     WHEREAS, the Company desires to provide for the issuance of a new series of Securities to be designated as the “6 5/8% Senior Subordinated Notes due 2014” (the “6 5/8% Notes”), and to set forth the terms that will be applicable thereto;

     WHEREAS, all action on the part of the Company necessary to authorize the issuance of the 6 5/8% Notes under the Original Indenture and this Second Supplemental Indenture (the Original Indenture, as amended and supplemented by this Second Supplemental Indenture, being hereinafter called the “Indenture”) has been duly taken; and

     WHEREAS, all acts and things necessary to make the 6 5/8% Notes, when executed by the Company and authenticated and delivered by the Trustee as provided in the Original Indenture, the legal, valid and binding obligations of the Company, and to constitute these presents a valid and binding supplemental indenture according to its terms binding on the Company, have been done and performed, and the execution of this Second Supplemental Indenture and the creation and issuance under the Indenture of the 6 5/8% Notes have in all respects been duly authorized, and the Company in the exercise of the legal right and power vested in it, executes this Second Supplemental Indenture and proposes to create, execute, issue and deliver the 6 5/8% Notes.

NOW, THEREFORE, THIS SECOND SUPPLEMENTAL INDENTURE WITNESSETH:

     That, in order to establish the designation, form, terms and provisions of, and to authorize the authentication and delivery of the 6 5/8% Notes, and in consideration of the acceptance of the 6 5/8% Notes 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:

1

     SECTION 1. Creation of 6 5/8% Notes.

          (a) Pursuant to Sections 201 and 301 of the Original Indenture, there is hereby created a new series of Securities designated as the “6 5/8% Senior Subordinated Notes due 2014” (which are hereinafter referred to as the “6 5/8% Notes” for purposes of this Second Supplemental Indenture).

          (b) The 6 5/8% Notes shall be issued initially in the form of one or more Global Securities substantially in the form set forth on Exhibit A hereto, duly executed by the Company and authenticated by the Trustee as provided in the Indenture. The terms of the 6 5/8% Notes set forth on Exhibit A hereto are incorporated by reference herein as if set forth herein in their entirety. The Notes constituting Transfer Restricted Securities will be sold by the Initial Purchasers thereof only to QIBs in reliance on Rule 144A. Pursuant to the terms of a Registration Rights Agreement, upon consummation of the Exchange Offer contemplated thereby, the 6 5/8% Notes constituting Transfer Restricted Securities will be exchanged by the Holders for Exchange Notes to be issued by the Company in accordance with this Section 1 and Section 3 hereof.

          (c) The Trustee shall authenticate and deliver 6 5/8% Notes for original issue on the Issue Date in an aggregate principal amount of $325,000,000 upon a Company Order for the authentication and delivery of Notes, without any further action by the Company, with Notes that are resold in reliance upon Rule 144A and Regulation S being represented by separate Global Securities, which are referred to in this Second Supplemental Indenture as the “Rule 144A Global Security” and the “Regulation S Global Security,” respectively. Subject to its compliance with Section 1010 of the Indenture, if then applicable, the Company may, from time to time, issue for sale to one or more Initial Purchasers an unlimited amount of additional 6 5/8% Notes (“Additional 6 5/8% Notes”) under the Indenture, which shall be issued in the same form as the 6 5/8% Notes issued on the Issue Date and which shall have identical terms as the 6 5/8% Notes issued on the Issue Date other than with respect to the issue date, issue price and date of first payment of interest; provided, however, that no Additional Notes may be issued at a price that would cause such Additional Notes to have “original issue discount” within the meaning of the Code. The Company Order delivered by the Company to the Trustee pursuant to Section 303 of the Original Indenture for the authentication and delivery of any Additional 6 5/8% Notes shall specify whether or not such Additional 6 5/8% Notes shall be Transfer Restricted Securities. The 6 5/8% Notes issued on the Issue Date and any Additional 6 5/8% Notes subsequently issued, together with any Exchange Notes issued in exchange therefor pursuant to an Exchange Offer, shall be treated as a single series for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase.

          (d) If the Company issues additional Transfer Restricted Securities prior to the completion of an Exchange Offer, the period of the resale restrictions applicable to any Transfer Restricted Securities previously offered and sold in reliance on Rule 144A will be automatically extended to the last day of the period of any resale restrictions imposed on any such additional Transfer Restricted Securities.

          (e) At all times while the Notes are outstanding, the Company shall maintain a Place of Payment for the Notes in The City of New York, which Place of Payment shall be

2

initially the office of the Trustee located at 4 New York Plaza, 15th Floor, New York, New York.

          (f) The 6 5/8% Notes shall be defeasible pursuant to both Sections 1302 and 1303.

          (g) Additional Interest shall be payable with respect to the 6 5/8% Notes issued on the Issue Date in accordance with the related Registration Rights Agreement, a form of which is attached to this Second Supplemental Indenture as Appendix A.

     “Consolidated Coverage Ratio” as of any date of determination means the ratio of (x) the aggregate amount of EBITDA for the period of the most recent four consecutive fiscal quarters for which financial information of the Company has been made publicly available prior to the date of such determination to (y) Consolidated Interest Expense for such four fiscal quarters; provided, however, that:

     (1) if the Company or any Restricted Subsidiary has Incurred any Indebtedness since the beginning of such period that remains outstanding or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, or both, then EBITDA and Consolidated Interest Expense for such period shall be calculated after giving effect on a pro forma basis to such Indebtedness and the use of proceeds thereof as if such Indebtedness had been Incurred on the first day of such period and such proceeds had been applied as of such date;

     (2) if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged on the date of the transaction giving rise to the need to calculate the Consolidated Coverage Ratio, then EBITDA and Consolidated Interest Expense for such period shall be calculated on a pro forma basis as if such discharge had occurred on the first day of such period and as if the Company or such Restricted Subsidiary had not earned the interest income actually earned (if any) during such period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness;

     (3) if, since the beginning of such period, the Company or any Restricted Subsidiary shall have made any Asset Disposition, then EBITDA for such period shall be reduced by an amount equal to EBITDA (if positive) directly attributable to the assets which were the subject of such Asset Disposition for such period, or increased by an amount equal to EBITDA (if negative), directly attributable thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

     (4) if, since the beginning of such period, the Company or any Restricted Subsidiary (by merger or otherwise) shall have made an Investment in any Restricted

9

     (5) if, since the beginning of such period, any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) shall have made any Asset Disposition, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (3) or (4) above if made by the Company or a Restricted Subsidiary during such period, then EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition had occurred on the first day of such period.

     For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof).

     The Consolidated Interest Expense attributable to interest on any Indebtedness under a revolving credit facility, the outstanding principal balance of which is required to be computed on a pro forma basis in accordance with the foregoing, shall be computed based upon the average daily balance of such Indebtedness during the applicable period; provided, however, that such average daily balance shall take into account the amount of any repayment of Indebtedness under such revolving credit facility during the applicable period to the extent such repayment permanently reduced the commitments or amounts available to be borrowed under such facility.

     “Consolidated Interest Expense” means, for any period, the total interest expense of the Company and its consolidated Restricted Subsidiaries, plus, to the extent not included in such total interest expense, and to the extent incurred by the Company or its Restricted Subsidiaries, without duplication:

     (2) amortization of debt discount and debt issuance cost;

     (5) commissions, discounts and other fees and charges owed with respect to letters of credit and bankers’ acceptance financing;

     (6) net payments pursuant to Interest Rate Agreements;

     (7) Preferred Stock dividends in respect of all Preferred Stock held by Persons other than the Company or a Wholly Owned Subsidiary (other than dividends payable solely in Capital Stock (other than Disqualified Stock) of the Company);

     (8) interest incurred in connection with Investments in discontinued operations;

     (10) the cash contributions to any employee stock ownership plan or similar trust to the extent such contributions are used by such plan or trust to pay interest or fees to any Person (other than the Company) in connection with Indebtedness Incurred by such plan or trust;

minus, to the extent included above, write-off of deferred financing costs and interest attributable to Dollar-Denominated Production Payments.

     “Consolidated Net Income” means, for any period, the net income of the Company and its consolidated Subsidiaries; provided, however, that there shall not be included in such Consolidated Net Income:

     (2) solely for purposes of determining the aggregate amount available for Restricted Payments under Section 1011(a)(3), any net income (or loss) of any Person acquired by the Company or a Subsidiary in a pooling of interests transaction for any period prior to the date of such acquisition;

11

     (3) any net income of any Restricted Subsidiary if such Restricted Subsidiary is subject to restrictions, directly or indirectly, on the payment of dividends or the making of distributions by such Restricted Subsidiary, directly or indirectly, to the Company, except that:

     (B) the Company’s equity in a net loss of any such Restricted Subsidiary for such period shall be included in determining such Consolidated Net Income;

     (4) any gain or loss, together with any related provision for taxes on such gain or loss and all related fees and expenses, realized in connection with (A) the sale or other disposition of any assets of the Company, its consolidated Subsidiaries or any other Person (including pursuant to any Sale/Leaseback Transaction) which is not sold or otherwise disposed of in the ordinary course of business and (B) the disposition of any securities of any Person or the extinguishment of any Indebtedness of the Company or any of its Subsidiaries;

Section 902. Supplemental Indentures With Consent of Holders.

     With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of each series affected by such supplemental indenture (including consents obtained in connection with a tender or exchange offer for the 6 5/8% Notes), by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding 6 5/8% Note affected thereby:

     (B) second, to the extent of the balance of such Net Available Cash after application in accordance with clause (A), to the extent the Company so elects, to acquire Additional Assets or make capital expenditures in the Oil and Gas Business within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; and

     (C) third, to the extent of the balance of such Net Available Cash after application in accordance with clauses (A) and (B), to make an offer to the Holders of the 6 5/8% Notes (and to holders of other Senior Subordinated Indebtedness of the Company designated by the Company) to purchase 6 5/8% Notes (and such other Senior Subordinated Indebtedness of the Company) pursuant to and subject to the conditions of this Section 1014;

provided, however, that in connection with any prepayment, repayment, purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness pursuant to clause (A) or (C) of this Section 1014(a)(3), the Company or such Restricted Subsidiary shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid or purchased.

51

     Notwithstanding the foregoing provisions of this Section 1014, the Company and the Restricted Subsidiaries shall not be required to apply any Net Available Cash in accordance with this Section 1014 except to the extent that the aggregate Net Available Cash from all Asset Dispositions which is not applied in accordance with this Section 1014(a) exceeds $20 million. Pending application of Net Available Cash pursuant to this Section 1014(a), such Net Available Cash shall be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit indebtedness.

     For the purposes of clause (a)(2) of this Section 1014, the following are deemed to be cash or cash equivalents: (1) the release of, pursuant to a novation or other agreement, or the discharge of, the Company or such Restricted Subsidiary from all liability on Indebtedness in connection with such Asset Disposition; and (2) securities received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or such Restricted Subsidiary into cash within 120 days of their receipt.

     Notwithstanding the foregoing, the 75% limitation referred to in paragraph (a)(2) of this Section 1014 shall be deemed satisfied with respect to any Asset Disposition in which the cash or cash equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Disposition complied with the aforementioned 75% limitation.

     The requirement of Section 1014(a)(3)(B) shall be deemed satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to therein is entered into by the Company or its Restricted Subsidiary within the time period specified in such clause and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

     (b) In the event of an Asset Disposition that requires the purchase of 6 5/8% Notes (and other Senior Subordinated Indebtedness of the Company) pursuant to Section 1014(a)(3)(C), the Company shall make such offer to purchase 6 5/8% Notes (the “Offer”) on or before the 366th day after the later of the date of such Asset Disposition or the receipt of such Net Available Cash, and will purchase 6 5/8% Notes tendered pursuant to the Offer by the Company for the 6 5/8% Notes (and such other Senior Subordinated Indebtedness of the Company) at a purchase price of 100% of their principal amount (or, in the event such other Senior Subordinated Indebtedness of the Company was issued with significant original issue discount, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest (or, in respect of such other Senior Subordinated Indebtedness of the Company, such lesser price, if any, as may be provided for by the terms of such Senior Subordinated Indebtedness of the Company) in accordance with the procedures (including prorating in the event of oversubscription) set forth in this Indenture. If the aggregate purchase price of 6 5/8% Notes and any other Senior Subordinated Indebtedness tendered exceeds the Net Available Cash allotted to their purchase, the Company shall select the 6 5/8% Notes and other Senior Subordinated Indebtedness to be purchased on a pro rata basis but in round denominations, which in the case of the 6 5/8% Notes shall be denominations of $1,000 principal amount or multiples thereof. The Company shall not be required to make such an Offer to purchase 6 5/8% Notes (and other Senior Subordinated Indebtedness of the Company) pursuant

52

to this Section 1014 if the Net Available Cash available therefor is less than $20 million (which lesser amount shall be carried forward for purposes of determining whether such an Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition).

     (c) (1) Promptly, and in any event within 10 days after the Company becomes obligated to make an Offer, the Company shall deliver to the Trustee and send, by first-class mail to each Holder, a written notice stating that the Holder may elect to have its 6 5/8% Notes purchased by the Company either in whole or in part (subject to prorating as described in Section 1014(b) in the event the Offer is oversubscribed) in integral multiples of $1,000 of principal amount, at the applicable purchase price. The notice shall specify a purchase date not less than 30 days nor more than 60 days after the date of such notice (the “Purchase Date”) and shall contain such information concerning the business of the Company which the Company in good faith believes will enable such Holders to make an informed decision and all instructions and materials necessary to tender 6 5/8% Notes pursuant to the Offer, together with the information contained in clause (3).

     (2) Not later than the date upon which written notice of an Offer is delivered to the Trustee as provided above, the Company shall deliver to the Trustee an Officers’ Certificate as to (A) the amount of the Offer (the “Offer Amount”), including information as to any other Senior Subordinated Indebtedness included in the Offer, (B) the allocation of the Net Available Cash from the Asset Dispositions pursuant to which such Offer is being made and (C) the compliance of such allocation with the provisions of Section 1014(a) and (b). On or before 11:00 a.m., New York City time, on the Purchase Date, the Company shall irrevocably deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) immediately available funds in an amount equal to the Offer Amount to be held for payment in accordance with the provisions of this Section. If the Offer includes other Senior Subordinated Indebtedness, the deposit described in the preceding sentence may be made with any other paying agent pursuant to arrangements satisfactory to the Trustee. Upon the expiration of the period for which the Offer remains open (the “Offer Period”), the Company shall deliver to the Trustee for cancellation the 6 5/8% Notes or portions thereof which have been properly tendered to and are to be accepted by the Company. The Trustee shall, on the Purchase Date, mail or deliver payment (or cause the delivery of payment) to each tendering Holder in the amount of the purchase price. In the event that the aggregate purchase price of the 6 5/8% Notes delivered by the Company to the Trustee is less than the Offer Amount applicable to the 6 5/8% Notes, the Trustee shall deliver the excess to the Company immediately after the expiration of the Offer Period. Upon completion of an Offer, Net Available Cash shall be deemed to be reduced by the Offer Amount.

     (3) Holders electing to have an 6 5/8% Notes purchased shall be required to surrender the 6 5/8% Note, with the form “Option of Holder to Elect Purchase” on the reverse duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Purchase Date. Holders shall be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the Purchase Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the 6 5/8% Notes which was delivered for purchase by the

53

Holder and a statement that such Holder is withdrawing its election to have such 6 5/8% Notes purchased. Holders whose Securities are purchased only in part shall be issued new 6 5/8% Notes equal in principal amount to the unpurchased portion of the 6 5/8% Notes surrendered.

     (4) At the time the Company delivers 6 5/8% Notes to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officers’ Certificate stating that such 6 5/8% Notes are to be accepted by the Company pursuant to and in accordance with the terms of this Section. An 6 5/8% Note shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder.

     (d) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of 6 5/8% Notes pursuant to this Section. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section by virtue of its compliance with such securities laws or regulations.

Section 1015. Limitation on Affiliate Transactions.

     (a) The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with, or for the benefit of, any Affiliate of the Company (an “Affiliate Transaction”) unless:

     (1) the terms of the Affiliate Transaction are no less favorable to the Company or such Restricted Subsidiary than those that could reasonably be expected to be obtained at the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate;

     (2) if such Affiliate Transaction involves an amount in excess of $15 million, the terms of the Affiliate Transaction are set forth in writing and a majority of the non-employee directors of the Company disinterested with respect to such Affiliate Transaction shall have determined in good faith that the criteria set forth in clause (1) are satisfied and shall have approved the relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors; and

     (3) if such Affiliate Transaction involves an amount in excess of $30 million, the Board of Directors shall have received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and its Restricted Subsidiaries or is not less favorable to the Company and its Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was not an Affiliate.

54

     (b) The provisions of Section 1015(a) shall not prohibit:

     (1) any Investment or other Restricted Payment, in each case not prohibited to be made pursuant to Section 1011;

     (2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans and other benefit plans approved by the Board of Directors;

     (3) loans or advances to officers, directors and employees who are Affiliates in the ordinary course of business of the Company or its Restricted Subsidiaries, but in any event not to exceed $3.0 million in the aggregate outstanding at any one time;

     (4) any transaction between or among the Company, a Restricted Subsidiary or joint venture or similar Person that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in or otherwise controls such Restricted Subsidiary, joint venture or similar Person;

     (5) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Company;

     (6) reasonable fees and reasonable compensation paid to, and indemnity and similar arrangements provided on behalf of, officers, directors and employees of the Company or any Restricted Subsidiary as determined in good faith by the Board of Directors or the Company’s senior management; and

     (7) any agreement as in effect on the Issue Date and described in the Offering Memorandum pursuant to which the 6 5/8% Notes were offered and sold, or any renewals or extensions of any such agreement (so long as such renewals or extensions are not less favorable to the Company or the Restricted Subsidiaries) and the transactions evidenced thereby.

Section 1016. Change of Control.

     (a) Upon the occurrence of a Change of Control, then unless the Company shall have exercised its right to redeem all the 6 5/8% Notes, each Holder shall have the right to require that the Company repurchase such Holder’s 6 5/8% Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of the purchase plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date), in accordance with the terms contemplated in Section 1016(b).

     (b) Unless the Company has exercised its right to redeem all the 6 5/8% Notes and shall have delivered an irrevocable notice of redemption to the Trustee, then within 30 days following any Change of Control, the Company shall mail a notice to each Holder with a copy to the Trustee (the “Change of Control Offer”) stating:

55

     (1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s 6 5/8% Notes at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest on the relevant Interest Payment Date);

     (2) the circumstances and relevant facts regarding such Change of Control (including information with respect to pro forma historical income, cash flow and capitalization, in each case after giving effect to such Change of Control);

     (3) the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and

     (4) the instructions, as determined by the Company, consistent with this Section 1016, that a Holder must follow in order to have its 6 5/8% Notes purchased.

     In the event that at the time of a Change of Control the terms of any Senior Indebtedness of the Company (including the Revolving Credit Facility) restrict or prohibit the repurchase of 6 5/8% Notes following such Change of Control pursuant to this Section 1016, then prior to the mailing of such notice to Holders but in any event within 30 days following any Change of Control, the Company shall (1) repay in full all such Senior Indebtedness or (2) obtain the requisite consents under the agreements governing such Senior Indebtedness to permit such repurchase of the 6 5/8% Notes.

     (c) Holders electing to have an 6 5/8% Note purchased will be required to surrender the 6 5/8% Note, with the “Option of Holder to Elect Purchase” on the reverse form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. Holders will be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the purchase date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the 6 5/8% Note which was delivered for purchase by the Holder and a statement that such Holder is withdrawing its election to have such 6 5/8% Note purchased.

     (d) On the purchase date, all 6 5/8% Notes purchased by the Company under this Section shall be delivered by the Company to the Trustee for cancellation, and the Company shall pay the purchase price plus accrued and unpaid interest, if any, to the Holders entitled thereto.

     (e) Notwithstanding the foregoing provisions of this Section, the Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 1016 and purchases all 6 5/8% Notes validly tendered and not withdrawn under such Change of Control Offer.

     (f) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection

56

with the repurchase of 6 5/8% Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section by virtue of its compliance with such securities laws or regulations.

Section 1017. Future Guarantors.

     The Company shall cause each Restricted Subsidiary that Guarantees or secures any Indebtedness of the Company to, at the same time, execute and deliver to the Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary will Guarantee payment of the Securities on the same terms and conditions as those set forth in this Indenture.

Section 1018. Covenant Suspension.

     (a) During any period that the 6 5/8% Notes have a rating equal to or higher than BBB- by S&P and Baa3 by Moody’s (each, an “Investment Grade Rating”) and no Default has occurred and is continuing, the Company and the Restricted Subsidiaries will not be subject to Sections 1010(a) through (d), 1011, 1012, 1014, 1015, 1017 and 801(a)(3) (collectively, the “Suspended Covenants”).

     (b) In the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the operation of clause (a) of this Section 1018, and subsequently one or both of S&P and Moody’s downgrades the rating assigned to the 6 5/8% Notes below their respective Investment Grade Rating, then the Company and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants (subject to subsequent suspension of the 6 5/8% Notes again receive Investment Grade Ratings), and, with respect to Restricted Payments proposed to be made after the time of such downgrade, the permissibility of such proposed Restricted Payments will be calculated in accordance with Section 1011 as though Section 1011 had been in effect since the Issue Date, it being understood, however, that no actions taken by the Company or any Restricted Subsidiary during the suspension period shall constitute a Default or an Event of Default under the Suspended Covenants.

     SECTION 9. Amendments to Article Eleven of the Original Indenture.

            (a) Section 1105 of the Original Indenture is amended with respect to the 6 5/8% Notes in its entirety to read as follows:

     On or prior to 11:00 a.m., New York City time, on the Redemption Date for any 6 5/8% Notes, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money, in immediately available funds, sufficient to pay the Redemption Price of and accrued interest on (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date that is on or prior to the Redemption Date) such Securities or any portions thereof that are to be redeemed

57

on that date, it being understood that the amount of money to be deposited by the Company in relation to a mandatory redemption pursuant to Section 1109 shall take into consideration the amount of money deposited by the Escrow Agent with the Trustee or a Paying Agent to fund such redemption.

            (b) Section 1107 of the Original Indenture is amended with respect to the 6 5/8% Notes to add the following paragraph thereto:

     Any 6 5/8% Note of $1,000 or less principal amount shall be redeemed only as a whole and not in part.

            (c) Article Eleven of the Original Indenture is amended with respect to the 6 5/8% Notes by adding Sections 1108, 1109 and 1110 as follows:

Section 1108. Optional Redemption.

     (a) Except as set forth in the following paragraphs of this Section 1108, the 6 5/8% Notes will not be redeemable at the option of the Company prior to September 1, 2009. Starting on that date, the Company may redeem all or any portion of the 6 5/8% Notes, upon no less than 30 nor more than 60 days’ prior notice, at the Redemption Prices set forth below, plus 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 the relevant interest payment date). The following prices are for 6 5/8% Notes redeemed during the 12-month period commencing on September 1 of the years set forth below, and are expressed as percentages of principal amount:

     (b) The Company may on any one or more occasions prior to September 1, 2007, redeem up to 35% of the aggregate principal amount of the 6 5/8% Notes (including any Additional 6 5/8% Notes) originally issued prior to the Redemption Date with the Net Proceeds of one or more Public Equity Offerings at a Redemption Price of 106.625% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of redemption, subject to the right of holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date, provided that at least 65% of the aggregate principal amount of the 6 5/8% Notes (including any Additional 6 5/8% Notes) originally issued prior to the Redemption Date remains Outstanding after the occurrence of such redemption. Any such redemption shall occur not later than 90 days after the date of the closing of any such Public Equity Offering upon not less than 30 nor more than 60 days’ prior notice. The redemption shall be made in accordance with procedures set forth in this Indenture.

58

Redemption Date. For purposes of Section 1104, it shall be sufficient if a notice of redemption pursuant to this Section 1108(c) shall describe the method for determining the Redemption Price in lieu of stating the Redemption Price.

Section 1109. No Mandatory Sinking Fund.

     There will be no mandatory sinking fund payments for the 6 5/8% Notes.

     SECTION 10. Amendments to Article Thirteen the Original Indenture.

          (a) Section 1302 of the Original Indenture is amended in its entirety with respect to the 6 5/8% Notes to read as follows:

Section 1302. Defeasance and Discharge.

     Upon the Company’s exercise of its option to have this Section applied to the 6 5/8% Notes, (i) the Company shall be deemed to have been discharged from its obligations hereunder as provided in this Section, (ii) payment of the 6 5/8% Notes may not be accelerated because of an Event of Default with respect thereto and (iii) the provisions of Articles Fourteen through Sixteen shall cease to be effective with respect to the 6 5/8% Notes as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by the 6 5/8% Notes and to have satisfied all its other obligations under the 6 5/8% Notes and this Indenture insofar as the 6 5/8% Notes are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following, which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of the 6 5/8% Notes to receive, solely from the trust fund described in Section 1304 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on the 6 5/8% Notes when payments are due, (2) the Company’s obligations with respect to the 6 5/8% Notes under Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Company may exercise its option (if any) to have this Section applied to the 6 5/8% Notes notwithstanding the prior exercise of its option (if any) to have Section 1303 applied to the 6 5/8% Notes.

     (b) Section 1303 of the Original Indenture is amended in its entirety with respect to the 6 5/8% Notes to read as follows:

Section 1303. Covenant Defeasance.

     Upon the Company’s exercise of its option to have this Section applied to the 6 5/8% Notes, (i) the Company shall be released from its obligations under Section 801(a)(3), Sections 1005 through 1017, inclusive, (ii) payment of the Notes may not be accelerated because of an Event of Default specified in clause (4), clause (5) (with respect only to Subsidiary Guarantors or Significant Subsidiaries), clause (6) (with respect only to Subsidiary Guarantors or Significant Subsidiaries), clause (7), clause (8) or clause (9) of Section 501 or because of the failure of the Company to comply with Section 801(a)(3) and (iii) the provisions of Articles

59

Fourteen through Sixteen shall cease to be effective with respect to the 6 5/8% Notes as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to the 6 5/8% Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section or Article Fourteen, Fifteen or Sixteen, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article Fourteen, Fifteen or Sixteen, or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of this Indenture and the 6 5/8% Notes shall be unaffected thereby.

     SECTION 11. Amendments to Article Fourteen of the Original Indenture.

            (a) Article Fourteen of the Original Indenture is superseded with respect to the 6 5/8% Notes by the following provisions:

ARTICLE FOURTEEN

Subordination

Section 1401. Agreement to Subordinate.

     The Company agrees, and each Noteholder by accepting an 6 5/8% Note agrees, that the payment of the principal of, premium, if any, and interest on the 6 5/8% Notes and any other payment obligation of the Company in respect of the 6 5/8% Notes (including any obligation to purchase 6 5/8% Notes) is subordinated in right of payment, to the extent and in the manner provided in this Article Fourteen, to the prior payment in full of all Senior Indebtedness of the Company, including the obligations of the Company under the Revolving Credit Facility, and that the subordination is for the benefit of and shall be enforceable directly by the holders of such Senior Indebtedness. The 6 5/8% Notes shall in all respects rank pari passu with all other Senior Subordinated Indebtedness of the Company (including, without limitation, the 2012 Notes) and only Indebtedness of the Company that is Senior Indebtedness of the Company shall rank senior to the 6 5/8% Notes in accordance with the provisions set forth herein. All provisions of this Article Fourteen shall be subject to Section 1412.

Section 1402. Liquidation, Dissolution, Bankruptcy.

     Upon any payment or distribution of the assets of the Company upon a liquidation, dissolution or reorganization of or similar proceeding relating to the Company or its property:

     (1) holders of Senior Indebtedness of the Company shall be entitled to receive payment in full in cash or cash equivalents of such Senior Indebtedness before Noteholders shall be entitled to receive any payment; and

     (2) until such Senior Indebtedness is paid in full in cash or cash equivalents, any payment or distribution to which Noteholders would be entitled but for this Article Fourteen shall be made to holders of such Senior Indebtedness as their interests may appear, except that Noteholders may receive shares of stock and any debt securities that are subordinated to such Senior Indebtedness to at least the same extent as the 6 5/8% Notes.

60

Section 1403. Default on Senior Indebtedness of the Company.

     The Company shall not pay the principal of, premium, if any, or interest on the 6 5/8% Notes or any other payment obligation in respect of the 6 5/8% Notes (including any obligation to purchase the 6 5/8% Notes) or make any deposit pursuant to Article Four or Thirteen and may not purchase, redeem or otherwise retire any 6 5/8% Notes (collectively, “pay the 6 5/8% Notes”) if either of the following (a “Payment Default”) occurs: (1) any Obligation on Designated Senior Indebtedness of the Company is not paid in full when due; or (2) any other default on Designated Senior Indebtedness of the Company occurs and the maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms; unless, in either case, the Payment Default has been cured or waived and any such acceleration has been rescinded or such Designated Senior Indebtedness has been paid in full in cash or cash equivalents; provided, however, that the Company shall be entitled to pay the 6 5/8% Notes without regard to the foregoing if the Company and the Trustee receive written notice approving such payment from the Representatives of all Designated Senior Indebtedness with respect to which the Payment Default has occurred and is continuing.

     During the continuance of any default (other than a Payment Default) with respect to any Designated Senior Indebtedness of the Company pursuant to which the maturity thereof may be accelerated without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Company shall not pay the 6 5/8% Notes for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee and the Company of a written notice (a “Blockage Notice”) of such default from the Representative of such Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and ending 179 days thereafter. The Payment Blockage Period shall end earlier if such Payment Blockage Period is terminated: (1) by written notice to the Trustee and the Company from the Person or Persons who gave such Blockage Notice; (2) because the default giving rise to such Blockage Notice is cured, waived or otherwise no longer continuing; or (3) because such Designated Senior Indebtedness has been discharged or repaid in full in cash or cash equivalents.

     Notwithstanding the provisions described in the preceding paragraph, unless the holders of such Designated Senior Indebtedness or the Representative of such Designated Senior Indebtedness shall have accelerated the maturity of such Designated Senior Indebtedness, the Company shall be permitted to resume payments on the 6 5/8% Notes after the end of such Payment Blockage Period. The 6 5/8% Notes shall not be subject to more than one Payment Blockage Period in any consecutive 360-day period irrespective of the number of defaults with respect to Designated Senior Indebtedness of the Company during such period; provided, however, that in no event may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any consecutive 360-day period, and there must be 181 days during any consecutive 360-day period during which no Payment Blockage Period is in effect.

61

Section 1404. Acceleration of Payment of 6 5/8% Notes.

     If payment of the 6 5/8% Notes is accelerated because of an Event of Default, the Company or the Trustee shall promptly notify the holders of Designated Senior Indebtedness of the Company (or their Representatives) of the acceleration.

Section 1405. When Distribution Must Be Paid Over; Reinstatement of Senior Indebtedness.

     If a distribution is made to Noteholders that because of this Article Fourteen should not have been made to them, the Noteholders who receive the distribution shall hold it in trust for holders of Senior Indebtedness of the Company and pay it over to them as their interests may appear.

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

Section 1406. Subrogation.

     After all Senior Indebtedness of the Company is paid in full and until the 6 5/8% Notes are paid in full, Noteholders shall be subrogated to the rights of holders of such Senior Indebtedness to receive distributions applicable to such Senior Indebtedness. A distribution made under this Article Fourteen to holders of such Senior Indebtedness which otherwise would have been made to Noteholders is not, as between the Company and Noteholders, a payment by the Company on such Senior Indebtedness.

Section 1407. Relative Rights.

     This Article Fourteen defines the relative rights of Noteholders and holders of Senior Indebtedness of the Company. Nothing in this Indenture shall:

     (1) impair, as between the Company and Noteholders, the obligation of the Company, which is absolute and unconditional, to pay principal of and interest on the 6 5/8% Notes in accordance with their terms; or

     (2) prevent the Trustee or any Noteholder from exercising its available remedies upon a Default, subject to the rights of holders of Senior Indebtedness of the Company to receive distributions otherwise payable to Noteholders.

62

Section 1408. Subordination May Not Be Impaired by Company.

     No right of any present or future holders of any Senior Indebtedness of the Company to enforce subordination as provided in this Indenture will at any time in any way be prejudiced or impaired by noncompliance by the Company with the terms of this Indenture, regardless of any knowledge thereof that any such holder of Senior Indebtedness may have or otherwise be charged with.

Section 1409. Rights of Trustee and Paying Agent; Rights of Holders of Senior Indebtedness.

     Notwithstanding Section 1403, the Trustee or Paying Agent shall continue to make payments on the 6 5/8% Notes and shall not be charged with knowledge of the existence of facts that under this Article Fourteen would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Trust Officer of the Trustee receives notice satisfactory to it that such payments are prohibited by this Article Fourteen. The Company, the Security Registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness of the Company shall be entitled to give the notice; provided, however, that, if an issue of Senior Indebtedness of the Company has a Representative, only the Representative shall be entitled to give the notice.

     The Trustee in its individual or any other capacity shall be entitled to hold Senior Indebtedness of the Company with the same rights it would have if it were not Trustee. The Security Registrar and the Paying Agent shall be entitled to do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article Fourteen with respect to any Senior Indebtedness of the Company which may at any time be held by it, to the same extent as any other holder of such Senior Indebtedness; and nothing in Article Six shall deprive the Trustee of any of its rights as such holder. Nothing in this Article Fourteen shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607.

     The holders of Senior Indebtedness may, at any time and from time to time subject to the terms of such Senior Indebtedness, without the consent of or notice to the Trustee or the Noteholders, without incurring responsibility to the Noteholders and without impairing or releasing the subordination provided in this Indenture or the obligations hereunder of the Noteholders to the holders of Senior Indebtedness, do any one or more of the following:

     (1) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding or secured;

     (2) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness;

     (3) release any Person liable in any manner for the collection of Senior Indebtedness; and

     (4) exercise or refrain from exercising any rights against the Company and any other Person.

Section 1410. Distribution or Notice to Representative.

63

     Whenever any Person is to make a distribution or give a notice to holders of Senior Indebtedness of the Company, such Person shall be entitled to make such distribution or give such notice to their Representative (if any).

Section 1411. Article Fourteen Not to Prevent Events of Default or Limit Right to Accelerate.

     The failure to make a payment pursuant to the 6 5/8% Notes by reason of any provision in this Article Fourteen shall not be construed as preventing the occurrence of a Default. Nothing in this Article Fourteen shall have any effect on the right of the Noteholders or the Trustee to accelerate the maturity of the 6 5/8% Notes.

Section 1412. Trust Moneys and Escrow Funds Not Subordinated.

     Notwithstanding anything contained herein to the contrary, payments from any money or the proceeds of U.S. Government Obligations held in trust under Article Four or Thirteen by the Trustee for the payment of principal of and interest on the 6 5/8% Notes shall not be subordinated to the prior payment of any Senior Indebtedness of the Company or subject to the restrictions set forth in this Article Fourteen, and none of the Noteholders shall be obligated to pay over any such amount to the Company or any holder of Senior Indebtedness of the Company or any other creditor of the Company.

Section 1413. Trustee Entitled to Rely.

     Upon any payment or distribution pursuant to this Article Fourteen, the Trustee and the Noteholders shall be entitled to rely (1) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 1402 are pending, (2) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Noteholders or (3) upon the Representatives of Senior Indebtedness of the Company for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of such Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article Fourteen. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness of the Company to participate in any payment or distribution pursuant to this Article Fourteen, the Trustee shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article Fourteen, and, if such evidence is not furnished, the Trustee shall be entitled to defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 601 and 603 shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article Fourteen.

Section 1414. Trustee to Effectuate Subordination.

     Each Noteholder by accepting an 6 5/8% Note authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination

64

provided in this Article Fourteen and appoints the Trustee as attorney-in-fact for any and all such purposes.

Section 1415. Trustee Not Fiduciary for Holders of Senior Indebtedness of the Company.

     The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness of the Company and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Noteholders or the Company or any other Person, money or assets to which any holders of Senior Indebtedness of the Company shall be entitled by virtue of this Article Fourteen or otherwise.

Section 1416. Reliance by Holders of Senior Indebtedness of the Company on Subordination Provisions.

     Each Noteholder by accepting an 6 5/8% Note acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Indebtedness of the Company, whether such Senior Indebtedness was created or acquired before or after the issuance of the 6 5/8% Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness and such holder of such Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness.

     SECTION 12. Subsidiary Guaranties.

            (a) The Original Indenture is amended with respect to the 6 5/8% Notes by adding Articles Fifteen and Sixteen as follows:

ARTICLE FIFTEEN

Subsidiary Guaranties

Section 1501. Guaranties.

     Each Subsidiary Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the 6 5/8% Notes when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the 6 5/8% Notes and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the 6 5/8% Notes (all the foregoing being hereinafter collectively called the “Guarantied Obligations”). Each Subsidiary Guarantor further agrees that the Guarantied Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor will remain bound under this Article Fifteen notwithstanding any extension or renewal of any Guarantied Obligation.

     Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guarantied Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the 6 5/8% Notes or

65

the Guarantied Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the 6 5/8% Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the 6 5/8% Notes or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Guarantied Obligations or any of them; (e) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guarantied Obligations; or (f) except as set forth in Section 1506, any change in the ownership of such Subsidiary Guarantor.

     Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guarantied Obligations.

     Each Subsidiary Guaranty is, to the extent and in the manner set forth in Article Sixteen, subordinated and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Senior Indebtedness of the Subsidiary Guarantor giving such Subsidiary Guaranty and each Subsidiary Guaranty is made subject to such provisions of this Indenture.

     Except as expressly set forth in Sections 1502 and 1506, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guarantied Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the 6 5/8% Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity, except for the payment in full of the Guarantied Obligations.

     Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guarantied Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

     In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guarantied Obligation when and as the same shall become due, whether at Stated Maturity, by acceleration, by redemption or

66

otherwise, or to perform or comply with any other Guarantied Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (1) the unpaid amount of such Guarantied Obligations, (2) accrued and unpaid interest on such Guarantied Obligations (but only to the extent not prohibited by law) and (3) all other monetary Guarantied Obligations of the Company to the Holders and the Trustee.

     Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any Guarantied Obligations until payment in full of all Guarantied Obligations and all obligations to which the Guarantied Obligations are subordinated as provided in Article Sixteen. Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Guarantied Obligations may be accelerated as provided in Article Five for the purposes of such Subsidiary Guarantor’s Subsidiary Guaranty herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantied Obligations, and (y) in the event of any declaration of acceleration of such Guarantied Obligations as provided in Article Five, such Guarantied Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section.

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

Section 1502. Limitation on Liability.

     Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guarantied Obligations with respect to any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 1503. Successors and Assigns.

     This Article Fifteen shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the 6 5/8% Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 1504. No Waiver.

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

67

Section 1505. Modification.

     No modification, amendment or waiver of any provision of this Article Fifteen, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.

Section 1506. Release of Subsidiary Guarantor.

     Upon (1) the sale or other disposition (including by way of consolidation or merger) of all of the Capital Stock of a Subsidiary Guarantor (in each case other than a sale or disposition to the Company or an Affiliate of the Company) and as permitted by this Indenture, (2) the liquidation and dissolution of a Subsidiary Guarantor, (3) the exercise by the Company of its option (A) to satisfy and discharge the Indenture with respect to the 6 5/8% Notes pursuant to Article Four or (B) to effect Defeasance or Covenant Defeasance pursuant to Article Thirteen or (4) the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary, such Subsidiary Guarantor shall be deemed released from all obligations under this Indenture and the 6 5/8% Notes without any further action required on the part of the Trustee, the Company, such Subsidiary Guarantor or any Holder. At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release.

Section 1507 Contribution.

     Each Subsidiary Guarantor that makes a payment under its Subsidiary Guaranty shall be entitled upon payment in full of all Guarantied Obligations to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

ARTICLE SIXTEEN

Subordination of Subsidiary Guaranties

Section 1601. Agreement to Subordinate.

     Each Subsidiary Guarantor agrees, and each Noteholder by accepting an 6 5/8% Note agrees, that the payment of such Subsidiary Guarantor’s Subsidiary Guaranty (including any amounts in respect of the principal of, premium, if any, or interest on the 6 5/8% Notes and any other payment obligation in respect of the 6 5/8% Notes, including any obligation of the Company to purchase 6 5/8% Notes) is subordinated in right of payment, to the extent and in the manner provided in this Article Sixteen, to the prior payment in full of all Senior Indebtedness of such Subsidiary Guarantor, including such Subsidiary Guarantor’s Guarantee of Senior Indebtedness of the Company, and that the subordination is for the benefit of and shall be enforceable directly by the holders of such Senior Indebtedness. The Guarantied Obligations of a Subsidiary Guarantor shall in all respects rank pari passu with all other Senior Subordinated Indebtedness of such Subsidiary Guarantor and only Indebtedness of such Subsidiary Guarantor that is Senior

68

Indebtedness of such Subsidiary Guarantor shall rank senior to the Guarantied Obligations of such Subsidiary Guarantor in accordance with the provisions set forth herein. All provisions of this Article Sixteen shall be subject to Section 1612.

Section 1602. Liquidation, Dissolution, Bankruptcy.

     Upon any payment or distribution of the assets of any Subsidiary Guarantor upon a liquidation, dissolution or reorganization of or similar proceeding relating to such Subsidiary Guarantor or its property:

     (1) holders of Senior Indebtedness of such Subsidiary Guarantor shall be entitled to receive payment in full in cash or cash equivalents of such Senior Indebtedness before Noteholders shall be entitled to receive any payment pursuant to the Subsidiary Guaranty of such Subsidiary Guarantor; and

     (2) until the Senior Indebtedness of such Subsidiary Guarantor is paid in full in cash or cash equivalents, any payment or distribution to which Noteholders would be entitled but for this Article Sixteen shall be made to holders of such Senior Indebtedness as their interests may appear, except that Noteholders may receive shares of stock and any debt securities of such Subsidiary Guarantor that are subordinated to such Senior Indebtedness to at least the same extent as its Subsidiary Guaranty.

Section 1603. Default on Senior Indebtedness of Subsidiary Guarantor.

     No Subsidiary Guarantor shall make any payment under its Subsidiary Guaranty, whether in respect of the principal of, premium, if any, or interest on the 6 5/8% Notes or any other payment obligation in respect of the 6 5/8% Notes (including any obligation of the Company to purchase 6 5/8% Notes) or make any deposit pursuant to Article Four or Thirteen and may not purchase, redeem or otherwise retire or defease any 6 5/8% Notes or other Guarantied Obligations (collectively, “pay its Subsidiary Guaranty”) if either of the following (a “Payment Default”) occurs (1) any Obligation on Designated Senior Indebtedness of such Subsidiary Guarantor is not paid in full when due; or (2) any other default on Designated Senior Indebtedness of such Subsidiary Guarantor occurs and the maturity of such Designated Senior Indebtedness is accelerated in accordance with its terms; unless, in either case, the Payment Default has been cured or waived and any such acceleration has been rescinded or such Designated Senior Indebtedness has been paid in full in cash or cash equivalents; provided, however, that any Subsidiary Guarantor shall be entitled to pay its Subsidiary Guaranty without regard to the foregoing if such Subsidiary Guarantor and the Trustee receive written notice approving such payment from the Representatives of all Designated Senior Indebtedness with respect to which the Payment Default has occurred and is continuing.

     During the continuance of any default (other than a Payment Default) with respect to any Designated Senior Indebtedness of such Subsidiary Guarantor pursuant to which the maturity thereof may be accelerated without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, such Subsidiary Guarantor shall not pay its Subsidiary Guaranty for a period (a “Payment Blockage Period”) commencing upon the receipt by the Trustee and such Subsidiary Guarantor of written notice (a

69

“Blockage Notice”) of such default from the Representative of such Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period and ending 179 days thereafter. The Payment Blockage Period shall end earlier if such Payment Blockage Period is terminated: (1) by written notice to the Trustee and such Subsidiary Guarantor from the Person or Persons who gave such Blockage Notice; (2) because the default giving rise to such Blockage Notice is cured, waived or otherwise no longer continuing; or (3) because such Designated Senior Indebtedness has been discharged or repaid in full in cash or cash equivalents.

     Notwithstanding the provisions described in the preceding paragraph, unless the holders of such Designated Senior Indebtedness giving such Payment Notice or the Representative of such Designated Senior Indebtedness shall have accelerated the maturity of such Designated Senior Indebtedness, any Subsidiary Guarantor shall be permitted to resume payments pursuant to its Subsidiary Guaranty after the end of such Payment Blockage Period. No Subsidiary Guarantor shall be subject to more than one Blockage Period in any consecutive 360-day period irrespective of the number of defaults with respect to Designated Senior Indebtedness of such Subsidiary Guarantor during such period; provided, however, that in no event may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any consecutive 360-day period, and there must be 181 days during any consecutive 360-day period during which no Payment Blockage Period is in effect.

Section 1604. Demand for Payment.

     If a demand for payment is made by the Trustee on a Subsidiary Guarantor pursuant to Article Fifteen, the Trustee shall promptly notify the holders of Designated Senior Indebtedness of such Subsidiary Guarantor (or their Representatives) of such demand.

Section 1605. When Distribution Must Be Paid Over; Reinstatement of Senior Indebtedness.

     If a distribution is made to Noteholders that because of this Article Sixteen should not have been made to them, the Noteholders who receive the distribution shall hold it in trust for holders of Senior Indebtedness of the applicable Subsidiary Guarantor and pay it over to them or their Representatives as their interests may appear.

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

Section 1606. Subrogation.

     After all Senior Indebtedness of a Subsidiary Guarantor is paid in full and until the 6 5/8% Notes are paid in full, Noteholders shall be subrogated to the rights of holders of such Senior Indebtedness to receive distributions applicable to Senior Indebtedness of such Subsidiary

70

Guarantor. A distribution made under this Article Sixteen to holders of such Senior Indebtedness which otherwise would have been made to Noteholders is not, as between the relevant Subsidiary Guarantor and Noteholders, a payment by such Subsidiary Guarantor on such Senior Indebtedness.

Section 1607. Relative Rights.

     This Article Sixteen defines the relative rights of Noteholders and holders of Senior Indebtedness of a Subsidiary Guarantor. Nothing in this Indenture shall:

     (1) impair, as between a Subsidiary Guarantor and Noteholders, the obligation of such Subsidiary Guarantor, which is absolute and unconditional, to pay its Subsidiary Guaranty to the extent set forth in Article Fifteen; or

     (2) prevent the Trustee or any Noteholder from exercising its available remedies upon a default by such Subsidiary Guarantor under its Subsidiary Guaranty, subject to the rights of holders of Senior Indebtedness of such Subsidiary Guarantor to receive distributions otherwise payable to Noteholders.

Section 1608. Subordination May Not Be Impaired by Company.

     No right of any present or future holders of any Senior Indebtedness of any Subsidiary Guarantor to enforce subordination as provided in this Indenture will at any time in any way be prejudiced or impaired by noncompliance by such Subsidiary Guarantor with the terms of this Indenture, regardless of any knowledge thereof that any such Holder of Senior Indebtedness may have or otherwise be charged with.

Section 1609. Rights of Trustee and Paying Agent; Rights of Holders of Senior Indebtedness.

     Notwithstanding Section 1603, the Trustee or Paying Agent shall continue to make payments on any Subsidiary Guaranty and shall not be charged with knowledge of the existence of facts that under this Article Sixteen would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a Trust Officer of the Trustee receives written notice satisfactory to it that such payments are prohibited by this Article Sixteen. The Company, the relevant Subsidiary Guarantor, the Security Registrar, the Paying Agent, a Representative or a holder of Senior Indebtedness of such Subsidiary Guarantor shall be entitled to give the notice; provided, however, that, if an issue of Senior Indebtedness of any Subsidiary Guarantor has a Representative, only the Representative shall be entitled to give the notice.

     The Trustee in its individual or any other capacity shall be entitled to hold Senior Indebtedness of any Subsidiary Guarantor with the same rights it would have if it were not the Trustee. The Security Registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article Sixteen with respect to any Senior Indebtedness of any Subsidiary Guarantor which may at any time be held by it, to the same extent as any other holder of such Senior Indebtedness; and nothing in Article Six shall deprive the Trustee of any of its rights as such holder. Nothing in this Article Sixteen shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607.

71

     The holders of Senior Indebtedness may, at any time and from time to time subject to the terms of such Senior Indebtedness, without the consent of or notice to the Trustee or the Noteholders, without incurring responsibility to the Noteholders and without impairing or releasing the subordination provided in this Indenture or the obligations hereunder of the Noteholders to the holders of Senior Indebtedness, do any one or more of the following:

     (1) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding or secured;

     (2) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness;

     (3) release any Person liable in any manner for the collection of Senior Indebtedness; and

     (4) exercise or refrain from exercising any rights against any Subsidiary Guarantor and any other Person.

Section 1610. Distribution or Notice to Representative.

     Whenever any Person is to make a distribution or give a notice to holders of Senior Indebtedness of any Subsidiary Guarantor, such Person shall be entitled to make such distribution or give such notice to their Representative (if any).

Section 1611. Article Sixteen Not to Prevent Events of Default or Limit Right to Demand Payment.

     The failure to make a payment pursuant to a Subsidiary Guaranty by reason of any provision in this Article Sixteen shall not be construed as preventing the occurrence of a Default. Nothing in this Article Sixteen shall have any effect on the right of the Noteholders or the Trustee to make a demand for payment on any Subsidiary Guarantor pursuant to its Subsidiary Guaranty.

Section 1612. Trust Moneys and Escrow Funds Not Subordinated.

     Notwithstanding anything contained herein to the contrary, payments from any money or the proceeds of U.S. Government Obligations held in trust under Article Four or Thirteen by the Trustee for the payment of principal of and interest on the 6 5/8% Notes shall not be subordinated to the prior payment of any Senior Indebtedness of any Subsidiary Guarantor or subject to the restrictions set forth in this Article Sixteen, and none of the Noteholders shall be obligated to pay over any such amount to any Subsidiary Guarantor or any holder of Senior Indebtedness of any Subsidiary Guarantor or any other creditor of any Subsidiary Guarantor.

Section 1613. Trustee Entitled to Rely.

     Upon any payment or distribution pursuant to this Article Sixteen, the Trustee and the Noteholders shall be entitled to rely (1) upon any order or decree of a court of competent

[FORM OF THE REVERSE OF 6 5/8% NOTE]

NEWFIELD EXPLORATION COMPANY

6 5/8% Senior Subordinated Note due 2014

     1. Indenture; Limitations.

     The Company issued the 6 5/8% Notes under the Subordinated Indenture dated as of December 10, 2001 (the “Original Indenture”), as supplemented and amended by the Second Supplemental Indenture dated as of August 18, 2004 (the Original Indenture as so supplemented and amended being hereinafter referred to as the “Indenture”), between the Company and Wachovia Bank, National Association, as trustee (the “Trustee”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the 6 5/8% Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The 6 5/8% Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this 6 5/8% Note and the terms of the Indenture, the terms of the Indenture shall control.

     The 6 5/8% Notes are senior subordinated obligations of the Company and the aggregate principal amount of the 6 5/8% Notes which may be issued, executed, authenticated, delivered and outstanding is unlimited (subject to Section 1 of the Second Supplemental Indenture). The Company may, subject to Section 1010 of the Indenture, issue Additional 6 5/8% Notes under the Indenture in either a limited or an unlimited aggregate principal amount. This 6 5/8% Note is one of the 6 5/8% Notes issued on the Issue Date in an aggregate principal amount of $325,000,000. Any Additional 6 5/8% Notes that may be issued, together with the 6 5/8% Notes issued on the Issue Date and any Exchange Notes issued in exchange for either such 6 5/8% Notes or such Additional 6 5/8% Notes, shall be treated as a single class under the Indenture.

     2. Principal and Interest.

     The Company will pay the principal of this 6 5/8% Note on September 1, 2014.

     The Company promises to pay interest on the principal amount of this 6 5/8% Note on each March 1 and September 1 (each an “Interest Payment Date”), as set forth below, at the rate per annum shown above.

     Interest will be payable semiannually (to the holders of record of the 6 5/8% Notes at the close of business on the February 15 or August 15 immediately preceding the Interest Payment Date) on each Interest Payment Date, commencing March 1, 2005.

     Interest on the 6 5/8% Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from August 18, 2004, provided that, if there is no existing Default in the payment of interest and this 6 5/8% Note is authenticated between a Regular Record Date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

A-3

     The Company shall pay interest on overdue principal at the rate borne by the 6 5/8% Notes plus 1% per annum, and it shall pay interest on overdue installments of interest, to the extent lawful, at the rate borne by the 6 5/8% Notes plus 1% per annum.

     3. Method of Payment.

     The Company will pay interest (except Defaulted Interest) on the principal amount of the 6 5/8% Notes as provided above on each Interest Payment Date to the persons who are Holders (as reflected in the Security Register at the close of business on the February 15 and August 15 immediately preceding the relevant Interest Payment Date), in each case, even if the 6 5/8% Note is canceled on registration of transfer, registration of exchange, redemption or repurchase after such record date and on or before the Interest Payment Date, provided that, with respect to the payment of principal, the Company will make payment to the Holder that surrenders this 6 5/8% Note to a Paying Agent on or after its Maturity.

     The Company will pay principal, premium, if any, and as provided above, interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company will make such payments (i) by wire transfer of immediately available funds to any account maintained in the United States with respect to Global Securities or 6 5/8% Notes held in certificated form with an aggregate principal amount in excess of $1,000,000 whose Holder has requested such method of payment and provided wire transfer instructions to the Paying Agent or (ii) by check payable in such money mailed to a Holder’s registered address with respect to any certificated 6 5/8% Notes. If a payment date is a date other than a Business Day at a Place of Payment, payment may be made at that place on the next succeeding day that is a Business Day and no interest shall accrue for the intervening period.

     4. Paying Agent and Security Registrar.

     Initially, the Trustee will act as Paying Agent and Security Registrar in relation to the 6 5/8% Notes. The Company may change any authenticating agent, Paying Agent or Security Registrar without notice.

     5. Optional and Mandatory Redemption.

     The 6 5/8% Notes are subject to both optional and mandatory redemption, either as a whole or in some cases in part, at the times, under the circumstances, upon the giving of prior notices to Holders and at the Redemption Prices described in Article Eleven of the Indenture.

     6. Subordination.

     The 6 5/8% Notes are subordinated to Senior Indebtedness of the Company. To the extent provided in the Indenture, Senior Indebtedness of the Company must be paid before the 6 5/8% Notes may be paid. The Company and each Holder by accepting a 6 5/8% Note agree to the subordination provisions contained in the Indenture and authorize the Trustee to give it effect and appoint the Trustee as attorney-in-fact for such purpose.

A-4

     7. Repurchase upon a Change of Control.

     Upon the occurrence of a Change of Control, each Holder of 6 5/8% Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 in principal amount or an integral multiple thereof) of such Holder’s 6 5/8% Notes pursuant to the Change of Control Offer as provided in, and subject to the terms of, the Indenture at a purchase price in cash equal to 101% of the principal amount of the 6 5/8% Notes repurchased, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date).

     8. Denominations; Transfer; Exchange.

     The 6 5/8% Notes are in registered form without coupons in denominations of $1,000 of principal amount and multiples of $1,000 in excess thereof. A Holder may register the transfer of or exchange 6 5/8% Notes in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges imposed on the transaction. The Security Registrar need not register the transfer of or exchange any 6 5/8% Notes selected or called for redemption (except in the case of a 6 5/8% Note redeemed in part, the portion of the 6 5/8% Note not to be redeemed). Also, it need not register the transfer or exchange of any 6 5/8% Notes for a period of 15 days before the day of the mailing of a notice of redemption of 6 5/8% Notes selected for redemption.

     9. Persons Deemed Owners.

     A Holder shall be treated as the owner of a 6 5/8% Note for all purposes.

     10. Unclaimed Money.

     If money for the payment of principal, premium, if any, or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Company at its written request, unless an abandoned property law provides otherwise. After that, Holders entitled to the money must look to the Company for payment, and all liability of the Trustee and the Paying Agent with respect to such money shall cease.

     11. Discharge Prior to Redemption or Maturity.

     Subject to certain conditions, if the Company deposits with the Trustee money or U.S. Government Obligations sufficient to pay the then outstanding principal of, premium, if any, and accrued interest on the 6 5/8% Notes to redemption or Stated Maturity, as applicable, the Company and the Subsidiary Guarantors, if any, may terminate some of or all of their obligations under the Indenture and the 6 5/8% Notes, all as provided in Articles Four and Thirteen of the Indenture.

A-5

waived with the consent of the Holders of at least a majority in principal amount of the 6 5/8% Notes then Outstanding. Without notice to or the consent of any Holder, the parties thereto may amend or supplement the Indenture or the 6 5/8% Notes to, among other things, cure any ambiguity, defect or inconsistency and make any other change that does not adversely affect the interests of any Holder in any material respect.

Within 120 days after the end of each fiscal year, the Company shall deliver to the Trustee an Officers’ Certificate stating whether or not the signers know of any Default or Event of Default under such restrictive covenants.

     (e) a default by the Company or any Restricted Subsidiary under any Indebtedness in an aggregate principal amount greater than $10.0 million (other than Non-recourse Purchase Money Indebtedness) that results in acceleration of the maturity of such Indebtedness, or failure to pay any such Indebtedness at maturity within any

applicable grace period, if such Indebtedness is not repaid or such acceleration is not rescinded within 10 days beyond the applicable grace period or the acceleration as provided in the Indenture;

     (f) one or more judgments or decrees by a court of competent jurisdiction are entered against the Company, a Subsidiary Guarantor or any Significant Subsidiary in an uninsured or unindemnified aggregate amount outstanding at any time in excess of $10.0 million and such judgments or decrees are not discharged, waived, stayed, satisfied or bonded for a period of 60 consecutive days;

     The Indenture provides that if an Event of Default (other than an Event of Default described in clause (g) above) with respect to the 6 5/8% Notes at the time Outstanding shall occur and be continuing, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding 6 5/8% Notes by notice as provided in the Indenture may declare the principal amount of the 6 5/8% Notes, together with accrued and unpaid interest thereon, to be due and payable immediately.

After any such acceleration, but before a judgment or decree based on acceleration, the Holders of at least a majority in aggregate principal amount of the Outstanding 6 5/8% Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, have been cured or waived as provided in the Indenture.

     17. No Recourse Against Others.

Each Holder by accepting a 6 5/8% Note expressly waives and releases all such liability.
