shall be borne by any such Global Security in addition to or in lieu of that set forth in Section 2.15 or Exhibit A and any circumstances in addition to or in lieu of those set forth in the Indenture in which any such Global Security may be exchanged in whole or in part for 7⅞% Notes registered, and any transfer of such Global Security in whole or in part may be registered, in the name or names of Persons other than the Depositary for such Global Security or a nominee thereof; and

(e) if not offered pursuant to an exemption from registration, that such Additional 7⅞% Notes shall be registered under the Securities Act and shall not be required to bear the Private Placement Legend.

(B) estimated oil and gas reserves attributable to upward revisions of estimates of proved oil and gas reserves since such year end due to exploration, development or exploitation activities, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year end reserve report),

(D) estimated oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since such year end due to changes in geological conditions or other factors that would, in accordance with standard industry practice, cause such revisions, in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such year end reserve report),

provided 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 petroleum engineers, unless there is a Material Change as a result of such acquisitions, dispositions or revisions, in which event the discounted future net revenues utilized for purposes of this clause (a)(1) shall be confirmed in writing by a nationally recognized firm of independent petroleum engineers,

(f) loans, in an aggregate principal amount at any one time outstanding of not more than $2.0 million, made to officers, directors or employees of the Company or any Restricted Subsidiary approved by the Board of Directors (or by a duly authorized officer) and in compliance with the Sarbanes-Oxley Act of 2002, the net cash proceeds of which are used solely:

(1) to purchase common stock of the Company in connection with a restricted stock or employee stock purchase plan, or to exercise stock options received pursuant to an employee or director stock option plan or other incentive plan, in a principal amount not to exceed the purchase price of such common stock or the exercise price of such stock options, or

(2) to refinance loans, together with accrued interest thereon, made pursuant to item (1) of this clause (f).

The actions described in clauses (a) and (b) of this paragraph shall be included in the calculation of the amount of Restricted Payments. The actions described in clauses (c), (d), (e) and (f) of this paragraph shall be

SECTION 4.13. [This Section is intentionally omitted.]

SECTION 4.14. Limitation on Asset Sales. The Company will not, and will not permit any Restricted Subsidiary to, consummate any Asset Sale unless:

(a) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the Property subject to such Asset Sale; and

(b) all of the consideration paid to the Company or such Restricted Subsidiary in connection with such Asset Sale is in the form of cash, Permitted Short-Term Investments, Liquid Securities, Exchange Properties or the assumption by the purchaser of liabilities of the Company (other than liabilities of the Company that are by their terms subordinated to the 7⅞% Notes) or liabilities of any Subsidiary Guarantor that made such Asset Sale (other than liabilities of a Subsidiary Guarantor that are by their terms subordinated to such Subsidiary Guarantor’s Subsidiary Guarantee), in each case as a result of which the Company and its remaining Restricted Subsidiaries are no longer liable for such liabilities, such consideration being defined as “Permitted Consideration”; provided, however, that the Company and its Restricted Subsidiaries shall be permitted to receive Property other than Permitted Consideration, so long as the aggregate Fair Market Value of all such Property other than Permitted Consideration received from Asset Sales and held by the Company or any Restricted Subsidiary at any one time shall not exceed 10.0% of Adjusted Consolidated Net Tangible Assets.

The Net Available Cash from Asset Sales by the Company or a Restricted Subsidiary may be applied by the Company or such Restricted Subsidiary, to the extent the Company or such Restricted Subsidiary elects (or is required by the terms of any Senior Indebtedness of the Company or a Subsidiary Guarantor), to:

(a) prepay, repay or purchase Senior Indebtedness of the Company or a Subsidiary Guarantor (in each case excluding Indebtedness owed to the Company or an Affiliate of the Company);

(b) to reinvest in Additional Assets (including by means of an Investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by the Company or another Restricted Subsidiary);

(c) purchase 7⅞% Notes or purchase both 7⅞% Notes and one or more series or issues of other Senior Indebtedness on a pro rata basis (excluding 7⅞% Notes and Pari Passu Indebtedness owed to the Company or any of its Affiliates) in accordance with the next paragraph; or

(d) enter into a bona fide binding contract with a Person other than an Affiliate of the Company to apply the Net Available Cash pursuant to clause (b) above, provided that such binding contract shall be treated as a permitted application of the Net Available Cash from the date of such contract until the earlier of

(1) the date on which such reinvestment is consummated, and

(2) the 90th day following the expiration of the 365-day period referred to in the next following sentence.

Any Net Available Cash from an Asset Sale not applied in accordance with the preceding paragraph within 365 days from the date of such Asset Sale shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, the Company will be required to make an offer (a “Prepayment Offer”) to purchase 7⅞% Notes having an aggregate principal amount equal to the aggregate amount of Excess Proceeds at a purchase price equal to 100% of the principal amount of such 7⅞% Notes plus accrued and unpaid interest, if any, to the Purchase Date (as defined) in accordance with the procedures (including proration in the event of oversubscription) set forth in this Indenture, but, if the terms of any other Senior Indebtedness require that a Senior Indebtedness Offer be made contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be prorated between the Prepayment Offer and such Senior Indebtedness Offer in accordance with the aggregate Outstanding principal amounts of the 7⅞% Notes and such other Senior Indebtedness, and the aggregate principal amount of 7⅞% Notes for which the Prepayment Offer is made shall be reduced accordingly. If the aggregate principal amount of 7⅞% Notes tendered by Holders thereof exceeds the amount of available Excess Proceeds, then such Excess Proceeds will be allocated pro rata according to the principal amount of the 7⅞% Notes tendered and the Trustee will select the 7⅞% Notes to be purchased in accordance with this Indenture. To the extent that any portion of the amount of Excess Proceeds remains after compliance with the second sentence of this paragraph and provided that all Holders of 7⅞% Notes have been given the opportunity to tender their 7⅞% Notes for purchase as described in the following paragraph in accordance with this Indenture, the Company and its Restricted Subsidiaries may use such remaining amount for purposes permitted by this Indenture and the amount of Excess Proceeds will be reset to zero.

Within 30 days after the 365th day following the date of an Asset Sale, the Company shall, if it is obligated to make an offer to purchase the 7⅞% Notes pursuant to the preceding paragraph, send a written Prepayment Offer notice, by

first-class mail, to the Holders of the 7⅞% Notes (the “Prepayment Offer Notice”), accompanied by such information regarding the Company and its Subsidiaries as the Company believes will enable such Holders of the 7⅞% Notes to make an informed decision with respect to the Prepayment Offer. The Prepayment Offer Notice will state, among other things:

(a) that the Company is offering to purchase 7⅞% Notes pursuant to the provisions of this Indenture;

(b) that any 7⅞% Note (or any portion thereof) accepted for payment (and duly paid on the Purchase Date) pursuant to the Prepayment Offer shall cease to accrue interest on the Purchase Date;

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

(e) the aggregate principal amount of 7⅞% Notes to be purchased;

(f) a description of the procedure that Holders of 7⅞% Notes must follow in order to tender their 7⅞% Notes for payment; and

(g) all other instructions and materials necessary to enable Holders to tender 7⅞% Notes pursuant to the Prepayment Offer.

The Company will comply, to the extent applicable, with the requirements of Section 14(e) under the Exchange Act and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of 7⅞% Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Prepayment Offer, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations described above by virtue thereof.

SECTION 4.15. Covenant Termination. If at any time (a) the rating assigned to the 7⅞% Notes by each of S&P and Moody’s is an Investment Grade Rating and (b) no Default has occurred and is continuing, the Company and its Restricted Subsidiaries will no longer be subject to the covenants set forth in Sections 4.11, 4.12, 4.14, 4.16, 4.17 and 4.18, and clause (d) of Section 10.01. After these certain covenants have terminated pursuant to this Section 4.15, the Company may not designate any Subsidiary of the Company as an Unrestricted Subsidiary.

SECTION 4.16. Limitation on Transactions with Affiliates. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, conduct any business or enter into any transaction or series of transactions (including the sale, transfer, disposition, purchase, exchange or lease of Property, the making of any Investment, the giving of any Guarantee or the rendering of any service) with or for the benefit of any Affiliate of the Company (other than the Company or a Wholly Owned Subsidiary), unless:

(a) such transaction is set forth in writing;

(b) such transaction or series of transactions is on terms no less favorable to the Company or such Restricted Subsidiary than those that could be obtained in a comparable arm’s-length transaction with a Person that is not an Affiliate of the Company or such Restricted Subsidiary; and

(c) with respect to a transaction or series of transactions involving aggregate payments by or to the Company or such Restricted Subsidiary having a Fair Market Value equal to or in excess of:

(1) $15.0 million but less than $25.0 million, the Board of Directors of the Company (including a majority of the disinterested members of such Board of Directors) approves such transaction or series of transactions and certifies that such transaction or series of transactions complies with clause (b) of this paragraph, as evidenced by a certified resolution delivered to the Trustee, or

(2) $25.0 million,

(A) the Company receives from an independent, nationally recognized investment banking firm or appraisal firm, in either case specializing or having a specialty in the type and subject matter of the transaction (or series of transactions) at issue, a written opinion that such transaction (or series of transactions) is fair, from a financial point of view, to the Company or such Restricted Subsidiary, and

(B) such Board of Directors (including a majority of the disinterested members of the Board of Directors of the Company) approves such transaction or series of transactions and certifies that such transaction or series of transactions complies with clause (b) of this paragraph, as evidenced by a certified resolution delivered to the Trustee.

The preceding limitations of this Section 4.16 do not apply to:

(a) the payment of reasonable and customary regular fees to directors of the Company or any of its Restricted Subsidiaries who are not employees of the Company or any of its Restricted Subsidiaries;

(b) indemnities of officers and directors of the Company or any Subsidiary consistent with such Person’s charter, bylaws and applicable statutory provisions;

(c) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and employee stock purchase and ownership plans approved by the Board of Directors of the Company;

(d) loans made in compliance with the Sarbanes-Oxley Act of 2002:

(1) to officers, directors or employees of the Company or any Restricted Subsidiary approved by the Board of Directors of the Company, the net proceeds of which are used solely to purchase common stock of the Company in connection with a restricted stock or employee stock purchase plan, or to exercise stock options received pursuant to an employee or director stock option plan or other incentive plan, in a principal amount not to exceed the purchase price of such common stock or the exercise price of such stock options, or

(2) to refinance loans, together with accrued interest thereon, made pursuant to this clause (d);

(e) advances and loans made in compliance with the Sarbanes-Oxley Act of 2002 to officers, directors and employees of the Company or any Subsidiary in the ordinary course of business (including, without limitation, non-cash loans for the purchase of joint interests in exploratory and developmental oil and gas prospects or other similar ventures offered by the Company), provided such loans and advances (excluding loans or advances made pursuant to the preceding clause (d)) do not exceed $2.0 million at any one time outstanding;

(f) any Restricted Payment permitted to be paid pursuant to Section 4.12;

(g) any transaction or series of transactions between the Company and one or more Restricted Subsidiaries or between two or more Restricted Subsidiaries in the ordinary course of business, provided that no more than 10% of the total voting power of the Voting Stock of any such

Restricted Subsidiary is owned by an Affiliate of the Company (other than a Restricted Subsidiary); and

(h) any transaction or series of transactions pursuant to any agreement or obligation of the Company or any of its Restricted Subsidiaries in effect on the Issue Date.

SECTION 4.17. Limitation on Restrictions on Distributions from Restricted Subsidiaries. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction on the legal right of any Restricted Subsidiary to:

(a) pay dividends, in cash or otherwise, or make any other distributions on or in respect of its Capital Stock, or pay any Indebtedness or other obligation owed, to the Company or any other Restricted Subsidiary;

(b) make loans or advances to the Company or any other Restricted Subsidiary; or

Such limitation will not apply:

(1) with respect to clauses (a), (b) and (c), to encumbrances and restrictions:

(A) in agreements and instruments (including any Bank Credit Facilities) as in effect on the Issue Date,

(B) relating to Indebtedness of a Restricted Subsidiary and existing at the time it became a Restricted Subsidiary if such encumbrance or restriction was not created in anticipation of or in connection with the transactions pursuant to which such Restricted Subsidiary became a Restricted Subsidiary, or

(C) that result from the renewal, refinancing, extension or amendment of an agreement that is the subject of clause (c)(1)(A) or (B) above or clause (c)(2)(A) or (B) below, provided that such encumbrance or restriction is not materially less favorable to the Holders of 7⅞% Notes than those under or pursuant to the agreement so renewed, refinanced, extended or amended, as determined in good faith by the Board of Directors of the Company and,

(2) with respect to clause (c) only, to:

(A) restrictions pursuant to Liens permitted to be Incurred and secured without also securing the 7⅞% Notes under Section 4.10 and that limit the right of the debtor to dispose of the Property subject to such Lien,

(B) any encumbrance or restriction applicable to Property at the time it is acquired by the Company or a Restricted Subsidiary, so long as such encumbrance or restriction relates solely to the Property so acquired and was not created in anticipation of or in connection with such acquisition,

(C) customary provisions restricting subletting or assignment of leases and customary provisions in other agreements that restrict assignment of such agreements or rights thereunder, and

(D) customary restrictions contained in asset sale agreements limiting the transfer of such assets pending the closing of such sale.

SECTION 4.18. Future Subsidiary Guarantors. The Company shall cause each Restricted Subsidiary (except an Exempt Foreign Subsidiary) that:

(a) Incurs Indebtedness or issues Preferred Stock following the Issue Date; or

(b) has Indebtedness or Preferred Stock outstanding on the date on which such Restricted Subsidiary becomes a Restricted Subsidiary,

to execute and deliver to the Trustee a supplemental indenture providing for a Subsidiary Guarantee pursuant to Section 14.06 at the time such Restricted Subsidiary Incurs such Indebtedness or becomes a Restricted Subsidiary; provided, however, that such Restricted Subsidiary shall not be required to deliver a supplemental indenture providing for a Subsidiary Guarantee if the aggregate amount of such Indebtedness or Preferred Stock, together with all other Indebtedness and Preferred Stock then outstanding among Restricted Subsidiaries (including Exempt Foreign Subsidiaries) that are not Subsidiary Guarantors, is less than $10.0 million.

Any Subsidiary Guarantor that no longer has any outstanding Indebtedness or Preferred Stock or that again qualifies as an Exempt Foreign Subsidiary shall be released from and relieved of its obligations under its Subsidiary Guarantee upon execution and delivery of a supplemental indenture in form satisfactory to the Trustee.

SECTION 4.19. Restricted and Unrestricted Subsidiaries. Unless defined or designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of the Company or any of its Restricted Subsidiaries shall be classified as a Restricted Subsidiary subject to the provisions of the next paragraph. The Company may designate a Subsidiary (including a newly formed or newly acquired Subsidiary) of the Company or any of its Restricted Subsidiaries as an Unrestricted Subsidiary if:

(a) such Subsidiary does not at such time own any Capital Stock or Indebtedness of, or own or hold any Lien on any Property of, the Company or any other Restricted Subsidiary;

(b) such Subsidiary does not at such time have any Indebtedness or other obligations that, if in default, would result (with the passage of time or notice or otherwise) in a default on any Indebtedness of the Company or any Restricted Subsidiary; and

(c) (1) such designation is effective immediately upon such Subsidiary becoming a Subsidiary of the Company or of a Restricted Subsidiary,

(2) the Subsidiary to be so designated has total assets of $1,000 or less, or

(3) if such Subsidiary has assets greater than $1,000, then such redesignation as an Unrestricted Subsidiary is deemed to constitute a Restricted Payment in an amount equal to the Fair Market Value of the Company’s direct and indirect ownership interest in such Subsidiary, and such Restricted Payment would be permitted to be made at the time of such designation under Section 4.12.

Except as provided in the immediately preceding sentence, no Restricted Subsidiary may be designated as an Unrestricted Subsidiary. The designation of an Unrestricted Subsidiary or removal of such designation shall be made by the Board of Directors of the Company or a committee thereof pursuant to a certified resolution delivered to the Trustee and shall be effective as of the date specified in the applicable certified resolution, which shall not be prior to the date such certified resolution is delivered to the Trustee. Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in accordance with the terms of this Section 4.19 shall be released from and relieved of its obligations under its Subsidiary Guarantee upon execution and delivery of a supplemental indenture in form satisfactory to the Trustee.

SECTION 4.20. Change of Control. Upon the occurrence of a Change of Control, each Holder of 7⅞% Notes shall have the right to require the Company to repurchase all or any part (equal to $2,000 in principal amount or an integral

multiple of $1,000 in excess thereof) of such Holder’s 7⅞% Notes pursuant to the offer described below (the “Change of Control Offer”) at a purchase price in cash (a “Change of Control Payment”) equal to 101% of the principal amount of the 7⅞% Notes repurchased, 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 due on the relevant interest payment date.

Within 30 days following any Change of Control, the Company shall:

(a) cause a notice of the Change of Control Offer to be sent at least once to the Dow Jones News Service or similar business news service in the United States; and

(b) send, by first-class mail, with a copy to the Trustee, to each Holder of 7⅞% Notes, at such Holder’s address appearing in the Debt Security Register, a notice stating, among other things:

(1) that a Change of Control has occurred and a Change of Control Offer is being made pursuant to this Indenture and that all 7⅞% Notes (or portions thereof) properly tendered will be accepted for payment,

(2) the Change of Control Payment and the purchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 30 days nor later than 60 days from the date the Company mails such notice (the “Change of Control Payment Date”),

(3) that any 7⅞% Note (or portion thereof) accepted for payment (and duly paid on the Change of Control Payment Date) pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date,

(4) that any 7⅞% Note (or portions thereof) not properly tendered will continue to accrue interest,

(5) a description of the transaction or transactions constituting the Change of Control,

(6) the procedures that the Holders of the 7⅞% Notes must follow in order to tender their 7⅞% Notes (or portions thereof) for payment and the procedures that Holders of 7⅞% Notes must follow in order to withdraw an election to tender 7⅞% Notes (or portions thereof) for payment, and

(7) all other instructions and materials necessary to enable Holders to tender 7⅞% Notes pursuant to the Change of Control Offer.

The Company will comply, to the extent applicable, with the requirements of Section 14(e) under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of 7⅞% Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Change of Control Offer, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.20 by virtue of such compliance.

The Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.20 applicable to a Change of Control Offer made by the Company and purchases all 7⅞% Notes validly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption of all Outstanding 7⅞% Notes has been given pursuant to Section 3.02, unless and until there is a default in payment of the applicable redemption price.

The provisions of this Section 4.20 related to the obligation of the Company to make an offer to repurchase the Notes as a result of a Change of Control may be waived or amended, at any time prior to the occurrence of such Change of Control, with the consent (evidenced as provided in Section 8.01) of the Holders of a majority in principal amount of the Notes.

In the event that Holders of not less than 90% of the aggregate principal amount of the Outstanding 7⅞% Notes accept a Change of Control Offer and the Company (or a third party as described above) purchases all of the 7⅞% Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer referred to above, to redeem all of the 7⅞% Notes that remain Outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the 7⅞% Notes that remain Outstanding, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).”

SECTION 5. Amendments to Article V of the Original Indenture. Section 5.03 of the Original Indenture is amended in its entirety with respect to the 7⅞% Notes to read as follows:

applicable to a United States corporation subject to such Sections, such information, documents and reports to be so filed and provided at the times specified for the filing of such information, documents and reports under such Sections; provided, however, that the Company shall not be so obligated to file such information, documents and reports with the SEC if the SEC does not permit such filings. To the extent such reports are available to the public via the SEC’s EDGAR system, they will be deemed as being provided to the Trustee on the date they become available. Delivery of such information, documents and other reports to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

The Company agrees that, for so long as any 7⅞% Notes are Outstanding, if at any time it is not required to file with the SEC the reports described in the preceding paragraph of this Section 5.03, it will furnish to the holders of Notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.”

(b) in the case of a disposition of all or substantially all the Property of the Company and the Restricted Subsidiaries taken as a whole, such Property shall have been so disposed of, as an entirety or virtually as an entirety to one Person;

(c) immediately after giving effect to such transaction (and treating, for purposes of this clause (c) and clause (d) below, any Indebtedness that becomes or is anticipated to become an obligation of the Successor Company or any Restricted Subsidiary as a result of such transaction as having been Incurred by such Successor Company or such Restricted Subsidiary at the time of such transaction), no Default or Event of Default shall have occurred and be continuing;

(d) either:

(1) the Successor Company will, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio test set forth in clause (a) of Section 4.11; or

(2) immediately after giving effect to such transaction on a pro forma basis and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, the Consolidated Interest Coverage Ratio of the Successor Company will be equal to or greater than the Consolidated Interest Coverage Ratio of the Company immediately before such transaction; and

(e) the Company shall have delivered to the Trustee an Officers’ Certificate and an opinion of counsel, each stating that such consolidation, merger or disposition and such supplemental indenture (if any) comply with this Indenture;

provided, however, that clause (d) will not be applicable to (1) a Restricted Subsidiary consolidating with, merging with or into or selling, transferring, leasing or otherwise disposing of all or substantially all its Property to the Company or a Subsidiary Guarantor that is a Wholly Owned Subsidiary or (2) the Company merging with or into an Affiliate of the Company solely for the purpose and with the sole effect of reincorporating the Company in another jurisdiction.”

(b) Section 10.02 of the Original Indenture is amended by deleting the period at the end of the first sentence of the first paragraph thereof and by substituting the following in its place:

“; provided, however, that in the case of a lease of all or substantially all of the Company’s Property, the Company shall not be released from any of the obligations or covenants under this Indenture, including the obligation to pay the principal of and interest on the Debt Securities.”

SECTION 10. Applicability of and Amendments to Article XI of the Original Indenture

(a) Article XI of the Original Indenture shall be applicable to the 7⅞% Notes.

(b) Section 11.02(b) of the Original Indenture is superseded with respect to the 7⅞% Notes by the following provisions:

“(b) Subject to Sections 11.02(c) and 11.03, the Company at any time may terminate (i) all its obligations under the 7⅞% Notes and this Indenture with respect to the 7⅞% Notes (“legal defeasance option”) or (ii) its obligations under

Sections 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20 and 10.01(d), the operation of Sections 6.01(d) (to the extent relating to Section 10.01(d)), 6.01(e) (to the extent relating to Sections 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20), 6.01(f), 6.01(g) (to the extent relating to Significant Subsidiaries), 6.01(h) (to the extent relating to Significant Subsidiaries), 6.01(j) and 6.01(k) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

If the Company exercises its legal defeasance option, payment of the 7⅞% Notes may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option, payment of the 7⅞% Notes may not be accelerated because of an Event of Default specified in Sections 6.01(d) and 6.01(e) (with respect to the provisions of Articles IV and X referred to in the immediately preceding paragraph), Section 6.01(f), Sections 6.01(g) and 6.01(h) (in each case to the extent relating to Significant Subsidiaries), and Sections 6.01(j) and 6.01(k). If the Company exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor, if any, shall be released from all its obligations under its Subsidiary Guarantee.

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

Thereafter, the Company’s obligations in Sections 7.06, 11.05 and 11.06 shall survive.”

(d) Section 11.03(a) of the Original Indenture is amended in its entirety with respect to the 7⅞% Notes to read as follows:

SECTION 11. Inapplicability of Article XII of the Original Indenture

Article XII of the Original Indenture shall not be applicable to the 7⅞% Notes. The Notes shall be Senior Indebtedness of the Company, and the Subsidiary Guaranties shall be Senior Indebtedness of each Subsidiary Guarantor.

SECTION 12. Subsidiary Guaranties

(a) The Original Indenture is amended with respect to the 7⅞% Notes by deleting the proviso to Section 2.03(20) and adding Article XIV as follows:

“ARTICLE XIV

Subsidiary Guaranties

SECTION 14.01. Subsidiary Guaranties. Each Subsidiary Guarantor hereby unconditionally Guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the 7⅞% Notes when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the 7⅞% Notes and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the 7⅞% Notes (all the foregoing being hereinafter collectively called the “Obligations”). Each Subsidiary Guarantor further agrees that the 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 will remain bound under this Article XIV notwithstanding any extension or renewal of any Obligation.

Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any Default under the 7⅞% Notes or the 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 7⅞% Notes 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 7⅞% Notes or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder or the Trustee to exercise any right or remedy against any other Guarantor of the Obligations; or (f) any change in the ownership of such Subsidiary Guarantor.

Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee 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 Obligations.

Upon the sale or other disposition of all of the Capital Stock of a Subsidiary Guarantor (other than to the Company or an Affiliate thereof) in compliance with Section 4.14, such Subsidiary Guarantor shall be released from all obligations under its Subsidiary Guarantee. Except as expressly set forth in this Section 14.01 and Sections 4.18, 4.19 and 11.02, 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 7⅞% Notes or any other agreement, by any waiver or modification of any thereof, by any Default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of 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 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 Obligation when and as the same shall become due, whether at Stated Maturity, by acceleration, by redemption or otherwise, or to perform or

comply with any other Obligation, each Subsidiary Guarantor hereby promises to and will, 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 amount of such Obligations, (ii) accrued and unpaid interest on such Obligations (but only to the extent not prohibited by law) and (iii) all other monetary Obligations of the Company to the Holders and the Trustee. 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 Obligations Guaranteed hereby may be accelerated as provided in Article VI for the purposes of such Subsidiary Guarantor’s Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations Guaranteed hereby, and (y) in the event of any declaration of acceleration of such Obligations as provided in Article VI, such 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 14.01.

SECTION 14.02. Contribution. Each of the Company and any Subsidiary Guarantor (a “Contributing Party”) agrees that, in the event a payment shall be made by any other Subsidiary Guarantor under any Subsidiary Guarantee (the “Claiming Guarantor”), the Contributing Party shall indemnify the Claiming Guarantor in an amount equal to the amount of such payment multiplied by a fraction, the numerator of which shall be the net worth of the Contributing Party on the date hereof and the denominator of which shall be the aggregate net worth of the Company and all the Subsidiary Guarantors on the date hereof (or, in the case of any Subsidiary Guarantor becoming a party hereto pursuant to Section 9.01(n), the determination of indemnification amounts shall be based upon net worth on the date of the supplemental indenture executed and delivered by such Subsidiary Guarantor.)

SECTION 14.03. Successors and Assigns. This Article XIV 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 7⅞% Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 14.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article XIV 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 XIV at law, in equity, by statute or otherwise.

SECTION 14.05. Modification. No modification, amendment or waiver of any provision of this Article XIV, 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 14.06. Execution of Supplemental Indenture for Future Subsidiary Guarantors. Each Subsidiary which is required to become a Subsidiary Guarantor pursuant to Section 4.18 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit E hereto pursuant to which such Subsidiary shall become a Subsidiary Guarantor under this Article XIV and shall Guarantee the Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Subsidiary Guarantee of such Subsidiary Guarantor is a legal, valid and binding obligation of such Subsidiary Guarantor, enforceable against such Subsidiary Guarantor in accordance with its terms.”

(b) Opco shall guarantee the 7⅞% Notes in accordance with the provisions of Article XIV of the Original Indenture.

SECTION 13. Governing Law. This Second Supplemental Indenture shall be governed by and construed in accordance with the laws of the State of New York. The Trustee, the Company and each of the Subsidiary Guarantors agree to submit to the non-exclusive jurisdiction of the competent courts of the State of New York sitting in New York City in any action or proceeding arising out of or relating to the Indenture or the 7⅞% Notes.

SECTION 14. Counterparts. This Second Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original but such counterparts shall together constitute but one and the same instrument. This Second Supplemental Indenture may be executed by facsimile or other electronic transmission.

SECTION 15. Trustee Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the 7⅞% Notes, except the Trustee’s certificate of authentication, shall be taken as the statements of the Company and Opco, and the Trustee assumes no responsibility for their correctness. The Trustee makes no

representations as to the validity or sufficiency of this Second Supplemental Indenture or of the 7⅞% Notes. The Trustee shall not be accountable for the use or application by the Company of the 7⅞% Notes or the proceeds thereof.

SECTION 16. Supplemental Indenture Controls. In the event there is any conflict or inconsistency between the Original Indenture and this Second Supplemental Indenture, the provisions of this Second Supplemental Indenture shall control.

[The remainder of this page has been left blank.]
