(i) the sum of

(a) discounted future net revenues from proved oil and gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with SEC guidelines before any state, federal or foreign income taxes, as estimated in a reserve report prepared as of the end of the Company’s most recently completed fiscal year, which reserve report is prepared or reviewed by independent petroleum engineers as to reserves accounting for at least 80% of all such discounted future net revenues and by the Company’s petroleum engineers with respect to any other reserves covered by such report, as increased by, as of the date of determination, the estimated discounted future net revenues from (1) estimated proved oil and gas reserves acquired since such year-end, which reserves were not reflected in such year-end reserve report, and (2) estimated increases in proved oil and gas reserves since such year-end due to exploration, development or exploitation activities or due to changes in geological conditions or other factors which 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), and decreased by, as of the date of determination, the estimated discounted future net revenues from (3) estimated proved oil and gas reserves reflected in such year-end report produced

or disposed of since such year-end and (4) 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 which 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 (1) through (4), 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 (i)(a) shall be confirmed in writing an independent petroleum engineer, plus

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

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

(d) the greater of (1) the net book value on a date no earlier than the date of the Company’s latest annual or quarterly financial statements and (2) the appraised value, as estimated by independent appraisers, of other tangible assets (including, without duplication, Investments in unconsolidated Restricted Subsidiaries) of the Company and its Restricted Subsidiaries, as of the date no earlier than the date of the Company’s latest audited financial statements (provided that the Company shall not be required to obtain such appraisal of such assets if no such appraisal has been performed),

minus (ii) the sum of

(a) minority interests, plus

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

(c) to the extent included in (i)(a) above, the discounted future net revenues, calculated in accordance with SEC guidelines (utilizing the prices utilized in the Company’s year-end reserve report), attributable to reserves which are required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto) plus

(d) the discounted future net revenues, calculated in accordance with SEC guidelines, attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price assumptions included in determining the discounted future net revenues specified in (i)(a) above, would be necessary to fully satisfy the payment obligations of the Company and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments (determined, if applicable, using the schedules specified with respect thereto).

(3) Agent Members will have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary may be treated by the Company, any Guarantor, the Trustee and any agent of the Company, any Guarantor or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent Member) to take any action which a Holder is entitled to take under this Indenture or the Notes, and nothing herein will impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

(4) If (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for a Global Note and a successor depositary is not appointed by the Company within 90 days of the notice or (y) an Event of Default has occurred and is continuing and the Trustee has received a request from the Depositary, the Trustee will promptly exchange each beneficial interest in a Global Note for one or more Certificated Notes in authorized denominations and of like terms and tenor having an equal aggregate principal amount registered in the name of the owner of such beneficial interest, as identified to the Trustee by the Depositary, and thereupon such Global Note will be deemed canceled. If such Note does not bear the Restricted Legend, then the Certificated Notes issued in exchange therefor will not bear the Restricted Legend. If such Note bears the Restricted Legend, then the Certificated Notes issued in exchange therefor will bear the Restricted Legend.

(d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized denomination and of like terms and tenor by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by Section 2.10. The Trustee will promptly register any transfer or exchange that meets the requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that

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

(y) the Trustee will not be required (i) to issue, register the transfer of or exchange any Note for a period of 15 days before a selection of Notes of like terms and tenor to be redeemed or purchased pursuant to an Offer to Purchase, (ii) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of any Note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase is to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to register the transfer of or exchange any Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer, the Company, each Guarantor, the Trustee and their agents will

treat the Person in whose name the Note is registered as the owner and Holder thereof for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary.

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

No service charge will be imposed in connection with any transfer or exchange of any Note, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange pursuant to subsection (b)(4)).

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

(2) Global Note to Certificated Note. If a beneficial interest in a Global Note is transferred or exchanged for a Certificated Note, the Trustee will (x) record a decrease in the principal amount of such Global Note equal to the principal amount of such transfer or exchange and (y) deliver one or more new Certificated Notes in authorized denominations and of like terms and tenor having an equal aggregate principal amount to the transferee (in the case of a transfer) or the owner of such beneficial interest (in the case of an exchange), registered in the name of such transferee or owner, as applicable.

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

Certificated Notes in authorized denominations and of like terms and tenor having an aggregate principal amount equal to the untransferred or unexchanged portion of the canceled Certificated Note, registered in the name of the Holder thereof.

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

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

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

(c) No certification is required in connection with any transfer or exchange of any Note (or a beneficial interest therein)

(1) after such Note is eligible for resale pursuant to Rule 144(d) under the Securities Act (or a successor provision); provided that the

Company has provided the Trustee with an Officers’ Certificate to that effect, and the Company may require from any Person requesting a transfer or exchange in reliance upon this clause (1) an opinion of counsel and any other reasonable certifications and evidence in order to support such certificate; or

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

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

Section 3.01. Optional Redemption. The Notes may be redeemed as set forth in Section 5 of the form of Notes.

Section 3.02. [Reserved].

Section 3.03. Method and Effect of Redemption. (a) If the Company elects to redeem Notes, it must notify the Trustee of the redemption date and the principal amount of Notes to be redeemed by delivering an Officers’ Certificate at least 10 days before the notice of redemption required pursuant to this Section 3.03(a) is sent to Holders (unless a shorter period is satisfactory to the Trustee). If fewer than all of the Notes are being redeemed, the Officers’ Certificate must also specify a record date not less than 15 days after the date the notice of redemption is sent to Holders, and the Trustee will select the Notes to be redeemed pro rata, by lot or by any other method the Trustee in its sole discretion deems fair and appropriate, in denominations of $1,000 principal amount and multiples thereof. The Trustee will notify the Company promptly of the Notes or portions of Notes to be called for redemption. Notice of redemption must be sent by the Company or at the Company’s request, by the Trustee in the name and at the expense of the Company, to Holders whose Notes are to be redeemed at least 30 days but not more than 60 days before the redemption date.

(1) the redemption date;

(2) the redemption price, including the portion thereof representing any accrued interest;

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

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

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

(6) if any Note is redeemed in part, on and after the redemption date, upon surrender of such Note, new Notes of like terms and tenor equal in principal amount to the unredeemed portion will be issued; and

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

(c) Once notice of redemption is sent to the Holders, Notes called for redemption become due and payable at the redemption price on the redemption date, and upon surrender of the Notes called for redemption, the Company shall redeem such Notes at the redemption price. Commencing on the redemption date, if funds are deposited by the Company to pay the redemption price for the Notes as provided herein, the Notes redeemed will cease to accrue interest. Upon surrender of any Note redeemed in part, the Holder will receive a new Note of like terms and tenor equal in principal amount to the unredeemed portion of the surrendered Note.

Section 3.04. Offer to Purchase. (a) An “Offer to Purchase” means an offer by the Company to purchase Notes as required by this Indenture. An Offer to Purchase must be made by written offer (the “offer”) sent to the Holders.

(3) the purchase price, including the portion thereof representing accrued interest;

(4) an expiration date (the “expiration date”) not less than 30 days or more than 60 days after the date of the offer, and a settlement date for purchase (the “purchase date”) not more than five Business Days after the expiration date;

(5) a Holder may tender all or any portion of its Notes, subject to the requirement that any portion of a Note tendered must be in a multiple of $1,000 principal amount;

(6) the place or places where Notes are to be surrendered for tender pursuant to the Offer to Purchase;

(7) each Holder electing to tender a Note pursuant to the offer will be required to surrender such Note at the place or places specified in the offer prior to the close of business on the expiration date (any such Certificated Note being, if the Company or the Trustee so requires, duly endorsed or accompanied by a duly executed written instrument of transfer);

(8) interest on any Note not tendered, or tendered but not purchased by the Company pursuant to the Offer to Purchase, will continue to accrue;

(9) on the purchase date the purchase price will become due and payable on each Note accepted for purchase, and interest on Notes purchased will cease to accrue on and after the purchase date;

(12) if any Note is purchased in part, new Notes equal in principal amount to the unpurchased portion of the Note will be issued; and

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

(c) Prior to the purchase date, the Company will accept tendered Notes for purchase as required by the Offer to Purchase and deliver to the Trustee all Notes so accepted together with an Officers’ Certificate specifying which Notes have been accepted for purchase. On the purchase date the purchase price will become due and payable on each Note accepted for purchase, and interest on Notes purchased will cease to accrue on and after the purchase date. The Trustee will promptly return to Holders any Notes not accepted for purchase and send to Holders new Notes of like terms and tenor equal in principal amount to any unpurchased portion of any Notes accepted for purchase in part.

(d) The Company will comply with Rule 14e-1 under the Exchange Act and all other applicable laws in making any Offer to Purchase, and the above procedures will be deemed modified as necessary to permit such compliance.

(e) The Company will timely repay Indebtedness or obtain consents as necessary under, or terminate, any agreements or instruments that would otherwise prohibit an Offer to Purchase required to be made pursuant to this Indenture.

Agent, it will, on or before each due date, segregate and hold in a separate trust fund for the benefit of the Holders a sum of money sufficient to pay such amounts until paid to such Holders or otherwise disposed of as provided in this Indenture. In each case the Company will promptly notify the Trustee of its compliance with this paragraph.

The Company hereby initially designates the Corporate Trust Office of the Trustee as such office of the Company. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served to the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be surrendered or presented for any of such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence and the existence of each of its Restricted Subsidiaries in accordance with their respective organizational documents, and the material rights, licenses and franchises of the

Section 4.04. Payment of Obligations. The Company will pay or discharge, and cause each of its Restricted Subsidiaries to pay or discharge as the same shall become due and payable (i) all material tax liabilities, assessments and governmental charges or levies upon it or its properties or assets, unless the same are being contested in good faith by appropriate proceedings diligently conducted and adequate reserves in accordance with GAAP are being maintained by the Company or such Restricted Subsidiary, and (ii) all material lawful claims which, if unpaid, would by law become a Lien upon the property of the Company or any Restricted Subsidiary.

Section 4.05. Maintenance of Properties and Insurance.

(b) The Company will maintain or cause to be maintained (at its own expense), for itself and its Restricted Subsidiaries, insurance with financially sound and reputable insurance companies, in such amounts, with such limitations or deductibles, against such risks, and in such form as is customarily maintained by companies of established repute engaged in the same or similar businesses operating in the same or similar locations.

Section 4.06. Limitation on Indebtedness and Disqualified Stock. (a) The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, create, issue, incur, assume, guarantee or otherwise in any manner become directly or indirectly liable for the payment of or otherwise incur, contingently or otherwise (collectively, “incur”), any Indebtedness (including any Acquired Debt and the issuance of Disqualified Stock), unless such Indebtedness is incurred by the Company or any Guarantor and, in each case, the Company’s Consolidated Fixed Charge Coverage Ratio for the most recent four full fiscal quarters for which financial statements are available immediately preceding the incurrence of such Indebtedness taken as one period is at least equal to or greater than 2.25:1.

(B)(i) any subsequent issuance or transfer of Capital Stock that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary thereof (other than pursuant to a Credit Facility) and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary thereof, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (4);

(5) Guarantees by the Company or any Guarantor of any Indebtedness of the Company or any of the Guarantors which is permitted to be incurred under this Indenture;

(11) Permitted Refinancing Indebtedness of the Company or any Restricted Subsidiary issued in exchange for, or the net proceeds of which are used to renew, extend, substitute, defease, refund, refinance or replace, any Indebtedness, including any Disqualified Stock, incurred pursuant to Section 4.06(a) and clause (2), (3), (7), (11) or (12) of this Section 4.06 (b);

(14) Indebtedness of the Company or any Restricted Subsidiary in addition to that described in clauses (1) through (13) above, and any renewals, extensions, substitutions, refinancings or replacements of such Indebtedness, so long as the aggregate principal amount of all such Indebtedness shall not exceed $40,000,000 outstanding at any one time in the aggregate.

(c) For purposes of determining compliance with this Section, in the event that an item of Indebtedness meets the criteria of more than one of the types of Indebtedness permitted by this Section, the Company in its sole discretion may classify or reclassify such item of Indebtedness and only be required to include the amount of such Indebtedness as one of such types (or to divide such Indebtedness between two or more of such types); provided that any Indebtedness

under the Senior Credit Facility which was in existence on the Prior Issue Date (after giving effect to the application of the net proceeds from the Prior Notes) shall be deemed to have been incurred pursuant to clause (1) of subsection (b) above rather than subsection (a) above.

(d) Indebtedness permitted by this Section need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such Indebtedness.

(e) Accrual of interest, accretion of principal or liquidation preference (or similar amount) in respect of Preferred Stock or amortization of original issue discount, and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the accretion or payment of dividends on any Disqualified Stock or Preferred Stock in the form of additional shares of the same class of Disqualified Stock or Preferred Stock will not be deemed to be an incurrence of Indebtedness for purposes of this covenant; provided, in each such case, that the amount thereof as accrued shall be included as required in the calculation of the Consolidated Fixed Charge Coverage Ratio of the Company.

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

(g) If Indebtedness is secured by a letter of credit that serves only to secure such Indebtedness, then the total amount deemed incurred shall be equal to the greater of (x) the principal of such Indebtedness and (y) the amount that may be drawn under such letter of credit.

(h) The amount of Indebtedness issued at a price less than the amount of the liability thereof shall be determined in accordance with GAAP.

Section 4.07. Limitation on Restricted Payments. (a) The Company will not, and will not cause or permit any Restricted Subsidiary to, directly or indirectly:

ARTICLE 6

DEFAULT AND REMEDIES

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

(2) the Company defaults in the payment of interest (including any Additional Interest) on any Note when the same becomes due and payable, and the default continues for a period of 30 days;

(3) the Company fails to make an Offer to Purchase and thereafter accept and pay for Notes tendered when and as required pursuant to Section 4.13 or Section 4.14, or the Company or any Guarantor fails to comply with Article 5;

(4) the Company defaults in the performance of or breaches any other covenant or agreement of the Company in this Indenture or under the Notes and

the default or breach continues for a period of 60 consecutive days after written notice (or 180 consecutive days after written notice in the case of a Default pursuant to Section 4.20) to the Company by the Trustee or to the Company and the Trustee by the Holders of 25% or more in aggregate principal amount of the Notes;

(5) there occurs with respect to any Indebtedness of the Company, any Guarantor or any other Significant Subsidiary having an outstanding principal amount of $50,000,000 or more in the aggregate for all such Indebtedness of all such Persons (i) an event of default that results in such Indebtedness (including any scheduled installment of principal with respect to such Indebtedness) being due and payable prior to its Stated Maturity or (ii) failure to make a principal, premium (if any) or interest payment when due and such defaulted payment is not made, waived or extended within the applicable grace period, the result of which is to give the holder of such Indebtedness the right to accelerate such Indebtedness;

(6) one or more judgments, orders or decrees of any court or regulatory or administrative agency for the payment of money in excess of $50,000,000 (determined net of any amounts covered by insurance policies by insurers believed by the Company in good faith to be credit-worthy), either individually or in the aggregate, shall be rendered against the Company, any Guarantor or any other Significant Subsidiary or any of their respective properties and shall not be discharged and either (i) any creditor shall have commenced an enforcement proceeding upon such judgment, order or decree or (ii) there shall have been a period of 60 consecutive days during which a stay of enforcement of such judgment or order, by reason of an appeal or otherwise, shall not be in effect;

(7) the Company or any Significant Subsidiary institutes or consents to the institution of any proceeding under any Debtor Relief Law with respect to it, or makes an assignment for the benefit of creditors; or applies for or consents to the appointment of any receiver, trustee, custodian, conservator, liquidator, rehabilitator or similar officer for it or for all or any material part of its property; or any receiver, trustee, custodian, conservator, liquidator, rehabilitator or similar officer is appointed without the application or consent of such Person and the appointment continues undischarged or unstayed for 60 calendar days; or any proceeding under any Debtor Relief Law relating to any such Person or to all or any material part of its property is instituted without the consent of such Person and continues undismissed or unstayed for 60 calendar days, or an order for relief is entered in any such proceeding;

(8) the Company or any Significant Subsidiary becomes unable or admits in writing its inability or fails generally to pay its debts as they become due; or

(9) any Note Guarantee ceases to be in full force and effect, other than in accordance the terms of this Indenture, or a Guarantor denies or disaffirms its obligations under its Note Guarantee.

Section 6.02. Acceleration. (a) If an Event of Default occurs and is continuing under this Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Company (and to the Trustee if the notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of and accrued interest on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal and interest will become immediately due and payable;

provided, however, that upon the occurrence of an actual or deemed entry of an order for relief with respect to the Company under the Bankruptcy Code of the United States, the principal of and accrued interest on the Notes then outstanding will become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

(b) The Holders of a majority in aggregate principal amount of the outstanding Notes by written notice to the Company and to the Trustee may waive all past defaults and rescind and annul a declaration of acceleration and its consequences if

(1) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by the declaration of acceleration, have been cured or waived, and

(2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction.

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

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

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

Section 6.06. Limitation on Suits. A Holder may not institute any proceeding, judicial or otherwise, with respect to this Indenture or the Notes, or for the appointment of a receiver or trustee, or for any other remedy under this Indenture or the Notes, unless:

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

(2) Holders of at least 25% in aggregate principal amount of outstanding Notes have made written request to the Trustee to institute proceedings in respect of the Event of Default in its own name as Trustee under this Indenture;

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

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

Section 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal or interest specified in clause (1) or (2) of Section 6.01

occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust for the whole amount of principal and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent lawful, overdue installments of interest, in each case at the rate specified in the Notes, and such further amount as is sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee hereunder.

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

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

First: to the Trustee for all amounts due to it hereunder;

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

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

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

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

Section 6.12. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may require any party litigant in such suit (other than the Trustee) to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys fees, against any party litigant (other than the Trustee) in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by a Holder to enforce payment of principal of or interest on any Note on the respective due dates, or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Notes.

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

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

Section 6.15. Waiver of Stay, Extension or Usury Laws. The Company and each Guarantor covenants, to the extent that it may lawfully do so, that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company or the Guarantor from paying all or any portion of the principal of, or interest on, the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture. The Company and each

Guarantor hereby expressly waives, to the extent that it may lawfully do so, all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

(3) The deposit will not result in a breach or violation of, or constitute a default under any agreement or instrument (other than this Indenture) to which the Company is a party or by which it is bound.

(4) The Company has delivered to the Trustee either (x) a ruling received from the Internal Revenue Service to the effect that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would otherwise have been the case or (y) an Opinion of Counsel, based on a change in law after the date of this Indenture, to the same effect as the ruling described in clause (x).

(5) The Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, in each case stating that all conditions precedent provided for herein relating to the defeasance have been complied with.

Prior to the end of the 91-day period, none of the Company’s obligations under this Indenture will be discharged. Thereafter, the Trustee upon request will acknowledge in writing the discharge of the Company’s obligations under the Notes and this Indenture except for the surviving obligations specified above.

Section 8.03. Covenant Defeasance. After the 91^st day following the deposit referred to in clause (1) of this Section 8.03, the Company’s obligations set forth in Sections 4.06 through 4.18 inclusive, clauses (a), (b) and (c) of Section 4.20, and clauses (3) and (5) of Section 5.01(a), and each Guarantor’s obligations under its Note Guarantee, will terminate, and clauses (3), (4), (5), (6) and (9) of Section 6.01 will no longer constitute Events of Default, provided the following conditions have been satisfied:

(1) The Company has complied with clauses (1), (2), (3) and (5) of Section 8.02; and

(2) the Company has delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will

be subject to federal income tax on the same amount and in the same manner and at the same times as would otherwise have been the case.

Except as specifically stated above, none of the Company’s obligations under this Indenture, or any Guarantor’s obligations under its Note Guarantee, will be discharged.

Section 8.04. Application of Trust Money. Subject to Section 8.05, the Trustee will hold in trust the money or U.S. Government Obligations deposited with it pursuant to Section 8.01, 8.02 or 8.03, and apply the deposited money and the proceeds from deposited U.S. Government Obligations to the payment of principal of and interest on the Notes in accordance with the Notes and this Indenture. Such money and U.S. Government Obligations need not be segregated from other funds except to the extent required by law.

Section 8.05. Repayment to Company. Subject to Sections 7.07, 8.01, 8.02 and 8.03, the Trustee will promptly pay to the Company upon request any excess money held by the Trustee at any time and thereupon be relieved from all liability with respect to such money. The Trustee will pay to the Company upon request any money held for payment with respect to the Notes that remains unclaimed for two years, provided that, if any Certificated Note is then outstanding, before making such payment the Trustee may at the expense and written direction of the Company publish once in a newspaper of general circulation in New York City, or send to each Holder entitled to such money, notice that the money remains unclaimed and that after a date specified in the notice (at least 30 days after the date of the publication or notice) any remaining unclaimed balance of money will be repaid to the Company. After payment to the Company, Holders entitled to such money must look solely to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee with respect to such money will cease.

Section 8.06. Reinstatement. If and for so long as the Trustee is unable to apply any money or U.S. Government Obligations held in trust pursuant to Section 8.01, 8.02 or 8.03 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes will be reinstated as though no such deposit in trust had been made. If the Company makes any payment of principal of or interest on any Notes because of the reinstatement of its obligations, it will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held in trust.

(8) to conform the text of this Indenture or the Notes to any provision of the “Description of the Notes” section of the Offering Memorandum to the extent that such provision in such “Description of the Notes” section was intended to be a verbatim recitation of a provision of this Indenture or the Notes; or

(9) to make any other change that does not materially and adversely affect the rights of any Holder.

Section 9.02. Amendments With Consent of Holders. (a) Except as otherwise provided in Sections 6.02, 6.04 and 6.07 or paragraph (b), the Company, the Guarantors and the Trustee may amend, modify or supplement this Indenture and the Notes with the consent of the Holders of a majority in aggregate principal amount of the outstanding Notes, and the Holders of a majority in aggregate principal amount of the outstanding Notes by written notice to the Trustee may waive future compliance by the Company with any provision of this Indenture or the Notes.

(b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder affected, an amendment, modification, supplement or waiver may not

(1) reduce the principal amount of or change the Stated Maturity of any installment of principal of any Note,

(2) reduce the rate of or change the Stated Maturity of any interest payment on any Note,

(3) reduce the amount payable upon the optional redemption of any Note or change the times at which any Note may be redeemed or, once notice of redemption has been given, the time at which it must thereupon be redeemed,

(4) after the time an Offer to Purchase is required to have been made, reduce the purchase amount or purchase price, or extend the latest expiration date or purchase date thereunder,

(5) make any Note payable in money other than that stated in the Note,

(6) impair the right of any Holder of Notes to receive any principal payment or interest payment on such Holder’s Notes, on or after the Stated Maturity thereof, or to institute suit for the enforcement of any such payment,

After an amendment, modification, supplement or waiver under this Section becomes effective, the Company will send to the Holders affected thereby a notice briefly describing the amendment, modification, supplement or waiver. The Company will send copies of any documents pursuant to which any such amendment, modification, supplement or waiver has been effected to Holders upon request. Any failure of the Company to send such notice or copies, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, modification, supplement or waiver.

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

GUARANTEES

Section 11.01. The Guarantees. Subject to the provisions of this Article, each Guarantor hereby fully and unconditionally Guarantees, jointly and severally, on an unsecured basis, the full and punctual payment (whether at Stated Maturity, upon redemption, purchase pursuant to an Offer to Purchase or acceleration, or otherwise) of the principal of, premium, if any, and interest on, and all other amounts payable under, each Note, and the full and punctual payment of all other amounts payable by the Company under this Indenture. Upon failure by the Company to pay punctually any such amount, each Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in this Indenture.

Section 11.02. Guarantee Unconditional. The obligations of each Guarantor hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released, discharged or otherwise affected by

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

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

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

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

(5) any invalidity or unenforceability relating to or against the Company for any reason of this Indenture or any Note, or any provision of

applicable law or regulation purporting to prohibit the payment by the Company of the principal of or interest on any Note or any other amount payable by the Company under this Indenture; or

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

Section 11.03. Discharge; Reinstatement. Subject to Section 11.09, each Guarantor’s obligations hereunder will remain in full force and effect until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Company under this Indenture have been paid in full. If at any time any payment of the principal of, premium, if any, or interest on any Note or any other amount payable by the Company under this Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Guarantor’s obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

Section 11.04. Waiver by the Guarantors. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person.

Section 11.05. Subrogation and Contribution. Upon making any payment with respect to any obligation of the Company under this Article, the Guarantor making such payment will be subrogated to the rights of the payee against the Company with respect to such obligation, provided that the Guarantor may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any other Guarantor, with respect to such payment so long as any amount payable by the Company hereunder or under the Notes remains unpaid.

Section 11.06. Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Company under this Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of this Indenture are nonetheless payable by the Guarantors hereunder forthwith on demand by the Trustee or the Holders.

Section 11.07. Limitation on Amount of Guarantee. Notwithstanding anything to the contrary in this Article, each Guarantor, and by its acceptance of

Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Note Guarantee are limited to the maximum amount that would not render the Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

Section 11.08. Execution and Delivery of Guarantee. The execution by each Guarantor of this Indenture (or a Supplemental Indenture) evidences the Note Guarantee of such Guarantor, whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in this Indenture on behalf of each Guarantor.

Section 11.09. Release of Note Guarantee. The Note Guarantee of a Guarantor will terminate upon

(1) a sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of consolidation or merger) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition is permitted by this Indenture,

(2) a sale or other disposition of all or substantially all of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if the sale or other disposition is permitted by this Indenture,

(3) if the Note Guarantee was required pursuant to the terms of this Indenture, the cessation of the circumstances requiring the Note Guarantee,

(4) the designation in accordance with this Indenture of the Guarantor as an Unrestricted Subsidiary, or

(5) defeasance or discharge of the Notes, as provided in Article 8.

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