2

from the proved oil and gas reserves of the Issuer and its Restricted Subsidiaries as so calculated due 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, provided, that (x) in the case of such year end reserve report and any adjustments since such year end pursuant to clauses (A), (B) and (D), the estimated discounted future net revenues from proved oil and gas reserves shall be determined in their entirety using oil, gas and other hydrocarbon prices and costs that are either (1) calculated in accordance with SEC guidelines and, with respect to such adjustments under clauses (A), (B) or (D), calculated with such prices and costs as if the end of the most recent fiscal quarter preceding the date of determination for which such information is available to the Issuer were year end or (2) if the Issuer so elects at any time, calculated in accordance with the foregoing clause (1), except that when pricing of future net revenues of proved oil and gas reserves under SEC guidelines is not based on a contract price and is instead based upon benchmark, market or posted pricing, the pricing for each month of estimated future production from such proved oil and gas reserves not subject to contract pricing shall be based upon NYMEX (or successor) published forward prices for the most comparable hydrocarbon commodity applicable to such production month (adjusted for energy content, quality and basis differentials, with such basis differentials determined in a manner consistent with the determination of the Borrowing Base and giving application to the last sentence of such definition hereto), as such forward prices are published as of the year end date of such reserve report or, with respect to post-year end adjustments under clauses (A), (B) or (D), the last day of the most recent fiscal quarter preceding the date of determination, (y) the pricing of estimated proved reserves that have been produced or disposed since year end as set forth in clause (D) shall be based upon the applicable pricing elected for the prior year end reserve report as provided in clause (x), and (z) in each of cases (A), (B), (C) and (D) as estimated by the Issuer’s petroleum engineers or any independent petroleum engineers engaged by the Issuer for that purpose;

(iii) the Net Working Capital on a date no earlier than the date of the Issuer’s latest annual or quarterly consolidated financial statements;

assets (including, without limitation, investments in unconsolidated Restricted Subsidiaries and mineral rights held under lease or other contractual arrangement) of the Issuer and its Restricted Subsidiaries, as of a date no earlier than the date of the Issuer’s latest audited consolidated financial statements (it being understood that the Issuer shall not be required to obtain any appraisal of any assets); minus

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

If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into the Issuer or any Restricted Subsidiary since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation, amalgamation, discontinued operation or operational change, in each case with respect to an operating unit of a business, that would have required adjustment pursuant to this definition, then the Consolidated Leverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, discontinued operation, merger, amalgamation, consolidation or operational change had occurred at the beginning of the applicable four-quarter period. If since the beginning of such period any Restricted Subsidiary is designated an Unrestricted Subsidiary or any Unrestricted Subsidiary is designated a Restricted Subsidiary, then the Consolidated Leverage Ratio shall be calculated giving pro forma effect thereto for such period as if such designation had occurred at the beginning of the applicable four-quarter period.

13

For purposes of this definition, whenever pro forma effect is to be given to any event, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of the Issuer. Any such pro forma calculation may include adjustments appropriate, in the reasonable good faith determination of the Issuer as set forth in an Officers’ Certificate, to reflect operating expense reductions and other operating improvements or synergies reasonably expected to result from the applicable event on or prior to the date that is 12 months after such applicable event; provided that the aggregate amount of operating expense reductions and other operating improvements or synergies added to EBITDA pursuant to this paragraph or the third paragraph of the definition of Fixed Charge Coverage Ratio, plus the aggregate amount of cash items excluded and resulting in an increase to Consolidated Net Income pursuant to clause (1) in the definition of Consolidated Net Income, plus the aggregate amount of cash items added back to EBITDA pursuant to clause (6) in the definition of EBITDA, shall not exceed, in any applicable four quarter period, the Aggregate Special Cap.

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 Leverage Ratio Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuer may designate.

For purposes of this definition, any amount in a currency other than U.S. dollars will be converted to U.S. dollars based on the average exchange rate for such currency for the most recent twelve-month period immediately prior to the date of determination in a manner consistent with that used in calculating EBITDA for the applicable period.

(8) solely for the purpose of determining the amount available for Restricted Payments under clause (1) of the definition of “Cumulative Credit,” the Net Income for such period of any Restricted Subsidiary (other than any Subsidiary Guarantor) shall be excluded to the extent that the declaration or payment of dividends or similar distributions by such Restricted Subsidiary of its Net Income is not at the date of determination permitted without any prior governmental approval (which has not been obtained) or, directly or indirectly, by the operation of the terms of its charter or any agreement, instrument, judgment, decree, order, statute, rule or governmental regulation applicable to that Restricted Subsidiary or its stockholders, unless such restrictions with respect to the payment of dividends or similar distributions have been legally waived; provided that the Consolidated Net Income of such Person shall be increased by the amount of dividends or other distributions or other payments actually paid in cash (or converted into cash) by any such Restricted Subsidiary to such Person, to the extent not already included therein;

(9) an amount equal to the amount of Tax Distributions actually made to any parent or equity holder of such Person in respect of such period in accordance with Section 4.04(b)(xii) shall be included as though such amounts had been paid as income taxes directly by such Person for such period;

Notwithstanding the foregoing, for the purpose of Section 4.04 only, there shall be excluded from Consolidated Net Income any dividends, repayments of loans or advances or other transfers of assets from Unrestricted Subsidiaries or Restricted Subsidiaries to the extent such dividends, repayments or transfers increase the amount of Restricted Payments permitted under Section 4.04 pursuant to clauses (4) and (5) of the definition of “Cumulative Credit.”

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 Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuer may designate.

For purposes of this definition, any amount in a currency other than U.S. dollars will be converted to U.S. dollars based on the average exchange rate for such currency for the most recent twelve month period immediately prior to the date of determination in a manner consistent with that used in calculating EBITDA for the applicable period.

provisions will not be deemed to have been exceeded (or, with respect to the Fixed Charge Coverage Ratio, not reached) as a result of such fluctuations solely for purposes of determining whether the Limited Condition Transaction is permitted hereunder and (y) such ratio and other provisions shall not be tested at the time of consummation of such Limited Condition Transaction or related Specified Transactions. If the Issuer has made an LCT Election for any Limited Condition Transaction, then in connection with any subsequent calculation of any ratio or basket availability with respect to any other Specified Transaction on or following the relevant LCT Test Date and prior to the earlier of the date on which such Limited Condition Transaction is consummated or the date that the definitive agreements for such Limited Condition Transaction are terminated or expire without consummation of such Limited Condition Transaction, any such ratio or basket shall be calculated on a pro forma basis assuming such Limited Condition Transaction and other Specified Transactions in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof) have been consummated until such time as the applicable Limited Condition Transaction has actually closed or the definitive agreements with respect thereto have been terminated or expire. Notwithstanding the foregoing, the Issuer may at any time withdraw any LCT Election, in which case any Indebtedness and Liens incurred in reliance on such LCT Election in accordance with the foregoing outstanding at such time, if any, shall be deemed to be incurred on the date of such withdrawal.

SECTION 1.05 Trust Indenture Act. This Indenture is not subject to the TIA except as expressly stated herein. Whenever this Indenture refers to a provision of the TIA, the provision is incorporated by reference in and made a part of this Indenture.

ARTICLE II

THE NOTES

SECTION 2.01 Amount of Notes. The aggregate principal amount of Notes which may be authenticated and delivered under this Indenture on the Issue Date is $625,000,000.

The Issuer may from time to time after the Issue Date issue Additional Notes under this Indenture in an unlimited principal amount, so long as (i) the Incurrence of the Indebtedness represented by such Additional Notes is at such time permitted by Section 4.03 and the Liens with respect thereto are permitted by Section 4.11 and (ii) such Additional Notes are issued in compliance with the other applicable provisions of this Indenture. With respect to any Additional Notes issued after the Issue Date (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section 2.07, 2.08, 2.09, 3.08, 4.06(g), 4.08(c) or Appendix A), there shall be (a) established in or pursuant to a resolution of the Board of Directors of the Issuer and (b) (i) set forth or determined in the manner provided in an Officers’ Certificate or (ii) established in one or more indentures supplemental hereto, prior to the issuance of such Additional Notes:

(1) the aggregate principal amount of such Additional Notes which may be authenticated and delivered under this Indenture;

52

(2) the issue price and issuance date of such Additional Notes, including the date from which interest on such Additional Notes shall accrue;

(3) if applicable, that such Additional Notes shall be issuable in whole or in part in the form of one or more Global Notes and, in such case, the respective depositaries for such Global Notes, the form of any legend or legends which shall be borne by such Global Notes in addition to or in lieu of those set forth in Exhibit A hereto and any circumstances in addition to or in lieu of those set forth in Section 2.2 of Appendix A in which any such Global Note may be exchanged in whole or in part for Additional Notes registered, or any transfer of such Global Note in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Note or a nominee thereof; and

(4) if applicable, that such Additional Notes that are not Transfer Restricted Notes shall not be issued in the form of Initial Notes as set forth in Exhibit A hereto.

If any of the terms of any Additional Notes are established by action taken pursuant to a resolution of the Board of Directors of the Issuer, a copy of an appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of the Issuer and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or an indenture supplemental hereto setting forth the terms of the Additional Notes.

The Initial Notes and any Additional Notes may, at the Issuer’s option, be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided that if the Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, the Additional Notes will have a separate CUSIP number, if applicable.

SECTION 2.02 Form and Dating. Provisions relating to the Notes are set forth in Appendix A, which is hereby incorporated in and expressly made a part of this Indenture. The (i) Initial Notes and the Trustee’s certificate of authentication and (ii) any Additional Notes and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Subsidiary Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer). Each Note shall be dated the date of its authentication. The Notes shall be issuable only in registered form without interest coupons and in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof, provided that Notes may be issued in denominations of less than $2,000 solely to accommodate book-entry positions that have been created by participants of the Depository in denominations of less than $2,000.

SECTION 2.03 Execution and Authentication. The Trustee shall authenticate and make available for delivery upon a written order of the Issuer signed by one Authorized Officer of the Issuer (a) Initial Notes for original issue on the date hereof in an aggregate principal amount of $625,000,000 and (b) subject to the terms of this Indenture, Additional Notes in an aggregate principal amount to be determined at the time of issuance and

53

specified therein. Such order shall specify the amount of separate Note certificates to be authenticated, the principal amount of each of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated, whether the Notes are to be Initial Notes or Additional Notes, the registered holder of each of the Notes and delivery instructions. Notwithstanding anything to the contrary in this Indenture or Appendix A, any issuance of Additional Notes after the Issue Date shall be in a principal amount of at least $2,000 and in integral multiples of $1,000 in excess thereof.

One Authorized Officer shall sign the Notes for the Issuer by manual, electronic, facsimile signature or electronically transmitted signature (including .pdf).

If an Authorized Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note, the Note shall be valid nevertheless.

A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee may appoint one or more authenticating agents reasonably acceptable to the Issuer to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.04 Registrar and Paying Agent.

(a) The Issuer shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) an office or agency where Notes may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuer may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Issuer initially appoints the Trustee as Registrar, Paying Agent and the Notes Custodian with respect to the Global Notes.

(b) The Issuer may enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee in writing of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Issuer or any of its domestically organized Subsidiaries may act as Paying Agent or Registrar.

54

(c) The Issuer may remove any Registrar or Paying Agent upon five Business Days’ prior written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor Registrar or Paying Agent, as the case may be, as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Issuer and the Trustee; provided, however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08.

SECTION 2.05 Paying Agent to Hold Money in Trust. Prior to or on each due date of the principal of and interest on any Note, the Issuer shall deposit with each Paying Agent (or if the Issuer or a Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying Agent shall hold in trust for the benefit of holders or the Trustee all money held by a Paying Agent for the payment of principal of and interest on the Notes, and shall notify the Trustee in writing of any default by the Issuer in making any such payment. If the Issuer or a Subsidiary of the Issuer acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it in trust for the benefit of the Persons entitled thereto. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.05, a Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.06 Holder Lists. The Registrar shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of holders. If the Trustee is not the Registrar, the Issuer shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of holders.

SECTION 2.07 Transfer and Exchange. The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer and in compliance with Appendix A. When a Note is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if its requirements therefor are met. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Notes at the Registrar’s request. The Issuer may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section 2.07. The Issuer shall not be required to make, and the Registrar need not register, transfers or exchanges of Notes selected for redemption (except, in the case of Notes to be redeemed in part, the portion thereof not to be redeemed) or of any Notes for a period of 15 days before a selection of Notes to be redeemed or between a record date and the related interest payment date.

55

Prior to the due presentation for registration of transfer of any Note, the Issuer, the Subsidiary Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest, if any, on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Issuer, the Subsidiary Guarantors, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

Any holder of a beneficial interest in a Global Note shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by (a) the holder of such Global Note (or its agent) or (b) any holder of a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry.

All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depository participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

None of the Trustee, Registrar or Paying Agent shall have any responsibility for any actions taken or not taken by the Depository.

SECTION 2.08 Replacement Notes. If a mutilated Note is surrendered to the Registrar or if the holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the holder (a) satisfies any requirement of the Issuer and the Trustee within a reasonable time after such holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuer and the Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Issuer and the Trustee. If required by the Trustee or the Issuer, such holder shall furnish an indemnity bond sufficient in the judgment of the Trustee, with respect to the Trustee, and the Issuer, with respect to the Issuer, to protect the Issuer, the Trustee, the Paying Agent and the Registrar, as applicable, from any loss or liability that any of them may suffer if a Note is replaced and subsequently presented or claimed for payment. The Issuer and the Trustee may charge the holder for their expenses in replacing a Note (including, without limitation, attorneys’ fees and disbursements in replacing such Note). In the event any such mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Issuer in its discretion may pay such Note instead of issuing a new Note in replacement thereof.

56

Every replacement Note is an additional obligation of the Issuer.

The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes.

SECTION 2.09 Outstanding Notes. Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.09 as not outstanding. Subject to Section 13.06, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.08 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.08.

If a Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is prohibited from paying such money to the holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10 Cancellation. The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and each Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Notes in accordance with its customary procedures. The Issuer may not issue new Notes to replace Notes they have redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Notes in place of canceled Notes other than pursuant to the terms of this Indenture.

SECTION 2.11 Defaulted Interest. If the Issuer defaults in a payment of interest on the Notes, the Issuer shall pay the defaulted interest then borne by the Notes (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Issuer may pay the defaulted interest to the Persons who are holders on a subsequent special record date. The Issuer shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly deliver or cause to be delivered to each affected holder (with a copy to the Trustee) a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

SECTION 2.12 CUSIP Numbers, ISINs, Etc. The Issuer in issuing the Notes may use CUSIP numbers, ISINs and “Common Code” numbers (if then generally in use), and the Trustee shall use any such CUSIP numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to holders; provided, however, that any such notice may

57

state that no representation is made as to the correctness of such numbers, either as printed on the Notes or as contained in any notice of redemption, that reliance may be placed only on the other identification numbers printed on the Notes and that any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer shall advise the Trustee in writing of any change in any such CUSIP numbers, ISINs and “Common Code” numbers.

SECTION 2.13 Calculation of Principal Amount of Notes. The aggregate principal amount of the Notes, at any date of determination, shall be the principal amount of the Notes at such date of determination. With respect to any matter requiring consent, waiver, approval or other action of the holders of a specified percentage of the principal amount of all the Notes, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Notes, the holders of which have so consented, by (b) the aggregate principal amount, as of such date of determination, of the Notes then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.09 and Section 13.06 of this Indenture. Any calculation of the Applicable Premium made pursuant to this Indenture or the Notes shall be made by the Issuer and delivered to the Trustee pursuant to an Officers’ Certificate. The Trustee shall have no liability or responsibility for any calculation made hereunder or in connection herewith or for any information used in any such calculation.

ARTICLE III

REDEMPTION

SECTION 3.01 Redemption. The Notes may be redeemed, in whole or from time to time in part, subject to the conditions and at the redemption prices set forth in Paragraphs 5 and 6, as applicable, of the form of Note set forth in Exhibit A hereto, which is hereby incorporated by reference and made a part of this Indenture, together with accrued and unpaid interest, if any, to, but excluding, 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).

SECTION 3.02 Applicability of Article. Redemption of Notes at the election of the Issuer or otherwise, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article III.

SECTION 3.03 Notices to Trustee. If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Paragraph 5 of the Note, the Issuer shall deliver to the Trustee in an Officers’ Certificate that states (i) the Section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price. The Issuer shall give notice to the Trustee provided for in this paragraph at least 10 days but not more than 60 days before a redemption date if the redemption is a redemption pursuant to Paragraph 5 of the Note. The Issuer may also include a request in such Officers’ Certificate that the Trustee give the notice of redemption in the Issuer’s name and at its expense and setting forth the information to be stated in such notice as provided in Section 3.05. Any such notice may be canceled if written notice from the Issuer of such cancellation is actually received by the Trustee prior to notice of such redemption being mailed to any holder or otherwise delivered in accordance with the applicable procedures of the Depository and shall thereby be void and of no effect. The Issuer shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 3.04.

58

SECTION 3.04 Selection of Notes to Be Redeemed. In the case of any partial redemption, selection of the Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed (and the Issuer shall notify the Trustee in writing of any such listing), or if the Notes are not so listed, on a pro rata basis to the extent practicable or by lot or by such other method as the Trustee shall deem fair and appropriate (and, in each case, in such manner that complies with the requirements of the Depository, if applicable); provided that no Notes of $2,000 or less shall be redeemed in part. The Trustee shall make the selection from outstanding Notes not previously called for redemption. The Trustee may select for redemption portions of the principal of Notes that have denominations larger than $2,000. Notes and portions of them the Trustee selects shall be in amounts of $2,000 or integral multiples of $1,000 in excess thereof. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. Upon selection, the Trustee shall notify the Issuer promptly of the Notes or portions of Notes to be redeemed.

SECTION 3.05 Notice of Redemption.

(a) At least 10 but not more than 60 days before a redemption date pursuant to Paragraph 5 of the Note (other than such notice given in connection with a Special Mandatory Redemption, which shall be given pursuant to Section 3.09), the Issuer shall mail or cause to be mailed by first-class mail at its registered address, or otherwise deliver in accordance with the procedures of the Depository, a notice of redemption to each holder whose Notes are to be redeemed (with a copy to the Trustee), except that redemption notices may be mailed or otherwise delivered more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article VIII.

Any such notice shall identify the Notes to be redeemed and shall state:

(i) the redemption date;

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

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

(iv) that Notes called for redemption must be surrendered to the Trustee or Paying Agent to collect the redemption price, plus accrued and unpaid interest, if any;

(v) if fewer than all the outstanding Notes are to be redeemed, the certificate numbers and principal amounts of the particular Notes to be redeemed, the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption;

59

(vi) that, unless the Issuer defaults in making such redemption payment or the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Notes (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

(vii) the CUSIP number, ISIN and/or “Common Code” number, if any, printed on the Notes being redeemed;

(viii) that no representation is made as to the correctness or accuracy of the CUSIP number or ISIN and/or “Common Code” number, if any, listed in such notice or printed on the Notes;

(ix) if the redemption is subject to the satisfaction of one or more conditions precedent, the notice thereof shall describe each such condition and, if applicable, shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed; and

(x) at the Issuer’s option, that the payment of the redemption price and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

Notice of any redemption upon any corporate transaction or other event (including any Equity Offering, incurrence of Indebtedness, Change of Control or other transaction) may be given prior to the completion thereof. In addition, any redemption or notice thereof may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction or other event.

(b) At the Issuer’s request, the Trustee shall deliver the notice of redemption in the Issuer’s name and at the Issuer’s expense subject to the terms of Section 3.03 hereof. In such event, the Issuer shall notify the Trustee of such request at least three Business Days (or such shorter period as is acceptable to the Trustee) prior to the date such notice is to be provided to holders.

SECTION 3.06 Effect of Notice of Redemption. Once notice of redemption is mailed or otherwise delivered in accordance with Section 3.05, Notes called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, except as provided in the final paragraph of Paragraph 5 of the Notes or Section 3.05(a). Upon surrender to the Paying Agent, such Notes shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest, if any, to, but excluding, the redemption date; provided, however, that if the redemption date is after a regular Record Date and on or prior to the next Interest Payment Date, the accrued interest shall be payable to the holder of the redeemed Notes registered on the relevant Record Date. Failure to give notice or any defect in the notice to any holder shall not affect the validity of the notice to any other holder.

60

SECTION 3.07 Deposit of Redemption Price. With respect to any Notes, prior to 10:00 a.m., New York City time, on the redemption date, the Issuer shall deposit with the Paying Agent (or, if the Issuer or a Subsidiary of the Issuer is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued and unpaid interest, if any, on all Notes or portions thereof to be redeemed on that date other than Notes or portions of Notes called for redemption that have been delivered by the Issuer to the Trustee for cancellation. On and after the redemption date, interest shall cease to accrue on Notes or portions thereof called for redemption so long as the Issuer has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest, if any, on, the Notes or portions thereof to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture.

SECTION 3.08 Notes Redeemed in Part. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. Upon surrender and cancellation of a Note that is redeemed in part, the Issuer shall execute and the Trustee shall authenticate for the holder (at the Issuer’s expense) a new Note equal in principal amount to the unredeemed portion of the Note surrendered and cancelled.

SECTION 3.09 Special Mandatory Redemption. If (1) the consummation of the QuarterNorth Acquisition does not occur on or before May 31, 2024 (as may be extended up to September 30, 2024 solely in the event the parties to the Merger Agreement require additional time to satisfy certain requirements under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, the “Outside Date”) or (2) the Issuer delivers a notice to the Trustee in writing that the Parent Guarantor will not pursue the consummation of the QuarterNorth Acquisition (the earlier of the date of the delivery of such notice and the Outside Date, the “Special Mandatory Redemption Trigger Date”), the Issuer will be required to redeem $340.0 million aggregate principal amount of the Notes and the 2029 Notes then outstanding, on a pro rata basis (the “Special Mandatory Redemption”), at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the Notes being redeemed, if any, to, but excluding, the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”). In the event that the Issuer becomes obligated to redeem the Notes pursuant to the Special Mandatory Redemption, the Issuer will promptly, and in any event not more than 10 Business Days after the Special Mandatory Redemption Trigger Date, deliver notice to the Trustee of the Special Mandatory Redemption and the date upon which such Notes will be redeemed (the “Special Mandatory Redemption Date”), which date shall be no later than the third Business Day following the date of such notice, together with a notice of Special Mandatory Redemption and written instructions to the Trustee instructing the Trustee to deliver such notice to each registered holder of Notes to be redeemed. The Trustee will then promptly mail, or deliver electronically if the Notes are held by any depositary (including, without limitation, the Depository) in accordance with such depositary’s customary procedures, such notice of Special Mandatory Redemption to each holder of Notes to be redeemed at its registered address. Unless the Issuer defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the Notes to be redeemed.

COVENANTS

SECTION 4.01 Payment of Notes. The Issuer shall promptly pay the principal of and interest on the Notes on the dates and in the manner provided in the Notes and in this Indenture. An installment of principal of or interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds as of 11:00 a.m. New York City time money sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the holders on that date pursuant to the terms of this Indenture.

The Issuer 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 borne by the Notes to the extent lawful.

(i) within the time period specified in the SEC’s rules and regulations for non-accelerated filers, annual reports on Form 10-K (or any successor or comparable form) containing the information that would have been required to be contained therein (or required in such successor or comparable form) if the Issuer were subject to Section 13 or 15(d) of the Exchange Act, except to the extent permitted to be excluded by the SEC;

(ii) within the time period specified in the SEC’s rules and regulations for non-accelerated filers, reports on Form 10-Q (or any successor or comparable form) containing the information that would have been required to be contained therein (or required in such successor or comparable form) if the Issuer were subject to Section 13 or 15(d) of the Exchange Act, except to the extent permitted to be excluded by the SEC; and

(iii) promptly from time to time after the occurrence of an event required to be therein reported (and in any event within the time period specified in the SEC’s rules and regulations), such other reports on Form 8-K (or any successor or comparable form) that would have been required if the Issuer were subject to Section 13 or 15(d) of the Exchange Act;

provided, however, that the Issuer shall not be so obligated to file such reports with the SEC if the SEC does not permit such filing, in which event the Issuer will make available such information to prospective purchasers of Notes in addition to providing such information to the Trustee and the holders, in each case within 15 days after the time the Issuer would be required to file such information with the SEC if it were subject to Section 13 or 15(d) of the Exchange Act.

If the Issuer has designated any of its Subsidiaries as an Unrestricted Subsidiary, then the annual and quarterly information required pursuant to clauses (i) and (ii) of this Section 4.02(a) shall include a reasonably detailed presentation, either on the face of the financial statements, in the footnotes thereto or in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of such Unrestricted Subsidiaries.

(b) In the event that:

(i) the rules and regulations of the SEC permit the Issuer and any direct or indirect parent of the Issuer (each, a “Reporting Entity”) to report at such parent entity’s level on a consolidated basis and such parent entity 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 Issuer, or

(ii) any direct or indirect parent of the Issuer is or becomes a Guarantor of the Notes,

consolidated reporting at such parent entity’s level in a manner consistent with that described in this Section 4.02 for the Issuer will satisfy this Section 4.02, and the Issuer is permitted to satisfy its obligations in this Section 4.02 with respect to financial information relating to the Issuer by furnishing financial information relating to such direct or indirect parent; provided that such financial information is accompanied by a reasonably detailed presentation, either on the face of the financial statements, in the footnotes thereto or in Management’s Discussion and Analysis of Financial Condition and Results of Operations, that explains the differences between the information relating to such direct or indirect parent and any of its Subsidiaries other than the Issuer and its Subsidiaries, on the one hand, and the information relating to the Issuer, the Subsidiary Guarantors and the other Subsidiaries of the Issuer on a standalone basis, on the other hand.

(c) The Issuer will make such information available to prospective investors upon request. The Issuer shall, for so long as any Notes remain outstanding during any period when neither it nor another Reporting Entity is subject to Section 13 or 15(d) of the Exchange Act, or otherwise permitted to furnish the SEC with certain information pursuant to Rule 12g3-2(b) of the Exchange Act, furnish to the holders of the Notes and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(d) Notwithstanding the foregoing, the Issuer will be deemed to have furnished the reports and information referred to in this Section 4.02 to the Trustee and the holders if the Issuer has filed such reports with the SEC via the EDGAR filing system (or any successor system) and such reports are publicly available. In addition, the requirements of this Section 4.02 shall be deemed satisfied by the posting of the reports and information that would be required to be filed with the SEC pursuant to Section 4.02(a) on a website or on IntraLinks or any comparable online data system or website. The Trustee shall have no obligation to monitor whether the Issuer posts such reports, information and documents on the SEC’s EDGAR filing system or any such online data system or website.

63

(e) The Issuer will also hold quarterly conference calls, beginning with the first full fiscal quarter ending after the Issue Date, for all holders of the Notes, prospective investors and securities analysts to discuss such financial information no later than 10 Business Days after the distribution of such information required by clauses (i) or (ii) of Section 4.02(a) and, prior to the date of each such conference call, will announce the time and date of such conference call and either include all information necessary to access the call or inform holders of the Notes, prospective investors and securities analysts how they can obtain such information, including, without limitation, the applicable password or login information (if applicable).

(f) The Trustee shall have no liability or responsibility for the content, filing or timeliness of any report delivered or filed under or in connection with this Indenture or the transactions contemplated hereby. Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.02 is for informational purposes only, and the Trustee’s receipt thereof shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

SECTION 4.03 Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.

(2) [reserved];

(3) if any Indebtedness denominated in U.S. dollars is exchanged, converted or refinanced into Indebtedness denominated in a foreign currency, then (in connection with such exchange, conversion or refinancing, and thereafter), the U.S. dollar amount limitations set forth in any of clauses (i) through (xxii) of Section 4.03(b) above with respect to such exchange, conversion or refinancing shall be deemed to be the amount of such foreign currency, as applicable, into which such Indebtedness has been exchanged, converted or refinanced at the time of such exchange, conversion or refinancing; and

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 in the determination of such amount of Indebtedness; provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in compliance with this Section 4.03.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness other than as provided in clauses (3) and (4) above, 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 debt, or first committed or first Incurred (whichever yields the lower U.S. dollar equivalent), in the case of revolving credit debt.

Notwithstanding any other provision of this Section 4.03, the maximum amount of Indebtedness that the Issuer and its Restricted Subsidiaries may Incur pursuant to this Section 4.03 shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate of currencies.

(i) any liabilities (as shown on the Issuer’s or a Restricted Subsidiary’s most recent balance sheet or in the notes thereto) of the Issuer or any Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets or that are otherwise cancelled or terminated in connection with the transaction with such transferee,

83

(ii) any notes or other obligations or other securities or assets received by the Issuer or such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received),

(v) [reserved], and

(vi) any Designated Non-cash Consideration received by the Issuer or any Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value (as determined in good faith by the Issuer), taken together with all other Designated Non-cash Consideration received pursuant to this clause (vi) that is at that time outstanding, not to exceed 5% of the Issuer’s Adjusted Consolidated Net Tangible Assets at the time of the receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value), shall be deemed to be Cash Equivalents for the purposes of this Section 4.06.

(b) Within 365 days of the Issuer’s or any Restricted Subsidiary’s receipt of the Net Proceeds of any Asset Sale, the Issuer or such Restricted Subsidiary may apply the Net Proceeds from such Asset Sale, at its option:

(i) to repay (v) Indebtedness constituting First-Priority Lien Obligations (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto), (w) Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor (provided that the assets disposed of in such Asset Sale were not assets of the Issuer or a Subsidiary Guarantor), (x) Obligations under the Notes, (y) other Pari Passu Indebtedness so long as the Net Proceeds from such Asset Sale are with respect to (A) assets that secure such other Pari Passu Indebtedness on a senior basis to the Notes Obligations or (B) assets not constituting Collateral or (z) Other Second-Lien Obligations (provided that if the Issuer or any Subsidiary Guarantor shall so reduce Other Second-Lien Obligations under this clause (z) (which for the avoidance of doubt will not constitute Indebtedness under clauses (v), (w), (x) or (y)), the Issuer will equally and ratably reduce Obligations under the Notes pursuant to Section 3.01, through open-market purchases (provided that such purchases are at or above 100% of the principal amount thereof or, in the event that the Notes were issued with significant original issue discount, 100% of the accreted value thereof) or by making an offer (in accordance with the procedures set forth below for an

84

Asset Sale Offer) to all holders to purchase at a purchase price equal to 100% of the principal amount thereof (or, in the event that the Notes were issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest, if any, the pro rata principal amount of Notes, in each case other than Indebtedness owed to the Issuer or an Affiliate of the Issuer);

(ii) to make an Investment in any one or more businesses (provided that if such Investment is in the form of the acquisition of Capital Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary of the Issuer), assets, or property or capital expenditures, in each case (x) used or useful in a Similar Business or (y) that replace the properties and assets that are the subject of such Asset Sale; provided that if the assets that were disposed of in the Asset Sale constituted Collateral, the assets acquired must also be Collateral; or

(iii) to invest in Additional Assets; provided that if the assets that were disposed of in the Asset Sale constituted Collateral, the Additional Assets must also be Collateral;

provided, that the requirement in clause (ii) or (iii) of this paragraph shall be deemed to be satisfied if a bona fide binding commitment to make the Investment or expenditure referred to therein is entered into by the Issuer or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Issuer within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such commitment within 180 days following the date such commitment is entered into.

(c) Any Net Proceeds from any Asset Sale that are not applied as provided and within the time period set forth in Section 4.06(b) (it being understood that any portion of such Net Proceeds used to make an offer to purchase Notes, as described in Section 4.06(b)(i), shall be deemed to have been invested whether or not such offer is accepted) will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $20.0 million, the Issuer shall make an offer to all holders of Notes (and, at the option of the Issuer, to holders of any Other Second-Lien Obligations) (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes (and such Other Second-Lien Obligations), that is at least $2,000 and an integral multiple of $1,000 in excess thereof 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 thereof (or, in the event the Notes or such Other Second-Lien Obligations were issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest, if any (or, in respect of such Other Second-Lien Obligations, such lesser price, if any, as may be provided for by the terms of such Other Second-Lien Obligations), to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Section 4.06. The Issuer will commence an Asset Sale Offer with respect to Excess Proceeds within 10 Business Days after the date that Excess Proceeds exceeds $20.0 million by delivering the notice required pursuant to the terms of Sections 3.05 and 4.06(f), with a copy to the Trustee. To the extent that the aggregate amount of Notes (and such Other Second-Lien Obligations) tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds for any purpose that is not prohibited by this Indenture. If the aggregate principal amount of Notes (and such Other Second-Lien Obligations) surrendered by holders thereof

85

exceeds the amount of Excess Proceeds, the Issuer, upon determination by the Issuer of the aggregate principal amount to be selected, shall select the Notes to be purchased in the manner described in Section 4.06(g). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(d) Pending the final application of any such Net Proceeds pursuant to this Section 4.06, the Issuer or such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture.

(e) The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

(f) Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as provided above, the Issuer shall deliver to the Trustee an Officers’ Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant to which such Asset Sale Offer is being made and (iii) the compliance of such allocation with the provisions of Section 4.06(b). On the Asset Sale Offer purchase date, the Issuer shall also irrevocably deposit with the Trustee or with a paying agent (or, if the Issuer or a Wholly Owned Restricted Subsidiary is acting as the Paying Agent, segregate and hold in trust) an amount equal to the Asset Sale Offer purchase price to be paid in accordance with the provisions of this Section 4.06. Upon the expiration of the period for which the Asset Sale Offer remains open (the “Asset Sale Offer Period”), the Issuer shall deliver to the Trustee for cancellation the Notes or portions thereof that have been properly tendered to and are to be accepted by the Issuer. The Trustee (or the Paying Agent, if not the Trustee) shall, on the date of purchase, mail or deliver payment to each tendering holder in the amount of the purchase price. In the event that the Excess Proceeds delivered by the Issuer to the Trustee are greater than the purchase price of the Notes tendered, the Trustee shall deliver the excess to the Issuer immediately after the expiration of the Asset Sale Offer Period for application in accordance with this Section 4.06.

(g) Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuer 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 Issuer receives not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered by the holder for purchase and a statement that such holder is withdrawing his election to have such Note purchased. If at the end of the Asset Sale Offer Period more Notes (and such Pari Passu Indebtedness) are tendered pursuant to an Asset Sale Offer than the Issuer is required to purchase, selection of such Notes for purchase shall be made by the Issuer in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed (and the Issuer shall notify the Trustee of any such listing), or if such Notes are not so listed, on a pro rata basis, to the

86

extent practicable, by lot or by such other method as the Issuer shall deem fair and appropriate (and in such manner as complies with the requirements of the Depository, if applicable); provided that no Notes of $2,000 or less shall be purchased in part. Selection of such Pari Passu Indebtedness shall be made pursuant to the terms of such Pari Passu Indebtedness.

(h) Notices of an Asset Sale Offer shall be mailed by the Issuer by first class mail, postage prepaid, or otherwise delivered in accordance with the applicable procedures of the Depository, at least 30 but not more than 60 days before the purchase date to each holder of Notes at such holder’s registered address (with a copy to the Trustee). If any Note is to be purchased in part only, any notice of purchase that relates to such Note shall state the portion of the principal amount thereof that has been or is to be purchased.

SECTION 4.07 Transactions with Affiliates.

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

(ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, the Issuer delivers to the Trustee an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (i) above; and

(vi) any agreement as in effect as of the Issue Date or any amendment thereto (so long as any such agreement together with all amendments thereto, taken as a whole, is not more disadvantageous to the holders of the Notes in any material respect than the original agreement as in effect on the Issue Date) or any transaction contemplated thereby as determined in good faith by the Issuer;

In the event that at the time of such Change of Control, the terms of the Bank Indebtedness restrict or prohibit the repurchase of Notes pursuant to this Section 4.08, then prior to the delivering of the notice to the holders provided for in Section 4.08(b) but in any event within 30 days following any Change of Control, the Issuer shall (i) repay in full all Bank Indebtedness or, if doing so will allow the purchase of Notes, offer to repay in full all Bank Indebtedness and repay the Bank Indebtedness of each lender and/or noteholder who has accepted such offer, or (ii) obtain the requisite consent under the agreements governing the Bank Indebtedness to permit the repurchase of the Notes as provided for in Section 4.08(b).

(b) Within 30 days following any Change of Control, except to the extent that the Issuer has exercised its right to redeem the Notes in accordance with Article III of this Indenture, the Issuer shall mail, or otherwise deliver in accordance with the applicable procedures of the Depository, a notice (a “Change of Control Offer”) to each holder with a copy to the Trustee stating:

(i) that a Change of Control has occurred and that such holder has the right to require the Issuer to repurchase such holder’s Notes at a repurchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of the holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date);

(ii) the circumstances and relevant facts and financial information regarding such Change of Control;

(iii) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is sent);

90

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

(v) that holders of Notes electing to have any Notes repurchased pursuant to a Change of Control Offer will be required to notify the Trustee prior to the close of business on the third Business Day preceding the Change of Control Offer Payment Date; and

(vi) the other instructions determined by the Issuer or as reasonably requested by the Trustee, consistent with this Section 4.08, that a holder must follow in order to have its Notes purchased.

(c) Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuer at the address specified in the notice at least three Business Days prior to the purchase date. The holders shall be entitled to withdraw their election if the Trustee or the Issuer receive not later than one Business Day prior to the purchase date a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered for purchase by the holder and a statement that such holder is withdrawing his election to have such Note purchased. Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

(d) On the purchase date, all Notes purchased by the Issuer under this Section 4.08 shall be delivered to the Trustee for cancellation, and the Issuer shall pay the purchase price, plus accrued and unpaid interest, if any, to the holders entitled thereto.

(e) A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

(f) Notwithstanding the foregoing provisions of this Section 4.08, the Issuer shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.08 applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

(g) [reserved].

(h) Notes repurchased by the Issuer pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be retired and canceled at the option of the Issuer. Notes purchased by a third party pursuant to clauses (f) and (g) will have the status of Notes issued and outstanding.

(i) At the time the Issuer delivers Notes to the Trustee which are to be accepted for purchase, the Issuer shall also deliver an Officers’ Certificate stating that such Notes are to be accepted by the Issuer pursuant to and in accordance with the terms of this Section 4.08.

91

A 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.

(j) The Issuer 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 Notes pursuant to this Section 4.08. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.08 by virtue thereof.

(k) If holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described above, purchases all of the Notes validly tendered and not withdrawn by such holders, the Issuer or such third party will have the right, upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all Notes that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest to, but excluding, the date of redemption. Any such redemption shall be effected pursuant to Article III.

(l) Prior to any Change of Control Offer, the Issuer shall deliver to the Trustee an Officers’ Certificate stating that all conditions precedent contained herein to the right of the Issuer to make such offer have been complied with.

SECTION 4.09 Compliance Certificate. The Issuer shall deliver to the Trustee within 120 days after the end of each fiscal year of the Issuer, beginning with the fiscal year ending on December 31, 2023, an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Authorized Officers of the Issuer they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period. If they do, the certificate shall describe the Default, its status and what action the Issuer is taking or proposes to take with respect thereto. In addition, the Issuer shall deliver to the Trustee, within five Business Days after any Authorized Officer of the Issuer becomes aware of any Default or Event of Default, written notice of such Default or Event of Default, its status and what action the Issuer is taking or proposes to take in respect thereof. Except with respect to receipt of payments of principal and interest on the Notes and any Event of Default information contained in the Officers’ Certificate delivered to it pursuant to this Section 4.09, the Trustee shall have no duty to review, ascertain or confirm the Issuer’s compliance with or the breach of any representation, warranty or covenant made in this Indenture.

The Issuer shall cause (i) each Wholly Owned Restricted Subsidiary (other than any Excluded Subsidiary), (ii) any Subsidiary that ceases to be an Excluded Subsidiary and is a Wholly Owned Restricted Subsidiary and (iii) any other Subsidiary that guarantees any Indebtedness of the Issuer or any of the Subsidiary Guarantors to execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit B hereto pursuant to which such Subsidiary will guarantee the Issuer’s Obligations under the Notes and this Indenture on the terms and conditions set forth in this

92

Indenture, a joinder to the Collateral Agreement, and, to the extent required pursuant to Section 4.15, a joinder agreement to each applicable Security Document or new Security Documents, if required by the Senior Lien Intercreditor Agreement, a joinder to the Senior Lien Intercreditor Agreement, and if required by any Customary Intercreditor Agreement, a joinder to such Customary Intercreditor Agreement. Each Subsidiary Guarantee shall be released in accordance with Section 12.02.

SECTION 4.11 Liens.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, Incur or suffer to exist any Lien (except Permitted Liens) on any asset or property of the Issuer or such Restricted Subsidiary securing Indebtedness of the Issuer or any of its Restricted Subsidiaries.

(b) [Reserved].

(c) For purposes of determining compliance with this Section 4.11, (i) a Lien securing an item of Indebtedness need not be permitted solely by reference to one category of Permitted Liens described in the definition of “Permitted Liens” or pursuant to Section 4.11(a) but may be permitted in part under any combination thereof and (ii) in the event that a Lien securing an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of one or more of the categories of Permitted Liens described in the definition of “Permitted Liens”, the Issuer shall, in its sole discretion, classify or reclassify, or later divide, classify or reclassify, such Lien securing such item of Indebtedness (or any portion thereof) in any manner that complies with this Section 4.11 and will only be required to include the amount and type of such Lien or such item of Indebtedness secured by such Lien in one of the clauses of the definition of “Permitted Liens” and such Lien securing such item of Indebtedness will be treated as being Incurred or existing pursuant to only one of such clauses.

(d) With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness means any increase in the amount of such Indebtedness in connection with any accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms or in the form of common stock of the Issuer, the payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class, accretion of original issue discount or liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness described in clause (3) of the definition of “Indebtedness.”

SECTION 4.12 [Intentionally Omitted].

93

SECTION 4.13 Maintenance of Office or Agency.

(a) The Issuer shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or Registrar) where Notes may be surrendered for registration of transfer or for exchange. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the Corporate Trust Office of the Trustee as set forth in Section 13.02.

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

(c) The Issuer hereby designates the Corporate Trust Office of the Trustee or its agent as such office or agency of the Issuer in accordance with Section 2.04.

SECTION 4.14 Covenant Suspension Event. If on any date following the Issue Date, (i) the Notes have Investment Grade Ratings from both Rating Agencies, and (ii) no Default has occurred and is continuing, then, beginning on that day (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the following provisions of this Indenture will no longer be applicable (collectively, the “Suspended Covenants”):

(1) Section 4.03 (Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock);

(2) Section 4.04 (Limitation on Restricted Payments);

(3) Section 4.05 (Dividend and Other Payment Restrictions Affecting Subsidiaries);

(4) Section 4.06 (Asset Sales);

(5) Section 4.07 (Transactions with Affiliates);

(6) Section 4.10 (Future Guarantors);

(7) Section 4.15 (After-Acquired Property); and

(8) Section 5.01(a)(iv) (Merger, Amalgamation, Consolidation or Sale of All or Substantially All Assets).

In the event that the Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating, then the Issuer and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. The period of time between the Covenant Suspension Event and the Reversion Date is referred to as the “Suspension Period.”

94

On each Reversion Date, all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be classified as having been Incurred or issued pursuant to Sections 4.03(a) or one of the clauses set forth in Section 4.03(b) (to the extent such Indebtedness or Disqualified Stock or Preferred Stock would be permitted to be Incurred or issued thereunder as of the Reversion Date and after giving effect to Indebtedness Incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness or Disqualified Stock or Preferred Stock would not be so permitted to be Incurred or issued pursuant to Sections 4.03(a) or (b), such Indebtedness or Disqualified Stock or Preferred Stock will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.03(b)(iii). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.04 will be made as though Section 4.04 had been in effect since the Issue Date and prior to, but not during, the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will not reduce the amount available to be made as Restricted Payments under Section 4.04(a). No Default or Event of Default will be deemed to have occurred on the Reversion Date as a result of any actions taken by the Issuer or its Restricted Subsidiaries during the Suspension Period. Within 30 days of such Reversion Date, the Issuer must comply with the terms of Section 4.10.

For purposes of Section 4.06, on the Reversion Date, the unutilized Excess Proceeds amount will be reset to zero.

The Issuer shall provide the Trustee with written notice of each Covenant Suspension Event or Reversion Date within five Business Days of the occurrence thereof. The Trustee shall have no duty to monitor or provide notice to the holders of Notes of any such Covenant Suspension Event or Reversion Date.

SECTION 4.15 After-Acquired Property.

(a) Upon the acquisition by the Issuer or any Subsidiary Guarantor of any First-Priority After-Acquired Property, or upon any additional Restricted Subsidiary becoming a Subsidiary Guarantor that has First-Priority After-Acquired Property, the Issuer or such Subsidiary Guarantor shall execute and deliver such mortgages, deeds of trust, security instruments, financing statements and other Security Documents and, if necessary, terminations of existing mortgages, deeds of trust, security instruments, financing statements or other security documents, as shall be reasonably necessary to vest in the Collateral Agent (or its agent) a perfected second-priority security interest, subject only to Permitted Liens, in such First-Priority After-Acquired Property and to have such First-Priority After-Acquired Property (but subject to the limitations described in the Security Documents, the Senior Lien Intercreditor Agreement and limitations under applicable local law) added to the Collateral, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such First-Priority After-Acquired Property to the same extent and with the same force and effect.

95

(b) Notwithstanding the foregoing, if granting a security interest in any property pursuant to the foregoing clause (a) requires the consent of a third party, the Issuer will use commercially reasonable efforts to obtain such consent with respect to such security interest for the benefit of the Collateral Agent (or its agent) on behalf of the Secured Parties. If such third party does not consent to the granting of such security interest after the use of such commercially reasonable efforts, the applicable entity will not be required to provide such security interest.

(c) The Issuer shall review each Reserve Report prepared as of each June 30th and December 31st (which shall be prepared by no later than September 30th of the same year for Reserve Reports as of June 30th and March 31st of the following year for Reserve Reports as of December 31st) and the list of current Mortgaged Properties, to ascertain whether the PV-10 of the Mortgaged Properties (calculated at the time of redetermination) meets the Collateral Coverage Minimum after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the PV-10 of the Mortgaged Properties (calculated at the time of review) does not meet the Collateral Coverage Minimum, then the Issuer shall use best efforts, and shall cause the Subsidiary Guarantors to use best efforts, to grant, no later than (i) with respect to the Reserve Report prepared as of December 31st, April 30th of the following fiscal year and (ii) with respect to the Reserve Report prepared as of June 30th, October 31st of the same fiscal year, to the Collateral Agent (or its agent) as security for the Notes Obligations a second-priority Lien interest (subject to Permitted Liens and the Senior Lien Intercreditor Agreement and the Second Lien Intercreditor Agreement) on additional Oil and Gas Properties not already subject to a Lien of the Security Documents such that, after giving effect thereto, the PV-10 of the Mortgaged Properties (calculated at the time of review) meets the Collateral Coverage Minimum. All such Liens will be created and perfected by and in accordance with the provisions of the Security Documents, including, if applicable, any additional Mortgages. In order to comply with the foregoing, if any Restricted Subsidiary places a Lien on its property and such Subsidiary is not a Subsidiary Guarantor, then it shall become a Subsidiary Guarantor and comply with the provisions of Section 4.15(a) and (b).

Notwithstanding anything herein to the contrary, (i) if the Issuer or any Subsidiary Guarantor grants a lien on any assets to secure any Secured Bank Indebtedness, the Issuer or the applicable Subsidiary Guarantor shall be required to provide a perfected second-priority security interest in such assets, subject to only Permitted Liens, to secure the Notes Obligations and (ii) if the Issuer or any Subsidiary Guarantor grants a lien on any assets to secure any Other Second-Lien Obligations, the Issuer or the applicable Subsidiary Guarantor shall be required to provide a perfected second-priority security interest in such assets, pari passu with such Other Second-Lien Obligations, subject to only Permitted Liens, to secure the Notes Obligations.

(ii) appoints a Custodian of the Issuer or any Significant Subsidiary or for any substantial part of its property; or

(iii) orders the winding up or liquidation of the Issuer or any Significant Subsidiary or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days;

(h) there is a failure by the Issuer or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $35.0 million or its foreign currency equivalent (net of any amounts which are covered by enforceable insurance policies issued by solvent carriers), which judgments are not discharged, waived or stayed for a period of 60 days;

(i) the Subsidiary Guarantee of a Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) with respect to the Notes ceases to be in full force and effect (except as contemplated by the terms thereof) or the Issuer or any Subsidiary Guarantor that qualifies as a Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) denies or disaffirms its obligations under this Indenture or any Subsidiary Guarantee with respect to the Notes and such Default continues for 10 days;

(j) unless such Liens have been released in accordance with the provisions of this Indenture, the Security Documents, the Senior Lien Intercreditor Agreement or any Customary Intercreditor Agreement, Liens in favor of the holders of the Notes with respect to Collateral with a Fair Market Value in excess of $100.0 million cease to be valid or enforceable and such Default continues for 30 days, or the Issuer shall assert or any Subsidiary Guarantor shall assert, in any pleading in any court of competent jurisdiction, that any such security interest is invalid or unenforceable and, in the case of any Subsidiary Guarantor, the Issuer fails to cause such Subsidiary Guarantor to rescind such assertions within 30 days after the Issuer has actual knowledge of such assertions;

100

(k) the failure to consummate the Special Mandatory Redemption, to the extent required, as described in Article III; or

(l) there is a failure by the Issuer to comply for 15 days after receipt of written notice given by the Trustee or the holders of not less than 30% in aggregate principal amount of the Notes then outstanding (with a copy to the Trustee) with any of its obligations, covenants or agreements under Section 5.01(a).

The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

However, a default under clause (c), (d), (h) or (l) above shall not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of outstanding Notes (with a copy to the Trustee) notify the Issuer of the Default and the Issuer does not cure such Default within the time specified in clause (c), (d), (h) or (l) as applicable, after receipt of such notice; provided that a notice of Default may not be given with respect to any action taken, and reported publicly or to holders, more than two years prior to such notice of Default. Any notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more holders of the Notes (each a “Directing Holder”) must be accompanied by a written representation from each such holder delivered to the Issuer and the Trustee that such holder is not (or, in the case such holder is the Depository or its nominee, that such holder is being instructed solely by beneficial owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Issuer with such other information as the Issuer may reasonably request from time to time in order to verify the accuracy of such Noteholder’s Position Representation within five Business Days of request therefor (a “Verification Covenant”). In any case in which the holder is the Depository or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Notes in lieu of the Depository or its nominee and the Depository shall be entitled to conclusively rely on such Position Representation and Verification Covenant in delivering its direction to the Trustee.

If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Issuer determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officers’ Certificate stating that the Issuer has initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Default, Event of Default or acceleration (or notice thereof) that resulted from the applicable Noteholder Direction, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to such Default or Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such

101

matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Issuer provides to the Trustee an Officers’ Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Default or Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such holder, the percentage of the Notes held by the remaining holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Default or Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default.

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default as the result of a bankruptcy or similar proceeding shall not require compliance with the foregoing paragraphs.

For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this Indenture, shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any Officers’ Certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The Trustee shall have no liability to the Issuer, any holder or any other Person in acting in good faith on a Noteholder Direction.

The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

SECTION 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(f) or (g) with respect to the Issuer) occurs and is continuing, the Trustee or the holders of at least 30% in principal amount of outstanding Notes (with a copy to the Trustee) by notice to the Issuer may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. Upon the Trustee’s or the holders’ of at least 30% in principal amount of outstanding Notes notification to the Issuer of such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(f) or (g) with respect to the Issuer occurs, the principal of, premium, if any, and interest on all the Notes shall ipso facto 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 outstanding Notes by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

102

In the event of any Event of Default specified in Section 6.01(e), such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the holders of the Notes, if within 20 days after such Event of Default arose the Issuer delivers an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the Notes as described above be annulled, waived or rescinded upon the happening of any such events.

If the Notes are accelerated or otherwise become due prior to their maturity date as a result of an Event of Default or by operation of law or a Premium Event occurs, the principal of, accrued and unpaid interest and premium on the Notes subject to such Premium Event shall be due and payable. If the Notes are accelerated or otherwise become due prior to their maturity date, in each case, as a result of an Event of Default or by operation of law or any Premium Event occurs prior to the First Call Date, the amount of principal of, accrued and unpaid interest and premium on the Notes that becomes due and payable shall equal the redemption price applicable with respect to an optional redemption of such Notes, in effect on the date of such acceleration, Premium Event or the date on which such Notes otherwise become due as if such acceleration or other circumstance causing such Notes to become due were an optional redemption of the Notes accelerated or becoming due (the “Redemption Premium”). In any such case, the Redemption Premium shall constitute part of the Notes Obligations, and constitutes liquidated damages, not unmatured interest or a penalty, as the actual amount of damages to the holders as a result of the relevant Premium Event would be impracticable and extremely difficult to ascertain. Accordingly, the Redemption Premium is provided by mutual agreement of the Issuer and the Guarantors and the holders of the Notes as a reasonable estimation and calculation of such actual lost profits and other actual damages of such holders. Without limiting the generality of the foregoing, it is understood and agreed that upon the occurrence of any Premium Event, the Redemption Premium shall be automatically and immediately due and payable with respect to any Notes subject to the Premium Event as though any Notes subject to such Premium Event were voluntarily prepaid as of such date and shall constitute part of the Notes Obligations secured by the Collateral. The Redemption Premium shall also be automatically and immediately due and payable if the Notes are satisfied or released by foreclosure (whether by power of judicial proceeding or otherwise), deed in lieu of foreclosure or by any other means. THE ISSUER AND THE GUARANTORS HEREBY EXPRESSLY WAIVE (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR OTHER LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING REDEMPTION PREMIUM IN CONNECTION WITH ANY SUCH EVENTS OR THE COMMENCEMENT OF ANY BANKRUPTCY OR INSOLVENCY EVENT. The Issuer and the Guarantors expressly agree (to the fullest extent it and they may lawfully do so) that with respect to the Redemption Premium payable under the terms of this Indenture: (i) the Redemption Premium is reasonable and is the product of an arm’s length transaction between sophisticated business parties, ably represented by counsel; (ii) the Redemption Premium shall be payable notwithstanding the then-prevailing market rates at the time payment is made; (iii) there has been a course of conduct between the holders of the Notes and the Issuer and the Guarantors giving specific consideration in this transaction for such

103

agreement to pay the Redemption Premium; and (iv) the Issuer and the Guarantors shall be estopped hereafter from claiming differently than as agreed to in this paragraph. The Issuer and the Guarantors expressly acknowledge that their agreement to pay the Redemption Premium as herein described is a material inducement to the holders of the Notes to purchase the Notes.

SECTION 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes, this Indenture or the Security Documents.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. To the extent required by law, all available remedies are cumulative.

SECTION 6.04 Waiver of Past Defaults. Provided the Notes are not then due and payable by reason of a declaration of acceleration, the holders of a majority in principal amount of the Notes then outstanding by written notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the principal of or interest on a Note, (b) a Default arising from the failure to redeem or purchase any Note when required pursuant to the terms of this Indenture or (c) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each holder affected. When a Default is waived, it is deemed cured and the Issuer, the Trustee and the holders will be restored to their former positions and rights under this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05 Control by Majority. The holders of a majority in principal amount of then 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. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Article VII, that the Trustee determines is unduly prejudicial to the rights of any other holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such holders) or that would involve the Trustee in personal liability or expenses for which it is not adequately indemnified; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

SECTION 6.06 Limitation on Suits.

(a) Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder may pursue any remedy with respect to this Indenture, the Notes or the Security Documents unless:

(i) such holder has previously given the Trustee written notice that an Event of Default is continuing,

104

(ii) holders of at least 30% in principal amount of the outstanding Notes have requested the Trustee in writing to pursue the remedy,

(iii) such holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense,

(iv) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity, and

(v) the holders of a majority in principal amount of the outstanding Notes have not given the Trustee a written direction inconsistent with such request within such 60-day period.

(b) A holder may not use this Indenture to prejudice the rights of another holder or to obtain a preference or priority over another holder.

SECTION 6.07 Contractual Rights of the Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the contractual right of any holder to receive payment of principal of and interest on the Note held by such holder, on or after the respective due dates thereof, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such holder.

SECTION 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes for the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Notes) and any amount due hereunder.

SECTION 6.09 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim, statements of interest and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements and advances of the Trustee (including counsel, accountants, experts or such other professionals as the Trustee deems necessary, advisable or appropriate)) and the holders allowed in any judicial proceedings relative to the Issuer, the Guarantors, their creditors or their property, shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee hereunder. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any holder, or to authorize the Trustee to vote in respect of the claim of any holder in any such proceeding.

105

SECTION 6.10 Application of Funds. After the exercise of remedies (or after all Notes have automatically become immediately due and payable), any amounts received by the Trustee on account of the Obligations shall, subject to the Senior Lien Intercreditor Agreement and the Second Lien Intercreditor Agreement, be applied by the Trustee in accordance with Section 4.02 of the Collateral Agreement.

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

SECTION 6.12 Waiver of Stay or Extension Laws. Neither the Issuer nor any Guarantor (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer and the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VII

The Trustee shall be under no duty to make any investigation as to any statement contained in any such instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. However, in the case of certificates or opinions required by any provision hereof to be provided to it, the Trustee shall examine the form of certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

SECTION 7.02 Rights of Trustee.

(a) The Trustee may conclusively rely upon and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, judgment, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper person or persons, not only as to due execution, validity and effectiveness, but also as to the truth and accuracy of any information contained therein. The Trustee need not investigate any fact or matter stated in the document.

107

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

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

(d) The Trustee shall not be responsible or liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence as determined by a court of competent jurisdiction in a final non-appealable order.

(e) The Trustee may consult with counsel of its own selection and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Notes shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, judgment, approval, bond, debenture, note or other paper or document unless requested in writing to do so by the holders of not less than a majority in principal amount of the Notes at the time outstanding, and indemnified in accordance with Section 6.05, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney, at the expense of the Issuer and shall Incur no liability of any kind by reason of such inquiry or investigation.

(g) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture or the Security Documents at the written request or direction of any of the holders pursuant to this Indenture, unless, subject to the terms hereof, such holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be Incurred by it in compliance with such request or direction.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder, including the Collateral Agent.

(i) The Trustee shall not be responsible or liable for any action taken or omitted by it in good faith at the direction of the holders of not less than a majority in principal amount of the Notes as to the time, method and place of conducting any proceedings for any remedy available to the Trustee or the exercising of any power conferred by this Indenture.

108

(j) Any action taken, or omitted to be taken, by the Trustee in good faith pursuant to this Indenture upon the request or authority or consent of any person who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and binding upon future holders of Notes and upon Notes executed and delivered in exchange therefor or in place thereof.

(k) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office from the Issuer, any Guarantor or any holder, and such notice references the Notes and this Indenture.

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

(m) The Trustee shall not be responsible or liable for punitive, special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of actions.

SECTION 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Guarantees or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuer or any Guarantor in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication. The Trustee shall not be charged with knowledge of any Default or Event of Default under Sections 6.01(c), (d), (e), (f), (g), (h), (i), (j), (k) or (l), or of the identity of any Significant Subsidiary unless either (a) a Trust Officer shall have actual

109

knowledge thereof or (b) the Trustee shall have received written notice thereof in accordance with Section 13.02 hereof from the Issuer, any Guarantor or any holder. In accepting the trust hereby created, the Trustee acts solely as Trustee under this Indenture and not in its individual capacity and all persons, including without limitation the holders of Notes and the Issuer having any claim against the Trustee arising from this Indenture shall look only to the funds and accounts held by the Trustee hereunder for payment except as otherwise provided herein.

SECTION 7.05 Notice of Defaults. If a Default occurs and is continuing and is actually known to a Trust Officer, the Trustee shall mail, or deliver electronically if held by the Depository, to each holder of the Notes notice of the Default within the later of 90 days after it occurs or 30 days after it is actually known to a Trust Officer or written notice of it is received by the Trustee at the Corporate Trust Office. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Note, the Trustee may withhold notice if and so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interests of the noteholders. The Issuer is required to deliver to the Trustee, annually, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year and whether such Default is continuing and, if so, proposed steps to cure such Default. The Issuer also is required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action the Issuer is taking or proposes to take in respect thereof.

SECTION 7.06 [Reserved].

SECTION 7.07 Compensation and Indemnity. The Issuer shall pay to the Trustee (acting in any capacity hereunder) and the Collateral Agent from time to time compensation for their acceptance of this Indenture and their services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee and the Collateral Agent upon request for all reasonable out-of-pocket expenses Incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s and the Collateral Agent’s agents, counsel, accountants and experts. The Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee (acting in any capacity hereunder) and the Collateral Agent or any predecessor Trustee or Collateral Agent and their directors, officers, employees and agents against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses and including taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) Incurred by or in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture or any Guarantee against the Issuer or any Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by the Issuer, any Guarantor, any holder or any other Person). The obligation to pay such amounts shall survive the payment in full or defeasance of the Notes or the removal or resignation of the Trustee and/or the Collateral Agent. The Trustee shall notify the Issuer of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Issuer shall not relieve the Issuer or any Guarantor of its indemnity obligations hereunder. The Issuer shall defend the claim and the indemnified party shall provide reasonable cooperation at the Issuer’s expense in the defense. Such indemnified parties may have

110

separate counsel and the Issuer and such Guarantors, as applicable, shall pay the fees and expenses of such counsel; provided, however, that the Issuer shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no actual or potential conflict of interest between the Issuer and the Guarantor, as applicable, and such parties in connection with such defense. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense Incurred by an indemnified party through such party’s own willful misconduct or negligence (as determined by a court of competent jurisdiction in a final non-appealable order).

To secure the Issuer’s and the Guarantors’ payment obligations hereunder, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes.

(iii) no Default specified in Section 6.01(f) or (g) with respect to the Issuer shall have occurred or is continuing on the date of such deposit;

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Issuer upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, holders entitled to the money must look to the Issuer for payment as general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

(b) Notwithstanding anything herein to the contrary, in connection with (x) any release of Collateral pursuant to Section 11.04(a)(2) or (3), such Collateral may not be released from the Lien and security interest created by the Security Documents and (y) any release of Collateral pursuant to Section 11.04(a)(1) and (7), the Collateral Agent shall not be required to execute, deliver or acknowledge any instruments of termination, satisfaction or release unless, in each case, an Officers’ Certificate and Opinion of Counsel certifying that all conditions precedent, including, without limitation, this Section 11.04, have been met and stating under which of the circumstances set forth in Section 11.04(a) above the Collateral is being released have been delivered to the Collateral Agent on or prior to the date of such release or, in the case of clause (y) above, the date on which the Collateral Agent executes any such instrument.

SECTION 11.05 Powers Exercisable by Receiver or Trustee.

For all purposes hereof and the Senior Lien Intercreditor Agreement, the Issuer hereby designates the Obligations pursuant to the Credit Agreement as in effect on the Issue Date as “First-Priority Lien Obligations.”

ARTICLE XII

GUARANTEE

SECTION 12.01 Guarantee.

(a) Each Guarantor hereby jointly and severally, irrevocably and unconditionally guarantees, on a senior basis, as a primary obligor and not merely as a surety, to each holder, to the Trustee and to the Collateral Agent and its successors and assigns (i) the performance and punctual payment when due, whether at Stated Maturity, by acceleration or otherwise, of all obligations of the Issuer under this Indenture and the Notes, whether for payment of principal of, premium, if any, or interest on the Notes and all other monetary obligations of the Issuer under this Indenture and the Notes and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuer whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). The Guaranteed Obligations of all Guarantors shall be secured by security interests (subject to Permitted Liens and Liens permitted by Section 4.11) in the Collateral owned by such Guarantor pursuant to the terms of the Security Documents (but subject to the terms and conditions of the Security Documents, the Senior Lien Intercreditor Agreement and the Second Lien Intercreditor Agreement). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from any Guarantor, and that each Guarantor shall remain bound under this Article XII notwithstanding any extension or renewal of any Guaranteed Obligation.

(b) Each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Notes or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the failure

128

of any holder, the Collateral Agent or the Trustee to assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Notes or any other agreement or otherwise; (ii) any extension or renewal of this Indenture, the Notes or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (iv) the release of any security held by any holder, the Collateral Agent or the Trustee for the Guaranteed Obligations or each Guarantor; (v) the failure of any holder, the Collateral Agent or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of each Guarantor, except as provided in Section 12.02(b). Each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed.

(c) Each Guarantor hereby waives any right to which it may be entitled to have the assets of the Issuer first be used and depleted as payment of the Issuer’s or such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to which it may be entitled to require that the Issuer be sued prior to an action being initiated against such Guarantor.

(d) Each Guarantor further agrees that its Guarantee 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 Guaranteed Obligations.

(e) The Guarantee of each Guarantor is, to the extent and in the manner set forth in Article XII, equal in right of payment to all existing and future Pari Passu Indebtedness (but subject to the terms and conditions of the Security Documents, the Senior Lien Intercreditor Agreement and the Second Lien Intercreditor Agreement), senior in right of payment to all existing and future Subordinated Indebtedness of such Guarantor.

(f) Except as expressly set forth in Sections 8.01(b), 12.02 and 12.06, the obligations of each 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 Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any holder, the Collateral Agent or the Trustee to assert any claim or demand or to enforce any remedy under this 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 Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

129

(g) Each Guarantor agrees that its Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Each Guarantor further agrees that its 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 Guaranteed Obligation is rescinded or must otherwise be restored by any holder or the Trustee upon the bankruptcy or reorganization of the Issuer or otherwise.

(h) In furtherance of the foregoing and not in limitation of any other right which any holder, the Collateral Agent or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee or Collateral Agent, forthwith pay, or cause to be paid, in cash, to the holders or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the Issuer to the holders, the Collateral Agent and the Trustee.

(i) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the holders, the Collateral Agent and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article VI, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purposes of this Section 12.01.

(j) Each Guarantor also agrees to pay any and all costs and expenses (including reasonable out-of-pocket attorneys’ fees and expenses) Incurred by the Trustee, the Collateral Agent or any holder in enforcing any rights under this Section 12.01.

(k) Upon request of the Trustee, each Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 12.02 Limitation on Liability.

(a) Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by each Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed by the applicable Subsidiary Guarantor without rendering the Subsidiary Guarantee or 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 or capital maintenance or corporate benefit rules applicable to guarantees for obligations of affiliates.

130

(b) A Subsidiary Guarantee as to any Restricted Subsidiary that is (or becomes) a party hereto on the date hereof or that executes a supplemental indenture in accordance with Section 4.10 hereof and provides a guarantee shall terminate and be of no further force or effect and such Subsidiary Guarantee shall be deemed to be automatically released from all obligations under this Article XII upon any of the following:

(i) the sale, disposition, exchange or other transfer (including through merger, consolidation, amalgamation or otherwise) of the Capital Stock (including any sale, disposition or other transfer following which the applicable Subsidiary Guarantor is no longer a Restricted Subsidiary), of the applicable Subsidiary Guarantor if such sale, disposition, exchange or other transfer is made to a person that is not the Issuer or a Restricted Subsidiary of the Issuer in a transaction that is permitted by this Indenture;

(ii) the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the provisions of Section 4.04 and the definition of “Unrestricted Subsidiary”;

(iii) [reserved];

(iv) the Issuer’s exercise of its legal defeasance option or covenant defeasance option under Article VIII or if the Issuer’s obligations under this Indenture are discharged in accordance with the terms of this Indenture;

(v) such Subsidiary ceasing to be a Subsidiary as a result of any foreclosure of any pledge or security interest in favor of First-Priority Lien Obligations or other exercise of remedies in respect thereof, subject to, in each case, the application of the proceeds of such foreclosure or exercise of remedies in the manner described in the Senior Lien Intercreditor Agreement; and

(vi) as provided in Article IX.

SECTION 12.03 [Reserved].

SECTION 12.04 Successors and Assigns. This Article XII shall be binding upon each Guarantor and its successors and assigns and shall inure 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 Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 12.05 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 XII 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 XII at law, in equity, by statute or otherwise.

131

SECTION 12.06 Modification. No modification, amendment or waiver of any provision of this Article XII, nor the consent to any departure by any 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 Guarantor in any case shall entitle any Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 12.07 Execution of Supplemental Indenture for Future Subsidiary Guarantors. Each Subsidiary which is required to become a Subsidiary Guarantor of the Notes pursuant to Section 4.10 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit B hereto pursuant to which such Subsidiary shall become a Subsidiary Guarantor under this Article XII and shall guarantee the Notes. Concurrently with the execution and delivery of such supplemental indenture, the Issuer shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate certifying that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Subsidiary Guarantee of such Subsidiary Guarantor is a valid and binding obligation of such Subsidiary Guarantor, enforceable against such Subsidiary Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request.

SECTION 12.08 Non-Impairment. The failure to endorse a Guarantee on any Note shall not affect or impair the validity thereof.

The Notes are subject to all terms and provisions of the Indenture, and the holders (as defined in the Indenture) are referred to the Indenture for a statement of such terms and provisions. If and to the extent that any provision of the Notes limits, qualifies or conflicts with a provision of the Indenture, such provision of the Indenture shall control.

The Indenture also imposes limitations on the ability of the Issuer and each Subsidiary Guarantor to consolidate or merge with or into any other Person or convey, transfer or lease all or substantially all of its property.

To guarantee the due and punctual payment of the principal and interest on the Notes and all other amounts payable by the Issuer under the Indenture and the Notes when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Notes and the Indenture, the Guarantors have unconditionally guaranteed the Guaranteed Obligations pursuant to the terms of the Indenture and any Subsidiary Guarantor that executes a Subsidiary Guarantee will unconditionally guarantee the Guaranteed Obligations on a senior secured basis pursuant to the terms of the Indenture.

If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under the Indenture or the Security Documents at the written request or direction of any of the holders unless such holders have offered to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense and certain other conditions are complied with. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder may pursue any remedy with respect to the Indenture, the Notes or the Security Documents unless (i) such holder has previously given the Trustee written notice that an Event of Default is continuing, (ii) holders of at least 30% in principal amount of the outstanding Notes have requested in writing that the Trustee pursue the remedy, (iii) such holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense, (iv) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity, and (v) the holders of a majority in principal amount of the outstanding Notes have not given the Trustee a written direction inconsistent with such request within such 60-day period. Subject to certain restrictions, the holders of a majority in principal amount of outstanding Notes are given the right to 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. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such holders) or that would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification reasonably satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

17. Trustee Dealings with the Issuer

Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Issuer or its Affiliates and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee.

18. No Recourse Against Others

No director, officer, employee, manager, incorporator or holder of any Equity Interests in the Issuer or any Guarantor or any direct or indirect parent companies, as such, will have any liability for any obligations of the Issuer or any Guarantor under the Notes, the Indenture or the Guarantees, as applicable, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of Notes by accepting a Note waives and releases all such liability.

19. Authentication
