“144 A Global Note” means a global note substantially in the form of Exhibit A1 hereto bearing the Global Note Legend and the Private Placement Legend and deposited with or on behalf of, and registered in the name of, the Depositary or its nominee that shall be issued in a denomination equal to the outstanding principal amount of the Notes sold in reliance on Rule 144A.

“Acquired Debt” means Indebtedness of a Person (1) existing at the time such Person becomes a Restricted Subsidiary or (2) assumed in connection with the acquisition of assets from such Person, in each case, other than Indebtedness incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary or such acquisition, as the case may be. Acquired Debt shall be deemed to be incurred on the date of the related acquisition of assets from any Person or the date the acquired Person becomes a Restricted Subsidiary, as the case may be.

“Additional Assets” means (i) any assets or property (other than cash, Cash Equivalents or securities) used in the Oil and Gas Business or any business ancillary thereto, (ii) Investments in any other Person engaged in the Oil and Gas Business or any business ancillary thereto (including the acquisition from third parties of Capital Stock of such Person) as a result of which such other Person becomes a Restricted Subsidiary, (iii) the acquisition from third parties of Capital Stock of a Restricted Subsidiary, (iv) Permitted Business Investments, (v) capital expenditures by the Parent Guarantor, the Company or a Restricted Subsidiary in the Oil and Gas Business or (vi) 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 (ii) and (vi), such Restricted Subsidiary is primarily engaged in the Oil and Gas Business.

“Additional Interest” means any additional interest payable pursuant to a Registration Rights Agreement.

“Additional Notes” means any further Notes (other than the Initial Notes issued on the Issue Date and other than any Exchange Notes issued in exchange for outstanding Notes

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

(a) the sum of

(i) discounted future net revenues from proved oil and gas reserves of the Parent Guarantor, the Company and the Restricted Subsidiaries calculated in accordance with Commission guidelines before any state or federal income taxes, as estimated by the Parent Guarantor in a reserve report prepared as of the end of the Parent Guarantor’s 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 (1) estimated proved oil and gas reserves acquired since such year-end, which reserves were not reflected in such year-end reserve report, and (2) estimated oil and gas reserves attributable to extensions, discoveries and other additions and upward revisions of estimates of proved oil and gas reserves since such year-end due to exploration, development or exploitation, production or other activities, which would, in accordance with standard industry practice, cause such revisions (including the impact to proved reserves and future net revenues from estimated development costs incurred and the accretion of discount since such year-end), and decreased by, as of the date of determination, the estimated discounted future net revenues from (3) estimated proved oil and gas reserves produced or disposed of since such year-end and (4) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since such year-end due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions, in each case calculated on a pre-tax basis in accordance with Commission guidelines , in the case of the foregoing clauses (1) through (4) utilizing the prices and costs calculated in accordance with Commission guidelines as if the end of the most recent fiscal quarter preceding the date of determination for which such information is available to the Parent Guarantor were year-end; provided, however, that, in the case of each of the determinations made pursuant to the foregoing clauses (1) through (4), such increases and decreases shall be as estimated by the Parent Guarantor’s petroleum engineers,

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

(iii) the Net Working Capital of the Parent Guarantor, the Company and the Restricted Subsidiaries on a date no earlier than the date of the Parent Guarantor’s latest annual or quarterly financial statements, and

(iv) the greater of (1) the net book value of other tangible assets of the Parent Guarantor, the Company and the Restricted Subsidiaries as of a date no earlier than the date of the Parent Guarantor’s latest annual or quarterly financial statements and (2) the appraised value, as estimated by independent appraisers, of other tangible assets of the Parent Guarantor, the Company and the Restricted Subsidiaries, as of a date no earlier than the date of the Parent Guarantor’s latest audited financial statements; provided that, if no such appraisal has been obtained, the Parent Guarantor shall not be required to obtain such an appraisal and only clause (iv)(1) of this definition shall apply,

minus (b) the sum of

(i) Minority Interests,

(ii) any net gas balancing liabilities of the Parent Guarantor, the Company and the Restricted Subsidiaries, as reflected in the Parent Guarantor’s latest annual or quarterly balance sheet, to the extent not deducted in calculating Net Working Capital of the Parent Guarantor in accordance with clause (a)(iii) of this definition,

(iii) to the extent included in (a)(i) above, the discounted future net revenues, calculated in accordance with Commission guidelines (but utilizing prices and costs calculated in accordance with Commission guidelines as if the end of the most recent fiscal quarter preceding the date of determination for which such information is available to the Parent Guarantor were year-end), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Parent Guarantor, the Company and the Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and

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

For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Company; provided that such officer may in his or her discretion include any reasonably identifiable and factually supportable pro forma changes to Consolidated Net Income (Loss), including any pro forma expenses and cost reductions, that have occurred or in the judgment of such officer are reasonably expected to occur within 12

(1) in making such computation, the Consolidated Interest Expense attributable to interest on any Indebtedness computed on a pro forma basis and (A) bearing a floating interest rate shall be computed as if the average rate in effect for the period had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof) and (B) bearing an interest rate (x) at the option of the Parent Guarantor, the Company or any Restricted Subsidiary, the interest rate shall be calculated by applying such optional rate chosen by the Parent Guarantor, the Company or such Restricted Subsidiary or (y) that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank offered rate or other rate, shall be calculated based upon the rate actually chosen, or if none, then based upon such optional rate chosen as the Parent Guarantor, the Company or such Restricted Subsidiary may designate, and

(d) If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

Section 2.04 Registrar and Paying Agent.

(a) The Company shall maintain in the continental United States an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange (the “Securities Register”). The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without prior notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such.

The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal or premium, if any, or interest on the Notes, and shall notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or one of its Subsidiaries) shall have no further liability for the money. If the Company or any of its Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Notes.

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 all Holders and shall otherwise comply with TIA Section 312(a).

Section 2.07 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes shall be exchanged by the Company for Definitive Notes if (i) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary; or (ii) there shall have occurred and be continuing an Event of Default and the Depositary notifies the Trustee of its decision to exchange the Global Notes for Definitive Notes; provided that a beneficial interest in the Regulation S Temporary Global Note may not be exchanged for Definitive Notes or transferred to a Person who takes delivery thereof in the form of a Definitive Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act. Except as provided in the preceding sentence, and notwithstanding any contrary indication this Section 2.07, beneficial interests in a Global Note may be exchanged for Definitive Notes only with the consent of the Company upon delivery of a written notice to such effect to the Trustee, including if an affiliate (as defined in Rule 144) of the Company acquires such interests. Upon the occurrence of any of the preceding events in (i) or (ii) above or upon the consent of the Company as provided in the preceding sentence, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.08, 2.11, 3.06, 4.11(h), 4.17(c) and 9.05. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.07 or Sections 2.08, 2.11, 3.06, 4.11(h), 4.17(c) or 9.05, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.07(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.07(b), (c) or (f). Whenever any provision herein (including Sections 3.06, 4.11 or 4.17) refers to issuance by the Company and authentication and delivery by the Trustee of a new Note in exchange for the portion of a surrendered Note that has not been redeemed or repurchased, as the case may be, in lieu of the surrender of any Global Note and the issuance, authentication and delivery of a new Global Note in exchange therefor, the Trustee or the Depositary at the direction of the Trustee may endorse such Global Note to reflect a reduction in the principal amount represented thereby in the amount of Notes so represented that have been so redeemed or repurchased.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Participants and Indirect Participants shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary or by the Trustee as the Custodian with respect to the Global Notes, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written

certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants or the Indirect Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Note. Subject to the provisions of this Section 2.07 and Section 12.14, the Holder of a Global Note shall be entitled to grant proxies and otherwise authorize any Person, including Participants and Indirect Participants and Persons that may hold interests through such Persons, to take any action that a Holder is entitled to take under this Indenture or the Notes. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the 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 Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend and any Applicable Procedures; provided, however, that prior to the expiration of the Restricted Period, (x) transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than a “distributor” (as defined in Rule 902(d) of Regulation S)) and (y) such beneficial interests may be held only through Euroclear or Clearstream (as Participants in the Depositary). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. Except as may be required by any Applicable Procedures, no written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.07(b)(i).

(ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.07(b)(i) above, the transferor of such beneficial interest shall deliver to the Registrar either (A) (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase or (B) (1) if permitted under Section 2.07(a), a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (B)(1) above; provided that in no event shall Definitive Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S Temporary Global Note prior to (x) the expiration of the Restricted Period and (y) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act; provided further that until the expiration of the Restricted Period a beneficial interest in a

Restricted Global Note representing a Regulation S Global Note may be transferred to a Person who takes delivery in the form of an interest in a Restricted Global Note representing a Rule 144A Global Note only if the transferor first delivers to the Registrar, in accordance with Section 2.7(b)(iii)(A) a written certificate (in the form provided in Exhibit B hereto, including the certifications in item (1) thereof); after the expiration of the Restricted Period, such certification requirements shall not apply to such transfers of beneficial interests in a Restricted Global Note representing a Regulation S Global Note (subject to compliance with the Applicable Procedures and the restrictions set forth in the Private Placement Legend). Upon consummation of an Exchange Offer by the Company in accordance with Section 2.07(f), the requirements of this Section 2.07(b)(ii) shall be deemed to have been satisfied upon receipt by the Registrar of the instructions contained in the Letter of Transmittal delivered by the Holder of such beneficial interests in the Global Notes.

(iv) Transfer and Exchange of Beneficial Interests in a Restricted Global Note for Beneficial Interests in an Unrestricted Global Note. A beneficial interest in any Restricted Global Note may be exchanged by any Holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer complies with the requirements of Section 2.07(b)(ii) above and:

Upon receipt of a request to register such a transfer, the Registrar shall register the Unrestricted Definitive Notes pursuant to the instructions from the Holder thereof.

(f) Exchange Offer. Upon the occurrence of an Exchange Offer in accordance with the applicable Registration Rights Agreement, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee shall authenticate (A) one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of the beneficial interests in the applicable Global Notes (1) tendered for acceptance by Persons that make any and all certifications in the applicable Letters of Transmittal (or are deemed to have made such certifications if delivery is made through the Applicable Procedures) as may be required by such Registration Rights Agreement and (2) accepted for exchange in such Exchange Offer and (B) Unrestricted Definitive Notes in an aggregate principal amount equal to the aggregate principal amount of the Definitive Notes tendered for acceptance by Persons who made the foregoing certifications and accepted for exchange in the Exchange Offer. Concurrently with the issuance of such Notes, the Trustee shall reduce or cause to be reduced in a corresponding amount the aggregate principal amount of the applicable Global Notes so accepted for exchange, and the Company shall execute and, upon receipt of an Authentication Order in accordance with Section 2.02, the Trustee shall authenticate and deliver to the Persons designated by the Holders of Definitive Notes so accepted

Unrestricted Definitive Notes in the appropriate aggregate principal amount. Any Notes that remain outstanding after the consummation of an Exchange Offer, and Exchange Notes issued in connection with an Exchange Offer, shall be treated as a single class of securities under this Indenture.

(g) Legends. The following legends shall appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless specifically stated otherwise in the applicable provisions of this Indenture.

(i) Private Placement Legend. Except as permitted below, each Global Note and each Definitive Note (and all Notes issued in exchange therefor or substitution thereof) shall bear the legend in substantially the following form:

THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER XXXXXXX 0 XX XXX XXXXXX XXXXXX SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (i) (a) TO A PERSON WHO IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (b) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT, (c) OUTSIDE THE UNITED STATES TO A NON-U.S. PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT, OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL IF THE COMPANY SO REQUESTS), (ii) TO THE COMPANY, OR (iii) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN CLAUSE (A) ABOVE. NO REPRESENTATION CAN BE MADE AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR THE RESALE OF THE SECURITY EVIDENCED HEREBY.

Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to subparagraph (b)(iv), (c)(iii), (c)(iv), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) of this Section 2.07 (and all Notes issued in exchange therefor or substitution thereof) (and any Note not required by law to have such a legend), shall not bear the Private Placement Legend.

In addition, the foregoing legend may be adjusted for future issuances in accordance with applicable law. The Company, acting in its discretion, may remove the Private Placement Legend from any Restricted Global Note at any time on or after the Resale Restriction Termination Date applicable to such Note. Without limiting the generality of the preceding sentence, the Company may, subject to Applicable Procedures, effect such removal by issuing and delivering, in exchange for such Note, an Unrestricted Global Note without such legend, registered to the same Holder and in an equal principal amount, and upon receipt by the Trustee of a written order of the Company stating that the Resale Restriction Termination Date applicable to such Note has occurred and requesting the authentication and delivery of an Unrestricted Global Note in exchange therefor (which order shall not be required to be accompanied by any Opinion of Counsel or any other document) given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date), the Trustee shall authenticate and deliver such Unrestricted Global Note to the Depositary or pursuant to such Depositary’s instructions or hold such Unrestricted Global Note as Custodian for the Depositary and shall request the Depositary to, or, if the Trustee is Custodian of such Restricted Global Note, shall itself, surrender such Restricted Global Note in exchange for such Unrestricted Global Note without such legend and thereupon cancel such Restricted Global Note so surrendered, all as directed in such order. For purposes of determining whether the Resale Restriction Termination Date has occurred with respect to any Restricted Global Note or delivering any order pursuant to this Section 2.07(g)(i) with respect to such Restricted Global Notes, (i) only those Restricted Global Notes that a Principal Officer of the Company actually knows (after reasonable inquiry) to be or to have been owned by an Affiliate of the Company shall be deemed to be or to have been, respectively, owned by an Affiliate of the Company; and (ii) “Principal Officer” means the principal executive officer, the principal financial officer, the treasurer or the principal accounting officer of the Company. For purposes of this Section 2.7(g)(i), all provisions relating to the removal of the Private Placement Legend shall relate, if the Resale Restriction Termination Date has occurred only with respect to a portion of the Notes evidenced by a Restricted Global Note, to such portion of the Notes so evidenced as to which the Resale Restriction Termination Date has occurred.

Each Holder of any Note evidenced by any Restricted Global Note, by its acceptance thereof, (A) authorizes and consents to, (B) appoints the Company as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on such Holder’s behalf, as the Depositary or the Trustee may require to effect, and (C) upon the

request of the Company, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the Depositary or the Trustee may require, or as shall otherwise be necessary to effect, the removal of the Private Placement Legend (including by means of the exchange of all or the portion of such Restricted Global Note evidencing such Note for a certificate evidencing such Note that does not bear such legend) at any time after the Resale Restriction Termination Date.

(ii) Global Note Legend. Each Global Note shall bear a legend in substantially the following form:

THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.07 OF THE INDENTURE, (2) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.07(a) OF THE INDENTURE, (3) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.12 OF THE INDENTURE AND (4) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE COMPANY.

(h) Regulation S Temporary Global Note Legend. The Regulation S Temporary Global Note shall bear a legend in substantially the following form:

THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL NOTE, AND THE CONDITIONS AND PROCEDURES GOVERNING ITS EXCHANGE FOR DEFINITIVE NOTES, ARE AS SPECIFIED IN THE INDENTURE (AS DEFINED HEREIN).

(i) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.12. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such

Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon the Company’s order or at the Registrar’s request.

(ii) No service charge shall be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon any exchange pursuant to Sections 2.07, 2.08, 2.11, 3.06, 4.11(h), 4.17(c) and 9.05 not involving any transfer).

(iii) The Registrar shall not be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

(iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid and legally binding obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(v) The Company shall not be required (A) to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

(vi) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02.

permitted by Section 8-405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code, the Company shall issue and the Trustee shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond shall be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for their expenses in replacing a Note.

(b) Every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

(c) 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, destroyed, lost or wrongfully taken Notes.

Section 2.09 Outstanding Notes.

(a) The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.09 as not outstanding. The aggregate principal amount of any outstanding Global Note that is outstanding at any time shall be such aggregate principal amount of Notes that is endorsed thereon as being represented thereby at such time. Except as set forth in Section 2.10, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

(b) If a Note is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a “protected purchaser” within the meaning of Section 8-405 of the Uniform Commercial Code.

(c) If the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue.

(d) If the Paying Agent (other than the Company, a Subsidiary of the Company or an Affiliate of any of the foregoing) holds, on a redemption date or other Maturity, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.10 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction,

waiver or consent, only Notes that any of its Responsible Officers knows are so owned shall be so disregarded.

Section 2.11 Temporary Notes.

(a) Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Notes.

(b) Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

Section 2.12 Cancellation.

The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and 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, replacement or cancellation and shall dispose of canceled Notes in accordance with its procedures for the disposition of canceled securities in effect as of the date of such disposition (subject to the record retention requirements of the Exchange Act). Certification of the disposition of all canceled Notes shall be delivered to the Company. The Company may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

Section 2.13 Defaulted Interest.

If the Company defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on the record date for the interest payment or a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. The Company may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this sentence, such manner of payment shall be deemed practicable by the Trustee.

Section 2.14 CUSIP Numbers.

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

Section 2.15 Additional Interest.

If Additional Interest is payable by the Company pursuant to an applicable Registration Rights Agreement and paragraph 1 of the Notes, no later than 15 days prior to the proposed payment date for such Additional Interest, the Company shall deliver to the Trustee a certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such interest is payable pursuant to Section 4.01. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the details of such payment.

Section 2.16 Issuance of Additional Notes.

(a) The Company shall be entitled, subject to its compliance with Article Four, to issue Additional Notes under this Indenture.

The Initial Notes, any Additional Notes subsequently issued upon original issue under this Indenture and all Exchange Notes issued in exchange therefor shall be treated as a single class for all purposes under this Indenture, including directions, waivers, amendments, consents, redemptions and offers to purchase; and none of the Holders of any Initial Notes, any Exchange Notes or any Additional Notes shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

(b) With respect to any Additional Notes, the Company shall set forth in a Board Resolution and an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

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

(2) the issue price, the issue date (and the corresponding date from which interest shall accrue thereon and the first interest payment date therefor) and the CUSIP and/or ISIN number of such Additional Notes; and

(3) whether such Additional Notes shall be subject to the restrictions on transfer set forth in Section 2.07 relating to Restricted Global Notes and Restricted Definitive Notes.

Section 2.17 Persons Deemed Owners.

Prior to due presentment of a Note for registration of transfer, the Company, the Trustee, any Agent or any other agent of the Company or the Trustee may treat the Person in whose name such Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and interest on, such Note and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, the Trustee, any Agent nor any other agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.18 Non-Business Day Payments.

If any interest payment date, the Stated Maturity, any redemption date, any Asset Sale Purchase Date or any Change of Control Purchase Date falls on a day that is not a Business Day, then the required payment or delivery will be made on the next succeeding Business Day with the same force and effect as if made on the date that the payment or delivery was due, and no additional interest will accrue on that required payment or delivery for the period from and after the interest payment date, Stated Maturity, redemption date, Asset Sale Purchase Date or Change of Control Purchase Date, as the case may be, to that next succeeding Business Day.

Section 2.19 Computation of Interest.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than three Business Days (unless a shorter period shall be agreeable to the Trustee) prior to the giving of notice of redemption pursuant to Section 3.03 by the Trustee from the outstanding Notes.

Redemptions pursuant to Section 3.07(b) shall be made on a pro rata basis or on as nearly a pro rata basis as practicable (subject to the provisions of DTC or other depositary).

Section 3.03 Notice of Redemption.

(a) At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address and send a copy to the Trustee at the same time, except that optional redemption notices may be mailed more than 60 days prior to a redemption date in connection with a Legal Defeasance or Covenant Defeasance of the Notes or a Satisfaction and Discharge. Any redemption or notice of redemption may, at the Company’s discretion, be subject to one or more conditions precedent and, in the case of redemption pursuant to Section 3.07(b), be given prior to the completion of the related Equity Offering.

The notice shall identify the Notes (including CUSIP and/or ISIN number(s)) to be redeemed and shall state:

(i) the redemption date;

(ii) the redemption price; provided that, for a redemption being effected pursuant to Section 3.07(c), the notice need not set forth the Applicable Premium but only the manner of calculation thereof;

(iii) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion of the original Note shall be issued in the name of the Holder thereof upon cancellation of the original Note;

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

(v) that Notes called for redemption shall be surrendered to the Paying Agent to collect the redemption price and become due on the date fixed for redemption;

The notice, if mailed in the manner provided herein shall be presumed to have been given, whether or not the Holder receives such notice. Failure to give timely notice or any defect in the notice shall not affect the validity of the redemption.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, subject only to any conditions precedent set forth therein.

Section 3.05 Deposit of Redemption Price.

(a) Not later than 12:30 p.m. (New York City time) on the redemption date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary thereof is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.05) money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed.

(b) If the Company complies with the provisions of Section 3.05(a), on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption, unless the redemption is not effective due to the failure of conditions precedent described in the notice of redemption to be fulfilled. If a Note is redeemed on or after

an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Holder in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01.

Section 3.06 Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. No Notes in denominations of $2,000 or less shall be redeemed in part.

At least 65% of the aggregate principal amount of Notes (including the principal amount of any Additional Notes issued under this Indenture) shall remain outstanding immediately after the occurrence of such redemption. In order to effect this redemption, the Company shall complete such redemption no later than 180 days after the closing of the related Equity Offering. Notice of any redemption pursuant to this clause (b) may be given prior to the completion of the applicable Equity Offering, and any such redemption or notice may, at the Company’s discretion, be subject

to one or more conditions precedent, including completion of such Equity Offering. If any such conditions do not occur, the Company will provide prompt written notice to the Trustee rescinding such redemption, and such redemption and notice of redemption shall be rescinded and of no force or effect. Upon receipt of such notice, the Trustee will promptly send a copy of such notice to the Holders of the Notes to be redeemed in the same manner in which the notice of redemption was given.

(c) The Notes may also be redeemed, in whole or in part, at any time or from time to time prior to February 15, 2015 at the option of the Company at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest and Additional Interest, if any, to, the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(d) The Notes may also be redeemed, as a whole, following certain Change of Control Offers, at the redemption price and subject to the conditions set forth in Section 4.17(h).

Section 3.10 No Limit on Other Purchases.

Nothing in this Indenture or the Notes shall prohibit or limit the right of the Company or any Affiliate of the Company from time to time to repurchase the Notes at any price in open market purchases or negotiated transactions or by tender offer or otherwise without any notice to or consent by Holders. Any Notes purchased by the Company may, to the extent permitted by law, be held or resold or may, at the Company’s option, be delivered to the Trustee for cancellation.

(d) Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on its request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall, at the expense of the Company, cause to be published once, in The New York Times or The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 4.03 Reports.

(a) Whether or not required by the rules and regulations of the Commission, so long as any Notes are outstanding, the Parent Guarantor will furnish to Holders of Notes or cause the Trustee to furnish to the Holders of Notes or file with the Commission for public availability:

(1) all quarterly and annual financial information that would be required to be filed with the Commission on Forms 10-Q and 10-K if the Parent Guarantor were required to file such reports, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report thereon by the Parent Guarantor’s independent auditors, which financial information shall be filed within (or prior to effectiveness of an exchange offer registration statement within 15 days after) the time period for such reports specified in the Commission’s rules and regulations; and

(2) after effectiveness of an exchange offer registration statement, within the time periods specified in the Commission’s rules and regulations, the information that would be required to be filed with the Commission in current reports on Form 8-K if the Parent Guarantor were required to file such reports; provided, however, that, in the case of clause (1) or (2), if the last day of any such time period is not a Business Day, such information will be due on the next succeeding Business Day. All such information will be prepared in all material respects in accordance with all of the rules and regulations of the Commission applicable to such information.

(c) This Section 4.03 will not impose any duty on the Company or the Parent Guarantor under the Xxxxxxxx-Xxxxx Act of 2002 and the related Commission rules that would not otherwise be applicable.

(d) For so long as any of the Notes remain outstanding and constitute “restricted securities” under Rule 144 and the Parent Guarantor is not subject to Section 13 or 15(d) of the Exchange Act, the Parent Guarantor will furnish to the Holders of the Notes and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(e) The Parent Guarantor will be deemed to have furnished to the Holders and to prospective investors the information referred to in subclauses (1) and (2) of paragraph (a) of this Section 4.03 or the information referred to in paragraph (b) of this Section 4.03 if the Parent Guarantor has posted such reports or information on the Parent Guarantor or Company Website with access to current and prospective investors. For purposes of this Indenture, the term “Parent Guarantor or Company Website” means the collection of web pages that may be accessed on the World Wide Web using the URL address xxxx://xxx.xxxxxxxxxxx.xxx or such other address as the Parent Guarantor may from time to time designate in writing to the Trustee.

(f) Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.04 Compliance Certificate.

(a) The Parent Guarantor shall deliver to the Trustee, within 120 days after the end of each fiscal year ending after the Issue Date, an Officers’ Certificate stating that a review of the activities of the Parent Guarantor and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Parent Guarantor and the Company have kept, observed, performed and fulfilled their respective obligations under this Indenture and further stating, as to each such Officer signing such certificate, that to the best of his or her actual knowledge, each of the Parent Guarantor and the Company has kept, observed, performed and fulfilled its obligations under this Indenture and is not in default in the performance or observance of any of the material terms, provisions and conditions of this Indenture, in each case, so as not to result in any Default or Event of Default (or, if a Default or Event of Default shall have occurred and be continuing,

describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or propose to take with respect thereto).

(b) The Parent Guarantor shall, so long as any of the Notes are outstanding, deliver to the Trustee, on or before the 30th day after it becomes aware of the occurrence and continuance of any Default or Event of Default, unless such Default or Event of Default has been cured before the end of the 30-day period, an Officers’ Certificate specifying such Default or Event of Default and what action the Parent Guarantor is taking or proposes to take with respect thereto.

Section 4.05 Taxes.

The Parent Guarantor shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, all material taxes, assessments and governmental charges levied or imposed upon the Parent Guarantor or any Subsidiary or upon the income, profits or property of the Parent Guarantor or any Subsidiary; provided, however, that the Parent Guarantor shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment or charge the amount, applicability or validity of which is being contested in good faith by appropriate proceedings promptly instituted and diligently conducted; provided that any reserve or other appropriate provision as will be required in conformity with GAAP will have been made therefor.

Section 4.06 Stay, Extension and Usury Laws.

The Company and each of the Guarantors covenant (to the extent that they may lawfully do so) that they shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant that they shall not, by resort to any such law, 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 has been enacted.

Section 4.07 Incurrence of Indebtedness and Issuance of Disqualified Stock.

(a) The Parent Guarantor will not, and will not cause or permit the Company or any Restricted Subsidiary to, create, issue, incur, assume, guarantee or otherwise in any manner become directly or indirectly liable for the payment of or otherwise incur, contingently or otherwise (collectively, “incur”), any Indebtedness (including any Acquired Debt and the issuance of Disqualified Stock or the issuance of Preferred Stock by the Company or a Restricted Subsidiary), unless such Indebtedness is incurred by the Parent Guarantor, the Company or any Guarantor and, in each case, after giving pro forma effect to such incurrence and the receipt and application of the proceeds therefrom, the Parent Guarantor’s Consolidated Fixed Charge Coverage Ratio for the most recent four full fiscal quarters for which financial statements are available immediately preceding the incurrence of such Indebtedness taken as one period would be equal to or greater than 2.25 to 1.0.

(b) Notwithstanding the foregoing, the Parent Guarantor, the Company and, to the extent specifically set forth below, the Restricted Subsidiaries may incur each and all of the following (collectively, the “Permitted Debt”):

(1) Indebtedness of the Company or any Guarantor (whether as borrowers or guarantors) under one or more Credit Facilities in an aggregate principal amount at any one time outstanding not to exceed the greater of (x) $250.0 million and (y) the sum of $100.0 million and 30% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such Indebtedness;

(2) Indebtedness of the Company or any Guarantor pursuant to the Notes (including any Exchange Notes but excluding any Additional Notes and Exchanges Notes issued in exchange therefor) and any Guarantee of the Notes;

(3) Indebtedness of the Company or any Guarantor outstanding on the Issue Date, and not otherwise referred to in this definition of “Permitted Debt”;

(4) intercompany Indebtedness between or among the Parent Guarantor, the Company and any Restricted Subsidiary; provided, however, that:

(a) if the Company or any Guarantor is the obligor on such Indebtedness and such Indebtedness is owed to a Restricted Subsidiary other than a Guarantor, such Indebtedness shall be either (x) expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes, in the case of the Company, or the Guarantee, in the case of a Guarantor, or (y) Capital Stock; and

(b) any subsequent issuance or transfer of Capital Stock that results in any such Indebtedness being held by a Person other than the Parent Guarantor, the Company or a Restricted Subsidiary (other than pursuant to a Credit Facility) and any sale or other transfer of any such Indebtedness to a Person that is not either the Parent Guarantor, the Company or a Restricted Subsidiary, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Parent Guarantor, the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (4);

(5) guarantees by the Company or any Guarantor of any Indebtedness of the Parent Guarantor, the Company or any Restricted Subsidiary that is permitted to be incurred under this Indenture;

(6) Indebtedness of the Parent Guarantor, the Company or any Restricted Subsidiary represented by Capital Lease Obligations (whether or not incurred pursuant to sale and leaseback transactions) or Purchase Money Obligations or other Indebtedness incurred or assumed in connection with the acquisition, construction, improvement or development of real or personal, movable or immovable, property, in each case incurred for the purpose of financing or Refinancing all or any part of the purchase price or cost of acquisition, construction, improvement or development of property used in the business of the Parent Guarantor, the Company or any Restricted Subsidiary (together with

improvements, additions, accessions and contractual rights relating primarily thereto), in an aggregate principal amount outstanding at any time pursuant to this clause (6) not to exceed the greater of (x) $25.0 million and (y) 2.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such Indebtedness;

(7) Indebtedness of the Parent Guarantor, the Company or any Restricted Subsidiary in connection with (a) one or more standby letters of credit issued by the Parent Guarantor, the Company or a Restricted Subsidiary in the ordinary course of business and (b) other self-insurance obligations, letters of credit, surety, bid, performance, appeal or similar bonds, bankers’ acceptances, completion guarantees or similar instruments and any guarantees or letters of credit functioning as or supporting any of the foregoing instruments; provided that, in each case contemplated by this clause (7), upon the drawing of such letters of credit or other instrument, such obligations are reimbursed within 30 days following such drawing; provided further that with respect to clauses (a) and (b), such Indebtedness is not in connection with the borrowing of money;

(8) Indebtedness of the Parent Guarantor, the Company or any Guarantor; provided that sufficient net proceeds thereof are promptly deposited to effect a Legal Defeasance or Covenant Defeasance with respect to all of the Notes pursuant to Article Eight or a Satisfaction and Discharge with respect to all of the Notes pursuant to Article Eleven;

(9) Permitted Refinancing Indebtedness of the Company or any Guarantor issued to Refinance any Indebtedness, including any Disqualified Stock, incurred pursuant to Section 4.07(a) and clauses (2), (3), (11) and this clause (9) of this paragraph (b) of this Section 4.07;

(12) Cash Management Obligations of the Company or any Guarantor in an aggregate amount not to exceed $7.5 million outstanding at any one time;

(13) Preferred Stock (other than Disqualified Stock) of the Parent Guarantor, the Company or any Restricted Subsidiary; and

(14) Indebtedness of the Parent Guarantor, the Company or any Restricted Subsidiary in addition to that described in clauses (1) through (13) above, so long as the aggregate principal amount of all such Indebtedness incurred pursuant to this clause (14) outstanding at any one time in the aggregate shall not exceed the greater of (x) $35.0 million and (y) 2.5% of Adjusted Consolidated Net Tangible Assets determined as of the date of the incurrence of such Indebtedness.

(c) For purposes of determining compliance with this Section 4.07, in the event that an item of Indebtedness meets the criteria of more than one of the categories of

“Permitted Debt” or is permitted to be incurred pursuant to paragraph (a) of this Section 4.07, the Company in its sole discretion may classify or reclassify (or later classify or reclassify) in whole or in part such item of Indebtedness in any manner (including by dividing and classifying such item of Indebtedness in more than one type of Indebtedness permitted under this Section 4.07) that complies with this Section 4.07; provided that Indebtedness under the Senior Credit Agreement, if any, which is in existence on the Issue Date shall be considered incurred under clause (1) of paragraph (b) of this Section 4.07, subject to any subsequent classification or reclassification or division permitted pursuant to this paragraph (c).

(d) Indebtedness permitted by this Section 4.07 need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.07 permitting such Indebtedness.

(e) Accrual of interest, accretion or amortization of original issue discount or accretion of principal as to a security issued at a discount and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the accretion or payment of dividends on any Disqualified Stock or Preferred Stock in the form of additional shares of the same class of Disqualified Stock or Preferred Stock, the obligation to pay a premium in respect of Indebtedness arising in connection with the issuance of a notice of redemption or making of a mandatory offer to purchase such Indebtedness, and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of SFAS 133), each will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.07; provided, in each such case, that the amount thereof as accrued shall be included as required in the calculation of the Consolidated Fixed Charge Coverage Ratio of the Parent Guarantor.

(f) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar- equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar- denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Parent Guarantor, the Company and the Restricted Subsidiaries may incur pursuant to this Section 4.07 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rates of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(g) For purposes of determining any particular amount of Indebtedness under this Section 4.07, (i) guarantees of, or obligations in respect of letters of credit relating to, Indebtedness otherwise included in the determination of such amount shall not also be included and (ii) if obligations in respect of letters of credit are incurred pursuant to a Credit Facility and are being treated as incurred pursuant to clause (1) of the definition of “Permitted Debt” and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included. If Indebtedness is secured by a letter of credit that serves only to secure such Indebtedness, then the total amount deemed incurred shall be equal to the greater of (x) the principal of such Indebtedness and (y) the amount that may be drawn under such letter of credit.

(h) For purposes of this Indenture, no Indebtedness will be deemed to be subordinate or junior in right of payment to other Indebtedness solely by virtue of not having the benefit of a Lien on assets, or guarantee of a Person, that benefits the other Indebtedness or having the benefit of such a Lien or guarantee ranking subordinate or junior to a Lien or guarantee benefiting the other Indebtedness.

Section 4.08 Restricted Payments.

(a) The Parent Guarantor will not, and will not cause or permit the Company or any Restricted Subsidiary to, directly or indirectly:

(i) pay any dividend on, or make any distribution to holders of, any shares of the Parent Guarantor’s Capital Stock (other than dividends or distributions payable solely to the Parent Guarantor, the Company or a Restricted Subsidiary or in shares of the Parent Guarantor’s Qualified Capital Stock or in options, warrants or other rights to acquire shares of such Qualified Capital Stock);

(ii) purchase, redeem, defease or otherwise acquire or retire for value, directly or indirectly, the Parent Guarantor’s Capital Stock or options, warrants or other rights to acquire such Capital Stock other than through the exchange therefor solely of Qualified Capital Stock of the Parent Guarantor and other than any acquisition or retirement for value from, or payment to, the Parent Guarantor, the Company or any Restricted Subsidiary;

(iii) make any principal payment on, or repurchase, redeem, defease, retire or otherwise acquire for value, prior to any scheduled principal payment, sinking fund payment or maturity, any Subordinated Indebtedness, other than (x) Subordinated Indebtedness permitted under clause (4) of Section 4.07(b) or (y) Subordinated Indebtedness acquired for value in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of acquisition for value;

(iv) pay any dividend or distribution on any Capital Stock of the Company or any Restricted Subsidiary to any Person (other than (a) to the Parent Guarantor, the Company or any Restricted Subsidiary or any Guarantor or (b) dividends or distributions made by the Company or a Restricted Subsidiary on a pro rata basis to all stockholders of the Company or such Restricted Subsidiary); or

(v) make any Investment in any Person (other than any Permitted Investments);

(any of the foregoing actions described in clauses (i) through (v) above, other than any such action that is a Permitted Payment (as defined below), collectively, “Restricted Payments”) (the amount of any such Restricted Payment, if other than cash, shall be the Fair Market Value of the assets proposed to be transferred) as determined by the Board of Directors of the Parent Guarantor, whose determination shall be conclusive and evidenced by a Board Resolution, unless

(1) immediately after giving effect to such proposed Restricted Payment on a pro forma basis, no Default or Event of Default shall have occurred and be continuing;

(2) immediately after giving effect to such Restricted Payment on a pro forma basis, the Parent Guarantor or the Company could incur $1.00 of additional Indebtedness (other than Permitted Debt) under Section 4.07(a); and

(B) the aggregate Net Cash Proceeds, or the Fair Market Value of property (including any property received in any asset or other acquisition) other than cash, received after the Issue Date by the Parent Guarantor either (1) as capital contributions in the form of common equity or other Qualified Capital Stock to the Parent Guarantor or (2) from the issuance or sale (other than to the Company or any Restricted Subsidiary) of Qualified Capital Stock of the Parent Guarantor or any options, warrants or rights to purchase such Qualified Capital Stock of the Parent Guarantor (except, in each case, to the extent such proceeds are used to purchase, redeem or otherwise retire Capital Stock or Subordinated Indebtedness as set forth below in clause (2) or (3) of paragraph (b) of this Section 4.08) (and excluding the Net Cash Proceeds from the issuance of Qualified Capital Stock financed, directly or indirectly, using funds borrowed from the Parent Guarantor, the Company or any Restricted Subsidiary until and to the extent such borrowing is repaid);

(C) the aggregate Net Cash Proceeds, or the Fair Market Value of property other than cash, received after the Issue Date by the Parent Guarantor (other than from the Company or any Restricted Subsidiary) upon the exercise of any options, warrants or rights to purchase Qualified Capital Stock of the Parent Guarantor (and excluding the Net Cash Proceeds from the exercise of any options, warrants or rights to purchase Qualified

Capital Stock financed, directly or indirectly, using funds borrowed from the Parent Guarantor, the Company or any Restricted Subsidiary until and to the extent such borrowing is repaid);

(D) the aggregate Net Cash Proceeds, or the Fair Market Value of property other than cash, received after the Issue Date by the Parent Guarantor from the conversion or exchange, if any, of debt securities or Disqualified Stock or other Indebtedness of the Parent Guarantor, the Company or the Restricted Subsidiaries into or for Qualified Capital Stock of the Parent Guarantor plus, to the extent such debt securities or Disqualified Stock were issued after the Issue Date, the aggregate of Net Cash Proceeds, or the Fair Market Value of property other than cash, received from their original issuance (and excluding the Net Cash Proceeds from the conversion or exchange of debt securities or Disqualified Stock financed, directly or indirectly, using funds borrowed from the Parent Guarantor, the Company or any Restricted Subsidiary until and to the extent such borrowing is repaid);

(b) in the case of the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary (as long as the designation of such Subsidiary as an Unrestricted Subsidiary was deemed a Restricted Payment), the Fair Market Value of the Parent Guarantor’s interest in such Subsidiary at the time of such redesignation; and

(F) any amount which previously qualified as a Restricted Payment on account of any guarantee entered into by the Parent Guarantor, the Company or any Restricted Subsidiary; provided that such guarantee has not been called upon and the obligation arising under such guarantee no longer exists.

(b) Notwithstanding the foregoing, and in the case of clauses (2) through (9) and (11) through (14) below, so long as no Default or Event of Default is continuing or would arise therefrom, the foregoing provisions shall not prohibit the following actions (each of clauses (1) through (14), together with the transactions expressly excluded from clauses (i), (ii), (iii) and (iv) of paragraph (a) of this Section 4.08, being referred to as a “Permitted Payment”):

(a) in the case of a Change of Control, the Company has first complied with and fully satisfied its obligations under Section 4.17; or

(b) in the case of an Asset Sale, the Company has complied with and fully satisfied its obligations in accordance with Section 4.11;

The amount of all Restricted Payments and other such transactions (other than cash) shall be the Fair Market Value on the date of the transfer, incurrence or issuance of such non-cash Restricted Payment or other such transaction.

(d) A contribution or sale will be deemed to be “substantially concurrent” if the related purchase, repurchase, redemption, defeasance, satisfaction and discharge, retirement or other acquisition for value or payment of principal occurs within 90 days before or after such contribution or sale.

Section 4.09 Transactions with Affiliates.

(a) The Parent Guarantor will not, and will not cause or permit the Company or any Restricted Subsidiary to, directly or indirectly, enter into any Transaction (including the sale, purchase, exchange or lease of assets, property or services) with or for the benefit of any Affiliate of the Parent Guarantor (other than the Parent Guarantor, the Company or a Restricted

Subsidiary) involving aggregate consideration in excess of $2.0 million, unless such Transaction is entered into in good faith and

(1) such Transaction is on terms that are not materially less favorable to the Parent Guarantor, the Company or such Restricted Subsidiary, as the case may be, than those that would be available in a comparable Transaction in arm’s-length dealings with a party that is not an Affiliate of the Company,

(2) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture; provided that in the reasonable determination of the Board of Directors of the Parent Guarantor or the senior management of the Parent Guarantor, such transactions are on terms not materially less favorable to the Parent Guarantor, the Company or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Parent Guarantor,

(3) the payment of reasonable and customary compensation and fees to officers or directors of the Parent Guarantor, the Company or any Restricted Subsidiary who are not employees of the Parent Guarantor or any Affiliate of the Parent Guarantor,

pursuant to clauses (1)(iv) and (15) of the definition thereof (to the extent involving, prior to the making of such Permitted Investment, any Person other than the Parent Guarantor or a Subsidiary of the Parent Guarantor)),

(6) any Transaction undertaken pursuant to (a) any contracts or agreements in existence on the Issue Date (as in effect on the Issue Date) (b) any amendment or replacement of any such agreements or (c) any agreements entered into hereafter that are similar to any such agreements, so long as, in the case of clause (b) or (c), the terms of any such amendment or replacement agreement or future agreement are, on the whole, no less advantageous to the Parent Guarantor or the Company or no less favorable to the Holders in any material respect than the agreement so amended or replaced or the similar agreement referred to in the preceding clause (a) or (b), respectively,

(7) in the case of (1) contracts for (A) drilling or other oil-field services or supplies, (B) the sale, storage, gathering or transport of Hydrocarbons or (C) the lease or rental of office or storage space or (2) other operation-type contracts, any such contracts that are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Parent Guarantor, the Company or any Restricted Subsidiary and third parties or, if none of the Parent Guarantor, the Company nor any Restricted Subsidiary has entered into a similar contract with a third party, on terms no less favorable than those available from third parties on an arm’s-length basis, as determined (i) in the case of contracts involving aggregate value of $50.0 million or less, by the Board of Directors of the Parent Guarantor or the senior management of the Parent Guarantor or (ii) in the case of contracts involving aggregate value in excess of $50.0 million, by the Disinterested Directors of the Board of Directors of the Parent Guarantor,

(9) any sale or other issuance of Qualified Capital Stock of the Parent Guarantor to, or receipt of a capital contribution from, an Affiliate (or a Person that becomes an Affiliate) of the Parent Guarantor,

(10) any Transaction between the Parent Guarantor, the Company or any Restricted Subsidiary on the one hand and any Person deemed to be an Affiliate solely because one or more directors of such Person is also a director of the Parent Guarantor, the Company or a Restricted Subsidiary, on the other hand; provided that such director or directors abstain from voting as a director of the Parent Guarantor, the Company or the Restricted Subsidiary, as applicable, in connection with the approval of the Transaction,

Section 4.10 Liens.

(a) The Parent Guarantor will not, and will not cause or permit the Company or any Restricted Subsidiary to, directly or indirectly, create or incur, in order to secure any Indebtedness, any Lien of any kind, other than Permitted Liens, upon any property or assets (including any intercompany notes) of the Parent Guarantor, the Company or any Restricted Subsidiary owned on the Issue Date or acquired after the Issue Date, or assign or convey, in order to secure any Indebtedness, any right to receive any income or profits therefrom, other than Permitted Liens, unless the Notes (or a Guarantee in the case of Liens of a Guarantor) are directly secured equally and ratably with (or, in the case of Subordinated Indebtedness, prior or senior thereto, with the same relative priority as the Notes shall have with respect to such Subordinated Indebtedness) the Indebtedness for so long as such Indebtedness is secured by such Lien.

(b) Notwithstanding the foregoing, any Lien securing the Notes or a Guarantee granted pursuant to Section 4.10(a) shall be automatically and unconditionally released and discharged upon: (i) the release of all other Liens that resulted in the grant of such Lien to secure the Notes or Guarantees pursuant to Section 4.10(a), (ii) any sale, exchange or transfer to any Person not an Affiliate of the Company of the property or assets secured by such Lien, (iii) any sale, exchange or transfer to any Person not an Affiliate of the Company of all of the Capital Stock held by the Parent Guarantor, the Company or any Restricted Subsidiary in, or all or substantially all the assets of, any Restricted Subsidiary creating such Lien, or (iv) if such Lien secures a Guarantee, the release of such Guarantee in accordance with this Indenture.

Section 4.11 Asset Sales.

(a) The Parent Guarantor will not, and will not permit the Company or any Restricted Subsidiary to, consummate any Asset Sale unless (i) the Parent Guarantor, the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets and property subject to such Asset Sale (such Fair Market Value to be determined on the date of contractually agreeing to effect such Asset Sale) and (ii) (A) at least 75% of the consideration paid to the Parent Guarantor, the Company or such Restricted Subsidiary from such Asset Sale and all other Asset Sales since the Issue Date, on a cumulative basis, is in the form of cash, Cash Equivalents,

Liquid Securities, Exchanged Properties (including pursuant to Asset Swaps) or the assumption by acquiring Person of Indebtedness or other liabilities of the Parent Guarantor, the Company or a Restricted Subsidiary (other than liabilities of the Parent Guarantor, the Company or a Restricted Subsidiary that are by their terms subordinated to the Notes) as a result of which the Parent Guarantor, the Company and the remaining Restricted Subsidiaries are no longer liable for such liabilities (or in lieu of such absence of liability, the acquiring Person or its parent company agrees to indemnify and hold the Parent Guarantor, the Company or such Restricted Subsidiary harmless from and against any loss, liability or cost in respect of such assumed liabilities accompanied by the posting of a letter of credit (issued by a commercial bank that has an Investment Grade Rating) in favor of the Parent Guarantor, the Company or such Restricted Subsidiary for the full amount of such liabilities and for so long as such liabilities remain outstanding unless such indemnifying party (or its long term debt securities) shall have an Investment Grade Rating (with no indication of a negative outlook or credit watch with negative implications, in any case, that contemplates such indemnifying party (or its long term debt securities) failing to have an Investment Grade Rating) at the time the indemnity is entered into) (“Permitted Consideration”) or (B) the Fair Market Value of all forms of such consideration other than Permitted Consideration since the Issue Date does not exceed in the aggregate 5% of the Adjusted Consolidated Net Tangible Assets of the Parent Guarantor determined at the time such Asset Sale is made.

(b) During the 365 days after the receipt by the Parent Guarantor, the Company or a Restricted Subsidiary of Net Available Cash from an Asset Sale, such Net Available Cash may be applied by the Parent Guarantor, the Company or such Restricted Subsidiary, to the extent the Parent Guarantor, the Company or such Restricted Subsidiary elects (or is required by the terms of any Pari Passu Indebtedness of the Parent Guarantor, the Company or a Restricted Subsidiary), to:

(1) repay (or cash-collateralize) Indebtedness of the Parent Guarantor, the Company or any Restricted Subsidiary under any Credit Facility (excluding (i) any Subordinated Indebtedness and (ii) any Indebtedness owed to the Company or an Affiliate of the Company);

(2) reinvest in Additional Assets (including by means of an Investment in Additional Assets by the Parent Guarantor, the Company or a Restricted Subsidiary with Net Available Cash received by the Parent Guarantor, the Company or another Restricted Subsidiary) or make capital expenditures in the Oil and Gas Business;

(3) purchase Notes;

(4) purchase or repay on a permanent basis other Indebtedness (excluding (i) any Subordinated Indebtedness and (ii) any Notes or other Indebtedness owed to the Company or an Affiliate of the Company); provided that the Company shall equally and ratably redeem or purchase Notes as described under Section 3.07, through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for a Prepayment Offer) to all Holders to purchase the Notes at 100% of the principal amount

thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid; or

(5) make any combination of payment, repayment, investment or reinvestment permitted by the foregoing clauses (1) through (4).

The requirement of clause (b)(2) above shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or investment referred to therein is entered into by the Parent Guarantor, the Company or any Restricted Subsidiary within the time period specified in this Section 4.11(b) and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

Pending the final application of any such Net Available Cash, the Company may temporarily reduce Indebtedness under any Credit Facility or otherwise expend or invest such Net Available Cash in any manner that is not prohibited by this Indenture

(c) Any Net Available Cash from an Asset Sale not applied in accordance with Section 4.11(b) above within 365 days from the date of such Asset Sale shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, the Company will be required to make an offer to purchase Notes having an aggregate principal amount equal to the aggregate amount of Excess Proceeds (the “Prepayment Offer”) at a purchase price (the “Prepayment Offer Price”) equal to 100% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the Asset Sale Purchase Date (as defined in Section 4.11(d)) (subject to the rights of Holders of record on relevant record dates to receive interest due on an interest payment date) in accordance with the procedures (including prorating in the event of over subscription) set forth in this Indenture, but, if the terms of any Pari Passu Indebtedness require that a Pari Passu Offer be made contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be prorated between the Prepayment Offer and such Pari Passu Offer in accordance with the aggregate outstanding principal amounts of the Notes and such Pari Passu Indebtedness (based on principal amounts of Notes and Pari Passu Indebtedness (or, in the case of Pari Passu Indebtedness issued with significant original issue discount, based on the accreted value thereof) tendered), and the aggregate principal amount of Notes to be purchased pursuant to the Prepayment Offer shall be reduced accordingly. If the aggregate principal amount of Notes tendered by Holders thereof exceeds the amount of Excess Proceeds available for purchase of Notes, then such amount of Excess Proceeds will be allocated among the Notes tendered and the Trustee will select the Notes to be purchased in accordance with this Indenture on a pro rata basis (or, in the case of Global Notes, on as nearly a pro rata basis as is practicable, subject to the procedures of DTC or any other Depositary), by lot or in accordance with any other method the Trustee considers fair and reasonable and in minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. To the extent that any portion of the amount of Excess Proceeds remains after compliance with this Section 4.11(c) and provided that all Holders of Notes have been given the opportunity to tender their Notes for purchase as described in Section 4.11(d) in accordance with this Indenture, the Parent Guarantor, the Company or the Restricted Subsidiaries may use such remaining amount for purposes permitted by this Indenture and the amount of Excess Proceeds will be reset to zero. The Company may satisfy the foregoing obligation with respect to any Excess Proceeds by making a

Prepayment Offer prior to the expiration of the relevant 365 day period or with respect to Excess Proceeds of $25.0 million or less.

(d) Within 30 days after the 365th day following the date of an Asset Sale, the Company shall, if it is obligated to make a Prepayment Offer pursuant to Section 4.11(c), send a written Prepayment Offer notice, by first-class mail or otherwise in accordance with the procedures of DTC, to the Holders of the Notes (the “Prepayment Offer Notice”), with a copy to the Trustee, accompanied by such information regarding the Company and its Subsidiaries as the Company believes will enable such Holders of the Notes to make an informed decision with respect to the Prepayment Offer. The Prepayment Offer Notice will state, among other things:

(1) that the Company is offering to purchase Notes pursuant to the provisions of this Indenture;

(2) that any Note (or any portion thereof) accepted for payment (and duly paid on the Asset Sale Purchase Date) pursuant to the Prepayment Offer shall cease to accrue interest on the Asset Sale Purchase Date;

(3) that any Notes (or portions thereof) not properly tendered will continue to accrue interest;

(4) the purchase price and purchase date, which shall be, subject to any contrary requirements of applicable law, no less than 30 days nor more than 60 days after the date the Prepayment Offer Notice is mailed (the “Asset Sale Purchase Date”);

(5) the amount of Excess Proceeds available to purchase Notes;

(6) a description of the procedure which Holders of Notes must follow in order to tender their Notes and the procedures that Holders of Notes must follow in order to withdraw an election to tender their Notes for payment; and

(7) all other instructions and materials necessary to enable Holders to tender Notes pursuant to the Prepayment Offer.

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

(e) The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Prepayment Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.11 by virtue thereof.

(f) Holders electing to have Notes purchased hereunder will be required to surrender such Notes at the address specified in the notice prior to the close of business on the

third Business Day prior to the Asset Sale Purchase Date. Holders will be entitled to withdraw their election to have their Notes purchased pursuant to this Section 4.11 if the Company receives, not later than one Business Day prior to the Asset Sale Purchase Date, a telegram, telex, facsimile transmission or letter specifying, as applicable:

(1) the name of the Holder,

(2) the certificate number of the Note in respect of which such notice of withdrawal is being submitted,

(3) the principal amount of the Note (which shall be $2,000 or whole multiples of $ 1,000 in excess thereof) delivered for purchase by the Holder as to which his election is to be withdrawn,

(4) a statement that such Holder is withdrawing his election to have such principal amount of such Note purchased, and

(5) the principal amount, if any, of such Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original Prepayment Offer Notice and that has been or will be delivered for purchase by the Company.

(g) The Company shall (i) not later than the Asset Sale Purchase Date accept for payment Notes or portions thereof tendered pursuant to the Prepayment Offer, (ii) not later than 12:30 p.m. (New York City time) on the Asset Sale Purchase Date deposit with the Trustee or with a Paying Agent an amount of money in same day funds sufficient to pay the aggregate Prepayment Offer Price, as the case may be, of all the Notes or portions thereof which are to be purchased on that date and (iii) not later than 12:30 p.m. (New York City time) on the Asset Sale Purchase Date, as the case may be, deliver to the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted for payment by the Company. The Company shall publicly announce the results of the Prepayment Offer, as the case may be, on or as soon as practicable after the Asset Sale Purchase Date.

(h) Upon receipt by the Company of the proper tender of any Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c), the Holder of the Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c) in respect of which such proper tender was made and which has so been accepted for purchase shall (unless the tender of such Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c) is properly withdrawn at least one Business Day prior to the Asset Sale Purchase Date) thereafter be entitled to receive solely the Prepayment Offer Price with respect to such Note (or portion thereof) accepted for purchase pursuant to Section 4.11(c). Notes to be purchased shall, on the Asset Sale Purchase Date, become due and payable at the Prepayment Offer Price and from and after such date (unless the Company shall default in the payment of the Prepayment Offer Price) such Notes shall cease to bear interest. Such Prepayment Offer Price shall be paid to such Holder promptly following the later of the Asset Sale Purchase Date and the time of delivery of such Note to the relevant Paying Agent at the office of such Paying Agent by the Holder thereof in the manner required. Upon surrender of any such Note for purchase in accordance with the foregoing provisions, such Note shall be paid by the Company at the Prepayment Offer Price; provided, however, that

installments of interest whose Stated Maturity is on or prior to the Asset Sale Purchase Date shall be payable to the Person in whose name the Notes are registered as such as of the close of business on the relevant record dates according to the terms and the provisions of Section 2.04. If any Note tendered for purchase shall not be so paid upon surrender thereof by deposit of funds with the Trustee or a Paying Agent in accordance with paragraph (g) of this Section 4.11, the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the Asset Sale Purchase Date at the rate borne by such Note. Any Note that is to be purchased only in part shall be surrendered to a Paying Agent at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Registrar or the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, one or more new Notes of any authorized denomination as requested by such Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased. For all purposes of this Section 4.11, unless the context otherwise requires, all provisions relating to the purchase of Notes shall relate, in the case of any Notes purchased or to be purchased only in part, to the portion of the principal amount of such Notes which has been or is to be purchased. The Paying Agent (at the Company’s expense) shall promptly mail or deliver to the Holder thereof any Note or portion thereof not to be so purchased.

Section 4.12 Issuances of Guarantees by Restricted Subsidiaries.

(a) The Parent Guarantor will provide to the Trustee, on or prior to the 30th day after the date that any Restricted Subsidiary (which is not a Guarantor) becomes a guarantor or obligor in respect of any Indebtedness of the Parent Guarantor, the Company or any Restricted Subsidiary in an aggregate principal amount exceeding $5.0 million, a supplemental indenture to this Indenture substantially in the form of Exhibit D hereto, executed by such Restricted Subsidiary, providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary’s obligations under the Notes and this Indenture to the same extent as that set forth in this Indenture, subject to such Restricted Subsidiary ceasing to be a Guarantor when its Guarantee is released in accordance with the terms of this Indenture.

(b) Notwithstanding paragraph (a) of this Section 4.12, (i) no Foreign Subsidiary shall be required to execute any such supplemental indenture unless such Foreign Subsidiary has guaranteed (or is otherwise an obligor of) other Indebtedness (including Indebtedness under a Credit Facility) of the Parent Guarantor, the Company or a Restricted Subsidiary that is not a Foreign Subsidiary in an aggregate principal amount exceeding $5.0 million, and (ii) no Restricted Subsidiary shall be required to execute any such supplemental indenture if the Consolidated Net Worth of such Restricted Subsidiary, together with the Consolidated Net Worth of all other Non-Guarantor Restricted Subsidiaries, as of such date, does not exceed in the aggregate $5.0 million. To the extent the collective Consolidated Net Worth of the Parent Guarantor’s Non-Guarantor Restricted Subsidiaries, as of the date of the creation of, acquisition of or Investment in a Non-Guarantor Restricted Subsidiary, exceeds $5.0 million, the Parent Guarantor shall cause, within 30 days after such date, one or more of such Non-Guarantor Restricted Subsidiaries to similarly execute and deliver to the Trustee a supplemental indenture to this Indenture substantially in the form of Exhibit D hereto providing for a full and

unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary of the Company’s obligations under the Notes and this Indenture to the same extent as that set forth as to the Initial Guarantors in Article Ten, such that the collective Consolidated Net Worth of all remaining Non-Guarantor Restricted Subsidiaries does not exceed $5.0 million.

Section 4.13 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

(a) The Parent Guarantor will not, and will not cause or permit the Company or any Restricted Subsidiary to, directly or indirectly, create or otherwise cause to come into existence or become effective any consensual encumbrance or restriction on the ability of the Company or any Restricted Subsidiary to:

(1) pay dividends or make any other distribution on its Capital Stock to the Parent Guarantor, the Company or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a restriction on the ability to pay dividends or make distributions on Capital Stock),

(2) pay any Indebtedness owed to the Parent Guarantor, the Company or any other Restricted Subsidiary (it being understood that the subordination of Indebtedness owed to the Parent Guarantor, the Company or any Restricted Subsidiary to other Indebtedness owed by the Parent Guarantor, the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to pay such Indebtedness),

(3) make loans or advances to the Parent Guarantor, the Company or any other Restricted Subsidiary (it being understood that the subordination of loans or advances made by the Parent Guarantor, the Company or any Restricted Subsidiary to other Indebtedness incurred by the Parent Guarantor, the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances), or

(4) transfer any of its properties or assets to the Parent Guarantor, the Company or any other Restricted Subsidiary.

(b) However, Section 4.13(a) will not prohibit any encumbrance or restriction created, existing or becoming effective under or by reason of:

(1) any agreement (including the Senior Credit Agreement) in effect on the Issue Date;

(2) any agreement or instrument with respect to a Restricted Subsidiary that is not a Restricted Subsidiary on the Issue Date, in existence at the time such Person becomes a Restricted Subsidiary and not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary; provided that such encumbrances and restrictions are not applicable to, or to the properties or assets of, the Parent Guarantor, the Company or any Restricted Subsidiary other than such Subsidiary which is becoming a Restricted Subsidiary;

(3) any agreement or instrument governing any Acquired Debt or other agreement of any entity merged into or consolidated with, or the assets of which are acquired by,

the Parent Guarantor, the Company or any Restricted Subsidiary, so long as such encumbrance or restriction (A) was not entered into in contemplation of the acquisition, merger or consolidation transaction, and (B) is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets or subsidiaries of the Person, so acquired, so long as the agreement containing such restriction does not violate any other provision of this Indenture;

(4) any applicable law or any requirement of any regulatory body;

(5) customary restrictions and conditions contained in the security documents evidencing any Liens securing obligations or Indebtedness or agreements relating to Capital Lease Obligations (provided that such Liens are otherwise permitted to be incurred under the provisions of Section 4.10 and such restrictions and conditions are not created for the purpose of avoiding the restrictions imposed by this Section 4.13) that limit the right of the debtor or lessee to dispose of the assets subject to such Liens;

(6) provisions restricting subletting or assignment of any lease governing a leasehold interest (including leases governing leasehold interests or farm-in agreements or farm- out agreements relating to leasehold interests in Oil and Gas Properties) of the Parent Guarantor, the Company or any Restricted Subsidiary, or restrictions in licenses (including licenses of intellectual property) relating to the property covered thereby, or other encumbrances or restrictions in agreements or instruments relating to specific assets or property that restrict generally the transfers of such assets or property; provided that such encumbrances or restrictions do not materially impact the ability of the Company to permit payments on the Notes when due as required by the terms of this Indenture;

(7) agreements with respect to asset sales, including the sale or other disposition of all or substantially all the Capital Stock of a Restricted Subsidiary, permitted to be made under the provisions of Section 4.11 that limit the transfer of such assets or assets of such Restricted Subsidiary (or distribution on such Capital Stock) pending the closing of such sale;

(8) shareholders’, partnership, joint venture and similar agreements entered into in the ordinary course of business; provided that such encumbrances or restrictions do not apply to any Restricted Subsidiaries other than the applicable company, partnership, joint venture or other entity;

(9) cash, Cash Equivalents or other deposits, or net worth requirements or similar requirements, imposed by suppliers, landlords or customers under contracts entered into in the ordinary course of business;

(10) any Credit Facility or agreement governing Indebtedness of the Parent Guarantor, the Company or any Restricted Subsidiary permitted to be incurred under the provisions of Section 4.07; provided that such encumbrances or restrictions are not materially more restrictive, taken as a whole, as determined by the Company in good faith, than those contained in the Senior Credit Agreement or in this Indenture as in effect on the Issue Date;

(11) restrictions of the nature described in clause (4) of Section 4.13(a) by reason of customary non-assignment provisions in Hydrocarbon purchase or sale or exchange contracts, agreements, licenses and leases entered into in the ordinary course of business;

(a) The Board of Directors of the Parent Guarantor may designate after the Issue Date any of its Subsidiaries (other than the Company) as an Unrestricted Subsidiary under this Indenture (a “Designation”) only if:

(1) no Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such Designation;

(2) (x) the Parent Guarantor would be permitted to make an Investment at the time of Designation (assuming the effectiveness of such Designation) pursuant to paragraph (a) of Section 4.08 or as a Permitted Payment or Permitted Investment in an amount (the “Designation Amount”) equal to the greater of (1) the net book value of the Parent Guarantor’s interest in such Subsidiary calculated in accordance with GAAP and (2) the Fair Market Value of the Parent Guarantor’s interest in such Subsidiary as determined in good faith by the Parent Guarantor’s Board of Directors, or (y) the Designation Amount is less than $1,000;

(b) In the event of any such Designation, the Parent Guarantor shall be deemed, for all purposes of this Indenture, to have made an Investment equal to the Designation

Amount that, as designated by the Parent Guarantor, constitutes a Restricted Payment pursuant to paragraph (a) of Section 4.08 or a Permitted Payment or Permitted Investment.

(c) The Parent Guarantor shall not and shall not cause or permit the Company or any Restricted Subsidiary to at any time:

(2) all Indebtedness of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if incurred at such time, have been permitted to be incurred for all purposes of this Indenture; and

(3) unless such redesignated Subsidiary shall not have any Indebtedness outstanding (other than Indebtedness that would be Permitted Debt), immediately after giving effect to such proposed Revocation, and after giving pro forma effect to the incurrence of any such Indebtedness of such redesignated Subsidiary as if such Indebtedness was incurred on the date of the Revocation, the Parent Guarantor or the Company could incur $1.00 of additional Indebtedness (other than Permitted Debt) pursuant to Section 4.07.

(f) All Designations and Revocations shall be evidenced by a Board Resolution of the Board of Directors of the Parent Guarantor delivered to the Trustee certifying compliance with the provisions of this Section 4.15.

None of the Parent Guarantor, the Company nor any Restricted Subsidiary shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or is paid to all Holders of Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 4.17 Offer to Repurchase upon a Change of Control.

(a) If a Change of Control occurs, each Holder will have the right to require that the Company purchase all or any part (in amounts of $2,000 or whole multiples of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Company will offer to purchase all of the Notes, at a purchase price (the “Change of Control Purchase Price”) in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Purchase Date”) subject to the rights of Holders of record on relevant record dates to receive interest due on an interest payment date. Any Change of Control Offer that is made prior to the occurrence of a Change of Control may at the Company’s discretion be subject to one or more conditions precedent, including the occurrence of a Change of Control.

(b) Within 30 days after any Change of Control or, at the Company’s option, prior to such Change of Control but after it is publicly announced, the Company shall notify the Trustee and give written notice of the Change of Control to each Holder, by first-class mail, postage prepaid, at his address appearing in the Security Register or otherwise in accordance with the procedures of DTC. The notice (the “Change of Control Purchase Notice)” shall state, among other things:

(i) that a Change of Control has occurred or will occur, the date of such event and the circumstances and relevant facts regarding such Change of Control;

(ii) that any Notes (or any portion thereof) accepted for payment (and duly paid on the Change of Control Purchase Date) pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Purchase Date;

(iii) that any Notes (or any portion thereof) not properly tendered will continue to accrue interest;

(iv) the Change of Control Purchase Price and the Change of Control Purchase Date, which shall be, subject to any contrary requirements of applicable law, no less than 30 days nor more than 60 days after the date the notice is mailed; provided that the Change of Control Purchase Date may not occur prior to the Change of Control;

(v) a description of the procedures that Holders of Notes are required to follow in order to tender their Notes and the procedures that Holders of Notes are required to follow in order to withdraw an election to tender their Notes for payment; and

(vi) all other instructions and materials necessary to enable Holders to tender Notes pursuant to the Change of Control Offer.

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

(c) Upon receipt by the Company of the proper tender of Notes, the Holder of the Note in respect of which such proper tender was made shall (unless the tender of such Note is properly withdrawn at least one Business Day prior to the Change of Control Purchase Date) thereafter be entitled to receive solely the Change of Control Purchase Price with respect to such Notes. Notes to be purchased shall, on the Change of Control Purchase Date, become due and payable at the Change of Control Purchase Price, and from and after such date (unless the Company shall default in the payment of the Change of Control Purchase Price) such Notes shall cease to bear interest. Such Change of Control Purchase Price shall be paid to such Holder promptly following the later of the Change of Control Purchase Date and the time of delivery of such Note to the relevant Paying Agent at the office of such Paying Agent by the Holder thereof in the manner required. Upon surrender of any such Note for purchase in accordance with the foregoing provisions, such Note shall be paid by the Company at the Change of Control Purchase Price; provided, however, that installments of interest whose Stated Maturity is on or prior to the Change of Control Purchase Date shall be payable to the Holders of such Notes, registered as such as of the close of business on the relevant record dates according to the terms and the provisions of Section 2.03. If any Note tendered for purchase in accordance with the provisions of this Section 4.17 shall not be so paid upon surrender thereof, the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the Change of Control Purchase Date at the rate borne by such Note. Holders electing to have Notes purchased will be required to surrender such Notes to the Paying Agent at the address specified in the Change of Control Purchase Notice prior to the close of business on the third Business Day prior to the Change of Control Purchase Date. Any Note that is to be purchased only in part shall be surrendered to a Paying Agent at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Registrar or the Trustee, as the case may be, duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, one or more new Notes of any authorized denomination as requested by such Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased. For all purposes of this Section 4.17, unless the context otherwise requires, all provisions relating to the purchase of Notes shall relate, in the case of any Notes purchased or to be purchased only in part, to the portion of the principal amount of such Notes which has been or is to be purchased. The Paying Agent (at the Company’s expense) shall promptly mail or deliver to the Holder thereof any Note or portion thereof not to be so purchased.

(d) The Company shall (i) not later than the Change of Control Purchase Date, accept for payment Notes or portions thereof tendered pursuant to the Change of Control Offer, (ii) not later than 12:30 p.m. (New York City time) on the Change of Control Purchase Date, deposit with the Trustee or with a Paying Agent an amount of money in same day funds sufficient to pay the aggregate Change of Control Purchase Price of all the Notes or portions thereof that are to be purchased on that date and (iii) not later than 12:30 p.m. (New York City time) on the Change of Control Purchase Date, deliver to the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted for payment by the Company. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date.

(e) A tender made in response to a Change of Control Purchase Notice may be withdrawn if the Company receives, not later than one Business Day prior to the Change of Control Purchase Date, a telegram, telex, facsimile transmission or letter, specifying, as applicable:

(1) the name of the Holder;

(2) the certificate number of the Note in respect of which such notice of withdrawal is being submitted;

(3) the principal amount of the Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) delivered for purchase by the Holder as to which such notice of withdrawal is being submitted;

(4) a statement that such Holder is withdrawing his election to have such principal amount of such Note purchased; and

(5) the principal amount, if any, of such Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original Change of Control Purchase Notice and that has been or will be delivered for purchase by the Company.

(f) The Company shall comply, to the extent applicable, with the requirements of Rule 14e-l under the Exchange Act, and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of the Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Change of Control Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.17 by virtue thereof.

(g) Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer (1) upon a Change of Control, if the Parent Guarantor or 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 Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (2) if notice of redemption for 100% of the aggregate principal amount of the

100

outstanding Notes has been given pursuant to this Indenture as described in Section 3.07, unless and until there is a default in payment of the applicable redemption price.

(h) In the event that upon consummation of a Change of Control Offer less than 10% of the aggregate principal amount of the Notes (including Additional Notes) that were originally issued are hold by Holders other than the Company or Affiliates thereof, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to 101% of the aggregate principal amount of the Notes redeemed plus accrued and unpaid interest, if any, thereon to the date of redemption, subject to the right of the Holders of record on relevant record dates to receive interest due on an interest payment date.

Section 4.18 Corporate Existence.

Subject to Article Five, the Parent Guarantor shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory), licenses and franchises; provided, however, that the Parent Guarantor shall not be required to preserve any such right, license or franchise if it shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Parent Guarantor.

Section 4.19 Covenant Suspension.

(a) If at any time (1) the Notes are rated at least Baa3 by Xxxxx’x and at least BBB- by S&P (or, if either such entity ceases to rate the Notes for reasons outside of the control of the Parent Guarantor, at least the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3- l(c)(2)(vi)(F) under the Exchange Act selected by the Parent Guarantor as a replacement agency); and (2) at such time no Event of Default shall have occurred and is continuing then, beginning on that day and on each day thereafter (subject to the provisions of Section 4.19(c)), the following covenants (the “Suspended Covenants”) will be suspended and the Parent Guarantor, the Company and the Restricted Subsidiaries shall not be subject to (and shall not be required to comply with) the Suspended Covenants:

(i) Section 4.11;

(ii) Section 4.08;

(iii) Section 4.07;

(iv) Section 4.13;

(v) clauses (1) and (3) of Section 4.14;

(vi) clause (5) of Section 5.01(a);

(vii) Section 4.09;

101

(viii) Section 4.15; and

(ix) Section 4.12.

(b) During any period that the foregoing covenants have been suspended (each such period, a “Suspension Period”), the Parent Guarantor’s Board of Directors may not designate any of its Restricted Subsidiaries as Unrestricted Subsidiaries pursuant Section 4.15.

(c) Notwithstanding Sections 4.19(a) and (b), if the rating assigned by either such Rating Agency should subsequently decline to below Baa3 or BBB-, respectively, the Suspended Covenants will be reinstituted on and as of the date of such rating decline (such date, a “Reversion Date”) and on the Reversion Date and each date thereafter (subject to the provisions of Section 4.19(a)) the Parent Guarantor, the Company and the Restricted Subsidiaries shall be subject to (and shall be required to comply with) the Suspended Covenants.

(d) For purposes of calculating the amount available to be made as Restricted Payments under Section 4.08(a)(3), calculations under that clause will be made with reference to the date of the Restricted Payment, as set forth in that clause. Accordingly (x) Restricted Payments made during the Suspension Period that would not otherwise be permitted pursuant to any of clauses (b)(1) through (b)(14) of Section 4.08 will reduce the amount available to be made as Restricted Payments under Section 4.08(a)(3); provided, however, that the amount available to be made as a Restricted Payment shall not be reduced to below zero solely as a result of such Restricted Payments but may be reduced to below zero as a result of negative cumulative Consolidated Net Income during the Suspension Period for purposes of Section 4.08(a)(3)(A) and (y) the items specified in clauses (a)(3)(A) through (F) of Section 4.08 that occur during the Suspension Period will increase the amount available to be made as Restricted Payments under clause (a)(3) of Section 4.08. For purposes of Section 4.11, on each Reversion Date, the unutilized Excess Proceeds will be reset to zero. No Default or Event of Default will be deemed to have occurred or exist on the Reversion Date (or thereafter) under any Suspended Covenant, solely as a result of, or as a result of the continued existence on or after the Reversion Date of facts and circumstances arising from, any actions taken by the Parent Guarantor, the Company or any Restricted Subsidiaries thereof, or events occurring, or performance on or after the Reversion Date of any obligations arising from transactions which occurred, during the Suspension Period.

Section 6.02 Acceleration.

(a) If an Event of Default (other than as specified in Section 6.01 (8) or (9) above with respect to the Parent Guarantor or the Company) shall occur and be continuing with respect to this Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare all unpaid principal of, premium, if any, and accrued interest on all Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders of the Notes) and upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. If an Event of Default specified in Section 6.01(8) or (9) above with respect to the Parent Guarantor or the Company occurs and is continuing, then all the Notes shall ipso facto become due and payable immediately in an amount equal to the principal amount of the Notes, together with accrued and unpaid interest, if any, to the date the Notes become due and payable, without any declaration or other act on the part of the Trustee or any Holder of Notes. Thereupon, the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders of Notes by appropriate judicial proceedings.

(b) After a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of Notes outstanding by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all sums paid or advanced by the Trustee under this Indenture and the reasonable

107

compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, (B) all overdue interest on all Notes then outstanding, (C) the principal of, and premium, if any, on any Notes then outstanding which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Notes, and (D) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate borne by the Notes;

(2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and

(3) all Events of Default, other than the non-payment of principal of, premium, if any, and interest on the Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in this Indenture.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

(c) If an Event of Default specified in 6.01 (5) above shall have occurred and be continuing, such Event of Default and any consequential acceleration shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default shall have been repaid or (ii) if the default relating to such Indebtedness is waived or cured and if such Indebtedness shall have been accelerated, the Holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness.

Section 6.03 Other Remedies.

(a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

(b) 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 of a Note in exercising any right or remedy accruing upon and during the continuance of an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

The Holders of a majority in aggregate principal amount of the Notes outstanding may on behalf of the Holders of all outstanding Notes waive any past Default or Event of Default under this Indenture and its consequences, except a Default or Event of Default (1) in the payment of the principal of, premium, if any, or interest on any Note (which may only be waived with the consent of each Holder of Notes affected) or (2) in respect of a covenant or provision which under Section 9.02 of this Indenture cannot be modified or amended without the consent of the Holder of each Note affected by such modification or amendment. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. Upon any such

108

waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Subject to Section 2.10, Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may subject the Trustee to personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest.

Section 6.06 Limitation on Suits.

(a) A Holder has a right to institute any proceeding with respect to this Indenture, or the Notes or any Guarantees, only if:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default;

(2) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee reasonable indemnity against any loss, liability or expense that might be incurred by it in connection with the request or direction;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

(5) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes have not waived such Event of Default or otherwise given the Trustee a direction inconsistent with the written request.

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, or interest on such Note, on or after the respective due dates expressed in such Note (including in connection with an offer to purchase),

109

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(1) or (2) above occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of overdue principal of, premium, if any, interest remaining unpaid on the Notes and interest on overdue principal and premium, if any, and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company or any Guarantor (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other securities or property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such 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 to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 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.

(a) If the Trustee collects any money or other property pursuant to this Article Six, it shall pay out the money and other property in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

110

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

Third: to the Company or to such party as a court of competent jurisdiction shall direct.

(b) The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

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 a 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 Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07, or a suit by Holders of more than ten percent in principal amount of the then outstanding Notes.

Section 7.05 Notice of Default.

If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after the Trustee gains knowledge of the Default or Event of Default unless such Default or Event of Default shall have been cured or waived before the giving of such notice. Except in the case of a Default or Event of Default in payment of principal of, premium or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

(a) Within 60 days after each May 15 beginning with May 15, 2012, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c).

The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange or any delisting thereof.

Section 7.07 Compensation and Indemnity.

(a) The Company shall pay to the Trustee (in its capacity as Trustee, and, to the extent it has been appointed as such, as Paying Agent and Registrar) from time to time reasonable compensation for its acceptance of this Indenture and services hereunder in accordance with a written schedule provided by the Trustee to the Company. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable and customary disbursements, advances and reasonable out-of-pocket expenses incurred or made by it in addition to the compensation for its services, except those resulting from its own negligent action, negligent failure to act or willful misconduct. Such expenses shall include the reasonable and customary compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Company shall indemnify the Trustee in its capacity against any and all losses, liabilities or reasonable out-of-pocket expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether asserted by either of the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence, bad faith or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so

114

notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may elect to have separate counsel defend the claim, but the Company will be obligated to pay the reasonable fees and expenses of such separate counsel only if the Company fails to assume the Trustee’s defense or there is a conflict of interest between the Company, on the one hand, and the Trustee, on the other hand, with respect to the claim, as reasonably determined by the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. None of the Company or the Guarantors need reimburse the Trustee for any expense or indemnity against liability or loss of the Trustee to the extent such expense, liability or loss is attributable to the negligence, bad faith or willful misconduct of the Trustee.

(d) To secure the Company’s 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, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive Satisfaction and Discharge.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

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.

Section 7.09 Successor Trustee by Merger, Etc.

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

(g) the Company will have delivered to the Trustee an Officers’ Certificate and an opinion of independent counsel, each stating that all conditions precedent relating to either the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with.

Section 8.05 Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions.

(a) Subject to Section 8.06, all money and non-callable U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and interest, but such money need not be segregated from other funds except to the extent required by law.

(c) Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable U.S. Government Obligations held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants, investment bank, or appraisal firm expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

119

Section 8.06 Repayment to the Company.

(a) Except as provided below in this Section 9.02, the Company, any Guarantor, any other obligor under the Notes and the Trustee may amend or supplement this Indenture or the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the Notes (including Additional Notes, if any) then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and, subject to Sections 6.04 and 6.07, any existing Default or Event of Default or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including Additional Notes, if any) (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). However, without the consent of the Holder of each outstanding Note affected thereby, an amendment, supplement or waiver under this Section 9.02 may not:

(1) change the Stated Maturity of the principal of, or any installment of interest on, or change to an earlier date any redemption date of, or waive a default in the payment of the principal of, premium, if any, or interest on, any such Note or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or change the coin or currency in which the principal of any such Note or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment after the Stated Maturity thereof (or, in the case of redemption, on or after the redemption date);

(5) voluntarily release, other than in accordance with this Indenture, the Guarantee of any Guarantor; or

122

(c) It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

(d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders a notice briefly describing the amendment, supplement or waiver. However, the failure to give such notice, or any defect in the notice, will not impair or affect the validity of the amendment, supplement or waiver.

Section 9.03 Compliance with Trust Indenture Act.

Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect.

Section 9.04 Revocation and Effect of Consents.

However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder unless it makes a change described in any of clauses (1) through (6) of Section 9.02(a), in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to such amendment, supplement or waiver and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

123

Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

(b) Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, Etc.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article Nine if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee.

In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and shall be fully protected in relying in good faith upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

Section 9.07 Effect of Supplemental Indentures.

Upon the execution of any amended or supplemental indenture under this Article Nine, this Indenture shall be modified in accordance therewith, and such amended or supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

ARTICLE TEN

Guarantees

Section 10.01 Guarantee.

(a) Subject to this Article Ten, each of the Guarantors hereby, jointly and severally, fully and unconditionally, guarantees, on a senior unsecured basis, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (i) the principal of, premium, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful (subject in all cases to any applicable grace period provided herein), and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

124

(b) The Guarantors hereby agree that, to the maximum extent permitted under applicable law, their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Subject to Section 6.06, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantor or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Guarantor, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Guarantee hereunder of any Guarantor, to the extent theretofore discharged, shall be reinstated in full force and effect.

(d) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders or the Trustee in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee. Each Guarantor that makes a payment or distribution under its Guarantee shall have the right to seek contribution from any non-paying Guarantor, in a pro rata amount based on the adjusted net assets of each Guarantor determined at the time of payment in accordance with GAAP, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

(e) The obligations of each Guarantor under its Guarantee pursuant to this Article Ten shall rank equally in right of payment with other existing and future senior Indebtedness of such Guarantor, and senior in right of payment to all existing and future Subordinated Indebtedness of such Guarantor.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, and the Trustee each hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount which, after giving effect to all other contingent and

125

fixed liabilities of such Guarantor, and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Article Ten, will result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. Until such time as the Notes are paid in full, each Guarantor hereby waives all rights of subrogation or contribution, whether arising by contract or operation of law (including any such right arising under federal Bankruptcy Law) or otherwise by reason of any payment by it pursuant to the provisions of this Article Ten.

Section 10.03 Guarantee Evidenced by Indenture; No Notation of Guarantee.

(a) The Guarantee of any Guarantor shall be evidenced solely by its execution and delivery of this Indenture (or, in the case of any Guarantor that is not party to this Indenture on the Issue Date, a supplemental indenture hereto) and not by an endorsement on, or attachment to, any Note or any Guarantee or notation thereof.

Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 shall be and remain in full force and effect, subject to Section 10.04, notwithstanding any failure to endorse on any Note a notation of such Guarantee.

(b) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of each of the Guarantors.

(c) Subsequent to the Issue Date, in the event a Restricted Subsidiary is required by Section 4.12 to guarantee the Company’s obligations under the Notes and this Indenture, the Company shall cause such Restricted Subsidiary to execute a supplemental indenture to this Indenture substantially in the form included in Exhibit D hereto in accordance with Section 4.12 and this Article Ten, to the extent applicable, which supplemental indenture shall be executed and delivered on behalf of such Guarantor by an Officer of such Guarantor.

Section 10.04 Releases of Guarantors.

(a) The Guarantee of a Subsidiary Guarantor will be deemed automatically and unconditionally released and discharged from all of its obligations under its Guarantee without any further action on the part of the Trustee or any Holder of the Notes:

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor (including by way of merger or consolidation) to one or more Persons that are not (either before or after giving effect to such transaction) the Parent Guarantor, the Company or a Restricted Subsidiary, if the sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor complies with Section 4.11;

(2) in connection with any sale of all of the Capital Stock of a Subsidiary Guarantor to one or more Persons that are not (either before or after giving effect to such transaction) the Parent Guarantor, the Company or a Restricted Subsidiary, if the sale of all such Capital Stock of that Subsidiary Guarantor complies with Section 4.11;

(5) if a Subsidiary Guarantor under any Credit Facility is released from its guarantee issued pursuant to the terms of any Credit Facility of the Parent Guarantor, the Company or any direct or indirect Restricted Subsidiary, and such Subsidiary Guarantor is not an obligor under any Indebtedness of the Parent Guarantor, the Company or any domestic Restricted Subsidiary other than the Notes in excess of $5.0 million in aggregate principal amount;

(6) upon the liquidation or dissolution of such Subsidiary Guarantor; provided that no Default or Event of Default has occurred and is continuing; or

(7) if Legal Defeasance or Covenant Defeasance of the Notes has been effected or Satisfaction and Discharge has been effected in accordance with the procedures set forth in Article Eight or Article Eleven, as applicable; provided that any such release and discharge pursuant to clauses (1), (2), (3), (4), (5), (6) and (7) above shall occur only to the extent that all obligations of such Subsidiary Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which secure any, Indebtedness of the Parent Guarantor, the Company and the domestic Restricted Subsidiaries (other than the Notes) having an aggregate principal amount in excess of $5.0 million shall also terminate at such time.

(b) The Parent Guarantor will be released from its obligations under this Indenture and its Guarantee only if Legal Defeasance or Covenant Defeasance of the Notes has been effected or Satisfaction and Discharge has been effected in accordance with the procedures set forth in Article Eight or Article Eleven, as applicable.

(c) Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article Ten.

(h) Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by the Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

(i) Where this Indenture provides for notice of any event to a Holder of a Global Note, such notice shall be sufficiently given if given to the Depositary for such Note (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice.

131

Section 12.05 Statements Required in Certificate or Opinion.

(a) Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA Section 314(a)(4)) shall comply with the provisions of TIA Section 314(e) and shall include:

(i) a statement that the Person making such certificate or opinion has read such covenant or condition;

(ii) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(iv) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been satisfied.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or opinion of, or representation by, counsel may be based, insofar as it relates to factual matters, upon certificates of public officials or upon a certificate or opinion of, or representations by, an Officer or Officers of the Company stating that the information with respect to such factual matters is in the possession of the Company unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Section 12.06 Rules by Trustee and Agents.

The Trustee may make reasonable rules for action by or at a meeting of the Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

132

Section 12.07 No Personal Liability of Directors, Officers, Employees and Stockholders.

No director, officer, employee, member, limited partner or stockholder of the Parent Guarantor, the Company or any Restricted Subsidiary, as such, will have any liability for any obligations of the Parent Guarantor, the Company or the Restricted Subsidiaries under the Notes, this Indenture or the Guarantees to which they are a party, 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. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Section 12.08 Governing Law.

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

Section 12.09 Trust Indenture Act Controls.

If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA Section 318(c), the imposed duties shall control.

If any provision of this Indenture modifies or excludes any provision of the TIA that may be so modified or excluded, the provision of the TIA shall be deemed to apply to this Indenture as so modified or shall be excluded, as the case may be.

Section 12.10 Successors.

All agreements of the Company in this Indenture and the Notes shall bind their successors. All agreements of the Trustee in this Indenture shall bind its successors. All agreements of each Guarantor in this Indenture shall bind its successors, except as otherwise provided in Section 5.01 or 10.04.

Section 12.11 Severability.

In case any provision in this Indenture or the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 12.12 Counterpart Originals.

The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. Delivery of an executed counterpart of this Indenture by facsimile or electronic transmission shall be equally as effective as delivery of an original executed counterpart of this Indenture. Any party delivering an executed counterpart of this Indenture by facsimile or electronic transmission also shall deliver an original executed counterpart of this Indenture, but the failure to deliver an original

133

executed counterpart shall not affect the validity, enforceability and binding effect of this Indenture.

Section 12.13 Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given, made or taken by the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing, and may be given, made or taken in connection with a purchase of, or tender offer or exchange offer for, outstanding Notes; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company if made in the manner provided in this Section 12.14.

Without limiting the generality of this Section 12.14, unless otherwise provided in or pursuant to this Indenture, (i) a Holder, including a Depositary or its nominee that is a Holder of a Global Note, may give, make or take, by an agent or agents duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or pursuant to this Indenture to be given, made or taken by the Holders, and a Depositary or its nominee that is a Holder of a Global Note may duly appoint in writing as its agent or agents members of, or participants in, such Depositary holding interests in such Global Note in the records of such Depositary; and (ii) with respect to any Global Note the Depositary for which is DTC, any consent or other action given, made or taken by an “agent member” of DTC by electronic means in accordance with the Automated Tender Offer Procedures system or other customary procedures of, and pursuant to authorization by, DTC shall be deemed to constitute the “Act” of the Holder of such Global Note, and such Act shall be deemed to have been delivered to the Company and the Trustee upon the delivery by DTC of an “agent’s message” or other notice of such consent or other action having been so given, made or taken in accordance with the customary procedures of DTC.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such witness, notary or officer the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c) Notwithstanding anything to the contrary contained in this Section 12.14 or elsewhere in this Indenture, the principal amount and serial numbers of Notes held by any

134

Holder, and the date of holding the same, shall be proved by the Securities Register of the Notes maintained by the Registrar as provided in Section 2.04.

(d) If the Company shall solicit from the Holders of the Notes any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at their option, by or pursuant to a resolution of its Board of Directors, fix in advance a record date for the determination of the Holders entitled to give, make or take such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of the Holders generally in connection therewith or the date of the most recent list of the Holders forwarded to the Trustee prior to such solicitation pursuant to Section 2.06 and not later than the date such solicitation is completed. If such a record date is fixed, then notwithstanding the second sentence of Section 9.04, any instrument embodying and evidencing such request, demand, authorization, direction, notice, consent, waiver or other Act may be executed before or after such record date, but only the Holders of record at the close of business on such record date (whether or not such Persons were Holders before, or continue to be Holders after, such record date) shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of the then outstanding Notes have given, made or taken such request, demand, authorization, direction, notice, consent, waiver or other Act, and (except to the extent otherwise required by the TIA) for that purpose the then outstanding Notes shall be computed as of such record date; provided that no such Act by the Holders of record on any record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after such record date.

(e) Subject to Section 9.04, any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note.

(f) Without limiting the foregoing, a Holder entitled hereunder to give, make or take any action hereunder with regard to any particular Note may do so itself with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

(g) For purposes of this Indenture, any action by the Holders which may be taken in writing may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

Section 12.14 Benefit of Indenture.

Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Registrar and their successors

135

hereunder, and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

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, as amended. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

If any such conditions do not occur, the Company will provide prompt written notice to the Trustee rescinding such redemption, and such redemption shall be rescinded and of no force or effect. Upon receipt of such notice, the Trustee will promptly send a copy of such notice to the Holders of the Notes to be redeemed in the same manner in which the notice of redemption was given.

(d) The Notes may also be redeemed, as a whole, following certain Change of Control Offers, at the redemption price and subject to the conditions set forth in Section 4.17 of the Indenture.

6. Mandatory Redemption. The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes. The Company may, at any time and from time to time, purchase Notes in open market purchases or negotiated transactions by tender offer or otherwise.

A1-7

(b) Under certain circumstances described in the Indenture, the Company will be required to apply the proceeds of Asset Sales to the repurchase of the Notes of Holders electing repurchase thereof pursuant to a Prepayment Offer.

8. Selection and Notice of Redemption. If less than all of the Notes are to be redeemed at any time, the Notes to be redeemed shall be selected in the manner specified in the Indenture. If any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion of any Note surrendered for redemption will be issued in the name of the Holder thereof upon cancellation of the surrendered Note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest [and Additional Interest]*, if any, shall cease to accrue on Notes or portions of them called for redemption.

9. Guarantees. The payment by the Company of the principal of and premium and interest on the Notes is fully and unconditionally guaranteed on a joint and several senior unsecured basis by each of the Guarantors to the extent set forth in the Indenture.

The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company is not required to transfer or exchange any Note selected for redemption. Also, the Company is not required to transfer or exchange any Note for a period of 15 days before a selection of Notes to be redeemed.

11. Persons Deemed Owners. The registered Holder of a Note will be treated as its owner for all purposes.

12. Amendment, Supplement and Waiver. The Indenture or the Notes may be amended or supplemented, and compliance with the provisions thereof waived, only as provided in the Indenture.

13. Defaults and Remedies. In the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization specified in the Indenture with respect to the Parent Guarantor, the Company or any Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in

Not to be included for Exchange Notes.

A1-8

aggregate principal amount of the then outstanding Notes may declare all unpaid principal of, premium, if any, and accrued interest on all Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders of the Notes) and upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of not less than a majority in aggregate principal amount of the Notes outstanding by notice to the Trustee may on behalf of the Holders of all outstanding Notes waive any past Default and its consequences under the Indenture except a Default (1) in the payment of the principal of, premium, if any, or interest on any Note (which may only be waived with the consent of each Holder of Notes affected) or (2) in respect of a covenant or provision which under the Indenture cannot be modified or amended without the consent of the Holder of each Note affected by such modification or amendment. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power conferred on it. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and, so long as any Notes are outstanding, the Company is required upon certain Officers becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

14. Trustee Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

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

16. No Recourse Against Others. No director, officer, employee, member, limited partner or stockholder of the Parent Guarantor, the Company or any Restricted Subsidiary, as such, will have any liability for any obligations of the Parent Guarantor, the Company or the Restricted Subsidiaries under the Notes, the Indenture or the Guarantees to which they are a party, or for any claim based on, in respect of, or by reason of, such obligations or their creation.
