Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the holders of (i) $500,000,000 aggregate principal amount of the Issuers’ 73/8% Senior Notes due 2021 issued on the date hereof (the “Initial Notes”), (ii) Exchange Notes (as defined below) issued in exchange for the Initial Notes and (iii) Additional Notes issued from time to time (together with the Initial Notes and the Exchange Notes, the “Notes”):

ARTICLE I

DEFINITIONS AND INCORPORATION BY REFERENCE

SECTION 1.01 Definitions.

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

(1) Indebtedness of any other Person existing at the time such other Person is merged, consolidated or amalgamated with or into or became a Restricted Subsidiary of such specified Person, and

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

Acquired Indebtedness will be deemed to have been Incurred, with respect to clause (1) of the preceding sentence, on the date such Person becomes a Restricted Subsidiary and, with respect to clause (2) of the preceding sentence, on the date of consummation of such acquisition of such assets.

“Additional Assets” means:

(1) any properties or assets used or useful in the Oil and Gas Business;

(2) capital expenditures by Holdings or a Restricted Subsidiary in the Oil and Gas Business;

(3) the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by Holdings or another Restricted Subsidiary; or

(4) Capital Stock constituting a minority interest in any Person that at such time is a Restricted Subsidiary;

provided, however, that, in the case of clauses (3) and (4), such Restricted Subsidiary is primarily engaged in the Oil and Gas Business.

“Additional Notes” means the Notes issued under the terms of this Indenture subsequent to the Issue Date.

“Additional Refinancing Amount” means, in connection with the Incurrence of any Refinancing Indebtedness, the aggregate principal amount of additional Indebtedness, Disqualified Stock or Preferred Stock Incurred to pay premiums (including tender premiums), expenses, defeasance costs and fees in respect thereof.

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

(a) the sum of:

(i) estimated discounted future net revenues from proved oil and natural gas reserves of Holdings and its Restricted Subsidiaries calculated in accordance with SEC guidelines before any provincial, territorial, state, federal or foreign income taxes, as estimated by Holdings in a reserve report prepared as of the end of Holdings’ most recently completed fiscal year for which audited financial statements are available, as increased by, as of the date of determination, the estimated discounted future net revenues from (A) estimated proved oil and natural gas reserves acquired since such year end, which reserves were not reflected in such year end reserve report, and (B) estimated oil and natural gas reserves attributable to upward revisions of estimates of proved oil and natural gas reserves (including the impact to discounted future net revenues related to development costs previously estimated in the last year end reserve report, but only to the extent such costs were actually incurred since the date of the last year end reserve report) since such year end due to exploration, development, exploitation or other activities, increased by the accretion of discount from the date of the last year end reserve report to the date of determination and decreased by, as of the date of determination, the estimated discounted future net revenues from (C) estimated proved oil and natural gas reserves included in the last year end reserve report that shall have been produced or disposed of since such year end, and (D) estimated oil and natural gas reserves included therein that are subsequently removed from the proved oil and natural gas reserves of Holdings and its Restricted Subsidiaries as so calculated due to downward revisions of estimates of proved oil and natural 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 natural gas reserves shall be determined in their entirety using oil, natural 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 Holdings were year end or (2) if Holdings 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 natural 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 natural 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 as provided in the definition of “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 case as estimated by Holdings’ petroleum engineers or any independent petroleum engineers engaged by Holdings for that purpose;

(ii) the capitalized costs that are attributable to Oil and Gas Properties of Holdings and its Restricted Subsidiaries to which no proved oil and natural gas reserves are attributable, based on Holdings’ books and records as of a date no earlier than the date of Holdings’ latest annual or quarterly consolidated financial statements;

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

(iv) assets related to commodity risk management activities less liabilities related to commodity risk management activities, in each case to the extent that such assets and liabilities arise in the ordinary course of the Oil and Gas Business, provided that such net value shall not be less than zero; and

(v) the greater of (A) the net book value of other tangible assets (including, without limitation, investments in unconsolidated Restricted Subsidiaries and mineral rights held under lease or other contractual arrangement) of Holdings and its Restricted Subsidiaries, as of a date no earlier than the date of Holdings’ latest annual or quarterly consolidated financial statements, and (B) the Fair Market Value, as estimated by Holdings, of other tangible assets (including, without limitation, investments in unconsolidated Restricted Subsidiaries and mineral rights held under lease or other contractual arrangement) of Holdings and its Restricted Subsidiaries, as of a date no earlier than the date of Holdings’ latest audited consolidated financial statements (it being understood that Holdings shall not be required to obtain any appraisal of any assets); minus

(b) the sum of:

(i) any amount included in clauses (a)(i) through (a)(v) above that is attributable to minority interests;

(ii) any net natural gas balancing liabilities of Holdings and its Restricted Subsidiaries reflected in Holdings’ latest audited consolidated financial statements;

(iii) to the extent included in clause (a)(i) above, the estimated discounted future net revenues, calculated in accordance with SEC guidelines (utilizing the prices and costs as provided in clause (a)(i)), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of Holdings and its Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and

(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 Holdings and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with respect thereto).

If Holdings changes its method of accounting from the full cost method of accounting to the successful efforts or a similar method, “Adjusted Consolidated Net Tangible Assets” will continue to be calculated as if Holdings were still using the full cost method of accounting.

“Affiliate” of any specified Person means any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For purposes of this definition, “control” (including, with correlative meanings, the terms “controlling,” “controlled by” and “under common control with”), as used with respect to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise.

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).

The Trustee may appoint one or more authenticating agents reasonably acceptable to Holdings 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 Holdings. 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 Issuers 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 Issuers 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 Issuers initially appoint the Trustee as Registrar, Paying Agent and the Notes Custodian with respect to the Global Notes.

(b) The Issuers may enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. Holdings shall notify the Trustee in writing of the name and address of any such agent. If the Issuers fail 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. Holdings or any of its domestically organized Wholly Owned Subsidiaries may act as Paying Agent or Registrar.

(c) The Issuers may remove any Registrar or Paying Agent upon 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 as evidenced by an appropriate agreement entered into by the Issuers 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 Issuers 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 each due date of the principal of and interest on any Note, the Issuers shall deposit with each Paying Agent (or if Holdings or a Wholly Owned 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 Issuers 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 of any default by the Issuers in making any such payment. If Holdings or a Wholly Owned Subsidiary of Holdings 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 Issuers 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, a Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.06 Holder Lists. The Trustee 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, Holdings 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 Issuers shall execute and the Trustee shall authenticate Notes at the Registrar’s request. The Issuers 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. The Issuers 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.

Prior to the due presentation for registration of transfer of any Note, the Issuers, 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 Issuers, 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 Depositary 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 Depositary.

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 Issuers 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 the Issuers 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 Issuers 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 Issuers and the Trustee. If required by the Trustee or the Issuers, such holder shall furnish an indemnity bond sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, the Paying Agent and the Registrar from any loss or liability that any of them may suffer if a Note is replaced and subsequently presented or claimed for payment. The Issuers 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 Issuers in their discretion may pay such Note instead of issuing a new Note in replacement thereof.

Every replacement Note is an additional obligation of the Issuers.

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 as not outstanding. Subject to Section 14.06, a Note does not cease to be outstanding because one of the Issuers or an Affiliate of one of the Issuers 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 Issuers 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 Issuers 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 Issuers 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 Issuers default in a payment of interest on the Notes, the Issuers 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 Issuers may pay the defaulted interest to the Persons who are holders on a subsequent special record date. The Issuers 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 mail or cause to be mailed to each affected holder 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 Issuers 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 state that no representation is made as to the correctness of such numbers, either as printed on the Notes or as contained in any notice of a redemption 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 Issuers shall advise the Trustee 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 14.06 of this Indenture. Any calculation of the Applicable Premium or made pursuant to this Section 2.13 shall be made by Holdings and delivered to the Trustee pursuant to an Officers’ Certificate.

(viii) shares of Preferred Stock of a Restricted Subsidiary issued to Holdings or another Restricted Subsidiary; provided that any subsequent issuance or transfer of any Capital Stock or any other event which results in any Restricted Subsidiary that holds such shares of Preferred Stock of another Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except to Holdings or another Restricted Subsidiary) shall be deemed, in each case, to be an issuance of shares of Preferred Stock not permitted by this clause (viii);

(ix) Indebtedness of a Restricted Subsidiary to Holdings or another Restricted Subsidiary; provided that if a Subsidiary Guarantor incurs such Indebtedness to a Restricted Subsidiary that is not an Issuer or a Subsidiary Guarantor (except in respect of intercompany current liabilities Incurred in the ordinary course of business in connection with the cash management, tax and accounting operations of Holdings and its Subsidiaries), such Indebtedness is subordinated in right of payment to the Subsidiary Guarantee of such Subsidiary Guarantor; provided, further, that any subsequent issuance or transfer of any Capital Stock or any other event which results in any Restricted Subsidiary holding such Indebtedness ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to Holdings or another Restricted Subsidiary or any pledge of such Indebtedness constituting a Permitted Lien but not the transfer thereof upon foreclosure) shall be deemed, in each case, to be an Incurrence of such Indebtedness not permitted by this clause (ix);

For purposes of determining compliance with this Section 4.03:

(1) in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of more than one of the categories of permitted Indebtedness described in clauses (i) through (xxii) of Section 4.03(b) above or is entitled to be Incurred pursuant to Section 4.03(a), then Holdings shall, in its sole discretion, classify or reclassify, or later divide, classify or reclassify, such item of

Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) in any manner that complies with this Section 4.03;

(2) at the time of Incurrence, Holdings will be entitled to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in Section 4.03(a) and (b) without giving pro forma effect to the Indebtedness Incurred pursuant to Section 4.03(b) when calculating the amount of Indebtedness that may be Incurred pursuant to Section 4.03(a);

(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

(4) if any Indebtedness denominated in a foreign currency is exchanged, converted or refinanced into Indebtedness denominated in U.S. dollars, 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) with respect to such exchange, conversion or refinancing shall be deemed to be the amount of U.S. dollars into which such Indebtedness has been exchanged, converted or refinanced at the time of such exchange, conversion or refinancing.

Accrual of interest, the accretion of accreted value, the payment of interest or dividends in the form of additional Indebtedness, Disqualified Stock or Preferred Stock, as applicable, amortization of original issue discount, the accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies will not be deemed to be an Incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this Section 4.03. 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 Holdings 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.

(A) the principal amount (or accreted value, if applicable) of such new Indebtedness does not exceed the principal amount (or accreted value, if applicable), plus any accrued and unpaid interest, of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired for value (plus the amount of any premium required to be paid under the terms of the instrument governing the Subordinated Indebtedness being so redeemed, repurchased, acquired or retired, any tender premiums, plus any defeasance costs, fees and expenses Incurred in connection therewith),

(c) For purposes of determining compliance with this “Restricted Payments” covenant, if a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in clauses (i) — (xix) of Section 4.04, the Issuers will be permitted to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this covenant.

(d) As of the Issue Date, all of the Subsidiaries of Holdings will be Restricted Subsidiaries. Holdings will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the definition of “Unrestricted Subsidiary.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by Holdings and the Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such designation will only be permitted if a Restricted Payment or Permitted Investment in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

SECTION 4.05 Dividend and Other Payment Restrictions Affecting Subsidiaries. Holdings shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of Holdings or such Restricted Subsidiary to:

SECTION 4.06 Asset Sales.

(a) Holdings shall not, and shall not permit any of the Restricted Subsidiaries to, cause or make an Asset Sale, unless (x) Holdings or any Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value (as determined in good faith by Holdings) of the assets sold or otherwise disposed of, and (y) at least 75% of the consideration therefor received by Holdings or such Restricted Subsidiary,

as the case may be, is in the form of Cash Equivalents or Additional Assets; provided that the amount of:

(i) any liabilities (as shown on Holdings’ or a Restricted Subsidiary’s most recent balance sheet or in the notes thereto) of Holdings or a 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,

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

(iii) with respect to any Asset Sale of Oil and Gas Properties by Holdings or any Restricted Subsidiary, the costs and expenses related to the exploration, development, completion or production of such Oil and Gas Properties and activities related thereto agreed to be assumed by the transferee (or an Affiliate thereof),

(iv) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to the extent that Holdings and each other Restricted Subsidiary are released from any guarantee of payment of such Indebtedness in connection with the Asset Sale,

(v) consideration consisting of Indebtedness of Holdings (other than Subordinated Indebtedness) received after the Issue Date from Persons who are not Holdings or any Restricted Subsidiary in connection with the Asset Sale and that is cancelled, and

(vi) any Designated Non-cash Consideration received by Holdings or any Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value (as determined in good faith by Holdings), taken together with all other Designated Non-cash Consideration received pursuant to this Section 4.06(a)(vi) that is at that time outstanding, not to exceed the greater of 10.0% of Adjusted Consolidated Net Tangible Assets and $100.0 million 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(a).

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

(i) to repay (A) Indebtedness constituting Bank Indebtedness and other Pari Passu Indebtedness that is secured by a Lien permitted under this Indenture, (B) Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor,

(C) Obligations under the Notes or (D) other Pari Passu Indebtedness (provided that if an Issuer or any Subsidiary Guarantor shall so reduce Obligations under unsecured Pari Passu Indebtedness, the Issuers 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 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 and Additional Interest, if any, the pro rata principal amount of Notes, in each case other than Indebtedness owed to Holdings or an Affiliate of Holdings;

(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), assets, or property or capital expenditures, in each case (A) used or useful in a Similar Business or (B) that replace the properties and assets that are the subject of such Asset Sale; or

(iii) to invest in Additional Assets.

In the case of Section 4.06(b)(ii), a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment until the 18-month anniversary of the date of the receipt of such Net Proceeds; provided that in the event such binding commitment is later canceled or terminated for any reason before such Net Proceeds are so applied, then such Net Proceeds shall constitute Excess Proceeds unless Holdings or such Restricted Subsidiary enters into another binding commitment (a “Second Commitment”) within six months of such cancellation or termination of the prior binding commitment; provided, further, that Holdings or such Restricted Subsidiary may only enter into a Second Commitment under the foregoing provision one time with respect to each Asset Sale and to the extent such Second Commitment is later cancelled or terminated for any reason before such Net Proceeds are applied or are not applied within 180 days of such Second Commitment, then such Net Proceeds shall constitute Excess Proceeds.

Pending the final application of any such Net Proceeds, Holdings or such Restricted Subsidiary may invest such Net Proceeds in any manner not prohibited by this Indenture. Any Net Proceeds from any Asset Sale that are not applied as provided and within the time period set forth in the first sentence of this 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 clause (i) of this Section 4.06(b), 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 $25.0 million, the Issuers shall make an offer to all holders of Notes (and, at the option of the Issuers, to holders of any Pari Passu Indebtedness) (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes (and such Pari Passu Indebtedness), 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 Pari Passu Indebtedness was issued with

significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest and Additional Interest, if any (or, in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness), to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Section 4.06. The Issuers will commence an Asset Sale Offer with respect to Excess Proceeds within ten (10) Business Days after the date that Excess Proceeds exceeds $25.0 million by mailing 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 Pari Passu Indebtedness) tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, Holdings 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 Pari Passu Indebtedness) surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased in the manner described in Section 4.06(e). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(c) The Issuers 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 Issuers 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.

(d) Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as provided above, Holdings 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 such date, the Issuers shall also irrevocably deposit with the Trustee or with a paying agent (or, if an Issuer or a Wholly Owned Restricted Subsidiary is acting as the Paying Agent, segregate and hold in trust) an amount equal to the Excess Proceeds to be invested in Cash Equivalents, as directed in writing by Holdings and to be held for payment 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 “Offer Period”), the Issuers 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 Issuers. 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 Issuers to the Trustee are greater than the purchase price of the Notes tendered, the Trustee shall deliver the excess to the Issuers immediately after the expiration of the Offer Period for application in accordance with this Section 4.06.

(e) Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuers 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 an Issuer receives not later than one Business Day prior to the purchase date, a facsimile or electronic 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 Offer Period more Notes (and such Pari Passu Indebtedness) are tendered pursuant to an Asset Sale Offer than the Issuers are required to purchase, selection of such Notes for purchase shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed, or if such Notes are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that no 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.

(f) Notices of an Asset Sale Offer shall be mailed by first class mail, postage prepaid, at least 30 but not more than 60 days before the purchase date to each holder of Notes at such holder’s registered address. 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) Holdings shall not, and shall not permit any of the 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 Holdings (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration in excess of $15.0 million, unless:

(vii) the existence of, or the performance by Holdings or any Restricted Subsidiary of its obligations under the terms of any stockholders or limited liability company agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Issue Date, and any transaction, agreement or arrangement described in the Offering Memorandum and, in each case, any amendment thereto or similar transactions, agreements or arrangements which it may enter into thereafter; provided, however, that the existence of, or the performance by Holdings or any Restricted Subsidiary of its obligations under, any future amendment to any such existing transaction, agreement or arrangement or under any similar transaction, agreement or arrangement entered into after the Issue Date shall only be permitted by this clause (vii) to the extent that the terms of any such existing transaction, agreement or arrangement together with all amendments thereto, taken as a whole, or new transaction, agreement or arrangement are not otherwise more disadvantageous to the holders of the Notes in any material respect than the original transaction, agreement or arrangement as in effect on the Issue Date;

In the event that at the time of such Change of Control Triggering Event, the terms of the Bank Indebtedness restrict or prohibit the repurchase of Notes pursuant to this Section 4.08, then prior to the mailing 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 Triggering Event, the Issuers 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 Triggering Event, except to the extent that the Issuers have exercised their right to redeem the Notes in accordance with Article III of this Indenture, the Issuers shall mail a notice (a “Change of Control Offer”) to each holder with a copy to the Trustee (or deliver a notice pursuant to the procedures of DTC) stating:

(f) Notwithstanding the foregoing provisions of this Section 4.08, the Issuers shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (i) 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 Issuers and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer; (ii) notice of redemption of all outstanding Notes has been given pursuant to Section 3.05, unless and until there is a default in payment of the applicable redemption price; or (iii) in connection with or in contemplation of any Change of Control, the Issuers have made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and have purchased all Notes properly tendered in accordance with the terms of the Alternate Offer.

(g) Notes repurchased by the Issuers 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 Issuers. Notes purchased by a third party pursuant to the preceding clause (f) will have the status of Notes issued and outstanding.

(k) The Issuers 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. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached their obligations under this Section by virtue of such compliance.

SECTION 4.09 Compliance Certificate. Holdings shall deliver to the Trustee within 120 days after the end of each fiscal year of Holdings, beginning with the fiscal year ending on December 31, 2013, an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of Holdings they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period. If any Officer does, the certificate shall describe the Default, its status and what action the Issuers are taking or propose to take with respect thereto. The Issuers also shall comply with Section 314(a)(4) of the TIA. Except with respect to receipt of payments of principal and interest on the Notes and any Default or 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 Issuers’ compliance with or the breach of any representation, warranty or covenant made in this Indenture.

SECTION 4.12 Liens.

(a) Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist any Lien (except Permitted Liens) on any asset or property of Holdings or such Restricted Subsidiary securing Indebtedness of Holdings or a Restricted Subsidiary unless the Notes are equally and ratably secured with (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes) the obligations so secured until such time as such obligations are no longer secured by a Lien.

(b) Section 4.12(a) shall not require Holdings or any of its Restricted Subsidiaries to secure the Notes if the Lien consists of a Permitted Lien. Any Lien that is granted to secure the Notes or any Subsidiary Guarantee under Section 4.12(a) shall be automatically released and discharged at the same time as the release of the Lien that gave rise to the obligation to secure the Notes or such Subsidiary Guarantee under such Section 4.12(a).

(c) For purposes of determining compliance with this Section 4.12, (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 4.12(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” or pursuant to Section 4.12(a), Holdings 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 covenant 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 or pursuant to Section 4.12(a).

(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 shall mean 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 Holdings, 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 4.13 [Intentionally Omitted].

SECTION 4.14 Maintenance of Office or Agency.

(a) The Issuers 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 Issuers 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 Issuers 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 14.01.

(b) The Issuers 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 an Issuer of its obligation to maintain an office or agency for such purposes. The Issuers 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 Issuers hereby designates the Corporate Trust Office of the Trustee or its agent as such office or agency of the Issuers in accordance with Section 2.04.

SECTION 4.15 Covenant Suspension. 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 under this Indenture, 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”), and subject to the provisions of the following paragraph, the Issuers and the Restricted Subsidiaries shall not be subject to Sections 4.03, 4.04, 4.05, 4.06, 4.07, 4.11 and 5.01(a)(iv) (collectively the “Suspended Covenants”).

In the event that Holdings 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 Holdings and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. No Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture, the Notes or the Subsidiary Guarantees with respect to the Suspended Covenants based on, and neither Holdings nor any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period, or any actions taken at any time pursuant to any

contractual obligation arising during the Suspension Period, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period.

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) and (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) and (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). As described above, however, no Default or Event of Default will be deemed to have occurred on the Reversion Date as a result of any actions taken by Holdings or its Restricted Subsidiaries during the Suspension Period. Within 30 days of such Reversion Date, the Issuers must comply with the terms of Section 4.11.

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

(i) Holdings is the surviving person or the Person formed by or surviving any such consolidation, amalgamation, merger, winding up or conversion (if other than Holdings) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a corporation, partnership or limited liability company organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (Holdings or such Person, as the case may be, being herein called the “Successor Holdco”); provided that in the case where the surviving Person is not a corporation, a co-obligor of the Notes is a corporation;

(ii) the Successor Holdco (if other than Holdings) expressly assumes all the obligations of Holdings under this Indenture pursuant to supplemental indentures;

(iii) immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Holdco, or any Restricted Subsidiary as a result of such transaction as having been Incurred by the Successor Holdco, or such Issuer or such Restricted Subsidiary at the time of such transaction) no Default shall have occurred and be continuing;

(iv) immediately after giving pro forma effect to such transaction, as if such transaction had occurred at the beginning of the applicable four-quarter period (and treating any Indebtedness which becomes an obligation of the Successor Holdco, or any Restricted Subsidiary as a result of such transaction as having been Incurred by the Successor Holdco, or such Restricted Subsidiary at the time of such transaction), either

(1) the Successor Holdco would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.03(a); or

This Article V will not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among Holdings and the Restricted Subsidiaries.

(b) Subject to the provisions of Section 12.02(b)(i), no Subsidiary Guarantor shall, and Holdings shall not permit any Subsidiary Guarantor to, consolidate, amalgamate or merge with or into or wind up into (whether or not such Subsidiary Guarantor is the surviving

ARTICLE VI

DEFAULTS AND REMEDIES

SECTION 6.01 Events of Default. An “Event of Default” occurs with respect to Notes if:

(a) there is a default in any payment of interest (including any Additional Interest) on any Note when the same becomes due and payable, and such default continues for a period of 30 days,

(b) there is a default in the payment of principal or premium, if any, of any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise,

(c) there is a failure by Holdings for 180 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) to comply with any of its obligations, covenants or agreements in Section 4.02,

(d) there is a failure by Holdings or any Restricted Subsidiary for 60 days after written notice given by the Trustee or the holders of not less than 30% in principal amount of the Notes then outstanding (with a copy to the Trustee) to comply with its other obligations, covenants or agreements (other than a default referred to in clauses (a), (b) and (c) above) contained in the Notes or this Indenture,

(e) there is a failure by Holdings or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay any Indebtedness (other than Indebtedness owing to Holdings or a Restricted Subsidiary) within any applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds $75.0 million or its foreign currency equivalent,

(f) Holdings or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) pursuant to or within the meaning of any Bankruptcy Law:

(i) commences a voluntary case;

(ii) consents to the entry of an order for relief against it in an involuntary case;

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property; or

(iv) makes a general assignment for the benefit of its creditors or takes any comparable action under any foreign laws relating to insolvency,

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

(i) is for relief against Holdings or any Significant Subsidiary in an involuntary case;

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

(iii) orders the winding up or liquidation of Holdings 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 Holdings or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $75.0 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, or

(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 an 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.

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) or (d) above shall not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of outstanding Notes notify the Issuers of the default and the Issuers do not cure such default within the time specified in clauses (c) or (d) hereof after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” Holdings shall deliver to the Trustee, within five Business Days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which is, or with the giving of notice or the lapse of time or both would become, an Event of Default, its status and what action the Issuers are taking or propose to take with respect thereto.

The term “Bankruptcy Law” means Xxxxx 00, Xxxxxx Xxxxxx 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) hereof with respect to Holdings) occurs with respect to the Notes 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 Issuers may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. Upon 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 Holdings occurs, the principal of, premium, if any, and interest on all the Notes will become immediately due and payable without any declaration or other act on the part of the Trustee or any holders. Under certain circumstances, the holders of a majority in principal amount of outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

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 Holdings 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.

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.

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 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 Issuers, 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 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, if the Trustee, being advised by counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine that the action or proceeding so directed would involve the Trustee in personal liability or expense for which it is not adequately indemnified, or subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other holder or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it against all losses and expenses caused by taking or not taking such action.

SECTION 6.06 Limitation on Suits.

(a) No holder may pursue any remedy with respect to this Indenture 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 the Trustee 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 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 Rights of the Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any holder to receive payment of principal of and interest on the Notes held by such holder, on or after the respective due dates expressed or provided for in the Notes, 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 Issuers 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 the amounts provided for in Section 7.07.

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 Issuers, the Subsidiary 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 under Section 7.07. 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.

SECTION 6.10 Priorities. Any money or property collected by the Trustee pursuant to this Article VI and any other money or property distributable in respect of the Issuers’ or any Subsidiary Guarantor’s obligations under this Indenture after an Event of Default shall be applied in the following order:

FIRST: to the Trustee for amounts due hereunder;

SECOND: to the holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and interest, respectively; and

THIRD: to the Issuers or, to the extent the Trustee collects any amount for any Subsidiary Guarantor, to such Subsidiary Guarantor.

The Trustee may fix a record date and payment date for any payment to the holders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each holder and the Issuers a notice that states the record date, the payment date and the amount to be paid.

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 Issuers nor any Subsidiary 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 Issuers and the Subsidiary 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.

(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 of the Trustee, and such notice references the Notes and this Indenture.

(l) The Trustee may request that the Issuers 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 Issuers or their 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 Section 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 Subsidiary Guarantees or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuers or any Subsidiary 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) or (i) or of the identity of any Significant Subsidiary unless either (a) a Trust Officer shall have actual knowledge thereof or (b) the Trustee shall have received written notice thereof in accordance with Section 14.02 hereof from the Issuers, any Subsidiary 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 Issuers 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 or the Trustee, the Trustee shall mail to each holder of the Notes notice of the Default within the earlier of 90 days after it occurs or 30 days after it is actually known to a Trust Officer or written notice if it is received by the Trustee. 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. Holdings 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. Holdings 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 Holdings is taking or proposes to take in respect thereof.

SECTION 7.06 Reports by Trustee to the Holders. As promptly as practicable after each November 1 beginning with the November 1 following the date of this Indenture, and in any event prior to December 1 in each year, the Trustee shall mail to each holder a brief report dated as of such November 1 that complies with Section 313(a) of the TIA if and to the extent required thereby. The Trustee shall also comply with Section 313(b) of the TIA.

Pursuant to Section 313(d) of the TIA, a copy of each report at the time of its mailing to the holders shall be filed with the SEC and each stock exchange (if any) on which the Notes are listed if the Notes are listed. Holdings agrees to notify promptly the Trustee whenever the Notes become listed on any stock exchange and of any delisting thereof. All reports pursuant to this Section 7.06 shall be provided in accordance with Section 313(c) of the TIA.

SECTION 7.07 Compensation and Indemnity. The Issuers shall pay to the Trustee from time to time compensation for the Trustee’s acceptance of this Indenture and its services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers shall reimburse the Trustee 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 agents, counsel, accountants and experts. The Issuers and the Subsidiary Guarantors, jointly and severally, shall indemnify the Trustee or any predecessor Trustee 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 Subsidiary Guarantee against any Issuer or any Subsidiary Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by any Issuer, any Subsidiary 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. The Trustee shall notify the Issuers of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Issuers shall not relieve any Issuer or any Subsidiary Guarantor of its indemnity obligations hereunder. The Issuers shall defend the claim and the indemnified party shall provide reasonable cooperation at the Issuers’ expense in the defense. Such indemnified parties may have separate counsel and the Issuers and such Subsidiary Guarantor, as applicable, shall pay the fees and expenses of such counsel; provided, however, that the Issuers 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 Issuers and the Subsidiary Guarantor, as applicable, and such parties in connection with such defense. The Issuers 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, negligence or bad faith.

To secure the Issuers’ and the Subsidiary Guarantors’ payment obligations in this Section 7.07, 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.

The Issuers’ and the Subsidiary Guarantors’ payment obligations pursuant to this Section 7.07 shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any Bankruptcy Law or the resignation or removal of the Trustee. Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee Incurs expenses after the occurrence of a Default specified in Section 6.01(f) or (g) with respect to the Issuers, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise Incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not assured to its satisfaction.

SECTION 7.08 Replacement of Trustee.

(a) The Trustee may resign at any time by so notifying the Issuer. The holders of a majority in principal amount of the Notes may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Issuers shall remove the Trustee if:

(ii) the Trustee is adjudged bankrupt or insolvent;

(iii) a receiver or other public officer takes charge of the Trustee or its property; or

(iv) the Trustee otherwise becomes incapable of acting.

(c) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.07.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the holders of 10% in principal amount of

the Notes may petition at the expense of the Issuers any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in Section 310(b) of the TIA, any holder who has been a bona fide holder of a Note for at least six months may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) Notwithstanding the replacement of the Trustee pursuant to this Section, the Issuer’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

SECTION 7.09 Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have.

SECTION 7.10 Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Section 310(a) of the TIA. The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with Section 310(b) of the TIA, subject to its right to apply for a stay of its duty to resign under the penultimate paragraph of Section 310(b) of the TIA; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the TIA any series of securities issued under this Indenture and any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuers are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met.

SECTION 7.11 Preferential Collection of Claims Against the Issuers. The Trustee shall comply with Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated.

ARTICLE VIII

DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.01 Discharge of Liability on Notes; Defeasance.

(a) This Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights and immunities of the Trustee and rights of registration or of transfer or exchange of Notes, as expressly provided for in this Indenture) as to all outstanding Notes when:

(i) either (A) all the Notes theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from such trust) have been delivered to the Trustee for cancellation or (B) all of the Notes (1) have become due and payable, (2) will become due and payable at their stated maturity within one year or (3) if redeemable at the option of the Issuers, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuers, and the Issuers have irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit together with irrevocable instructions from the Issuers directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; provided that if such redemption is made as provided in the second paragraph of Paragraph 5 of the Note (x) the amount of cash in U.S. dollars, non-callable Cash Equivalents, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money in trust on the redemption date as necessary to pay the Applicable Premium as determined by such date;

(ii) the Issuers and/or the Subsidiary Guarantors have paid all other sums payable under this Indenture; and

(iii) the Issuers have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with.

(b) Subject to Sections 8.01(c) and 8.02, the Issuers at any time may terminate (i) all of their obligations under the Notes and this Indenture with respect to the holders of the Notes (“legal defeasance option”), and (ii) their obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.11, 4.12 and 4.15 and the operation of Section 5.01 for the benefit of the holders of the Notes, and Sections 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g) (in the case of Sections 6.01(f) and 6.01(g) with respect to Significant Subsidiaries of the Issuers only), 6.01(h) and 6.01(i) (“covenant defeasance option”).

100

option notwithstanding their prior exercise of their covenant defeasance option. In the event that the Issuers terminate all of their obligations under the Notes and this Indenture (with respect to such Notes) by exercising their legal defeasance option or their covenant defeasance option, the obligations of each Subsidiary Guarantor with respect to its Subsidiary Guarantee shall be terminated simultaneously with the termination of such obligations.

If the Issuers exercises their legal defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of Default. If the Issuers exercise their covenant defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of Default specified in Sections 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g) (with respect to Significant Subsidiaries of Holdings only), 6.01(h) and 6.01(i) or because of the failure of Holdings to comply with Section 5.01.

Upon satisfaction of the conditions set forth herein and upon request of the Issuers, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuers terminate.

(c) Notwithstanding clauses (a) and (b) above, the Issuers’ obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08 and 2.09 and Article VII, including, without limitation, Sections 7.07, 7.08 and 7.09, and in this Article VIII and the rights and immunities of the Trustee under this Indenture shall survive until the Notes have been paid in full. Thereafter, the Issuers’ obligations in Sections 7.07, 7.08, 8.05 and 8.06 and the rights and immunities of the Trustee under this Indenture shall survive such satisfaction and discharge.

SECTION 8.02 Conditions to Defeasance.

(a) The Issuers may exercise their legal defeasance option or their covenant defeasance option only if:

(i) the Issuers irrevocably deposit in trust with the Trustee cash in U.S. Dollars, U.S. Government Obligations or a combination thereof sufficient, or a combination thereof sufficient, to pay the principal of and premium (if any) and interest on the Notes when due at maturity or redemption, as the case may be; provided that if such redemption is made as provided in the second paragraph of Paragraph 5 of the Note (x) the amount of cash in U.S. dollars, non-callable Cash Equivalents, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money in trust on the redemption date as necessary to pay the Applicable Premium as determined by such date;

(ii) the Issuers deliver to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal, premium, if any, and interest when due on all the Notes to maturity or redemption, as the case may be;

101

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

(iv) the deposit does not constitute a default under any other material agreement or instrument binding on the Issuers;

(v) in the case of the legal defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel stating that (1) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling, or (2) since the date of this Indenture there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred. Notwithstanding the foregoing, the Opinion of Counsel required by the immediately preceding sentence with respect to a legal defeasance need not be delivered if all of the Notes not theretofore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due and payable at their Stated Maturity within one year under arrangements for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer;

(vi) such exercise does not impair the right of any holder to receive payment of principal of, premium, if any, and interest on such holder’s Notes on or after the due dates therefore or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes;

(vii) in the case of the covenant defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect that the holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; and

(viii) the Issuers deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Notes to be so defeased and discharged as contemplated by this Article VIII have been complied with.

102

SECTION 8.04 Repayment to Issuer. Each of the Trustee and each Paying Agent shall promptly turn over to the Issuers upon request any money or U.S. Government Obligations held by it as provided in this Article VIII that, in the written opinion of a nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall only be required if U.S. Government Obligations have been so deposited), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article VIII.

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Issuers 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 Issuers for payment as general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

SECTION 8.05 Indemnity for U.S. Government Obligations. The Issuers shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

If the Trustee or any Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article VIII by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ obligations under this Indenture and the Notes so discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or any Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article VIII; provided, however, that, if the Issuers have made any payment of principal of, or interest on, any such Notes because of the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or any Paying Agent.

ARTICLE IX

The failure to give such notice to all holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01.

SECTION 9.02 With Consent of the Holders. The Issuers and the Trustee may amend this Indenture, the Notes and the Subsidiary Guarantees with the consent of the Issuers and the holders of at least a majority in principal amount of the Notes then outstanding

104

After an amendment under this Section 9.02 becomes effective, the Issuers shall mail, or otherwise deliver in accordance with the procedures of the Depositary, to the holders a notice briefly describing such amendment. The failure to give such notice to all holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

(a) A consent to an amendment or a waiver by a holder of a Note shall bind the holder and every subsequent holder of that Note or portion of the Note that evidences the same debt as the consenting holder’s Note, even if notation of the consent or waiver is not made on the Note. However, any such holder or subsequent holder may revoke the consent or waiver as to such holder’s Note or portion of the Note if the Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from Holdings certifying that the requisite principal amount of Notes have consented. After an amendment or waiver

105

If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

SECTION 9.04 Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Issuers may require the holder of the Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note regarding the changed terms and return it to the holder. Alternatively, if the Issuers or the Trustee so determine, the Issuers in exchange for the Note shall issue and, upon written order of each Issuer signed by an Officer, the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make the appropriate notation or to issue a new Note shall not affect the validity of such amendment, supplement or waiver.

SECTION 9.05 Trustee to Sign Amendments. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article IX if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment, the Trustee shall be entitled to receive indemnity satisfactory to it and shall be provided with, and (subject to Section 7.01) shall be fully protected in relying upon, (i) an Officers’ Certificate, (ii) an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuers and any Subsidiary Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof, (iii) a copy of the resolution of the Board of Directors, certified by the Secretary or Assistant Secretary of Holdings, authorizing the execution of such amendment, supplement or waiver and (iv) if such amendment, supplement or waiver is executed pursuant to Section 9.02, evidence reasonably satisfactory to the Trustee of the consent of the holders required to consent thereto.

SECTION 9.06 Additional Voting Terms; Calculation of Principal Amount. All Notes issued under this Indenture shall vote and consent together on all matters (as to which any of such Notes may vote) as one class and no Notes will have the right to vote or consent as a separate class on any matter. Determinations as to whether holders of the requisite aggregate principal amount of Notes have concurred in any direction, waiver or consent shall be made in accordance with this Article IX and Section 2.13.

106

SECTION 9.07 Compliance with the Trust Indenture Act. From the date on which this Indenture is qualified under the TIA, every amendment, waiver or supplement to this Indenture or the Notes shall comply with the TIA as then in effect.

(a) Each Subsidiary Guarantor hereby jointly and severally, irrevocably and unconditionally guarantees, on a senior unsecured basis from the Issue Date, as a primary obligor and not merely as a surety, to each holder and to the Trustee 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 Issuers 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 Issuers under this Indenture and the Notes and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuers whether for fees, expenses, indemnification or otherwise under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Subsidiary Guaranteed Obligations”). Each Subsidiary Guarantor further agrees that the Subsidiary Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from any Subsidiary Guarantor, and that each Subsidiary Guarantor shall remain bound under this Article XII notwithstanding any extension or renewal of any Subsidiary Guaranteed Obligation.

(b) Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Issuers of any of the Subsidiary Guaranteed Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Notes or the Subsidiary Guaranteed Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (i) the failure of any holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Issuers 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 or the Trustee for the Subsidiary Guaranteed Obligations or each Subsidiary Guarantor; (v) the failure of any holder or Trustee to exercise any right or remedy against any other guarantor of the Subsidiary Guaranteed Obligations; or (vi) any change in the ownership of each Subsidiary Guarantor, except as provided in Section 12.02(b). Each Subsidiary Guarantor hereby waives any right to which it

107

may be entitled to have its obligations hereunder divided among the Subsidiary Guarantors, such that such Subsidiary Guarantor’s obligations would be less than the full amount claimed.

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

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

(e) The Subsidiary Guarantee of each Subsidiary 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, senior in right of payment to all existing and future Subordinated Indebtedness of such Subsidiary Guarantor and subordinated and subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Secured Indebtedness of the relevant Subsidiary Guarantor and is made subject to such provisions of this Indenture.

(f) Except as expressly set forth in Sections 8.01(b), 12.02 and 12.06, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Subsidiary Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or would otherwise operate as a discharge of any Subsidiary Guarantor as a matter of law or equity.

(g) Each Subsidiary Guarantor agrees that its Subsidiary Guarantee shall remain in full force and effect until payment in full of all the Subsidiary Guaranteed Obligations. Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Subsidiary Guaranteed Obligation is rescinded or must otherwise be restored by any holder or the Trustee upon the bankruptcy or reorganization of the Issuers or otherwise.

108

(h) In furtherance of the foregoing and not in limitation of any other right which any holder or the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Issuers to pay the principal of or interest on any Subsidiary 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 Subsidiary Guaranteed Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the holders or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Subsidiary Guaranteed Obligations, (ii) accrued and unpaid interest on such Subsidiary Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the Issuers to the holders and the Trustee.

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

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

(k) Upon request of the Trustee, each Subsidiary 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 Subsidiary 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 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.

(b) A Subsidiary Guarantee as to any Restricted Subsidiary that is a party hereto on the date hereof or that executes a supplemental indenture in accordance with Section 4.11 hereof and provides a guarantee shall terminate and be of no further force or effect

109

and such Subsidiary Guarantee shall be deemed to be released from all obligations under this Article XII upon:

(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 in a manner not in violation of 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) the release or discharge of the guarantee by such Subsidiary Guarantor of the Credit Agreement or other Indebtedness or the guarantee of any other Indebtedness which resulted in the obligation to guarantee the Notes;

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

(v) such Restricted Subsidiary ceasing to be a Subsidiary as a result of any foreclosure of any pledge or security interest securing Bank Indebtedness or other exercise of remedies in respect thereof; and

(vi) the occurrence of a Covenant Suspension Event.

SECTION 12.03 [Intentionally Omitted].

SECTION 12.04 Successors and Assigns. This Article XII shall be binding upon each Subsidiary 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.

SECTION 12.06 Modification. No modification, amendment or waiver of any provision of this Article XII, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the

110

Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle any Subsidiary 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 Guarantors. Each Subsidiary which is required to become a Subsidiary Guarantor of the Notes pursuant to Section 4.11 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit D 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, Holdings 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 Subsidiary Guarantee on any Note shall not affect or impair the validity thereof.

Beneficial interests in Global Notes shall be transferred or exchanged only for beneficial interests in Global Notes. Transfers and exchanges of beneficial interests in the

Appendix A-4

Global Notes also shall require compliance with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Transfer Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Transfer Restricted Global Note in accordance with the transfer restrictions set forth in the Restricted Notes Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in a Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person. A beneficial interest in an Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “TIA”). 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 Notes are senior unsecured obligations of the Issuers. This Note is one of the Initial Notes referred to in the Indenture. The Notes include the Initial Notes and any Additional Notes. The Initial Notes and any Additional Notes are treated as a single class of securities under the Indenture. The Indenture imposes certain limitations on the ability of Holdings and its Restricted Subsidiaries to, among other things, make certain Investments and other Restricted Payments, pay dividends and other distributions, Incur Indebtedness, enter into consensual restrictions upon the payment of certain dividends and distributions by such Restricted Subsidiaries, issue or sell shares of capital stock of Holdings and such Restricted Subsidiaries, enter into or permit certain transactions with Affiliates, create or Incur Liens and make Asset Sales. The Indenture also imposes limitations on the ability of each 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 Issuers 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 Subsidiary Guarantors have unconditionally guaranteed the Subsidiary Guaranteed Obligations pursuant to the terms of the Indenture and any Subsidiary Guarantor that executes a Subsidiary Guarantee will unconditionally guarantee the Subsidiary Guaranteed Obligations, which such Subsidiary Guarantees shall be on a senior unsecured basis from the Issue Date, pursuant to the terms of the Indenture.

Any such redemption may be conditioned upon the Change of Control occurring if the notice is mailed prior to the Change of Control. If the Issuers exercise

12. Unclaimed Money

If money for the payment of principal or interest remains unclaimed for two years, the Trustee and a Paying Agent shall pay the money back to the Issuers at their written request unless an abandoned property law designates another Person. After any such payment, the holders entitled to the money must look to the Issuers for payment as general creditors and the Trustee and a Paying Agent shall have no further liability with respect to such monies.

13. Discharge and Defeasance

Subject to certain conditions, the Issuers at any time may terminate some of or all their obligations under the Notes and the Indenture if the Issuers deposit with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be.

14. Amendment; Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Notes may be amended with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding Notes and (ii) any past default or compliance with any provisions may be waived with the written consent of the holders of at least a majority in principal amount of the outstanding Notes. Subject to certain exceptions set forth in the Indenture, without the consent of any holder, the Issuers and the Trustee may amend the Indenture, the Notes or the Subsidiary Guarantees (i) to cure any ambiguity, omission, defect or inconsistency; (ii) to provide for the assumption by a Successor (with respect to an Issuer) of the obligations of an Issuer under the Indenture and the Notes; (iii) to provide for the assumption by a Successor Subsidiary Guarantor (with respect to any Subsidiary Guarantor), as the case may be, of the obligations of a Subsidiary Guarantor under the Indenture and its Subsidiary Guarantee; (iv) to provide for uncertificated Notes in addition to or in place of certificated Notes, provided, however, that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code; (v) to conform the text of the Indenture, the Notes or the Subsidiary Guarantees to any provision of the “Description of Notes” in the Offering Memorandum to the extent that such provision in this Indenture, the Notes or the Subsidiary Guarantees was intended by the Issuers to be verbatim recitation of a provision in the “Description of Notes” in the Offering Memorandum; (vi) to add a guarantee or obligor with respect to the Notes; (vii) to release a Subsidiary Guarantee as permitted by the Indenture; (viii) to add to the covenants of the Issuers for the benefit of the holders or to surrender any right or power herein conferred upon the Issuers; (ix) to comply with any requirement of the SEC in connection with qualifying or maintaining the qualification of the Indenture under the TIA; (x) to make any change that does not adversely affect the rights of any holder; or (xi) to make certain changes to the Indenture to provide for the issuance of Additional Notes.

A-11

15. Defaults and Remedies

If an Event of Default (other than a Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuer) occurs and is continuing, the Trustee or the holders of at least 30% in principal amount of outstanding Notes by notice to the Issuers may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest will be due and payable immediately. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuers occurs, the principal of, premium, if any, and interest on all the Notes will become immediately due and payable without any declaration or other act on the part of the Trustee or any holders. Under certain circumstances, the holders of a majority in principal amount of outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

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 at the 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. No holder may pursue any remedy with respect to the Indenture unless (i) such holder has previously given the Trustee notice that an Event of Default is continuing, (ii) holders of at least 30% in principal amount of the outstanding Notes have requested the Trustee 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 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 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 against all losses and expenses caused by taking or not taking such action.

16. Trustee Dealings with the Issuers

Subject to certain limitations imposed by the TIA, 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 Issuers or their Affiliates and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee.

17. No Recourse Against Others

No director, officer, employee, manager, incorporator or holder of any Equity Interests in an Issuer or any Subsidiary Guarantor or any direct or indirect parent companies, as

A-12

such, will have any liability for any obligations of an Issuer or any Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary 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.

21. Governing Law

22. CUSIP Numbers; ISINs

Ladies and Gentlemen:

This certificate is delivered to request a transfer of $[ ] principal amount of the 73/8% Senior Notes due 2021 (the “Notes”) of [ATHLON HOLDINGS LP] and [ATHLON FINANCE CORP.] (collectively with their successors and assigns, the “Issuers”).

The undersigned represents and warrants to you that:

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $100,000 principal amount of the Notes, and we are acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Notes, and we invest in or purchase securities similar to the Notes in the normal course of our business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment.

2. We understand that the Notes have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is two years after the later of the date of original issue and the last date on which either of the Issuers or any affiliate of such Issuers was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) in the United States to a person whom we reasonably believe is a qualified institutional buyer (as defined in rule 144A under the Securities Act) in a

transaction meeting the requirements of Rule 144A, (b) outside the United States in an offshore transaction in accordance with Rule 904 of Regulation S under the Securities Act, (c) pursuant to an exemption from registration under the Securities Act provided by Rule 144 thereunder (if applicable) or (d) pursuant to an effective registration statement under the Securities Act, in each of cases (a) through (d) in accordance with any applicable securities laws of any state of the United States. In addition, we will, and each subsequent holder is required to, notify any purchaser of the Note evidenced hereby of the resale restrictions set forth above. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made to an institutional “accredited investor” prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Issuers and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Notes for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Issuers and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Notes pursuant to clause 1(b), 1(c) or 1(d) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Issuers and the Trustee.
