The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company, the Parent Guarantor and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. Notwithstanding the foregoing, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. (a) Global Notes. Series A Notes offered and sold to QIBs in reliance on Rule 144A shall be issued initially in the form of one or more 144A Global Notes, which shall be deposited on behalf of the purchasers of the Series A Notes represented thereby with the Note Custodian and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided. Series A Notes offered and sold to Institutional Accredited Investors shall be issued initially in the form of one or more IAI Global Notes, which shall be deposited on behalf of the purchasers of the Series A Notes represented thereby with the Note Custodian and registered in the name of the Depository or a nominee of the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided. Any Series A Notes transferred during the 40-day restricted period (as defined in Regulation S) offered and sold in reliance on Regulation S shall be issued initially in the form of the Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the 30 38 Series A Notes represented thereby with the Note Custodian and registered in the name of the Depository or the nominee of the Depository for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The "40-day restricted period" shall be terminated upon the receipt by the Trustee of (i) a written certificate from the Depository, together with copies of certificates from Euroclear and Clearstream certifying that they have received certification of non-United States beneficial ownership of 100% of the aggregate principal amount of the Regulation S Temporary Global Note (except to the extent of any beneficial owners thereof who acquired an interest therein pursuant to another exemption from registration under the Securities Act and who will take delivery of a beneficial ownership interest in a 144A Global Note or an IAI Global Note, all as contemplated by Section 2.06(a)(ii) or (iii) hereof), and (ii) an Officers' Certificate from the Company. Following the termination of the 40-day restricted period, beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in one or more Regulation S Permanent Global Notes pursuant to the Applicable Procedures. Simultaneously with the authentication of Regulation S Permanent Global Notes, the Trustee shall cancel the Regulation S Temporary Global Note. Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, installment payments, redemptions, repurchases and transfers of interests. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof. (b) Book-Entry Provisions. Participants shall have no rights either under this Indenture with respect to any Global Note held on their behalf by the Depository or by the Note Custodian as custodian for the Depository or under such Global Note, and the Depository (or its nominee, if the Depository is not the Holder) may be treated by the Company, the Trustee and any Agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any Agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in any Global Note. SECTION 2.02. EXECUTION AND AUTHENTICATION. One Officer shall sign the Notes for the Company by manual or facsimile signature. If the Company has a corporate seal, it may be reproduced on the Notes and, if so, it may be in facsimile form. If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid. 31 39 A Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee. Such signature shall be conclusive evidence that the Note has been authenticated under this Indenture. The form of Trustee's certificate of authentication to be borne by the Notes shall be substantially as set forth in Exhibit A-1 or A-2 hereto. Each Note shall be dated the date of its authentication. The Trustee shall authenticate (i) the Series A Notes for original issue on the Issue Date in the aggregate principal amount of $130,000,000 (the "Original Notes"), (ii) additional Series A Notes for original issue from time to time after the Issue Date in such principal amounts not to exceed $20,000,000 in the aggregate as may be set forth in a written order of the Company described in this sentence and (iii) the Series B Notes for original issue from time to time for issue only in exchange for a like principal amount of Series A Notes, in each case upon a written order of the Company signed by one Officer, which written order shall specify (a) the amount of Notes to be authenticated and the date of original issue thereof, (b) whether the Notes are Series A Notes or Series B Notes, and (c) the amount of Notes to be issued in global form or definitive form. The aggregate principal amount of Notes outstanding at any time may not exceed $130,000,000 plus such additional principal amounts as may be issued and authenticated pursuant to clause (ii) of this paragraph, except as provided in Section 2.07 hereof. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Notes. An authenticating agent may authenticate Notes 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 an Agent to deal with the Company, any Guarantor or an Affiliate of the Company. SECTION 2.03. REGISTRAR AND PAYING AGENT. The Company shall maintain an office or agency in the continental United States where Notes may be presented for registration of transfer or for exchange ("Registrar"). The Company shall also maintain an office or agency in the continental United States where Notes may be presented for payment ("Paying Agent"), which shall initially be the agency of the Trustee located in the Borough of Manhattan, New York, New York. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term "Registrar" includes any co-registrar and the term "Paying Agent" includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company shall notify the Trustee in writing of the name and address of any Agent not named in this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, and such agreement shall incorporate the TIA's provisions of this Indenture that relate to such Agent. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. The Company initially appoints The Depository Trust Company ("DTC") to act as Depository with respect to the Global Notes. 32 40 The Company initially appoints the Trustee to act as Registrar at its Corporate Trust Office, to act as Paying Agent at its agency in the Borough of Manhattan in New York, New York, and to act as Note Custodian with respect to the Global Notes. SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or premium, interest or Liquidated Damages, if any, on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon the occurrence and during the continuance of any Event of Default described in clause (h) or (i) of Section 6.01 hereof, the Trustee shall serve as Paying Agent for the Notes. SECTION 2.05. HOLDER LISTS. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven 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 the Holders of Notes and the Company shall otherwise comply with TIA Section 312(a).

If required by the Trustee and the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. If, after the delivery of such replacement Note, a bona fide purchaser of the original Note in lieu of which such replacement Note was issued presents for payment or registration such original Note, the Trustee shall be entitled to recover such replacement Note from the Person to whom it was delivered or any Person taking therefrom, except 39 47 a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company, the Trustee, any Agent and any authenticating agent in connection therewith. Subject to the provisions of the final sentence of the preceding paragraph of this Section 2.07, every replacement Note is an additional obligation of the Company and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. SECTION 2.08. OUTSTANDING NOTES. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interests in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company, the Parent Guarantor, any Subsidiary of the Parent Guarantor or an Affiliate of the Parent Guarantor holds the Note. If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

Notwithstanding the foregoing, Notes that the Company, the Parent Guarantor, a Subsidiary of the Parent Guarantor or an Affiliate of the Parent Guarantor offers to purchase or acquires pursuant to an offer, exchange offer, tender offer or otherwise shall not be deemed to be owned by the Company, the Parent Guarantor, a Subsidiary of the Parent Guarantor or an Affiliate of the Parent Guarantor until legal title to such Notes passes to the Company, such Subsidiary or such Affiliate as the case may be. SECTION 2.10. TEMPORARY NOTES. Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Company signed by one Officer of the Company. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee 40 48 shall authenticate definitive Notes in exchange for temporary Notes. Until such exchange, Holders of temporary Notes shall be entitled to all of the benefits of this Indenture. SECTION 2.11. CANCELLATION.

The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation, other than as contemplated by the Exchange Offer. SECTION 2.12. DEFAULT INTEREST. If the Company defaults in a payment of interest on the Notes, it shall pay the default interest in any lawful manner plus, to the extent lawful, interest payable on the default interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of default interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed each such special record date and payment date, provided, however, that no such special record date shall be less than 10 days prior to the related payment date for such default interest. At least 15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. ARTICLE 3 REDEMPTION AND REPURCHASE SECTION 3.01. NOTICES TO TRUSTEE. If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers' Certificate setting forth (i) the clause of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price.

In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided 41 49 herein, not less than 30 days nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The provisions of the two preceding paragraphs of this Section 3.02 shall not apply with respect to any redemption affecting only a Global Note, whether such Global Note is to be redeemed in whole or in part.

For purposes of this paragraph, "Excess Proceeds" means any Net Available Cash from Asset Dispositions remaining after investments in any Additional Assets or Replacement Assets as provided for in the preceding sentence. The Company may defer the Excess Proceeds Offer until there are aggregate unutilized Excess Proceeds equal to or in excess of $5,000,000 resulting from one or more Asset Dispositions (at which time the entire unutilized Excess Proceeds, and not just the amounts in excess of $5,000,000, shall be applied as required pursuant to the preceding paragraph). Notwithstanding the foregoing, in the event that the Parent Guarantor or any of the Restricted Subsidiaries consummates or causes to be consummated a single or a series of related Asset Dispositions representing more than 20% of the consolidated proved reserves of the Parent 54 62 Guarantor and the Restricted Subsidiaries (a "Major Asset Sale"), the Company shall make an offer to purchase (the "Major Asset Sale Offer") from the Holders on a pro rata basis an aggregate stated principal amount of Notes equal to 50% of the gross proceeds from such Major Asset Sale at a purchase price equal to 100% of the stated principal amount of such Notes, together with accrued interest (if any) to the date of purchase. Any Net Available Cash remaining following the completion of the Major Asset Sale Offer shall be applied to, within 270 days of the date of completion of the Major Asset Sale Offer, an Investment or Investments in Additional Assets or Replacement Assets. (b) In the event of the transfer of substantially all (but not all) the property and assets of the Parent Guarantor or the Company as an entirety to a Person in a transaction not constituting a Change of Control that is permitted by Section 5.01 hereof, the Successor Company shall be deemed to have sold the properties and assets of the Parent Guarantor or the Company, as applicable, not so transferred for purposes of this clause, and shall comply with the provisions of this clause with respect to such deemed sale as if it were an Asset Disposition and the Successor Company shall be deemed to have received Net Available Cash in an amount equal to the fair market value (as determined in good faith by the Board of Directors of the Parent Guarantor) of the properties and assets not so transferred or sold. (c) All Net Available Cash in excess of $1,000,000 in any fiscal year from any Asset Disposition involving Collateral shall constitute Trust Moneys and shall be delivered by the Parent Guarantor or the Company, as applicable, to the Collateral Agent and shall be deposited in the Collateral Account in accordance with the Intercreditor Agreement. Net Available Cash so deposited may be withdrawn from the Collateral Account for application by the Parent Guarantor or the Company in accordance with this clause or otherwise pursuant to this Indenture as described in the Intercreditor Agreement. SECTION 4.11. TRANSACTIONS WITH AFFILIATES. (a) The Parent Guarantor 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 stock, property, employee compensation arrangements or the rendering of any service) with any Affiliate of the Parent Guarantor (an "Affiliate Transaction") unless the terms thereof (1) are no less favorable to the Parent Guarantor 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 between $500,000 and $3,000,000, are certified in an Officers' Certificate to the effect that such Affiliate Transaction complies with this clause, and have been approved by a majority of the members of the Board of Directors of the Parent Guarantor having no personal stake in such Affiliate Transaction or (3) if such Affiliate Transaction involves an amount in excess of $3,000,000, are certified in an Officers' Certificate to the effect that such Affiliate Transaction complies with this clause, has been approved by a majority of the members of the Board of Directors of the Parent Guarantor having no personal stake in such Affiliate Transaction and has been determined by a nationally recognized investment banking firm to be fair, from a financial standpoint, to the Parent Guarantor or the Restricted Subsidiary, as the case may be. In addition, the net balance of advances made by the Parent Guarantor and the Restricted Subsidiaries to Richard Bowman and his Affiliates shall not exceed $150,000 for more than 30 consecutive days. 55 63 (b) The provisions of the preceding paragraph (a) shall not prohibit (i) reasonable fees and compensation paid to and indemnity provided on behalf of, officers, directors, employees or consultants of the Parent Guarantor or any Restricted Subsidiary as determined in good faith by the Board of Directors of the Parent Guarantor; (ii) transactions exclusively between or among the Restricted Subsidiaries; provided, however, that such transactions are not otherwise prohibited by this Indenture; and (iii) Restricted Payments permitted by this Indenture.

SECTION 4.15. OFFER TO PURCHASE UPON CHANGE OF CONTROL. (a) Upon the occurrence of a Change of Control, the Company shall make an offer (a "Change of Control Offer") to purchase all or any portion (equal to $1,000 or an integral multiple thereof) of each Holder's Notes, at a purchase price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the date of purchase (the "Change of Control Payment").

If any of the Notes subject to a Change of Control Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to comply with the procedures of the Depository applicable to repurchases. Further, the Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Change of Control Offer, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described above by virtue thereof. (b) On or before 10:00 a.m. New York time on the Change of Control Payment Date, the Company shall, to the extent lawful, (a) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered and (c) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company.

The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. (c) The foregoing provisions of this Section 4.15 that require the Company to make a Change of Control Offer following a Change of Control shall be applicable regardless of whether any other provisions of this Indenture are applicable. The Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. 57 65 SECTION 4.16.

The Company must commence its Excess Cash Flow Offer not later than the date on which the certificate computing the Excess Cash Flow is delivered to the Trustee. If the aggregate purchase price for the Notes (exclusive of interest) tendered pursuant to such Excess Cash 58 66 Flow Offer is less than the Excess Cash Flow, then the Parent Guarantor and the Restricted Subsidiaries may use the remaining Excess Cash Flow for general corporate purposes not prohibited by the terms of this Indenture.

The Company shall make a public announcement of the results of the Excess Cash Flow Offer as soon as practicable after the Excess Cash Flow Payment Date. For the purposes of this covenant, the Trustee shall act as the Paying Agent. Each Excess Cash Flow Offer shall be conducted in compliance with all applicable laws, including without limitation, Regulation 14E of the Exchange Act and the rules thereunder and all other applicable federal and state securities laws.

The Parent Guarantor shall not, and shall not permit any of the Restricted Subsidiaries to, engage in the conduct of any business other than the Oil and Gas Business. SECTION 4.22. LIMITATION ON IMPAIRMENT OF LIEN.

Neither the Parent Guarantor nor any of the Restricted Subsidiaries will enter into any agreement or instrument that by its terms requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness, other than pursuant to this Indenture and the Security Documents. SECTION 4.23. LIEN ON ADDITIONAL COLLATERAL. (a) If, after the Closing Date, the Parent Guarantor or any of the Restricted Subsidiaries shall (i) acquire any (x) Oil and Gas Assets or (y) other assets as non-cash consideration for any Asset Disposition or (ii) engage in successful drilling and exploration activities resulting in the creation of new proved oil and gas reserves having a PV-10 Value in excess of $500,000, then the Parent Guarantor shall, and shall cause each of the Restricted Subsidiaries to, execute and file in the appropriate filing offices additional Security Documents granting to the Collateral Agent for the benefit of the Approved Hedge Counterparties or Hedge Liquidity Providers (as applicable), the Trustee and the Holders a first Lien, subject only to Permitted Liens (or in the case of property securing Acquired Indebtedness, to the extent not prohibited by the terms of the instruments creating such Acquired Indebtedness, a junior Lien), as is necessary or appropriate to ensure that the Lien of this Indenture and the Security Documents covers substantially all of such new assets. (b) Without limitation of clause (a), on the date any Oil and Gas Assets or interests in a Permitted Joint Venture shall be acquired in exchange for or replacement of any Collateral, the Parent Guarantor shall, and shall cause each of the Restricted Subsidiaries to, execute and file in the appropriate filing offices additional Security Documents granting to the Collateral Agent, for the benefit of the Approved Hedge Counterparties or Hedge Liquidity Providers (as applicable), the Trustee and the Holders, a first Lien, subject only to Permitted Liens (or in the case of property securing Acquired Indebtedness, to the extent not prohibited by the terms of the instruments creating such Acquired Indebtedness, a junior Lien), on such portion of such assets as is necessary to ensure that the Lien of this Indenture and the Security Documents covers substantially all of such assets received in exchange or trade or on such interests in such Permitted Joint Venture.

If substantially all of such assets are not then subject to the 61 69 Lien of this Indenture and the Security Documents, then the Parent Guarantor shall, and shall cause the Restricted Subsidiaries to, execute and file in the appropriate filing offices additional Security Documents granting to the Collateral Agent for the benefit of the Approved Hedge Counterparties or Hedge Liquidity Providers (as applicable), the Trustee and the Holders a first Lien, subject only to Permitted Liens (or in the case of property securing Acquired Indebtedness, to the extent not prohibited by the terms of instruments creating such Acquired Indebtedness, a junior Lien), as is necessary or appropriate to encumber substantially all such assets.

HEDGING OBLIGATIONS. The Company and/or a Restricted Subsidiary will enter into and maintain Oil and Gas Hedging Contracts with an Approved Hedge Counterparty pursuant to which the Company and/or a Restricted Subsidiary will receive a fixed price payment or a minimum floor price so that at all times from the first day of the month following the month in which the Closing Date occurs (subject to the availability of hedge contracts) to July 1, 2006, the Parent Guarantor and/or a Restricted Subsidiary will have a Hedged Revenue Ratio of not less than 3.0 to 1.0 as of the first Business Day of each month for the then current Hedge Period; provided that: (i) in no event shall the Company and/or a Restricted Subsidiary enter into Oil and Gas Hedging Contracts that, when in effect, hedge aggregate volumes in excess of 80% of (A) the Projected Proved Developed Producing Production of each of crude oil and natural gas and (B) the Projected Proved Developed Producing Production of both crude oil and natural gas, in each case, from the Oil and Gas Assets of the Company and/or the Restricted Subsidiaries for the then current Hedge Period and each month in the then current Hedge Period, except that the Company and/or a Restricted Subsidiary may enter into Oil and Gas Hedging Contracts which are price floor contracts, options for a price floor or other similar arrangements (and for which neither the Company nor any Restricted Subsidiary has any liability other than the payment of an initial premium price) which, with all Oil and Gas Hedging Contracts then in effect, result in the aggregate volumes exceeding 80% (but in no event in excess of 100%) of the Projected Proved Developed Producing Production of each of oil and natural gas of the Company and the Restricted Subsidiaries; (ii) any Oil and Gas Hedging Contract executed pursuant to this Section 4.25 may be terminated (for any reason) without violation of this Section 4.25 if either (A) termination is required pursuant to clause (iv) below or (B) a replacement Oil and Gas Hedging Contract with an Approved Hedge Counterparty is entered into such that, after giving effect to such termination and the execution and delivery of such replacement Oil and Gas Hedging Contract, the Hedged Revenue Ratio is not less than 3.0 to 1.0, subject to clause (i) of this Section 4.25; (iii) if, as of any date of determination, NYMEX prices available for natural gas (Henry Hub) and crude oil (West Texas Intermediate) are less than $2.75 per MMBtu of natural gas (Henry Hub) or $18.00 per barrel of crude oil (West Texas Intermediate) for the one or more months during the then current Hedge Period (such period during which such prices are not available being the "Make-Up Period"), then the Hedged Revenue Ratio shall not be tested during such Make-Up Period, and as soon thereafter as available hedge prices for such Make-Up Period or any month during such Make-Up Period exceed the relevant minimum levels, then the Company and/or a Restricted Subsidiary shall be required to have a Hedged Revenue Ratio for the then current Hedge Period of not less than 3.0 to 1.0, subject to clause (i) of this Section 4.25; and (iv) in the event of any sale, exchange or other disposition of Oil and Gas Assets by the Company and/or any Restricted Subsidiary, the Company and/or a Restricted Subsidiary shall calculate its Hedged Revenue Ratio on a pro forma basis (to exclude the Oil 63 71 and Gas Asset disposed of utilizing the Projected Proved Developed Producing Production for such asset reflected in the most recently delivered Reserve Report) as of the first day of the month during which such sale, exchange or other disposition occurred for the Hedge Period commencing on such date and shall either (A) be in compliance with this Section 4.25 as of such day for the entirety of such Hedge Period or (B) terminate one or more Oil and Gas Hedging Contracts such that after giving effect to such termination, it would be in compliance with this Section 4.25. Notwithstanding anything herein to the contrary, the Company and/or a Restricted Subsidiary will enter into Oil and Gas Hedging Contracts for ordinary business purposes, to hedge their and the Restricted Subsidiaries' actual exposure to fluctuations in commodity prices and not for speculative purposes. For the avoidance of doubt, it is the intention of the parties that if (a) as of the first Business Day of each month for the then current Hedge Period the Hedged Revenue Ratio is less than 3.0 to 1.0, and (b) a Reserve Report is delivered which indicates an increase in the Projected Proved Producing Production for any month or months in the then current Hedge Period or in the aggregate Projected Proved Producing Production, then the Company and/or a Restricted Subsidiary shall be obligated to enter into and maintain incremental Oil and Gas Hedging Contracts with an Approved Hedge Counterparty to hedge incremental volumes such that it has either met the minimum Hedge Revenue Ratio of 3.0 to 1.0 or hedged the maximum amount of revenue for each month in the then current Hedge Period possible without violating the volume caps established in clause (i) of this Section 4.25.

ARTICLE 6 DEFAULTS AND REMEDIES SECTION 6.01. EVENTS OF DEFAULT.

(e) the Company, the Parent Guarantor or any Subsidiary Guarantor fails to comply with any other agreement in this Indenture, the Notes or any Security Document for 60 days after the Company receives written notice of such failure from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding; (f) a default occurs under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Parent Guarantor or any Restricted Subsidiary (or the payment of which is guaranteed by the Parent Guarantor or any Restricted Subsidiary), whether such Indebtedness or guarantee now exists, or is created after the date of this Indenture, which default (i) is caused by a failure to pay principal of or premium or interest on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness, including any extension thereof (a "Payment Default") or (ii) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, 67 75 aggregates in excess of $5,000,000; and provided, further, that if such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, an Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; (g) a judgment or decree for the payment of money in excess of $5,000,000 is rendered against the Parent Guarantor or any Restricted Subsidiary and such judgment decree is not paid or discharged for a period (during which execution shall not be effectively stayed, discharged or waived within 10 days after notice from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding) of 60 days; (h) the Guaranty Agreement or any Security Document ceases to be in full force and effect (other than in accordance with the terms of such Guaranty Agreement or Security Document) or the Parent Guarantor, the Company or a Subsidiary Guarantor denies or disaffirms its obligations under any Security Document to which it is a party or the Guaranty Agreement, as applicable, if such default continues for a period of 10 days after notice from the Trustee or any Holder to the Company; or (i) the Parent Guarantor or any Restricted Subsidiary pursuant to or within the meaning of Bankruptcy Law: (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, (iv) makes a general assignment for the benefit of its creditors, or (v) generally is not paying its debts as they become due;

or 68 76 (iii) orders the liquidation of the Parent Guarantor or any Restricted Subsidiary; and the order or decree remains unstayed and in effect for 60 consecutive days; (k) a material breach of the representations or warranties contained in any Security Document or in this Indenture or a material misstatement in any certification provided pursuant to any Security Document or this Indenture after notice from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding occurs and such breach continues unremedied for a period of 30 days. SECTION 6.02. ACCELERATION. If any Event of Default occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes may, by notice to the Company and the Trustee, and the Trustee shall, upon the request of such Holders, declare all the Notes to be due and payable immediately at 100% of the principal amount thereof. Upon any such declaration, the Notes shall become due and payable immediately at 100% of the principal amount thereof. Notwithstanding the foregoing, if an Event of Default specified in clause (i) or (j) of Section 6.01 hereof occurs with respect to the Parent Guarantor or any Restricted Subsidiary, all outstanding Notes shall be due and payable immediately at 100% of the principal amount thereof without further action or notice. The Holders of a majority in principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest, premium or Liquidated Damages, if any, that have become due solely because of such acceleration) have been cured or waived. If an Event of Default occurs by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Notes pursuant to Section 3.07(a) hereof, then, upon acceleration of the Notes, an equivalent premium shall also become and be immediately due and payable, to the extent permitted by law, anything in this Indenture or in the Notes to the contrary notwithstanding. SECTION 6.03. OTHER REMEDIES. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of and premium, interest and Liquidated Damages, if any, on the Notes or to enforce the performance of any provision of the Notes, this Indenture or the Guaranty Agreement. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right 69 77 or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. SECTION 6.04. WAIVER OF PAST DEFAULTS. Holders of a majority in principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of or premium, interest or Liquidated Damages, if any, on the Notes (including in connection with an offer to purchase). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. SECTION 6.05. CONTROL BY MAJORITY. Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. SECTION 6.06. LIMITATION ON SUITS. A Holder of a Note may pursue a remedy with respect to this Indenture, the Notes or the Guaranty Agreement only if: (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee reasonable security or indemnity satisfactory to the Trustee against any loss, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and (e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. No Holder may enforce any right or remedy provided in any Security Document (other than the Guaranty Agreement). Such rights and remedies will be enforced by the Collateral Agent subject to the terms of the Intercreditor Agreement. A Holder of a Note may not use this Indenture to 70 78 prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. SECTION 6.07. RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of and premium, interest and Liquidated Damages, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.08. COLLECTION SUIT BY TRUSTEE. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company, the Parent Guarantor or any Subsidiary Guarantor for the whole amount of principal of, premium, interest and Liquidated Damages, if any, remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and Liquidated Damages, if any, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 71 79 SECTION 6.10. PRIORITIES. If the Trustee collects any money pursuant to this Article or receives any moneys under the Intercreditor Agreement, it shall pay out the money in the following order: First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the Trustee's reasonable costs and expenses of collection; Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, interest and Liquidated Damages, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, interest and Liquidated Damages, if any, 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 Holders of Notes pursuant to this Section 6.10. SECTION 6.11. UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. ARTICLE 7 TRUSTEE SECTION 7.01. DUTIES OF TRUSTEE. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company's use of the 74 82 proceeds from the Notes or any money paid to the Company or upon the Company's direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. SECTION 7.05. NOTICE OF DEFAULTS. If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of or premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is not opposed to the interests of the Holders of the Notes. SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES. Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313(b)(2) and Section 313(b)(1). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). Commencing at the time this Indenture is qualified under the TIA, a copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange. SECTION 7.07. COMPENSATION AND INDEMNITY. The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Company and the Guarantors shall indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, any Guarantor or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence, bad faith or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek 75 83 indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company or the Guarantors of their obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The obligations of the Company and the Guarantors under this Section 7.07 shall survive the satisfaction and discharge of this Indenture. To secure the Company's payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(i) or (j ) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any applicable bankruptcy law. The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable. SECTION 7.08. REPLACEMENT OF TRUSTEE. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: (a) the Trustee fails to comply with Section 7.10 hereof; (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any applicable bankruptcy law; (c) a Custodian or public officer takes charge of the Trustee or its property; or (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal 76 84 amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee, after written request by any Holder of a Note who has been a Holder of a Note for at least six months, fails to comply with Section 7.10 hereof, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of 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 Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. SECTION 7.09.

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) Subject to Sections 8.01(c) and 8.02, (i) the Company at any time may terminate all its obligations under the Notes and this Indenture and all of the obligations of the Parent Guarantor and the Subsidiary Guarantors under the Guaranty Agreement and this Indenture ("Legal Defeasance") or (ii) the Company and the Parent Guarantor may terminate (a) their obligations contained in Article 4 hereof (other than those in Sections 4.01, 4.02, 4.05, 4.06 and 4.14); (b) the operation of Sections 6.01(f), 6.01(i) and (j) (with respect to Restricted Subsidiaries only) and 6.01(g) hereof and (c) the limitations contained in clauses (iv) and (v) of Section 5.01(a) hereof and clauses (iii) and (iv) of Section 5.01(b) hereof ("Covenant Defeasance"). 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 Notes may not be accelerated because of an Event of Default with respect thereto. If the Parent Guarantor and the Company exercise their Covenant Defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in Section 6.01(d), 6.01(e), 6.01(f), 6.01(g), 6.01(i) (but only with respect to Restricted Subsidiaries), 6.01(j) (but only with respect to Restricted Subsidiaries) or because of the failure to comply with Section 5.01(a)(iv) and (v) and 5.01(b)(iii) and (iv). If the Company exercises its Legal Defeasance option or its Covenant Defeasance option, the Parent Guarantor and each Subsidiary Guarantor, if any, will be released from all its obligations with respect to its Guarantee, and the Lien of the Security Documents will also be released. 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.

If the Trustee or Paying Agent is unable to apply any money or United States Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or other prohibiting such application, then the Company's obligations under this Indenture and the Notes and any Security Documents shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or United States Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or Liquidated Damages, if any, or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or United States Government Obligations held by the Trustee or Paying Agent. 80 88 ARTICLE 9 AMENDMENT, SUPPLEMENT AND WAIVER SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF NOTES. Notwithstanding Section 9.02 of this Indenture, the Company, the Parent Guarantor and the Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note: (a) to cure any ambiguity, omission, defect or inconsistency; (b) to provide for uncertificated Notes in addition to or in place of certificated Notes; (c) to provide for the assumption of the Company's obligations to the Holders of the Notes pursuant to Article 5 hereof; (d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not materially adversely affect the legal rights hereunder of any Holder of the Note; or (e) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA. Upon the request of the Company accompanied by a resolution of the Board of Directors of the Parent Guarantor authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company and the Parent Guarantor in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. SECTION 9.02. WITH CONSENT OF HOLDERS OF NOTES. Except as provided below in this Section 9.02, the Company, the Parent Guarantor and the Trustee may amend or supplement this Indenture and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a tender offer or exchange offer for the Notes). 81 89 Upon the request of the Company accompanied by a resolution of the Board of Directors of the Parent Guarantor authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Company and the Parent Guarantor in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each Holder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder): (a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; (b) reduce the rate of or extend the time for payment of interest on any Note; (c) reduce the principal of or extend the Stated Maturity of any Note or alter any of the provisions with respect to the redemption or purchase of the Notes by the Company (except as provided in Sections 3.09, 4.10, 4.15 and 4.19 hereof); (d) waive a Default or Event of Default in the payment of principal of or premium, interest or Liquidated Damages, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); (e) make any Note payable in money other than that stated in the Notes; (f) make any change in the provisions of this Indenture relating to waivers of past Defaults or Events of Default or the rights of Holders of Notes to receive payments of principal of or premium, interest or Liquidated Damages, if any, on the Notes (except as permitted in clause (g) below); (g) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 4.10, 4.15 and 4.19 hereof); 82 90 (h) make any change in the ranking of the Notes relative to other Indebtedness of the Company in a manner adverse to the Holders of Notes; (i) make any change in the foregoing amendment provisions which require each Holder's consent or in the waiver provisions; or (j) release any Collateral from the Liens created pursuant to the Indenture and the Security Documents or release the Parent Guarantor or any Subsidiary Guarantor from any of its obligations under the Indenture or the Guaranty Agreement, as the case may be, in any case otherwise than in accordance with the terms of this Indenture, the Guaranty Agreement and the Security Documents. SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect. SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. SECTION 9.05. NOTATION ON OR EXCHANGE OF NOTES. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. SECTION 9.06. TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture until the Board of Directors of the Parent Guarantor approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled 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 the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 83 91 ARTICLE 10 GUARANTEES OF NOTES SECTION 10.01.
