SECTION 1.1. Definitions.

“Acquired Indebtedness” means Indebtedness (i) of a Person or any of its Subsidiaries existing at the time such Person becomes or is merged with and into a Restricted Subsidiary or (ii) assumed in connection with the acquisition of assets from such Person, in each case whether or not Incurred by such Person in connection with, or in anticipation or contemplation of, such Person becoming a Restricted Subsidiary or such acquisition. Acquired Indebtedness shall be deemed to have been Incurred, with respect to clause (i) of the preceding sentence, on the date such Person becomes or is merged with and into a Restricted Subsidiary and, with respect to clause (ii) of the preceding sentence, on the date of consummation of such acquisition of assets.

“Additional Assets” means:

(1) any properties or assets (other than current assets) to be used by the Company or a Restricted Subsidiary in the Oil and Gas Business; or

(2) the Capital Stock of a Person that is or becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or a Restricted Subsidiary; provided, however, that such Restricted Subsidiary is primarily engaged in the Oil and Gas Business.

“Additional Interest” means the interest payable as a consequence of the failure to effectuate in a timely manner the exchange offer and/or shelf registration procedures set forth in the Registration Rights Agreement.

“Additional Securities” means any Securities (other than the Initial Securities or the Exchange Securities) issued under this Indenture in accordance with Section 2.2, as part of the same series as the Initial Securities to the extent outstanding and any Exchange Securities then outstanding.

“Adjusted Consolidated Net Tangible Assets” of the Company means (without duplication), as of the date of determination, the remainder of:

(a) the sum of:

(i) discounted future net revenues from proved oil and gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with SEC guidelines before any state or federal income taxes, as estimated by the Company in a reserve report prepared as of the end of the Company’s most recently completed fiscal year for which audited financial statements are available, or, at the Company’s option, the most recently completed fiscal quarter for which financial statements are available, in each case which reserve report is prepared, reviewed or audited by independent petroleum engineers, as increased by, as of the date of determination, the estimated discounted future net revenues from

(A) estimated proved oil and gas reserves acquired since such year end, which reserves were not reflected in such year end or quarterly reserve report, as applicable, and

(B) estimated oil and gas reserves attributable to extensions, discoveries and other additions and upward revisions of estimates of proved oil and gas reserves since such year end or quarterly reserve report, as applicable, due to exploration, development or exploitation, production or other activities, which would, in accordance with standard industry practice, cause such revisions (including the impact to proved reserves and future net revenues from estimated development costs incurred and the accretion of discount since such period end),

and decreased by, as of the date of determination, the estimated discounted future net revenues from

(D) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since such year end or quarter end, as applicable, due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated on a pre-tax basis and substantially in accordance with SEC guidelines,

in the case of clauses (A) through (D) calculated in accordance with SEC guidelines (using the prices and costs utilized in such year end or quarterly report, as applicable); provided, however, that in the case of each of the determinations made pursuant to clauses (A) through (D), such increases and decreases shall be as estimated by the Company’s petroleum engineers;

(ii) the capitalized costs that are attributable to Oil and Gas Properties of the Company and its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest available annual or quarterly financial statements;

-2-

(iii) the Net Working Capital of the Company and its Restricted Subsidiaries on a date no earlier than the date of the Company’s latest annual or quarterly financial statements; and

(iv) the greater of

(A) the net book value of other tangible assets of the Company and its Restricted Subsidiaries, as of a date no earlier than the date of the Company’s latest annual or quarterly financial statements, and

(B) the appraised value, as estimated by independent appraisers, of other tangible assets of the Company and its Restricted Subsidiaries, as of a date no earlier than the date of the Company’s latest quarterly or annual period for which financial statements are available; provided, that, if no such appraisal has been performed the Company shall not be required to obtain such an appraisal and only clause (iv)(A) of this definition shall apply;

minus

(b) the sum of:

(i) Minority Interests;

(ii) any net gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest annual or quarterly balance sheet (to the extent not deducted in calculating Net Working Capital of the Company in accordance with clause (a)(iii) above of this definition);

(iii) to the extent included in (a)(i) above, the discounted future net revenues, calculated in accordance with SEC guidelines (but utilizing prices and costs used in such year end or quarterly report, as applicable), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and

(iv) the discounted future net revenues, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in (a)(i) above, would be necessary to fully satisfy the payment obligations of the Company and its Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with respect thereto).

If the Company changes its method of accounting from the successful efforts method of accounting to the full cost or a similar method, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Company were still using the successful efforts method of accounting.

Such present value shall be calculated using a discount rate equal to the rate of interest implicit in such transaction, determined in accordance with GAAP; provided, however, that if such sale and leaseback transaction results in a Capitalized Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of “Capitalized Lease Obligation.”

“Average Life” means, as of the date of determination, with respect to any Indebtedness or Preferred Stock, the quotient obtained by dividing (1) the sum of the products of the numbers of years from the date of determination to the dates of each successive scheduled principal payment of such Indebtedness or redemption or similar payment with respect to such Preferred Stock multiplied by the amount of such payment by (2) the sum of all such payments.

Notwithstanding the preceding, a conversion (whether by merger, statutory conversion or otherwise) of the Company from a limited partnership to a limited liability company or corporation or an exchange of all of the outstanding partnership interests in the Company for Capital Stock in a corporation or a limited liability company, shall not constitute a Change of Control, so long as following such conversion or exchange the “persons” (as that term is used in Section 13(d)(3) of the Exchange Act) who Beneficially Owned the Capital Stock of the General Partner and the Company immediately prior to such transactions continue to Beneficially Own in the aggregate sufficient Capital Stock of such successor entity to elect a majority of its directors, managers trustees or other persons serving in a similar capacity for such successor entity.

“Company” has the meaning ascribed to it in the first introductory paragraph of this Indenture, together with its successors and assigns.

“Consolidated Coverage Ratio” means, for any Person, as of any date of determination, the ratio of (x) the aggregate amount of Consolidated EBITDAX of such Person for the period of the most recent four consecutive fiscal quarters ending prior to the date of such determination for which financial statements are in existence to (y) Consolidated Interest Expense for such four fiscal quarters, provided, however, that:

(1) if the Company or any Restricted Subsidiary:

-8-

(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 the Incurrence of 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 any revolving credit Indebtedness 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 during which such Indebtedness was outstanding or (ii) if such revolving credit Indebtedness was Incurred after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of Incurrence of such revolving credit Indebtedness to the date of such calculation, in each case, provided that such average daily balance shall take into account any permanent repayment of such revolving credit Indebtedness 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 any revolving credit Indebtedness, unless such revolving credit 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 Company 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 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 Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company 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 Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

-9-

(3) if, since the beginning of such period, the Company 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 Company or a Restricted Subsidiary) or an acquisition (or has 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 Company 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 Company 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 on behalf of the Company in good faith by a responsible financial or accounting officer of the Company; provided that such officer may in his or her discretion include any reasonably identifiable and factually supportable pro forma changes to Consolidated EBITDAX, including any pro forma expenses and cost reductions, that have occurred or in the judgment of such officer are reasonably expected to occur within 12 months of the date of the applicable transaction (regardless of whether such expense or cost reduction or any other operating improvements could then be reflected properly in pro forma financial statements prepared in accordance with Regulation S-X under the Securities Act or any other regulation or policy of the SEC). 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 Company or any Restricted Subsidiary, the interest rate shall be calculated by applying such optional rate chosen by the Company or such Restricted Subsidiary.

THE SECURITIES

SECTION 2.1. Form, Dating and Terms.

(a) The aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is unlimited, subject to compliance with the other terms of this Indenture. The Initial Securities issued on the date hereof shall be in an aggregate principal amount of $500,000,000. In addition, the Issuers may issue, from time to time in accordance with the provisions of this Indenture, including Section 3.2 hereof, Additional Securities (as provided herein) and Exchange Securities. Furthermore, Securities may be authenticated and delivered upon registration of transfer, exchange or in lieu of, other Securities pursuant to Section 2.2, 2.6, 2.10, 2.12, 5.8 or 9.5, in connection with an Asset Disposition Offer pursuant to Section 3.5 or in connection with a Change of Control Offer pursuant to Section 3.9.

-39-

The Securities shall be known and designated as “7.875% Senior Notes due 2024” of the Issuers.

With respect to any Additional Securities, the Issuers shall set forth in (a) a Board Resolution and (b) (i) an Officers’ Certificate or (ii) one or more indentures supplemental hereto, the following information:

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

(2) the issue price and the issue date of such Additional Securities, including the date from which interest shall accrue; and

(3) whether such Additional Securities shall be Restricted Securities issued in the form of Exhibit A hereto.

In authenticating and delivering Additional Securities, the Trustee shall be entitled to receive and shall be fully protected in relying upon, in addition to the Opinion of Counsel and Officers’ Certificate required by Section 11.4, an Opinion of Counsel as to the due authorization, execution, delivery, validity and enforceability of such Additional Securities.

The Initial Securities, the Additional Securities and the Exchange Securities shall be considered collectively as a single class for all purposes of this Indenture. Holders of the Initial Securities, the Additional Securities and the Exchange Securities will vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Initial Securities, the Additional Securities or the Exchange Securities shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

If any of the terms of any Additional Securities are established by action taken pursuant to Board Resolutions of the Issuers, a copy of an appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of the Issuers and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or the indenture supplemental hereto setting forth the terms of the Additional Securities.

(b) The Initial Securities are being offered and sold by the Issuers pursuant to a Purchase Agreement, dated December 2, 2016, among the Issuers, the Subsidiary Guarantors and the Initial Purchasers. The Initial Securities and any Additional Securities (if issued as Restricted Securities) (the “Additional Restricted Securities”) shall be resold initially only to (A) QIBs in reliance on Rule 144A and (B) Non-U.S. Persons in reliance on Regulation S. Such Initial Securities and Additional Restricted Securities may thereafter be transferred to, among others, QIBs and purchasers in reliance on Regulation S, in each case, in accordance with the procedure described herein. Additional Securities offered after the date hereof may be offered and sold by the Issuers from time to time pursuant to one or more purchase agreements in accordance with applicable law.

-40-

Initial Securities and Additional Restricted Securities offered and sold to QIBs in the United States of America in reliance on Rule 144A (the “Rule 144A Notes”) shall be issued in the form of a permanent global Security substantially in the form of Exhibit A, which is hereby incorporated by reference and made a part of this Indenture, including appropriate legends as set forth in Section 2.1(d) (the “Rule 144A Global Note”), deposited with the Trustee, as Securities Custodian, duly executed by the Issuers and authenticated by the Trustee as hereinafter provided. The Rule 144A Global Note may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate. The aggregate principal amount of the Rule 144A Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as Securities Custodian, as hereinafter provided.

Initial Securities and any Additional Restricted Securities offered and sold outside the United States of America (the “Regulation S Notes”) in reliance on Regulation S shall initially be issued in the form of a temporary global Security (the “Temporary Regulation S Global Note”), without interest coupons. Beneficial interests in the Temporary Regulation S Global Note will be exchanged for beneficial interests in a corresponding permanent global Security, without interest coupons, substantially in the form of Exhibit A including appropriate legends as set forth in Section 2.1(d) (the “Permanent Regulation S Global Note” and, together with the Temporary Regulation S Global Note, each a “Regulation S Global Note”) within a reasonable period after the expiration of the Restricted Period (as defined below) upon delivery of the certification contemplated by Section 2.7. Each Regulation S Global Note will be deposited upon issuance with, or on behalf of, the Trustee as Securities Custodian in the manner described in this Article II for credit to the respective accounts of the purchasers (or to such other accounts as they may direct), including, but not limited to, accounts at Euroclear Bank S.A./N.V. (“Euroclear”) or Clearstream Banking, société anonyme (“Clearstream”). Prior to the 40th day after the later of the commencement of the offering of the Initial Securities and the Issue Date (such period through and including such 40th day, the “Restricted Period”), interests in the Temporary Regulation S Global Note may only be transferred to Non-U.S. Persons pursuant to Regulation S, unless exchanged for interests in another Global Security in accordance with the transfer and certification requirements described herein.

Following the Restricted Period, Investors may hold their interests in the Regulation S Global Note through organizations other than Euroclear or Clearstream that are participants in DTC’s system or directly through Euroclear or Clearstream, if they are participants in such systems, or indirectly through organizations which are participants in such systems.

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

Exchange Securities exchanged for interests in the Rule 144A Notes and the Regulation S Notes shall be issued in the form of a permanent global Security, substantially in the form of Exhibit A, which is hereby incorporated by reference and made a part of this

-41-

Indenture, deposited with the Trustee as hereinafter provided, including the appropriate legend set forth in Section 2.1(d) (the “Exchange Global Note”). The Exchange Global Note shall be deposited upon issuance with, or on behalf of, the Trustee as Securities Custodian, duly executed by the Issuers and authenticated by the Trustee as hereinafter provided. The Exchange Global Note may be represented by more than one certificate, if so required by DTC’s rules regarding the maximum principal amount to be represented by a single certificate.

The Rule 144A Global Note and the Regulation S Global Note and the Exchange Global Note are sometimes collectively herein referred to as the “Global Securities.”

The principal of (and premium, if any) and interest (including Additional Interest, if any) on the Securities shall be payable at the office or agency of the Issuers maintained for such purpose in The City of New York, and at such other office or agency of the Issuers as may be maintained for such purpose pursuant to Section 2.3; provided, however, that, at the option of the Issuers, each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Securities Register or (ii) wire transfer to an account located in the United States maintained by the payee, subject to the last sentence of this paragraph. Payments in respect of Securities represented by a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC. At the Issuers’ option, payments in respect of Securities represented by Definitive Securities (including principal, premium, if any, and interest) may be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if the Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage, in addition to those set forth on Exhibit A and in Section 2.1(d). The Issuers shall approve any notation, endorsement or legend on the Securities. Each Security shall be dated the date of its authentication, and the Trustee’s certificate of authentication shall be substantially in the form set forth on Exhibit A. The terms of the Securities set forth in Exhibit A are part of the terms of this Indenture and, to the extent applicable, the Issuers, the Subsidiary Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to be bound by such terms.

(c) Denominations. The Securities shall be issuable only in fully registered form, without coupons, and only in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

-42-

(d) Restrictive Legends. Unless and until (i) an Initial Security or an Additional Security issued as a Restricted Security is sold under an effective registration statement or (ii) an Initial Security or an Additional Security issued as a Restricted Security is exchanged for an Exchange Security in connection with an effective registration statement, in each case pursuant to a Registration Rights Agreement or a similar agreement:

(1) the Rule 144A Global Note and the Regulation S Global Note shall bear the following legend on the face thereof:

THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS, EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) (A “QIB”) OR (B) IT IS NOT A U.S. PERSON, IS NOT ACQUIRING THIS NOTE FOR THE ACCOUNT OR BENEFIT OF A U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT, WITHIN THE TIME PERIOD REFERRED TO UNDER RULE 144 (TAKING INTO ACCOUNT THE PROVISIONS OF RULE 144(D) UNDER THE SECURITIES ACT, IF APPLICABLE) UNDER THE SECURITIES ACT AS IN EFFECT ON THE DATE OF THE TRANSFER OF THIS NOTE, RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) TO A PERSON WHOM THE HOLDER REASONABLY BELIEVES IS A QIB PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND, IN EACH CASE, IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE OR AN INTEREST HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER OF THIS NOTE OR ANY INTEREST HEREIN WITHIN THE TIME PERIOD REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

-43-

(2) the Temporary Regulation S Global Note shall bear the following additional legend on the face thereof:

THIS GLOBAL SECURITY IS A TEMPORARY GLOBAL NOTE FOR PURPOSES OF REGULATION S UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”). NEITHER THIS TEMPORARY GLOBAL NOTE NOR ANY INTEREST HEREIN MAY BE OFFERED, SOLD OR DELIVERED, EXCEPT AS PERMITTED UNDER THE INDENTURE REFERRED TO BELOW.

NO BENEFICIAL OWNERS OF THIS TEMPORARY GLOBAL NOTE SHALL BE ENTITLED TO RECEIVE PAYMENT OF PRINCIPAL OR INTEREST HEREON UNLESS THE REQUIRED CERTIFICATIONS HAVE BEEN DELIVERED PURSUANT TO THE TERMS OF THE INDENTURE.

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

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE ISSUERS OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO DTC, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

(e) Book-Entry Provisions. This Section 2.1(e) shall apply only to Global Securities deposited with the Trustee, as Securities Custodian.

(i) Each Global Security initially shall (x) be registered in the name of Cede & Co. as the nominee of DTC, (y) be delivered to the Trustee as Securities Custodian and (z) bear legends as set forth in Section 2.1(d). Transfers of a Global Security (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to DTC, its successors or their respective nominees, except as set forth in Section 2.1(e)(v) and 2.1(f). If a beneficial interest in a Global Security is transferred or exchanged for a beneficial interest in another Global Security, the Trustee will (x) record a decrease in the principal amount of the Global Security being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global Security.

-44-

Any beneficial interest in one Global Security that is transferred to a Person who takes delivery in the form of an interest in another Global Security, or exchanged for an interest in another Global Security, will, upon transfer or exchange, cease to be an interest in such Global Security and become an interest in the other Global Security and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

(ii) Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by DTC or by the Trustee as the Securities Custodian or under such Global Security, and DTC may be treated by the Issuers, the Subsidiary Guarantors, the Trustee and any agent of the Issuers, the Subsidiary Guarantors or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Subsidiary Guarantors, the Trustee or any agent of the Issuers, the Subsidiary Guarantors or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a Holder of a beneficial interest in any Global Security.

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

(iv) In connection with the transfer of an entire Global Security to beneficial owners pursuant to Section 2.1(f), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Issuers shall execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and make available for delivery, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations.

(v) The registered Holder of a Global Security may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

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

-45-

(f) Definitive Securities. Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Definitive Securities. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Definitive Securities in exchange for their beneficial interests in a Global Security upon written request in accordance with DTC’s and the Registrar’s procedures. In addition, Definitive Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if (A) DTC notifies the Issuers that it is unwilling or unable to continue as depositary for such Global Security or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Issuers within 90 days of such notice or (B) an Event of Default has occurred under this Indenture and is continuing and the Registrar has received a request from DTC to issue Securities in certificated registered form. 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 Securities 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).

(i) Any Definitive Security delivered in exchange for an interest in a Global Security pursuant to Section 2.1(e)(iv) shall, except as otherwise provided by Section 2.6(d), bear the applicable legend regarding transfer restrictions applicable to the Definitive Security set forth in Section 2.1(d).

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

(iii) If a Definitive Security is transferred or exchanged for another Definitive Security, (x) the Trustee will cancel the Definitive Security being transferred or exchanged, (y) the Issuers shall execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and make available for delivery, one or more new Definitive Securities in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Definitive Security (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Definitive Security, the Issuers shall execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and make available for delivery to the Holder thereof, one or more Definitive Securities in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Definitive Securities, registered in the name of the Holder thereof.

-46-

(iv) Notwithstanding anything to the contrary in this Indenture, in no event shall a Definitive Security be delivered upon exchange or transfer of a beneficial interest in the Temporary Regulation S Global Note prior to the end of the Restricted Period.

SECTION 2.2. Execution and Authentication. One Officer shall sign the Securities for the Issuers by manual or facsimile signature. If the Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

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

At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for delivery: (1) Initial Securities for original issue on the Issue Date in an aggregate principal amount of $500,000,000, (2) subject to the terms of this Indenture (including Section 3.2), Additional Securities for original issue in an unlimited principal amount, (3) Exchange Securities for issue only in an exchange offer pursuant to a Registration Rights Agreement or upon resale under an effective Shelf Registration Statement, and only in exchange for Initial Securities or Additional Securities of an equal principal amount and (4) when sold in connection with an effective registration statement, Initial Securities in the form of an Unrestricted Global Note, in each case upon a written order of the Issuers signed by one Officer of the Issuers (the “Issuer Order”). Such Issuer Order shall specify whether the Securities will be in the form of Definitive Securities or Global Securities, the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and whether the Securities are to be Initial Securities, Additional Securities or Exchange Securities.

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

In case the Issuers or any Subsidiary Guarantor, pursuant to Article IV or Section 10.2, as applicable, 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 Issuers or any Subsidiary 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 pursuant to Article IV or Section 10.2, as applicable, any of the Securities authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to

-47-

time, at the request of the successor Person, be exchanged for other Securities executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Securities surrendered for such exchange and of like principal amount; and the Trustee, upon receipt of an Issuer Order of the successor Person, shall authenticate and make available for delivery Securities as specified in such order for the purpose of such exchange. If Securities 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 Securities, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Securities at the time outstanding for Securities authenticated and delivered in such new name.

SECTION 2.3. Registrar and Paying Agent. The Issuers shall maintain in the continental United States an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”), and the Issuers shall maintain an office or agency (which, if the Notes are issued in certificated form shall be in New York, New York) where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange (the “Securities Register”). The Company or any of its Restricted Subsidiaries may act as Registrar or Paying Agent. The Issuers 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 Issuers shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuers shall notify the Trustee of the name and address of each such agent. If the Issuers fail 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 Issuers or any of its wholly owned Subsidiaries organized in the United States may act as Paying Agent, Registrar or transfer agent.

The Issuers initially appoint the Trustee as Registrar and Paying Agent for the Securities at its corporate trust office in Houston, Texas. The Issuers 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 Issuers 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 Issuers 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 Security is due and payable, the Issuers shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, premium or interest when due. The Issuers 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 Securityholders or the Trustee all money held by such Paying Agent for the payment of principal of, premium, if any, or interest on the Securities

-48-

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

SECTION 2.5. Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, or to the extent otherwise required under the TIA, the Issuers, 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 Securityholders and the Issuers shall otherwise comply with TIA § 312(a).

SECTION 2.6. Transfer and Exchange.

(a) A Holder may transfer a Security (or a beneficial interest therein) to another Person or exchange a Security (or a beneficial interest therein) for another Security or Securities 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 Security (or a beneficial interest therein) may only be made in accordance with this Section 2.6 and Section 2.1(e) and 2.1(f), as applicable, and, in the case of a Global Security (or a beneficial interest therein), the applicable rules and procedures of DTC, Euroclear and Clearstream. The Trustee shall refuse to register any requested transfer or exchange that does not comply with this paragraph.

SECTION 2.10. Mutilated, Destroyed, Lost or Stolen Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Issuers shall issue and the Trustee shall, upon receipt of an Issuer Order, authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Securityholder (a) satisfies the Issuers or the Trustee that such Security has been lost, destroyed or wrongfully taken within a reasonable time after such Securityholder 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 Issuers or Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee; provided, however, if after the delivery of such replacement Security, a protected purchaser of the Security for which such replacement Security was issued presents for payment or registration such replaced Security, the Trustee or the Issuers shall be entitled to recover such replacement Security 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 Issuers or the Trustee in connection therewith. If required by the Trustee or the Issuers, such Holder shall furnish an indemnity bond sufficient in the judgment of the Issuers and the Trustee to protect the Issuers, the Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Security is replaced, and, in the absence of notice to the Issuers, any Subsidiary Guarantor or the Trustee that such Security has been acquired by a protected purchaser, the Issuers shall execute, and upon receipt of an Issuer Order the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or wrongfully taken Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

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

Upon the issuance of any new Security under this Section 2.10, the Issuers 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.

-55-

Subject to the proviso in the initial paragraph of this Section 2.10, every new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or wrongfully taken Security shall constitute an original additional contractual obligation of the Issuers, any Subsidiary Guarantor and any other obligor upon the Securities, whether or not the mutilated, destroyed, lost or wrongfully taken Security 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 Securities 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 Securities.

SECTION 2.11. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding in the event the Issuers or an Affiliate of the Issuers holds the Security; provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the provisions of Section 11.6 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 Securities are present at a meeting of Holders of Securities 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 Securities which a Trust Officer of the Trustee actually knows to be held by the Issuers or an Affiliate of the Issuers shall not be considered outstanding.

If a Security is replaced pursuant to Section 2.10 (other than a mutilated Security surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuers receive proof satisfactory to them that the replaced Security is held by a protected purchaser. A mutilated Security ceases to be outstanding upon surrender of such Security 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 Securities (or portions thereof) to be redeemed or otherwise maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.12. Temporary Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Issuers may prepare and the Trustee shall, upon receipt of an Issuer Order, authenticate temporary Securities. Temporary Securities shall be substantially in the form, and shall carry all rights, of Definitive Securities but may have variations that the Issuers consider appropriate for temporary Securities. Without unreasonable delay, the Issuers shall prepare and the Trustee shall, upon receipt of an Issuer Order, authenticate Definitive Securities. After the preparation of Definitive Securities, the temporary Securities shall be exchangeable for Definitive Securities upon surrender of the temporary Securities at any office or agency maintained by the Issuers for

-56-

that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Issuers shall execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and make available for delivery in exchange therefor, one or more Definitive Securities representing an equal principal amount of Securities. Until so exchanged, the Holder of temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Securities.

SECTION 2.13. Cancellation. The Issuers at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and dispose of such Securities in accordance with its internal policies and customary procedures including delivery of a certificate describing such Securities disposed (subject to the record retention requirements of the Exchange Act) or deliver canceled Securities to the Issuers pursuant to written direction by one Officer of the Issuers. If the Issuers or any Subsidiary Guarantor acquires any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.13. The Issuers may not issue new Securities to replace Securities 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 Security have either been exchanged for Definitive Securities, transferred, redeemed, repurchased or canceled, such Global Security 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 Security is exchanged for Definitive Securities, transferred in exchange for an interest in another Global Security, redeemed, repurchased or canceled, the principal amount of Securities represented by such Global Security 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 Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

SECTION 2.14. Payment of Interest; Defaulted Interest. Interest on any Security 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 Security (or one or more predecessor Securities) is registered at the close of business on the regular record date for such payment at the office or agency of the Issuers maintained for such purpose pursuant to Section 2.3.

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

(a) The Issuers may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective predecessor Securities)

-57-

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 Issuers shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment (the “Special Interest Payment Date”), and at the same time the Issuers 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 Issuers 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 Issuers shall promptly notify the Trustee of such Special Record Date, and in the name and at the expense of the Issuers, the Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 11.2, 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 Securities (or their respective predecessor Securities) 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 Issuers may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuers 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 Security delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 2.15. Computation of Interest. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 2.16. CUSIP, Common Code and ISIN Numbers. The Issuers in issuing the Securities 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 Securities 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 Securities, 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 Issuers shall promptly notify the Trustee in writing of any change in the CUSIP, Common Code and ISIN numbers.

(5) 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

-61-

(6) 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 and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of ASC-815) will not be deemed to be an Incurrence of Indebtedness for purposes of this Section 3.2.

The Company will not permit any of its Unrestricted Subsidiaries to Incur any Indebtedness 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 Company shall be in Default of this Section 3.2).

This Indenture will 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. The Company 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 its Capital Stock (including any payment or distribution in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) except:

(a) dividends or distributions by the Company payable solely in Capital Stock of the Company (other than Disqualified Stock); and

(b) dividends or distributions payable to the Company or a Restricted Subsidiary and if such Restricted Subsidiary is not a Wholly-Owned Subsidiary, to minority stockholders (or owners of an equivalent interest in the case of a Subsidiary that is an entity other than a corporation) so long as the Company or a Restricted Subsidiary receives at least its pro rata share of such dividend or distribution;

(2) purchase, repurchase, redeem, defease or otherwise acquire or retire for value any Capital Stock of the Company or any direct or indirect parent of the Company held by Persons other than the Company or a Wholly-Owned Subsidiary;

(3) (a) 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

(4) make any Restricted Investment in any Person;

(any such dividend, distribution, purchase, repurchase, redemption, defeasance, other acquisition or retirement or Restricted Investment referred to in clauses (1) through (4) is referred to herein as a “Restricted Payment”), if at the time the Company or such Restricted Subsidiary makes such Restricted Payment:

(a) a Default has occurred and is continuing (or would result therefrom);

(b) the Company is not able to Incur an additional $1.00 of Indebtedness pursuant to Section 3.2(a) after giving effect, on a pro forma basis, to such Restricted Payment; or

(c) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made on or after October 13, 2010 (other than under clauses (1), (2), (4), (5), (6), (7), (8), (9), (10), and (11) of the next paragraph) would exceed the sum of the following:

(i) 50% of Consolidated Net Income accrued on a cumulative basis for the period (treated as one accounting period) from October 1, 2010 to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for which financial statements are in existence (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit);

(ii) 100% of the aggregate Net Cash Proceeds and the Fair Market Value of any Capital Stock of Persons engaged primarily in the Oil and Gas Business or assets used in the Oil and Gas Business, in each case received by the Company from the issue or sale of its Capital Stock (other than Disqualified Stock) or from cash capital contributions subsequent to October 13, 2010 (excluding (A) $300.0 million of such proceeds or capital contributions received by the Company in November 2016 and (B) Net Cash Proceeds received from an issuance or sale of such Capital Stock to (x) a Subsidiary of the Company or (y) an employee stock ownership plan, option plan or similar trust (to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination));

-63-

(iii) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to October 13, 2010 of any Indebtedness of the Company or its Restricted Subsidiaries convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company (less the amount of any cash, or the Fair Market Value of any other property (other than such Capital Stock), distributed by the Company upon such conversion or exchange), together with the net proceeds, if any, received by the Company or any of its Restricted Subsidiaries upon such conversion or exchange; and

(iv) the amount equal to the aggregate net reduction in Restricted Investments made by the Company or any of its Restricted Subsidiaries in any other Person after October 13, 2010 resulting from:

(A) repurchases, repayments or redemptions of such Restricted Investments by such Person, proceeds realized upon the sale of such Restricted Investments (other than to a Subsidiary of the Company), or repayments of loans or advances or other transfers of assets (including by way of dividend or distribution) by such Person to the Company or any Restricted Subsidiary; and

(B) the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of “Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary, which amount in each case under this clause (iv) was included in the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this clause (iv) to the extent it is already included in Consolidated Net Income.

The provisions of the preceding paragraph 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 Company (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of the Company or an employee stock ownership plan, option plan or similar trust to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or guaranteed by the Company 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 Company from the owners of its Capital Stock; provided that the Net Cash Proceeds from such sale of Capital Stock or capital contribution will be excluded from clause (c)(ii) of the preceding paragraph;

-64-

(2) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations of an Issuer or Guarantor Subordinated Obligations of any Subsidiary Guarantor made by exchange for, or out of the proceeds of the substantially concurrent sale of Refinancing Indebtedness with respect to such Subordinated Obligations or Guarantor Subordinated Obligations permitted to be Incurred pursuant to Section 3.2.

(3) 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 amounts available for Restricted Payments pursuant to clause (4)(c) above; and provided further, however, that for purposes of clarification, this clause (3) shall not include cash payments in lieu of the issuance of fractional shares included in clause (8) below;

(4) 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 Company held by any existing or former employees, officers or directors of the Company or the General Partner or any Restricted Subsidiary of the Company 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 employees, officers or directors, in each case approved by the Company’s Board of Directors; provided that such repurchases or other acquisitions pursuant to this clause (4) will not exceed $5.0 million in the aggregate during any calendar year; and provided that the proceeds received from any such transaction will be excluded from clause (c)(ii) of the preceding paragraph;

(5) purchases, repurchases, redemptions or other acquisitions or retirements for value of Capital Stock deemed to occur upon the exercise of stock options, warrants, rights to acquire Capital Stock or other convertible securities if such Capital Stock represents a portion of the exercise or exchange price thereof, and any purchases, repurchases, redemptions or other acquisitions or retirements for value of Capital Stock made in lieu of withholding taxes in connection with any exercise or exchange of warrants, options or rights to acquire Capital Stock;

(6) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of any Subordinated Obligation (i) at a purchase price not greater than 101% of the principal amount of such Subordinated Obligation in the event of a Change of Control in accordance with provisions similar to Section 3.9 or (ii) at a purchase price not greater than 100% of the principal amount thereof in accordance with provisions similar to Section 3.5; provided that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Company has made the Change of Control Offer or Asset Disposition Offer, as applicable, as provided in such Section with respect to the Securities and has completed the repurchase of all Securities accepted for payment in connection with such Change of Control Offer or Asset Disposition Offer;

-65-

(7) so long as no Default has occurred and is continuing, payments or distributions to dissenting equityholders pursuant to applicable law or in connection with the settlement or other satisfaction of legal claims made pursuant to or in connection with a consolidation, merger or transfer of assets;

(8) cash payments in lieu of the issuance of fractional shares;

(9) the declaration and payment of scheduled or accrued dividends to holders of any class of or series of Disqualified Stock of the Company issued after the Issue Date in accordance with Section 3.2, to the extent such dividends are included in Consolidated Interest Expense;

(10) so long as the Company is treated for U.S. federal tax purposes as a disregarded entity or partnership, Permitted Tax Distributions;

(11) dividends paid or distributions made by the Company, or purchases, repurchases, redemptions or other acquisitions or retirements for value of Capital Stock of the Company, within 60 days after October 13, 2010 from proceeds of the issuance of the Company’s 9 5/8% Senior Notes due 2018 in an aggregate amount not to exceed $50.0 million; and

(12) so long as no Default has occurred and is continuing, Restricted Payments in an amount not to exceed $25.0 million in the aggregate since the Issue Date.

The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of such Restricted Payment of the securities or other assets proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. The Fair Market Value of any cash Restricted Payment shall be its face amount, and the Fair Market Value of any non-cash Restricted Payment shall be determined in accordance with the definition of that term. Not later than the date of making any Restricted Payment pursuant to clause (c) of the second preceding paragraph or clause (12) of the preceding paragraph, the Company shall deliver to the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 3.3 were computed and the amounts available for Restricted Payments pursuant to clause (4)(c) above after giving effect to such Restricted Payment.

In the event that a Restricted Payment meets the criteria of more than one of the exceptions described in clauses (1) through (12) above or is entitled to be made pursuant to the first paragraph above, the Company shall, in its sole discretion, classify such Restricted Payment and may later re-classify all or a portion of such Restricted Payment.

The Company will 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 Company and its Restricted Subsidiaries (except to the extent 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, whether pursuant to the first paragraph of this Section 3.3 or under clause (12) of the second paragraph of this Section 3.3, or pursuant to the definition of “Permitted Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

-66-

SECTION 3.4. Limitation on Restrictions on Distributions from Restricted Subsidiaries. The Company will not, and will not permit any Restricted Subsidiary (other than the Co-Issuer) 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 to:

(1) pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Company or any other 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 Company or any other Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness Incurred by the Company 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 Company or any other Restricted Subsidiary.

The preceding provisions will not prohibit:

(i) any encumbrance or restriction pursuant to or by reason of an agreement in effect at or entered into on the Issue Date, including this Indenture and the Senior Secured Credit Agreement, each as in effect on such date;

(ii) any encumbrance or restriction with respect to a Person pursuant to or by reason of an agreement relating to any Capital Stock or Indebtedness Incurred by a Person on or before the date on which such Person was acquired by the Company or another Restricted Subsidiary (other than Capital Stock or Indebtedness Incurred as consideration in, or to provide all or any portion of the funds utilized to consummate, the transaction or series of related transactions pursuant to which such Person was acquired by the Company or a Restricted Subsidiary or in contemplation of the transaction) and outstanding on such date; provided that any such encumbrance or restriction shall not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property so acquired;

(iii) any encumbrance or restriction contained in contracts entered into in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of, or from the ability of the Company and the Restricted Subsidiaries to realize the value of, property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary;

-67-

(iv) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement effecting a refunding, replacement or refinancing of Indebtedness Incurred pursuant to an agreement referred to in clauses (i) and (ii) or clause (ix) of this paragraph or this clause (iv) or contained in any amendment, restatement, modification, renewal, supplemental, refunding, replacement or refinancing of an agreement referred to in clauses (i) and (ii) or clause (ix) of this paragraph or this clause (iv); provided that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement taken as a whole are no less favorable in any material respect to the holders of the Securities than the encumbrances and restrictions contained in the agreements governing the Indebtedness being refunded, replaced or refinanced;

(v) in the case of clause (3) of the first paragraph of this Section 3.4, any encumbrance or restriction:

(A) that restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties), license or similar contract, or the assignment or transfer of any such lease (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties), license (including licenses of intellectual property) or other contract;

(B) contained in mortgages, pledges or other security agreements permitted under this Indenture securing Indebtedness of the Company or a Restricted Subsidiary to the extent such encumbrances or restrictions restrict the transfer of the property subject to such mortgages, pledges or other security agreements;

(D) pursuant to customary provisions restricting dispositions of real property interests set forth in any reciprocal easement agreements of the Company or any Restricted Subsidiary;

-68-

(E) on cash or other deposits imposed by customers under contracts entered into in the ordinary course of business; or

(F) with respect to the disposition or distribution of assets or property in operating agreements, joint venture agreements, development agreements, area of mutual interest agreements and other agreements that are customary in the Oil and Gas Business and entered into in the ordinary course of business;

(vi) any encumbrance or restriction contained in (a) purchase money obligations for property acquired in the ordinary course of business and (b) Capitalized Lease Obligations, in each case that are permitted under this Indenture and that impose encumbrances or restrictions of the nature described in clause (3) of the first paragraph of this Section 3.4 on the property or assets so acquired, and any proceeds thereof;

(vii) any encumbrance or restriction with respect to a Restricted Subsidiary (or any of its property or assets) imposed pursuant to an agreement entered into for the direct or indirect sale or other disposition of all or a portion of the Capital Stock or property or assets of such Restricted Subsidiary pending the closing of such sale or other disposition;

(viii) any encumbrance or restriction arising or existing by reason of applicable law or any applicable rule, regulation or order;

(ix) any encumbrance or restriction contained in agreements governing Indebtedness of the Company or any of its Restricted Subsidiaries permitted to be Incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 3.2; provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness, taken as a whole, are not materially less favorable to the Company taken as a whole, as determined by the Board of Directors of the Company in good faith, than the provisions contained in the Senior Secured Credit Agreement and in this Indenture; and

(x) any encumbrance or restriction on cash or other deposits or net worth imposed by customers under contracts or required by insurance, surety or bonding companies, in each case entered into or incurred in the ordinary course of business.

-69-

SECTION 3.5. Limitation on Sales of Assets and Subsidiary Stock. The Company will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

(1) the Company or such Restricted Subsidiary, as the case may be, 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) at least 75% of the consideration received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; and

(3) except as provided in the next paragraph, an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied, within 360 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, by the Company or such Restricted Subsidiary, as the case may be:

(a) to prepay, repay, redeem or purchase Indebtedness (other than intercompany Indebtedness, Subordinated Obligations, Capital Stock or Indebtedness owed to an Affiliate of the Company); provided, however, that, in connection with any prepayment, repayment, redemption or purchase of Indebtedness pursuant to this clause (a), the Company or such Restricted Subsidiary will cause the related commitment to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or purchased; or

(b) to invest in Additional Assets or to make capital expenditures in the Oil and Gas Business;

provided that pending the final application of any such Net Available Cash in accordance with clause (a) or clause (b) above, the Company and its Restricted Subsidiaries may temporarily reduce revolving credit Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by this Indenture.

The requirement of clause 3(b) above shall be deemed to be satisfied if a bona fide binding contract committing to make the acquisition referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Company within the time period specified in the preceding clause (3) and such Net Available Cash is subsequently applied in accordance with such contract within 180 days following the date such agreement is entered into.

Any Net Available Cash from Asset Dispositions that is not applied or invested as provided in the preceding paragraph will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $20.0 million, within 10 Business Days thereof, the Company will make an offer (“Asset Disposition Offer”) to all Holders of Securities and, to the extent required by the terms of other Pari Passu Indebtedness, to all holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Company to make an offer to purchase such Pari Passu Indebtedness with the proceeds from any Asset Disposition (“Pari Passu Securities”) to purchase the maximum principal amount of Securities and any such Pari Passu Securities to which the Asset Disposition Offer applies that may be purchased out of the

-70-

Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or, in the event such Pari Passu Indebtedness was issued with original issue discount, 100% of the accreted value thereof) of the Securities and Pari Passu Securities plus accrued and unpaid interest, if any (or in respect of such Pari Passu Securities, such lesser price, if any, as may be provided for by its terms), to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the procedures set forth in this Section 3.5 or the agreements governing the Pari Passu Securities, as applicable, in each case in a minimum principal amount of $2,000 and integral multiples of $1,000 in excess thereof. If the aggregate principal amount of Securities surrendered by Holders thereof and other Pari Passu Securities surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Securities to be purchased on a pro rata basis (or, in the case of Securities issued in global form as discussed in Section 2.1(e) the Trustee will select the Securities for purchase based on DTC’s method that most nearly approximates a pro rata selection) on the basis of the aggregate principal amount of tendered Securities and Pari Passu Securities. To the extent that the aggregate amount of Securities and Pari Passu Securities so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company 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.

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 two Business Days after the termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the Company will purchase the principal amount of Securities and Pari Passu Securities 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 Securities and Pari Passu Securities validly tendered and not properly withdrawn in response to the Asset Disposition Offer.

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 will be paid to each 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 Securities pursuant to the Asset Disposition Offer.

On or before the Asset Disposition Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Securities and Pari Passu Securities or portions of Securities and Pari Passu Securities 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 Securities and Pari Passu Securities so validly tendered and not properly withdrawn, in each case in a minimum principal amount of $2,000 and integral multiples of $1,000 in excess thereof. The Company will deliver to the Trustee an Officers’ Certificate stating that such Securities or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.5 and, in addition, the Company will

-71-

deliver all certificates required, if any, by the agreements governing the Pari Passu Securities. On the Asset Disposition Date, the Company or the paying agent, as the case may be, will mail or deliver to each tendering Holder of Securities or holder or lender of Pari Passu Securities, as the case may be, an amount equal to the purchase price of the Securities or Pari Passu Securities so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Security, and the Trustee, upon delivery of an Officers’ Certificate from the Issuers, will authenticate and mail or deliver such new Security to such Holder, in a principal amount equal to any unpurchased portion of the Security surrendered; provided that each such new Security will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. In addition, the Company will take any and all other actions required by the agreements governing the Pari Passu Securities. Any Security not so accepted will be promptly mailed or delivered by the Issuers to the Holder thereof. The Company will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date.

The Company 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 Securities 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 Company 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.

For the purposes of clause (2) of the first paragraph of this Section 3.5, the following will be deemed to be cash:

(1) the assumption by the transferee of Indebtedness of the Company or Indebtedness of a Restricted Subsidiary (other than intercompany Indebtedness, Subordinated Obligations, Capital Stock or Indebtedness owed to an Affiliate of the Company) and the release of such Issuers or Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition;

(2) with respect to any Asset Disposition of oil and natural gas properties by the Company or any of its Restricted Subsidiaries where the Company or such Restricted Subsidiary retains an interest in such property, any agreement by the transferee (or an Affiliate thereof) to pay all or a portion of the costs and expenses of the Company or such Restricted Subsidiary related to the exploration, development, completion or production of such properties and activities related thereto;

(3) any Additional Assets;

(4) any Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Disposition having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (4), not to exceed an amount equal to 5.0% of the Company’s Adjusted Consolidated Net Tangible Assets (determined at the time of receipt of such Designated Non-cash Consideration), with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value; and

-72-

(5) securities, notes or other obligations received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or such Restricted Subsidiary into cash within 30 days after receipt thereof.

SECTION 3.6. Limitation on Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur 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, which Lien is securing any Indebtedness, unless contemporaneously with the Incurrence of such Lien effective provision is made to secure the Indebtedness due under the Securities (in the case of the Company) or any Subsidiary Guarantee of such other Restricted Subsidiary, equally and ratably with (or senior in priority to in the case of Liens with respect to Subordinated Obligations or Guarantor Subordinated Obligations, as the case may be) the Indebtedness secured by such Lien for so long as such Indebtedness is so secured.

SECTION 3.7. Statement by Officers as to Default. The Issuers shall, so long as any Security is outstanding, deliver to the Trustee within thirty days after the occurrence of a Default, an Officers’ Certificate setting forth the details of such Default, and what action the Issuers are taking or proposing to take with respect thereto.

SECTION 3.8. Limitation on Affiliate Transactions. The Company 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 Company (an “Affiliate Transaction”) unless:

(1) the terms of such Affiliate Transaction are no less favorable to the Company 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, or, if in the good faith judgment of the Board of Directors of the Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view ;

(2) if such Affiliate Transaction involves an aggregate consideration in excess of $20.0 million, the terms of such transaction have been approved by a majority of the members of the Board of Directors of the Company having no personal stake in such transaction, if any (and such majority determines that such Affiliate Transaction satisfies the criteria in clause (1) above); and

(3) if such Affiliate Transaction involves an aggregate consideration in excess of $50.0 million, the Board of Directors of the Company has received a written

-73-

opinion from an independent investment banking, accounting, engineering or appraisal firm of nationally recognized standing that such Affiliate Transaction is fair, from a financial standpoint, to the Company or such Restricted Subsidiary or, in the case of non-financial transactions, is not less favorable to the Company or such Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate.

The preceding paragraph will not apply to:

(1) any Restricted Payment permitted to be made pursuant to Section 3.3;

(2) any issuance of Capital Stock (other than Disqualified Stock), or other payments, awards or grants in cash, Capital Stock (other than Disqualified Stock) or otherwise pursuant to, or the funding of, any employment, consulting, service or severance agreements or other compensation arrangements, options to purchase Capital Stock (other than Disqualified Stock) of the Company, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar employee benefits plans or insurance and indemnification arrangements provided to or for the benefit of directors, officers and employees, in each case in the ordinary course of business and approved by the Board of Directors of the Company;

(3) any merger or other transaction with an Affiliate solely for the purpose of reincorporating or reorganizing the Company or any of its Restricted Subsidiaries in another jurisdiction or creating a holding company for the Company;

(4) advances to or reimbursements of employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the ordinary course of business of the Company or any of its Restricted Subsidiaries;

-74-

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

(11) in the case of contracts for exploring for, producing, marketing, storing or otherwise handling Hydrocarbons, or activities or services reasonably related or ancillary thereto, or other operational contracts, any such contracts entered into in the ordinary course of business and otherwise in compliance with the terms of this Indenture (a) which are fair to the Company and its Restricted Subsidiaries, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party, in either case in the reasonable determination of the Board of Directors of the Company or the senior management thereof, and (b) with respect to which the Company has complied with clauses (2) and (3) of the preceding paragraph to the extent applicable; and

(12) the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any agreement to which the Company or any of its Restricted Subsidiaries is a party as of or on the Issue Date that is disclosed in the Offering Memorandum under “Certain Relationships and Related Party Transactions,” as these agreements may be amended, modified, supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification, supplement, extension or renewal entered into after the Issue Date will be permitted only to the extent that its terms are not materially more disadvantageous, taken as a whole, to the holders of the Securities than the terms of the agreements in effect on the Issue Date.

SECTION 3.9. Purchase of Securities Upon a Change of Control. If a Change of Control occurs, unless the Issuers have previously or concurrently exercised their right to redeem all of the Securities pursuant to Article V, each Holder will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof ) of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount of the Securities plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

-75-

Within 30 days following any Change of Control, unless the Issuers have previously or concurrently exercised their right to redeem all of the Securities pursuant to Article V, the Company will provide notice (the “Change of Control Offer”) to each Holder, with a copy to the Trustee, stating:

(1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount of such Securities plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant interest payment date) (the “Change of Control Payment”);

(2) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is provided) (the “Change of Control Payment Date”);

(3) that any Security not properly tendered will remain outstanding and continue to accrue interest;

(4) that unless the Company defaults in the payment of the Change of Control Payment, all Securities accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date;

(5) that Holders electing to have any Securities purchased pursuant to a Change of Control Offer will be required to surrender such Securities, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Securities in certificated form completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their tendered Securities and their election to require the Company to purchase such Securities, provided that the Paying Agent receives, not later than the close of business on the third Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder of the Securities, the principal amount of Securities tendered for purchase, and a statement that such Holder is withdrawing its tendered Securities and its election to have such Securities purchased;

(7) that if the Company is repurchasing a portion of the Security of any Holder, the Holder will be issued a new Note equal in principal amount to the unpurchased portion of the Note surrendered, provided that the unpurchased portion of the Note must be equal to a minimum principal amount of $2,000 and an integral multiple of $1,000 in excess thereof; and

(8) the procedures determined by the Company, consistent with this Indenture, that a Holder must follow in order to have its Securities repurchased.

On the Change of Control Payment Date, the Company will, to the extent lawful:

(1) accept for payment all Securities or portions of Securities (in a minimum principal amount of $2,000 and integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer and not properly withdrawn;

-76-

(2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities accepted for payment; and

(3) deliver or cause to be delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions of Securities being purchased by the Company.

The Paying Agent will promptly mail or deliver to each Holder of Securities accepted for payment the Change of Control Payment for such Securities, and the Trustee, upon receipt of an Issuer Order, will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that each such new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, will be paid to each Person in whose name a Security is registered at the close of business on such record date, and no further interest will be payable to Holders who tender pursuant to the Change of Control Offer.

The Company is not required to make a Change of Control Offer upon a Change of Control if any other Person makes the Change of Control Offer in the manner, at the times and otherwise in compliance with this Section 3.9 applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not properly withdrawn under such Change of Control Offer.

A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer.

The Company 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 Securities as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 3.9, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.9 by virtue of its compliance with such securities laws or regulations.

SECTION 3.10. Provision of Financial Information. Whether or not the Company is subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, the Company will make available to the Trustee and the Holders of the Securities without cost, by posting the same on the Company’s website or the SEC’s XXXXX filing system as further provided below for public availability, the annual reports and the information, documents and other reports that are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation that would be due after the Issue Date, within the time periods specified therein with respect to a non-accelerated filer. The Company will file a copy of each of the reports referred to in the preceding sentence with the SEC for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the SEC will not accept such a filing).

-77-

This Section 3.10 will not impose any duty on the Company under the Xxxxxxxx-Xxxxx Act of 2002 and the related SEC rules that would not otherwise be applicable.

For the avoidance of doubt, (a) any such reports or other information delivered pursuant to the foregoing will not be required to contain the separate financial information for Subsidiary Guarantors as contemplated by Rule 3-10 of Regulation S-X or any financial statements of unconsolidated subsidiaries or 50% or less owned persons as contemplated by Rule 3-09 of Regulation S-X or any schedules required by Regulation S-X, or in each case any successor provisions and (b) such information shall not be required to comply with Regulation G under the Exchange Act or Item 10(e) of Regulation S-K with respect to any non-GAAP financial measures contained therein.

If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the financial information required will include, to the extent material, a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and 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 Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

The availability of the foregoing materials on the SEC’s website or on the Company’s website shall be deemed to satisfy the foregoing delivery obligations.

For so long as any Securities remain outstanding and constitute “restricted securities” under Rule 144, the Company will furnished to the holders of the Securities, and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

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 Issuers’ compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

SECTION 3.11. Future Subsidiary Guarantors. The Company will cause (a) each Domestic Subsidiary of the Company formed or acquired after the Issue Date and (b) any other Restricted Subsidiary (except the Co-Issuer) that is not already a Subsidiary Guarantor that guarantees any Indebtedness of the Company, or 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 Securities 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.

-78-

SECTION 3.12. Maintenance of Office or Agency. The Issuers will maintain an office or agency where the Securities may be presented or surrendered for payment, where, if applicable, the Securities may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Issuers in respect of the Securities and this Indenture may be served. The corporate trust office of the Trustee indicated in Section 2.3 shall be such office or agency of the Issuers, unless the Issuers shall designate and maintain some other office or agency for one or more of such purposes. The Issuers will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Issuers 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 11.2, and the Issuers hereby appoint the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

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

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

SECTION 3.14. Payment of Taxes. The Issuers or any Subsidiary Guarantor shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, all material taxes, assessments and governmental charges levied or imposed upon the Issuers or any Subsidiary Guarantor or upon the income, profits or property of the Issuers or any Subsidiary Guarantor; provided, however, (i) that the Issuers or any Subsidiary Guarantors 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 and (ii) that the Issuers and Subsidiary Guarantors are not required to pay or discharge taxes for which a failure to pay or discharge the same could not reasonably be expected to have a material adverse affect on the Company and the Restricted Subsidiaries taken as a whole.

SECTION 3.15. Payments for Consent. Neither the Company nor any of its Restricted Subsidiaries will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fees or otherwise, to any Holder of any Securities for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid or is paid to all Holders of the

-79-

Securities that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment. Notwithstanding the foregoing, with respect to any payment of consideration for, or as an inducement to, any consent, waiver or amendment of any of the terms or provisions of the Indenture, the Notes or the Subsidiary Guarantees in connection with a tender offer or exchange offer for the Notes, the Company and any of its Restricted Subsidiaries may exclude (i) holders or Beneficial Owners of the Notes that are not “qualified institutional buyers” as defined in Rule 144A under the Securities Act, or “non-U.S. Persons” as defined in Regulation S under the Securities Act, and (ii) holders or Beneficial Owners of the Notes in any jurisdiction (other than the United States) where the inclusion of such holders or Beneficial Owners would require the Company or any such Restricted Subsidiary to comply with the registration requirements or other similar requirements under any securities laws of such jurisdiction, or the solicitation of such consent, waiver or amendment from, or the granting of such consent or waiver, or the approval of such amendment by, holders or Beneficial Owners in such jurisdiction would be unlawful, in each case as determined by the Company in its sole discretion.

SECTION 3.16. Compliance Certificate. The Issuers and the Subsidiary Guarantors shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company ending after the Issue Date a statement (which need not be an Officers’ Certificate) signed by two Officers of the Company, one of which shall be the principal executive officer, the principal accounting officer or the principal financial officer of the Company, stating that a review of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each of the Issuers and the Subsidiary Guarantors has performed its 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 Issuers are taking or proposes to take with respect thereto. The Issuers also shall comply with TIA § 314(a)(4).

SECTION 3.17. Business Activities. The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole. The Co-Issuer may not engage in any business not related directly or indirectly to obtaining money or arranging financing for the Company or its Restricted Subsidiaries, the Co-Issuer may not have any Subsidiary, and no Person other than the Company or any of its other Restricted Subsidiaries may own any Capital Stock of the Co-Issuer.

ARTICLE IV

SUCCESSOR COMPANY

SECTION 4.1. Merger and Consolidation.

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

(1) the resulting, surviving or transferee Person (the “Successor Company”) will be a corporation (in the case of either the Company or the Co-Issuer) or a partnership, trust or limited liability company (but only in the case of the 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 the Successor Company (if not the Company or the Co-Issuer, as the case may be) will expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company or the Co-Issuer, as the case may be, under this Indenture, the Securities and the Registration Rights Agreement;

(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;

(3) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, conveyance, lease or other disposition has been made, would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period (a) be permitted to incur at least $1.00 of additional Indebtedness pursuant to Section 3.2(a), or (b) have had a Consolidated Coverage Ratio equal to or greater than the actual Consolidated Coverage Ratio for the Company for such four-quarter period;

(4) if an Issuer is not the Successor Company in any of the transactions referred to above that involve such Issuer, each Subsidiary 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 Subsidiary Guarantee shall apply to the Successor Company’s obligations in respect of this Indenture and the Securities and that its Subsidiary Guarantee shall continue to be in effect; and

(5) the Company or the Co-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.

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

Upon satisfaction of the foregoing requirements, as applicable, the Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company or the Co-Issuer, as the case may be, under this Indenture; 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.

-81-

Notwithstanding the preceding clause (3), (x) any Restricted Subsidiary (other than the Co-Issuer) may consolidate with, merge into or transfer all or part of its assets to the Company and the Company may consolidate with, merge into or transfer all or part of its assets to a Subsidiary Guarantor and (y) the Company may merge with an Affiliate formed solely for the purpose of reorganizing the Company in another jurisdiction.

(b) In addition, the Company will not permit any Subsidiary Guarantor to consolidate with or merge with or into, and will not permit the conveyance, transfer or lease of all or substantially all of the assets of any Subsidiary Guarantor to, any Person (other than the Company or another Subsidiary Guarantor) unless:

(1) either (A) (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, in form reasonably satisfactory to the Trustee, all the obligations of the Subsidiary Guarantor under this Indenture, Subsidiary Guarantee and the applicable Registration Rights Agreement 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

(B) the transaction results in the release of the Subsidiary Guarantor from its obligations under its Subsidiary Guarantee in compliance with Section 10.2; and

(2) the Company 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.

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

SECTION 5.3. Election to Redeem; Notice to Trustee. In case of any redemption at the election of the Issuers, the Issuers 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

-82-

Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed and, in the case of any redemption of less than all Securities, shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 5.4. Any such notice may be cancelled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect.

SECTION 5.4. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities are to be redeemed at any time pursuant to an optional redemption, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the outstanding Securities not previously called for redemption, in compliance with the requirements, as set forth in an Officers’ Certificate delivered by the Issuers to the Trustee, of the principal national securities exchange, if any, on which such Securities are listed, or, if such Securities are not so listed, then on a pro rata basis (or, in the case of Securities issued in global form as discussed in Section 2.1(e) the Trustee will select the Securities for purchase based on DTC’s method that most nearly approximates a pro rata selection), by lot or by such other method as the Trustee in its sole discretion will deem to be fair and appropriate (and in such manner as complies with applicable legal requirements), and which may provide for the selection for redemption of portions of the Securities in the principal amount of $2,000 and integral multiples of $1,000 in excess thereof; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than $2,000.

The Trustee shall promptly notify the Issuers in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the method it has chosen for the selection of Securities 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 Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

SECTION 5.5. Notice of Redemption. Notice of redemption shall be given in the manner provided for in Section 11.2 not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed. At the Issuers’ request, the Trustee shall give notice of redemption in the Issuers’ name and at the Issuers’ 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 Issuers’ expense and setting forth the information to be stated in such notice as provided in the following items.

All notices of redemption shall state:

(1) the Redemption Date,

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

-83-

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

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

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

(6) the place or places where such Securities 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 Securities 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 Securities, and

(10) the paragraph of the Securities pursuant to which the Securities are to be redeemed.

SECTION 5.6. Deposit of Redemption Price. Prior to 11:00 a.m., New York City time, on any Redemption Date, the Issuers shall deposit with the Trustee or with a Paying Agent an amount of money sufficient to pay the redemption price of and accrued interest (including Additional Interest) on, all the Securities which are to be redeemed on that date, other than Securities or portions of Securities called for redemption that are beneficially owned by the Issuers and have been delivered by the Issuers to the Trustee for cancellation.

SECTION 5.7. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities or portions of Securities so to be redeemed 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 Issuers shall default in the payment of the redemption price and accrued interest) such Securities 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 Securities to the

-84-

Redemption Date. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Issuers at the redemption price, together with accrued interest, if any, to the Redemption Date, provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holder of such Security, or one or more predecessor Securities, registered as such as of the relevant record date.

If any Security 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 Securities.

SECTION 5.8. Securities Redeemed in Part. Any Security which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at the office or agency of the Issuers maintained for such purpose pursuant to Section 3.12 (with, if the Issuers or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuers and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Issuers shall execute, and the Trustee shall, upon receipt of an Issuer Order, authenticate and make available for delivery to the Holder of such Security at the expense of the Issuers, a new Security or Securities, 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 Security so surrendered; provided, that each such new Security will be in a principal amount of $2,000 and integral multiples of $1,000 in excess thereof.

ARTICLE VI

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

-86-

(8) the commencement by the Company, the Co-Issuer or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the last audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary of a voluntary case or proceeding under any applicable Federal or State or foreign bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it or them to the entry of a decree or order for relief in an involuntary case or proceeding under any applicable Federal or State or foreign bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it or them, or the filing by it or them of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State or foreign law, or the consent by it or them to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company, the Co-Issuer or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the last audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary or of any substantial part of its or their property, or the making by it or them of an assignment for the benefit of creditors, or the failure by them or it to pay its or their debts generally as they become due; or

(9) failure by the Company, the Co-Issuer or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $20.0 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 Subsidiary Guarantee of a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary, 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 Company 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 Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary, denies or disaffirms its obligations under this Indenture or its Subsidiary Guarantee.

However, a default under clauses (4) and (5) of this Section 6.1 will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Issuers in writing and, in the case of a notice given by the Holders, the Trustee of the default and the Company or the Co-Issuer do not cure such default within the time specified in clauses (4) and (5) of this Section 6.1 after receipt of such notice.

-87-

SECTION 6.2. Acceleration. If an Event of Default (other than an Event of Default described in Section 6.1(7) and (8)) occurs and is continuing, the Trustee by notice to the Company and the Issuers, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Co-Issuer and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, accrued and unpaid interest, if any, on all the Securities to be due and payable. If an Event of Default described in Section 6.1(7) and (8) occurs and is continuing, the principal of, premium, if any, accrued and unpaid interest, if any, on all the Securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Notwithstanding the foregoing, if an Event of Default specified in Section 6.1(6) shall have occurred and be continuing, such Event of Default and any consequential acceleration (to the extent not in violation of any applicable law or in conflict with any judgment or decree of a court of competent jurisdiction) shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default has been repaid or (ii) if the default relating to such Indebtedness is waived by the holders of such Indebtedness or cured and if such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness, in each case within 20 days after the declaration of acceleration with respect thereto, and (iii) any other existing Events of Default, except nonpayment of principal, premium or interest on the Securities that became due solely because of the acceleration of the Securities, have been cured or waived.

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

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

SECTION 6.4. Waiver of Past Defaults. The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee (with a copy to the Issuers, 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, Securities), 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 (including Additional Interest) on a Security 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 Securityholder affected and (b) rescind any acceleration with respect to the Securities 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 (including Additional Interest) on the Securities 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.

-88-

SECTION 6.5. Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, the Securities or the Subsidiary Guarantees or, subject to Sections 7.1 and 7.2, that the Trustee determines is unduly prejudicial to the rights of other Securityholders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such direction is unduly prejudicial to such Securityholders) 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 against all losses and expenses caused by taking or not taking such action.

SECTION 6.6. Limitation on Suits. Subject to Section 6.7, a Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

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

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

(3) such Holders have offered the Trustee security or indemnity 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 Securities 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.

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

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

-89-

SECTION 6.8. Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.1 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuers 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 Securityholders allowed in any judicial proceedings relative to the Company, the Co-Issuer or the other 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 reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7.

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities 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 pay out the money in the following order:

FIRST: to 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 costs and expenses of collection;

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

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

The Trustee may fix a record date and payment date for any payment to Holders of Securities 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

-90-

undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by the Issuers, 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 Securities.

ARTICLE VII

TRUSTEE

SECTION 7.1. Duties of Trustee.

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.

(a) 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 Securities or the Subsidiary Guarantees, as applicable. However, in the case of any such certificates or opinions which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture, the Securities or the Subsidiary Guarantees, as the case may be (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

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

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

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

(3) the Trustee shall 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

-91-

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

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

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

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

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

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

SECTION 7.2. Rights of Trustee. Subject to Section 7.1:

(a) The Trustee may conclusively rely on any document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. The Trustee shall receive and retain financial reports and statements of the Issuers 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 Issuers.

(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.

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

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

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of counsel with respect to legal matters relating to this Indenture, the Securities or the Subsidiary Guarantees shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder or under the Securities or the Subsidiary Guarantees in good faith and in accordance with the advice or opinion of such counsel.

-92-

(f) The Trustee shall not be deemed to have knowledge or 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 11.2, and such notice references the Securities 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, 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 Securities or the Subsidiary Guarantees at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it in its sole discretion against the costs, expenses and liabilities which may be incurred therein or thereby.

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

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

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

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

(m) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

SECTION 7.3. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the

-93-

Issuers, the Subsidiary 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 Issuers; 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 Subsidiary Guarantees or the Securities, shall not be accountable for the Issuers’ use of the proceeds from the sale of the Securities, 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 Issuers pursuant to the terms of this Indenture and shall not be responsible for any statement of the Issuers in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

SECTION 7.5. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer has knowledge thereof, the Trustee shall provide notice to each Securityholder 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 Security (including payments pursuant to the optional redemption or required repurchase provisions of such Security), the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Securityholders.

SECTION 7.6. Reports by Trustee to Holders. Within 60 days after each December 15 beginning December 15, 2017, the Trustee shall mail to each Securityholder a brief report dated as of such December 15 that complies with TIA § 313(a) if and to the extent required thereby. The Trustee also shall comply with TIA § 313(b) and TIA § 313(c).

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof and the Trustee shall comply with TIA § 313(d).

SECTION 7.7. Compensation and Indemnity. The Issuers shall pay to the Trustee from time to time compensation for its services hereunder and under the Securities and the Subsidiary Guarantees as the Issuers 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 Issuers 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 mailing of notices to Securityholders. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuers shall indemnify the Trustee against any and all loss, liability, damages, claims or expense (including reasonable attorneys’ fees and expenses (including, without limitation, reasonable fees

-94-

and disbursements of counsel incurred by the Trustee in any action or proceeding between the Trustee and the Issuers or between the Trustee and any third party or otherwise)) incurred by it without willful misconduct, gross negligence or bad faith on its part in connection with the administration of this trust and the performance of its duties hereunder and under the Securities and the Subsidiary Guarantees, including the costs and expenses of enforcing this Indenture (including this Section 7.7), the Securities and the Subsidiary Guarantees and of defending itself against any claims (whether asserted by any Securityholder, the Issuers or otherwise). The Trustee shall notify the Issuers 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 Issuers shall not relieve the Issuers of its obligations hereunder except to the extent the Issuers are prejudiced thereby. The Issuers shall defend the claim and the Trustee shall provide reasonable cooperation at the Issuers’ expense in the defense. The Trustee may have separate counsel and the Issuers shall pay the fees and expenses of such counsel; provided that the Issuers 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, (i) there is no conflict of interest between the Issuers and the Trustee in connection with such defense or (ii) there are no legal defenses available to the Trustee that are different from or are in addition to those available to the Issuers.

To secure the Issuers’ payment obligations in this Section 7.7, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of, premium, if any, and interest on particular Securities. Such lien shall survive the satisfaction and discharge of this Indenture. 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 Issuers.

The Issuers’ payment obligations pursuant to this Section shall survive the discharge of this Indenture. 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.

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

-95-

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

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of at least 10% in principal amount of the Securities may petition, at the Issuers’ 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 Securityholder, who has been a bona fide holder of a Security 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 Issuers’ 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 Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Securities 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 Issuers are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

-96-

SECTION 7.11. Preferential Collection of Claims Against the Issuers. 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 Issuers. Any application by the Trustee for written instructions from the Issuers 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 Issuers 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 Securities; Defeasance.

(a) Subject to Section 8.1(c), when (i)(x) all Securities that have been authenticated (other than Securities replaced or paid pursuant to Section 2.10 and Securities for whose payment money has been deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from such trust), have been delivered to the Trustee for cancellation or (y) all outstanding Securities 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 will 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 Issuers, and the Issuers or any Subsidiary Guarantor has irrevocably deposited or caused to be deposited with the Trustee, as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, in such amount as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Securities not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of final maturity or redemption; (ii) the Issuers have paid or caused to be paid all sums payable by it under this Indenture; and (iii) the Issuers have delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of such Securities 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 Issuers (accompanied by an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with) and at the cost and expense of the Issuers. 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).

-97-

(b) Subject to Sections 8.1(c) and 8.2, the Issuers at any time may terminate (i) all of their obligations under the Securities and this Indenture (“legal defeasance option”), 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, 3.15 and 3.18 and Section 4.1 (other than Sections 4.1(a)(1), (2), (4) and (5)), and the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply with such covenants shall no longer constitute a Default or an Event of Default under Section 6.1(3) (as it relates to Section 4.1(a)(3)), Section 6.1(4) (to the extent applicable to such other defeased covenants), Section 6.1(6), Section 6.1(7) (with respect to Significant Subsidiaries), Section 6.1(8) (with respect to Significant Subsidiaries) and Section 6.1(9), and the events specified in such Sections shall no longer constitute an Event of Default (clause (ii) being referred to as the “covenant defeasance option”), but except as specified above, the remainder of this Indenture and the Securities shall be unaffected thereby. The Issuers may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Issuers exercise their legal defeasance or its covenant defeasance option, the Subsidiary Guarantees in effect at such time shall terminate.

If the Issuers exercise their legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default. If the Issuers exercise its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Section 6.1(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, 3.15 and 3.18), Section 6.1(5), Section 6.1(6), Section 6.1(7) (with respect only to Significant Subsidiaries), Section 6.1(8) (with respect only to Significant Subsidiaries), Section 6.1(9) or Section 6.1(10) or because of the failure of the Company or the Issuers to comply with Section 4.1(a)(3).

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

(c) Notwithstanding the provisions of Sections 8.1(a) and (b) to the extent relating to a legal defeasance, the Issuers’ obligations in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.10, 2.11, 2.12, 2.13, 3.12, 7.7 and 7.8 and in this Article VIII shall survive until the Securities have been paid in full. Thereafter, the Issuers’ obligations in Sections 7.7, 8.4 and 8.5 shall survive.

SECTION 8.2. Conditions to Defeasance. The Issuers may exercise its legal defeasance option or its covenant defeasance option only if:

(1) the Issuers or a Subsidiary Guarantor irrevocably deposits in trust with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, U.S. Government Obligations, or a combination of cash in U.S. dollars and U.S. Government

-98-

Obligations, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, and premium, if any, and interest, including Additional Interest, if any, due on the outstanding Securities on the Stated Maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the Securities are being defeased to Stated Maturity or to a particular redemption date;

(2) in the case of legal defeasance, the Issuers have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that since the Issue Date, (a) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling or (b) there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the respective outstanding Securities 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 Issuers have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) reasonably acceptable to the Trustee confirming that the Holders of the respective outstanding Securities 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) 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) to which the Issuers or any of the Restricted Subsidiaries is a party or by which the Issuers or any Restricted Subsidiaries are bound;

(5) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or insofar as Events of Default resulting from the borrowing of funds or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(6) the Issuers must deliver to the Trustee an Opinion of Counsel to the effect that, assuming, among other things, no intervening bankruptcy of the Issuers between the date of deposit and the 91st day following the deposit and assuming that no Holder is an “insider” of the Issuers under applicable bankruptcy law, after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization of similar laws affecting creditors’ rights generally;

-99-

(7) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of defeating, hindering, delaying or defrauding creditors of the Issuers or others; and

(8) the Issuers 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.

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 Securities to the Holders of the Securities of all sums due in respect of the payment of principal of, premium, if any, and accrued interest on the Securities.

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

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Issuers upon request any money held by them for the payment of principal of or premium, if any, or interest on the Securities that remains unclaimed by the Holders thereof for two years, and, thereafter, Securityholders entitled to the money must look to the Issuers 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 Issuers 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 Issuers and each Subsidiary Guarantor under this Indenture, the Securities and the Subsidiary Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article VIII; provided, however, that, if the Issuers or the Subsidiary Guarantors have made any payment of principal, premium, if any, or interest (including Additional Interest) on any Securities because of the reinstatement of their obligations, the Issuers or Subsidiary Guarantors, as the case may be, shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

-100-

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

ARTICLE IX

(2) to provide for the assumption by a successor corporation, partnership, trust or limited liability company of the obligations of the Company, the Co-Issuer or any Subsidiary Guarantor under this Indenture and the Securities;

(3) to provide for or facilitate the issuance of uncertificated Securities in addition to or in place of certificated Securities; provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code;

(4) to add Subsidiary Guarantors (or any other guarantors) with respect to the Securities, including Subsidiary Guarantors, or release a Subsidiary Guarantor from its Subsidiary Guarantee and terminate such Subsidiary Guarantee; provided that the release and termination is in accordance with the applicable provisions of this Indenture;

(5) to secure the Securities or the Subsidiary Guarantees;

(6) to add covenants of the Company, the Co-Issuer or a Subsidiary Guarantor for the benefit of the Holders or to surrender any right or power herein conferred upon the Company, the Co-Issuer or a Subsidiary Guarantor;

(8) to comply with any requirement of the SEC in connection with any required qualification of this Indenture under the TIA; or

(9) to evidence and provide for the acceptance of an appointment under this Indenture of a successor Trustee; provided that the successor Trustee is otherwise qualified and eligible to act as such under the terms of this Indenture.

-101-

SECTION 9.2. With Consent of Holders. The Issuers, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture, the Securities and the Subsidiary Guarantees without notice to any Securityholder but with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). Subject to Section 6.4 and 6.7, any past default or compliance with the provisions of this Indenture, the Securities or the Subsidiary Guarantees may be waived with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). However, without the consent of each Securityholder affected, an amendment, supplement or waiver may not:

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

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

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

(4) reduce the premium payable upon the redemption of any Security as described in Section 3.9, Article V hereof or paragraph 5 of any Security, change the time at which any Security may be redeemed as described in Section 3.9, Article V hereof or paragraph 5 of any Security or make any change relative to the Issuers’ obligation to make an offer to repurchase the Securities as a result of a Change of Control as described in Section 3.9 after (but not before) the occurrence of such Change of Control;

(5) make any Security payable in money other than U.S. dollars;

(6) impair the right of any Holder to receive payment of principal of, premium, if any, and interest (including Additional Interest) on such Holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;

(7) make any change to this Section 9.2;

(8) release any Subsidiary Guarantor from any of its obligations under its Subsidiary Guarantee otherwise than in accordance with the applicable provisions of this Indenture; or

(9) subordinate the Securities or any Subsidiary Guarantee in right of payment to any other Indebtedness of either Issuer or any Subsidiary Guarantor.

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 Securities given in connection with a tender or exchange of such Holder’s Securities will not be rendered invalid by such tender or exchange.

-102-

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

SECTION 9.3. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture, the Securities or the Subsidiary Guarantees shall comply with the TIA as then in effect.

SECTION 9.4. Revocation and Effect of Consents and Waivers. A consent to an amendment, supplement or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. Any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment, 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 Securityholder unless it makes a change described in any of clauses (1) through (9) of Section 9.2, and in that case the amendment, supplement, waiver or other action shall bind each Securityholder who has consented to it and every subsequent Securityholder that evidences the same debt as the consenting Holder’s Securities. An amendment, supplement or waiver under Section 9.2 shall become effective upon receipt by the Trustee of the requisite number of consents, and in relation to any Securities evidenced by Global Securities, 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 Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall become valid or effective more than 120 days after such record date.

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

-103-

SECTION 9.6. Trustee to Sign Amendments. The Trustee 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. If it does, the Trustee may but need not sign it. In signing any amendment, supplement or waiver the Trustee 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 Issuers and any Subsidiary Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.3).

ARTICLE X

GUARANTEE

SECTION 10.1. Guarantee. Subject to the provisions of this Article X, each Subsidiary Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Subsidiary Guarantor, to each Holder of the Securities, to the extent lawful, and the Trustee the full and punctual payment when due, whether at final maturity, by acceleration, by redemption or otherwise, of the Obligations. Each Subsidiary Guarantor agrees that the Obligations will rank equally in right of payment with other Indebtedness of such Subsidiary Guarantor, except to the extent such other Indebtedness is subordinate to the Obligations. Each Subsidiary 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 Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Issuers of any of the Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Obligations.

Each Subsidiary Guarantor further agrees that its Subsidiary 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 Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary 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 Issuers or any other person under this Indenture, the Securities 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

-104-

Indenture, the Securities 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 Subsidiary Guarantor; (f) any change in the ownership of the Issuers; (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 Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor agrees that its Subsidiary Guarantee herein shall remain in full force and effect until payment in full of all the Obligations or such Subsidiary Guarantor is released from its Subsidiary Guarantee upon the merger or the sale of all the Capital Stock or assets of the Subsidiary Guarantor or otherwise in compliance with Section 4.1, Section 10.2 or Article VIII, as applicable. Each Subsidiary Guarantor further agrees that its Subsidiary 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 Issuers 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 Subsidiary Guarantor by virtue hereof, upon the failure of the Issuers 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 Subsidiary Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee or the Trustee on behalf of the Holders an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest (including Additional Interest) on such Obligations then due and owing (but only to the extent not prohibited by law).

Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Subsidiary Guarantee 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 Subsidiary Guarantor for the purposes of this Subsidiary Guarantee.

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

The delivery of any Security by the Trustee, after authentication thereof hereunder, shall constitute delivery of the Subsidiary Guarantees set forth in this Indenture or any supplemental indenture on behalf of a Subsidiary Guarantor. Neither any Issuer nor any Subsidiary Guarantor shall be required to make a notation on any Security to reflect the Subsidiary Guarantees. The validity and enforceability of any Subsidiary Guarantee shall not be affected by the fact that a notation thereof is not affixed to any particular Security.

-105-

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 Agreement) 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 Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

(b) Upon the sale or disposition of a Subsidiary Guarantor (by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its assets (other than by lease)) and whether or not the Subsidiary Guarantor is the surviving entity in such transaction, to a Person which is not the Company or a Restricted Subsidiary of the Company, such Subsidiary Guarantor will be automatically released from all its obligations under this Indenture and its Subsidiary Guarantee if the sale or other disposition does not violate Section 3.5.

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

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

(e) Upon the liquidation or dissolution of such Subsidiary Guarantor, provided that no Default or Event of Default has occurred and is continuing.

(f) With respect to a Subsidiary Guarantor that is an Immaterial Subsidiary, such Subsidiary Guarantor will be released from its obligations under this Indenture and its Subsidiary Guarantee upon the liquidation or dissolution of such Subsidiary Guarantor.

(g) The release of any Subsidiary Guarantor from its obligations pursuant to this Section 10.2 shall be conditioned upon such Subsidiary Guarantor delivering to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent provided for in this Indenture relating to such release have been complied with.

SECTION 10.3. Right of Contribution. Each Subsidiary Guarantor hereby agrees that to the extent that any Subsidiary Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the Subsidiary Guarantees, such Subsidiary Guarantor

-106-

shall be entitled to seek and receive contribution from and against the Issuers or any other Subsidiary 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 Subsidiary Guarantor to the Trustee and the Holders and each Subsidiary Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Subsidiary Guarantor hereunder.

SECTION 10.4. No Subrogation. Notwithstanding any payment or payments made by each Subsidiary Guarantor hereunder, no Subsidiary Guarantor shall be entitled to be subrogated to any of the rights of the Trustee or any Holder against the Issuers or any other Subsidiary Guarantor or guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations, nor shall any Subsidiary Guarantor seek or be entitled to seek any contribution or reimbursement from the Issuers or any other Subsidiary Guarantor in respect of payments made by such Subsidiary Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Issuers on account of the Obligations are paid in full. If any amount shall be paid to any Subsidiary 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 Subsidiary Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Subsidiary Guarantor, and shall, forthwith upon receipt by such Subsidiary Guarantor, be turned over to the Trustee in the exact form received by such Subsidiary Guarantor (duly indorsed by such Subsidiary Guarantor to the Trustee, if required), to be applied against the Obligations.

[FORM OF REVERSE SIDE OF NOTE]

XXXX XXXX HOLDINGS, LP, AND XXXX XXXX FINANCE SERVICES CORP.

7.875% Senior Notes due 2024

Interest

Xxxx Xxxx Holdings, LP, a Texas limited partnership (the “Company”), and Xxxx Xxxx Finance Services Corp., a Delaware corporation (“Co-Issuer” together with the Company, the “Issuers”), jointly and severally promise to pay interest on the principal amount of this Security at the rate per annum shown above.

The Issuers will pay interest semiannually on June 15 and December 15 of each year commencing June 15, 2017. Interest on the Securities will accrue from the most recent date to which interest has been paid on the Securities or, if no interest has been paid, from the date of original issuance of the Notes. The Issuers shall pay interest on overdue principal at the above rate plus 1.0% to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

If an interest payment date falls on a day that is not a Business Day, the interest payment to be made on such interest payment date will be made on the next succeeding Business Day with the same force and effect as if made on such interest payment date, and no additional interest will accrue as a result of such delayed payment

[The Holder of this Note is entitled to the benefits of the Registration Rights Agreement. Additional Interest, if any, due under the Registration Rights Agreement, shall be paid to the same Persons, in the same manner and at the same times as regular interest.]¹

2.	Method of Payment

By no later than 11:00 a.m. (New York City time) on the date on which any principal of, premium, if any, or interest on any Security is due and payable, the Issuers shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal, premium, if any, and/or interest (including Additional Interest). The Issuers will pay interest (except Defaulted Interest) to the Persons who are registered Holders of Securities at the close of business on the June 1 or December 1 immediately preceding the interest payment date even if Securities are cancelled, repurchased or redeemed after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Issuers will pay principal, premium, if any, and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Securities represented by a Global Security (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 Issuers will make all payments in respect of a Definitive Security (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided,

¹	Include in Restricted Securities only.

A-3

however, that payments on the Securities may also be made, at the Issuers’ option, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if the Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3.	Paying Agent and Registrar

Initially, U.S. Bank National Association (the “Trustee”) will act as Trustee, Paying Agent and Registrar. The Issuers may appoint and change any Paying Agent, Registrar or co-registrar without notice to any Securityholder. The Company or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

Indenture

The Issuers issued the Securities under an Indenture dated as of December 8, 2016 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Issuers, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all terms and provisions of the Indenture, and Securityholders are referred to the Indenture and the Act for a statement of those terms.

The Securities are senior obligations of the Issuers. The aggregate principal amount of Securities that may be authenticated and delivered under the Indenture is unlimited. This Security is one of the 7.875% Senior Notes due 2024 referred to in the Indenture. The Securities include (i) $500,000,000 aggregate principal amount of the Issuers’ 7.875% Senior Notes due 2024 issued under the Indenture on December 8, 2016 (herein called “Initial Securities”), (ii) if and when issued, additional 7.875% Senior Notes due 2024 of the Issuers that may be issued from time to time under the Indenture subsequent to December 8, 2016 (herein called “Additional Securities”) as provided in Section 2.1(a) of the Indenture and (iii) if and when issued, the Issuers’ 7.875% Senior Notes due 2024 that may be issued from time to time under the Indenture in exchange for Initial Securities or Additional Securities in an offer registered under the Securities Act as provided in a Registration Rights Agreement (herein called “Exchange Securities”). The Initial Securities, Additional Securities and Exchange Securities are treated as a single class of securities under the Indenture. 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 making of payments for consents, the entering into of agreements that restrict distribution from 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 Securities by certain subsidiaries.

To guarantee the due and punctual payment of the principal, premium, if any, and interest (including post-filing or post-petition interest) on the Securities and all other amounts

A-4

payable by the Issuers under the Indenture, the Securities and the Registration Rights Agreement when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Subsidiary Guarantors have unconditionally guaranteed (and future guarantors, together with the Subsidiary Guarantors, will unconditionally guarantee), jointly and severally, such obligations on a senior basis pursuant to the terms of the Indenture.

5.	Redemption

Except as set forth below, the Securities will not be redeemable at the option of the Issuers prior to December 15, 2019. On and after such date, the Securities will be redeemable, at the Issuers’ option, in whole or in part, at any time upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each Holder’s registered address, at the following redemption prices (expressed in percentages of principal amount), plus accrued and unpaid interest (including Additional Interest) to 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 15 of the years set forth below:


Period	Redemption Price
2019		105.906	%
2020		103.938	%
2021		101.969	%
2022 and thereafter		100.000	%

In addition, at any time and from time to time prior to December 15, 2019, the Issuers may redeem in the aggregate up to 35% of the original principal amount of the Securities (calculated after giving effect to any issuance of Additional Securities) with the Net Cash Proceeds of one or more Equity Offerings at a redemption price (expressed as a percentage of principal amount) of 107.875% of the principal amount thereof, plus accrued and unpaid interest (including Additional Interest), if any, to 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 Securities (calculated after giving effect to any issuance of Additional Securities) must remain outstanding after each such redemption; and

(2) each such redemption occurs within 120 days of the date of closing of such Equity Offering.

In addition, at any time prior to December 15, 2019, upon not less than 30 nor more than 60 days’ prior notice given to each Holder as provided in the Indenture, the Issuers may redeem the Securities, in whole or in part, at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium plus accrued and unpaid interest (including Additional Interest), if any, to 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).

A-5

“Applicable Premium” means, with respect to a Security at any Redemption Date, the greater of (i) 1.0% of the principal amount of such Security or (ii) the excess, if any, of (A) the present value at such Redemption Date of (1) the redemption price of such Security on December 15, 2019 (such redemption price set forth in the table above) plus (2) all required interest payments (excluding accrued and unpaid interest to such Redemption Date) due on such Security through December 15, 2019, computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points, over (B) the principal amount of such Security.

“Treasury Rate” means, as of 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 15, 2019; provided, however, that if the period from the Redemption Date to December 15, 2019 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the Redemption Date to December 15, 2019 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

The Issuers will (a) calculate the Treasury Rate as of 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.

6.	Repurchase Provisions

If a Change of Control occurs, unless the Issuers have exercised its right to redeem all of the Securities as described under paragraph 5 of the Securities, each Holder will have the right to require the Issuers to repurchase from each Holder all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

7.	Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of principal amount of $2,000 and whole multiples of $1,000 in excess thereof. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay a sum sufficient to cover any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Security (A) for a period (1) of 15 days before a selection of Securities 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 Security being redeemed in part.

A-6

8.	Persons Deemed Owners

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

9.	Unclaimed Money

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

10.	Defeasance

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

11.	Amendment, Supplement, Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture, the Securities or the Subsidiary Guarantees may be amended or supplemented by the Issuers, the Subsidiary Guarantors and the Trustee with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities and (ii) any default (other than with respect to nonpayment or in respect of a provision that cannot be amended without the written consent of each Securityholder affected) or noncompliance with any provision may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Issuers, the Subsidiary Guarantors and the Trustee may amend or supplement the Indenture, the Securities or the Subsidiary Guarantees to cure any ambiguity, omission, defect, mistake or inconsistency, to comply with Article IV of the Indenture, to provide for uncertificated Securities in addition to, or in place of, certificated Securities, to add Subsidiary Guarantors with respect to the Securities, including Subsidiary Guarantors, or release a Subsidiary Guarantor from its Subsidiary Guarantee and terminate such Subsidiary Guarantee, provided that the release and termination is in accordance with the Indenture, to secure the Securities or the Subsidiary Guarantees, to add additional covenants of the Company, the Issuers or a Subsidiary Guarantor for the benefit of the Holders or to surrender any right or power conferred on the Company, the Issuers or a Subsidiary Guarantor, to comply with any requirement of the SEC in connection with qualifying the Indenture under the Act, to make any change that does not adversely affect the rights of any Securityholder, or to evidence and provide for the appointment of a successor Trustee.

A-7

12.	Defaults and Remedies

Events of Default are set forth in the Indenture. Event of Default (other than an Event of Default relating to certain bankruptcy events specified in the Indenture) occurs and is continuing, the Trustee by notice to the Company and the Issuers, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Issuers and the Trustee, may, and the Trustee at the request of such Holders shall, declare all the Securities to be due and payable immediately. If an Event of Default relating to certain bankruptcy events specified in the Indenture occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest (including Additional Interest) on all the Securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. Subject to the provisions of the Indenture relating to the duties of the Trustee if an Event of Default exists, the Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest.

13.	Trustee Dealings with the Issuers

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

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

No director, officer, employee, incorporator, stockholder, member, partner or trustee of the Company, the Co-Issuer or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company, the Co-Issuer or any Subsidiary Guarantor under the Securities, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.
