     The terms of the Notes are governed by the Indenture, dated as of May 25, 2011 (the “Indenture”), by and among Range, the Subsidiary Guarantors and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of May 25, 2011 (the “Supplemental Indenture”). The Notes will mature on June 1, 2021. Interest will accrue from May 25, 2011, and the first interest payment date will be December 1, 2011. Range may redeem some or all of the Notes at any time on or after June 1, 2016 at the redemption prices specified in the Supplemental Indenture. Range may also redeem up to 35% of the Notes using all or a portion of the net proceeds of certain public sales of equity interests completed before June 1, 2014. Range may also redeem the Notes prior to June 1, 2016 upon payment of the make-whole premium specified in the Supplemental Indenture. If Range sells certain of its assets or upon the occurrence of certain changes in control, Range must offer to repurchase the Notes. The Notes are unsecured, and are subordinated to all of Range’s existing and future senior debt, rank equally with all of Range’s existing and future senior subordinated debt and rank senior to all of Range’s existing and future subordinated debt.

ARTICLE 1
Definitions and Incorporation by Reference

     Section 1.01 Definitions.

     “Acquired Debt” means, with respect to any specified Person, (i) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Subsidiary of such specified Person, including, without limitation, Indebtedness incurred in connection with, or in contemplation of, such other Person merging with or into or becoming a Subsidiary of such specified Person, and (ii) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person.

     “Additional Securities” means any Securities issued under the Indenture in addition to the Initial Securities in accordance with Section 2.03. Additional Securities will be treated as part of the same series of Securities as the Initial Securities for all purposes under this Indenture.

     “Adjusted Consolidated Net Tangible Assets” means (without duplication), as of the date of determination, (i) the sum of (a) discounted future net revenues from proved oil and gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with the Commission’s guidelines before any state or federal income taxes, with no less than 80% of the discounted future net revenues estimated by one or more nationally recognized firms of independent petroleum engineers in a reserve report prepared as of the end of the Company’s most recently completed fiscal year, as increased by, as of the date of determination, the estimated discounted future net revenues from (1) estimated proved oil and gas reserves acquired since the date of such year-end reserve report, and (2) estimated oil and gas reserves attributable to upward revisions of estimates of proved oil and gas reserves since the date of such year-end reserve report due to exploration, development or exploitation activities, in each case calculated in accordance with the Commission’s guidelines (utilizing the prices utilized in such year-end reserve report) increased by the accretion of the discount from the date of the reserve report to the date of determination, and decreased by, as of the date of determination, the estimated discounted future net revenues from (3) estimated proved oil and gas reserves produced or disposed of since the date of such year-end reserve report and (4) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since the date of such year-end reserve report due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated in accordance with the Commission’s guidelines (utilizing the prices utilized in such year-end reserve report); provided, that, in the case of each of the determinations made pursuant to clause (1) through (4), such increases and decreases shall be as estimated by the Company’s petroleum engineers, unless in the event that there is a Material Change as a result of such acquisitions, dispositions or revisions, then the discounted future net revenues utilized for purposes of this clause (i) (a) shall be confirmed in writing by one or more nationally recognized firms of independent petroleum engineers, (b) the capitalized costs that are attributable to oil and gas properties of the Company and its Restricted Subsidiaries to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest annual or quarterly financial statements, (c) the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial statements and (d) the greater of (1) the net book value on a date no earlier than the date of the Company’s latest annual or quarterly financial statements or (2) the book value of other tangible assets (including, without duplication, investments in unconsolidated Restricted Subsidiaries and mineral rights held under lease or other contractual arrangements) of the Company and its Restricted Subsidiaries, as of the date no earlier than the date of the Company’s latest annual or quarterly financial statements, minus (ii) the sum of (a) minority interests, (b) any gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest audited financial statements, and (c) the

discounted future net revenues, calculated in accordance with the Commission’s guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in clause (i)(a) above, would be necessary to fully satisfy the payment obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto. If the Company changes its method of accounting from the successful efforts method to the full cost method or a similar method of accounting, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if the Company was still using the successful efforts method of accounting.

For purposes of this definition, “control” (including, with correlative meanings, the terms “controlling,” “controlled by” and “under common control with”), as used with respect to any Person, shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise; provided, that beneficial ownership of 10% or more of the voting securities of a Person shall be deemed to be control.

     “Agent” means any Registrar, Paying Agent or Authenticating Agent.

All Securities need not be issued at the same time and, unless otherwise provided, Additional Securities may be issued, subject to any limitations herein; provided, however, that any such issuance made under the same CUSIP number as the original issuance will be made only if such Additional Securities are fungible with the original issuance for U.S. federal income tax purposes.

     If any of the terms of the Securities of any series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth, or providing the manner for determining, the terms of the Securities, and an appropriate record of any action taken pursuant thereto in connection with the issuance of any Securities of such series shall be delivered to the Trustee prior to the authentication and delivery thereof.

The Company may act as Registrar or (except for purposes of Article 8) Paying Agent. In each case the Company and the Trustee will enter into an appropriate agreement with the Agent implementing the provisions of the Indenture relating to the obligations of the Trustee to be performed by the Agent and the related rights. The Company initially appoints the Trustee as Registrar and Paying Agent.

     (b) 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 the Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or of interest on the Securities and will promptly notify the Trustee of any Default by the Company in making any such payment. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed, and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require the Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon doing so, the Paying Agent will have no further liability for the money so paid over to the Trustee.

     Section 2.06 Replacement Securities. If a mutilated Security is surrendered to the Trustee or if a Holder claims that its Security has been lost, destroyed or wrongfully taken, the Company will issue and the Trustee will authenticate a replacement Security of like tenor and principal amount and bearing a number not contemporaneously outstanding. Every replacement Security is an additional Obligation of the Company and entitled to the benefits of the Indenture. If required by the Trustee or the Company, an indemnity must be furnished that is sufficient in the judgment of both the Trustee and the Company to protect the Company and the Trustee from any loss they may suffer if a Security is replaced. The Company may charge the Holder for the expenses of the Company and the Trustee in replacing a Security. In case the mutilated, lost, destroyed or wrongfully taken Security has become or is about to become due and payable, the Company in its discretion may pay the Security instead of issuing a replacement Security.

     (a) Securities outstanding at any time are all Securities that have been authenticated by the Trustee except for

          (1) Securities cancelled by the Trustee or delivered to it for cancellation;

          (2) any Security which has been replaced pursuant to Section 2.06 unless and until the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser; and

          (3) on or after the maturity date or any redemption date or date for repurchase of the Securities pursuant to an Asset Sale Offer or a Change of Control Offer, those Securities payable or to be redeemed or

repurchased on that date for which the Trustee (or Paying Agent, other than the Company or an Affiliate of the Company) holds money sufficient to pay all amounts then due.

     (b) A Security does not cease to be outstanding because the Company or one of its Affiliates holds the Security, provided, that in determining whether the Holders of the requisite principal amount of the outstanding Securities have given or taken any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, Securities owned by the Company or any Affiliate of the Company will be disregarded and deemed not to be outstanding, (it being understood that in determining whether the Trustee is protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other action, only Securities which the Trustee actually knows to be so owned will be so disregarded). Securities so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any Affiliate of the Company.

     Section 2.08 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee will authenticate temporary Securities. Temporary Securities will be substantially in the form of definitive Securities but may have insertions, substitutions, omissions and other variations determined to be appropriate by the Company Officer executing the temporary Securities, as evidenced by the execution of the temporary Securities. If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities will be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for the purpose pursuant to Section 4.02, without charge to the Holder. Upon surrender for cancellation of any temporary Securities the Company will execute and the Trustee will authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged, the temporary Securities will be entitled to the same benefits under the Indenture as definitive Securities.

     Section 2.09 Cancellation. The Company at any time may deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold. Any Registrar or the Paying Agent will forward to the Trustee any Securities surrendered to it for transfer, exchange or payment. The Trustee will cancel all Securities surrendered for transfer, exchange, payment or cancellation and dispose of them in accordance with its document retention procedures or the written instructions of the Company. The Company may not issue new Securities to replace Securities it has paid in full or delivered to the Trustee for cancellation.

     Section 2.10 CUSIP and CINS Numbers. The Company in issuing the Securities may use “CUSIP” and “CINS” numbers, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption or exchange or in offers to purchase as a convenience to Holders, the notice to state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption or exchange. The Company will promptly notify the Trustee in writing of any change in the CUSIP or CINS numbers.

     Section 2.11 Registration, Transfer and Exchange.

     (a) The Securities will be issued in registered form only, without coupons, and the Company shall cause the Registrar to maintain a register (the “Register”) of the Securities, for registering the record ownership of the Securities by the Holders and transfers and exchanges of the Securities.

     (b) (1) Each Global Security will be registered in the name of the Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend set forth in Exhibit A.

          (2) Each Global Security will be delivered to the Trustee as custodian for the Depositary. Transfers of a Global Security (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except (x) as set forth in Section 2.11(b)(4) and (y) transfers of portions thereof in the form of Certificated Securities may be made upon request of an Agent Member (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.11.

          (3) Agent Members will have no rights under the Indenture with respect to any Global Security held on their behalf by the Depositary, and the Depositary shall be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Security through an Agent Member) to take any action which a Holder is entitled to take under the Indenture or the Securities, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

          (4) If (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for a Global Security and a successor depositary is not appointed by the Company within 90 days of the notice or (y) an Event of Default has occurred and is continuing and the Trustee has received a request from the Depositary, the Trustee will promptly exchange each beneficial interest in the Global Security for one or more Certificated Securities in authorized denominations having an equal aggregate principal amount registered in the name of the owner of such beneficial interest, as identified to the Trustee by the Depositary, and thereupon the Global Security will be deemed canceled. Each Certificated Security will be registered in the name of the Holder thereof or its nominee.

     (c) A Holder may transfer a Security to another Person or exchange a Security for another Security or Securities of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange. The Registrar will promptly register any transfer or exchange that meets the requirements of this Section by noting the same in the Register maintained by the Registrar for the purpose; provided, that

          (x) no transfer or exchange will be effective until it is registered in such Register and

          (y) the Trustee will not be required (i) to issue, register the transfer of or exchange any Security for a period of 15 days before a selection of Securities to be redeemed or repurchased, (ii) to register the transfer of or exchange any Security so selected for redemption or repurchase in whole or in part, except, in the case of a partial redemption or repurchase, that portion of any Security not being redeemed or repurchased, or (iii) if a redemption or a repurchase is to occur after a regular record date but on or before the corresponding related interest payment date, to register the transfer of or exchange any Security on or after the regular record date and before the date of redemption or repurchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will treat the Person in whose name the Security is registered as the owner and Holder thereof for all purposes (whether or not the Security is overdue), and will not be affected by notice to the contrary.

     From time to time the Company will execute and the Trustee will authenticate additional Securities as necessary in order to permit the registration of a transfer or exchange in accordance with this Section.

     No service charge will be imposed in connection with any transfer or exchange of any Security, 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 a transfer tax or other similar governmental charge payable upon exchange pursuant to subsection (b)(4)).

     (d) (1) Global Security to Global Security. If a beneficial interest in a Global Security is transferred or exchanged for a beneficial interest in another Global Security, the Trustee will (x) record a decrease in the principal amount of the Global Security being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global Security. Any beneficial interest in one Global Security that is transferred to a Person who takes delivery in the form of a beneficial interest in another Global Security, or exchanged for a beneficial interest in another Global Security, will, upon transfer or exchange, cease to be an owner of a beneficial interest in such Global Security and become an owner of a beneficial interest in the other Global Security and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

          (2) Global Security to Certificated Security. If a beneficial interest in a Global Security is transferred or exchanged for a Certificated Security, the Trustee will (x) record a decrease in the principal amount of such

Global Security equal to the principal amount of such transfer or exchange and (y) deliver one or more new Certificated Securities in authorized denominations having an equal aggregate principal amount to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name of such transferee or owner, as applicable.

          (3) Certificated Security to Global Security. If a Certificated Security is transferred or exchanged for a beneficial interest in a Global Security, the Trustee will (x) cancel such Certificated Security, (y) record an increase in the principal amount of such Global Security equal to the principal amount of such transfer or exchange and (z) in the event that such transfer or exchange involves less than the entire principal amount of the canceled Certificated Security, deliver to the Holder thereof one or more new Certificated Securities in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Security, registered in the name of the Holder thereof.

          (4) Certificated Security to Certificated Security. If a Certificated Security is transferred or exchanged for another Certificated Security, the Trustee will (x) cancel the Certificated Security being transferred or exchanged, (y) deliver one or more new Certificated Securities in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Security (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Certificated Security, deliver to the Holder thereof one or more Certificated Securities in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Security, registered in the name of the Holder thereof.

     Section 2.12 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, it shall 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 Securities and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Security and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided, that no such special record date shall be less than 10 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) shall 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.

ARTICLE 3
Redemption and Prepayment

     Section 3.01 Notices to Trustee. The Securities may be redeemable at the option of the Company as provided in the terms of the Securities. If the Company elects to redeem Securities pursuant to the optional redemption provisions thereof, then it shall furnish to the Trustee, at least 45 days but not more than 60 days before a redemption date (or such shorter time as shall be agreed by the Trustee), an Officers’ Certificate setting forth (i) the paragraph of the Securities pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Securities to be redeemed and (iv) the redemption price.

     Section 3.02 Selection of Securities to be Redeemed. If less than all of the Securities are to be redeemed at any time, selection of Securities for redemption shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed as the Trustee is advised by the Company, or, if the Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided, that no Securities of $1,000 or less shall be redeemed in part. In the event of partial redemption by lot, the particular Securities to be redeemed shall 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 Securities not previously called for redemption.

     The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. Securities and portions of Securities selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Securities of a Holder are to be redeemed, the entire outstanding amount of Securities held by such Holder, even if

not a multiple of $1,000, shall be redeemed. A new Security in principal amount equal to the unredeemed portion thereof shall be issued in the name of the Holder thereof upon cancellation of the original Security. On and after the redemption date, unless the Company defaults in payment of the redemption price, interest ceases to accrue on Securities or portions of them called for redemption. Except as provided in this Section 3.02, provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.

     The provisions of the two preceding paragraphs of this Section 3.02 shall not apply with respect to any redemption affecting only a Global Security, whether such Global Security is to be redeemed in whole or in part. In case of any such redemption in part, the unredeemed portion of the principal amount of the Global Security shall be in an authorized denomination.

     Section 3.03 Notice of Redemption. Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder of Securities to be redeemed at such Holder’s registered address, provided, however, that the Company shall provide notice to the Trustee pursuant to Section 3.01 hereof at least three days (or such shorter period as shall be satisfactory to the Trustee) prior to the mailing of the notice pursuant to this Section 3.03.

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

     (a) the redemption date;

     (b) the redemption price;

     (c) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the redemption date upon surrender of such Security, a new Securities or Securities in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Security;

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

     (e) that Securities 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 Securities called for redemption cease to accrue on and after the redemption date;

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

     (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 Securities.

     If any of the Securities to be redeemed is in the form of a Global Security, then such notice shall be modified in form but not substance to the extent appropriate to accord with the procedures of the Depositary applicable to redemptions.

     At the Company’s request and expense, the Trustee shall give the notice of redemption in the Company’s name; provided, however, that the Company shall have delivered to the Trustee, at least 45 days (or such shorter period as shall be satisfactory to the Trustee) prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the second preceding paragraph.

     Section 3.04 Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03 hereof, Securities called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional.

     Section 3.05 Deposit of Redemption Price. On or prior to the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all

Securities to be redeemed on that date. The Trustee or the Paying Agent shall promptly return without interest 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 price of and accrued interest on all Securities to be redeemed.

     If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Securities or the portions of Securities called for redemption. If a Security is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Security was registered at the close of business on such record date. If any Security called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption 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 Securities and in Section 4.01 hereof.

     Section 3.06 Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall issue and, upon the receipt of a written authentication order of the Company signed by an Officer of the Company, the Trustee shall authenticate for the Holder at the expense of the Company a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

     Section 3.07 Optional Redemption. Any redemption contemplated by the terms of the Securities shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

     Section 3.08 Mandatory Redemption. Except as set forth under Sections 4.10 and 4.13 hereof, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities.

     Section 3.09 Offer to Purchase by Application of Excess Proceeds. In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence an offer to all Holders of Securities and, to the extent required by the terms thereof, to all holders or lenders of other pari passu Indebtedness, to repurchase Securities and any such pari passu Indebtedness (an “Asset Sale Offer”), it shall follow the procedures specified below.

     The Asset Sale Offer shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination of the Offer Period (the “Purchase Date”), the Company shall purchase the principal amount of Securities required to be purchased pursuant to Section 4.10 hereof, giving effect to any related offer for pari passu Indebtedness pursuant to Section 4.10, (the “Offer Amount”) or, if less than the Offer Amount has been tendered, all Securities tendered in response to the Asset Sale Offer. Payment for any Securities so purchased shall 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 shall be paid to the Person in whose name a Security is registered at the close of business on such record date, and no interest shall be payable to Holders who tender Securities pursuant to the Asset Sale Offer.

     Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders. The notice shall contain all instructions and materials necessary to enable such Holders to tender Securities pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state:

     (a) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain open;

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

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

     (d) that, unless the Company defaults in making such payment, any Security accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest after the Purchase Date;

     (e) that Holders electing to have a Security purchased pursuant to an Asset Sale Offer may only elect to have all of such Security purchased and may not elect to have only a portion of such Security purchased;

     (f) that Holders electing to have a Security purchased pursuant to any Asset Sale Offer shall be required to surrender the Security, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Security completed, or transfer by book-entry transfer, to the Company, the Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three Business Days before the Purchase Date;

     (g) that Holders shall 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, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Security purchased;

     (h) that, if the aggregate principal amount of Securities surrendered by Holders exceeds the Offer Amount, the Company shall select the Securities to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Securities in denominations of $1,000, or integral multiples thereof, shall be purchased) in the manner provided in Section 4.10; and

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

     If any of the Securities subject to an Asset Sale Offer is in the form of a Global Security, then such notice may be modified in form but not substance to the extent appropriate to accord with the procedures of the Depositary applicable to repurchases.

     On or before the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Securities or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Securities tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Securities or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, shall 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 Securities tendered by such Holder and accepted by the Company for purchase, and the Company shall promptly issue a new Security, and the Trustee, upon receipt of a written authentication order of the Company signed by two Officers of the Company shall authenticate and mail or deliver such new Security to such Holder, in a principal amount equal to any unpurchased portion of the Security surrendered. Any Security not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer on the Purchase Date.

     Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

     The Company shall pay interest (including post-petition interest in any proceeding under the Bankruptcy Code) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Securities to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under the Bankruptcy Code) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.

     Section 4.02 Maintenance of Office or Agency. The Company shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where principal, premium, if any, and interest on the Securities will be paid and where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

     The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency for such purposes. The Company shall 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.

     Section 4.03 Reports.

As of the date hereof, the Company’s fiscal year ends on December 31 of each calendar year. In the event the Company changes its fiscal year, it shall promptly notify the Trustee in writing of such change.

     (c) The Company shall, so long as any of the Securities are outstanding, deliver to the Trustee, within five Business Days of any Officer becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

     Section 4.06 Stay, Extension and Usury Laws. Each of the Company and the Subsidiary Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of the Company and the Subsidiary Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

     Section 4.07 Restricted Payments. The Company shall not and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make any other payment or distribution on account of the Company’s Equity Interests (including, without limitation, any payment to holders of the Company’s Equity Interests in connection with any merger or consolidation involving the Company) or to the direct or indirect holders of the Company’s Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company); (ii) purchase, redeem or otherwise acquire or retire for value any Equity Interests of the Company; (iii) make any principal payment on, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the Securities, except at final maturity; or (iv) make any Restricted Investment (all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment:

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

          (c) such Restricted Payment, together with the aggregate of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the date of this Indenture (excluding Restricted Payments permitted by clauses (2), (3), (5) and (6) of the next succeeding paragraph), is less than the sum of (i) the dollar amount calculated as of the date of this Indenture under Section 4.07(c) of that certain Indenture dated July 21, 2003 among the Company, the Subsidiary Guarantors and The Bank of New York Mellon Trust Company, N.A., as successor trustee to Bank One, National Association, plus (ii) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from the beginning of the first fiscal quarter commencing prior to the date of this Indenture to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus (iii) 100% of the aggregate net cash proceeds received by the Company from the issue and sale since the date of this Indenture of Equity Interests in the Company or of debt securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or convertible debt securities) sold to a Subsidiary of the Company and other than Disqualified Stock or debt securities that have been converted into Disqualified Stock), plus (iv) 100% of the amount of net cash proceeds received by the Company or a Restricted Subsidiary from the sale within 12 months of the related acquisition of any of the following that are acquired after the date of the Indenture in exchange for Equity Interests of the Company (other than Disqualified Stock and other than Capital Stock issued to a Subsidiary of the Company): (A) any property or assets (other than Indebtedness and Capital Stock); (B) the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or another Restricted Subsidiary; or (C) Capital Stock constituting a minority interest in any Person that at such time is a Restricted Subsidiary, plus (v) to the extent that any Restricted Investment that was made after the date of this Indenture is sold for cash or otherwise liquidated or repaid for cash, the lesser of (A) the net proceeds of such sale, liquidation or repayment and (B) the initial amount of such Restricted Investment.

     The foregoing provisions shall not prohibit (1) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of this Indenture; (2) the redemption, repurchase, retirement or other acquisition of any Equity Interests of the Company in exchange for, or out of the proceeds of, the substantially concurrent sale (other than to a Subsidiary of the Company) of other Equity Interests of the Company (other than any Disqualified Stock); provided, that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement or other acquisition shall be excluded from clause (c)(iii) or (c)(iv) of the preceding paragraph; (3) the defeasance, redemption or repurchase of Subordinated Indebtedness with the net cash proceeds from an incurrence of Permitted Refinancing Debt or the substantially concurrent sale (other than to a Subsidiary of the Company) of Equity Interests of the Company (other than Disqualified Stock); provided, that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement or other acquisition shall be excluded from clause (c)(iii) or (c)(iv) of the preceding paragraph; (4) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Subsidiary of the Company held by any of the Company’s (or any of its Subsidiaries’) employees pursuant to any equity subscription agreement or stock option agreement in effect as of the date of this Indenture; provided, that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $2.0 million in any twelve-month period; and provided further, that no Default or Event of Default shall have occurred and be continuing immediately after such transaction; (5) repurchases of Equity Interests deemed to occur upon exercise of stock options if such Equity Interests represent a portion of the exercise price of such options; and (6) cash payments made by the Company for the repurchase, redemption or other acquisition or retirement of the Company’s 6⅜% Senior Subordinated Notes due 2015, 7¹/2% Senior Subordinated Notes due 2016, 7¹/2% Senior Subordinated Notes due 2017, 7¹/4% Senior Subordinated Notes due 2018, 8% Senior Subordinated Notes due 2019 or 6³/4% Senior Subordinated Notes due 2020.

Not later than five days after the date of making any Restricted Payment, the Company shall deliver to the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 4.07 were computed.

     In computing Consolidated Net Income for purposes of this Section 4.07, (i) the Company shall use audited financial statements for the portion of the relevant period for which audited financial statements are available on the date of determination and unaudited financial statements and other current financial data based on the books and records of the Company for the remaining portion of such period and (ii) the Company shall be permitted to rely in good faith on the financial statements and other financial data derived from the books and records of the Company that are available on the date of determination.

     The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be a Restricted Investment or, if applicable, a Permitted Investment at the time of such designation and must comply with this Section 4.07. All such outstanding Investments shall be deemed to constitute Investments in an amount equal to the greater of the fair market value or the book value of such Investments at the time of such designation. Such designation shall only be permitted if such Restricted Payment would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

     Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to (i)(x) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (1) on its

Capital Stock or (2) with respect to any other interest or participation in, or measured by, its profits, or (y) pay any indebtedness owed by it to the Company or any of its Restricted Subsidiaries, (ii) make loans or advances to the Company or any of its Restricted Subsidiaries or (iii) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries, except for such encumbrances or restrictions existing under or by reason of (a) the Credit Agreement and the indentures governing the Company’s 6⅜% Senior Subordinated Notes due 2015, 7¹/2% Senior Subordinated Notes due 2016, 7¹/2% Senior Subordinated Notes due 2017, 7¹/4% Senior Subordinated Notes due 2018, 8% Senior Subordinated Notes due 2019 and 6³/4% Senior Subordinated Notes due 2020, each as in effect as of the date of this Indenture, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof or any other Credit Facility or indenture or other financing agreement or instrument, provided, that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements, refinancings or other Credit Facilities or indentures or other financing agreements or instruments are not materially more restrictive taken as a whole with respect to such dividend and other payment restrictions than those contained in the Credit Agreement and such indentures as in effect on the date of the Indenture, (b) this Indenture and the Securities, (c) applicable law, (d) 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, in the case of Indebtedness, to the extent such Indebtedness 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 and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired, provided, that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred, (e) by reason of customary non-assignment provisions in leases and customary provisions in other agreements that restrict assignment of such agreements or rights thereunder, entered into in the ordinary course of business and consistent with past practices, (f) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (iii) above on the property so acquired or (g) Permitted Refinancing Debt, provided, that the restrictions contained in the agreements governing such Permitted Refinancing Debt are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced.

     Section 4.09 Incurrence of Indebtedness and Issuance of Disqualified Stock. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt) and the Company shall not issue any Disqualified Stock and shall not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock if:

          (i) 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 is issued would have been at least 2.5 to 1, determined on a pro forma basis as set forth in the definition of Fixed Charge Coverage Ratio; and

          (ii) no Default or Event of Default shall have occurred and be continuing at the time such additional Indebtedness is incurred or such Disqualified Stock is issued or would occur as a consequence of the incurrence of the additional Indebtedness or the issuance of the Disqualified Stock.

     Notwithstanding the foregoing, this Indenture shall not prohibit any of the following (collectively, “Permitted Indebtedness”): (a) the Indebtedness evidenced by the Initial Securities; (b) the Indebtedness evidenced by the Company’s 6⅜% Senior Subordinated Notes due 2015, 7¹/2% Senior Subordinated Notes due 2016, 7¹/2% Senior Subordinated Notes due 2017, 7¹/4% Senior Subordinated Notes due 2018, 8% Senior Subordinated Notes due 2019 and 6³/4% Senior Subordinated Notes due 2020; (c) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness pursuant to Credit Facilities, so long as the aggregate principal amount of all Indebtedness incurred pursuant to this clause (c) and outstanding under all Credit Facilities does not, at any one time, exceed the greater of (1) $1.5 billion and (2) an amount equal to the sum of (x) $50 million plus (y) 30% of Adjusted Consolidated Net Tangible Assets determined after the incurrence of such Indebtedness (including the application of the proceeds therefrom), (d) the guarantee by any Subsidiary Guarantor of any Indebtedness that is permitted by this Indenture to be incurred by the Company; (e) all Indebtedness of the Company and its Restricted Subsidiaries in existence as of the date of this Indenture; (f) intercompany Indebtedness between or among the Company and any of its Wholly Owned Restricted Subsidiaries; provided, however, that (1) if the Company is the

obligor on such Indebtedness, such Indebtedness is expressly subordinate to the payment in full of all Obligations with respect to the Securities and (2)(A) 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 Wholly Owned Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Wholly Owned Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be; (g) Indebtedness in connection with one or more standby letters of credit, guarantees, performance bonds or other reimbursement obligations, in each case, issued in the ordinary course of business and not in connection with the borrowing of money or the obtaining of advances or credit (other than advances or credit on open account, includible in current liabilities, for goods and services in the ordinary course of business and on terms and conditions which are customary in the Oil and Gas Business, and other than the extension of credit represented by such letter of credit guarantee or performance bond itself), not to exceed in the aggregate at any given time 5.0% of Total Assets; (h) Indebtedness under Interest Rate Hedging Agreements entered into for the purpose of limiting interest rate risks, provided, that the obligations under such agreements are related to payment obligations on Indebtedness otherwise permitted by the terms of this covenant and that the aggregate notional principal amount of such agreements does not exceed 105% of the principal amount of the Indebtedness to which such agreements relate; (i) Indebtedness under Oil and Gas Hedging Contracts, provided, that such contracts were entered into in the ordinary course of business for the purpose of limiting risks that arise in the ordinary course of business of the Company and its Restricted Subsidiaries; (j) the incurrence by the Company of Indebtedness not otherwise permitted to be incurred pursuant to this paragraph, provided, that the aggregate principal amount (or accreted value, as applicable) of all Indebtedness incurred pursuant to this clause (j), together with all Permitted Refinancing Debt incurred pursuant to clause (k) of this paragraph in respect of Indebtedness previously incurred pursuant to this clause (j), does not exceed $10.0 million at any one time outstanding; (k) Permitted Refinancing Debt incurred in exchange for, or the net proceeds of which are used to refinance, extend, renew, replace, defease or refund, Indebtedness that was permitted by this Indenture to be incurred (including Indebtedness previously incurred pursuant to this clause (k) and Indebtedness referred to in clause (e) above); (l) accounts payable or other obligations of the Company or any Restricted Subsidiary to trade creditors created or assumed by the Company or such Restricted Subsidiary in the ordinary course of business in connection with the obtaining of goods or services; and (m) Indebtedness consisting of obligations in respect of purchase price adjustments, guarantees or indemnities in connection with the acquisition or disposition of assets.

     The Company shall not permit any of its Unrestricted Subsidiary to incur any Indebtedness other than Non-Recourse Debt; provided, however, if any such Indebtedness ceases to be Non-Recourse Debt, such event shall be deemed to constitute an incurrence of Indebtedness by the Company.

     For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness incurred pursuant to and in compliance with this Section 4.09: (A) Indebtedness permitted by this covenant need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such Indebtedness, (B) in the event that Indebtedness meets the criteria of more than one of the types of Indebtedness permitted by this covenant to be incurred, the Company, in its sole discretion, will classify such item of Indebtedness on the date of incurrence (or later reclassify such Indebtedness from or after the first date on which the Company or its Restricted Subsidiaries could have incurred such Indebtedness under one or more other of such provisions) and only be required to include the amount and type of such Indebtedness in one or more of such provisions as it determines; and (C) the amount of any Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

     Section 4.10 Asset Sales. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, engage in an Asset Sale unless (i) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by a resolution of the Board of Directors of the Company set forth in an Officer’s Certificate delivered to the Trustee, which determination shall be conclusive evidence of compliance with this provision) of the assets or Equity Interests issued or sold or otherwise disposed of and (ii) at least 85% of the consideration therefor received by the Company or such Restricted Subsidiary in such Asset Sale, plus all other Asset Sales since the date of this Indenture, on a cumulative basis, is in the form of cash or Cash Equivalents; provided, that the amount of any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet), of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Securities or

any guarantee thereof) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability shall be treated as cash for the foregoing purposes.

     Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company may apply such Net Proceeds, at its option: (a) to reduce Senior Debt, (b) to acquire controlling interests in another Oil and Gas Business, (c) to make capital expenditures in respect of the Company’s or its Restricted Subsidiaries’ Oil and Gas Business, (d) to purchase long-term assets that are used or useful in such Oil and Gas Business or (e) to repurchase any Securities. Pending the final application of any such Net Proceeds, the Company may temporarily reduce Senior Debt that is revolving debt or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied as provided in the first sentence of this paragraph shall (after the expiration of the periods specified in this paragraph) be deemed to constitute “Excess Proceeds.”

     When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall make an Asset Sale Offer to purchase the maximum principal amount of Securities and any other pari passu Indebtedness to which the Asset Sale Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to, in the case of the Securities, 100% of the principal amount thereof plus accrued and unpaid interest thereon to the date of purchase or, in the case of any other pari passu Indebtedness, 100% of the principal amount thereof (or with respect to discount pari passu Indebtedness, the accreted value thereof) on the date of purchase, in each case, in accordance with the procedures set forth in Section 3.09 hereof or the agreements governing pari passu Indebtedness, as applicable. To the extent that the aggregate principal amount (or accreted value, as the case may be) of the Securities and pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes. If the sum of (i) the aggregate principal amount of Securities surrendered by Holders thereof, and (ii) the aggregate principal amount or accreted value, as the case may be, of other pari passu Indebtedness surrendered by holders or lenders thereof, exceeds the amount of Excess Proceeds, the Trustee and the trustee or other lender representatives for the pari passu Indebtedness shall select the Securities and other pari passu Indebtedness to be purchased on a pro rata basis, based on the aggregate principal amount (or accreted value, as applicable) thereof surrendered in such Asset Sale Offer. Upon completion of such Asset Sale Offer, the Excess Proceeds shall be reset at zero.

     Section 4.11 Transactions with Affiliates. The Company shall not, and shall 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 contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any of its Affiliates (each of the foregoing, an “Affiliate Transaction”), unless (i) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Subsidiary with an unrelated Person and (ii) the Company delivers to the Trustee (a) with respect to an Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $1,000,000 but less than or equal to $10,000,000, an Officers’ Certificate to the Trustee certifying that such Affiliate Transaction complies with clause (i) above, (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10,000,000 but less than or equal to $25,000,000, a resolution of the Board of Directors set forth in an Officer’s Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with clause (i) above and that such Affiliate Transaction or series of related Affiliate Transactions has been approved in good faith by a majority of the members of the Board of Directors of the Company who are disinterested with respect to such Affiliate Transaction or series of related Affiliate Transactions (which resolution shall be conclusive evidence of compliance with this provision) and (c) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25,000,000, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with clause (i) above and that such Affiliate Transaction or series of related Affiliate Transactions has been approved in good faith by a resolution adopted by a majority of the members of the Board of Directors of the Company who are disinterested with respect to such Affiliate Transaction or series of related Affiliate Transactions and an opinion as to the fairness to the Company or such Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued by an accounting, appraisal, engineering or investment banking firm of national standing (which resolution and fairness opinion shall be conclusive evidence of compliance with this provision); provided, however, that the foregoing shall not apply to (1) transactions contemplated by any employment agreement or other

compensation plan or arrangement entered into by the Company or any of its Subsidiaries in the ordinary course of business, (2) transactions between or among the Company and/or its Restricted Subsidiaries, (3) Permitted Investments and Restricted Payments that are permitted by Section 4.07 hereof, (4) any indemnification payment made to any director, officer or employee of the Company or any Subsidiary pursuant to charter, bylaw, statutory or contractual provisions, and (5) transactions with entities that are Affiliates of the Company or a Restricted Subsidiary only because of the ownership by the Company or a Restricted Subsidiary of Equity Interests in such entity.

     Section 4.12 Liens. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien securing Indebtedness of any kind (other than Permitted Liens) upon any of its property or assets, now owned or hereafter acquired, unless all payments under the Securities are secured by such Lien prior to, or on an equal and ratable basis with, the Indebtedness so secured for so long as such Indebtedness is secured by such Lien.

     Section 4.13 Offer to Repurchase Upon Change of Control.

     (a) Upon the occurrence of a Change of Control, each Holder of the Securities shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s Securities pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount of the Securities plus accrued and unpaid interest if any, thereon to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, unless a notice of redemption has been given with respect to the Securities, the Company shall mail a notice to each Holder stating: (1) a description of the transaction or transactions that constitute the Change of Control; (2) that the Change of Control Offer is being made pursuant to this Section 4.13 and that all Securities tendered shall be accepted for payment; (3) the purchase price and the purchase date described below (the “Change of Control Payment Date”); (4) that any Security not tendered shall continue to accrue interest, if any; (5) that, unless the Company defaults in the payment of the Change of Control Payment, all Securities accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest, if any, after the Change of Control Payment Date; (6) that Holders electing to have any Securities purchased pursuant to a Change of Control Offer shall be required to surrender the Securities, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Securities completed, 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; (7) that Holders shall 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, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Securities delivered for purchase, and a statement that such Holder is withdrawing his election to have the Securities purchased; and (8) that Holders whose Securities are being purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. The Company and each Subsidiary Guarantor shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable to such party in connection with the repurchase of the Securities as a result of a Change of Control.

     (b) On a Business Day that is no earlier than 30 days nor later than 60 days from the date that the Company mails or causes to be mailed notice of the Change of Control to the Holders (the “Change of Control Payment Date”), the Company shall, to the extent lawful, (i) accept for payment all Securities or portions thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all the Securities or portions thereof so tendered and (iii) deliver or cause to be delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of such Securities or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of the Securities so tendered the Change of Control Payment for such Securities, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided, that each such new Security shall be in a principal amount of $1,000 or an integral multiple thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

     The Change of Control provisions described above shall be applicable whether or not any other provisions of this Indenture are applicable.

     The Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.13 and purchases all Securities (or portions thereof) validly tendered and not withdrawn under such Change of Control Offer.

     Section 4.14 Additional Subsidiary Guarantees. In the event that the Company or any of its Restricted Subsidiaries shall acquire or create a material Restricted Subsidiary after the date of this Indenture, such newly acquired or created Restricted Subsidiary shall be deemed to make the guarantee set forth in Section 11.01 and the Company shall cause such Subsidiary to evidence such guarantee in the manner set forth in Section 11.02; provided, that, in no event shall any non-U.S. Subsidiary of the Company be deemed to make such guarantee or be required to execute a Guarantee in accordance with Section 11.02. For purposes of the foregoing, a Restricted Subsidiary shall be deemed to be “material” if it would not be a minor subsidiary within the meaning of Rule 3-10(h) of Regulation S-X under the Exchange Act.

     Section 4.15 Corporate Existence. Subject to Article 5 hereof, the Company and each of the Restricted Subsidiaries shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of the 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 (ii) the rights (charter, partnership agreement and statutory), licenses and franchises of the Company and the Restricted Subsidiaries; provided, however, that the Company and the Restricted Subsidiaries shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of the Restricted Subsidiaries, if the Board of Directors of the relevant Person shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and the Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Securities.

     Section 4.16 No Senior Subordinated Debt. Notwithstanding the provisions of Section 4.09 hereof, (i) the Company shall not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Debt of the Company and senior in any respect in right of payment to the Securities and (ii) the Subsidiary Guarantors shall not directly or indirectly incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to Senior Debt of the Company and senior in any respect in right of payment to the Guarantees; provided, however, that the foregoing limitations shall not apply to distinctions between categories of Indebtedness that exist by reason of any Liens arising or created in respect of some but not all such Indebtedness.

     Section 4.17 Business Activities. The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any material respect in any business other than the Oil and Gas Business.

ARTICLE 5
Successors

     Section 5.01 Merger, Consolidation, or Sale of Substantially All Assets. The Company shall not consolidate or merge with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, and the Company may not permit any of its Restricted Subsidiaries to enter into any such transaction or series of transactions if such transaction or series of transactions would, in the aggregate, result in a sale, assignment, transfer, lease, conveyance, or other disposition of all or substantially all of the properties or assets of the Company to another Person, in either case unless (i) the Company is the surviving corporation or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made (the “Surviving Entity”) is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia; (ii) the Surviving Entity (if the Company is not the continuing obligor under this Indenture) assumes all the obligations of the Company under the Securities and this Indenture pursuant to a supplemental indenture in a form reasonably satisfactory to the Trustee; (iii) immediately before and after giving effect to such transaction or series of

transactions no Default or Event of Default exists; (iv) the Company or Surviving Entity (if the Company is not the continuing obligor under this Indenture) will, at the time of such transaction or series of transactions and after giving pro forma effect thereto as if such transaction or series of transactions had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the test set forth in the first paragraph of Section 4.09 hereof. Notwithstanding the foregoing clause (iv), any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Company, and any Wholly Owned Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to another Wholly Owned Restricted Subsidiary without complying with such clause (iv).

     Section 5.02 Successor Corporation Substituted. Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.01 hereof, the Surviving Entity shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the "Company” shall refer instead to the Surviving Entity and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Securities except in the case of a sale of all of the Company’s assets that meets the requirements of Section 5.01 hereof.

ARTICLE 6
Defaults and Remedies

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

          (1) the Company defaults in the payment of interest on the Securities when the same becomes due and payable and the Default continues for a period of 30 days, whether or not such payment is prohibited by the provisions of Article 10 hereof;

          (2) the Company defaults in the payment of the principal of or premium, if any, on the Securities, whether or not such payment is prohibited by the provisions of Article 10 hereof;

          (4) the Company fails to observe or perform any covenant, condition or agreement on the part of the Company to be observed or performed pursuant to Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16 and 4.17 hereof and the Default continues for the period and after the notice specified below;

          (5) the Company fails to comply with any of its other agreements or covenants in, or provisions of, the Securities or this Indenture and the Default continues for the period and after the notice specified below;

          (6) except as permitted herein, any Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or a Subsidiary Guarantor, or any Person acting on behalf of a Subsidiary Guarantor, shall deny or disaffirm such Subsidiary Guarantor’s obligation under its Guarantee;

          (7) a default occurs under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists or shall be created hereafter, which default (a) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”) or (b) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there is then existing a Payment Default or the maturity of which has been so accelerated, aggregates $10 million or more; provided, that if any such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such

acceleration, as the case may be, such Event of Default under this Indenture and any consequential acceleration of the Securities shall be automatically rescinded;

          (8) a final non-appealable judgment or order or final non-appealable judgments or orders are rendered against the Company or any Restricted Subsidiary that remain unpaid or discharged for a period of 60 days and that require the payment of money, either individually or in an aggregate amount, in excess of $10 million;

               (b) appoints a Custodian of the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, or for all or substantially all of the property of the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, or

               (c) orders the liquidation of the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, and in each case the order or decree remains unstayed and in effect for 60 consecutive days.

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

     A Default under clause (4) is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities notify the Company and the Trustee, of the Default and the Company does not cure the Default within 30 consecutive days after receipt of the notice. A Default under clause (5) is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities notify the Company and the Trustee, of the Default and the Company does not cure the Default within 60 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.”

     Section 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in clauses (9) and (10) of Section 6.01 hereof) relating to the Company or any Subsidiary Guarantor occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities by written notice to the Company and the Trustee, may declare the unpaid principal amount of and any accrued and unpaid interest on all the Securities to be due and payable immediately. If payment of the Securities is accelerated because of an Event of Default, the Company shall notify the holders of Designated Senior Debt of such acceleration. Upon such declaration the principal and interest shall be due and payable immediately; provided, however, that so long as any Designated Senior Debt or any commitment therefor is outstanding, any such notice or declaration shall not become effective until the earlier of (a) five Business Days after such notice is delivered to the representative for the Designated Senior Debt or (b) the acceleration of any Designated Senior Debt and thereafter, payments on the Securities pursuant to this Article 6 shall be made only to the extent permitted pursuant to Article 10 herein. Notwithstanding the foregoing, if any Event of Default specified in clause (9) or (10) of Section 6.01 hereof relating to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, such an amount shall ipso facto become and be immediately due and payable without any declaration or other act or notice on the part of the Trustee or any Holder.

     After a declaration of acceleration under this Indenture, but before a judgment or decree for payment of principal, premium, if any, and interest on the Securities due under this Article 6 has been obtained by the Trustee, Holders of a majority in principal amount of the then outstanding Securities by written notice to the Company and the Trustee may rescind an acceleration and its consequences if (i) the Company or any Subsidiary Guarantor has paid or deposited with the Trustee a sum sufficient to pay (a) all sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and (b) all overdue interest on the Securities, if any, (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (iii) all existing Events of Default (except nonpayment of principal, premium, if any, or interest that has become due solely because of the acceleration) have been cured or waived.

     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, premium, if any, and interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Security 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. Holders of not less than a majority in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may on behalf of the Holders of all of the Securities waive an 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 or interest on the Securities (including in connection with an offer to purchase) (provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Securities may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). 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 principal amount of the then outstanding Securities may direct the time, method and place of conducting any proceeding for exercising any remedy available to 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 Securities or that may involve the Trustee in personal liability it being understood that (subject to Section 7.01) the Trustee shall have no duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders.

     Section 6.06 Limitation on Suits. A Holder of a Security may pursue a remedy with respect to this Indenture or the Securities only if:

               (a) the Holder of a Security gives to the Trustee written notice of a continuing Event of Default;

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

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

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

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

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

     Section 6.07 Rights of Holders of Securities to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal, premium, if any, and interest on the Security, on or after the respective due dates expressed in the Security (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(1) or (2) 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 or any Subsidiary Guarantor for the whole amount of principal of, premium, if any, and interest remaining unpaid on the Securities and interest on overdue principal and, to the extent lawful, interest 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 of the Securities allowed in any judicial proceedings relative to the Company or any of the Subsidiary Guarantors (or any other obligor upon the Securities), 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 Securities 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 provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and may be a member of the creditors’ committee.

     Section 6.10 Priorities. If the Trustee collects any money pursuant to this Article, it shall, subject to the provisions of Article 10, pay out the money in the following order:

     First: to the Trustee, its agents and attorneys for amounts due under Sections 6.08 and 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

     Second: to Holders of Securities for amounts due and unpaid on the Securities for principal, premium, if any, and accrued interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any, and accrued interest, as the case may be, 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 of Securities pursuant to this Section 6.10.

     Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as 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 does not apply to a suit by the Trustee, a suit by a Holder of a Security pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Securities.

     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 the Subsidiary Guarantors shall, 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 Securities and the Guarantees thereof on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities, which shall 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 (a) and (b) below, and to have satisfied all its other obligations under such Securities and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Securities to receive payments in respect of the principal, of, premium, if any, and interest on such Securities when such payments are due from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, (b) the Company’s obligations with respect to such Securities under Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith and (d) this Article 8.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Subsidiary Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Sections 4.03, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16 and 4.17 hereof and in clause (iv) of Section 5.01 and the covenants contained in the Guarantees with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Securities shall thereafter be deemed not “outstanding” for the purposes of any compliance certificate, direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such 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 shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture, such Securities and such Guarantees shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) (but only with respect to the Company’s failure to observe or perform the covenants, conditions and agreements of the Company under clause (iv) of Section 5.01), 6.01(4), 6.01(6), 6.01(7) and 6.01(8) and 6.01(9) and 6.01(10) (but only with respect to Restricted Subsidiaries) hereof shall not constitute Events of Default.

          (e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

          (f) the Company shall 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 the Securities over the other creditors of the Company, or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

     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 or 8.08 hereof in respect of the outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities 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 Holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

     The Company and the Subsidiary Guarantors shall 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 or 8.08 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 Securities.

     Anything in this Article 8 to the contrary notwithstanding, the Trustee shall 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 or 8.08 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, or interest on any Security and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as a general creditor, 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, shall 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 shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company. Any money held by the Trustee pursuant to this Section 8.06 shall be held uninvested and without liability for interest.

     Section 8.07 Reinstatement. If the Trustee or Paying Agent is unable to apply any United States 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 obligations of the Company and the Subsidiary Guarantors under this Indenture, the Securities and the Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof, as the case may be; provided, however, that if the Company or any Subsidiary Guarantor makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Company or such Subsidiary Guarantor shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

     Section 8.08 Satisfaction and Discharge. The Indenture will be discharged and will cease to be of further effect as to all Securities issued thereunder, when: (1) either (a) all Securities that have been authenticated (except lost, stolen or destroyed Securities that have been replaced or paid and Securities for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company) have been delivered to the Trustee for cancellation, or (b) all Securities 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 (including pursuant to a notice of redemption duly given) within one year and the Company or any Subsidiary Guarantor has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust solely for the benefit of the Holders (in accordance with Section 8.05), 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 Securities not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; (2) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and such deposit will not result in a breach or violation of, or constitute a default under, any instrument (other than this Indenture) to which the Company or any Subsidiary Guarantor is a party or by which the Company or any Subsidiary Guarantor is bound; (3) the Company or any Subsidiary Guarantor has paid or caused to be paid all other sums payable by it under this Indenture; and (4) the Company has delivered an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

ARTICLE 9
Amendment, Supplement and Waiver

     Section 9.01 Without Consent of Holders of Securities. Notwithstanding Section 9.02 of this Indenture, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture, the Securities or the Guarantees without the consent of any Holder of a Security to establish the terms of the Securities in accordance herewith or:

          (a) to cure any ambiguity, defect or inconsistency;

          (b) to provide for uncertificated Securities in addition to or in place of Certificated Securities;

          (c) to provide for the assumption of the Company’s obligations to the Holders of the Securities in the case of a merger or consolidation pursuant to Article 5 hereof;

          (d) to make any change that would provide any additional rights or benefits to the Holders of the Securities or that does not adversely affect the legal rights hereunder of any Holder of a Security;

          (e) to secure the Securities or add guarantees thereof; or

          (f) to comply with requirements of the Commission in order to effect or maintain the qualification of this Indenture under the TIA.

     Upon the request of the Company accompanied by a resolution of the Board of Directors of the Company and each of the Subsidiary Guarantors, as the case may be, authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company and the Subsidiary 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 shall not be obligated to enter into such 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 Securities. Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture, the Securities and the Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for the Securities), 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, or interest on the Securities, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Securities or the Guarantees may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Securities (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for the Securities).

     Notwithstanding the foregoing, without the consent of at least 66⅔% in aggregate principal amount of the Securities then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for the Securities), no waiver or amendment to this Indenture may make any change in the provisions of Sections 3.09, 4.10 and 4.13 hereof that adversely affect the rights of any Holder of Securities. In addition, any amendment to the provisions of Article 10 of this Indenture shall require the consent of the Holders of at least 66⅔% in aggregate principal amount of the Securities then outstanding if such amendment would adversely affect the rights of Holders of Securities; provided, that, no amendment may be made to the provisions of Article 10 of this Indenture that adversely affects the rights of any holder of Senior Debt then outstanding unless the holders of such Senior Debt (or any group or representative thereof authorized to consent) consent to such change.

     Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company or any Subsidiary Guarantor with any provision of this Indenture, the Securities or the Guarantees. However, without the consent of each Holder affected, an amendment or waiver may not (with respect to any Securities held by a non-consenting Holder):

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

          (b) reduce the principal of or change the fixed maturity of any Security or alter the provisions with respect to the redemption of the Securities (except as provided above with respect to Sections 3.09, 4.10 and 4.13 hereof);

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

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

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

          (f) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Securities to receive payments of principal or premium, if any, or interest on the Securities; or

          (g) make any change in the foregoing amendment and waiver provisions.

     Upon the request of the Company accompanied by a resolution of the Board of Directors of the Company and each of the Subsidiary Guarantors, as the case may be, authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Securities as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company and the Subsidiary Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

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

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

     Section 9.03 Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Securities shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect.

     Section 9.04 Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder of a Security and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder of a Security or subsequent Holder of a Security may revoke the consent as to its Security if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

     The Company may, but shall not be obligated to, fix such record date as it may select for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

     Section 9.05 Notation on or Exchange of Securities. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Security thereafter authenticated. The Company in exchange for all Securities may issue and the Trustee shall authenticate new Securities that reflect the amendment, supplement or waiver.

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

     Section 9.06 Trustee to Sign Amendment, etc. The Trustee shall 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. Neither the Company nor any Subsidiary Guarantor may sign an amendment or supplemental Indenture until its respective Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01) shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that there has been compliance with all conditions precedent.

ARTICLE 10
Subordination

     Section 10.01 Agreement to Subordinate. The Company and each Subsidiary Guarantor agree, and each Holder by accepting a Security and the related Guarantees agrees, that (i) the Indebtedness evidenced by (a) the Securities, including, but not limited to, the payment of principal of, premium, if any, and interest on the Securities, and any other payment Obligation of the Company in respect of the Securities (including any obligation to repurchase the Securities) is subordinated in right of payment, to the extent and in the manner provided in this Article, to the prior payment in full in cash of all Senior Debt of the Company (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed), and (b) the Guarantees and other payment Obligations in respect of the Guarantees are subordinated in right of payment, to the extent and in the manner provided in this Article, to the prior payment in full in cash of all Senior Debt of each Subsidiary Guarantor and (ii) the subordination is for the benefit of the Holders of Senior Debt.

     Section 10.02 Certain Definitions.

     “Bankruptcy Law” means the Bankruptcy Code or any similar Federal or state law for the relief of debtors.

     “Representative” means the indenture trustee or other trustee, agent or representative for any Senior Debt.

     “Senior Debt” means (i) Indebtedness of the Company or any Subsidiary of the Company under or in respect of any Credit Facility, whether for principal, interest (including interest accruing after the filing of a petition initiating any proceeding pursuant to any Bankruptcy Law, whether or not the claim for such interest is allowed as a claim in such proceeding), reimbursement obligations, fees, commissions, expenses, indemnities or other amounts and (ii) any other Indebtedness of the Company or any Subsidiary of the Company permitted under the terms of this Indenture, unless the instrument under which such Indebtedness is incurred expressly provides that it is on a parity with or subordinated in right of payment to the Securities; provided, that the Company’s 6⅜% Senior Subordinated Notes due 2015, 7¹/2% Senior Subordinated Notes due 2016, 7¹/2% Senior Subordinated Notes due 2017, 7¹/4% Senior Subordinated Notes due 2018, 8% Senior Subordinated Notes due 2019 and 6³/4% Senior Subordinated Notes due 2020 outstanding on the date of this Indenture shall be deemed to rank on parity with the Securities and shall not be Senior Debt. Notwithstanding anything to the contrary in the foregoing sentence, Senior Debt will not include (w) any liability for federal, state, local or other taxes owed or owing by the Company, (x) any Indebtedness of the Company to any of its Subsidiaries or other Affiliates, (y) any trade payables or (z) any Indebtedness that is incurred in violation of this Indenture (other than Indebtedness under (i) the Credit Agreement or (ii) any other Credit Facility that is incurred on the basis of a representation by the Company to the applicable lenders that it is permitted to incur such Indebtedness under this Indenture).

     A “distribution” may consist of cash, securities or other property, by set-off or otherwise.

     All Designated Senior Debt now or hereafter existing and all other Obligations relating thereto shall not be deemed to have been paid in full unless the holders or owners thereof shall have received payment in full in cash (or other form of payment consented to by the holders of such Designated Senior Debt) with respect to such Designated Senior Debt and all other Obligations with respect thereto.

     Section 10.03 Liquidation; Dissolution; Bankruptcy.

          (a) Upon any payment or distribution of property or securities to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, or in an assignment for the benefit of creditors or any marshalling of the Company’s assets and liabilities:

               (1) the holders of Senior Debt of the Company shall be entitled to receive payment in full in cash of all Obligations in respect of such Senior Debt (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Debt, whether or not a claim for such interest would be allowed in such proceeding) before the Holders of Securities shall be entitled to receive any payment or distribution with respect to the Securities and related Obligations (except in each case that Holders of Securities may receive securities that are subordinated at least to the same extent as the Securities to Senior Debt and any securities issued in exchange for

Senior Debt and payments made from any defeasance trust created pursuant to Section 8.05 hereof provided, that the applicable deposit does not violate Article 8 or 10 of this Indenture); and

               (2) until all Obligations with respect to Senior Debt of the Company (as provided in subsection (a)(1) above) are paid in full in cash, any payment or distribution to which the Holders of Securities and the related Guarantees would be entitled shall be made to holders of Senior Debt of the Company (except that Holders of Securities and the related Guarantees may receive securities that are subordinated at least to the same extent as the Securities to Senior Debt and any securities issued in exchange for Senior Debt and payments made from any defeasance trust created pursuant to Section 8.05 hereof provided, that the applicable deposit does not violate Article 8 or 10 of this Indenture).

               (b) Upon any payment or distribution of property or securities to creditors of a Subsidiary Guarantor in a liquidation or dissolution of such Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such Subsidiary Guarantor or its property, or in an assignment for the benefit of creditors or any marshalling of such Subsidiary Guarantor’s assets and liabilities:

               (1) the holders of Senior Debt of such Subsidiary Guarantor shall be entitled to receive payment in full in cash of all Obligations in respect of such Senior Debt (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Debt, whether or not a claim for such interest would be allowed in such proceeding) before the Holders of Securities and the related Guarantees shall be entitled to receive any payment or distribution with respect to the Guarantee made by such Subsidiary Guarantor (except in each case that Holders of Securities and the related Guarantees may receive securities that are subordinated at least to the same extent as the Securities to Senior Debt and any securities issued in exchange for Senior Debt and payments made from any defeasance trust created pursuant to Section 8.05 hereof provided, that the applicable deposit does not violate Article 8 or 10 of this Indenture); and

               (2) until all Obligations with respect to Senior Debt of such Subsidiary Guarantor (as provided in subsection (b)(1) above) are paid in full in cash, any payment or distribution to which the Holders of Securities and the related Guarantees would be entitled shall be made to holders of Senior Debt of such Subsidiary Guarantor (except that Holders of Securities and the related Guarantees may receive securities that are subordinated at least to the same extent as the Securities to Senior Debt and any securities issued in exchange for Senior Debt and payments made from any defeasance trust created pursuant to Section 8.05 hereof provided, that the applicable deposit does not violate Article 8 or 10 of this Indenture).

     Under the circumstances described in this Section 10.03, the Company, any Subsidiary Guarantor or any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar person making any payment or distribution of cash or other property or securities is authorized or instructed to make any payment or distribution to which the Holders of the Securities and the related Guarantees would otherwise be entitled (other than securities that are subordinated at least to the same extent as the Securities to Senior Debt and any securities issued in exchange for Senior Debt and payments made from any defeasance trust referred to in the second parenthetical clause of each of clauses (a)(1), (b)(1), (a)(2) and (b)(2) above, which shall be delivered or paid to the Holders of Securities as set forth in such clauses) directly to the holders of the Senior Debt of the Company and any Subsidiary Guarantor, as applicable, (pro rata to such holders on the basis of the respective amounts of Senior Debt of the Company and any Subsidiary Guarantor, as applicable, held by such holders) or their Representatives, or to any trustee or trustees under any other indenture pursuant to which any such Senior Debt may have been issued, as their respective interests appear, to the extent necessary to pay all such Senior Debt in full, in cash or cash equivalents after giving effect to any concurrent payment, distribution or provision thereof or to or for the holders of such Senior Debt.

     To the extent any payment of or distribution in respect of Senior Debt (whether by or on behalf of the Company or any Subsidiary Guarantor, as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or distribution is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person, the Senior Debt or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred. To the extent the obligation to repay any Senior Debt is declared to be fraudulent, invalid or otherwise set aside under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then the obligation so declared

fraudulent, invalid or otherwise set aside (and all other amounts that would come due with respect thereto had such obligation not been so affected) shall be deemed to be reinstated and outstanding as Senior Debt for all purposes hereof as if such declaration, invalidity or setting aside had not occurred.

     Section 10.04 Default on Designated Senior Debt. The Company and the Subsidiary Guarantors may not make any payment (whether by redemption, purchase, retirements, defeasance or otherwise) upon or in respect of the Securities and the related Guarantees (other than securities that are subordinated at least to the same extent as the Securities to Senior Debt and any securities issued in exchange for Senior Debt and payments and other distributions made from any defeasance trust created pursuant to Section 8.05 hereof if the applicable deposit does not violate Article 8 or 10 of this Indenture) until all principal and other Obligations with respect to the Senior Debt of the Company have been paid in full if:

          (i) a default in the payment of any principal of, premium, if any, or interest on Designated Senior Debt occurs; or

          (ii) any other default occurs and is continuing with respect to Designated Senior Debt that permits, or with the giving of notice or passage of time or both (unless cured or waived) would permit, holders of the Designated Senior Debt as to which such default relates to accelerate its maturity and the Trustee receives a notice of the default (a “Payment Blockage Notice”) from the Company or the holders of any Designated Senior Debt. If the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until 360 days shall have elapsed since the date of commencement of the payment blockage period resulting from the immediately prior Payment Blockage Notice. No nonpayment default in respect of any Designated Senior Debt that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice.

     The Company shall resume payments on and distributions in respect of the Securities and any Subsidiary Guarantor shall resume making payments and distributions pursuant to the Guarantees upon:

               (1) in the case of a default referred to in Section 10.04(i) hereof the date upon which the default is cured or waived, or

               (2) in the case of a default referred to in Section 10.04(ii) hereof, the earliest of (1) the date on which such nonpayment default is cured or waived, (2) the date the applicable Payment Blockage Notice is retracted by written notice to the Trustee and (3) 90 days after the date on which the applicable Payment Blockage Notice is received unless (A) the maturity of any Designated Senior Debt has been accelerated or (B) a Default or Event of Default under Section 6.01(9) or (10) has occurred and is continuing, if this Article otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition.

     Section 10.05 Acceleration of Securities. If payment of the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Debt of the acceleration.

     Section 10.06 When Distribution Must be Paid Over. In the event that the Trustee or any Holder receives any payment or distribution of or in respect of any Obligations with respect to the Securities or the Guarantees at a time when such payment or distribution is prohibited by Section 10.03 or Section 10.04 hereof, such payment or distribution shall be held by the Trustee (if the Trustee has actual knowledge that such payment or distribution is prohibited by Section 10.03 or Section 10.04) or such Holder, in trust for the benefit of, and shall be paid forthwith over and delivered to, the holders of Senior Debt as their interests may appear or their Representative under the indenture or other agreement (if any) pursuant to which such Senior Debt may have been issued, as their respective interests may appear, for application to the payment of all Obligations with respect to Senior Debt remaining unpaid to the extent necessary to pay such Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt.

     With respect to the holders of Senior Debt, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article 10, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt, and, except as provided in Section 10.12, shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of Holders of Securities or the Company,

the Subsidiary Guarantors or any other Person money or assets to which any holders of Senior Debt shall be entitled by virtue of this Article 10, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee.

     Section 10.07 Notice by Company. The Company and the Subsidiary Guarantors shall promptly notify the Trustee and the Paying Agent of any facts known to the Company or any Subsidiary Guarantor that would cause a payment of any Obligations with respect to the Securities or the related Guarantees to violate this Article, but failure to give such notice shall not affect the subordination of the Securities and the related Guarantees to the Senior Debt as provided in this Article.

     Section 10.08 Subrogation. After all Senior Debt is paid in full and until the Securities are paid in full, Holders of Securities and the related Guarantees shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Securities and the Guarantees) to the rights of holders of Senior Debt to receive distributions and payments applicable to Senior Debt to the extent that distributions and payments otherwise payable to the Holders of Securities and the related Guarantees have been applied to the payment of Senior Debt. A payment or distribution made under this Article to holders of Senior Debt that otherwise would have been made to Holders of Securities and the related Guarantees is not, as between the Company and Holders of Securities, a payment by the Company on the Securities.

     Section 10.09 Relative Rights. This Article defines the relative rights of Holders of Securities and the related Guarantees and holders of Senior Debt. Nothing in this Indenture shall:

          (1) impair, as between the Company and Holders of Securities, the obligation of the Company, which is absolute and unconditional, to pay principal of and interest on the Securities in accordance with their terms;

          (2) affect the relative rights of Holders of Securities and the related Guarantees and creditors of the Company other than their rights in relation to holders of Senior Debt; or

          (3) prevent the Trustee or any Holder from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Debt to receive distributions and payments otherwise payable to Holders of Securities and the related Guarantees.

     If the Company fails because of this Article to pay principal of or interest on a Security on the due date, the failure is still a Default or Event of Default.

     Section 10.10 Subordination May Not be Impaired by Company or the Subsidiary Guarantors. No right of any present or future holders of any Senior Debt to enforce subordination as provided in this Article 10 will at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or any Subsidiary Guarantor or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company or any Subsidiary Guarantor with the terms of this Indenture, regardless of any knowledge thereof that any such holder of Senior Debt may have or otherwise be charged with. The provisions of this Article 10 are intended to be for the benefit of, and shall be enforceable directly by, the holders of Senior Debt.

     Section 10.11 Payment, Distribution or Notice to Representative. Whenever a payment or distribution is to be made or a notice given to holders of Senior Debt, the distribution may be made and the notice given to their Representative.

     Upon any payment or distribution of assets or securities of the Company or any Subsidiary Guarantor referred to in this Article 10, the Trustee and the Holders of Securities and the related Guarantees shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any payment or distribution to the Trustee or to the Holders of Securities and the related Guarantees for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Debt and other Indebtedness of the Company or any Subsidiary Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 10.

     Section 10.12 Rights of Trustee and Paying Agent. Notwithstanding the provisions of this Article 10 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Securities and the Guarantees, unless the Trustee shall have received at its Corporate Trust Office at least one Business Day prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Securities or Guarantees to violate this Article, which notice shall specifically refer to Section 10.03 or 10.04 hereof. Only the Company or a Representative may give the notice. Nothing in this Article 10 shall impair the claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof.

     The Trustee in its individual or any other capacity may hold Senior Debt with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights.

     Section 10.13 Authorization to Effect Subordination. Each Holder by the Holder’s acceptance thereof authorizes and directs the Trustee on the Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 10, and appoints the Trustee to act as the Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 6.09 hereof at least 30 days before the expiration of the time to file such claim, each lender under the Credit Agreement is hereby authorized to file an appropriate claim for and on behalf of the Holders of the Securities and the related Guarantees.

     Section 10.14 Amendments. No amendment may be made to the provisions of or the definitions of any terms appearing in this Article 10, or to the provisions of Section 6.02 relating to the Designated Senior Debt, that adversely affects the rights of any holder of Senior Debt then outstanding unless the holders of such Senior Debt (or any group or Representative authorized to give a consent) consent to such change.

     Section 10.15 No Waiver of Subordination Provisions. Without in any way limiting the generality of Section 10.09 of this Indenture, the holders of Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders, without incurring responsibility to the Holders and without impairing or releasing the subordination provided in this Article 10 or the obligations hereunder of the Holders to the holders of Senior Debt, do any one or more of the following: (a) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt or any instrument evidencing the same or any agreement under which Senior Debt is outstanding or secured; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt; (c) release any Person liable in any manner for the collection of Senior Debt; and (d) exercise or refrain from exercising any rights against the Company and each Subsidiary Guarantor and any other Person.

ARTICLE 11
The Guarantees

     Section 11.01 The Guarantees. Each of the Subsidiary Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Securities or the obligations of the Company hereunder or thereunder, that: (a) the principal of and premium, if any, and interest, on the Securities shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on premium and interest, on the Securities, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, that the same shall 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 Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately. The Subsidiary Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities 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 of the

Subsidiary Guarantors 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 Guarantee shall not be discharged except by complete performance of the obligations contained in the Securities and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company or the Subsidiary Guarantors, or any Custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the Subsidiary Guarantors, any amount paid by either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each of the Subsidiary Guarantors agrees that it shall not be entitled to any right of subrogation in relation to the Holders of Securities in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each of the Subsidiary Guarantors further agrees that, as between the Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6, such obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of this Guarantee. The Subsidiary Guarantors shall have the right to seek contribution from any Subsidiary Guarantor not paying so long as the exercise of such right does not impair the rights of the Holders under the Guarantees.

     Section 11.02 Execution and Delivery of Guarantees. To evidence its Guarantee set forth in Section 11.01, each of the Subsidiary Guarantors hereby agrees that a notation of such Guarantee substantially in the form of Exhibit B shall be endorsed by an officer of such Subsidiary Guarantor on each Security authenticated and delivered by the Trustee, that this Indenture shall be executed on behalf of such Subsidiary Guarantor by an Officer thereof.

     Each Subsidiary Guarantor hereby agrees that its Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee.

     If an Officer whose signature is on this Indenture or on the applicable Guarantee no longer holds that office at the time the Trustee authenticates the Security on which such Guarantee is endorsed, such Guarantee shall be valid nevertheless.

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

     Section 11.03 Subsidiary Guarantors May Consolidate, etc., on Certain Terms. No Subsidiary Guarantor may consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the Surviving Person) another Person, whether or not affiliated with such Subsidiary Guarantor, unless:

          (a) subject to the provisions of Section 11.04 hereof, the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee in respect of the Securities, this Indenture and such Subsidiary Guarantor’s Guarantee;

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

          (c) such transaction does not violate any of Sections 4.03, 4.07, 4.08, 4.09, 4.11, 4.12, 4.13, 4.14, 4.16 and 4.17.

Notwithstanding the foregoing, none of the Subsidiary Guarantors shall be permitted to consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person), another corporation, Person or entity pursuant to the preceding sentence if such consolidation or merger would not be permitted by Section 5.01 hereof.

     In case of any such consolidation or merger and upon the assumption by the successor corporation, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Guarantee endorsed upon the Securities and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by such Subsidiary Guarantor, such successor corporation shall succeed to and be

substituted for such Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. Such successor corporation thereupon may cause to be signed any or all of the Guarantees to be endorsed upon all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof.

     Except as set forth in Articles 4 and 5 hereof, nothing contained in this Indenture or in any of the Securities shall prevent any consolidation or merger of any Subsidiary Guarantor with or into the Company or another Subsidiary Guarantor, or shall prevent any sale or conveyance of the property of any Subsidiary Guarantor as an entirety or substantially as an entirety to the Company or any Subsidiary Guarantor.

     Section 11.04 Releases of Guarantees. In the event of a sale or other disposition of all or substantially all of the assets of any Subsidiary Guarantor or a sale or other disposition of all of the capital stock of any Subsidiary Guarantor, to any corporation or other Person (including an Unrestricted Subsidiary) by way of merger, consolidation, or otherwise, in a transaction that does not violate any of the covenants of this Indenture, then such Subsidiary Guarantor (in the event of a sale or other disposition, by way of such merger, consolidation or otherwise, of all the capital stock of such Subsidiary Guarantor) shall be released and relieved of any obligations under its Guarantee and such acquiring corporation or other Person (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor), if other than a Subsidiary Guarantor, shall have no obligation to assume or otherwise become liable under such Guarantee. Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture, including without limitation Section 4.10, such Subsidiary Guarantor shall ipso facto be released from its obligations under its Guarantee and the Trustee shall execute any documents reasonably required in order to evidence the release of any Subsidiary Guarantor from its obligations under its Guarantee.

     Any Subsidiary Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Securities and for the other obligations of such Subsidiary Guarantor under this Indenture as provided in this Article 11.

     Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in accordance with the terms of this Indenture shall be released from and relieved of its obligations under its Guarantee.

     Section 11.05 Limitation on Subsidiary Guarantor Liability. For purposes hereof, each Subsidiary Guarantor’s liability shall be that amount from time to time equal to the aggregate liability of such Subsidiary Guarantor thereunder, but shall be limited to the lesser of (i) the aggregate amount of the Obligations of the Company under the Securities and this Indenture and (ii) the amount, if any, which would not have (A) rendered such Subsidiary Guarantor “insolvent” (as such term is defined in the Bankruptcy Code and in the Debtor and Creditor Law of the State of New York) or (B) left it with unreasonably small capital at the time its Guarantee of the Securities was entered into, after giving effect to the incurrence of existing Indebtedness immediately prior to such time; provided, that, it shall be a presumption in any lawsuit or other proceeding in which such Subsidiary Guarantor is a party that the amount guaranteed pursuant to its Guarantee is the amount set forth in clause (i) above unless any creditor, or representative of creditors of such Subsidiary Guarantor, or debtor in possession or trustee in bankruptcy of such Subsidiary Guarantor, otherwise proves in such a lawsuit that the aggregate liability of such Subsidiary Guarantor is limited to the amount set forth in clause (ii). In making any determination as to the solvency or sufficiency of capital of a Subsidiary Guarantor in accordance with the previous sentence, the right of such Subsidiary Guarantor to contribution from other Subsidiary Guarantors and any other rights such Subsidiary Guarantor may have, contractual or otherwise, shall be taken into account.

     Section 11.06 “Trustee” to Include Paying Agent. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee” as used in Article 10 and this Article 11 shall in such case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in Article 10 and this Article 11 in place of the Trustee.

     Section 11.07 Subordination of Guarantees. The obligations of each of the Subsidiary Guarantors under its Guarantee pursuant to this Article 11 shall be junior and subordinated to the Senior Debt of the Subsidiary Guarantor pursuant to Article 10 hereof. For the purposes of the foregoing sentence, the Trustee and the Holders shall have the right to receive and/or retain payments or distributions by or on behalf of any of the Subsidiary Guarantors only at such times as they may receive and/or retain payments in respect of the Securities pursuant to this Indenture, including Article 10 hereof.

ARTICLE 12

kept by the Registrar. Any notice or communication shall also be so mailed to any Person described in TIA § 313(c), to the extent required by the TIA. Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders.

     If a notice or communication is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

     If the Company or any Subsidiary Guarantor mails a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time.

     Section 12.03 Communication by Holders of Securities with Other Holders of Securities. Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Securities. The Company, the Subsidiary Guarantors, the Trustee, the Registrar and anyone else shall have the protection of TIA § 312(c).

     Section 12.04 Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Company or any Subsidiary Guarantor to the Trustee to take any action under this Indenture, the Company or such Subsidiary Guarantor, as the case may be, shall furnish to the Trustee:

          (a) an Officers’ Certificate in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 12.05 hereof) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been complied with; and

          (b) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 12.05 hereof) stating that, in the opinion of such counsel, all such conditions precedent and covenants have been complied with.

     Section 12.05 Statements Required in Certificate or Opinion.

          (a) a statement that the Person making such certificate or opinion has read such covenant or condition;

          (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

          (c) a statement that, in the opinion of such Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with; and

No director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company under the Securities or this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Securities, by accepting a Security, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the Commission that such a waiver is against public policy.

     Section 12.08 Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE SECURITIES AND THE GUARANTEES.

     Section 12.09 No Adverse Interpretation of Other Agreements.

     Section 12.11 Severability. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

     Section 12.12 Counterpart Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

     Section 12.13 Table of Contents, Headings, etc. The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

     Section 12.14 Actions on Other than Business Days. Unless otherwise provided herein, if the date for making any payment or the last date for the performance of any act or the exercising of any right, as provided in this Indenture, is not a Business Day, such payment may be made, act performed or right exercised on the next succeeding Business Day, with the same force and effect as if made or done on the nominal date provided therefor, and, with respect to any payment so made, no interest shall accrue for the period between such nominal date and the date of payment.

Guarantee

     Each of the Subsidiary Guarantors hereby, jointly and severally and unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, dated as of May 25, 2011, among Range Resources Corporation, a Delaware corporation (the “Company”), the Subsidiary Guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”) (as it may be amended or supplemented, the “Indenture”), the Securities or the obligations of the Company hereunder or thereunder, that: (a) the principal of, and premium, if any, and interest on, the Securities shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and interest on premium and interest on, the Securities, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, that same shall 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 Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately.

     The obligations of the Subsidiary Guarantors to the Holders of Securities and to the Trustee pursuant to this Guarantee and the Indenture (including the subordination provisions thereof) are expressly set forth in Article 11 of the Indenture, and reference is hereby made to such Indenture for the precise terms of this Guarantee. The terms of Article 11 of the Indenture are incorporated herein by reference.

     This is a continuing Guarantee and shall remain in full force and effect and shall be binding upon each of the Subsidiary Guarantors and its respective successors and assigns to the extent set forth in the Indenture until full and final payment of all of the Company’s Obligations under the Securities and the Indenture and shall inure to the benefit of the Trustee and the Holders of Securities and their successors and assigns and, in the event of any transfer or assignment of rights by any Holder of Securities or the Trustee, the rights and privileges herein conferred upon that party shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof. Notwithstanding the foregoing, any Subsidiary Guarantor that satisfies the provisions of Section 11.04 of the Indenture shall be released of its obligations hereunder. This is a Guarantee of payment and not a, guarantee of collection.

     This Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication on the Security upon which this Guarantee is noted shall have been executed by the Trustee under the Indenture by the manual signature of one of its authorized officers.

     For purposes hereof, each Subsidiary Guarantor’s liability will be that amount from time to time equal to the aggregate liability of such Subsidiary Guarantor hereunder but shall be limited to the lesser of (i) the aggregate amount of the obligations of the Company under the Securities and the Indenture and (ii) the amount, if any, which would not have (A) rendered such Subsidiary Guarantor “insolvent” (as such term is defined in the federal Bankruptcy Code and in the Debtor and Creditor law of the State of New York) or (B) left it with unreasonably small capital at the time its Guarantee was entered into, after giving effect to the incurrence of existing Indebtedness immediately prior to such time; provided, that, it shall be a presumption in any lawsuit or other proceeding in which such Subsidiary Guarantor is a party that the amount guaranteed pursuant to its Guarantee is the amount set forth in clause (i) above unless any creditor, or representative of creditors of such Subsidiary Guarantor, or debtor in possession or trustee in bankruptcy of such Subsidiary Guarantor, otherwise proves in such a lawsuit that the aggregate liability of such Subsidiary Guarantor is limited to the amount set forth in clause (ii). The Indenture provides that, in making any determination as to the solvency or sufficiency of capital of a Subsidiary Guarantor in accordance with the previous sentence, the right of such Subsidiary Guarantor to contribution from other Subsidiary Guarantors and any other rights such Subsidiary Guarantor may have, contractual or otherwise, shall be taken into account.

[REVERSE SIDE OF NOTE]

RANGE RESOURCES CORPORATION

     1. Indenture.

     This is one of the Securities issued under an Indenture dated as of May 25, 2011 (as supplemented or amended from time to time, the “Indenture”), among the Company, the Subsidiary Guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as Trustee, which Securities have been designated by supplemental indenture thereto as the 5³/4% Senior Subordinated Notes due 2021. Capitalized terms used herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture will control.

     The Notes are general unsecured obligations of the Company. The Indenture provides for the initial issuance of $500,000,000 principal amount of Notes, but additional Notes may be issued pursuant to the Indenture, and the originally issued Notes and all such additional Notes vote together for all purposes as a single class.

     2. Principal and Interest.

     The Company promises to pay the principal of this Note on June 1, 2021.

     The Company promises to pay interest on the principal amount of this Note on each interest payment date, as set forth on the face of this Note, at the rate of 5³/4% per annum. Interest will be payable semiannually (to the holders of record of the Notes at the close of business on the May 15 and November 15 immediately preceding the relevant interest payment date) on each interest payment date, commencing December 1, 2011.

     Interest on this Note will accrue from the most recent date to which interest has been paid on this Note (or, if there is no existing default in the payment of interest and if this Note is authenticated between a regular record date and the next interest payment date, from such interest payment date) or, if no interest has been paid on the Notes, from May 25, 2011. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

     The Company will pay interest on overdue principal, premium, if any, and, to the extent lawful, interest at a rate per annum that is 1% in excess of 5³/4%. Interest not paid when due and any interest on principal, premium or interest not paid when due will be paid to the Persons that are Holders on a special record date, which will be the close of business on the 15th day preceding the date fixed by the Company for the payment of such interest, whether or not such day is a Business Day. At least 15 days before a special record date, the Company will send to each Holder and to the Trustee a notice that sets forth the special record date, the payment date and the amount of interest to be paid.

     3. Optional Redemption.

     (a) Except as provided in paragraphs 3(b) and 3(c) below, the Notes are not redeemable at the Company’s option prior to June 1, 2016. From and after June 1, 2016, the Notes will be subject to redemption at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on June 1 of the years indicated below:

Year		Percentage
2016			102.875	%
2017			101.917	%
2018			100.958	%
2019 and thereafter			100.000	%

     (b) Prior to June 1, 2014 the Company may, at its option, on any one or more occasions, redeem up to 35% of the original aggregate principal amount of Notes at a redemption price equal to 105.750% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, with the net proceeds of sales of public Equity Interests of the Company; provided that at least 65% of the original aggregate principal amount of Notes remain outstanding immediately after the occurrence of such redemption; and provided, further, that any such redemption shall occur within 60 days after the date of the closing of the related sale of such Equity Interests.

     (c) Prior to June 1, 2016, the Company may redeem all or, from time to time, any part of the Notes upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount thereof plus the Make-Whole Premium plus accrued and unpaid interest, if any, to the redemption date.

     “Make-Whole Premium” means, with respect to a Note at any redemption date, the excess of (A) the present value at such time of (1) the redemption price, excluding accrued interest, of such note at June 1, 2016, (as set forth in the table in paragraph 3(a) above) plus (2) all required interest payments, excluding accrued interest, due on such Note through June 1, 2016, computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of such Note.

     “Treasury Rate” means the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two Business Days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source or similar market data)) most nearly equal to the period from the redemption date to June 1, 2016; provided, however, that if the period from the redemption date to June 1, 2016 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of

United States Treasury securities for which such yields are given, except that if the period from the redemption date to June 1, 2016 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

     If the optional redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the Person in whose name the Note is registered at the close of business on such record date, and no additional interest will be payable to Holders whose Notes will be subject to redemption by the Company.

     4. Mandatory Redemption.

     Except as set forth in paragraph 5 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

     5. Repurchase at Option of Holder.

     (a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof, and in a minimum amount of $1,000) of such Holder’s Notes subject to and as provided in the Indenture.

     (b) If the Company or a Restricted Subsidiary consummates any Asset Sales permitted by the Indenture, when the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall make an Asset Sale Offer to purchase the maximum principal amount of Notes and any other pari passu Indebtedness to which the Asset Sale Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to, in the case of the Notes, 100% of the principal amount thereof, plus accrued and unpaid interest thereon to the date of purchase or, in the case of any pari passu Indebtedness, 100% of the principal amount thereof (or with respect to discount pari passu Indebtedness, the accreted value thereof) on the date of purchase, in each case, subject to and as provided in the Indenture.

     6. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in integral multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest will cease to accrue on the aggregate principal amount of the Notes called for redemption.

     7. Registered Form; Denominations; Transfer; Exchange.

     The Notes are in registered form without coupons in minimum denominations of $1,000 principal amount and any multiple of $1,000 in excess thereof. A Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Trustee may require a Holder to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Pursuant to the Indenture, there are certain periods during which the Trustee will not be required to issue, register the transfer of or exchange any Note or certain portions of a Note.

     8. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes.

     9. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or the tender offer or exchange offer for, such Notes), and any existing Default or Event of Default under, or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended on supplemented to, among other things, cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, or to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.

     10. Defaults and Remedies. The Indenture provides that if an Event of Default (other than with respect to bankruptcy events) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately, and in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable without further action or notice. Holders of the Notes may not enforce the Indenture or the Notes except as provided in the Indenture.

     11. Subordination. The Notes are subordinated to Senior Debt of the Company as provided in the Indenture. To the extent provided in the Indenture, Senior Debt must be paid before the Notes may be paid. The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by the Notes, including, but not limited to, the payment of principal of, premium, if any, and interest on the Notes, and any other payment Obligation of the Company in respect of the Notes is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment in full in cash of all Senior Debt of the Company (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed) and authorizes the Trustee to give effect and appoints the Trustee as attorney-in-fact for such purpose.

     12. Trustee Dealings with Company. The Indenture contains certain limitations on the rights of the Trustee, should it become a creditor of the Company, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign.

     13. No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

     14. Authentication.

     This Note is not valid until the Trustee (or Authenticating Agent) signs the certificate of authentication on this Note.

     15. Governing Law.

     This Note shall be governed by, and construed in accordance with, the laws of the State of New York.

     16. Abbreviations.

     Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian) and U/G/M/A/ (= Uniform Gifts to Minors Act).

     The Securities were offered and sold pursuant to a prospectus supplement, dated May 11, 2011, filed with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b) on May 12, 2011, to a prospectus dated May 11, 2011 (such prospectus, as amended and supplemented by the prospectus supplement, the “Prospectus”), included in a Registration Statement on Form S-3 (Registration No. 333-174119) (as amended, the “Registration Statement”), which Registration Statement became effective upon filing with the Commission pursuant to Rule 462(e) under the Securities Act.

Directors of the Company (the Board of Directors, or to the extent permitted by Section 141 of the General Corporation Law of the State of Delaware (the “DGCL”), a duly constituted and acting committee thereof, being referred to herein as the “Board”) relating to the registration of the Securities and related matters, (iii) the Registration Statement, (iv) the Prospectus, (v) the Indenture, and (vi) such other certificates, instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed. In addition, we reviewed such questions of law as we considered appropriate.

     As to any facts material to the opinions contained herein, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Company.

     In connection with rendering the opinions set forth below, we have assumed that (i) all information contained in all documents reviewed by us is true and correct; (ii) all signatures on all documents examined by us are genuine; (iii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the originals of those documents; (iv) each natural person signing any document reviewed by us had the legal capacity to do so; (v) each person signing in a representative capacity any document reviewed by us had authority to sign in such capacity; (vi) all Securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Prospectus and the Registration Statement; (vii) the Indenture was duly authorized, executed and delivered by the parties thereto in substantially the form reviewed by us or with changes that do not affect the opinions given hereunder; and (viii) the Underwriting Agreement has been duly authorized and validly executed and delivered by the Company and the other parties thereto.

     Based upon such examination and review and the foregoing assumptions, we are of the opinion that (1) the Notes have been duly authorized, executed and issued by the Company, and, assuming that the Notes have been duly authenticated by the Trustee, constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms and will be entitled to the benefits of the Indenture, and (2) the Guarantees have been duly authorized, executed and issued by the Subsidiary Guarantors, and constitute valid and binding obligations of the respective Subsidiary Guarantors, enforceable against the respective Subsidiary Guarantors in accordance with their terms and will be entitled to the benefits of the Indenture.

     We express no opinions concerning (i) the validity or enforceability of any provisions contained in the Indenture that purport to waive or not give effect to rights to notices, defenses,

subrogation or other rights or benefits that cannot be effectively waived under applicable law or (ii) the enforceability of indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws.

     The foregoing opinions are limited in all respects to the laws of the DGCL (including the applicable provisions of the Delaware Constitution and the reported judicial decisions interpreting these laws), the laws of the State of New York and the federal laws of the United States of America as in effect on the date hereof, and we undertake no duty to update or supplement the foregoing opinions to reflect any facts or circumstances that may hereafter come to our attention or to reflect any changes in any law that may hereafter occur or become effective. We do not express any opinions as to the laws of any other jurisdiction.

To effect such filing (by incorporation by reference), we hereby consent to the filing of this opinion letter as an exhibit to a current report on Form 8-K. In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act and the rules and regulations of the Commission issued thereunder.

NEWS RELEASE

RANGE ANNOUNCES EARLY TENDER RESULTS FOR ITS CASH TENDER OFFERS
AND CONSENT SOLICITATIONS FOR ITS
6-3/8% SENIOR SUBORDINATED NOTES DUE 2015 AND
7-1/2% SENIOR SUBORDINATED NOTES DUE 2016

FORT WORTH, TEXAS, MAY 25, 2011...RANGE RESOURCES CORPORATION (NYSE: RRC) announced today that it had received, as of 5:00 p.m., New York City time, on May 24, 2011 (the “Consent Expiration”), tenders and consents from holders of 72.61% of its outstanding $150,000,000 aggregate principal amount of 6-3/8% senior subordinated notes due 2015 (CUSIP No. 75281AAF6) (the “2015 Notes”) and 79.51% of its outstanding $250,000,000 aggregate principal amount of 7-1/2% senior subordinated notes due 2016 (CUSIP No. 75281AAG4) (the “2016 Notes,” and collectively with the 2015 Notes, the “Notes”), both in connection with its previously announced tender offers (the “Offers”) and consent solicitations for the Notes, which commenced on May 11, 2011, and are described in the Offer to Purchase and Consent Solicitation Statement dated May 11, 2011 (the “Offer to Purchase”).

Range intends to execute later today supplemental indentures (the “Supplemental Indentures”) with respect to each of the indentures governing the Notes, which will eliminate most of the covenants and certain default provisions applicable to the Notes. Each Supplemental Indenture will not become operative until a majority in aggregate principal amount of each series of the Notes has been purchased by Range pursuant to the terms of the Offers, which is expected to occur today.

Range’s obligation to accept for purchase, and to pay for, any Notes pursuant to the Offers is subject to a number of conditions that are set forth in the Offer to Purchase, including the closing today of Range’s previously announced public offering of $500,000,000 of 5-3/4% senior subordinated notes due 2021. The “Total Consideration” for each $1,000 principal amount of Notes that were validly tendered and not validly withdrawn prior to the Consent Expiration is $1,023.75 with respect to the 2015 Notes and $1,040.00 with respect to the 2016 Notes, each of which includes a consent payment of $20.00 per $1,000 principal amount of Notes. Holders will also receive accrued and unpaid interest from the last interest payment on the applicable Notes.

Holders who validly tender (and do not validly withdraw) their Notes after the Consent Expiration and prior to the expiration of the Offers will be entitled to receive consideration equal to $1,003.75 for each $1,000 principal amount of 2015 Notes and $1,020.00 for each $1,000 principal amount of 2016 Notes, plus any accrued and unpaid interest on the Notes up to, but not including, the payment date for such Notes accepted for purchase. Holders of Notes tendered after the Consent Expiration will not receive a consent payment. The tender offers will expire at 11:59 p.m., New York City Time, on Wednesday, June 8, 2011, unless extended by Range in its sole discretion.

Any Notes not tendered and purchased pursuant to the Offers will remain outstanding and the holders will be subject to the terms of the Supplemental Indentures even though they did not consent to the amendments.

Range has engaged J.P. Morgan Securities LLC to act as the exclusive dealer manager and solicitation agent in connection with the Offers. Questions regarding the terms of the Offers may be directed to J.P. Morgan Securities LLC, Syndicate Desk, at (800) 261-5767 (US toll-free). The complete terms and conditions of the Offers are described in the Offer to Purchase and Consent Solicitation Statement dated May 11, 2011, copies of which may be obtained from MacKenzie Partners Inc., the depositary and information agent for the Offers, at (800) 322-2885 (US toll free).

This press release does not constitute an offer to purchase the Notes or a solicitation of consents to amend the related indenture. The tender offers are made solely pursuant to the Offer to Purchase and Consent Solicitation Statement dated May 11, 2011. The tender offers are not being made to holders of Notes in any jurisdiction in which the making or acceptance thereof would not be in compliance with the securities, blue sky or other laws of such jurisdiction.

These statements are based on assumptions and estimates that Range’s management believes are reasonable based on currently available information; however, management’s assumptions and Range’s future performance are subject to a wide range of business risks and uncertainties, and there is no assurance that these goals and projections can or will be met. Any number of factors could cause actual results to differ materially from those in the forward-looking statements, including, but not limited to, the volatility of oil and gas prices, the results of our hedging transactions, the costs and results of drilling and operations, the timing of production, mechanical and other inherent risks associated with oil and gas production, weather, the availability of drilling equipment, changes in interest rates, litigation, uncertainties about reserve estimates, environmental risks and regulatory changes. Range undertakes no obligation to publicly update or revise any forward-looking statements. Further information on risks and uncertainties is available in Range’s filings with the SEC, which are incorporated herein by reference.
