DEFINITIONS AND INCORPORATION BY REFERENCE

Section 1.1

Definitions

“144A Global Security” means a Global Security substantially in the form of Exhibit A hereto bearing the Global Security Legend and the Private Placement Legend, that has the “Schedule of Exchanges of Interests in the Global Security” attached thereto, and that is deposited with or on behalf of, and registered in the name of, the Depositary or its nominee, issued in a denomination equal to the outstanding principal amount of the Securities initially sold in reliance on Rule 144A.

“ACNTA” means (without duplication), as of the date of determination:

(1)

the sum of:

(a)

discounted future net revenue from proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with SEC guidelines before any state or federal income taxes, as estimated in a reserve report prepared as of the end of the Company’s most recently completed fiscal year, which reserve report is prepared or reviewed by independent petroleum engineers, as increased by, as of the date of determination, the discounted future net revenue of:

(i)

estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to acquisitions consummated since the date of such year-end reserve report, and

(ii)

estimated crude oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to extensions, discoveries and other additions and upward determinations of estimates of proved crude oil and natural gas reserves (including previously estimated development costs incurred during the period and the accretion of discount since the prior year end) due to exploration, development or exploitation, production or other activities which reserves were not reflected in such year-end reserve report,

in the case of the determination made under each of clauses (i) and (ii) above, calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report), and decreased by, as of the date of determination, the discounted future net revenue attributable to

(iii)

estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such year-end reserve report produced or disposed of since the date of such year-end reserve report, and

(iv)

reductions in the estimated crude oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such year-end reserve report since the date of such year-end reserve report attributable to downward determinations of estimates of proved crude oil and natural gas reserves due to exploration, development or exploitation, production or other activities conducted or otherwise occurring since the date of such year-end reserve report, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report);

provided, however, that, in the case of each of the determinations made pursuant to clauses (i) through (iv), such increases and decreases shall be as estimated by the Company’s engineers, except that if as a result of such acquisitions, dispositions, discoveries, extensions or revisions, there is a Material Change, then such increases and decreases in the discounted future net revenue shall be confirmed in writing by an independent petroleum engineer;

(b)

the capitalized costs that are attributable to crude oil and natural gas properties of the Company and its Restricted Subsidiaries to which no proved crude oil and natural gas reserves are attributed, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest annual or quarterly financial statements;

(c)

the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial statements; and

(d)

the greater of (I) the net book value on a date no earlier than the date of the Company’s latest annual or quarterly financial statements and (II) the appraised value, as estimated by independent appraisers within the immediately preceding 12 months, of other tangible assets of the Company and its Restricted Subsidiaries (provided that the Company shall not be required to obtain such an appraisal of such assets if no such appraisal has been performed);

minus

(2)

to the extent not otherwise taken into account in the immediately preceding clause (1), the sum of:

(a)

minority interests;

(b)

any net gas or other balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest audited financial statements;

(c)

the discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the same prices utilized in the Company’s year-end reserve report), attributable to reserves subject to participation interests, royalty interests, overriding royalty interests, net profits interests or other interests of third parties, pursuant to participation, partnership, vendor financing or other agreements then in effect, or which otherwise are required to be delivered to third parties;

(d)

the discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the same prices utilized in the Company’s year-end reserve report), attributable to reserves that 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 on the schedules specified with respect thereto; and

(e)

the discounted future net revenue, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production included in determining the discounted future net revenue specified in the immediately preceding clause (1)(a) (utilizing the same prices utilized in the Company’s year-end reserve report), would be necessary to satisfy fully the obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto.

If the Company changes its method of accounting from the full cost method to the successful efforts method or a similar method of accounting, ACNTA will continue to be calculated as if the Company were still using the full cost method of accounting.

The Securities shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Security or any Guarantee conflicts with the express provisions of this Indenture, the provisions of this Indenture (to the extent permitted by law) shall govern and be controlling.

Securities issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without the Global Security Legend thereon and without the “Schedule of Exchanges of Interests in the Global Security” attached thereto).

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

A Security shall not be valid until an authorized signatory of the Trustee manually 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.

The Trustee shall authenticate and deliver: (i) Initial Securities for original issue in an aggregate principal amount of $500,000,000, (ii) if and when issued, Additional Securities (which may be issued in either a registered or a private offering under the Securities Act) and (iii) Exchange Securities for issue only in an exchange offer pursuant to a Registration Rights Agreement, and only in exchange for Initial Securities or Additional Securities of an equal principal amount, in each case upon a written order of the Company signed by one Officer of the Company.

The Company may issue Additional Securities under this Indenture subsequent to the Issue Date, subject to Section 4.3 of this Indenture; provided, however, that no Additional Securities may be issued at a price that would cause such Additional Securities to have “original issue discount” within the meaning of Section 1273 of the Code; and provided, further, that in no event may the Company issue any Additional Securities if, as a result of any such issuance, the aggregate principal amount of Securities outstanding would exceed the maximum aggregate principal amount of Securities permitted under the Existing Credit Facility or any other Credit Facilities, in each case as in effect on the date of such issuance.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities. 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 such agent.

The immunities, protections and exculpations available to the Trustee under this Indenture shall also be available to each Agent, and the Company’s obligations under Section 7.7 to compensate and indemnify the Trustee shall extend likewise to each Agent.

Section 2.4

Paying Agent to Hold Money in Trust

By at least 11:00 a.m. (New York City time) on the date on which any principal, premium, if any, or interest on any Security is due and payable, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal, premium, if any, and interest when due. The Company 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 Holders or the Trustee all money held by such Paying Agent for the payment of principal, premium, if any, and interest (if any) on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money delivered to the Trustee.

Section 2.5

Transfer and Exchange

Beneficial interests in such Unrestricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Security. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in the preceding sentence of this Section 2.6(b)(1).

(2) No service charge shall be made to a holder of a beneficial interest in a Global Security or to a Holder of a Definitive Security for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge or other fee required by law and payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.9, 3.6, 3.7, 4.7 and 4.11 hereof).

(3) All Global Securities and Definitive Securities issued upon any registration of transfer or exchange of Global Securities or Definitive Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Securities or Definitive Securities surrendered upon such registration of transfer or exchange.

(4) None of the Company, the Trustee or the Registrar shall be required (A) to issue, to register the transfer of or to exchange any Securities during a period of 15 days before the day of any selection of Securities for redemption under Section 3.2 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Securities so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part or (C) to register the transfer of or to exchange a Security between a record date and the next succeeding Interest Payment Date.

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

(6) The Trustee shall authenticate Global Securities and Definitive Securities upon receipt of a written order of the Company and in accordance with the other provisions of Section 2.2 hereof.

Section 2.7

Replacement Securities

If any mutilated Security is surrendered to the Registrar or the Company and the Registrar receive evidence to their satisfaction of the destruction, loss or theft of any Security, the Company will issue and the Trustee, upon receipt of a written order of the Company conforming to Section 2.2 hereof, will authenticate a replacement Security if the Registrar’s and the Company’s reasonable requirements are met. If required by the Registrar or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Registrar, the Trustee and the Company to protect the Company, the Trustee, the Registrar, any other Agent and any Authenticating Agent from any loss that any of them may suffer if a Security is replaced.

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

Notwithstanding any other provision of this Section, rather than authenticating and delivering a replacement Security for a mutilated, destroyed, loss or stolen Security which has been redeemed or the principal of which has matured, the Company or the Paying Agent may make payment of the amount due on such security to the Holder upon receipt of the above-described indemnity bond.

Section 2.8

Outstanding Securities

The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 11.6 hereof, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.7 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected purchaser.

If the principal amount of any Security is considered paid under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue.

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

Section 2.9

Temporary Securities

Until Definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Securities in exchange for temporary Securities. Holders of temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a holder of Definitive Securities.

Section 2.10

Cancellation

The Company at any time may deliver Securities to the Trustee or any Registrar 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 or the Registrar and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment, replacement or cancellation and deliver a certificate of such destruction to the Company unless the Company directs the Trustee and the Registrar to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee or the Registrar for cancellation.

Section 2.11

Defaulted Interest

If the Company defaults in a payment of interest (“Defaulted Interest”) on the Securities, the Company shall pay Defaulted Interest (as provided in Section 4.1) in any lawful manner. The Company may pay the Defaulted Interest to the Persons who are Holders on a subsequent

special record date. The Company shall fix or cause to be fixed (or upon the Company’s failure to do so the Trustee shall fix pursuant to a written instruction of Holders of at least a majority in principal amount of the Securities) any such special record date and payment date to the reasonable satisfaction of the Trustee which special record date shall not be less than 10 days prior to the payment date for such Defaulted Interest and the Company, or at the Company’s request, the Trustee, shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the payment date and the amount of Defaulted Interest to be paid. The Company 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, and at the same time the Company 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 so deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this Section 2.11.

The Company in issuing the Securities may use “CUSIP,” “ISIN” or similar numbers (if then generally in use) and, if so, the Trustee shall use such numbers in notices of redemption 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 and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.

ARTICLE III

REDEMPTION

Section 3.1

Notices to Trustee

If the Company elects to redeem Securities pursuant to Section 3.7 hereof, it shall notify the Trustee in writing of the Redemption Date and the principal amount of Securities to be redeemed.

The Company shall give each notice to the Trustee and the Registrar provided for in this Section 3.1 at least 60 days before the Redemption Date unless the Trustee consents to a shorter period. If such redemption is to be effected pursuant to Section 3.7(b), then such notice shall be accompanied by an Officers’ Certificate to the effect that such redemption will comply with the conditions therein. If fewer than all the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Company and set forth in the related notice given to the Trustee, which record date shall be not less than 15 days after the date of such notice.

Section 3.2

Selection of Securities to Be Redeemed

In the case of any partial redemption, selection of the Securities for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed or, if the Securities are not listed, then on a

pro rata basis and in such manner as complies with applicable legal requirements. The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them the Trustee selects shall be in minimum amounts of $2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed. The Trustee may rely upon information provided by the Registrar for purposes of this Section 3.2.

Section 3.3

Notice of Redemption

At least 30 days but not more than 60 days before a date for redemption of Securities, the Company shall mail a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered address.

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

(1) the Redemption Date;

(2) the Redemption Price (if then determined and otherwise the basis for its determination);

(3) the name and address of the Paying Agent where Securities are to be surrendered;

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

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

(6) that, unless the Company defaults in making such redemption payment, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the Redemption Date;

(7) the CUSIP, ISIN or similar number, if any, printed on the Securities being redeemed; and

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

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section 3.3.

Section 3.4

Effect of Notice of Redemption

Once notice of redemption is mailed to Holders, Securities (or portions thereof) called for redemption become irrevocably due and payable on the Redemption Date and at the Redemption Price. A notice of redemption may not be conditional. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price stated in the notice, plus accrued and unpaid interest to the Redemption Date; provided that if the Redemption Date is after the taking of a record of the Holders on a record date and on or prior to the related Interest Payment Date, the accrued and unpaid interest shall be payable to the Person in whose name the redeemed Securities are registered on such record date. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

Section 3.5

Deposit of Redemption Price

No later than 11:00 a.m. (New York City time) on the Redemption Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of and accrued and unpaid interest on all Securities to be redeemed on that date. If the Company complies with the provisions of this paragraph, then on and after the Redemption Date, interest will cease to accrue on the Securities or the portions of Securities called for redemption.

Section 3.6

Securities Redeemed in Part

Upon cancellation of a Security that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered. The Trustee shall notify the Registrar of the issuance of such new Security.

Section 3.7

(a) On and after June 1, 2012, the Company may redeem all or a part of the Securities at any time or from time to time at the following Redemption Prices (expressed as percentages of the principal amount) plus accrued and unpaid interest on the Securities, if any, to the applicable Redemption Date, if redeemed during the 12-month period beginning June 1 of the years indicated:

The Company is not, however, prohibited from acquiring the Securities by means other than a redemption, whether pursuant to a tender offer, open market transactions or otherwise, so long as the acquisition does not otherwise violate the terms of this Indenture.

ARTICLE IV

The Company will pay, to the extent lawful, interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, at the rate then in effect on the Securities; it will pay, to the extent lawful, interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods), from time to time on demand at the same rate as on overdue principal.

All references in this Indenture, the Securities or the Subsidiary Guarantees to “interest” shall be deemed to include Additional Interest unless the context otherwise requires. The Company shall give the Trustee advance written notice of the amount of any Additional Interest that may be payable with respect to the Securities.

Section 4.2

SEC Reports

Whether or not required by the SEC, so long as any Securities are outstanding, the Company will furnish to the Holders of Securities, within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such Forms, including a section on “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s certified independent public accountants; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports.

If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

In addition, whether or not required by the SEC, the Company will file a copy of all of the information and reports referred to in clause (1) and (2) above with the SEC for public availability within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing).

In addition, the Company agrees that, for so long as any Securities remain outstanding, if at any time it is not required to file with the SEC the reports required by the preceding paragraphs of this Section 4.2, it will furnish to Holders of Securities and to prospective investors, upon request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Section 4.3

Incurrence of Indebtedness

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt); provided, however, that the Company and any Guarantor may incur Indebtedness (including Acquired Debt), if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred would have been at least 2.5 to 1, determined on a pro forma basis (including a pro forma application of the Net Cash Proceeds therefrom), as if the additional Indebtedness had been incurred at the beginning of such four-quarter period.

(b) The foregoing paragraph (a) of this Section 4.3 will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Indebtedness”):

(1) the incurrence by the Company and any Guarantor of the Indebtedness under Credit Facilities; provided that the aggregate principal amount of all Indebtedness of the Company and the Guarantors outstanding at any time under this clause (1) under all Credit Facilities after giving effect to such incurrence does not exceed an amount equal to the greater of (A) $1.0 billion less the aggregate amount of all permanent principal repayments since the Issue Date under a Credit Facility that are made under clause (b)(1) of Section 4.7 hereof and (B) 30% of ACNTA as of the date of such incurrence;

(2) the incurrence by the Company and its Restricted Subsidiaries of Existing Indebtedness (other than Indebtedness described under clause (1), (3) or (6) of this paragraph (b));

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by (A) the Initial Securities and the Subsidiary Guarantees, and (B) any Securities issued pursuant to the Registration Rights Agreement in exchange for the Securities, and any Subsidiary Guarantees related thereto;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Non-Recourse Purchase Money Indebtedness;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the Net Cash Proceeds of which are used to refund, refinance or replace, Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under paragraph (a) of this Section 4.3 covenant or clause (2), (3), (4) or this clause (5) of this paragraph (b);

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

(A)(i) if the Company is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations with respect to the Securities, and (ii) if a Guarantor is the obligor of such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations of such Guarantor with respect to its Subsidiary Guarantee, and

(B)(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary thereof and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary thereof, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause;

(7) in-kind obligations relating to net oil and natural gas balancing positions arising in the ordinary course of business;

(8) the accrual of interest accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock, in the form of additional shares of the same class of Disqualified Stock;

(9) any obligations in respect of completion bonds, performance bonds, bid bonds, appeal bonds, surety bonds, bankers acceptances, letters of credit, insurance obligations or bonds and other similar bonds and obligations incurred by the Company or any Restricted Subsidiary in the ordinary course of business and any guaranties or letters of credit functioning as or supporting any of the foregoing bonds or obligations;

(10) any obligation (including deferred premiums) under Interest Rate Agreements, Currency Agreements and Commodity Agreements; provided, that such Interest Rate Agreements, Currency Agreements and Commodity Agreements are related to business transactions of the Company or its Restricted Subsidiaries and are entered into for bona fide hedging purposes of the Company or its Restricted Subsidiaries (as determined in good faith by the Board of Directors or senior management of the Company);

(11) any obligation arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, guarantee, adjustment of purchase price, holdback, contingency payment obligation based on the performance of the acquired or disposed asset or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, asset or Capital Stock of a Restricted Subsidiary;

(12) any obligation arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five Business Days of incurrence; and

(13) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in addition to Indebtedness permitted by clauses (1) through (12) above of this paragraph (b) or the first paragraph (a) of this Section 4.3 above in an aggregate principal amount (or accrued value, as applicable) at any time outstanding not to exceed $45.0 million.

(1) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (13) of paragraph (b) above, or is entitled to be incurred pursuant to paragraph (a) of this Section 4.3, the Company will be permitted to classify such item of Indebtedness (or any portion thereof) on the date of its incurrence in any manner that complies with this covenant, and only be required to include the amount and type of such Indebtedness in one of such clauses;

(2) all Indebtedness outstanding on the date of this Indenture under the Credit Facilities shall be deemed initially incurred on the Issue Date under clause (1) of paragraph (b) of this Section 4.3 and not paragraph (a) of this Section 4.3 or clause (2) of paragraph (b) of this Section 4.3;

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

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

(5) Indebtedness permitted by this covenant 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 covenant permitting such Indebtedness;

(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; and

(7) Indebtedness of any Person existing at the time such Person becomes a Restricted Subsidiary shall be deemed to have been incurred by the Company and the Restricted Subsidiary at the time such Person becomes a Restricted Subsidiary.

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

Section 4.4

Restricted Payments

(1) no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;

(2) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.3(a) hereof; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after July 12, 2006 (excluding Restricted Payments permitted by clauses (2), (3), (4), (6), (7), (9), (11) and (12) of the next succeeding paragraph (c) below, but including Restricted Payments permitted by clauses (1), (5), (8) and (10) of such paragraph), is less than the sum, without duplication, of

(A) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from July 1, 2006 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus

(C) the amount by which Indebtedness is reduced on the Company’s consolidated balance sheet upon the conversion or exchange (other than by a Subsidiary of the Company) subsequent to July 12, 2006 of any Indebtedness convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company (plus the amount of any accrued interest then outstanding on such Indebtedness to the extent the obligation to pay such interest is extinguished less the amount of any cash, or the Fair Market Value of any property (as determined in good faith by an Officer of the Company), distributed by the Company upon such conversion or exchange); provided, however, that the foregoing amount shall not exceed the Net Cash Proceeds received by the Company or any Restricted Subsidiary from the sale of such Indebtedness (excluding Net Cash Proceeds from sales to a Subsidiary of the Company or to an employee stock ownership plan or to a trust established by the Company or any of its Subsidiaries for the benefit of their employees); plus

The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued at the time of such Restricted Payment by this covenant shall be evidenced by an Officers’ Certificate which shall be delivered to the Trustee not later than five Business Days following the date of the making of any Restricted Payment. Such Officers’ Certificate shall state that such Restricted Payment is permitted by this Section 4.4, together with a copy of any related resolution of the Board of Directors.

For purposes of determining compliance with this Section 4.4, if a Restricted Payment meets the criteria of more than one of the types of Restricted Payments described in clauses (1)-(12) above, the Company, in its sole discretion, may order and classify such Restricted Payment in any manner in compliance with this covenant.

In computing Consolidated Net Income under clause (b)(3)(A) above, (1) the Company shall use audited financial statements for the portions of the relevant period for which audited financial statements are available on the date of determination and unaudited financial statements and other current financial data based on the books and records of the Company for the remaining portion of such period and (2) the Company shall be permitted to rely in good faith on the financial statements and other financial data derived from the books and records of the Company that are available on the date of determination.

Section 4.5

Liens

The Company will not, and will not permit any of its Restricted Subsidiaries to create, incur, assume or suffer to exist any Lien on any property or asset now owned or hereafter

acquired, or any income or profits therefrom or assign or convey any right to receive income therefrom, except Permitted Liens, to secure (a) any Indebtedness of the Company unless prior to, or contemporaneously therewith, the Securities are equally and ratably secured for so long as such other Indebtedness is so secured, or (b) any Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary Guarantee of such Guarantor is equally and ratably secured for so long as such other Indebtedness is so secured; provided, however, that if such Indebtedness is expressly subordinated to the Securities or a Subsidiary Guarantee, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Securities or such Subsidiary Guarantee, as the case may be, with the same relative priority as such Indebtedness has with respect to the Securities or such Subsidiary Guarantee.

Section 4.6

Dividend and Other Payment Restrictions Affecting Subsidiaries

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

(2) make loans or advances to the Company or any of the Company’s Restricted Subsidiaries; or

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

Section 4.7

Asset Sales

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

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the Equity Interests or other assets issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash:

(A) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the

Securities or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement or similar agreement that releases the Company or such Restricted Subsidiary from further liability; and

(B) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted within 120 days by the Company or such Restricted Subsidiary into cash (to the extent of the cash received in that conversion).

(b) Within the later of (x) one year after the date of receipt of any Net Proceeds from an Asset Sale and (y) six months after the date of an agreement entered into within such one-year period committing the Company to make an acquisition or expenditure referred to in clauses (2) or (3) below, the Company may apply such Net Proceeds at its option, in any one or more of the following:

(1) to permanently repay, prepay, redeem or repurchase the Senior Debt of the Company or any Guarantor, and cause any related loan commitment to be permanently reduced in an amount equal to the principal amount so repaid, prepaid, redeemed or repurchased;

(2) to acquire all or substantially all of the assets of, or a majority of the Voting Stock of, a Company principally engaged in the Oil and Gas Business or to acquire additional Capital Stock in any Person that at such time is a Restricted Subsidiary; or

(3) to make capital expenditures or to acquire properties or assets, in each case that are used or useful in the Oil and Gas Business.

Pending the final application of any such Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture.

(c) Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will make an offer (the “Asset Sale Offer”) to all Holders of Securities and, to the extent required by the terms thereof, all holders of other Indebtedness that is pari passu with the Securities containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Securities and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount (or accreted value in the case of any such other pari passu Indebtedness issued with a significant original issue discount) plus accrued and unpaid interest, if any, to the date of purchase (the “Asset Sale Payment”), and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities and such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Securities and such other pari passu Indebtedness to be purchased on a pro rata basis, on the basis of the aggregate principal amounts (or accreted values) tendered in round denominations (which in the

case of the Securities will be minimum denominations of $2,000 principal amount or multiples of $1,000 in excess thereof). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(d) Within 30 days following the date when the Company becomes obligated to make an Asset Sale Offer, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Asset Sale and offering to repurchase Securities on the date (the “Asset Sale Payment Date”) specified in such notice, which date will be no earlier than 30 days nor later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice.

(e) On the Asset Sale Payment Date, the Company will, to the extent lawful:

(1) accept for payment all Securities or portions thereof properly tendered pursuant to the Asset Sale Offer, subject to proration based on the amount of Excess Proceeds pursuant to clause (c) above of this Section 4.7;

(2) deposit with the Paying Agent an amount equal to the amount of Excess Proceeds that, after giving effect to proration with holders of pari passu Indebtedness pursuant to clause (c) above of this Section 4.7, is allocable to the Securities or portions thereof so tendered (or, if less, the aggregate Asset Sale Payment for all Securities validly tendered and not withdrawn); 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 thereof being purchased by the Company.

(f) The Paying Agent will promptly mail (or cause to be transferred through the facilities of the Depositary) to each Holder of Securities so tendered and not withdrawn and accepted for payment in accordance with this Section 4.7, the Asset Sale Payment for such tendered Securities, and the Trustee 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, by such Holder; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple thereof.

(g) If the Asset Sale Offer Purchase Date is after the taking of a record of the Holders on a record date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a purchased Security is registered on such record date, and no other interest will be payable to Holders who tender Securities pursuant to the Asset Sale Offer.

(h) The Company will comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.7, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of the Company’s compliance with such securities laws or regulations.

(i) The Company will publicly announce the results of the Asset Sale Offer on or as soon as practicable after the date such Asset Sale Offer is completed.

Section 4.8

Transactions With Affiliates

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

(1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained at the time of such transaction in arm’s-length dealings by the Company or such Restricted Subsidiary with a Person who is not an Affiliate; and

(2) (A) with respect to any Affiliate Transaction or series of related Affiliate(s) Transactions involving aggregate consideration in excess of $10.0 million, a majority of the disinterested members of the Board of Directors have determined that the criteria set forth in clause (a)(1) of this Section 4.8 are satisfied with respect to such Affiliate Transaction(s) and have approved such Affiliate Transaction(s), as evidenced by a Board Resolution delivered to the Trustee and certified by an Officers’ Certificate as having been adopted by the Board of Directors; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, the Company delivers to the Trustee a written opinion that such Affiliate Transaction(s) is fair, from a financial point of view, to the Company and its Restricted Subsidiaries, taken as a whole, or that such Affiliate Transaction(s), is not less favorable to the Company and its Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who is not an Affiliate, in either such case issued by an accounting, appraisal or investment banking firm of national standing that is not an Affiliate of the Company.

(b) The following items shall not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.8(a) hereof:

(1) any employment agreement or other employee compensation plan or arrangement existing on the Issue Date or thereafter entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and consistent with the past practice of the Company or such Restricted Subsidiary;

(2) transactions between or among the Company and/or its Restricted Subsidiaries;

(3) Restricted Payments that, in each case, are permitted by Section 4.4 hereof;

(4) loans or advances to employees, officers or directors in the ordinary course of business of the Company or any of its Restricted Subsidiaries, in each case only as permitted by Section 402 of the Sarbanes-Oxley Act of 2002, but in any event not to exceed $1.0 million in the aggregate outstanding at any one time;

(5) indemnities of officers, directors and employees of the Company or any Restricted Subsidiary consistent with applicable charter, bylaw or statutory provisions; and

(6) the payment of reasonable and customary fees to directors of the Company or any of its Restricted Subsidiaries who are not employees of the Company or any Subsidiary.

Section 4.9

Additional Subsidiary Guarantees

If the Company or any of its Restricted Subsidiaries acquires or creates another Restricted Subsidiary (other than Foreign Subsidiaries) on or after the Issue Date, then the Company shall cause that newly acquired or created Restricted Subsidiary (i) to become a Guarantor by executing a supplemental indenture substantially in the form of Exhibit E hereto and (ii) to deliver an Opinion of Counsel to the Trustee as to the due authorization, execution and delivery thereof by such Guarantor.

Section 4.10

Business Activities

The Company will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material in the opinion of the Board of Directors (which opinion shall be reasonable and made in good faith) to the Company and its Restricted Subsidiaries taken as a whole.

Section 4.11

Change of Control

(a) If a Change of Control occurs, each Holder of Securities 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 that Holder’s Securities pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Company will offer a payment (the “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of Securities to be repurchased plus accrued and unpaid interest thereon, if any, to the date of purchase. Within 30 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Securities on the date (the “Change of Control Payment Date”) specified in such notice, which date will be no earlier than 30 days nor later than 60 days from the date such notice is mailed, pursuant to the procedures required by this Indenture and described in such notice. The Company will comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of the covenant described herein, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue of the Company’s compliance with such securities laws or regulations.

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

(1) accept for payment all Securities or portions thereof properly tendered pursuant to the Change of Control Offer;

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

(c) The Paying Agent will promptly mail (or cause to be transferred through the facilities of the Depositary) to each Holder of Securities so tendered and not withdrawn the Change of Control Payment for such tendered Securities, and the Trustee 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, by such Holder; provided that each such new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Trustee will notify the Registrar of the issuance of the new Security.

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

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

(f) The provisions described above that require the Company to make a Change of Control Offer following a Change of Control will be applicable regardless of whether or not any other provisions of this Indenture are applicable.

(g) The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer.

Section 4.12

Maintenance of Office or Agency for Registration of Transfer, Exchange and Payment of Securities

So long as any of the Securities shall remain outstanding, the Company will, in accordance with Section 2.3 hereof, maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, or the Registrar) in the continental United States where the Securities may be surrendered for exchange or registration of transfer as in this Indenture provided and where notices and demands to or upon the Company in respect to the Securities

may be served, and in the City of New York, State of New York, where the Securities may be presented or surrendered for payment. The Company may also from time to time designate one or more other offices or agencies in the continental United States, either within or without the City of New York, the State of New York, where Securities may be presented or surrendered for any and all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation under Section 2.3 and this Section 4.12 to maintain an office or agency in the City of New York, State of New York where Securities may be presented or surrendered for payment. The Company will give to Trustee prompt written notice of the location of any such office or agency and of any change of location thereof. In case the Company shall fail to maintain any such office or agency or shall fail to give such notice of the location or of any change in the location thereof, such surrenders, presentations and demands may be made and notices may be served at the designated Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee its agent to receive at the aforesaid office all such surrenders, presentations, notices and demands.

Section 4.13

Appointment to Fill a Vacancy in the Office of Trustee

(1) that it will hold all sums held by it as such agent for the payment of the principal of, premium, if any, or interest on the Securities (whether such sums have been paid to it by the Company or by any other obligor on the Securities) in trust for the benefit of the Holders of the Securities and will notify the Trustee of the receipt of sums to be so held;

(2) that it will give the Trustee notice of any failure by the Company (or by any other obligor on the Securities) to make any payment of the principal of, premium, if any, or interest on the Securities when the same shall be due and payable;

(3) that it will at any time during the continuance of any Event of Default specified in Section 6.1, upon the written request of the Trustee, deliver to the Trustee all sums so held in trust by it; and

(4) that it will acknowledge, accept and agree to comply in all aspects with the provisions of this Indenture relating to the duties, rights and liabilities of such Paying Agent.

(b) If the Company shall not act as its own Paying Agent, it will, by 11:00 a.m. (New York City time) on the due date of the principal of or premium, if any, or interest on any Securities, deposit with such Paying Agent a sum in same day funds sufficient to pay the

principal of, premium, if any, or interest so becoming due, such sum to be held in trust for the benefit of the Holders of Securities entitled to such principal of or premium, if any, or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its failure so to act.

(c) If the Company shall act as its own Paying Agent, it will, by 11:00 a.m., (New York City time) on each due date of the principal of or premium, if any, or interest on the Securities, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto, a sum sufficient to pay such principal or premium or interest so becoming due and will notify the Trustee of any failure to take such action.

(d) Anything in this Section 4.14 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Paying Agent for delivery to the Trustee all sums held in trust by it, as required by this Section 4.14, such sums to be delivered by the Paying Agent to the Trustee to be held by the Trustee upon the trusts herein contained.

(e) Anything in this Section 4.14 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.14 is subject to the provisions of Section 8.4 and Section 8.6.

Section 4.15

Maintenance of Corporate Existence

So long as any of the Securities shall remain outstanding, the Company will at all times (except as otherwise provided or permitted in this Article V of this Indenture) do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

Section 4.16

Compliance Certificate

(a) The Company and the Guarantors shall deliver to the Trustee within 90 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 the principal executive officer, the principal accounting officer or the principal financial officer of each of the Company and the Guarantors, 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 Company and the 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 Company is taking or proposes to take with respect thereto.

(b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements delivered pursuant to Section 4.2 above shall be accompanied by a written statement of the Company’s independent public accountants that in making the examination necessary for certification of such financial statements, nothing has come to their attention that would lead them to believe that the Company has violated any provisions of this Article IV or Article V hereof or, if any such violation has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation.

(c) So long as any of the Securities are outstanding, the Company will deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

Section 4.17

Taxes

The Company will pay, and will cause each of its Significant Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment would not have a material adverse effect on the Company and its Restricted Subsidiaries, taken as a whole.

Section 4.18

Stay, Extension and Usury Laws

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

ARTICLE V

SUCCESSOR COMPANY

Section 5.1

Merger, Consolidation or Sale of Assets

(a) The Company may not: (1) consolidate or merge with or into another Person (whether or not the Company is the surviving corporation); or (2) sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as whole, in one or more related transactions, to another Person, unless:

(1) either:

(A) the Company is the surviving corporation; or

(B) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a Person organized or existing under the laws of the United States, any state thereof or the District of Columbia;

(2) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Securities, this Indenture and each Registration Rights Agreement pursuant to a supplemental indenture reasonably satisfactory to the Trustee;

(3) immediately after such transaction no Default or Event of Default exists;

(4) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company) will, 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, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.3(a) hereof; and

(5) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and such supplemental indenture (if any) comply with this Indenture.

ARTICLE VI

Each of the following is an “Event of Default”:

(1) default for 30 days in the payment when due of interest on the Securities;

(2) default in the payment when due of the principal of, or premium, if any, on the Securities;

(3) failure by the Company to comply with Section 5.1 hereof;

(4) failure by the Company or any of its Restricted Subsidiaries to comply for 30 days after receipt of written notice specified below with Sections 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 4.10 or 4.11 hereof;

(5) failure by the Company for 60 days after receipt of written notice specified below to comply with any of its other agreements contained in this Indenture;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, if that default:

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

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

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10.0 million or more; provided, however, that if any such Payment Default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such Payment Default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Securities shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree;

(7) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $10.0 million (net of any amounts covered by insurance), which judgments are not paid, discharged or stayed for a period of 60 days;

(8) any Subsidiary Guarantee of a Guarantor shall be held in any judicial proceeding to be unenforceable or invalid or, except as permitted by this Indenture, shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee, in each case with respect to any Guarantor that is also a Significant Subsidiary or any group of Guarantors that, taken together, would constitute a Significant Subsidiary; and

(9) (A) the Company or a Significant Subsidiary or a group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(i) commences a voluntary case or proceeding;

(ii) consents to the entry of an order for relief against it in an involuntary case or proceeding in which it is a debtor;

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property;

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

(v) consents to the institution of a bankruptcy or an insolvency proceeding against it;

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

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

(i) is for relief against the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary in an involuntary case in which it is a debtor;

(ii) appoints a Custodian of the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for any substantial part of its property; or

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

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 Company of the Default and the Company does not cure such

Default within the time specified in clauses (4) and (5) of this Section 6.1 after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

Section 6.2

Acceleration of Maturity; Rescission and Annulment

If an Event of Default (other than an Event of Default described in clause (9) of Section 6.1) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Securities to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest will be due and payable immediately. If an Event of Default described in clause (9) of Section 6.1 above occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Securities will become and be immediately due and payable without any further action or notice on the part of the Trustee or any Holders. The Holders of a majority in outstanding principal amount of the Securities by notice to the Trustee may on behalf of the Holders of all the Securities rescind any such acceleration with respect to the Securities and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Securities that have become due solely by such declaration of acceleration, 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 to collect the payment of principal of, premium (if any) or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder 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 to the extent permitted by law.

Section 6.4

Waiver of Past Defaults

The Holders of a majority in outstanding principal amount of the Securities, by notice to the Trustee may on behalf of the Holders of all the Securities waive an existing Default or Event of Default and its consequences hereunder except (i) a Default or Event of Default in the payment of the principal of, premium, if any, or interest on a Security or (ii) a Default or Event of Default in respect of a provision that under Section 9.2 hereof cannot be amended without the consent of each Holder affected. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

Section 6.5

Control by Majority

The Holders of a majority in outstanding principal amount of the Securities have the right to direct the time, method and place of conducting any proceeding for exercising 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 or, subject to Section 7.1 hereof, that the Trustee determines is unduly prejudicial to the rights of other Holders 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. Subject to Section 7.1, prior to taking any action hereunder, the Trustee shall be entitled to indemnification reasonably satisfactory to it against all loss, liability and expense caused by taking or not taking such action.

Section 6.6

Limitation on Suits

Except to enforce the right to receive payment of principal, premium (if any) or interest when due, a Holder may not pursue any remedy with respect to this Indenture, the Securities or the Subsidiary Guarantees unless:

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

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

(3) such Holder or Holders have furnished the Trustee reasonable security or indemnity against any loss, liability or expense;

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

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

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

Section 6.7

Rights of Holders to Receive Payment

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, and interest on the Securities held by such Holder, on or after the respective due dates expressed 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.

Section 6.8

Collection Suit by Trustee

If an Event of Default specified in Section 6.1(1) or Section 6.1(2) hereof occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any Guarantor 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 hereof to cover the costs and expenses of collection, including the reasonable compensation, disbursement and advances of the Trustee, its agents and counsel.

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 and the Holders allowed in any judicial proceedings relative to the Company or any Guarantor or their respective creditors or properties and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.7 hereof.

Section 6.10

Priorities

If the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money or property in the following order:

First: costs and expenses of collection, including all sums paid or advanced by the Trustee hereunder and the compensation, expenses and disbursements of the Trustee, its agents, and counsel and all other amounts due to the Trustee under Section 7.7 hereof;

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

Third: to the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Holder and the Company a notice that states the record date, the payment date and amount to be paid.

Section 6.11

Undertaking for Costs

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit,

and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 hereof 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

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

Section 7.2

Rights of Trustee.

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

(f) Except for (i) a default under Section 6.1(1) or Section 6.1(2) hereof, or (ii) any other event of which the Trustee has actual knowledge and which event, with the giving of notice or the passage of time or both, would constitute an Event of Default under this Indenture, the Trustee shall not be deemed to have notice of any default or event unless specifically notified in writing of such event by the Company or any Holder of the Securities.

(g) The Trustee shall have no obligation to ascertain whether or not the Company is obligated at any time to offer to purchase the Securities pursuant to Section 4.7 or 4.11 hereof, and at all times the Trustee may conclusively presume, in the absence of written notice to the contrary from the Company or an order from a court of competent jurisdiction, that no such obligation exists.

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 Company or its Affiliates with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA) after a Default has occurred and is continuing, it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee or resign. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.4

Trustee’s Disclaimer

Section 7.5

Notice of Defaults

If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall mail to each Holder notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default relating to payment of principal of, premium, if any, or interest on, any Security (including payments pursuant to the redemption or required repurchase provisions of such Security), the Trustee may withhold the notice if and so long as its board of directors, the Executive Committee of its board of directors or a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders.

Section 7.6

Reports by Trustee to Holders

(a) Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report that complies with Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act §313(a) has occurred within the 12 months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with Trust Indenture Act Section 313(b). The Trustee shall also transmit by mail all reports required by Trust Indenture Act Section 313(c).

(b) A copy of each report at the time of its mailing to Holders shall be mailed to the Company and 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.

Section 7.7

Compensation and Indemnity

(a) The Company shall pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for its services, which may be set forth in a separate fee agreement between the Trustee and the Company. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Holders and reasonable costs of counsel retained by the Trustee in connection with the delivery of an Opinion of Counsel or

otherwise, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents and counsel. The Company shall indemnify and hold harmless the Trustee (in its individual and trustee capacities) and its officers, directors and agents against any and all loss, liability, claims, action, suit, cost or expense (including reasonable attorneys’ fees) of any kind and nature whatsoever incurred by it in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including this Section 7.7) and of defending itself against any claims (whether asserted by any Holder, the Company or otherwise). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company is not required to reimburse any expense or indemnify against any loss, liability claim, again, suit, cost or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence.

(b) To secure the Company’s 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.

(c) The Company’s payment obligations pursuant to this Section 7.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.1(9) hereof with respect to the Company, the expenses are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.8

Replacement of Trustee

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.8.

The Company may remove the Trustee if: (i) the Trustee fails to comply with Section 7.10 hereof; (ii) the Trustee is adjudged bankrupt or insolvent; (iii) a Custodian or other public officer takes charge of the Trustee or its property; or (iv) the Trustee otherwise becomes incapable of acting.

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 hereof.

(f) If the Trustee fails to comply with Section 7.10 hereof after written notice thereto, the Holders of at least 10% in principal amount of the then outstanding Securities may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(g) Notwithstanding the replacement of the Trustee pursuant to this Section 7.8, the Company’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee.

Section 7.9

Successor Trustee by Merger

(a) 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 or banking association without any further act shall be the successor Trustee.

(b) If 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 if at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

Section 7.10

Eligibility; Disqualification

The Trustee shall at all times satisfy the requirements of Trust Indenture Act Section 310(a). There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act Section 310(b); provided, however, that there shall be excluded from the operation of Trust Indenture Act Section 310(b)(1) the indenture for the 7.875% Senior Notes

due 2013 of the Company and any other indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Trust Indenture Act Section 310(b)(1) are met.

Section 7.11

Preferential Collection of Claims Against Company

The Trustee shall comply with Trust Indenture Act Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated.

(b) Subject to Section 8.2 hereof, the Company at its option at any time may terminate (i) all its obligations, except as specified in Section 8.1(c) hereof, under the Securities and this Indenture and all obligations of the Guarantors with respect to their Subsidiary Guarantees (“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 Section 4.2, Section 4.3, Section 4.4, Section 4.5, Section 4.6, Section 4.7, Section 4.8, Section 4.9, Section 4.10 and Section 4.11 hereof, except to the extent such obligations are imposed by Section 318(c) of the Trust Indenture Act, and clause (a)(4) of Section 5.1 hereof, and the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or by reason of any reference in any such Section to any other provision herein or in any other document and such omission to comply with such Sections shall no longer constitute a Default or an Event of Default under Section 6.1(3) (solely as it relates to clause (a)(4) of Section 5.1) and Section 6.1(4) hereof and the operation of Section 6.1(5), Section 6.1(6), Section 6.1(7) and Section 6.1(8) hereof and (with respect only to Significant Subsidiaries) Section 6.1(9) hereof, and the events specified in such Sections shall no longer constitute an Event of Default (this clause (ii) being referred to as the “covenant defeasance option”), but otherwise the remainder of this Indenture and the Securities shall be unaffected thereby. The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option or its covenant defeasance option, each Guarantor shall be released from its obligations with respect to its Subsidiary Guarantee as provided in Section 10.9(b) hereof.

If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default.

(6) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;

With Consent of Holders

The Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Securities or the Subsidiary Guarantees with the consent of the Holders of at least a majority in principal amount of the then outstanding Securities (including consents obtained in connection with the purchase of, or tender offer or exchange offer for, Securities). Subject to the following sentence, any existing Default or compliance with any provision 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 then outstanding Securities (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). However, without the consent of each Holder, an amendment, supplement or waiver may not (with respect to any Securities held by a non-consenting Holder):

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

(2) reduce the principal of or change the fixed maturity of any Security or alter the provisions with respect to the redemption or repurchase of the Securities (other than provisions relating to Section 4.7 or 4.11);

(3) reduce the rate of or change the time for payment of interest on any Security;

(4) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Securities or a Default or Event of Default in respect of a provision that cannot be amended or supplemented without the consent of each Holder affected;

(5) make any Security payable in a currency other than that stated in the Securities;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Securities to receive payments of principal of or premium, if any, or interest on the Securities (except as permitted by clause (7) below);

(7) waive a redemption or repurchase payment with respect to any Security (other than a payment required by Section 4.7 or 4.11);

(8) modify any Subsidiary Guarantee in any manner adverse to the Holders of the Securities or release any Guarantor from its obligations under its Subsidiary Guarantee except in accordance with the terms of this Indenture;

(9) make any change in the ranking of the Securities or the Subsidiary Guarantees in a manner adverse to the Holders of the Securities or the Subsidiary Guarantees; or

(10) make any change in the preceding amendment, supplement and waiver provisions of this Section 9.2.

The consent of the Holders is not necessary under this Section 9.2 to approve the particular form of any proposed amendment or waiver. It is sufficient if the consent approves the substance of the proposed amendment or waiver.

After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company shall mail to each Holder of Securities affected thereby a notice briefly describing such amendment. The failure to give such notice to any or all Holders, or any defect therein, shall not impair or affect the validity of any amendment, supplement or waiver under this Section 9.2.

Section 9.3

Compliance with Trust Indenture Act

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

Section 9.4

Revocation and Effect of Consents and Waivers

A consent to an amendment, supplement or 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 (or any Holder of a Security issued upon the registration of transfer or exchange thereof or in lieu thereof), even if notation of the amendment, supplement or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Security or portion of the Security if the Trustee receives the written notice of revocation before the date the amendment, supplement or waiver becomes effective. After an amendment, supplement or waiver becomes effective in accordance with its terms, it shall bind every Holder.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders 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 Holders at the close of business on 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, and for this purpose the Securities then outstanding shall be computed as of 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 or supplement 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 Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms, but the failure to make the appropriate notation or to issue a new Security shall not affect the validity and effect of such amendment or supplement.

Section 9.6

Trustee to Sign Amendments

The Trustee shall sign any amendment or supplement authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment or supplement the Trustee shall be entitled to receive, and (subject to Section 7.1 hereof) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplement is authorized or permitted by this Indenture.

ARTICLE X

SUBSIDIARY GUARANTEES

Section 10.1

Subsidiary Guarantees

Each Guarantor which is a party hereto or becomes a party hereto by executing and delivering a supplement to this Indenture pursuant to Section 4.9 hereof, jointly and severally, unconditionally Guarantees to each Holder and to the Trustee and its successors and assigns the full and punctual payment of principal of, premium (if any) and interest on the Securities when due, whether at Stated Maturity, or upon redemption, required repurchase pursuant to Section 4.7 or Section 4.11 hereof, acceleration or otherwise, and all other monetary obligations owing by the Company under this Indenture (including obligations owing to the Trustee) and the Securities (all the foregoing being hereinafter collectively called the “Obligations”). The Guarantors further agree that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from the Guarantors, and that the Guarantors will remain bound under this Article X notwithstanding any extension or renewal of any Obligation.

The Guarantors waive presentation to, demand of payment from and protest to the Company of any of the Obligations and also waive notice of protest for nonpayment. The Guarantors waive notice of any Default under the Securities or the Obligations. The obligations of the Guarantors hereunder shall not be affected by: (i) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other agreement or otherwise; (ii) any extension or renewal of any Obligation; (iii) any rescission, waiver, amendment, modification or supplement of any of the terms or provisions of this Indenture (other than this Article X), the Securities or any other agreement; (iv) the release of security, if any, held by any Holder or the Trustee for the Obligations or any of them; (v) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Obligations; (vi) any change in the ownership of the Company; or (vii) 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 the Guarantors or would otherwise operate as a discharge of the Guarantors as a matter of law or equity, except for payment of the Securities in full.

The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees herein constitute a guarantee of payment when due (and not a guarantee of collection) and waive any right to require that any resort be had by any Holder or the Trustee to security, if any, held for payment of the Obligations.

The obligations of the Guarantors hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (except to the extent provided in Section 10.2 hereof), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense, setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise.

The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against the Guarantors by virtue hereof, upon the failure of the Company to pay any Obligation when and as the same shall become due, whether at Stated Maturity, upon redemption, required repurchase, acceleration or otherwise, the Guarantors hereby promise to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Obligations, (ii) accrued and unpaid interest on such Obligations (but only to the extent not prohibited by law) and (iii) all other monetary Obligations of the Company to the Holders and the Trustee.

The Guarantors, jointly and severally, agree that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Obligations may be accelerated as provided in Article VI for the purposes of the Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article VI, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purposes of this Section 10.1.

The Guarantors, jointly and severally, also agree to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.1.

Section 10.2

Limitation on Liability

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

Section 10.3

Execution and Delivery of Subsidiary Guarantee

To evidence its Subsidiary Guarantee set forth in Section 10.1, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as Exhibit D hereto will be endorsed by manual or facsimile signature by an Officer of such Guarantor on each Security authenticated and delivered by the Trustee and that this Indenture (or a supplemental indenture substantially in form of Exhibit E hereof) will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.1 will remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Subsidiary Guarantee. If an Officer whose facsimile signature is on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Security on which the Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless.

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

In the event that the Company or any of its Restricted Subsidiaries acquires or creates another Restricted Subsidiary (other than Foreign Subsidiaries) after the Issue Date, the Company will comply with the provisions of Section 4.9 hereof.

Section 10.4

Successors and Assigns

Except as otherwise provided in Section 10.9 hereof, this Article X shall be binding upon the Guarantors and their successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights in accordance with the terms of this Indenture by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture, the Securities and the Subsidiary Guarantees.

Section 10.5

No Waiver

Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article X shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article X at law, in equity, by statute or otherwise.

Section 10.6

Right of Contribution

Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor hereunder who has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and conditions of this Article X. The provisions of this Section 10.6 shall in no respect limit the obligations and liabilities of any Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Guarantor hereunder.

Section 10.7

No Subrogation

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

Section 10.8

Modification

No modification, amendment or waiver of any provision of this Article X, nor the consent to any departure by the Guarantors therefrom, shall in any event be effective unless the same shall be made in accordance with Article IX hereof. No notice to or demand on the Guarantors in any case shall entitle the Guarantors to any other or further notice or demand in the same, similar or other circumstances.

Section 10.9

Merger, Consolidation or Sale of Assets of a Guarantor; Release of a Guarantor

(a) The Company shall not permit a Guarantor to sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the resulting, transferee or surviving Person), another Person (other than the Company or another Guarantor), unless:

(1) immediately after giving effect to that transaction, no Default or Event of Default shall have occurred and be continuing; and

(2) either:

(A) the Person acquiring the properties or assets in any such sale or disposition or the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) assumes all the obligations of that Guarantor under its Subsidiary Guarantee pursuant to a supplemental indenture satisfactory to the Trustee; or

(B) an amount equal to the Net Proceeds of such sale or other disposition is applied in accordance with Section 4.7 hereof.

(b) The Subsidiary Guarantee of a Guarantor shall be automatically and unconditionally released:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation), other than to the Company or another Guarantor, if the Company applies the Net Proceeds of that sale or other disposition in accordance with Section 4.7 hereof;

(2) in connection with any sale or other disposition of all of the Capital Stock of a Guarantor (including by way of merger or consolidation) other than to the Company or another Guarantor, if the Company applies the Net Proceeds of that sale or other disposition in accordance with Section 4.7 hereof;

(4) if the Company exercises either its legal defeasance option or its covenant defeasance option in accordance with Section 8.1(b) hereof.

(c) Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that any of the conditions described in clauses (1) – (4) of Section 10.9(b) has occurred, the Trustee shall execute any supplemental indenture or other documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee and this Indenture.

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

1. Interest. Petrohawk Energy Corporation, a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Security at 7.875% per annum from May 13, 2008 until maturity. The Company will pay interest semi-annually in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Security is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be December 1, 2008. The Company will pay, to the extent lawful, interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, at the rate then in effect; it will pay, to the extent lawful, interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate as on overdue principal. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. The Company will pay interest on the Securities (except Defaulted Interest) to the Persons who are registered Holders of Securities at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such Securities are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.11 of the Indenture with respect to Defaulted Interest. The Securities will be payable as to principal, premium, if any, and interest at the office or agency of the Paying Agent maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed by such Paying Agent to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, and premium, if any, on all Global Securities and all other Securities, the Holders of which hold at least $5,000,000 aggregate principal amount of the Securities and have provided wire transfer instructions to the Company and the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Holders must surrender their Securities to the Paying Agent to collect payments of principal and premium, if any.

A-2

3. Paying Agent and Registrar. Initially, U.S. Bank Trust National Association will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent or Registrar without notice to any Holder, and the Company or any of its Subsidiaries may act as Paying Agent or Registrar, all in accordance with the Indenture.

4. Indenture. The Company issued the Securities under an Indenture, dated as of May 13, 2008 (the “Indenture”), among the Company, the Guarantors named on the signature pages thereto and U.S. Bank Trust National Association, as 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. The Securities are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling (to the extent permitted by law). The Securities are unsecured obligations of the Company. The Company initially has issued $500,000,000 aggregate principal amount of Securities. The Company may issue Additional Securities under the Indenture, subject to Section 4.3 of the Indenture; provided, however, that no Additional Securities may be issued at a price that would cause such Additional Securities to have “original issue discount” within the meaning of Section 1273 of the Code; and provided, further, that in no event may the Company issue any Additional Securities if, as a result of any such issuance, the aggregate principal amount of Securities outstanding would exceed the maximum aggregate principal amount of Securities permitted under the Existing Credit Facilities or any other Credit Facility, in each case as in effect on the date of such issuance.

5. Redemption.


Year	Redemption Price
2010	103.938	%
2011	101.969	%
