RECITATIONS OF THE COMPANY

WHEREAS, the Company, WOGC and the Trustee have heretofore executed and delivered the Original Indenture to provide for the issuance of the Company’s senior debt securities to be issued in one or more series (herein called the “Securities”);

WHEREAS, the Company desires to provide for the issuance of a series of Securities to be designated as the “6.25% Senior Notes due 2023” (the “Notes”), and to set forth the form and terms thereof;

WHEREAS, the Company proposes in and by this Fourth Supplemental Indenture to supplement and amend the Original Indenture, but only insofar as it will apply to the Notes; and

WHEREAS, all action on the part of the Company necessary to authorize the creation and issuance of the Notes, and all action on the part of each of the Guarantors necessary to authorize its guarantee of the Notes under the Original Indenture and this Fourth Supplemental Indenture (the Original Indenture, as supplemented and amended by this Fourth Supplemental Indenture, being hereinafter called the “Indenture”), has been duly taken.

NOW, THEREFORE, THIS FOURTH SUPPLEMENTAL INDENTURE WITNESSETH:

That, in order to establish the designation, form and terms of, and to authorize the authentication and delivery of the Notes and the Guarantees of the Guarantors, and in consideration of the acceptance of the Notes and the Guarantees by the Holders thereof and

of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE 1

DEFINITIONS AND INCORPORATION

BY REFERENCE

Section 1.01 Definitions.

(a) Capitalized terms used herein and not otherwise defined shall have the respective meanings assigned thereto in the Original Indenture.

(b) Section 101 of the Original Indenture is amended and supplemented, with respect to the Notes, by inserting or restating, as the case may be, in their appropriate alphabetical position, the following definitions:

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

(1) the sum of:

(a) discounted future net revenue from proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with Commission guidelines before any state or federal income taxes, as estimated in a reserve report prepared as of the end of the Company’s most recently completed fiscal year, which reserve report is prepared or reviewed by independent petroleum engineers as to reserves accounting for at least 80% of all such discounted future net revenue and by the Company’s petroleum engineers with respect to any other such reserves covered by such report, as increased by, as of the date of determination, the discounted future net revenue from:

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

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

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

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

(iv) reductions in the estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such year-end reserve report since the date of such year-end reserve report

attributable to downward determinations of estimates of proved crude oil and natural gas reserves due to exploration, development or exploitation, production or other activities conducted or otherwise occurring since the date of such year-end reserve report,

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

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

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

(d) the greater of (I) the net book value on a date no earlier than the date of the Company’s latest annual or quarterly financial statements or (II) the appraised value, as estimated by independent appraisers, of other tangible assets of the Company and its Restricted Subsidiaries as of a date no earlier than the date of the Company’s latest audited financial statements;

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

(a) noncontrolling interests;

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

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

(d) the discounted future net revenue, calculated in accordance with Commission guidelines (utilizing the same prices utilized in the Company’s year-end reserve report), attributable to reserves that are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified with respect thereto; and

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

Any calculation of Adjusted Consolidated Net Tangible Assets shall be determined on a pro forma basis in a manner consistent with the pro forma adjustments contained in the definition of Fixed Charge Coverage Ratio. If the Company changes its method of accounting for its oil and gas properties from the successful efforts method to the full cost method or a similar method of accounting, ACNTA will continue to be calculated as if the Company were still using the successful efforts method of accounting.

“Acquired Debt” means, with respect to any specified Person:

(1) Indebtedness, Disqualified Stock or preferred stock of any other Person existing at the time such other Person was merged with or into or became a Subsidiary of such specified Person, whether or not such Indebtedness, Disqualified Stock or preferred stock is incurred or issued in connection with, or in contemplation of, such other Person merging with or into, or becoming a Subsidiary of, such specified Person; provided, however, that Indebtedness, Disqualified Stock or preferred stock of such acquired Person which is redeemed, defeased, retired or otherwise repaid at the time of or substantially contemporaneously with the consummation of the transactions by which such Person merges with or into or becomes a Subsidiary of such Person shall not be Acquired Debt; and

(2) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person.

(2) 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

“Asset Sale” means:

(1) the sale, lease, conveyance or other disposition of any properties or assets (including by way of a Production Payment or Sale And Leaseback Transaction); provided that the sale, lease, conveyance or other disposition of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole will be governed by the provisions of Section 4.15 of this Fourth Supplemental Indenture and/or the provisions of Section 5.01 of this Fourth Supplemental Indenture and not by the provisions of Section 4.10 of this Fourth Supplemental Indenture; and

(2) the issuance of Equity Interests in any of the Company’s Restricted Subsidiaries or the sale by the Company or any of the Company’s Restricted Subsidiaries of Equity Interests in any of the Company’s Restricted Subsidiaries (other than directors’ qualifying shares or shares required by Applicable Law to be held by a Person other than the Company or a Restricted Subsidiary).

THE NOTES

Section 2.01 Creation and Form.

Pursuant to Sections 201 and 301 of the Original Indenture, there is hereby created a new series of Securities designated as the “6.25% Senior Notes due 2023” (which are herein referred to as the “Notes” for purposes of this Fourth Supplemental Indenture). The Notes shall be subject to the provisions of the Appendix hereto, shall be substantially in the form specified in Exhibit A to this Fourth Supplemental Indenture, shall have the terms set forth therein and shall be entitled to the benefits of the other provisions of the Original Indenture as modified by this Fourth Supplemental Indenture and specified herein.

Section 2.02 Execution and Authentication.

On the Issue Date, the Trustee shall authenticate and deliver $750,000,000 of Initial Notes and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Additional Notes for original issue, in each case upon the Trustee’s receipt of a Company Order in accordance with Section 303 of the Original Indenture. Such order shall specify the aggregate principal amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated and, in the case of an issuance of Additional Notes pursuant to Section 2.05 of this Fourth Supplemental Indenture after the Issue Date, shall certify that such issuance is in compliance with such Section 2.05 and Section 4.09 hereof. The Notes shall be issued initially in the form of Global Securities, for which The Depository Trust Company shall act as Depositary, as more fully set forth in the Appendix. Notes in the form of Global Securities shall bear the legends set forth on the form of Note attached hereto and such other legends as may be specified in the Appendix.

Section 2.03 Outstanding Notes.

Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. Except as otherwise provided in TIA §316(a), a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If a Note is replaced pursuant to Section 306 of the Original Indenture, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser.

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

Notes purchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be retired and cancelled, at the Company’s option. Notes purchased by a third party pursuant to the Section 4.15 will have the status of Notes issued and outstanding.

Section 2.04 CUSIP Numbers.

The Company in issuing the Notes may use “CUSIP” numbers and corresponding “ISINs” (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers and corresponding “ISINs” in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers.

Section 2.05 Issuance of Additional Notes.

The Company shall be entitled, subject to its compliance with Section 4.09 of this Fourth Supplemental Indenture, to issue Additional Notes under this Indenture which shall have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance and issue price. The Initial Notes issued on the Issue Date and any Additional Notes shall be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided, however, that if any Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, such Additional Notes will be issued as a separate series under this Indenture and will have a separate CUSIP number and ISIN from the Initial Notes.

ARTICLE 3

The Notes shall be subject to redemption and purchase by the Company pursuant to the provisions of Article Eleven of the Original Indenture and this Article 3.

The Company shall determine any Applicable Premium and shall notify the Trustee thereof in writing at least two Business Days in advance of the payment date thereof. The Trustee shall have no responsibility for any calculation of any such amounts and may rely conclusively on the Company’s determinations thereof.

(b) Notwithstanding the provisions of clause (a) of this Section 3.02, at any time on and after January 1, 2023, the Company may on any one or more occasions redeem the Notes, in whole or in part, at the redemption price of 100% of the aggregate principal amount thereof, together with accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date).

Section 3.03 Mandatory Redemption.

Except as set forth under Sections 4.10 and 4.15 hereof, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders.

In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence an offer to all Holders to purchase Notes (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 “Settlement Date”), the Company shall purchase and pay for the principal amount of Notes required to be purchased pursuant to Section 4.10 hereof (the “Offer Amount”) or, if less than the Offer Amount has been tendered, all Notes validly tendered in response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the manner prescribed in the Notes.

Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, (or otherwise deliver in accordance with the applicable procedures of the Depositary) a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes 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 3.04 and Section 4.10 hereof and the length of time the Asset Sale Offer shall remain open, including the time and date the Asset Sale Offer will terminate (the “Termination Date”);

(b) the Offer Amount and the purchase price;

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

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

(f) that Holders electing to have a Note purchased pursuant to any Asset Sale Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Company or a Paying Agent at the address specified in the notice, before the Termination Date;

(g) that Holders shall be entitled to withdraw their election if the Company or the Paying Agent, as the case may be, receives, prior to the Termination Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(h) that, if the aggregate principal amount of Notes surrendered by Holders, and Pari Passu Indebtedness surrendered by holders or lenders, collectively, exceeds the amount the Company is required to repurchase, the Trustee shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate of the aggregate accreted value (if issued with original issue discount) or principal amount of tendered Notes and Pari Passu Indebtedness (provided that the selection of such Pari Passu Indebtedness shall be made pursuant to the terms of such Pari Passu Indebtedness) (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000 or any integral multiple of $1,000 in excess thereof will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero; and

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

If any of the Notes subject to an Asset Sale Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to repurchases.

Promptly after the Termination Date, the Company shall, to the extent lawful, accept for payment Notes or portions thereof tendered pursuant to the Asset Sale Offer in the aggregate principal amount required by Section 4.10 hereof, and prior to the Settlement Date it shall deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.04 and Section 4.10 hereof. On the Settlement Date, the Company or the Paying Agent, as the case may be, shall mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company shall issue a new Note, and the Trustee shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer on or before the Settlement Date.

(3) make any principal payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, any Indebtedness that is subordinated to the Notes or the Subsidiary Guarantees (other than Indebtedness of the Company owing to and held by any Guarantor or Indebtedness of a Guarantor owing to and held by the Company or any other Guarantor permitted under clause (6) of Section 4.09) prior to any scheduled repayment or scheduled maturity, except a payment, purchase, redemption, defeasance or other acquisition of any such Indebtedness in anticipation of satisfying a sinking fund obligation, principal installment or the Stated Maturity thereof, in each case, due within one year of the date of such payment, purchase, redemption, defeasance or other acquisition; or

(4) make any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted Payments”),

unless, at the time of and after giving effect to such Restricted Payment:

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;

(2) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the

beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 4.09; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after May 11, 2004 (excluding Restricted Payments permitted by clauses (2), (3), (4), (5). (6), (7) and (8) of the next succeeding paragraph), is less than the sum, without duplication, of:

(a) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from April 1, 2004 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

(b) 100% of the aggregate Net Cash Proceeds received by the Company (including the fair market value of any Additional Assets to the extent acquired in consideration of Equity Interests of the Company (other than Disqualified Stock)) since May 11, 2004 as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company), plus

(c) to the extent that any Restricted Investment that was made after May 11, 2004 is sold for cash or otherwise liquidated or repaid for cash, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment, plus

(d) to the extent that any Unrestricted Subsidiary of the Company is redesignated as a Restricted Subsidiary after May 11, 2004, the lesser of (i) the fair market value of the Company’s Investment in such Subsidiary as of the date of such redesignation or (ii) such fair market value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary.

The preceding provisions will not prohibit:

(1) the payment of any dividend or distribution or the consummation of any irrevocable redemption of debt that is subordinate to the Notes, within 60 days after the date of declaration of such dividend or the delivery of any irrevocable notice of redemption, as the case may be, if the dividend, distribution or redemption payment on the date of declaration or the date of the notice of redemption, as the case may be, would have complied with the provisions of this Indenture;

(2) the redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness of the Company or any Guarantor or of any Equity Interests of the Company in exchange for, or out of the Net Cash Proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock), with a sale being deemed substantially concurrent if such redemption, repurchase, retirement, defeasance or acquisition occurs not more than 120 days after such sale; provided that the amount of any such Net Cash Proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition will be excluded from clause (3)(b) of the preceding paragraph;

(3) the defeasance, redemption, repurchase, retirement or other acquisition of subordinated Indebtedness of the Company or any Guarantor with the Net Cash Proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness;

(4) the payment of any dividend or distribution by a Restricted Subsidiary of the Company to the holders of its Equity Interests on a pro rata basis;

(6) the acquisition of Equity Interests by the Company in connection with the exercise of stock options or stock appreciation rights or other equity-based awards by way of cashless exercise;

(7) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of subordinated Indebtedness of the Company or any Restricted Subsidiary (a) at a purchase price not greater than 101.0% of the principal amount thereof (plus accrued and unpaid interest) in the event of a Change of Control Triggering Event in accordance with provisions similar to Section 4.15 or (b) at a purchase price not greater than 100.0% of the principal amount thereof (plus accrued and unpaid interest) in accordance with provisions similar to Section 4.10; provided that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Company has made the Change of Control Offer or Asset Sale Offer, as applicable, as provided in such covenants with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Change of Control Offer or Asset Sale Offer;

(8) the payment of cash in lieu of fractional shares of Capital Stock in connection with any transaction otherwise permitted under this Section 4.07; or

(9) other Restricted Payments in an aggregate amount since May 11, 2004 not to exceed $50.0 million;

provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under the preceding clause (9), no Default or Event of Default shall have occurred and be continuing or would be caused thereby.

The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this Section 4.07 will be determined, in the case of amounts under $50.0 million, in good faith by an officer of the Company and, in the case of amounts of $50.0 million or more, by the Board of Directors of the Company, whose determination shall be evidenced by a Board Resolution. The amount of any Restricted Payment paid in cash shall be its face amount. Not later than the date of making any Restricted Payment (excluding any Restricted Payment described in the preceding clause (2), (3), (4), (5), (6), (7) or (8)) in excess of $50.0 million, the Company will 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. For purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in the preceding clauses (1) through (9), or is entitled to be made pursuant to the first paragraph of this Section 4.07, the Company will be permitted to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 4.07.

Section 4.08 Limitation on Dividend and Other Payment Restrictions Affecting Subsidiaries.

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

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries (it being understood that the priority of any preferred stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a restriction on the ability to pay dividends or make distributions on Capital Stock), or pay any Indebtedness or other obligations owed to the Company or any of its Restricted Subsidiaries;

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

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

However, the preceding restrictions of this Section 4.08 will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements governing Existing Indebtedness, Capital Stock and Credit Facilities as in effect on the Issue Date and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements; provided, that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such encumbrances and restrictions than those contained in the applicable agreements or instruments on the Issue Date as determined in good faith by the Company;

(2) this Indenture, the Notes, the Exchange Notes and the Subsidiary Guarantees;

(3) Applicable Law, rule, regulation, order, approval, license, permit or similar restriction;

(4) 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, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided, further, that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such encumbrances and restrictions than those contained in those agreements on the date of such acquisition as determined in good faith by the Company;

(5) customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices;

(6) Capital Lease Obligations or purchase money obligations, in each case for property acquired in the ordinary course of business that impose restrictions on that property of the nature described in clause (3) of the preceding paragraph;

(7) any agreement for the sale or other disposition of a Restricted Subsidiary of the Company that restricts distributions and/or transfers of properties and assets by that Restricted Subsidiary pending its sale or other disposition;

(8) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced as determined in good faith by the Company;

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

(10) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements, agreements respecting Permitted Business Investments and other similar agreements entered into (a) in the ordinary course of business or (b) with the Company’s approval by its Board of Directors, which limitation is applicable only to property or Capital Stock that are subject to such agreements;

(11) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers or suppliers under contracts entered into in the ordinary course of business;

(12) restrictions on the sale, lease or transfer of property or assets arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company and the Restricted Subsidiaries taken as a whole;

(13) Hedging Obligations permitted to be incurred under Section 4.09 hereof;

(14) with respect to any Restricted Subsidiary incorporated or organized outside the United States, any encumbrance or restriction contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was incurred if either (a) the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (b) the Company determines that any such encumbrance or restriction will not materially affect the Company’s ability to make principal or interest payments on the Notes, as determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive; and

(15) encumbrances or restrictions contained in agreements governing Indebtedness, Disqualified Stock, or preferred stock, as applicable, of the Company or any of its Restricted Subsidiaries permitted to be incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 4.09, provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness, Disqualified Stock or preferred stock, as the case may be, are not materially less favorable to the Company taken as a whole, as determined by the Board of Directors of the Company in good faith, than the provisions contained in the Credit Agreement and in this Indenture as in effect on the Issue Date.

Section 4.09 Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), neither the Company nor any Guarantor will issue any Disqualified Stock, and the Company will not permit any Non-Guarantor Subsidiary to issue any shares of preferred stock; provided, however, that the Company and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, and any Restricted Subsidiary may issue preferred stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Stock or preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.

The first paragraph of this Section 4.09 will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(1) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness (including letters of credit) under one or more Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum available amount thereunder) not to exceed an amount equal to the greater of (a) $3.0 billion or (b) 30.0% of ACNTA as of the date of such incurrence;

(2) the incurrence by the Company or any of its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes and the related Subsidiary Guarantees issued on the Issue Date and any Exchange Notes and the related Subsidiary Guarantees thereof;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in Oil and Gas Business of the Company or such Restricted Subsidiary, in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of (a) $100.0 million or (b) 1.0% of ACNTA as of the date of such incurrence at any time outstanding;

(5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness, or the issuance by the Company or any Restricted Subsidiary of Disqualified Stock or by any Restricted Subsidiary of preferred stock, in each case in exchange for, or the net proceeds of which are used to refund, refinance or replace Indebtedness (other than intercompany Indebtedness), Disqualified Stock or preferred stock that was permitted by this Indenture to be incurred or issued under the first paragraph of this Section 4.09 or clause (2) or (3) of this paragraph or this clause (5);

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

(a) if the Company is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, or if a Guarantor is the obligor on such Indebtedness and neither the Company nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Subsidiary Guarantee of such Guarantor; and

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the issuance by any Restricted Subsidiary to the Company or to any Restricted Subsidiary of shares of Disqualified Stock or preferred stock; provided, however, that:

(a) any subsequent issuance or transfer of Equity Interests that results in any such Disqualified Stock or preferred stock being held by a Person other than the Company or a Restricted Subsidiary of the Company, and

(b) any sale or other transfer of any such Disqualified Stock or preferred stock to a Person that is neither the Company nor a Restricted Subsidiary,

will be deemed, in each case, to constitute an issuance of such Disqualified Stock or preferred stock by such Restricted Subsidiary that was not permitted by this clause (7);

(8) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations;

(9) the guarantee by the Company or any of the Guarantors of Indebtedness of the Company or any Guarantor that was permitted to be incurred by another provision of this Section 4.09;

(10) the incurrence by the Company or any of its Restricted Subsidiaries of obligations relating to net gas balancing positions arising in the ordinary course of business and consistent with past practice;

(11) the incurrence by the Company’s Unrestricted Subsidiaries of Non-Recourse Debt, provided, however, that if any such Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such event will be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that was not permitted by this clause (11);

(12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance, surety and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of the Company and any of its Restricted Subsidiaries with respect to letters of credit supporting such obligations (in each case other than an obligation for money borrowed);

(13) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such disposition;

(14) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided, however, that such Indebtedness is promptly extinguished;

(15) Indebtedness arising in connection with endorsement of instruments for deposit in the ordinary course of business;

(16) Indebtedness owed on a short-term basis to banks and other financial institutions incurred in the ordinary course of business of the Company and any Restricted Subsidiary with such banks or financial institutions that arises in connection with ordinary banking arrangements to manage cash balances of the Company and any Restricted Subsidiary;

(17) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with a transaction meeting either one of the financial tests set forth in clause (4) under Section 5.01 hereof; and

(18) the incurrence or issuance by the Company or any of its Restricted Subsidiaries of additional Indebtedness, Disqualified Stock or preferred stock in an aggregate principal amount, or accreted value or liquidation preference, as applicable at any time outstanding, not to exceed the greater of (a) $250.0 million or (b) 2.5% of ACNTA as of the date of incurrence.

For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) or Disqualified Stock or preferred stock, as

applicable meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (18) above, or is entitled to be incurred pursuant to the first paragraph of this Section 4.09, the Company will be permitted to divide and classify (or later divide, classify, reclassify or re-divide in whole or in part in its sole discretion) such item of Indebtedness or Disqualified Stock or preferred stock, as applicable in any manner that complies with this Section 4.09, except that any Indebtedness under Credit Facilities on the Issue Date (after giving effect to the application of the proceeds from the offering of the Initial Notes contemplated by the offering memorandum relating to such offering) shall be considered incurred under the first paragraph of this Section 4.09. In addition, the principal amount of any Disqualified Stock or preferred stock of a Person shall be deemed to be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference of all obligations of such Person with respect to the redemption, repayment or other repurchase of any Disqualified Stock, or with respect to any Non-Guarantor Subsidiary, any preferred stock.

The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock and the payment of dividends on preferred stock in the form of additional shares of the same class of preferred stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred stock for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed exceeded solely as a result of fluctuations in exchange rates or currency values.

Section 4.10 Limitation on Asset Sales.

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

(1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of;

(2) the fair market value is determined by the Company’s Board of Directors and evidenced by a Board Resolution; and

(3) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this clause (3) of Section 4.10 only, each of the following will be deemed to be cash or Cash Equivalents:

(a) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet, of the Company or any Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a novation agreement that releases the Company or such Subsidiary from further liability;

(b) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Subsidiary into cash within 270 days of the receipt thereof, to the extent of the cash received in that conversion; and

(c) with respect to any Asset Sale of oil and natural gas properties where the Company or such Restricted Subsidiary retains an interest in such property, the aggregate costs and expenses of the Company or such Restricted Subsidiary related to the exploration, development, completion or production of such properties and activities related thereto which the transferee (or an Affiliate thereof) agrees to pay.

Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any such Restricted Subsidiary may apply those Net Proceeds at its option to any combination of the following:

(I) to prepay, repay, redeem or repurchase any Indebtedness of the Company or a Guarantor (other than intercompany Indebtedness, Capital Stock or Indebtedness that is subordinated to the Notes or the Subsidiary Guarantees) or any Indebtedness of a Restricted Subsidiary that is not a Guarantor (other than intercompany Indebtedness);

(II) to acquire all or substantially all of the properties or assets of one or more other Persons primarily engaged in the Oil and Gas Business, and, for this purpose, a division or line of business of a Person shall be treated as a separate Person;

(III) to acquire a majority of the Voting Stock of one or more other Persons primarily engaged in the Oil and Gas Business;

(IV) to make one or more capital expenditures; or

(V) to acquire other property or assets that are used or useful in the Oil and Gas Business.

Pending the final application of any Net Proceeds, the Company or any such Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph will constitute “Excess Proceeds.”

On the 361st day after the Asset Sale (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $50.0 million, the Company will make an Asset Sale Offer to all Holders of Notes, and to all holders of other Pari Passu Indebtedness containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other Pari Passu Indebtedness that may be purchased out of the Excess Proceeds,

pursuant to the terms in Section 3.04 hereof and this Section 4.10. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Settlement Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other Pari Passu Indebtedness tendered in such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate accreted value (if issued with original issue discount) or principal amount of tendered Notes and Pari Passu Indebtedness (provided that the selection of such Pari Passu Indebtedness shall be made pursuant to the terms of such Pari Passu Indebtedness) (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000 or any integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other Applicable Law to the extent applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.04 or this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions by virtue of such compliance.

Section 4.11 Limitation on Transactions with Affiliates.

The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an “Affiliate Transaction”) involving aggregate consideration in excess of $5.0 million, unless:

(1) the Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; and

(2) the Company delivers to the Trustee:

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million but less than or equal to $50.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11 and has been approved by the resolution of a majority of the disinterested members of the Board of Directors.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph of this Section 4.11:

(1) any employment, severance or consulting agreement or other compensation agreement, arrangement or plan or any amendment thereto, any issuance of Capital Stock (other than Disqualified Stock) or other payments, awards or grants in cash, Capital Stock (other than Disqualified Stock) or otherwise pursuant to, or the funding of, employment, severance or consulting agreements and other compensation agreements, arrangements and plans, options to purchase Capital Stock (other than Disqualified Stock) of the Company, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar employee benefits plans, in each case arising in the ordinary course of business of the Company or any of its Restricted Subsidiaries;

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

(3) transactions with a Person that is an Affiliate of the Company solely because the Company owns an Equity Interest in such Person, including, without limitation, any transaction with a joint venture or similar entity (other than an Unrestricted Subsidiary);

(4) payment of reasonable directors’ fees, consulting fees and other benefits to persons who are not otherwise Affiliates of the Company;

(5) provision of officers’ and directors’ indemnification and insurance in the ordinary course of business to the extent permitted by law;

(6) sales of Equity Interests (other than Disqualified Stock) to Affiliates of the Company;

(7) Permitted Investments and Restricted Payments that are permitted by Section 4.07 hereof;

(9) transactions with Unrestricted Subsidiaries, Affiliates, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in

each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are, in the aggregate (taking into account all the costs and benefits associated with such transactions) materially no less favorable to the Company or its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated person, in the good faith determination of the Company’s Board of Directors, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party; and

(10) transactions between the Company or any of its Restricted Subsidiaries and any Person, a director of which is also a director of the Company or any direct or indirect parent of the Company; provided, however, that such director abstains from voting as a director of the Company or such direct or indirect parent, as the case may be, on any matter involving such other Person.

For the avoidance of doubt, the creation, incurrence, assumption and existence of Liens (but not the foreclosure thereof) shall be governed by this Section 4.12 and not by Sections 4.10, 4.15 or 5.01.

Section 4.13 Additional Subsidiary Guarantees.

If the Company or any of its Restricted Subsidiaries acquires or creates another Material Domestic Subsidiary after the Issue Date, or if any Non-Guarantor Subsidiary either (a) becomes a borrower or guarantees any Indebtedness of the Company or another Restricted Subsidiary of the Company under the Credit Agreement or (b)(i) guarantees any other Capital Markets Indebtedness of the Company or any Restricted Subsidiary, or (ii) incurs any Capital Markets Indebtedness, then in each case that Subsidiary will become a Guarantor by executing a supplemental indenture substantially in the form of Exhibit B hereto and delivering it to the Trustee within 20 Business Days of the date on which it was acquired or created or guaranteed or incurred such Indebtedness of the Company, as the case may be, together with any Opinion of Counsel described in Section 903 of the Original Indenture.

Section 4.14 Corporate Existence.

Except as otherwise permitted pursuant to the terms hereof (including as permitted by Section 5.01 hereof), the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such

Section 4.15 Offer to Repurchase Upon Change of Control Triggering Event.

(1) Within 30 days following the occurrence of a Change of Control Triggering Event, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price (the “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, thereon to the date of settlement (the “Change of Control Settlement Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Settlement Date. Within 30 days following any Change of Control Triggering Event, the Company shall mail (or otherwise deliver in accordance with the applicable procedures of the Depositary) a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction that constitutes the Change of Control and stating:

(a) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes validly tendered and not withdrawn will be accepted for payment;

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

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

Purchase” on the reverse of the Notes completed and such customary documents as the Company may reasonably request, to the Paying Agent at the address specified in the notice prior to the termination of the Change of Control Offer on the Change of Control Purchase Date;

(g) that Holders will be entitled to withdraw their election if the Paying Agent receives, prior to the termination of the Change of Control Offer, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased; and

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

If any of the Notes subject to a Change of Control Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to repurchases. Notwithstanding the foregoing, the Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder and all Applicable Law to the extent those laws, regulations and orders are applicable in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations or any such other Applicable Law conflict with the provisions of this Section 4.15, the Company will comply with the applicable securities laws and regulations and all such other Applicable Law and will not be deemed to have breached its obligations under such provisions by virtue of such compliance.

(2) On the Change of Control Settlement Date, the Company shall, to the extent lawful, accept for payment all Notes or portions thereof (in minimum denominations of $2,000 or any integral $1,000 multiple in excess thereof) properly tendered pursuant to the Change of Control Offer.

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

On the Change of Control Settlement Date, the Paying Agent shall mail to each Holder properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary) and the Trustee shall authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes

The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date.

(c) The Change of Control provisions described above shall be applicable whether or nor any other provisions of this Indenture are applicable.

(d) [Intentionally Omitted.]

(e) The Company shall not be required to make a Change of Control Offer following a Change of Control Triggering Event if (1) a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption has been given pursuant to Section 3.02 hereof with respect to all outstanding Notes, unless and until there is a default in payment of the applicable Redemption Price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer by the Company or a third party may be made in advance of a Change of Control Triggering Event, and conditioned upon the occurrence of a Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control Triggering Event at the time the Change of Control Offer is made.

(3) In the event that Holders of Notes of not less than 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer and the Company purchases all of the Notes held by such holders, the Company will have the right, upon not less than 30 nor more than 60 days, prior notice given not more than 30 days following the purchase pursuant to the Xxxxx of Control Offer, to redeem all of the Notes that remain outstanding following such purchase at a purchase price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, if any, to the Change of Control Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Change of Control Settlement Date. Any such redemption shall be effected in accordance with Article Eleven of the Original Indenture, as modified by Section 3.01 hereof.

Section 4.16 No Inducements.

The Company shall not, and the Company shall not permit any of its Subsidiaries, either directly or indirectly, to pay (or cause to be paid) any consideration, whether by way of interest, fee or otherwise, to any Beneficial Owner or Holder of the Notes for or as an inducement to any consent to any waiver, amendment or supplement of any terms or provisions of this Indenture or the Notes, unless such consideration is offered to be paid (or agreed to be paid) to all Beneficial Owners and Holders which so consent in the time frame set forth in the solicitation documents relating to such consent.

Section 4.17 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of the Company may designate any Subsidiary (including any acquired or newly formed Subsidiary) of the Company to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary of the Company is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07 hereof or represent Permitted Investments, as determined by the Company. That designation shall only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

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

Section 4.18 Covenant Termination.

If at any time (a) the rating assigned to the Notes by both S&P and Xxxxx’x is an Investment Grade Rating and (b) no Default has occurred and is continuing under this Indenture (excluding, for the avoidance of doubt, any Default under one or more of the provisions listed below, provided that such Default did not exist immediately prior to the transaction or series of related transactions resulting in the applicable change in ratings), then upon delivery by the Company to the Trustee of an Officers’ Certificate to the foregoing effect, the Company and its Restricted Subsidiaries will no longer be subject to the following provisions of this Indenture: Sections 4.07, 4.08, 4.09, 4.10 or 4.11 or clause (d) of Section 5.01. The Company and its Restricted Subsidiaries will remain subject to all other provisions of this Indenture, including, without limitation, Sections 4.03, 4.12, 4.13, 4.17 and 5.01 other than clause (d) thereof).

(6) 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 is created after the Issue Date, if such default:

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

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

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $100.0 million or more; provided, that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 20 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 Notes shall be automatically rescinded unless such rescission would conflict with any judgment or decree of a court of competent jurisdiction;

(d) makes a general assignment for the benefit of its creditors, or

(e) admits in writing it generally is not paying its debts as they become due; or

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

(c) orders the liquidation of the Company, any Significant Subsidiary of the Company or any group of Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary;

Upon any such declaration, the Notes shall become due and payable immediately, together with all accrued and unpaid interest and premium, if any, thereon. Notwithstanding the preceding, if an Event of Default specified in clause (9) or (10) of Section 6.01 hereof occurs with respect to the Company, any Significant Subsidiary of the Company or any group of Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes shall become due and payable without further action or notice, together with all accrued and unpaid interest and premium, if any, thereon.

An Event of Default for the Notes shall not necessarily constitute an Event of Default for any other series of debt securities that may be issued under this Indenture in the future and vice versa.”

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

The provisions of Article Fifteen of the Original Indenture shall not apply to the Notes, and in lieu thereof the following provisions of this Article 8 shall apply to the Notes.

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may, at its option and at any time, exercise its rights under either Section 8.02 or 8.03 hereof with respect to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have discharged its obligations with respect to all outstanding Notes, and each Guarantor shall be deemed to have discharged its obligations with respect to its Subsidiary Guarantee, on the date the conditions set forth in Section 8.04 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 Notes, and each Guarantor shall be deemed to have paid and discharged its Subsidiary Guarantee (which in each case shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Fourth Supplemental Indenture and the Sections of the Original Indenture referred to in (a) and (b) below) and to have satisfied all its other obligations under such Notes or Subsidiary Guarantee 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 Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, and interest and premium, if any, on such Notes when such payments are due, (b) the Company’s obligations with respect to such Notes under Sections 304, 305, 306, 1002 and 1003 of the Original Indenture 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) the Legal Defeasance provisions of this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

If the Company exercises its Legal Defeasance option, each Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee and any security for the Notes (other than the trust) will be released.

Section 8.03 Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Article 4 hereof (other than those in Sections 4.01, 4.02, 4.06 and 4.14 hereof) and in clause (d) of Section 5.01 hereof on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and any Guarantor 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 with respect to the Notes under Section 501 of the Original Indenture (as amended by Section 6.01 of this Fourth Supplemental Indenture), but, except as specified above, the remainder of this Indenture and such Notes 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(5) through 6.01(7) of this Fourth Supplemental Indenture shall not constitute Events of Default with respect to the Notes.

If the Company exercises its Covenant Defeasance option, each Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee and any security for the Notes (other than the trust) will be released.

Section 8.04 Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance:

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

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders and Beneficial Owners of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

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

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

(v) 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 and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

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

(vii) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

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 pursuant to Section 8.04 or 8.08 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the 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 Notes 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 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 Notes.

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, Covenant Defeasance or Discharge, as the case may be.

Section 8.06 Repayment to Company.

Subject to applicable escheat and abandoned property laws, 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 or premium or interest on any Note and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a secured 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 will be repaid to the Company.

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 8.05 hereof, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.05 hereof; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Section 8.08 Discharge.

This Indenture shall be satisfied and discharged (a “Discharge”) and shall cease to be of further effect as to all Notes issued hereunder, upon the terms and conditions, and subject to the exceptions, set forth in Article Four of the Original Indenture.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

Section 901 of the Original Indenture is hereby amended to read in its entirety as follows with respect to the Notes:

“Notwithstanding Section 902 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Subsidiary Guarantees without the consent of any Holder of a Note:

(i) to cure any ambiguity, omission, defect or inconsistency;

(ii) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(iii) to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of Notes pursuant to Article 5 or Section 10.03 of this Fourth Supplemental Indenture;

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

(v) to secure the Notes or the Subsidiary Guarantees;

(vi) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture;

(vii) to add any additional Guarantor with respect to the Notes or to evidence the release of any Guarantor from its Subsidiary Guarantee in accordance with Article 10 of this Fourth Supplemental Indenture;

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

(ix) to evidence or provide for the acceptance of appointment under this Indenture of a successor Trustee;

(x) to provide for the issuance of Exchange Notes or private exchange notes (which shall be identical to Exchange Notes except that they will not be freely transferable) and which shall be treated, together with any outstanding notes, as a single class of securities;

(xi) to conform the text of this Indenture, the Notes or the Subsidiary Guarantees to any provision of the “Description of notes” in the offering memorandum relating to the offering of the Initial Notes; and

(xii) make any amendment to the provisions of this Indenture relating to the transfer and legending of Notes as permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of the Notes, Exchange Notes or, if incurred in compliance with this Indenture, Additional Notes; provided, however, that (A) compliance with this Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any applicable securities law and (B) such amendment does not materially and adversely affect the rights of Holders to transfer Notes.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the Opinion of Counsel described in Section 9.03 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such 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.

It shall not be necessary for the consent of the Holders of Notes under this Section 9.01 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

Section 9.02 With Consent of Holders of Notes.

Section 902 of the Original Indenture is hereby amended to read in its entirety as follows with respect to the Notes:

“Except as provided above in Section 901 and below in this Section 902, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Subsidiary Guarantees 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 tender offer or exchange offer for, Notes), and, subject to Sections 508 and 513 hereof, any existing Default or Event of Default with respect to the Notes or compliance with any provision of this Indenture, the Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for Notes).

Upon the request of the Company accompanied by a resolution of its Board of Directors 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 Notes as aforesaid, and upon receipt by the Trustee of the Opinion of Counsel described in Section 903 hereof, the Trustee shall join with the Company and the 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 Notes under this Section 902 to approve the particular form of any proposed amendment, supplement 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 Notes 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. Subject to Sections 508 and 513 hereof and to the last paragraph of this Section 902, the Holders of a majority in principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder):

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

(b) reduce the principal of or change the Stated Maturity of any Note or reduce the premium payable upon the redemption of any Note pursuant to Section 3.02, change the time at which any Note may be redeemed pursuant to Section 3.02 or make any change relative to the Company’s obligation to purchase the Notes as a result of a Change of Control Triggering Event or an Asset Sale after (but not before) the occurrence of the applicable Change of Control Triggering Event or Asset Sale;

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

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

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

(g) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 3.04, 4.10 and 4.15 of this Fourth Supplemental Indenture);

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

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

Section 9.03 Revocation and Effect of Consents.

A consent to any amendment, supplement or waiver under this Indenture by any Holder given in connection with a purchase, tender or exchange of such Holder’s Notes shall not be rendered invalid by such purchase, tender or exchange.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the 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 a record date 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 consent to such amendment or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date except to the extent that the requisite number of consents to the amendment, supplement or waiver have been obtained within such 90-day period or as set forth in the next paragraph of this Section 9.03.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (a) through (i) of Section 902 of this Indenture, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

ARTICLE 10

GUARANTEES OF NOTES

The Notes shall have the benefit of Subsidiary Guarantees. The provisions of Article Thirteen of the Original Indenture shall not apply to the Notes, and in lieu thereof the following provisions of this Article 10 shall apply to the Notes.

Section 10.01 Subsidiary Guarantees.

Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Fourth Supplemental Indenture or this Indenture, the Notes held thereby and the Obligations of the Company hereunder and thereunder, that: (a) the principal of and premium, if any, and

interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise, and interest on the overdue principal of and premium, if any, and (to the extent permitted by law) interest on the Notes, and all other payment Obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full and 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 Notes or any of such other Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise. Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. An Event of Default with respect to the Notes under this Indenture shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the Obligations of the Company.

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Fourth Supplemental Indenture 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 (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, 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 covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Obligations contained in the Notes and this Indenture.

If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any Custodian, Trustee or other similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to, and hereby waives, any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby.

Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Five of the Original Indenture for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article Five of the Original Indenture, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

Section 10.02 Notation of Subsidiary Guarantees.

The Subsidiary Guarantees shall be evidenced by the execution and delivery of this Fourth Supplemental Indenture or a supplement to this Indenture and no notation of any Subsidiary Guarantee need be endorsed on any Note, notwithstanding any contrary provision of the Original Indenture.

Section 10.03 Guarantors May Consolidate, Etc., on Certain Terms.

(a) A Guarantor shall not consolidate or merge with or into another Person (whether or not the Guarantor is the surviving entity), 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 (other than the Company or another Guarantor), unless, (i) either (1) the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) unconditionally assumes all the obligations of such Guarantor, pursuant to a supplemental indenture, substantially in the form of Exhibit B hereto, under the Notes, this Indenture and its Subsidiary Guarantee on terms set forth therein, or (2) the Net Proceeds of such sale or other disposition are applied in accordance with the provisions of Section 4.10 hereof, and (ii) immediately after giving effect to such transaction, no Default or Event of Default exists.

(b) In the case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and substantially in the form of Exhibit B hereto, of the Subsidiary Guarantee and the due and punctual performance of all of the covenants of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Section 10.04 Releases of Subsidiary Guarantees.

The Subsidiary Guarantee of a Guarantor shall be released:

(1) in connection with any sale or other disposition of all or substantially all of the properties or assets of such Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company, if the sale or other disposition complies with Section 4.10 hereof; provided that (i) all Subsidiary Guarantees and other obligations of such Guarantor in respect of all other Indebtedness of the Company and its Restricted Subsidiaries terminate upon consummation of such transaction and (ii) any Investment of the Company or any other Subsidiary of the Company (other than any Subsidiary of such Guarantor) in such Guarantor or any Subsidiary of such Guarantor in the form of an Obligation or preferred stock is repaid, satisfied, released and discharged in full upon such release;

(2) in connection with any sale or other disposition of all of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company, if the sale or other disposition complies with Section 4.10 hereof; provided that (i) all Subsidiary Guarantees and other obligations of

such Guarantor in respect of all other Indebtedness of the Company and its Restricted Subsidiaries terminate upon consummation of such transaction and (ii) any Investment of the Company or any other Subsidiary of the Company (other than any Subsidiary of such Guarantor) in such Guarantor or any Subsidiary of such Guarantor in the form of an Obligation or preferred stock is repaid, satisfied, released and discharged in full upon such release; or

(3) in the case of any Restricted Subsidiary which after the Issue Date is required to guarantee the Notes pursuant to Section 4.13 upon the release or discharge in full from its obligations as a borrower or guarantor (as the case may be) under the Credit Agreement and any Capital Markets Indebtedness which resulted, or would result, in such Restricted Subsidiary’s obligation to guarantee the Notes pursuant to Section 4.13 (including by reason of the termination of the Credit Agreement or such Capital Markets Indebtedness but excluding, if such Restricted Subsidiary was a guarantor under the Credit Agreement or such other Capital Markets Indebtedness, a release or discharge as a result of repayment under its guarantee thereof); so long as such Restricted Subsidiary does not thereafter become a borrower or guarantor under the Credit Agreement or incur or guarantee Capital Markets Indebtedness which would result in such Restricted Subsidiary’s obligation to guarantee the Notes pursuant to Section 4.13 without also guaranteeing the Notes; or

(4) if the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture; or

(5) upon Legal Defeasance or Covenant Defeasance or Discharge in accordance with Article 8 hereof.

Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that any of the foregoing clauses (1) – (5) has occurred, the Trustee shall execute any documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of, premium, if any, and interest on the Notes and for the other obligations of such Guarantor under this Indenture as provided in this Article 10.

Section 10.05 Limitation on Guarantor Liability.

The obligations of each Guarantor under its Subsidiary Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

Section 10.06 “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 this Article 10 shall in each 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 this Article 10 in place of the Trustee.

ARTICLE 11

Section 11.04 Force Majeure.

In no event shall the Trustee be responsible or liable, nor shall the Company be responsible or liable to the Trustee, for any failure or delay in the performance of its obligations

hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, and nuclear or natural catastrophes or acts of God; it being understood that the Trustee or the Company, as the case may be, shall use reasonable efforts which are consistent with accepted practices to resume performance as soon as practicable under the circumstances; provided that the foregoing limitations shall not apply to any obligations of Company or the Guarantors under the Notes.

The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as hereinafter provided. Additional Notes or other Notes, in each case that are not Transfer Restricted Securities, shall be issued in global form (with the global Notes legend set forth in Annex A) or in certificated form as provided in this Indenture. Notes issued in global form and Restricted Global Notes are sometimes referred to in this Appendix as “Global Notes.” The Global Notes are “Global Securities” within the meaning of this Indenture, and shall be subject to the further provisions of this Indenture with respect thereto.

(b) Book-Entry Provisions. This Section 2.01(b) shall apply only to a Global Note deposited with or on behalf of the Depositary. The Company shall execute and the Trustee shall, in accordance with this Section 2.01(b) and this Indenture, authenticate and deliver initially one or more Global Notes that (a) shall be registered in the name of the Depositary for such Global Note or Global Notes or the nominee of such Depositary and (b) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instructions or held by the Trustee as custodian for the Depositary. If such Global Notes are Restricted Global Notes, then separate Global Notes shall be issued to represent Rule 144A Notes and Regulation S Notes so long as required by law or the Depositary.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Note, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company

or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Note.

Until the 40th day after the later of the commencement of the offering of any Initial Notes and the original issue date of such Initial Notes (such period, the “Distribution Compliance Period”), a beneficial interest in a Restricted Global Note representing Regulation S Notes may be transferred to a Person who takes delivery in the form of an interest in a Restricted Global Note representing Rule 144A Notes only if the transferor first delivers to the Trustee a written certificate (in the form provided in the form of Note in Annex A) to the effect that such transfer is being made to a Person who the transferor reasonably believes is purchasing for its own account or accounts as to which it exercises sole investment discretion and that such Person is a QIB, in each case in a transaction meeting the requirements of Rule 144A and in accordance with any applicable securities laws of any state of the United States or any other jurisdiction. After the expiration of the Distribution Compliance Period, such certification requirements shall not apply to such transfers of beneficial interests in a Restricted Global Note representing Regulation S Notes.

Beneficial interests in a Restricted Global Note representing Rule 144A Notes may be transferred to a Person who takes delivery in the form of an interest in a Restricted Global Note representing Regulation S Notes, whether before or after the expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided in the form of Note in Annex A) to the effect that such transfer is being made in accordance with Rule 904 of Regulation S or Rule 144 (if available).

(c) Certificated Notes. Except as provided in this Indenture, owners of beneficial interests in Restricted Global Notes shall not be entitled to receive physical delivery of certificated Notes. Certificated Notes shall not be exchangeable for beneficial interests in Global Notes.

A transferor of a beneficial interest in a Global Note shall deliver to the Registrar a written order given in accordance with the Depositary’s procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the Global Note. The Registrar shall, in accordance with such instructions instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the beneficial interest in the Global Note being transferred.

(2) Notwithstanding any other provisions of this Appendix, a Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

(3) In the event that a Restricted Global Note is exchanged for Notes in certificated form pursuant to this Indenture, prior to the effectiveness of a Shelf Registration Statement with respect to such Notes, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.03 (including the certification requirements set forth on the reverse of the Initial Notes intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Company.

redemption, or otherwise; (iii) failure by the Company to comply with the provisions of Section 5.01 of the Fourth Supplemental Indenture or to consummate a purchase of Notes when required pursuant to Section 4.10 or 4.15 of the Fourth Supplemental Indenture; (iv) failure by the Company to comply for 30 days after notice by the Trustee or Holders of 25% of the outstanding principal amount of the Notes with Sections 4.07 and 4.09 of the Fourth Supplemental Indenture or, except in the case of a failure to purchase Notes when required described above in clause (iii), Section 4.10 and 4.15 of the Fourth Supplemental Indenture; (v) failure by the Company or a Guarantor for 60 days (or 180 days in the case of Reporting Failure) after notice to comply with any of its other agreements in the Indenture or the Notes; (vi) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists or is created after the Issue Date, if such default (a) is caused by a failure to pay principal of, or premium or interest, if any, on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness (a “Payment Default”) or (b) results in the acceleration of such Indebtedness prior to its Stated Maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $100.0 million or more; provided, that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 20 days from the continuation of such default beyond any applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default under the Indenture and any consequential acceleration of the Notes shall be automatically rescinded unless such rescission would conflict with any judgment or decree of a court of competent jurisdiction; (vii) failure by the Company or any of its Significant Subsidiaries to pay final judgments aggregating in excess of $100.0 million, which judgments are not paid, discharged or stayed (including a stay pending appeal) for a period of 60 days after the date of such final judgment (or, if later, the date when payment is due pursuant to such judgment); (viii) except as permitted by the Indenture, any Subsidiary Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee (other than by reason of release of a Guarantor from its Subsidiary Guarantee in accordance with the terms of the Indenture); and (ix) certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary as specified in Section 501(8) or 501(9) of the Indenture. If any Event of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes, by notice to the Company and the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the preceding, in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary described in Section 6.01(9) or (10) of the Fourth Supplemental Indenture), all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power conferred on it. The Trustee may withhold from Holders notice of any continuing Default or Event of Default with respect to the Notes (except a Default or Event of Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in principal amount of the

A - 9

Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any past Default or Event of Default with respect to the Notes and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of or premium, if any, or interest on the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and, so long as any Notes are outstanding, the Company is required upon becoming aware of any Default or Event of Default with respect to the Notes, to deliver to the Trustee a statement specifying such Default or Event of Default.

13. Defeasance and Discharge. The Notes are subject to defeasance and discharge upon the terms and conditions specified in the Indenture.

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

15. Authentication. This Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee or an authenticating agent.

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).

17. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers and corresponding ISIN numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

18. Governing Law. THE INDENTURE AND THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

19. Successor Entity. In the event a successor assumes all the obligations of the Company under the Notes and the Indenture, pursuant to the terms thereof, the Company will be released from all such obligations.
