SECTION 1.01 Establishment.

There is hereby established a new series of Securities to be issued under the Indenture, to be designated as the Company’s 6¾% Senior Notes due 2020 (the “Notes”). This Second Supplemental Indenture shall be deemed to satisfy all requirements of Section 301 of the Original Indenture necessary for establishment of the Notes as a series of Securities under the Indenture notwithstanding anything to the contrary therein.

There are to be authenticated and delivered Notes, initially limited in aggregate principal amount of $300,000,000 and no further Notes shall be authenticated and delivered except as provided by the terms of the Original Indenture and the terms of this Second Supplemental Indenture; provided, however, that additional Notes having identical terms and conditions as the Notes other than issue date, the issue price, the date from which interest thereon shall accrue, legends, if any, to be included thereon and the first Interest Payment Date (the “Additional Notes”) may be issued from time to time in the future, without the consent of the Holders of the Notes, in accordance with the provisions of the Indenture. With respect to any Additional Notes, the Company shall set forth in a resolution of the Board of Directors or an Officers’ Certificate, the following information:

(a) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to the Indenture;

(b) the issue date, the issue price, the first Interest Payment Date of such Additional Notes, the date from which interest shall accrue and legends, if any, to be included thereon; and

The Notes and the Additional Notes, if any, shall be considered collectively as a single class for all purposes of the Indenture. Holders of the Notes and the Additional Notes, if any, shall vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Notes or the Additional Notes, if any, shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

The Notes shall be issued in fully registered form without coupons, and only in denominations of $2,000 and larger integral multiples of $1,000. The Notes shall be issued in the form of one or more Global Securities in substantially the form set out in Exhibit A hereto. The initial Depositary with respect to the Notes shall be DTC. Payments in respect of Notes represented by a Global Security (including principal, premium and interest) shall be made by wire transfer of immediately available funds to the accounts specified by DTC.

Each Note shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for.

The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage or DTC rule or usage in addition to those set forth on Exhibit A. The Company and the Trustee shall approve the forms of the Notes and any notation, endorsement or legend on them, such approval to be evidenced by the execution or authentication, respectively, and delivery of the Notes by the Company or the Trustee, respectively. The terms of the Notes set forth in Exhibit A are part of the terms of the Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Second Supplemental Indenture, expressly agree to be bound by such terms.

SECTION 1.02 Book-Entry Provisions.

This Section 1.02 shall apply only to Global Securities deposited with the Trustee, as custodian for DTC.

Each Global Security initially shall (x) be registered in the name of DTC for such Global Security or the nominee of DTC, (y) be delivered to the Trustee as custodian for DTC and (z) bear legends as set forth in Section 202 of the Original Indenture.

Members of, or participants in, DTC (“Agent Members”) shall have no rights under the Indenture with respect to any Global Security held on their behalf by DTC or by the Trustee as the custodian of DTC or under such Global Security, and DTC may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a Holder of a beneficial interest in any Global Security.

In connection with any transfer of a portion of the beneficial interest in a Global Security pursuant to Section 1.03 of this Second Supplemental Indenture to beneficial owners who are required to hold Definitive Securities, the Securities Custodian shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Definitive Securities of like tenor and amount.

In connection with the transfer of an entire Global Security to beneficial owners pursuant to Section 1.03 of this Second Supplemental Indenture, such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations.

The registered Holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes.

SECTION 1.03 Definitive Securities.

Except as provided below, owners of beneficial interests in Global Securities shall not be entitled to receive Definitive Securities. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Definitive Securities in exchange for their beneficial interests in a Global Security upon written request in accordance with DTC’s and the Registrar’s procedures. In addition, Definitive Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if (a) DTC notifies the Company that it is unwilling or unable to continue as depositary for such Global Security or DTC ceases to be a clearing agency registered under the Exchange Act, at a time when DTC is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Company within 90 days of such notice or, (b) the Company executes and delivers to the Trustee and Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable or (c) an Event of Default has occurred and is continuing and the Registrar has received a request from DTC.

In connection with the exchange of a portion of a Definitive Security for a beneficial interest in a Global Security, the Trustee shall cancel such Definitive Security, and the Company shall execute, and the Trustee shall authenticate and deliver, to the transferring Holder a new Definitive Security representing the principal amount not so transferred.

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

(a) the sum of:

(A) estimated proved oil and gas reserves acquired since such year end, which reserves were not reflected in such year end reserve report, and

(B) estimated oil and gas reserves attributable to upward revisions of estimates of proved oil and gas reserves since such year end due to exploration, development or exploitation activities,

in each case calculated in accordance with Commission guidelines (utilizing the prices for the fiscal quarter ending prior to the date of determination),

and decreased by, as of the date of determination, the estimated discounted future net revenues from

(D) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since such year end due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions,

in each case calculated on a pre-tax basis and substantially in accordance with Commission guidelines (utilizing the prices for the fiscal quarter ending prior to the date of determination), in each case as estimated by the Company’s petroleum engineers or any independent petroleum engineers engaged by the Company for that purpose;

(iv) the discounted future net revenues, calculated in accordance with Commission guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in (a)(i) above, would be necessary to fully satisfy the payment obligations of the Company and its Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with respect thereto).

(1) if the Company or any Restricted Subsidiary:

(a) has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated Cash Flow and Consolidated Interest Expense for such period shall be calculated after giving effect on a pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period (except that in making such computation, the amount of Indebtedness under any revolving credit facility outstanding on the date of such calculation shall be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was outstanding or (ii) if such facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such facility to the date of such calculation) and the discharge of any other Indebtedness repaid, repurchased, defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on the first day of such period; and

(b) has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of the period that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of Indebtedness (in each case, other than Indebtedness Incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated Cash Flow and Consolidated Interest Expense for such period shall be

calculated after giving effect on a pro forma basis to such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had occurred on the first day of such period;

(2) if since the beginning of such period the Company or any Restricted Subsidiary shall have made any Asset Disposition or disposed of any company, division, operating unit, segment, business, group of related assets or line of business or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition:

(3) 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 Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged with or into the Company or a Restricted Subsidiary) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of business, Consolidated Cash Flow and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period; and

(4) 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 Incurred any Indebtedness or discharged any Indebtedness, made any disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (1), (2) or (3) above if made by the Company or a Restricted Subsidiary during such period, Consolidated Cash Flow and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto

as if such Person had been a Restricted Subsidiary on the first day of such period and such transaction or transactions had occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations shall be determined in good faith by a responsible financial or accounting officer of the Company (including pro forma expense and cost reductions calculated on a basis consistent with Regulation S-X under the Securities Act). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense 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 to the extent of the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Company, the interest rate shall be calculated by applying such optional rate chosen by the Company.

(3) non-cash interest expense;

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

(5) the interest expense on Indebtedness of another Person that is Guaranteed by such Person or one of its Restricted Subsidiaries or secured by a Lien on assets of such Person or one of its Restricted Subsidiaries;

(6) costs associated with Hedging Obligations (including amortization of fees) provided, however, that if Hedging Obligations result in net benefits rather than costs, such benefits shall be credited to reduce Consolidated Interest Expense unless, pursuant to GAAP, such net benefits are otherwise reflected in Consolidated Net Income;

(7) the consolidated interest expense of such Person and its Restricted Subsidiaries that was capitalized during such period;

(8) the product of (a) all dividends paid or payable, in cash, Cash Equivalents or Indebtedness or accrued during such period on any series of Disqualified Stock of such Person or on Preferred Stock of its Restricted Subsidiaries that are not Subsidiary Guarantors payable to a party other than the Company or a Wholly Owned Subsidiary, times (b) a fraction, the numerator of which is one and the denominator of which is one minus the then current combined Federal, state, provincial and local statutory tax rate of such Person, expressed as a decimal, in each case, on a consolidated basis and in accordance with GAAP;

Notwithstanding anything to the contrary contained herein, commissions, discounts, yield and other fees and charges Incurred in connection with any transaction pursuant to which the Company or its Restricted Subsidiaries may sell, convey or otherwise transfer or grant a security interest in any accounts receivable or related assets shall be included in Consolidated Interest Expense.

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $25.0 million or more;

(7) (a) the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(i) is for relief against the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary in an involuntary case;

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

(iii) orders the winding up or liquidation of the Company or any Significant Subsidiary or a group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary;

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

(8) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $25.0 million (net of any amounts covered by insurance with a reputable and creditworthy insurance company that has not disclaimed liability therefor in writing), which judgments are not paid, discharged or stayed for a period of 60 days; or

However, a Default under clauses (4), (5)(b) and (9)(a)(i) of this Section 3.02 shall not constitute an Event of Default until the Trustee or the Holders of 25% in principal amount of the outstanding Notes notify the Company of the Default and the Company does not cure such Default within the time specified in clauses (4), (5)(b) and (9)(a)(i) of this Section 3.02 after receipt of such notice.

During the continuance of a Default under clause (5)(a) above of this Section 3.02, the interest rate on the Notes shall increase by the Additional Interest.

SECTION 3.03 Acceleration

With respect to the Notes, if an Event of Default (other than an Event of Default described in clause (7) of Section 3.02 of this Second Supplemental Indenture) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Notes by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest shall be immediately due and payable. In the event of a declaration of acceleration of the Notes because an Event of Default described in clause (6) of Section 3.02 of this Second Supplemental Indenture has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if the default triggering such Event of Default pursuant to clause (6) shall be remedied or cured by the Company or a Restricted Subsidiary or waived by the Holders of the relevant Indebtedness within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived. If an Event of Default described in clause (7) of Section 3.02 of this Second Supplemental Indenture occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the outstanding Notes may waive all past defaults (except with respect to nonpayment of principal, premium or interest) and rescind any such acceleration with respect to the Notes and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived.

SECTION 3.04 Control by Holders

Subject to Section 509 of the Original Indenture, with respect to the Notes, the Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee, provided that the Trustee may refuse to follow any direction:

(1) that conflicts with law or the Indenture, and

(2) subject to Sections 601 and 602 of the Original Indenture, that the Trustee determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability;

provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

(4) each Subsidiary Guarantor (unless it is the other party to the transactions above, in which case clause (1) of this Section 4.02 shall apply or unless the Company is the Successor Company and such Subsidiary Guarantor was a Subsidiary Guarantor immediately prior to such transaction) shall have by supplemental indenture confirmed that its Subsidiary Guarantee shall apply to such Person’s obligations in respect of the Indenture and the Notes; and

(5) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, together stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with the Indenture.

For purposes of this Section 4.02, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

SECTION 4.03 Successor Substituted

With respect to the Notes, upon any consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease of all or substantially all its assets in accordance with Section 4.02 of this Second Supplemental Indenture, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture with the same effect as if such successor Person had been named as the Company herein, and the predecessor Company shall be released from its obligations under the Indenture, but, in the case of a lease of all or substantially all its assets, the predecessor Company shall not be released from the obligation to pay the principal of and interest on the Notes.

After an amendment under this Section 5.02 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 5.02.

SECTION 5.03 Supplemental Indentures With Consent of Holders

The Company, any Subsidiary Guarantors and the Trustee may amend or supplement the Indenture or the Notes without notice to any Holder but with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and, subject to the exceptions set forth in Section 514 of the Original Indenture, any past default or compliance with any provisions of the Indenture may be waived with respect to the Notes with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). However, without the consent of each Holder affected, an amendment, supplement or waiver may not:

The Company shall pay interest on overdue principal at the rate specified therefor in the Notes, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

SECTION 6.03 Existence

Subject to Article Four and Section 9.02 of this Second Supplemental Indenture, the Company and each of the Subsidiary Guarantors shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and that of each Restricted Subsidiary and the corporate rights (charter and statutory), licenses and franchises of the Company and each Restricted Subsidiary; provided, however, that the Company shall not be required to preserve any such existence (except the Company), right, license or franchise if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and each of its Restricted Subsidiaries, taken as a whole, and that the loss thereof would not have a material adverse effect on the ability of the Company to perform its obligations under the Notes or the Indenture, provided, further, the Company and each Restricted Subsidiary may merge in accordance with Article Four and Section 9.02 of this Second Supplemental Indenture.

SECTION 6.04 Statement by Officers as to Default

The Company shall deliver to the Trustee, as soon as possible and in any event within thirty days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute a certain Default, an Officers’ Certificate setting forth the details of such Event of Default or default and the action which the Company is taking or proposing to take with respect thereto.

SECTION 6.05 Effectiveness of Covenants

Following the first day on which:

(a) the Notes have an Investment Grade Rating from both of the Ratings Agencies; and

(b) no Default has occurred and is continuing under the Indenture;

the Company and its Restricted Subsidiaries shall not be subject to Sections 6.06, 6.07, 6.08, 6.10, 6.11, 6.12, 6.13, and clause (3) of Section 4.02 of this Second Supplemental Indenture (collectively, the “Suspended Covenants”). If at any time the Notes’ credit rating is downgraded from an Investment Grade Rating by any Rating Agency or a Default or Event of Default occurs and is continuing, then the Suspended Covenants shall thereafter be reinstated as if such covenants had never been suspended (the “Reinstatement Date”) and thereafter be applicable pursuant to the terms of the Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of the Indenture), unless and until the Notes subsequently attain an Investment Grade Rating (in which event the Suspended Covenants shall no longer be in effect for such time that the Notes maintain an Investment Grade Rating and no Default or Event of Default has occurred and is continuing);

provided, however, that no Default, Event of Default or breach of any kind shall be deemed to exist under the Indenture, the Notes or the Subsidiary Guarantees with respect to the Suspended Covenants based on, and none of the Company or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring after the Notes attain an Investment Grade Rating and before any reinstatement of such Suspended Covenants as provided above, or any actions taken at any time pursuant to any contractual obligation arising prior to such reinstatement, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. The period of time between the date of suspension of the covenants and the Reinstatement Date is referred to as the “Suspension Period.”

On the Reinstatement Date, all Indebtedness Incurred during the Suspension Period shall be classified to have been Incurred pursuant to Section 6.06(a) of this Second Supplemental Indenture or one of the clauses set forth in Section 6.06(b) of this Second Supplemental Indenture (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reinstatement Date and after giving effect to Indebtedness Incurred prior to the Suspension Period and outstanding on the Reinstatement Date). To the extent such Indebtedness would not be so permitted to be Incurred pursuant to the Section 6.06(a) or (b) of this Second Supplemental Indenture, such Indebtedness shall be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under clause (4)(b) of Section 6.06(b) of this Second Supplemental Indenture. Calculations made after the Reinstatement Date of the amount available to be made as Restricted Payments under Section 6.08 of this Second Supplemental Indenture shall be made as though Section 6.08 of this Second Supplemental Indenture had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period shall reduce the amount available to be made as Restricted Payments under Section 6.08(a) of this Second Supplemental Indenture.

During any period when the Suspended Covenants are suspended, the Board of Directors of the Company may not designate any of the Company’s Subsidiaries as Unrestricted Subsidiaries pursuant to the Indenture.

SECTION 6.06 Limitation on Indebtedness

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, Incur any Indebtedness (including Acquired Indebtedness); provided, however, that the Company and any Subsidiary Guarantor may Incur Indebtedness if on the date thereof:

(1) the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries is at least 2.50 to 1.00; and

(2) no Default or Event of Default shall have occurred or be continuing or would occur as a consequence of Incurring the Indebtedness or transactions relating to such Incurrence.

(b) Section 6.06(a) of this Second Supplemental Indenture shall not prohibit the Incurrence of the following Indebtedness:

(1) Indebtedness of the Company or any Subsidiary Guarantor Incurred pursuant to Credit Facilities in an aggregate amount outstanding at any time up to the greater of (a) $1.0 billion and (b) 30% of Adjusted Consolidated Net Tangible Assets determined as of the date of the Incurrence of such Indebtedness;

(2) Guarantees by (a) the Company or Subsidiary Guarantors of Indebtedness Incurred by the Company or a Subsidiary Guarantor in accordance with the provisions of the Indenture; provided that in the event such Indebtedness that is being Guaranteed is a Subordinated Obligation or a Guarantor Subordinated Obligation, then the related Guarantee shall be subordinated in right of payment to the Notes or the Subsidiary Guarantee, as the case may be, and (b) Non-Guarantor Restricted Subsidiaries of Indebtedness Incurred by Non-Guarantor Restricted Subsidiaries in accordance with the provisions of the Indenture;

(3) Indebtedness of the Company owing to and held by any Restricted Subsidiary or Indebtedness of a Restricted Subsidiary owing to and held by the Company or any Restricted Subsidiary; provided, however,

(A) if the Company is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes;

(B) if a Subsidiary Guarantor is the obligor on such Indebtedness and the Company or a Subsidiary Guarantor is not the obligee, such Indebtedness is subordinated in right of payment to the Subsidiary Guarantee of such Subsidiary Guarantor; and

(C) (i) any subsequent issuance or transfer of Capital Stock or any other event which results in any such Indebtedness being beneficially held by a Person other than the Company or a Restricted Subsidiary of the Company; and (ii) any sale or other transfer of any such Indebtedness to a Person other than the Company or a Restricted Subsidiary of the Company

shall be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Subsidiary, as the case may be;

(4) Indebtedness represented by (a) the Notes issued on the Issue Date and any Subsidiary Guarantees, (b) any Indebtedness (other than the Indebtedness described in clauses (1), (2), (3), (6), (8), (9) and (10) of this Section 6.06(b)) outstanding on the Issue Date and (c) any Refinancing Indebtedness Incurred in respect of any Indebtedness described in this clause (4) or clause (5) of this Section 6.06(b) or Incurred pursuant to Section 6.06(a) of this Second Supplemental Indenture;

(5) Indebtedness of a Restricted Subsidiary Incurred and outstanding on the date on which such Restricted Subsidiary was acquired by, or merged into, the Company or any Restricted Subsidiary or such Restricted Subsidiary was designated as such (other than Indebtedness Incurred (a) to provide all or any portion of the funds utilized to consummate the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was otherwise acquired by the Company or (b) otherwise in connection with, or in contemplation of, such acquisition); provided, however, that at the time such Restricted Subsidiary is so acquired, merged or designated, the Company would have been able to Incur $1.00 of additional Indebtedness pursuant to Section 6.06(a) of this Second Supplemental Indenture after giving effect to the Incurrence of such Indebtedness pursuant to this clause (5);

(6) Indebtedness under Hedging Obligations that are Incurred in the ordinary course of business (and not for speculative purposes) (a) for the purpose of fixing or hedging interest rate risk with respect to any Indebtedness permitted under the Indenture; (b) for the purpose of fixing or hedging currency exchange rate risk with respect to any currency exchanges; or (c) for the purpose of fixing or hedging commodity price risk with respect to any commodities;

(7) the Incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capitalized Lease Obligations, mortgage financings, purchase money obligations or other payments, in each case Incurred to finance all or any part of the purchase price or cost of construction or improvement of assets or property (other than Capital Stock or other Investments) acquired, constructed or improved by the Company or such Restricted Subsidiary and related financing costs, and Attributable Indebtedness, and all Refinancing Indebtedness Incurred to refund, defease, renew, extend, refinance or replace any Indebtedness Incurred pursuant to this clause (7), in an aggregate principal amount not to exceed $25.0 million at any time outstanding;

(8) Indebtedness Incurred in respect of workers’ compensation claims, self-insurance obligations, performance, surety and similar bonds and completion guarantees provided by the Company or a Restricted Subsidiary in the ordinary course of business;

(9) Indebtedness arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, adjustment of purchase price or similar obligations, in each case, Incurred or assumed in connection with the acquisition or disposition of any business, assets or Capital Stock of a Restricted Subsidiary or any

business or assets of the Company and Refinancing Indebtedness Incurred with the same counterparty in respect thereof, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually paid or received by the Company and its Restricted Subsidiaries in connection with such acquisition or disposition;

(10) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument (except in the case of daylight overdrafts) drawn against insufficient funds or in respect of cash management services provided by a bank or other financial institution, each in the ordinary course of business, provided, however, that such Indebtedness is extinguished within five Business Days of Incurrence;

(12) for the avoidance of doubt, in-kind obligations relating to net oil or natural gas balancing positions arising in the ordinary course of business; and

(13) in addition to the items referred to in clauses (1) through (12) above, Indebtedness of the Company and its Restricted Subsidiaries in an aggregate outstanding principal amount which, when taken together with the principal amount of all other Indebtedness Incurred pursuant to this clause (13) and then outstanding, shall not exceed $20.0 million at any time outstanding.

The Company shall not Incur any Indebtedness under the preceding paragraph if the proceeds thereof are used, directly or indirectly, to refinance any Subordinated Obligations of the Company unless such Indebtedness shall be subordinated to the Notes to at least the same extent as such Subordinated Obligations. No Subsidiary Guarantor shall Incur any Indebtedness under the preceding paragraph if the proceeds thereof are used, directly or indirectly, to refinance any Guarantor Subordinated Obligations of such Subsidiary Guarantor unless such Indebtedness shall be subordinated to the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee to at least the same extent as such Guarantor Subordinated Obligations. No Restricted Subsidiary (other than a Subsidiary Guarantor) may Incur any Indebtedness if the proceeds are used to refinance Indebtedness of the Company or a Subsidiary Guarantor.

(c) For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness Incurred pursuant to and in compliance with, this Section 6.06:

(1) in the event that Indebtedness meets the criteria of more than one of the types of Indebtedness described in this Section 6.06, the Company, in its sole discretion, shall classify such item of Indebtedness on the date of Incurrence and may from time to time re-classify such item of Indebtedness in any manner that complies with this Section 6.06 and only be required to include the amount and type of such Indebtedness in one of such clauses; provided that all Indebtedness outstanding on the Issue Date under the Senior Credit Facility shall be deemed Incurred under clause (1) of Section 6.06(b)

and not Section 6.06(a) of this Second Supplemental Indenture or clause (4) of Section 6.06(b);

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

(3) if obligations in respect of letters of credit are Incurred pursuant to a Credit Facility and are being treated as Incurred pursuant to clause (1) of Section 6.06(b) and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included;

(4) the principal amount of any Disqualified Stock of the Company or a Restricted Subsidiary, or Preferred Stock of a Restricted Subsidiary that is not a Subsidiary Guarantor, shall be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference thereof;

(5) Indebtedness permitted by this Section 6.06 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 6.06 permitting such Indebtedness;

(6) the principal amount of any Indebtedness outstanding in connection with a securitization transaction or series of securitization transactions is the amount of obligations outstanding under the legal documents entered into as part of such transaction that would be characterized as principal if such transaction were structured as a secured lending transaction rather than as a purchase relating to such transaction; and

(7) the amount of Indebtedness issued at a price that is less than the principal amount thereof shall be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

Accrual of interest, accrual of dividends, the accretion of accreted value, the payment of interest in the form of additional Indebtedness, the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock and the incurrence of unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of FAS 133 and similar provisions), in each case shall be deemed not to be Incurrences of Indebtedness for purposes of this Section 6.06. The amount of any Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness.

In addition, the Company shall not permit any of its Unrestricted Subsidiaries to Incur any Indebtedness or issue any shares of Disqualified Stock, other than Non Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary as of such date (and, if such

Indebtedness is not permitted to be Incurred as of such date under this Section 6.06, the Company shall be in Default of this Section 6.06).

For purposes of determining compliance with any U.S. dollar denominated restriction on the Incurrence of Indebtedness, the U.S. dollar equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 6.06, the maximum amount of Indebtedness that the Company may Incur pursuant to this Section 6.06 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(C) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to the Start Date (except as excluded by other provisions of this Section 6.08) would exceed the sum of (all such calculations being made as if this covenant had been in effect as of the Start Date and at all times thereafter):

SECTION 6.10 Limitation on Restrictions on Distributions from Restricted Subsidiaries

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

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

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

(3) transfer any of its property or assets to the Company or any Restricted Subsidiary (it being understood that such transfers shall not include any type of transfer described in clause (1) or (2) above).

(b) Section 6.10(a) of this Second Supplemental Indenture shall not prohibit:

(2) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to any Capital Stock or agreement (including an agreement relating to any Capital Stock or Indebtedness) Incurred by a Restricted Subsidiary on or before the date on which such Restricted Subsidiary became a Restricted Subsidiary or was merged with or into or consolidated with or was acquired by the Company or a Restricted Subsidiary (other than Capital Stock or Indebtedness Incurred as consideration in, or to provide all or any portion of the funds utilized to consummate, the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company or in contemplation of the transaction) and outstanding on such date provided, that any such encumbrance or restriction shall not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property so acquired and all improvements, additions and accessions thereto and products and proceeds thereof, and that, in the case of Indebtedness, was permitted to be Incurred pursuant to the Indenture;

(3) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement effecting a refunding, replacement or refinancing, in whole or in part, of Indebtedness Incurred pursuant to an agreement referred to in clause (1) or (2) of this Section 6.10(b) or this clause (3) or contained in any amendment, restatement, modification, renewal, supplement, refunding, replacement or refinancing of an agreement referred to in clause (1) or (2) of this Section 6.10(b) or this clause (3); provided, however, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement are not materially less favorable, taken as a whole, to the Holders of the Notes than the encumbrances and restrictions contained in such agreements referred to in clauses (1) or (2) of this Section 6.10(b) on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was merged into a Restricted Subsidiary, whichever is applicable;

(13) restrictions on the transfer of property or assets required by any regulatory authority having jurisdiction over the Company or any Restricted Subsidiary or any of their businesses.

SECTION 6.11 Limitation on Sales of Assets and Subsidiary Stock

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at least equal to the fair market value (such fair market value to be determined on the date of contractually agreeing to such Asset Disposition), as determined in good faith by the Board of Directors (including as to the value of all non-cash consideration), of the shares and assets subject to such Asset Disposition;

(2) at least 75% of the consideration from such Asset Disposition received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; and

(3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company or such Restricted Subsidiary, as the case may be:

(A) to the extent the Company or any Restricted Subsidiary, as the case may be, elects or is required to do so, to prepay, repay, redeem, defease or purchase Indebtedness of the Company or a Restricted Subsidiary (other than Capital Stock, Disqualified Stock, Subordinated Obligations, Guarantor Subordinated Obligations or Indebtedness owed to the Company or an Affiliate of the Company) within 330 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; provided, however, that, in connection with any prepayment, repayment, redemption, defeasance or purchase of Indebtedness pursuant to this clause (3)(A), the Company or such Restricted Subsidiary shall retire such Indebtedness and shall cause the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed, defeased or purchased; and

(B) to the extent the Company or such Restricted Subsidiary elects, to invest in Additional Assets within 330 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash;

provided that pending the final application of any such Net Available Cash in accordance with clause (3)(A) or clause (3)(B) of this Section 6.11(a), the Company and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by the Indenture.

Any Net Available Cash from Asset Dispositions that is not applied or invested as provided in the preceding paragraph shall be deemed to constitute “Excess Proceeds.” On the 331st day after an Asset Disposition, if the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company shall be required to (and may, in satisfaction of such requirement, at any time prior to such day) make an offer (an “Asset Disposition Offer”) to all Holders of Notes and to the extent required by the terms of other Pari Passu Indebtedness, to all Holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Company to make an offer

to purchase such Pari Passu Indebtedness with the proceeds from any Asset Disposition (“Pari Passu Notes”), to purchase the maximum principal amount of Notes and any such Pari Passu Notes to which the Asset Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes and Pari Passu Notes plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in the Indenture or the agreements governing the Pari Passu Notes, as applicable, in each case in denominations of $2,000 and larger integral multiples of $1,000. To the extent that the aggregate amount of Notes and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof and other Pari Passu Notes surrendered by Holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and Pari Passu Notes to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes and Pari Passu Notes. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

(b) The Asset Disposition Offer shall remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five Business Days after the termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the Company shall purchase the principal amount of Notes and Pari Passu Notes required to be purchased pursuant to this Section 6.11 (the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Notes and Pari Passu Notes validly tendered in response to the Asset Disposition Offer.

If the Asset Disposition Purchase Date is on or after a Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such Regular Record Date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Disposition Offer.

On or before the Asset Disposition Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Notes and Pari Passu Notes or portions of Notes and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Notes so validly tendered and not properly withdrawn, in each case in integral multiples of $1,000. The Company shall deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 6.11 and, in addition, the Company shall deliver all certificates and notes required, if any, by the agreements governing the Pari Passu Notes. The Company or the Paying Agent, as the case may be, shall promptly (but in any case not later than five Business Days after the termination of the Asset Disposition Offer Period) mail or deliver to each tendering Holder of Notes or Holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Notes or Pari Passu Notes so validly tendered and not properly withdrawn by such Holder or lender, as the case may be, and accepted by the Company

for purchase, and the Company shall promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Company, shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note shall be in a principal amount of $2,000 or a larger integral multiple of $1,000. In addition, the Company shall take any and all other actions required by the agreements governing the Pari Passu Notes. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date.

(c) For the purposes of clause (2) of Section 6.11(a) of this Second Supplemental Indenture only, the following shall be deemed to be cash:

Within 30 days following any Change of Control, unless the Company has given irrevocable notice that it shall exercise its right to redeem all of the Notes pursuant to Section 7.05 of this Second Supplemental Indenture, the Company shall mail a notice (the “Change of Control Offer”) to each Holder, with a copy to the Trustee, stating:

(1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant interest payment date) (the “Change of Control Payment”);

(3) the procedures determined by the Company, consistent with the Indenture, that a Holder must follow in order to have its Notes repurchased.

On the Change of Control Payment Date, the Company shall, to the extent lawful:

(1) accept for payment all Notes or portions of Notes (of $2,000 or larger integral multiples of $1,000) properly tendered pursuant to the Change of Control Offer;

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

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

The Paying Agent shall promptly mail (or cause to be transferred by book entry) to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note shall be in a principal amount of $2,000 or larger integral multiples of $1,000.

The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this Section 6.14.

In the event that the Company is not permitted to file such reports, documents and information with the Commission pursuant to the Exchange Act, the Company shall nevertheless make available such Exchange Act information to the Trustee and the Holders of the Notes as if the Company were subject to the reporting requirements of Section 13 or 15(d) of the Exchange

Act, in each case not later than 60 days after the final due dates therefor specified therein or in the relevant forms (after giving effect to any cure period specified therein). For the avoidance of doubt, no Default shall be deemed to occur under the Indenture with respect to the Notes until the expiration of such 60-day period.

If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by this Section 6.15 shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes to the financial statements and in Management’s Discussion and Analysis of Results of Operations and Financial Condition, of the financial condition and results of operations of the Company and its Restricted Subsidiaries.

In the event that any direct or indirect parent company of the Company becomes a guarantor of the Notes, the Company may satisfy its obligations under this Section 6.15 by furnishing financial information relating to such parent; provided that (a) such financial statements are accompanied by consolidating financial information for such parent, the Company, the Subsidiary Guarantors and the Subsidiaries of the Company that are not Subsidiary Guarantors in the manner prescribed by the Commission and (b) such parent is not engaged in any business in any material respect other than incidental to its ownership, directly or indirectly, of the Capital Stock of the Company.

Pursuant to Section 3.02(5)(a) of this Second Supplemental Indenture, a Default under this Section 6.15 is subject to a 180-day cure period. During such cure period, the interest rate on the Notes shall increase by the Additional Interest.

SECTION 6.16 Future Subsidiary Guarantors

After the Issue Date, the Company shall cause each Restricted Subsidiary (other than a Foreign Subsidiary) that Guarantees any Indebtedness of the Company or any Subsidiary Guarantor to execute and deliver to the Trustee a Subsidiary Guarantee pursuant to which such Subsidiary Guarantor shall unconditionally Guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any and interest on the Notes on a senior basis.

Notice of redemption having been given as aforesaid, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Notes shall cease to bear interest.

SECTION 8.02 Discharge of Liability on Notes; Defeasance

(a) Subject to Sections 8.02(b) and 8.03 of this Second Supplemental Indenture, the Company at any time may terminate (i) all its obligations under the Notes and the Indenture and all obligations of the Subsidiary Guarantors under the Subsidiary Guarantees and the Indenture (“legal defeasance”), and after giving effect to such legal defeasance, any omission to comply with such obligations shall no longer constitute a Default or Event of Default or (ii) its obligations under clause (3) of Section 4.02 of this Second Supplemental Indenture and Sections 6.06, 6.07, 6.08, 6.09, 6.10, 6.11, 6.12, 6.13, 6.14, 6.15, or 6.16 of this Second Supplemental Indenture and Section 1006 of the Original Indenture and the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply with such covenants shall no longer constitute a Default or an Event of Default under clauses (3), (4) and (5) of Section 3.02 of this Second Supplemental Indenture and the operation of clauses (6), (7) (but only with respect to a Significant Subsidiary or group of Restricted Subsidiaries that would constitute a Significant Subsidiary), (8) and (9) of Section 3.02 of this Second Supplemental Indenture, and the events specified in such Sections shall no longer constitute an Event of Default (clause (ii) being referred to as the “covenant defeasance”), but except as specified above, the remainder of the Indenture and the Notes shall be unaffected thereby. The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

Thereafter, the Company’s obligations in Sections 607 of the Original Indenture and Sections 8.04, 8.06 and 8.07 of this Second Supplemental Indenture shall survive.

SECTION 8.03 Conditions to Defeasance

The Company may exercise its legal defeasance option or its covenant defeasance option only if:

(d) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a Default under, the Indenture or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(e) the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) to the effect that, assuming no intervening bankruptcy of the Company between the date of deposit and the 123rd day following the deposit and that no Holder of the Notes is an insider of the Company within the meaning of the Bankruptcy Law, after the 123rd day following the deposit, the trust funds shall not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ right generally;

(f) the Company delivers to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940;

SECTION 8.05 Repayment to Company

The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money, U.S. Government Obligations or securities held by them upon payment of all the obligations under the Indenture.

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal of or interest on the Notes that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Company for payment as general creditors.

SECTION 8.06 Indemnity for U.S. Government Obligations

The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article Eight by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company and the Subsidiary Guarantors under the Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eight until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this

Article Eight; provided, however, that, if the Company has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE NINE
SUBSIDIARY GUARANTEE

SECTION 9.01 Subsidiary Guarantee

Each Subsidiary Guarantor hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Subsidiary Guarantor, to each Holder of the Notes and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Notes and all other monetary obligations of the Company under the Indenture (all the foregoing being hereinafter collectively called the “Obligations”). Each Subsidiary Guarantor further agrees (to the extent permitted by law) that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it shall remain bound under this Article Nine notwithstanding any extension or renewal of any Obligation.

Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Notes or the Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under the Indenture, the 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 the Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder to exercise any right or remedy against any other Subsidiary Guarantor; or (f) any change in the ownership of the Company.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a Guarantee of payment when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Obligations.

Except as expressly set forth in Sections 8.02(a), 9.02 and 9.03 of this Second Supplemental Indenture, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), 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 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 to assert any claim or demand or to enforce any remedy under the Indenture, the 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 any Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee 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 of the Obligations is rescinded or must otherwise be restored by any Holder 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 has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, 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 an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest on such Obligations then due and owing (but only to the extent not prohibited by law) and except as provided in Section 9.03 of this Second Supplemental Indenture.

Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in the Indenture for the purposes of its Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the purposes of this Subsidiary Guarantee.

Each Subsidiary Guarantor also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing any rights under this Section 9.01.

SECTION 9.02 Termination, Release and Discharge

(a) Subject to Section 6.11 and Article Four of this Second Supplemental Indenture, each Subsidiary Guarantor may consolidate with or merge into or sell all or substantially all of its property and assets to the Company, another Subsidiary Guarantor or a Person other than the Company or another Subsidiary Guarantor (whether or not Affiliated with the Subsidiary Guarantor).

(b) Notwithstanding the foregoing and the other provisions of the Indenture, in the event a Subsidiary Guarantor is sold or disposed of (whether by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its assets (other than by lease) and whether or not the Subsidiary Guarantor is the surviving corporation in such transaction) to a Person which is not the Company or a Restricted Subsidiary, such Subsidiary Guarantor shall be released from its obligations under its Subsidiary Guarantee if:

(1) the sale or other disposition is in compliance with the Indenture, including Section 6.11 of this Second Supplemental Indenture (it being understood that only such portion of the Net Available Cash as is required to be applied on or before the date of such release in accordance with the terms of the Indenture needs to be applied in accordance therewith at such time), Section 6.13 and Article Four of this Second Supplemental Indenture; and

(2) all the obligations of such Subsidiary Guarantor under all Indebtedness of the Company and all Subsidiary Guarantors terminate upon consummation of such transaction.

(c) A Subsidiary Guarantor shall be deemed released and relieved of its obligations under the Indenture and its Subsidiary Guarantee without any further action required on the part of the Company or such Subsidiary Guarantor upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of the Indenture or in connection with any legal defeasance of the Notes or upon satisfaction and discharge of the Indenture, each in accordance with the provisions of the Indenture.

SECTION 9.03 Limitation of Subsidiary Guarantors’ Liability

Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of each Subsidiary Guarantor shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including, without limitation, any guarantees under the Senior Credit Facility) and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to Section 9.04 of this Second Supplemental Indenture, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or state law. This Section 9.03 is for the benefit of the creditors of each Subsidiary Guarantor.

SECTION 9.04 Contribution

In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, that in the event any payment or distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under its Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor (if any) in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Notes or any other Subsidiary Guarantor’s obligations with respect to its Subsidiary Guarantee.
