“Adjusted Consolidated Net Tangible Assets” or “ACNTA” means (without duplication), as of the date of determination, (a) the sum of (i) the discounted future net revenue from proved crude oil, natural gas and helium 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 increased by, as of the date of determination, the discounted future net revenue of (A) estimated proved crude oil, natural gas and helium reserves of the Company and its Restricted Subsidiaries attributable to acquisitions consummated since the date of such year-end reserve report, and (B) estimated crude oil, natural gas and helium reserves of the Company and its Restricted Subsidiaries attributable to extensions, discoveries and other additions and upward determinations of estimates of proved crude oil, natural gas and helium 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 which would, in the case of determinations made pursuant to clauses (A) and (B), in accordance with standard industry practice, result in such determinations, 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 (C) estimated proved crude oil, natural gas and helium 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 (D) reductions in the estimated crude oil, natural gas and helium 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, natural gas and helium reserves due to exploration, development or exploitation, production or other activities conducted or otherwise occurring since the date of such year-end reserve report which would, in the case of determinations made pursuant to clauses (C) and (D), in accordance with standard industry practice, result in such determinations, 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 (A) through (D), 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 which is an increase, then such increases and decreases in the discounted future net revenue shall be confirmed in writing by an independent petroleum engineer, (ii) the capitalized costs that are attributable to crude oil, natural gas and helium properties of the Company and its Restricted Subsidiaries to which no proved crude oil, natural gas and helium 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, (iii) the Net Working Capital on a date no earlier than the date of the Company’s latest annual or quarterly financial statements and (iv) 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 (provided that the Company shall not be required to obtain such an appraisal of such assets if no such appraisal has been performed), minus (b) to the extent not otherwise taken into account in the immediately preceding clause (a), the sum of (i) noncontrolling interests, (ii) any natural gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest audited financial statements, (iii) the discounted future net revenue, calculated in accordance with 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, (iv) 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 (v) 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 (a)(i) (utilizing the same prices utilized in the Company’s year-end reserve report), would be necessary to satisfy fully the obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified with respect thereto.

“Consolidated Coverage Ratio” as of any date of determination means the ratio of (i) the aggregate amount of EBITDA for the period of the most recent four consecutive fiscal quarters ending at least 45 days prior to the date of such determination to (ii) Consolidated Interest Expense for such four fiscal quarters; provided, however, that (1) if the Company or any Restricted Subsidiary has Incurred any Indebtedness since the beginning of such period that remains outstanding or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, or both, EBITDA and Consolidated Interest Expense for such period shall be calculated after giving effect on a pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period and the discharge of any other Indebtedness repaid, repurchased, defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on the first day of such period, (2) if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged on the date of the transaction giving rise to the need to calculate the Consolidated Coverage Ratio, EBITDA and Consolidated Interest Expense for such period shall be calculated on a pro forma basis as if such discharge had occurred on the first day of such period and as if the Company or such Restricted Subsidiary had not earned the interest income actually earned during such period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness, (3) if since the beginning of such period the Company or any Restricted Subsidiary shall have made any Asset Disposition (other than an Asset Disposition involving assets having a fair market value of less than the greater of (a) 2.5% of Adjusted Consolidated Net Tangible Assets as of the end of the Company’s then most recently completed fiscal year and (b) $3.0 million), then EBITDA for such period shall be reduced by an amount equal to EBITDA (if positive) directly attributable to the assets which are the subject of such Asset Disposition for such period, or increased by an amount equal to EBITDA (if negative) directly attributable thereto for such period, and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale), (4) if since the beginning of such period the Company or any Restricted Subsidiary (by merger or otherwise) shall have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or an acquisition (including by way of lease) of assets, including any acquisition of assets occurring in connection with a transaction requiring a calculation to be made hereunder, EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period and (5) if since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) shall have made any Asset Disposition, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (3) or (4) of this definition if made by the Company or a Restricted Subsidiary during such period, EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition occurred on the first day of such period. For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer of the Company. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into

ARTICLE 2

The Securities

Section 2.01Form and Dating. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or depository procedure or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The Securities will be governed by this Indenture and by the provisions relating to the Securities set forth in Appendix A hereto, which is hereby incorporated into and expressly made a part of this Indenture. The terms of the Securities set forth in Exhibit A are part of the terms of this Indenture.

Section 2.02Execution and Authentication. Two Officers shall sign the Securities for the Company by manual signature.

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

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

On the Issue Date, upon receipt of a written order of the Company signed by two Officers of the Company (a “Company Order”), the Trustee shall authenticate and deliver $84,650,000 of 3½% Convertible Senior Notes due 2024 and, at any time and from time to time thereafter, the Trustee shall, upon receipt of a Company Order, authenticate and deliver Securities for original issue in an aggregate principal amount specified in such Company Order; provided that, in each case, the Trustee shall be entitled to receive an Officers’ Certificate and an Opinion of Counsel of the Company that it may reasonably request in connection with such authentication of Securities. Such Company Order shall specify the amount of Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of an issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that such issuance is in compliance with this Indenture, including Sections 4.03 and 4.10 hereof.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

Section 2.03Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration or transfer or for exchange or conversion, which office shall maintain the names and addresses of Securityholders (the “Registrar”), and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange and conversion. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly-Owned Subsidiary incorporated or organized within the United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee as Registrar, Paying Agent and Conversion Agent in connection with the Securities.

Section 2.04Paying Agent To Hold Money in Trust. Prior to 11:00 a.m., New York City time, on each due date of (i) the principal and interest on any Security, (ii) any accrued and unpaid interest due upon any conversion, if applicable, or (iii) cash in lieu of fractional shares in connection with any conversion, the Company shall deposit with the Paying Agent a sum sufficient to pay such amounts

when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders and the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify in writing the Trustee of any default by the Company in making any such payment. If the Company or a Wholly-Owned Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee. Upon any Event of Default specified in Section 6.01 (7) or (8), the Trustee shall automatically serve as the Paying Agent for the Securities.

Section 2.05Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders.

Section 2.06Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer and in compliance with Appendix A. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met.

When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Company’s request. The Company may require the Securityholders to make a payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section. The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of any Securities between a regular record date and the next succeeding interest payment date.

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

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

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

Section 2.07Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee, upon the Company’s written instruction, shall authenticate and deliver a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar and in the judgment of the Trustee to protect the Trustee, the Paying Agent, the Registrar and any of the Trustee’s agents from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security.

Every replacement Security is an additional obligation of the Company.

Section 2.08Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) maturing, and the Paying Agent is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

Section 2.09Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate and deliver temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as definitive Securities.

Section 2.10Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment or cancellation. The Trustee and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and, following the Company’s written request, shall deliver a certificate of such destruction to the Company. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation.

Section 2.11Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the Persons who are Securityholders on a subsequent special record date as provided in the Securities and in Section 4.01 hereof. The Company shall fix or cause to be fixed any such special record date and payment date and shall promptly send to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

Section 2.12CUSIP Numbers and ISINs. The Company in issuing the Securities may use “CUSIP” numbers and/or “ISINs” (if then generally in use) and, if so, the Trustee shall use CUSIP numbers and/or ISINs in notices 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 Securities or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Securities, and any such notice shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP number or ISINs applicable to the Securities.

Section 2.13Issuance of Additional Securities. The Company shall be entitled, subject to its compliance with Sections 4.03 and 4.10, to issue Additional Securities under this Indenture which shall have identical terms as the Securities issued on the Issue Date, other than with respect to the date of issuance and issue price; provided that such Additional Securities are fungible with the Securities for U.S. federal income tax purposes or are issued under a separate CUSIP number and ISIN. The Securities issued on the Issue Date and any Additional Securities shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

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

(2)the issue price, the issue date and the CUSIP number and ISIN of such Additional Securities.

Section 2.14Designation of Securities. The Securities and the Subsidiary Guarantees shall constitute “Senior Indebtedness,” and the Company and the Subsidiary Guarantors hereby designate the Securities and the Subsidiary Guarantees as “Designated Senior Indebtedness” of the Company and the Subsidiary Guarantors, for purposes of the Existing Subordinated Notes Indentures. The Securities and the Subsidiary Guarantees shall be superior in right of payment to the Existing Subordinated Notes and the Guarantees thereof or any other Subordinated Obligations.

Section 2.15Shares of Common Stock Issued upon Conversion. Prior to the Resale Restriction Termination Date, all shares of Common Stock issued upon conversion of any Security shall bear, upon issuance, if reasonably determined by the Company that such shares are subject to restriction on transfer under the Securities Act at their time of issuance, the Common Stock Restricted Legend and be subject to the restrictions on transfer specified therein. Any shares of Common Stock that bear the Restricted Stock Legend and are subject to the restrictions on transfer specified therein and that have been transferred, replaced or exchanged on or after the Resale Restriction Termination Date or that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act may be exchanged for shares of Common Stock that do not bear the Restricted Stock Legend and are not subject to the restrictions on transfer specified therein in accordance with the procedures of the transfer agent for the Common Stock at such time, including delivery to such transfer agent of any additional documentation reasonably required by the Company or the transfer agent for Common Stock in connection with such exchange.

Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due and the Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Securityholders on that date pursuant to the terms of this Indenture.

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

(b)If and for so long as the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the information to be delivered pursuant to Section 4.02(a) shall not be required to (a) comply with (i) Section 302, 404 or 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 or related Items 307 and 308 of Regulation S-K promulgated by the SEC, (ii) Item 601 of Regulation S-K (with respect to exhibits) or (iii) Regulation G or Item 10(e) of Regulation S-K promulgated by the SEC with respect to any non-generally accepted accounting principles financial measures contained therein, (b) contain any separate financial statements, footnotes or other information contemplated by Rule 3-05, Rule 3-10 or Rule 3-16 or Article 11 of Regulation S-X promulgated by the SEC, (c) include financial statements in interactive data format using eXtensible Business Reporting Language or (d) present compensation or beneficial ownership information.

All current reports required under Section 4.02(a) shall be furnished within the time periods specified in the SEC’s rules and regulations for reporting companies under the Exchange Act. The Company shall make available such information and such reports to the Trustee under this Indenture, to any Holder and to any beneficial owner or potential purchaser of the Securities, in each case by posting such information on its website, Intralinks or any comparable freely accessible online data system, and shall make such information readily available to any prospective investor, any securities analyst or any Holder. For purposes of this Section 4.02(c), the Company shall be deemed to have furnished such reports and information to, or filed such reports and information with, the Trustee, the Holders of the Securities and to any beneficial owner or potential purchaser of the Securities as required by this Section 4.02(c) if it has filed such reports or information with the SEC via the ▇▇▇▇▇ filing system.

(e)Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of those materials will not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). It is understood that the Trustee shall have no obligation whatsoever to monitor or confirm, on a continuing basis or otherwise, the Company’s compliance with this Section 4.02, to determine whether or not such financial statements, information, documents or reports have been posted on any website or online data system or filed with the SEC or to participate in any conference calls.

(f)The Company may satisfy its obligations under Section 4.02(a) with respect to financial information relating to the Company by furnishing financial information relating to any parent entity of

Section 4.03Limitation on Indebtedness.

(a)The Company shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided, however, that the Company or a Restricted Subsidiary may Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto, the Consolidated Coverage Ratio equals or exceeds 2.25 to 1.0.

(2) Indebtedness owed to and held by the Company or any Restricted Subsidiary; provided, however, that any subsequent issuance or transfer of any Capital Stock which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to the Company or another Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness by the issuer thereof;

(3)

(A) any Second Lien Debt, any Junior Lien Debt and any unsecured Indebtedness in an aggregate principal amount outstanding, together with all other Indebtedness outstanding under this clause (b)(3)(A), not to exceed the greater of (x) $1,000.0 million and (y) (I) 65.0% of Modified ACNTA determined as of the date of such Incurrence minus (II) the aggregate amount of all Indebtedness outstanding under Credit Facilities Incurred under Section 4.03(b)(1) as of the date of such Incurrence (assuming for such purposes that all available amounts under Section 4.03(b)(1) are fully drawn); provided, however, that unsecured Indebtedness Incurred under this Section 4.03(b)(3)(A) after the Issue Date shall not have a Stated Maturity any earlier than the Stated Maturity of the Securities, and

(B) Indebtedness of the Company represented by the Securities (other than any Additional Securities);

such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company) and (B) the Company or a Restricted Subsidiary Incurred for the purpose of financing all or any part of the cost of acquiring Oil and Gas Properties or Carbon Dioxide Interests, another Person (other than a Person that was, immediately prior to such acquisition, a Subsidiary of the Company) engaged in the Oil and Gas Business or all or substantially all the assets of such a Person; provided, however, that in the case of each of clause (A) and clause (B) above, on the date of such Incurrence and after giving effect thereto, the Consolidated Coverage Ratio equals or exceeds 2.0 to 1.0;

(6) Refinancing Indebtedness in respect of Indebtedness Incurred pursuant to Section 4.03(a) or Section 4.03(b)(3)(B), (4) or (5), this clause (6) or clause (7) below; provided, however, that to the extent such Refinancing Indebtedness directly or indirectly Refinances Indebtedness or Preferred Stock of a Restricted Subsidiary described in Section 4.03(b)(5), such Refinancing Indebtedness shall be Incurred only by such Restricted Subsidiary or the Company;

(7) Non-recourse Purchase Money Indebtedness;

(c)Notwithstanding the foregoing, the Company shall not, and shall not permit any Subsidiary Guarantor to, Incur any Indebtedness pursuant to Section 4.03(b) if the proceeds thereof are

director stock option plan or other incentive plan, in a principal amount not to exceed the exercise price of such stock options or (B) to refinance loans, together with accrued interest thereon, made pursuant to item (A) of this clause (5); provided, however, that such loans shall be excluded in the calculation of the amount of Restricted Payments; (6) any Restricted Payment so long as on the date of such Restricted Payment, after giving pro forma effect thereto and to any related transactions as if the same had occurred at the beginning of the Company’s most recently ended four full fiscal quarters for which internal financial statements are available, the Company’s Leverage Ratio would not have exceeded 2.5 to 1.0; provided, however, that such Restricted Payment shall be excluded in the calculation of the amount of Restricted Payments; (7) other Restricted Payments in an aggregate amount not to exceed $100.0 million; provided, however, that such Restricted Payments shall be excluded in the calculation of the amount of Restricted Payments; or (8) any Restricted Payments in the form of purchases, repurchases, redemptions, defeasances or other acquisitions or retirements for value of the Existing Subordinated Notes in an aggregate amount of Restricted Payments on or after the Issue Date not to exceed $564.0 million; provided that such Restricted Payments shall be excluded in the calculation of the amount of Restricted Payments.

Section 4.06Limitation on Restrictions on Distributions from Restricted Subsidiaries. The Company shall not, and shall not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary (a) to pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness owed to the Company or a Restricted Subsidiary, (b) to make any loans or advances to the Company or a Restricted Subsidiary or (c) to transfer any of its property or assets to the Company or a Restricted Subsidiary, except: (i) any encumbrance or restriction in the Priority Lien Credit Agreement or Second Lien Documents on the Issue Date or pursuant to any other agreement in effect on the Issue Date; (ii) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement relating to any Indebtedness Incurred by such Restricted Subsidiary on or prior to the date on which such Restricted Subsidiary was acquired by the Company (other than Indebtedness Incurred as consideration in, or to provide all or any portion of the funds or credit support utilized to consummate, the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or was acquired by the Company) and outstanding on such date; (iii) any encumbrance or restriction pursuant to an agreement effecting a Refinancing of Indebtedness Incurred pursuant to an agreement referred to in clause (i) or (ii) of this Section 4.06 or this clause (iii) or contained in any amendment to an agreement referred to in clause (i) or (ii) of this Section 4.06 or this clause (iii); provided, however, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such refinancing agreement or amendment are no less favorable to the Securityholders than encumbrances and restrictions with respect to such Restricted Subsidiary contained in such agreements; (iv) any such encumbrance or restriction consisting of customary nonassignment provisions in leases governing leasehold interests to the extent such provisions restrict the transfer of the lease or the property leased thereunder; (v) in the case of clause (c) above, restrictions contained in security agreements or mortgages securing Indebtedness of a Restricted Subsidiary permitted to be Incurred pursuant to this Indenture to the extent such restrictions restrict the transfer of the property subject to such security agreements or mortgages; and (vi) any restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale or disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary in compliance with the terms of this Indenture pending the closing of such sale or disposition.

Section 4.07Limitation on Sales of Assets and Subsidiary Stock.

(a)The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Disposition unless (1) the Company or such Restricted Subsidiary

receives consideration at least equal to the fair market value (such fair market value to be determined in advance in good faith by an Officer or an officer of such Restricted Subsidiary with responsibility for such transaction, or if the Asset Disposition exceeds $50.0 million, by the Board of Directors, which determination shall be conclusive evidence of compliance with this provision), of the equity and assets subject to such Asset Disposition; (2) (A) at least 75% of the consideration received by the Company or such Restricted Subsidiary is in the form of cash or cash equivalents, Additional Assets or any combination thereof (collectively, the “Cash Consideration”) or (B) the fair market value of all forms of consideration other than Cash Consideration received by the Company and its Restricted Subsidiaries since September 30, 2017 does not exceed in the aggregate 10% of ACNTA at the time of the applicable Asset Disposition (after giving effect to such Asset Disposition); and (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company (or such Restricted Subsidiary, as the case may be) (A) first, to the extent the Company elects (or is required by the terms of any Indebtedness), to prepay, repay, redeem or purchase Senior Indebtedness of the Company or any Subsidiary Guarantor or Indebtedness (other than Disqualified Stock) of a Wholly-Owned Subsidiary that is not a Subsidiary Guarantor (other than Indebtedness owed to the Company or an Affiliate of the Company) within 540 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, provided such prepayment, repayment, redemption or purchase permanently retires, or reduces the related loan commitment (if any) for, such Indebtedness in an amount equal to the principal amount so prepaid, repaid, redeemed or purchased; (B) second, to the extent of the balance of such Net Available Cash after application in accordance with clause (A), to the extent the Company elects, to acquire Additional Assets or to make capital expenditures in the Oil and Gas Business within 540 days from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; and (C) third, to the extent of the balance of such Net Available Cash after application in accordance with clauses (A) and (B), to make an offer to the Holders (and to holders of other Senior Indebtedness of the Company designated by the Company) to purchase Securities (and such other Senior Indebtedness of the Company) pursuant to and subject to the conditions contained in this Indenture, which purchase permanently reduces the outstanding amount of such Securities (and such other Senior Indebtedness) in an amount equal to (or greater than) the principal amount purchased.

Pending application of Net Available Cash pursuant to this Section 4.07(a), such Net Available Cash shall be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit Indebtedness (which may include Priority Lien Debt).

(b)Notwithstanding Section 4.07(a), the Company and the Restricted Subsidiaries shall not be required to apply any Net Available Cash in accordance with Section 4.07(a) except to the extent that the aggregate Net Available Cash from all Asset Dispositions, which is not applied in accordance with Section 4.07(a), exceeds $40.0 million during any calendar year.

For the purposes of Section 4.07(a), the following are deemed to be cash or cash equivalents (i) any liabilities, as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Securities or any Subsidiary Guarantee) that are assumed by the transferee of any such Asset Disposition pursuant to (A) a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability or (B) an assignment agreement that includes, in lieu of such a release, the agreement of the transferee or its parent company to indemnify and hold harmless the Company or such Restricted Subsidiary from and against any loss, liability or cost in respect of such assumed liability and (ii) any non-Cash Consideration received by the Company or any Restricted Subsidiary from the transferee that is converted, monetized, sold or exchanged by the Company or such Restricted Subsidiary into cash or cash equivalents within 120 days of receipt. Notwithstanding the foregoing, the 75% limitation referred to in Section 4.07(a)(2) shall be deemed satisfied with respect to

any Asset Disposition in which the cash or cash equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Disposition complied with the aforementioned 75% limitation. The requirement of Section 4.07(a)(3)(B) shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to therein is entered into by the Company or its Restricted Subsidiary within the time period specified in such clause and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

(c)In the event of an Asset Disposition that requires the purchase of Securities (and other Senior Indebtedness of the Company) pursuant to Section 4.07(a)(3)(C), the Company shall make such offer to purchase Securities on or before the 541st day after the later of the date of such Asset Disposition or the receipt of such Net Available Cash, and shall purchase Securities tendered pursuant to an offer by the Company for the Securities (and if required or permitted by the terms of any other Senior Indebtedness, to the holders of such Indebtedness) at a purchase price of 100% of their principal amount (or, in the event (x) such other Senior Indebtedness (other than the Existing 2021 Second Lien Notes, the New 2022 Second Lien Notes or the other series of convertible notes) of the Company was issued with original issue discount greater than 2.5%, and (y) the Existing 2021 Second Lien Notes are outstanding, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest (or, in respect of such other Senior Indebtedness of the Company, such lesser price, if any, as may be provided for by the terms of such Senior Indebtedness of the Company) in accordance with the procedures (including prorating in the event of oversubscription) set forth in Section 3.02; provided, however, that if the terms of an asset sale covenant relating to Secured Debt outstanding as of the Issue Date would require that such Secured Debt be included in an offer hereunder for the Securities, and the terms of such Secured Debt require that the price offered for the Securities in such offer be at a price not greater than 100% of accreted value, the Company may make the offer for the Securities hereunder at a price of 100% of accreted value so long as the Company has previously made an offer with the then remaining Net Available Cash from the applicable Asset Disposition for the Securities under Section 4.07(a)(3)(A) or otherwise at a price of 100% of principal amount.. If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their purchase, the Company shall select the securities to be purchased on a pro rata basis but in round denominations, which in the case of the Securities shall be minimum denominations of $2,000 principal amount and whole multiples of $1,000 in excess thereof. The Company shall not be required to make such an offer to purchase Securities (and other Senior Indebtedness of the Company) pursuant to this Section 4.07 if the Net Available Cash not applied or invested as provided in Section 4.07(a)(3)(A) or (B) is less than $20.0 million (which lesser amount shall be carried forward for purposes of determining whether such an offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an offer to purchase, Net Available Cash shall be deemed to be reduced by the aggregate amount of such offer.

(d)The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to Section 4.07(c). To the extent that the provisions of any securities laws or regulations conflict with provisions of Section 4.07(c), the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under Section 4.07(c) by virtue of its compliance with such securities laws or regulations.

Section 4.08Limitation on Affiliate Transactions.

(a)The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with any Affiliate of the Company (an “Affiliate Transaction”) unless the terms thereof (1) are no less favorable to the Company or such Restricted Subsidiary than those that could be obtained at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate, (2) if such Affiliate Transaction involves an amount in excess of $15.0 million, are set forth in writing and have been approved by the Board of Directors, including a majority of the members of the Board of Directors having no personal stake in such Affiliate Transaction, and (3) if such Affiliate Transaction involves an amount in excess of $25.0 million, have been determined by a nationally recognized investment banking or accounting firm or other qualified independent appraiser to be fair, from a financial standpoint, to the Company and its Restricted Subsidiaries.

(b)The provisions of Section 4.08(a) shall not prohibit (i) any sale of hydrocarbons or other mineral products to an Affiliate of the Company or the entering into or performance of Oil and Gas Hedging Contracts, gas gathering, transportation or processing contracts or oil or natural gas marketing or exchange contracts with an Affiliate of the Company, in each case, in the ordinary course of business, so long as the terms of any such transaction are approved by a majority of the members of the Board of Directors who are disinterested with respect to such transaction, (ii) the sale to an Affiliate of the Company of Capital Stock of the Company that does not constitute Disqualified Stock, and the sale to an Affiliate of the Company of Indebtedness (including Disqualified Stock) of the Company in connection with an offering of such Indebtedness in a market transaction and on terms substantially identical to those of other purchasers in such market transaction, (iii) transactions contemplated by any employment agreement or other compensation plan or arrangement existing on the Issue Date or thereafter entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business, (iv) the payment of reasonable fees to directors of the Company and its Restricted Subsidiaries who are not employees of the Company or any Restricted Subsidiary, (v) transactions between or among the Company and its Restricted Subsidiaries, (vi) transactions between the Company or any of its Restricted Subsidiaries and Persons that are controlled (as defined in the definition of “Affiliate”) by the Company (an “Unrestricted Affiliate”); provided that no other Person that controls (as so defined) or is under common control with the Company holds any Investments in such Unrestricted Affiliate; (vii) Restricted Payments that are permitted by the provisions of Section 4.05; and (viii) loans or advances to employees in the ordinary course of business and approved by the Company’s Board of Directors in an aggregate principal amount not to exceed $2.5 million outstanding at any one time.

Section 4.09Change of Control.

(a)Upon the occurrence of a Change of Control, each Holder shall have the right to require that the Company purchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment date occurring on or prior to the purchase date), in accordance with the terms contemplated in Section 4.09(b). In the event that at the time of such Change of Control the terms of the Indebtedness under the Priority Lien Credit Agreement restrict or prohibit the repurchase of Securities pursuant to this Section, then prior to the mailing or other delivery in accordance with the applicable procedures of DTC of the notice to Holders provided for in Section 4.09(b), but in any event within 30 days following any Change of Control, the Company shall (i) repay in full the Indebtedness under the Priority Lien Credit Agreement

or (ii) obtain the requisite consent under the agreements governing the Indebtedness under the Priority Lien Credit Agreement to permit the repurchase of the Securities as provided for in Section 4.09(b).

(b)Within 30 days following a Change of Control, the Company shall mail, or otherwise deliver in accordance with the applicable procedures of DTC, a notice to each Holder with a copy to the Trustee stating: (1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment date occurring on or prior to the purchase date); (2) the circumstances and relevant facts regarding such Change of Control (including information with respect to pro forma historical income, cash flow and capitalization, in each case after giving effect to such Change of Control); (3) the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed or otherwise delivered in accordance with the applicable procedures of DTC); and (4) the instructions determined by the Company, consistent with this Section 4.09, that a Holder must follow in order to have its Securities purchased.

(c)Holders electing to have a Security purchased shall be required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Trustee or the Company receives not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and a statement that such ▇▇▇▇▇▇ is withdrawing his election to have such Security purchased.

(d)On the purchase date, all Securities purchased by the Company under this Section shall be delivered to the Trustee for cancellation, together with an Officers’ Certificate to confirm the purchase and directing the Trustee to cancel such Securities, and the Company shall pay the purchase price plus accrued and unpaid interest, if any, to the Holders entitled thereto.

(e)The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.09. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.09, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.09 by virtue thereof.

(f)The Company shall not be required to make an offer to purchase Securities as a result of a Change of Control pursuant to this Section 4.09 if a third party (i) makes such offer in the manner, at the times and otherwise in compliance with the requirements set forth in Section 4.09(b) and (ii) purchases all Securities validly tendered and not withdrawn under such an offer.

Section 4.10Limitation on Liens. The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, enter into, create, incur, assume or suffer to exist any Lien (other than Permitted Liens) on or with respect to any property of the Company or such Restricted Subsidiary, whether owned on the Issue Date or acquired after the Issue Date, or any interest therein or any income or profits therefrom, unless the Securities or any Subsidiary Guarantee of such Restricted Subsidiary, as applicable, are secured equally and ratably with (or prior to) any and all other Indebtedness secured by such ▇▇▇▇, except that if such Indebtedness is subordinated in right of payment, the Lien securing the Securities will be senior in priority to such Lien.

Section 4.11Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year (beginning with the fiscal year ending December 31, 2017) of the Company an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such fiscal year. If they do, the certificate shall describe the Default, its status and what action the Company is taking or proposes to take with respect thereto. The Company also shall comply with Section 314(a)(4) of the TIA.

Section 4.12Further Instruments and Acts. Upon request of the Trustee, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

Section 4.13Future Subsidiary Guarantors. The Company shall cause each “100% owned” (within the meaning of Rule 3-10(h)(1) of Regulation S-X) domestic Restricted Subsidiary that represents 10% or more of the book assets of, or 10% or more of the ACNTA of, the Company and its Restricted Subsidiaries, taken as a whole, or that Guarantees or otherwise has an aggregate of $15.0 million or more of Indebtedness or Preferred Stock outstanding at any time to promptly Guarantee the Securities pursuant to a Supplemental Indenture substantially in the form attached hereto as Exhibit 1.

Section 4.14Suspension of Certain Covenants.

(a)If at any time after the Issue Date: (i) the Securities have Investment Grade Ratings from both Rating Agencies and (ii) no Event of Default has occurred and is continuing under this Indenture at such time (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), then until the end of the Suspension Period (as defined in Section 4.14(b)) the Company and the Restricted Subsidiaries shall not be subject to the provisions under Sections 4.03, 4.04, 4.05 (provided that no Restricted Subsidiary may be designated as an Unrestricted Subsidiary during the Suspension Period), 4.06, 4.07, 4.08, and paragraph (iv) of Section 5.01 (collectively, the “Suspended Covenants”).

(b)In the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraws its Investment Grade Rating or downgrades the rating assigned to the Securities below an Investment Grade Rating, then the Company and the Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants with respect to future events. Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default shall be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during the period of time between the Covenant Suspension Event and the Reversion Date (the “Suspension Period”), or upon termination of the Suspension Period or after that time based on any actions taken by the Company or its Restricted Subsidiaries during the Suspension Period. On the Reversion Date, all Indebtedness incurred during the Suspension Period shall be classified as having been incurred pursuant to Section 4.03(a) or Section 4.03(b) (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be incurred pursuant to Section 4.03(a) or Section 4.03(b), such Indebtedness shall be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.03(b)(4). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.05 shall be made as though Section 4.05 had been in effect since the Issue Date and throughout the Suspension Period. Accordingly, Restricted Payments

made during the Suspension Period shall reduce the amount available to be made as Restricted Payments under Section 4.05(a)(3) except to the extent that such Restricted Payments were permitted to have been made and are treated as having been made pursuant to Section 4.05(b).

(c)The Company shall promptly notify the Trustee in an Officers’ Certificate of the existence, and of the termination, of any Covenant Suspension Event or Reversion Date; provided, however, that the Trustee shall have no obligation to (i) monitor the ratings of the Securities, (ii) discover or verify the existence or termination of any Covenant Suspension Event or Reversion Date or (iii) notify holders of the Securities of any of the foregoing.

Section 4.15Registration Rights; Additional Interest.

(a)The Company shall: (i) file with the SEC a shelf registration statement (the “Registration Statement”) (which shall be an automatic shelf registration statement if the Company is then a well-known seasoned issuer as defined in Rule 405 under the Securities Act) with the SEC and cause such shelf registration statement to become effective on or prior to the 30th day after the Issue Date covering resales of the shares of Common Stock issuable upon conversion of the Securities; and (ii) keep such shelf registration statement effective until the earliest of: (1) the 20th Trading Day immediately following the Stated Maturity of the Securities, (2) the date on which there are no longer any Securities or ‘‘restricted’’ (within the meaning of Rule 144) shares of Common Stock outstanding that have been issued upon conversion of the Securities and (3) the date on which all Common Stock issuable upon conversion of the Securities is eligible for sale and transfer without registration under the Securities Act pursuant to Rule 144 thereunder (without limitations on volume or manner of sale pursuant to Rule 144) by Holders other than the Company’s affiliates (or Holders that were the Company’s affiliates at any time during the three months immediately preceding).

If the Company is not in compliance with the foregoing sentence at any time, the Company shall pay additional interest on the Securities at a rate equal to 0.50% per annum of the aggregate principal amount of the Securities then outstanding for each day for which the Company’s noncompliance occurred and is continuing.

The use and availability of the Registration Statement and related prospectus by any Holder or beneficial holder for resales of shares of Common Stock issuable upon conversion of the Securities is subject to the Company’s receipt of a properly completed Selling Holder Notice and Questionnaire (or such disclosure as may be required to be included in the Registration Statement and related prospectus with respect to the beneficial holder being named as a selling stockholder, together with such information and acknowledgements related thereto as are reasonably satisfactory to the Company), the beneficial holder being named as a selling stockholder in the Registration Statement and related prospectus, whether by post-effective amendment, supplement, incorporation by reference or otherwise, to the extent required by and in accordance with applicable law, and the beneficial holder’s compliance with the representations and warranties contained in Item (10) of the Selling Holder Notice and Questionnaire and the other terms and conditions thereof.

(b)If, at any time during the six-month period beginning on, and including, the date that is six months after the Issue Date, the Company fails to timely file any document or report that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), as applicable, or the Securities are not otherwise freely tradable by Holders other than the Company’s affiliates (as a result of restrictions pursuant to U.S. securities law or the terms of the Indenture or the Securities), the Company shall pay additional interest on the Securities at a rate equal to 0.50% per annum of the aggregate principal amount

of the Securities then outstanding for each day during such six-month period for which the Company’s failure to file has occurred and is continuing.

(c)If, at any time on or after the 365th day after the Issue Date: (i) there is a restrictive legend on the Securities, (ii) the Securities are assigned a restricted CUSIP number, or (iii) the Securities are not otherwise freely tradable pursuant to Rule 144 without restrictions by Holders other than the Company’s affiliates (as a result of restrictions pursuant to U.S. securities law or the terms of the Indenture or the Securities) (each a “restricted event”), the Company shall pay additional interest on the Securities at a rate equal to 0.50% per annum of the aggregate principal amount of the Securities then outstanding for each day on or after the 365th day after the Issue Date on which such restricted event is continuing.

(d)Any additional interest rate on the Securities pursuant to this Section 4.15 shall not exceed 0.50% per annum in the aggregate and shall not be payable under more than one such clause above for any period of time. Additional interest payable as a result of this section shall be payable in arrears on each interest payment date following accrual in the same manner as regular interest on the Securities. The obligation to pay additional interest pursuant to this Section 4.15 shall be the sole remedy for non-compliance with Section 4.15(a) and (c).

ARTICLE 6

Defaults and Remedies

Section 6.01Events of Default. An “Event of Default” occurs if:

(1)the Company defaults in any payment of interest on any Security when the same becomes due and payable and such default continues for a period of 30 consecutive days;

(2)the Company (i) defaults in the payment of the principal of any Security when the same becomes due and payable at its Stated Maturity, upon required purchase, upon

declaration of acceleration or otherwise or (ii) fails to redeem or purchase Securities when required pursuant to this Indenture or the Securities;

(3)the Company fails to comply with Section 5.01;

(4)the Company fails to comply with Section 4.02, 4.03, 4.04, 4.05, 4.06, 4.07 (other than a failure to purchase Securities when required under Section 4.07), 4.08, 4.09 (other than a failure to purchase Securities when required under Section 4.09), 4.10 or 4.11 and such failure continues for 30 consecutive days after the notice specified below;

(5)the Company or any Restricted Subsidiary fails to comply with any of its agreements contained in the Securities (other than those referred to in (1), (2), (3) or (4) above) and such failure continues for 60 consecutive days after the notice specified below;

(6)Indebtedness of the Company (other than Non-recourse Purchase Money Indebtedness) is not paid within any applicable grace period after final maturity or the maturity of such Indebtedness is accelerated by the holders thereof because of a default (and such acceleration is not rescinded or annulled) and the total amount of such Indebtedness unpaid or accelerated exceeds $75.0 million;

(7)the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(A) commences a voluntary case;

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

(D) makes a general assignment for the benefit of its creditors;

or takes any comparable action under any foreign laws relating to insolvency;

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

(A) is for relief against the Company or any Significant Subsidiary in an involuntary case;

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

or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days;

(9)any judgment or decree for the payment of money in an uninsured or unindemnified amount in excess of $75.0 million or its foreign currency equivalent at the time is rendered against the Company or a Significant Subsidiary and is not discharged and either (A) an enforcement proceeding has been commenced by any creditor upon such judgment or decree or (B) there is a period of 60 days following the entry of such judgment or decree during which such judgment or decree is not discharged, waived, bonded or the execution thereof stayed, in either case 10 days after the notice specified below;

(10)any Subsidiary Guarantee ceases or otherwise fails to be in full force and effect (other than in accordance with the terms of such Subsidiary Guarantee) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee if such default continues for a period of 10 days after the notice specified below; or

(11)the Company fails to satisfy its conversion or payment obligations in accordance with Article 10, which failure is not cured within five (5) Business Days.

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

The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

A Default under clause (4), (5), (9) or (10) is not an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the Securities notify the Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”

The Company shall deliver to the Trustee, within 30 days after the occurrence thereof, written notice, in the form of an Officers’ Certificate, of any Event of Default under clause (3) or (6) of this Section 6.01 and any event which with the giving of notice or the lapse of time would become an Event of Default under clause (4), (5), (9) or (10) of this Section 6.01, describing its status and what action the Company is taking or proposes to take with respect thereto. The Trustee shall not be deemed to have knowledge of any Default or Event of Default unless one of its Trust Officers receives written notice thereof from the Company or any of the Holders and such notice shall specify the Default and refer to this Indenture or the Securities.

Section 6.02Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(7) or (8) with respect to the Company) occurs and is continuing, the Trustee by written notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by written notice to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(7) or (8) with respect to the Company occurs and is continuing, the principal of and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. Any such amount hereby constitutes liquidated damages reasonably agreed by the Company and the Holders in view of the impracticability of determining actual damages. The Holders of a majority in principal amount of the outstanding Securities by written notice to the Trustee and the Company may rescind any acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived

except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

Section 6.03Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

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

Section 6.04Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities by written notice to the Trustee may waive an existing or past Default and its consequences except (i) a Default in the payment of the principal of or interest on a Security or settlement due upon the conversion of any Security or (ii) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

Section 6.05Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law, this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other Securityholder or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to be furnished with indemnification satisfactory to it in its sole discretion against all losses, liabilities and expenses caused by taking or not taking such action.

Section 6.06Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

(1)the Holder gives to the Trustee written notice stating that an Event of Default is continuing;

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

(3)such Holder or Holders furnish, if required by the Trustee, to the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

(4)the Trustee does not comply with the request within 60 days after receipt of the request and the furnishing of the required security or indemnity; and

(5)the Holders of a majority in principal amount of the outstanding Securities do not give the Trustee a direction inconsistent with the request during such 60-day period.

A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder.

Section 6.07Rights of Holders To Receive Payment. Notwithstanding any other provision of this Indenture, the contractual right of any Holder to receive payment of principal of, premium (if any) or interest on the Securities held by such Holder, or to receive payment of any consideration due upon conversion of the Securities held by such Holder, on or after the respective due dates expressed in the Securities, shall not be impaired or affected without the consent of such Holder, and the right of any Holder to bring suit for the enforcement of any such payment on or after such respective dates shall not be impaired or affected without the consent of such Holder.

Section 6.08Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company and the Subsidiary Guarantors for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

Section 6.09Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Securityholders allowed in any judicial proceedings relative to the Company or any Subsidiary Guarantor their respective creditors or their respective property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07.

Section 6.10Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

FIRST: to the Trustee for amounts due under Section 7.07;

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

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

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

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

Section 6.12Waiver of Stay or Extension Laws

. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this 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 shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE 7

Trustee

Section 7.01Duties of Trustee.

(a)If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

(b)Except during the continuance of an Event of Default:

(1)the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2)in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein).

(f)Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g)No provision of this Indenture shall require the Trustee to advance, expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(h)Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01.

(i)Notwithstanding anything to the contrary herein, the Trustee shall have no duty to review the reports and information documents required to be provided by Section 4.02 for the purposes of determining compliance with any provisions of this Indenture.

Section 7.02Rights of Trustee.

(a)The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

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

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

(f)In no event shall the Trustee be liable to any Person for punitive damages.

(g)The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder.

(h)The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the losses, liabilities and expenses which may be incurred therein or thereby.

(i)The Trustee may request that the Company delivers an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

(j)Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by one Officer of the Company.

(k)The permissive rights of the Trustee enumerated hereunder shall not be construed as duties.

Section 7.03Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent, co-registrar, co-paying agent or co-conversion agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

Section 7.04Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

Section 7.05Notice of Defaults. If a Default occurs and is continuing and (i) a Trust Officer has actual knowledge of such Default or (ii) written notice of such Default is given to the Trustee by the Company or Holders of at least 25% in aggregate principal amount of the Securities and such notice references the Securities and this Indenture, the Trustee shall mail or otherwise deliver in accordance with the applicable procedures of DTC to each Securityholder notice of the Default within the later of (i) 90 days after it occurs and (ii) 10 Business Days after such actual knowledge or written notice. Except in the case of a Default in payment of principal of or interest on any Security (including payments pursuant to the mandatory redemption provisions of such Security, if any), the Trustee may withhold the notice if and so long as the Trust Officer responsible for administering this Indenture and the Securities in good faith determines that withholding notice is not opposed to the interests of Securityholders.

Section 7.06[Reserved].

Section 7.07Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its services, including extraordinary services such as default administration. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee and its officers, directors, employees and agents against any and all loss, liability or expense (including attorneys’ fees) arising out of its acceptance of this trust or incurred by any of them in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture against the Company (including under this Section 7.07). The Trustee shall notify the Company promptly of any claim (whether asserted by any Securityholder or the Company) for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, gross negligence or bad faith as determined by a final, non-appealable judgment of a court of competent jurisdiction.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

The Company’s obligations pursuant to this Section and immunities of the Trustee contained in this Section shall survive the resignation or removal of the Trustee and the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or (8) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

Section 7.08Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount outstanding of the Securities may remove the Trustee upon 30 days written notice to the Trustee and may appoint a successor Trustee. A Holder may petition a court of competent jurisdiction to remove the Trustee in the manner and under the circumstances contemplated by Section 310(b)(iii) of the TIA. The Company shall remove the Trustee if:

(1)the Trustee fails to comply with Section 7.10;

(2)the Trustee is adjudged bankrupt or insolvent;

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

(4)the Trustee otherwise becomes incapable of acting.

If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount outstanding of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

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

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount outstanding of the Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

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

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

Upon satisfaction of the conditions set forth in this Section 8.01, the Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company.

(b)Notwithstanding Section 8.01(a), the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.07, 7.07, 7.08 and this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive.

Section 8.02Application of Trust Money. The Trustee shall hold in trust money, U.S. Government Obligations pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities and to the conversion of the Securities as applicable.

ARTICLE 9

(7)to make any change that does not adversely affect the rights of any Holder in any material respect, including any increase in the Conversion Rate or other consideration due upon conversion of the Securities (whether or not subject to time limitations or other conditions); provided, however, that any change to this Indenture to conform it to the Description of Convertible Notes shall not be deemed to adversely affect such rights;

(8)to conform the text of this Indenture or the Subsidiary Guarantees to any provision in the Description of Convertible Notes to the extent that such text constitutes an unintended conflict with, or is inconsistent with, the description of the corresponding provision in the Description of Convertible Notes, in each case as described in an Officers’ Certificate;

(9)to make provision with respect to adjustments to the Conversion Rate (and corresponding adjustments to the Threshold Price) as required by this Indenture or to increase the Conversion Rate (and therefore decrease the Threshold Price) in accordance with this Indenture; or

(10)to change the right to convert the Securities into Reference Property in the case of a Merger Event and in accordance with Section 10.11.

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

Section 9.02With Consent of Holders. Subject to other exceptions set forth in this Indenture, the Company, the Subsidiary Guarantors and the Trustee may amend any of this Indenture or the Securities without prior notice to any Securityholder but with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities). Without the consent of each Securityholder affected thereby, however, an amendment may not:

(1)reduce the amount of Securities whose Holders must consent to an amendment;

(2)reduce the rate of or extend the time for payment of interest on any Security;

(3)reduce the principal of or extend the Stated Maturity of any Security;

(4)reduce the premium payable upon a required purchase (to the extent the Company has at the time become obligated by the terms of this Indenture to effect a required purchase);

(5)make any Security payable in money other than that stated in the Security;

(8)make any change in any Subsidiary Guarantee that could adversely affect such Securityholder; or

(9)reduce the consideration due upon conversion or otherwise adversely affect the right of Holders to convert securities in accordance with Article 10, or impair the right of any Holder to institute suit for the enforcement of any payment of consideration due upon conversion of such Holder’s Securities.

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

Section 9.03[Reserved].

Section 9.04Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder shall bind the Holder and every subsequent Holder or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

Section 9.05Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Company may require the Holder to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

Section 9.06Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture and that such amendment is the legal, valid and binding obligation of the Company and any Subsidiary Guarantor, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof.

Section 9.07Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid or agreed to be paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

ARTICLE 10

Conversion

Section 10.01Conversion.

(a)Subject to compliance with Section 10.02, a Holder shall have the right to convert all or any portion (if such portion is $1,000 principal amount or an integral multiple of $1,000 principal amount) of its Securities (“Optional Conversion”), at any time from the date of issuance until the Close of Business on the Business Day immediately preceding the maturity date of the Securities, into a number of shares of Common Stock per $1,000 principal amount of Securities being converted equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares of Common Stock in accordance with Section 10.03).

(b)The Company shall convert the Securities (“Mandatory Conversion”) into a number of shares of Common Stock per $1,000 principal amount of Securities equal to the Conversion Rate then in effect (plus cash in lieu of fractional shares of Common Stock in accordance with Section 10.03), if the Daily VWAP of the Common Stock (or other security into which the Securities are convertible pursuant to Section 10.11) exceeds the Threshold Price in effect for at least 10 Trading Days (whether or not consecutive) during any period of 15 consecutive Trading Days (the “Mandatory Conversion Event”). Upon the occurrence of the Mandatory Conversion Event, the Company shall deliver notice to the Holders of the Securities, the Trustee and the Conversion Agent (if other than the Trustee) (such notice, a “Mandatory Conversion Notice”) not later than the Open of Business on the second Business Day following the Mandatory Conversion Event, which notice shall specify the date on which the Mandatory Conversion shall occur, which shall not be later than the fifth Business Day following the notice of the Mandatory Conversion Event (the “Mandatory Conversion Date”).

Notwithstanding the foregoing, a Mandatory Conversion shall not occur unless, as evidenced by an Officers’ Certificate delivered to the Trustee and the Conversion Agent (if other than the Trustee) on the Mandatory Conversion Date, 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 Mandatory Conversion Notice and (y) ending on, and including, the Mandatory Conversion Date (the “Equity Conditions Measuring Period”):

(i)either (1) all shares of Common Stock issuable upon conversion of the Securities 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 Securities shall have 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 Mandatory Conversion Date until a date that is at least thirty days following the Mandatory Conversion Date;

(ii)the Common Stock deliverable upon conversion is listed or traded on The New York Stock Exchange, The NASDAQ Global Select Market, The NASDAQ Global 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 the Mandatory Conversion Date, for any Securities validly surrendered for Optional Conversion on or prior to the date of the Mandatory Conversion Notice 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 those Securities to the applicable Holders in accordance with Section 10.01(a);

(iv)any shares of Common Stock to be issued upon conversion may be issued 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 or are then listed or trading; and

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

The Company shall use its reasonable best efforts to keep the registration statement described under Section 10.01(b)(i) above effective and available for use for at least 30 days following the Mandatory Conversion Date.

(c)Interest shall cease to accrue on any Securities on the applicable Conversion Date.

(d)If a Holder exercises its right to require the Company to repurchase its Securities in connection with the occurrence of a Change of Control in accordance with Section 4.09, such Holder may convert its Securities into Common Stock only if it withdraws its election to have its Securities repurchased in connection with such Change of Control and converts its Securities prior to the Close of Business on the Business Day immediately preceding the applicable repurchase date.

Section 10.02Conversion Procedure and Payment Upon Conversion.

(a)To convert its Security pursuant to an Optional Conversion, a Securityholder must:

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

(ii)surrender the Security to the Conversion Agent;

(iii)furnish appropriate endorsements and transfer documents if required by the Registrar, Conversion Agent or the Company’s transfer agent; and

(iv)pay all transfer or similar taxes if required pursuant to Section 10.04.

If a Holder holds a beneficial interest in a Global Security, to convert such Security, the Holder must comply with clause (iv) above and DTC’s applicable procedures for converting a beneficial interest in a Global Security.

(b)In connection with an Optional Conversion or a Mandatory Conversion, the Company shall deliver to each converting Holder, through the Company’s transfer agent, a number of shares of Common Stock per $1,000 principal amount of Securities being converted equal to the Conversion Rate in effect on the applicable Conversion Date (plus cash in lieu of fractional shares, if applicable, in accordance with Section 10.03). In addition, the Company shall deliver, through the Conversion Agent, with respect to the Securities being converted, cash in an amount per $1,000 principal amount of Securities equal to accrued and unpaid interest to, but not including, the Conversion Date; provided, that if the Conversion Date occurs during the period after the Close of Business on any regular record date and before the opening of business on the corresponding interest payment date, notwithstanding such conversion, the full amount of interest payable with respect to the Securities will be payable on such interest payment date to the Holders in whose names the Securities are registered at the Close of Business on such regular record date and accrued interest will not be paid to the converting Holder. The shares of Common Stock issuable upon conversion of a Global Security shall be delivered by the Company in accordance with DTC’s applicable procedures; provided, that, prior to the Resale Restriction Termination Date, if the Company reasonably determines that the shares of Common Stock are subject to restriction on transfer under the Securities Act at their time of issuance, they shall be issued in a form bearing the Common Stock Restricted Legend and subject to the restrictions on transfer specified therein.

(c)Securities surrendered for conversion will be deemed converted at the Close of Business on the applicable Conversion Date, and the Person in whose name the shares of Common Stock shall be issued upon such conversion shall become the holder of record of such shares as of the Close of Business on such Conversion Date. Prior to the Close of Business on such Conversion Date, 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 Security pursuant hereto, all rights of the Holder of such Security shall terminate, other than the right to receive the consideration deliverable or payable upon conversion of such Security as provided in Section 10.02(b). Settlement of any conversion provided for in this Article 10 shall occur (i) on the second Business Day immediately following the Optional Conversion Date, in the case of an Optional Conversion and (ii) on the Mandatory Conversion Date, in the case of a Mandatory Conversion.

(d)Upon surrender of a Security that is converted in part, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unconverted portion of the Security surrendered.

Section 10.03Cash in Lieu of Fractional Shares. The Company will not issue a fractional share of Common Stock upon conversion of a Security. 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 10.04Taxes 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 Security. However, the converting Holder shall pay any such tax or duty that becomes due because such shares are issued in a name other than such ▇▇▇▇▇▇’s name. The Company’s transfer agent may refuse to deliver a certificate representing the Common Stock to be issued in a name other than such ▇▇▇▇▇▇’s name until the Company’s transfer agent receives a sum sufficient to pay any tax or duty which will become due because such shares are to be issued in a name other than such ▇▇▇▇▇▇’s name.

Section 10.05Company to Reserve, Provide and List Common Stock.

(a)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 conversion, in accordance herewith, of all of the Securities outstanding.

(b)All shares of Common Stock issued upon conversion of the Securities 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.

(c)The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities 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 Conversion Date.

Section 10.06Adjustment 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 solely shares of Common Stock as a dividend or distribution on all or substantially all of the shares of its Common Stock, or if the Company subdivides or combines the Common Stock, the Conversion Rate will 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 the Open of Business on the effective date of such subdivision or combination of Common Stock, 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 subdivision or combination of Common Stock, as the case may be;

OS₀ = the number of shares of the Company’s 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 subdivision or combination of Common Stock, as the case may be; and

OS = the number of shares of the Company’s Common Stock that would be outstanding immediately after giving effect to such dividend or distribution, or immediately after the effective date of such subdivision or combination of Common Stock, as the case may be.

Any adjustment made under this Section 10.06(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 of such subdivision or combination of Common Stock, as the case may be. If such dividend, distribution, subdivision or combination described in this Section 10.06(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Company’s board of directors or a duly authorized committee thereof determines not to pay such dividend

or distribution or to effect such subdivision or combination, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared or subdivision or combination had not been announced.

(b)If an ex-dividend date occurs for a distribution to all or substantially all holders of the Company’s Common Stock of any rights, options or warrants entitling them for a period of not more than 60 calendar days from the announcement date for such distribution to subscribe for or purchase shares of the Company’s Common Stock, at a price per share less than the average of the Closing Sale Prices of the Company’s Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution, the Conversion Rate will be increased based on the following formula:



CR = CR₀ ×	OS₀+ X
	OS₀+ Y

where,

CR₀ = the Conversion Rate in effect immediately prior to the Close of Business on the record date for such distribution;

CR = the Conversion Rate in effect immediately after the Close of Business on the record date for such distribution;

OS₀ = the number of shares of Common Stock outstanding immediately prior to Close of Business on the record date for such distribution;

X = the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y = the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the announcement date for such distribution.

Any increase made under this Section 10.06(b) will be made successively whenever any such rights, options or warrants are issued and will become effective immediately after the Close of Business on the record date for such distribution. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if the record date for such distribution had not occurred.

For purposes of this Section 10.06(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at a price that is less than the average of the Closing Sale Prices of the Company’s Common Stock for each Trading Day in the applicable 10 consecutive Trading Day period, there shall be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise thereof, with the value

of such consideration if other than cash to be determined in good faith by the Company’s board of directors or a duly authorized committee thereof.

(c)If an ex-dividend date occurs for a distribution of shares of the Company’s capital stock, evidences of the Company’s indebtedness or other assets or property of the Company or rights, options or warrants to acquire the Company’s capital stock or other securities, to all or substantially all holders of the Company’s Common Stock (excluding (i) dividends or distributions and rights, options or warrants as to which an adjustment was effected under Section 10.06(a) or Section 10.06(b) above; (ii) dividends or distributions paid exclusively in cash; and (iii) spin-offs as defined below in this Section 10.06(c)), then the Conversion Rate will be increased based on the following formula:



CR = CR₀ ×	SP₀
	SP₀ - FMV

where,

CR₀ = the Conversion Rate in effect immediately prior to the Close of Business on the record date for such distribution;

CR = the Conversion Rate in effect immediately after the Close of Business on the record date for such distribution;

SP₀ = the average of the Closing Sale Prices of the Common Stock over the 10 consecutive trading-day period ending on, and including, the Trading Day immediately preceding the ex-dividend date for such distribution; and

FMV = the fair market value (as determined in good faith by the Company’s board of directors or a duly authorized committee thereof) of the shares of capital stock, evidences of indebtedness, assets or property or rights, options or warrants distributed with respect to each outstanding share of the Common Stock as of the Open of Business on the ex-dividend date for such distribution.

Any increase made under the above portion of this Section 10.06(c) will become effective immediately after the Close of Business on the record date for such distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of Securities shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Company’s Common Stock, without having to convert its Securities, the amount and kind of such distribution that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for the distribution.

With respect to an adjustment pursuant to this Section 10.06(c) where there has been an ex-dividend date for a dividend or other distribution on the Company’s Common Stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “spin-off”), the Conversion Rate will be increased based on the following formula:



CR = CR₀ ×	FMV + MP₀
	MP₀

where,

CR₀ = the Conversion Rate in effect immediately prior to the end of the valuation period (as defined below);

CR = the Conversion Rate in effect immediately after the end of the valuation period;

FMV = the average of the Closing Sale Prices of the capital stock or similar equity interest distributed to holders of the Company’s Common Stock applicable to one share of the Company’s Common Stock (determined by reference to the definition of “Closing Sale Price” as if references therein to our Common Stock were to such capital stock or similar equity interest) over the first 10 consecutive Trading Day period commencing on, and including, the ex-dividend date for the spin-off (such period, the “valuation period”); and

MP₀ = the average of the Closing Sale Prices of the Company’s Common Stock over the valuation period.

The adjustment to the Conversion Rate under the immediately preceding paragraph of this Section 10.06(c) will be determined on the last day of the valuation period but will be given effect immediately after the Open of Business on the ex-dividend date for the spin-off. In respect of any conversion during the valuation period for any spin-off, references within this Section 10.06(c) related to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the ex-dividend date for such spin-off to, but excluding, the relevant Conversion Date.

(d)If an ex-dividend date occurs for a cash dividend or distribution to all, or substantially all, holders of the outstanding Common Stock (other than any dividend or distribution in connection with the Company’s liquidation, dissolution or winding up), the Conversion Rate will be increased based on the following formula:



CR = CR₀ ×	SP₀
	SP₀ - C

where,

CR₀ = the Conversion Rate in effect immediately prior to the Close of Business on the record date for such distribution;

CR = the Conversion Rate in effect immediately after the Close of Business on the record date for such distribution;

SP₀ = the average of the Closing Sale Prices of the Company’s Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the ex-dividend date for such distribution; and

C = the amount in cash per share the Company pays or distributes to all or substantially all holders of the Company’s Common Stock.

Any increase made under this Section 10.06(d) shall become effective immediately after the Close of Business on the record date for such dividend or distribution. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate. However, if any dividend or distribution described in this Section 10.06(d) is declared but not so paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of Securities shall receive, for each $1,000 principal amount of Securities, at the same time and upon the same terms as holders of shares of the Company’s Common Stock, without having to convert its Securities, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the record date for such cash dividend or distribution.

(e)If the Company or any of its subsidiaries makes a payment in respect of a tender or exchange offer for the Company’s Common Stock and, if the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “expiration date”), the Conversion Rate will be increased based on the following formula:



CR = CR₀ ×	AC + (OS x SP)
	OS₀ x SP

where,

CR₀ = the Conversion Rate in effect immediately prior to the Open of Business on the Trading Day next succeeding the expiration date;

CR = the Conversion Rate in effect immediately after the Open of Business on the Trading Day next succeeding the expiration date;

AC = the aggregate value of all cash and any other consideration (as determined in good faith by the Company’s board of directors or a duly authorized committee thereof) paid or payable for shares purchased in such tender or exchange offer;

OS₀ = the number of shares of Common Stock outstanding immediately prior to the time (the “expiration time”) such tender or exchange offer expires (prior to giving effect to such tender or exchange offer);

OS = the number of shares of Common Stock outstanding immediately after the expiration time (after giving effect to such tender or exchange offer); and

SP = the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading-Day period commencing on, and including, the Trading Day next succeeding the expiration date.

The adjustment to the Conversion Rate under the preceding paragraph of this Section 10.06(e) will be determined at the Close of Business on the tenth Trading Day immediately following, but excluding, the expiration date but will be given effect at the Open of Business on the Trading Day next succeeding the expiration date. In respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the expiration date, references in this Section 10.06(e) to 10 Trading Days shall be deemed to be replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the expiration date to, but excluding, the relevant Conversion Date. No adjustment pursuant to the above formula will result in a decrease of the Conversion Rate.

(f)Notwithstanding any of the foregoing, the Conversion Rate will not be adjusted: (i) upon the issuance of Common Stock at a price below the conversion price or otherwise, unless otherwise described in the Conversion Rate adjustment provisions above; (ii) on account of share repurchases that are not tender offers referred to in Section 10.06(e) above, including structured or derivative transactions, or pursuant to a share repurchase program approved by the Company’s board of directors or otherwise; (iii) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan; (iv) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its subsidiaries; (v) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in the immediately preceding clause (iv) and outstanding as of the Issue Date; (vi) solely for a change in the par value of the Common Stock; or (vii) for accrued and unpaid interest, if any. If an adjustment to the Conversion Rate otherwise required by the Section 10.06(a)-(e) above would result in a change of less than 1.0% to the Conversion Rate, then, notwithstanding the foregoing, the Company may, at its election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest to occur of the following: (x) when all such deferred adjustments would result in an aggregate change of at least 1.0% to the Conversion Rate; or (y) the Conversion Date of any Security.

(g)In addition to the foregoing adjustments in Section 10.06(a)-(e) above, the Company may, from time to time and to the extent permitted by law and the applicable rules of the New York Stock Exchange (or other applicable Eligible Market), 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, as specified by the Board of Directors 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; provided, however, that, during the 12-month period immediately following the Issue Date (or in the case of Additional Securities, during the 12-month period immediately following the date of issuance of such Additional Securities), the Company is prohibited from increasing the Conversion Rate to an amount that is equal to or greater than 507.6142 shares of Common Stock per $1,000 principal amount of the Securities. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give written notice to the Trustee specifying the increase in Conversion Rate and cause notice of such increase to be mailed to each Holder of Securities at such Holder’s address as the same appears on the registry books of the Registrar, at least 15 days prior to the date on which such increase commences.

(h)As used in this Section 10.06, “ex-dividend date” means the first date on which the shares of the Company’s Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the applicable issuance, dividend or distribution, from the Company or, if applicable, from the seller of the Company’s Common Stock on such exchange or market (in the form of due bills or otherwise) as determined by such exchange or market.

(i)To the extent that the Company has a rights plan in effect at the time of any conversion of Securities (i.e., a poison pill), Holders will receive, in addition to the Common Stock received in connection with such conversion, the rights under the rights plan, unless prior to that conversion, the rights have separated from the Common Stock, in which case the Conversion Rate will be adjusted at the time of separation as if the Company had distributed to all holders of its Common Stock, shares of the Company’s capital stock, evidences of indebtedness or other assets or property as described in Section 10.06(c) above, subject to readjustment on any expiration, termination or redemption of such rights.

(j)Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000th of a share. Whenever any provision of this Indenture requires the Company to calculate Closing Sale Prices or Daily VWAPs over a span of multiple days, the Company’s board of directors or a duly authorized committee thereof will make appropriate adjustments to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate when the record date of the event occurs at any time during the period during which such Closing Sale Prices or Daily VWAPs are to be calculated.

(k)No adjustment to the Conversion Rate is required for a transaction if Holders will be entitled to participate in that transaction, without conversion of the Securities, on the same terms and at the same time as a holder of a number of shares of Common Stock equal to the principal amount of a Holder’s Securities divided by $1,000 and multiplied by the Conversion Rate would be entitled to participate.

Section 10.07No Adjustment. The Conversion Rate shall not be adjusted for any transaction or event other than as specified in this Article 10.

Section 10.08Adjustments for Tax Purposes. Except as prohibited by law, the Company may (but is not obligated to) increase the Conversion Rate, in addition to those adjustments required by or allowed under Section 10.06 hereof, as it determines to be advisable in order that any stock dividend, subdivision of shares, distribution of rights to purchase stock or securities or distribution of securities convertible into or exchangeable for stock made by the Company or to its shareholders will not be taxable to the recipients thereof or in order to avoid or diminish any such taxation.

Section 10.09Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the 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. In addition, the Company will issue a press release containing the relevant information relating to such Conversion Rate adjustment (and make the press release available on its website).

Section 10.10Notice of Certain Transactions. If:

(a)the Company or any of its subsidiaries takes any action that would require or effects an adjustment in the Conversion Rate,

(b)the Company takes any action that would require a supplemental indenture pursuant to Section 10.11, or

(c)there is a voluntary or involuntary dissolution, liquidation or winding up of the Company,

the Company will, as promptly as possible but in any event at least 20 days prior to the applicable date described below, mail to the Holders and the Trustee a written notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its subsidiaries, or (ii) the date on which such dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such dissolution, liquidation or winding-up.

Section 10.11Effect of Reclassification, Consolidation, Merger, Binding Share Exchange or Sale of Conversion Privilege.

(a)If the Company:

(i)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 10.06(a) applies);

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

(iii)sells, assigns, 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 entitled to receive stock, other securities, other property or cash for the Common Stock (any such event, a “Merger Event”), each $1,000 principal amount of Securities 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 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 permitted under Section 9.01 providing for such change in the right to convert the Securities. If the Securities become convertible into Reference Property, the Company will notify the Trustee in writing and issue a press release containing the relevant information (and make the press release available on the Company’s website).

(b)If a 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 any part upon any form of stockholder election), then the Reference Property into which the Securities 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.

(c)The Company shall notify in writing 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.

(d)The supplemental indenture referred to in the first sentence of this Section 10.11 shall, in the good faith judgment of the Company as evidenced by an Officers’ Certificate, (1) provide for

adjustments to the Conversion Rate and Threshold Price that shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate and Threshold Price provided for in this Article 10 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 (2) provide that after the Merger Event, the Daily VWAP (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 Securities upon a Change of Control in accordance with Section 4.09, as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 10.11 shall similarly apply to successive Merger Events.

(e)The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 10.11.

(f)None of the foregoing provisions shall affect the right of a Holder to convert its Securities into shares of Common Stock (and cash in lieu of any fractional share) as set forth in Section 10.01(a) and Section 10.02 prior to the effective date of a Merger Event, or the right of the Company to effect a Mandatory Conversion prior to the effective date of a Merger Event in accordance with Section 10.01(b).

(g)If the Company shall execute a supplemental indenture pursuant to this Section 10.11, the Company shall promptly file with the Trustee and the Conversion Agent an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Securities upon the conversion of their Securities after any such Merger Event and any adjustment to be made with respect thereto.

Section 10.12Calculations. The Company will be responsible for making all calculations called for under the Securities and this Indenture. These calculations include, but are not limited to, determinations of the sale prices of the Common Stock, the Daily VWAPs, accrued interest payable on the Securities, and the Conversion Rate. The Company will make all these calculations in good faith and, absent manifest error, the Company’s calculations shall be final and binding on Holders. The Company will provide a schedule of its calculations to each of the Trustee and the Conversion Agent (if other than the Trustee), and each of the Trustee and the Conversion Agent (if other than the Trustee) is entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification. The Trustee and the Conversion Agent shall not have any liability or responsibility in connection with any calculation or information relating to any calculation. Neither the Trustee nor the Conversion Agent shall have any responsibility or obligation to determine when and if any Notes may be converted at any time. The Trustee will forward the Company’s calculations to any Holder upon the request of that Holder at the Company’s sole cost and expense.

Section 10.13Trustee’s Disclaimer. The Trustee and the Conversion Agent have no duty or responsibility to determine when an adjustment under this Article 10 must or may be made, how it must or may be made or what such adjustment must or may be, but 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 10.09 hereof. The Trustee and the Conversion Agent make no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the failure by the Company to comply with any provision of this Article 10.

The Trustee and the Conversion Agent shall not be under any responsibility to determine the correctness of any provision contained in any supplemental indenture executed pursuant to Section 10.11, 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 10.11 hereof.

ARTICLE 11

Subsidiary Guarantees

Section 11.01Subsidiary Guarantees. Each Subsidiary Guarantor, jointly and severally, as primary obligor and not merely as surety, hereby irrevocably, fully and unconditionally Guarantees on a senior unsecured basis to each Holder and to the Trustee and their respective successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due, whether at Stated Maturity, by acceleration or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Securities (all the foregoing obligations hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor, and that such Subsidiary Guarantor shall remain bound under this Article 11 notwithstanding any extension or renewal of any such Guaranteed Obligation.

Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (e) the failure of any Holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (f) except as provided in Section 11.06, any change in the ownership of such Subsidiary Guarantor.

Each Subsidiary Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or

by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

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

Each Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the Guaranteed Obligations Guaranteed hereby may be accelerated as provided in Article 6 for the purposes of such Subsidiary Guarantor’s Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations Guaranteed hereby, and (y) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section.

Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section.

Section 11.02Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum, aggregate amount of the obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed by such Subsidiary Guarantor without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Section 11.03Successors and Assigns. This Article 11 shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the

Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

Section 11.04No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in equity, by statute or otherwise.

Section 11.05Modification. No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.

Section 11.06Release of Subsidiary Guarantor. The Guarantee of a Subsidiary Guarantor shall be automatically and unconditionally released and discharged:

(a)upon payment in full in cash and discharge of all amounts due in respect of the Securities outstanding under this Indenture after the Securities have become due and payable, whether at maturity, upon conversion or otherwise;

(b)in connection with any sale, transfer or other disposition of (x) the Capital Stock of such Subsidiary Guarantor, after which such Subsidiary Guarantor is no longer a Restricted Subsidiary or (y) all or substantially all of the assets of such Subsidiary Guarantor, in each case, to a Person that is not (either before or after such sale, transfer or disposition) the Company or a Subsidiary of the Company in a transaction or other circumstance that does not violate Section 4.07(a) and is otherwise permitted by this Indenture, at the time of such sale, transfer or other disposition; or

(c)upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture.

Upon receipt of an Officers’ Certificate and an Opinion of Counsel, the Trustee shall execute, deliver or acknowledge any necessary or proper instruments of termination or release prepared by the Company or any Subsidiary Guarantor permitted to be released pursuant to this Section 11.06.

In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee actually knows are so owned shall be so disregarded.

EACH OF THE COMPANY, THE SUBSIDIARY GUARANTORS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE SECURITIES, THE SUBSIDIARY GUARANTEES, THE GUARANTEE AGREEMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 13.17Set-Off of Withholding Taxes. If the Company is required by applicable law to pay, and pays, withholding tax on behalf of a non-U.S. Holder as a result of an adjustment to the Conversion Rate, the Company may, at its option, set off or cause to be set off such withholding tax against any payments of cash or shares of Common Stock on the Securities (or, if such withholding tax has not previously been fully set off against such cash or shares of Common Stock). For purposes of such a set-off, each share of Common Stock shall be deemed to have a value equal to the Daily VWAP of the Common Stock on the Conversion Date applicable to such Security.

IN WITNESS WHEREOF, the parties have caused this Indenture to be duly executed as of the date first written above.

FORM OF REVERSE SIDE OF SECURITY

1. Interest

Denbury Resources Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Company shall pay interest semiannually on March 31 and September 30 of each year, commencing March 31, 2018. Interest on the Securities shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from December 6, 2017. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. The Company shall pay interest on overdue principal at the rate borne by the Securities plus 1% per annum, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

2. Method of Payment

The Company shall pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the Close of Business on the March 15 and September 15 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company shall make all payments in respect of a certificated Security (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security shall be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent, Registrar and Conversion Agent

Initially, Wilmington Trust, National Association (the “Trustee”), shall act as Paying Agent, Registrar and Conversion Agent. The Company may appoint and change any Paying Agent, Registrar, co-registrar or Conversion Agent without notice. The Company or any Wholly-Owned Subsidiary may act as Paying Agent, Registrar, co-registrar or Conversion Agent.

4. Indenture

The Company issued the Securities under an Indenture dated as of December 6, 2017 (“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those expressly made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the Issue Date (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms.

Exhibit B - 1

The Securities are general senior unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Sections 4.03 and 4.10 of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Securities issued on the Issue Date and any Additional Securities shall be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur or guarantee additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; engage in transactions with affiliates; transfer or sell assets; incur liens; restrict dividends or other payments of subsidiaries; and consolidate, merge or transfer all or substantially all of their assets and the assets of their subsidiaries. These covenants are subject to important exceptions and qualifications.

5. Put Provisions

Upon a Change of Control, any Holder shall have the right to cause the Company to repurchase all or any part of the Securities of such Holder at a purchase price equal to 101% of the principal amount of the Securities to be repurchased on the date of purchase plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

6. Designation of Security

The Securities and the Subsidiary Guarantees shall constitute “Senior Indebtedness,” and the Company and the Subsidiary Guarantors hereby designate the Securities and the Subsidiary Guarantees as “Designated Senior Indebtedness” of the Company and the Subsidiary Guarantors, for purposes of the Existing Subordinated Notes Indentures. The Securities and the Subsidiary Guarantees shall be superior in right of payment to the Existing Subordinated Notes and the Guarantees thereof or any other Subordinated Obligations.

7. Guarantees

The payment by the Company of the principal of, and premium (if any) and interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior secured second lien basis by each of the Subsidiary Guarantors on the terms set forth in the Indenture.

8. Denominations; Transfer; Exchange

The Securities are in registered form without coupons in minimum denominations of $2,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities 15 days before an interest payment date.

9. Persons Deemed Owners

The registered Holder of this Security may be treated as the owner of it for all purposes.

10. Unclaimed Money

If money for the payment of principal, premium (if any) or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an

Exhibit B - 2

abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

11. Discharge

The Securities are subject to discharge upon the terms and conditions specified in the Indenture.

12. Amendment, Waiver

The Note Documents may be amended or supplemented, and any existing or past Default may be waived, as provided in the Indenture.

13. Defaults and Remedies

The Events of Default with respect to the Notes are set forth in Section 6.01 of the Indenture. Upon the occurrence of an Event of Default, the rights and obligations of the Company, the Subsidiary Guarantors, the Trustee, the Collateral Trustee and the Holders are as provided in the Indenture.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.

14. Conversion. The Securities shall be convertible into shares of Common Stock in accordance with Article 10 of the Indenture. To convert a Security at its option, a Holder must satisfy the requirements of Section 10.01(a) of the Indenture. A Holder may convert a portion of a Security in an Optional Conversion if the portion is $1,000 principal amount or an integral multiple of $1,000 principal amount. Upon conversion of a Security pursuant to an Optional Conversion, the Holder thereof shall be entitled to receive the shares of Common Stock payable upon conversion in accordance with Article 10 of the Indenture, at the Conversion Rate, as adjusted from time to time in accordance with Article 10 of the Indenture. The Securities shall be convertible into Common Stock in accordance with Section 10.01(b) of the Indenture and the conditions to Mandatory Conversion specified therein. Upon conversion of a Security pursuant to a Mandatory Conversion, the Holder thereof shall be entitled to receive the shares of Common Stock payable upon conversion in accordance with Article 10 of the Indenture, at the Conversion Rate, as adjusted from time to time in accordance with Article 10 of the Indenture.

15. Trustee Dealings with the Company

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

16. No Recourse Against Others

A director, officer, employee, stockholder, incorporator, or member, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities, any Subsidiary Guarantee, or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each

Exhibit B - 3

Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

17. Authentication

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

18. Abbreviations
