RECITATIONS OF THE COMPANY

WHEREAS, the Company, the Guarantors and the Trustee have heretofore executed and delivered the Original Indenture to provide for the issuance of the Company’s subordinated debt securities to be issued in one or more series;

WHEREAS, Section 901 of the Original Indenture provides, among other things, that the Company, the Guarantors and the Trustee may without the consent of Holders enter into indentures supplemental to the Original Indenture to, among other things, (a) add to, change or eliminate any of the provisions of the Original Indenture in respect of one or more series of Securities, provided that any such addition, change or elimination (i) shall neither (A) apply to any Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (B) modify the rights of the Holder of any such Security with respect to such provision or (ii) shall become effective only when there is no such Security Outstanding and (b) establish the form or terms of Securities of any series as permitted by Sections 201 and 301 of the Original Indenture;

WHEREAS, the Company desires to provide for the issuance of a series of Securities to be designated as the “6¹⁄₂% Senior Subordinated Mandatory Convertible Notes due 2018, Series A-1” (the “Notes”), and to set forth the form and terms thereof;

WHEREAS, the Company proposes in and by this Second Supplemental Indenture to supplement and amend the Original Indenture, but only insofar as it will apply to the Notes; and

WHEREAS, all action on the part of the Company necessary to authorize the creation and issuance of the Notes, and all action on the part of each of the Guarantors necessary to authorize its guarantee of the Notes under the Original Indenture and this Second Supplemental Indenture (the Original Indenture, as supplemented and amended by this Second Supplemental Indenture, being hereinafter called the “Indenture”), have been duly taken.

NOW, THEREFORE, THIS SECOND SUPPLEMENTAL INDENTURE WITNESSETH:

That, in order to establish the designation, form and terms of, and to authorize the authentication and delivery of the Notes, and in consideration of the acceptance of the Notes by the Holders thereof and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE 1

DEFINITIONS AND INCORPORATION

BY REFERENCE

Section 1.01. Definitions.

(a) Capitalized terms used herein and not otherwise defined shall have the respective meanings assigned thereto in the Original Indenture.

(b) Section 101 of the Original Indenture is amended and supplemented, with respect to the Notes, by inserting or restating, as the case may be, in their appropriate alphabetical position, the following definitions:

“ACNTA” means (without duplication), as of the date of determination:

(1) the sum of:

(a) discounted future net revenue from proved crude oil and natural gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with SEC 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 to reserves accounting for at least 80% of all such discounted future net revenue and by the Company’s petroleum engineers with respect to any other reserves covered by such report, as increased by, as of the date of determination, the discounted future net revenue from:

(i) 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

(ii) estimated 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 each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year-end reserve report), and decreased by, as of the date of determination, the discounted future net revenue attributable to

(iii) 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 and

(iv) 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 SEC guidelines (utilizing the prices utilized in such year-end reserve report); provided, however, that, in the case of each of the determinations made pursuant to clauses (i) through (iv), such increases and decreases shall be as estimated by the Company’s engineers, except that if as a result of such acquisitions, dispositions, discoveries, extensions or revisions, there is a Material Change, then such increases and decreases in the discounted future net revenue shall be confirmed in writing by an independent petroleum engineer;

(b) 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;

(c) the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial statements; and

(d) the greater of (I) the net book value on a date no earlier than the date of the Company’s latest annual or quarterly financial statements and (II) the appraised value, as estimated by independent appraisers, of other tangible assets of the Company and its Restricted Subsidiaries as of a date no earlier than the date of the Company’s latest audited financial statements;

(2) minus, to the extent not otherwise taken into account in the immediately preceding clause (1), the sum of:

(a) minority interests;

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

(c) the discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the same prices utilized in the Company’s year-end reserve report), attributable to reserves subject to participation interests, overriding royalty 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;

(d) the discounted future net revenue, calculated in accordance with SEC guidelines (utilizing the same prices utilized in the Company’s year-end reserve report), 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

(e) the discounted future net revenue, calculated in accordance with SEC guidelines, 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 (1)(a) (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.

If the Company changes its method of accounting for its oil and gas properties from the successful efforts method to the full cost method or a similar method of accounting, ACNTA will continue to be calculated as if the Company were still using the successful efforts method of accounting.

ARTICLE 2

THE NOTES

Section 2.01. Creation and Form.

Pursuant to Sections 201 and 301 of the Original Indenture, there is hereby created a new series of Securities designated as the “6¹⁄₂% Senior Subordinated Mandatory Convertible Notes due 2018, Series A-1” (which are herein referred to as the “Notes” for purposes of this Second Supplemental Indenture). The Notes shall be substantially in the form specified in Exhibit A to this Second Supplemental Indenture, shall have the terms set forth therein and shall be entitled to the benefits of the other provisions of the Original Indenture as modified by this Second Supplemental Indenture and specified herein. To the extent permitted by applicable law, in the event of any inconsistency between the terms of the Notes and the terms of this Indenture, the terms of this Indenture will control. To the extent applicable, the Initial Notes and Additional Notes will bear the OID Legend. Each certificate representing shares of Common Stock issued upon conversion of any Note, shall, upon issuance, if such shares are subject to restriction on transfer under the Securities Act at their time of issuance, bear the Common Stock Restricted Legend on the face thereof until the Resale Restriction Termination Date.

Section 2.02. Execution and Authentication.

On the Issue Date, the Trustee shall authenticate and deliver $26,167,000 Original Principal Amount of Initial Notes and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Additional Notes for original issue, in each case upon the Trustee’s receipt of a Company Order in accordance with Section 303 of the Original Indenture. Such order shall specify the aggregate Original Principal Amount of the Notes to be authenticated and the date on which the original issue of Notes is to be authenticated and, in the case of an issuance of Additional Notes pursuant to Section 2.05 of this Second Supplemental Indenture after the Issue Date, shall certify that such issuance is in compliance with such Section 2.05 and Section 4.09 hereof. The Notes shall be issued initially in the form of Global Securities, for which The Depository Trust Company shall act as Depositary. Notes in the form of Global Securities shall bear the legends set forth on the form of Note attached hereto.

Section 2.03. Outstanding Notes.

Notes outstanding at any time are all Notes authenticated by the Trustee except for those that have been converted, those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. Except as otherwise provided in TIA §316(a), a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

If a Note is replaced pursuant to Section 306 of the Original Indenture, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser.

If the Paying Agent segregates and holds in trust, in accordance with the Indenture, by 11:00 a.m. New York time, on a Redemption Date or other maturity date money sufficient to pay all Reduced Principal Amount, premium, if any, and interest payable on that date with respect to

the Notes (or portions thereof) to be redeemed or otherwise maturing, as the case may be, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

Section 2.04. CUSIP Numbers.

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

Section 2.05. Issuance of Additional Notes.

The Company shall be entitled, subject to its compliance with Section 4.09 of this Second Supplemental Indenture, to issue Additional Notes under the Indenture which shall have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance, issue price, the initial date from which interest begins to accrue, if applicable, the existence of resale restrictions pursuant to the Securities Act, and, in the event that Additional Notes are issued after the end of the Reduction Observation Period, other than differences with respect to Reduction, provided, that no Additional Notes may be issued with the same “CUSIP”, “ISIN” or “Common Code” number as the Initial Notes unless it is so permitted in accordance with applicable law and such Additional Notes are fungible with the Initial Notes for U.S. federal tax purposes. The Initial Notes issued on the Issue Date and any Additional Notes shall be treated as a single class for all purposes under the Indenture.

Indenture, the Conversion Rate and Conversion Price in effect on the date of the notice of redemption and that a Holder who elects to convert all or a portion of its Notes in lieu of redemption must submit a Conversion Notice with respect to such Notes being converted on or before the close of business on the Business Day immediately preceding the Redemption Date.

Section 3.03. Mandatory Redemption.

Except as set forth under Sections 4.10 and 4.15 hereof, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders.

Section 3.04. Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Company shall be required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it shall follow the procedures specified below.

The Asset Sale Offer shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by Applicable Law (the “Offer Period”).

Payment for any Notes so purchased shall be made in the manner prescribed in the Notes.

(g) that Holders shall be entitled to withdraw their election if the Company or the Paying Agent, as the case may be, receives, prior to the Termination Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the Original Principal Amount and Reduced Principal Amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(h) that, if the aggregate Reduced Principal Amount of Notes surrendered by Holders, and Pari Passu Indebtedness surrendered by holders or lenders, collectively, exceeds the amount the Company is required to repurchase, the Trustee shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate Reduced Principal Amount of tendered Notes and Pari Passu Indebtedness (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of Original Principal Amount equal to $1,000 or any integral $1,000 multiple in excess thereof, shall be purchased);

(i) that Holders whose Notes were purchased only in part shall be issued new Notes equal in Original Principal Amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer); and

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

Promptly after the Termination Date, the Company shall, to the extent lawful, accept for payment Notes or portions thereof tendered pursuant to the Asset Sale Offer in the aggregate Reduced Principal Amount required by Section 4.10 hereof, and prior to the Settlement Date it shall deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.04 and Section 4.10 hereof. On the Settlement Date, the Company or the Paying Agent, as the case may be, shall 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 shall issue a new Note, and the Trustee shall authenticate and mail or deliver such new Note to

such Holder, in an Original 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 to the Holder thereof.

(c) The principal amount payable per $1,000 Original Principal Amount of Notes shall be reduced (each, a “Reduction”) by $40 (the “Reduced Principal”) for each VWAP Trading Day during the Reduction Observation Period, if the Daily VWAP exceeds the Threshold Price on such VWAP Trading Day. Reductions shall be subject to Section 11.01(d) and to all other provisions of Article 11 that are expressly applicable to Reductions.

(d) On the third Business Day (or, in the event that the Company with commercially reasonable efforts cannot effect settlement on such third Business Day, then the fifth Business Day) immediately following each VWAP Trading Day during the Reduction Observation Period, if the Daily VWAP exceeds the Threshold Price on such VWAP Trading Day (any such date of payment, a “Reduction Settlement Date”), the Company shall make a stock distribution to Holders of an amount of shares of Common Stock for each $40 of Reduced Principal per $1,000 Original Principal Amount of Notes equal to the Daily Reduction Rate on such VWAP Trading Day (plus cash in lieu of any fractional share of Common Stock issuable

(j) Notwithstanding anything to the contrary herein or in the Notes, in the event that any settlement of Common Stock, cash in lieu of fractional shares or accrued but unpaid interest in respect of any Reduction Settlement Date cannot be made within the express time frames set forth in this Section 4.01 as a result of the settlement procedures and mechanics of the Depositary, any delay in settlement of such amounts shall not be a Default or Event of Default hereunder, provided that the Company is using its commercially reasonable efforts to effect such settlement as soon as practicable. In the event that in connection with any settlement on any Reduction Settlement Date, the Company, the Trustee or the Depositary requires any notice or form from the beneficial holders of Notes in order to effect such settlement, then the settlement of Common Stock, cash in lieu of fractional shares or accrued but unpaid interest due on such Reduction Settlement Date shall be conditioned on delivery to the Company by such beneficial holders of such notice or form in the form requested by the Company, and the Company’s obligation to deliver the Common Stock, cash in lieu of fractional shares or accrued but unpaid interest due on such Reduction Settlement Date to any beneficial holder shall be no later than the third Business Day (or, in the event that the Company with commercially reasonable efforts cannot effect settlement on such third Business Day, then the fifth Business Day) after the date on which such beneficial holder of the Notes has delivered to the Company the notice or form requested by the Company. Until the Company provides notice to Holders to the contrary, the Company shall require beneficial holders of Notes to deliver the Reduction Settlement Notice (or a notice in such other form or format as the Company may accept in its sole discretion) no later than the close of business on the second Business Day immediately following the applicable Reduction Date (or any later date as the Company may accept in its sole discretion). In the event that the Depositary is unable to deliver cash in lieu of fractional shares or accrued but unpaid interest to its participants in accordance with this Section 4.01 through its systems on any Reduction Settlement Date or settlement of cash amounts on each Reduction Settlement Date is otherwise impracticable, then the Company may delay payment of all cash in lieu of fractional shares and accrued but unpaid interest in respect of all Reduced Principal until the Reduction Settlement Date in respect of the last day of the Reduction Observation Period.

Section 4.02. Maintenance of Office or Agency.

The Company shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee) where Notes may be presented or surrendered for payment or conversion and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. Further, if at any time there shall be no such office or agency in the City of New York where the 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 shall at all times be payable in the City of New York. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby appoints the Trustee as Paying Agent and Conversion Agent and designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 301 of the Original Indenture.

Section 4.03. Reports.

(a) Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, so long as any Notes are outstanding, the Company will file with the SEC (unless the SEC will not accept such a filing) for public availability within the time periods specified in the SEC’s rules and regulations under the Exchange Act and, within 10 Business Days of filing, or attempting to file, the same with the SEC, furnish to the Trustee and, upon its request, to any of the Holders of the Notes:

(1) all quarterly and annual financial and other information with respect to the Company and its Subsidiaries that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants; and

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

The Company’s filing of any such information, document or report with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval (or ▇▇▇▇▇) system or any successor thereto shall satisfy the reporting obligation described above.

The Company shall at all times comply with TIA § 314(a).

(b) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by paragraph (a) of this Section 4.03 shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes to the financial statements and in Management’s Discussion and Analysis of 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.

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

Section 4.04. Compliance Certificate.

(a) The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under the Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in the Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of the Indenture (or, if a Default or Event of Default with respect to the Notes shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments of interest on the Notes are prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto.

(b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware of any Default or Event of Default with respect to the Notes, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

Section 4.05. Taxes.

The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

Section 4.06. Stay, Extension and Usury Laws.

Each of the Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of the Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.07. Limitation on Restricted Payments.

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 or payable to the Company or a Restricted Subsidiary of the Company);

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

(3) make any principal payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the Notes or the Subsidiary Guarantees prior to any scheduled repayment or scheduled maturity, except a payment, purchase, redemption, defeasance or other acquisition of any such Indebtedness in anticipation of satisfying a sinking fund obligation, principal installment or the Stated Maturity thereof, in each case, due within one year of the date of such payment, purchase, redemption, defeasance or other acquisition; or

(4) make any Restricted Investment (all such payments and other actions set forth in these 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:

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

(2) 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 applicable 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 the first paragraph of Section 4.09; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after May 11, 2004 (excluding Restricted Payments permitted by clauses (2), (3), (4), (6) and (7) of the next succeeding paragraph), is 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 April 1, 2004 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 the aggregate net cash proceeds received by the Company (including the fair market value of any Additional Assets to the extent acquired in consideration of Equity Interests of the Company (other than Disqualified Stock)) since May 11, 2004 as a contribution to its 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), plus

(c) to the extent that any Restricted Investment that was made after May 11, 2004 is sold for cash or otherwise liquidated or repaid for cash, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment, plus

(d) to the extent that any Unrestricted Subsidiary of the Company is redesignated as a Restricted Subsidiary after May 11, 2004, the lesser of (i) the fair market value of the Company’s Investment in such Subsidiary as of the date of such redesignation or (ii) such fair market value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary.

The preceding provisions will not prohibit:

(1) the payment of any dividend or distribution or the consummation of any irrevocable redemption of debt that is subordinate to the Notes, within 60 days after the date of declaration of such dividend or the delivery of any irrevocable notice of redemption, as the case may be, if the dividend, distribution or redemption payment on the date of declaration or the date of the notice of redemption, as the case may be, would have complied with the provisions of the Indenture;

(2) the redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness of the Company or any Guarantor or of any Equity Interests of the Company in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock), with a sale being deemed substantially concurrent if such redemption, repurchase, retirement, defeasance or acquisition occurs not more than 120 days after such sale; provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition will be excluded from clause (3)(b) of the preceding paragraph;

(3) the defeasance, redemption, repurchase, retirement or other acquisition of subordinated Indebtedness of the Company or any Guarantor with the net cash proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness;

(4) the payment of any dividend or distribution by a Restricted Subsidiary of the Company to the holders of its Equity Interests on a pro rata basis;

(5) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any current or former director, officer, employee or consultant of the Company or any of its Restricted Subsidiaries pursuant to any equity subscription agreement or plan, stock option agreement or similar agreement or plan; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $2.0 million in any twelve-month period;

(6) the acquisition of Equity Interests by the Company in connection with the exercise of stock options or stock appreciation rights by way of cashless exercise;

(7) the payment of cash in lieu of fractional shares of Capital Stock in connection with any transaction otherwise permitted under this Section 4.07; or

(8) other Restricted Payments in an aggregate amount since May 11, 2004 not to exceed $25.0 million;

provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under the preceding clause (8), no Default or Event of Default shall have occurred and be continuing or would be caused thereby.

The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this covenant will be determined, in the case of amounts under $25.0 million, by an officer of the Company and, in the case of amounts over $50.0 million, by the Board of Directors of the Company, whose determination shall be evidenced by a Board Resolution. Not later than the date of making any Restricted Payment (excluding any Restricted Payment described in the preceding clause (2), (3), (4), (6) or (7)) the Company will deliver to the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 4.07 were computed. 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 categories of Restricted Payments described in the preceding clauses (1) through (8), or is entitled to be made pursuant to the first paragraph of this Section 4.07, the Company will be permitted to divide or classify (or later divided or classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 4.07.

Section 4.08. Limitation on Dividend and Other Payment Restrictions Affecting Subsidiaries.

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 or other obligations 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) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

However, the preceding restrictions of this Section 4.08 will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements governing Existing Indebtedness and Credit Facilities as in effect on the Original Issue Date and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements, provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the Original Issue Date as determined in good faith by the Company;

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

(3) Applicable Law;

(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, 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, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred, and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restricted, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of such acquisition as determined in good faith by the Company;

(5) customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices;

(6) Capital Lease Obligations or purchase money obligations, in each case for property acquired in the ordinary course of business that impose restrictions on that property of the nature described in clause (3) of the preceding paragraph;

(7) any agreement for the sale or other disposition of a Restricted Subsidiary of the Company that restricts distributions by that Restricted Subsidiary pending its sale or other disposition;

(8) Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced as determined in good faith by the Company;

(9) Liens securing Indebtedness otherwise permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;

(10) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements, agreements respecting Permitted Business Investments and other similar agreements entered into (a) in the ordinary course of business or (b) with the Company’s approval by its Board of Directors, which limitation is applicable only to property or capital stock that are subject to such agreements;

(11) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers or suppliers under contracts entered into in the ordinary course of business;

(12) restrictions on the sale, lease or transfer of property or assets arising or agreed to in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of property or assets of the Company or any Restricted Subsidiary in any manner material to the Company and the Restricted Subsidiaries taken as a whole; and

(13) Hedging Obligations permitted to be incurred under the covenants set forth in Section 4.09 hereof.

Section 4.09. Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock.

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”) any Indebtedness (including Acquired Debt), neither the Company nor any Guarantor will issue any Disqualified Stock, and the Company will not permit any of its other Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company and any Guarantor may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Fixed Charge Coverage Ratio for the Company’s 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 is issued would have been at least 2.0 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 Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period.

The first paragraph of this Section 4.09 will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(1) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness (including letters of credit) under one or more 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 Subsidiaries thereunder) not to exceed an amount equal to the greater of (a) $1.1 billion and (b) 30% of ACNTA as of the date of such incurrence;

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

(3) the incurrence by the Company and the Guarantors of Indebtedness represented by the Notes issued and sold on the Issue Date and the related Subsidiary Guarantees issued on the Issue Date;

(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 or improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary, in an aggregate principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of (a) $25.0 million and (b) 1.0% of ACNTA as of the date of such incurrence at any time outstanding;

(5) the incurrence 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 refund, refinance or replace Indebtedness (other than intercompany Indebtedness) that was permitted by the Indenture to be incurred under the first paragraph of this Section 4.09 or clause (2) or (3) of this paragraph 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 is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, or if

a Guarantor is the obligor on such Indebtedness and neither the Company nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Subsidiary Guarantee of such 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 of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company 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 incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations;

(8) the guarantee by the Company or any of the Guarantors of Indebtedness of the Company or any Guarantor that was permitted to be incurred by another provision of this Section 4.09;

(9) the incurrence by the Company or any of its Restricted Subsidiaries of obligations relating to net gas balancing positions arising in the ordinary course of business and consistent with past practice;

(10) the incurrence by the Company’s Unrestricted Subsidiaries of Non-Recourse Debt, provided, however, that if any such Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such event will be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that was not permitted by this clause (10);

(11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance, surety and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of the Company and any of its Restricted Subsidiaries with respect to letters of credit supporting such obligations (in each case other than an obligation for money borrowed);

(12) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Capital Stock of a Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries in connection with such disposition;

(13) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided, however, that such Indebtedness is promptly extinguished;

(14) Indebtedness arising in connection with endorsement of instruments for deposit in the ordinary course of business;

(15) Indebtedness owed on a short-term basis to banks and other financial institutions incurred in the ordinary course of business of the Company and any Restricted Subsidiary with such banks or financial institutions that arises in connection with ordinary banking arrangements to manage cash balances of the Company and any Restricted Subsidiary;

(16) the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with a transaction meeting either of the financial tests set forth in clause (4) under Section 5.01 hereof; and

(17) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, not to exceed $75.0 million.

For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (17) above, or is entitled to be incurred pursuant to the first paragraph of this Section 4.09, the Company will be permitted to divide and classify (or later divide, classify, re-divide or reclassify in whole or in part in its sole discretion) such item of Indebtedness in any manner that complies with this covenant, except that any indebtedness under Credit Facilities on the Original Issue Date (after giving effect to the offering of Existing Senior Subordinated Notes and the application of the proceeds thereof contemplated by the prospectus relating to such offering) shall be considered incurred under the first paragraph of this Section 4.09.

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, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of the Company as accrued. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed exceeded solely as a result of fluctuations in exchange rates or currency values.

Section 4.10. Limitation on Asset Sales.

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 the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of;

(2) the fair market value is determined by the Company’s Board of Directors and evidenced by a resolution of the Board of Directors set forth in an Officers’ Certificate delivered to the Trustee; and

(3) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash or Cash Equivalents:

(a) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet, of the Company or any Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by the transferee of any such assets pursuant to a novation agreement that releases the Company or such Subsidiary from further liability; and

(b) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Subsidiary into cash within 180 days of the receipt thereof, to the extent of the cash received in that conversion.

Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any such Restricted Subsidiary may apply those Net Proceeds at its option to any combination of the following:

(I) to prepay, repay, redeem or repurchase Senior Debt or the Notes or other Indebtedness ranking on parity with the Notes;

(II) to acquire all or substantially all of the properties or assets of one or more other Persons primarily engaged in the Oil and Gas Business, and, for this purpose, a division or line of business of a Person shall be treated as a separate Person;

(III) to acquire a majority of the Voting Stock of one or more other Persons primarily engaged in the Oil and Gas Business;

(IV) to make one or more capital expenditures; or

(V) to acquire other long-term assets that are used or useful in the Oil and Gas Business.

Pending the final application of any Net Proceeds, the Company or any such Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by the Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph will constitute “Excess Proceeds.”

On the 361st day after the Asset Sale (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $50.0 million, the Company will make an Asset Sale Offer to all Holders of Notes, and to all holders of Pari Passu Indebtedness then outstanding, to purchase the maximum Reduced Principal Amount of Notes and such 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 Reduced Principal Amount plus accrued and unpaid interest, if any, to the Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Settlement Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate Reduced Principal Amount of Notes and Pari Passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such Pari Passu Indebtedness to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of Original Principal Amount of $1,000 or any integral multiple of $1,000 in excess thereof, will be purchased). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

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 each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions by virtue of such conflict.

Section 4.11. Limitation on Transactions with Affiliates.

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 (each, an “Affiliate Transaction”) involving aggregate consideration in excess of $1.0 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 an unrelated Person or, if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view; 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 $30.0 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11 and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors; and

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, a written opinion as to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph of this Section 4.11:

(1) any employment, severance or consulting agreement or other compensation agreement, arrangement or plan, or any amendment thereto, entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business;

(2) transactions between or among any of the Company and its Restricted Subsidiaries;

(3) transactions with a Person that is an Affiliate of the Company solely because the Company owns an Equity Interest in such Person;

(4) payment of reasonable directors’ fees, consulting fees and other benefits to persons who are not otherwise Affiliates of the Company;

(5) provision of officers’ and directors’ indemnification and insurance in the ordinary course of business to the extent permitted by law;

(6) sales of Equity Interests (other than Disqualified Stock) to Affiliates of the Company;

(7) Permitted Investments and Restricted Payments that are permitted by Section 4.07 hereof;

(8) any transaction in which the Company or its Restricted Subsidiaries, as the case may be, deliver to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Company or its Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (1) of the initial paragraph above;

(9) transactions with Unrestricted Subsidiaries, Affiliates, customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of the Indenture which are, in the aggregate (taking into account all the costs and benefits

associated with such transactions) materially no less favorable to the Company or its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated person, in the good faith determination of the Company’s Board of Directors, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party; and

(10) transactions between the Company or any of its Restricted Subsidiaries and any Person, a director of which is also a director of the Company or any direct or indirect parent of the Company; provided, however, that such director abstains from voting as a director of the Company or such direct or indirect parent, as the case may be, on any matter involving such other Person.

Section 4.12. Limitation on Liens.

The Company will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness or Attributable Debt upon any of their property or assets, now owned or hereafter acquired, unless the Notes or any Subsidiary Guarantee of such Restricted Subsidiary, as applicable, is secured on an equal and ratable basis (or on a senior basis to, in the case of obligations subordinated in right of payment to the Notes or such Subsidiary Guarantee, as the case may be) with the obligations so secured until such time as such obligations are no longer secured by a Lien.

Section 4.13. Additional Subsidiary Guarantees.

If the Company or any of its Restricted Subsidiaries acquires or creates another Material Domestic Subsidiary after the Issue Date, or if any Restricted Subsidiary that is not already a Guarantor guarantees any other Indebtedness of the Company after such date, then in either case that Subsidiary will become a Guarantor by executing a supplemental indenture substantially in the form of Exhibit B hereto and delivering it to the Trustee within 20 Business Days of the date on which it was acquired or created or guaranteed Indebtedness of the Company, as the case may be, together with any Opinion of Counsel described in Section 903 of the Original Indenture; provided, however, that (a) the foregoing shall not apply to Subsidiaries of the Company that have properly been designated as Unrestricted Subsidiaries in accordance with the Indenture for so long as they continue to constitute Unrestricted Subsidiaries and (b) ▇▇▇▇▇▇▇ Programs, Inc. shall not be required to become a Guarantor unless it guarantees Indebtedness of the Company.

Section 4.14. Corporate Existence.

Except as otherwise permitted pursuant to the terms hereof (including consolidation and merger permitted by Section 5.01 hereof), the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary; provided, however, that the Company shall not be required to preserve the existence of any of its Restricted Subsidiaries if the Company shall

determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15. Offer to Repurchase Upon Change of Control.

(1) Within 30 days following the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $1,000 or any integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price (the “Change of Control Payment”) in cash equal to 101% of the aggregate Reduced Principal Amount of Notes repurchased, plus accrued and unpaid interest, if any, thereon to the date of settlement (the “Change of Control Settlement Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Settlement Date. Within 30 days following a Change of Control, the Company shall mail a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction that constitutes the Change of Control and stating:

(a) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes validly tendered and not withdrawn will be accepted for payment;

(b) the purchase price and the Change of Control Settlement Date, which shall be no earlier than 30 days but no later than 60 days from the date such notice is mailed;

(c) that the Change of Control Offer will expire as of the time specified in such notice on the Change of Control Settlement Date and that the Company shall pay the Change of Control Purchase Price for all Notes purchased as of the Change of Control Settlement Date promptly thereafter on the Change of Control Settlement Date;

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

(e) 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 shall cease to accrue interest after the Change of Control Settlement Date;

(f) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, properly endorsed for transfer, together with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes completed and such customary documents as the Company may reasonably request, to the Paying Agent at the address specified in the notice prior to the termination of the Change of Control Offer on the Change of Control Settlement Date;

(g) that Holders will be entitled to withdraw their election if the Paying Agent receives, prior to the termination of the Change of Control Offer, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the Reduced Principal Amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased;

(h) that Holders whose Notes are being purchased only in part will be issued new Notes equal in Original Principal Amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in Original Principal Amount or any integral multiple of $1,000 in excess thereof; and

(i) the Conversion Rate and Conversion Price then in effect and that a Holder that has tendered its Notes for purchase who wishes to withdraw such Notes and convert them must submit a valid notice of withdrawal and Conversion Notice prior to the close of business on the Business Day immediately preceding the Change of Control Settlement Date.

If any of the Notes subject to a Change of Control Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to repurchases. Further, the Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under such provisions by virtue of such conflict.

(2) On the Change of Control Settlement Date, the Company shall, to the extent lawful, accept for payment all Notes or portions thereof ($1,000 or any integral $1,000 multiple in excess thereof) properly tendered pursuant to the Change of Control Offer. Promptly thereafter on the Change of Control Settlement Date the Company shall:

(a) deposit with the Paying Agent by 11:00 a.m., New York City time, an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered; and

(b) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate Reduced Principal Amount of Notes or portions of Notes being purchased by the Company.

On the Change of Control Settlement Date, the Paying Agent shall mail 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 Depository) and the Trustee shall authenticate and mail (or cause to be transferred by

book entry) to each Holder a new Note equal in Original Principal Amount to any unpurchased portion of the Notes surrendered (with the Reduced Principal Amount also reflected on such Note), if any; provided, however, that each such new Note will be in an Original Principal Amount of $1,000 or any integral multiple of $1,000 in excess thereof. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date.

(c) The Change of Control provisions described above shall be applicable whether or nor any other provisions of the Indenture are applicable.

(d) Prior to complying with any of the provisions of this Section 4.15, but in any event no later than the Change of Control Settlement Date, the Company shall either repay all outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing outstanding Senior Debt to permit the repurchase of Notes required by this Section 4.15.

(e) The Company shall not be required to make a Change of Control Offer following a Change of Control (1) if a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption has been given pursuant to Section 3.02 hereof, unless and until there is a default in payment of the applicable Redemption Price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer by the Company or a third party may be made in advance of a Change of Control, and conditioned upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

(3) In the event that Holders of Notes of not less than 95% of the aggregate Reduced Principal Amount of the outstanding Notes accept a Change of Control Offer and the Company 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 the purchase pursuant to the Change of Control Offer, to redeem all of the Notes that remain outstanding following such purchase at a purchase price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain outstanding, if any, to the Change of Control Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Change of Control Settlement Date. Any such redemption shall be effected in accordance with Article Eleven of the Original Indenture; provided that any notice of redemption sent in respect of such redemption shall state, in addition to the requirements of Section 1104 of the Original Indenture, the Conversion Rate and Conversion Price in effect on the date of the notice of redemption and that a Holder who elects to convert all or a portion of its Notes in lieu of redemption must submit a Conversion Notice with respect to such Notes being converted on or before the close of business on the Business Day immediately preceding the Redemption Date.

Section 4.16. No Inducements.

The Company shall not, and the Company shall not permit any of its Subsidiaries, either directly or indirectly, to pay (or cause to be paid) any consideration, whether by way of interest, fee or otherwise, to any Beneficial Owner or Holder of the Notes for or as an inducement to any consent to any waiver, amendment or supplement of any terms or provisions of the Indenture or the Notes, unless such consideration is offered to be paid (or agreed to be paid) to all Beneficial Owners and Holders of the Notes which so consent in the time frame set forth in the solicitation documents relating to such consent.

Section 4.17. Permitted Business Activities.

The Company will not, and will not permit any Restricted Subsidiary to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material to the Company and its Restricted Subsidiaries taken as a whole.

Section 4.18. Anti-Layering.

The Company will not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Debt of the Company and senior in any respect in right of payment to the Notes. No Guarantor will incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to the Senior Debt of such Guarantor and senior in any respect in right of payment to such Guarantor’s Subsidiary Guarantee.

Section 4.19. Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of the Company may designate any Restricted Subsidiary of the Company to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary of the Company 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 properly designated will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07 hereof or represent Permitted Investments, as determined by the Company. That designation shall only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 hereof, 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 4.20. Covenant Termination.

If at any time (a) the rating assigned to the Notes by both S&P and ▇▇▇▇▇’▇ is an Investment Grade Rating and (b) no Default has occurred and is continuing under this Indenture, then upon delivery by the Company to the Trustee of an Officers’ Certificate to the foregoing effect, the Company and its Restricted Subsidiaries will no longer be subject to the following provisions of this Indenture: Sections 4.07, 4.08, 4.09, 4.10, 4.11 or 4.17 or clause (d) of Section 5.01. The Company and its Restricted Subsidiaries will remain subject to all other provisions of the Indenture.

Section 4.21. Calculation of Original Issue Discount.

The Company shall file with the Trustee promptly after the end of each calendar year for which reporting on Form 1099 OID is required (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Notes as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be required to be provided to the Trustee or the holders of the Notes pursuant to the Code, and the regulations issued thereunder; provided, however, that no notice shall be required hereunder in the event that there are no Outstanding Notes as of the end of said calendar year.

Section 4.22. Certain Transactions Prior to Reduction Cutoff Date.

Prior to the Reduction Cutoff Date, the Company shall not take any action that would result in an adjustment to the Conversion Rate under Article 11 of this Second Supplemental Indenture.

The Trustee, the Company and the successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such successor Person and such discharge and release of the Company.

(a) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness (a “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 $50.0 million or more; provided, that if any such default is cured or waived or any

Also as permitted by Section 301(19) of the Original Indenture, the first paragraph of Section 502 of the Original Indenture is hereby amended to read in its entirety as follows with respect to the Notes:

Upon any such declaration, the Reduced Principal Amount of the Notes shall become due and payable immediately, together with all accrued and unpaid interest and premium, if any, thereon. Notwithstanding the preceding, if an Event of Default specified in clause (8) or (9) of Section 501 hereof occurs with respect to the Company, any Significant Subsidiary of the Company or any group of Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes shall become due and payable without further action or notice, together with all accrued and unpaid interest and premium, if any, thereon.”

(2) in respect of a covenant or provision hereof which under Section 9.02 of the Second Supplemental Indenture cannot be modified or amended without the consent of each Holder of the Notes.

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

Section 6.05. Waiver of Usury, Stay or Extension of Laws.

Subject to applicable escheat and abandoned property laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the

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

Section 8.07. [Reserved].

Section 8.08. Discharge.

The Indenture (other than the Company’s obligations under Article 11 of the Indenture and Section 14 of the Notes) shall be satisfied and discharged (a “Discharge”) and shall cease to be of further effect as to all Notes issued hereunder, upon the terms and conditions, and subject to the exceptions, set forth in Article Four of the Original Indenture.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01. Without Consent of Holders of Notes.

Section 901 of the Original Indenture is hereby amended to read in its entirety as follows with respect to the Notes:

“Notwithstanding Section 902 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Subsidiary Guarantees without the consent of any Holder of a Note:

(1) to cure any ambiguity, defect or inconsistency;

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of the Company’s or a Guarantor’s obligations to the Holders of Notes pursuant to Article 5 or Section 10.03 of the Second Supplemental Indenture;

Notes or the Subsidiary Guarantees shall not be deemed to adversely affect the legal rights hereunder of any Holder if (A) such change is to conform a provision of this Indenture, the Notes or the Subsidiary Guarantees (a “Note Provision”) to a provision in the Existing Senior Subordinated Notes Prospectus (an “Existing Senior Subordinated Notes Prospectus Provision”), (B) such Existing Senior Subordinated Notes Prospectus Provision was intended to be a verbatim recitation of a provision in the Existing Senior Subordinated Notes Indenture (an “Existing Senior Subordinated Notes Indenture Provision”) and (C) such Note Provision is intended to be identical to such Existing Senior Subordinated Notes Indenture Provision;

(5) to secure the Notes or the Subsidiary Guarantees pursuant to the requirements of Section 4.12 of the Second Supplemental Indenture or otherwise;

(9) to evidence or provide for the acceptance of appointment under this Indenture of a successor Trustee;

(10) to add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Securities, provided that any such addition, change or elimination (A) shall neither (i) apply to any Security of any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (ii) modify the rights of the Holder of any such Security with respect to such provision or (B) shall become effective only when there is no such Security Outstanding;

(11) to establish the form or terms of Securities of any series as permitted by Sections 201 and 301;

(12) to make provision with respect to adjustments to the Conversion Rate as required by the Second Supplemental Indenture or to increase the Conversion Rate in accordance with the Second Supplemental Indenture; or

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the Opinion of Counsel described in Section 903 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.”

Section 9.02. With Consent of Holders of Notes.

Section 902 of the Original Indenture is hereby amended to read in its entirety as follows with respect to the Notes:

“Except as provided above in Section 901 and below in this Section 902, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Subsidiary Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate Reduced Principal Amount of the Notes then outstanding (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and, subject to Sections 508 and 513 hereof, any existing Default or Event of Default with respect to the Notes or compliance with any provision of this Indenture, the Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in aggregate Reduced Principal Amount of the then outstanding Notes (including consents obtained in connection with a purchase of, tender offer or exchange offer for Notes).

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the Opinion of Counsel described in Section 903 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

It shall not be necessary for the consent of the Holders of Notes under this Section 902 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 508 and 513 hereof and to the last paragraph of this Section 902, the Holders of a majority in Reduced Principal Amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected,

an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder):

(a) reduce the Reduced Principal Amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(b) reduce the Reduced Principal Amount of or change the fixed maturity of any Note or alter any of the provisions with respect to the redemption or repurchase of the Notes (except as provided in Sections 3.04, 4.10 and 4.15 of the Second Supplemental Indenture);

(d) waive a Default or Event of Default in the payment of Reduced Principal Amount of or premium, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in Reduced Principal Amount of the Notes and a waiver of the payment default that resulted from such acceleration);

(e) make any Note payable in money other than that stated in the Notes;

(f) make any change in the provisions of this Indenture relating to waivers of past Defaults or Events of Default or the rights of Holders of Notes to receive payments of Reduced Principal Amount of or premium, if any, or interest on the Notes (except as permitted in clause (g) below) or settlements due upon conversion of the Notes;

(g) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 3.04, 4.10 and 4.15 of the Second Supplemental Indenture);

(h) release any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with the terms of this Indenture;

(i) reduce the consideration due upon conversion or otherwise adversely affect the right of Holders to convert Notes in accordance with Article 11 of the Second Supplemental Indenture or modify the Reduction provisions or Mandatory Conversion provisions of the Second Supplemental Indenture in a manner adverse to Holders; or

(j) make any change in the preceding amendment, supplement and waiver provisions.

In addition, any amendment or supplement to, or waiver of, the provisions of this Indenture relating to subordination of the Notes or the Subsidiary Guarantees to Senior Debt that adversely affects the rights of the Holders of the Notes shall require the consent of the Holders of at least 75% in principal amount of Notes then outstanding.”

Section 9.03. Revocation and Effect of Consents.

A consent to any amendment, supplement or waiver under the Indenture by any Holder given in connection with a purchase, tender or exchange of such Holder’s Notes shall not be rendered invalid by such purchase, tender or exchange.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date except to the extent that the requisite number of consents to the amendment, supplement or waiver have been obtained within such 90-day period or as set forth in the next paragraph of this Section 9.03.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (a) through (i) of Section 902 of the Indenture, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

ARTICLE 10

GUARANTEES OF NOTES

The Notes shall have the benefit of Subsidiary Guarantees. The provisions of Article Thirteen of the Original Indenture shall not apply to the Notes, and in lieu thereof the following provisions of this Article 10 shall apply to the Notes.

Section 10.01. Subsidiary Guarantees.

Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees, on a senior subordinated basis in accordance with Article 14 of this Second Supplemental Indenture, 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 Second Supplemental Indenture or the Indenture, the Notes held thereby and the Obligations of the Company hereunder and thereunder, that: (a) the Reduced Principal Amount of and premium, if any, and interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise, and interest on the overdue Reduced Principal Amount of and premium, if any, and (to the extent permitted by law) interest on the Notes, and all other payment Obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full and performed, all in accordance with the terms hereof and thereof; and

(b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, upon repurchase or redemption or otherwise. Failing payment when so due of any amount so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately, subject to the provisions of Article 14 hereof. An Event of Default with respect to the Notes under the Indenture shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the Obligations of the Company.

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

If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any Custodian, Trustee or other similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to, and hereby waives, any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby.

Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Five of the Original Indenture for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article Five of the Original Indenture, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

Section 10.02. Notation of Subsidiary Guarantees.

No notation of any Subsidiary Guarantee need be endorsed on any Note, notwithstanding any contrary provision of the Original Indenture.

Section 10.03. Guarantors May Consolidate, Etc., on Certain Terms.

(a) No Guarantor shall sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person (other than the Company or another Guarantor), unless, (i) either (1) 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 Guarantor) unconditionally assumes all the obligations of such Guarantor, pursuant to a supplemental indenture, substantially in the form of Exhibit B hereto, under the Notes, the Indenture and its Subsidiary Guarantee on terms set forth therein, or (2) the Net Proceeds of such sale or other disposition are applied in accordance with the provisions of Section 4.10 hereof, and (ii) immediately after giving effect to such transaction, no Default or Event of Default exists.

(b) In the case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and substantially in the form of Exhibit B hereto, of the Subsidiary Guarantee and the due and punctual performance of all of the covenants of the Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Section 10.04. Releases of Subsidiary Guarantees.

The Subsidiary Guarantee of a Guarantor shall be released: (1) in connection with any sale or other disposition of all or substantially all of the properties or assets of such Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company, if the sale or other disposition complies with Section 4.10 hereof; or (2) in connection with any sale or other disposition of all of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company, if the sale or other disposition complies with Section 4.10 hereof; or (3) if the Company designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of the Indenture; or (4) upon Discharge in accordance with Article 8 hereof.

Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that any of the foregoing clauses (1) – (4) has occurred, the Trustee shall execute any documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee. Any Guarantor not released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of Reduced Principal Amount of, premium, if any, and interest on the Notes and for the other obligations of such Guarantor under the Indenture as provided in this Article 10.

Section 10.05. Limitation on Guarantor Liability.

The obligations of each Guarantor under its Subsidiary Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Subsidiary

Guarantee or pursuant to its contribution obligations under the Indenture, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

Section 10.06. “Trustee” to Include Paying Agent.

In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such Paying Agent were named in this Article 10 in place of the Trustee.

ARTICLE 11

CONVERSION

Section 11.01. Conversion. (a) Subject to compliance with Section 11.02, at any time following the Reduction Cutoff Date, a Holder shall have the right to convert all or any portion (if such portion is $1,000 Original Principal Amount or an integral multiple of $1,000 principal amount) of its Notes (“Early Conversion”) at any time and from time to time, on any Business Day, prior to the earliest of (i) if applicable, the close of business on the fifth Business Day following the date of a Mandatory Conversion Notice delivered in accordance with Section 11.01(c), (ii) if applicable, with respect to a Note called for redemption, the close of business on the Business Day immediately preceding the Redemption Date or (iii) the close of business on the Business Day immediately preceding the maturity date, into a number of shares of Common Stock per $1,000 Original Principal Amount of Notes being converted equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares of Common Stock in accordance with Section 11.03). In addition, upon an Early Conversion, a Holder shall have the right to receive in cash, with respect to its Notes being converted, per $1,000 Original Principal Amount of Notes being converted, accrued and unpaid interest to the Early Conversion Date in accordance with Section 11.02(b).

(b) [Reserved]

(c) Following the Reduction Cutoff Date, the Company shall have the right to convert the Notes (“Mandatory Conversion”), in whole or in part, into a number of shares of Common Stock per $1,000 Original Principal Amount of Notes equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares of Common Stock in accordance with Section 11.03), if each of the following conditions are satisfied: (i) the Daily VWAP of the Common Stock (or other security into which the Notes are convertible pursuant to Section 11.11) exceeds the Threshold Price in effect on each applicable Trading Day for at least 20 Trading Days (whether or not consecutive) during any period of 30 consecutive Trading Days commencing after the Reduction Cutoff Date (the “VWAP Condition”) and (ii) the Company delivers to the Holders, the Trustee and the Conversion Agent (if other than the Trustee) a notice of the Company’s election of its right to convert the Notes no later than the open of business on the third Business Day immediately following the 20^th Trading Day on which the Threshold Price was exceeded of any such 30 Trading Day period (a “Mandatory Conversion Notice”), which

notice shall specify that the Mandatory Conversion shall occur on the sixth Business Day following the date of such notice (the “Mandatory Conversion Date”); provided that, the Company’s right to cause a Mandatory Conversion shall be suspended during the period beginning on the date a Change of Control Offer is made and continuing to, and including, the applicable Change of Control Settlement Date. Cash equal to accrued but unpaid interest with respect to the Notes being converted pursuant to any Mandatory Conversion to but excluding the applicable Mandatory Conversion Date shall also be payable on such Mandatory Conversion Date; provided, that if such Mandatory Conversion Date occurs during the period after the close of business on any Record Date and before the opening of business on the corresponding Interest Payment Date, interest with respect to the Notes converted will be payable on such Interest Payment Date to the Holders in whose names the Notes are registered at the close of business on such Record Date. The Mandatory Conversion Notice shall state that the Company is exercising its right to cause a Mandatory Conversion, the Conversion Rate and Conversion Price in effect on the Mandatory Conversion Date.

(d) Notwithstanding the foregoing, a Reduction shall only occur, and the Company may only exercise its right to cause a Mandatory Conversion, if, as evidenced by an Officers’ Certificate delivered to the Trustee and the Conversion Agent (if other than the Trustee) on the any Reduction Settlement Date and any Mandatory Conversion Date, as applicable, all of the conditions listed below (the “Equity Conditions”) are satisfied on each day during the period (x) commencing on, and including, the date of the Reduction Notice (with respect to any Reduction Conversion) and any Mandatory Conversion Notice, as applicable, and (y) ending on, and including, the corresponding Reduction Settlement Date (with respect to any Reduction) or Mandatory Conversion Date, as applicable (the “Equity Conditions Measuring Period”). The Equity Conditions are as follows:

(i) either (1) all shares of Common Stock issuable upon conversion of the Notes and held by a non-Affiliate of the Company shall be eligible for sale without the need for registration under any applicable federal or state securities laws or (2) a shelf registration statement registering the resale of the shares of Common Stock issuable upon conversion of the Notes has been filed by the Company and been declared effective by the SEC or is automatically effective and is available for use, and the Company expects such shelf registration statement to remain effective and available for use from the applicable Reduction Date (with respect to any Reduction) or the Mandatory Conversion Date until thirty days following such date;

(ii) the Common Stock (or other security into which the Notes are convertible pursuant to Section 11.11) to be delivered on such conversion is listed or traded on The New York Stock Exchange, The NASDAQ Global Select Market, The NASDAQ Global Market, The NASDAQ Capital Market, or any of their respective successors (each, an “Eligible Market”) and shall not then be suspended from trading on such Eligible Market;

(iii) at or prior to any Mandatory Conversion Settlement Date, for any Notes validly surrendered for conversion with an Early Conversion Date prior to the Mandatory Conversion Date in accordance with the terms of this Indenture, the Company shall have delivered and paid the number of shares of Common Stock and the amount of cash due upon conversion of the Notes to the Holders in accordance with Section 11.01(a);

(iv) shares of Common Stock to be issued upon conversion may be issued in full without violating the rules or regulations of The New York Stock Exchange or any other applicable Eligible Market on which the Common Stock delivered upon conversion is then listed or trading; and

(v) no Event of Default shall have occurred and be continuing.

For the avoidance of doubt, the Company may exercise its right to cause more than one Mandatory Conversion so long as any Notes are outstanding so long as it complies with the other requirements of this Section 11.01(d). If the Company exercises its right to cause a Mandatory Conversion in part, the Conversion Agent will select the Notes to be converted pro rata, by lot or by any other method the Conversion Agent in its sole discretion deems fair and appropriate (or, in the case of Notes represented by Global Notes, in such manner as The Depository Trust Company, a New York corporation (“DTC”) may require), in denominations of Original Principal Amount of $1,000 or any integral $1,000 multiple in excess thereof.

Section 11.02. Conversion Procedure and Payment Upon Conversion.

(a) To convert its Note pursuant to an Early Conversion, a Holder of a definitive Note must:

(1) complete and manually sign the Conversion Notice, with appropriate signature guarantee, or facsimile of the Conversion Notice and deliver the completed Conversion Notice (which shall be irrevocable) to the Conversion Agent;

(2) surrender the Note to the Conversion Agent;

(3) furnish appropriate endorsements and transfer documents if required by the Security Registrar or Conversion Agent; and

(4) pay all transfer or similar taxes if required pursuant to Section 11.04.

If a Holder holds a beneficial interest in a Note that is a Global Security (a “Global Note”), to convert such Note, the Holder must comply with clause (4) above and the Depositary’s procedures for converting a beneficial interest in a Global Note.

(b) (1) Upon conversion of a Holder’s Note in an Early Conversion, the Company shall deliver to such converting Holder, through the Conversion Agent, a number of shares of Common Stock per $1,000 Original Principal Amount of Notes being converted equal to the Conversion Rate in effect on the applicable Early Conversion Date (plus cash in lieu of fractional shares in accordance with Section 11.03). In addition, the Company shall deliver, through the Conversion Agent, with respect to the Notes being converted, cash in an amount per $1,000 Original Principal Amount of Notes equal to accrued and unpaid interest to the Early Conversion Date. If a Holder converts more than one Note at the same time, the full number of shares of Common Stock issued upon such conversion (and, as a result, the amount of cash

deliverable in lieu of any fractional share of Common Stock) and the amount of cash deliverable in respect of accrued and unpaid interest shall be based on the aggregate Reduced Principal Amount of Notes converted by such Holder; provided, that if the Conversion Date with respect to any Note converted pursuant to Early Conversion occurs during the period after the close of business on any Record Date and before the opening of business on the corresponding Interest Payment Date, interest with respect to the Notes converted will be payable on such Interest Payment Date to the Holders in whose names the Notes are registered at the close of business on such Record Date. Settlement shall occur on the third Business Day immediately following the applicable Early Conversion Date.

(2) Upon conversion of the Notes in a Mandatory Conversion, the Company shall deliver to each Holder, through the Conversion Agent, a number of shares of Common Stock per $1,000 Original Principal Amount of Notes equal to the Conversion Rate in effect on the applicable Mandatory Conversion Date (plus cash in lieu of fractional shares in accordance with Section 11.03). The full number of shares of Common Stock issued upon such conversion (and, as a result, the amount of cash deliverable in lieu of any fractional share of Common Stock) shall be based on the aggregate Reduced Principal Amount of Notes outstanding. Settlement shall occur on the third Business Day immediately following the applicable Mandatory Conversion Date.

(3) The shares of Common Stock due upon conversion of a Global Note shall be delivered by the Company in accordance with the Depositary’s customary practices.

(c) A Note shall be deemed to have been converted (in each case, the “Conversion Date”) (i) immediately prior to the close of business on the date that the Holder has complied with the requirements set forth in Section 11.02(a) with respect to an Early Conversion, and (ii) immediately prior to the close of business on the Mandatory Conversion Date with respect to a Note subject to Mandatory Conversion. The Person in whose name the shares of Common Stock shall be issued upon any conversion pursuant to this Article 11 shall become the holder of record of such shares as of the close of business on the applicable Conversion Date. Prior to such time, a Holder receiving shares of Common Stock upon conversion shall not be entitled to any rights relating to such shares of Common Stock, including, among other things, the right to vote, tender in a tender offer and receive dividends and notices of shareholder meetings. On and after the close of business on the applicable Conversion Date with respect to a conversion of a Note pursuant hereto, all rights of the Holder of such Note shall terminate, other than the right to receive the consideration deliverable or payable upon conversion of such Note as provided in this Article 11.

(d) Upon surrender of a Note that is converted in part, the Trustee shall authenticate for the Holder a new Note equal in Original Principal Amount with the Reduced Principal Amount reflected thereon to the unconverted portion of the Note.

Section 11.03. Cash in Lieu of Fractional Shares. The Company will not issue a fractional share of Common Stock upon conversion of a Note. Instead, the Company shall pay cash in lieu of fractional shares based on the Daily VWAP of the Common Stock on the applicable Conversion Date (or, if such Conversion Date is not a Trading Day, the Daily VWAP of the Common Stock on the Trading Day immediately preceding such Conversion Date).

Section 11.04. Taxes on Conversion. The Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of Common Stock upon the conversion of a Note. However, such Holder shall pay any such tax or duty that is due because such shares are issued in a name other than such Holder’s name. The Conversion Agent may refuse to deliver a certificate representing the Common Stock to be issued in a name other than such Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax or duty which will be due because such shares are to be issued in a name other than such Holder’s name.

Section 11.05. Company to Reserve, Provide and List Common Stock. The Company shall at all times reserve out of its authorized but unissued Common Stock or Common Stock held in its treasury a sufficient number of shares of Common Stock to permit the Reduction and conversion, in accordance herewith, of all of the Notes (assuming, for such purposes, that at the time of computation of such number of shares, all such Notes would be held or converted by a single Holder, as applicable).

All shares of Common Stock issued upon Reduction or conversion of the Notes shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim that arises from the action or inaction of the Company.

The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon Reduction or conversion of Notes and shall list such shares on each national securities exchange or automated quotation system on which the shares of Common Stock are listed on the applicable Reduction Date or Conversion Date.

Section 11.06. Adjustment of Conversion Rate. The Conversion Rate shall be subject to adjustment from time to time, without duplication, upon the occurrence of any of the following events:

(a) If the Company issues shares of Common Stock as a dividend or distribution on all shares of the Common Stock, or if the Company effects a share split or share combination (including a “reverse split”), the Conversion Rate shall be adjusted based on the following formula:

CR’

CR₀

OS’

OS₀

where,


CR₀ =		the Conversion Rate in effect immediately prior to the close of business on the record date for such dividend or distribution, or immediately prior to open of business on the effective date of such share split or share combination, as the case may be;


CR’ =		the Conversion Rate in effect immediately after the close of business on the record date for such dividend or distribution, or immediately after the open of business on the effective date of such share split or share combination, as the case may be;

OS₀ =		the number of shares of Common Stock outstanding immediately prior to the close of business on the record date for such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as the case may be; and

OS’ =		the number of shares of Common Stock outstanding immediately after such dividend or distribution, or such share split or share combination, as the case may be.

Any adjustment made under this Section 11.06(a) shall become effective immediately after the close of business on the record date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this Section 11.06(a) is declared but not so paid or made, then the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) In addition to the foregoing adjustments in subsection (a) above, the Company may, from time to time and to the extent permitted by law, increase the Conversion Rate by any amount for a period of at least 20 Business Days or any longer period as may be permitted or required by law, if the Board of Directors has made a determination, which determination shall be conclusive, that such increase would be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give notice to the Trustee and cause notice of such increase to be mailed to each Holder of Notes at such Holder’s address as the same appears on the registry books of the Security Registrar at least 15 days prior to the date on which such increase commences.

(c) All calculations under this Article 11 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be. Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000th.

Section 11.07. No Adjustment. The Conversion Rate shall not be adjusted for any transaction or event other than as specified in this Article 11.

Section 11.08. Adjustments for Tax Purposes. Except as prohibited by law, the Company may (but is not obligated to) increase the Conversion Rate, in addition to those required by Section 11.06 hereof, as it determines to be advisable in order that any dividend, distribution, share split or share combination will not be taxable to the recipients thereof or in order to avoid or diminish any such taxation.

Section 11.09. Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the Security Registrar’s

books a notice of the adjustment and file with the Trustee and the Conversion Agent an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the correctness of such adjustment.

Section 11.10. Notice of Certain Transactions. In the event that:

(a) the Company takes any action that would require an adjustment in the Conversion Rate,

(b) the Company takes any action that would require a supplemental indenture pursuant to Section 11.11, or

the Company shall promptly mail to Holders at the addresses appearing on the Registrar’s books and the Trustee a written notice stating the proposed record date and effective date of the transaction referred to in clause (a), (b) or (c) of this Section 11.10.

Section 11.11. Effect of Reclassifications, Consolidations, Mergers, Binding Share Exchanges or Sales on Conversion Privilege. If the Company:

(a) reclassifies the Common Stock (other than a change only in par value, or from par value to no par value, or from no par value to par value, or a change as a result of a subdivision or combination of Common Stock to which Section 11.06(a) applies);

(b) is party to a consolidation, merger or binding share exchange; or

(c) sells, transfers, leases, conveys or otherwise disposes of all or substantially all of the consolidated property or assets of the Company,

in each case, pursuant to which the Common Stock would be converted into or exchanged for, or would constitute solely the right to receive, cash, securities or other property (any such event, a “Merger Event”), each $1,000 Original Principal Amount of Notes will, from and after the effective time of such Merger Event, in lieu of being convertible into Common Stock, be convertible into the same kind, type and proportions of consideration that a holder of a number of shares of Common Stock equal to the Conversion Rate (and if applicable, the Daily Reduction Rate) in effect immediately prior to such Merger Event would have received in such Merger Event (“Reference Property”) and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture providing for such change in the right to convert the Notes.

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then:

(i) the Reference Property into which the Notes will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election; and

(ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock.

The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

The supplemental indenture referred to in the first sentence of this Section 11.11 shall, in the good faith judgment of the Company as evidenced by an Officers’ Certificate, (i) provide for adjustments to the Conversion Rate that shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article 11 and for the delivery of cash by the Company in lieu of fractional securities or property that would otherwise be deliverable to Holders upon conversion as part of the Reference Property, with such amount of cash determined by the Company in a manner as nearly equivalent as may be practicable to that used by the Company to determine the Daily VWAP of the Common Stock and (ii) provide that after the Merger Event, the VWAP Condition (and related calculations) shall be determined with reference to the trading value of the Reference Property as determined in good faith by the Company in a manner as nearly equivalent as may be practicable to that used by the Company to determine the Daily VWAP of the Common Stock. If the Reference Property includes shares of stock, other securities or other property or assets (including any combination thereof) of a company other than the Company or the successor or purchasing entity, as the case may be, in such Merger Event, then such other company shall also execute such supplemental indenture, and such supplemental indenture shall contain such additional provisions to protect the interests of the Holders, including the right of Holders to require the Company to repurchase their Notes upon a Change of Control in accordance with Section 4.15, as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 11.11 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances or dispositions.

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 11.11.

None of the foregoing provisions shall affect the right of a Holder to convert its Notes into shares of Common Stock (and cash in lieu of any fractional share) as set forth in Section 11.01(a) and Section 11.02 prior to the effective date of such Merger Event, or the right of the Company to effect any Mandatory Conversion in accordance with Section 11.01(c).

In the event the Company shall execute a supplemental indenture pursuant to this Section 11.11, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Notes upon the conversion of their Notes after any such Merger Event and any adjustment to be made with respect thereto.

Section 11.12. Notice to Holders.

The Company shall cause to be filed with the Trustee and the Conversion Agent and to be mailed to each Holder at its address appearing on the applicable Security Register a copy of any notice sent to the holders of the Company’s 1.25% Convertible Senior Notes due 2020 (the “Existing 2020 Convertible Notes”) pursuant to Section 14.10 of the Indenture dated as of March 27, 2015 (as amended, the “Existing 2020 Convertible Notes Indenture”) among the Company, the guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as Trustee, as soon as practicable after such notice is sent to such holders; provided that in the event the Existing 2020 Convertible Notes are repaid, prepaid, redeemed, defeased, retired or otherwise cease to exist, then the Company shall mail to each Holder at its address appearing on the applicable Security Register any notices that would have been required to be sent to the holders of the Existing 2020 Convertible Notes pursuant to Section 14.10 of the Existing 2020 Convertible Notes Indenture were the Existing 2020 Convertible Notes still outstanding.

Section 11.13. Trustee’s Disclaimer.

Neither the Trustee nor the Conversion Agent shall have any duty to determine when an adjustment under this Article 11 should be made, how it should be made or what such adjustment should be, but the Trustee and the Conversion Agent may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee and the Conversion Agent pursuant to Section 11.09 hereof and the Company agrees to deliver such Officers’ Certificate to the Trustee and the Conversion Agent promptly after the occurrence of any such adjustment. Neither the Trustee nor the Conversion Agent shall be accountable with respect to, and makes no representation as to, the validity or value of any securities or assets issued upon conversion of Notes, and neither the Trustee nor the Conversion Agent shall be responsible for the failure by the Company to comply with any provisions of this Article 11.

Neither the Trustee nor the Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 11.11, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee and the Conversion Agent pursuant to Section 11.11 hereof.

The Trustee and the Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Notes to either calculate the Conversion Price or determine whether any facts exist which may require any adjustment of the Conversion Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed herein, or in any supplemental indenture provided to be employed, in making the same and shall be protected in relying upon an Officers’ Certificate with respect to the same. Neither the Trustee nor the Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of Common Stock or stock or share certificates or other securities or property upon the surrender of any Note for the purpose of conversion; and the Trustee and the Conversion Agent shall not be responsible or liable for any failure of the Company to comply with any of the covenants of the Company

contained in this Article. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 11.01 has occurred which makes the Securities eligible for conversion until the Company has delivered to the Trustee and the Conversion Agent an Officers’ Certificate stating that such event has occurred, on which certificate the Trustee and any the Conversion Agent may conclusively rely, and the Company agrees to deliver such Officers’ Certificate to the Trustee and the Conversion Agent promptly after the occurrence of any such event.

ARTICLE 13

SUBORDINATION

In accordance with Section 301(3) of the Original Indenture, the following provisions of this Article 13 shall apply to the Notes in lieu of the provisions of Article Twelve of the Original Indenture.

Section 13.01. Agreement to Subordinate.

The Company agrees, and each Noteholder by accepting a Note agrees, that the payment of the Reduced Principal Amount of, premium, if any, and interest on the Notes and any other Obligation of the Company in respect of the Notes (including any obligation to purchase Notes) is subordinated in right of payment, to the extent and in the manner provided in this Article 13, to the prior payment in full in cash of all Obligations in respect of Senior Debt of the Company, including the Obligations of the Company under the Credit Agreement, whether outstanding on the date of this Second Supplemental Indenture or thereafter incurred, and that the subordination is for the benefit of and shall be enforceable directly by the holders of such Senior Debt. The Notes shall rank equally in right of payment with the all other Senior Subordinated Debt of the Company, and only Indebtedness of the Company that is Senior Debt of the Company shall rank senior in right of payment to the Notes in accordance with the provisions set forth herein. All provisions of this Article 13 shall be subject to Section 13.12 hereof. All references to “Senior Debt” in this Article 13 are to Senior Debt of the Company.

Section 13.02. Liquidation, Dissolution, Bankruptcy.

Upon any payment or other distribution of the assets of the Company to creditors upon a liquidation or dissolution of the Company, or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, or in an assignment for the benefit of creditors or in any marshaling of the Company’s assets and liabilities:

(1) holders of Senior Debt of the Company shall be entitled to receive payment in full in cash of all Obligations due in respect of such Senior Debt (including interest after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Debt, whether or not an allowable claim in such proceeding) before Noteholders shall be entitled to receive any payment with respect to the Notes; and

(2) until all Obligations with respect to such Senior Debt are paid in full in cash, any payment or other distribution to which Noteholders would be entitled but for this Article 13 shall be made to holders of such Senior Debt as their interests may appear, except that Noteholders may receive and retain Permitted Junior Securities and payments made from a trust already established pursuant to Article 8 of this Second Supplemental Indenture or Article Four of the Original Indenture.

Section 13.03. Default on Senior Debt.

The Company shall not pay the Reduced Principal Amount of, premium, if any, or interest on the Notes or make any deposit pursuant to Article 8 of this Second Supplemental Indenture or Article Four of the Original Indenture and shall not purchase, redeem or otherwise

retire any Notes or make any other payment with respect to the Notes (collectively, “pay the Notes”), except that Noteholders may receive and retain Permitted Junior Securities and payments made from a trust already established pursuant to Article 8 hereof or Article Four of the Original Indenture, if either:

(1) a default (a “payment default”) in the payment of the principal of, premium, if any, or interest on, or any other Obligation in respect of, any Designated Senior Debt occurs and is continuing beyond any applicable grace period; or

(2) any other default (a “nonpayment default”) occurs and is continuing with respect to any Designated Senior Debt that permits holders of such Designated Senior Debt to accelerate its maturity (or that would permit such holders to accelerate with the giving of notice or the passage of time or both) and the Trustee receives a notice of such default (a “Payment Blockage Notice”) from the Company or the holders of such Designated Senior Debt.

Except as provided in Section 13.02 hereof, payments on the Notes may and shall be resumed:

(1) in the case of a payment default, upon the date on which such default is cured or waived; and

(2) in the case of a nonpayment default, upon the earlier of the date on which such nonpayment default is cured or waived or 179 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has been accelerated.

No new Payment Blockage Notice may be delivered unless and until 360 days have elapsed since the delivery of the immediately prior Payment Blockage Notice. No nonpayment default that existed or was continuing with respect to any Designated Senior Debt on the date of delivery of any Payment Blockage Notice to the Trustee with respect to such Designated Senior Debt shall be, or be made, the basis for a subsequent Payment Blockage Notice unless such default has been cured or waived for a period of not less than 90 days.

Section 13.04. Acceleration of Payment of Notes.

If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify the holders of Designated Senior Debt (or their Representatives) of the acceleration.

Section 13.05. When Distribution Must Be Paid Over; Reinstatement of Senior Debt.

If a payment or other distribution is made to the Trustee or any of the Noteholders that because of this Article 13 should not have been made to them, the Trustee or any of the Noteholders who receive the distribution shall hold it in trust for holders of Senior Debt of the Company and (in the case of the Trustee, if still in its possession) pay it over and deliver it to them (or their Representatives) as their interests may appear.

To the extent any payment of or distribution in respect of Senior Debt (whether by or on behalf of the Company as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or distribution is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person, the Senior Debt or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred.

Section 13.06. Subrogation.

After all Senior Debt of the Company is paid in full (and all commitments with respect to such Senior Debt have terminated) and until the Notes are paid in full, Noteholders shall be subrogated to the rights of holders of such Senior Debt to receive distributions applicable to such Senior Debt. A distribution made under this Article 13 to holders of such Senior Debt which otherwise would have been made to Noteholders is not, as between the Company and Noteholders, a payment by the Company on such Senior Debt.

Section 13.07. Relative Rights.

This Article 13 defines the relative rights of Noteholders and holders of Senior Debt of the Company. Nothing in the Indenture shall:

(1) impair, as between the Company and Noteholders, the obligation of the Company, which is absolute and unconditional, to pay Reduced Principal Amount of, premium, if any, and interest on the Notes in accordance with their terms; or

(2) prevent the Trustee or any Noteholder from exercising its available remedies upon an Event of Default, subject to the rights of holders of Senior Debt to receive payments and distributions otherwise payable to Noteholders and to block payments on the Notes as provided in this Article 13.

Section 13.08. Subordination May Not Be Impaired by Company.

No right of any present or future holders of any Senior Debt to enforce subordination as provided in this Article 13 will at any time in any way be prejudiced or impaired by noncompliance by the Company with the terms of the Indenture, regardless of any knowledge thereof that any such holder of Senior Debt may have or otherwise be charged with.

Section 13.09. Rights of Trustee and Paying Agent; Rights of Holders of Senior Debt.

Notwithstanding Section 13.03 hereof, the Trustee or Paying Agent shall continue to make payments on the Notes and shall not be charged with knowledge of the existence of facts that under this Article 13 would prohibit the making of any such payments unless, not less than one Business Day prior to the date of such payment, a Responsible Officer of the Trustee receives written notice that such payments are prohibited by this Article 13. The Company, the Registrar, the Paying Agent, a Representative or a holder of Senior Debt shall be entitled to give the notice; provided, however, that, if an issue of Senior Debt has a Representative, only the Representative shall be entitled to give the notice.

The Trustee in its individual or any other capacity shall be entitled to hold Senior Debt with the same rights it would have if it were not Trustee. The Registrar and the Paying Agent shall be entitled to do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 13 with respect to any Senior Debt which may at any time be held by it, to the same extent as any other holder of such Senior Debt; and nothing in Article Six of the Original Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 13 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607 of the Original Indenture.

The holders of Senior Debt may, at any time and from time to time subject to the terms of such Senior Debt, without the consent of or notice to the Trustee or the Noteholders, without incurring responsibility to the Noteholders and without impairing or releasing the subordination provided in the Indenture or the obligations hereunder of the Noteholders to the holders of Senior Debt, do any one or more of the following:

(1) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Debt or any instrument evidencing the same or any agreement under which Senior Debt is outstanding or secured;

(2) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt;

(3) release any Person liable in any manner for the collection of Senior Debt; and

(4) exercise or refrain from exercising any rights against the Company and any other Person.

Section 13.10. Distribution or Notice to Representative.

Whenever any Person is to make a distribution or give a notice to holders of Senior Debt of the Company, such Person shall be entitled to make such distribution or give such notice to their Representative (if any).

Section 13.11. Not to Prevent Events of Default or Limit Right to Accelerate.

The failure to make a payment pursuant to the Notes by reason of any provision in this Article 13 shall not be construed as preventing the occurrence of a Default. Nothing in this Article 13 shall have any effect on the right of the Noteholders or the Trustee to accelerate the maturity of the Notes.

Section 13.12. Trust Moneys Not Subordinated.

Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of Government Securities held in trust under Article 8 hereof or Article Four of the Original Indenture by the Trustee for the payment of Reduced Principal Amount of, premium, if

any, and interest on the Notes shall not be subordinated to the prior payment of any Senior Debt or subject to the restrictions set forth in this Article 13, and none of the Noteholders shall be obligated to pay over any such amount to the Company or any holder of Senior Debt or any other creditor of the Company.

Section 13.13. Trustee Entitled to Rely.

Upon any payment or distribution pursuant to this Article 13, the Trustee and the Noteholders shall be entitled to rely (1) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 13.02 hereof are pending, (2) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Noteholders or (3) upon the Representatives of Senior Debt for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of such Senior Debt and other Debt of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 13. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article 13, the Trustee shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 13, and, if such evidence is not furnished, the Trustee shall be entitled to defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 601 and 603 of the Original Indenture shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 13.

Section 13.14. Trustee to Effectuate Subordination.

Each Noteholder by accepting a Note authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 13 and appoints the Trustee as attorney-in-fact for any and all such purposes.

Section 13.15. Trustee Not Fiduciary for Holders of Senior Debt.

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and, subject to Section 601 of the Original Indenture, shall not be liable to any such holders if it shall mistakenly pay over or distribute to Noteholders or the Company or any other Person, money or assets to which any holders of Senior Debt shall be entitled by virtue of this Article 13 or otherwise.

Section 13.16. Reliance by Holders of Senior Debt on Subordination Provisions.

Each Noteholder by accepting a Note acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Debt, whether such Senior Debt was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Senior Debt, and such holder of such Senior Debt shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Debt.

ARTICLE 14

SUBORDINATION OF SUBSIDIARY GUARANTEES

In accordance with Section 301(3) of the Original Indenture, the following provisions of this Article 14 shall apply to the Notes in lieu of the provisions of Article Fourteen of the Original Indenture.

Section 14.01. Agreement to Subordinate.

Each Guarantor agrees, and each Noteholder by accepting a Note agrees, that the payment of such Guarantor’s Subsidiary Guarantee (including any amounts in respect of the Reduced Principal Amount of, premium, if any, or interest on the Notes and any other Obligation in respect of the Notes, including any obligation of the Company to purchase Notes) is subordinated in right of payment, to the extent and in the manner provided in this Article 14, to the prior payment in full in cash of all Obligations in respect of Senior Debt of such Guarantor, including such Guarantor’s Obligations under the Credit Agreement, whether outstanding on the date of this Second Supplemental Indenture or thereafter incurred, and that the subordination is for the benefit of and shall be enforceable directly by the holders of such Senior Debt. The Subsidiary Guarantee of a Guarantor shall rank equally in right of payment with its guarantee of all other Senior Subordinated Debt of such Guarantor, and only Indebtedness of such Guarantor that is Senior Debt of such Guarantor shall rank senior in right of payment to the Subsidiary Guarantee of such Guarantor in accordance with the provisions set forth herein. All provisions of this Article 14 shall be subject to Section 14.12 hereof. All references to “Senior Debt” in this Article 14 are to Senior Debt of the Guarantors.

Section 14.02. Liquidation, Dissolution, Bankruptcy.

Upon any payment or other distribution of the assets of any Guarantor to creditors upon a liquidation or dissolution of such Guarantor, or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such Guarantor or its property, or in an assignment for the benefit of creditors or in any marshaling of such Guarantor’s assets and liabilities:

(1) holders of Senior Debt of such Guarantor shall be entitled to receive payment in full in cash of all Obligations due in respect of such Senior Debt (including interest after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Debt, whether or not an allowable claim in such proceeding) before Noteholders shall be entitled to receive any payment pursuant to the Subsidiary Guarantee of such Guarantor; and

(2) until all Obligations with respect to the Senior Debt of such Guarantor are paid in full in cash, any payment or other distribution to which Noteholders would be entitled but for this Article 14 shall be made to holders of such Senior Debt as their interests may appear, except that Noteholders may receive and retain Permitted Junior Securities and payments made from a trust already established pursuant to Article 8 of this Second Supplemental Indenture or Article Four of the Original Indenture.

Section 14.03. Default on Senior Debt.

No Guarantor shall make any payment under its Subsidiary Guarantee, whether in respect of the Reduced Principal Amount of, premium, if any, or interest on the Notes or make any deposit pursuant to Article 8 of this Second Supplemental Indenture or Article Four of the Original Indenture and shall not purchase, redeem or otherwise retire any Notes or make any other payment with respect to the Notes (collectively, “pay its Subsidiary Guarantee”), except that Noteholders may receive and retain Permitted Junior Securities and payments made from a trust already established pursuant to Article 8 of this Second Supplemental Indenture or Article Four of the Original Indenture, if either:

(1) a default (a “payment default”) in the payment of the principal of, premium, if any, or interest on, or any other Obligation in respect of, any Designated Senior Debt of such Guarantor occurs and is continuing beyond any applicable grace period; or

(2) any other default (a “nonpayment default”) occurs and is continuing with respect to any Designated Senior Debt of such Guarantor that permits holders of such Designated Senior Debt to accelerate its maturity (or that would permit such holders to accelerate with the giving of notice or the passage of time or both) and the Trustee receives a notice of such default (a “Subsidiary Guarantee Payment Blockage Notice”) from such Guarantor or the holders of such Designated Senior Debt.

Except as provided in Section 14.02 hereof, payments on the Subsidiary Guarantees may and shall be resumed:

(1) in the case of a payment default, upon the date on which such default is cured or waived; and

(2) in the case of a nonpayment default, upon the earlier of the date on which such nonpayment default is cured or waived or 179 days after the date on which the applicable Subsidiary Guarantee Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has been accelerated.

No new Subsidiary Guarantee Payment Blockage Notice may be delivered unless and until 360 days have elapsed since the delivery of the immediately prior Subsidiary Guarantee Payment Blockage Notice. No nonpayment default that existed or was continuing with respect to any Designated Senior Debt on the date of delivery of any Subsidiary Guarantee Payment Blockage Notice to the Trustee with respect to such Designated Senior Debt shall be, or be made, the basis for a subsequent Subsidiary Guarantee Payment Blockage Notice unless such default has been cured or waived for a period of not less than 90 days.

Section 14.04. Demand for Payment.

If a demand for payment is made by the Trustee on a Guarantor pursuant to Article 10, such Guarantor shall promptly notify the holders of Designated Senior Debt of such Guarantor (or their Representatives) of such demand.

Section 14.05. When Distribution Must Be Paid Over; Reinstatement of Senior Debt.

If a distribution is made to the Trustee or any of the Noteholders that because of this Article 14 should not have been made to them, the Trustee or any of the Noteholders who receive the distribution shall hold it in trust for holders of Senior Debt of the applicable Guarantor and (in the case of the Trustee, to the extent still in its possession) pay it over and deliver it to them (or their Representatives) as their interests may appear.

To the extent any payment of or distribution in respect of Senior Debt (whether by or on behalf of any Guarantor as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or distribution is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other similar Person, the Senior Debt or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred.

Section 14.06. Subrogation.

After all Senior Debt of a Guarantor is paid in full (and all commitments with respect to such Senior Debt have terminated) and until the Notes are paid in full, Noteholders shall be subrogated to the rights of holders of such Senior Debt to receive distributions applicable to Senior Debt of such Guarantor. A distribution made under this Article 14 to holders of such Senior Debt which otherwise would have been made to Noteholders is not, as between the relevant Guarantor and Noteholders, a payment by such Guarantor on such Senior Debt.

Section 14.07. Relative Rights.

This Article 14 defines the relative rights of Noteholders and holders of Senior Debt of a Guarantor. Nothing in the Indenture shall:

(1) impair, as between a Guarantor and Noteholders, the obligation of such Guarantor, which is absolute and unconditional, to pay its Subsidiary Guarantee to the extent set forth in Article 10; or

(2) prevent the Trustee or any Noteholder from exercising its available remedies upon a default by such Guarantor under its Subsidiary Guarantee, subject to the rights of holders of Senior Debt of such Guarantor to receive payments and distributions otherwise payable to Noteholders and to block payments on the Notes as provided in this Article 14.

Section 14.08. Subordination May Not Be Impaired by Guarantors.

No right of any present or future holders of any Senior Debt of any Guarantor to enforce subordination as provided in this Article 14 will at any time in any way be prejudiced or impaired by noncompliance by such Guarantor with the terms of the Indenture, regardless of any knowledge thereof that any such Holder of Senior Debt may have or otherwise be charged with.

Section 14.09. Rights of Trustee and Paying Agent; Rights of Holders of Senior Debt.

Notwithstanding Section 14.03 hereof, the Trustee or Paying Agent shall continue to make payments on any Subsidiary Guarantee and shall not be charged with knowledge of the existence of facts that under this Article 14 would prohibit the making of any such payments unless, not less than one Business Day prior to the date of such payment, a Responsible Officer of the Trustee receives written notice that such payments are prohibited by this Article 14. The Company, the relevant Guarantor, the Registrar, the Paying Agent, a Representative or a holder of Senior Debt of such Guarantor shall be entitled to give the notice; provided, however, that, if an issue of Senior Debt of any Guarantor has a Representative, only the Representative shall be entitled to give the notice.

The Trustee in its individual or any other capacity shall be entitled to hold Senior Debt of any Guarantor with the same rights it would have if it were not the Trustee. The Registrar and the Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article 14 with respect to any Senior Debt of any Guarantor which may at any time be held by it, to the same extent as any other holder of such Senior Debt; and nothing in Article Six of the Original Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 14 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607 of the Original Indenture.

(2) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt;

(3) release any Person liable in any manner for the collection of Senior Debt; and

(4) exercise or refrain from exercising any rights against any Guarantor and any other Person.

Section 14.10. Distribution or Notice to Representative.

Whenever any Person is to make a distribution or give a notice to holders of Senior Debt of any Guarantor, such Person shall be entitled to make such distribution or give such notice to their Representative (if any).

Section 14.11. Article 14 Not to Prevent Events of Default or Limit Right to Demand Payment.

The failure to make a payment pursuant to a Subsidiary Guarantee by reason of any provision in this Article 14 shall not be construed as preventing the occurrence of a Default. Nothing in this Article 14 shall have any effect on the right of the Noteholders or the Trustee to make a demand for payment on any Guarantor pursuant to its Subsidiary Guarantee.

Section 14.12. Trust Moneys Not Subordinated.

Notwithstanding anything contained herein to the contrary, payments from money held in trust under Article 8 hereof or Article Four of the Original Indenture by the Trustee for the payment of principal of, premium, if any, and interest on the Notes shall not be subordinated to the prior Reduced Payment Amount of any Senior Debt of any Guarantor or subject to the restrictions set forth in this Article 14, and none of the Noteholders shall be obligated to pay over any such amount to any Guarantor or any holder of Senior Debt of any Guarantor or any other creditor of any Guarantor.

Section 14.13. Trustee Entitled to Rely.

Upon any payment or distribution pursuant to this Article 14, the Trustee and the Noteholders shall be entitled to rely (1) upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 14.02 hereof are pending, (2) upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or to the Noteholders or (3) upon the Representatives for the holders of Senior Debt of any Guarantor for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of such Senior Debt and other Debt of such Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 14. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Debt of any Guarantor to participate in any payment or distribution pursuant to this Article 14, the Trustee shall be entitled to request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt of such Guarantor held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article 14, and, if such evidence is not furnished, the Trustee shall be entitled to defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 601 and 603 of the Original Indenture shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article 14.

Section 14.14. Trustee to Effectuate Subordination.

Each Noteholder by accepting a Note authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 14 and appoints the Trustee as attorney-in-fact for any and all such purposes.

Section 14.15. Trustee Not Fiduciary for Holders of Senior Debt of Guarantors.

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt of any Guarantor and, subject to Section 601 of the Original Indenture, shall not be liable to any such holders if it shall mistakenly pay over or distribute to Noteholders or the Company or any other Person, money or assets to which any holders of such Senior Debt shall be entitled by virtue of this Article 14 or otherwise.

Section 14.16. Reliance by Holders of Senior Debt of Guarantors on Subordination Provisions.

Each Noteholder by accepting a Note acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Senior Debt of any Guarantor, whether such Senior Debt was created or acquired before or after the issuance of the Notes, to acquire and continue to hold, or to continue to hold, such Senior Debt and such holder of Senior Debt shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Debt.

[FORM OF REVERSE SIDE OF NOTE]

6¹⁄₂% Senior Subordinated Mandatory Convertible Note due 2018, Series A-1

Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. Interest. ▇▇▇▇▇▇▇ Petroleum Corporation, a Delaware corporation (the “Company”), promises to pay interest on the Reduced Principal Amount of this Note at 6.50% per annum until maturity. The Company will pay interest semi-annually in arrears on April 1 and October 1 of each year, commencing October 1, 2016, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from April 1, 2016; provided that if there is no existing Default or Event of Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue Reduced Principal Amount and premium, if any, from time to time on demand at a rate that is the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. The Company will pay interest on the Reduced Principal Amount of the Notes to the Persons who are registered Holders of Notes at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 307 of the Original Indenture with respect to Defaulted Interest. Holders must surrender Notes to the Paying Agent to collect payments of Reduced Principal Amount and premium, if any, together with accrued and unpaid interest due at maturity. The Notes will be payable as to Reduced Principal Amount, premium, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the Security Register of Holders, and provided that payment by wire transfer of immediately available funds will be required with respect to any amounts due on all Global Securities and all other Notes the Holders of which shall have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

3. Paying Agent, Security Registrar and Conversion Agent. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, will act as Paying Agent, Security Registrar and Conversion Agent. The Company may change any Paying Agent, Security Registrar or Conversion Agent without notice to any Holder. The Company or any of its Domestic Subsidiaries may act in any such capacity.

4. Indenture. This Note is one of a duly authorized issue of the series of Securities of the Company designated as its 6¹⁄₂% Senior Subordinated Mandatory Convertible Notes due 2018, Series A-1 (the “Notes”), issued under a Subordinated Indenture, dated as of March 23, 2016

A - 3

(“Original Indenture”), among the Company, the Guarantors and the Trustee, as supplemented and amended by the Second Supplemental Indenture (herein so called), dated as of July 1, 2016 (the Original Indenture, as so supplemented and amended, being called herein the “Indenture”). Capitalized terms herein are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those set forth in the TIA made part of the Indenture pursuant to Section 1.04 of the Second Supplemental Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. The Notes are unsecured senior subordinated obligations of the Company limited to $26,167,000 aggregate Original Principal Amount in the case of Notes issued on the Issue Date. The Company may, subject to Sections 2.05 and 4.09 of the Second Supplemental Indenture, issue Additional Notes under the Indenture after the Issue Date in either a limited or an unlimited aggregate principal amount. Any Additional Notes so issued and the Initial Notes shall be treated as a single class under the Indenture.

5. Optional Redemption.

The Company may on any one or more occasions redeem the Notes, in whole or in part, upon prior notice as set forth in Paragraph 8, at a Redemption Price equal to (i) 101.625% of the principal amount thereof, in the case of a redemption prior to October 1, 2016, or (ii) 100% of the Reduced Principal Amount thereof, in the case of a redemption on or after October 1, 2016, in each case, plus accrued and unpaid interest, if any, to the applicable Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date).

6. Mandatory Redemption.

Except as set forth in paragraph 7 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders.

7. Repurchase at Option of Holder.

(a) Within 30 days following the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $1,000 or any integral $1,000 multiple in excess thereof) of each Holder’s Notes at a purchase price equal to 101% of the aggregate Reduced Principal Amount of Notes repurchased, plus accrued and unpaid interest, if any, to the date of settlement (the “Change of Control Settlement Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Settlement Date. Within 30 days following a Change of Control, the Company shall mail a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction that constitutes the Change of Control and setting forth the procedures governing the Change of Control Offer as required by Section 4.15 of the Second Supplemental Indenture.

(b) On the 361st day after an Asset Sale, if the aggregate amount of Excess Proceeds then exceeds $50.0 million, the Company shall commence an offer to all Holders of Notes (an “Asset Sale Offer”) pursuant to Section 3.04 of the Second Supplemental Indenture, and to all holders of any Pari Passu Indebtedness then outstanding, to purchase the maximum Reduced Principal Amount of Notes and such Pari Passu Indebtedness that may be purchased out of the

A - 4

Excess Proceeds, at an offer price in cash in an amount equal to 100% of the Reduced Principal Amount of the Notes plus accrued and unpaid interest, if any, thereon to the Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Settlement Date, in accordance with the procedures set forth in the Indenture. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate Reduced Principal Amount of Notes surrendered by Holders thereof and Pari Passu Indebtedness surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of Original Principal Amount of $1,000, or integral $1,000 multiples in excess thereof, shall be purchased) on the basis of the aggregate Original Principal Amount of tendered Notes and Pari Passu Indebtedness. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes.

8. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days (except as otherwise provided in the Indenture if the notice is issued in connection with a Discharge) before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations of Original Principal Amount of larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof called for redemption.

9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of Original Principal Amount of $1,000 and any integral multiple of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Company or the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and may require a Holder to pay any taxes due on transfer or exchange. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before the day of the mailing of a notice of redemption of Notes selected for redemption.

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

11. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture, the Notes or the Subsidiary Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate Reduced Principal Amount of the then outstanding Notes, and any existing default or compliance with any provision of the Indenture, the Notes or the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in aggregate Reduced Principal Amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture, the Notes or the Subsidiary Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes pursuant to Article 5 of

A - 5

the Second Supplemental Indenture, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, including any increase in the Conversion Rate or other consideration due upon conversion of the Notes (whether or not subject to time limitations or other conditions), as determined in accordance with Section 901 of the Original Indenture (as amended by Section 9.01 of the Second Supplemental Indenture), to secure the Notes or the Subsidiary Guarantees pursuant to Section 4.12 of the Second Supplemental Indenture or otherwise, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, to add any additional Guarantor with respect to the Notes or to evidence the release of any Guarantor from its Subsidiary Guarantee, in each case as provided in the Indenture, to comply with the requirements of Section 11.11 of the Second Supplemental Indenture, to evidence or provide for the acceptance of appointment under the Indenture of a successor Trustee, to add to, change or eliminate any provisions of the Indenture in respect of one or more other series of Securities or to establish the forms or terms of Securities of any other series as permitted by the Indenture, to make provision with respect to adjustments to the Conversion Rate as required by the Second Supplemental Indenture or to increase the Conversion Rate in accordance with the Second Supplemental Indenture or to make any changes necessary or advisable, in the Company’s sole discretion, in order to effect the settlement of amounts due pursuant to Section 4.01 of the Second Supplemental Indenture.

12. Defaults and Remedies. Events of Default with respect to the Notes include: (i) default for 30 days in the payment when due of interest on the Notes; (ii) default in payment when due of the Reduced Principal Amount of or premium, if any, on the Notes when due at Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; (iii) failure by the Company to comply with Section 4.07, 4.09, 4.10, 4.15 or 5.01 of the Second Supplemental Indenture; (iv) failure by the Company for 60 days after notice of such failure to the Company by the Trustee or the Holders of at least 25% in Reduced Principal Amount of the Notes then outstanding to comply with any of its other agreements in the Indenture or the Notes; (v) 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), whether such Indebtedness or guarantee now exists or is created after the Issue Date, if such default (a) is caused by a failure to pay principal of, or premium or interest, if any, on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness (a “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 in excess of $50.0 million or more; provided, that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default under the Indenture and any consequential acceleration of the Notes shall be automatically rescinded; (vi) failure by the Company or any of its Significant Subsidiaries to pay final judgments aggregating in excess of $50.0 million, which judgments are not paid, discharged or stayed (including a stay pending appeal) for a period of 60 days after the date of such final judgment (or, if later, the date when payment is due pursuant to such judgment); (vii) except as permitted by the Indenture, any Subsidiary Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases

A - 6

for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee (other than by reason of release of a Guarantor from its Subsidiary Guarantee in accordance with the terms of the Indenture); (viii) certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary as specified in Section 501(8) or 501(9) of the Original Indenture (as amended by Section 6.01 of the Second Supplemental Indenture) and (ix) failure by the Company to satisfy (a) its conversion or payment obligations in accordance with Article 11 of the Second Supplemental Indenture (x) upon a Holder’s exercise of its Early Conversion rights or (y) upon the Company’s exercise of its Mandatory Conversion rights, or (b) satisfy its distribution or payment obligations in accordance with Section 4.01 of the Second Supplemental Indenture upon any Reduction, which failure in each case is not cured within three Business Days; or the Company fails to comply with Section 4.22 of the Second Supplemental Indenture. If any Event of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in aggregate Reduced Principal Amount of the then outstanding Notes, by notice to the Company and the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the preceding, in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary described in Section 501(8) or 501(9) of the Original Indenture (as amended by Section 6.01 of the Second Supplemental Indenture), all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in Reduced Principal Amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power conferred on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default with respect to the Notes (except a Default or Event of Default relating to the payment of Reduced Principal Amount, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in Reduced Principal Amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any past Default or Event of Default with respect to the Notes and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the Reduced Principal Amount of or premium, if any, or interest on the Notes or conversion of the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and, so long as any Notes are outstanding, the Company is required upon becoming aware of any Default or Event of Default with respect to the Notes, to deliver to the Trustee a statement specifying such Default or Event of Default.

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

14. Subordination. The indebtedness evidenced by this Note is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Debt of the Company, and this Note is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Note, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes.

A - 7

15. Conversion and Reduction. The Notes shall be convertible into shares of Common Stock in accordance with Article 11 of the Second Supplemental Indenture. To convert a Note at its option, a Holder must satisfy the requirements of Section 11.02(a) of the Second Supplemental Indenture. A Holder may convert a portion of a Note in an Early Conversion if the portion is $1,000 Original Principal Amount or an integral multiple of $1,000 Original Principal Amount. The Notes are subject to Reduction in accordance with Section 4.01(c) of the Second Supplemental Indenture. Upon Reduction of the Notes, the Holders shall be entitled to receive shares of Common Stock in accordance with Section 4.01(d) of the Second Supplemental Indenture. The Notes are convertible at the Company’s option into shares of Common Stock in accordance with Section 11.01(c) of the Second Supplemental Indenture. Upon conversion of a Note pursuant to Early Conversion, the Holder thereof shall be entitled to receive the shares of Common Stock payable upon conversion in accordance with Article 11 of the Second Supplemental Indenture, at the Conversion Rate specified in the Second Supplemental Indenture, as adjusted from time to time as provided in the Second Supplemental Indenture.
