or notice on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the Notes by notice to the Trustee may rescind an 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 Notes are accelerated or otherwise become due prior to July 12, 2024 for any reason (including the acceleration of claims by operation of law), in each case, as a result of an Event of Default prior to December 21, 2021, the amount of principal of, accrued and unpaid interest and premium on the Notes that becomes due and payable shall equal 100% of the principal amount of the Notes redeemed plus the Applicable Premium in effect on the date of such acceleration, plus accrued and unpaid interest on the applicable Notes as of the date of acceleration, as if such acceleration were an optional redemption of the Notes pursuant to paragraph 5 of the Notes accelerated. If the Notes are accelerated or otherwise become due prior to July 12, 2024, in each case, as a result of an Event of Default on or after December 21, 2021, the amount of principal of, accrued and unpaid interest and premium on the Notes that becomes due and payable shall equal the redemption price applicable with respect to an optional redemption of the Notes pursuant to paragraph 5, in effect on the date of such acceleration, plus accrued and unpaid interest on the applicable Notes as of the date of acceleration, as if such acceleration were an optional redemption pursuant to paragraph 5 of the Notes accelerated.

Without limiting the generality of the foregoing, in the event the Notes are accelerated or otherwise become due prior to July 12, 2024, in each case, in respect of any Event of Default (including, but not limited to, upon the occurrence of an Event of Default specified in clauses (7) and (8) of Section 6.1(a) (including the acceleration of claims by operation of law)), the premium (including the Applicable Premium) payable with respect to an optional redemption pursuant to paragraph 5 of the Notes will also be due and payable as though the Notes were optionally

105

redeemed and shall constitute part of the Obligations, in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of each Holder’s lost profits as a result thereof. Any premium (including the Applicable Premium) payable above shall be presumed to be the liquidated damages sustained by each Holder as the result of the early redemption and the Issuer agrees that it is reasonable under the circumstances currently existing. The premium (including the Applicable Premium) shall also be payable in the event the Notes (and/or this Indenture) are satisfied or released by foreclosure (whether by power of judicial proceeding), deed in lieu of foreclosure or by any other means. THE ISSUER 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 (INCLUDING THE APPLICABLE PREMIUM) IN CONNECTION WITH ANY SUCH ACCELERATION. The Issuer expressly agrees (to the fullest extent it may lawfully do so) that: (A) the premium (including the Applicable Premium) is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the premium (including the Applicable Premium) shall be payable notwithstanding the then prevailing market rates at the time payment is made; (C) there has been a course of conduct between Holders and the Issuer giving specific consideration in this transaction for such agreement to pay the premium (including the Applicable Premium); and (D) the Issuer shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The Issuer expressly acknowledges that its agreement to pay the premium (including the Applicable Premium) to Holders as herein described is a material inducement to Holders to purchase the Notes.

In the event of any Event of Default specified in clause (6) of Section 6.1(a), such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders of the Notes, if within 30 days after such Event of Default arose the Issuer delivers an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the requisite number of Holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the Notes as described above be annulled, waived or rescinded upon the happening of any such events.

SECTION 6.3 Other Remedies. If an Event of Default occurs and is continuing with respect to the Notes, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of (or premium) or interest on the Notes or to enforce the performance of any provision of the Notes, this Indenture or the Guarantees with respect to such Notes.

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

106

SECTION 6.4 Waiver of Past Defaults. The Holders of a majority in principal amount of the outstanding Notes by notice to the Trustee (with a copy to the Issuer, but the applicable waiver or rescission shall be effective when the notice is given to the Trustee) may (a) waive, by their consent (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), an existing Default or Event of Default and its consequences except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest on a Note or (ii) a Default or Event of Default in respect of a provision that under Section 9.2 cannot be amended without the consent of each Noteholder affected and (b) rescind any acceleration with respect to the Notes and its consequences if (1) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

SECTION 6.5 Control by Majority. The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, the Notes or the Guarantees or, subject to Sections 7.1 and 7.2, that the Trustee determines is unduly prejudicial to the rights of other Noteholders 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 such action hereunder, the Trustee shall be entitled to indemnification or security satisfactory to it in its sole discretion against all losses, liabilities and expenses caused or that may be caused by taking or not taking such action.

SECTION 6.6 Limitation on Suits. Subject to Section 6.7, a Noteholder may not pursue any remedy with respect to this Indenture, the Note Security Documents or the Notes unless:

(1) such Holder has previously given to the Trustee written notice stating that an Event of Default with respect to the Notes is continuing;

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

(3) such Holders have offered to the Trustee security or indemnity, reasonably satisfactory to the Trustee, against any loss, liability or expense;

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

(5) the Holders of a majority in principal amount of the outstanding Notes have not waived such Event of Default or otherwise given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request during such 60-day period.

107

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

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

SECTION 6.8 Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.1(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.7.

SECTION 6.9 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Noteholders allowed in any judicial proceedings relative to the Issuer, the Parent Guarantor or the Subsidiary Guarantors or its or their respective creditors or properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter and may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation and reasonable expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7.

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

SECTION 6.10 Priorities. If the Trustee collects any money or property pursuant to this Article VI, it shall, subject to the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement, pay out the money in the following order:

FIRST: to the Collateral Agent and the Trustee for amounts due to it under Section 7.7, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the Collateral Agent the costs and expenses of collection;

108

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

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

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

SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by the Parent Guarantor or its Subsidiaries, a suit by a Holder pursuant to Section 6.7 or a suit by Holders of more than 10% in outstanding principal amount of the Notes.

ARTICLE VII

TRUSTEE

SECTION 7.1 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 its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

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

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture 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, opinions or orders furnished to the Trustee and conforming to the requirements of this Indenture, the Notes or the Guarantees, as applicable. However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture, the Notes or the Guarantees, as the case may be (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

109

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

(1) this Section 7.1(c) does not limit the effect of Section 7.1(b);

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

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5; and

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

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.1.

(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 Issuer. The Trustee shall not be required to give any bond or surety in respect of the performance of its powers or duties under the Indenture.

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

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

SECTION 7.2 Rights of Trustee. Subject to Section 7.1:

The Trustee need not investigate any fact or matter stated in the document. The Trustee shall receive and retain financial reports and statements of the Issuer as provided herein, but shall have no duty to review or analyze such reports or statements to determine compliance with covenants or other obligations of the Issuer.

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

110

(f) The Trustee shall not be deemed to have notice of any Default or Event of Default or whether any entity or group of entities constitutes a Significant Subsidiary unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default or of any such Significant Subsidiary is received by the Trustee at the corporate trust office of the Trustee specified in Section 12.2, and such notice references the Notes and this Indenture.

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

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

(i) Whenever in the administration of this Indenture, the Notes or the Guarantees the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder or thereunder, the Trustee (unless other evidence be herein specifically prescribed) may request and in the absence of bad faith or willful misconduct on its part, rely upon an Officers’ Certificate.

(j) In no event shall the Trustee be responsible or liable for any special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit), irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(k) The parties hereto acknowledge, in accordance with Section 326 of the Patriot Act, that the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The Issuer and the Guarantors agree that they will provide the Trustee with all such information as it may reasonably request in order to satisfy the requirements or its obligations under the Patriot Act.

111

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

(m) [Reserved].

(n) The Trustee may request that the Issuer deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

SECTION 7.3 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer, the Guarantors or their Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. In addition, the Trustee shall be permitted to engage in transactions with the Issuer; provided, however, that if the Trustee acquires any conflicting interest under the TIA, the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission to continue acting as Trustee or (iii) resign.

SECTION 7.4 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Guarantees or the Notes, shall not be accountable for the Issuer’s use of the proceeds from the sale of the Notes, shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee or any money paid to the Issuer pursuant to the terms of this Indenture and shall not be responsible for any statement of the Issuer in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication.

SECTION 7.5 Notice of Defaults. If a Default or Event of Default with respect to the Notes occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall send to each Noteholder in the manner provided in Section 12.02, notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium (if any), or interest on any Note (including payments pursuant to the optional redemption or required repurchase provisions of such Note), the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of Noteholders.

SECTION 7.6 Reports by Trustee to Holders.

A copy of each report at the time it is sent to Noteholders shall be filed with the SEC and each stock exchange (if any) on which the Notes are listed. The Issuer agrees to notify promptly the Trustee whenever the Notes become listed on any stock exchange and of any delisting thereof and the Trustee shall comply with TIA § 313(d).

112

SECTION 7.7 Compensation and Indemnity. The Issuer shall pay to the Trustee from time to time reasonable compensation for its services hereunder and under the Notes and the Guarantees as the Issuer and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including, but not limited to, costs of collection, costs of preparing reports, certificates and other documents, costs of preparation and sending of notices to Noteholders. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuer and the Guarantors shall, jointly and severally, indemnify the Trustee (including its officers, directors, agents and employees) against any and all loss, liability, damages, claims or expense (including reasonable attorneys’ fees and expenses) incurred by it without willful misconduct or gross negligence on its part (as determined by a final non-appealable order of a court of competent jurisdiction) in connection with the administration of this trust and the performance of its duties hereunder and under the Notes and the Guarantees, including the costs and expenses of enforcing this Indenture (including this Section 7.7), the Notes and the Guarantees and of defending itself against any claims (whether asserted by any Noteholder, the Issuer or otherwise). The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity of which it has received written notice. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee shall provide reasonable cooperation at the Issuer’s expense in the defense. The Trustee may have separate counsel and the Issuer shall pay the fees and expenses of such counsel; provided that the Issuer shall not be required to pay the fees and expenses of such separate counsel if it assumes the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Issuer and the Trustee in connection with such defense.

To secure the Issuer’s payment obligations in this Section 7.7, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of, premium, if any, and interest on particular Notes. Such lien shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee. The Trustee’s right to receive payment of any amounts due under this Section 7.7 shall not be subordinate to any other liability or Indebtedness of the Issuer.

The Issuer’s payment obligations pursuant to this Section 7.7 shall survive the discharge of this Indenture or the earlier resignation or removal of the Trustee. Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses after the occurrence of a Default specified in clause (7) or clause (8) of Section 6.1, the expenses are intended to constitute expenses of administration under any Bankruptcy Law. “Trustee” for purposes of this Section 7.7 shall include any predecessor Trustee; provided, however, the gross negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

113

SECTION 7.8 Replacement of Trustee. The Trustee may resign at any time by so notifying the Issuer in writing. The Holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the removed Trustee in writing and may appoint a successor Trustee with the Issuer’s written consent, which consent will not be unreasonably withheld. The Issuer shall remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10 hereof or TIA § 310;

(2) the Trustee is adjudged bankrupt or insolvent;

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

(4) the Trustee otherwise becomes incapable of acting.

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

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. 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 send a notice of its succession to Noteholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.7.

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

If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in TIA § 310(b), any Noteholder, who has been a bona fide Holder of a Note for at least six months, may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section 7.8, the Issuer’s obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

SECTION 7.9 Successor Trustee by Merger. If the Trustee 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 Notes 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 Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may

114

authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Notes in the name of any predecessor Trustee shall only apply to its successor or successors by merger, consolidation or conversion.

SECTION 7.10 Eligibility; Disqualification. This Indenture shall always have a Trustee that satisfies the requirements of TIA § 310(a)(1), (2) and (5) in every respect. The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuer are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

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

SECTION 7.12 Trustee’s Application for Instruction from the Issuer. Any application by the Trustee for written instructions from the Issuer may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any Officer of the Issuer actually receives such application, unless any such Officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

ARTICLE VIII

DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.1 Discharge of Liability on Notes; Defeasance.

(a) Subject to Section 8.1(c), when (i) either (x) all Notes that have been authenticated (other than Notes replaced or paid pursuant to Section 2.10 and such Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust), have been delivered to the Trustee for cancellation or (y) all outstanding Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption or otherwise, will become due and payable within one year or may 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 Issuer, and the Issuer or any Guarantor has irrevocably deposited or caused to be irrevocably deposited with the Trustee, as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, U.S. Government Obligations, or

115

a combination thereof, in such amounts as will be sufficient, in the opinion of an accounting, appraisal or investment banking firm of national standing, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of final maturity or redemption (provided that if such redemption is made as provided in the fifth paragraph of paragraph 5 of the form of Note attached hereto as Exhibit A, (1) the amount of cash in U.S. dollars, U.S. Government Obligations, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit and (2) the depositor must irrevocably deposit or cause to be deposited additional money in trust on the Redemption Date as necessary to pay the Applicable Premium as determined by such date); (ii) in respect of clause (i)(y), no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which either the Issuer or any Guarantor is a party or by which either the Issuer or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings); (iii) the Issuer has paid or caused to be paid all sums payable by it under this Indenture; and (iv) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Notes at final maturity or the Redemption Date, as the case may be, then the Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Issuer (accompanied by an Officers’ Certificate and an Opinion of Counsel, which may be subject to customary assumptions and exclusions, stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with) and at the cost and expense of the Issuer. If U.S. Government Obligations shall have been deposited in connection with such satisfaction and discharge, then as a further condition to such satisfaction and discharge, the Trustee shall have received a certificate from a nationally recognized firm of independent accountants to the effect set forth in Section 8.2(1).

(b) Subject to Sections 8.1(c) and 8.2, the Issuer at any time may terminate (i) all of its obligations under the Notes and this Indenture (“legal defeasance option”), and Liens on the Collateral securing the Notes will be released, and after giving effect to such legal defeasance, any omission to comply with such obligations shall no longer constitute a Default or Event of Default or (ii) its obligations under Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.8, 3.9, 3.10, 3.11, 3.19, 3.20 and 3.21, and clause (a)(3) of Section 4.1, and the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document and such omission to comply with such Sections shall no longer constitute a Default or an Event of Default under Section 6.1(a)(3) (as it relates to Section 4.1(a)(3) only), Section 6.1(a)(4) (to the extent applicable to such other defeased covenants), Section 6.1(a)(6), Section 6.1(a)(7) (only with respect to Significant Subsidiaries and a group of Restricted Subsidiaries constituting a Significant Subsidiary), Section 6.1(a)(8) (only with respect to Significant Subsidiaries and a group of Restricted Subsidiaries constituting a Significant

116

Subsidiary), Section 6.1(a)(9) and Section 6.1(a)(10) (other than with respect to the Guarantee of the Parent Guarantor), and the events specified in such Sections shall no longer constitute an Event of Default and the Liens on the Collateral securing the Notes will be released (clause (ii) being referred to as the “covenant defeasance option”), but except as specified above, the remainder of this Indenture and the Notes shall be unaffected thereby. The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Issuer exercises its legal defeasance or its covenant defeasance option, the Guarantees in effect at such time shall terminate.

If the Issuer exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default. If the Issuer exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in Section 6.1(a)(3) (as it relates to Section 4.1(a)(3) only), Section 6.1(a)(4) (to the extent applicable to Sections 3.2, 3.3, 3.4, 3.5, 3.6, 3.8, 3.9, 3.10, 3.11, 3.19, 3.20 and 3.21), Section 6.1(a)(6), Section 6.1(a)(7) (only with respect to Significant Subsidiaries and a group of Restricted Subsidiaries constituting a Significant Subsidiary), Section 6.1(a)(8) (only with respect to Significant Subsidiaries and a group of Restricted Subsidiaries constituting a Significant Subsidiary), Section 6.1(9) or Section 6.1(10) (other than with respect to the Guarantee of the Parent Guarantor).

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

(c) Notwithstanding the provisions of Sections 8.1(a) and (b) to the extent relating to a satisfaction and discharge or a legal defeasance, the Issuer’s obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.10, 2.11, 2.12, 2.13, 2.18, 7.7 and 7.8 and in this Article VIII shall survive until the Notes have been paid in full. Thereafter, the Issuer’s obligations in Sections 7.7, 8.4 and 8.5 shall survive.

SECTION 8.2 Conditions to Defeasance. The Issuer may exercise its legal defeasance option or its covenant defeasance option with respect to Notes only if:

(1) in accordance with Section 8.1, the Issuer irrevocably deposits with the Trustee, in trust, for the benefit of the Holders of Notes, cash in U.S. dollars, U.S. Government Obligations, or a combination of cash in U.S. dollars and U.S. Government Obligations, in amounts as will be sufficient, in the opinion of an accounting, appraisal or investment banking firm of national standing, to pay the principal of, and premium, if any, and interest, if any, due on the outstanding Notes on the Stated Maturity or on the applicable Redemption Date, as the case may be, and the Issuer must specify whether such Notes are being defeased to Stated Maturity or to a particular Redemption Date (provided that if such redemption is made as provided in the fifth paragraph of paragraph 5 of the form of Note attached hereto as Exhibit A, (x) the amount of cash in U.S. dollars, U.S. Government Obligations, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money in trust on the Redemption Date as necessary to pay the Applicable Premium as determined on such date);

117

(2) in the case of legal defeasance, the Issuer has delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) confirming that, subject to customary assumptions and exclusions, (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Beneficial Owners of the respective outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such legal defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred;

(3) in the case of covenant defeasance, the Issuer has delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) confirming that the Beneficial Owners of the respective outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred;

(4) no Default or Event of Default has occurred and is continuing on the date of such deposit or will occur as a result of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the grant of any Lien securing such borrowings);

(5) such legal defeasance or covenant defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries are bound;

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

(7) the Issuer must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions), each stating that all conditions precedent relating to the legal defeasance or the covenant defeasance have been complied with; and

(8) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the Redemption Date, as the case may be (which instructions may be contained in the Officers’ Certificate referred to in clause (7) above).

118

SECTION 8.3 Application of Trust Money. The Trustee shall hold in trust all money or U.S. Government Obligations (including proceeds thereof) deposited with it pursuant to this Article VIII. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture and the Notes to the Holders of all sums due in respect of the payment of principal of, premium, if any, and accrued interest on the Notes.

SECTION 8.4 Repayment to the Issuer. The Trustee and the Paying Agent shall promptly turn over to the Issuer upon request any excess money, U.S. Government Obligations or other Notes held by them upon payment of all the Obligations under this Indenture.

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

SECTION 8.5 Indemnity for U.S. Government Obligations. The Issuer 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 8.6 Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article VIII by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Issuer and each Guarantor under this Indenture, the Notes and the Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article VIII; provided, however, that, if the Issuer or the Guarantors have made any payment of principal, premium, if any, or interest on any Notes because of the reinstatement of their obligations, the Issuer or Guarantors, as the case may be, shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

The Trustee’s rights under this Article VIII shall survive termination of this Indenture.

ARTICLE IX

AMENDMENTS

SECTION 9.1 Without Consent of Holders. The Issuer, the Guarantors (in the case of the Subsidiary Guarantors, with respect to its Guarantee), the Collateral Agent (if applicable) and the Trustee may amend or supplement this Indenture, the Notes, the Note Security Documents, the Intercreditor Agreement, the Third Lien Intercreditor Agreement and the related Guarantees without notice to or consent of any Noteholder:

(10) to provide for the issuance of Additional Notes and PIK Notes in accordance with the provisions of this Indenture;

(11) to modify this Indenture solely for the purpose of providing the removal of the Restricted Securities Legend, if any, on any Note and to allow for the transfer of a Definitive Note or a beneficial interest in a Global Note to a Note that has an unrestricted CUSIP number, in each case in accordance with applicable securities laws.

(12) to make, complete or confirm any grant of Liens on Collateral permitted or required by this Indenture or any of the Note Documents or the Intercreditor Agreement; or

(13) to release or subordinate Liens on Collateral in accordance with this Indenture, the Note Security Documents and the Intercreditor Agreement.

120

After an amendment, supplement, or waiver under this Section 9.1 becomes effective, the Parent Guarantor shall send to Noteholders (with a copy to the Trustee) a notice briefly describing such amendment. The failure to give such notice to all Noteholders, or any defect therein, shall not impair or affect the validity of an amendment, supplement or waiver under this Section.

In addition, the Holders will be deemed to have consented to, and shall be deemed to have directed the Trustee and/or the Collateral Agent (as applicable), to execute and deliver any of the following amendments, waivers and other modifications to the Note Security Documents, in each case, as evidenced by an Officers’ Certificate and Opinion of Counsel delivered to the Trustee and the Collateral Agent pursuant to Section 12.4 and Section 12.5 hereof:

(1) to add other parties (or any authorized agent thereof or trustee therefor) holding Priority Obligations that are incurred in compliance with the Revolving Credit Facility, this Indenture and the Security Documents and (B) to establish that the Liens on any Collateral securing such Priority Obligations shall rank equally under the Intercreditor Agreement with the Liens on such Collateral securing the obligations under the Senior Secured Credit Agreements and senior to the Liens on such Collateral securing any obligations under this Indenture, the Notes and the Guarantees, all on the terms provided for in the Intercreditor Agreement as in effect immediately prior to such amendment;

(2) to establish that the Liens on any Collateral securing any Indebtedness replacing the Senior Secured Credit Agreements permitted to be Incurred under Section 3.2 that represent Priority Obligations shall be senior to the Liens on such Collateral securing any obligations under this Indenture, the Notes and the Guarantees, which obligations shall continue to be secured on a second-priority basis on the Collateral; and

(3) upon any cancellation or termination of the Senior Secured Credit Agreements and all other Priority Obligations without a replacement thereof, to establish that the Collateral securing the Notes and the Guarantees shall become first priority Collateral, except as set forth below under Section 11.5.

SECTION 9.2 With Consent of Holders. The Issuer, the Guarantors, the Collateral Agent (as applicable) and the Trustee may amend or supplement this Indenture, the Notes, the Intercreditor Agreement, the Third Lien Intercreditor Agreement and any other Note Security Documents and the related Guarantees without notice to any Noteholder but with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). Except as provided in Section 6.4, any past default or compliance with the provisions of this Indenture, the Notes or the related Guarantees may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). However, without the consent of each Noteholder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder):

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

121

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

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

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

(5) (i) reduce the premium payable upon the redemption of any Note as described in Article V hereof or paragraph 5 of any Note, (ii) change the time at which any Note may be redeemed as described in Article V hereof or paragraph 5 of any Note (except provisions relating to minimum required notice of optional redemption) or (iii) make any change relative to the Issuer’s obligation to make an offer to repurchase the Notes as a result of a Change of Control Triggering Event as described in Section 3.9 after (but not before) the occurrence of such Change of Control Triggering Event; provided that the Issuer shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of any Notes for or as an inducement to any consent, waiver or amendment relating to the obligations set forth in clause (iii) of this Section 9.2(5) unless such consideration is offered to be paid and is paid to all holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment;

(6) make any Note payable other than that stated in such Note;

(7) amend the contractual right expressly set forth in this Indenture with respect to the Notes or any Note of any Holder to institute a suit for the enforcement of any payment of principal, premium, if any, and interest on such Holder’s Notes on or after the due dates therefor;

(8) make any change to this Section 9.2 which requires the consent of each Holder of the Notes;

(9) modify the Guarantees in any manner adverse to the Holders of Notes; or

(10) make any change to or modify the ranking or the priority of the Liens securing the Notes that would adversely affect the Holders of such Notes.

In addition, notwithstanding anything to the contrary in this Section 9.2, the consent of Holders representing at least 66²⁄₃% of outstanding Notes will be required to release the Liens for the benefit of the holders of the Notes on all or substantially all of the Collateral, other than in accordance with this Indenture, the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (as applicable).

122

It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, supplement, or waiver, but it shall be sufficient if such consent approves the substance thereof. A consent to any amendment, supplement or waiver under this Indenture by any Holder of the Notes given in connection with a tender or exchange of such Holder’s Notes will not be rendered invalid by such tender or exchange.

After an amendment, supplement, or waiver under this Section becomes effective, the Parent Guarantor shall send to Noteholders (with a copy to the Trustee) a notice briefly describing such amendment. The failure to give such notice to all Noteholders, or any defect therein, shall not impair or affect the validity of an amendment, supplement or waiver under this Section 9.2.

SECTION 9.3 [Reserved].

SECTION 9.4 Revocation and Effect of Consents and Waivers. A consent to an amendment, supplement or a waiver by a Holder of a Note shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note. Any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee and the Issuer receive the notice of revocation before the date the amendment, supplement or waiver becomes effective or otherwise in accordance with any related solicitation documents. After an amendment, supplement or waiver becomes effective, it shall bind every Noteholder unless it makes a change described in any of clauses (1) through (10) of Section 9.2, and in that case the amendment, supplement, waiver or other action shall bind each Noteholder who has consented to it and every subsequent Noteholder that evidences the same debt as the consenting Holder’s Notes. An amendment, supplement or waiver under Section 9.2 shall become effective upon receipt by the Issuer of the requisite number of consents, and in relation to any Notes evidenced by Global Notes, such consents need not be in written form and may be evidenced by any electronic transmissions that comport with the applicable procedures of DTC.

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

SECTION 9.5 Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Issuer or the Trustee may require the Holder of the Note to deliver it to the Trustee. The Issuer may instruct the Trustee to place a notation designated by the Issuer on the Note regarding the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, the Issuer in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment.

123

SECTION 9.6 Trustee to Sign Amendments. The Trustee or the Collateral Agent (as applicable) shall sign any amendment, supplement or waiver authorized pursuant to this Article IX if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee or the Collateral Agent (as applicable). If it does, the Trustee or the Collateral Agent (as applicable) may but need not sign it. In signing any amendment, supplement or waiver the Trustee or the Collateral Agent (as applicable) shall be entitled to receive indemnity satisfactory to it and shall be provided with, and (subject to Sections 7.1 and 7.2) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and any Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof.

ARTICLE X

GUARANTEE

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

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

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

Except as set forth in Section 10.2, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the

124

Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Issuer or any other person under this Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder for the Obligations or any of them; (e) the failure of any Holder to exercise any right or remedy against any other Guarantor; (f) any change in the ownership of the Issuer; (g) any default, failure or delay, willful or otherwise, in the performance of the Obligations; or (h) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor agrees that its Guarantee herein shall remain in full force and effect until payment in full of all the Obligations or such Guarantor is released from its Guarantee upon the merger or the sale of all the Capital Stock or assets of the Guarantor or otherwise in compliance with Article IV, Section 10.2 or Article VIII, as applicable. Each Guarantor further agrees that its Guarantee herein 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, premium, if any, or interest on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Issuer or otherwise.

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

Each Guarantor further agrees that, as between such Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of this Guarantee.

Each Guarantor also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee, the Collateral Agent or the Holders in enforcing any rights under this Section 10.1.

Neither the Issuer nor the Guarantors shall be required to make a notation on the Notes to reflect any Guarantee or any release, termination or discharge thereof and any such notation shall not be a condition to the validity of any Guarantee.

125

SECTION 10.2 Limitation on Liability; Termination, Release and Discharge.

(a) Any term or provision of this Indenture to the contrary notwithstanding, the obligations of each Subsidiary Guarantor hereunder will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including, without limitation, any guarantees under the Senior Secured Credit Agreements) and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Subsidiary Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

(b) Upon the sale or disposition of a Subsidiary Guarantor, whether by merger, consolidation, the sale of a sufficient amount of its Capital Stock so that it no longer qualifies as a “Subsidiary” of the Issuer or the sale of all or substantially all of its assets (other than by lease) and whether or not such Subsidiary Guarantor is the surviving entity in such transaction, to a Person which is not the Parent Guarantor or a Restricted Subsidiary, such Subsidiary Guarantor will be released from all its obligations under this Indenture and its Guarantee if the sale or other disposition does not violate Section 3.5.

(c) [Reserved].

(d) Each Subsidiary Guarantor will be released from its obligations under this Indenture and its Guarantee if the Parent Guarantor designates such Subsidiary Guarantor as an Unrestricted Subsidiary and such designation complies with the other applicable provisions of this Indenture.

(e) Each Subsidiary Guarantor will be deemed released from all its obligations under this Indenture and its Guarantee, and such Guarantee will terminate, upon any covenant defeasance of the Notes.

(f) Each Guarantor will be deemed released from all its obligations under this Indenture and its Guarantee, and such Guarantee will terminate, upon any legal defeasance or upon satisfaction and discharge of this Indenture, in each case pursuant to the provisions of Article VIII hereof.

(g) The release of any Guarantor from its obligations pursuant to this Section 10.2 shall be conditioned upon such Guarantor delivering to the Trustee and the Collateral Agent an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent provided for in this Indenture relating to the transactions specified in clauses (b), (c), (d) (e), or (f) of this Section 10.2 have been complied with.

SECTION 10.3 Right of Contribution. Each Guarantor hereby agrees that to the extent that any Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the Guarantees, such Guarantor shall be entitled to seek and receive contribution from and against the Issuer or any other Guarantor who has not paid its proportionate share of such payment. The provisions of this Section 10.3 shall in no respect limit the obligations and liabilities of each Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee, the Collateral Agent and the Holders for the full amount guaranteed by such Guarantor hereunder.

126

SECTION 10.4 No Subrogation. Notwithstanding any payment or payments made by each Guarantor hereunder, no Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Issuer or any other Guarantor or guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Issuer or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee, the Collateral Agent and the Holders by the Issuer on account of the Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the Obligations.

128

(c) Within 60 days of the Issue Date (or as such period may be extended by the Credit Facility Agent but in no event later than 90 days of the Issue Date), the Issuer and the Guarantors shall execute and deliver, and cause all other required parties thereto to execute and deliver, to the Collateral Agent the control agreements required by the Note Security Documents, and shall otherwise comply with the requirements of all Note Security Documents with respect to control agreements; provided that, (i) at any time prior to the Discharge of Senior Obligations (as defined in the Intercreditor Agreement), with respect to any account for which a control agreement with the First Lien Collateral Agent (as defined in the Intercreditor Agreement) is in effect (any such account, a “First Lien Collateral Agent Controlled Account”), the Issuer shall only be required to use commercially reasonable efforts to execute and deliver and cause all other required parties to execute and deliver such control agreements and otherwise comply with such requirements within such time period and (ii) with respect to any such First Lien Collateral Agent Controlled Account, upon the Discharge of Senior Obligations or such account otherwise ceasing to be a First Lien Collateral Agent Controlled Account, the Issuer shall execute and deliver, and cause all other required parties thereto to execute and deliver, such control agreements and otherwise comply with such requirements within 60 days of the date of the Discharge of Senior Obligations or such account otherwise ceasing to be a First Lien Collateral Agent Controlled Account.

SECTION 11.3 Further Assurances; Liens on Additional Property.

(a) The Issuer and each of the Guarantors shall do or cause to be done all acts and things that may be required, or that the Collateral Agent from time to time may reasonably request, to assure and confirm that the Collateral Agent holds, for the benefit of the holders of Parity Lien Obligations, duly created and enforceable and perfected second priority Liens (subject in priority to the Priority Liens and subject to the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and to Permitted Liens) upon the Collateral (including any acquired property or other property 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, and in connection with any merger, consolidation or sale of assets of any Issuer or any Guarantor, the property and assets of the

129

Person which is consolidated or merged with or into any Issuer or any Guarantor, to the extent that they are property or assets of the types which would constitute Collateral under the Note Security Documents, shall be treated as after-acquired property and such Issuer or such Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Parity Liens, in the manner and to the extent required under the Parity Lien Documents.

(b) Each Issuer and each of the Guarantors shall promptly execute, acknowledge and deliver such Note Security Documents, instruments, certificates, financing statements, notices and other documents, and take such other actions as shall be reasonably required, or that the Collateral Agent or any Parity Lien Representative 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 and, prior to the Discharge of Senior Obligations, only if delivered pursuant to the applicable Priority Lien Debt Documents, cause its counsel to deliver a favorable legal opinion with respect thereto in form and substance substantially consistent with the opinions delivered pursuant to the applicable Priority Lien Debt Documents; provided, that no such Note Security Document, instrument or other document shall be materially more burdensome upon the Issuer and the Guarantors than the Parity Lien Documents executed and delivered (or required to be executed and delivered promptly after the date of this Indenture by the Issuer and the Guarantors in connection with the issuance of the Notes on or about the Issue Date).

(c) In addition to the Collateral, from and after the Issue Date, if any Issuer or any Guarantor acquires any property that constitutes collateral for the Priority Lien Debt or Junior Lien Debt, if and to the extent that 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, the Issuer shall, or shall cause the applicable Guarantor to, promptly (but not in any event no later than the date that is 20 Business Days after 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 Agent appropriate Note Security Documents (or amendments thereto) in such form as shall be necessary to grant the Collateral Agent a valid and enforceable perfected second-priority Lien (subject in priority to the Priority Liens and subject to the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and to Permitted Liens) on such Collateral or take such other actions in favor of the Collateral Agent as shall be reasonably necessary to grant a valid and enforceable perfected second-priority Lien (subject in priority to the Priority Liens and subject to the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and to Permitted Liens) on such Collateral to the Collateral Agent, for the benefit of the Holders of the Notes and holders of any other 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 any Issuer or any Guarantor creates any additional Lien upon any property that would constitute Collateral, or takes any additional actions to perfect any existing 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, such Issuer or such Guarantor, as applicable, must, 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

130

perfected second-priority Lien (subject in priority to the Priority Liens and subject to the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and to Permitted Liens) upon such property or asset, or take such additional perfection actions, as applicable, for the benefit of the Holders and obtain all related deliverables as those delivered to the Priority Lien Representative or Junior Lien Agent, as applicable, in each case as security for the Notes Obligations. Notwithstanding the foregoing, to the extent that any Lien on any Collateral is perfected by the possession of such Collateral, and if such Collateral is in fact in the possession of the Priority Lien Representative or of bailees of the Priority Lien Representative, the perfection actions and related deliverables described in this clause (c) shall not be required.

(d) Notwithstanding anything herein or in the Note Documents to the contrary, neither the Issuer nor the Guarantors will be required to grant a security interest in, and the Collateral shall not include, any collateral securing Priority Lien Obligations that is or may be provided to certain issuers or providers of Hedging Obligations or cash management services pursuant to the Priority Lien Documents rather than generally to the holders of Priority Lien Obligations or to the Priority Lien Collateral Agent for the benefit of the holders of Priority Lien Obligations as a whole.

(e) The Issuer will deliver to the Collateral Agent semi-annually on or before January 1 and July 1 in each calendar year, beginning July 1, 2019, an Officers’ Certificate certifying that, as of the date of such certificate, the Collateral includes proven Oil and Gas Properties that include not less than 95% of the total discounted present value of proved reserves attributable to the Oil and Gas Properties of the Parent Guarantor, on a consolidated basis, as evaluated in the Parent Guarantor’s most recent consolidated reserve report (which such total discounted present value shall, during any such time as any Priority Lien Obligations are outstanding or commitments therefor remain outstanding, be determined using the total discounted present value methodology then in effect under the Priority Lien Debt Documents, and, at any time thereafter, using the total discounted present value methodology in effect under the Term Loan Credit Agreement in place on the Issue Date during a Term Loan Exclusive Period (as such term is defined in the Term Loan Credit Agreement on the Issue Date), after giving effect to exploration and production activities, acquisitions, dispositions and production since the date of such reserve report (the “minimum mortgage requirement”). In the event that the Collateral does not represent the minimum mortgage requirement and, in any event, at any time at which a mortgage for Oil and Gas Properties is delivered pursuant to or in connection with the Priority Lien Debt Documents, then the Company shall, or shall cause the applicable Guarantor to, at the time of delivery of such mortgage or within 30 days of delivery of the certificate required under this clause (e) (or as such period may be extended by the Credit Facility Agent but in no event later than 90 days after delivery of the certificate required under this clause (e)), as applicable, execute and deliver to the Collateral Agent: (i) such executed mortgages or amendments or supplements to prior mortgages naming the Collateral Agent, as mortgagee or beneficiary, as may be necessary to cause the minimum mortgage requirement to be satisfied and (ii) satisfactory evidence of the completion (or satisfactory arrangements for the completion) of all recordings and filings of such mortgages, amendments or supplements in the proper recorders’ offices or appropriate public records (and payment of any recording taxes or fees in connection therewith).

131

(f) The Issuer will deliver to the Trustee copies of all documents delivered to the Collateral Agent pursuant to the Note Security Documents.

SECTION 11.4 Intercreditor Agreement and Third Lien Intercreditor Agreement. This Article XI and the provisions of each other Note Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor Agreement. Each Issuer and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof. Each Holder, by its acceptance of the Notes (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 Collateral Agent on behalf of each Holder to enter into the Intercreditor Agreement as Parity Lien Collateral Agent (as defined in the Intercreditor Agreement) on behalf of such Holders of Notes as Parity Lien Secured Parties (as defined in the Intercreditor Agreement). In addition, each Holder authorizes and instructs the Collateral Agent to enter into any amendments or joinders to the Intercreditor Agreement, without the consent of any Holder or the Trustee, to add additional Indebtedness as Priority Lien Debt, or permitted Refinancing Indebtedness constituting Secured 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 (if any) or Junior Lien Debt (if any), as applicable. The foregoing provisions are intended as an inducement to the lenders under the Credit Agreement to extend credit to the Company and certain of its Subsidiaries, and such lenders are intended third party beneficiaries of such provisions and the provisions of the Intercreditor Agreement.

In connection with the incurrence by the Issuer or any Guarantor thereof of any Junior Lien Debt or Permitted Third Lien Indebtedness permitted to be incurred pursuant to the terms hereof and of any other then outstanding Priority Lien Documents, Parity Lien Documents and Junior Lien Documents, Holders, by their acceptance of the Notes, authorize and direct the Collateral Agent on behalf of each Holder to enter into the Third Lien Intercreditor Agreement substantially in the form attached hereto as Exhibit C of this Indenture. In addition, each Holder (a) agrees that it will be bound by, and will take no actions contrary to, the provisions of the Third Lien Intercreditor Agreement, (b) authorizes and instructs the Collateral Agent to, without the consent of any Holder or the Trustee, enter into any supplements, joinders or confirmations to the Third Lien Intercreditor Agreement and any amendments, amendments and restatements, restatements or waivers of or supplements to or other modifications to any Security Document to add additional Indebtedness as Third Lien Indebtedness, or permitted Refinancing Indebtedness constituting Secured 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 third in priority with the Liens on such Collateral securing the other Priority Lien Debt, Parity Lien Debt (if any) or Junior Lien Debt (if any), as applicable, and (c) to make or consent to any filings or take any other actions in connection therewith, as may be reasonably deemed by the Issuer to be necessary or reasonably desirable for any Lien on the assets of the Issuer or any Subsidiary permitted to secure such Indebtedness to become a valid, perfected lien (with such priority as may be designated by the Issuer, the relevant Guarantor or Subsidiary, to the extent such priority is permitted by the Note Documents) pursuant to the Security Documents being so amended, amended and restated, restated, waived, supplemented or otherwise modified or otherwise, and, in each case, as set forth in an Officers’ Certificate delivered to the Collateral Agent.

132

SECTION 11.5 Release of Liens in Respect of Notes. The Collateral Agent’s other Liens upon the Collateral will no longer secure the Notes outstanding under this Indenture or any other Obligations, and the right of the Holders of the Notes to the benefits and proceeds of the Collateral Agent’s Liens on the Collateral will automatically terminate and be discharged:

(1) upon satisfaction and discharge of this Indenture in accordance with Article VIII hereof;

(2) upon a legal defeasance or covenant defeasance of the Notes in accordance with Article VIII hereof;

(3) upon payment in full in cash and discharge of all Notes 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 Notes are paid in full and discharged;

(5) in whole or in part, with the consent of the Holders of the requisite percentage of Notes in accordance with Article IX hereof;

(6) with respect to the assets of any Guarantor, at the time that such Guarantor is released from its Guarantee in accordance with Section 10.2;

(7) if and to the extent required by Section 5.01 of the Intercreditor Agreement; or

(8) the release of Excess Proceeds that remain unexpended after the conclusion of an Asset Disposition Offer conducted in accordance with Section 3.5.

With respect to any release of Collateral, upon receipt of (a) an Officers’ Certificate and Opinion of Counsel stating that all conditions precedent under this Indenture and the Note Security Documents and the Intercreditor Agreement, if any, to such release have been met and (b) any necessary or proper instruments of termination, satisfaction or release prepared by the Company, the Collateral Agent shall execute, deliver, authorize or acknowledge (at the Company’s expense) such instruments or releases to evidence the release of any Collateral permitted to be released pursuant to this Indenture or the Note Security Documents or the Intercreditor Agreement. Neither the Trustee nor the Collateral Agent shall be liable for any such

133

release undertaken in reliance upon any such Officers’ Certificate and Opinion of Counsel, and notwithstanding any term hereof or in any Note Security Document or in the Intercreditor Agreement to the contrary, the Trustee and the Collateral Agent shall not be under any obligation to release any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction or termination, unless and until it receives such Officers’ Certificate and Opinion of Counsel.

SECTION 11.6 Insurance.

(a) The Issuer and the Guarantors shall:

(1) maintain insurance with respect to their properties and business at all times by financially sound and reputable insurers, to such extent and against such risks as is customarily insured against by Persons in the same or similar businesses operating in the same or similar locations, and of such types and in such amounts as are customarily carried under similar circumstances; and

(2) maintain such other insurance as may be required by law.

(b) Upon the request of the Collateral Agent, the Issuer and the Guarantors will furnish to the Collateral Agent information as to their property and liability insurance carriers.

SECTION 11.7 Suits to Protect the Collateral. Subject to the provisions of Article VI and the Note Documents, the Trustee may or may direct the Collateral Agent to take all actions it determines in order to:

(a) enforce any of the terms of the Note Security Documents; and

(b) Subject to the provisions of the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable), the Trustee and the Collateral Agent shall have power to institute and to maintain such suits and proceedings as the Trustee may determine to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of any of the Note Security Documents or this Indenture, and such suits and proceedings as the Trustee may determine to preserve or protect its interests and the interests of the Holders in the Collateral. Nothing in this Section 11.7 shall be considered to impose any such duty or obligation to act on the part of the Trustee or the Collateral Agent.

SECTION 11.8 Purchaser Protected. In no event shall any purchaser in good faith of any property purported to be released hereunder be bound to ascertain the authority of the Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property or rights permitted by this Article XI to be sold be under any obligation to ascertain or inquire into the authority of the Issuer or the applicable Guarantor to make any such sale or other transfer.

134

SECTION 11.9 Powers Exercisable by Receiver or Trustee. In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article XI upon the Issuer or a Guarantor with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuer or a Guarantor or of any Officer or Officers thereof required by the provisions of this Article XI; and if the Trustee shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee.

SECTION 11.10 Collateral Agent.

(a) The Issuer, the Trustee and each of the Holders by acceptance of the Notes hereby designates and appoints the Collateral Agent as its agent under this Indenture, the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and the Issuer, the Trustee and each of the Holders by acceptance of the Notes hereby irrevocably authorizes the Collateral Agent to take such action on their behalf under the provisions of this Indenture, the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture, the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable), and consents and agrees to the terms of the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and each Note Security Document, as the same may be in effect or may be amended, restated, supplemented or otherwise modified from time to time in accordance with their respective terms. The Collateral Agent hereby accepts such designation and appointment and agrees to act as such on the express conditions contained in this Section 11.10. Each Holder agrees that any action taken by the Collateral Agent in accordance with the provisions of this Indenture, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents, and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture, the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable), the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder or any Grantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture, the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture or the other Note Documents with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

135

(b) The Collateral Agent may perform any of its duties under this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) by or through receivers, agents, employees, attorneys-in-fact or with respect to any specified Person, such Person’s Affiliates, and the respective officers, directors, employees, agents, advisors and attorneys-in-fact of such Person and its Affiliates (a “Related Person”), and shall be entitled to advice of counsel concerning all matters pertaining to such duties, and shall be entitled to act upon, and shall be fully protected in taking action in reliance upon, any advice or opinion given by legal counsel. The Collateral Agent shall not be responsible for the negligence or misconduct of any receiver, agent, employee, attorney-in-fact or Related Person that it selects as long as such selection was made in good faith and with due care, but such receiver, agent, employee, attorney-in-fact or Related Person shall be liable to the Issuer for any losses caused by their gross negligence or willful misconduct (as determined by a final non-appealable order of a court of competent jurisdiction).

(c) None of the Collateral Agent or any of its respective Related Persons shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence or willful misconduct (as determined by a final non-appealable order of a court of competent jurisdiction)) or under or in connection with any Note Security Document, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) or the transactions contemplated thereby (except for its own gross negligence or willful misconduct (as determined by a final non-appealable order of a court of competent jurisdiction)), or (ii) be responsible in any manner to any of the Trustee or any Holder for any recital, statement, representation, warranty, covenant or agreement made by the Issuer or any other Grantor or Affiliate of any Grantor, or any Officer or Related Person thereof, contained in this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable), or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable), or the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable), or for any failure of any Grantor or any other party to this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) to perform its obligations hereunder or thereunder. None of the Trustee, the Collateral Agent or any of its respective Related Persons shall be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) or to inspect the properties, books, or records of any Grantor or any Grantor’s Affiliates.

(d) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, certification, telephone message, statement, or other communication, document or conversation (including those by telephone or e-mail) believed by it in good faith to be genuine and correct and to have been signed, sent, or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limitation, counsel to the Issuer or any

136

other Grantor), independent accountants and other experts and advisors selected by the Collateral Agent. The Collateral Agent shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, or other paper or document. Notwithstanding anything to the contrary contained herein, the Collateral Agent shall act solely pursuant to the instructions of the Holders and the Trustee with respect to the Notes Security Documents and the Collateral. The Collateral Agent shall be fully justified in failing or refusing to take any action under this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) unless it shall first receive such advice or concurrence of the Trustee or the Holders of a majority in aggregate principal amount of the Notes as it determines and, if it so requests, it shall first be indemnified to its satisfaction by the Holders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Except as otherwise provided in the Note Security Documents, the Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) in accordance with a request, direction, instruction or consent of the Trustee or the Holders of a majority in aggregate principal amount of the then outstanding Notes and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Holders.

(e) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless a Trust Officer of the Collateral Agent shall have received written notice of such Default or Event of Default from the Trustee or the Issuer referring to this Indenture, describing such Default or Event of Default. The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Section 6.1 or the Holders of a majority in aggregate principal amount of the Notes (subject to this Section 11.10), subject to the terms of the Note Security Documents.

(f) The Collateral Agent may resign at any time by notice to the Trustee and the Issuer, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture, the Issuer shall appoint a successor collateral agent. If no successor collateral agent is appointed prior to the intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation, which date shall not be earlier than 20 Business Days following the date on which such notice is delivered to the Issuer), the Trustee, at the direction of the Holders of a majority of the aggregate principal amount of the Notes then outstanding, may appoint a successor collateral agent, subject to the consent of the Issuer (which consent shall not be unreasonably withheld and which shall not be required during a continuing payment or bankruptcy Event of Default). If no successor collateral agent is appointed and consented to by the Issuer pursuant to the preceding sentence within 30 days after the intended effective date of resignation (as stated in the notice of resignation) the Collateral Agent shall be entitled to petition a court of competent jurisdiction to appoint a successor. Upon the acceptance of its appointment as successor collateral agent hereunder, such successor collateral agent shall succeed to all the rights, powers and duties of the retiring Collateral Agent, and the term “Collateral Agent” shall mean such successor collateral agent, and the retiring Collateral Agent’s appointment, powers and duties as the Collateral Agent shall be terminated. After the retiring Collateral Agent’s resignation hereunder, the provisions of Section 7.7 and this Section 11.10 shall continue to inure to its benefit and the retiring Collateral Agent shall not by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to be taken by it while it was the Collateral Agent under this Indenture.

137

(g) Except as otherwise explicitly provided herein or in the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable), neither the Collateral Agent nor any of its respective officers, directors, employees or agents or other Related Persons shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be responsible for any act or failure to act hereunder, except for its own gross negligence or willful misconduct (as determined by a final non-appealable order of a court of competent jurisdiction).

(h) The Collateral Agent is authorized and directed to (i) enter into the Note Security Documents to which it is party, whether executed on or after the Issue Date, (ii) enter into the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable), (iii) make the representations of the Holders set forth in the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable), (iv) bind the Holders on the terms as set forth in the Note Security Documents and the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable) and (v) perform and observe its obligations under the Note Documents the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable).

(i) Neither the Trustee nor the Collateral Agent shall have any obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by any Grantor or is cared for, protected, or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Grantor’s property constituting collateral intended to be subject to the Lien and security interest of the Note Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture, any Note Security Document, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) other than pursuant to the instructions of the Trustee or the Holders of a majority in aggregate principal amount of the Notes accompanied by indemnity satisfactory to the Collateral Agent in its sole discretion or as otherwise provided in the Note Security Documents.

(j) No provision of this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) or any Note Security Document shall require the Collateral Agent (or the Trustee) to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of Holders (or

138

the Trustee in the case of the Collateral Agent) unless it shall have received indemnity satisfactory to the Collateral Agent and the Trustee against potential costs and liabilities incurred by the Collateral Agent relating thereto. Notwithstanding anything to the contrary contained in this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) or the Note Security Documents, in the event the Collateral Agent is entitled or required to commence an action to foreclose or otherwise exercise its remedies to acquire control or possession of the Collateral, the Collateral Agent shall not be required to commence any such action or exercise any remedy or to inspect or conduct any studies of any property under the mortgages or take any such other action if the Collateral Agent has determined that the Collateral Agent may incur personal liability as a result of the presence at, or release on or from, the Collateral or such property, of any hazardous substances. The Collateral Agent shall at any time be entitled to cease taking any action described in this clause if it no longer reasonably deems any indemnity, security or undertaking from the Issuer or the Holders to be sufficient. The Collateral Agent shall be entitled to the same protections as the Trustee specified in Article VII.

(k) The Collateral Agent (i) shall not be liable for any action taken or omitted to be taken by it in connection with this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents or instrument referred to herein or therein, except to the extent that any of the foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct, (ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Issuer (and money held in trust by the Collateral Agent need not be segregated from other funds except to the extent required by law) and (iii) may consult with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it in good faith in reliance upon the advice or opinion of such counsel. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act.

(l) Neither the Collateral Agent nor the Trustee shall be liable for delays or failures in performance resulting from acts beyond its control. Such acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes or other disasters. Neither the Collateral Agent nor the Trustee shall be liable for any indirect, special, punitive, incidental or consequential damages (included but not limited to lost profits) whatsoever, even if it has been informed of the likelihood thereof and regardless of the form of action.

(m) The Collateral Agent does not assume any responsibility for any failure or delay in performance or any breach by the Issuer or any other Grantor under this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents. The Collateral Agent shall not be responsible to the Holders or any other Person for any recitals, statements, information, representations or warranties contained in this Indenture, the Note Security Documents, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) or in any certificate, report, statement, or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if

139

applicable) or any Note Security Document; the execution, validity, genuineness, effectiveness or enforceability of the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and any Note Security Documents of any other party thereto; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any Collateral, or the validity, effectiveness, enforceability, sufficiency, extent, perfection or priority of any Lien therein; the validity, enforceability or collectability of any Obligations; the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any obligor; or for any failure of any obligor to perform its Obligations under this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents. The Collateral Agent shall have no obligation to any Holder or any other Person to ascertain or inquire into the existence of any Default or Event of Default, the observance or performance by any obligor of any terms of this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents, or the satisfaction of any conditions precedent contained in this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and any Note Security Documents. The Collateral Agent shall not be required to initiate or conduct any litigation or collection or other proceeding under this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents unless expressly set forth hereunder or thereunder. The Collateral Agent shall have the right at any time to seek instructions from the Holders (with indemnities) with respect to the administration of this Indenture, the Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement (if applicable).

(n) The parties hereto and the Holders hereby agree and acknowledge that neither the Collateral Agent nor the Trustee shall assume, be responsible for or otherwise be obligated for any liabilities, claims, causes of action, suits, losses, allegations, requests, demands, penalties, fines, settlements, damages (including foreseeable and unforeseeable), judgments, expenses and costs (including but not limited to, any remediation, corrective action, response, removal or remedial action, or investigation, operations and maintenance or monitoring costs, for personal injury or property damages, real or personal) of any kind whatsoever, pursuant to any environmental law as a result of this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable), the Note Security Documents or any actions taken pursuant hereto or thereto. Further, the parties hereto and the Holders hereby agree and acknowledge that in the exercise of its rights under this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents, the Collateral Agent or the Trustee may hold or obtain indicia of ownership primarily to protect the security interest of the Collateral Agent or the Trustee in the Collateral and that any such actions taken by the Collateral Agent or the Trustee shall not be construed as or otherwise constitute any participation in the management of such Collateral. In the event that the Collateral Agent or the Trustee is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit of another, which in the Collateral Agent’s or the Trustee’s sole discretion may cause the Collateral Agent or the Trustee to be considered an “owner or operator” under the provisions of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), 42 U.S.C. §9601, et seq., or otherwise cause the Collateral Agent or the Trustee to incur liability under CERCLA or any other federal, state or local law, the Collateral Agent and the Trustee reserves the right, instead of taking such action, to either resign as the Collateral Agent or the

140

Trustee or arrange for the transfer of the title or control of the asset to a court-appointed receiver. Neither the Collateral Agent nor the Trustee shall be liable to the Issuer, the Company, the Guarantors or any other Person for any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of the Collateral Agent’s or the Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to the discharge, release or threatened release of hazardous materials into the environment. If at any time it is necessary or advisable for property to be possessed, owned, operated or managed by any Person (including the Collateral Agent or the Trustee) other than the Issuer or the Guarantors, subject to the terms of the Note Security Documents, a majority in interest of Holders shall direct the Collateral Agent or the Trustee to appoint an appropriately qualified Person (excluding the Collateral Agent or the Trustee) who they shall designate to possess, own, operate or manage, as the case may be, the property.

(o) Subject to the provisions of the applicable Note Security Documents, the Intercreditor Agreement and the Third Lien Intercreditor Agreement, each Holder, by acceptance of the Notes, agrees that the Collateral Agent shall execute and deliver the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) and the Note Security Documents to which it is a party and all agreements, documents and instruments incidental thereto, and act in accordance with the terms thereof. For the avoidance of doubt, except as otherwise provided in the Note Security Documents, the Collateral Agent shall have no discretion under this Indenture, the Intercreditor Agreement, the Third Lien Intercreditor Agreement (if applicable) or the Note Security Documents and shall not be required to make or give any determination, consent, approval, request or direction without the written direction of the Holders of a majority in aggregate principal amount of the then outstanding Notes or the Trustee, as applicable.

(p) After the occurrence and continuance of an Event of Default, the Trustee, acting in accordance with the terms of the Indenture at the direction of the Holders of a majority of the aggregate principal amount of the Notes then outstanding, may direct the Collateral Agent in connection with any action required or permitted by this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable).

(q) The Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders distributed under the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) and to the extent not prohibited under the Intercreditor Agreement, for turnover to the Trustee to make further distributions of such funds to itself, the Trustee and the Holders in accordance with the provisions of Section 6.10 and the other provisions of this Indenture.

(r) In each case that the Collateral Agent may or is required hereunder or under any Note Security Document, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) to take any action (an “Action”), including without limitation to make any determination, to give consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any Note Security Document, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable), the Collateral Agent may seek direction from the Holders of a majority in aggregate principal amount of the then

141

outstanding Notes. The Collateral Agent shall not be liable with respect to any Action taken or omitted to be taken by it in accordance with the direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. If the Collateral Agent shall request direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes with respect to any Action, the Collateral Agent shall be entitled to refrain from such Action unless and until the Collateral Agent shall have received direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes, and the Collateral Agent shall not incur liability to any Person by reason of so refraining.

(s) Notwithstanding anything to the contrary in this Indenture or in any Note Security Document, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable), in no event shall the Collateral Agent or the Trustee be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture, the Note Security Documents, the Intercreditor Agreement or the Third Lien Intercreditor Agreement (if applicable) (including without limitation the filing or continuation of any Uniform Commercial Code or PPSA financing or continuation statements or similar documents or instruments), nor shall the Collateral Agent or the Trustee be responsible for, and neither the Collateral Agent nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Note Security Documents or the security interests or Liens intended to be created thereby.

(t) Before the Collateral Agent acts or refrains from acting in each case at the request or direction of the Issuer or the Guarantors, it may require an Officers’ Certificate and an Opinion of Counsel, which shall conform to the provisions of Section 12.5. The Collateral Agent shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion.

(u) Notwithstanding anything to the contrary contained herein but subject to the Note Security Documents, the Collateral Agent shall act pursuant to the instructions of the Holders and the Trustee solely with respect to the Note Security Documents and the Collateral.

(v) The Collateral Agent, in executing and performing its duties under the Note Security Documents, shall be entitled to all of the rights, protections, immunities and indemnities granted to it hereunder.

(w) The Issuer and each Guarantor, jointly and severally, will pay to the Collateral Agent such compensation, reimburse the Collateral Agent for expenses, and indemnify the Collateral Agent, all as set forth in Section 7.7 hereof (as though references to the Trustee therein were references to the Collateral Agent).

[FORM OF REVERSE SIDE OF NOTE]

ULTRA RESOURCES, INC.

9.00% Cash / 2.00% PIK Senior Secured Second Lien Notes due 2024

Ultra Resources, Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Issuer”), promises to pay interest on the principal amount of this Note (including any PIK Notes and increases in principal amount as a result of the payment of PIK Interest) at the rate per annum shown above.

The Issuer will pay interest semiannually on January 15 and July 15 of each year commencing July 15, 2019. Interest on the Notes will accrue from the most recent date to which interest has been paid on the Notes or, if no interest has been paid, from December 21, 2018. The Issuer shall pay interest on overdue principal, and on overdue premium (plus interest on such interest to the extent lawful), at the rate borne by the Notes to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Issuer shall pay Additional Amounts or Reimbursement Payments with respect to payments on the Notes in the circumstances set forth in Section 2.18 of the Indenture.

Interest on the Notes will accrue at (1) the annual rate of 9.00% and be payable in cash (“Cash Interest”), and (2) an annual rate of 2.00% (the “PIK Interest”) payable by increasing the principal amount of the outstanding Notes represented by one or more book entry Notes or Global Notes or, with respect to Notes represented by individual certificates, if any, by issuing additional “PIK Notes” in certificated form, in each case by rounding up to the nearest $1.00.

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

By no later than 11:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Note is due and payable, the Issuer shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal, premium, if any, and/or interest. The Issuer will pay interest (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the January 1 and July 1 next preceding the interest payment date even if Notes are cancelled, repurchased or redeemed after the record date and on or before the interest payment date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer will pay principal, premium, if any, and interest in

A-3

money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Notes represented by a Global Note (including principal, premium, if any, and interest) will be made by the transfer of immediately available funds to the accounts specified by The Depository Trust Company or any successor depository. The Issuer will make all payments in respect of a Definitive Note (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof.

Initially, Wilmington Trust, National Association, as trustee (the “Trustee”) will act as Trustee, Paying Agent and Registrar. The Issuer may appoint and change any Paying Agent, Registrar or co-registrar without notice to any Noteholder. The Parent Guarantor or any of its wholly-owned Restricted Subsidiaries organized in the United States may act as Paying Agent or Registrar.

At all times, PIK Interest on Notes will be payable, without the consent of the Holders: (i) with respect to book entry Notes or Notes represented by one or more Global Notes registered in the name of, or held by, DTC (or any successor depositary) or its nominee on the relevant record date, by increasing the principal amount of the outstanding book entry Notes or Global Notes, effective as of the applicable interest payment date, by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest $1.00) (“PIK Payment”) and the Trustee shall, at the request and direction of the Issuer set forth in an Issuer Order, authenticate or increase the principal amount of the book entry Note or Global Notes by the amount of the PIK Payment and (ii) with respect to Notes represented by individual certificates, if any, by issuing PIK Notes in certificated form, dated as of the applicable interest payment date, in an aggregate principal amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest $1.00), and the Trustee shall, at the request and direction of the Issuer set forth in an Issuer Order, authenticate and deliver such PIK Notes in certificated form for original issuance to the Holders on the relevant record date, as shown by the records of the register of holders.

The Issuer issued the Notes under an Indenture dated as of December 21, 2018 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Issuer, the Guarantors, the Trustee and Wilmington Trust, National Association, as Collateral Agent. The terms of the Notes include those stated in the Indenture. The Issuer is not required to offer to exchange the Notes for notes registered under the Securities Act or otherwise register or qualify by prospectus the Notes for resale under the Securities Act. The Indenture will not be qualified under the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) (as in effect on the date of the Indenture, the “Act”). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all terms and provisions of the Indenture, and Noteholders are referred to the Indenture for a statement of those terms. In the event of a conflict between the terms of this Note and the Indenture, the terms of the Indenture shall govern and control.

A-4

The Notes are senior obligations of the Issuer. This Note is one of the Issuer’s 9.00% Cash / 2.00% PIK Senior Secured Second Lien Notes due 2024 referred to in the Indenture. The Notes include (i) $545,000,000 aggregate principal amount of the Issuer’s 9.00% Cash / 2.00% PIK Senior Secured Second Lien Notes due 2024 issued under the Indenture on December 21, 2018 (herein called “Initial Notes”), and (ii) if and when issued from time to time subsequent to December 21, 2018 in exchange for the Issuer’s 6.875% Senior Notes due 2022 in accordance with Section 3.3(b)(13), additional 9.00% Cash / 2.00% PIK Senior Secured Second Lien Notes due 2024 (the “Additional Notes”). The Indenture imposes certain limitations on the incurrence of indebtedness, the making of restricted payments, the sale of assets and subsidiary stock, the incurrence of certain liens, the entering into of affiliate transactions, the entering into of agreements that restrict distribution from certain restricted subsidiaries and the consummation of mergers and consolidations. The Indenture also imposes requirements with respect to the provision of financial information and the provision of guarantees of the Notes by certain subsidiaries.

The Initial Notes issued on the Issue Date, any Additional Notes, any PIK Notes and any increase in the aggregate principal amount of Notes to pay PIK Interest will be treated as a single class for all purposes under the Indenture.

To guarantee the due and punctual payment of the principal, premium, if any, and interest (including post-filing or post-petition interest) on the Notes and all other amounts payable by the Issuer under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors have unconditionally guaranteed (and future guarantors, together with the Guarantors, will unconditionally Guarantee), jointly and severally, such obligations on a senior basis pursuant to the terms of the Indenture.

Except as set forth below or in Section 3.9(i) or Section 5.9 of the Indenture, the Notes will not be redeemable at the option of the Issuer prior to December 21, 2021. On and after such date, the Notes will be redeemable, at the Issuer’s option, in whole or in part, at any time upon notice as provided in the Indenture, at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid Cash Interest together with an amount of cash equal to all accrued and unpaid PIK Interest on the Notes to be redeemed to, but excluding, the applicable Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on December 21 of the years set forth below:

In addition, at any time and from time to time on or prior to December 21, 2021, upon notice as provided in the Indenture, the Issuer may redeem in the aggregate up to 35% of the original principal amount of the Notes (calculated after giving effect to any issuance of Additional Notes and any increase in the aggregate principal amount of the Notes in connection

A-5

with PIK Payments and PIK Notes), but in an amount not greater than the Net Cash Proceeds of one or more Equity Offerings at a redemption price (expressed as a percentage of principal amount) of 111.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, that:

(1) at least 65% of the original principal amount of the Notes (calculated after giving effect to any issuance of Additional Notes and any increase in the aggregate principal amount of the Notes in connection with PIK Payments and PIK Notes) must remain outstanding after each such redemption; and

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

The amount of Net Cash Proceeds from an Equity Offering being used to effect any redemption of the Notes pursuant to the immediately preceding paragraph shall not exceed the aggregate Net Cash Proceeds from such Equity Offering.

In addition, at any time prior to December 21, 2021, upon notice as provided in the Indenture, the Issuer may redeem the Notes (which includes any Additional Notes and any increase in the aggregate principal amount of the Notes in connection with PIK Payments and PIK Notes, if any), in whole or in part, at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium, plus Cash Interest together with an amount of cash equal to all accrued and unpaid interest and PIK Interest on the Notes to be redeemed, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

“Applicable Premium” means, with respect to a Note on any Redemption Date, the greater of (i) 1.0% of the principal amount of such Note or (ii) the excess, if any, of (A) the present value at such time of (1) the redemption price of such Note on December 21, 2021 (such redemption price being described in the first paragraph of this paragraph 5) plus (2) all required interest payments (excluding accrued and unpaid interest to such Redemption Date) due on such Note through December 21, 2021, computed using a discount rate equal to the Treasury Rate with respect to such Redemption Date plus 50 basis points discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day calendar months), over (B) the principal amount of such Note. The Trustee shall have no duty to calculate or verify the calculation of the Applicable Premium.

“Treasury Rate” means, with respect to any Redemption Date, 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) which has become publicly available at least two Business Days prior to the Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the Redemption Date to December 21, 2021; provided, however, that if the period from the Redemption Date to December 21, 2021 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

A-6

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 December 21, 2021 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.

The Issuer will (a) calculate the Treasury Rate as of a date no later than the second Business Day preceding the applicable Redemption Date and (b) prior to such Redemption Date file with the Trustee an Officers’ Certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable detail.

The Notes are also subject to tax redemption at the Issuer’s option as set forth in Section 5.9 of the Indenture.

The Notes may be the subject of a Change of Control Offer and/or an Asset Disposition Offer, as further described in the Indenture. The Issuer shall not be required to make any mandatory redemptions or sinking fund payments with respect to the Notes.

The Notes are in registered form without coupons in minimum denominations of principal amount of $2,000 and whole multiples of $1.00 in excess thereof (or minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof after a PIK Payment). A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any taxes and fees required by law or permitted by the Indenture. The Issuer or the Registrar need not register the transfer of or exchange any Note (A) for a period (1) of 15 days before a selection of Notes to be redeemed or (2) beginning 15 days before an interest payment date and ending on such interest payment date or (B) selected for redemption, except the unredeemed portion of any Note being redeemed in part.

The registered Holder of this Note shall be treated as the owner of it for all purposes.

The Indenture, the Notes and the related Guarantees may be amended or supplemented as provided in the Indenture.

The Events of Default relating to the Notes are defined in Section 6.1 of the Indenture. Upon the occurrence of an Event of Default relating to the Notes, the rights and obligations of the Issuer, the Guarantors, the Trustee and the Holders shall be as set forth in the applicable provisions in the Indenture.

(c) The Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, agrees that neither the Third Lien Collateral [Agent][Trustee] nor any other Third Lien Party will take any action that would hinder any exercise of remedies (including an Enforcement Action) undertaken by any Priority Agent or any other Priority Secured Party with respect to the Shared Collateral, including any sale, lease, exchange, transfer or other disposition of the Shared Collateral, whether by foreclosure or otherwise, and (ii) hereby waives any and all rights it or any Third Lien Party may have as a junior lien creditor or otherwise to object to the manner in which any Priority Agent or the other Priority Secured Parties seek to enforce or collect the Priority Obligations or the Liens granted on any of the First Lien Collateral or Second Lien Collateral, as applicable, regardless of whether any action or failure to act by or on behalf of any Priority Agent or any other Priority Secured Party is adverse to the interests of the Third Lien Parties.

-15-

(d) The Third Lien Collateral [Agent][Trustee] hereby acknowledges and agrees that no covenant, agreement or restriction contained in any Third Lien Debt Document shall be deemed to restrict in any way the rights and remedies of any Priority Agent or the other Priority Secured Parties with respect to the First Lien Collateral or Second Lien Collateral, as applicable, as set forth in this Agreement and the Priority Debt Documents.

(e) Subject to clause (F) of the proviso in Section 3.01(a)(ii), the Priority Agents shall have the exclusive right to exercise any right or remedy with respect to the Shared Collateral and shall have the exclusive right to determine and direct the time, method and place for exercising such right or remedy or conducting any proceeding with respect thereto.

Section 3.02 [Reserved].

Section 3.03 Actions upon Breach. Should the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party, contrary to this Agreement, in any way take, attempt to take or threaten to take any action with respect to the Shared Collateral (including any attempt to realize upon or enforce any remedy with respect to this Agreement) or fail to take any action required by this Agreement, any Priority Agent or other Priority Secured Party (in its or their own name or in the name of the Borrower or any other Grantor) or the Borrower or any other Grantor may obtain relief against the Third Lien Collateral [Agent][Trustee] or such other Third Lien Party by injunction, specific performance or other appropriate equitable relief. The Third Lien Collateral [Agent][Trustee], on behalf of itself and each other Third Lien Party, hereby (i) agrees that the Priority Secured Parties’ damages from the actions of the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party may at that time be difficult to ascertain and may be irreparable and waives any defense that the Priority Secured Parties cannot demonstrate damage or be made whole by the awarding of damages, (ii) agrees that the Borrower’s and the other Grantors’ damages from the actions of the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party may at that time be difficult to ascertain and may be irreparable and waives any defense that the Borrower or any other Grantor cannot demonstrate damage or be made whole by the awarding of damages, and (iii) irrevocably waives any defense based on the adequacy of a remedy at law and any other defense that might be asserted to bar the remedy of specific performance in any action that may be brought by any Priority Agent, any other Priority Secured Party, or the Borrower or any other Grantor.

Payments

Section 4.01 Application of Proceeds. After an event of default under any Priority Debt Document has occurred and until such event of default is cured or waived, so long as the Discharge of Priority Obligations has not occurred and regardless of whether an Insolvency or Liquidation Proceeding has been commenced, the Shared Collateral or Proceeds thereof received in connection with the sale or other disposition of, or collection on, such Shared Collateral or upon the exercise of any other remedies (including an Enforcement Action) shall be applied by the Designated Priority Agent to the Priority Obligations in such order as specified in the relevant Priority Debt Documents until the Discharge of Priority Obligations has occurred. Upon the Discharge of Priority Obligations, the Designated Priority Agent shall deliver promptly to the Third Lien Collateral [Agent][Trustee] any Shared Collateral or Proceeds thereof held by it in the same form as received, with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct, to be applied by the Third Lien Collateral [Agent][Trustee] to the Third Lien Obligations in such order as specified in the relevant Third Lien Debt Documents until the Third Lien Obligations have been paid in full in cash. Upon the payment in full in cash of the Third Lien Obligations, any Shared Collateral or Proceeds thereof shall be distributed to the relevant Grantor or, to the extent directed by such Grantor or a court of competent jurisdiction, to whomever may be lawfully entitled to receive the then remaining amount to be distributed.

Section 4.02 Payments Over. Subject to Section 6.03 hereof, unless and until the Discharge of Priority Obligations has occurred, (a) regardless of whether an Insolvency or Liquidation Proceeding has been commenced, any Shared Collateral or Proceeds thereof received by the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party in connection with the exercise of any right or remedy (including setoff) relating to the Shared Collateral, whether or not in contravention of this Agreement or otherwise, and (b) any distributions received by the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party with respect to its secured claims pursuant to an Insolvency or Liquidation Proceeding, shall, in the case of clauses (a) and (b), be segregated and held in trust for the benefit of and forthwith paid over to the Designated Priority Agent for the benefit of the Priority Secured Parties in the same form as received, with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct. The Designated Priority Agent is hereby authorized to make any such endorsements as agent for the Third Lien Collateral [Agent][Trustee] or any such other Third Lien Party. This authorization is coupled with an interest and is irrevocable. For the avoidance of doubt, this Agreement provides for Lien priorities as between the Priority Secured Parties with respect to the Priority Obligations, on the one hand, and the Third Lien Parties with respect to the Third Lien Obligations, on the other hand, and does not subordinate the Third Lien Obligations to the Priority Obligations in right of payment.

Section 5.03 Amendments to Debt Documents.

(a) The Priority Debt Documents may be amended, restated, amended and restated, supplemented, extended, renewed, replaced, restructured and/or otherwise modified in accordance with their terms and the Indebtedness under the Priority Facilities may be Refinanced or replaced, in whole or in part, in each case, without the consent of the Third Lien Parties, so long as not prohibited by the Third Lien Debt Documents in effect on the date hereof, all without affecting the Lien priorities provided for herein and the other provisions of this Agreement; ; provided, however, that, without the consent of the Majority Third Lien Parties, no such amendment, restatement, supplement, modification or Refinancing (or successive amendments, restatements, supplements, modifications or Refinancings) shall (i) contravene the provisions of this Agreement or (ii) solely to the extent that the stated maturity date of the Indebtedness outstanding under the Third Lien Debt Documents is earlier than the stated maturity date of the Priority Obligations, contractually restrict or otherwise directly and adversely affect the payment at or following (and, for the avoidance of doubt, solely at or following, and not prior to) the stated maturity date of the Indebtedness under the Third Lien Debt Agreement.

The Third Lien Collateral [Agent][Trustee] and the other Third Lien Parties may exercise their rights and remedies, if any, as unsecured creditors they may have against the Borrower and any other Grantor in accordance with the terms of the Third Lien Debt Documents and applicable law so long as such rights and remedies do not violate, or are not otherwise inconsistent with, any provision of this Agreement (it being understood that any express provision of this Agreement that requires any party hereto to act or refrain from acting shall be applicable to such party in its respective capacities as a secured creditor and as an unsecured creditor). Nothing in this Agreement shall prohibit the receipt by the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party of the required payments of principal, premium, interest, fees, indemnities, expenses and other amounts due under the Third Lien Debt Documents so long as such receipt is not the direct or indirect result of the exercise by a Third Lien Collateral [Agent][Trustee] or any other Third Lien Party of rights or remedies as a

-22-

secured creditor in respect of Shared Collateral in contravention of this Agreement or is not otherwise subject to turnover pursuant to Section 4.02 or Section 6.03. In the event the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party becomes a judgment lien creditor in respect of Shared Collateral as a result of its enforcement of its rights as an unsecured creditor in respect of Third Lien Obligations, such judgment lien shall be subordinated to the Liens securing Priority Obligations and any DIP Financing (and all obligations relating thereto) on the same basis as the other Liens securing the Third Lien Obligations are so subordinated to such Liens securing Priority Obligations under this Agreement. Nothing in this Agreement shall impair or otherwise adversely affect any rights or remedies the Priority Agents or the other Priority Secured Parties may have with respect to the First Lien Collateral or Second Lien Collateral, as applicable.

Section 5.05 Gratuitous Bailee for Perfection.

(a) Each Priority Agent acknowledge and agree that if it shall at any time hold a Lien securing any Priority Obligations on any Shared Collateral (including for avoidance of doubt, deposit accounts subject to control agreements) that can be perfected by the possession, control (including as defined in Section 9-104 of the UCC) or notation of such Shared Collateral or of any account in which such Shared Collateral is held, and if such Shared Collateral or any such account is in fact in the possession or under the control of, or notated in the name of, such Priority Agent, or of agents or bailees of such Person (such Shared Collateral being referred to herein as the “Pledged or Controlled Collateral”), or if it shall at any time obtain any landlord waiver or bailee’s letter or any similar agreement or arrangement granting it rights or access to Shared Collateral, such Priority Agent shall also hold, control or notate such Pledged or Controlled Collateral, or take such actions with respect to such landlord waiver, bailee’s letter or similar agreement or arrangement, as sub-agent or gratuitous bailee for the Third Lien Collateral [Agent][Trustee], in each case solely for the purpose of perfecting the Liens granted under the Third Lien Collateral Documents or granting rights or access to any Shared Collateral subject to such landlord waiver or bailee’s letter or any similar agreement or arrangement and subject to the terms and conditions of this Section 5.05.

(b) Except as otherwise specifically provided herein, until the Discharge of Priority Obligations has occurred, the Priority Agents and the Priority Secured Parties shall be entitled to deal with the Pledged or Controlled Collateral in accordance with the terms of the Priority Debt Documents as if the Liens under the Third Lien Collateral Documents did not exist. The rights of the Third Lien Collateral [Agent][Trustee] and the other Third Lien Parties with respect to the Pledged or Controlled Collateral shall at all times be subject to the terms of this Agreement.

(c) The Priority Agents and the other Priority Secured Parties shall have no obligation whatsoever to the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party to assure that any of the Pledged or Controlled Collateral is genuine or owned by the Grantors or to protect or preserve rights or benefits of any Person or any rights pertaining to the Shared Collateral, except as expressly set forth in this Section 5.05. The duties or responsibilities of the Priority Agents under this Section 5.05 shall be limited solely to holding, controlling or being notated on the Shared Collateral and the related Liens referred to in paragraph (a) of this Section 5.05 as sub-agent and gratuitous bailee for the Third Lien Collateral [Agent][Trustee] for purposes of perfecting the Lien held by the Third Lien Collateral [Agent][Trustee] on behalf of the Third Lien Parties.

(d) No Priority Agent shall have, by reason of the Third Lien Collateral Documents or this Agreement, or any other document, a fiduciary relationship in respect of the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party, and the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, hereby waives and releases the Priority Agents from all claims and liabilities arising pursuant to the Priority Agents’ roles under this Section 5.05 as sub-agents and gratuitous bailees with respect to the Shared Collateral.

(e) Upon the Discharge of Priority Obligations, the Designated Priority Agent shall, at the Grantors’ sole cost and expense, (i)(A) deliver to the Third Lien Collateral [Agent][Trustee], to the extent that it is legally permitted to do so, all Shared Collateral, including all proceeds thereof, held or controlled by such Designated Priority Agent or any of its agents or bailees, including the transfer of possession and control, or the notation of, as applicable, of the Pledged or Controlled Collateral, together with any necessary endorsements or notices to depositary banks, securities intermediaries and commodities intermediaries, and assign its rights under any landlord waiver or bailee’s letter or any similar agreement or arrangement granting it rights in or access to Shared Collateral, or (B) direct and deliver such Shared Collateral as a court of competent jurisdiction may otherwise direct, (ii) notify any applicable insurance carrier that it is no longer entitled to be a loss payee or additional insured under the insurance policies of any Grantor issued by such insurance carrier and (iii) notify any governmental authority involved in any condemnation or similar proceeding involving any Grantor that the Third Lien Collateral [Agent][Trustee] is entitled to approve any awards granted in such proceeding. The Borrower and the other Grantors shall take such further action as is required to effectuate the transfer contemplated hereby and shall indemnify the Designated Priority Agent for any loss or damage suffered by the Designated Priority Agent as a result of such transfer, except for any loss or damage suffered by any such Person that is determined by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the bad faith, gross negligence or willful misconduct of such Person or (to the extent involved in or aware of such transfer) any of its Controlling Persons or Controlled Affiliates or any of the officers, directors, employees, partners or agents of any of the foregoing. The Designated Priority Agent shall have no obligations to follow instructions from the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party in contravention of this Agreement.

(f) None of the Priority Agents nor any of the other Priority Secured Parties shall be required to marshal any present or future collateral security for any obligations of the Borrower or any Subsidiary to the Priority Agent or any other Priority Secured Party under the Priority Debt Documents or any assurance of payment in respect thereof or to any Third Lien Party, or to resort to such collateral security or other assurances of payment in any particular order, and all of their rights in respect of such collateral security or any assurance of payment in respect thereof shall be cumulative and in addition to all other rights, however existing or arising. Without limiting any of the foregoing, the Third Lien Collateral [Agent][Trustee], on behalf of itself and each Third Lien Party, hereby agrees that it will not, and hereby waives any right to, assert any marshaling, appraisal, valuation or other similar right that may otherwise be available to a junior secured creditor.

Section 5.06 When Discharge of Priority Obligations Deemed To Not Have Occurred. If, at any time substantially concurrently with or after the occurrence of the Discharge of Priority Obligations, the Borrower or any Subsidiary consummates any Refinancing of or incurs any Priority Obligations, then such Discharge of Priority Obligations shall automatically be deemed not to have occurred for all purposes of this Agreement (other than with respect to any actions taken prior to the date of such consummation or incurrence as a result of the occurrence of such first Discharge of Priority Obligations) and the applicable agreement governing such Priority Obligations shall automatically be treated as a Priority Debt Document for all purposes of this Agreement, including for purposes of the Lien priorities and rights in respect of Shared Collateral set forth herein, and the agent, representative or trustee for the holders of such Priority Obligations shall be a Priority Agent for all purposes of this Agreement. Upon receipt of notice of such incurrence (including the identity of the new Priority Agent) from the Borrower and the new Priority Agent under the agreement governing such Priority Obligations, the Third Lien Collateral [Agent][Trustee] shall promptly (a) enter into such documents and agreements (at the expense of the Borrower), including amendments or supplements to this Agreement, as the Borrower or such new Priority Agent shall reasonably request in writing in order to provide the new Priority Agent the rights of a Priority Agent contemplated hereby, (b) deliver to such Priority Agent, to the extent that it is legally permitted to do so, all Shared Collateral, including all proceeds thereof, held or controlled by the Third Lien Collateral [Agent][Trustee] or any of its agents or bailees, including the transfer of possession and control, or the notation, as applicable, of the Pledged or Controlled Collateral, together with any necessary endorsements and notices to depositary banks, securities intermediaries and commodities intermediaries, and assign its rights under any landlord waiver or bailee’s letter or any similar agreement or arrangement granting it rights in or access to Shared Collateral, (c) notify any applicable insurance carrier that the new Priority Agent is entitled to be the loss payee or additional insured under the insurance policies of any Grantor issued by such insurance carrier and (d) notify any governmental authority involved in any condemnation or similar proceeding involving a Grantor that the new Priority Agent is entitled to approve any awards granted in such proceeding.

ARTICLE VI

Insolvency or Liquidation Proceedings

Section 6.01 Financing Issues. Until the Discharge of Priority Obligations has occurred, if the Borrower or any other Grantor shall be subject to any Insolvency or Liquidation Proceeding and any Priority Agent or any other Priority Secured Party shall consent (or not object) to the use of cash or the sale or use of other collateral or consent (or not object) to the Borrower’s or any other Grantor’s obtaining financing under Section 363 or Section 364 of the Bankruptcy Code or any similar provision of any other Bankruptcy Law (“DIP Financing”), then the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, agrees that it will raise no objection to and will not otherwise contest (a) such use of such cash or other collateral, unless the Priority Agents shall oppose or object to such use of cash collateral (in which case, no Third Lien Collateral [Agent][Trustee] nor any other Third Lien Party shall seek any relief in connection therewith that is inconsistent with the relief being sought by the Priority Secured Parties); (b) such DIP Financing, so long as the Third Lien Collateral [Agent][Trustee] retains its Liens on the Third Lien Collateral, for the benefit of the Third Lien Parties, with the same priority relative to the Priority Obligations as is set forth in Section 2.01, and, except to the extent permitted

-25-

by Section 6.03, will not request adequate protection or any other relief in connection therewith and, to the extent the Liens securing any Priority Obligations are subordinated to or pari passu with such DIP Financing, will subordinate (and will be deemed hereunder to have subordinated) its Liens in the Shared Collateral to (x) such DIP Financing (and all obligations relating thereto) on the same basis as the Liens securing the Third Lien Obligations are so subordinated to Liens securing Priority Obligations under this Agreement, (y) any adequate protection Liens provided to the Priority Secured Parties, and (z) any “carve-out” for professional and United States Trustee fees agreed to by the First Lien Collateral Agent; (c) any motion for relief from the automatic stay or from any injunction against foreclosure or enforcement in respect of Priority Obligations or the Shared Collateral made by any Priority Agent or any other Priority Secured Party; (d) any exercise by any Priority Secured Party of the right to credit bid Priority Obligations at any sale in foreclosure of Shared Collateral, First Lien Collateral and/or Second Lien Collateral or under Section 363(k) of the Bankruptcy Code or other applicable law; (e) any other request for judicial relief made in any court by any Priority Secured Party relating to the lawful enforcement of any Lien on First Lien Collateral or Second Lien Collateral; or (f) any order (including orders to retain professionals or set bid procedures) relating to a sale or other disposition of any Shared Collateral of any Grantor to which any Priority Agent has consented or not objected; provided that (1) the Liens securing the Priority Obligations and the Third Lien Obligations will attach to the Proceeds of the sale or other disposition on the same basis of priority as the Liens on the Shared Collateral securing the Priority Obligations rank to the Liens on the Shared Collateral securing the Third Lien Obligations pursuant to this Agreement and (2) in the event that the proceeds of any such sale or other disposition shall not be applied (to the extent applicable) in accordance with Section 4.01 or to permanently reduce the obligations owing pursuant to any DIP Financing, the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, may object to or contest such use of proceeds to the extent applied other than in accordance with Section 4.01 or to permanently reduce the obligations owing pursuant to any DIP Financing (but not, for the avoidance of doubt, to such sale or disposition itself); provided, however, that the Third Lien Parties are not deemed to have waived any rights to credit bid on the Shared Collateral in any such sale or disposition in accordance with Section 363(k) of the Bankruptcy Code (or any similar provision under any other applicable Bankruptcy Law), so long as any such credit bid provides for Discharge of Priority Obligations (including the payment in full in cash of the Priority Obligations) concurrently with the consummation of such credit bid. The Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, agrees that notice received two Business Days prior to the entry of an order approving such usage of cash or other collateral or approving such DIP Financing shall be adequate notice. Notwithstanding anything herein to the contrary, neither the Third Lien Collateral [Agent][Trustee] or any Third Lien Party may provide or offer to provide any DIP Financing unless (x) in the case of any such DIP Financing that is secured by Liens on the Shared Collateral senior or pari passu with the Liens on the Shared Collateral securing the Priority Obligations, such DIP Financing shall result in the Discharge of Priority Obligations substantially concurrently with the making or funding of the initial extensions of credit thereunder and/or (y) in the case of any such DIP Financing secured by Liens on the Shared Collateral that are junior and subordinated to the Liens on the Shared Collateral securing the Priority Obligations, none of the Priority Secured Parties are providing or have offered to provide, or have consented to any third-party providing, any DIP Financing (and any such DIP Financing provided by such Third Lien Parties shall otherwise be treated as Third Lien Obligations for purposes of this Agreement).

-26-

Section 6.02 Relief from the Automatic Stay. Until the Discharge of Priority Obligations has occurred, the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, agrees that none of them shall seek relief from the automatic stay or any other stay in any Insolvency or Liquidation Proceeding or take any action in derogation thereof, in each case in respect of any Shared Collateral, without the prior written consent of the Priority Agents; provided that in the event that the Priority Agents, for themselves and on behalf of the other Priority Secured Parties, are granted relief from the automatic stay or any other such stay, then the Third Lien Collateral [Agent][Trustee], for itself and on behalf of the other Third Lien Parties, may seek relief from such stay, solely on terms substantially identical to those granted to the Priority Agents and subject to the terms of this Agreement (including without limitation, Section 3.01(a)).

Section 6.03 Adequate Protection. The Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, agrees that none of them shall (A) object, contest or support any other Person objecting to or contesting (a) any request by any Priority Agent or any other Priority Secured Parties for adequate protection in any form, (b) any objection by any Priority Agent or any other Priority Secured Parties to any motion, relief, action or proceeding based on such Priority Agent’s or other Priority Secured Party’s claiming a lack of adequate protection or (c) the payment of interest, fees, expenses or other amounts of any Priority Agent or any other Priority Secured Party as adequate protection or otherwise under Section 506(b) of the Bankruptcy Code or any similar provision of any other Bankruptcy Law or (B) assert or support any claim for costs or expenses of preserving or disposing of any Shared Collateral under Section 506(c) of the Bankruptcy Code or any similar provision of any other Bankruptcy Law. Notwithstanding anything contained in this Section 6.03 or in Section 6.01, in any Insolvency or Liquidation Proceeding, (i) if the Priority Secured Parties (or any subset thereof) are granted adequate protection in the form of additional or replacement collateral or superpriority claims in connection with any DIP Financing or use of cash collateral under Section 363 or 364 of the Bankruptcy Code or any similar provision of any other Bankruptcy Law, then the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, may seek or request adequate protection in the form of a Lien on such additional or replacement collateral and/or a superpriority claim (as applicable), which (A) Lien is subordinated to the Liens securing all Priority Obligations and all adequate protection Liens granted to the Priority Secured Parties, on the same basis as the other Liens securing the Third Lien Obligations are subordinated to the Liens securing Priority Obligations under this Agreement and/or (B) superpriority claim is subordinated to all superpriority claims of the Priority Secured Parties on the same basis as the other claims of the Third Lien Parties are subordinated to the claims of the Priority Secured Parties under this Agreement; provided that each Third Lien Party shall have irrevocably agreed, pursuant to Section 1129(a)(9) of the Bankruptcy Code in any stipulation and/or order granting such adequate protection, that such junior superpriority claims may be paid under any Plan of Reorganization in any combination of cash, debt, equity or other property having a value on the effective date of such plan equal to the allowed amount of such claims, (ii) in the event the Third Lien Collateral [Agent][Trustee], for itself and on behalf of the other Third Lien Parties, are granted adequate protection (in each instance, to the extent such grant is otherwise permissible under the terms and conditions of this Agreement) in the form of a Lien on additional or replacement collateral, then the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, agree that each Priority Agent shall also be granted a senior Lien on such additional or replacement collateral as adequate protection and security for the Priority

-27-

Obligations and that any Lien on such additional or replacement collateral securing and granted as adequate protection with respect to the Third Lien Obligations shall be subordinated to the Liens on such collateral securing the Priority Obligations and any other Liens granted to the Priority Secured Parties as adequate protection on the same basis as the other Liens securing the Third Lien Obligations are subordinated to such Liens securing Priority Obligations under this Agreement (and, to the extent the Priority Secured Parties are not granted such adequate protection in such form, any amounts recovered by or distributed to any Third Lien Party pursuant to or as a result of any Lien on such additional or replacement collateral so granted to the Third Lien Parties shall be subject to Section 4.02), and/or (iii) in the event the Third Lien Collateral [Agent][Trustee], for itself and on behalf of the other Third Lien Parties, are granted adequate protection (in each instance, to the extent such grant is otherwise permissible under the terms and conditions of this Agreement) in the form of a superpriority claim, then the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, agree that each Priority Agent shall also be granted adequate protection in the form of a superpriority claim, which superpriority claim shall be senior to the superpriority claim of the Third Lien Parties (and, to the extent the Priority Secured Parties are not granted such adequate protection in such form, any amounts recovered by or distributed to any Third Lien Party pursuant to or as a result of any such superpriority claim so granted to the Third Lien Parties shall be subject to Section 4.02). Without limiting the generality of the foregoing, to the extent that the Priority Secured Parties are granted adequate protection in the form of payments in the amount of current post-petition interest, fees and expenses, and/or other cash payments, then the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, shall not be prohibited from seeking and accepting adequate protection in the form of payments in the amount of current post-petition interest, incurred fees and expenses, and/or other cash payments (as applicable), subject to the right of the Priority Secured Parties to object to the reasonableness of the amounts of fees and expenses or other cash payments so sought by the Third Lien Parties; provided that if the Third Lien Parties received such adequate protection payments prior to the Discharge of Priority Obligations, then upon the effective date of any Plan of Reorganization or the conclusion or dismissal of the applicable Insolvency or Liquidation Proceeding, the Third Lien Parties shall turn over to the Designated Priority Agent (for application in accordance with Section 4.01) an amount equal to the lesser of (A) such adequate protection payments (other than on account of incurred legal fees and expenses) received by the Third Lien Parties and (B) the amount necessary to cause the Discharge of Priority Obligations, unless such Plan of Reorganization is proposed or supported by the number of Priority Secured Parties required under Section 1126(c) of the Bankruptcy Code.

Section 6.04 Preference Issues. If any Priority Secured Party is required in any Insolvency or Liquidation Proceeding or otherwise to disgorge, turn over or otherwise pay any amount to the estate of the Borrower or any other Grantor (or any trustee, receiver or similar Person therefor), because the payment of such amount was declared to be fraudulent or preferential in any respect or for any other reason, any amount (a “Recovery”), whether received as proceeds of security, enforcement of any right of setoff or otherwise, then the Priority Obligations shall be reinstated to the extent of such Recovery and deemed to be outstanding as if such payment had not occurred and the Priority Secured Parties shall be entitled to the benefits of this Agreement until a Discharge of Priority Obligations with respect to all such recovered amounts. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto. The Third Lien Collateral [Agent][Trustee], for itself

-28-

and on behalf of each other Third Lien Party, hereby agrees that none of them shall be entitled to benefit from any avoidance action affecting or otherwise relating to any distribution or allocation made in accordance with this Agreement, whether by preference or otherwise, it being understood and agreed that the benefit of such avoidance action otherwise allocable to them shall instead be allocated and turned over for application in accordance with the priorities set forth in this Agreement.

Section 6.05 Separate Grants of Security and Separate Classifications. The Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, acknowledges and agrees that (a) the grants of Liens pursuant to the Priority Collateral Documents and the Third Lien Collateral Documents constitute separate and distinct grants of Liens and (b) because of, among other things, their differing rights in the Shared Collateral, the Third Lien Obligations are fundamentally different from the Priority Obligations and must be separately classified in any Plan of Reorganization proposed, confirmed, or adopted in an Insolvency or Liquidation Proceeding. To further effectuate the intent of the parties as provided in the immediately preceding sentence, if it is held that any claims of the Priority Secured Parties and the Third Lien Parties in respect of the Shared Collateral constitute a single class of claims (rather than separate classes of senior and junior secured claims), then the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, hereby acknowledges and agrees that all distributions from the Shared Collateral shall be made as if there were separate classes of first lien, second lien and third lien secured claims against the Grantors in respect of the Shared Collateral, with the effect being that, to the extent that the aggregate value of the Shared Collateral is sufficient (for this purpose ignoring all claims held by the Third Lien Parties), the Priority Secured Parties shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest, fees, and expenses, and other claims, all amounts owing in respect of post-petition interest, fees, and expenses (whether or not allowed or allowable in any such Insolvency or Liquidation Proceeding) before any distribution from the Shared Collateral is made in respect of the Third Lien Obligations, and the Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, hereby acknowledges and agrees to turn over to the Designated Priority Agent amounts otherwise received or receivable by them from the Shared Collateral to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Third Lien Parties.

Section 6.06 No Waivers of Rights of Priority Secured Parties. Nothing contained herein shall, except as expressly provided herein, prohibit or in any way limit any Priority Agent or any other Priority Secured Party from objecting in any Insolvency or Liquidation Proceeding or otherwise to any action taken by any Third Lien Party, including the seeking by any Third Lien Party of adequate protection or the assertion by any Third Lien Party of any of its rights and remedies under the Third Lien Debt Documents or otherwise.

Section 6.07 Application. This Agreement, which the parties hereto expressly acknowledge is a “subordination agreement” under Section 510(a) of the Bankruptcy Code or any similar provision of any other Bankruptcy Law, shall be effective before, during and after the commencement of any Insolvency or Liquidation Proceeding. The relative rights set forth herein as to the Shared Collateral and proceeds thereof shall continue after the commencement of any Insolvency or Liquidation Proceeding on the same basis as prior to the date of the petition therefor, subject to any court order approving the financing of, or use of cash collateral by, any Grantor. All references herein to any Grantor shall include such Grantor as a debtor-in-possession and any receiver or trustee for such Grantor.

-29-

Section 6.08 Other Matters. To the extent that the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party has or acquires rights under Section 363 or Section 364 of the Bankruptcy Code or any similar provision of any other Bankruptcy Law with respect to any of the Shared Collateral, the Third Lien Collateral [Agent][Trustee], on behalf of itself and each other Third Lien Party, agrees not to assert any such rights, except as expressly provided in this Agreement, without the prior written consent of the Priority Agents, provided that if requested by the Designated Priority Agent, the Third Lien Collateral [Agent][Trustee] shall timely exercise such rights in the manner requested by the Designated Priority Agent, including any rights to payments in respect of such rights.

Section 6.09 506(c) Claims. Until the Discharge of Priority Obligations has occurred, the Third Lien Collateral [Agent][Trustee], on behalf of itself and each other Third Lien Party, agrees that it will not assert or enforce any claim under Section 506(c) of the Bankruptcy Code or any similar provision of any other Bankruptcy Law senior to or on a parity with the Liens securing the Priority Obligations for costs or expenses of preserving or disposing of any Shared Collateral.

Section 6.10 Reorganization Securities.

(a) If, in any Insolvency or Liquidation Proceeding, debt obligations of the reorganized debtor secured by Liens upon any property of the reorganized debtor are distributed, pursuant to a Plan of Reorganization, on account of both the Priority Obligations and the Third Lien Obligations, then, to the extent the debt obligations distributed on account of the Priority Obligations and on account of the Third Lien Obligations are secured by Liens upon the same assets or property, the provisions of this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations.

(b) No Third Lien Party (whether in the capacity of a secured creditor or an unsecured creditor) shall propose, vote in favor of, or otherwise directly or indirectly support any Plan of Reorganization that is inconsistent with the lien priorities set forth in this Agreement or any other provision of this Agreement unless any such Plan of Reorganization (i) results in the Discharge of Priority Obligations, including the repayment in cash, in full of the Priority Obligations (other than with respect to unasserted contingent indemnification obligations and contingent reimbursement obligations), by a date that is no later than the effective date of such Plan of Reorganization or (ii) is proposed or supported by the number of Priority Secured Parties required under Section 1126(c) of the Bankruptcy Code.

Section 6.11 Section 1111(b) of the Bankruptcy Code. The Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, shall not object to, oppose, support any objection to, or take any other action to impede, the right of any Priority Secured Party to make an election under Section 1111(b)(2) of the Bankruptcy Code. The Third Lien Collateral [Agent][Trustee], for itself and on behalf of each other Third Lien Party, waives any claim it may hereafter have against any senior claimholder arising out of the election by any Priority Secured Party of the application of Section 1111(b)(2) of the Bankruptcy Code.

-30-

Section 6.12 Post-Petition Interest.

(a) None of the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party shall oppose or seek to challenge any claim by any Priority Agent or any other Priority Secured Party for allowance in any Insolvency or Liquidation Proceeding of Priority Obligations consisting of claims for post-petition interest, fees, or expenses, under Section 506(b) of the Bankruptcy Code or otherwise (for this purpose ignoring all claims held by the Third Lien Parties).

(b) None of the Priority Agents or any or other Priority Secured Party shall oppose or seek to challenge any claim by the Third Lien Collateral [Agent] [Trustee] or any other Third Lien Party for allowance in any Insolvency or Liquidation Proceeding of Third Lien Obligations consisting of claims for post-petition interest, fees, or expenses, under Section 506(b) of the Bankruptcy Code or otherwise, to the extent of the value of the Lien of the Third Lien Collateral [Agent][Trustee] on behalf of the Third Lien Parties on the Shared Collateral (after taking into account the Priority Obligations).

ARTICLE VII

Reliance; Etc.

Section 7.01 Reliance. All loans and other extensions of credit made or deemed made on and after the date hereof by the Priority Secured Parties to the Borrower or any Subsidiary shall be deemed to have been given and made in reliance upon this Agreement. The Third Lien Collateral [Agent][Trustee], on behalf of itself and each other Third Lien Party, acknowledges that it and such other Third Lien Parties have, independently and without reliance on the Priority Agents or other Priority Secured Party, and based on documents and information deemed by them appropriate, made their own credit analysis and decision to enter into the Third Lien Debt Documents to which they are party or by which they are bound, this Agreement and the transactions contemplated hereby and thereby, and they will continue to make their own credit decisions in taking or not taking any action under the Third Lien Debt Documents or this Agreement; provided, that the foregoing shall not impose any obligation on the Second Lien Collateral Agent [and the Third Lien Collateral [Agent][Trustee]] to make any such credit analysis.

Section 7.02 No Warranties or Liability. The Third Lien Collateral [Agent][Trustee], on behalf of itself and each other Third Lien Party, acknowledges and agrees that no Priority Agent nor any other Priority Secured Party has made any express or implied representation or warranty, including with respect to the execution, validity, legality, completeness, collectability or enforceability of any of the Priority Debt Documents, the ownership of any Shared Collateral or the perfection or priority of any Liens thereon. The Priority Secured Parties will be entitled to manage and supervise their respective loans and extensions of credit under the Priority Debt Documents in accordance with law and as they may otherwise, in their sole discretion, deem appropriate, and the Priority Secured Parties may manage their loans and extensions of credit without regard to any rights or interests that the Third Lien Collateral

-31-

[Agent][Trustee] and the Third Lien Parties have in the Shared Collateral or otherwise, except as otherwise provided in this Agreement. No Priority Agent nor any other Priority Secured Party shall have any duty to the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party to act or refrain from acting in a manner that allows, or results in, the occurrence or continuance of an event of default or default under any agreement with the Borrower or any Subsidiary (including the Third Lien Debt Documents), regardless of any knowledge thereof that they may have or be charged with. Except as expressly set forth in this Agreement, the Priority Agents, the other Priority Secured Parties, the Third Lien Collateral [Agent][Trustee] and the other Third Lien Parties have not otherwise made to each other, nor do they hereby make to each other, any warranties, express or implied, nor do they assume any liability to each other with respect to (a) the enforceability, validity, value or collectability of any of the Priority Obligations, the Third Lien Obligations or any guarantee or security which may have been granted to any of them in connection therewith, (b) any Grantor’s title to or right to transfer any of the Shared Collateral or (c) any other matter except as expressly set forth in this Agreement.

Section 7.03 Obligations Unconditional. All rights, interests, agreements and obligations of the Priority Agents, the other Priority Secured Parties, the Third Lien Collateral [Agent][Trustee] and the other Third Lien Parties hereunder shall remain in full force and effect irrespective of:

(a) any lack of validity or enforceability of any Priority Debt Document or any Third Lien Debt Document;

(b) any change in the time, manner or place of payment of, or in any other terms of, all or any of the Priority Obligations or Third Lien Obligations, or any amendment or waiver or other modification, including any increase in the amount thereof, whether by course of conduct or otherwise, of the terms of the Priority Facilities or any other Priority Debt Document or of the terms of the Third Lien Debt Agreement or any other Third Lien Debt Document;

(c) any exchange of any security interest in any Shared Collateral or any other collateral or any amendment, waiver or other modification, whether in writing or by course of conduct or otherwise, of all or any of the Priority Obligations or Third Lien Obligations or any guarantee thereof;

(d) the commencement of any Insolvency or Liquidation Proceeding in respect of the Borrower or any other Grantor; or

(e) any other circumstances that otherwise might constitute a defense available to (i) the Borrower or any other Grantor in respect of the Priority Obligations (other than the Discharge of Priority Obligations subject to Sections 5.06 and 6.04) or (ii) the Third Lien Collateral [Agent][Trustee] or other Third Lien Party in respect of this Agreement.

ARTICLE VIII

Miscellaneous

Section 8.01 Conflicts. Subject to Section 8.22, in the event of any conflict between the provisions of this Agreement and the provisions of any Priority Debt Document or any Third Lien Debt Document, the provisions of this Agreement shall govern. Notwithstanding the foregoing, the relative rights and obligations of the Priority Agents and the other Priority Secured Parties (as amongst themselves) with respect to the Shared Collateral shall be governed by the terms of the First Lien/Second Lien Intercreditor Agreement and in the event of any conflict between the First Lien/Second Lien Intercreditor Agreement and this Agreement as to such relative rights and obligations, the provisions of this First Lien/Second Lien Intercreditor Agreement shall control.

Section 8.02 Continuing Nature of this Agreement; Severability. Subject to Section 6.04, this Agreement shall continue to be effective until the Discharge of Priority Obligations shall have occurred. This is a continuing agreement of Lien subordination, and the Priority Secured Parties may continue, at any time and without notice to the Third Lien Collateral [Agent][Trustee] or any other Third Lien Party, to extend credit and other financial accommodations and lend monies to or for the benefit of the Borrower or any Subsidiary constituting Priority Obligations in reliance hereon. The terms of this Agreement shall survive and continue in full force and effect in any Insolvency or Liquidation Proceeding. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

Section 8.03 Amendments; Waivers.

(a) No failure or delay on the part of any party hereto in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereto are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any party hereto in any case shall entitle such party to any other or further notice or demand in similar or other circumstances.

(b) This Agreement may be amended in writing signed by each Representative (in each case, acting in accordance with the documents governing the Revolving Credit Agreement, Term Loan Credit Agreement, the Second Lien Notes or the Third Lien Debt Agreement, as applicable) and the Borrower. Any such amendment, supplement or waiver shall be in writing and shall be binding upon the Priority Secured Parties, the Third Lien Parties and the Grantors and their respective successors and assigns[;provided that any such amendment, supplement or waiver which is materially adverse to the interests of the Borrower or which by the terms of this Agreement expressly requires the Borrower’s consent or which increases the obligations or reduces the rights of the Borrower or any Grantor, shall require the consent of the Borrower.]

-33-

Section 8.04 Information Concerning Financial Condition of the Borrower and the Subsidiaries.

Except as otherwise provided herein, all payments received by the Priority Secured Parties may be applied, reversed and reapplied, in whole or in part, to such part of the Priority Obligations as the Priority Secured Parties, in their sole discretion, deem appropriate and consistent and in accordance with the terms of the Priority Debt Documents. Except as otherwise provided herein, the Third Lien Collateral [Agent][Trustee], on behalf of itself and each other Third Lien Party, assents to any such extension or postponement of the time of payment of the Priority Obligations or any part thereof and to any other indulgence with respect thereto, to any substitution, exchange or release of any security that may at any time secure any part of the Priority Obligations and to the addition or release of any other Person primarily or secondarily liable therefor.

The execution and delivery of such instrument shall not require the consent of any other party hereunder, and will be acknowledged by the First Lien Collateral Agent, Second Lien Collateral Agent and Third Lien Collateral [Agent][Trustee].
