The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The terms and provisions contained in the Notes will 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 Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

Notwithstanding anything else herein, with respect to any Additional Notes issued subsequent to the date of this Indenture, when the context requires all provisions of this Indenture shall be construed and interpreted to permit the issuance of such Additional Notes and to allow such Additional Notes to become fungible and interchangeable with the Initial Notes originally issued under this Indenture. Indebtedness represented by Additional Notes shall be subject to the covenants contained in this Indenture.

Section 2.02 Execution and Authentication. At least one Officer must sign the Notes for the Company by manual, facsimile or electronically transmitted signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

A Note will not be valid until authenticated by the manual or electronic signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee will, upon receipt of a written order of the Company signed by an Officer of the Company (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

The Company will notify the

36

Trustee in writing of the name and address of any Agent not a party to this Indenture.

The Company or any of the Company’s Restricted Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

The Company initially appoints the Trustee to act as the Registrar and Paying Agent (at its office indicated in the definition of Corporate Trust Office of the Trustee in Section 1.01 hereof) and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust. The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, on, and interest, if any, on, the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Restricted Subsidiary) will have no further liability for the money. If the Company or a Restricted Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes.

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

(h)    General Provisions Relating to Transfers and Exchanges.

(i)    To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request.

46

(ii)    No service charge will be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note 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 payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

(iii)    All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits hereunder, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(iv)    Neither the Registrar nor the Company will be required:

(A)    to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

Section 2.07 Replacement Notes. If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

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

Section 2.08 Outstanding Notes. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a

47

Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a Restricted Subsidiary or an Affiliate of any thereof) holds, by 10:00 a.m. Eastern Time on a redemption date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee actually knows are so owned will be so disregarded.

Section 2.10 Temporary Notes. Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest. If the Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than ten days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

48

Section 2.13 CUSIP Numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

ARTICLE 3 REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee. If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least five Business Days prior to the giving of notice of a redemption, an Officers’ Certificate setting forth:

Section 3.02 Selection of Notes to Be Redeemed. If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2 hereof, by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law) unless otherwise required by law or applicable stock exchange or depositary requirements. Notwithstanding the foregoing, no Notes of $2,000 or less can be redeemed in part.

In the event of partial redemption by lot, the particular Notes to be redeemed will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

The Trustee will promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03 Notice of Redemption. At least 30 days but not more than 60 days before a redemption date, the Company will mail or cause to be mailed, by first class mail, or send electronically if DTC is the recipient, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or 11 hereof.

The notice will identify the Notes to be redeemed and will state:

(a)    the redemption date;

(b)    the redemption price (if then determined and otherwise the method of determination);

(c)    if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancellation of the original Note;

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

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

(f)    that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

(g)    the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(h)    that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; and

(i)    if applicable, any condition to such redemption.

At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Officers’ Certificate delivered to the Trustee pursuant to Section 3.01 hereof requests that the Trustee give such notice and sets forth the information to be stated in such notice as provided in the preceding paragraph.

Any such redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including completion of an Equity Offering or other corporate transaction or event. If such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied or waived (provided that in no event shall such redemption date be delayed to a date later than 60 days after the date on which such notice was sent), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed. If any such condition precedent has not been satisfied, the Company shall provide notice to the Trustee prior to the close of business on the Business Day prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded and the redemption of the Notes shall not occur. Upon receipt, the Trustee shall provide such notice to each Holder in the same manner in which the notice of redemption was given if such notice was given by the Trustee.

Section 3.04 Effect of Notice of Redemption. Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable (subject to the provisions of Section 3.03 hereof) on the redemption date at the redemption price.

Section 3.05 Deposit of Redemption or Purchase Price. No later than 10:00 a.m. Eastern Time on the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of, and accrued interest, if any, on, all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest, if any, on, all Notes to be redeemed or purchased.

50

If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or tendered for purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, including any Applicable Premium or Redemption Price Premium, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part. Upon surrender of a Note, that is not a Global Note, that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for, and deliver to, the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. For Notes issued in Global Form, the Trustee will reflect the amount of any increase or decrease as appropriate to reflect the amount outstanding at the request of the Company.

(e)    The Company may redeem all (but not a portion of) the Notes when permitted by, and pursuant to the conditions in, Section 4.15(e) hereof.

(f)    Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Section 3.08 Mandatory Redemption. The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

Section 3.09 Offer to Purchase by Application of Excess Proceeds or Unapplied Proceeds. In the event that, pursuant to Sections 4.10 or 4.18 hereof, the Company is required to commence an Asset Sale Offer or Repurchase Offer, as applicable, to all Holders to purchase Notes, it will follow the procedures specified below.

The Asset Sale Offer or Repurchase Offer, as applicable, shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets, casualty events or unpermitted debt issuances; provided, that an Asset Sale Offer or Repurchase Offer may be conditioned upon the application of proceeds as otherwise permitted by Sections 4.10 and 4.18 hereof. The Asset Sale Offer or Repurchase Offer, as applicable, will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds or Unapplied Proceeds, as applicable, (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer or Repurchase Offer, as applicable; provided that the Purchase Date shall occur not more than 365 days after receipt by the Company of the proceeds of sales of assets (or such longer period as permitted in Section 4.10 hereof), casualty events or unpermitted debt issuances, as applicable. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

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

Upon the commencement of an Asset Sale Offer or Repurchase Offer, as applicable, the Company will send, by first class mail, or send electronically if DTC is the recipient, a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes

52

pursuant to the Asset Sale Offer or Repurchase Offer, as applicable. The notice, which will govern the terms of the Asset Sale Offer or Repurchase Offer, as applicable, will state:

(a)    that the Asset Sale Offer or Repurchase Offer, as applicable, is being made pursuant to this Section 3.09 and Sections 4.10 or 4.18 hereof, as applicable, and the length of time the Asset Sale Offer or Repurchase Offer, as applicable, will remain open;

(b)    the Offer Amount, the purchase price and the Purchase Date;

(c)    that any Note not tendered or accepted for payment will continue to accrue interest;

(d)    that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer or Repurchase Offer, as applicable, will cease to accrue interest on and after the Purchase Date;

(e)    that Holders electing to have a Note purchased pursuant to an Asset Sale Offer or Repurchase Offer, as applicable, may elect to have Notes purchased in denominations of $2,000 or an integral multiple of $1,000 in excess thereof;

(f)    that Holders electing to have Notes purchased pursuant to any Asset Sale Offer or Repurchase Offer, as applicable, will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

(g)    that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, electronic image scan, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(h)    that, if the aggregate principal amount of Notes surrendered by Holders thereof exceeds the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer or Repurchase Offer, as applicable, the Trustee will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis (except that any Notes represented by a Global Note shall be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law) based on the principal amount of Notes surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and

(i)    that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof tendered pursuant to the Asset Sale Offer or Repurchase Offer, as applicable, and required to be purchased pursuant to this Section 3.09 and Sections 4.10 and 4.18 hereof, as applicable, or if Notes in an aggregate principal amount less than the Offer Amount allocated to the purchase of Notes in the Asset Sale Offer or Repurchase Offer, as applicable, have been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms

53

of this Section 3.09. The Company, the depositary for the Asset Sale Offer or Repurchase Offer, as applicable, or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the City and State of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(d)    For so long as any Notes remain outstanding, the Company will furnish to the Holders and Beneficial Owners of the Notes and to the securities analysts, broker dealers and prospective investors, upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act.

(e)    If at any time the Company is no longer required pursuant to any Credit Facility to deliver a Reserve Report with respect to the Company’s and its Restricted Subsidiaries’ Proved Reserves, the Company shall, upon request of any Holder, on April 1 and October 1 of each year furnish or make available to the Trustee and each Holder (a) a Reserve Report evaluating, as of the immediately preceding January 1 and July 1, as applicable, of each year with respect to such Proved Reserves, which Reserve Report, in the case of each January 1 report shall be prepared or audited by the Company’s independent reserve engineers and in the case of each other Reserve Report shall be prepared internally by the Company; (b) an Officers’ Certificate certifying that in all material respects: (i) such Reserve Report has been prepared in accordance with the procedures used to prepare the Reserve Report delivered pursuant to the Credit Agreement; (ii) the information contained in the Reserve Report and any other information delivered in connection therewith is true and correct in all material respects; and (iii) none of the Company’s and its Restricted Subsidiaries’ Proved Reserves included in such Reserve Report have been transferred, assigned or otherwise disposed of since the date of such Reserve Report except for those Oil and Gas Properties described in such certificate as having been disposed of.

(ii)    make loans or advances to the Company or any of its Restricted Subsidiaries (it being understood that the subordination of loans or advances made to the Company or any of its Restricted Subsidiaries to other Indebtedness incurred by the Company or any of its Restricted Subsidiaries shall not be deemed a restriction on the ability to make loans or advances); or

(iii)    sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

61

(ii)    the Note Documents;

(iii)    agreements governing other Indebtedness permitted to be incurred under Section 4.09 hereof and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the encumbrances or restrictions contained therein are not, in the reasonable good faith judgment of an Officer of the Company, materially more restrictive, taken as a whole, than those contained in the Note Documents or the Credit Agreement as in effect on the Issue Date;

(iv)    applicable law, rule, regulation or order;

(v)    any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings thereof; provided that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith judgment of an Officer of the Company, no more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(vi)    customary non-assignment provisions in Hydrocarbon purchase and sale or exchange agreements or similar operational agreements or in licenses, easements or leases, in each case, entered into in the ordinary course of business;

(viii)    any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending its sale or other disposition;

(ix)    Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are, in the reasonable good faith judgment of an Officer of the Company, not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

62

(x)    Liens permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;

(xi)    provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements (including agreements entered into in connection with a Restricted Investment) entered into with the approval of the Company’s Board of Directors, which limitation is applicable only to the assets that are the subject of such agreements;

(xii)    encumbrances or restrictions applicable only to a Restricted Subsidiary that is not a Domestic Subsidiary;

(xiii)    encumbrances or restrictions on cash or other deposits or net worth imposed by customers or lessors under contracts or leases entered into in the ordinary course of business; and

(a)    The Company will not, and will not permit any of its Restricted Subsidiaries to, 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), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any Preferred Stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and the Guarantors may incur Indebtedness (including Acquired Debt) or issue Preferred Stock, 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 or such Disqualified Stock or such Preferred Stock is issued, as the case may be, would have been at least 2.5 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the Preferred Stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b)    Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness or issuances of Disqualified Stock or Preferred Stock, as applicable (collectively, “Permitted Debt”):

(i)    the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness and letters of credit under the Credit Agreement and any Additional RBL Facility in an aggregate principal amount at any one time outstanding under this clause (i) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and the Guarantors thereunder) not to exceed $2.5 billion;

(ii)    Existing Indebtedness (other than clause (i) above);

(iii)    the incurrence by the Company or any of its Restricted Subsidiaries of Parity Lien Debt in an aggregate principal amount at any one time outstanding under this clause (iii) not to exceed $400.0 million (which such amount shall include the Notes); provided, that, (A) for the twelve-month period following the Issue Date, any additional Parity Lien Debt may only be incurred pursuant to an issuance of Additional Notes to the Original Investor in exchange for 2023 Notes or 2024 Notes at the rate that has been agreed with the Original Investor, and (B) after the twelve-month period following the Issue

63

Date, the Original Investor shall have a right of first refusal with respect to $50 million of any amount of capacity to incur Indebtedness remaining under this clause (iii);

(iv)    the incurrence by the Company or any of its Restricted Subsidiaries of Parity Lien Debt in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness of the Company or any of its Restricted Subsidiaries in an aggregate principal amount not to exceed $300 million; provided, that (A) the final maturity of such additional Parity Lien Debt shall be equal to or later than the final maturity of the Notes, and (B) such additional Parity Lien Debt shall have covenants and events of default that are not materially more restrictive, taken as a whole, than those applicable to the Notes;

(v)    the incurrence by the Company or any of its Restricted Subsidiaries of Junior Lien Debt in an aggregate principal amount not to exceed the greater of (i) $400.0 million and (ii) 10.0% of the Company’s Adjusted Consolidated Net Tangible Assets, provided that either (a) such Junior Lien Debt has a final maturity date or redemption date, as applicable, that is more than 91 days after the final maturity of the Notes, or (b) upon incurrence of such Junior Lien Debt, the Stated Maturity of the Notes shall be deemed to be automatically amended such that it occurs at least 91 days prior to the final maturity date or redemption date of the Junior Lien Debt;

(vi)    the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (vi), not to exceed the greater of (a) $50.0 million and (b) 2.5% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence;

(vii)    the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) of the Company or any of its Restricted Subsidiaries or any Disqualified Stock of the Company, in each case that was incurred under Section 4.09(a) hereof or clauses (ii), (iii), (iv), (v), (vi) or (xvii) of this Section 4.09(b); provided, that if such Indebtedness incurred under this clause (vii) Refinances Junior Lien Debt or unsecured Indebtedness that was incurred under Section 4.09(a) hereof or clauses (ii), (v) or (xvii) of this Section 4.09(b), such Indebtedness (x) shall have covenants and events of default, taken as a whole, not materially more restrictive than those applicable to the Notes and (y) after giving effect to the issuance of such Indebtedness, either (A) the Company would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof or (B) the Company’s interest expense for the most recently ended four quarter period on a pro forma basis for the incurrence shall not have increased;

(viii)    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)    if the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be unsecured and

64

expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the Note Guarantee, in the case of a Guarantor; and

(B)    (1) 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 of the Company and (2) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary of the Company,

will 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 (viii);

(ix)    the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any Preferred Stock; provided, however, that:

(A)    any subsequent issuance or transfer of Equity Interests that results in any such Preferred Stock being held by a Person other than the Company or a Restricted Subsidiary of the Company; and

(B)    any sale or other transfer of any such Preferred Stock to a Person that is not either the Company or a Restricted Subsidiary of the Company, will be deemed, in each case, to constitute an issuance of such Preferred Stock by such Restricted Subsidiary that was not permitted by this clause (ix);

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

(xi)    the Guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company to the extent that the Guaranteed Indebtedness was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes, then the Guarantee must be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed;

(xii)    the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, performance, bid, plugging and abandonment, appeal, reimbursement, performance, surety and similar bonds, and completion guarantees provided by the Company or a Restricted Subsidiary of the Company in the ordinary course of business and any Guarantees or letters of credit functioning as or supporting any of the foregoing bonds or obligations and workers’ compensation claims in the ordinary course of business;

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

(xiv)    the incurrence by the Company or any of its Restricted Subsidiaries of in-kind obligations relating to net oil or natural gas balancing positions arising in the ordinary course of business;

(xv)    any obligation arising from agreements of the Company or any Restricted Subsidiary of the Company providing for indemnification, adjustment of purchase price, earn-outs, or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of

65

any business, assets or Capital Stock of a Restricted Subsidiary in a transaction permitted by this Indenture; provided that such obligation is not reflected as a liability on the face of the balance sheet of the Company or any Restricted Subsidiary;

(xvi)    any Permitted Acquisition Indebtedness; and

(xvii)    the incurrence by the Company or any of its Restricted Subsidiaries of additional unsecured Indebtedness or the issuance by the Company of any Disqualified Stock in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any unsecured Indebtedness incurred or Disqualified Stock issued pursuant to this clause (xvii), not to exceed, at any one time outstanding, the greater of (a) $100.0 million and (b) 5.0% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance.

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

For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xvii) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Company will be permitted to divide, classify and reclassify such item of Indebtedness on the date of its incurrence, or later redivide or reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under the Credit Agreement outstanding on the date on which Notes are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (i) of the definition of Permitted Debt and may not be reclassified.

The accrual of interest or Preferred Stock or Disqualified Stock dividends or distributions, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness secured by a Junior Lien or not secured by a Lien in the form of additional Indebtedness with the same terms, the reclassification of Preferred Stock or Disqualified Stock as Indebtedness due to a change in accounting principles, and the payment of dividends or distributions on Preferred Stock or Disqualified Stock in the form of additional shares or units of the same class of Preferred Stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Preferred Stock or Disqualified Stock for purposes of this Section 4.09; provided that, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term.

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

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

(B)    the principal amount of the Indebtedness, in the case of any other Indebtedness; and

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

66

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

(2)    the amount of the Indebtedness of the other Person.

Section 4.10 Asset Sales. The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(a)    the Company or any of its Restricted Subsidiaries, as the case may be, receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or Equity Interests issued or sold or otherwise disposed of; and

(b)    at least 75% of the aggregate consideration received in the Asset Sale by the Company or such Restricted Subsidiary and all other Asset Sales since the Issue Date is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will, on a cumulative basis, be deemed to be cash:

(i)    any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any of its Restricted Subsidiaries (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee, including Junior Lien Debt and unsecured Indebtedness) that are assumed by the transferee of any such assets pursuant to a novation or indemnity agreement that releases the Company or such Restricted Subsidiary from or indemnifies the Company or such Restricted Subsidiary against any and all further liability;

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

(iii)    any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are, within 180 days of the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(iv)    any Capital Stock or assets of the kind referred to in clause (ii) or (iv) of Section 4.10(c) hereof; and

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

(c)    Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or one or more of its Restricted Subsidiaries may apply an amount equal to the amount of such Net Proceeds at its option to any combination of the following:

(i)    to repay, repurchase or redeem any Priority Lien Obligations;

67

(ii)    to acquire all or substantially all of the assets, or any Capital Stock, of one or more other Persons primarily engaged in the Oil and Gas Business if, after giving effect to any such acquisition of Capital Stock, such Person becomes a Restricted Subsidiary of the Company;

(iii)    to make capital expenditures in respect of the Company’s or any of its Restricted Subsidiaries’ Oil and Gas Business; or

(iv)    to acquire other assets that are not classified as current assets under GAAP and that are used or useful in the Oil and Gas Business.

The 365-day period may be extended by 90 days with respect to the requirement of clause (ii) or (iv) of Section 4.10(c) hereof and the application of Net Proceeds with respect thereto if a bona fide binding contract committing to make the acquisition referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Company within 270 days after the receipt of any Net Proceeds from an Asset Sale; provided, however, that if such contract is terminated for any reason (i) prior to the end of the 365-day period, then such initial 365-day period shall not be extended and (ii) during such 90 day extension period, then such extension period shall end immediately and the Company or any of its Restricted Subsidiaries shall immediately use such Net Proceeds to repay, repurchase or redeem Priority Lien Obligations or make an Asset Sale Offer.

Pending the final application of any Net Proceeds in accordance with the requirements of clauses (i) through (iv) above, the Company or any of its Restricted Subsidiaries may temporarily invest the Net Proceeds in any manner that is not prohibited by this Indenture.

The Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(c) hereof will constitute “Excess Proceeds.” Subject to Section 3.09, when the aggregate amount of Excess Proceeds exceeds $50.0 million (on a rolling 12 month basis), the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section 4.10 with respect to offers to purchase, prepay or redeem such Indebtedness with the proceeds of sales of assets, to purchase, prepay or redeem, on a pro rata basis, the maximum principal amount of Notes and such other pari passu Indebtedness (plus all accrued interest on the Notes and other Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds; provided, that such Asset Sale Offer may be conditioned upon the application of proceeds as otherwise permitted by this Section 4.10. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds allocated to the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law), based on the amounts tendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with

68

each repurchase of Notes pursuant to a Change of Control Offer or an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with Section 3.09, Section 4.15 or this Section 4.10 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 or Section 4.15 hereof or this Section 4.10 by virtue of such compliance.

Section 4.11 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 of the Company (each, an “Affiliate Transaction”), unless:

(i)    the 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 in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the reasonable good faith judgment of the Board of Directors of the Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and

(ii)    the Company delivers to the Trustee:

(A)    with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11; and

(B)    with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $40.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 4.11 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of the Company, if any.

(b)    The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a) hereof:

(i)    any employment or consulting agreement, employee benefit plan, officer or director indemnification, compensation or severance agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and reasonable payments pursuant thereto;

(ii)    transactions between or among the Company or its Restricted Subsidiaries;

(iii)    transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(iv)    payment of reasonable and customary fees and reimbursements of expenses (pursuant to indemnity arrangements or otherwise) of officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries;

69

(v)    any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company;

(vi)    Restricted Payments that do not violate the provisions of Section 4.07 hereof and any Permitted Investment;

(vii)    [Reserved];

(ix)    loans or advances to or reimbursements of expenses incurred by employees for moving, entertainment and travel expenses and similar expenditures in the ordinary course of business;

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

(xi)    in the case of contracts for exploring for, producing, marketing, storing or otherwise handling Hydrocarbons, or activities or services reasonably related or ancillary thereto, or other operational contracts (including any participation drilling arrangements), any such contracts entered into in the ordinary course of business and otherwise in compliance with the terms of this Indenture (a) which are fair to the Company and its Restricted Subsidiaries, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party, in either case in the reasonable good faith determination of the Board of Directors of the Company or the senior management thereof, and (b) with respect to which the Company has complied with Section 4.11(a)(ii)(A) and 4.11(a)(ii)(B) hereof to the extent applicable; and

(xii)    any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of Section 4.11(a)(i) hereof.

Section 4.12 Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or assume any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets now owned or hereafter acquired.

Section 4.13 Business Activities. The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole.

70

(a)    its corporate existence and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary; and

(b)    the rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the senior management of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a)    Upon the occurrence of a Change of Control, except as provided in this Section 4.15, the Company will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of Control, the Company will send a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(i)    that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

(ii)    the purchase price and the expiration date of the Change of Control Offer, which shall be no earlier than 30 days and no later than 60 days from the date such notice is sent;

(iii)    that any Note not tendered will continue to accrue interest;

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

(v)    that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(vi)    that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, electronic image scan, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

(vii)    that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

71

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes 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 this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

(b)    Promptly following the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer. Promptly after such acceptance, the Company will, on the Change of Control Payment Date:

(i)    deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(ii)    deliver or cause to be delivered to the Trustee the Notes accepted for payment, together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

The Paying Agent will promptly mail (but in any case not later than five days after the Change of Control Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, it will make such payment through the facilities of DTC), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Company will announce publicly the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c)    Notwithstanding anything to the contrary in this Section 4.15, the Company will not be required to make a Change of Control Offer upon a Change of Control if (i) 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 Section 4.15 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (ii) notice of redemption of all outstanding Notes has been given pursuant to Section 3.03 hereof, unless and until there is a default in payment of the applicable redemption price or (iii) in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer.

(d)    Notwithstanding anything to the contrary contained herein, a Change of Control Offer or Alternate Offer may be made in advance of a Change of Control, conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer or Alternate Offer is made. The closing date of any Change of Control Offer made in advance of a Change of Control may be changed to conform to the actual closing date of the Change of Control; provided that such closing date is not earlier than 30 days nor later than 60 days from the date the Change of Control Offer notice is sent pursuant to Section 4.15(a) hereof.

(e)    In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer or Alternate Offer and the Company (or a third party making the Change of Control Offer or Alternate Offer in lieu of the Company as described in paragraph (c) above) purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer or Alternate Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment, plus, to the extent not included in the

72

Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain outstanding, to, but excluding, the date of redemption (subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

Section 4.16 Additional Note Guarantees. If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary after the Issue Date that incurs or guarantees Indebtedness under any Credit Facility, that Subsidiary will become a Guarantor by executing a supplemental indenture in substantially the form of Exhibit E hereto and delivering an Opinion of Counsel to the Trustee substantially contemporaneously with, but in any event no later than 30 days after, the acquisition or creation of that Subsidiary.

Section 4.17 Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be either (1) an Investment made as of the time of the designation that will reduce the amount available for Restricted Payments under Section 4.07(a) hereof or (2) a Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a Board Resolution giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, the Company will be in default of such covenant.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period and (2) no Default or Event of Default would be in existence following such designation.

Section 4.18 Casualty Events and Unpermitted Debt Issuances. Within 365 days after the receipt of any net cash proceeds arising in connection with (i) casualty events in an aggregate amount in excess of $25.0 million (“Casualty Events”), and (ii) debt issuances that are not permitted by Section 4.09 hereof (“Unpermitted Debt Issuances”), the Company or one or more of its Restricted Subsidiaries may apply an amount up to the aggregate amount of such net cash proceeds at its option to any combination of the following:

(i)    to repay, repurchase or redeem any Priority Lien Obligations;

(ii)    to acquire all or substantially all of the assets, or any Capital Stock, of one or more other Persons primarily engaged in the Oil and Gas Business if, after giving effect to any such acquisition of Capital Stock, such Person becomes a Restricted Subsidiary of the Company;

(iii)    to make capital expenditures in respect of the Company’s or any of its Restricted Subsidiaries’ Oil and Gas Business; or

73

(iv)    to acquire other assets that are not classified as current assets under GAAP and that are used or useful in the Oil and Gas Business.

The 365-day period may be extended by 90 days with respect to the requirement of clause (ii) or (iv) of this Section 4.18 hereof and the application of net cash proceeds with respect thereto if a bona fide binding contract committing to make the acquisition referred to therein is entered into by the Company or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Company within 270 days after the receipt of any net cash proceeds from Casualty Events or Unpermitted Debt Issuances; provided, however, that if such contract is terminated for any reason (i) prior to the end of the 365-day period, then such initial 365-day period shall not be extended and (ii) during such 90 day extension period, then such extension period shall end immediately and the Company or any of its Restricted Subsidiaries shall immediately use such Net Proceeds to repay, repurchase or redeem Priority Lien Obligations or make a Repurchase Offer.

Pending the final application of any such net cash proceeds in accordance with the requirements of clauses (i) through (iv) above, the Company or any of its Restricted Subsidiaries may temporarily invest such proceeds in any manner that is not prohibited by this Indenture.

The net cash proceeds from Casualty Events or Unpermitted Debt Issuances that are not applied or invested as provided in the first paragraph of this Section 4.18 will constitute “Unapplied Proceeds.” To the extent that any Unapplied Proceeds remain on the date falling 320 days after the receipt of net cash proceeds arising from a Casualty Event or an Unpermitted Debt Issuance, and subject to Section 3.09, the Company will make an offer (a “Repurchase Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section 4.18 with respect to offers to purchase, prepay or redeem such Indebtedness with the proceeds of casualty events or unpermitted debt issuances, on a pro rata basis, the maximum principal amount of Notes and such other pari passu Indebtedness (plus all accrued interest on the Notes and other Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Unapplied Proceeds. The offer price in any Repurchase Offer will be equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date, and will be payable in cash. If any Unapplied Proceeds remain after consummation of a Repurchase Offer, the Company or any of its Restricted Subsidiaries may use those Unapplied Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes tendered in such Repurchase Offer exceeds the amount of Unapplied Proceeds allocated to the purchase of Notes, the Trustee will select the Notes to be purchased on a pro rata basis (except that any Notes represented by a Note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximates pro rata selection as the Trustee deems fair and appropriate unless otherwise required by law), based on the amounts tendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in minimum denominations of $2,000, or an integral multiple of $1,000 in excess thereof, will be purchased).

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to this provision. To the extent that the provisions of any securities laws or regulations conflict with this provision, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of such compliance.

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

(ii)    results in the acceleration of such Indebtedness prior to its Stated Maturity,

76

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 $35.0 million or more; provided, however, that if, prior to any acceleration of the Notes, (i) any such Payment Default is cured or waived or (ii) any such acceleration is rescinded, any Default or Event of Default (but not any acceleration of the Notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment, decree or applicable law;

(g)    failure by the Company or any of its Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $35.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed, for a period of 30 days;

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

(ii)    appoints a custodian of the Company or any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; or

and the order or decree remains unstayed and in effect for 60 consecutive days;

(j)    except as permitted by this Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; and

(k)    the occurrence of any of the following:

77

(i)    except as permitted by the Note Documents, any Note Document establishing the Parity Liens ceases for any reason to be enforceable; provided that it will not be an Event of Default under this clause (k)(i) if the sole result of the failure of one or more Note Documents to be fully enforceable is that any Parity Lien purported to be granted under such Note Documents on Collateral, individually or in the aggregate, having a Fair Market Value of not more than $25.0 million, ceases to be an enforceable and perfected Parity Lien; provided, further, that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 30 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period;

(ii)    except as permitted by the Note Documents, any Parity Lien purported to be granted under any Note Document on Collateral, individually or in the aggregate, having a Fair Market Value in excess of $25.0 million, ceases to be an enforceable and perfected Parity Lien, subject to the Intercreditor Agreement and Permitted Liens; provided that if such failure is susceptible to cure, no Event of Default shall arise with respect thereto until 30 days after any officer of the Company or any Restricted Subsidiary becomes aware of such failure, which failure has not been cured during such time period; or

(iii)    the Company or any Guarantor, shall assert, in writing, that any security interest in any Security Document is invalid or unenforceable.

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

Without limiting the generality of the foregoing, it is understood and agreed that if the Notes are accelerated or otherwise become due prior to their stated maturity, in each case, as a result of an Event of Default (including, but not limited to, an Event of Default specified in clause 6.01(i) above (including the acceleration of any portion of the Indebtedness evidenced by the Notes by operation of law)), the Applicable Premium or the amount by which the applicable redemption price exceeds the principal amount of the Notes (the “Redemption Price Premium”), as applicable, with respect to an optional redemption of the Notes shall also be, without declaration or other act on the part of the Trustee or Holders, automatically and immediately due and payable as though the Notes had been optionally redeemed on the date of such acceleration and shall constitute part of the Obligations payable by the Company (and guaranteed by the Guarantors) with respect to the Notes, which Obligations are secured by the Collateral, and constitute liquidated damages, not unmatured interest or a penalty, in view of the impracticability and difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable estimate and calculation of each Holder’s actual lost profits and other actual damages of such Holders as a result thereof. If the Applicable Premium or the Redemption Price Premium, as applicable, becomes due and payable, it shall be deemed to be principal of the Notes and interest shall accrue on the full principal amount of the Notes (including the Applicable Premium or the Redemption Price Premium, as applicable) from and after the applicable triggering event, including in connection with an Event of Default specified in clause 6.01(i) above. Such premium shall also be automatically and immediately due and payable in the event the Notes or the Indenture are satisfied, released or discharged through foreclosure, whether by judicial proceeding, deed in lieu of foreclosure or by any other means. THE COMPANY AND THE GUARANTORS WILL EXPRESSLY WAIVE (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION, ANY RESCISSION OF SUCH ACCELERATION OR THE COMMENCEMENT OF ANY BANKRUPTCY OR INSOLVENCY EVENT. The Company and the Guarantors expressly agree (to the fullest extent it and they may lawfully do so) that: (A) any such premium is reasonable and is the product of an arm’s length transaction between sophisticated business entities ably represented by counsel; (B) such premium shall be payable notwithstanding the then prevailing market rates at the time acceleration and payment occurs; (C) there has been a course of conduct between the Holders and the Company and the Guarantors giving specific consideration in this transaction for such agreement to pay the premium; and (D) the Company and the Guarantors shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The

78

Company and the Guarantors expressly acknowledge that its and their agreement to pay the premium to the Holders as herein described is a material inducement to the Holders to purchase the Notes.

Section 6.02 Acceleration. In the case of an Event of Default specified in Section 6.01(h) or 6.01(i) hereof, with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

Upon any such declaration, the Notes shall become due and payable immediately.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders of all the Notes, rescind an acceleration and its consequences hereunder if, among other things, (1) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, on, and interest, if any, on, the Notes that has become due solely by such declaration of such acceleration, have been cured or waived and (3) the Trustee has been paid all amounts then owing to the Trustee under Section 7.07 hereof. No such rescission shall affect any subsequent Default or impair any right consequent thereon.

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

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

Section 6.04 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium, if any, on, or interest, if any, on, the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration, as provided in Section 6.02. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority. Holders of a majority in aggregate principal amount of the then outstanding Notes may 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 or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

Section 6.06 Limitation on Suits. No Holder may pursue any remedy with respect to the Note Documents unless:

79

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

(b)    Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(c)    such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity reasonably satisfactory to the Trustee against any loss, liability or expense;

(d)    the Trustee does not comply with such request within 60 days after receipt of the request and the offer, or provision if requested, of security or indemnity; and

(e)    during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.

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 6.07 Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium, if any, on, and interest, if any, on, the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), 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 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium, if any, on, and interest, if any, remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest, if any, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such 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 to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

80

Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First: to the Trustee and Collateral Agent and the applicable agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and Collateral Agent and the costs and expenses of collection;

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

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

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

Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

ARTICLE 7 TRUSTEE

Section 7.01 Duties of Trustee.

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

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

(i)    the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that

(ii)    in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(i)    this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

81

(ii)    the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

(e)    No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder has furnished to the Trustee security and indemnity reasonably satisfactory to it against any loss, liability or expense.

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

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

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

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

(f)    The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders have furnished to the Trustee indemnity or security reasonably satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

(g)    The Trustee shall not be deemed to have notice of a Default or an Event of Default unless a Responsible Officer of the Trustee has received from the Company, any Guarantor, or any Holder written notice thereof at its address as set forth in Section 12.02, and such notice references the Notes and this Indenture.

82

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

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

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

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

(l)    The permissive right of the Trustee to take any action under this Indenture shall not be construed as a duty to so act.

Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest after a Default has occurred and is continuing it must eliminate such conflict within 90 days or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04 Trustee’s Disclaimer. The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Section 7.05 Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is actually known to the Trustee, the Trustee will send to Holders a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, on, or interest, if any, on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders.

Section 7.06 [Reserved.]

Section 7.07 Compensation and Indemnity.

(a)    The Company will pay to the Trustee and the Collateral Agent from time to time reasonable compensation for its acceptance of this Indenture and services hereunder as agreed in a separate fee agreement. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances

83

and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b)    The Company and the Guarantors will jointly and severally indemnify the Trustee and the Collateral Agent against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c)    The obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

(d)    To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium, if any, on, and interest, if any, on, particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture.

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

Section 7.08 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 7.08.

(b)    The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

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

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

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

(iv)    the Trustee becomes incapable of acting.

(c)    If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

84

(d)    If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(e)    If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f)    A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee.

Section 7.10 Eligibility; Disqualification.

There will 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 $100.0 million as set forth in its most recent published annual report of condition.

ARTICLE 8 LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall

85

execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(a)    the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, on, or interest, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(b)    the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

(c)    the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith; and

(d)    this Article 8.

Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their respective obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17 and 4.18 hereof and clause (iii) of Section 5.01(a) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes to the extent permitted by GAAP). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(c), (d), (e), (f), (g) and (j) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or Section 8.03 hereof:

(a)    the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants delivered to the Trustee, to pay the principal of, premium, if any, on, and interest, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be,

86

and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;

(b)    in the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(i)    the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

(ii)    since the Issue Date, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Beneficial Owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(c)    in the case of an election under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Beneficial Owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d)    no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(e)    such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(f)    the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and

(g)    the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

The Collateral will be released from the Lien securing the Notes, pursuant to Section 13.06, upon a Legal Defeasance or Covenant Defeasance in accordance with Article 8.

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the

87

Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, on, and interest, if any, on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest, if any, has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, on, or interest, if any, on, any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9 AMENDMENT, SUPPLEMENT AND WAIVER

(d)    to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under this Indenture of any Holder, including to comply with requirements of the SEC or DTC in order to maintain the transferability of the Notes pursuant to Rule 144A or Regulation S;

(e)    conform the text of the Note Documents or any other such documents (in recordable form) as may be necessary or advisable to preserve and confirm the relative priorities of the Priority Lien Documents and the Parity Lien Documents as such priorities are contemplated by and set forth in the Intercreditor Agreement or the Collateral Agency Agreement, as applicable;

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

Upon the request of the Company, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such

89

amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Company, the Guarantors and the Trustee may amend or supplement this Indenture (including Sections 3.09, 4.10, 4.15 and 4.18 hereof) and the other Note Documents with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, on, or interest, if any, on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of the Note Documents may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes) in each case in addition to any required consent of holders of other Parity Lien Obligations required with respect to any amendment or waiver under any other Note Document. Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. Notwithstanding anything to the contrary herein, however, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(b)    reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption or repurchase of the Notes (other than provisions relating to minimum required notice of optional redemption or provisions under Sections 3.09, 4.10, 4.15 or 4.18 hereof);

(c)    reduce the rate of or change the time for payment of interest on any Note;

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

(e)    make any Note payable in money other than that stated in the Notes;

(f)    make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, premium, if any, on, or interest, on, the Notes (other than as permitted in clause (g) below);

(g)    waive a redemption or repurchase payment with respect to any Note;

(h)    release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(i)    make any change in the preceding amendment, supplement or waiver provisions.

The consent of Holders representing at least two-thirds of the aggregate principal amount of outstanding Notes will be required to release the Liens for the benefit of the Holders of the Notes on all or substantially all of the Collateral, other than in accordance with the Note Documents.

90

Upon the request of the Company to the Trustee, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

It is not necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Section 9.03 [Reserved.]

Section 9.04 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

ARTICLE 10 NOTE GUARANTEES

Section 10.01 Guarantee.

(a)    Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally Guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee

91

and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(i)    the principal of, premium, if any, on, and interest, if any, on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, on, and interest, if any, on, the Notes, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(ii)    in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

Failing payment when due of any amount so Guaranteed or any performance so Guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a Guarantee of payment and not a Guarantee of collection.

(b)    The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c)    If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by any of them to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d)    Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations Guaranteed hereby until payment in full of all obligations Guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the obligations Guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations Guaranteed hereby, and (ii) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor and, by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note 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 Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be

92

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 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Officer or person holding an equivalent title.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Note Guarantee will be valid nevertheless.

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

In the event that the Company or any of its Restricted Subsidiaries creates or acquires any Domestic Subsidiary after the Issue Date, if required by Section 4.16 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.16 hereof and this Article 10, to the extent applicable.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05 hereof, a Guarantor may not: (A) consolidate or merge with or into another Person (whether or not such Guarantor is the surviving Person), or (B) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of such Guarantor, in one or more related transactions, to another Person, other than the Company or another Guarantor, unless:

(a)    immediately after giving effect to such transaction or series of transactions, no Default or Event of Default exists; and

(b)    either:

(i)    subject to Section 10.05 hereof, the Person acquiring the properties or assets in any such sale, assignment, transfer, conveyance or other disposition or the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) unconditionally assumes all the obligations of that Guarantor under the Note Documents pursuant to a supplemental indenture and joinder, in form reasonably satisfactory to the Trustee or Collateral Agent, as applicable; or

(ii)    the Net Proceeds of such transaction or series of transactions are applied in a manner that does not violate Section 4.10 hereof.

In case of any such consolidation, merger, sale or other disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee of the Guarantor and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, (x) such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor and (y) such Note

93

Guarantee will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though such Note Guarantee had been issued at the date of the execution hereof.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 10.04(b)(i) and (ii) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or other disposition of the properties or assets of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05 Releases.

The Note Guarantee of a Guarantor shall be automatically released:

(a)    in connection with any sale or other disposition of all or substantially all of the properties or assets of that Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.10 hereof;

(b)    in connection with any sale or other disposition of Capital Stock of that Guarantor by way of merger, consolidation or otherwise to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.10 hereof and such Guarantor ceases to be a Restricted Subsidiary of the Company as a result of the sale or other disposition;

(c)    upon designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture;

(d)    upon the liquidation or dissolution of such Guarantor in a transaction or series of transactions that does not violate the terms of the Note Documents; or

(e)    upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of, premium, if any, on, and interest, if any, on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

ARTICLE 11 SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

This Indenture will be satisfied and discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified in this Article 11), when:

(a)    either:

(i)    all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

94

(ii)    all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the giving of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and interest, if any, to the date of Stated Maturity or redemption;

(b)    in respect of subclause (ii) of clause (a) of this Section 11.01, no Event of Default has occurred and is continuing on the date of the deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to secure such borrowings);

(c)    the Company or any Guarantor has paid or caused to be paid all other sums payable by it under this Indenture; and

In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, and interest, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has made any payment of principal of,

95

premium, if any, on, and interest, if any, on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

The Trustee, the Collateral Agent and each Holder of Notes, by accepting the Notes and the Guarantees of the Guarantors, acknowledges that, as more fully set forth in the Security Documents, the Collateral as now or hereafter constituted shall be held for the benefit of all the holders of Parity Lien Obligations, subject to the Intercreditor Agreement, the Collateral Agent and the Trustee, and the Lien of this Indenture and the Security Documents is subject to and qualified and limited in all respects by the Intercreditor Agreement, the Security Documents and actions that may be taken thereunder.

Section 13.02 Collateral Requirements.

(a)    The Security Documents and Mortgages providing for the Parity Liens shall be substantially in the form of the corresponding instruments providing for the Priority Liens, with only such changes as are reasonably necessary to reflect the terms of the Intercreditor Agreement and with such deletions or modifications of representations, warranties and covenants as are customary with respect to security documents establishing Liens securing debt securities sold in similar private transactions that are not subject to registration requirements of the Securities Act.

(b)    Except as otherwise provided in the Intercreditor Agreement and subject to Section 13.02(d) below, the Collateral securing the Notes and the obligations of Guarantors under the Note Guarantees and all other Parity Lien Obligations will consist of all Property securing any other Secured Debt including substantially all of the Company’s and the Guarantors’ Oil and Gas Properties constituting Proved Reserves, and substantially all other property of the Company and the Guarantors, including all deposit accounts and securities accounts, in each case, other than Excluded Assets.

100

(c)    In addition, the Collateral will not include any Priority Lien Collateral that is or may be provided as cash collateral to certain issuers of letters of credit pursuant to the Priority Lien Documents rather than generally to the holders of Priority Lien Obligations or to the Priority Lien Collateral Agent for the benefit of the holders of the Priority Lien Obligations as a whole. The creation or perfection of pledges of or security interests in particular assets will not be required if, and for so long as, the creation or perfection of such security interests would require a foreign law governed security or pledge agreement.

(d)    Notwithstanding the foregoing, the Company will provide a valid and perfected Parity Lien securing the Parity Lien Obligations on Oil and Gas Properties that include not less than 90% of the total value of Proved Reserves attributable to the Oil and Gas Properties of the Company and its Restricted Subsidiaries (the “Collateral Coverage Minimum”). Compliance shall only be measured at the time of delivery of each such Reserve Report and as of each June 30th and December 31st and shall be evaluated with respect to Proved Reserves, based on the Reserve Report most recently delivered under the Credit Agreement or as otherwise required by Section 4.03, in each case after giving effect to acquisitions, dispositions, extensions, discoveries and upward and downward revisions of estimates of Proved Reserves due to exploration, development or exploitation, production or other activities or changes in geological conditions or other factors, as applicable, which, in each case, would, in accordance with standard industry practice, cause such revisions since the date of such Reserve Report or financial statements, as applicable; provided that the Company and the Guarantors shall be deemed to be in compliance with this coverage requirement as long as the Company has executed and delivered, or shall have caused the applicable Guarantor to execute and deliver, to the Collateral Agent, as mortgagee or beneficiary, as applicable, such Mortgages and supplements or amendments related thereto, together with evidence (which may include confirmation from the title insurance company insuring the lien) of the completion (or arrangements for the completion) of all recordings and filings of such Mortgages or other supplements or amendments in the proper recorders’ offices or appropriate public records (and payment of any taxes or fees in connection therewith) within the later to occur of (i) 45 days after such testing date and (ii) the date that the Company shall have been required to provide additional Mortgages to the Credit Agreement Agent under the Credit Agreement. It is agreed and understood that the only obligation the Company shall have under this Agreement or the Note Documents with respect to providing a valid and perfected Parity Lien with respect to real property shall be to deliver Mortgages to the Collateral Agent (i) with respect to Oil and Gas Properties sufficient to meet the Collateral Coverage Minimum and (ii) with respect to any real property subject to a Priority Lien securing the Credit Agreement. No building or manufactured (mobile) home (as defined in the applicable flood insurance regulations) shall be included in the definition of “Collateral” or subject to a lien under this Agreement or the Note Documents. The Company will deliver to the Trustee semi-annually on or before March 1 and September 1 in each calendar year, beginning March 1, 2021, an Officer’s Certificate certifying that, as of the date of such certificate, such requirement has been satisfied.

(e)    The Company will, or will cause the applicable Guarantor to, execute and deliver to the Collateral Agent, as mortgagee or beneficiary, as applicable, such Mortgages or other Security Documents, and any supplements or amendments related thereto, together with evidence (which may include confirmation from the title insurance company insuring the lien) of the completion (or arrangements for the completion) of all recordings and filings of such Mortgages or other Security Documents in the proper recorders’ offices or appropriate public records (and payment of any taxes or fees in connection therewith) as may be necessary to create a valid, perfected second-priority Lien (subject to the Intercreditor Agreement and to Permitted Prior Liens), on or against the Collateral within 30 days after the Issue Date. In addition and without limitation of Section 13.03(d) below, the Security Documents will not require that security interests be perfected if such security interest are not perfected with respect to any Priority Lien Obligations and such security interests cannot be perfected by the filing of UCC financing statements, the recording of mortgages or deeds of trust or the execution of control agreements with respect to certain deposit accounts, securities accounts and commodities accounts; provided, the Company shall have used its commercially reasonable efforts for a period of at least 90 days to enter into control agreements in favor of the Collateral Agent in respect to deposit accounts, securities accounts and commodities accounts, the Company and the Guarantors shall be relieved of any further obligation to deliver control agreements so long as the Priority Lien

101

Representative or agents or bailees of the Priority Lien Representative maintains a perfected second-priority lien (subject to the Intercreditor Agreement) for the benefit of the holders of Notes and any future other Parity Lien Obligations through control of such deposit accounts, securities accounts and commodities accounts pursuant to a control agreement.

Section 13.03 Further Assurances; After Acquired Collateral.

(a)    The Company and each of the Guarantors shall do or cause to be done all acts and things that may be reasonably required, or that the Collateral Agent (acting at the direction of the Parity Lien Representatives) may from time to time reasonably request, to assure and confirm that the Collateral Agent holds, for the benefit of the holders of the Parity Lien Obligations, duly created and enforceable and perfected Liens upon the Collateral (including any property or assets constituting Collateral that are acquired or otherwise become, or are required by any Parity Lien Document to become, Collateral after the Issue Date), in each case, as contemplated by, and with the Lien priority required under, the Parity Lien Documents and in connection with any merger, consolidation or sale of assets of the Company or any Guarantor, the property and assets of the Person which is consolidated or merged with or into the Company or any Guarantor, to the extent that they are property or assets of the types which would constitute Collateral under the Security Documents, shall be treated as after-acquired property and the Company or such Guarantor shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Parity Liens, in the manner and to the extent required under the Security Documents.

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

(c)    In addition, from and after the Issue Date, if the Company or any Guarantor acquires any property or asset that constitutes Collateral which requires any supplemental Security Document for such Collateral or other actions to achieve a perfected Lien on such Collateral, then the Company shall, or shall cause the applicable Guarantor to, promptly (but in any event no later than the date that is 45 days after which such Collateral is acquired) execute and deliver to the Collateral Agent appropriate Security Documents (or amendments thereto) in such form as shall be necessary to grant the Collateral Agent a perfected second-priority Lien on such Collateral or take such other actions in favor of the Collateral Agent as shall be reasonably necessary to grant a perfected Lien on such collateral to the Collateral Agent, subject to the terms of this Indenture, the Intercreditor Agreement and the other Note Documents; provided, that, the Company and the Guarantors will be deemed to have complied with this Section 13.03 with respect to any Oil and Gas Properties constituting Collateral if the Company has complied with Section 13.02(d) and (e). Additionally, subject to this Indenture, the Intercreditor Agreement and the other Note Documents, if the Company or any Guarantor creates any additional Lien upon any property or asset that would constitute Collateral, or takes any additional actions to perfect any existing Lien on Collateral, in each case for the benefit of the holders of the Priority Lien Debt or the holders of Junior Lien Debt, after the Issue Date, the Company or such Guarantor, as applicable, must, to the extent permitted by applicable law, within 20 Business Days after such Lien is granted or other action taken, grant a second-priority Lien (subject to the terms of this Indenture, the Intercreditor Agreement and the other Note Documents) upon such property or asset, or take such additional perfection actions, as applicable, for the benefit of the holders and obtain all related deliverables as those delivered

102

to the Priority Lien Representative or Junior Lien Collateral Agent, as applicable, in each case as security for the obligations of the Company with respect to the Notes, the obligations of the Guarantors under the Note Guarantees and the performance of all other obligations of the Company and the Guarantors under the Note Documents.

(d)    Notwithstanding the foregoing, to the extent that any Lien on any Collateral is perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the Priority Lien Representative, or of agents or bailees of the Priority Lien Representative, the perfection actions and related deliverables described in this Section 13.03 shall not be required.

Section 13.04 Intercreditor Agreement.

This Article 13 and the provisions of each other Security Document are subject to the terms, conditions and benefits set forth in the Intercreditor Agreement. The Company and each Guarantor consents to, and agrees to be bound by, the terms of the Intercreditor Agreement, as the same may be in effect from time to time, and to perform its obligations thereunder in accordance with the terms thereof.
