DEFINITIONS AND INCORPORATION BY REFERENCE

Section 1.01. Definitions.

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

(1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Subsidiary of such specified Person, regardless of whether such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person, but excluding Indebtedness which is extinguished, retired or repaid in connection with such Person merging with or becoming a Subsidiary of such specified Person; and

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

“Additional Assets” means:

(1) any property or assets (other than Indebtedness and Capital Stock) to be used by the Company or a Restricted Subsidiary in a Related Business;

(3) 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 (2) and (3), such Restricted Subsidiary is primarily engaged in a Related Business.

“Additional Interest” means additional interest owed to Holders pursuant to a Registration Rights Agreement.

“Additional Notes” means any Notes issued under this Indenture in addition to the Original Notes, including any Exchange Notes issued in exchange for such Additional Notes, having the same terms in all respects as the Original Notes, or in all respects except with respect to the issue date, issue price and the first interest payment date after the issuance of such Additional Notes.

(a)

(i) discounted future net revenue from proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with Commission guidelines before any state or federal income taxes, as estimated in a reserve report prepared as of the end of the Company’s most recently completed fiscal year, which reserve report is prepared or reviewed by independent petroleum engineers, as increased by, as of the date of determination, the discounted future net revenue of:

(A) estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to acquisitions consummated since the date of such year-end reserve report, and

(B) estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries attributable to extensions, discoveries and other additions and upward determinations of estimates of proved crude oil and natural gas reserves (including previously estimated development costs incurred during the period and the accretion of discount since the prior year end) due to exploration, development or exploitation, production or other activities which reserves were not reflected in such year-end reserve report, in the case of the determination made under each of clauses (A) and (B) above, calculated in accordance with Commission guidelines (utilizing the prices utilized in such year-end reserve report) before any state or federal income taxes, and decreased by, as of the date of determination, the discounted future net revenue attributable to:

(C) estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such year-end reserve report produced or disposed of since the date of such year-end reserve report (before any state or federal income taxes), and

(D) reductions in the estimated proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries reflected in such year-end reserve report since the date of such year-end reserve report attributable to downward determinations of estimates of proved crude oil and natural gas reserves due to exploration, development or exploitation, production or other activities conducted or otherwise occurring since the date of such year-end reserve report, in each case calculated in accordance with Commission guidelines (utilizing the prices utilized in such year-end reserve report) before any state or federal income taxes;

provided, however, that, in the case of each of the determinations made pursuant to clauses (A) through (D), such increases and decreases shall be as estimated by the Company’s engineers;

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

minus

(b)

to the extent not otherwise taken into account in the immediately preceding clause (a), the sum of:

(i) minority interests;

(ii) any net gas or other balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest audited financial statements;

(iii) the discounted future net revenue, calculated in accordance with Commission guidelines (utilizing the same prices utilized in the Company’s year-end reserve report) before any state or federal income taxes, attributable to reserves subject to participation interests, royalty interests, overriding royalty interests, net profits interests or other interests of third parties, pursuant to participation, partnership, vendor financing or other agreements then in effect, or which otherwise are required to be delivered to third parties;

(iv) the discounted future net revenue, calculated in accordance with Commission guidelines (utilizing the same prices utilized in the Company’s year-end reserve report) before any state or federal income taxes, attributable to reserves that are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified with respect thereto; and

(v) the discounted future net revenue, calculated in accordance with Commission guidelines before any state or federal income taxes, attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production included in determining the discounted future net revenue specified in the immediately preceding clause (a)(i) (utilizing the same prices utilized in the Company’s year-end reserve report), would be necessary to satisfy fully the obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto.

The Company in issuing the Notes may use “CUSIP” and “CINS” numbers, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption or exchange or in Change of Control Offers and Asset Sale Offers as a convenience to Holders, the notice to state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or exchange or Offer to Purchase. The Company will promptly notify the Trustee of any change in the CUSIP or CINS numbers.

Section 2.09. Registration, Transfer and Exchange. (a) The Notes will be issued in registered form only, without coupons, and the Company shall cause the Trustee to maintain a register (the “Register”) of the Notes, for registering the record ownership of the Notes by the Holders and transfers and exchanges of the Notes.

(b) (1) Each Global Note will be registered in the name of the Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend.

(2) Each Global Note will be delivered to the Trustee as custodian for the Depositary. Transfers of a Global Note (but not a beneficial interest therein) will be limited to transfers thereof in whole, but not in part, to the Depositary, its successors or their respective nominees, except as set forth in Section 2.09(b)(5).

(3) Agent Members will have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Neither the Company, any Subsidiary Guarantor, the Trustee nor any of their respective agents has or will have any responsibility for:

(A) Any aspect of the records of the Depositary, any Agent Member, or anyone who clears through or maintains an account with an Agent Member relating to or payments made on account of beneficial ownership interest in the Global Note or for maintaining, supervising or reviewing any of the records of the Depositary, any Agent Member or anyone who clears through or maintains an account with an Agent Member relating to the beneficial ownership interests in the Global Note;

(B) Any delay by the Depositary or any of its Agent Members in identifying the beneficial owners of the Notes (and the Company, any Subsidiary Guarantor, the Trustee and any of their respective agents may conclusively rely on and will be protected in relying on instructions from the Depositary or its nominee for all purposes); or

(C) Any other matter relating to the actions and practices of the Depositary, any Agent Members or anyone who clears through or maintains an account with an Agent Member.

(4) Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent Member) to take any action which a Holder is entitled to take under this Indenture or the Notes, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

(5) If

(A) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for a Global Note or has ceased to be 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

(B) a Default or Event of Default has occurred and is continuing and the Depositary notifies the Trustee of its decision to exchange the Global Notes for Certificated Notes,

the Trustee will promptly exchange each beneficial interest in the Global Note for one or more Certificated Notes issued in exchange by the Company in authorized denominations having an equal aggregate principal amount registered in the name of the owner of such beneficial interest, as identified to the Trustee by the Depositary, and thereupon the Global Note will be deemed canceled. If such Note does not bear the Restricted Legend, then the Certificated Notes issued in exchange therefor will not bear the Restricted Legend. If such Note bears the Restricted Legend, then the Certificated Notes issued in exchange therefor will bear the Restricted Legend, provided that any Holder of any such Certificated Note issued in exchange for a beneficial interest in an Offshore Global Note will have the right upon presentation to the Trustee of a duly completed Certificate of Beneficial Ownership after the Restricted Period to exchange such Certificated Note for a Certificated Note of like tenor and amount that does not bear the Restricted Legend, registered in the name of such Holder.

(d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized

denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by Section 2.10. The Trustee will promptly register any transfer or exchange that meets the requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that

(x) no transfer or exchange will be effective until it is registered in such register and

(y) the Trustee will not be required (i) to issue, register the transfer of or exchange any Note for a period of 15 days before a selection of Notes to be redeemed or purchased pursuant to a Change of Control Offer or an Asset Sale Offer, (ii) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of any Note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to a Change of Control Offer or an Asset Sale Offer is to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to register the transfer of or exchange any Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will treat the Person in whose name the Note is registered as the owner and Holder thereof for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary.

From time to time the Company will execute and the Trustee will authenticate additional Notes as necessary in order to permit the registration of a transfer or exchange in accordance with this Section.

No service charge will be imposed in connection with any transfer or exchange of any Note, 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 a transfer tax or other similar governmental charge payable upon exchange pursuant to subsection (b)(5)).

(e) (1) Global Note to Global Note. If a beneficial interest in a Global Note is transferred or exchanged for a beneficial interest in another Global Note, the Trustee will (x) record a decrease in the principal amount of the Global Note being transferred or exchanged equal to the principal amount of such transfer or exchange and (y) record a like increase in the principal amount of the other Global Note. Any beneficial interest in one Global Note that is transferred to a Person who takes delivery in the form of an interest in another Global Note, or exchanged for an interest in another Global Note, will, upon transfer or exchange, cease to be an interest in such Global Note and become an interest in the other Global Note and, accordingly, will thereafter be subject to all transfer and exchange restrictions, if any, and other procedures applicable to beneficial interests in such other Global Note for as long as it remains such an interest.

(2) Global Note to Certificated Note. If a beneficial interest in a Global Note is transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease in the principal amount of such Global Note equal to the principal amount of such

transfer or exchange and (y) deliver one or more new Certificated Notes in authorized denominations having an equal aggregate principal amount to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name of such transferee or owner, as applicable.

(3) Certificated Note to Global Note. If a Certificated Note is transferred or exchanged for a beneficial interest in a Global Note, the Trustee will (x) cancel such Certificated Note, (y) record an increase in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (z) in the event that such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

(4) Certificated Note to Certificated Note. If a Certificated Note is transferred or exchanged for another Certificated Note, the Trustee will (x) cancel the Certificated Note being transferred or exchanged, (y) deliver one or more new Certificated Notes in authorized denominations having an aggregate principal amount equal to the principal amount of such transfer or exchange to the transferee (in the case of a transfer) or the Holder of the canceled Certificated Note (in the case of an exchange), registered in the name of such transferee or Holder, as applicable, and (z) if such transfer or exchange involves less than the entire principal amount of the canceled Certificated Note, deliver to the Holder thereof one or more Certificated Notes in authorized denominations having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

Section 2.10. Restrictions on Transfer and Exchange. (a) The transfer or exchange of any Note (or a beneficial interest therein) may only be made in accordance with this Section and Section 2.09 and, in the case of a Global Note (or a beneficial interest therein), the applicable rules and procedures of the Depositary. The Trustee shall refuse to register any requested transfer or exchange that the Trustee knows does not comply with the preceding sentence.

(b) Subject to paragraph (c), the transfer or exchange of any Note (or a beneficial interest therein) of the type set forth in column A below for a Note (or a beneficial interest therein) of the type set forth opposite in column B below may only be made in compliance with the certification requirements (if any) described in the clause of this paragraph set forth opposite in column C below.

In the event that (i) the requested transfer or exchange takes place after the expiration of the Restricted Period and a duly completed Regulation S Certificate is delivered to the Trustee or (ii) a Certificated Note that does not bear the Restricted Legend is surrendered for transfer or exchange, upon transfer or exchange the Trustee will deliver a Certificated Note that does not bear the Restricted Legend.

(1) after such Note is eligible for resale pursuant to Rule 144 under the Securities Act (or a successor provision) without the need for current public information; provided that the Company has provided the Trustee with an Officers’ Certificate to that effect, and the Company may require from any Person requesting a transfer or exchange in reliance upon this clause (1) an opinion of counsel and any other reasonable certifications and evidence in order to support such certificate; or

(2) (x) sold pursuant to an effective registration statement, pursuant to the Registration Rights Agreement or otherwise or (y) which is validly tendered for exchange into an Exchange Note pursuant to an Exchange Offer.

Any Certificated Note delivered in reliance upon this paragraph will not bear the Restricted Legend.

(d) The Trustee will retain copies of all certificates, opinions and other documents received in connection with the transfer or exchange of a Note (or a beneficial interest therein), and the Company will have the right to inspect and make copies thereof at any reasonable time upon written notice to the Trustee.

ARTICLE 3

REDEMPTION; OFFER TO PURCHASE

Section 3.01. Optional Redemption. (a) Except as described below or in Section 4.11, the Notes are not redeemable until December 1, 2016. On and after December 1, 2016, the Company may redeem all or a part of the Notes, from time to time, at the following redemption prices (expressed as a percentage of principal amount) plus accrued and unpaid interest, if any, on the Notes redeemed to the applicable redemption date (subject to the rights of Holders of Notes on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period beginning on December 1 of the years indicated below:


Year	Percentage
2016		104.438	%
2017		102.219	%
2018 and thereafter		100.000	%

(b) At any time or from time to time prior to December 1, 2016, the Company may also redeem all or a part of the Notes at a redemption price equal to the Make-Whole Price, subject to the rights of Holders of Notes on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date.

Section 3.02. Redemption with Proceeds of Public Equity Offering. (a) Prior to December 1, 2015, the Company may on any one or more occasions redeem up to 35% of the principal amount of the Notes with all or a portion of the net cash proceeds of one or more Equity Offerings at a redemption price equal to 108.875% of the principal amount thereof, plus accrued and unpaid interest, if any, on the Notes redeemed to the redemption date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date); provided that

(1) at least 65% of the aggregate principal amount of the Notes originally issued under the Indenture (including Additional Notes, but excluding Notes held by the Company and its Subsidiaries) remains outstanding after each such redemption; and

(2) the redemption occurs within 90 days after the closing of such Equity Offering.

Section 3.03. Method and Effect of Redemption. (a) If the Company elects to redeem Notes, it must notify the Trustee of the redemption date and the principal amount of Notes to be redeemed by delivering an Officers’ Certificate at least 60 days before the redemption date (unless a shorter period is satisfactory to the Trustee). If fewer than all of the Notes are being redeemed, the Officers’ Certificate must also specify a record date not less than 15 days after the date of the notice of redemption is given to the Trustee, and the Trustee will select the Notes to be redeemed on a pro rata basis, subject to adjustments so that no Notes are redeemed in an unauthorized denomination (or, in the case of Global Notes, the Notes to be redeemed will be selected in accordance with the Depositary’s applicable procedures), unless otherwise required by law or applicable stock exchange requirements. Notes redeemed in part must be redeemed in denominations of $2,000 principal amount and higher integral multiples of $1,000 (subject to the procedures of the Depositary). The Trustee will notify the Company promptly of the Notes or portions of Notes to be called for redemption. Notices of redemption must be sent by the Company or at the Company’s request, by the Trustee in the name and at the expense of the Company, to Holders whose Notes are to be redeemed at least 30 days but not more than 60 days before the redemption date in the case of Global Notes, to the Depositary in accordance with the procedures of the Depositary and in the case of certificated Notes, by first class mail, or delivered electronically if held at DTC, to each Holder of Notes to be redeemed at its registered address, except notices of redemption may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture.

(b) The notice of redemption will identify the Notes to be redeemed and will include or state the following:

(1) the redemption date;

(2) the redemption price, or the method by which it will be calculated;

(3) the place or places where Notes are to be surrendered for redemption;

(4) Notes called for redemption must be so surrendered in order to collect the redemption price;

(5) on the redemption date the redemption price will become due and payable on Notes called for redemption, and interest on Notes called for redemption will cease to accrue on and after the redemption date;

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

(7) if any Note contains a CUSIP or CINS number, no representation is being made as to the correctness of the CUSIP or CINS number either as printed on the Notes or as contained in the notice of redemption and that the Holder should rely only on the other identification numbers printed on the Notes.

(c) At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date (or such shorter period of time, subject to Section 3.03(a), as may be acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in this Section.

(d) Once notice of redemption is sent to the Holders, Notes called for redemption become due and payable at the redemption price on the redemption date. Notices of redemption may not be subject to conditions precedent. Upon surrender of any Note redeemed in part, the Holder will receive a new Note equal in principal amount to the unredeemed portion of the surrendered Note.

(e) Unless the Company defaults in the payment of the redemption price, interest, if any, will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date.

ARTICLE 4

COVENANTS

Section 4.01. Payment of Notes. (a) The Company agrees to pay the principal of and interest on the Notes on the dates and in the manner provided in the Notes and this Indenture. Not later than 10:00 A.M. (New York City time) on the due date of any principal of or interest on any Notes, or any redemption or purchase price of the Notes, the Company will deposit with the Trustee (or Paying Agent) money in immediately available funds sufficient to pay such amounts, provided that if the Company or any Affiliate of the Company is acting as Paying Agent, it will, on or before each due date, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient to pay such amounts until paid to such Holders or otherwise disposed of as provided in this Indenture. In each case the Company will promptly notify the Trustee of its compliance with this paragraph.

(b) An installment of principal or interest will be considered paid on the date due if the Trustee (or Paying Agent, other than the Company or any Affiliate of the Company) holds on that date money designated for and sufficient to pay the installment. If the Company or any Affiliate of the Company acts as Paying Agent, an installment of principal or interest will be considered paid on the due date only if paid to the Holders.

(c) The Company agrees to pay interest on overdue principal, and, to the extent lawful, overdue installments of interest at the rate per annum specified in the Notes.

(d) Payments in respect of the Notes represented by the Global Notes are to be made by wire transfer of immediately available funds to the accounts specified by the Holders of the Global Notes. With respect to Certificated Notes, the Company will, through its Paying Agent, make all payments by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each Holder’s registered address.

Section 4.02. Maintenance of Office or Agency. The Company will maintain in the United States an office or agency where Notes may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and demands (but not service of process) to or upon the Company in respect of the Notes and this Indenture may be served. The Company hereby initially designates the Corporate Trust Office of the Trustee as such office of the Company. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served to the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be surrendered or presented for any of such purposes and may from time to time rescind such designations. Further, if at any time when Notes in certificated form are outstanding there shall be no such office or agency in the City of New York where such Notes may be presented or surrendered for payment, the Company shall forthwith designate and maintain such an office or agency in the City of New York, in order that the Notes (after taking into consideration the payment requirements of DTC) shall at all times be payable in the City of New York. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Section 4.03. Existence. The Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence and the existence of each of its Restricted Subsidiaries in accordance with their respective organizational documents, and the material rights, licenses and franchises of the Company and each Restricted Subsidiary, provided that the Company is not required to preserve any such right, license or franchise, or the existence of any Restricted Subsidiary, if the maintenance or preservation thereof is, in the judgment of the Company, no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole; and provided further that this Section does not prohibit any transaction otherwise permitted by Section 4.12 or Article 5.

Section 4.04. Payment of Taxes and Other Claims. The Company will pay or discharge, and cause each of its Subsidiaries to pay or discharge before the same become delinquent (i) all material taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or its income or profits or property, and (ii) all material lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon the property of the Company or any Subsidiary, other than any such tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and for which adequate reserves have been established.

Section 4.05. Maintenance of Properties and Insurance. (a) The Company will cause all material properties used or useful in the conduct of its business or the business of any of its Restricted Subsidiaries to be maintained and kept in good condition, repair and working order as in the judgment of the Company may be necessary so that the business of the Company and its

Restricted Subsidiaries may be properly and advantageously conducted at all times; provided that nothing in this Section prevents the Company or any Restricted Subsidiary from discontinuing the use, operation or maintenance of any of such properties or disposing of any of them, if such discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole.

(b) The Company will provide or cause to be provided, for itself and its Restricted Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds customarily insured against by corporations similarly situated and owning like properties with reputable insurers, in such amounts, with such deductibles and by such methods as are customary for corporations similarly situated in the industry in which the Company and its Restricted Subsidiaries are then conducting business.

Section 4.06. Incurrence of Indebtedness and Issuance of Preferred Stock. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to directly or indirectly create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur;” with “incurrence” having a correlative meaning) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired Debt) and issue Disqualified Stock, and Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) and issue preferred stock, if the Company’s Fixed Charge Coverage Ratio for its most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.

(b) Notwithstanding the foregoing, paragraph (a) of this Section 4.06 will not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any Disqualified Stock or preferred stock described below (collectively, “Permitted Debt”):

(1) the incurrence by the Company and any Restricted Subsidiary of Indebtedness under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (i) $300 million and (ii) the sum of $150 million plus an amount equal to 30.0% of Adjusted Consolidated Net Tangible Assets of the Company, determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom;

(2) the incurrence by the Company and its Restricted Subsidiaries of Existing Indebtedness;

(3) the incurrence by the Company and the Subsidiary Guarantors of Indebtedness represented by the Notes and the Subsidiary Guarantees to be issued on the Issue Date and the Exchange Notes and the related Subsidiary Guarantees to be issued pursuant to the Registration Rights Agreement in exchange therefor;

(4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation, improvement, deployment, refurbishment or modification of property, plant or equipment or furniture, fixtures and equipment, in each case, used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of (A) $15 million and (B) 2.5% of Adjusted Consolidated Net Tangible Assets of the Company, determined as of the date of the incurrence of such Indebtedness;

(5) the incurrence or issuance by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company, or Indebtedness (other than intercompany Indebtedness) or preferred stock of any Restricted Subsidiary, in each case that was permitted by this Indenture to be incurred or issued under paragraph (a) of this Section 4.06 clauses (2), (3), or (10) of this paragraph (b) or this clause (5);

(6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (A) if the Company or any Subsidiary Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Subsidiary Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations then due with respect to the Notes, in the case of the Company, or the Subsidiary Guarantee, in the case of a Subsidiary Guarantor; and (B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any preferred stock; provided, however, that:

(A) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary; and

(B) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary, will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (7);

(8) the incurrence of obligations of the Company or a Restricted Subsidiary pursuant to Hedging Obligations entered into in the ordinary course of business and not for speculative purposes;

(9) the Guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or a Restricted Subsidiary that was permitted to be incurred by this Section 4.06; provided that in the case of a Guarantee by a Restricted Subsidiary that is not a Subsidiary Guarantor, such Restricted Subsidiary would have been permitted to incur the Indebtedness being Guaranteed under this covenant, and provided further that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes, then the Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed;

(10) the incurrence by the Company or any Restricted Subsidiary of Permitted Acquisition Indebtedness;

(11) the incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days;

(12) the incurrence by the Company or any Restricted Subsidiary of Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its Restricted Subsidiaries;

(13) the incurrence of in-kind obligations relating to net oil and natural gas balancing positions arising in the ordinary course of business;

(14) the incurrence of any obligations in respect of completion bonds, performance bonds, bid bonds, appeal bonds, surety bonds, bankers acceptances, letters of credit, insurance obligations or bonds and other similar bonds and obligations incurred by the Company or any Restricted Subsidiary in the ordinary course of business and any Guarantees or letters of credit functioning as or supporting any of the foregoing bonds or obligations;

(15) the incurrence of any obligation arising from agreements of the Company or a Restricted Subsidiary providing for indemnification, Guarantee, adjustment of purchase price, holdback, contingency payment obligation based on the performance of the acquired or disposed asset or similar obligations, in each case, incurred or assumed in connection with the acquisition or disposition of any business, asset or Equity Interests of a Restricted Subsidiary; and

(16) the incurrence by the Company or any of the Restricted Subsidiaries of Indebtedness in an aggregate principal amount that, when taken together with all other Indebtedness of the Company and its Restricted Subsidiaries outstanding on the date of such incurrence (other than Indebtedness permitted by clauses (1) through (15) above or Section 4.06(a)) and any Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (16) does not exceed the greater of (a) $15 million and (b) 2.5% of Adjusted Consolidated Net Tangible Assets of the Company, determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom.

(c) The Company will not incur, and will not permit any Subsidiary Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Subsidiary Guarantee, on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis.

(d) For purposes of determining compliance with this Section 4.06, (1) in the event that an item of proposed Indebtedness, Disqualified Stock or preferred stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) of paragraph (b), or is entitled to be incurred or issued pursuant to paragraph (a), the Company will be permitted to divide and classify such item on the date of its incurrence or issuance, or later divide and reclassify all or a portion of such item, in any manner that complies with this Section 4.06, except that all Indebtedness outstanding on the Issue Date (after giving effect to the use of proceeds from the offering of the Initial Notes) under the Senior Credit Agreement shall be deemed Incurred on the Issue Date under clause (1) of paragraph (b) above and may not be reclassified. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, fluctuations in the termination value of Hedging Obligations, and the payment of dividends on Disqualified Stock or preferred stock in the form of additional Disqualified Stock or preferred stock of the same class will be deemed not to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred stock for purposes of this Section 4.06; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued.

(e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term

Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 4.06, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.06 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies.

Section 4.07. Restricted Payments. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company and other than dividends or distributions payable to the Company or any Restricted Subsidiary);

(2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, any such purchase, redemption, acquisition or retirement made in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent company of the Company;

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Subordinated Debt, except a payment of interest or principal at or within three Business Days prior to or after the Stated Maturity thereof (excluding (A) any intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries or (B) the purchase or other acquisition of Subordinated Debt acquired in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of such purchase or other acquisition); or

(4) make any Restricted Investment;

(all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment:

(i) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;

(ii) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the most recently ended four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.06(a); and

(iii) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries since the Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8) and (10) of paragraph (b) below), is equal to or less than the sum, without duplication, of:

(A) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from October 1, 2012 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

(B) 100% of (i) (a) the aggregate net cash proceeds and (b) the Fair Market Value of (x) marketable securities (other than marketable securities of the Company or an Affiliate of the Company), (y) Capital Stock of a Person (other than the Company or an Affiliate of the Company) engaged primarily in any Related Business and (z) other assets used or useful in any Related Business, in each case received by the Company or a Restricted Subsidiary since the Issue Date as a contribution to the Company’s common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company), (ii) with respect to Indebtedness that is incurred on or after the Issue Date, the amount by which such Indebtedness of the Company or any of its Restricted Subsidiaries is reduced on the Company’s consolidated balance sheet upon the conversion or exchange after the Issue Date of any such Indebtedness into or for Equity Interests of the Company (other than Disqualified Stock), and (iii) the aggregate net cash proceeds, if any, received by the Company or any of its Restricted Subsidiaries upon any conversion or exchange described in clause (i) or (ii) above; plus

(C) with respect to Restricted Investments made by the Company and its Restricted Subsidiaries after the Issue Date, an amount equal to the sum, without duplication, of (i) the net reduction in such Restricted Investments in any Person resulting from (a) repayments of loans or advances, or other transfers of assets, in each case to the Company or any Restricted Subsidiary, (b) other repurchases, repayments or redemptions of such Restricted Investments, (c) the sale of any such Restricted Investment to a purchaser other than the Company or a

Subsidiary of the Company or (d) the release of any Guarantee (except to the extent any amounts are paid under such Guarantee) that constituted a Restricted Investment plus (ii) with respect to any Unrestricted Subsidiary designated as such after the Issue Date that is redesignated as a Restricted Subsidiary after the Issue Date, the Fair Market Value of the Company’s Investment in such Subsidiary held by the Company or any of its Restricted Subsidiaries at the time of such redesignation; plus

(D) 100% of any dividends received by the Company or a Restricted Subsidiary after the Issue Date from an Unrestricted Subsidiary, to the extent such dividends were not otherwise included in the Consolidated Net Income of the Company for such period.

(b) The preceding provisions will not prohibit:

(1) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of this Indenture;

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds from the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock and other than Equity Interests issued or sold to an employee stock ownership plan, option plan or similar trust to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or Guaranteed by the Company or any of its Restricted Subsidiaries unless such loans have been repaid with cash on or prior to the date of determination) or from the substantially concurrent contribution of common equity capital to the Company; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (iii)(B) of paragraph (a) of this Section 4.07;

(3) the purchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Debt (including the payment of any required premium and any fees and expenses incurred in connection with such purchase, redemption, defeasance or other acquisition or retirement) with the net cash proceeds from a substantially concurrent incurrence of Permitted Refinancing Indebtedness;

(7) as long as no Default has occurred and is continuing or would be caused thereby, the declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the Company or any class or series of preferred stock of any Restricted Subsidiary issued on or after the Issue Date in accordance with the Fixed Charge Coverage Ratio test set forth in Section 4.06(a);

(8) the payment of any dividend (or, in the case of any partnership or limited liability company, any similar distribution) by a Restricted Subsidiary to the holders of Equity Interests (other than Disqualified Stock) of such Restricted Subsidiary; provided that such dividend or similar distribution is paid to all holders of such Equity Interests on a pro rata basis based on their respective holdings of such Equity Interests;

(9) purchases of Subordinated Debt at a purchase price not greater than (A) 101% of the principal amount of such Subordinated Debt and accrued and unpaid interest thereon in the event of a Change of Control or (B) 100% of the principal amount of such Subordinated Debt and accrued and unpaid interest thereon in the event of an Asset Sale in connection with any change of control offer or asset sale offer required by the terms of such Subordinated Debt, but only if:

(i) in the case of a Change of Control, the Company has first offered to purchase the Notes and complied with and fully satisfied its other obligations under Section 4.11, including purchasing all Notes tendered in such offer; or

(ii) in the case of an Asset Sale, the Company has complied with and fully satisfied its obligations under Section 4.12, including purchasing all Notes tendered in an Asset Sale Offer;

(11) as long as no Default has occurred and is continuing at the time of such Restricted Payment or would be caused thereby, other Restricted Payments in an aggregate amount not to exceed $20 million since the Issue Date.

(c) The amount of all Restricted Payments (other than cash) shall be the Fair Market Value, on the date of such Restricted Payment, of the Restricted Investment proposed to be made or the asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. The Fair Market Value of any cash Restricted Payment shall be its face amount, and the Fair Market Value of any non-cash Restricted Payment shall be determined in accordance with the definition of that term.

(d) For purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more than one of the exceptions described in clauses (1) through (11) of paragraph (b) hereof or is entitled to be made pursuant to paragraph (a) hereof, the Company shall, in its sole discretion, classify such Restricted Payment, or later classify, reclassify or re-divide all or a portion of such Restricted Payment, in any manner that complies with this Section 4.07.

Section 4.08. Limitation on Liens. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or permit to exist any Lien (the “Initial Lien”), other than Permitted Liens, upon any of its property or assets (including Capital Stock and Indebtedness of any Subsidiaries of the Company and including any income or profits from such property or assets), whether owned on the Issue Date or thereafter acquired, which Lien secures any Subordinated Debt or other Indebtedness, unless:

(1) in the case of Liens securing Subordinated Debt of the Company or a Subsidiary Guarantor, the Notes or Subsidiary Guarantee, as applicable, are secured by a Lien on such property or assets on a senior basis to the Subordinated Debt so secured with the same priority as the Notes or such Subsidiary Guarantee, as applicable, has to such Subordinated Debt until such time as such Subordinated Debt is no longer so secured by a Lien; and

(2) in the case of Liens securing other Indebtedness of the Company or a Restricted Subsidiary, the Notes or Subsidiary Guarantees, as applicable, are secured by a Lien on such property or assets on an equal and ratable basis with the other Indebtedness so secured until such time as such other Indebtedness is no longer so secured by a Lien.

(b) Any Lien securing the Notes or Subsidiary Guarantees created pursuant to clause (2) of paragraph (a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the unconditional release and discharge of the Initial Lien.

Section 4.09. Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries;

(2) make loans or advances to the Company or any of its Restricted Subsidiaries; or

(3) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

(b) The provisions of paragraph (a) will not apply to encumbrances or restrictions existing under, by reason of or with respect to:

(1) the Senior Credit Agreement in effect on the Issue Date and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings thereof; provided that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith judgment of the Chief Executive Officer and the Chief Financial Officer of the Company, no more restrictive, taken as a whole, than those contained in the applicable agreements or instruments as in effect on the Issue Date;

(2) this Indenture, the Notes and the Subsidiary Guarantees;

(3) applicable law, rule, regulation, order, approval, permit or similar restriction;

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings thereof; provided, that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial Officer of the Company, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(5) customary non-assignment provisions in contracts, leases, licenses and sublicenses (including, without limitation, licenses of intellectual property) entered into in the ordinary course of business and 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 Company or any Restricted Subsidiary;

(6) any agreement for the sale or other disposition of the Equity Interests in, or all or substantially all of the properties or assets of, a Restricted Subsidiary, that restricts distributions by the applicable Restricted Subsidiary pending the sale or other disposition;

(7) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial Officer of the Company, not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(8) Liens permitted to be incurred under Section 4.08 that limit the right of the debtor to dispose of the assets subject to such Liens and the security documents relating thereto;

(9) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred stock is permitted pursuant to Section 4.06 and the terms of such preferred stock do not expressly restrict the ability of a Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital Stock);

(10) instruments governing other Indebtedness of the Company or any of its Restricted Subsidiaries permitted to be incurred in accordance with Section 4.06; provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness are not materially less favorable to the Company and its Restricted Subsidiaries, taken as a whole, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial Officer of the Company, than the provisions contained in the Senior Credit Agreement or any other agreement described in clause (1) above, as in effect on the Issue Date, or this Indenture;

(11) Indebtedness incurred or Capital Stock issued by any Restricted Subsidiary in accordance with this Indenture, provided that the restrictions contained in the agreements or instruments governing such Indebtedness or Capital Stock (A) apply only in the event of a payment default or a default with respect to a financial covenant in such agreement or instrument or (B) will not materially affect the Company’s ability to pay all principal, interest and premium, if any, on the Notes, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial Officer of the Company;

(12) Hedging Obligations permitted from time to time under this Indenture entered into in the ordinary course of business and not for speculative purposes;

(15) Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments to the extent such encumbrance or restriction restricts the transfer of the property (including Capital Stock) subject to such Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments.

Section 4.10. Future Subsidiary Guarantees. (a) If, after the Issue Date, any Restricted Subsidiary that is not already a Subsidiary Guarantor Guarantees (or otherwise becomes liable for) Indebtedness of the Company or a Subsidiary Guarantor under a Credit Facility then such Subsidiary will become a Subsidiary Guarantor by executing and delivering a supplemental indenture, in the form of Exhibit B, to the Trustee within 20 days of the date on which it Guarantees such Indebtedness.

(b) The Subsidiary Guarantee of any such Subsidiary Guarantor will subject to the release provisions and the other limitations described in Article 10.

Section 4.11. Offer to Repurchase upon a Change of Control. (a) If a Change of Control occurs, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that Holder’s Notes pursuant to an offer (a “Change of Control Offer”) on the terms set forth in this Section. In the Change of Control Offer, the Company will offer a payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase (the “Change of Control Payment Date”), subject to the rights of Holders of Notes on the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, or, at the Company’s option, prior to such Change of Control but after it is publicly announced, the Company will deliver electronically, if held at DTC, or mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.11 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the Change of Control Payment Date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed or such later date as is necessary to comply with requirements under the Exchange Act;

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer the Notes by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the Business Day immediately preceding the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the Business Day immediately preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have all or a portion of the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess of $2,000.

(b) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section by virtue of such compliance.

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

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

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

(d) The Paying Agent will promptly mail or wire transfer to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note issued by the Company will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date unless the Company defaults in making the Change of Control Payment.

(e) The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(f) Notwithstanding anything to the contrary in this Section, the Company will not be required to make a Change of Control Offer upon a Change of Control if (i) a third party makes the Change of Control Offer in the manner, at the price, 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 properly tendered and not withdrawn under the Change of Control Offer, or (ii) the Company has given notice of redemption pursuant to Section 3.01 of this Indenture with respect to all outstanding Notes unless and until there is a Default in payment of the applicable redemption price.

(g) A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. Notes repurchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be retired and cancelled, at the Company’s option. Notes purchased by a third party pursuant to clause (f) of this Section will have the status of Notes issued and outstanding.

(h) In the event that Holders of at least 90% of the aggregate principal amount of the outstanding Notes accept a Change of Control Offer and the Company (or any third party making such Change of Control Offer, in lieu of the Company, as described in paragraph (f) of this Section) purchases all of the Notes held by such Holders, 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 a Change of Control Payment Date, to redeem all, but not less than all, of the Notes that remain outstanding at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain outstanding, to the date of redemption (subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date).

(i) The provisions of this Section that require the Company to make a Change of Control Offer following a Change of Control will be applicable regardless of whether any other provisions of this Indenture are applicable.

Section 4.12. Asset Sales. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company (or the 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 or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in respect of such Asset Sale by the Company or such Restricted Subsidiary, taken together with all other Asset Sales since the Issue Date on a cumulative basis, is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(A) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities, Subordinated Debt and any obligations in respect of preferred stock) that are assumed by the transferee of any such assets or Equity Interests pursuant to (i) a customary novation agreement (or other legal documentation with the same effect) that includes a full release of the Company

or such Restricted Subsidiary from any and all liability therefor or (ii) an assignment agreement that includes, in lieu of such release, the agreement of the transferee or its parent company to indemnify and hold harmless the Company or such Restricted Subsidiary from and against any loss, liability or other cost in respect of such assumed liability;

(B) Liquid Securities; and

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

(1) to repay, prepay, redeem or purchase (x) Indebtedness and other Obligations under a Credit Facility; provided that any such action in respect of a revolving Credit Facility shall be accompanied by a reduction of the related commitments, (y) any Indebtedness that was secured by the assets sold in such Asset Sale or (z) other Senior Debt;

(2) to invest in Additional Assets; or

(3) to make capital expenditures in respect of a Related Business of the Company or any of its Restricted Subsidiaries;

provided that the Company or the applicable Restricted Subsidiary will be deemed to have complied with this paragraph with respect to an Asset Sale if, within 365 days after such Asset Sale, the Company or such Restricted Subsidiary shall have commenced and not completed or abandoned an expenditure or Investment, or a binding agreement with respect to an expenditure or Investment, in compliance with this, and that expenditure or Investment is completed within one year and six months after the date of such Asset Sale.

However, pending application or investment of such Net Proceeds as provided in clauses (1) through (3) above, such Net Proceeds may be applied to temporarily reduce revolving credit Indebtedness. An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (1) through (3) above within the time period set forth above will constitute “Excess Proceeds.”

(c) Within ten Business Days after the aggregate amount of Excess Proceeds exceeds $25 million, the Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If

the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will use the Excess Proceeds to purchase the Notes and such other pari passu Indebtedness on a pro rata basis subject to adjustments so that no Notes or other pari passu Indebtedness is repurchased in part in an unauthorized denomination. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(d) Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by Section 4.11 and/or Section 5.01 and not by this Section 4.12.

(e) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.12, or compliance with this Section 4.12 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sales provisions of this Indenture by virtue of such compliance.

(f) In the event that, pursuant to this Section 4.12, the Company is required to commence an Asset Sale Offer, it will follow the procedures specified below:

(1) The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable, subject to adjustments so that no Notes or other pari passu Indebtedness is repurchased in part in an unauthorized denomination) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer.

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

(3) Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, or delivered electronically if held at DTC, a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(A) that the Asset Sale Offer is being made pursuant to this Section 4.12 and the length of time the Asset Sale Offer will remain open;

(B) the Offer Amount, the purchase price and the Purchase Date;

(D) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

(E) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000 only;

(F) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer the Notes by book-entry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice prior to the close of business on the Business Day immediately preceding the Purchase Date;

(G) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the close of business on the Business Day immediately preceding the Purchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have all or a portion of such Note purchased;

(H) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by Holders thereof exceeds the Offer Amount, the Notes and other pari passu Indebtedness will be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess of $2,000, will be purchased); and

(I) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess of $2,000.

(4) On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 4.12. The Company, the Depositary or the Paying Agent, as the case may be, will promptly mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company or its agent to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Section 4.13. Limitation on Transactions with Affiliates. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”), involving aggregate consideration payable to or by the Company or a Restricted Subsidiary in excess of $1 million, unless:

(1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company; and

(2) the Company delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $15 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by at least a majority of the disinterested members of the Board of Directors of the Company; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued by an accounting, appraisal or investment banking firm, or other independent entity with appropriate expertise, of national standing.

(b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of paragraph (a):

(1) any employment, consulting, severance, termination or similar agreement or arrangement, stock option or stock ownership plan, employee benefit plan, officer or director compensation or indemnification agreement, restricted stock agreement, severance agreement or other compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments, awards, grants or issuances of securities pursuant thereto;

(2) transactions between or among the Company and/or its Restricted Subsidiaries, the issuance of Guarantees for the benefit of the Company or a Restricted Subsidiary and pledges of Equity Interests of Unrestricted Subsidiaries for the benefit of lenders to Unrestricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Subsidiary, an Equity Interest in, or controls, such Person;

(4) fees and expenses and compensation paid to, and indemnification or insurance provided on behalf of, officers, directors or employees of the Company or any of its Restricted Subsidiaries;

(5) any issuance of Equity Interests (other than Disqualified Stock) of the Company to, or receipt of a capital contribution from, Affiliates of the Company;

(6) Restricted Payments that do not violate Section 4.07;

(7) loans or advances to employees in the ordinary course of business or consistent with past practice;

(8) advances to or reimbursements of employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the ordinary course of business;

(9) the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any written agreement to which the Company or any of its Restricted Subsidiaries was a party on the Issue Date, as these agreements may be amended, modified or supplemented from time to time; provided, however, that any future amendment, modification or supplement entered into after the Issue Date will be permitted to the extent that its terms do not materially and adversely affect the rights of any Holders of the Notes (as determined in good faith by the Board of Directors of the Company) as compared to the terms of the agreements in effect on the Issue Date;

(10) transactions between the Company or any Restricted Subsidiary and any Person, a director of which is also a director of the Company or any direct or indirect parent company of the Company and such director is the sole cause for such Person to be deemed an Affiliate of the Company or any Restricted Subsidiary; provided, however, that such director abstains from voting as director of the Company or such direct or indirect parent company of the Company, as the case may be, on any matter involving such other Person; and

(11) in the case of (i) 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 (ii) 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 Company or any Restricted Subsidiary and third parties or, if neither the Company nor any Restricted Subsidiary has entered into a similar contract with a third party, that the terms are no less favorable than those available from third parties on an arm’s-length basis, as determined by at least a majority of the disinterested members of the Board of Directors or the Company (or, if there is only one disinterested member, such disinterested member).

Section 4.14. Designation of Restricted and Unrestricted Subsidiaries. (a) The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation. That designation will only be permitted if the applicable Restricted Subsidiary meets the definition of an Unrestricted Subsidiary and if such Investment would be permitted at that time, either pursuant to Section 4.07 or the definition of Permitted Investment.

(b) Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors of the Company giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07, provided that such covenant need not be complied with if the Subsidiary to be so designated has total assets of $1,000 or less. If, at any time, any Unrestricted Subsidiary would fail to meet the requirements of the definition of “Unrestricted Subsidiary,” it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.06, the Company will be in Default of Section 4.06.

(c) The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.06, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.

Section 4.15. Reports. (a) Regardless of whether required by the rules and regulations of the Commission, so long as any Notes are outstanding, the Company will file with the Commission for public availability, within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept such a filing, in which case the Company will comply with the requirements described in paragraph (b) below):

(1) all quarterly and annual reports that would be required to be filed with the Commission on Forms 10-Q and 10-K if the Company were required to file such reports; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will include a report on the Company’s consolidated financial statements by the Company’s certified independent accountants.

(b) If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company will nevertheless continue filing the reports specified in the clauses (1) and (2) of paragraph (a) with the Commission within the time periods specified above unless the Commission will not accept such a filing. The Company will not take any action for the purpose of causing the Commission not to accept any such filings. If, notwithstanding the foregoing, the Commission will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraphs on its website within the time periods that would apply if the Company were required to file those reports with the Commission and deliver a copy of the reports to the Trustee.

(c) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by paragraphs (a) and (b) will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

(d) The Company agrees that, for so long as any Notes remain outstanding, but only until completion of the Exchange Offer, if at any time it is not required to file with the Commission the reports required by the paragraphs (a) and (b), it will furnish to the Holders of Notes and to securities analysts and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(e) If any direct or indirect parent company of the Company provides a full and unconditional guarantee of the Notes, the Company may satisfy its Obligations in this covenant with respect to financial information relating to the Company by furnishing financial information relating to such parent company; provided that the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such parent, on the one hand, and the information relating to the Company and its Subsidiaries on a standalone basis, on the other hand.

(f) All obligors on the Notes will comply with Section 314(a) of the Trust Indenture Act.

(g) Delivery of these reports and information to the Trustee is for informational purposes only and the Trustee’s receipt of them will 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 4.16. Reports to Trustee. (a) The Company will deliver to the Trustee within 120 days after the end of each fiscal year a certificate from the Chief Executive Officer or the Chief Financial Officer of the Company stating that the officer has conducted or supervised a review of the activities of the Company and its Restricted Subsidiaries and their performance under this Indenture and that, based upon such review, the Company has fulfilled its obligations hereunder or, if there has been a Default, specifying the Default and its nature and status.

(b) The Company will deliver to the Trustee, as soon as possible and in any event within five Business Days after the Company becomes aware of the occurrence of a Default or Event of Default, an Officers’ Certificate setting forth the details of the Default or Event of Default, and the action which the Company proposes to take with respect thereto.

(c) The Company will notify the Trustee in writing when any Notes are listed on any national securities exchange and of any delisting.

Section 4.17. Covenant Termination. From and after the occurrence of an Investment Grade Rating Event, the Company and its Restricted Subsidiaries shall no longer be subject to Sections 4.06, 4.07, 4.09, 4.12, 4.13 and Section 5.01(a)(D) of this Indenture. Furthermore, after an Investment Grade Rating Event, the Company may not designate any of its Subsidiaries as Unrestricted Subsidiaries. However, the Company and its Restricted Subsidiaries will remain subject to all other covenants in this Indenture, including those described above under Section 4.08, Section 4.10 and Section 4.11. The Company shall notify the Trustee and the Holders of the Notes in writing of the occurrence of any Investment Grade Rating Event within 30 days following the occurrence of that event.

ARTICLE 5

CONSOLIDATION, MERGER OR SALE OF ASSETS

Section 5.01. Merger, Consolidation or Sale of Substantially All Assets. (a) The Company will not (1) consolidate or merge with or into another Person (regardless of whether the Company is the surviving corporation), convert into another form of entity or continue in another jurisdiction; or (2) directly or indirectly, sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless:

(A) either: (i) the Company is the surviving corporation; or (ii) the Person formed by or surviving any such consolidation or merger or resulting from such conversion (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

(B) the Person formed by or surviving any such conversion, consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made assumes all the obligations of the Company under the Notes and this Indenture (and the Registration Rights Agreement, if any obligations thereunder remain unsatisfied) pursuant to a supplemental indenture; provided that, unless such Person is a corporation, a corporate co-issuer of the Notes will be added to this Indenture by a supplement reasonably satisfactory to the Trustee;

(D) the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company), or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made, would (on the date of such transaction after giving pro forma effect thereto and to any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period) either:

(i) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.06(a); or

(ii) have a Fixed Charge Coverage Ratio that is not less than the Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries immediately before such transaction; and

(E) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, sale, transfer or lease and such supplemental indenture, if any, comply with this Section and that all conditions precedent herein provided for relating to such transaction have been complied with.

(c) Notwithstanding the restrictions described in clause (D) of paragraph (a), any Restricted Subsidiary may consolidate with, merge into or dispose of all or part of its properties or assets to the Company, the Company may merge into a Restricted Subsidiary for the purpose of reincorporating the Company in another jurisdiction, and any Restricted Subsidiary may consolidate with, merge into or dispose of all or part of its properties or assets to another Restricted Subsidiary.

(d) Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of the Company in a transaction that is subject to, and that complies with the provisions of, this Section, the successor Person formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for the Company (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein and the predecessor Company shall be discharged and released from all Obligations under this Indenture and the Notes; provided, however, that the predecessor Company shall not be released from the obligation to pay the principal of and interest on the Notes in the case of a lease of all or substantially all of the Company’s properties or assets in a transaction that is subject to, and that complies with the provisions of this Section.

Section 5.02. Merger, Consolidation or Disposition of Substantially all Assets of Subsidiary Guarantor. A Subsidiary Guarantor may not sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with or into (regardless of whether such Subsidiary Guarantor is the surviving Person), another Person, other than the Company or another Subsidiary Guarantor, unless:

(1) immediately after giving effect to that transaction, no Default or Event of Default exists; and

(2) either:

(a) (i) such Subsidiary Guarantor is the surviving Person or (ii) the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor under this Indenture (including its Subsidiary Guarantee) pursuant to a supplemental indenture satisfactory to the Trustee; or

(b) such transaction does not as of the date thereof violate Section 4.12.

ARTICLE 6

DEFAULT AND REMEDIES

Section 6.01. Events of Default. Each of the following is an “Event of Default” with respect to the Notes:

(1) a default in the payment when due of principal of, or premium, if any, on the Notes;

(2) a default for 30 days in the payment when due of interest on the Notes;

(3) failure by the Company to comply with its obligations under Section 5.01 or to consummate a purchase of Notes when required pursuant to Sections 4.11 or 4.12.

(4) failure by the Company or any of its Restricted Subsidiaries for 30 days (or 120 days with respect to Section 4.15) after written notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes to comply with Sections 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 or 4.15 to the extent not described in clause (3) above;

(5) failure by the Company or any of its Restricted Subsidiaries for 60 days after written notice from the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes to comply with any of the other agreements in this Indenture or the Notes;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is Guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the Company or any of its Restricted Subsidiaries, whether such Indebtedness or Guarantee now exists, or is created after the Issue Date, which default:

(A) is caused by a failure to pay principal of or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (“Payment Default”); or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity;

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20 million or more;

(7) failure by the Company or any Significant Subsidiary or group of the Company’s Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $20 million (net of any amounts covered by insurance), which judgments are not paid, discharged or stayed for a period of 60 days;

(8) except as permitted by this Indenture, any Subsidiary Guarantee is held in a judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee;

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

(A) commences a voluntary case;

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

(D) generally is not paying its debts as they become due; and

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

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

(B) appoints a custodian of the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, or for all or substantially all of the property of the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary; or

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

and, in each case, the order or decree remains unstayed and in effect for 60 consecutive days.

Section 6.02. Acceleration. (a) In the case of an Event of Default specified in clause (9) or clause (10) of Section 6.01(a), all then 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 aggregate principal amount of the then outstanding Notes may declare all of the Notes to be due and payable immediately by notice in writing to the Company and, in case of a notice by Holders, also to the Trustee specifying the respective Event of Default and that it is a notice of acceleration. Upon any such declaration, the Notes shall become due and payable immediately.

(b) At any time after such a declaration of acceleration with respect to the Notes has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in Article 6 provided, the Holders of at least a majority in principal amount of the then outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(1) the Company or one or more of the Subsidiary Guarantors has paid or deposited with the Trustee a sum sufficient to pay:

(A) all overdue interest on all Notes;

(B) the principal of (and premium, if any, on) any Notes which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Notes;

(C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Notes; and

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and

(2) all Events of Default with respect to the Notes, other than the non-payment of the principal of the Notes that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.04.

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

(c) Notwithstanding paragraphs (a) or (b), if an Event of Default specified in clause (6) of paragraph (a) shall have occurred and be continuing, such Event of Default and any consequential acceleration (to the extent not in violation of any applicable law or in conflict with any judgment or decree of a court of competent jurisdiction) shall be automatically rescinded if (A) the Indebtedness that is the subject of such Event of Default has been repaid or (B) the default relating to such Indebtedness is waived by the holders of such Indebtedness or cured and if such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness.

Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal of and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding.

Section 6.04. Waiver of Past Defaults. Except as otherwise provided in Sections 6.02(b), 6.07 and 9.02(b), the Holders of at least a majority in principal amount of the outstanding Notes may, by notice to the Trustee, waive an existing Default and its consequences, except a continuing Default in the payment of principal, premium (if any) or interest on the Notes. Upon such waiver, the Default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, but no such waiver will extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05. Control by Majority. The Holders of at least a majority in aggregate principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders of Notes not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from Holders of Notes.

Section 6.06. Limitation on Suits. Except to enforce the right to receive payment of principal, premium, if any, or interest, when due, a Holder may not institute any proceeding, judicial or otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy under this Indenture or the Notes, unless:

(1) such Holder has previously given to the Trustee written notice of a continuing Event of Default;

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

(3) such Holders have offered the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

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

(5) Holders of at least a majority in aggregate principal amount of the outstanding Notes have not given the Trustee a direction that is inconsistent with such written request within such 60-day period.

Section 6.07. Rights of Holders to Receive Payment. Notwithstanding anything to the contrary, the right of a Holder of a Note to receive payment of principal of or interest on its Note on or after the Stated Maturity thereof, or to bring suit for the enforcement of any such payment on or after such respective dates, may not be impaired or affected without the consent of that Holder.

Section 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal or interest specified in clause (1) or (2) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust for the whole amount of principal and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent lawful, overdue installments of interest, in each case at the rate specified in the Notes, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee hereunder.

Section 6.09. Trustee May File Proofs of Claim. The Trustee may file 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 compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder) and the Holders allowed in any judicial proceedings relating to the Company or any Subsidiary Guarantor or their respective creditors or property, and is entitled and empowered to collect, receive and distribute any money, securities or other property payable or deliverable upon conversion or exchange of the Notes or upon any such claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, if the Trustee consents to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation, and reasonable expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee hereunder. Nothing in this Indenture will be deemed to empower 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 thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities. If the Trustee collects any money or property pursuant to this Article, it shall pay out the money or property in the following order:

First: to the Trustee for all amounts due hereunder;

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

Third: to the Company or as a court of competent jurisdiction may direct.

The Trustee, upon written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section.

Section 6.11. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted a proceeding to enforce any right or remedy under this Indenture and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the Holder, then, subject to any determination in the proceeding, the Company, any Subsidiary Guarantors, the Trustee and the Holders will be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Company, any Subsidiary Guarantors, the Trustee and the Holders will continue as though no such proceeding had been instituted.

Section 6.12. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant (other than the Trustee) 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 any suit by a Holder to enforce payment of principal of or interest on any Note on the respective due dates, or a suit instituted by the Company, the Trustee or any Holders of more than 10% in principal amount of the outstanding Notes.

Section 6.13. Rights and Remedies Cumulative. No right or remedy conferred or reserved to the Trustee or to the Holders under this Indenture is intended to be exclusive of any other right or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in addition to every other right and remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or exercise of any other right or remedy.

Section 6.14. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.15. Waiver of Stay, Extension or Usury Laws. The Company and each Subsidiary Guarantor covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company or the Subsidiary Guarantor from paying all or any portion of the principal of, or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture. The Company and each Subsidiary Guarantor hereby expressly waives, to the extent that it may lawfully do so, all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

THE TRUSTEE

Section 7.01. General. (a) The duties and responsibilities of the Trustee are as provided by the Trust Indenture Act and as set forth herein. Whether or not expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee is subject to this Article.

(b) Except during the continuance of an Event of Default, the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations will be read into this Indenture against the Trustee. In case an Event of Default has occurred and is continuing, the Trustee shall exercise those rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct.

Section 7.02. Certain Rights of Trustee. Subject to Trust Indenture Act Sections 315(a) through (d):

(1) In the absence of bad faith on its part, the Trustee may conclusively rely, and will be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but, in the case of any document which is specifically required to be furnished to the Trustee pursuant to any provision hereof, the Trustee shall examine the document to determine whether it conforms to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein). The Trustee, in its discretion, may make further inquiry or investigation into such facts or matters as it sees fit.

(2) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel conforming to Section 11.05 and the Trustee will not be liable for any action it takes or omits to take in good faith in reliance on the certificate or opinion.

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

(4) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders, unless such Holders have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(5) The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within its rights or powers or for any action it takes or omits to take in accordance with the direction of the Holders in accordance with Section 6.05 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture.

(6) The Trustee may consult with counsel, and the advice or opinion of such counsel or any Opinion of Counsel will be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(7) The Trustee will not be liable for any error of judgment made in good faith by a responsible officer of the Trustee unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts.

(8) The Trustee may refuse to perform any duty or exercise any right or power that would require it to expend its own funds or risk any liability if it reasonably believes that repayment of such funds or adequate indemnity against such risk is not reasonably assured to it.

(9) Anything in this Indenture to the contrary notwithstanding, in no event will the Trustee be liable under or in connection with this Indenture for indirect, special, incidental, punitive or consequential losses or damages of any kind whatsoever, including but not limited to lost profits, whether or not foreseeable, even if the Trustee has been advised of the possibility thereof and regardless of the form of action in which such damages are sought.

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

Section 7.03. Individual Rights of Trustee. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not the Trustee.

(a) “cash transaction” means any transaction in which full payment for goods or securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand; and

(b) “self-liquidating paper” means any draft, ▇▇▇▇ of exchange, acceptance or obligation which is made, drawn, negotiated or incurred for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship arising from the making, drawing, negotiating or incurring of the draft, ▇▇▇▇ of exchange, acceptance or obligation.

Section 7.05. Notice of Default.

Notice to Holders under this Section will be given in the manner and to the extent provided in Trust Indenture Act Section 313(c).

Section 7.06. Reports by Trustee to Holders. Within 60 days after each May 15, beginning with May 15, 2013, the Trustee will mail to each Holder, as provided in Trust Indenture Act Section 313(c), a brief report dated as of such May 15, if required by Trust Indenture Act Section 313(a), and file such reports with each stock exchange upon which the Notes are listed and with the Commission as required by Trust Indenture Act Section 313(d).

Section 7.07. Compensation and Indemnity. (a) The Company will pay the Trustee compensation as agreed upon in writing for its services. The compensation of the Trustee is not limited by any law on compensation of a Trustee of an express trust. The Company will reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Trustee, including the compensation and expenses of the Trustee’s agents and counsel.

(b) The Company will indemnify the Trustee for, and hold it harmless against, any loss or liability or expense incurred by it without negligence or bad faith on its part arising out of or in connection with the acceptance or administration of this Indenture and its duties under this Indenture and the Notes, including the costs and expenses of defending itself against any claim or liability and of complying with any process served upon it or any of its officers in connection with the exercise or performance of any of its powers or duties under this Indenture and the Notes.

Section 7.08. Replacement of Trustee. (a) (1) The Trustee may resign at any time by written notice to the Company.

(2) The Holders of at least a majority in principal amount of the outstanding Notes may remove the Trustee by written notice to the Trustee.

(3) If the Trustee is no longer eligible under Section 7.10 or in the circumstances described in Trust Indenture Act Section 310(b), any Holder that satisfies the requirements of Trust Indenture Act Section 310(b) may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(4) The Company may remove the Trustee if: (i) the Trustee is no longer eligible under Section 7.10; (ii) the Trustee is adjudged a bankrupt or an insolvent; (iii) a receiver or other public officer takes charge of the Trustee or its property; or (iv) the Trustee becomes incapable of acting. A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

(b) If the Trustee has been removed by the Holders, Holders of at least a majority in principal amount of the Notes may appoint a successor Trustee with the consent of the Company. Otherwise, if the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a successor Trustee. If the successor Trustee does not deliver its written acceptance within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least a majority in principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(c) Upon delivery by the successor Trustee of a written acceptance of its appointment to the retiring Trustee and to the Company, (i) the retiring Trustee will transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07, (ii) the resignation or removal of the retiring Trustee will become effective, and (iii) the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. Upon request of any successor Trustee, the Company will execute any and all instruments for fully vesting in and confirming to the successor Trustee all such rights, powers and trusts. The Company will give notice of any resignation and any removal of the Trustee and each appointment of a successor Trustee to all Holders, and include in the notice the name of the successor Trustee and the address of its Corporate Trust Office.

(d) Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 will continue for the benefit of the retiring Trustee.

(e) The Trustee agrees to give the notices provided for in, and otherwise comply with, Trust Indenture Act Section 310(b).

Section 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation or national banking association, the resulting, surviving or transferee corporation or national banking association without any further act will be the successor Trustee with the same effect as if the successor Trustee had been named as the Trustee in this Indenture.

Section 7.10. Eligibility. The Indenture must always have a Trustee that satisfies the requirements of Trust Indenture Act Section 310(a) and has a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition.

Section 7.11. Money Held in Trust. The Trustee will not be liable for interest on any money received by it except as it may agree with the Company.

ARTICLE 8

Section 8.02. Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect at any time to have either Section 8.03 or Section 8.04 be applied to all outstanding Notes upon compliance with the conditions set forth in the portions of this Article 8 relating Legal Defeasance and Covenant Defeasance.

Section 8.03. Legal Defeasance. (a) Upon the Company’s exercise under Section 8.02 of the option applicable to this Section 8.03, the Company and each of the Subsidiary Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.05 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including any Subsidiary Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Subsidiary Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including any Subsidiary Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.06 hereof and the other sections of this Indenture referred to in clauses (1) through (4) below, and to have satisfied all their other obligations under such Notes, the Subsidiary Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute instruments prepared by the Company acknowledging the same), except for the following provisions, which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on such Notes when such payments are due from the trust referred to in Section 8.06;

Upon the Company’s exercise under Section 8.02 of the option applicable to this Section 8.04, (i) the Company and each of the Subsidiary Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.05 hereof, be released from each of their obligations respecting the Notes under Sections 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15 and 5.01(a)(D) (such release and termination hereinafter referred to as “Covenant Defeasance”), (ii) the Events of Default described under Sections 6.01(a)(3) (other than with respect to Section 5.01), (a)(4), (a)(5), (a)(6), (a)(7), (a)(8) and Section 6.01(a)(9) and (a)(10) (but only with respect to Subsidiaries of the Company) in each case, will no longer constitute an Event of Default with respect to the Notes, and (iii) the Subsidiary Guarantees respecting such Notes will be released. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and the Subsidiary Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and the Notes will be unaffected thereby.

Section 8.05. Conditions to Legal Defeasance or Covenant Defeasance. In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.03 or Section 8.04:

(a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, nationally recognized appraisal film, or nationally recognized firm of independent public accountants to pay the principal of, or interest and premium, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;

(b) in the case of an election under Section 8.03, the Company must deliver to the Trustee an Opinion of Counsel stating that:

(1) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

(2) since the Issue Date, there has been a change in the applicable U.S. federal income tax law,

in either case stating that, and based thereon such Opinion of Counsel will state that, the Holders of the Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(c) in the case of an election under Section 8.04, the Company must deliver to the Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(d) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit or the grant of Liens securing such borrowing);

(e) such Legal Defeasance or Covenant Defeasance and the related deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(f) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others;

(g) the Company must deliver to the Trustee an Officers’ Certificate, stating that all conditions precedent set forth in clauses (a) through (f) have been complied with; and

(h) the Company must deliver to the Trustee an Opinion of Counsel, stating that all conditions precedent set forth in clauses (b), (c) and (e) have been complied with.

Section 8.06. Application of Trust Money. Subject to Section 8.07, the Trustee will hold in trust the cash in U.S. dollars or Government Securities deposited with it pursuant to Section 8.05, and apply the deposited money and the proceeds from deposited Government Securities to the payment of principal of and interest on the Notes in accordance with the Notes and this Indenture. Such money and Government Securities need not be segregated from other funds except to the extent required by law.

Section 8.07. Repayment to Company. Subject to Sections 7.07, 8.01 and 8.05, the Trustee will promptly pay to the Company upon request any excess money or Government Securities held by the Trustee at any time and thereupon be relieved from all liability with respect thereto. Subject to any applicable abandoned property laws, the Trustee will pay to the Company upon request any money held for payment with respect to the Notes that remains

unclaimed for two years, provided that before making such payment the Trustee may at the expense of the Company publish once in a newspaper of general circulation in New York City, or send to each Holder entitled to such money, notice that the money remains unclaimed and that after a date specified in the notice (at least 30 days after the date of the publication or notice) any remaining unclaimed balance of money will be repaid to the Company. After payment to the Company, Holders entitled to such money must look solely to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee with respect to such money will cease.

Section 8.08. Reinstatement. If and for so long as the Trustee is unable to apply any money or Government Securities held in trust pursuant to Section 8.01 or 8.05 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes will be reinstated as though no such deposit in trust had been made. If the Company makes any payment of principal of or interest on any Notes because of the reinstatement of its obligations, it will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held in trust.

ARTICLE 9

(3) reduce the rate of or change the time for payment of interest on any Note;

(4) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except non-payment of principal, premium, if any, or interest on the Notes that became due solely because of the acceleration of the Notes, which acceleration has been rescinded) or a Default or Event of Default in respect of a provision that cannot be amended or supplemented without the consent of each Holder affected;

(5) make any Note payable in a currency other than that stated in the Securities;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or premium, if any, or interest on the Notes (except as permitted by clause (7) below);

(7) waive a redemption or repurchase payment with respect to any Security (other than a payment required by Sections 4.11 or 4.12);

(8) modify any Subsidiary Guarantee in any manner adverse to the Holders of the Notes or release any Subsidiary Guarantor from its obligations under its Subsidiary Guarantee except in accordance with the terms of this Indenture;

(9) make any change in the ranking of the Notes or the Subsidiary Guarantees in a manner adverse to the Holders of the Notes or the Subsidiary Guarantees; or

(10) make any change in the preceding amendment, supplement and waiver provisions of this Indenture.

(c) It is not necessary for Noteholders to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

(d) An amendment, supplement or waiver under this Section will become effective on receipt by the Trustee of written consents (or, with respect to a tender or exchange offer for Notes in global form, electronic consents given in accordance with applicable procedures of the Depositary) from the Holders of the requisite percentage in principal amount of the outstanding Notes. After an amendment, supplement or waiver under this Section becomes effective, the Company will deliver electronically to the Depositary or mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

Section 9.03. Effect of Consent. (a) After an amendment, supplement or waiver becomes effective, it will bind every Holder unless it is of the type requiring the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting Holder.

(b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of the changed terms on the Note and return it to the Holder, or exchange it for a new Note that reflects the changed terms. The Trustee may also place an appropriate notation on any Note thereafter authenticated. However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion.

Section 9.04. Trustee’s Rights and Obligations. The Trustee is entitled to receive, and will be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted by this Indenture. If the Trustee has received such an Opinion of Counsel and an Officers’ Certificate, it shall sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver that affects the Trustee’s own rights, duties or immunities under this Indenture.

Section 9.05. Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

ARTICLE 10

GUARANTEES

Section 10.01. The Subsidiary Guarantees. Subject to this Article 10, each of the Subsidiary Guarantors hereby, jointly and severally, unconditionally guarantees 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:

(1) the principal of, premium, if any, on, and interest, if any, 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, premium on, if any, and interest, if any, on, the Notes, if lawful, 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

(2) 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 Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

Section 10.02. Execution and Delivery of Notation of Guarantee. To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Subsidiary Guarantor as of the date of this Indenture hereby agrees that a Notation of Guarantee substantially in the form attached as Exhibit H hereto will be endorsed by an Officer of such Subsidiary Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Subsidiary Guarantor by one of its Officers.

Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a Notation of Guarantee.

If an Officer whose signature is on this Indenture or on the Notation of Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Notation of Guarantee is endorsed, the Notation of Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Notation of Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors.

Section 10.03. Subsidiary Guarantee Unconditional. The obligations of each Subsidiary Guarantor hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released, discharged or otherwise affected by

(1) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company under this Indenture or any Note, by operation of law or otherwise;

(2) any modification or amendment of or supplement to this Indenture or any Note;

(3) any change in the corporate existence, structure or ownership of the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company or its assets or any resulting release or discharge of any obligation of the Company contained in this Indenture or any Note;

(4) the existence of any claim, set-off or other rights which the Subsidiary Guarantor may have at any time against the Company, the Trustee or any other Person, whether in connection with this Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

(5) any invalidity or unenforceability relating to or against the Company for any reason of this Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Company of the principal of or interest on any Note or any other amount payable by the Company under this Indenture; or

(6) any other act or omission to act or delay of any kind by the Company, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Subsidiary Guarantor’s obligations hereunder other than payment in full of the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Company under this Indenture.

Section 10.04. Discharge; Reinstatement. Subject to Section 10.09, each Subsidiary Guarantor’s obligations hereunder will remain in full force and effect until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Company under this Indenture have been paid in full. If at any time any payment of the principal of, premium, if any, or interest on any Note or any other amount payable by the Company under this Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Subsidiary Guarantor’s obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

Section 10.05. Waiver by the Subsidiary Guarantors. Each Subsidiary Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person.

Section 10.06. Subrogation and Contribution. Upon making any payment with respect to any obligation of the Company under this Article, the Subsidiary Guarantor making such payment will be subrogated to the rights of the payee against the Company with respect to such obligation, provided that the Subsidiary Guarantor may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any other Subsidiary Guarantor, with respect to such payment so long as any amount payable by the Company hereunder or under the Notes remains unpaid.

Section 10.07. Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Company under this Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of this Indenture are nonetheless payable by the Subsidiary Guarantors hereunder forthwith on demand by the Trustee or the Holders.

Section 10.08. Limitation on Amount of Subsidiary Guarantee. Notwithstanding anything to the contrary in this Article, each Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Subsidiary Guarantor not constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each Subsidiary Guarantor under its Subsidiary Guarantee are limited to the maximum amount that would not render the Subsidiary Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

Section 10.09. Release of Subsidiary Guarantee. The Subsidiary Guarantee of a Subsidiary Guarantor will terminate:

(1) upon any sale or other disposition of all or substantially all of the properties or assets of such Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate as of the date thereof Section 4.12;

(2) upon any sale or other disposition of the Capital Stock of such Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition does not violate as of the date thereof Section 4.12 and such Subsidiary Guarantor no longer qualifies as a Subsidiary of the Company as a result of such disposition;

(3) upon designation of such Subsidiary Guarantor as an Unrestricted Subsidiary, in accordance with Section 4.14;

(4) upon Legal Defeasance, Covenant Defeasance or satisfaction and discharge of this Indenture as provided pursuant to Sections 8.01, 8.02, 8.03 and 8.04;

(5) upon the liquidation or dissolution of such Subsidiary Guarantor, provided no Default or Event of Default occurs as a result thereof or has occurred or is continuing; or

(6) unless a Default or Event of Default has occurred and is continuing, if such Subsidiary Guarantor ceases to Guarantee any Indebtedness of the Company or a Guarantor under a Credit Facility.

Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the foregoing effect, the Trustee will execute documents reasonably required in order to evidence the release of the Subsidiary Guarantor from its obligations under its Subsidiary Guarantee.
